- the allowable construction height is reduced by 10m, that is, approximately 3 floors are reduced, which is a waste of land. Therefore, the present invention does not recommend the selection of a shear wall structure.
- the total thickness of the inner and outer leaf concrete is 0.1m to meet the fire resistance limit and bending compressive force requirements, and the cross-sectional area of the concrete column is approximately equivalent to that of the outer wall.

- the indoor sandwich thermal insulation partition damping wall of the ninth embodiment not only has a damping effect, but also solves the problem of heating and insulation requirements for households in a near zero energy building, and alleviates the problem of increasing the building height for floor insulation.
- the construction of a building with near zero energy consumption does not increase the height of the building due to thermal insulation requirements, which reduces the cost and saves land.
- the various external wall bodies of the tenth embodiment have a damping effect, and the cooperation with the damping wall of the indoor partition wall can effectively reduce the displacement of the building, especially the high-rise building, under the action of horizontal load, and the installation is simple.
- the eighth embodiment is to install elastomer materials between the foundation and the foundation.
- the impact of the seismic action on the superstructure will be greatly reduced from the bottom of the building.
- Buildings in areas with high seismic intensity can be considered; non-seismic fortified areas or earthquake-resistant
- For architecture it is recommended that implementation modes eight to ten be applied together.

It is considered that the designed wall has all-round advantages, and it is also conducive to building energy dissipation and shock absorption.
- the present invention recommends:
- the new construction is designed as a frame structure or a frame-core tube structure.
- the indoor partition wall or household partition wall is installed as a damping wall.
- the external wall is installed with a lightweight concrete sandwich wall with the aforementioned comprehensive advantages to eliminate all kinds of heat.

- the wind only meets the requirements of building energy saving for fixed installation of external wall panels; this recommendation is adopted for existing frame structures that can be removed from the original masonry wall.
- the damping partition wall and the damping external wall panel of the implementation modes 9 and 10 are used for the wall on the larger side of the calculated building displacement.
- the external wall panel can be fixedly installed, and the installation method of the fixed external wall panel is: after finding the verticality of the outer wall of the building, you can use the nail-type plastic anchor to install the external wall panel and the beam column or beam column Level the steel parts to fix, and use structural glue or cement polymer mortar to paste the external wall panels and beams and columns. You can also paste the EPS board at the larger gap between the external wall panels outside the beams and columns and the beams and columns to fill the gaps. Fireproof materials should be installed around the board to meet the fireproof requirements.

- Finite element software is a basic industrial software. It has been born for many years. The finite element software can analyze the internal forces of various parts of the building, and then reinforce the reinforcement according to the mechanics and concrete structure theory. As mentioned above, the inner and outer leaves are light-weight concrete external wall panels. When the exterior wall will not be destroyed. But now the construction industry does not require the use of finite element software to analyze the internal force of the block-filled wall of the frame structure, because in areas with high wind or seismic intensity, the block-filled wall cannot meet the data requirements calculated by the calculation software. The root cause of non-load-bearing wall damage during earthquakes and strong winds.
- the bending moment of the side wall of the window wall is 5-6 times that of the wall without opening, and the shear force at the corner of the window wall is the wall without opening.
- the body shear force is more than 10 times or even more than 30 times.

- the thermal conductivity of BFRP cloth is 0.035 ⁇ 0.04w/m ⁇ k. Installing BFRP cloth around doors and windows does not increase heat transfer. Installing BFRP cloth eliminates the thermal bridges of the walls around the doors and windows, and eliminates the thermal bridges of the sunshade and roller shutters.
- the anti-theft fence thermal bridge and the elimination of the external air conditioner pallet thermal bridge are one of the necessary conditions for promoting the construction of near-zero energy consumption buildings. Without installing BFRP cloth, you cannot move the window away from the base wall and install it near the outer corner of the window about 50mm. The thermal resistance of the outdoor cold spot from the wall surrounding the window cannot be less than the thermal resistance of the main wall, and the surrounding window wall cannot be eliminated.

- the minimum tensile strength standard value is 7.2t/m, considering the safety factor of 2, the tensile strength design value is 3.6t/m.
- the horizontal fiber of the BFRP cloth pasted on the side of the door and window is the horizontal drawbar of the door and window, that is, the shear-resistant steel hoops, which can ensure that the L-shaped embedded steel plate installed at the outer corner of the door and window is anchored to the installed windows, sunshade shutters, and anti-theft fence It can also prevent the non-load-bearing wall from tearing (shearing) the wall at the corner of the window under the action of the wind; the BFRP cloth is still a steel hoop along the building's circumference, which can increase the swing of the outer wall during an earthquake or strong wind
- the outer wall is safe (high-rise buildings swing particularly prominent), and the outer wall is more resistant to earthquake disasters.
- BFRP cloth is a green fiber with low price, which can greatly improve the durability of exterior walls.
- Paste non-combustible thermal insulation material on the EPS board of the external wall insulation layer, and paste BFRP cloth on the non-combustible thermal insulation material to protect the non-combustible thermal insulation material, and the adhesive is a waterproof material, which increases the service life of non-combustible thermal insulation materials and completely solves the common quality problems of external wall cracking and ingress of water; BFRP cloth is matched with other materials that have a durability life of no less than 50 years.

- the amount of cellulose ether MC added is appropriate for the viscosity of the prepared cement polymer mortar, and it is adjusted through experiments.
- Cellulose ether MC has good water retention.
- Cellulose ether MC should use methyl cellulose ether with good dispersibility and good water retention.

- Article 3 Interface agent Adhesive used to bond cement mortar or cast-in-place concrete to EPS board, or adhesive used to bond the sides of EPS board joints (excluding the sealing and waterproofing of the upper end of the roofing EPS board gap), commonly known as As the interface agent, a cement-based acrylate copolymer emulsion with strong adhesion, water resistance and excellent durability is selected, diluted with water, and an adhesive prepared by adding other materials.
- the powder is cement. Mix the cement (with 3% to 5% silica fume is suitable and mix well), add the cement to the prepared liquid material, add defoamer and dispersant, and mix the powder and liquid material evenly In the form of a thin paste, it is an interface agent.
- the interface agent applied to the EPS board should be moist and full, not easy to dry quickly, and not suitable for flow.
- the interface agent does not need to add sand, of course, adding sand to become cement polymer mortar can also be bonded, but it increases labor.
- the added amount of cement is small to facilitate painting, so it is necessary to add cellulose ether MC to the prepared liquid material to ensure the water retention of the adhesive, and adding cellulose ether MC to cement may not add enough cellulose ether MC , Can not play the role of water retention required.
- Tests are needed to prove that after applying the interface agent on the EPS board, apply cement mortar or pour concrete. After curing, the adhesive can penetrate into the EPS board by 3 ⁇ 5mm after curing. Surface, the damage should be on the EPS board, that is, the bonding is qualified. The bonding test should be carried out in advance, and the determined mix ratio should be safe. Or the interface agent of this article can be used in conjunction with the cement polymer mortar of article 2, and the interface agent of this article can be painted on the EPS board and then the cement polymer mortar of article 2 can be used for bonding.
- Acrylate copolymer emulsion can be processed into redispersible dry rubber powder, but in order to improve on-site instant dissolution during the production of redispersible dry rubber powder, polyvinyl alcohol needs to be added. Polyvinyl alcohol is very easy to biodegrade, so it is directly It is good to use emulsion adhesive. However, it does not rule out the use of redispersible dry rubber powder processed by acrylate copolymer emulsion. Tests have proved that it is possible to use redispersible dry rubber powder to bond reliably, but can it be confirmed whether the selected redispersible dry rubber powder can be confirmed It is difficult for the content of internal polyvinyl alcohol not to exceed the allowable value.

- the non-combustible thermal insulation material is vertical silk rock wool board or foamed cement board, which can be bonded with epoxy resin adhesive (fine sand can be added), or glued with cement polymer mortar according to Article 2 (sand when the sticking surface is flat For fine sand).
- cellulose ether MC (accounting for 1 to 2)% of the emulsion, and also add a pH regulator such as (AMP-95). It is advisable to test the diluted emulsion with a pH value of 8 or a little higher than 8, and then in neutral About (1-2)% of cellulose ether MC is added to the diluted emulsion, and it is viscous and stirred evenly. There is no need to add preservatives during preparation and use.

- the test is selected, and the emulsion is directly pasted after stirring. If no coupling agent can be added to achieve a good bonding effect, no coupling agent can be added.
- the BFRP cloth When the BFRP cloth is pasted on the inner leaf concrete on the side of the indoor window, if the inner leaf concrete is thinner, such as only 60mm, use a water-soluble emulsion adhesive to bond it. If the adhesive area is narrow and does not meet the shear resistance requirements, fiber impregnated structural adhesive can be used To paste BFRP cloth, it is necessary to verify that the BFRP cloth pasted with fiber impregnated structural glue meets the shear resistance requirements of the structural design requirements, or the BFRP cloth is pasted on the indoor side wall instead. Since all emulsions are easy to bond with concrete, this article does not need to emphasize that emulsions have strong adhesion.

- the glass transition temperature of the cement-based acrylic emulsion protoplasm and the second water-proof sealing material emulsion should not be higher than the local minimum temperature. It is forbidden to add water in the emulsion puree, because adding water will inevitably increase the powder and affect the elasticity of the waterproof sealing material.
- the water in the emulsion becomes thin after evaporation. Adding powder can increase the thickness, but the poor elasticity of the powder will also affect the adhesion to the EPS board. It is convenient to paint.
- the waterproof sealing material is applied twice at the gap and the interface agent of Article 3 is applied on the side when the roof EPS board is installed. It can ensure the waterproof and reliable.
- Polyacrylate emulsion or acrylate copolymer emulsion is the raw material for preparing JS waterproof coating. Adding powder is similar to preparing cement polymer waterproof coating.

Description
本发明是涉及建筑的一种高科技时代低碳社会的建筑技术,特别是可推动建设近零能耗建筑和全零能耗建筑,减少建筑建造和长期使用中碳排放,及保证建筑抗震抗风安全,减少地震破坏的建筑技术。是将建筑节能技术与抗震抗风技术相统一的建筑技术。The invention relates to a high-tech era low-carbon society building technology, in particular, it can promote the construction of near-zero energy buildings and zero-energy buildings, reduce carbon emissions in building construction and long-term use, and ensure that buildings are earthquake-resistant Wind safety, construction technology to reduce earthquake damage. It is a building technology that unifies building energy-saving technology and anti-seismic and wind-resistant technology.
当前建筑技术不适应高科技时代低碳社会的要求,如:The current construction technology does not meet the requirements of a low-carbon society in the high-tech era, such as:
1、防火不好、耐久性不好。中国和世界上其它国家时有发生薄抹灰保温墙体失火的火灾事故,对人民生命财产造成威胁。其试验标准条件是在室内进行,或在风力不大于三级的微风条件下进行。在大风时,特别是建筑越高风越大,一旦失火难保火灾不蔓延。大量的薄抹灰保温墙体防火不安全。而且薄抹灰墙体经常发生开裂进水的质量通病,高层建筑外墙维修面临严重负担,其它节能墙体热量节能保温效果更不好。1. Poor fire prevention and durability. In China and other countries in the world, fire accidents involving thin-plastered thermal insulation walls have occurred from time to time, threatening people's lives and property. The standard test conditions are carried out indoors or under breeze conditions with a wind force of no more than three levels. In strong winds, especially the higher the building, the greater the wind. Once a fire is caught, it is difficult to prevent the fire from spreading. A large number of thin plastered thermal insulation walls are not safe to fire. In addition, the common quality problems of cracking and water ingress of thin plastered walls often occur, and the maintenance of high-rise buildings faces a serious burden, and other energy-saving walls have a worse thermal and energy-saving insulation effect.
中国和世界能源形势严峻、环境形势严峻,无奈只得大量采用薄抹灰保温墙体,为此付出多少生命的代价和财产损失!The energy situation in China and the world is grim, and the environmental situation is grim. It has no choice but to use a large number of thin plaster thermal insulation walls. How much life and property losses have been paid for this!
2、热桥多,热桥是热量流失的通道,且导热系数再低的保温材料也不能消灭热桥。如窗口热桥,即使外墙保温层无限厚,窗口周边墙体保温层只能约20mm厚,热量就从窗口周边墙体流失,还有窗户附框热桥、遮阳卷帘安装件热桥、外墙附着物连接件热桥,幕墙装饰钢龙骨热桥、空调机混凝土托板热桥等。有反应说中国已建的被动房达不到预期的节能目标,这是很正常的,上述热桥增加的热耗谁能能算得清?这些热桥好似冰箱有洞一样,无论冰箱保温层多厚节能保温都不好。热桥增加的能耗往往超过《近零能耗建筑技术标准》GB/T51350规定的能耗限值。因为有大量的热桥导致保温层厚,外墙占地多浪费土地,造价高,建设节能90%的被动房用普通EPS板需要400mm厚,用哈尔滨鸿盛生产的800多元/m 3的EPS板需要厚300mm,还需要长途运输消耗能源。热桥使推进近零能耗建筑困难重重,特别是幕墙装饰的型钢龙骨热桥尤其严重!导致公共建筑建设节能65%的建筑都很困难,是建筑节能的大难题。屋面各层材料之间不粘接,屋面防水耐久性不好,且屋面漏雨不知是哪漏的,漏雨就需要全屋面返工,是极大的浪费;出屋面构筑物如女儿墙、柱子都必须穿过保温层成为大热桥。还因建设近零能耗建筑需对分户隔热限制,当前没有有效限制户间隔热的内间隔墙技术,只好增大楼面保温层厚度,导致增加建筑层高,增加造价,减少建筑层数,增加碳排放,浪费土地。当前的装配式夹芯混凝土剪力墙和框架结构安装的夹芯墙板的内叶和外叶混凝土与中间保温层之间是用纤维增强拉接件连接,拉接件虽然强度高,但直径小,抗弯刚度差,所以中间保温层厚度不能大于100mm,若太厚外叶混凝土下沉超过允许值,保温层厚度薄不满足建设低能耗建筑要求。现在推动装配式建筑预制加工构件采用钢板或铝板的边模板条,成本太高,用螺钉与平台连接还破坏钢平台,增加预制构件成本,影响推动建筑产业化。 2. There are many thermal bridges. Thermal bridges are channels for heat loss. Insulation materials with low thermal conductivity cannot eliminate thermal bridges. Such as window thermal bridge, even if the outer wall insulation layer is infinitely thick, the wall insulation layer around the window can only be about 20mm thick, and the heat will be lost from the wall surrounding the window. External wall attachment thermal bridge, curtain wall decorative steel keel thermal bridge, air conditioner concrete pallet thermal bridge, etc. It is said that the passive houses that have been built in China cannot meet the expected energy-saving targets. This is normal. Who can calculate the heat consumption increased by the above-mentioned thermal bridges? These thermal bridges are like a refrigerator with holes, no matter how thick the refrigerator insulation layer is, it is not good to save energy and keep warm. The increased energy consumption of thermal bridges often exceeds the energy consumption limit specified in the "Near Zero Energy Building Technical Standard" GB/T51350. Because there are a large number of thermal bridges, the insulation layer is thick, the outer wall occupies a lot of land and wastes land, and the cost is high. To build a 90% energy-saving passive house, ordinary EPS panels need to be 400mm thick. Use Harbin Hongsheng’s 800 yuan/m 3 EPS The board needs to be 300mm thick, and long-distance transportation also consumes energy. Thermal bridges make it difficult to promote near-zero energy consumption buildings, especially the thermal bridges of the steel keel for curtain wall decoration! It is very difficult for public buildings to construct energy-saving buildings of 65%, which is a big problem for building energy-saving. There is no bonding between the materials of each layer of the roof, the waterproof durability of the roof is not good, and the roof leaks do not know where the leak is. If the roof leaks, the whole roof needs to be reworked, which is a great waste; the roof structures such as parapets and pillars are all Must pass through the insulation layer to become a large thermal bridge. In addition, because the construction of a near-zero energy consumption building requires thermal insulation for individual households, there is currently no internal partition wall technology that effectively limits the thermal insulation of the households. The thickness of the floor insulation layer has to be increased, which leads to an increase in building height, cost, and number of floors. , Increase carbon emissions and waste land. The current fabricated sandwich concrete shear wall and the sandwich wall panel installed by the frame structure. The inner and outer leaf concrete and the middle insulation layer are connected by fiber-reinforced tie-pieces. Although the tie-pieces have high strength, the diameter Small, poor bending rigidity, so the thickness of the middle insulation layer should not be greater than 100mm. If the outer leaf concrete sinks more than the allowable value if the thickness is too thick, the thickness of the insulation layer is too thin to meet the requirements of building low-energy-consumption buildings. At present, the prefabricated processing components of prefabricated buildings are promoted to use steel or aluminum side template strips. The cost is too high. The connection with screws to the platform also destroys the steel platform, increases the cost of prefabricated components, and affects the promotion of construction industrialization.
以上都是建设节能90%的近零能耗建筑和零能耗建筑、推动建筑产业化的技术障碍,还是一些建筑质量通病难以解决的根本原因。虽然欧洲和中国一些地方政府用高额资金鼓励建设节能90%的被动式节能房,有一定积极作用,但不攻克障碍围护结构节能保温的关键技术,是不可能全面推动建设90%的近零能耗建筑的,用大量资金鼓励建设被动式节能房不能解决根本问题,增加政府财政负担。The above are all technical obstacles to the construction of 90% energy-saving near-zero energy buildings and zero-energy buildings, and to promote the industrialization of buildings. They are also the fundamental reasons why it is difficult to solve some common problems of building quality. Although some local governments in Europe and China have used high funds to encourage the construction of 90% energy-saving passive energy-saving houses, which has certain positive effects, it is impossible to fully promote the construction of 90% energy-saving and thermal insulation without overcoming obstacles. For energy-consuming buildings, using a large amount of funds to encourage the construction of passive energy-saving houses cannot solve the fundamental problem and increase the government's financial burden.
建筑抗震消震及高层建筑抗震抗风、抗侧移是建筑的重要课题。现在多采用增加柱断面,或采用剪力墙结构的以刚克刚方技术,用主体结构的塑性变形来抵抗建筑水平位移和消耗地震能量,结构损伤程度难以控制,地震中损坏的是承重构件甚至房倒屋塌,主体结构塑性变形难以修复,钢材水泥耗量多。Anti-seismic and anti-vibration of buildings, anti-seismic and wind-resistance and anti-side movement of high-rise buildings are important issues of architecture. Nowadays, the technique of increasing the column section or adopting the shear wall structure to overcome the rigid square is adopted. The plastic deformation of the main structure is used to resist the horizontal displacement of the building and consume seismic energy. The degree of structural damage is difficult to control. The load-bearing component is damaged in the earthquake. Even the house collapses, the plastic deformation of the main structure is difficult to repair, and the consumption of steel and cement is high.
当前,人类面临的最大问题是应对全球气候变化,建筑业存在的上述问题直接影响控制全球气候变化,当前建筑技术不适应高科技时代低碳社会的要求。At present, the biggest problem facing mankind is to deal with global climate change. The above-mentioned problems in the construction industry directly affect the control of global climate change. The current construction technology does not meet the requirements of a low-carbon society in the high-tech era.

