Description

Technical Field

[0001] This utility model relates to a support device, and more particularly to a support device for the construction of internal formwork for a wind turbine, belonging to the field of building construction technology. Background Technology

[0002] In wind turbine foundation construction, the internal formwork support system is crucial for ensuring the shape and strength of the concrete pour. Existing internal formwork supports have the following drawbacks in practical applications: ① Traditional supports mostly use wood or special metal materials. Wood has low strength and is easily deformed, while metal materials are expensive and complex to process, leading to an increase in overall construction costs; ② Existing supports have simple structural designs and limited load-bearing capacity. Especially in the construction of circular extended wind turbine foundations, they are difficult to meet the high load-bearing requirements, which can easily lead to formwork deformation and affect construction quality; ③ The installation and removal process of traditional supports is complicated, requiring multiple adjustments and fixations, resulting in low construction efficiency. Furthermore, removing the supports after pouring may damage the foundation structure. Utility Model Content

[0003] The technical problem to be solved by this utility model is to overcome the shortcomings of the prior art and provide a support device for the construction of the inner formwork of a wind turbine, which can effectively support the inner formwork and scaffolding, ensure the stability of construction, and improve the construction quality.

[0004] The technical solution adopted by this utility model to solve the technical problem is as follows: A support device for the construction of internal formwork for a wind turbine includes a steel bar body, a ring plate in the middle of the steel bar body, and steel bar ends on both sides of the upper part of the steel bar body.

[0005] A circular through hole is cut in the middle of the ring, and the inner diameter of the circular through hole matches the outer diameter of the main body of the reinforcing bar. The ring is fitted onto the main body of the reinforcing bar and welded together with the main body of the reinforcing bar.

[0006] The length of the main body of the steel bar is 350mm, and the length of the end of the steel bar is 50mm.

[0007] The distance between the top of the rebar head and the top of the rebar body is 100mm.

[0008] The outer diameter of the ring is larger than the cross-section of a single steel mesh.

[0009] The diameter of the main steel bar is smaller than the diameter of a single steel pipe in the scaffold, and the distance between two steel bar ends is greater than the diameter of a single steel pipe in the scaffold.

[0010] The positive and beneficial effects of this utility model are: 1. This utility model forms a stable support structure by setting a ring plate in the middle of the reinforcing bar and setting reinforcing bar ends on both sides of the upper part of the reinforcing bar; the ring plate is firmly welded to the reinforcing bar, which enhances the overall load-bearing capacity and can effectively support the weight of the inner formwork and scaffolding, ensuring the stability and safety of the formwork during construction, thereby improving the construction quality of the wind turbine foundation.

[0011] 2. This utility model uses common steel bars as the main material, which are easy to obtain on the construction site. No special customized materials are required, which reduces construction costs. The structure is simple and easy to manufacture. Attached Figure Description

[0012] Figure 1 This is a schematic diagram of the structure of this utility model; Figure 2 This is a site construction drawing for this utility model; Among them: 1-reinforcing bar body, 2-ring plate, 3-reinforcing bar head, 4-reinforcing bar mesh, 5-single steel pipe. Detailed Implementation

[0013] The present invention will be further explained and described below with reference to the accompanying drawings: See the example. Figures 1-2 A support device for the construction of internal formwork for a wind turbine includes a steel bar body 1, a ring plate 2 is provided in the middle of the steel bar body 1, and steel bar ends 3 are provided on both sides of the upper part of the steel bar body 1.

[0014] A circular through hole is drilled in the middle of the ring 2. The inner diameter of the circular through hole matches the outer diameter of the steel body 1. The ring 2 is fitted onto the steel body 1 and welded together with the steel body 1.

[0015] The length of the main steel bar 1 is 350mm, and the length of the steel bar end 3 is 50mm.

[0016] The distance between the top of the rebar head 3 and the top of the rebar body 1 is 100mm.

[0017] The outer diameter of the ring 2 is larger than the cross-section of a single steel mesh 4.

[0018] The diameter of the main steel bar 1 is smaller than the diameter of a single steel pipe 5 in the scaffold, and the distance between two steel bar ends 3 is greater than the diameter of a single steel pipe 5 in the scaffold.

[0019] In the above description, the diameter of the ring is 120mm and the thickness is 4mm. The ring is perpendicular to the main body of the reinforcing bar and is welded tightly together.

[0020] In the above description, the two rebar ends are arranged side by side with the main rebar body and are tightly welded together.

[0021] In the above description, the diameter of the ring is larger than the size of a single mesh of the reinforcing mesh, allowing the ring to be placed on the reinforcing mesh.

[0022] In the above description, there are two steel bar ends, which are welded to both sides of the main steel bar body and distributed side by side with the main steel bar body, and the steel bar ends are located above the ring plate.

[0023] When in use, place the ring plate on the middle layer of steel mesh, and then fix the main body of the steel bar above the ring plate to the upper layer of steel mesh with steel wire; the steel pipe in the scaffolding is put on top of the main body of the steel bar and placed on the upper part of the two steel bar ends. At this time, the steel bar ends play the role of supporting the scaffolding. During pouring, the device can be embedded in the foundation; after the formwork is removed, the main body of the steel bar that exceeds the foundation can be cut.

[0024] This utility model forms a stable support structure by setting a ring plate in the middle of the reinforcing bar and setting reinforcing bar ends on both sides of the upper part of the reinforcing bar, which enhances the overall load-bearing capacity and can effectively support the weight of the inner formwork and scaffolding, ensuring the stability and safety of the formwork during construction, thereby improving the construction quality of the wind turbine foundation.
