[0029] The following is combined with Figure 1-4 This application is described in further detail.

[0030] The embodiment of the present application discloses a large span cantilever structure formwork support connector. Figure 1A large-span cantilever structure formwork support connector includes a first support plate 1, a second support plate 2, and a support member 3. One end of the first support plate 1 is hinged to one end of the second support plate 2, and the other end of the first support plate 1 is provided with a first support portion 11. The other end of the second support plate 2 is hinged to one end of the support member 3.

[0031] When it is necessary to use the large-span cantilever structure formwork support connector disclosed in this embodiment, the first support plate 1 and the second support plate 2 are unfolded, and then the end of the support member 3 away from the hinged connection with the second support plate 2 is used to abut against the first support part 11, thereby ultimately achieving the purpose of supporting the first support plate 1. A formwork is placed on the first support plate 1, and the second support plate 2 is abutted against the wall, so that the formwork can protrude from the wall. A steel frame is placed in the formwork, concrete is poured, etc., and after the concrete solidifies, the large-span cantilever structure can be manufactured.

[0032] After use, the support member 3 is separated from the first support portion 11, and the hinge structure of the support member 3 and the second support plate 2 is folded, and then the first support plate 1 and the second support plate 2 are folded to achieve storage.

[0033] The hinged structure can be used by the staff to quickly unfold and support it when in use, and fold it up after use, which is convenient for placement and recycling, and after folding, it reduces the occupied space.

[0034] Reference Figure 2 and Figure 3 The structure of the hinged connection between the first support plate 1 and the second support plate 2 is specifically as follows: a first sleeve 12 is fixed to the end of the first support plate 1, and a second sleeve 23 is fixed to the end of the second support plate 2. When the two are hinged, a connecting rod 4 is inserted into the first sleeve 12 and the second sleeve 23. The connecting rod 4 is inserted into the first sleeve 12 and the second sleeve 23 at the same time, and the connecting rod 4 can rotate to realize the hinged connection of the first support plate 1 and the second support plate 2.

[0035] Both ends of the connecting rod 4 are provided with third through-holes 41, into which both third through-holes 41 are inserted. When the connecting rod 4 is inserted into the first sleeve 12 and the second sleeve 23, the limiting members 5 are also inserted into the third through-holes 41, thereby limiting the position of the connecting rod 4 and reducing the possibility of the connecting rod 4 falling off during the folding and unfolding of the first support plate 1 and the second support plate 2. If the first support plate 1 or the second support plate 2 is damaged, the limiting members 5 and the connecting rod 4 can be removed for repair or replacement, providing high convenience.

[0036] Reference Figure 4A fixing rod 21 is provided at the hinged portion of the second support plate 2 and the support member 3. The ends of the fixing rod 21 are provided with threads. A second through hole 22 is correspondingly opened on the second support plate 2. The portion of the fixing rod 21 where no threads are provided is thicker than the second through hole 22. The end of the fixing rod 21 passes through the second through hole 22. A nut 211 is provided at the end of the fixing rod 21. By tightening the nut 211, the fixing rod 21 can be fixed to the second support plate 2.

[0037] Reference Figure 2 The support member 3 includes a hinged rod 31 and a support rod 32. One end of the hinged rod 31 is used to be hinged to the fixed rod 21, that is, a first through hole 311 is provided at one end of the hinged rod 31, and the fixed rod 21 is passed through the first through hole 311. The hinged rod 31 is hollow and provided with an internal thread, and the support rod 32 is provided with an external thread. A socket 321 is also provided at one end of the support rod 32, and the support rod 32 is threadedly connected to the hinged rod 31.

[0038] When support is needed using the support member 3, the support rod 32 is rotated to adjust the overall length of the support member 3. After the length is adjusted to the appropriate length, the support member is brought into contact with the first support portion 11, thereby achieving the purpose of supporting the first support plate 1 by the support member 3. By adjusting the length of the support member 3, the angle of the first support plate 1 can be adjusted to suit different usage requirements. In addition, if the support member 3 is damaged, the fixing rod 21 can be removed and the support member 3 can be replaced without having to replace the entire support member, which can reduce usage costs.

[0039] Reference Figure 2 and Figure 3 Both end faces of the first support plate 1 are provided with series units 6. When a wider support area is required, multiple large-span cantilever structure formwork support connectors disclosed in this embodiment can be placed side by side, and the adjacent first support plates 1 can be connected by using the series units 6, so as to provide more stable support.

[0040] The series connection unit 6 includes a threaded hole 61, a bolt 62, and a series connection member 63. The threaded hole 61 is located on the end surface of the first support plate 1. At least two threaded holes 61 are provided on each end surface, and in this embodiment, two are provided. The bolt 62 passes through the series connection member 63 and is tightened in the threaded hole 61 to connect adjacent first support plates 1.

[0041] The implementation principle of a large-span cantilever structure formwork support connector in an embodiment of the present application is as follows: the first support plate 1 and the second support plate 2 are hinged, and the hinged structure is used to enable the first support plate 1 and the second support plate 2 to be unfolded and folded. When in use, both are unfolded, and the support member 3 is used to support the first support plate 1, so that the first support plate 1 can support the formwork.

[0042] When using the support member 3 for support, the support rod 32 and the hinged rod 31 are threadedly connected. The length of the support rod 32 extended or retracted can be adjusted by rotating the support rod 32, thereby adjusting the length of the support member 3. After the length of the support member 3 changes, the angle between the first support plate 1 and the second support plate 2 will change. By adjusting the length of the support member 3, it is possible to adapt to different usage requirements and adjust the pitch angle of the template.

[0043] After use, the support member 3 and the second support plate 2 can be hinged together to fold the support member 3, and then the first support plate 1 and the second support plate 2 can be folded. After folding, the space occupied is small, and it is easy to store.

[0044] In the event of damage, the first support plate 1 and the second support plate 2 can be separated by disassembling the plug-in rod 4 and the fixing rod 21, and the support member 3 and the second support plate 2 can be separated. Only the damaged part needs to be replaced, and the entire part does not need to be replaced, which can reduce the cost of use.

[0045] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
