技术领域technical field
本发明属于建筑技术领域，特别涉及一种基于砂浆外保温处理的装配式复合墙板。The invention belongs to the technical field of construction, and in particular relates to an assembled composite wallboard based on mortar external heat preservation treatment.
背景技术Background technique
在我国新型城镇化进程不断推进的背景下,建筑物能耗量在社会的总能耗量中所占的比例不断上升，已经严重制约了经济的发展，建造更经济实惠、节能环保、可持续发展的住宅，是提高我国城镇化水平的重要有效措施，因此建筑节能刻不容缓，而外墙节能对整个建筑物的耗能量起着支配性作用。装配式混凝土节能与结构一体化符合我国“十二五”规划中提出的资源节约、环境友好的社会要求，是实现建筑节能减排及住宅产业化的有效途径之一。目前传统的外墙保温的发展面临诸多问题，一方面承重墙体与保温系统并未完全一体化施工，传统外墙外保温系统通过粘贴式或机械固定在外墙主体结构上，系统受力复杂，施工工艺较复杂，需要二次施工，成本较高，工程质量也难以控制。另一方面目前我国住宅建筑的外墙外保温材料主要使用发泡聚苯乙烯(EPS)或挤塑聚苯乙烯((XPS)等有机材料，这些材料普遍具有价格较高、易燃、易老化、耐久性差等问题，且一旦燃烧就会释放出有毒气体，危害人体健康，造成环境污染。同时墙体所用的材料为传统混凝土材料，使得我国的能源和原材料消耗过大，因此寻找新型生态混凝土墙体材料已成为现在亟需解决的问题。最后，传统装配式剪力墙结构整体性差，连接方式需要进一步改进。In the context of the continuous advancement of my country's new urbanization process, the proportion of building energy consumption in the total energy consumption of society has been rising, which has seriously restricted economic development. Construction is more economical, energy-saving, environmentally friendly, and sustainable. The development of residential buildings is an important and effective measure to improve the level of urbanization in our country, so building energy conservation is urgent, and exterior wall energy conservation plays a dominant role in the energy consumption of the entire building. The energy-saving and structural integration of prefabricated concrete conforms to the social requirements of resource conservation and environmental friendliness put forward in my country's "Twelfth Five-Year Plan", and is one of the effective ways to realize building energy-saving emission reduction and housing industrialization. At present, the development of traditional external wall insulation faces many problems. On the one hand, the load-bearing wall and thermal insulation system are not fully integrated. The traditional external wall thermal insulation system is fixed on the main structure of the external wall by sticking or mechanically. The force of the system is complicated. The construction process is relatively complicated, requiring secondary construction, the cost is high, and the quality of the project is difficult to control. On the other hand, organic materials such as expanded polystyrene (EPS) or extruded polystyrene (XPS) are mainly used as external thermal insulation materials for residential buildings in my country. These materials generally have high prices, are flammable, and are easy to age , poor durability and other issues, and once burned, it will release toxic gas, which will endanger human health and cause environmental pollution. At the same time, the material used for the wall is traditional concrete material, which makes our country consume too much energy and raw materials. Therefore, we are looking for a new type of ecological concrete. Wall materials have become an urgent problem to be solved. Finally, the structural integrity of traditional prefabricated shear walls is poor, and the connection method needs to be further improved.

