Description

A heat-insulating broken bridge structure for door and window openings of composite thermal insulation wall

technical field

The invention relates to an opening structure of a door and window in a wall, in particular to a heat-insulating broken bridge structure of a door and window opening of a composite thermal insulation wall.

Background technique

The purpose of thermal insulation of energy-saving building envelopes is to limit the heat transfer between indoors and outdoors by taking thermal insulation measures for the envelopes, and reduce the energy consumption required for heating or cooling to ensure a comfortable indoor thermal environment. The exterior walls of buildings in heating areas are like our cotton coats, and the exterior walls of buildings in hot summer areas are like the shell of refrigerators. At present, energy-saving and thermal insulation walls are used to improve the thermal insulation effect of traditional walls and limit the heat transfer between indoors and outdoors by adding thermal insulation layers. However, the thermal bridge that has been difficult to eliminate for a long time has become the bottleneck of energy-saving wall technology.

1. The effect of the thermal bridge of the external wall pasted with EPS board thin plaster insulation wall on the thermal insulation performance of the wall:

At present, the thin plastered thermal insulation wall with EPS board (or XPS board) on the external wall is the wall technology with the best thermal insulation effect and the lowest price, so the thin plastered thermal insulation wall is most widely used in our country. But even the best thermal insulation EPS board thin plaster insulation wall has a lot of thermal bridges in the door and window openings: Figure 1 shows that when the doors and windows are installed in the middle of the base wall, the insulation layer of the side wall of the door and window opening is higher than that of the front wall. The layer thickness is much thinner, and the heat lost on the side of the opening is more in the front of the wall. Figure 2 shows that the doors and windows are installed at the outer corner of the base wall. The distance between the outer corner of the base wall and the outside is short, and the heat loss is also large at the corner of the hole. The length L of the arrow range in Figure 1 and Figure 2 is the thickness of the insulation layer at the thermal bridge.

The values of the thermal bridges in Figures 14 and 15 given in the "65% Design Standard for Energy Saving of Residential Buildings in Heilongjiang Province" are that when the thickness of the insulation layer is not greater than 120mm, there is a linear heat transfer coefficient ψ value in the opening of the thin plaster insulation wall For a thermal bridge of 0.1w/m.k, when the thickness of the insulation layer is not less than 120mm, the linear heat transfer coefficient ψ value of the hole reaches 0.11w/m.k! Due to the large number of openings in doors and windows, thermal bridges have a great influence, see the values in Attached Table 1.

Attached Table 1 Table of average heat transfer coefficient of EPS board thin plaster insulation wall, heat transfer coefficient unit: w/m ² .k

Note: 1. The values in Attached Table 1 are the average heat transfer coefficients of thinly plastered walls with EPS boards at different window-to-wall ratios and different EPS board thicknesses based on 0.2m concrete walls, 3.6m bays, and 2.8m story height.

2. The data in the table do not include the influence of thermal bridges of overhanging slabs such as balcony slabs on the average heat transfer coefficient of the wall.

The impact of thermal bridges at door and window openings on energy-saving and thermal insulation of walls can be illustrated with the following metaphor: thermal bridges at openings are like people’s necks or holes in the wall. If you don't wrap a wool scarf and don't block the holes, it is very difficult to make up for this heat loss by increasing the thickness of the cotton coat or the thickness of the insulation layer on the wall. But there is only one human neck, and there are many doors and windows in the building, so a lot of heat is lost at the opening. The thermal bridge at the opening has a great impact on building energy efficiency. The greater the window-to-wall ratio, the greater the impact. When a low heat transfer coefficient is required, it is very difficult to reduce the heat transfer coefficient by 0.1w/ ^m2 . The impact is too great.

