Description

External wall thermal insulation composite wall with support

The invention relates to an external thermal insulation composite wall of a building. Background technique

The purpose of heat preservation of the energy-saving building envelope is to limit the heat transfer between the indoor and outdoor through the insulation measures of the envelope structure, and reduce the energy consumption required to ensure the heating or cooling of the indoor comfortable warm environment. The exterior wall of a building in a heating area is like our cotton coat. The outer wall of a building in a hot summer area is like the outer casing of a refrigerator. At present, the energy-saving insulation wall is to improve the insulation effect of the traditional wall by adding the insulation layer, and to limit the heat transfer between the indoor and outdoor. However, the heat bridge which has been difficult to eliminate for a long time has become a bottleneck for energy saving of the barrier wall.

1. The advantages and disadvantages of current various energy-saving thermal insulation composite walls and the effect of thermal bridges on wall insulation performance:

1. Analysis of exterior wall paste EPS board thin plaster insulation wall:

At present, the external wall paste EPS board (or XPS board) thin plaster insulation wall is the best insulation effect, the lowest price of the insulation wall, so the EPS board thin plaster insulation wall is the most widely used in China. However, even the best insulated EPS board thin plastering insulation wall also has a thermal bridge at the door and window opening: Figure 8 shows that when the door and window are installed in the middle of the base wall, the insulation layer of the side wall of the door and window is thin, and the insulation is not good; 10 shows that the doors and windows are installed at the outer corner of the base wall. The outer corner of the base wall is shorter than the outdoor distance, and the insulation of the door and window openings is not good. The length L of the arrow range in Fig. 8 and Fig. 10 is the thickness of the thermal insulation layer.

The value of the thermal bridge of Figure 8 and Figure 10 is given in the “Design Standard for Energy Efficiency of Residential Buildings in Heilongjiang Province”. The thermal bridge with a linear heat transfer coefficient of 0.1w/mk exists in the hole of the thin plaster insulation wall! Due to the large number of door and window openings, the thermal bridge has a great influence. The average heat transfer coefficient of the wall is about 0.1 w/m ² .k ! The larger the window-to-wall ratio is, the more the thermal bridge is affected. Big. The heat bridge of the door and window hole is like a human neck. The weather is particularly cold, and the neck must be surrounded by a woolen scarf. However, there is only one person's neck, and the number of doors and windows in the building is very large. Therefore, when the indoor and outdoor temperature difference in the heating area is large, the heat bridge of the door and window opening has a great influence on the building energy saving.

A large number of cantilevered balcony panels and air-conditioning panels in the house are also a large thermal bridge. Even if the EPS board with a thickness of 100mm is attached to all the panels on the balcony, the linear heat transfer coefficient is 0.2w/mk. There is 100mm thick EPS board insulation on the cantilevered balcony. When the window and wall ratio is 0.3, the effect of the balcony bridge thermal bridge on the average heat transfer coefficient of the wall is about 0.05w/m ² .k (according to the length of the balcony board, the length of the external wall is 40~) 50% calculation), EPS board thin plastering insulation wall hole thermal bridge and balcony plate thermal bridge total increase of wall average heat transfer coefficient of about 0.15w / m ² .k _; window wall than 0.5 when the increase of wall average transmission The thermal coefficient is 0.23 w/m ² .lc ! Thus, according to the ratio of window to wall ratio of 0.3, it is found that the design standard of “65% energy saving of residential buildings in Heilongjiang Province” is satisfied, and the thin plastering insulation of the main wall EPS board is obtained. The heat transfer coefficient and the required insulation thickness are shown in Table 1. It can be seen from the attached Table 1 that it is too difficult to achieve the specified heat transfer coefficient for the building energy-saving wall below 8 floors. If the heat bridge at the hole is reduced, the difference between the heat transfer coefficient of the main wall and the average heat transfer coefficient of the wall is reduced. Energy-saving The label is easier to implement, which is one of the important purposes of the present invention.

Schedule 1 Severe cold (B) residential building considering the influence of linear heat transfer coefficient, the heat transfer coefficient of the main wall of the EPS board thin plastering and the required thickness of the insulation layer

Note: 1. The data of Schedule 1 is influenced by the window-wall ratio of 0.3, including the thermal bridge of the thermal insulation balcony, the thermal bridge of the portal, and the thermal bridge of the cantilever beam to the average heat transfer coefficient of the wall.

2. The average heat transfer coefficient limit ratio of the wall in severe cold (A) area is also reduced by 0.05w/m ² .k. The heat transfer coefficient of the main wall should be more difficult to achieve.

