[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0019] Please see Figure 1-2 This utility model provides a technical solution:
[0020] In this technical solution, a modular fixing plate includes a building formwork 1 and a plate body 2. The upper wall of the building formwork 1 is provided with a main threaded hole 3, and the lower wall of the plate body 2 is provided with a connecting groove 4. The building formwork 1 can be inserted into the connecting groove 4. The upper wall of the plate body 2 is provided with a positioning groove 5, and a bolt 6 is inserted and installed in the positioning groove 5. The bolt 6 can be screwed into the main threaded hole 3 through the positioning groove 5 through the side wall of the plate body 2.
[0021] The positioning groove 5 has an elliptical cross-section. The bolt 6 includes a bolt body 61, a pressure ring 62, a wedge 63, and a connecting hole 64. The bolt body 61 is inserted into the positioning groove 5. The upper wall of the wedge 63 has a connecting hole 64. The wedge 63 is sleeved on the outside of the bolt body 61 through the connecting hole 64. The pressure ring 62 is installed below the bolt head of the bolt body 61. The pressure ring 62 can fit against the upper wall of the wedge 63. The wedge 63 can be inserted into the positioning groove 5.
[0022] In this technical solution, by setting a wedge 63 on the outside of the bolt body 61, the wedge 63 will continuously insert into the positioning groove 5 during the tightening of the bolt body 61, causing the plate 2 to push towards one side of the building formwork 1, thereby reducing the gap between the plate 2 and the building formwork 1 until it disappears. This prevents concrete from entering the gap between the plate 2 and the building formwork 1 during the later pouring of concrete, thus affecting the forming effect of the building wall.
[0023] The pressure ring 62 can press the wedge 63 to prevent the wedge 63 from tilting. At the same time, the wedge 63 is sleeved on the bolt body 61 through the connecting hole 64, so it does not need to rotate with the bolt body 61.
[0024] In some technical solutions, the upper wall of the building formwork 1 is provided with a secondary threaded hole 7, and the upper wall of the plate 2 is provided with a through groove 8. A fastening bolt 9 is inserted into the through groove 8 and screwed into the secondary threaded hole 7.
[0025] In this technical solution, in order to improve the stability of the device after assembly, the device is also equipped with fastening bolts 9 to further fix the plate 2 and prevent the plate 2 from shifting or falling off the building formwork 1.
[0026] In some technical solutions, a rubber pad 10 is fitted to the side wall of the building formwork 1, and the rubber pad 10 can fit against the side wall of the connecting groove 4.
[0027] In this technical solution, the rubber pad 10 can fit tightly against the side wall of the connecting groove 4 after the building formwork 1 and the plate 2 are assembled, thereby sealing the gap at the connection and preventing concrete from entering during pouring.
[0028] In some technical solutions, a rubber ring 11 is fitted to the lower wall of the pressure ring 62. The rubber ring 11 can be sleeved on the outside of the wedge block 63 and can be fitted to the upper wall of the plate 2.
[0029] In this technical solution, the rubber ring 11 can protect the wedge 63 and the bolt body 61, preventing the bolt body 61 from rusting and the wedge 63 from aging and cracking.
[0030] In some technical solutions, a protective sleeve 12 is fitted on the outside of the fastening bolt 9. The protective sleeve 12 is made of rubber and can fit against the upper wall of the plate 2.
[0031] In this technical solution, the protective sleeve 12 is used to shield and protect the fastening bolt 9, so as to prevent the fastening bolt 9 from rusting and affecting the disassembly of the device later.
[0032] In some technical solutions, the side wall of the fastening bolt 9 is provided with a groove 13, the cross section of the groove 13 is annular, and the inner side wall of the protective sleeve 12 is provided with a protrusion 14, which can be inserted into the groove 13.
[0033] In this technical solution, the protective sleeve 12 can be prevented from falling off the fastening bolt 9 by the cooperation of the protrusion 14 and the slot 13.
[0034] Working principle: When assembling this device, first place the plate 2 outside the building formwork 1 and make the building formwork 1 fit into the connecting groove 4. At this time, the positioning groove 5 corresponds to the main threaded hole 3, and the through groove 8 corresponds to the secondary threaded hole 7. Then, insert the bolt body 61 into the positioning groove 5 and screw it into the main threaded hole 3. During the tightening of the bolt body 61, the wedge 63 will be continuously inserted into the positioning groove 5, causing it to push the plate 2 to one side of the building formwork 1, thereby reducing the gap between the plate 2 and the building formwork 1 until it disappears. This prevents concrete from entering the gap between the plate 2 and the building formwork 1 during the later pouring of concrete, thus affecting the forming effect of the building wall.
[0035] After the bolt body 61 is tightened, the fastening bolt 9 can be screwed into the secondary threaded hole 7 through the through groove 8 through the lower wall of the plate 2 to fix the plate 2 for a second time. Then, the protective sleeve 12 can be put on the outside of the fastening bolt 9.
