Thermal-insulating binded composite wall with supporter

Abstract

Supported bundling insulated composite wall, relates to outer insulated composite wall for buildings. The purpose of this invention is to solve the problem that existing blocks have their heat bridge, great impact the energy-saving of construction and can not reach the low heat transfer coefficient of the wall. The inner terminal of concrete cantilever strutting piece (2), the level connecting link (7) and plastic bulging nails (9) of the invention are fixed within the concrete structure of the main building (10) or basal wall (1), the outer terminal of concrete cantilever strutting piece (2) and the level connecting link (7) are connecting fixed with vertical steel bars (5) in the outer protective layer, an insulating layer (3) is fixed outer flank of basal wall (1) by plastic bulging nails (9)outer flank of insulating layer (3) is the vertical steel bars (5), out or inside of the bars is set with metal network (4), the outer ends of metal network (4), the vertical bars (5) and the plastic bulging nails (9) are fixed together, the protective layer (8) built by cement mortar or pisolith concrete is found outside the insulation layer (3).the present invention is safe, durable ,with good heat-insulating and fire resisting properties.

Description

technical field [0001] The invention relates to an external thermal insulation composite wall body of a building. Background technique [0002] There are many problems in the current various external wall insulation technologies. In the final analysis, the contradiction between safety and insulation has not been solved, that is, the wall insulation with good safety is not good; the wall with good insulation is not safe, which is manifested in the structure. The main reason why the current wall insulation technology has these shortcomings is that it solves the connection between the insulation layer and the wall from the material, and does not rely on structural means to solve the problem of the connection between the insulation layer and the wall. The connection between the main body of the building and the base wall, so any technology that mixes thermal insulation materials with non-energy-saving materials, there will be thermal bridges in the concrete cornice boards and th...

[0002] There are many problems in the current various external wall insulation technologies. In the final analysis, the contradiction between safety and insulation has not been solved, that is, the wall insulation with good safety is not good; the wall with good insulation is not safe, which is manifested in the structure. The main reason why the current wall insulation technology has these shortcomings is that it solves the connection between the insulation layer and the wall from the material, and does not rely on structural means to solve the problem of the connection between the insulation layer and the wall. The connection between the main body of the building and the base wall, so any technology that mixes thermal insulation materials with non-energy-saving materials, there will be thermal bridges in the concrete cornice boards and thermal bridges around the windows, and many blocks also have their own thermal bridges. It has a great impact on building energy saving, high cost, and it is impossible to achieve the low heat transfer coefficient of the wall

Some have installed insulation materials such as polyurethane on the large decorative panels produced by the factory, and used steel anchors to connect with the base wall, but this connection is too simple to adapt to the large horizontal wind pressure and large Due to the requirements of horizontal earthquake action, when the thicker insulation layer and the outer wall are heavily decorated, it may be difficult to meet the safety requirements because the rigidity of the steel anchor bolt is too small, and it is even more difficult to combine with various masonry, such as brick masonry and lightweight filling masonry. The body is reliably anchored, and the steel anchor bolts have the disadvantages of increasing heat transfer, being easily corroded in the insulation layer and affecting durability

I have proposed a new wall insulation technology scheme, and applied for a patent, the patent application number is 200410002698.7, the publication number is CN1526894A, the publication date is September 8, 2004, and the invention name is "supported, reinforced cement The anti-seismic and thermal insulation composite wall of the outer protective layer", this composite wall still uses traditional thermal insulation materials such as foamed polystyrene board, extruded polystyrene board, polyurethane, mineral wool and other thermal insulation materials, which overcomes the existing thermal insulation Disadvantages of poor technical security

However, during the pilot construction of the 4,674-square-meter elderly dormitory building in Keshan County Social Welfare Institute, Heilongjiang Province in 2005, it was found that there were still some shortcomings: The connection between the support and the vertical reinforcement is troublesome, and the treatment of the thermal bridge is more complicated. The outer end of the plastic expansion nail that fixes the insulation board is not used to connect with the metal mesh, resulting in the gap between the support of the concrete cantilever beam and the horizontal connecting rod. The distance must be relatively short, increasing the workload of installing concrete cantilever beam supports and horizontal connecting rods, and increasing the thermal bridge