In addition, a large number of cantilevered balcony panels and air-conditioning panels in the residence are still a large thermal bridge. Even if EPS panels with a thickness of 0.1m are pasted on the balcony panels, the linear heat transfer coefficient ψ value can reach 0.2w/mk. There are 100mm thick EPS boards above and below the cantilevered balcony slab for insulation. When the window-to-wall ratio is 0.3, the impact of the thermal bridge of the balcony slab on the average heat transfer coefficient of the wall is about 0.05w/m ² .k (assuming that the length of the balcony slab accounts for 40~ 50% calculation), EPS board thin plaster insulation wall opening thermal bridge and balcony plate thermal bridge total increase the average wall heat transfer coefficient of about 0.15 ~ 0.2w/m ² .k. Therefore, in order to meet the "65% Design Standard for Energy Saving of Residential Buildings in Heilongjiang Province", it is obtained that the heat transfer coefficient and the thickness of the insulation layer that should be achieved by the thin plaster insulation of the EPS board on the main wall are shown in Attached Table 2.

Attached Table 2 Residential buildings in severe cold (B) area Considering the linear heat transfer coefficient of the opening and the thermal bridge effect of the balcony plate, the heat transfer coefficient and the required thickness of the insulation layer for the main wall of the EPS board thin plaster insulation wall should be achieved

Note: 1. The main wall in Attached Table 2 is 0.2mm concrete wall, and the data includes the thermal bridge of the thermal insulation balcony slab (according to the length of the balcony slab accounting for 40-50% of the length of the outer wall, the window-to-wall ratio is 0.3, and the thermal bridge of the thermal insulation balcony slab and The effect of the thermal bridge at the opening on the average heat transfer coefficient of the wall is 0.15w/m ² .k; if the window-to-wall ratio is 0.5, the thermal bridge of the insulation balcony slab and the thermal bridge at the opening have an effect on the average heat transfer coefficient of the wall not less than 0.25w /m ² .k, the heat transfer coefficient that the main wall should achieve should be 0.1w/m ² .k smaller than the table, and it is impossible to achieve the goal of energy saving.

2. The limit value of the average heat transfer coefficient of the wall in the severe cold (A) area needs to be lowered by 0.05w/m ² .k than that in the (B) area, and the heat transfer coefficient that the main wall should reach is even more difficult to achieve.

It can be seen from Attached Table 1 and Attached Table 2 that when the average heat transfer coefficient of the wall is required to be no more than 0.4w/m ² .k for buildings below 8 floors, the benzene board insulation layer needs to be pasted because of the impact of the balcony board thermal bridge in the residence. The thickness is 0.2-0.3m, which not only increases the cost, but also wastes precious land resources. It is difficult to be accepted by investors, and it is hindered in practical application, which affects the realization of the national energy-saving and emission-reduction goals. At present, all wall energy-saving and thermal insulation technologies have not solved the problem of thermal bridges between doors and windows.

2. The thermal bridge of the steel wire grid cement sandwich panel insulation wall

In addition to the above-mentioned opening thermal bridge, the steel wire grid cement sandwich panel insulation wall also has 200 Φ2 steel wires per square meter to penetrate the insulation layer to increase heat transfer, which is 60% more heat transfer than EPS board thin plastered walls, and the heat transfer rate is 60%. Bridge more.