If the balcony is not insulated, the average heat transfer coefficient of the wall is increased by about 0.1 w/m ² .k !

However, the thin plastering insulation wall also has the following serious problems:

1), the fire is not safe, and the outer surface is not safe.

The thin plastered insulation wall has poor fire protection and unsafe outer surface. In Germany, rock wool is used as a fire barrier in the door window and every two layers, and the rock wool insulation is used for buildings over 20m. The quality of rock wool in China is not good, there is no fire isolation measures, because the thin plastering insulation wall is low in cost. Insulation is good, and our country, including high-rise buildings, is being used in large quantities. Thin plastered exterior insulation systems are banned in the United States due to serious fire protection problems; buildings over 18 meters in the UK are not allowed; in Germany, buildings over 22 meters are not allowed.

2), poor durability, large maintenance.

The bismuth molecular adhesive and glass fiber mesh in the polymer mortar affect the durability of the outdoor environment in the harsh environment of ultraviolet rays and wind and rain. In Germany, the thin plaster insulation wall attached in the 1970s has been repaired, and the thin plaster protection layer is removed. The original EPS board is pasted with 100mm EPS board insulation. In China, a large number of projects have low effective content of adhesives, and the fiberglass mesh has poor alkali resistance. Only a few years ago, the outer surface of the protective surface is cracked, and maintenance is required.

2. Thermal bridge of steel mesh frame cement sandwich panel insulation wall

Steel mesh frame cement sandwich panel insulation wall In addition to the thermal bridge of the above-mentioned EPS board thin plastering wall, there are 200 Φ2 steel wire penetration insulation layers per square meter to increase heat transfer, and the connection with the base wall Increased heat transfer, the thermal conductivity of the EPS board after correction should be greater than 0.08 w/mk, which is 60% more heat transfer than the EPS board thin plastering wall, and the adverse effects of the wetness of the insulation layer in long-term use are not counted. The thickness of the insulation layer will increase much more than the thickness of the thin plaster insulation wall.

3, sandwich thermal insulation wall thermal bridge At present, a large number of sandwich insulation walls are used in Heilongjiang Province, and even high-rise buildings are also widely used. The sandwich insulation wall has a concrete bridge with a concrete picking plate along the circumference of the building, and the outer wall is compared to a cotton coat. Each layer of the sandwich insulation wall has a non-insulated belt - a concrete picking plate. There is also a heat bridge around the hole, and the inner and outer leaf masonry pulls the steel bridge. Figure 3 shows the heat loss route (shown in the curve) of the sandwich thermal insulation wall of the pick-up plate at the thermal bridge of the pick-up plate at the heat bridge of the pick-up plate. However, even if the outer end of the hot plate of the picking plate is pasted with the heat insulating strip as shown in Fig. 3, the extension of the heat bridge is small, and the improvement of the heat preservation is hardly effective. According to the “Design Standard for Energy Efficiency of Residential Buildings in Heilongjiang Province”, the linear heat transfer coefficient of the cantilever plate with a thickness of 120mm and no insulation is assumed. The thickness of the picking plate is 80mm, and the linear heat transfer coefficient of the thermal bridge of the picking plate is about 0.43w/mk. . The influence of the thermal bridge on the average heat transfer coefficient of the 2.8m high-rise building is analyzed. According to the window-wall ratio of 0.3, the thickness of the EPS board on the balcony board is 100mm, and the thermal insulation of the sandwich heat-insulating wall increases the average heat transfer of the wall. The coefficient is about 0.15~0.2w/m ² .k, plus the thermal bridge around the hole (according to the unsafe calculation, still estimated by the linear heat transfer coefficient of the thermal bridge of the thin plastering hole), the total heat transfer coefficient of the wall is increased. About 0.25~0.3w/m ² .k ! According to the “Design Standard for Energy Efficiency of Residential Buildings in Heilongjiang Province”, the average heat transfer coefficient limit of the wall in the severe cold (B) zone specified in the energy-saving design judgment table for residential buildings can be obtained. The main wall sandwich insulation should be about the heat transfer coefficient, see Appendix 2.

Schedule 2 Severe cold (B) residential building considering the influence of linear heat transfer coefficient, the heat transfer coefficient of the main wall of the sandwich thermal insulation and the required thickness of the insulation layer

Note: 1. The data in Schedule 1 includes the influence of the thermal bridge of the thermal insulation balcony panel, the thermal bridge of the portal, and the thermal bridge of the cantilever beam on the average heat transfer coefficient of the wall.