本发明的技术效果:Technical effects of the present invention:
1、本发明的节能保温墙体技术可彻底杜绝节能保温墙体防火不安全的隐患,具有重要意义。为什么薄抹灰保温墙体防火不好,但仍还在执行薄抹灰保温墙体的技术标准呢?因为认为EPS板强度低不能承受抹灰层重量、不能承受外叶混凝土重量、不能承受外墙附着物重量。EPS板抗拉强度不小于0.1MPa,0.1MPa=1kg/cm 2=10t/m 2,但EPS板弹性模量小呈柔性,必须受力均匀,不能发生局部应力集中。只要胶粘剂品种选用适当、质量合格,混凝土或水泥砂浆或钢板都可与EPS板牢固粘接,耐久性好,成本低,施工方便,安装外墙附着物安全可靠。本发明的建筑技术既解决了节能保温墙体防火安全问题、耐久性差的问题,还把外墙、屋面的热桥都消灭了,减少保温层厚度,节约土地,降低造价,还可在外墙上进行垂直绿化把城市变作森林;而且框架结构的室内间隔墙和外挂墙体还可同时是建筑的阻尼墙,发挥消震减震作用,这都是高科技时代低碳社会需要的建筑技术。 1. The energy-saving insulation wall technology of the present invention can completely eliminate the hidden dangers of unsafe fire protection of the energy-saving insulation wall, which is of great significance. Why is the thin plastered thermal insulation wall not good for fire protection, but the technical standards for the thin plastered thermal insulation wall are still being implemented? It is believed that the EPS board has low strength and cannot bear the weight of the plastering layer, the weight of the outer leaf concrete, and the weight of the external wall attachments. The tensile strength of the EPS board is not less than 0.1MPa, 0.1MPa=1kg/cm 2 =10t/m 2 , but the elastic modulus of the EPS board is small and flexible, and the force must be uniform, and no local stress concentration can occur. As long as the type of adhesive is selected appropriately and the quality is qualified, concrete, cement mortar or steel plate can be firmly bonded to the EPS board, with good durability, low cost, convenient construction, and safe and reliable installation of external wall attachments. The construction technology of the present invention not only solves the problems of fire safety and poor durability of energy-saving insulation walls, but also eliminates thermal bridges on external walls and roofs, reduces the thickness of the insulation layer, saves land, and reduces cost. It can also be installed on external walls. Vertical greening turns the city into a forest; and the indoor partition wall and external wall of the frame structure can also be the damping wall of the building at the same time, playing the role of shock absorption and shock absorption. This is the construction technology required by the low-carbon society in the high-tech era.
2、可全面推动见着近零能耗建筑和全零能耗建筑,使建筑业在应对全球气候变化中发挥重要作用。2. It can comprehensively promote near-zero energy consumption buildings and zero-energy buildings, so that the construction industry can play an important role in responding to global climate change.
本发明的建筑外墙和屋面的节能技术与低传热系数窗户相结合,建筑围护结构满足建筑节能90%要求,可使利用清洁能源建设全零能耗建筑的投资比节能50%~65%的建筑比降低清洁能源投资50%~80%,建设全零能耗建筑就容易了。与已建的被动房比:1)可减少60%~70%的保温层厚度,增加室内使用面积;2)外墙外保温工程降低造价250~300元/m 2,加上不增加楼层分隔采暖可不增加建筑层高降低的造价,比已建的被动式节能房可降低建筑造价约500元/m 2或更多,比节能65%的住宅仅增加造价100~150元/m 2;3)节能保温墙体耐久年限可由25年提高到不少于50年,从可持续发展的角度分析是降低建筑造价。 The energy-saving technology of the building exterior wall and roof of the present invention is combined with low heat transfer coefficient windows, and the building envelope meets the 90% requirement of building energy saving, which can make the investment of building a zero-energy building using clean energy save 50%~65% % Building ratio reduces clean energy investment by 50% to 80%, and it is easy to construct a zero-energy building. Compared with the existing passive house: 1) It can reduce the thickness of the insulation layer by 60% to 70%, and increase the indoor use area; 2) The external wall insulation project reduces the cost by 250-300 yuan/m 2 , and does not increase the floor separation Heating does not increase the cost of building floor height reduction, and can reduce the building cost by about 500 yuan/m 2 or more than the passive energy-saving houses that have been built, and only increase the cost by 100-150 yuan/m 2 compared with the energy-saving houses of 65%; 3) The durability of energy-saving insulation walls can be increased from 25 years to no less than 50 years. From the perspective of sustainable development, the analysis is to reduce the construction cost.
假定中国建筑节能由当前节能50%~65%提高到节能90%(包括既有建筑节能改造),中国建筑能耗将由占社会总能耗30%降低到15%;若绝大部分建筑(包括既有建筑节能改造)建设为全零能耗建筑(采用清洁能源供暖和制冷),建筑能耗将降低到5%~10%,向着建筑能耗不升反降的目标努力,但不包括建材生产制造能耗,即减少社会总能耗约20%,还有难以估量的外墙垂直绿化的作用,建筑业将对控制全球气候变化发挥重要作用。Assuming that China’s building energy efficiency increases from the current 50%-65% energy saving to 90% energy saving (including the energy-saving renovation of existing buildings), China’s building energy consumption will be reduced from 30% to 15% of the total social energy consumption; if most buildings (including The energy-saving renovation of existing buildings will be constructed as a zero-energy building (using clean energy for heating and cooling), the energy consumption of the building will be reduced to 5% to 10%, and efforts will be made towards the goal of building energy consumption instead of rising, but not including building materials Production and manufacturing energy consumption, that is, reducing the total energy consumption of society by about 20%, and the inestimable vertical greening of external walls, the construction industry will play an important role in controlling global climate change.

The window section diagrams in the attached figure all show that there is foaming material in the window profile. There are already such door and window profiles, and the heat transfer coefficient of the window can easily reach 0.8w/ m 2 ·k~1.0w/m 2 ·k, to solve the current problem of high heat transfer coefficient of windows and construction of near zero energy buildings and zero energy buildings.
3、本发明提出框架结构外挂安装层层粘接的轻质混凝土夹芯墙体具有以下意义:3. The present invention proposes that the light-weight concrete sandwich wall bonded layer by layer with the external hanging installation of the frame structure has the following meanings:
轻质混凝土包括轻骨料混凝土、蒸压加气混凝土板、石膏混凝土板及泡沫混凝土,根据强度要求、抗风化、抗冻溶等使用条件应用于不同位置的墙体上。Lightweight concrete includes lightweight aggregate concrete, autoclaved aerated concrete slabs, gypsum concrete slabs and foamed concrete, which are applied to walls in different locations according to the strength requirements, weathering resistance, freeze-thaw resistance and other usage conditions.
1)防火最好,满足各类建筑的防火要求。轻质混凝土导热系数小、热阻大,火灾发生时火焰很难破坏轻质混凝土,可在较长时间内保护内部EPS板不发生受热萎缩,损失小。1) The best fire protection, meeting the fire protection requirements of various buildings. Lightweight concrete has a small thermal conductivity and large thermal resistance. It is difficult for the flame to destroy the lightweight concrete when a fire occurs. It can protect the internal EPS board from shrinking due to heat for a long time, and the loss is small.
2)抗弯高度高,抗弯刚度大,大幅度节约钢材水泥,减少施工中碳排放。2) High bending resistance, high bending rigidity, greatly saving steel and cement, and reducing carbon emissions during construction.
EPS板抗拉强度与承重砌体抗剪切承载力相近,在层层粘接的外挂夹芯混凝土墙板中或夹芯混凝土屋面板中EPS板不仅起到保温绝热作用,还大幅度增加截面抗弯刚度和抗弯高度。根据材料力学理论计算结果是:低标号的LC15轻骨料混凝土夹芯墙板厚250mm时,中间是150mm厚EPS板互相粘接,夹芯墙板抗弯刚度约是普通混凝土楼板2倍或更多,抗弯高度也增加约1倍,但承受的风荷载和地震作用组合值仅是楼板荷载的(1/4~1/2),低标号内外叶混凝土可满足外墙弯曲抗压承载力设计要求,并因刚度大而减少弯曲变形,因抗弯高度高配筋量很少,减少钢材消耗。在层高较高、水平荷载值较大的建筑中,轻质混凝 土夹芯墙体的厚度是结构设计起控制作用,并自然就满足近零能耗建筑对外墙的节能保温要求。The tensile strength of EPS board is similar to the shear resistance of load-bearing masonry. In the layer-by-layer bonded external sandwich concrete wall panel or sandwich concrete roof panel, the EPS board not only plays a role in thermal insulation, but also greatly increases the cross-section Bending stiffness and bending height. The calculation result according to the theory of material mechanics is: when the low-grade LC15 lightweight aggregate concrete sandwich wall is 250mm thick, the middle is 150mm thick EPS slabs bonded to each other, and the flexural rigidity of the sandwich wall is about twice or more than that of ordinary concrete floor slabs. The bending height is also increased by about 1 times, but the combined value of wind load and seismic action is only the floor load (1/4~1/2). The low-grade inner and outer leaf concrete can meet the bending compressive bearing capacity of the outer wall Design requirements, and reduce bending deformation due to large rigidity, because of the high bending height, the amount of reinforcement is small, which reduces the consumption of steel. In buildings with high storeys and large horizontal load values, the thickness of the lightweight concrete sandwich wall is controlled by the structural design, and naturally meets the energy-saving and thermal insulation requirements of the exterior wall of a near-zero energy building.
3)安全性好,地震或大风时外墙不会破坏。轻质混凝土的外挂墙板重量轻,地震作用与重量成正比,即使对外墙按罕遇地震进行荷载组合也远小于风荷载组合值,故可保证地震或大风时外墙安全。3) Good safety, the outer wall will not be damaged during an earthquake or strong wind. The external wall panels of lightweight concrete are light in weight, and the earthquake action is proportional to the weight. Even if the load combination of the external wall according to the rare earthquake is far less than the combined value of the wind load, it can ensure the safety of the external wall during an earthquake or strong wind.
4)墙体厚度最薄,节约土地,可消灭各种热桥,与传热系数0.8w/m 2·k~1.0w/m 2·k的窗户相配合,外挂安装轻质混凝土夹芯墙体厚250mm~300mm,就可满足近零能耗建筑对外墙的节能保温要求,节约土地,室内使用面积大,构造简单、安装简单、重量轻。 4) The thickness of the wall is the thinnest, which saves land and can eliminate various thermal bridges. It is matched with windows with a heat transfer coefficient of 0.8w/m 2 ·k~1.0w/m 2 ·k, and a lightweight concrete sandwich wall is installed externally. With a body thickness of 250mm~300mm, it can meet the energy-saving and thermal insulation requirements of the outer wall of a near-zero energy building, save land, have a large indoor use area, simple structure, simple installation, and light weight.
5)可消耗固体废弃物,轻骨料可用陶粒。陶粒原料有多种,除页岩和粘土外,还可用生活垃圾、污泥、河底泥、粉煤灰作为原料生产陶粒,减轻环境污染,减少消耗砂石。5) Solid waste can be consumed, and ceramsite can be used for light aggregate. There are many kinds of ceramsite raw materials. In addition to shale and clay, domestic garbage, sludge, river bottom mud, and fly ash can also be used as raw materials to produce ceramsite, reducing environmental pollution and reducing the consumption of sand and stone.
6)与装配式混凝土剪力墙夹芯墙体对比,大大减少混凝土量、减少砂石开采量。6) Compared with the prefabricated concrete shear wall sandwich wall, it greatly reduces the amount of concrete and the amount of sand and gravel mining.
剪力墙夹芯墙厚度=内叶混凝土厚约0.25m+外叶混凝土厚0.05m=0.3m,剪力墙混凝土强度高,钢材水泥砂石消耗多,施工阶段碳排放多,不能发挥EPS板的受力性能,是浪费、造价高、外墙厚、重、占地多,且地震导致的墙体破坏基本是不能修复的;而且设计规范规定装配式安装的剪力墙比现浇剪力墙允许建设高度减少10m,即约减少3层,浪费土地,所以本发明不建议选用剪力墙结构。而框架结构安装层层粘接的非承重轻质混凝土夹芯墙体,内外叶混凝土总厚0.1m就满足耐火极限和弯曲抗压受力要求,再加上混凝土柱断面面积约相当于外墙混凝土总厚0.2m,与剪力墙对比减少外墙混凝土量约1/3,外墙轻骨料用陶粒可消耗固体废弃物,与混凝土夹芯剪力墙墙体对比,减少砂石开采量约25~30%,减少钢筋水泥砂石消耗,保护自然资源,减少建设中的碳排放。Shear wall sandwich wall thickness = inner leaf concrete thickness of about 0.25m + outer leaf concrete thickness of 0.05m = 0.3m, shear wall concrete strength is high, steel, cement, sand and gravel consumption are high, carbon emissions during the construction phase are high, and the EPS board cannot be used The mechanical performance is wasteful, high cost, thick and heavy external wall, and large area, and the wall damage caused by earthquake cannot be repaired; and the design code stipulates that the shear wall of prefabricated installation is better than that of cast-in-place shear wall. The allowable construction height is reduced by 10m, that is, approximately 3 floors are reduced, which is a waste of land. Therefore, the present invention does not recommend the selection of a shear wall structure. For the non-load-bearing lightweight concrete sandwich wall with the frame structure installed layer by layer, the total thickness of the inner and outer leaf concrete is 0.1m to meet the fire resistance limit and bending compressive force requirements, and the cross-sectional area of the concrete column is approximately equivalent to that of the outer wall. The total thickness of concrete is 0.2m. Compared with the shear wall, the amount of external wall concrete is reduced by about 1/3. The light aggregate ceramsite used for the external wall can consume solid waste. Compared with the concrete sandwich shear wall, it reduces sand and stone mining. The amount is about 25-30%, reducing the consumption of reinforced cement, sand and gravel, protecting natural resources, and reducing carbon emissions during construction.
4、实施方式八~十的建筑技术是以柔克刚的消能减震建筑技术,其意义是:4. The construction technology of the eighth to tenth embodiments is a soft energy dissipation and shock absorption construction technology, and its significance is:
使建筑由当前以刚克刚为主的抗震技术变为以柔克刚为主的抗震技术,特别是框架结构即使罕遇地震发生时、龙卷风、飓风发生时外墙不会破坏,建筑主体结构可不破坏或破坏轻微便于修复,大幅度降低建筑主体结构造价,安装简单,造价低,适用面广,减少拆除重建和维修、减少建筑垃圾,减少碳排放。Make the building change from the current seismic technology based on rigidity and rigidity to the seismic technology based on flexibility and rigidity. Especially the frame structure will not be damaged even in the rare case of earthquakes, tornadoes, and hurricanes. The main structure of the building may not be damaged or damaged. Slight damage is easy to repair, greatly reducing the cost of the main structure of the building, simple installation, low cost, wide application, reducing demolition, reconstruction and maintenance, reducing construction waste, and reducing carbon emissions.
2)实施方式九的室内夹芯保温间隔阻尼墙既有阻尼作用,同时又解决了近零能耗建筑对分户采暖隔热要求的难题,缓解对楼层隔热保温增加建筑层高的难题,建设近零能耗建筑可不因隔热要求增加建筑层高,既降低造价又节约土地。实施方式十的各种外挂墙体有阻尼作用,与室内间隔墙的阻尼墙配合可有效地减少建筑、特别是高层建筑在水平荷载的作用下的位移,安装简单。2) The indoor sandwich thermal insulation partition damping wall of the ninth embodiment not only has a damping effect, but also solves the problem of heating and insulation requirements for households in a near zero energy building, and alleviates the problem of increasing the building height for floor insulation. The construction of a building with near zero energy consumption does not increase the height of the building due to thermal insulation requirements, which reduces the cost and saves land. The various external wall bodies of the tenth embodiment have a damping effect, and the cooperation with the damping wall of the indoor partition wall can effectively reduce the displacement of the building, especially the high-rise building, under the action of horizontal load, and the installation is simple.
3)实施方式八在基础与地基之间安装弹性体材料,地震发生时从建筑底部就大幅度减少地震作用对上部结构的影响,高地震烈度区的建筑可考虑采用;非抗震设防地区或抗震设防较低地区的建筑,若风荷载组合值较大,建议主要采用实施方式九和十的以柔克刚技术,减少建筑侧移;若位于地震烈度较高地区,同时又是风荷载组合值较大的建筑,建议将实施方式八~十配合应用。3) The eighth embodiment is to install elastomer materials between the foundation and the foundation. When an earthquake occurs, the impact of the seismic action on the superstructure will be greatly reduced from the bottom of the building. Buildings in areas with high seismic intensity can be considered; non-seismic fortified areas or earthquake-resistant For buildings in areas with lower fortifications, if the combined value of wind load is large, it is recommended to mainly adopt the soft-relief technology of
4、本发明之所以提出多种节能保温墙体和屋面技术,还提出不同的消能减震筑技术,是希望通过对比不同建筑技术供工程择优选择、配合应用,在选择建筑结构体系时既考虑使设计的墙体具有全面优点,又有利于建筑消能减震。本发明推荐:4. The reason why the present invention proposes a variety of energy-saving insulation wall and roof technologies, and also proposes different energy dissipation and vibration reduction construction technologies, is to compare different building technologies for engineering selection and application. It is considered that the designed wall has all-round advantages, and it is also conducive to building energy dissipation and shock absorption. The present invention recommends:
1)推荐新建工程设计为框架结构或框架-核心筒结构,室内间隔墙或分户间隔墙安装为阻尼墙,外墙安装具有前述全面优点的轻质混凝土夹芯外挂墙体,消灭各种热桥建设近零能耗建筑。这既保证建筑主体结构和外墙抗震、抗风安全,又容易建设近零能耗建筑和零能耗建筑,墙体厚度薄,节约土地,防火安全,耐久性好,降低建筑主体结构造价,大幅度减少钢材、水泥、砂石消耗,减少建设阶段碳排放,并告别落后的建筑安装方式,全面推动建筑产业化,使建筑产业升级换代。1) It is recommended that the new construction is designed as a frame structure or a frame-core tube structure. The indoor partition wall or household partition wall is installed as a damping wall. The external wall is installed with a lightweight concrete sandwich wall with the aforementioned comprehensive advantages to eliminate all kinds of heat. Bridge construction is near zero energy consumption building. This not only guarantees the safety of the main structure of the building and the outer wall against earthquakes and wind, but also makes it easy to construct near-zero energy buildings and zero-energy buildings. The wall thickness is thin, land saving, fire safety, and durability are good, and the cost of the main structure of the building is reduced. Significantly reduce the consumption of steel, cement, sand and gravel, reduce carbon emissions during the construction phase, and bid farewell to outdated construction and installation methods, comprehensively promote the industrialization of construction, and upgrade the construction industry.
根据建筑使用功能、建筑规模、平面和空间布局、地震烈度、水平风压,确定采用实施方式八~十中哪一种消震减震、减少建筑水平位移的建筑技术,或可不考虑建筑抗震抗风仅满足建筑节能要求固定式安装外挂墙板;既有框架结构可拆除原砌体墙采用本建议。例如,对计算建筑位移较大一侧的墙体采用实施方式九和十的阻尼间隔墙和阻尼外挂墙板的消能减震、抗侧移建筑技术,对计算位移较小一侧的墙体可以固定式安装外挂墙板,固定式安装外挂墙板的安装方法是:找好建筑的外墙垂直度以后,可以用射钉型塑料锚栓将外挂墙板与梁柱或梁柱上安装的找平钢件固定,并用结构胶或水泥聚合物砂浆将外挂墙板与梁柱粘贴,还可再在梁柱外侧的外挂墙板与梁柱之间的较大缝隙处粘贴EPS板填塞缝隙,并在EPS板周边应安装防火材料满足防火要求。According to the building use function, building scale, plane and space layout, earthquake intensity, horizontal wind pressure, determine which of the eight to ten implementation methods to reduce the vibration and reduce the horizontal displacement of the building technology, or not consider the seismic resistance of the building The wind only meets the requirements of building energy saving for fixed installation of external wall panels; this recommendation is adopted for existing frame structures that can be removed from the original masonry wall. For example, the damping partition wall and the damping external wall panel of the
2)本发明不推荐框架结构建筑采用实施方式十一的安装抗侧移斜撑以刚克刚的建筑抗震抗侧移技术,安装抗侧移斜撑技术适用于既有的承重墙体建筑抗震加固并同时进行建筑节能改造。2) The present invention does not recommend the use of the eleventh embodiment for the installation of anti-side movement diagonal bracing and the rigid building anti-side movement technology for frame structure buildings. The installation of anti-side movement diagonal bracing technology is suitable for existing load-bearing wall buildings. Reinforce and carry out building energy-saving renovation at the same time.
3)推荐既有建筑的承重墙节能改造工程采用实施方式一构造,选用不同厚度的竖丝岩棉板满足不同 防火等级要求,安装简单,满足任意装饰。在安装EPS板过程中应及时安装不燃保温材料,使施工过程中EPS板发生火灾的机会几乎为零。3) It is recommended that the load-bearing wall energy-saving renovation projects of existing buildings adopt the construction of
不方便购买竖丝岩棉板地区的建筑推荐采用实施方式二,一旦失火虽然EPS板会较快遇热萎缩,但外部水泥砂浆保护层被BFRP布包裹不能脱落,EPS板难以接触明火火灾难以蔓延。灾后维修钻孔穿过水泥砂浆保护层,注入聚氨酯发泡保温,聚氨酯发泡可与EPS板和水泥砂浆层粘接,维修简单。It is recommended to adopt

