Description

Technical Field

[0001] The utility model relates to the technical field of cantilever buildings, in particular to a large-span cantilever structure template support connector. Background Art

[0002] With the rapid development of the construction industry, buildings have shown the characteristics of peculiar shapes and complex structures. Existing tower structures are often designed with high-altitude large-span cantilevered building structures. Large-span cantilevered structures refer to buildings with very large span structures. They mainly refer to an effect achieved by building components using other structural designs. Part or all of the building has no support below, giving people a visual effect of being suspended in the air, and is mainly subjected to lateral forces.

[0003] Before installing the cantilevered floor slabs of steel structure buildings, formwork is usually used for formwork installation. Since the formwork usually extends outside the main structure, stable support of the formwork during the pouring process is the key to construction. Existing large-span cantilevered components are often supported by ground-based scaffolding and cantilevered I-beams. However, this bottom formwork support method has the disadvantages of long construction period, low construction efficiency and complex operation, and requires workers to have rich experience.

[0009] Preferably, the adjusting member is located at a midline position between the first support plate and the second support plate.

[0010] Through the above technical solution, the adjustment member is set at the midline position between the support plates to ensure that the supporting force is evenly distributed in the structure to reduce stress concentration, improve the overall stability and safety, and increase the scope of application of the device by adjusting the distance between the first support plate and the second support plate.

It has high flexibility, and the friction brought by the anti-slip grooves effectively prevents the support from sliding during use and causing the bolts to loosen, thereby improving the stability and safety of the support structure. The telescopic fixing rod provides additional supporting force for adjusting the support, further increasing the safety of the device.

[0014] Preferably, a steel beam is overlapped on the upper surface of the first support plate and the second support plate, and the first support plate and the second support plate fix the steel beam via a plurality of clamping plates.

[0028] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways than those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification. The present invention is further described in detail below with reference to the accompanying drawings.

[0029] Example 1: A large-span cantilever structure formwork support connector, such as Figure 1-6 The cam 14 is provided with a plurality of brackets 13 and a plurality of support plates 14, wherein the bracket 14 has a plurality of tabs 13 and a plurality of support plates 14. The bracket 14 is provided with a plurality of brackets 13 and a plurality of support plates 14. The bracket 14 is provided with a plurality of brackets 13 and a plurality of support plates 14. The bracket 14 is provided with a plurality of brackets 13 and a plurality of support plates 14. The bracket 14 is provided with a plurality of brackets 13 and a plurality of support plates 14. The bracket 14 is provided with a plurality of brackets 13 and a plurality of support plates 14. The plate 13 is connected by bolts and can be adjusted by tightening and loosening. One end of the adjusting support 3 can be detachably mounted on the lower surface of the first support plate 11. The first support plate 11 and the second support plate 12 have the same installation structure. The distance between the first support plate 11 and the second support plate 12 can be adjusted by adjusting the connection component 2, so that the device can adapt to supports of different sizes, increasing its scope of application and flexibility. The use of a detachable adjustable support 3 makes the disassembly and installation process of the device simpler. The installation and disassembly are completed by bolt connection and tightening and loosening, without the need for complicated operations, reducing the complexity of the operation and helping to save time and labor costs. The first support plate 11 and the second support plate 12 are pressed against the wall end and are provided with anti-slip grooves 5. The end of the supporting top plate 1 away from the adjusting connection component 2 can be detachably mounted on the wall 0. The first support plate 11 and the second support plate 12 are fixed to the wall 0 by bolts. After the cantilever structure is cast, the holes caused by the fixation are repaired.

