Description

Technical Field

[0001] This utility model belongs to the field of building structure, and in particular relates to a steel structure roof and wall straight tie rod connection system that can be constructed quickly. Background Technology

[0002] With the rapid advancement of industrialization and urbanization, steel structures, as a high-strength, lightweight, and environmentally friendly building material, have been widely used in the construction field. In existing steel structure buildings, the tie rods for steel roof and wall surfaces are typically composed of 12mm diameter galvanized round steel bars, nuts, bolts, and washers. Tensioning the tie rods is achieved by rotating the bolts. Due to the variety of purlin spacing and inconsistent column spacing in steel structure roof and wall surfaces, the tie rod segment lengths become inconsistent, easily affecting factory processing accuracy. The diverse types of tie rods also lead to complex on-site installation processes, a large workload, and low construction efficiency. Furthermore, on-site installation is prone to failure to tension the tie rods in a timely manner, resulting in excessive purlin deflection, uneven installation of exterior wall panels, low wall flatness, large gaps in the corrugated steel trim, and severe water seepage. This not only affects the aesthetics of industrial buildings but also poses production safety hazards. Therefore, it is necessary to optimize the existing steel structure roof and wall tie rod connection system to further improve its mechanical properties, performance, applicability, and construction aspects. Summary of the Invention

[0003] This utility model addresses the shortcomings of existing technologies by providing a steel structure roof and wall straight tie rod connection system that is easy to process and manufacture, has high construction efficiency, and is easy to adjust later, allowing for rapid construction.

[0004] To achieve the above objectives, this invention first proposes a quick-construction steel structure roof and wall straight tie rod connection system, including roof and wall purlins, tie rods, and turnbuckles; the roof and wall purlins are symmetrically provided with multiple through holes arranged along their length, the through holes matching the diameter of the tie rods; the tie rods include a pair of identical first and second tie rods, one end of which is fixed with a limiting cap larger than the outer diameter of the tie rod, and the other end is provided with a threaded section matching the turnbuckle, with the threads of the first and second tie rods being opposite; the first and second tie rods are respectively inserted into the opposite through holes of the two roof and wall purlins, and the threaded sections of the first and second tie rods are connected and tensioned by turnbuckles.

[0005] In this embodiment, the roof purlins are made of cold-formed thin-walled steel components.

[0006] In this embodiment, the roof and wall purlins include Z-shaped rolled-edge roof and wall purlins and C-shaped rolled-edge roof and wall purlins.

[0007] In this embodiment, the pull rod is a straight pull rod with a diameter of 12mm.

[0008] In this embodiment, the roof purlin is also fixed with a retaining edge or a stop block around each through hole to form a groove that matches the shape and size of the limiting cap.

[0009] In this embodiment, the limiting cap is polygonal, and more specifically, the limiting cap is hexagonal.

[0010] In this embodiment, anti-slip pads are fixed around each through hole on the roof purlin.

[0011] The present invention adopts the above structure and has the following advantages:

[0012] 1. Compared with the traditional straight tie rod system, this device only requires inserting the tie rod into the through hole of the roof and wall purlins, and then tightening the tie rod by turning the turnbuckle to tighten the entire tie rod system. The tie rods of the set length of this device can be used for various roof and wall purlin spacings, reducing processing costs. Moreover, it eliminates the need for nuts, bolts, and washers to connect to the roof and wall purlins, greatly improving installation efficiency and reducing production costs.

[0013] 2. This device has a retaining edge or a stop block around the through hole of the roof purlin to form a groove that matches the shape and size of the limit cap. When the pull bar is inserted into the through hole of the roof purlin, the limit cap is placed in the groove, thus preventing the pull bar from rotating when the turnbuckle is turned. Therefore, tensioning can be completed with only one hand, which is simple to operate and has high construction efficiency.

[0014] 3. All connections of this device are made with bolts, which makes assembly and disassembly convenient and facilitates maintenance.

[0015] In summary, this tensioning device is simple to operate, saves manpower and resources, and can be tensioned in a timely manner after the straight tie rod is installed, thus controlling the purlin deflection, ensuring the flatness of the wall surface, and making the building more aesthetically pleasing.

[0020] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of them. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0021] Furthermore, the technical solutions of the various embodiments of the present invention can be combined with each other, but only if they are based on the ability of those skilled in the art to implement them. When the combination of technical solutions is contradictory or cannot be implemented, it should be considered that such combination of technical solutions does not exist and is not within the scope of protection claimed by the present invention.

[0022] like Figures 1 to 3 As shown, a quick-construction steel structure roof and wall straight tie rod connection system includes roof and wall purlins 1, tie rods 2, and turnbuckles 3.

[0023] Tie rod 2 is made of galvanized round steel with a diameter of 12mm and material of Q235B. One end of tie rod 2 has a 20mm diameter limiting cap pre-welded to it in the processing plant, and the other end is threaded to form a threaded segment. The tie rod includes a pair of identical tie rods 21 and 22. The threaded segments of the first tie rod 21 and the second tie rod 22 are installed in pairs with opposite threads. The threaded segments of the first tie rod 21 and the second tie rod 22 are connected and tensioned by turnbuckles. Compared with the traditional straight tie rod system, this tie rod 2 no longer requires nuts, bolts, and washers to fix it to the roof and wall purlins. Therefore, the processing technology is simplified, production efficiency is improved, production costs are reduced, and it can reduce costs and increase efficiency for the project.

[0024] The roof and wall purlins 1 are made of cold-formed thin-walled steel components, preferably Z-shaped or C-shaped rolled edges. After the roof and wall purlins 1 are manufactured in the factory with through holes 4 matching the tie rods 2, they are transported to the construction site. The first tie rod 21 and the second tie rod 22 are inserted into the through holes 4 of the oppositely arranged roof and wall purlins 1. After the above steps are completed, turnbuckles 3 are installed on the opposite first tie rods 21 and second tie rods 22. By twisting the turnbuckles 3, the first tie rods 21 and second tie rods 22 are brought closer together, thereby driving the oppositely arranged roof and wall purlins 1 closer together. The tension of the entire tie rod system is achieved through multiple sets of tie rods 2.

[0025] In this embodiment, specifically: a retaining edge or a stop block is fixed around each through hole 4 on the roof purlin 1 to form a groove matching the shape and size of the limiting cap, which is a polygonal limiting cap 23. When the pull bar 2 is inserted into the through hole of the roof purlin, the limiting cap is placed in the groove, thereby preventing the pull bar from rotating when the turnbuckle is twisted.

[0026] As another structure for the self-rotation of the pull bar in this device, anti-slip pads are fixed around each through hole on the roof purlin 1. After the pull bar is inserted into the through hole of the roof purlin, the pull bar 2 is first gripped and the turnbuckle is twisted. When the limit cap comes into contact with the anti-slip pad, the friction between the anti-slip pad and the limit cap can be used to prevent the pull bar from rotating.

[0027] The efficiency of tensioning can be improved by using the two methods described above.

[0028] The above embodiments are merely illustrative examples to clearly illustrate the present invention and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all embodiments here. However, obvious variations or modifications derived therefrom are still within the scope of protection of this invention.
