Description

Technical Field

[0002] In the prior art, most of the hanging hole plugging generally uses wooden formwork as the bottom formwork, and the reinforcement method mostly uses steel pipe top support vertical support or iron wire suspension fixation. After the plugging concrete reaches a certain strength, the steel pipe vertical support is removed or the iron wire is cut to remove the bottom formwork. However, the method of using steel pipe top support to support the installation of the formwork or hanging formwork has a small load-bearing capacity and the formwork is not firmly fixed, which is prone to slurry leakage; in addition, when setting up scaffolding for support, there are many procedures and a large workload, which will consume a lot of manpower and increase construction costs. It is also difficult to remove the formwork in the later stage, and the stability is poor. It is not suitable for some horizontal openings with large heights. Although using iron wire to lift upward can avoid the complicated steel pipe top return, the bottom formwork will leak if the iron wire is not tied firmly, and it cannot withstand large loads. After the horizontal hole is plugged, the iron wire will rust and there will inevitably be a hidden danger of water leakage. Therefore, it is necessary to provide a new type of hanging hole support device to solve the above problems. Utility Model Content

[0028] See also Figure 1-6 The first embodiment of the utility model provides a hanging hole support device, including a first support frame 1, a second support frame 2 and a connecting rod 3. The first support frame 1 is provided with a first through hole 11, and the second support frame 2 is provided with a second through hole 21. The connecting rod 3 is penetrated by the first through hole 11 and the second through hole 21. The first support frame 1 and the second support frame 2 are arranged along the axial direction of the connecting rod 3. By moving the first support frame 1 and the second support frame 2 along the axial direction of the connecting rod 3 to adjust the distance between the first support frame 1 and the second support frame 2, the device can be suitable for hanging holes 4 of different depths.

[0029] In this embodiment, the connecting rod 3 and the first through hole 11 and the second through hole 21 are all arranged with clearance fit, so that the first support frame 1 and the second support frame 2 can move along the axial direction of the connecting rod 3, which is convenient for use.

[0030] The connecting rod 3 is also screwed with two nuts 31, and the two nuts 31 are respectively located at the two outer sides of the first support frame 1 and the second support frame 2; when in use, the first support frame 1 and the second support frame 2 are respectively located at the two ends of the hanging hole 4, and the connecting rod 3 is inserted into the hanging hole 4. By screwing the nuts 31, the screwing position of the connecting rod 3 and the nuts 31 can be adjusted, so that the first support frame 1 and the second support frame 2 are clamped between the two nuts 31, and the hanging hole 4 is clamped between the first support frame 1 and the second support frame 2. When disassembling and assembling the device, only the nuts 31 need to be screwed to adjust the tightness, which is convenient for disassembly and assembly; and the screw connection method is relatively firm, even if heavy concrete is placed between the first support frame 1 and the second support frame 2, the first support frame 1 and the second support frame 2 can be firmly stuck at the two ends of the hanging hole 4, and it is not easy to move, thus solving the problem of bearing low load.

[0031] The connecting rod 3 is sleeved with a first sleeve 32, and the first sleeve 32 is located between the first support frame 1 and the second support frame 2. The length of the first sleeve 32 is greater than the depth of the hanging hole 4. After pouring concrete in the hanging hole 4, the concrete can be prevented from adhering to the connecting rod 3, and the connecting rod 3 does not contact the concrete, so that the connecting rod 3 can be removed and reused, and the first support frame 1, the second support frame 2 and the nut 31 can also be reused, thereby reducing construction costs.

[0032] The first sleeve 32 is provided with a water-stop assembly 33. Specifically, the water-stop assembly 33 includes a second sleeve 331 and a water-stop plate 332. The second sleeve 331 is sleeved on the first sleeve 32. The second sleeve 331 is passed through the water-stop plate 332. The water-stop plate 332 can increase the water infiltration path, play a role in water-stopping, and avoid the hidden danger of water seepage.

[0033] The first sleeve 32 and the connecting rod 3 are clearance-fitted, which facilitates the removal of the connecting rod 3 from the first sleeve 32 . The second sleeve 331 and the first sleeve 32 are interference-fitted, which makes the connection between the two more secure and prevents the water stop sheet 332 from falling off.

[0034] The first support frame 1 includes two first fixing rods 12 arranged side by side and with a gap therebetween, and the two first fixing rods 12 are both provided with a first through hole 11. The second support frame 2 includes a support rod 23 and two second fixing rods 22 arranged side by side and with a gap therebetween, and both ends of the support rod 23 are respectively connected to the two second fixing rods 22, and the two second fixing rods 22 are both provided with a second through hole 21. The connecting rod 3 connects the first fixing rod 12 with the second fixing rod 22. The entire support device is a frame formed by connecting rods, which has a simple structure and readily available materials, and is conducive to cost saving.

[0035] The first support frame 1 also includes four fixing blocks 13, each of which is connected to the end of the two first fixing rods 12, and each of the fixing blocks 13 is located on the side of the two first fixing rods 12 facing the second support frame 2. The fixing blocks 13 play a role of raising the height. When the inside of the hanging hole 4 is filled with concrete, the first fixing rods 12 are prevented from contacting with the concrete. After the concrete solidifies, it is convenient to recover the first support frame 1.

[0036] The first fixing rod 12 is welded to the fixing block 13, and the second fixing rod 22 is welded to the supporting rod 23. The welding method ensures that the components are firmly connected and the welding is easy to manufacture.

[0037] The cross sections of the fixing block 13, the first fixing rod 12, the second fixing rod 22 and the supporting rod 23 are all square, and the square arrangement can prevent rolling and mold running.

[0038] The fixing block 13, the first fixing rod 12, the second fixing rod 22 and the supporting rod 23 are all hollow and light in weight, which facilitates subsequent removal after the hanging hole 4 is cast. In addition, the hollow material is affordable, which is conducive to cost saving.

[0039] In this embodiment, the fixing block 13, the first fixing rod 12, the second fixing rod 22 and the supporting rod 23 are all made of steel, and the steel structure is strong and has good stability.

[0040] The second support frame 2 also includes a template 5, which is located on the side of the second fixing rod 22 and the support rod 23 facing the first support frame 1, and the connecting rod 3 is passed through the template 5. When in use, the template 5 covers the bottom end of the hanging hole 4, and the first support frame 1 is located at the top end of the hanging hole 4. The template 5 can provide support for the concrete filled in the hanging hole 4 to shape it.

[0041] In this embodiment, the edge of the template 5 exceeds the second fixing rod 22, avoiding direct contact between the second fixing rod 22 and the concrete, facilitating the subsequent removal of the second fixing rod 22 and the support rod 23, and further facilitating recycling, which is conducive to cost saving.

[0042] See also Figure 7 The second embodiment of the utility model provides a hanging hole support device, which includes a first support frame, a second support frame, a connecting rod and a template, wherein the structures of the first support frame, the second support frame and the template are the same as those of the first embodiment mentioned above and are not repeated here. The difference is that the water stop assembly 6 includes a water stop plate 61, and the first sleeve 7 is passed through the water stop plate 61. The water stop plate 61 is directly connected to the first sleeve 7, and the structure is simpler, which is conducive to cost saving.

[0043] The above is a specific description of the preferred implementation of the utility model, but the invention of the utility model is not limited to the described embodiments. Technical personnel familiar with the field can also make various equivalent deformations or substitutions without violating the spirit of the utility model. These equivalent deformations or substitutions are all included in the scope defined by the claims of this application.
