Description

Technical Field

[0001] This utility model relates to the field of support device technology, specifically an adjustable steel pipe concrete support device for a combined structure. Background Technology

[0002] Adjustable steel-concrete composite supports are a common support structure in modern construction, widely used in high-rise buildings, bridges, tunnels, and other engineering projects. They are primarily used to support and stabilize structures, ensuring safety and stability during construction. In high-rise building construction, due to the complexity of the structure and the special requirements of high-altitude operations, this support device can provide effective temporary support, ensuring construction safety. It typically uses steel pipes with circular, square, or rectangular cross-sections, serving as the outer shell of the structure, with concrete filling the interior. Ordinary or high-performance concrete is generally used. Under the constraint of the steel pipe, the compressive strength and ductility of the concrete are significantly improved.

[0003] However, when using existing equipment for steel pipe concrete construction, the steel pipe is usually placed horizontally on the support plate of the support device before concrete is injected into it. However, traditional support devices have obvious drawbacks. The support plate is fixed, and as concrete is injected into the steel pipe by pumping or other means, the weight of the steel pipe itself and the impact force generated by the flow of concrete inside combine to cause the steel pipe to sway on the support plate of the support device. This may result in uneven concrete distribution and may also pose safety hazards, such as the steel pipe slipping and injuring people. Utility Model Content

[0004] The purpose of this invention is to provide an adjustable steel-concrete composite support device for combined structures to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an adjustable steel-concrete composite support device for a combined structure, comprising a base, a support column, a guide rail groove, a steel-concrete composite body, and a clamping support assembly. The clamping support assembly includes a square adjusting block, one end of which is fixedly connected to a support plate. A sliding groove is provided inside the support plate, and a moving block is slidably connected inside the sliding groove. A first clamping plate and a second clamping plate are fixedly connected to the upper end of the moving block. A forward-threaded cylinder is fixedly connected to the lower end of the first clamping plate, and a reverse-threaded cylinder is fixedly connected to the lower end of the second clamping plate.

[0006] As a further preferred embodiment of this technical solution, a forward screw is rotatably connected inside the forward threaded cylinder, a reverse screw is fixedly connected to one end of the forward screw, and a reverse threaded cylinder is rotatably connected to the outside of the reverse screw.

[0007] As a further preferred embodiment of this technical solution, one end of the reverse threaded cylinder is rotatably connected to the inside of the bearing, one end of the bearing is fixedly installed on one end of the square adjusting block, and one end of the forward lead screw is fixedly connected to a rotating wheel.

[0008] As a further preferred embodiment of this technical solution, a sliding block is fixedly connected inside the square adjusting block, and the sliding block is slidably connected inside the guide rail groove, which is located inside the support column.

[0009] As a further preferred embodiment of this technical solution, the support column has a through hole inside, and a pin is connected through the through hole, with a handle provided at one end of the pin.

[0010] As a further preferred embodiment of this technical solution, a fixed cylinder is fixedly installed inside the base, and a threaded rod is rotatably connected inside the fixed cylinder, with a handle fixedly installed at the upper end of the threaded rod.

[0011] This utility model provides an adjustable steel-tube concrete support device for composite structures, which has the following advantages:

[0012] (1) This utility model clamps and fixes the steel pipe concrete by means of a clamping support assembly, a first clamping plate and a second clamping plate. The concrete is injected into the steel pipe to prevent the steel pipe from shaking on the support plate of the support device due to the impact force generated by the weight of the steel pipe itself and the flow of the internal concrete.

[0020] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0021] This utility model provides a technical solution: such as Figures 1 to 5 As shown, an adjustable steel-concrete composite support device for a combined structure includes a base 1, a support column 11, a guide rail groove 15, a steel-concrete composite body 2, and a clamping support assembly 3. The clamping support assembly 3 includes a square adjusting block 394, one end of which is fixedly connected to a support plate 32. A sliding groove 36 is formed inside the support plate 32, and a moving block 391 is slidably connected inside the sliding groove 36. A first clamping plate 33 and a second clamping plate 34 are fixedly connected to the upper end of the moving block 391. The lower end of the 3 is fixedly connected to a forward threaded cylinder 392, and the lower end of the second clamping plate 34 is fixedly connected to a reverse threaded cylinder 393. The inside of the forward threaded cylinder 392 is rotatably connected to a forward lead screw 39, one end of the forward lead screw 39 is fixedly connected to a reverse lead screw 38, the outside of the reverse lead screw 38 is rotatably connected to a reverse threaded cylinder 393, one end of the reverse threaded cylinder 393 is rotatably connected to the inside of a bearing 37, one end of the bearing 37 is fixedly installed on one end of a square adjusting block 394, and one end of the forward lead screw 39 is fixedly connected to a rotating wheel 35.

