Description

Technical Field

[0001] The present invention relates to the technical field of thermal insulation walls, and specifically to an integral precast embedded 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 of reinforced concrete structure and are connected by connectors in the middle. It is divided into integral precast type and unit assembled type. The integral precast sandwich thermal insulation wall is integrally precast in the factory and then transported to the construction site for integral hoisting and installation, which can effectively reduce the on-site construction time and improve the construction efficiency, especially suitable for large-scale and standardized construction projects.

[0003] The existing technology does not have a structure for adjusting the inner support members of the thermal insulation wall and strengthening the connection stability of the inner connectors when in use. When the existing integral precast thermal insulation wall is being poured, it is necessary to first use support members to connect the two outer plates and the thermal insulation board. However, since most of the support members are of fixed length, when customers need to customize thermal insulation walls with special pouring thicknesses, the support members of fixed length are difficult to meet the requirements. Moreover, the connectors embedded in the thermal insulation board are extremely prone to bending or sliding left and right during use, thereby affecting the positions of both ends of the connectors inside the concrete layers on both sides. Based on the deficiencies of the existing technology, the present invention designs an integral precast embedded sandwich thermal insulation wall. Summary of the Invention

[0031] Please refer to Figures 4-5, the connecting mechanism 2 includes a connecting piece main body 201, a positioning threaded ring 202, a clamping plate 203, a connecting screw 204 and a reinforcing plate 205.

[0032] By providing the connecting piece main body 201, the positioning threaded ring 202 and the clamping plate 203, after the connecting piece main body 201 is fixedly arranged through the thermal insulation board main body 1, while improving the connection stability of the connecting piece main body 201 on the thermal insulation board main body 1, it can prevent the impact of the pouring layer 105 during pouring from causing the connecting piece main body 201 to slip off.

[0033] Working principle: When the integral precast embedded sandwich thermal insulation wall is in use, in the initial state, first, the corrugated steel mesh 102 is fixedly connected to both sides of the thermal insulation board main body 1. There is a thermal insulation strip 101 inserted between the thermal insulation board main body 1 and the thermal insulation strip 101. The thermal insulation strip 101 is connected to the tie bar 104 through the connecting buckle 103, and at the same time, there is an outer protective layer board 106 on the outside, so as to facilitate the pouring of the pouring layer 105. And the two ends of the connecting piece main body 201 inserted through the thermal insulation board main body 1 are connected with a connecting screw 204 and a reinforcing plate 205, and the connecting piece main body 201 is also connected with a positioning threaded ring 202 and a clamping plate 203, so as to fix the position of the connecting piece main body 201 and prevent the connecting piece main body 201 from falling off or tilting during the pouring of the pouring layer 105, which affects the connection effect. At the same time, an adjusting sleeve 303 is sleeved on the positioning cylinder 301 fixedly connected to both sides of the thermal insulation board main body 1. The adjusting sleeve 303 is connected to the connecting nut 311 and the connecting bolt 312 connected to the outer protective layer board 106 through the threaded hole 310, so as to control the pouring thickness of the pouring layer 105 according to the required distance between the thermal insulation board main body 1 and the outer protective layer board 106.

[0034] When it is necessary to control the pouring thickness of the pouring layer 105 as required, first, after the heat preservation strips 101, corrugated steel meshes 102, connecting buckles 103 and tie bars 104 are connected to the main body 1 of the heat preservation board, a plurality of positioning cylinders 301 are inserted through the heat preservation strips 101 from the preset positions and fixed on both sides of the main body 1 of the heat preservation board. Then, loosen the tightening ring 306 so that the inner tightening head 304 slightly expands outward to release the clamping and fixing with the positioning cylinder 301. At this time, under the limitation of the sliding groove 308 and the limit indicating rod 302, pull the adjusting sleeve 303 outward and simultaneously observe the value of the pointer of the limit indicating rod 302 pointing to the scale line 309. After the combined length of the positioning cylinder 301 and the adjusting sleeve 303 reaches the required thickness, tighten the tightening ring 306 again so that the inner tightening head 304 retracts inward to clamp the positioning cylinder 301 and lock the position of the adjusting sleeve 303.

At this time, adjust the position of the main body 201 of the connecting piece so that the exposed lengths on the left and right are equal and continuously screw the positioning threaded rings 202 and the clamping plates 203 until the planes are in contact with both sides of the main body 1 of the heat preservation board to realize the clamping and fixing of the main body 201 of the connecting piece. Finally, screw the two connecting screw rods 204 into the main body 201 of the connecting piece according to the required exposed length. This device is convenient for improving the stability when the main body 201 of the connecting piece is connected to the main body 1 of the heat preservation board.