3. Thermal bridge of sandwich insulation wall

At present, a large number of sandwich insulation walls are used in Heilongjiang Province, and even high-rise buildings are also widely used. There is a thermal bridge of concrete cornice slabs along the perimeter of the building in the sandwich insulation wall, comparing the outer wall to cotton clothes, and each layer of the sandwich insulation wall has a belt that is not insulated—concrete cornice slabs. There are also thermal bridges around the opening, and the thermal bridges of the inner and outer leaf masonry tensioned steel bars. Fig. 3 shows the heat loss route (shown by the curve) at the thermal bridge of the cornice plate of the sandwich insulation wall pasted with insulation strips at the thermal bridge of the cornice plate. However, even if thermal insulation strips are pasted on the outer end of the thermal bridge of the cornice plate as shown in Figure 3, because the extended thermal bridge route is very small, the improvement of thermal insulation is almost useless. Comparing with the linear heat transfer coefficient value of the 120mm-thick balcony cantilever slab without insulation in the "65% Design Standard for Energy Saving of Residential Buildings in Heilongjiang Province", assuming the thickness of the eaves slab is 80mm, the linear heat transfer coefficient of the eaves slab thermal bridge is about 0.43w/ mk. The influence of thermal bridges on the average heat transfer coefficient in a 2.8m-story building is analyzed. According to the window-to-wall ratio of 0.3, the thickness of the EPS board on the upper and lower insulation layers of the balcony slab, and the thermal bridge of the cornice board on the sandwich insulation wall, the average heat transfer of the wall is increased. The coefficient is about 0.15～0.2w/m ² .k, plus the thermal bridge around the opening (too unsafe to calculate, it is still estimated according to the linear heat transfer coefficient of the thermal bridge of the opening with EPS board and thin plastering), and the total increase in the wall The average heat transfer coefficient is about 0.25～0.3w/m ² .k! (However, when the window-to-wall ratio is 0.5, the average heat transfer coefficient of the wall is increased by about 0.35w/m ² .k! Since it is more difficult to achieve, the value in the attached table 3 has already explained the problem, so this value will not be taken) According to "Heilongjiang Province Residential According to the limit value of the average heat transfer coefficient of the wall in the severe cold (B) area specified in the residential building energy-saving design judgment table in "Design Standard for 65% Building Energy Saving", the approximate heat transfer coefficient that should be achieved by the sandwich insulation of the main wall can be obtained, see Schedule 3.

Attached Table 3 Considering the impact of the linear heat transfer coefficient of the opening and the cornice board for residential buildings in severe cold (B), the heat transfer coefficient and the required thickness of the insulation layer for the main wall with core insulation should be achieved

Note: 1. Attached Table 3 assumes that the concrete wall is 0.2m thick, the bay is 3.6m, and the storey height is 2.8m. According to the window-to-wall ratio of 0.3, the data includes the average heat transfer coefficient of the thermal bridge of the insulation balcony plate and the thermal bridge of the opening to the wall. Impact.

2. The limit value of the average heat transfer coefficient of the wall in the severe cold area (A) needs to be lowered by 0.05w/m ² than that in the area (B), which is even more difficult to achieve.

However, the thermal bridge at the opening of the sandwich insulation wall should be much larger than the thermal bridge at the opening of the EPS board thin plaster insulation wall. Even the heat transfer coefficient that should be achieved by the main wall in the appendix 3 cannot be satisfied. Then consider the sandwich insulation It is also meaningless that the thermal bridge of the opening of the wall is increased by the thermal bridge of the opening of the thin plaster. According to GB50003 "Code for Design of Masonry Structures", the thickness of the middle insulation layer of sandwich insulation should not be greater than 100mm, so it is impossible to meet the requirements of the limit value of the average heat transfer coefficient of the wall.

4. Insulation block wall

The thermal bridge of the thermal insulation block wall at the cornice board and the opening is close to the thermal bridge of the sandwich thermal insulation wall, but there are still the following problems: the thermal insulation block wall is fragmented by sand, slag, ceramsite, cement, etc. , from the analysis of the purpose of blocking heat transfer, its structure is unreasonable. How thick is the insulation block wall of the main wall in severe cold regions to meet the requirements of the average heat transfer coefficient of the wall in Appendix 2? If the insulation effect of EPS boards and XPS boards is compared to cotton or down, then some materials with high thermal conductivity can be compared to old cotton or catkins, and insulation blocks can be compared to down or cotton mixed with slag, sand, and cement. wall or material.

