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

Abstract

An external thermal insulation layer of an outer wall of a super high-rise building. Planting steel bars are arranged on the concrete external wall. The distance between a planting steel bar and an adjacent planting steel bar is 350 mm to 450 mm, and the distance between them is evenly distributed. The steel bar is 60mm away from the edge, and the planted steel bars on the four sides of the window opening on the concrete exterior wall are 60mm away from the four sides of the window opening. On the surface of the concrete exterior wall and on the planted steel bars, there are insulation boards, and on the externally planted steel bars on the insulation board, there are external wall The gravity of the external insulation layer is transmitted to the steel mesh between the planted steel bars, and the steel mesh is installed on the steel mesh to resist crack deformation and stress deformation, and a concrete layer is arranged inside the steel mesh and steel mesh and outside the steel mesh , a finish layer is provided outside the concrete layer. The production method is as follows: drawing hole lines for inserting steel bars on the concrete outer wall, inserting planting steel bars, installing insulation boards, binding steel meshes, binding steel plate nets, making concrete layers, exterior decorative surface layers, and inspecting.

Description

technical field [0001] The invention belongs to the technical field of general building structure: wall; roof; ceiling; building insulation or other protection, and specifically relates to insulation or other protection specially used for heat preservation. Background technique [0002] An important aspect of building energy conservation is to transform traditional building envelopes and improve their 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 building insulation structure commonly used...

AI Technical Summary

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.
