External insulating layer of external wall of ultra high-rise building and its making method

Abstract

A thermally insulating layer for the external surface of ultra-high building is composed of steel bars planted in said external surface, insualting boards, steel bar net, meshes steel sheet layer, concrete layer and decorative surface layer. Its technology includes such steps as planting steel bars in external surface, installing insulating boards, binding steel bar net and then meshed steel sheet layer, casting concrete, and applying decorative surface. Its advantages are high strength, not cracking and low cost.

Description

Technical field [0001] The present invention belongs to general building structure; wall; roof; ceiling; insulation or other protection technical fields of buildings, and specifically relates to insulation or other protection specially used for heat preservation. Background technique [0002] An important aspect of building energy saving is to transform the traditional building envelope structure and improve its thermal insulation performance, which is one of the main measures to reduce heating energy consumption in residential buildings. In order to greatly improve the thermal insulation performance of building exterior walls, composite exterior walls composed of structural materials and high-efficiency thermal insulation materials are usually used. There are three structural forms of the composite exterior wall, namely the inner insulation layer, the middle sandwich insulation layer and the outer insulation layer structure. At present, the commonly used building insulation stru...

Problems solved by technology

In theory, it can withstand vertical and horizontal shear stress. In fact, because the problem of layered unloading has not been solved, its height cannot be developed to a high level. Any steel material has stress deformation restrictions and deflection, which is the same as the self-weight of the insulation layer. When the vertical load exceeds the stress and deformation limit of the material, stress and deformation will occur, which will loosen the insulation layer and even cause danger.

Galvanized wire mesh and galvanized iron wire connected to the wall have poor pull-out resistance and are expensive. Galvanized steel wire mesh and obliquely inserted steel wire mesh have high cost and poor pull-out resistance. Polymer mortar is used for the first layer, the thickness is relatively thin, the fire performance is poor, and the finish can only be painted

There is also a cast-in-place integrated type, that is, the external insulation and the structural wall are poured together, so that the lateral pressure and dynamic pressure caused by the vibrating concrete are easy to damage the insulation board and affect the effect.