2. The average heat transfer coefficient limit ratio of the wall in severe cold (A) area is also reduced by 0.05w/m ² , which is more difficult to achieve. However, the thermal bridge of the sandwich insulation wall should be much larger than the thermal bridge of the EPS board thin plastering insulation wall. The heat transfer coefficient of the main wall of the attached table 2 should not be satisfied, and then consider the core. It is also meaningless to increase the value of the thermal bridge at the entrance of the thermal insulation wall. In the "Code for Design of Masonry Structures" GB50003, the thickness of the sandwich insulation intermediate insulation layer should not exceed 100mm, so it is impossible to meet the requirements of Schedule 2.

There are other problems with the sandwich insulation wall: The gap between the installed EPS board and the surrounding masonry, concrete picking board and EPS board is very large, which is difficult to control during construction, which increases the convection of the air inside and outside the EPS board. Heat transfer; The exterior decoration of the sandwich insulation wall is usually a facing brick. During the heating period, the indoor water vapor is blocked from being emitted to the outside. The insulation layer in the severe cold area contains a large amount of moisture, which is far beyond the specified EPS plate. 15% of the regulations, insulation The effect is reduced, as well as the increased heat transfer of the pull bars, which are not included in the above analysis. How many of the large number of sandwich insulation buildings that have been built can meet the 50% energy saving standard? It is even less able to meet the 65% energy saving standard in severe cold regions.

It should also be pointed out that the tensile reinforced paint anti-corrosive paint between the inner and outer leaf masonry has a limited durability, and the tensile reinforcement between the inner and outer wall walls is corroded after about 20 years in a humid environment. The outer leaf masonry is in danger of collapsing and hurting people!

Some countries in the world, such as Russia, use a three-layer wall with a double-layer insulation layer. The extension of the thermal bridge can reduce the thermal bridge, but the influence of the thermal bridge is still large, and its structure is not suitable for high-rise buildings. Body and base cost, greatly reducing the use of area.

4, insulation block wall

The thermal insulation block wall is close to the thermal bridge of the splicing plate and the hole and the thermal bridge of the sandwich thermal insulation wall, but the following problems still exist: 1 The insulation layer is divided into broken insulation blocks by sand, slag, ceramsite, cement, etc. Wall, from the purpose of the transmission of heat insulation capacity, its structure is unreasonable, how thick is the insulation block wall of the main wall part of the severe cold area to meet the requirements of the average heat transfer coefficient of the wall in Schedule 2? If the insulation effect of EPS board and XPS board is compared with down or cotton, then some materials with higher thermal conductivity can be compared to old cotton or catkins. The insulation block can be compared to the slag, sand and cement in down or cotton. Wall or material. 2 Some structural diagrams focus on the data of the thermal insulation block wall. Does it consider the influence of unfavorable factors during construction, and the effect of moisture on the insulation and energy saving effect of the insulation layer in long-term use?

5, internal insulation wall

The inner thermal insulation wall has a thermal bridge along the perimeter of the building. The thickness of the slab must be greater than the thickness of the slab. There is also an indoor partition wall thermal bridge. The thickness of the indoor partition wall masonry in the multi-storey building is 0.37m, 0.24m, and the thickness of the high-rise building. A concrete wall of about 0.2~0.3m, a large number of non-insulated indoor partition walls of the inner thermal insulation wall - just like the cloth between the front and the back of the cotton cloth is connected, but no cotton near the joint becomes a thermal bridge. The thermal insulation of the inner insulation wall is far more than the thermal insulation of the sandwich insulation wall! The inner insulation wall has a strip of cotton that does not have cotton. Of course, the insulation is not good. Even the developed technology in Japan uses internal insulation to spray polyurethane insulation on the indoor wall. In China's "Civil Building Energy Efficiency Design Standards" JGJ26-95 Appendix C points out: Under internal insulation conditions, concrete beams, columns and other surrounding thermal bridges increase the average heat transfer coefficient of the wall by 51~59%. Unfortunately, a large number of insulated buildings have been built in North China.

6, curtain wall decorative wall

The large number of steel profiles used in curtain wall decoration buildings are dense, with a spacing of about 0.8~1.2m. The heat transfer capacity of steel is too large, and its thermal conductivity is 33 times that of concrete. How can it meet the requirements of building energy conservation?

7, prefabricated insulation wall panel wall.