5、框架结构在采用本发明的墙体技术时应用有限元软件分析墙体内力5. When the frame structure adopts the wall technology of the present invention, the finite element software is used to analyze the internal force of the wall
有限元软件是基础工业软件,已经诞生多年,用有限元软件可分析建筑各个部位的内力,再根据力学和混凝土结构理论配筋,如前述,内外叶是轻质混凝土的外挂墙板地震或大风时外墙不会破坏。但现在建筑业不要求用有限元软件分析框架结构的砌块填充墙内力,因为在风力较大地区或地震烈度较大地区,砌块填充墙不可能满足计算软件计算出的数据要求,是导致地震和大风时非承重墙体破坏的根本原因。如对某工程非承重墙用有限元软件分析内力,在风荷载作用下,窗间墙侧壁弯矩是无洞口墙体弯矩的5~6倍,窗间墙角部剪力是无洞口墙体剪力10多倍甚至有达30多倍。Finite element software is a basic industrial software. It has been born for many years. The finite element software can analyze the internal forces of various parts of the building, and then reinforce the reinforcement according to the mechanics and concrete structure theory. As mentioned above, the inner and outer leaves are light-weight concrete external wall panels. When the exterior wall will not be destroyed. But now the construction industry does not require the use of finite element software to analyze the internal force of the block-filled wall of the frame structure, because in areas with high wind or seismic intensity, the block-filled wall cannot meet the data requirements calculated by the calculation software. The root cause of non-load-bearing wall damage during earthquakes and strong winds. For example, using finite element software to analyze the internal force of a non-load-bearing wall of a project, under the action of wind load, the bending moment of the side wall of the window wall is 5-6 times that of the wall without opening, and the shear force at the corner of the window wall is the wall without opening. The body shear force is more than 10 times or even more than 30 times.
6、本发明在外墙和窗口侧边粘贴BFRP布有以下多方面作用:6. Pasting BFRP cloth on the sides of exterior walls and windows of the present invention has the following functions:
1)BFRP布导热系数为0.035~0.04w/m·k,将BFRP布安装在门窗口周边不增加传热,安装BFRP布是消灭门窗口周边墙体热桥、消灭遮阳卷帘热桥、消灭防盗栅栏热桥、消灭外挂空调机托板热桥,推动建设近零能耗建筑的必要条件之一。不安装BFRP布就不能把窗户离开基层墙体移到靠近窗口外角约50mm处安装,不能使室外冷点距离窗口周边墙体的热阻不小于主墙体热阻,就不能消灭窗口墙体周边热桥,不能消灭安装窗口周边其它外墙附着物热桥。2)BFRP布具有极高的抗拉强度,是钢材的十倍到十几倍,例如某厂家提供面密度300g/m 2的普通BFRP布,根据国检报告数据折算成每米数据,其经纬向最小抗拉强力标准值达7.2t/m,考虑安全系数为2,抗拉强力设计值为3.6t/m。选择满足强度要求的BFRP布或增加粘贴BFRP布的层数。门窗口侧面粘贴的BFRP布的水平纤维是门窗口的水平拉接钢筋,即抗剪切钢箍,可保证与门窗口外角安装的L形预埋钢板锚固安装的窗户、遮阳卷帘、防盗栅栏的安全;还可避免非承重墙体在风力作用下对窗间墙角部墙体的撕扯(剪切)破坏;BFRP布还是沿建筑周圈的钢箍,在地震或大风時外墙摆动可增加外墙安全(高层建筑摆动尤其突出),增加外墙抵抗震灾风灾能力,例如经常发生龙卷风、飓风、台风的地区,只要主体结构的柱子和基础与地基锚固牢固,木板墙都难以破坏。3)BFRP布是绿色纤维,价格低,可大幅度提高外墙耐久性。在外墙保温层EPS板上粘贴不燃保温材料,在不燃保温材料上粘贴BFRP布可保护不燃保温材料,且胶粘剂就是防水材料,增加不燃保温材料使用年限,彻底解决外墙开裂进水的质量通病;BFRP布与其它满足耐久年限不少于50年的材料配合,节能保温墙体耐久年限可由25年提高到不低于50年,维修量小,符合建筑全寿命期可持续发展原则。4)外墙上粘贴BFRP布可增加安装外墙附着物的安全,容易在外墙上垂直绿化,外墙垂直绿化不需沿建筑周圈搭设钢架,没有钢架防腐维修的复杂问题,不占用土地,减小外墙垂直绿化难度。外墙垂直绿化使城市变作森林,缓解夏季热岛效应,减少雾霾、调节城市湿度、制造氧气、改善空气质量、消音隔尘、改善城市面貌,减少夏季空调用电,外墙垂直绿化对控制全球气候变化的作用难以估量。5)安装BFRP布可解决装配式墙体的预制墙板接缝密封保温不好难题,消灭接缝热桥。6)在BFRP布内有预埋钢板,安装窗户时不需要安装副框,可消灭窗户副框热桥,还大大降低窗户工程造价,作用大。 1) The thermal conductivity of BFRP cloth is 0.035~0.04w/m·k. Installing BFRP cloth around doors and windows does not increase heat transfer. Installing BFRP cloth eliminates the thermal bridges of the walls around the doors and windows, and eliminates the thermal bridges of the sunshade and roller shutters. The anti-theft fence thermal bridge and the elimination of the external air conditioner pallet thermal bridge are one of the necessary conditions for promoting the construction of near-zero energy consumption buildings. Without installing BFRP cloth, you cannot move the window away from the base wall and install it near the outer corner of the window about 50mm. The thermal resistance of the outdoor cold spot from the wall surrounding the window cannot be less than the thermal resistance of the main wall, and the surrounding window wall cannot be eliminated. The thermal bridge cannot eliminate the thermal bridge of other external wall attachments around the installation window. 2) BFRP cloth has a very high tensile strength, steel is ten times to ten times, for example, a factory to provide general BFRP cloth surface density 300g / m 2, and converted into data according to the seizure per meter report data, warp and weft The minimum tensile strength standard value is 7.2t/m, considering the safety factor of 2, the tensile strength design value is 3.6t/m. Choose BFRP cloth that meets the strength requirements or increase the number of layers of BFRP cloth. The horizontal fiber of the BFRP cloth pasted on the side of the door and window is the horizontal drawbar of the door and window, that is, the shear-resistant steel hoops, which can ensure that the L-shaped embedded steel plate installed at the outer corner of the door and window is anchored to the installed windows, sunshade shutters, and anti-theft fence It can also prevent the non-load-bearing wall from tearing (shearing) the wall at the corner of the window under the action of the wind; the BFRP cloth is still a steel hoop along the building's circumference, which can increase the swing of the outer wall during an earthquake or strong wind The outer wall is safe (high-rise buildings swing particularly prominent), and the outer wall is more resistant to earthquake disasters. For example, in areas where tornadoes, hurricanes, and typhoons often occur, as long as the pillars and foundations of the main structure are firmly anchored to the foundation, the wooden wall is difficult to damage. 3) BFRP cloth is a green fiber with low price, which can greatly improve the durability of exterior walls. Paste non-combustible thermal insulation material on the EPS board of the external wall insulation layer, and paste BFRP cloth on the non-combustible thermal insulation material to protect the non-combustible thermal insulation material, and the adhesive is a waterproof material, which increases the service life of non-combustible thermal insulation materials and completely solves the common quality problems of external wall cracking and ingress of water; BFRP cloth is matched with other materials that have a durability life of no less than 50 years. The durability of energy-saving insulation walls can be increased from 25 years to no less than 50 years. The amount of maintenance is small, and it is in line with the principle of sustainable development throughout the life of the building. 4) Pasting BFRP cloth on the external wall can increase the safety of installing external wall attachments, and it is easy to vertically green the external wall. The vertical greening of the external wall does not require a steel frame along the building circumference, and there is no complicated problem of steel frame anti-corrosion maintenance, and it is not occupied. Land, reducing the difficulty of vertical greening of external walls. The vertical greening of the outer wall turns the city into a forest, alleviating the summer heat island effect, reducing haze, adjusting the urban humidity, producing oxygen, improving air quality, silencing and isolating dust, improving the appearance of the city, reducing electricity consumption for air conditioning in summer, and controlling the vertical greening of the outer wall The impact of global climate change is incalculable. 5) The installation of BFRP cloth can solve the problem of poor sealing and heat preservation of the prefabricated wall panels of the fabricated wall, and eliminate the thermal bridge of the joints. 6) There are pre-embedded steel plates in the BFRP cloth, and there is no need to install the auxiliary frame when installing the window, which can eliminate the thermal bridge of the auxiliary frame of the window, and greatly reduce the construction cost of the window, which has a great effect.
7、本发明解决了困扰建筑业头痛的胶粘剂问题,可保证预埋钢板与EPS板粘接可靠,可保证粘贴安装保温层可靠,可保证节能保温墙体和屋面各层层层粘接可靠。7. The present invention solves the adhesive problem that plagues the construction industry, can ensure the reliable bonding of the embedded steel plate and the EPS board, can ensure the reliable bonding and installation of the thermal insulation layer, and can ensure the reliable bonding of the energy-saving thermal insulation wall and the roof.

Wind-resistant technology and building technology that are unified with the industrialization of buildings can not only promote the construction of near-zero energy buildings and zero-energy buildings, greatly save land, facilitate construction, reduce cost, promote assembly installation, and increase building durability. , Which greatly reduces the carbon emissions of buildings during construction and long-term use, and is also a construction technology that is flexible to overcome rigidity, energy dissipation and shock absorption to ensure the safety of buildings against earthquakes and wind.
高科技低碳社会的建筑技术在应对全球气候变化中将发挥重要作用。The construction technology of a high-tech and low-carbon society will play an important role in coping with global climate change.

