Building external wall insulation AAC composite wallboard structure assembling method based on structural column

Abstract

The invention discloses a building outer wall heat preservation AAC composite wallboard construction assembly method based on a structural column. The method comprises the steps that firstly, a composite beam, the structural column, a heat preservation AAC composite wallboard and a water stop reverse ridge are prefabricated; 2, assembling a structural column; thirdly, a waterproof reverse ridge is assembled; 4, assembling the thermal insulation AAC laminated wallboards; fifthly, the upper cross rod is dismantled; sixthly, square steel is installed; seventhly, the vertical rods and the lower transverse rods are dismantled; 8, filling the positioning groove; 9, assembling an upper side superposed beam; and tenthly, the second step to the ninth step are circulated till assembly is completed. According to the prefabricated structural column, the waterproof reverse ridge and the heat preservation AAC composite wallboard, the multiple positioning grooves are formed in the reverse ridge protruding block, the hoisting groove is formed in the bottom of the heat preservation AAC composite wallboard in the width direction so that a hoisting tool can be conveniently installed, and the falling position of the hoisting tool is positioned through the positioning grooves; the thermal insulation AAC composite wallboard is hoisted, meanwhile, accurate assembly of the external wall thermal insulation AAC composite wallboard and the waterproof reverse ridge is guaranteed, and an assembly type structure and a main body are constructed at the same time.

Problems solved by technology

[0002] The current design and adoption of the technical specification for building self-insulation exterior wall system is "Technical Specification for Lightweight Autoclaved Sand Aerated Concrete Blocks and Plates DBJ61 / T89-2014", and the standard drawing is "Autoclaved Lightweight Sand Aerated Concrete (AAC) Block and plate structural construction 06CGC01", "Autoclaved lightweight sand aerated concrete (AAC) block and plate structural construction 06CJC05", the above-mentioned standards have the following problems: First, the thickness of the thermal insulation wall panels that do not involve design calculations is insufficient how to solve the problem; secondly, the original drawing concentrated method is to carry out the construction after the construction of the main structure, and there is no relevant structure and construction technology suitable for prefabricated buildings

[0003] At present, the structure and construction method of AAC laminated wall panels for external wall insulation suitable for frame structures have been studied, and the single-layer AAC panels do not meet the designed self-insulation wall thickness, and there is no overlap in the national standard atlas and industry regulations. Fixing of composite wall panels and anti-seismic anchor pull methods, national standard atlases and industry regulations exist in the existing single-layer thermal insulation wall panel methods that the internal and external connections of the connectors exist. When there is a large temperature difference between indoor and outdoor, thermal bridge effects will occur, etc. question

However, the relevant structure and construction method are only applicable to the frame structure, which needs to be constructed separately after the main body is completed, which does not meet the needs of simultaneous construction with the main body in the prefabricated structure