5. Inner insulation wall

There are floor thermal bridges along the perimeter of the building and thermal bridges at the opening of the inner thermal insulation wall. The thickness of the floor must be greater than the thickness of the eaves. There are also indoor partition wall thermal bridges. The thickness of the indoor partition wall masonry in multi-storey buildings is 0.37m, 0.24m m, the concrete wall of a high-rise building with a thickness of about 0.2-0.3m. There are a large number of non-insulated interior partition walls in the inner insulation wall - it seems that only the cloth is connected between the front and back of the cotton jacket, but there is no cotton near the seam to become a thermal bridge to penetrate the cold. The influence of the heat bridge of the inner insulation wall is far greater than that of the heat bridge of the sandwich insulation wall! In Appendix C of JGJ26-95 "Energy Saving Design Standards for Civil Buildings", it is pointed out that under the condition of internal heat preservation, the thermal bridges around concrete beams and columns increase the average heat transfer coefficient of the wall by 51-59%. Unfortunately, North China A large number of internal insulation buildings have been built in the area.

6. Prefabricated insulation wall panels

Prefabricated wall panels not only have hole thermal bridges, but also joint thermal bridges. The joint thermal bridges have a great influence on the average heat transfer coefficient of the wall. Engineering examples of long hairs already exist.

The sandwich insulation wall (EPS board 100mm), the steel wire grid insulation wall (EPS board 100mm), the 300mm thick insulation block wall and the inner insulation wall designed according to the energy saving of 50% cannot meet the requirements of residential buildings. The average heat transfer does not exceed the requirements of energy-saving walls below 0.75w/m ² .k. During the heating season of 2003 to 2005, the Research Institute of the Chinese Academy of Building Research conducted continuous tests on some energy-saving buildings in Beijing and found that buildings built according to the energy-saving standard of 50% achieved energy-saving results of 37%, and buildings with energy-saving energy of 30% actually only saved 7%! Now some regions in China have begun to try out the energy-saving 65% standard, and the above-mentioned walls with more thermal bridges affect the realization of this energy-saving goal. This is not only the case in China, some countries in the world are also adopting internal insulation or sandwich insulation wall technology.

More thermal bridges increase the difficulty of architects' design calculations, and because they are worried that these walls with more thermal bridges will have high heat transfer and fail to meet the heating requirements, thermal engineering design engineers have to estimate more heat consumption of the walls. How can energy saving goals be achieved? Housing thermal bridges have a great impact on the construction of a low-carbon society and the sustainable development of society, with serious sequelae.

The applicant of this patent has filed the following patent applications in China regarding the wall technology: 1. The name of the invention is "Seismic and thermal insulation composite wall with support and reinforced concrete outer protective layer", the patent number is 200410002698.7; 2. The name of the invention is "With Supported bundled composite thermal insulation wall", the patent number is 200610153289.6; 3. The invention name is "composite wall with steel bars/and metal mesh plastering on both sides", the patent application number is 200710167871.2, and the publication number is CN101168977; 4 , The name of the invention is "A Composite Component for Alkali-Resistant Glass Fiber Mesh Plastering", the patent application number is 200910141007.4, and the publication number is CN101570981.

In the disclosed No. 1 and No. 2 patents of the present patent applicant, the following reasons lead to the thermal bridge of the opening of the composite wall of the above two patents being greater than the impact of the thermal bridge of the opening of the EPS board thinly plastered wall: 1. When the doors and windows are installed on the base wall, even if the insulation strip is pasted on the outside of the door and window profiles, there is a plastering protective layer of 30mm on the insulation strip. Due to the size limit of the window profile, the thickness of the insulation strip is 15mm less than the side of the opening of the EPS board thin plastered wall. The thickness of the insulation strip is 30mm, so the opening thermal bridge of the above two patent composite walls is larger than the opening thermal bridge of the EPS board thinly plastered wall. 2. When the doors and windows are installed on the concrete components of the opening, the opening and the connecting steel parts pass through the insulation layer, which increases the heat transfer of the opening. Supported bundled composite thermal insulation walls are equipped with supporting cantilever beams, which can reduce the thermal bridge of concrete cornice boards along the perimeter of the building by 90% compared with sandwich thermal insulation walls, making its thermal insulation effect far better than that of sandwich thermal insulation walls Body and thermal insulation block wall, but because the thermal bridge in the door and window openings is larger than the thin plaster thermal bridge, the thermal insulation effect is lower than that of the EPS board thin plaster thermal insulation wall.