本发明与已公开技术的不同点在于:The difference between the present invention and the disclosed technology is:
1、从来没有本发明实施方式一和二的节能保温墙体的防火构造,这是全球没有解决的难题。1. There has never been a fire protection structure for the energy-saving insulation wall of the first and second embodiments of the present invention, which is an unsolved problem in the world.
2、从来没有实施方式三用低强度廉价材料作为预制混凝土构件的边模板条的建筑技术。2. There has never been a construction technology that uses low-strength and inexpensive materials as the side formwork strips of precast concrete components in the third embodiment.
3、从来没有实施方式四和五用蒸压加气混凝土板或石膏混凝土板与保温层粘接的预制混凝土夹芯板,使蒸压加气混凝土板或石膏混凝土板在建筑节能中的应用受到限制。3. The fourth and fifth implementations have never used autoclaved aerated concrete slabs or gypsum concrete slabs to bond the precast concrete sandwich panels with the insulation layer, so that the application of autoclaved aerated concrete slabs or gypsum concrete slabs in building energy conservation is greatly affected. limit.
4、在建筑上用环氧树脂胶粘剂或其它非水溶性胶粘剂将保温板与基层粘贴及将预埋钢板或抗侧移斜撑与保温板粘贴是一种新思路,是从来没有的,不是显而易见的,因为人们容易被既有的观念和知识限制,使得长期以来难以解决的粘贴可靠性难题得以解决。4. It is a new idea to use epoxy resin adhesive or other non-water-soluble adhesives to paste the insulation board to the base layer and to paste the embedded steel plate or the anti-side movement diagonal brace with the insulation board in the building. Yes, because people are easily restricted by existing concepts and knowledge, so that the long-term difficult to solve the problem of reliability of paste can be solved.
2020年3月26日报道“18层的高层住宅怎么建造成被动房?”,文中说外墙粘苯板每层设置结构性托架承托保温板,但是托架不能解决大风负风压时风的吸力把保温板拉下来,只有把保温板牢固地粘贴到基层墙体上才是解决问题的根本办法。可用环氧树脂胶粘剂将EPS板或XPS板与基层粘贴,环氧树脂胶粘剂粘接速度快,用环氧树脂结构胶(可加入净砂)粘贴达到胶粘剂最大强度的1/20~1/30就能满足使用抗拉强度使用要求,只需2~3h(气温越高粘接速度越快),加快施工进度,降低施工成本。而用水泥聚合 物砂浆粘贴需要不小于24h达到粘接强度,施工慢,成本高。It was reported on March 26, 2020, "How can an 18-story high-rise residential building be built into a passive house?" The article said that the external wall styrene board is equipped with structural brackets to support the insulation board on each layer, but the brackets cannot solve the negative wind pressure of the strong wind. The suction force of the wind pulls the insulation board down, and only sticking the insulation board firmly to the base wall is the fundamental solution to the problem. The EPS board or XPS board can be pasted with the base layer with epoxy resin adhesive. The bonding speed of epoxy resin adhesive is fast. It can be pasted with epoxy resin structural adhesive (clean sand can be added) to reach 1/20~1/30 of the maximum strength of the adhesive. It can meet the requirements of using tensile strength and only needs 2 to 3 hours (the higher the temperature, the faster the bonding speed), which speeds up the construction progress and reduces the construction cost. However, it takes no less than 24 hours to reach the bonding strength with cement polymer mortar, which is slow in construction and high in cost.
消灭安装外墙附着物热桥的隔热断桥构造是在解决了困扰建筑业头痛的胶粘剂问题的基础上提出来的,只有用环氧树脂胶粘剂粘接才能确保在EPS板上粘贴预埋钢板安装外墙附着物的可靠性,才能解决障碍建设近零能耗建筑的热桥难题,可彻底解决外保温墙体保温板脱落事故层出不穷的问题。The thermal insulation broken bridge structure that eliminates the thermal bridge installation of external wall attachments is proposed on the basis of solving the adhesive problem that plagues the construction industry. Only by bonding with epoxy resin can the embedded steel plate be adhered to the EPS board. The reliability of the installation of external wall attachments can solve the problem of thermal bridges that impede the construction of near-zero energy consumption buildings, and can completely solve the endless problem of accidents of external insulation wall insulation panels falling off.
且现在钢件的防腐都是在使用前进行防腐的,从来没有提出用胶粘剂解决钢件防腐难题,由此减少钢件防腐加工难度,且施工方便,防腐效果好。Moreover, the anti-corrosion of steel parts is carried out before use. The use of adhesives to solve the problem of anti-corrosion of steel parts has never been proposed, thereby reducing the difficulty of steel parts anti-corrosion processing, and the construction is convenient, and the anti-corrosion effect is good.
5、从来没有本发明的各种抗震消震、抗侧移的建筑技术。5. There has never been a variety of anti-seismic, anti-vibration, and anti-side movement building technologies of the present invention.
6、从来没有本发明的各种节能保温墙体和屋面的施工安装工法和预制加工工法。6. There has never been a variety of energy-saving insulation wall and roof construction and installation methods and prefabrication methods of the present invention.
墙体节能保温工程除存在防火不好的严重问题以外,还存在太多质量通病:开裂进水、耐久性差、屋面防水耐久性差等,建筑质量通病的实质是对某些技术问题没有搞清楚。中国有太多的人全力研究不燃保温材料多年,事实证明,在墙体技术中无机保温材料仅能在有限的范围内替代有机保温材料,用无机保温材料难以建设近零能耗建筑,而且再高级的保温材料也不能消灭热桥。任何一种材料都有其优缺点,墙体技术是一种技术体系,不是某一个专业、某一种材料就能把所有问题都解决的。背景技术所述事关节能保温墙体防火安全、事关节能保温墙体结构安全、事关消灭热桥建设近零能耗建筑、事关建筑抗震抗风、事关建筑质量通病的诸多问题只有通过跨学科(力学和建筑结构、建筑节能、建筑物理、建筑热工、建筑施工、建筑防水、建筑材料等)、跨领域(化工领域的胶粘剂、弹性体材料、发泡橡胶、发泡塑料)等知识的支撑,合理利用各种材料(如BFRP布、各种胶粘剂、弹性体材料、各种防火材料等),发挥不同材料优点避免其缺点,优化外墙和屋面构造,才能解决建筑技术长期难以解决的诸多问题。本发明是本专利申请人在长达19年多时间进行跨专业、跨领域的学习研究成果,本发明是从来没有的,也不是显而易见的。In addition to the serious problems of poor fire protection, wall energy-saving and thermal insulation projects also have too many common quality problems: cracking and water ingress, poor durability, poor roof waterproof durability, etc. The essence of common building quality problems is that some technical problems are not clear. There are too many people in China who have studied non-combustible thermal insulation materials for many years. Facts have proved that inorganic thermal insulation materials can only replace organic thermal insulation materials in a limited range in wall technology. It is difficult to construct buildings with nearly zero energy consumption with inorganic thermal insulation materials. Advanced insulation materials cannot eliminate thermal bridges. Any kind of material has its advantages and disadvantages. Wall technology is a technical system, and not a certain profession or a certain material can solve all the problems. BACKGROUND OF THE INVENTION The only issues that are related to the fire safety of joint energy-insulating walls, the safety of joint-energy-insulating wall structures, the elimination of thermal bridges, the construction of near-zero energy consumption buildings, the earthquake resistance and wind resistance of buildings, and the common problems of building quality are only Through interdisciplinary (mechanics and building structure, building energy efficiency, building physics, building thermal engineering, building construction, building waterproofing, building materials, etc.), interdisciplinary (adhesives, elastomer materials, foamed rubber, foamed plastics in the chemical industry) With the support of other knowledge, rational use of various materials (such as BFRP cloth, various adhesives, elastomer materials, various fireproof materials, etc.), the advantages of different materials to avoid their shortcomings, and the optimization of exterior wall and roof structure can solve the long-term construction technology. Many problems that are difficult to solve. The present invention is the result of cross-professional and cross-field study and research conducted by the patent applicant for more than 19 years. The present invention has never been seen before and is not obvious.

The construction technology of this embodiment is a low-carbon society in the high-tech era. It is an energy-saving insulation wall fire protection technology.
《建筑设计防火规范》GB50016中6.7.3条规定,夹芯保温墙体的有机保温层二侧采用厚度不小于50mm的不燃材料,并满足耐火极限要求,可满足各类建筑防火要求。本实施方式的不燃保温材料厚50mm时符合此规定;不燃保温材料厚20mm时,可替代现在薄抹灰保温墙体3~5mm薄抹灰保护层,提高防火安全。Article 6.7.3 of the "Code for Fire Protection Design of Buildings" GB50016 stipulates that the two sides of the organic insulation layer of the sandwich insulation wall adopt non-combustible materials with a thickness of not less than 50mm, and meet the fire resistance requirements, which can meet the fire protection requirements of various buildings. When the thickness of the non-combustible thermal insulation material of this embodiment is 50 mm, it meets this requirement; when the thickness of the non-combustible thermal insulation material is 20 mm, it can replace the current 3 to 5 mm thin plastering protective layer of the thin plastering thermal insulation wall to improve fire safety.
进一步地,它还增加预埋钢板4和和高强耐久纤维布3,所述有机保温层2是EPS板,或所述有机保温层2采用其它保温材料时,需经试验证明在长期使用中具有适应变形的能力,粘接界面不破坏,耐久性满足要求;所述高强耐久纤维布是玄武岩纤维布,简称BFRP布,或是可替代BFRP布的其它纤维布;所述预埋钢板4包括室外门窗转角L形预埋钢板4-1和外墙其余位置安装的预埋钢板4-2,在室外门窗转角安装L形预埋钢板4-1是为了安装窗户时,安装窗户的连接铁件与L形预埋钢板4-1固定,保证安装窗户的安全,且安装窗口外遮阳卷帘、安装预制的室外窗台板、安装窗口周边装饰线条都需要与L形预埋钢板4-1固定;外墙其余位置安装的预埋钢板4-2对应于外墙上需要安装外墙附着物的位置,在安装较重外墙附着物位置处EPS板与基层墙体或内叶混凝土1粘接为宜(例如隔热断桥安装空调机托板处、安装用于外墙上人检修的预埋钢板处、安装广告牌处),用胶粘剂将预埋钢板4与EPS板粘接连接及与窗口周边保温层粘接;所述预埋钢板4与EPS板之间粘接面积发生的抗拉承载力,应不小于安装外墙附着物的重量和负风压荷载组合值对预埋钢板4的拉拔力,并有一定安全储备,如安全系数为2,由专家合议确定;用胶粘剂将BFRP布3粘贴到不燃保温材料9表面,还粘贴到门窗口侧面与门窗口侧面的不燃保温材料9粘贴,及与内侧基层墙体1贴粘,还粘贴到变形缝侧面;或还用塑料锚栓穿过BFRP布3、不燃保温材料9、有机保温层2与基层墙体1固定(BFRP布外面是涂料装饰时,为防止不燃保温材料9吸水冻融粉化脱落,安装塑料锚栓有助于不燃保温材料长期使用中受水浸冻融粉化难以脱落);BFRP布与门窗口侧边基层墙体粘贴宽度不小于规定值如150mm,且不小于设计计算窗口侧边承受的剪切力作用到BFRP布上时,BFRP布所需要的抗拉承载力,若BFRP布自身抗拉强度设计值不满足抗剪切承载力时,应增加粘贴的BFRP布层数,应有一定安全储备,粘贴范围应符合设计规定。Further, it also adds embedded
在BFRP布3外侧可任意装饰,如涂料、粘贴饰面砖或安装幕墙装饰板。The outside of
EPS板各向同性,受力性能稳定,而目前所知各种不燃保温材料9的力学性能多不稳定,易受潮、易冻融粉化,竖丝岩棉板虽然垂直于外墙方向的抗拉强度与EPS板接近,但各向不同性(在平行于外墙平面几乎没有抗拉强度),且一旦受潮抗拉强度下降,因此应将外墙除窗口以外位置安装的预埋钢板4-2与EPS板粘接,不宜将预埋钢板4-2与不燃保温材料9粘接,除非外饰面可保证竖丝岩棉板不受潮,且在风荷载和地震作用下外饰面没有平行于外墙的水平位移;但在室外门窗口转角处安装L形预埋钢板4-1可与不燃保温材料9粘接,因为转角处有BFRP布从门窗口正立面转90度粘贴到窗口侧面,并与室内基层墙体1粘接,仅仅依靠BFRP布的抗拉承载力,就满足将门窗、遮阳卷帘、防盗栅栏与预埋钢板4-1连接固定的安全,所以L形预埋钢板4-1可与外墙窗口转角的不燃保温材料9粘贴,但是外墙其余位置安装的预埋钢 板4-2与EPS板粘接安全性更好。The EPS board is isotropic and has stable mechanical properties. However, the mechanical properties of various non-combustible

For example, a 50mm thick vertical wire rock wool board (the rock wool wire is perpendicular to the side wall of the window) is installed as a fire barrier for the door and window; the door window is For the passage of flames, it is recommended to install non-combustible thermal insulation materials on the surrounding insulation layer of building doors and windows regardless of the fire rating;

3)窗户安装后,在窗口室内侧边粘贴的BFRP布3上涂刷胶粘剂抹保温砂浆16或安装其它不燃保温材料(如竖丝岩棉板),保温砂浆16表面用抹水泥压光;如保温砂浆是导热系数不大于0.1w/m·k的珍珠岩砂浆等,一旦失火热量不容易穿透保温砂浆等破坏粘贴BFRP布3的高分子胶粘剂,减小火灾损失,且增加窗口周边基层墙体热阻,进一步减小窗口周边基层墙体热桥;3) After the window is installed, apply adhesive to the
4)还可在预埋钢板4上粘贴隔热材料,如粘贴一定厚度BFRP布,增加预埋钢板隔热性能。4) It is also possible to paste thermal insulation materials on the embedded
本实施方式通过在外墙外保温的有机保温层外侧粘贴不燃保温材料,根据不燃保温材料厚度不同满足不同等级的防火安全要求,且在不燃保温材料9上粘贴高强耐久的BFRP布为保护层,BFRP布保护层不会开裂,其耐久性几乎是无限的;且粘贴BFRP布的胶粘剂就是防水材料,故节能保温墙体防火好、防水好、耐久性好。本实施方式还将预埋钢板粘贴在EPS板上,发挥EPS板抗拉强度,消灭安装外墙附着物的连接铁件热桥,并同时保证防火安全性。In this embodiment, a non-combustible thermal insulation material is pasted on the outside of the organic thermal insulation layer of the external wall to meet different levels of fire safety requirements according to the thickness of the non-combustible thermal insulation material, and a high-strength and durable BFRP cloth is pasted on the non-combustible

The installation of BFRP cloth can be wound horizontally for each layer. A roll of BFRP cloth is inserted into the pole of a movable base, and the BFRP cloth is released with the rotation of the BFRP cloth, so that the joints are minimal); the horizontal joints should be located at the center line of the beam (including the ring beam) or enter the beam The length of the support should not be less than a certain range, if it is not less than 100mm, it is advisable (artificial regulations, not absolute). The horizontal joints should not be located on the wall of non-load-bearing windows without columns, otherwise, they need to meet the strength requirements after lap and paste. The BFRP cloth of the upper layer at the joint should be pressed and pasted on the BFRP cloth of the next layer;
b、垂直安装:一次安装的BFRP布应尽量长,减少水平接缝,应符合前述水平接缝的规定;BFRP布的水平接缝位于窗槛墙处为宜,BFRP布的垂直接缝不宜位于窗间墙上距离门窗口侧边规定的较小范围内,如200mm以内(不是绝对的,根据有限元软件对外墙的内力分析结果确定);BFRP布在门窗洞口内的宽度应满足将BFRP布粘贴到窗间墙侧边与基层墙体的粘贴宽度,不宜在窗间墙侧边再将BFRP布加宽与室内基层墙体1粘贴,否则需满足搭接粘贴等强度要求:将BFRP布缠绕在塑料粗管上,从上往下逐渐放下垂直展开,将BFRP布粘贴安装到不燃保温材料上;b.