The prefabricated thermal insulation wall panel wall is used for the frame structure infill wall, and the price is high. In addition, prefabricated insulation wall panels have the following problems:

1) Prefabricated wallboards have many joint thermal bridges. The joint thermal bridge has a great influence on the average heat transfer coefficient of the wall. Some projects use prefabricated light steel skeleton insulation wall panels, and the joints are cracked and cold-sealed after installation. Dew, make the indoor floor tilt up and become Quality problems that cannot be solved by general maintenance (if completely solved unless there is another layer of insulation on the outer wall).

2) The connection between the prefabricated wall panel and the frame beam and column is mostly an external installation welded by anchor bolt or pre-embedded steel plate, the force is not clear, and the stress is concentrated.

3), anchor bolts are divided into metal anchor bolts and plastic anchor bolts, and their durability is questionable.

Through the insulation layer, steel without alkaline environmental protection is easily corroded, especially in the wet state. The metal anchors should preferably be of a higher grade stainless steel, followed by hot-dip galvanized or chrome-plated steel, but a considerable number of engineering anchors are ordinary steel. The plastics currently known to have higher strength are polypropylene and nylon, but these two plastics are not resistant to aging. The durability of polypropylene is 10 to 30 years, and it is difficult to judge its durability. Plastics are suitable for use as parts that are easy to replace and should not be buried in the wall as the main force member.

To compare the thermal insulation of wall insulation, internal insulation and thermal insulation blocks with more thermal bridges: The insulation layer in these building exterior walls is used as warm cotton for exterior wall cotton, but there is a lot of concrete between cotton. , mortar, and even steel, etc., how can it be insulated?

The inventor of the present patent application has filed the patent number 200410002698.7, and the invention patent name is "the earthquake-resistant thermal insulation composite wall with the support and the outer layer of the reinforced concrete", and the patent number 200610153289.6, and the patent name of the invention is "supported bundled composite" Two patents for "insulation walls", these two patents also have a hot bridge at the hole. In order to ensure the thickness of the protective layer of the hole, the thickness of the plaster layer of the hole needs to be 30mm. The linear heat transfer coefficient of the thermal bridge through the cement mortar layer of the hole is about 0.2w/mk. Even if the insulation is decorated with the decorative line, the length of the thermal bridge is extended to 200mm, linear. The heat transfer coefficient is also about O.lw/mk, which is unfavorable for energy-saving insulation and increases the cost. Due to the large number of door and window openings, the hot bridge of the plastering layer has a great influence on the building energy saving.

Thermal bridges have increased the difficulty of architect design calculations, and because of the high heat transfer capacity of these thermal bridges, the thermal design engineers have to deal with such things as sandwich insulation walls, thermal insulation blocks, etc. Estimated heat consumption of the wall, how can the expected building energy saving goal be achieved? The Institute of Chinese Academy of Building Sciences 2003-2005 heating season continuous testing of some energy-efficient buildings in Beijing found that the measured results of buildings built according to the energy-saving 50% standard reached 37% energy saving, and buildings with energy saving of 30% actually saved only 7%! Some regions have implemented the 65% energy saving standard. Due to the imperfect wall technology, it is expected that the national energy saving target will not be met on average.

The above illustrates the problems existing in the current energy-saving wall technology. The problems existing in the energy-saving wall technology have a great impact on energy conservation and emission reduction, the construction of a low-carbon society, and the sustainable development of society, and the sequelae are serious.

The calculation of heat loss, especially the heat loss of various heat bridges, is a very complicated problem. Because of our understanding of the thermal bridge and the understanding of the performance of some building materials, we have paid tuition for the detour. In the case of various wall technologies with various problems, investors and designers have also fallen into a helplessness when choosing energy-saving walls.

In order to effectively reduce the heat bridge of the hole, improve the energy saving level of the wall, facilitate the construction, reduce the cost, and make up for the deficiencies of the aforementioned patents, the supported external wall thermal insulation composite wall of the present invention solves this problem.

Second, analyze the reasons for the problems existing in the current wall insulation technology, and propose ways to solve the problem:

Reason for the problem: The thin plastering insulation wall is only connected by bonding the insulation layer to the wall, and the polymer insulation layer The outer side is made of 3~4mm cement polymer mortar with glass fiber mesh as the protective layer. The natural fire is not good, the outer surface is unsafe, and the durability is not good. The method of sandwich insulation, thermal insulation block and internal thermal insulation wall installation of thermal insulation material is too primitive, too simple, and there are many natural thermal bridges. There are also thermal insulation materials such as steel mesh benzene plates with high thermal conductivity and poor thermal insulation.

