Binding type thermal-insulation composite wall with support

Abstract

The invention relates to a bound thermal-insulation composite wall with supports, which provides an external thermal-insulation composite wall of building, to overcome the defects of present technique. Wherein, the concrete hanging beam support (2), the internal outwards-drawing connector (7), and the inner end of plastic expansion nail (9) are fixed inside the main construct concrete (10) or basic wall (1); the concrete hanging beam support (2) and the outer end of inner outwards-drawing connector (7) are inside the outer protective layer (8) to connect the vertical steel bar (5); the outer side of basic wall (1) has a thermal-insulated layer (3) fixed via plastic expansion nail (9); the outer side of thermal-insulated layer (3) has a vertical steel bar (5); the outer or inner side of vertical steel bar (5) has a metallic network (4) which is connected to the vertical steel bar (5); the outer side of thermal-insulated layer (3) has a outer protective layer (8) made from cement sand pulp or pea stone concrete. The invention has the advantages that safety, long service life, better thermal insulation and flameproof.

Description

technical field [0001] The invention relates to an external thermal insulation composite wall body of a building. Background technique [0002] The world's energy is becoming more and more tense. Building energy conservation is an important issue for the sustainable development of human society. Wall insulation and energy-saving technology is an important part of building energy conservation. The current various wall insulation technologies have the following problems: 1. The contradiction between safety and insulation has not been solved from the perspective of optimization, that is, the wall insulation with good safety is not good; the wall with good insulation is not safe , manifested in unsafe structure or difficult construction quality control, and unsafe fire prevention. The main reason is to solve the connection between the insulation layer and the wall from the material, without relying on structural means or simple structural means. For example, in the heating area...

Problems solved by technology

The current various wall insulation technologies have the following problems: 1. The contradiction between safety and insulation has not been solved from the perspective of optimization, that is, the wall insulation with good safety is not good; the wall with good insulation is not safe , manifested in unsafe structure or difficult construction quality control, and unsafe fire prevention. The main reason is to solve the connection between the insulation layer and the wall from the material, without relying on structural means or simple structural means

Also, because many blocks have their own thermal bridges, these factors have a great impact on building energy saving and high cost, and it is impossible to achieve a low heat transfer coefficient of the wall, especially the lower the heat transfer coefficient of the wall, the greater the impact on the cost and wall thickness

Some use steel anchor bolts to connect with the base wall, but this structural connection is too simple to meet the requirements of large horizontal wind pressure and large horizontal earthquake action on the external wall. When the wall is thickly decorated, the rigidity of steel anchor bolts is too small, it is difficult to meet the safety requirements, and it is even more difficult to anchor reliably with various masonry, such as brick masonry and lightweight filled masonry, and these insulation technologies are used for connecting steel The density of anchor bolts is high, such as the benzene plate of the abdominal wire penetrating steel wire mesh frame, and the steel that penetrates the benzene plate reaches 7.4 / m 2 , increase heat transfer, use non-corrosion or low-corrosion anchor bolts in the insulation layer, which are easy to corrode and affect durability

2. In the heating area with 50% energy saving, when the outer protective layer is decorated with thick cement mortar plaster and block material surface layer, it does not meet the requirements of the "Code for Thermal Engineering Design of Civil Buildings" on the internal condensation and moisture check of the enclosure structure. The moisture content of the layer exceeds the allowable range of the specification, which will affect the durability of the insulation system and affect the insulation effect

I have already proposed a new wall insulation technology solution, which has obtained a patent certificate, the patent number is ZL200410002698.7, the authorized announcement date is January 4, 2006, and the invention name is "supported, with reinforced concrete outer protective layer Anti-seismic thermal insulation composite wall", 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 safety of existing thermal insulation technology bad disadvantage

However, through 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 the following shortcomings: the original patent used the steel support thermal bridge to deal with complicated processing, and the connection between the steel support and the vertical reinforcement Trouble, it is not considered to use the outer end of the plastic expansion nail to fix the insulation board to connect with the metal mesh, so that the distance between the concrete cantilever beam support and the inner and outer pull joints is relatively close, and the installation of the concrete cantilever beam support and the inner and outer The number of tie-ins increases the thermal bridge