说明:安装BFRP布满足窗间墙侧边抗剪切承载力有二个条件:Note: There are two conditions for installing BFRP cloth to meet the shear resistance of the side wall between the windows:
1,BFRP布与窗间墙侧边基层墙体粘贴宽度范围内的平行抗拉承载力应满足要求;1. The parallel tensile bearing capacity within the pasting width of the BFRP cloth and the side base wall of the wall between the windows shall meet the requirements;
2,BFRP布自身的抗拉强力满足要求。因建筑的柱距远大于层高,对某工程的外墙用有限元软件分析证明:窗间墙侧边角部剪切力最大,门窗口侧边中部剪切力为“0”呈三角形分布,故在BFRP布抗拉强度不满足要求时,应在窗间墙角部局部增加粘贴BFRP布的层数,BFRP布与基层墙体粘贴宽度应不小于规定值。2. The tensile strength of BFRP cloth itself meets the requirements. Because the column distance of the building is much larger than the storey height, the finite element software analysis of the external wall of a certain project proves that the shear force at the side corners of the wall between the windows is the largest, and the shear force at the middle of the side of the door and window is "0", which is triangularly distributed. Therefore, when the tensile strength of BFRP cloth does not meet the requirements, the number of layers of BFRP cloth should be added locally at the corners of the windows between the windows, and the width of the BFRP cloth and the base wall should not be less than the specified value.

The bonding between the plastering layers is firm, and the plastering surface should be painted into a straight but not bright, fine brown eye shape. When the rough surface is formed with a wooden trowel and there are sizing on the surface, immediately use a steel trowel to wipe and press. The sizing and the exposed sand particles are overwhelmed and smoothed to make the surface of the mortar look like a fine brown eye. The plastering surface is smoothed with a 2m scraper, and the lines are straight and square, which should meet the requirements of industry standards for the flatness and verticality of the external wall surface; proceed first; Small-area cement mortar plastering construction (commonly known as model wall), followed by large-area plastering construction; the front and rear cement mortar plastering joints should be painted with interface agent or plain slurry to avoid cracks in the plastering at the joints;

The cracks are within the allowable range:
a、在预拌的水泥砂浆和混凝土内有阻裂纤维,阻裂纤维的掺量按厂家说明书并试验确定,注意不应使用柳絮状聚丙烯短切纤维,阻裂效果不好;用搅拌机将阻裂纤维打散与水泥砂浆或与混凝土充分混合,或在水泥砂浆或混凝土内还可加入可起增稠保水作用的材料如纤维素醚MC等;例如阻裂纤维为聚丙烯短切纤维或其它阻裂纤维,加入质量较好的聚丙烯短切纤维,即使在较高气温(约35℃)时,水泥砂浆上墙后约二天内也可以有效地减缓水泥砂浆出现干燥、开裂、失水粉化破坏,或还加上覆膜养生更好(屋面很方便覆膜养生);聚丙烯短切纤维是各种阻裂纤维中价格最低的,在水泥砂浆和混凝土硬化初期对阻裂可起到重要作用,但后期聚丙烯短切纤维将消失,在安装BFRP布的外墙上只要在水泥砂浆硬化初期有聚丙烯短切纤维阻裂即可,当然可以用更高级、耐久性更好的阻裂纤维,譬如选用纤维素纤维;a. There are crack-resisting fibers in the ready-mixed cement mortar and concrete. The amount of the crack-resisting fibers is determined according to the manufacturer’s instructions and tested. Note that the catkin-like polypropylene chopped fibers should not be used because the crack resistance is not good; The crack-resisting fiber is dispersed and fully mixed with cement mortar or concrete, or a material that can thicken and retain water, such as cellulose ether MC, can be added to the cement mortar or concrete; for example, the crack-resisting fiber is polypropylene chopped fiber or Other crack-resistant fibers, adding good quality polypropylene chopped fibers, even at higher temperatures (about 35℃), the cement mortar can effectively slow down the drying, cracking, and loss of water within about two days after the cement mortar is applied to the wall. Powdered damage, or even better with film coating (roofing is very convenient for film curing); polypropylene chopped fiber is the lowest price among all kinds of crack-resistant fibers, and can be used to prevent cracking in the initial stage of cement mortar and concrete hardening To an important role, but the polypropylene chopped fiber will disappear in the later stage. As long as the BFRP cloth is installed on the external wall, the polypropylene chopped fiber can be used to prevent cracking at the initial stage of hardening of the cement mortar. Of course, more advanced and durable ones can be used. Crack resistance fiber, such as cellulose fiber;
b、水泥砂浆或混凝土表面指触干燥后应及时洒水养生,特别是在气温较高时必须经常及时洒水养生,使水泥砂浆抹灰层和现浇混凝土保护层能在潮湿条件下养护,避免养生过程中因缺水使水泥砂浆和现浇混凝土达不到强度要求,发生粉化破坏;同时采用a条和b条为好;因为抹灰的基层是高分子EPS板,EPS板不能如砖墙提前浇水可释放水汽养护水泥砂浆或养护混凝土,洒水养生在绝大多数时候是必要,除非低温雨季;b. After the surface of cement mortar or concrete is dry to the touch, water should be sprayed for curing in time, especially when the temperature is high, it is necessary to spray water for curing in time, so that the cement mortar plaster layer and cast-in-situ concrete protective layer can be cured under humid conditions and avoid curing. In the process, due to lack of water, the cement mortar and cast-in-situ concrete cannot meet the strength requirements, and pulverization damage occurs; it is better to use strip a and strip b at the same time; because the base layer of plastering is a polymer EPS board, the EPS board cannot be like a brick wall Watering in advance can release water vapor to cure cement mortar or curing concrete. Watering is necessary for curing most of the time, except in low temperature and rainy seasons;
⑥还需要执行外墙抹灰施工工法的有关技术规定,如:用经纬仪打出垂直线并挂线作出控制线,在抹灰之前在EPS板上预先贴饼、冲筋(可用水泥聚合物砂浆在EPS板上贴饼、冲筋);在较低温度条件下施工时,还应加入早强剂、防冻剂,保温覆盖等防冻措施避免水泥砂浆或混凝土受到冻害破坏;砂浆或混凝土拌制后要及时用完,避免存放时间过长报废等;⑥ It is also necessary to implement the relevant technical regulations of the external wall plastering construction method, such as: use theodolite to draw a vertical line and hang the line to make a control line. The EPS board is pasted with cakes and reinforced); when constructing at a lower temperature, anti-freezing measures such as early strength agent, antifreeze, and thermal insulation cover should be added to prevent the cement mortar or concrete from being damaged by freezing damage; Use up in time to avoid long storage time and scrap etc.;
以上在EPS板上进行水泥砂浆抹灰的施工工法可以应用于与混凝土墙,砌块墙的抹灰,要求被抹灰的基层墙体干净,在这类墙上进行水泥砂浆抹灰相比在EPS板上抹灰更容易粘接和养生;The above construction method of cement mortar plastering on the EPS board can be applied to the plastering of concrete walls and block walls. The base wall to be plastered is required to be clean. Compared with the cement mortar plastering on this type of wall Plastering on EPS board is easier to bond and maintain health;
上述方法可保证水泥砂浆保护层8-1或屋面现浇混凝土保护层8-2与EPS板可靠粘接,并保证水泥砂浆和混凝土强度符合要求,虽然还可夹入金属网、无机纤维网阻裂,但外墙粘贴安装BFRP布就不需要了;The above method can ensure that the cement mortar protective layer 8-1 or the roof cast-in-place concrete protective layer 8-2 is reliably bonded to the EPS board, and the strength of the cement mortar and concrete meets the requirements, although metal mesh and inorganic fiber mesh can also be inserted. Cracks, but BFRP cloth pasted on the exterior wall is not needed;
6)进一步地,参照实施方式一涂刷胶粘剂,在外墙的水泥砂浆保护层8-1上粘贴安装BFRP布3,并将BFRP布3粘贴到室内窗口侧面,及安装室外预制EPS上人窗台板和门窗口上部保温装饰线条,安装门窗,安装窗口二侧保温装饰线,安装外墙附着物。6) Further, referring to the first embodiment, apply the adhesive, paste and install the

The prefabricated components include prefabricated concrete sandwich panels. , Precast concrete external insulation board and other precast concrete components; the production and processing of prefabricated components is to use low-strength and cheap materials 11 (such as EPS slats) as the edge template strips of the prefabricated edge (including the edge template of the inner edge of the door window Instead of the side template strip of steel or aluminum plate, use adhesive to paste the

