Technical Field
[0001] This utility model relates to the field of building engineering technology, specifically to a building safety railing. Background Technology
[0002] During construction, it is necessary to surround the construction site to ensure that unauthorized personnel cannot enter. Currently, safety railings are often used for this protection method. However, safety railings are often one-piece structures, and when multiple railings are spliced together, there may be a gap between the last railing and the wall or other objects. In this case, it is difficult to place another railing between them, which reduces the effectiveness of subsequent protection. In addition, the splicing of safety railings is often done by bolt fixing, which makes subsequent disassembly and assembly work inconvenient. Utility Model Content
[0003] The purpose of this utility model is to provide a building safety railing to solve the problems existing in the background art.
[0004] To achieve the above objectives, this utility model provides the following technical solution: a building safety railing, comprising a first vertical bar and a second vertical bar, and further comprising:
[0005] A guardrail 1 is fixed to one side of the first vertical bar. The back of the guardrail 1 is provided with sliding grooves at the top and bottom. A guardrail 2 is fixed to one side of the second vertical bar. The surface of the guardrail 2 is fixed with sliders at the top and bottom. The surface of the sliders is slidably connected to the inside of the sliding grooves.
[0006] The insert plate is fixed on the upper and lower sides of the other side of the first vertical rod, and the upper and lower sides of the other side of the second vertical rod are both fixed with concave plates for insertion into the insert plate;
[0007] A torsion disc is set at the top of the second vertical rod. A screw is fixed at the bottom of the torsion disc. Screw sleeves are threadedly connected to the upper and lower surfaces of the screw. A pressure plate is fixed to the surface of the screw sleeve, and the inner side of the pressure plate is movably connected to the surface of the second vertical rod.
[0008] Preferably, a limiting groove is formed on the back of the second vertical rod, and the inner side of the pressure plate is slidably connected to the inside of the limiting groove.
[0009] Preferably, a connecting plate is fixed to the top of the second vertical rod, and the connecting plate is internally threaded with a fastening bolt for fixing the torsion disc.
[0010] Preferably, a folding plate is fixed on opposite sides of both the upper and lower sliders, and the other end of the folding plate passes through one side of the guardrail and is movably connected to its interior. The folding plate is internally threaded with a fixing bolt.
[0011] Preferably, a locking block is fixed to the bottom of the pressure plate, and a locking groove is provided on the top of the insertion plate, with the surface of the locking block engaging with the interior of the locking groove.
[0012] Preferably, bolts are threaded to the front and rear sides of both the bottom ends of the first and second vertical rods.
[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0014] 1. This utility model uses a slider that moves within a groove to adjust the length between the first and second vertical bars according to the gap between the safety railing and the wall or other object, so that one side of the safety railing can fit against the side of the wall or other object. This not only allows the safety railing to be adjusted according to the area it covers, but also improves the protective effect of the safety railing.
[0015] 2. In this utility model, after one end of the insert plate is inserted into the inner side of the concave plate, the screw surface is connected to the thread inside the screw sleeve, which can drive the pressure plate to move downward, so that the pressure plate can press the insert plate inserted into the concave plate, thus reducing the trouble of disassembling and assembling adjacent safety railings.

Detailed Implementation
[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0022] Please see Figure 1-4 As shown, a building safety railing includes a first vertical bar 1 and a second vertical bar 2. A guardrail 3 is fixed to one side of the first vertical bar 1. The guardrail 3 has grooves 4 on both the upper and lower sides of its back. A guardrail 5 is fixed to one side of the second vertical bar 2. Slider blocks 6 are fixed to both the upper and lower sides of the surface of the guardrail 5. The surface of the sliders 6 is slidably connected to the inside of the grooves 4. A folded plate 7 is fixed to the opposite side of the two sliders 6. The other end of the folded plate 7 passes through one side of the guardrail 3 and is movably connected to its interior. A fixing bolt 20 is threaded into the interior of the folded plate 7. Thus, after the length distance between the guardrail 5 and the guardrail 3 is adjusted, the fixing bolt 20 can be rotated to fix the guardrail 3 and the guardrail 5. The other side of the first vertical bar 1 has grooves 4 on both the upper and lower sides of its back. A fixed insert plate 8 is provided. On the other side of the second vertical rod 2, both the upper and lower sides are fixed with recessed plates 9 for insertion into the insert plate 8. A torsion plate 10 is provided at the top of the second vertical rod 2. A screw 11 is fixed at the bottom of the torsion plate 10, and the other end of the screw 11 is rotatably connected to the inner wall of the second vertical rod 2. Threaded sleeves 12 are threaded to the upper and lower sides of the surface of the screw 11. A pressure plate 13 is fixed to the surface of the threaded sleeve 12, and the inner side of the pressure plate 13 is movably connected to the surface of the second vertical rod 2. A locking block 15 is fixed to the bottom of the pressure plate 13. A locking groove 14 is provided at the top of the insert plate 8. The surface of the locking block 15 is used in conjunction with the inside of the locking groove 14. Thus, when the pressure plate 13 and the top of the insert plate 8 are attached, the locking block 15 will enter the inside of the locking groove 14, thereby stably pressing the insert plate 8 and the recessed plate 9 together.
[0023] The back of the second vertical rod 2 has a limiting groove 19. The inner side of the pressure plate 13 is slidably connected to the inside of the limiting groove 19, so that the pressure plate 13 can be auxiliaryly limited and facilitate its up and down movement.
[0024] The top of the second vertical rod 2 is fixed with a connecting plate 16, and the connecting plate 16 is internally threaded with a fastening bolt 17 for fixing the twisting disc 10. Thus, after the twisting disc 10 rotates, the fastening bolt 17 can be rotated to fix the position of the twisting disc 10.
[0025] Bolts 18 are threaded onto the front and rear sides of both the bottom ends of the first vertical rod 1 and the second vertical rod 2, which can stably fix the positions of the first vertical rod 1 and the second vertical rod 2.
[0026] It is worth noting that the technical features proposed in this technical solution should be regarded as prior art. The specific structure, working principle, and possible control methods and spatial arrangement of these technical features can be selected using conventional methods in the field. This technical solution will not elaborate further.
[0027] Working principle: When using, first measure the required length of the surrounding protection. Then, based on the longest length of guardrail 3 and guardrail 5 after they are pulled apart, prepare several safety guardrails. Next, fix the first vertical bar 1 first, and then remove the limit between guardrail 3 and guardrail 5 by fixing bolt 20. Then, pull guardrail 5 outward to move it to the designated position. Then fix the second vertical bar 2. Then, insert the insert plate 8 on one side of the other first vertical bar 1 into the concave plate 9 on the right side of the second vertical bar 2. Then, rotate the torsion plate 10, which will drive the screw 11 to rotate, and at the same time drive the screw sleeve 12 to rotate, which will drive the pressure plate 13 to move downward, thereby fixing the insert plate 8 and the concave plate 9. Finally, repeat this process to splice and install.