[0030] The adjusting connection assembly 2 includes an adjusting piece 21, a screw 22 and a threaded barrel 23. The two threaded barrels 23 are respectively fixedly mounted on the lower surfaces of the first support plate 11 and the second support plate 12. The screw 22 is threadedly connected to the two threaded barrels 23. The adjusting piece 21 is fixedly connected to the middle of the screw 22. The adjusting piece 21 is located at the midline position between the first support plate 11 and the second support plate 12. By introducing the adjusting piece 21, the screw 22 and the threaded barrel 23, the internal threads of the two threaded barrels 23 are in opposite directions, and the screw 22 is a double-headed screw 22. By screwing the adjusting piece 21, the first support plate 11 and the second support plate 12 can be moved inward and outward, achieving more precise adjustment, so that workers can adjust the position of the first support plate 11 and the second support plate 12 as needed to ensure that the distance between the support top plate 1 and the supported object reaches the optimal state. The adjusting piece 21 is located at the midline position between the first support plate 11 and the second support plate 12, so that the adjusting piece 21 is adjusted at the center position of the entire support structure to ensure symmetry and balance and maintain the overall stability of the support structure.

[0031] The adjustable support member 3 includes a sleeve-type threaded telescopic rod 31 and a mounting seat 32. The two mounting seats 32 are respectively rotatably mounted on the two ends of the sleeve-type threaded telescopic rod 31. The two mounting seats 32 are respectively detachably mounted on the wall 0 and the support top plate 1. The mounting seat 32 is provided with anti-slip grooves 5. The end of the sleeve-type threaded telescopic rod 31 close to the wall 0 is provided with a telescopic fixing rod 4. The telescopic fixing rod 4 and the sleeve-type threaded telescopic rod 31 are fixed with a hexagon socket bolt 6. The angle of the telescopic fixing rod 4 is adjusted by removing the hexagon socket bolt 6. The hexagon socket bolt 6 can effectively resist earthquakes. The telescopic fixing rod 4 can be telescopically adjusted until it is fixed to the wall 0, further increasing the supporting force for the adjustable support member 3 and ensuring safe support. The rotatable mounting seat 32 cooperates with the sleeve-type threaded telescopic rod 31 to make the installation of the adjustable support member 3 more flexible. Different installation positions can be selected as needed to adapt to different support structures and space requirements.

[0032] like Figure 5 As shown, the upper surfaces of the first support plate 11 and the second support plate 12 are overlapped with the steel beam 7, and the first support plate 11 and the second support plate 12 are fixed to the steel beam 7 by a plurality of clamping plates 14. By adjusting the bolts on the ear plate 13, the clamping plates 14 can clamp the steel beams 7 of different sizes, which can effectively maintain the stability and adaptability of the supporting structure, and is relatively easy to disassemble and replace, thereby improving construction efficiency. After the floor slab is poured and the demoulding conditions are met, it is convenient to dismantle.

[0033] Working principle: Fix and install the adjusting support members 3 on the lower surfaces of the first support plate 11 and the second support plate 12 in the supporting top plate 1 respectively, and further adjust the distance between the first support plate 11 and the second support plate 12 according to the size of the steel beam 7. After the distance adjustment is completed, further start to adjust the angle of the sleeve-type threaded telescopic rod 31 and the mounting seat 32 in the adjusting support member 3 until it adapts to the installation environment, and then fix the mounting seat 32 at the other end to the wall 0 to complete the installation of the device, so that the first support plate 11 and the second support plate 12 are forced to abut against the wall 0 and fixed thereto, and the upper surface abuts against the steel beam 7, and further adjust the length of the telescopic fixing rod 4 until it is completely abutted and fixed to the wall 0 to add additional supporting force to the device, and further adjust the bolts at each ear plate 13 so that the clamping plate 14 clamps the steel beam 7, thereby fixing the supporting top plate 1 and the steel beam 7 to complete the support, and dismantle the patching after the pouring is completed.

[0034] Example 2: Compared with Example 1, the further improvement of this example is: Figure 6 As shown, the template 8 is overlapped on the upper surface of the first support plate 11 and the second support plate 12, and the template 8 is fixed to the first support plate 11 and the second support plate 12 by screws. When the support body is a flat plate such as the template 8, it is only necessary to remove the clamping plate 14 and drive the screws into the threaded holes of the ear plate 13 to complete the fixation of the template 8.
