A prefabricated building composite exterior wall panel structure

Abstract

The invention provides an assembled compound exterior wallboard structure of a building. The structure comprises an assembling board A, triangular clamping holes, an assembling board B, triangular clamping blocks, a plastic board and an outer decorative board. An upper clamping structure and a lower clamping structure are separately arranged at the upper and lower ends of the assembling board A and the assembling board B, connecting clamping boards A are separately connected to two ends of the inner side of the assembling board A, the triangular clamping holes are separately formed in the connecting clamping boards A, two connecting clamping boards B are separately connected to two ends of the inner side of the assembling board B, and two rows of vertically arranged triangular clamping blocks are arranged on the connecting clamping boards B. By changing the clamping positions of the triangular clamping blocks and the triangular clamping holes, the separation distance between the assembling board A and the assembling board B is adjusted, so that the thickness of a poured concrete wall is adjusted. A reinforcement cage insertion frame is added structurally, too, so that each insertedreinforcement cage G is prevented from inclining to deform as concrete is filled and poured, and normal construction is facilitated.

Description

Technical field[0001]The invention belongs to the technical field of building exterior wall panels, and more specifically, relates to a fabricated building composite exterior wall panel structure.Background technique[0002]With the development of my country's economic construction, my country's energy demand is growing rapidly, and at the same time primary energy is declining. Energy issues have become a key issue affecting the sustainable development of my country's economy. In northern my country, building energy consumption accounts for more than 20% of all energy consumption. Therefore, the state proposes to promote building energy conservation, vigorously develop energy-saving buildings, and promote strict implementation of the design standard of 50% energy-saving in new residential and public buildings. Among them, the thermal energy loss of the envelope structure of residential and public buildings is relatively large, and the wall of the envelope structure occupies a large sh...

Problems solved by technology

[0005] In order to solve the above technical problems, the present invention provides an assembled building composite exterior wall panel structure to solve the problem that the spacing inside the foam is mostly fixed and cannot be adjusted. The outside of the foam board needs to use cement to paste the decorative board, which wastes time and maintenance. It is more troublesome to replace, and when building a house with foam materials, the bundled steel cage frame inserted into the foundation through the steel frame interspersed frame has a loose relationship with the steel frame interspersed frame, and when the external cement is filled into the foam wall panel. These steel cages are easy to be separated from the steel frame interspersed frame installed on the inner wall of the foam board, and repeated straightening of the steel frame will affect the construction progress
