Description

Technical Field

[0001] This utility model relates to the field of steel formwork support technology, and in particular to a steel formwork support structure for wind turbine pouring. Background Technology

[0002] Wind energy is a clean and pollution-free renewable energy source. Utilizing wind power is very environmentally friendly, and wind energy reserves are enormous, thus attracting increasing attention from countries worldwide. Currently, the foundation structure of wind turbines is ring-shaped, and the turbine tower has a conical structure. The foundation of the wind turbine is made of cast concrete. In the foundation casting technology of wind turbines, it is necessary to prepare the power generation base formwork in advance. Circular concrete columns, as basic supporting units in modern architecture, are widely used in some high-rise or large buildings. To improve the strength of circular concrete columns and strengthen the connection with connected structures, these circular concrete columns are usually cast-in-place using on-site support. Therefore, a steel formwork support structure for wind turbine casting is used.

[0003] In existing technologies, the steel formwork support structure for wind turbine casting often uses diagonal support rods installed behind the steel formwork, with the other end of the rods fixed to the ground to support the formwork. However, when supporting the steel formwork with diagonal rods, only one or two support points are applied to the formwork. As a result, when pouring concrete into the assembled steel formwork, the outward expansion force exerted by the concrete after pouring may cause the support force applied outside the support points to become insufficient, leading to loosening or deformation at the joints of each steel formwork. This affects the quality of concrete forming and, in severe cases, may even cause instability of the assembled steel formwork system. Utility Model Content

[0004] The technical problem to be solved by this utility model is to provide a steel formwork support structure for wind turbine casting to solve the problem that when an outward expansion force is applied to the assembled steel formwork after concrete is poured, the support force applied outside the support points of the steel formwork is insufficient, which leads to the loosening or deformation of the connection of each steel formwork, thereby affecting the quality of concrete molding, and in severe cases may even cause the instability of the assembled steel formwork system.

[0005] To solve the above-mentioned technical problems, this utility model provides the following technical solution:

[0006] A steel formwork support structure for wind turbine casting includes a main body and a support connection part, wherein the support connection part is fixedly connected to the back of the main body, and further includes:

[0007] The support mechanism includes two support connecting plates, both of which are detachably installed on the side of the support connection part away from the main body. Each of the two support connecting plates is rotatably connected to a support arm on the side away from the support connection part, and a connecting sleeve is rotatably connected to the end of each support arm away from the support connecting plate.

[0008] A positioning mechanism, comprising a threaded support column, which is slidably connected inside a connecting sleeve, and a threaded limiting sleeve is threadedly connected to the outer wall of the threaded support column.

[0009] Preferably, the main body has assembly ends on both opposite sides, and the bottom of the main body has a blade-shaped part.

[0010] Preferably, there are two supporting connection parts, which are symmetrically distributed around the main body.

[0011] Preferably, the two support arms are arranged symmetrically about the connecting sleeve.

[0012] Preferably, the supporting round block abuts against the supporting connecting part, the threaded limiting cylinder abuts against the connecting sleeve, and the outer wall of the threaded limiting cylinder is provided with a handle.

[0013] Preferably, a T-shaped support frame is fixedly connected to the side of the threaded support column away from the insertion hole. The T-shaped support frame is inverted T-shaped and has two sets of fixing holes at its bottom.

[0014] Preferably, a positioning support arm is rotatably connected to the side of the T-shaped support frame away from the threaded support column, a positioning block is rotatably connected to the end of the positioning support arm away from the T-shaped support frame, and an extension is fixedly connected to the side of the positioning block away from the T-shaped support frame.

[0015] Preferably, both the positioning block and the top of the extension are provided with a support insertion hole, and a positioning pin is inserted into the support insertion hole at the top of both the positioning block and the extension.

[0016] Preferably, the threaded support column has an insertion hole on the side near the support connection part, an insertion column is inserted into the insertion hole, and a support block is fixedly connected to the side of the insertion column near the support connection part.

[0017] Compared with the prior art, this utility model has at least the following beneficial effects:

[0018] In the above scheme, after the two supporting connecting plates are installed on a single supporting connecting part by fixing bolts, the threaded support column is inserted into the inside of the connecting sleeve. After the insertion end of the threaded support column passes through the connecting sleeve, the supporting block is inserted into the insertion hole through the insertion column. Then, the threaded support column is continuously pushed so that the supporting block abuts against the supporting connecting part at the position between the two supporting connecting plates. Then, the threaded limiting cylinder is rotated so that the threaded limiting cylinder moves to abut against the connecting sleeve. Support points can be set at the upper and lower ends and the middle of the supporting connecting part. When the two supporting connecting plates and the supporting block are subjected to thrust, the force can be concentrated on the threaded support column. The force on the threaded support column is borne by the T-shaped support frame, positioning support arm, positioning block, extension part and positioning pin, thereby improving the support effect on the main body and improving the stability of the assembled main body when pouring concrete. When an outward expansion force is applied to the main body after the concrete is poured, it avoids the phenomenon of loosening or deformation of each connection of the main body due to insufficient support force applied to the main body support points, thereby improving the molding quality of concrete.

[0019] By using the blade-shaped part at the bottom of the main body, water is sprayed at the steel formwork assembly site during the main body assembly to soften the soil. A hammering force is then applied from the top of the steel formwork to cause the main body to be driven into the ground. This allows individual main bodies to be pre-installed in designated positions, facilitating the installation of support and positioning mechanisms on the support connections. At the same time, embedding the bottom area of ​​the main body into the ground improves the tightness of the connection between the bottom of the assembled steel formwork and the ground, reducing the phenomenon of concrete overflowing from the bottom of the steel formwork during pouring, thus improving the concrete forming effect and making it highly practical.

