[0002] With the rapid development of the construction industry and to meet people's requirements for the visual effects of building exteriors, the roof shapes of many high-rise and super-high-rise residential buildings are becoming increasingly complex and diverse. Even many cantilever structures of the out-of-roof framework layers extend beyond the building plane of the roof. However, such designs have caused great difficulties in construction.

[0003] One end of the cantilever slab is embedded in or cast on a support, and the other end extends beyond the support. At present, when erecting an outdoor cantilever slab, a support device is usually set at the bottom of the cantilever slab to enhance the stability of the cantilever slab. However, the current conventional method is to use steel pipes or disk locks to erect a floor full hall support system for the construction of high-altitude reinforced concrete cantilever slabs. The overall amount of materials is large, which increases the construction duration and is not convenient for turnover use. Therefore, a reusable cantilever support structure is designed.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0023] As Figures 1-4As shown in the figure, the utility model provides a turnover type cantilever support structure, which includes a connecting beam 100, a support frame 200, a diagonal bracing beam 300 and a strengthening component 400. The support frame 200 is arranged at the bottom of the connecting beam 100. The support frame 200 includes two support beams 201 and two connecting rods 202. The two support beams 201 are respectively arranged on both sides of the bottom of the connecting beam 100. The two connecting rods 202 are respectively arranged between the support beam 201 and the connecting beam 100. The diagonal bracing beam 300 is arranged at the front side of the support beam 201. The strengthening component 400 is arranged between the diagonal bracing beam 300 and the support beam 201. The strengthening component 400 includes a cross bar 401, a bottom bar 402, a mounting seat 403 and a fixing rod 404. The bottom bar 402 is arranged below the cross bar 401. The mounting seats 403 are respectively arranged at the rear sides of the cross bar 401 and the bottom bar 402. The fixing rod 404 is arranged between the bottom bar 402 and the cross bar 401.

[0024] Further, in this embodiment, connecting beams 100 are arranged at the upper ends of both the support beam 201 and the diagonal bracing beam 300. Connecting plates 204 adapted to the connecting beam 100 are fixed at the upper ends of both the support beam 201 and the diagonal bracing beam 300. The connecting plates 204 are bolted to the connecting beam 100. The support beam 201 and the diagonal bracing beam 300 are installed at the lower end of the connecting beam 100 through the connecting plates 204 to support the connecting beam 100.

[0025] In this embodiment, both ends of the connecting rod 202 are bolted to the support beam 201 and the connecting beam 100 respectively, forming a triangle. A cross beam 203 is screwed between the bottoms of the two support beams 201. The connection between the support beam 201 and the connecting beam 100 is strengthened through the connecting rod 202, and the bottoms of the two support beams 201 are stabilized through the cross beam 203.

[0026] In this embodiment, mounting seats 403 are arranged at the rear ends of both the cross bar 401 and the bottom bar 402. The mounting seats 403 are welded to the support beam 201. The fixing rod 404 penetrates through the cross bar 401 and the bottom bar 402 and is rotatably connected to the cross bar 401 and the bottom bar 402. The rear ends of the cross bar 401 and the bottom bar 402 are connected to the mounting seats 403 through the fixing rod 404, and the cross bar 401 and the bottom bar 402 can synchronously adjust the use direction outside the fixing rod 404.

[0027] In this embodiment, a fastening block 405 is fixed on the upper side of the mounting seat 403. The fastening block 405 is in threaded cooperation with both ends of the fixing rod 404. The bottom bar 402 is of a bent design. The front end of the bottom bar 402 is welded to the bottom of the cross bar 401. The front end of the cross bar 401 is bolted to the diagonal bracing beam 300. The fixing rod 404 is fixed through the fastening block 405 to realize the connection between the bottom bar 402 and the cross bar 401 and the mounting seat 403. The shape of the bottom bar 402 facilitates its support for the cross bar 401.