In the No. 3 patent of the present patent applicant whose background technology has been disclosed, the structure in the first embodiment is "there is an opening protective layer 16 at the opening of the door and window, and the door and window are fixed on the opening protective layer 16"; in the fourth patent, The structure in the first embodiment is "...the surface of the core layer 3 has a protective layer 8," see the accompanying drawings of these two patents, the windows of these two patent drawings are all installed on the cement mortar plastering layer at the entrance . In order to ensure the thickness of the reinforced protective layer at the opening, the thickness of the cement mortar plastering layer at the opening generally needs to be 30mm, and the thermal bridge at the opening is also larger than the thermal bridge at the opening of the thinly plastered wall of the EPS board. The linear heat transfer coefficient of the thermal bridge at the opening is about 0.15w/m.k. It is unfavorable to energy-saving and thermal insulation of the wall.

There is a protective layer on the inner side of the door and window and an outer protective layer on the outer side of the door and window, forming a thermal insulation bridge structure for the opening of the door and window of the composite thermal insulation wall.

Technical effect of the present invention:

In the first to fourth structures of a thermally insulating broken bridge of a door and window opening of a composite thermal insulation wall of the present invention, "...the outer protective layer of the door and window, and the inner protective layer of the door and window are protective layers with thermal insulation effect" means Paste EPS board thin plaster insulation strips or insulation mortar or rubber powder polystyrene particles on both sides of the door and window profiles of the opening or only on the inside and outside as a protective layer. The surface of the particles is pasted with alkali-resistant mesh cloth as a reinforcement layer, so it can be used as a protective layer for doors and windows, and has the function of heat preservation. The protective layer on the inner side of the door and window room is a protective layer with thermal insulation effect, and thermal insulation mortar should be used to increase fire safety. The outer protective layer of doors and windows and the inner protective layer of doors and windows are protective layers with thermal insulation effect, which can play two roles: 1. Further prolong the distance between the indoor protective layer or the base wall and the outdoor, and reduce the thermal bridge of the opening; 2. Prevent doors and windows The profiles condense on the interior side and improve the insulation of doors and windows. As long as the thermal resistance of the distance L+a between the outdoor cold spot of the door and window profile and the outer corner of the indoor protective layer or the base wall is not less than the thermal resistance of the main wall, the linear heat transfer coefficient of the opening is "0", that is, the heat transfer around the opening is no higher than that of the main wall. There are many main walls. Figure 6, Figure 8, Figure 11, Figure 13, Figure 16, Figure 18, Figure 19, Figure 22, and Figure 24. The design value of the thermal conductivity of the EPS board is 0.05w/m.k, and the outer protective layer of doors and windows is a protective layer with thermal insulation effect, such as the protective layer of thin plastered thin strips of EPS board or polyurethane thin plastered thin strips of thermal insulation on the outer side of the door and window profiles , the linear heat transfer coefficient of the hole can reach "0". When the insulation layer around the opening is made of thermal insulation mortar or rubber powder polystyrene particles (the thermal conductivity is about 0.07w/m.k), or even when the plaster on the outside of the door and window is cement mortar, the effect of thermal insulation and bridge breaking is slightly poor, and the linear heat transfer of the opening cannot be achieved. The coefficient is "0". When the insulation layer around the opening is thermal insulation mortar or rubber powder polystyrene particles, and the outer protective layer of doors and windows is a protective layer with thermal insulation effect, the thermal bridge at the opening can be reduced by about 60-80%. Figure 7, Figure 12, Figure 15, Figure 17, Figure 21, Figure 23 The external protective layer of doors and windows is cement mortar, the thermal resistance of the cement mortar protective layer is extremely small, its essence is a=0, but the doors and windows are installed on the insulation layer of the opening There is still the effect of heat insulation bridge break, but the effect of heat insulation bridge break is weakened. In order to avoid condensation on indoor windows, the outer protective layer of doors and windows in severe cold areas should not be cement mortar, but should be a protective layer with thermal insulation effect. Figure 9, Figure 18, Figure 19, and Figure 24 show that when there is an indoor base wall, a part of the insulation layer is added on the base wall, and the windows are installed on the insulation layer corresponding to the indoor protective layer. The thermal resistance of the protective layer passing through the insulation layer of the side wall of the opening to the outdoor cold spot should not be less than the thermal resistance of the main wall, and the linear heat transfer coefficient of the thermal bridge of the opening is "0", so the insulation layer of the side wall of the opening needs to be very thick. It is not convenient for construction unless it is used when necessary.