[0022] In this design, after the steel-concrete composite body 2 is placed above the support plate 32, the operator manually rotates the rotating wheel 35. The rotation of the wheel 35 drives the forward lead screw 39 and the reverse lead screw 38 to rotate synchronously. The reverse lead screw 38 rotates within the bearing 37, the forward lead screw 39 rotates within the forward threaded cylinder 392, and the reverse lead screw 38 rotates within the reverse threaded cylinder 393. This causes relative movement between the forward and reverse threaded cylinders 392 and 393, which in turn drives the first clamping plate 33 and the second clamping plate 34 to move in opposite directions. Simultaneously, it also causes the moving block 391 to move within the sliding groove 36 of the support plate 32. Through the process of the first clamping plate 33 and the second clamping plate 34 moving in opposite directions and clamping, the clamping support assembly 3 can adapt to steel pipes of different sizes and clamp and fix them.

[0023] In this embodiment, the steel pipe concrete is clamped and fixed by the clamping support assembly 3, the first clamping plate 33 and the second clamping plate 34. The concrete is injected into the steel pipe to prevent the steel pipe from shaking on the support plate 32 of the support device due to the impact force generated by the weight of the steel pipe and the flow of the internal concrete. This prevents uneven distribution of concrete and avoids safety hazards such as the steel pipe slipping and injuring people. The clamping support assembly 3 can adapt to steel pipes of different sizes and clamp and fix them.

[0024] like Figures 2 to 4 As shown, a sliding block 31 is fixedly connected inside the square adjusting block 394. The sliding block 31 is slidably connected inside the guide rail groove 15. The guide rail groove 15 is opened inside the support column 11. A through hole 16 is opened inside the support column 11. A pin 18 is connected through the through hole 16. A handle 17 is provided at one end of the pin 18. A fixed cylinder 12 is fixedly installed inside the base 1. A threaded rod 13 is rotatably connected inside the fixed cylinder 12. A handle 14 is fixedly installed at the upper end of the threaded rod 13.

[0025] In this scheme, the operator first holds the square adjusting block 394 or the component connected to the square adjusting block 394 and applies upward or downward movement to it. The sliding block 31 slides in the guide rail groove 15 along the direction of the guide rail groove 15. When the square adjusting block 394 moves to a suitable height position, the operator needs to insert the pin 18 into the through hole 16 inside the support column 11 to fix the position of the square adjusting block 394. The operator can easily operate the insertion and removal of the pin 18 through the handle 17. The fixed cylinder 12 inside the base 1 and the threaded rod 13 form a screw transmission pair. By rotating the threaded rod 13, the threaded rod 13 is moved axially relative to the fixed cylinder 12 by the transmission action of the thread, thereby realizing the fine adjustment of the overall height of the base 1 to ensure the levelness and stability of the support device.

[0026] In this implementation, the height of the support plate 32 of the support device can be adjusted by moving the square adjustment block 394 up or down according to the different heights of the steel pipe concrete body 2, and it can be applied to various construction scenarios with different height requirements.

[0027] This utility model provides an adjustable steel pipe concrete support device for a combined structure. The specific working principle is as follows: When the steel pipe concrete body 2 is placed above the support plate 32, the operator manually rotates the rotating wheel 35. The rotation of the rotating wheel 35 will drive the forward lead screw 39 and the reverse lead screw 38 to rotate synchronously. The reverse lead screw 38 rotates within the bearing 37, the forward lead screw 39 rotates within the forward threaded cylinder 392, and the reverse lead screw 38 rotates within the reverse threaded cylinder 393. This causes the forward threaded cylinder 392 and the reverse threaded cylinder 393 to move relative to each other, thereby driving the first clamping plate 33 and the second clamping plate 34 to move in opposite directions. At the same time, it also drives the moving block 391 to move within the sliding groove 36 of the support plate 32. Through the process of the first clamping plate 33 and the second clamping plate 34 moving in opposite directions and clamping, the clamping support assembly 3 can adapt to steel pipes of different sizes and clamp and fix them. The operator first holds the square adjusting block 394 or the part connected to the square adjusting block 394 and applies upward or downward movement to it. The sliding block 31 slides in the guide rail groove 15 along the direction of the guide rail groove 15. When the square adjusting block 394 moves to the appropriate height position, the operator needs to insert the pin 18 into the through hole 16 inside the support column 11 to fix the position of the square adjusting block 394. The operator can conveniently operate the insertion and removal of the pin 18 through the handle 17.

[0028] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
