Heat preservation plate with reinforcing bars and heat preservation structure construction method of heat preservation plate with reinforcing bars on outer wall concrete part

Abstract

The invention discloses a heat preservation plate with reinforcing bars and a heat preservation structure construction method of the heat preservation plate with the reinforcing bars on the outer wall concrete part. The heat preservation plate with the reinforcing bars comprises a heat preservation plate body and reinforcement bar net pieces laid in the heat preservation plate; wherein nodes of the multiple reinforcement bar net pieces extend out of connection reinforcing bars. According to the heat preservation structure construction method of the heat preservation plate with the reinforcing bars on the outer wall concrete part, the outer wall concrete part comprises a concrete beam, a concrete shear wall, a construction outer wall balcony, the position of an outdoor air conditioner partition, the position of a bay window and the position of a parapet. During the construction process, the heat preservation plates with the reinforcing bars are connected in a groove and tongue mode, construction sealants are provided for assisting, and it is ensured that no water or slurry leaks in connection positions. According to the heat preservation plate with the reinforcing bars, self-strength, crack resistance and impact ductility of the heat preservation plate can be remarkably improved, and the heat preservation plate can bear certain vertical loads and horizontal loads besides bearing self gravity loads.

Description

technical field [0001] The invention belongs to the field of building wall materials and construction methods of exterior walls, and in particular relates to a thermal insulation board with reinforcement and a construction method of thermal insulation structure at the concrete part of the exterior wall. Background technique [0002] In a building, the energy loss of the outer envelope structure is the largest, and the thermal insulation performance of the envelope structure is the main factor affecting the energy consumption of the building. The weakest part of the outer envelope structure is the part where the outer envelope is made of concrete. It often becomes the cold and heat bridge part of the wall. Because the thermal conductivity of concrete is very large, the thermal insulation performance of 200mm concrete is not as good as that of 2mm thick extruded board. Therefore, the insulation measures of reinforced concrete parts are the touchstone for testing and maintaining...

AI Technical Summary

Problems solved by technology

This method has a better thermal insulation effect, but there are many construction steps, a large amount of wet work on site, and high requirements for construction technology. Once the bond strength of the cement mortar fails to meet the requirements or hollows appear, the insulation board is easy to fall off, which is for future use. bring security risks

The thermal insulation board itself has low tensile strength, poor crack resistance, and weak impact toughness. It is easy to be damaged and broken during transportation and construction, and the rate of defective products is high. In actual application, it has gone through several cycles of hot summer and severe cold in winter. It is also easy to crack, which leads to water leakage on the outer wall, damage to the outer facade, etc.

[0007] Whether it is an internal thermal insulation system or an external thermal insulation system, the concrete structure needs to be pre-cast and formed. When pouring concrete, building wooden formwork is required. The extensive use of building wooden formwork seriously consumes limited forest resources, which does not meet the "energy saving, reduction The basic national policy of "consumption, emission reduction, and environmental protection" does not meet the requirements of green buildings