When using mineral wool as the insulation layer for door and window openings, wrap the mineral wool board with plastic film or plastic composite film. During construction, brush polyacrylate elastic emulsion adhesive on plastic film or plastic composite film to wrap mineral wool board, and brush polyacrylate elastic emulsion adhesive on insulation layer EPS board, and wrap mineral wool board with plastic film or plastic composite film. The board is pasted on the insulation layer, and the plastic film or plastic composite film is coated with polyacrylate elastic emulsion adhesive, and the modified cement mortar plastering protective layer on the side of the hole can be bonded with the polyacrylate elastic emulsion; on the plastic film Or brush the polyacrylate elastic emulsion adhesive on the plastic composite film, the alkali-resistant mesh can be pasted with the plastic film, and the alkali-resistant mesh can be connected with the outdoor protective layer and the indoor protective layer or the base wall.

The plastic film is polyester film and polyester aluminum foil plastic composite film, polyacrylic acid elastic emulsion with low glass transition temperature (-5 degrees to -40 degrees, depending on the minimum temperature of the project location, choose polyacrylic acid with different glass transition temperature Lipoelastic emulsion) is soft after film formation after drying, firmly adhered to plastic film, convenient for brushing and construction, environmentally friendly and non-toxic. It can be pasted with the EPS board of the insulation layer by directly painting the original slurry of the polyacrylate emulsion, which saves labor and uses a small amount of adhesive, which is cheap and has good air-proof and waterproof effects. The two sides of the alkali-resistant mesh and the indoor and outdoor plastering protective layer can be pasted with cement polymer mortar.

The present invention can reduce the heat transfer heat loss around the opening of the door and window through the reasonable structure of the opening of the door and window, which is like wearing a woolen scarf around the neck. The comparison of the average heat transfer coefficient of the composite wall with the heat-insulating broken bridge structure of the door and window openings of the present invention and the composite wall with thermal bridges in the openings of the original patent is shown in Attached Table 4. It can be seen from the attached table 4 that when the thickness of the EPS board is 150mm and the window-to-wall ratio is 0.36, the average heat transfer coefficient of the wall including the thermal bridge of the balcony board is about 0.33+0.05=0.38w/m ² .k, making 8 It is possible to save energy by 65% below the floor. Comparing the data in Table 4 with Table 2, it can be seen that the energy-saving and heat-preservation effect of the "supported bundled composite heat-insulation wall" of the thermal insulation bridge at the entrance is far better than that of the thin-plastered heat-insulation wall. The composite wall of the patent "A Composite Component with Alkali-Resistant Glass Fiber Mesh Plastering" adopts the heat insulation bridge structure of the door and window openings of the present invention and the comparison of the average heat transfer coefficient of the composite wall when the openings of the original patent have thermal bridges is shown in the attached table. 5. It can be seen from the attached table 5 that the thickness of the EPS board is 0.2m, and the total thickness of the composite thermal insulation wall of "a composite member plastered with alkali-resistant glass fiber mesh" is 0.26mm, including the influence of the thermal bridge of the balcony board, and the thermal insulation bridge structure of the opening The average heat transfer coefficient of the composite wall residential building can reach about 0.26+0.05=0.31w/m ² .k low heat transfer coefficient; when the thickness of the EPS board is 0.3m, and the total thickness of the composite insulation wall is 0.36mm, it can reach 0.18+ Low heat transfer coefficient of 0.05=0.23w/m ² .k. A composite wall with a total thickness of 0.26 to 0.36m is a wall thickness that makes people feel comfortable, and the composite thermal insulation wall of the building energy-saving "composite component of alkali-resistant glass fiber mesh plastering" adopts the opening heat insulation of the present invention. The structure of the bridge really becomes an energy-saving and land-saving wall.

