Description

Technical Field

[0001] The present application relates to the technical field of high-altitude cantilever structures, and in particular to a high-altitude cantilever structure erection platform. Background Art

[0002] With the diversification of modern architectural design functions, in order to meet the visual effect of the facade floating in the air and meet the requirements of large indoor areas, cantilever structure has become one of the important technical means to achieve unique architectural design.

[0003] In the construction of cantilever beams, support platforms are usually used for support. Some existing support platforms are ground-type formwork support systems. This support method has the problems of high cost and large space occupation. Therefore, some people choose to use steel cantilever scaffolding, which adopts I-beam cantilever, uses steel wire ropes and steel tie rods for upward inclined tensioning, and steel for downward inclined support. This cantilever support method has strict requirements on the length of the I-beam, and requires a large number of embedded parts such as steel wire ropes and steel tie rods. In addition, the positioning of embedded parts needs to be strictly controlled to prevent displacement during concrete pouring. The time spent and the accuracy are high, which affects the subsequent construction efficiency, so further improvement is needed. Utility Model Content

[0004] In order to reduce the impact on the overall construction work efficiency, the present application provides a high-altitude cantilever structure erection platform.

[0005] The application provides a high-altitude cantilever structure erection platform, which adopts the following technical solutions:

[0006] A high-altitude cantilever structure erection platform includes a support rod connected to the side wall of a building, a formwork frame arranged above the support rod, an inclined rod arranged below the support rod, and a support rod arranged on the inclined rod, wherein the length direction of the support rod is parallel to the upper surface of the building, the upper end of the inclined rod is fixedly connected to the end of the support rod away from the floor slab, the lower end of the inclined rod is fixedly connected to the side wall of the building, one end of the support rod is fixedly connected to the middle part of the support rod, and the other end of the support rod is fixedly connected to the support rod.

[0007] By adopting the above technical solution, a triangular support is formed between the support rod, the diagonal rod and the building. Due to the high stability of the triangle, it provides support for the formwork frame set on the support rod and the subsequent cantilever structure. Compared with the ground-type cantilever support, the overall erection height is smaller and the cost is also reduced. Compared with the cantilever beam structure supported by the steel wire rope diagonal brace, the required embedded parts are also reduced, and the impact on the overall construction efficiency is also lower.

[0008] Preferably, the support rod comprises a first support rod connected to one end of the support rod close to the building and a second support rod fixedly connected to the middle part of the support rod.

[0009] By adopting the above technical solution, the support rods include the first support rod and the second support rod, and form multiple triangles between the support rod and the diagonal rod, so as to increase the connection between the support rod and the diagonal rod, and also increase the support for the upper vertical rod and the cantilever structure.

[0010] Preferably, support members are provided on both sides of the middle portion of the oblique rod.

[0011] By adopting the above technical solution, when the support rod connected to the middle part of the diagonal support is subjected to the gravity of the upper formwork frame, the pressure on the middle part of the support rod increases. At this time, a support member is provided to provide a certain supporting load strength for the diagonal rod.

[0012] Preferably, the support member includes support plates fixedly connected to both sides of the oblique rod.

[0013] By adopting the above technical solution, support is provided for the wing plate in the diagonal rod.

[0014] Preferably, the support member is a supporting I-beam, the diagonal rod is an I-beam, the two wing plates of the supporting I-beam are respectively fixed to the surfaces of the two wing plates in the diagonal rod that are close to each other, and the web of the supporting I-beam is vertically fixed to the web in the diagonal rod.

[0015] By adopting the above technical solution, the support members and the diagonal rods are I-beams, which reduces the time required for precise positioning during fixation, is more convenient, and the bearing capacity of the diagonal rods is also improved.

[0016] Preferably, the formwork frame includes a vertical pole fixedly connected to the support rod, the length direction of the vertical pole is perpendicular to the length direction of the support rod, a plurality of vertical poles are arranged at intervals along the length direction of the support rod, and shear braces are fixedly connected between the vertical poles near both ends of the support rod.

[0017] By adopting the above technical solution, the shear brace is provided to improve the connection between the vertical poles at both ends of the support rod, thereby improving the connection effect of the vertical poles far away from the building.

[0018] Preferably, the formwork frame also includes a cross bar fixedly connected to the vertical pole, the length direction of the cross bar is parallel to the length direction of the support pole, a plurality of cross bars are arranged at intervals along the height direction of the vertical pole, and the ends of the shear braces are fixedly connected to the cross bar.

[0019] By adopting the above technical solution, the connection strength between adjacent vertical poles is improved by setting the cross bar, and the shear brace is also convenient for fixing, so as to reduce the difficulty of installing the shear brace on the vertical pole.

[0020] Preferably, the spacing between adjacent uprights gradually decreases in a direction away from the building.

[0021] By adopting the above technical solution, the supporting effect of the support rod on the vertical pole is gradually reduced when it is arranged in the direction away from the building. Therefore, by gradually reducing the distance between adjacent vertical poles in the direction away from the building, the connection effect between the vertical poles away from the building and the building is improved, thereby improving the supporting effect of the subsequent cantilever structure.

[0022] Preferably, the formwork support frame further comprises a guy brace, the lower end of which is fixedly connected to the upper surface of the floor slab, and the upper end of which is inclined toward the direction close to the vertical pole and fixedly connected to the vertical pole.

[0023] By adopting the above technical solution and setting a guy brace, the connection strength between the opposing poles and the building can be further improved.

[0024] In summary, the utility model has the following beneficial effects:

[0025] 1. A triangular support is formed between the support rod, the diagonal rod and the building. Due to the high stability of the triangle, it provides support for the formwork frame set on the support rod and the subsequent cantilever structure. Compared with the ground-type cantilever support, the overall erection height is smaller and the cost is also reduced. Compared with the cantilever beam structure supported by the steel wire rope diagonal brace, the required embedded parts are also reduced, and the impact on the overall construction efficiency is also lower.

[0026] 2. By providing support members, a certain supporting load strength is provided to the diagonal rod. BRIEF DESCRIPTION OF THE DRAWINGS
