Description

Technical Field

[0001] This utility model belongs to the field of steel arch rib hoisting technology, specifically relating to a temporary support device for steel arch rib hoisting. Background Technology

[0002] Tied arch bridges are mostly used to cross rivers, lakes or other bodies of water. The support system used in the construction of the arch ribs of tied arch bridges must meet the requirements of self-weight, construction load, wind load, and water flow impact. Therefore, the safety of the support system is very important. Moreover, since the arch ribs need to be supported at various angles, the traditional method of using sandboxes and directly welded steel columns as supports is complicated to operate and takes a long time to install and dismantle, making it difficult to meet the support requirements of arch ribs with varying angles. Summary of the Invention

[0003] The purpose of this utility model is to provide a technical solution for a temporary support device for hoisting steel arch ribs, addressing the shortcomings of existing technologies. The device features a clever and reasonable structural design with strong practicality. It employs a support body 1 and a support body 2 to jointly form the support body, effectively enhancing the overall structural strength and stability of the support device and ensuring stable support for the steel arch ribs. Furthermore, the support body is assembled from several support frame units, which can be adjusted according to the height of the steel arch ribs to ensure effective support and prevent any gaps. Simultaneously, a reinforcing component connects the support body 1 and support body 2, enhancing the overall rigidity of the support device and enabling it to better resist external deformation and displacement, thereby improving the safety and reliability of the structure.

[0004] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0005] A temporary support device for hoisting steel arch ribs includes a support base, a support body, and reinforcing components. The support body comprises a first support body and a second support body, which are vertically arranged side-by-side on the support base. A reinforcing component connects the first and second support bodies. Both the first and second support bodies are vertically assembled from support frame units. The structure is ingeniously and rationally designed, highly practical, and the use of the first and second support bodies together to form the support body effectively enhances the overall structural strength and stability of the support device, ensuring stable support for the steel arch rib. Furthermore, the support body, assembled from several support frame units, can be adjusted according to the height of the steel arch rib, ensuring effective support and preventing any gaps. The reinforcing component connects the first and second support bodies, enhancing the overall rigidity of the support device, allowing it to better resist external deformation and displacement, and improving the structural safety and reliability.

[0006] Furthermore, the support base is a concrete base, which is formed by concrete pouring to ensure structural strength and load-bearing capacity, making the structure stable and reliable and ensuring the overall stability of the support device.

[0007] Furthermore, the support frame unit includes four columns, which are connected and fixed together by connecting rods. Flange blind plates are welded and fixed to the top and bottom of the four columns, and the flange blind plates are provided with positioning holes. The structural design is stable and reasonable. The four columns are connected and fixed together by several connecting rods to form a stable quadrilateral structure, ensuring the overall stability and load-bearing capacity of the support frame unit. The design of the flange blind plates facilitates the installation and disassembly of the support frame units. They are connected and fixed by connecting parts through positioning holes. The support frame unit adopts a standardized design, which can facilitate mass production and assembly.

[0008] Furthermore, adjacent support frame units are fixedly connected by bolt assemblies. The bolt assemblies match the positioning holes and connect to the corresponding two flange blind plates through the positioning holes, thus connecting and fixing the adjacent support frame units. The structural design is ingenious and reasonable. The corresponding flange blind plates on the upper and lower adjacent support frame units fit together, and the bolt assemblies cooperate with the positioning holes to ensure the precise positioning and connection of the adjacent support frame units, ensuring connection strength and firmness. The connection method is simple and easy to operate, improving construction efficiency, and is convenient for subsequent replacement or adjustment.

[0009] Furthermore, positioning steel bars are pre-embedded in the support base. The bottom end of the support frame unit at the bottom of the support body is fixed to the support base. The positioning holes on the flange blind plate at the bottom of the bottom support frame unit correspond one-to-one with the positioning steel bars. The part of the positioning steel bar exposed on the support base is inserted into the corresponding positioning hole for limitation. Then, the positioning steel bar is welded and fixed to the flange blind plate. The pre-embedded positioning steel bars correspond one-to-one with the positioning holes on the flange blind plates at the bottom of the two support frame units at the bottom of the two support bodies. The positioning steel bars are inserted and limited in the positioning holes, realizing the precise positioning of support body one and support body two on the support base, which facilitates actual installation and positioning. Then, the positioning steel bars are further welded and fixed to the flange blind plate to form a reliable mechanical connection, effectively improving the connection stability, ensuring the structural safety of the entire support device, and reducing safety hazards.

