Description

Technical Field

[0001] This utility model relates to the field of building truss construction technology, and more specifically to an improved temporary support frame for tensioned tube trusses. Background Technology

[0002] Prestressed tensioned tube trusses are widely used in large-span industrial and public buildings. In traditional construction, the prestressed cables at the bottom of the truss need to pass through the support frame. After the tensioned tube truss is assembled, the support frame above the prestressed cables needs to be removed. After the truss is moved away from the support frame, the removed support frame sections are reassembled to assemble the next tensioned tube truss. This method requires frequent assembly and disassembly of the support frame, resulting in low construction efficiency, affecting the construction progress, and wasting construction resources. Utility Model Content

[0003] 1. Technical problem to be solved by the utility model

[0004] To address the problem of low construction efficiency caused by frequent assembly and disassembly of support frames during the assembly and construction of existing prestressed tensioned tube trusses, this utility model provides an improved temporary support frame for tensioned tube trusses. By improving the cable-passing section where the prestressed cables pass through the support frame segments, the frequent assembly and disassembly of the support frame during construction is avoided, thereby improving construction efficiency and achieving the goals of convenient construction and saving construction resources.

[0005] 2. Technical Solution

[0006] To achieve the above objectives, the technical solution provided by this utility model is as follows:

[0007] An improved temporary support frame for a tensioned tube truss includes multiple standard assembly sections that are stacked and fixedly connected, and a cable-through section connected to the top of the uppermost standard assembly section. The cable-through section is a square frame support structure, with its side support columns being rotating pillars capable of rotating up and down, allowing the prestressed cables to slide out of the cable-through section. In practical use, after the tensioned tube truss is assembled, the prestressed cables are tensioned, causing the tensioned tube truss to arch upwards under the tension force, and the bottom of the truss detaches from the top support point of the support frame. The rotating pillars then rotate, allowing the tensioned tube truss and prestressed cables to slide out of the temporary support frame through the opening in the cable-through section. The cable-through section at the top of the temporary support frame does not require frequent disassembly and reassembly, achieving the effects of convenient construction and saving construction resources.

[0008] A further technical solution involves a reinforcing beam fixedly connected laterally to the inner side of the cable-through section, with additional vertical rods fixedly connected between the upper and lower reinforcing beams to increase the load-bearing capacity of the cable-through section and ensure that the entire temporary support frame meets structural safety requirements after the rotating column flips over.

[0009] A further technical solution involves fixing the rotating column to the cable section via a pin hinge, which enables rotation and is simple to operate and highly efficient.

[0010] A further technical solution involves symmetrically arranging the upper and lower pins. The upper pin enables the rotation of the rotating column, while the lower pin locks the rotating column to prevent it from dislodging.

[0011] A further technical solution involves a top hook that is fixedly connected to the upper part of the cable section. After the rotating column is flipped, it will be hooked and fixed to prevent the rotating column from tipping over due to its own weight when the prestressed cable leaves the temporary support frame.

[0012] 3. Beneficial effects

[0013] Compared with the prior art, the technical solution provided by this utility model has the following advantages:

[0014] This utility model discloses an improved temporary support frame for tensioned tube trusses. By modifying the support frame structure at the section where the cable passes through, the two uprights of the support frame at the section where the cable passes through are changed to rotatable uprights connected by pins. After the tensioned tube truss is installed, the lower pin of the two uprights is pulled out, and the upright rotates around the upper pin and is fixed to the top with a temporary hook, leaving space for the cable to leave the support frame. After the tensioned tube truss and cable have completely left the support frame, the two rotatable uprights are returned to their original positions and fixed with pins. This avoids frequent disassembly and assembly of the support frame, achieving the effects of convenient construction and saving construction resources. Attached Figure Description

[0022] To further understand the contents of this utility model, a detailed description of the utility model is provided in conjunction with the accompanying drawings.

[0023] Example 1

[0024] The improved tensioned tube truss temporary support frame in this embodiment, such as Figure 1 , 2 As shown, it includes multiple standard assembly sections 3 that are stacked and fixedly connected, and a cable-through section 9 connected to the top of the uppermost standard assembly section 3. The cable-through section 9 is a square frame support structure, and the supporting vertical rods on its side are rotating columns 5 that can be flipped up and down, so that the prestressed cable 2 can be moved out of the cable-through section 9.

[0025] In this embodiment, the temporary support frame, when used, is assembled after the tensioned tube truss 10 is completed, as follows: Figure 3 As shown, the prestressed cable 2 is prestressed and tensioned. Under the action of the tension force, the tensioned tube truss 10 arches upward, and the bottom of the truss detaches from the top support point 1 of the support frame; as shown... Figure 4 , 5 As shown, rotating column 5 flips over, and the tensioned tube truss 10 and prestressed cable 2 move away from the temporary support frame through the opening of cable-passing section 9. After the prestressed cable 2 detaches, as... Figure 6 As shown, rotating column 5 returns to its original position, and the cable section 9 on the upper part of the temporary support frame does not need to be frequently disassembled and reassembled, achieving the effect of convenient construction and saving construction resources.

[0026] Example 2

[0027] The improved tensioned tube truss temporary support frame in this embodiment has the same basic structure as in Embodiment 1, but the differences or improvements are as follows: Figure 1-6 As shown, a reinforcing beam 7 is fixedly connected laterally to the inner side of the cable-through section 9. An additional vertical rod 4 is fixedly connected between the upper and lower reinforcing beams 7 to increase the load-bearing capacity of the cable-through section 9 and ensure that the entire temporary support frame meets structural safety requirements after the rotating column 5 is flipped. The rotating column 5 is hinged to the cable-through section 9 via a pin 6, and the flipping is achieved through the pin 6, which is simple to operate and highly efficient. The pins 6 are symmetrically arranged at the top and bottom. The upper pin 6 enables the flipping of the rotating column 5, and the lower pin 6 acts as a lock to prevent the rotating column 5 from dislodging. A top hook 8 is fixedly connected to the upper part of the cable-through section 9 to hook and fix the rotating column 5 after it is flipped, preventing the rotating column 5 from tipping over due to its own weight when the prestressed cable 2 leaves the temporary support frame.

[0028] The temporary support frame in this embodiment, when used in practice, is as follows: Figure 1-6 As shown, after the tensioned tube truss 10 is installed, the lower pin 6 of the rotating column 5 connected by the two pins 6 is pulled out. The column rotates around the upper pin 6 and is fixed to the top by the top hook 8, leaving space for the prestressed cable 2 to leave the support frame. After the tensioned tube truss 10 and the prestressed cable 2 have completely left the temporary support frame, the two rotatable columns are returned to their positions and fixed with pins 6. This avoids frequent disassembly and assembly of the support frame, achieving the effect of convenient construction and saving construction resources.

The actual structure and manufacturing steps are not limited to these. Therefore, if those skilled in the art are inspired by this description and design similar structures and embodiments without departing from the spirit of the invention, such designs should fall within the protection scope of the present invention.
