Problems solved by technology

This type of brick-concrete block mostly adopts lightweight brick and aerated concrete block structure, and its biggest defect is that it cannot meet the thermal insulation and energy-saving requirements of the external wall (it must be treated as an external thermal insulation structure); at the same time, this type of brick The construction of wall blocks is difficult and inefficient, its structural stability and seismic performance are poor, and the overall cost is high

Embodiment Construction

[0021] Such as Figure 1-2 As shown, the sandwich composite exterior wall panel is composed of two side panels 10, 20 and core material layers 30, 31, 32, 33, the sandwich composite exterior wall panel is a cuboid wall panel structure, the side of the exterior wall panel The end faces are provided with interfitting mortise joints, and the tenon joints are respectively located on the long side end faces of the wall panels. The tenon joint is a tenon 34 and a tenon groove 35 , the tenon 34 is a protruding edge with a trapezoidal cross section, and the tenon groove 35 is a trapezoidal groove matched therewith. The specifications and models of the exterior wall panels are: length × width × thickness (1000-3000mm) × (600-610mm) × (150-200mm). A core material layer is filled in the middle of the light aggregate concrete, and the core material layer is a building light aggregate concrete filling structure in which a reinforced mesh 32 is embedded with a polystyrene foam board 33 and ...

Abstract

The invention relates to a sandwich composite external wallboard, which is characterized in that the external wallboard comprises panels on two end faces; a lightweight aggregate concrete sandwich layer is filled between the panels; the middle of the sandwich layer is that a reinforcing mesh is embedded in a polystyrene foam board; and building lightweight aggregate concrete filled structures of ceramic particle, ceramic sand and pearlite are distributed on other parts of the sandwich layer. The novel composite external wallboard is rational in structural design and firm to install and fix. Besides the advantages of the current external wall body, the external wallboard has the advantages of good heat insulation coefficient, good wind resistant capacity, convenience and quickness for construction and installation, good joint integral firmness and stability and high integral intensity. The earthquake resisting capacity and the safety performance of buildings can be greatly increased.

Description

technical field [0001] The invention belongs to non-load-bearing external partition walls for buildings, and in particular relates to a novel composite external wall panel with thermal insulation in the external wall body, convenient and fast construction and installation, and low overall cost and manufacturing cost. Background technique [0002] Most of the non-load-bearing external walls of existing buildings are constructed in the way of plastering cement and gypsum layers behind the brick wall blocks. The construction period is long, the thermal insulation performance is poor, and the moisture-proof and waterproof effects are not good. Especially when external wall insulation is required, the construction is difficult and the construction cost is high. [0003] With the continuous innovation of building materials, a variety of lightweight bricks and concrete block exterior walls have been developed, which can be produced in a factory and installed on site. This type of ...