[0010] Furthermore, the reinforcement component includes two snap-fit ​​frames, which are respectively snapped onto two adjacent columns on support body one and support body two. Each snap-fit ​​frame has a positioning block, and an adjusting screw is connected through the two snap-fit ​​frames, passing through the positioning block. Both ends of the adjusting screw are equipped with fastening nuts. Support body one and support body two are arranged side-by-side on the support base and are precisely positioned and fixed on the support base by positioning steel bars. The reinforcement component is then installed between the two support bodies to further reinforce the connection between them, enhancing the stability of the entire structure. The two snap-fit ​​frames are correspondingly snapped onto the two adjacent columns on the two support bodies, and are also connected through the adjusting screw. By tightening the fastening nuts, the connection between the reinforcement component and the support body is secured and robust. The design is ingenious and reasonable, and assembly and disassembly are convenient and easy, facilitating practical operation.

[0011] Furthermore, the clamping frame includes an adjusting frame and two side clamps. The two side clamps are adjustablely mounted on the adjusting frame, and an adjusting screw is connected through the two side clamps. Both ends of the adjusting screw are equipped with fastening nuts. A clamping groove is formed between the two side clamps, which achieves the clamping and limiting of the clamping frame and the column. The clamping groove between the two side clamps further ensures the clamping frame and the column are securely and stably connected by the adjusting screw and the fastening nuts. This design allows the spacing between the two side clamps to be adjusted, making the clamping frame suitable for clamping and fixing columns of different sizes and shapes, thus expanding its application range.

[0012] Furthermore, the adjustment frame is equipped with a T-shaped groove, and the side clamps are equipped with T-shaped sliders. The T-shaped sliders slide and engage within the T-shaped grooves, matching the T-shaped sliders to achieve a snap-fit ​​installation between the side clamps and the adjustment frame. The T-shaped design ensures tightness and reliability of the snap-fit, guaranteeing the structural stability of the clamping frame. This design also facilitates the adjustment of the distance between the two side clamps. When the two side clamps move and adjust, the side clamps are always limited within the T-shaped grooves by the T-shaped sliders, ensuring the smoothness and reliability of the movement of the side clamps during the adjustment process.

[0013] Furthermore, two sets of T-shaped grooves and T-shaped sliders are provided. The design of two sets of T-shaped grooves and T-shaped sliders can achieve double snap-fit ​​support, enhance the stability and reliability of the connection between the side clamp and the adjustment frame, and also facilitate the subsequent precise and stable adjustment of the side clamp.

[0014] This utility model, by adopting the above-mentioned technical solution, has the following beneficial effects:

[0015] This utility model features a clever and reasonable design with strong practicality. It employs two support bodies to form the main support body, effectively enhancing the overall structural strength and stability of the support device and ensuring its stable support for the steel arch ribs. Furthermore, the main support body is assembled from several support frame units, which can be adjusted according to the height of the steel arch ribs to ensure effective support and prevent any gaps. Additionally, a reinforcing component is connected between the main support body and the main support body, enhancing the overall rigidity of the support device and enabling it to better resist external deformation and displacement, thereby improving the safety and reliability of the structure.

The structural design is ingenious and reasonable. The corresponding flange blind plates 7 on the two adjacent support frame units 11 fit together with the flange blind plates 7. Then, the bolt assembly 9 cooperates with the positioning holes 8 to ensure the precise positioning and connection of the two adjacent support frame units 11, ensuring the connection strength and firmness.

The positioning steel bars 10 are inserted and limited in the positioning holes 8, realizing the precise positioning of support body 1 2 and support body 2 3 on the support base 1, which facilitates the actual installation positioning. Then, the positioning steel bars 10 and flange blind plates 7 are further welded and fixed to form a reliable mechanical connection, which effectively improves the connection stability, ensures the structural safety of the entire support device, and reduces safety hazards.

[0027] The reinforcing component 4 includes two snap-fit ​​frames 12, which are respectively snapped onto two adjacent columns 5 on the first support body 2 and the second support body 3. Each snap-fit ​​frame 12 has a positioning block 13. An adjusting screw 14 is connected between the two snap-fit ​​frames 12, passing through the positioning block 13. Both ends of the adjusting screw 14 are equipped with fastening nuts 15. The first support body 2 and the second support body 3 are arranged side-by-side on the support base 1 and are precisely positioned and fixed on the support base 1 by positioning steel bars 10. The reinforcing component 4 is then installed between the two support bodies, further reinforcing the connection between them and enhancing the stability of the entire structure. The two snap-fit ​​frames 12 are correspondingly snapped onto two adjacent columns 5 on the two support bodies, and are also connected by the adjusting screw 14. By tightening the fastening nuts 15, the connection between the reinforcing component 4 and the support body is secure and robust.