[0028] In this embodiment, there is a gap between the bottom rod 402 and the cross rod 401. A support rod 406 is arranged in the gap. The support rod 406 is bolted to the bottom rod 402 and the cross rod 401 respectively. The gap between the bottom rod 402 and the cross rod 401 is reinforced by the support rod 406, and the supporting force of the bottom rod 402 on the cross rod 401 is improved.

[0029] In this embodiment, a connecting rod 500 is arranged between the support beam 201 and the diagonal bracing beam 300. Connecting blocks 501 are arranged on the inner sides of the diagonal bracing beam 300 and the support beam 201. Both ends of the connecting rod 500 are bolted to the diagonal bracing beam 300 and the support beam 201 respectively through the connecting blocks 501. The connection between the support beam 201 and the diagonal bracing beam 300 is reinforced by the connecting rod 500.

[0030] In addition, all bolts are high-strength bolts, which facilitates the disassembly and assembly of each component.

[0031] Specifically, when supporting the cantilever slab 600, the support beam 201 is connected to the building wall by bolts, such as expansion bolts. The support beam 201 and the diagonal bracing beam 300 are installed at the lower end of the connecting beam 100 through the connecting plate 204 to support the connecting beam 100. The connecting beam 100 is installed below the cantilever slab 600 by bolts to support the cantilever slab 600. The support beam 201 and the connecting beam 100 are formed into a triangular support structure through the connecting rod 202 for support. The diagonal bracing beam 300 is installed on the front side of the support beam 201 through the strengthening component 400, and the triangular structure composed of the support beam 201, the connecting beam 100 and the diagonal bracing beam 300 is used to support the cantilever slab 600;

[0032] Considering that the support structure is in a suspended state and better supporting force is required to stably support the cantilever slab 600, therefore, the bearing capacity is improved by the strengthening component 400 between the bottom of the diagonal bracing beam 300 and the support beam 201. The included angle between the diagonal bracing beam 300 and the cross beam 203 is pre-adjusted according to the structure of the cantilever slab 600 and fixed by bolts. According to the distance between the diagonal bracing beams 300, the directions of the cross rod 401 and the bottom rod 402 outside the fixed rod 404 are adjusted and fixed by bolts. Then the fixed rod 404 is connected to the mounting seat 403 on the support beam 201 to realize the connection between the diagonal bracing beam 300 and the support beam 201. The diagonal bracing rod is supported by the triangular support structure composed of the bottom rod 402, the cross rod 401 and the support beam 201. The structure of the bottom rod 402 and the cross rod 401 is reinforced by the support rod 406 to make its bearing capacity better. The connection between the support beam 201 and the diagonal bracing beam 300 is reinforced by the connecting rod 500, so that the support beam 201, the diagonal bracing beam 300 and the connecting rod 500 form a triangular structure for stable support.

[0033] In addition, due to its geometric properties, the triangular structure is usually used in engineering structures to provide stability and strength. In the support of the cantilever slab 600, in the triangular support structure, the lower end (i.e., the corner point in contact with the main structure) is the place where greater forces are borne. This is because the bottom edge of the reaction force triangle of the support point contacts the main structure, and the support point will bear the reaction force from the weight of the cantilever slab 600 and the upper structure. In the static equilibrium state, this reaction force is equal to the total weight of the cantilever slab 600 and the upper structure. Therefore, it can be considered that in the triangular support structure, the force at the lower end position is relatively large, especially at the support point. Therefore, the strengthening component 400 is provided to strengthen the lower end, thereby improving the bearing capacity of the support structure.

[0034] The connecting beam 100, support frame 200, support beam 201, connecting rod 202, cross beam 203, connecting plate 204, diagonal support beam 300, cross bar 401, bottom bar 402, mounting seat 403, fixed rod 404, fastening block 405, support rod 406, connecting rod 500, connecting block 501, cantilever slab 600 and other components of the present utility model are all common standard parts or parts known to those skilled in the art, and their structures and principles can all be known by those skilled in the art through technical manuals or obtained through conventional experimental methods.