There are two reasons why the problem of energy-saving walls has not been solved for a long time: First, no reliable structural measures are taken to ensure the safety of the outer protective layer and minimize the thermal bridge; the second is that the ordinary cement mortar is not solved. The reliable bonding of the ash and the polymer insulation layer, so as to avoid the problem of the quality of the plaster layer cracking; the third is that the heat bridge problem of the hole has not been effectively solved, including the two patents mentioned above. Solve the problem of hot bridge at the hole, and the structure of the hole is troublesome.

Summary of the invention

It is an object of the present invention to provide a supported exterior wall exterior insulation composite wall construction.

The purpose of the invention is as follows: 1. The heat bridge is greatly reduced. On the basis of the invention of the present invention, the heat bridge of the hole is eliminated or greatly reduced, and the heat transfer coefficient of the main wall and the average heat transfer coefficient of the wall are reduced. The difference between the two, to provide a reliable energy-saving insulation wall structure, on the basis of minimizing the thermal bridge, but also to ensure the safety of the outer protective layer; Third, to provide a convenient construction of the composite wall Body structure; Fourth, a composite wall structure with a concrete-supported cantilever beam provided with a curtain wall decoration with a large decorative exterior.

The first supported external wall external thermal insulation composite wall of the present invention is: the present invention comprises a base wall, a concrete cantilever beam support member, an insulation layer, a mesh tensile material, a vertical reinforcement, a protective layer, a door and a window, and The main structure of the building is a concrete wall, a load-bearing masonry wall, a non-load-bearing lightweight masonry infill wall or a steel-wood or bamboo-wood wall; the insulation layer is a molecular insulation material or a mineral wool felt or a plant straw board or a paper honeycomb board or a thermal insulation mortar or a foamed concrete; the mesh tensile material is an alkali resistant mesh cloth or a metal mesh or a bamboo mesh; the protective layer is cement mortar or fine stone concrete, or modified Cement mortar or fine stone concrete, or thermal insulation mortar; the main structure of the building is a concrete member or a steel member, and the main structure of the building comprises a beam, a plate, a column, a wall, a foundation; an inner end of the concrete cantilever beam support member and the main body of the building The structure is fixedly connected or fixed in the base wall of the load-bearing masonry; the insulation layer is fixed on the outer side of the base wall and the main structure of the building; the vertical reinforcement is welded and fixed on the concrete cantilever beam On the pre-buried steel plate of the outer end of the bearing, there are vertical reinforcing bars on the side of the door and window; the outer or inner side of the vertical reinforcing bar has a mesh tensile material, and the mesh tensile material is fixedly connected with the vertical reinforcing bar; The mesh tensile material is buried in the protective layer, or the alkali-resistant mesh cloth is adhered to the surface of the protective layer; the door and window of the invention is installed on the insulating layer of the opening, and is provided on the outer side of the thermal insulation layer and on the indoor and outdoor sides of the door and window. Protective layer, a supported external wall external thermal insulation composite wall forming a hole insulation bridge.

The invention can reduce the effect of the hot bridge of the prosthetic plate and the thermal bridge of the indoor partition wall. The outer wall of the heating area is like a cotton coat. The supported external wall thermal insulation composite wall of the invention has no sandwich thermal insulation wall, An uninsulated belt left on each layer of the insulation block wall—concrete prosthetic plate; there is no indoor insulation wall with a large amount of insulation inside the wall. It is like the cloth between the front and the back of the cotton cloth. But there is no cotton near the seam Flowers; There is also no insulation layer for the insulation of the block wall with a large amount of insulation materials such as mortar and slag. The invention can reduce the effect of the heat bridge of the door and window opening. The outer wall of the heating area is like a cotton coat. When we feel that the neck is cold, it is necessary to surround the woolen scarf to feel warm, if only by increasing the thickness of the cotton coat to solve the cold neck. The problem, the effect is not obvious. Through the reasonable door and window opening structure, the heat transfer heat loss around the door and window openings can be reduced, which is like a scarf on the neck. However, there is only one person's neck, and the number of doors and windows in the building is very large. Therefore, there is a lot of heat lost in the heat bridge at the entrance, which has a great impact on building energy conservation. In particular, the lower the heat transfer coefficient of the wall, the greater the significance of the heat insulation of the hole. This is like the weather is particularly cold, the neck must be surrounded by a woolen scarf. It can be seen from the following Table 4 that the supported external wall external thermal insulation composite wall of the present invention is close to the thermal insulation effect of the EPS board thin plastering insulation wall of 250 mm when the thickness of the insulation layer EPS board is 150 mm! This is because the insulation layer around the hole of the thin plaster insulation wall is too thin.

