Precast concrete exterior wall cladding

Abstract

The invention discloses a prefabricated concrete exterior wall hanging plate which comprises an upper plate body, a middle plate body and a lower plate body, first gaps are formed among the upper plate body, the middle plate body and the lower plate body, and second gaps corresponding to the first gaps are formed in an upper horizontal support, a lower horizontal support and a vertical support. The embedded bolt is fixed on a first embedded plate embedded in a floor beam of a main body structure through a connecting plate, the embedded angle steel is connected with a supporting bolt, and the supporting bolt is arranged on a second embedded plate embedded in the floor beam of the main body structure. According to the external wall scraper, the error allowable range is effectively enlarged, the installation error is small, the waterproof performance is more reliable, the appearance of joints is more vertical, the building facade effect can be achieved through combination of external wall scrapers of various specifications, and the requirement for normal use or deformation can be met under the load or action combination working conditions such as self weight, wind and shock.

Description

technical field [0001] The invention relates to the technical field of construction, in particular to a prefabricated concrete external wall hanging board. Background technique [0002] Exterior wall cladding is a kind of building material, which is a building board used for exterior walls. External wall hanging panels must have basic properties such as corrosion resistance, high temperature resistance, aging resistance, no radiation, fire prevention, insect resistance, and no deformation. At the same time, they must also have beautiful appearance, simple construction, environmental protection and energy saving. Common exterior wall hanging boards include fiber cement boards, aluminum-plastic boards, PVC boards, and stone materials. [0003] During the construction of the existing external wall hanging boards, when the boards are connected, the hooking of two adjacent boards needs to make the width of the hooking hooks suitable for the thickness of the bending part of the t...

AI Technical Summary

Problems solved by technology

[0003] During the construction of the existing external wall hanging boards, when the boards are connected, the hooking of two adjacent boards needs to make the width of the hooking hooks suitable for the thickness of the bending part of the transition board forming the hooking groove. Only at this time can the hooking be relatively stable, the allowable installation error range is small, and there will be no gaps that can be shaken, so that the exterior wall laid with this type of exterior wall siding will form uneven conditions, and the joints will be uneven. Poor look and feel, inconvenient to combine to create a building facade effect