本实施方式采用的边模板条是现行建筑预制技术所没有的,现在是焊接或用螺钉将钢板或铝板的边模板条固定在钢平台上,或用价格昂贵的高磁性吸铁石吸住钢模板条固定,因外墙板规格多,门窗口规格多,边模板条周转重复利用率低,边模板条耗量极大,安装边模板条麻烦、用工多,焊接或螺钉固定还破坏钢平台,大大增加预制构件成本;用EPS板边模板条宽约50~100mm,价格低廉,预制的内外叶混凝土可以比中间的保温层缩回一定宽度,如50mm,保温层突出便于接缝连接安装不开裂。可用丙烯酸酯共聚型乳液原浆粘贴EPS板边模板条,粘贴固定简单,拆卸清理边模板条时可用麻丝刀沿着胶粘剂粘接面就可将EPS板条与钢板脱离,不破坏钢平台。EPS板边模板条可作为包装材料与预制构件的混凝土粘贴连接在一起(预制时在EPS板边模板条上涂刷一点胶粘剂,EPS板边模板条就与浇筑的混凝土粘在一起了),预制完成后可用编织包装布把EPS板边模板条与预制构件边缘包裹粘贴保护,直至在施工现场安装预制混凝土夹芯板或预制混凝土外保温板,即边模板条还是预制构件边缘的保护材料,安装边模板条成本仅约5元/m 2,而当前安装金属边模板条需要150~200元/m 2。 The side template strips used in this embodiment are not available in the current building prefabrication technology. Now the side template strips of steel or aluminum plates are fixed on the steel platform by welding or screws, or the steel template strips are absorbed by expensive high-magnetic iron magnets. Fixed, due to the large specifications of external wall panels, door and window specifications, low recycling rate of side template strips, large consumption of side template strips, troublesome installation of side template strips, heavy labor, welding or screw fixing also destroys the steel platform, greatly Increase the cost of prefabricated components; the width of the EPS board side template is about 50-100mm, which is low in price. The prefabricated inner and outer leaf concrete can be retracted to a certain width than the middle insulation layer, such as 50mm. The insulation layer protrudes to facilitate the joint connection and installation without cracking. The EPS board edge template strip can be pasted with acrylic copolymer emulsion puree, which is easy to paste and fix. When removing and cleaning the edge template strip, a hemp knife can be used to detach the EPS board from the steel plate along the adhesive bonding surface without damaging the steel platform. The EPS board edge template strip can be used as a packaging material to glue and connect with the concrete of the prefabricated component (when prefabricating, apply a little adhesive on the EPS board edge template strip, and the EPS board edge template strip will be glued to the poured concrete), prefabricated After completion, you can use woven packaging cloth to wrap the EPS board side template strip and the edge of the prefabricated member for protection, until the prefabricated concrete sandwich panel or prefabricated concrete external insulation board is installed at the construction site, that is, the side template strip is also the protective material for the edge of the prefabricated component. The cost of side formwork strips is only about 5 yuan/m 2 , while the current installation of metal side formwork strips requires 150-200 yuan/m 2 .
非承重混凝土夹芯板既可在平台上预制,也可箱式立模预制,箱式立模预制成本低,但宽度多不满足窗间墙宽度要求,重型混凝土及大跨度预制墙板和预制屋面板不适宜用箱式立模预制。但箱式立模适用于预制室内间隔墙的预制夹芯墙板,预制夹芯墙板宽度600mm~1200mm,立模上下也用EPS做边模板条,同上二侧混凝土比中间保温层2缩回一定宽度,便于窗间墙垂直接缝连接。Non-load-bearing concrete sandwich panels can be prefabricated on the platform or box-type vertical mold prefabrication. The box-type vertical mold prefabrication cost is low, but the width does not meet the width requirements of the window wall. Heavy-duty concrete and large-span prefabricated wall panels and prefabrication The roof panels are not suitable for prefabrication with box-type vertical moulds. However, the box-type vertical form is suitable for prefabricated sandwich wall panels of prefabricated indoor partition walls. The width of the prefabricated sandwich wall panels is 600mm~1200mm. The upper and lower sides of the vertical form also use EPS as side formwork strips, and the two sides of the concrete are more retracted than the
对框架结构安装的预制非承重外墙板(包括预制夹芯外保温墙板或安装预制混凝土外保温板)进行分拆接缝位于窗槛墙上(见图7)或位于门窗口侧边为宜(见图22),比在窗间墙中间分拆安装接缝工作量少得多,预制夹芯屋面板分拆根据预制设备可预制的宽度分拆,各种预制构件规格还受运输条件的限制。Disassemble the prefabricated non-load-bearing external wall panels installed in the frame structure (including prefabricated sandwich external thermal insulation wall panels or install prefabricated concrete external thermal insulation panels). The joints are located on the window sill wall (see Figure 7) or on the side of the door window It should be (see Figure 22), which is much less work than disassembling and installing the joints in the middle of the window wall. The prefabricated sandwich roof panel is disassembled according to the prefabricated width of the prefabricated equipment. The specifications of various prefabricated components are also subject to transportation conditions. limits.
生产加工预制混凝土夹芯板或预制混凝土外保温板的预制加工工法为:The prefabrication method for the production and processing of precast concrete sandwich panels or precast concrete external thermal insulation panels is:
1)应符合建筑行业通用的规定;1) Should comply with the general regulations of the construction industry;
2)应根据设计要求对预制混凝土夹芯板、预制混凝土外保温板进行深化设计,确定预制混凝土夹芯板、预制混凝土外保温板分拆位置,编制构件加工图(含配筋图,若分拆在窗槛墙上在门窗口转角的内外叶混凝土内安装45度斜钢筋为宜),预制混凝土夹芯板或预制混凝土外保温板内的外叶混凝土比保温层2在墙体垂直接缝处及在屋面板相邻接缝处(非支座接缝)缩回一定宽度,如50mm,刚好就是边模板条占据的位置,用于安装时将接缝处保温层2连接;在外墙的预制混凝土夹芯板、预制混凝土外保温板图纸上标明窗口安装不燃保温材料9如竖丝岩棉板,标明安装预埋钢板4和安装预埋吊装件的预埋位置和规格;所述预埋钢板4有窗口室外转角L形预埋钢板4-1和外墙其余位置安装的预埋钢板4-2,建设近零能耗建筑时,L形预埋钢板4-1在窗口侧面的长度不宜伸入窗框内或进入窗框内不大于窗框厚度的50%为宜,预制混凝土夹芯板的L形预埋钢板4-1在窗口侧面长度与外叶混凝土厚度相同为宜,预制混凝土外保温板时L形预埋钢板4-1的规格参照实施方式二;安装窗户时内外交错安装连接为宜,室外将窗户的连接铁件15与L形预埋钢板4-1固定,室内与基层墙体1固定,或室内窗口有预埋钢板4-3(保温层较厚时),安装 窗户的连接铁件15与室内预埋钢板4-3连接,低能耗建筑的室内预埋钢板4-3与室外L形预埋钢板4-1不应连接;L形预埋钢板4-1规格应方便安装窗口周边附着物的施工方便要求;外墙其余位置安装的预埋钢板4-2与外叶混凝土8-3锚固,或预制混凝土外保温板时用胶粘剂将外墙其余位置安装的预埋钢板4-2与EPS板粘贴,也可在预制混凝土外保温板养生完成后用胶粘剂将L形预埋钢板4-1粘贴在窗口不燃保温材料9及外保护层8-1内的EPS板上;预埋钢板4外表面与外叶混凝土8-3平,见图5,或预埋钢板4外表面与预制混凝土外保温板的EPS板平;L形预埋钢板4-1为厚度1.5~2mm的热镀锌钢板为宜,外墙其余位置的预埋钢板4-2为厚度不小于4mm的冷镀锌钢板为宜,对预埋钢板4采取有效防腐蚀措施保证耐久年限不少于50年;2) According to the design requirements, the precast concrete sandwich panel and the precast concrete external thermal insulation board shall be in-depth design, determine the separation position of the precast concrete sandwich panel and the precast concrete external thermal insulation board, and prepare the component processing diagram (including the reinforcement diagram, if divided It is advisable to install 45-degree oblique steel bars in the inner and outer leaves of the corners of the door window on the window sill wall. The outer leaf concrete in the precast concrete sandwich panel or the precast concrete external insulation board is at the vertical joint of the wall than the
3)需对各层材料之间粘接及在EPS板上粘贴安装预埋钢板进行试验,及对框架结构非承重外墙或屋面安装的预制混凝土夹芯板按简支板进行加载试验:3) It is necessary to test the bonding between the materials of each layer and the installation of embedded steel plates on the EPS board, and the loading test of the precast concrete sandwich panels installed on the non-load-bearing external wall or roof of the frame structure according to the simple support board:
①先将浇筑的混凝土(包括轻骨料混凝土)与EPS板与进行粘接试验,破坏应在EPS板上而不是在粘接界面;① Conduct bonding test between the poured concrete (including lightweight aggregate concrete) and the EPS board. The damage should be on the EPS board instead of the bonding interface;
②预先用胶粘剂将预埋钢板粘贴到EPS板上进行粘接试验,及与窗口不燃保温材料如竖丝岩棉板进行粘接试验,以破坏在EPS板上或不燃保温材料上,而不是在粘接界面为合格;②Paste the embedded steel plate on the EPS board with adhesive in advance for bonding test, and conduct bonding test with the window non-combustible thermal insulation material such as vertical silk rock wool board, to damage the EPS board or non-combustible thermal insulation material, but not on the The bonding interface is qualified;
③在试验粘接合格的基础上,需根据设计要求的混凝土强度等级,对不同跨度(如3.3m、3.9m、4.5m、5.1m、6m)、不同断面高度(如断面高度为200mm、250mm、300mm、350mm)的预制混凝土夹芯板进行正截面受弯试验、斜截面抗剪切试验,构件的检测数量应符合规定;这是因为企业从没有预制过各层材料层层粘接的预制混凝土夹芯板的受弯构件,需要进行此项试验;试验时根据不同气候区、不同水平荷载组合值的大小确定EPS板厚度和构件总厚度,例如用于外挂安装的预制混凝土夹芯墙板,层层粘接时内外叶轻骨料混凝土时分别厚60mm、40mm就可满足受弯构件弯曲受压受力层厚度要求和耐火极限要求,可通过变更EPS板厚度变更预制混凝土夹芯板断面高度,变更构件刚度和抗弯有效高度,但基本不增加重量;检测的构件受力性能应符合力学和混凝土结构理论,如若不符应检查分层粘接是否有问题(若分层没有粘接好各层材料之间就不能共同受力,构件刚度大幅度下降导致挠度大);应记录每次施加荷载数据、挠度、裂缝,直至破坏等试验数据,满足裂缝控制等级的规定,并有视频录像等资料为宜,应记录非承重外墙板及预制混凝土夹芯屋面板达到允许挠度限值时的荷载,应做出构件选用表格供设计选用,在预制企业自检的基础上由法定单位检测,此项作为型式检验项目为宜;安装非承重外墙板时若内叶混凝土需要安装网格布阻裂,可将网格布安装在内叶混凝土内接近表面处,网格布的网孔边长10~20mm为宜;超过一定数量的外墙板或屋面板还应按一定比例抽查进行加载试验作为出厂合格的依据;③On the basis of qualified test bonding, it is necessary to test different spans (such as 3.3m, 3.9m, 4.5m, 5.1m, 6m) and different section heights (such as section heights of 200mm, 250mm) according to the concrete strength grade required by the design. , 300mm, 350mm) prefabricated concrete sandwich panels are subjected to normal section bending test and oblique section shear test. The number of components tested should meet the requirements; this is because the company has never prefabricated prefabricated materials that are bonded layer by layer. This test is required for the bending members of concrete sandwich panels; the thickness of the EPS panels and the total thickness of the components are determined according to different climate zones and different horizontal load combinations during the test, such as precast concrete sandwich wall panels for external installation , The thickness of the inner and outer leaves of lightweight aggregate concrete is 60mm and 40mm respectively when bonding layer by layer, which can meet the requirements of the bending pressure bearing layer thickness and the fire resistance limit of the bending member. The section of the precast concrete sandwich panel can be changed by changing the thickness of the EPS board. Height, change the rigidity of the component and the effective height of bending resistance, but basically do not increase the weight; the force performance of the tested component should conform to the mechanics and concrete structure theory. The materials of each layer cannot be stressed together, and the rigidity of the component is greatly reduced, resulting in large deflection); the test data of each load, deflection, crack, and failure should be recorded to meet the requirements of crack control level, and there is video recording It is advisable to record the load when the non-load-bearing external wall panels and precast concrete sandwich roof panels reach the allowable deflection limit, and a component selection form should be made for design selection, and the prefabricated enterprise's self-inspection should be tested by the legal unit This item is appropriate as a type inspection item; if the inner leaf concrete needs to be installed with grid cloth to prevent cracking when installing non-load-bearing external wall panels, the grid cloth can be installed in the inner leaf concrete near the surface, the mesh of the grid cloth The side length should be 10-20mm; the external wall panels or roof panels exceeding a certain number should also be randomly checked according to a certain proportion and carried out a loading test as the basis for leaving the factory;
以上预制混凝土夹芯板或预制混凝土外保温板若不安装BFRP布直接可作为装配式墙板安装,但是不能把窗户离开内叶混凝土安装到靠近窗户外角部位,窗口周边热桥不能消灭,满足建设近零能耗建筑的标准需要安装的EPS板很厚,还不保证框架结构安装的非承重墙体窗间墙抗剪切安全,大风和地震时有可能窗口角部开裂甚至完全破坏,预制构件接缝易开裂,接缝是热桥,接缝密封防水不好;The above precast concrete sandwich panels or precast concrete external insulation panels can be installed directly as fabricated wall panels without installing BFRP cloth, but the windows cannot be installed from the inner leaf concrete to the corners of the windows, and the thermal bridges around the windows cannot be eliminated to meet the construction requirements. The standard for near-zero energy-consumption buildings requires thick EPS panels to be installed, and the non-load-bearing walls of the frame structure are not guaranteed to be shear safe. The corners of the windows may crack or even be completely destroyed during strong winds and earthquakes. Prefabricated components The joints are easy to crack, the joints are thermal bridges, and the joints are not well sealed and waterproof;
4)在用于安装外墙预制混凝土夹芯板的外叶混凝土8-3或在预制混凝土外保温板的外保护层8-1表面粘贴BFRP布3时,需参照实施方式一或二提前将BFRP布与混凝土粘接进行试验、将BFRP布相互粘贴进行试验,将BFRP布与不燃保温材料进行粘接试验;4) When the outer leaf concrete 8-3 used to install the external wall precast concrete sandwich panel or the
5)预制混凝土夹芯板或预制混凝土外保温板时,预制平台上从下至上各层材料的铺装顺序根据预制车间设备条件不同,根据预制方便确定;5) When prefabricated concrete sandwich panels or prefabricated concrete external insulation panels, the paving order of the materials from bottom to top on the prefabricated platform depends on the equipment conditions of the prefabricated workshop and is determined according to the convenience of prefabrication;
6)应提前准备符合设计要求的保温板2和预埋钢板4;6)
①保温板2规格应满足在墙体垂直接缝处或屋面板接缝处阶梯状搭接粘贴或平面对粘要求确定,平整度应符合要求(没有熟化好的大规格EPS板易翘曲,是不可以的),EPS板规格应符合预制混凝土夹芯板要求的规格,EPS板应尽量减少接缝(EPS板最长可达6m、宽度一般是1.22m),EPS板在非承重外墙窗间墙长度方向及屋面板的主要受力方向最好没有接缝,如有接缝采用阶梯型搭接涂刷胶粘剂粘接连接或还有塑料螺栓固定,或为平面时涂刷或刮抹胶粘剂将EPS板接缝对粘连为一体(用加砂的环氧树脂胶粘剂将EPS板对接粘贴很方便,但缝隙较大时应粘贴EPS板填塞缝隙,否则有热桥采暖地区不宜采用),应保证粘接可靠;EPS板边边缘接缝可为阶梯型,在将预制混凝土夹芯板安装到主体结构上时用于搭接粘贴,也可为平面安装时涂刷或刮抹胶粘剂相互挤紧对粘;预制混凝土夹芯屋面板内的EPS板除了接缝侧面应互相粘接外(如有缝隙插入EPS板薄条,EPS板薄条二侧涂刷胶粘剂粘贴),在EPS板接缝上部缝隙还应涂刷防水密封材料2遍进行防水密封,第1遍干燥后涂刷第2遍,确保接缝防水密封可靠;将预制混凝土夹 芯墙板的L形预埋钢板4-1和外墙其余预埋钢板4-2与外叶混凝土8-3锚固,预埋钢板4外表面与外叶混凝土8-3平;预制混凝土外保温板时可先用胶粘剂将L形预埋钢板4-1和外墙其余预埋钢板4-2与EPS板粘接,及与门窗口侧面不燃保温材料9粘接,待粘贴预埋钢板4的胶粘剂固化后再将EPS板放到平台上用于生产加工预制混凝土外保温板,也可以待预制混凝土外保温板养生完成后用胶粘剂将转角L形预埋钢板4-1与窗口不燃保温材料9粘贴及粘贴到外保护层8-1内的EPS板上,及将外墙其余位置安装的预埋钢板4-2与EPS板粘贴,预埋钢板4与EPS板平;①The specifications of
本实施方式屋面的预制混凝土夹芯板内安装的EPS板与实施方式二在屋面板混凝土上安装的EPS板都起保温作用和防水作用,但有不同点:本实施方式的预制混凝土夹芯板在作为屋面板及作为框架结构的预制混凝土夹芯墙板时,EPS板是受弯构件的一部分,EPS板参与受力,所以必须将EPS板相互接缝处的侧面粘接连为一体,否则预制混凝土夹芯板将在EPS板接缝处断裂破坏;若屋面的内叶混凝土能自身满足承载能力就与实施方式二的屋面相同,EPS板相互接缝处的侧面不一定粘贴,但对接缝上部缝隙必须防水密封。装配式安装的预制混凝土夹芯屋面板和预制外保温墙板仅用内叶混凝土自身满足承载力要求是不经济的,因为不能发挥EPS板的受力性能,其抗弯高度仅是内叶混凝土高度,用钢量大,抗弯刚度小,挠度大,而若EPS板与内外叶混凝土粘接为一体,EPS板成为受力构件的一部分参与受力,则抗弯高度是整个预制混凝土夹芯屋面板,抗弯刚度大,变形小,抗剪切承载力大,用钢量小,体现了“团结就是力量”,故将EPS板接缝的侧面粘接连为一体是很重要的;The EPS board installed in the precast concrete sandwich panel of the roof of this embodiment and the EPS board installed on the concrete of the roof slab in the second embodiment have the function of heat preservation and waterproofing, but there are differences: the precast concrete sandwich panel of this embodiment When used as a roof panel and a precast concrete sandwich wall panel as a frame structure, the EPS board is a part of the bending member, and the EPS board participates in the force. Therefore, the sides of the EPS board must be bonded together at the joints of the EPS boards. Otherwise, The precast concrete sandwich panels will break and fail at the joints of the EPS panels; if the inner leaf concrete of the roof can meet the load-bearing capacity of the roof, it will be the same as the roof of the second embodiment. The upper gap of the seam must be waterproof and sealed. It is not economical for prefabricated concrete sandwich roof panels and prefabricated external thermal insulation wall panels to use only the inner leaf concrete to meet the bearing capacity requirements, because the force performance of the EPS board cannot be used, and its bending height is only the inner leaf concrete High steel consumption, small bending stiffness, large deflection, and if the EPS board is bonded with the inner and outer leaf concrete, the EPS board becomes a part of the force-bearing member to participate in the force, then the bending height is the entire precast concrete sandwich The roof panel has high flexural rigidity, small deformation, high shear resistance, and small amount of steel, which embodies "unity is strength". Therefore, it is very important to bond the sides of the EPS board as a whole;

实施方式八:本实施方式的一种高科技时代低碳社会的建筑技术,见图13,是一种将消震减震材料用于建筑物基础消能减震构造,它是由建筑主体结构的基础20、地基30、消震减震材料40组成;所述基础20是各种基础,如箱基础、整板基础、条板基础、柱下独立基础、基础地梁、箱形基础或整板加桩的基础、桩基础承台板、桩基础承台梁、砌筑砖基础、石基础等;所述消震减震材料40是具有弹性的材料,消震减震材料40的弹性恢复率、压缩强度和耐久性应满足使用要求,如消震减震材料40是天然橡胶、合成橡胶、弹性体材料,还如闭孔聚乙烯一次发泡塑料PE板等;在基础20与地基30之间安装消震减震材料40,建筑的基础施工时,将消震减震材料40铺放安装在地基30上,然后在消震减震材料40上浇筑基础20混凝土或其它基础,即基础20与地基30之间安装有消震减震材料40。从当前看,具有施工方便性的消震减震材料是聚氨酯弹性体,聚氨酯弹性体具有吸震性能,其硬度、强度等性能可调范围大,有多种成形方式,施工安装方便。将预制的聚氨酯弹性体TPU(微孔为宜)铺设在地基上,在施工现场可用浇筑的聚氨酯弹性体CPU(微孔为宜)将预制的聚氨酯弹性体之间缝隙粘接连接,安装在建筑基础下的聚氨酯弹性体不仅是消震减震材料的阻尼,还成为基础底部的防水层。有桩基础时,可在桩基础钻孔内安装消震减震材料的圆筒,消震减震材料40的圆筒可以是闭孔聚乙烯一次发泡塑料PE板,价格低,将消震减震材料板材弯成圆筒状,接缝可热熔粘接或用聚硫胶粘接,将每段圆筒之间连接防水,再在消震减震材料40圆筒内浇筑桩基础混凝土。Embodiment 8: The construction technology of a low-carbon society in the high-tech era of this embodiment, as shown in Fig. 13, is a kind of shock-absorbing and shock-absorbing material used in the building foundation energy-dissipating and shock-absorbing structure. The
进一步地,它还增加颗粒材料,在消震减震材料40内添加颗粒材料,颗粒也是阻尼。如颗粒是陶粒颗粒,陶粒价格低,若用铝球、塑料球做为颗粒价格高;陶粒颗粒密度约400~900kg/m3,筒压强度不小于1.5MPa;在将聚氨酯弹性体注入模具内时,可分层添加适当粒径、适当密度、适当筒压强度,满足耐久性要求的的颗粒材料,注入的聚氨酯弹性体将颗粒材料包裹,既降低成本又增加消震减震材料40的阻尼和压缩强度。Furthermore, it also adds granular materials, and granular materials are added to the shock-absorbing and shock-absorbing
经济分析:假定基础是整板基础,建筑层数为20~30层,基础地面面积比每层的建筑面积稍大一点,在基础下安装50~100mm厚聚氨酯弹性体板TPU,材料价格+人工费约1250~2500元/m 2,安装聚氨酯弹性体增加的造价分摊到每层面积上约(60~90)元/m 2,但因可减少建筑主体结构以刚克刚的钢材和混凝土用量,从而降低建筑主体结构造价可超过(60~90)元/m 2,特别是在罕遇地震发生时建筑物不会破坏,既大幅度降低建筑造价又避免地震时破坏,具有重要意义。 Economic analysis: Assuming that the foundation is a whole slab foundation, the number of building floors is 20-30, and the ground area of the foundation is slightly larger than the building area of each floor. 50-100mm thick polyurethane elastomer board TPU is installed under the foundation, material price + labor The cost is about 1250~2500 yuan/m 2 , and the increased cost of installing polyurethane elastomer is allocated to about (60~90) yuan/m 2 on each floor area, but it can reduce the amount of steel and concrete used for the main structure of the building. , So as to reduce the cost of the main structure of the building by more than (60-90) yuan/m 2 , especially when the building will not be damaged in the rare earthquake, it is of great significance to greatly reduce the building cost and avoid damage during the earthquake.
或/和在地下外墙的墙体侧面粘贴安装保温材料,如安装发泡塑料如XPS板,或在地下墙体侧面粘贴安装除当前墙体保温材料以外的其它具有较大弹性的发泡材料作为保温材料,如闭孔聚乙烯一次发泡塑料PE板,将其它发泡材料安装在地下墙体侧面的作用是:不仅具有保温作用,且地震发生时,地下墙体上粘贴的其它发泡材料可缓冲地震时土的推力对地下墙体的作用。但PE类发泡材料是难以粘接的材料,用聚硫胶可将闭孔聚乙烯一次发泡塑料PE板与墙体粘贴。Or/and paste and install thermal insulation materials on the side of the underground exterior wall, such as installing foamed plastic such as XPS board, or paste and install other foam materials with greater elasticity besides the current wall thermal insulation materials on the side of the underground wall As a thermal insulation material, such as closed-cell polyethylene primary foamed plastic PE board, the function of installing other foaming materials on the side of the underground wall is: not only has a thermal insulation effect, but also other foams pasted on the underground wall when an earthquake occurs The material can buffer the effect of the thrust of the soil on the underground wall during an earthquake. However, PE foaming materials are difficult to bond. Polysulfide glue can be used to glue the closed-cell polyethylene foamed plastic PE board to the wall.
或进一步地,增加塑料膜50,将塑料膜50如LDPE膜安装在弹性体材料40的下面或还粘贴在侧面,以及粘贴到地下外墙侧面,或还在建筑地基之间的室内基础之间的地基上铺设塑料膜50。聚氨酯弹性体可能滋生霉菌,在聚氨酯弹性体下面和侧面安装LDPE膜可保护聚氨酯弹性体,LDPE膜接缝可热熔焊接或用聚硫胶粘接,价格低。LDPE膜柔韧性高,抗拉伸长率大,耐环境性强,虽可用某些防水卷材替代塑料膜50,但防水卷材价格高、接缝麻烦易漏水。地下工程防水历来是建筑的难题,本实施方式在弹性体材料下面安装塑料膜,及安装LDPE膜作为地下工程防水层(接缝焊接),可彻底解决地下工程防水难题,造价低,耐久性好,降低地下防水工程造价,因此虽然安装消震减震材料40但可能降低造价。Or further, add a
实施方式九:本实施方式的一种高科技时代低碳社会的建筑技术,见图14、图15,是一种将框架结构的室内间隔墙安装为阻尼墙的建筑技术:它是由建筑主体结构10、墙体25和弹性体材料40组成;在墙 体25与建筑主体结构10的梁10-1、柱间预留一定宽度的缝隙,缝隙内安装弹性体材料40,如弹性体材料是注入的聚氨酯弹性体CPU(微孔为宜),弹性体材料40将室内间隔墙的墙体25与建筑主体结构10粘接连接,弹性体材料40是室内间隔墙的阻尼,需在聚氨酯弹性体外侧采取涂刷防火涂料等措施,框架结构的室内间隔墙成为阻尼墙体,可在墙体25与建筑主体结构10之间安装压缩弹簧,以避免一旦失火间隔墙倒塌;所述室内间隔墙为非保温墙体或为夹芯保温墙体,夹芯保温墙体中间有EPS板保温层,或保温层为其它适应变形且可传递应力的保温材料,将EPS板保温层之间接缝相互粘接,EPS板与二侧墙体25互相粘接,EPS板四边与建筑主体结构10的梁10-1、柱10-2之间粘接;所述二侧墙体25是装配式安装的预制板材,如蒸压加气混凝土板或石膏混凝土板,或二侧墙体25是砌体墙。Embodiment 9: This embodiment is a low-carbon society construction technology in the high-tech era, as shown in Figures 14 and 15. It is a construction technology that installs a frame structure indoor partition wall as a damping wall: it is composed of the main body of the building. The
EPS板是软泡材料,在变形不大于5%时位于弹性范围内,将EPS板与建筑主体结构的梁柱粘贴,上下层之间发生角位移时,EPS板就成为室内间隔墙的阻尼,增加了室内间隔墙的阻尼效果。本实施方式将节能保温墙体技术与消震减震技术相统一。现在有的提出阻尼墙是二侧钢板中间夹专用沥青,既不隔音又不保温,重量重,防火不好,造价高。本实施方式安装简单、方便。The EPS board is a soft foam material. When the deformation is not more than 5%, it is within the elastic range. The EPS board is pasted with the beams and columns of the main structure of the building. When the angular displacement occurs between the upper and lower layers, the EPS board becomes the damping of the indoor partition wall. Increase the damping effect of the indoor partition wall. In this embodiment, the energy-saving and thermal insulation wall technology is unified with the shock-absorbing and shock-absorbing technology. It is now proposed that the damping wall is made of special asphalt sandwiched between two steel plates, which is neither sound insulation nor heat preservation, heavy in weight, poor in fire resistance, and high in cost.