The supported external wall external thermal insulation composite wall of the invention only has about 10% of the concrete cantilever beam support member of the prosthetic plate thermal bridge is a thermal bridge, which is like a cotton button, which is to ensure the safety of the wall insulation system. Indispensable, in addition to the button - concrete cantilever beam support, the formation of the insulation layer through, like skin, down jacket, cotton jacket in insulation, so insulation. If the heat transfer of the concrete cantilever beam support is further reduced, lightweight aggregate concrete is required, but as long as the indoor condensation does not occur, the lightweight aggregate concrete is generally not required because the concrete cantilever beam support is small in area.

The second supported external wall external thermal insulation composite wall of the present invention comprises: a base wall, an insulation layer, a steel strip or a section steel, an outer decorative large board protection layer and a building main structure; the invention also includes a concrete suspension The beam support member; the base wall is a concrete wall, a load-bearing masonry wall, a non-load-bearing lightweight masonry infill wall; the insulation layer is a polymer insulation material or a mineral cotton or plant straw board or a paper honeycomb board or insulation Mortar or foamed concrete; the main structure of the building is a concrete member or a steel member, the main structure of the building comprises a beam, a plate, a column, a wall, a foundation; the inner end of the support member of the concrete cantilever beam is fixedly connected with the main structure of the building, or concrete The inner end of the cantilever beam support member is fixed in the base wall; the steel strip or steel is vertically welded or horizontally welded to the embedded steel plate at the outer end of the concrete cantilever beam support; the outer decorative large plate protective layer and Steel plate strip or section steel fixing; between the outer decorative large-layer protective layer and the base wall, and between the outer decorative large-plate protective layer and the main structure of the building Exterior insulation wall is formed with a support wall is provided with a decorative concrete cantilever beam support member of.

The technical effect of the invention is that: when the supported external wall external thermal insulation composite wall body is insulated and broken at the door and window opening, the heat bridge of the door and window opening can be "0"! The thermal insulation effect of the wall external thermal insulation composite wall is better than the current thermal insulation effect. Far more than other various insulation walls. The supported external wall external thermal insulation composite wall of the heat insulation broken bridge of the invention has the best heat preservation, good durability, good fireproofing, meets any decoration, has good safety of outer protective layer and outer facing layer, and is convenient in design and construction. Convenient and comprehensive superiority; a supported external wall external thermal insulation composite wall with a curtain wall decoration with concrete truss girder support is better than the steel reinforced curtain wall and has good durability. The invention is of great significance for building a low-carbon society for social energy conservation and emission reduction, and for coping with global climate change.

China and many countries in the world have no conditions to construct Nordic wood structures, but the outer walls of concrete walls or various masonry walls with insulated walls can be used to support the Nordic wood composite wall. Wall Body height insulation and energy saving level. The invention can be widely applied to wall insulation and energy-saving projects with concrete walls and masonry walls as the base wall.