Our country and many countries in the world do not have the conditions to build Nordic wooden structures filled with mineral wool with a thickness of 40-50 cm. We also do not have the conditions to build external walls with three-layer walls sandwiched by double-layer benzene panels like Russia. However, concrete or various This kind of masonry is the base wall and the external thermal insulation wall adopts the opening heat insulation broken bridge structure, which has the conditions to achieve the energy saving level of the low heat transfer coefficient of the Nordic wall.

When the thermal bridge effect of the opening does not exist, it is very simple to design and calculate the average heat transfer coefficient of the wall.

The heat transfer coefficient unit: w/m ^2.k

Note: 1. Attached Table 4 assumes that the concrete wall is 0.2m thick, the bay is 3.6m, the storey height is 2.8m, and there are 3 supporting cantilever beams supporting the wall, area = bh = 0.1×0.12 = 0.1×0.12×3 =0.036m ^{2 .} , the average heat transfer coefficient of the wall at different window-to-wall ratios and different EPS board thicknesses.

To sum up, the technical effect of the present invention is that a composite thermal insulation wall door and window opening heat insulation broken bridge structure of the present invention can greatly reduce or eliminate the heat transfer increased by the thermal bridge at the opening, and minimize the loss of building heat. It is of great significance to building energy saving and emission reduction, and building low-carbon buildings.

In order to save energy in buildings and cancel clay bricks, the Chinese government has invested a lot of money in the development of new wall materials for many years, but it has not solved the bottleneck of wall technology well. This is because the properties of various new wall materials have their limitations. For example, polyurethane insulation is the best, but it cannot solve the problem of thermal insulation and broken bridges at openings. For example, the thermal insulation performance of new wall materials such as thermal insulation block walls, steel wire grid cement sandwich panel walls, and the energy-saving thermal insulation performance of thin plastered thermal insulation walls pasted with EPS boards is too much worse! Its thermal insulation performance is even more incomparable with that of the supported external insulation composite insulation wall of the opening insulation bridge. What is the energy saving rate of this type of building that has already been constructed?

It is estimated that 60% of carbon dioxide emissions in cities come from the energy consumed to maintain building functions, while traffic vehicles only account for about 30%, and energy-saving technology for exterior walls and windows is the primary technical condition for building low-carbon buildings . In the wall energy-saving technology, only by greatly reducing the heat bridge of the energy-saving and heat-insulating wall and reducing the passage of heat loss, can the building energy saving really achieve the expected effect. ~45% guaranteed.

Low-energy buildings should adopt heat-insulating broken bridge structures. At present, the most widely used insulation layer is a material with low thermal conductivity and low price, such as polymer insulation material EPS board. The thermal insulation layer in the composite wall can be one type of thermal insulation material, or different thermal insulation materials: when the thermal insulation layer of the wall is a polymer thermal insulation material with poor fire resistance, the local thermal insulation layer around the opening should use a thermal insulation material with good fire resistance , such as mineral wool, thermal insulation mortar, rubber powder polystyrene particle thermal insulation slurry. Also for example, the core layer on the outside of the main structure of the building can be sprayed with polyurethane foam for heat preservation, while the inside of the frame opening can be an EPS board. Figures 6 to 8 show that the insulation layer of the opening is rock wool, and the protective layer on the outside of the doors and windows of the opening in Figures 6 and 8 is the protective layer pasted with EPS board thin plaster insulation strips, and the effect of thermal insulation is the best. Figures 6 and 8 When the thermal resistance of the L+a length section marked in 8 is not less than the thermal resistance of the main wall, the linear heat transfer coefficient of the opening is "0"; but Figure 5 shows that the insulation layer of the opening is insulation mortar or rubber powder polystyrene particles. The thermal conductivity of thermal insulation mortar and rubber powder polystyrene particle thermal insulation slurry is about 0.07~0.08w/m.k, and the linear heat transfer coefficient of the hole is about 0.03~0.04w/m.k, which can reduce the thermal bridge of the hole by 60~70%, which is also very considerable of.

