Description

Technical Field

[0001] The invention relates to the technical field of building materials, and in particular to an assembled lightweight aggregate fireproof and heat-insulating integrated wall panel. Background Art

[0002] The contribution rate of the building envelope structure to energy conservation in general residential buildings accounts for 50% to 60% of the energy conservation index, and that of public buildings is less than 50%. Among them, the energy consumption of the exterior wall is the most important part of the energy consumption of the exterior wall structure. In order to achieve the energy-saving standards for exterior walls in areas with hot summers and cold winters, insulation of the exterior walls is the top priority of building energy conservation.

[0003] In the existing technology, in order to solve the cold bridge problem, the exterior wall insulation layer is staggered and spliced ​​between two layers of insulation boards, and the two layers of insulation boards need to be bonded. However, from the perspective of engineering application, this bonding strength is insufficient and cannot meet the JGJ144-2019 exterior wall insulation engineering technical standard, so it is gradually eliminated.

The anchor rod is embedded in the lightweight aggregate concrete, and the anchor rod and the lightweight aggregate concrete are integrated by casting. The steel bar passes through the two side surfaces of the lightweight aggregate concrete, and the steel bar has protruding parts on both side surfaces of the lightweight aggregate concrete. The length direction of the steel bar is consistent with the splicing direction of the formwork body.

[0006] Preferably, the length of the integrated composite insulation board is 1200 mm, the width of the integrated composite insulation board is 900 mm, and the sum of the thicknesses of the integrated composite insulation board, the bonding layer, the protective layer, and the lightweight aggregate concrete is 280 mm.

It is only necessary to connect the protruding steel bars of each assembled lightweight aggregate fireproof and thermal insulation integrated wall panel together, which changes the previous on-site construction to centralized factory production, reduces the on-site construction volume, and reduces the construction time.

[0017] (2) The upper and lower templates of the template body are cut from a whole piece of insulation board, so there is no problem of bonding the upper and lower templates. This fundamentally solves the cold bridge problem caused by bonding the two layers of insulation boards in the prior art and meets the technical standards for external wall insulation engineering.

[0018] (3) In the design of the joints between the formwork bodies, the upper and lower formworks of the two adjacent formwork bodies are connected horizontally and vertically to form an insulation layer, forming a horizontal and vertical Z-shaped structural joint, which avoids the gap leakage and thermal bridge problems caused by plaster hanging and assembly displacement at the straight edge joints that often occur in actual construction.

[0019] (4) The design of the horizontal and vertical Z-shaped openings around the formwork body not only realizes the closed-cell structure on the surface, effectively improves the thermal insulation performance by more than 20%, improves the dimensional stability by 0.1%, but also completely solves the problems of slurry leakage and cold bridges in the joints.