The supported outer wall outer thermal insulation composite wall protective layer of the invention is reliably connected with the main structure of the building through the cantilever beam support member and the welded steel bar welded thereon, and the outer protective layer plastering and the decorative layer form a suspended curtain wall, the structure Good safety, good fire safety; bonding between layers of composite wall to prevent cracking caused by empty drum; prevent the weathering and frost heaving caused by the strength of the watering protective plaster layer Exfoliation, cracking, and durability of the composite wall plastering layer can be as durable as the plastering layer on the brick wall. When installing windows and doors, it can be connected with the indoor base wall by connecting steel sheets, and it can be connected with the outer protective layer (some connecting steel sheets are connected with the indoor base wall, and some connecting steel sheets can be connected with the outdoor plastering layer). When the window is a plastic profile, the heat transfer is blocked by the plastic profile, no heat bridge between the two inner and outer steel plates is generated, and the door and window and the heat insulation layer are sealed with polyurethane foam to strengthen the connection, so the door and window are installed in the insulation layer. Security is guaranteed.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS First, referring to FIG. 1 to FIG. 6, a supported external wall external thermal insulation composite wall body comprises a base wall body 1, a concrete cantilever beam support member 10-5, an insulation layer 3, and a mesh shape. The tensile material 5, the vertical steel bar 4, the protective layer 8, the door and window 20 and the building main structure 10 are composed; the base wall 1 is a concrete wall, a load-bearing masonry wall, a non-load-bearing lightweight masonry infill wall or steel wood, a wall of bamboo wood; the insulating layer 3 is a polymer insulation material or a mineral wool felt or a plant straw board or a paper honeycomb board or a thermal insulation mortar or a foamed concrete; the mesh tensile material 5 is an alkali resistant mesh cloth 5 -1 or metal mesh 5-2 or bamboo mesh 5-3; the protective layer 8 is cement mortar or fine stone concrete, or modified cement mortar or fine stone concrete, or thermal insulation mortar or EPS board thin plaster insulation The building main structure 10 is a concrete member or a steel member, and the building main structure 10 includes a beam, a plate, a column, a wall, a foundation; and an inner end of the concrete cantilever beam supporting member 10-5 is fixedly connected with the building main structure 10. , or fixed to the base of the load-bearing masonry The wall 1 is fixed on the outer side of the base wall 1 and the main structure 10 of the building; the vertical reinforcement 4 is welded and fixed on the embedded steel plate at the outer end of the concrete cantilever beam support member 10-5, the door and window opening The side is provided with a vertical reinforcing bar 4; the outer side or the inner side of the vertical reinforcing bar 4 has a mesh tensile material 5, and the mesh tensile material 5 is fixedly connected with the vertical reinforcing bar 4 (bundling or by bonding with a plaster protective layer) The vertical reinforcing bar 4 and the mesh tensile material 5 are buried in the protective layer 8, or the alkali-resistant mesh cloth 5-1 is adhered to the surface of the protective layer 8; the door and window 20 is installed on the insulating layer 3 of the opening, in the thermal insulating layer 3 The outer side and the inner and outer sides of the door and window 20 are provided with a protective layer 8 to form a supported outer wall outer thermal insulation composite wall of the hole heat insulating bridge.

' Modified cement mortar or fine stone concrete is cement mortar or fine stone concrete with additives such as admixture, fly ash, etc. It also includes cement polymer mortar or polymer concrete formed by adding adhesive, and protective layer in the position of reinforcing steel. The use of polymer mortar or polymer concrete is beneficial to prevent corrosion of the protective steel bars, and the thickness of the plaster protective layer can be reduced. The protective layer plastering is resistant to cracking by polymer mortar or polymer concrete, which is most beneficial for increasing the durability.

When the heat insulating layer of the present embodiment is a polymer material, for example, an EPS board for an insulating layer should be made of a heat insulating material having good fireproof properties at the door and window opening, so that the insulating layer of the composite wall is two materials, and the mineral wool or the insulating material can be insulated. The mortar acts as an insulation layer around the hole. The thermal insulation mortar has vitrified micro-bead insulation mortar, which has the advantages of good fireproof performance and wide material. The thermal conductivity of the thermal insulation sand can reach 0.07 w/mk, and the thermal insulation effect of mineral wool is higher than that of thermal insulation mortar. In the warm area, the inner and outer sides of the door and window profiles of the entrance should also be insulated with mortar or adhered to the outer side of the EPS board as a protective layer 8, that is, as shown in Figure 1, the insulating mortar or EPS board serves as the insulation layer. The thermal insulation mortar or the thin plaster insulation strip glued on the outside of the hole can be used as the protective layer on both sides of the door and window profile. The thermal insulation mortar or the thin plaster insulation strip can be used as the protective layer on both sides of the portal door and window profile. : 1. Further extend the distance between the indoor base wall and the outdoor, and reduce the heat bridge at the hole; 2. Prevent condensation in the door and window profiles. The rubber powder polystyrene granule insulation slurry shrinks in the fire benzene plate particles, forming a cavity, and can also block the fire spread, so it can be used as a hole insulation layer, and can also be used as a protective layer on both sides of the door and window. In non-heating areas or non-cold areas, the heat transfer coefficient of the wall is not very strict. The cement mortar is used as the protective layer 8 on both the inner and outer sides of the door and window profiles, but the inside of the doors and windows in winter should not be dew condensation. The thermal conductivity of foamed concrete is 0.1~0.25w/mk, which can also be used on the insulation layer around the door and window opening, that is, the insulation layer can be different materials at different positions, in order to increase the waterproof performance, foaming An elastic polymer adhesive should be added to the concrete to prevent cracking and waterproofing of the hole.