如图2所示，复合墙板1以截面和配筋较小的钢筋混凝土框格，内嵌以工农业废料为主的生态块材组成，在竖向及水平荷载作用下，复合墙板中的钢筋混凝土框格与填充体两两相互作用、相互约束、共同受力，充分发挥各自性能；同时，内填墙体材料，因地制宜、就地取材、生态节能。墙板侧面做成马牙槎，墙板水平方向主要是通过马牙槎与后浇竖向边缘构件紧密咬合连接，水平钢筋预留足够的锚固长度与边缘构件纵筋嵌套，并在连接处一一点焊实现可靠锚固。竖向接方式为底部坐浆连接，铺设砂浆厚度均匀，墙板安装后灰缝应填塞密实，填塞后的灰缝应表面光洁平整。As shown in Figure 2, the composite wall panel 1 is composed of a reinforced concrete frame with small cross-section and reinforcement, embedded with ecological blocks mainly made of industrial and agricultural waste. Under the action of vertical and horizontal loads, the composite wall panel The reinforced concrete sash and the filling body interact in pairs, constrain each other, and bear force together to give full play to their respective performances; at the same time, the inner wall material is adapted to local conditions, local materials, ecological and energy-saving. The side of the wall panel is made of horse teeth. The horizontal direction of the wall panel is mainly connected closely with the post-cast vertical edge members through the horse teeth. One point welding to achieve reliable anchoring. The vertical connection method is the bottom sitting grout connection, and the laying mortar thickness is uniform. After the wallboard is installed, the mortar joints should be filled tightly, and the filled mortar joints should have a smooth and smooth surface.
本发明装配式复合墙板的制备包括如下步骤：The preparation of the assembled composite wallboard of the present invention comprises the following steps:
步骤一：复合墙板1的制备：Step 1: Preparation of Composite Wallboard 1:
首先组装马牙槎专用钢模板，绑扎肋格钢筋网片，在网片内放置生态块材11，以生态块材11为内膜，钢模板为外膜，用混凝土浇筑肋梁12、肋柱13，最后标准养护1～2d，形成带马牙槎的新型复合墙板。First assemble the special steel formwork for Ma Yacha, bind the ribbed steel mesh, place the ecological block 11 in the mesh, use the ecological block 11 as the inner membrane, and the steel formwork as the outer membrane, and pour the rib beam 12 and the rib column with concrete 13. The final standard maintenance is 1-2 days to form a new type of composite wallboard with horse teeth.
步骤二：保温砂浆3的制备：Step 2: Preparation of thermal insulation mortar 3:
保温砂浆3采用EPS颗粒和玻化微珠复合保温砂浆，保温砂浆3的最优配合比为水：水泥：EPS颗粒：玻化微珠：硫酸钙晶须：胶粉：纤维素醚＝1.04kg：1kg:3.5L:2.25L:9g:15g:6g。保温砂浆的制作方法如下：首先将硫酸钙晶须和保温骨料混合搅拌使得硫酸钙晶须分散在保温骨料中；再将外加剂和水泥与硫酸钙晶须和保温骨料的混合物混合，先干搅拌再加水搅拌；搅拌时间与普通混凝土一致；最后取得保温砂浆3。Insulation mortar 3 adopts composite insulation mortar made of EPS particles and vitrified microspheres, and the optimal mix ratio of insulation mortar 3 is water: cement: EPS particles: vitrified microspheres: calcium sulfate whiskers: rubber powder: cellulose ether = 1.04kg : 1kg:3.5L:2.25L:9g:15g:6g. The production method of the thermal insulation mortar is as follows: first, mix and stir the calcium sulfate whiskers and the thermal insulation aggregate to disperse the calcium sulfate whiskers in the thermal insulation aggregate; then mix the admixture and cement with the mixture of the calcium sulfate whiskers and the thermal insulation aggregate, First dry mixing and then water mixing; the mixing time is the same as that of ordinary concrete; finally get the thermal insulation mortar 3.
步骤三：保温层施工：Step 3: Insulation layer construction:
在生产好的复合墙板1上，首先涂抹10mm厚聚合物粘结砂浆2，然后喷涂或浇筑35mm厚保温砂浆3，平整后，静停两个小时，再涂抹10mm聚合物抗裂砂浆4，最后把耐碱玻璃网格布5压入聚合物抗裂砂浆4，即可形成带马牙槎连接的砂浆外保温处理的装配式复合墙板。On the produced composite wallboard 1, first apply 10mm thick polymer bonding mortar 2, then spray or pour 35mm thick thermal insulation mortar 3, after leveling, stop for two hours, and then apply 10mm polymer anti-cracking mortar 4, Finally, the alkali-resistant glass grid cloth 5 is pressed into the polymer anti-cracking mortar 4 to form a prefabricated composite wallboard with mortar external heat preservation treatment with horse-tooth connection.
