AI Technical Summary
In traditional wind turbine hybrid tower foundation construction, the formwork support steel pipes for the cantilevered section cannot be recycled, increasing the workload and cost of dismantling, and the waterproofing effect is poor.
The formwork supports are made of reinforcing steel bars and steel plates, with the reinforcing steel bars exposed on the concrete surface. The supporting steel pipes are connected to the reinforcing steel bars to prevent the steel pipes from being buried in the concrete. Combined with adjustable supports, stable support is achieved, and the water penetration path is extended by steel plates to enhance the waterproofing effect.
This enables the recycling and reuse of steel pipes, reduces construction costs, simplifies formwork removal, and improves waterproofing performance and construction efficiency.

Description
TECHNICAL FIELD
[0001] The utility model relates to the field of wind power mixed tower foundation construction, and particularly relates to a formwork support foot for a wind power mixed tower foundation cavity overhang part. BACKGROUND
[0002] In the construction of a wind power mixed tower foundation, a formwork structure for supporting the overhang part is often needed. The conventional support method usually adopts a steel pipe for support. After the concrete below the overhang part is poured, a part of the formwork support steel pipe will be embedded in the concrete. In the subsequent form removal process, the support steel pipe needs to be sawn off, which increases the removal workload and time. Meanwhile, a large number of steel pipes cannot be recycled, which increases the cost. SUMMARY
[0003] The utility model aims at solving the prior art's insufficient, and provides a formwork support foot for a wind power mixed tower foundation cavity overhang part.
[0004] To achieve the above-mentioned purpose, the utility model adopts the following technical scheme.
[0005] A formwork support foot for a wind power mixed tower foundation cavity overhang part, comprising a support steel bar I, a bottom steel plate, a support steel pipe and an adjustable support, the bottom steel plate is arranged in the concrete below the wind power mixed tower foundation cavity overhang part, a steel bar welded with the bottom steel plate is vertically welded below the support steel bar I, the bottom of the steel bar is welded with the bottom steel plate, four support steel bars II are welded around the upper part of the support steel bar I, the support steel pipe is sleeved on the top of the support steel bar I, and the support steel bar II is in contact with the pipe wall of the support steel pipe.
[0006] The length of the support steel bar I is greater than the thickness of the concrete below the overhang part by 100 mm, that is, the support steel bar I is exposed from the concrete below the overhang part by 100 mm.
[0007] The top surface of the support steel bar II is flush with the concrete surface below the overhang part.
[0008] The length of the steel bar welded with the bottom steel plate is 100 mm.
[0009] The size of the bottom steel plate is 150 mm*150 mm*3 mm.
[0010] The beneficial effects of this utility model are as follows: the supporting steel pipe of this utility model can be recycled and reused, avoiding the situation where steel pipes cannot be recycled in traditional formwork methods, thereby reducing steel pipe waste and lowering construction costs. Waste materials from the processing of foundation steel bars can be used as raw materials for formwork support feet, making reasonable use of waste materials. The design of the bottom steel plate extends the seepage path compared to steel pipe support, effectively preventing concrete seepage and enhancing the waterproof effect of the structure. When dismantling the formwork, only the supporting steel pipe needs to be removed, without sawing or damaging the steel pipe, thereby simplifying the dismantling work and improving construction efficiency.

Detailed Implementation
[0015] The present invention will be further described below with reference to the accompanying drawings and embodiments:
[0016] A formwork support for the cantilevered portion of a wind turbine hybrid tower foundation cavity includes a supporting steel bar I1, a bottom steel plate 2, a supporting steel pipe 5, and an adjustable support 6. The bottom steel plate 2 is set in the concrete below the cantilevered portion of the wind turbine hybrid tower foundation cavity. A steel bar 3 is vertically welded to the bottom of the supporting steel bar I1 and welded to the bottom steel plate. The bottom of the steel bar 3 welded to the bottom steel plate 2 is welded to the bottom steel plate 2. Four supporting steel bars II4 are welded around the upper part of the supporting steel bar I1. The supporting steel pipe 5 is sleeved on the top of the supporting steel bar I1, and the supporting steel bars II4 are in contact with the pipe wall of the supporting steel pipe 5 to form a force transmission path.
[0017] The length of the supporting steel bar I1 is 100mm greater than the thickness of the concrete below the cantilever, that is, the supporting steel bar I1 protrudes 100mm from the concrete below the cantilever to facilitate the installation and use of the supporting steel pipe 5 and ensure the safety of the support.
[0018] The top surface of the supporting steel bars II4 is flush with the concrete surface below the cantilever section. These supporting steel bars II4 transfer the load to the supporting steel bars I1 through contact with the pipe wall of the upper supporting steel pipe 5, forming an effective force transmission path.
[0019] The length of the steel bar 3 welded with the bottom steel plate is 100mm.
[0020] The size of the bottom steel plate 2 is 150mm*150mm*3mm, the bottom steel plate 2 is used for reinforcing support force, increasing force area, reducing pressure and improving waterproof effect, because the bottom steel plate prolongs water permeation path, thereby improving waterproof performance and preventing water from directly permeating into the foundation cavity.
[0021] In the application, after the foundation steel bar binding is completed, the formwork installation is carried out before pouring concrete, the formwork support foot made is placed on the cushion layer before the formwork installation of the overhanging part, the distance from the cushion layer to the top surface of the support steel bar II 4 is measured, and it is ensured that the thickness of the concrete below the overhanging part is consistent.
[0022] Then, the support steel pipe 5 is sleeved on the top of the formwork support foot, the pipe wall of the support steel pipe 5 is in contact with the support steel bar II 4, a force transmission path is formed, and the upper pressure can be stably transmitted. The adjustable support 6 and the formwork are installed on the top of the support steel pipe 5 in sequence, the angle and height of the formwork are adjusted through the adjustable support 6, and the design requirements are met.
[0023] Then, the concrete pouring is carried out, after the concrete reaches the form removal strength, the adjustable support 6 is adjusted, the formwork is removed, the adjustable support 6 is taken down, finally, the support steel pipe 5 is taken down, because the support steel pipe 5 is not buried in the concrete, but is connected with the formwork support foot through the support steel bar II 4, therefore, the form removal work is not affected, and the support steel pipe 5 can be recycled and reused, so that the waste of the steel pipe in the traditional method is avoided.
[0024] The formwork support foot of the application not only improves the stability of the formwork support through the reasonable design of the steel bar and the steel plate structure, but also prolongs the water permeation path, increases the waterproof effect, further improves the construction speed of the wind power foundation and saves the cost.