In the embodiment, the door and window are installed on the insulation layer of the hole, and the plaster is protected on both sides of the door and window, that is, there is no cement mortar plastering layer thermal bridge between the door and window frame and the heat insulation layer, and the cement mortar plastering layer thermal bridge is The door and window are partitioned, which extends the distance between the outer corner of the indoor base wall and the outside. As shown in Figure 1, the interior side plaster layer of the base wall cavity is also plastered with thermal insulation mortar (or rubber powder polystyrene ash plaster insulation, or rock wool board plaster insulation), and further extended the base layer. The distance between the outer corner of the wall and the outdoor, that is, the insulating sand paddle or other insulation material used as the indoor hole plastering leveling layer is more advantageous for the wall insulation. The thickness of the insulation layer of the hole insulation bridge structure should be greater than the thickness of the door and window profile. Otherwise, although the heat bridge of the hole is also reduced, the effect of the heat insulation bridge will be reduced. When the indoor and outdoor plastering of the door and window profiles is made of thermal insulation material, the distance between the outer corner of the indoor base wall and the outdoor is increased, and the heat preservation of the door and window frame is beneficial. The heat dissipation effect of the building and the window can be further increased, and the door and window can be further increased. The linear heat transfer coefficient of the hole can even be negative! It is of great significance to reduce the heat transfer coefficient of the wall and improve the energy saving effect of the wall insulation.

When the building has externally suspended concrete members, such as balcony panels and inclined roof panels, the externally suspended concrete members can be used as the fixed ends of the vertical reinforcements of the composite wall, so that no additional cantilever beam supports are required. 10-5, that is, the outer overhanging concrete member replaces the concrete cantilever beam support member 10-5. The vertical reinforcing bar of the composite wall located under the window sill, or the insulated balcony slab or the insulated parapet wall is only fixed at one end to the steel plate of the concrete cantilever beam support, as shown in Fig. 3 and Fig. 4.

The template of the concrete cantilever beam support member 10-5 can be made of iron sheet, the four corners of the template can be cut and fixed on the template of the main structure, and the iron sheet can be wrapped and wrapped with the tape paper, and the tape paper can be disassembled when the mold is removed, and the construction is simple. , see Figure 5. The concrete cantilever beam support member 10-5 protrudes about 10mra outside the insulation layer 3, and the welding vertical reinforcement is convenient to construct. When the steel structure is connected, the embedded steel plate at the rear end of the precast concrete cantilever beam support is welded to the steel structure.

When the thermal insulation layer is a polymer thermal insulation material, the thermal insulation layer is adhered and fixed to the base wall by cement polymer mortar. The interface layer is applied to the polymer insulation layer to bond the plaster protection layer 8 to the insulation layer 3. The interface agent shall be constructed according to the invention name as "the interface agent is used for plastering cracking, adding plastering and veneer bonding strength", and the patent application number is 200810063815.9, and the invention number is CN101215857A.

The alkali-resistant mesh cloth is a simple name for the alkali-resistant glass fiber mesh in the JCT-841-2007 standard. The alkali-resistant mesh cloth has a strength retention rate of not less than 80% in the ordinary Portland cement of the strong alkali, and the alkali-resistant mesh cloth has a considerable tensile strength. The GRC wallboard that has been added to the alkali-resistant chopped glass fiber from the 1970s abroad has been used for nearly 30 years. Especially the alkali-resistant mesh is used for indoor indoor use. . By multiplying the alkali-resistant strength retention value of the alkali-resistant mesh cloth by a certain safety reserve coefficient as the design value of the alkali-resistant mesh tensile strength, the design calculation can be carried out in comparison with the steel bar and the steel wire mesh. Bamboo mesh is suitable for simple low-rise buildings.

Embodiment 19 is another method of installing the curtain wall decoration, and the nineteenth embodiment is more convenient for construction than the thirteenth and fourteenth embodiments. When using 髙 molecular insulation material, pre-composite fireproof panels such as cement fiberboard and calcium silicate board on the outside of the insulation layer are suitable to increase fireproof performance, and fire barriers may also be provided, for example, horizontal steel at a certain height. A cement mortar with a height of 100 to 200 mm is poured into the gap between the insulation layer and the insulation layer. The decorative slab 8-1 on the outside of the curtain wall is usually made of stone, veneer slab or glass, or aluminum gusset plate.

When the insulation layer is thermal insulation mortar or foamed concrete, it can be poured on the site between the outer protective layer and the base wall. The opening can be constructed by using an insulated bridge according to the first embodiment.