[0030] like Figures 1-5 As shown, an embodiment of this utility model provides a steel formwork support structure for wind turbine casting, including a main body 1 and a support connection part 102. The support connection part 102 is fixedly connected to the back of the main body 1. Assembly ends 101 are provided on both opposite sides of the main body 1, and a blade-shaped part is provided at the bottom of the main body 1. By spraying water at the steel formwork assembly point during the assembly of the main body 1 through the blade-shaped part at the bottom of the main body 1, the soil at the steel formwork assembly point is softened. A hammering force is applied from the top of the steel formwork, which can cause the main body 1 to be inserted into the ground, thereby allowing a single main body 1 to be pre-installed in a designated position. There are two support connection parts 102, which are symmetrically distributed around the main body 1 for assembling multiple main bodies 1.

[0031] Support mechanism 2 includes two support connecting plates 201, both of which are detachably installed on the side of support connection part 102 away from the main body 1. Support arms 202 are rotatably connected to the side of each support connecting plate 201 away from the support connection part 102. Connecting sleeves 203 are rotatably connected to the ends of each support arm 202 away from the support connecting plate 201. The two support arms 202 are symmetrically arranged vertically around the connecting sleeves 203. The two support connecting plates 201 are installed on a single support connection part 1 using fixing bolts. After 02, insert the threaded support column 301 into the inside of the connecting sleeve 203. After the insertion end of the threaded support column 301 passes through the connecting sleeve 203, insert the support block 310 into the insertion hole 308 through the insertion column 309. Then, continue to push the threaded support column 301 so that the support block 310 abuts against the support connection part 102 at the position between the two support connection plates 201. Then, rotate the threaded limiting cylinder 302 so that the threaded limiting cylinder 302 moves to abut against the connecting sleeve 203. Support points can be set at the upper and lower ends and the middle of the support connection part 102.

[0032] The positioning mechanism 3 includes a threaded support column 301, which is slidably connected inside the connecting sleeve 203. A threaded limiting sleeve 302 is threadedly connected to the outer wall of the threaded support column 301. An insertion hole 308 is provided on the side of the threaded support column 301 near the supporting connection part 102, and an insertion column 309 is inserted into the insertion hole 308. A supporting block 310 is fixedly connected to the side of the insertion column 309 near the supporting connection part 102, and the supporting block 310 abuts against the supporting connection part 102. The threaded limiting sleeve 302 abuts against the connecting sleeve 203, and a handle is provided on the outer wall of the threaded limiting sleeve 302. A T-shaped support frame 303 is fixedly connected to the side of the threaded support column 301 away from the insertion hole 308. The T-shaped support frame 303 is inverted T-shaped, and two sets of fixing holes are provided at the bottom of the T-shaped support frame 303. A positioning support arm 304 is rotatably connected to one side of 301. A positioning block 305 is rotatably connected to the end of the positioning support arm 304 away from the T-shaped support frame 303. An extension 306 is fixedly connected to the side of the positioning block 305 away from the T-shaped support frame 303. Support insertion holes are provided through the top of both the positioning block 305 and the extension 306. Positioning pins 307 are inserted into the support insertion holes at the top of both the positioning block 305 and the extension 306. When the two support connecting plates 201 and the support round block 310 are subjected to a pushing force, the force can be concentrated on the threaded support column 301. The force on the threaded support column 301 is borne by the T-shaped support frame 303, the positioning support arm 304, the positioning block 305, the extension 306 and the positioning pin 307, thereby improving the support effect on the main body 1 and improving the stability of the assembled main body 1 when pouring concrete.

[0033] After the two support connecting plates 201 and the support round block 310 abut against the support connecting part 102, the position of the support mechanism 2 is fixed by inserting a ground pin into the bottom of the T-shaped support frame 303 to fix it to the ground. At the same time, the positioning block 305 and the positioning ground pin 307 on the extension part 306 are fixed to the ground by the positioning block 305 and the positioning ground pin 307. The T-shaped support frame 303 is fully supported by the positioning support arm 304.

[0034] Working principle: After the two support connecting plates 201 are installed on the single support connecting part 102 by fixing bolts, the threaded support column 301 is inserted into the inside of the connecting sleeve 203. After the insertion end of the threaded support column 301 passes through the connecting sleeve 203, the support block 310 is inserted into the insertion hole 308 through the insertion post 309. Then, the threaded support column 301 is continuously pushed so that the support block 310 abuts against the support connecting part 102 at the position between the two support connecting plates 201. Then, the threaded limit is rotated. The cylinder 302 moves the threaded limiting cylinder 302 to abut against the connecting sleeve 203. Support points can be set at the upper and lower ends and the middle of the support connection part 102. When the two support connecting plates 201 and the support block 310 are subjected to thrust, the force can be concentrated on the threaded support column 301. The force on the threaded support column 301 is borne by the T-shaped support frame 303, the positioning support arm 304, the positioning block 305, the extension part 306 and the positioning ground pin 307, thereby improving the support effect on the main body 1.

[0035] By using the blade-shaped part at the bottom of the main body 1, water is sprayed at the steel formwork assembly site during the assembly of the main body 1 to soften the soil at the steel formwork assembly site. The hammering force applied from the top of the steel formwork can cause the main body 1 to be driven into the ground, thereby allowing the individual main body 1 to be pre-installed in the designated position. This facilitates the installation of the support mechanism 2 and the positioning mechanism 3 on the support connection part 102. At the same time, by embedding the bottom area of ​​the main body 1 into the ground, the tightness of the connection between the bottom of the assembled steel formwork and the ground can be improved.
