Description

Technical Field

[0001] The present invention relates to the technical field of thermal insulation walls, specifically to a unit-assembled steel mesh formwork sandwich thermal insulation wall. Background Art

[0002] A sandwich thermal insulation wall is a composite wall formed by sandwiching thermal insulation materials between two walls (inner leaf wall and outer leaf wall). The inner leaf wall and the outer leaf wall are generally made of reinforced concrete structure and are connected by connecting pieces in the middle. It is divided into integral prefabricated type and unit-assembled type. The unit-assembled type is to split the sandwich thermal insulation wall into several smaller unit components and assemble them on site according to the design requirements. This method is suitable for projects with complex building shapes and special design requirements, and can flexibly combine units according to specific situations to meet different building needs.

[0003] The prior art does not have a structure for flexibly connecting the thermal insulation board and the side keel and strengthening the connection between the thermal insulation wall and the casting wall when in use. When the existing unit-assembled sandwich thermal insulation wall is in use, an L-shaped connecting plate is mostly used to connect the thermal insulation board and the side keel. If the hole opening position on the side keel deviates from the predetermined hole opening position, the original-sized L-shaped connecting plate cannot connect the side keel and the thermal insulation board. Moreover, if the customer customizes side keels and casting layers with special thicknesses, the single-sized L-shaped connecting plate cannot connect to the hole opening positions on the non-standard keels. At the same time, when the connecting pieces between the existing thermal insulation wall and the casting layer are in use, because the multiple connecting pieces are not connected to each other and the outer ends are relatively small, there is a certain probability that the connecting pieces will be pulled out of the concrete layer during hoisting and moving after the concrete layer is poured. Based on the deficiencies of the existing technology, the present invention designs a unit-assembled steel mesh formwork sandwich thermal insulation wall. Summary of the Invention

[0034] Working principle: When the unit assembled steel mesh formwork sandwich insulation wall is in use, in the initial state, first, the corrugated steel mesh 102 is fixedly connected to both sides of the insulation board body 1. The tie bars 104 are inserted between the two groups of side keels 101 to facilitate the pouring of the mortar layer 105. The first fixing bolt 302 and the second fixing bolt 309 are installed on the L-shaped fixing plate 301 arranged between the insulation board body 1 and the side keel 101.
