Description

Technical Field

[0001] The utility model relates to the technical field of basement side wall protection, in particular to a fixing device for a waterproof protection extruded plate for a basement side wall. Background Art

[0002] 1. Brief description of the existing technology

[0003] During the backfill process of the basement side walls, a layer of extruded board is usually added as a protective layer to prevent damage to the side wall waterproofing layer caused by earthwork or mechanical operations. This extruded board is usually directly attached to the outside of the waterproof layer with double-sided tape to achieve the purpose of protecting the side wall waterproofing layer.

[0004] 2. Objective shortcomings of existing technologies

[0005] However, in practice, due to the high soil pressure during sidewall backfill, the double-sided tape-attached extruded panels are often squeezed and detached, resulting in large areas of falling panels. This not only requires additional labor for reinstallation and restoration, increasing construction costs and difficulty, but also poses certain safety risks during the manual restoration process. Furthermore, the frequent falling of extruded panels seriously impacts construction progress and reduces overall project efficiency. Therefore, the existing double-sided tape-attaching method is unable to meet the actual needs of basement sidewall backfill. Utility Model Content

[0039] The following embodiments of the present invention are described in detail with reference to the accompanying drawings. In the absence of conflict, the following embodiments and features in the embodiments may be combined with each other.

[0040] Example 1

[0041] Reference Figure 1-Figure 2 This embodiment provides a fixing device for a waterproof protective extruded board for a basement side wall, which includes:

[0042] Bracket 1, forward pushing mechanism, sleeve 7 and support column 5;

[0043] The bracket 1 includes a front support 101 and a rear support 102. The front support 101 is provided with a forward pushing mechanism and an extension portion. The front end of the extension portion is hinged to the sleeve 7. The sleeve 7 has a first through-hole. The support column 5 is passed through the first through-hole. The forward pushing mechanism is used to push the support column 5 to tilt forward and press against the extruded board.

[0044] The front support 101 and the rear support 102 are welded together or are an integrally formed structure. The front support 101 is vertically arranged or has a certain inclination angle with the vertical plane and the inclination angle is not greater than 30°.

[0045] The extension portion is located under the forward pushing mechanism, and the forward pushing mechanism is used to push the upper part of the support column 5 to tilt forward and press against the extruded plate. When the support column 5 tilts, it may drive the sleeve 7 to tilt together. Since the sleeve 7 has a hinge point due to being hinged to the extension portion, the sleeve 7 rotates around the hinge point and tilts together with the support column 5.

[0046] The provision of the extension portion enables the buttress 5 to be located in front of the forward pushing mechanism.

[0047] The forward pushing mechanism includes a push rod, a push block 4 and a locking member;

[0048] A second through hole is formed on the front pillar 101 , the push rod is passed through the second through hole, and the push block 4 is provided at the front end of the push rod. The push rod is provided with the locking member for locking the push rod and the front pillar 101 .

[0049] Specifically, the push rod is a screw rod 2 , and the locking member is a nut 3 , which is screwed onto the rear end of the screw rod 2 .

[0050] The forward pushing principle of the forward pushing mechanism is: by rotating the screw 2, the screw 2 is screwed forward and pressed against the support column 5, and then the screw 2 continues to rotate forward to push the upper part of the support column 5 to tilt forward, thereby pushing the support column 5.

[0051] In this embodiment, there may be a certain gap between the anti-pillar 5 and the first through-hole. To address this, a threaded hole connected to the first through-hole is opened on the outer side of the sleeve 7, and a fastening bolt 8 is installed in the threaded hole. The fastening bolt 8 is screwed to tighten the anti-pillar 5 and lock the anti-pillar 5. Then, when the front pushing mechanism drives the upper part of the anti-pillar 5 to tilt forward, the sleeve 7 will tilt together with the anti-pillar 5 and rotate around the hinge point.

[0052] In this embodiment, the sleeve 7 and the extension portion can be hinged by a rotating shaft or a hinge. The first through-hole is vertically penetrated, and the second through-hole is front-to-back penetrated.

[0053] In this embodiment, both the extension and the support column 5 can be made of scrap steel bars that are easily available on site. The advantages of adopting this structure are that the materials used are common and easily found on site, allowing for on-site assembly. Leverage is used to push the support column 5 upwards and force its lower portion against the extruded sheet, minimizing damage to the sheet. Furthermore, the support column 5 can be cylindrical, further minimizing damage to the sheet. If the side walls are too high, resulting in the support column 5 being too long and difficult to maintain stability, a counterweight can be added to the bracket 1 to improve stability.

[0054] Practical applications of fixtures:

[0055] The fixing device is installed on the wall or building just above the side wall of the basement (for example, it is installed on the ground of the first floor of the building) through the bracket 1. At the same time, the side wall and the extruded board are located at the rear side of the column 5. Before backfilling, the column 5 is pushed forward by the forward pushing mechanism to tilt the column 5 forward, and at the same time, the lower part of the column 5 is tilted backward and pressed against the extruded board of the side wall of the basement. After the extruded board is pressed and fixed, even if the pressure of the soil is large when the side wall is backfilled, the extruded board will not fall off or fall off. Then the bottom of the side wall can be backfilled first, and the side wall After the backfill at the bottom is completed, loosen the fastening bolts 8, and pull the support column 5 out of the loose soil and lift it up a certain distance or replace it with a shorter support column 5, then reset the forward pushing mechanism so that the bottom of the support column 5 now corresponds to a higher layer of extruded board, and then push the forward pushing mechanism forward again and push the support column 5 so that the bottom of the support column 5 is pressed against the higher layer of extruded board, and so on. By repeating this method, you can backfill from the bottom of the side wall to the top in sequence until all the backfill of the basement side wall is completed, which will not affect the construction progress and overall project efficiency.

[0093] The beneficial effects of the technical solution of the utility model are:

[0094] The present application provides a simple, easy-to-operate device for fixing waterproof extruded panels for basement side walls. Utilizing the principle of leverage, the upper portion of the support column 5 is pushed to press the lower portion against the surface of the extruded panel, thereby achieving a surface retraction effect. This device causes minimal damage to the extruded panel, and the use of a cylindrical structure for the support column 5 can further reduce damage to the panel. If the side wall is too high, causing the support column 5 to be too long and difficult to maintain stability, a counterweight can be added to the bracket 1 to improve stability. After the side wall is backfilled, the fastening bolts 8 on the sleeve 7 are loosened, and the support column 5 can be pulled out of the loose soil and raised or replaced with a shorter support column 5.
