Heat preservation composite wall provided with meshed plaster on two sides

Abstract

The invention provides a heat preservation composite wall provided with meshed plaster on two sides, relates to heat preservation composite walls of buildings, and aims to solve the problem that heat bridges of openings of an energy-saving wall affect the building energy conservation. The heat preservation composite wall comprises a main building structure load-carrying member, short anchoring steel bars, a core layer, a meshed tensile material, outdoor vertical steel bars, indoor vertical steel bars, a supporting cantilever beam piece, outdoor horizontal additional steel bars, indoor horizontal steel bars, doors, windows and protective layers, wherein the short anchoring steel bars and the indoor vertical steel bars are anchored with the main building structure load-carrying member; the outdoor vertical steel bars are fixed with the supporting cantilever beam piece; the outdoor horizontal additional steel bars are fixed with the outdoor vertical steel bars; the outdoor vertical steel bars are fixed with the indoor vertical steel bars; the core layer is fixed between the outside and the inside of a frame; two sides of the core layer are provided with the protective layers; the short anchoring steel bars are overlapped with the meshed tensile material; the doors and the windows are arranged on the core layer; and two sides of the doors and the windows are provided with the protective layers. As the openings of the heat preservation composite wall provided with the meshed plaster on the two sides have a heat insulation broken bridge structure, the energy saving and heat preservation effect of walls is greatly improved.

Description

technical field [0001] The invention relates to a thermal insulation composite wall body of a building, in particular to a thermal insulation composite wall body with mesh plastering on both sides. Background technique [0002] 1. The thermal bridge at the opening of doors and windows is the bottleneck of energy-saving and thermal insulation technology for barrier walls [0003] At present, the best thermal insulation effect in a large number of applications in our country is to paste EPS board thin plaster insulation wall, but the fire prevention is not good, the durability is not good, and the outer surface is not safe. But at present, even if the EPS board with the best thermal insulation is thinly plastered to insulate the wall, since the insulation layer pasted around the opening of the door and window is much thinner than the facade of the wall, more heat will be lost on the side wall of the opening. The "65% Design Standard for Energy Saving of Residential Buildings ...

AI Technical Summary

Problems solved by technology

Even if 20-30mm of insulation strips are pasted on the outside of the hole, the linear heat transfer coefficient ψ value can reach 0.1w / m.k, which is not good for energy saving and heat preservation, and it is difficult to achieve a low heat transfer coefficient

[0011] The thermal bridge at the opening is also a serious problem in the wall energy-saving and heat-preservation technology disclosed by the patent applicant, which affects the energy-saving and heat-preservation effect of the composite wall, especially for the construction of low-energy buildings.

[0012] 2. There is no structure for further strengthening the openings of doors and windows, which makes it inconvenient to install anti-theft fences and heavy decorations at the openings, etc.