When mineral wool is used for insulation at the opening, since mineral wool is easy to absorb moisture and collapse and deform, plastic film or plastic composite film should be used to wrap mineral wool. The most effective and cheap material for mineral wool waterproof and moisture-proof layer is polyester sandwich aluminum foil (PET//AL//PET) plastic composite film, because of the aluminum foil layer, the water vapor penetration resistance is very large. The waterproof and moisture-proof layer 15 described in this embodiment is pasted on the surface of the hole insulation layer 3, and also includes the waterproof and moisture-proof layer 15 wrapping the insulation layer around the hole. When the hole insulation layer is mineral wool in Figs. , all mean that the mineral wool is wrapped by a waterproof and moisture-proof layer, but if the moisture-proof layer has been set up indoors, no water vapor will seep out, and the polyester laminated aluminum foil plastic composite film can also be pasted on the upper part of the mineral wool for waterproofing, without wrapping. But now there is rainy weather in the heating area in summer, so the mineral wool may be damp. Therefore, when the opening is a mineral wool insulation layer, it is best to wrap the mineral wool with an air barrier layer.

Specific embodiment two: see Fig. 4～Fig. 8, the difference between this embodiment and specific embodiment one is, this embodiment adds alkali-resistant mesh cloth 5-1; Said alkali-resistant mesh cloth 5-1 is pasted on the opening of the hole for heat preservation On the surface of layer 3, doors and windows 20 are installed on the alkali-resistant mesh cloth 5-1 of the hole, and the alkali-resistant mesh cloth 5-1 is lapped and pasted with the indoor protective layer 8-1 and the outdoor protective layer 8-2.

Alkali-resistant mesh is the abbreviation for alkali-resistant glass fiber mesh in the JCT-841-2007 standard of "Alkali-resistant Glass Fiber Mesh". The strength retention rate of alkali-resistant mesh in strong alkali ordinary Portland cement can not be less than 80%, and the alkali-resistant mesh has considerable tensile capacity. The GRC wallboard added with alkali-resistant chopped glass fiber has been used abroad since the 1970s. At present, there are engineering examples that are still in use for nearly 30 years. Multiply the strength retention value of the alkali-resistant mesh by a certain safety reserve factor as the design value of the tensile strength of the alkali-resistant mesh, and then design and calculate it by referring to steel bars and steel wire mesh, and set the alkali-resistant mesh to connect the inside and outside of the hole. The metal mesh is connected to reduce heat transfer, easy to install, and the metal mesh is easy to corrode. The alkali-resistant mesh cloth can be plastered with cement polymer mortar or glue, but it will increase the heat transfer of the hole (cement and sand both increase heat transfer), and it can also be pasted directly with a water-soluble adhesive, but it will not be compatible with the indoor protective layer on both sides of the hole. And the outdoor protective layer can be pasted with cement polymer mortar. Embodiment 5 holes are also pasted with alkali-resistant mesh according to this, but the indoor side is pasted with the base wall.

The alkali mesh cloth 5-1 is pasted on the surface of the waterproof and moisture-proof layer 15, and the door and window 20 are installed on the alkali-resistant mesh cloth 5-1 at the opening; Then paste the connection.

The key location for waterproofing of door and window openings is the window sill, but it is more beneficial to install waterproof and moisture-proof layers around the openings. Specifically, the setting range of waterproof and moisture-proof layers for door and window openings should be determined according to the different types of insulation layer materials around the openings. Polymer waterproof membrane such as polyethylene polypropylene fiber composite waterproof membrane, or PVC waterproof membrane. Ordinary cement mortar is plastered on plastic film or polymer waterproof membrane, and it needs to be plastered with interface agent prepared by adhesive, which can be bonded with waterproof and moisture-proof layer.
