[0027] In order to make the purpose, technical scheme and advantages of the embodiments of the utility model clearer, the technical scheme in the embodiments of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiments of the utility model. Obviously, the described embodiments are part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model. Therefore, the following detailed description of the embodiments of the utility model provided in the drawings is not intended to limit the scope of the utility model for which protection is claimed, but merely represents selected embodiments of the utility model.

[0028] Example

[0029] Combination Figures 1 to 5 The present embodiment provides a prefabricated plate, including an integrally formed plate member 1. The plate member 1 is constructed of a C-shaped plate 2, an upper bending plate 3 and a lower bending plate 4. The upper bending plate 3 is bent in a V-shape and arranged at the end of the upper plate 5 of the C-shaped plate 2, and the lower bending plate 4 is bent in a V-shape and arranged at the end of the lower plate 6 of the C-shaped plate 2. The upper bending plate 3 and the lower bending plate 4 have the same bending angle and can be further stacked and fixed on the C-shaped plate 2.

[0030] The above-mentioned prefabricated plate can effectively enhance the stability and bearing capacity of the overall structure by further V-bending each bending part and stacking and fixing it, so that the prefabricated plate is more stable and reliable when bearing loads. The upper bending plate 3 arranged at the end of the upper plate 5 of the C-shaped plate 2 and the lower bending plate 4 arranged at the end of the lower plate 6 of the C-shaped plate 2 make the structure of the entire one-piece plate member 1 compact, optimize space utilization, and have a reasonable structural layout, which is suitable for construction projects with limited space.

[0031] Furthermore, the stacked fixed bent plates are placed on the C-shaped plate 2, thereby ensuring that the upper bent plate 3 and the lower bent plate 4 are firmly connected to the C-shaped plate 2 and are not easy to loosen, thereby ensuring the safety of the structure, making it suitable for a variety of application scenarios, especially in the field of building structures. It not only has significant improvements in structural performance, but also has advantages in economy, aesthetics and practicality, and can meet various types of needs.

[0032] In this embodiment, the plate member 1 is formed into a C-shaped plate 2, an upper bending plate 3 and a lower bending plate 4 in sequence through multiple cold bending processes. The C-shaped plate 2, the upper bending plate 3 and the lower bending plate 4 are manufactured through multiple cold bending processes, which can significantly improve the accuracy and consistency of the finished products, enhance the strength and performance of the materials, reduce manufacturing defects, improve production efficiency and cost-effectiveness, optimize the structural design, and adapt to a variety of materials and thicknesses, especially in construction steel.

[0033] In this embodiment, the width of the upper bent plate 3 is consistent with the width of the upper plate 5, and the width of the lower bent plate 4 is consistent with the width of the lower plate 6. Therefore, after being stacked and fixed, the upper and lower end faces of the C-shaped plate 2 are respectively supported more strongly by the bent plates and the plate body with the same width, which not only enhances the overall structural strength and stability, but also simplifies the manufacturing and installation process, improves the overall aesthetics and functionality, and ensures that it can function efficiently and reliably in a variety of application scenarios.

[0034] In this embodiment, the bending angle is limited to between 30° and 45°. When the bending angle is 30°, the press-fitting and fastening of the bending plate relative to the C-shaped plate 2 is more efficient, and the internal stress between them is minimal, achieving the best fastening connection effect.

[0035] In this embodiment, after being stacked and fixed, the C-shaped plate 2 and its bent plate are arranged horizontally spaced from each other, thereby further enhancing the stability of the structure, improving stress distribution, enhancing structural performance, reducing structural weight, facilitating maintenance and overhaul, and providing flexible design and application space.

[0036] Preferably, the plate member 1 is in the shape of an open strip, and the overall thickness ranges from 0.6 mm to 4 mm. The side panels 9 of the C-shaped plate 2 are 100 mm to 350 mm in height, preferably 150 mm, 200 mm or 250 mm, and the width of the upper plate 5 and the lower plate 6 of the C-shaped plate 2 is more than 90 mm. Therefore, the thickness of the plate is between 0.6 mm and 4 mm, which ensures that the plate has sufficient strength and rigidity while being lightweight, and can withstand large loads and external forces. The diversity of the height of the side panels 9 provides different options to meet different engineering requirements, making the structural design more flexible. In addition, the standardized size design facilitates large-scale production and on-site installation, reduces processing and installation time, and improves construction efficiency.

[0037] like Figures 5 to 7 As shown, in this embodiment, the upper bending plate 3 and the position corresponding to the upper plate 5 are both provided with a groove portion 7, and the lower bending plate 4 and the position corresponding to the lower plate 6 are both provided with a groove portion 7, and the groove portion 7 is used to accommodate the head of the external bolt member 8. It should be noted that the groove portion 7 is used to lock the bolt member 8 so as to more firmly lock the two plate members 1 together, and in order to prevent the bolt member 8 from being exposed, the head of the bolt member 8 can be hidden inside the groove portion 7.

[0038] It should be mentioned that the side plates 9 of the C-shaped plate 2 are correspondingly provided with at least two groove portions 7, so as to facilitate locking and fixing the C-shaped plate 2 on another plate member 1 or an external mounting frame.

[0039] Combination Figure 3 and Figure 4 ,as well as Figure 6 and Figure 7 This embodiment further provides a rectangular tube, comprising two prefabricated plates as described above. One of the plate components 1 is flipped 180° and inserted into the other plate component 1, and after being enclosed, is further laminated and fixed to form a rectangular tube.

[0040] The upper bending portion of one plate component 1 and the lower bending portion of another plate component 1 are opposite to each other, and the lower bending portion of one plate component 1 and the upper bending portion of another plate component 1 are opposite to each other, and then the bending portions are pressed together in the up / down direction to overlap each other on their respective upper plates 5 and lower plates 6.

[0041] Furthermore, the two bent portions are further pressed from top to bottom to overlap each other on their respective upper plates 5 and lower plates 6, and the two bent portions are further pressed from bottom to top to overlap each other on their respective upper plates 5 and lower plates 6, and the stacking and fixing are performed until the two side plates 9 are opposite to each other on the same horizontal plane to form a whole rectangular tube.

[0042] It should be mentioned that plug-in and superposition refers to the process of plugging and superimposing two plate components 1 in a specific way to achieve a tight combination and form an integral structure. Specifically, in the manufacturing method of the combined rectangular tube below, the specific steps of plug-in and superposition are: flip one of the plate components 1 180 degrees to ensure that the two plate components 1 can be properly matched when plugged in, and plug the flipped plate component 1 into the other plate component 1. At this time, the upper bending plate 3 of one plate component 1 and the lower bending plate 4 of the other plate component 1 are facing away from each other to ensure that they can be embedded with each other.

[0043] In the above, a whole rectangular tube fixed by stacking two plate components 1, its upper end face and lower end face are pressed and fixed by multiple bent plates and their upper and lower plates to form a supporting surface, which significantly improves the supporting strength. Under the same supporting strength, the rectangular tube formed by the bent plates stacked and fixed on the C-shaped plate 2 can reduce the steel consumption by 20% to 30%, which can greatly reduce the manufacturing cost.

[0044] The above are only preferred implementations of the present utility model. The protection scope of the present utility model is not limited to the above embodiments. All technical solutions under the concept of the present utility model belong to the protection scope of the present utility model.
