Description
Technical Field
[0001] This utility model relates to the field of building construction, and in particular to a quick-assembly keel structure for prefabricated lightweight partition walls. Background Technology
[0002] Prefabricated lightweight partition walls are a modern interior partitioning solution for buildings. They are made by prefabricating lightweight, high-strength partition wall panels in a factory and then quickly assembling them on site. This partition wall system is widely used in modern buildings because of its fast construction speed, stable quality, and good environmental performance.
[0003] During the construction of prefabricated lightweight partition walls, the keel frame needs to be assembled first. However, traditional keel frames are usually installed on-site by welding square steel pipes or steel sections, which makes the keel construction process very inconvenient and affects construction efficiency, and needs to be improved. Utility Model Content
[0004] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a quick-assembly keel structure for prefabricated lightweight partition walls, which can improve construction efficiency.
[0005] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a quick-assembly keel structure for prefabricated lightweight partition walls, comprising:
[0006] The main frame, in a rectangular shape, is vertically installed within the prefabricated building.
[0007] Vertical beams are installed vertically and spaced apart within the main frame;
[0008] The locking component includes a locking tube, a locking plate, a mounting plate, and a locking hook. The locking tube is vertically slidably connected to the vertical beam. The locking plate is horizontally disposed at the end of the vertical beam. The mounting plate is horizontally disposed on the main frame. The locking hook is disposed on the mounting plate and is used to pass through and hook the locking plate.
[0009] A horizontal beam is horizontally positioned between the main frame, the vertical beam, and adjacent vertical beams. Both ends of the horizontal beam are provided with insert rods, and the main frame and the vertical beams are provided with insertion holes for inserting the insert rods.
[0010] In a preferred embodiment, the present invention can be further configured as follows: a pair of driving blocks are horizontally slidably connected inside the vertical beam, the opposite sides of the pair of driving blocks are inclined, the lower end of the locking tube is inclined and matches the inclined surface of the driving block, both ends of the vertical beam are horizontally rotatably connected to a bidirectional screw, and the pair of driving blocks are threadedly connected to the bidirectional screw.
[0011] In a preferred embodiment, the present invention can be further configured such that: the mounting plate is horizontally slidably connected to the main frame, and the mounting plate is provided with screws that press the main frame.
[0012] In a preferred embodiment, the present invention can be further configured such that the crossbeam includes end rods and intermediate rods, and the two ends of the intermediate rods are respectively threaded to a pair of end rods.
[0013] In a preferred embodiment, the present invention can be further configured such that a mounting hole is provided at the center of the intermediate rod.
[0014] In a preferred embodiment, the present invention can be further configured such that: the outer wall of the insertion rod is provided with an elastic locking block, the locking block pressing against the inner sidewall of the main frame and the vertical beam.
[0015] In summary, this utility model has the following beneficial effects:
[0016] 1. By setting sliding locking tubes at both ends of the vertical beam and using snap-fit locking hooks, the vertical beam can be quickly installed and fixed. At the same time, the horizontal beam is fixed by plugging in, so as to quickly fix the horizontal beam. This completes the welding-free installation and fixing of the entire keel, thereby improving construction efficiency.
[0017] 2. By setting up a sliding connection mounting plate, the spacing between the vertical beams can be adjusted, and in conjunction with the telescopic horizontal beam, different construction needs can be met, improving practicality. Attached Figure Description

[0021] The present invention will be further described in detail below with reference to the accompanying drawings.
[0022] like Figure 1 , Figure 2 As shown, a quick-assembly keel structure for prefabricated lightweight partition walls includes a main frame 1, vertical beams 2, locking components 3, and horizontal beams 4. The main frame 1 is rectangular and vertically installed within the prefabricated building, and the vertical beams 2 are vertically installed and spaced apart within the main frame 1.
[0023] like Figure 1 , Figure 2 As shown, the locking component 3 includes a locking tube 31, a locking plate 32, a mounting plate 33, and a locking hook 34. The locking tube 31 is vertically slidably connected to the vertical beam 2, and the locking plate 32 is horizontally disposed at the end of the vertical beam 2. The mounting plate 33 is horizontally disposed on the main frame 1, and the locking hook 34 is disposed on the mounting plate 33 and is used to pass through and hook the locking plate 32.
[0024] like Figure 1 , Figure 2 As shown, a pair of driving blocks 21 are horizontally slidably connected inside the vertical beam 2, with the opposite sides of the driving blocks 21 being inclined. The lower end of the locking tube 31 is inclined and matches the inclined surface of the driving blocks 21. Both ends of the vertical beam 2 are horizontally rotatably connected to bidirectional screws 22, and the pair of driving blocks 21 are threadedly connected to the bidirectional screws 22.
[0025] like Figure 1 , Figure 2 As shown, the horizontal beam 4 is horizontally positioned between the main frame 1 and the vertical beam 2, as well as between adjacent vertical beams 2. Both ends of the horizontal beam 4 are equipped with insertion rods 41. The main frame 1 and the vertical beam 2 are provided with insertion holes 42 for inserting the insertion rods 41. The outer wall of the insertion rod 41 is provided with elastic locking blocks 43, which press against the inner walls of the main frame 1 and the vertical beam 2.
[0026] When it is necessary to construct the keel structure, first fix the main frame 1, then take out the vertical beam 2 and place it vertically inside the main frame 1. Then place the horizontal beam 4 between the vertical beam 2 and the main frame 1, and insert the insert rods 41 at both ends of the horizontal beam 4 into the insert holes 42 on the vertical beam 2 and the main frame 1. Under the snapping action of the locking block 43, the horizontal beam 4 is fixed and the vertical beam 2 is supported and limited.
[0027] Then, the bidirectional screw 22 is rotated to bring the pair of drive blocks 21 closer together. The drive blocks 21 press the locking tube 31 to slide outward, and finally the locking hook 34 passes through the locking plate 32 on the locking tube 31, thus achieving the connection and fixation between the vertical beam 2 and the main frame 1. Then, another vertical beam 2 and multiple horizontal beams 4 are removed, and the process is repeated to complete the construction of the entire keel structure.
[0028] Therefore, by setting sliding locking tubes 31 at both ends of the vertical beam 2 and using locking hooks 34 for snap-fit fixing, the vertical beam 2 can be quickly installed and fixed. At the same time, the horizontal beam 4 is fixed by plugging in, so as to quickly fix the horizontal beam 4, thus completing the welding-free installation and fixing of the entire keel and improving the construction efficiency.
[0029] like Figure 1 , Figure 2As shown, the mounting plate 33 is horizontally slidably connected to the main frame 1, and screws 35 are provided on the mounting plate 33 to press the main frame 1. The crossbeam 4 includes end rods 44 and intermediate rods 45. The two ends of the intermediate rod 45 are respectively threaded to a pair of end rods 44, and a mounting hole 46 is provided in the middle of the intermediate rod 45.
[0030] When installing vertical beams 2 with different spacings, a tool can be inserted into the mounting hole 46, and the intermediate rod 45 can be rotated using the lever principle to adjust the spacing between a pair of end rods 44. Then, the screws 35 are loosened to adjust the position of the mounting plate 33, thereby adjusting the spacing between the vertical beams 2. Finally, the telescopically adjusted horizontal beam 4 and vertical beams 2 are installed to meet different construction needs and improve practicality.
[0031] The specific embodiments are merely explanations of this utility model and are not intended to limit it. After reading this specification, those skilled in the art can make modifications to these embodiments without contributing any inventive step, but such modifications are protected by patent law as long as they fall within the scope of the claims of this utility model.
