Description

Technical Field

[0001] The utility model relates to the technical field of prefabricated slab brick fetal membranes, in particular to a thin-wall prefabricated slab brick fetal membrane fixing device. Background Art

[0002] In foundation engineering construction, most projects currently still use traditional brick membrane methods, which is time-consuming and labor-intensive. However, some projects have begun to apply new prefabricated board membrane technology. Due to its integrity, it greatly reduces the amount of labor and does not require plastering. However, due to its own poor stability, how to efficiently and conveniently reinforce the structure is currently a pain point.

[0003] Before backfilling the foundation and ground beam, wood, steel pipes and other materials are generally used to form a support to prevent the side pressure of the prefabricated finished board from causing the board to move sideways, resulting in structural size deviation. Most of the existing support methods use three wood blocks in an H shape to support the prefabricated board membrane, but it is difficult for the wood blocks to achieve a horizontal support, so the subsequent side pressure of the backfill can easily cause the board to move sideways, which brings inconvenience to people when using it. Utility Model Content

[0004] The technical problems to be solved by the utility model are as follows:

[0005] The problem is that most of the supporting methods in the prior art use three wooden beams in an H shape to support the prefabricated board membrane, but since it is difficult for the wooden beams to support the prefabricated board in a horizontal state, the subsequent backfilling side pressure can easily cause the board to move sideways, causing inconvenience to people when using it.

[0006] The purpose of the utility model can be achieved through the following technical solutions:

[0009] Furthermore, a contraction component is installed at the bottom end of the first extrusion plate and the second extrusion plate. The contraction component includes a sleeve plate. A sliding plate is slidably connected inside one end of the sleeve plate. A third contraction spring is symmetrically fixedly connected between the inside of the sleeve plate and the sliding plate.

[0010] Furthermore, a fixed knob is installed on one side of the rotating seat, and one end of the fixed knob passes through the rotating seat and is fixedly connected with the extrusion rod.

The end of the extrusion rod 206 away from the rotating seat 204 is extruded and connected with the stopper 205. Through the upper and lower support methods, the stability of the prefabricated board membrane is greatly improved, and the pressure on the back-soil side of the prefabricated finished board causes the board to move sideways, causing structural dimensional deviation. A fixing knob 207 is installed on one side of the rotating seat 204, and one end of the fixing knob 207 passes through the rotating seat 204 and is fixedly connected with the extrusion rod 206. Through the design of the fixing knob 207, the extrusion rod 206 after support is fixed to prevent displacement.

[0027] The working principle of this utility model:

[0028] By placing the first extrusion plate 1 and the second extrusion plate 101 between the prefabricated board membrane, the movement of the screw 202 is driven by rotating the sleeve 201, so as to push the second extrusion plate 101 to fit with the prefabricated board membrane, thereby completing the first support, and then rotating the extrusion rod 206 to squeeze and support the block 205 according to the spacing between the prefabricated board membranes, so as to greatly improve the stability of the prefabricated board membrane through the upper and lower support methods, and avoid the lateral displacement of the prefabricated finished board due to the pressure on the soil side, resulting in structural dimensional deviation. The design of the fixing knob 207 fixes the extrusion rod 206 after support to prevent displacement. When the sleeve 201 drives the movement of the screw 202, the sliding plate 402 slides inside the sleeve 401, and the third contraction spring 403 contracts. The contractility of the third contraction spring 403 provides stability for the contraction of the auxiliary screw 202.

[0029] The movement of the push plate 303 is driven by pulling the sliding rod 307, and the movement of the push plate 303 causes the plug block 304 to disengage from the slot 305. At this time, the first contraction spring 306 contracts, thereby releasing the fixing restriction on the sleeve 201, which is convenient for subsequent rotation operations. When the sleeve 201 needs to be rotated, the top of the limiting rod 311 is clamped and fixedly connected with the limiting hole 308, so that the plug block 304 is no longer clamped and connected with the slot 305, which is convenient for subsequent rotation operations. The operation is simple and convenient, and the connecting plate 301 can be quickly fixed and separated to meet people's usage needs.