关于胶粘剂使用说明:Instructions on the use of adhesives:
以下各条是本发明可采用的胶粘剂,仅供参考。因胶粘剂是化工领域的一个庞大的体系,品种多,各个生产厂家生产相同品种的胶粘剂都有差异,下面配合比仅供参考,希望达到以下效果:The following items are the adhesives that can be used in the present invention, for reference only. Because adhesives are a huge system in the chemical industry with many varieties, different manufacturers produce the same types of adhesives. The following mixing ratios are for reference only. Hope to achieve the following effects:
1)希望工程在使用胶粘剂过程中进行完善,一切以粘接试验是否合格为准。可能还有其它可满足本发明使用要求的胶粘剂,且新品种胶粘剂不断出现,只要无毒无害,满足粘接强度和耐久性要求都可以使用,可替代本发明提供参考使用的胶粘剂,有的粘接界面可选用不止一种胶粘剂,根据施工方便选用。1) It is hoped that the project will be perfected in the process of using the adhesive, and everything depends on whether the bonding test is qualified. There may be other adhesives that can meet the requirements of the present invention, and new types of adhesives continue to appear. As long as they are non-toxic and harmless, they can be used to meet the requirements of bonding strength and durability. They can replace the adhesives used by the present invention as a reference. Some More than one type of adhesive can be used for the bonding interface, which can be selected according to the convenience of construction.
2)节能保温工程离不开胶粘剂,工程管理者熟悉胶粘剂,对保证节能保温工程质量至关重要,希望工程管理者在使用胶粘剂中熟悉胶粘剂,可灵活掌握配合比,在配制聚合物胶粘剂时通过调整水泥基丙烯酸酯乳液或调整水泥基丙烯酸酯共聚型乳液的含量,以及调整其它外加材料的含量,满足不同粘接要求。2) Adhesives are indispensable for energy-saving and thermal insulation projects. Project managers are familiar with adhesives, which is very important to ensure the quality of energy-saving thermal insulation projects. It is hoped that project managers can be familiar with adhesives in the use of adhesives, and be able to flexibly control the mixing ratio, and pass when preparing polymer adhesives. Adjust the cement-based acrylate emulsion or the content of the cement-based acrylate copolymer emulsion, and adjust the content of other additional materials to meet different bonding requirements.
第1条 将预埋钢板或抗侧移斜撑粘贴到EPS板或粘贴到其它保温层上,选用环氧树脂胶粘剂粘贴(可加砂),或选用除水溶性胶粘剂以外的其它胶粘剂粘贴,胶粘剂应满足粘接强度、耐久性要求。钢件与保温层之间的粘接试验,以及保温层与基层之间的粘接试验,破坏均应发生在保温层上,而不是破坏在粘接界面上为合格,现在有可在潮湿基层上粘贴的环氧树脂胶粘剂。虽然用浓度较高的水溶性胶粘剂如水泥基丙烯酸酯共聚型乳液配制的胶粘剂也可以将预埋钢板与EPS板粘贴,但增加对每个预埋钢板检测工作量,影响施工进度,麻烦,不可行。也可用环氧树脂胶粘剂(可加砂)将EPS板或其它保温板与基层粘贴。
各地自然环境不同,空气中酸雨等腐蚀物质含量不同。为提高预埋钢板耐久年限,对预埋钢板除采用通长的防腐蚀措施,如用热镀锌钢板或冷镀锌钢板外,还需在环氧树脂胶粘剂内加入其它材料改性,增加其防腐蚀性能,如加入一定数量高径厚比(径厚比不低于180倍为宜,甚至可达200倍)、高纯度(约99%),满足一定细度要求的的层状粉体如云母粉和辅料(少量膨润土等)或加入高径厚比玻璃鳞片搅拌均匀,数量应试验确定。环氧树脂本身就是防腐材料,添加层状粉体后又大大增加防腐效果,云母粉的高径厚比使其具有“屏蔽效应”、“迷宫效应”,使水分和其它各种腐蚀性物质穿过环氧树脂的时间大幅度延长,因而具有优良的耐酸碱性能,使环氧树脂胶粘剂成为防腐环氧树脂胶粘剂。用防腐环氧树脂胶粘剂粘贴各种钢件,在预埋钢板或抗侧移斜撑等钢件内外表面涂敷的环氧树脂胶粘剂满足一定厚度,提高预埋钢板或抗侧移斜撑等钢件防腐耐久年限。The natural environment varies from place to place, and the content of corrosive substances such as acid rain in the air is different. In order to improve the durability of the embedded steel plate, in addition to adopting long-term anti-corrosion measures for the embedded steel plate, such as hot-dip galvanized steel or cold-galvanized steel, it is also necessary to add other materials to modify the epoxy resin adhesive to increase its Anti-corrosion performance, such as adding a certain amount of layered powder with high-diameter ratio (diameter-thickness ratio is not less than 180 times, even up to 200 times), high purity (about 99%), and meeting certain fineness requirements Such as mica powder and auxiliary materials (a small amount of bentonite, etc.) or add high-diameter-thickness ratio glass flakes and stir evenly, the quantity should be determined by experiment. Epoxy resin itself is an anti-corrosion material. The addition of layered powder greatly increases the anti-corrosion effect. The high-diameter-thickness ratio of mica powder makes it have "shielding effect" and "labyrinth effect", allowing moisture and other corrosive substances to penetrate The time to pass the epoxy resin is greatly extended, so it has excellent acid and alkali resistance, making the epoxy resin adhesive become an anticorrosive epoxy resin adhesive. Paste various steel parts with anti-corrosion epoxy resin adhesive. The epoxy resin adhesive coated on the inner and outer surfaces of steel parts such as embedded steel plates or anti-side shifting braces meets a certain thickness to improve the embedded steel plates or anti-side shifting braces and other steels. Pieces of anti-corrosion and durability.
第2条 水泥聚合物砂浆:将保温板粘贴到基层上(墙体或屋面),或将蒸压加气混凝土板与保温层如EPS板粘接时,及实施方式五将加气混凝土半成品外保温板用作施工现场作为现浇内叶混凝土的外模板,及实施方式六将半成品预制保温板用作施工现场作为现浇内叶混凝土的外模板,在保温板内侧涂刷或刮抹的胶粘剂用水泥聚合物砂浆。可以用本条水泥聚合物砂浆粘贴,也可用第1条的胶粘剂粘接,只要粘接破坏位于保温板而不是位于粘接界面上或满足抗拉强度要求,并满足无污染和耐久性要求即可;或大部分面积用水泥聚合物砂浆粘贴,局部面积面积用不怕潮湿的环氧树脂胶粘剂粘贴。
配制液料——选用具有强附着力、耐水性、耐久性优良的水泥基丙烯酸酯共聚型乳液配制,在乳液原浆内加入一定数量的水稀释,乳液与水的比例是,乳液∶水=1∶(1.5~2.0)为宜,还可加入酸碱度调节剂如(AMP-95),测试稀释的乳液PH值达到8或比8稍高一点为宜,不宜用火碱或食用碱作为酸碱度调节剂;然后在中性稀释的乳液中加入纤维素醚MC约(1~2)%,呈粘稠状搅拌均匀,随配制随使用时不需要加入防腐剂。Preparation of liquid material——Cement-based acrylate copolymer emulsion with strong adhesion, water resistance and excellent durability is selected. A certain amount of water is added to the original emulsion for dilution. The ratio of emulsion to water is emulsion: water = 1: (1.5~2.0) is appropriate, and pH regulator such as (AMP-95) can also be added. It is advisable to test the diluted emulsion with a pH value of 8 or a little higher than 8. It is not suitable to use caustic soda or edible alkali as pH adjustment Agent; then add about (1~2)% of cellulose ether MC to the neutrally diluted emulsion, and mix it evenly in a viscous state. There is no need to add preservatives with the preparation and use.
配制粉体——将水泥(含3%~5%硅灰为宜,硅灰即微硅粉,硅灰的小尺寸作用又增加粘接效果和抗拉强度),或在水泥中加入占水泥重量2%~3%的纤维素醚MC,则在乳液中不必加入纤维素醚MC,将水泥、硅灰、纤维素醚MC搅拌均匀。水泥与砂的比例是:水泥(含硅灰、纤维素醚MC)∶净砂(含泥量≤3%)=1∶(0.8~1.5),混合搅拌均匀(若砂潮湿应随用随加砂搅拌);与加气混凝土板粘贴时,若加气混凝土板表面较光滑时用40~100目石英砂或还加凿毛为宜,视粗糙度不同调整。Powder preparation-cement (containing 3% to 5% silica fume is appropriate, silica fume is micro silica fume, and the small size of silica fume increases the bonding effect and tensile strength), or add the cement to the cement If the cellulose ether MC is 2% to 3% by weight, the cellulose ether MC does not need to be added to the emulsion, and the cement, silica fume, and cellulose ether MC are mixed uniformly. The ratio of cement to sand is: cement (containing silica fume, cellulose ether MC): clean sand (mud content ≤ 3%) = 1: (0.8 ~ 1.5), mix and stir evenly (if the sand is wet, add it as needed Sand mixing); when pasting with aerated concrete slab, if the surface of the aerated concrete slab is smooth, 40-100 mesh quartz sand or chiseling is appropriate, depending on the roughness.
加入纤维素醚MC的数量以配制的水泥聚合物砂浆粘稠度适当为适宜,通过试验调整。The amount of cellulose ether MC added is appropriate for the viscosity of the prepared cement polymer mortar, and it is adjusted through experiments.
再将配制好的粉体加入到已经配制好搅拌均匀的液料中,还加入消泡剂、分散剂,加入的数量以粉体分散好、不起泡为准,将粉体和液料搅拌均匀呈粘稠状方便刮抹的水泥聚合物砂浆。Then add the prepared powder to the well-mixed liquid material, and add the defoamer and dispersant. The amount added is subject to the powder dispersion and no foaming. Stir the powder and liquid Cement polymer mortar that is evenly viscous and easy to wipe off.
纤维素醚MC保水性好,纤维素醚MC应采用分散性好、保水性好的甲基纤维素醚,纤维素醚MC的添加量和MC的保水性直接影响水泥聚合物砂浆是否粘稠、保水效果是否好,是关系到水泥是否能充分水化的重要问题。不同纤维素醚MC在不同温度下的保水性不同,不同厂家的纤维素醚MC保水性不同,添加纤维素醚MC的数量可参照厂家说明书添加,试验配制。室外最高温度不高于35℃时,可用羟丙基甲基纤维素醚,室外最高温度高于35℃时应采用改性的羟乙基甲基纤维素醚,保证高温时的保水性能。Cellulose ether MC has good water retention. Cellulose ether MC should use methyl cellulose ether with good dispersibility and good water retention. The addition amount of cellulose ether MC and the water retention of MC directly affect whether the cement polymer mortar is viscous, Whether the water retention effect is good is an important issue related to whether the cement can be fully hydrated. Different cellulose ether MC has different water retention properties at different temperatures. The water retention capacity of cellulose ether MC from different manufacturers is different. The amount of cellulose ether MC added can be added according to the manufacturer's instructions for test preparation. When the maximum outdoor temperature is not higher than 35°C, hydroxypropyl methyl cellulose ether can be used, and when the maximum outdoor temperature is higher than 35°C, modified hydroxyethyl methyl cellulose ether should be used to ensure water retention performance at high temperatures.
第3条 界面剂:将水泥砂浆抹灰或现浇混凝土与EPS板粘接用胶粘剂,或EPS板接缝处侧面相互之间粘接用胶粘剂(不包括屋面EPS板缝隙上端密封防水),俗称为界面剂,选用具有强附着力、耐水性、耐久性优良的水泥基丙烯酸酯共聚型乳液加水稀释又加入其它材料配制的胶粘剂。
与第2条相同将乳液加水稀释,及加入酸碱度调节剂如(AMP-95),测试稀释的乳液PH值达到8或比8稍高一点为宜,在中性稀释的乳液中加入纤维素醚MC(1~2)%,呈粘稠状搅拌均匀,随着配制随着使用时不需要加入防腐剂。Dilute the emulsion with water and add a pH regulator such as (AMP-95) as in the second item. Test the pH of the diluted emulsion to reach 8 or a little higher than 8, and add cellulose ether to the neutrally diluted emulsion. MC(1~2)%, it is viscous and stirred evenly. There is no need to add preservatives as it is prepared and used.
粉体为水泥,将水泥(含3%~5%硅灰为宜,搅拌均匀),将水泥加入配制好的液料中,还加入消泡剂、分散剂,将粉体和液料搅拌均匀呈稀浆糊状,即为界面剂。将界面剂涂在EPS板上应呈湿润饱满状, 不易很快干燥,不宜流淌。界面剂不需要加砂,当然加砂成为水泥聚合物砂浆也可以粘接,但增加劳动量。The powder is cement. Mix the cement (with 3% to 5% silica fume is suitable and mix well), add the cement to the prepared liquid material, add defoamer and dispersant, and mix the powder and liquid material evenly In the form of a thin paste, it is an interface agent. The interface agent applied to the EPS board should be moist and full, not easy to dry quickly, and not suitable for flow. The interface agent does not need to add sand, of course, adding sand to become cement polymer mortar can also be bonded, but it increases labor.
加入的水泥量少可方便涂刷,因此需要将纤维素醚MC加入到配制的液料中,以保证胶粘剂的保水性,而将纤维素醚MC加入到水泥中可能纤维素醚MC添加量不足,不能起到需要的保水作用。The added amount of cement is small to facilitate painting, so it is necessary to add cellulose ether MC to the prepared liquid material to ensure the water retention of the adhesive, and adding cellulose ether MC to cement may not add enough cellulose ether MC , Can not play the role of water retention required.
需经试验证明,在EPS板上涂刷界面剂后抹水泥砂浆或浇筑混凝土,养生后敲断断面可见胶粘剂渗入EPS板内3~5mm为宜,拉拔或掰开EPS板与混凝土的粘接面,破坏应在EPS板上,即为粘接合格。应提前进行粘接试验,确定的配合比应偏于安全。或可将本条的界面剂与第2条的水泥聚合物砂浆配合使用,在EPS板上涂刷本条的界面剂再抹第2条的水泥聚合物砂浆粘接。Tests are needed to prove that after applying the interface agent on the EPS board, apply cement mortar or pour concrete. After curing, the adhesive can penetrate into the EPS board by 3~5mm after curing. Surface, the damage should be on the EPS board, that is, the bonding is qualified. The bonding test should be carried out in advance, and the determined mix ratio should be safe. Or the interface agent of this article can be used in conjunction with the cement polymer mortar of
丙烯酸酯共聚型乳液可加工为可再分散性干胶粉,但可再分散性干胶粉生产时为提高现场速溶性,需添加聚乙烯醇,聚乙烯醇是非常容易生物降解的,所以直接使用乳液型胶粘剂好。但并不排除使用丙烯酸酯共聚型乳液加工的可再分散性干胶粉,试验证明用可再分散性干胶粉粘接可靠也是可以的,但是否能确认选用的可再分散性干胶粉内聚乙烯醇的含量不超过允许值是很难的。直接购买化工企业生产的具有强附着力、耐水性、耐久性优良的丙烯酸酯共聚型乳液,用其配制聚合物胶粘剂成本低,乳液的用量具有透明度,可保证粘接质量,工程管理人员对控制质量心中有数。各种水溶性胶粘剂的固话物含量都约为50%,虽然也可选用醋酸乙烯-乙烯乳液等粘接,但是其附着力、耐久性、防水性都不如丙烯酸酯共聚型乳液;丙烯酸酯乳液的防水性、耐久性较好,但与EPS板粘接的亲和性不好,丙烯酸酯乳液及其配制的聚合物可用于将BFRP布与混凝土或水泥砂浆粘贴,以及配制水泥聚合物防水涂料涂刷到混凝土上。Acrylate copolymer emulsion can be processed into redispersible dry rubber powder, but in order to improve on-site instant dissolution during the production of redispersible dry rubber powder, polyvinyl alcohol needs to be added. Polyvinyl alcohol is very easy to biodegrade, so it is directly It is good to use emulsion adhesive. However, it does not rule out the use of redispersible dry rubber powder processed by acrylate copolymer emulsion. Tests have proved that it is possible to use redispersible dry rubber powder to bond reliably, but can it be confirmed whether the selected redispersible dry rubber powder can be confirmed It is difficult for the content of internal polyvinyl alcohol not to exceed the allowable value. Directly purchase acrylate copolymer emulsions with strong adhesion, water resistance and excellent durability produced by chemical companies. The cost of preparing polymer adhesives with them is low, and the amount of emulsion is transparent, which can ensure the bonding quality. Engineering management personnel can control Quality knows it well. The solid content of various water-soluble adhesives is about 50%, although vinyl acetate-ethylene emulsion can also be used for bonding, but its adhesion, durability, and water resistance are not as good as acrylate copolymer emulsions; acrylate emulsions The water resistance and durability are good, but the affinity with EPS board is not good. Acrylic emulsion and its formulated polymer can be used to paste BFRP cloth with concrete or cement mortar, and to prepare cement polymer waterproof coating Paint onto the concrete.
第4条 将不燃保温材料与有机保温层粘接,随着不燃保温材料种类不同选用的胶粘剂有所区别。
例如,不燃保温材料是竖丝岩棉板或是发泡水泥板,可用环氧树脂胶粘剂(可加细砂)粘接,或参照第2条用水泥聚合物砂浆粘贴(粘贴面较平整时砂为细砂)。For example, the non-combustible thermal insulation material is vertical silk rock wool board or foamed cement board, which can be bonded with epoxy resin adhesive (fine sand can be added), or glued with cement polymer mortar according to Article 2 (sand when the sticking surface is flat For fine sand).
第5条 将BFRP布粘贴到不燃保温材料及粘贴到预埋钢板上,及粘贴到水泥砂浆或混凝土上(包括与加气混凝土板粘接),推荐选用耐水性、耐久性优良的水泥基丙烯酸酯共聚型乳液或水泥基丙烯酸酯乳液,乳液的玻璃化温度不应高于使用环境最低气温。
配制液料——乳液与水的比例是,乳液∶水=1∶(0.5~1.5)为宜,乳液比例多一些粘接效果好,增加防水效果。同上加入纤维素醚MC(占乳液的1~2)%,还可加入酸碱度调节剂如(AMP-95),测试稀释的乳液PH值达到8或比8稍高一点为宜,然后在中性稀释的乳液中加入纤维素醚MC约(1~2)%,呈粘稠状搅拌均匀,随配制随使用时不需要加入防腐剂。The ratio of liquid material-emulsion to water is: emulsion:water=1:(0.5~1.5). The more the ratio of emulsion is better for bonding effect and increasing waterproof effect. Same as above, add cellulose ether MC (accounting for 1 to 2)% of the emulsion, and also add a pH regulator such as (AMP-95). It is advisable to test the diluted emulsion with a pH value of 8 or a little higher than 8, and then in neutral About (1-2)% of cellulose ether MC is added to the diluted emulsion, and it is viscous and stirred evenly. There is no need to add preservatives during preparation and use.
或在乳液胶粘剂原浆内还添加1.5%的偶联剂如KH550、KH560、KH570,试验选用,搅拌均匀后用乳液直接粘贴。若不添加偶联剂能达到好的粘接效果则可不添加偶联剂。Or add 1.5% coupling agent such as KH550, KH560, KH570 to the original slurry of the emulsion adhesive. The test is selected, and the emulsion is directly pasted after stirring. If no coupling agent can be added to achieve a good bonding effect, no coupling agent can be added.
配制粉体——水泥(若乳液中没有加入纤维素醚MC,水泥中应加入纤维素醚MC)∶净砂(含泥量≤3%)=1∶(0.5~0.8),视被粘面粗糙度不同而调整砂的目数和数量,若与竖丝岩棉板粘贴可不加砂。砂潮湿时应随用随加砂与水泥混合搅拌,BFRP布外为涂料装饰时将净砂换做径厚比不小于50的绢云母粉为宜,水泥(含硅灰、纤维素醚MC)∶绢云母粉=1∶(0.1~0.4),可增加防水效果。Preparation of powder-cement (if cellulose ether MC is not added to the emulsion, cellulose ether MC should be added to the cement): clean sand (mud content ≤ 3%) = 1: (0.5 ~ 0.8), depending on the surface to be adhered Adjust the mesh number and quantity of sand for different roughness. If it is pasted with vertical silk rock wool board, no sand can be added. When the sand is wet, it should be mixed and stirred with the sand and cement. When the BFRP cloth is decorated with paint, it is advisable to replace the clean sand with sericite powder with a diameter-to-thickness ratio of not less than 50. Cement (containing silica fume, cellulose ether MC) :Sericite powder=1:(0.1~0.4), can increase the waterproof effect.
将液料与水泥粉料用电钻搅拌均匀呈浆糊状,粉料掺量不宜多否则影响粘接效果,以方便涂刷不流挂粘稠度为适宜,即可用于粘贴BFRP布,应避免漏涂漏粘。Stir the liquid material and cement powder material evenly with an electric drill to form a paste. Do not mix too much powder material, otherwise it will affect the bonding effect, so as to facilitate the painting and not sag. The viscosity is suitable, and it can be used to paste BFRP cloth. Missing coating and sticking.
在BFRP布粘贴到室内窗口侧面内叶混凝土上,若内叶混凝土较薄如仅60mm时,用水溶性乳液胶粘剂粘接因粘贴面积窄不满足抗剪切承载力要求时,可用纤维浸滞结构胶粘贴BFRP布,需经过试验证明用纤维浸滞结构胶粘贴BFRP布粘贴满足结构设计要求的抗剪切承载力要求,或将BFRP布转而粘贴到室内侧墙面上。因所有乳液都容易与混凝土粘接,故本条不需要强调乳液具有强附着力。When the BFRP cloth is pasted on the inner leaf concrete on the side of the indoor window, if the inner leaf concrete is thinner, such as only 60mm, use a water-soluble emulsion adhesive to bond it. If the adhesive area is narrow and does not meet the shear resistance requirements, fiber impregnated structural adhesive can be used To paste BFRP cloth, it is necessary to verify that the BFRP cloth pasted with fiber impregnated structural glue meets the shear resistance requirements of the structural design requirements, or the BFRP cloth is pasted on the indoor side wall instead. Since all emulsions are easy to bond with concrete, this article does not need to emphasize that emulsions have strong adhesion.
第6条 将BFRP布互相搭接粘贴用胶粘剂,将EPS板作为预制构件的边模板条粘贴在钢平台或预制的箱式模具内时,可用第5条胶粘剂或用乳液胶粘剂原浆粘贴。Article 6 Adhesives for overlapping and pasting BFRP cloths and EPS boards as prefabricated side template strips in a steel platform or a prefabricated box mold can be pasted with the fifth adhesive or emulsion adhesive paste.
第7条 用于屋面EPS板缝隙上端涂刷或刮抹的防水密封材料,所述防水密封材料分为第1遍防水密封材料和第2遍防水密封材料。
液料:第1遍防水密封材料选用具有强附着力、耐水性、耐久性优良的水泥基丙烯酸酯共聚型乳液原浆,配制第2遍防水密封材料所用乳液为水泥基丙烯酸酯共聚型乳液或水泥基丙烯酸酯乳液原浆,配制第2遍防水密封材料乳液的玻璃化温度应不高于当地最低气温。乳液原浆内禁加水,因加水必然增加粉体,影响防水密封材料弹性。Liquid material: the first pass waterproof sealing material is made of cement-based acrylate copolymer emulsion protoplasm with strong adhesion, water resistance and excellent durability, and the emulsion used in the second pass waterproof sealing material is cement-based acrylate copolymer emulsion or The glass transition temperature of the cement-based acrylic emulsion protoplasm and the second water-proof sealing material emulsion should not be higher than the local minimum temperature. It is forbidden to add water in the emulsion puree, because adding water will inevitably increase the powder and affect the elasticity of the waterproof sealing material.
配制粉体——水泥(可含3%~5%硅灰)∶绢云母径厚比不小于50=1∶(10%~20%),搅拌混合均匀。Prepare powder-cement (may contain 3% to 5% silica fume): sericite diameter to thickness ratio not less than 50=1: (10% to 20%), stir and mix evenly.
在乳液原浆内加入配制的粉体,及加入分散剂、消泡剂适量,搅拌均匀后呈便于涂刷或刮抹的浆糊状 聚合物。在屋面EPS板缝隙上端涂刷第1遍防水密封材料,干燥后涂刷第2遍防水密封材料,应先试验可与EPS板粘接再应用于工程中。此防水密封材料实质就是水泥聚合物防水涂料,也可购买建材市场上的水泥聚合物防水涂料,但购进的防水涂料应满足本条要求。乳液原浆干燥后形成的胶膜就是防水胶层,耐紫外线性能好,乳液中水分蒸发后变薄,加入粉体可增厚,但加入粉体多弹性差还影响与EPS板粘接且不方便涂刷,在缝隙处二次涂刷防水密封材料再加上安装屋面EPS板时侧面涂刷第3条的界面剂粘接连为一体,可保证防水可靠。聚丙烯酸酯乳液或丙烯酸酯共聚型乳液是现在配制JS防水涂料的乳液原料,加入粉体就相似于配制水泥聚合物防水涂料,但本发明防水密封材料加入的粉体数量少,满足玻璃化温度乳液的防水胶层柔软对防水更有利,在EPS板上面再浇筑的屋面混凝土保护EPS板和防水密封材料。Add the prepared powder into the original emulsion, and add appropriate amount of dispersant and defoamer. After stirring, it will become a paste-like polymer that is convenient for brushing or scraping. Apply the waterproof sealing material for the first pass on the upper end of the roof EPS board gap, and apply the waterproof sealing material for the second pass after drying. It should be tested to be able to bond with the EPS board before being used in the project. This waterproof sealing material is essentially a cement polymer waterproof coating. Cement polymer waterproof coatings in the building materials market can also be purchased, but the purchased waterproof coatings should meet the requirements of this article. The adhesive film formed after the emulsion syrup is dried is the waterproof adhesive layer, which has good UV resistance. The water in the emulsion becomes thin after evaporation. Adding powder can increase the thickness, but the poor elasticity of the powder will also affect the adhesion to the EPS board. It is convenient to paint. The waterproof sealing material is applied twice at the gap and the interface agent of
目前所知具有强附着力、耐水性、耐久性优良的水泥基丙烯酸酯共聚型乳液的玻璃化温度最低为-13℃,丙烯酸酯乳液有玻璃化温度为-40℃的,可满足严寒地区使用要求,但丙烯酸酯乳液与EPS板的粘接性不好,故在冬季气温较低地区屋面EPS板缝隙上端第1遍应先涂刷具有强附着力的丙烯酸酯共聚型乳液配制的防水密封材料与EPS板粘接,EPS板是软泡可适应冬季防水密封材料收缩变形,但第2遍应涂刷满足玻璃化温度要求的丙烯酸酯乳液配制的防水密封材料,以适应温度变化和防水密封要求。Currently known cement-based acrylate copolymer emulsions with strong adhesion, water resistance and excellent durability have a minimum glass transition temperature of -13°C. Acrylic emulsions have a glass transition temperature of -40°C, which can be used in severe cold areas. Requirement, but the adhesion between acrylic emulsion and EPS board is not good. Therefore, in the area with low temperature in winter, the upper end of the roof EPS board gap should be painted with a waterproof sealing material formulated with a strong adhesive acrylic copolymer emulsion for the first time. Adhesive to the EPS board, the EPS board is a soft foam that can adapt to the shrinkage and deformation of the waterproof sealing material in winter, but the waterproof sealing material made of acrylic emulsion that meets the glass transition temperature should be painted in the second pass to adapt to temperature changes and waterproof sealing requirements .
第8条 缝隙填塞弹性防水密封材料称为嵌缝剂,如安装预制EPS窗台板和安装装饰线条与外墙之间的缝隙均需填塞嵌缝剂密封。市场上各种密封材料很多,只要满足防水密封和耐久性要求即可,或按本条配制嵌缝剂。配制嵌缝剂的乳液应满足玻璃化温度要求,将第7条粉体数量增加,搅拌混合均匀呈粘稠的膏状即为嵌缝剂,方便用抹子将其填塞到缝隙中起密封防水作用。相对位移较大缝隙应用硅烷改性聚醚胶即MS胶防水密封。
第9条 若在BFRP布上有水刷石、干粘石等装饰时,或粘贴饰面砖或抹水泥砂浆或抹保温砂浆(室内窗口侧面BFRP布上抹保温砂浆)时,选用水泥基丙烯酸酯共聚型乳液或水泥基丙烯酸酯乳液,乳液的玻璃化温度不应高于使用环境最低气温,可参照上述各条,灵活调整聚合物中乳液浓度涂刷到BFRP布上,再按规定进行水刷石、干粘石或安装饰面砖或抹灰等施工,需先做试验,试验成功后再大面积应用。
说明:1)乳液中加入粉体时加入分散剂、消泡剂,可避免水泥结球,避免起泡。Note: 1) Add dispersant and defoamer when adding powder to the emulsion to avoid cement balling and foaming.
2)在粘贴试验中,比较用不同胶粘剂原料、不同配合比配制出来胶粘剂,用于不同的粘贴部位,从中择优选择胶粘剂和配合比。2) In the pasting test, compare the adhesives formulated with different adhesive raw materials and different mixing ratios, which are used for different pasting parts, and the adhesives and mixing ratios are selected from the best.
3)对每批进场的胶粘剂原料都应提前试验检测,预制和施工中委托方和监理方可随机抽查检测。3) Each batch of adhesive raw materials that enter the site should be tested and tested in advance, and the entrusting party and supervisor can randomly check and test during prefabrication and construction.
4)以下检测乳液胶粘剂的简单方法使用方可自行检测:①延伸率检测:干燥后的膜片延伸率不小于8倍为宜。②将干燥后的膜片泡在水中48h后吸水率不大于8%为宜,膜片重量不应小于100g。4) The following simple methods for detecting emulsion adhesives can be used for self-testing: ① Elongation testing: The elongation of the dried film should not be less than 8 times. ② After soaking the dried film in water for 48 hours, the water absorption rate should not be more than 8%, and the weight of the film should not be less than 100g.
