Description

Technical Field

[0001] This utility model patent relates to the field of building construction technology, and in particular to an assembled opening protection door. Background Technology

[0002] As the adoption rate of elevators increases with the requirements of standardized construction, the requirements for safety management are also becoming more stringent. Protective measures for elevator openings are crucial to preventing falls from heights. In the past, temporary protection for elevator openings was often achieved by erecting scaffolding and using welded steel mesh and square steel pipes to form fixed fences. These methods are time-consuming, labor-intensive, and economically inefficient, with high transportation costs, poor turnover, and installation often using nail guns for wall fixing, which greatly hinders operations that require temporary opening.

[0003] A Chinese utility model patent application with number 202122109159.5 proposes a protective door for elevator shaft openings. The protective mechanism includes two screw rods, each with several protective plates arranged in a linear array. Each protective plate has a through hole that matches the screw rod. The ends of the two screw rods are bolted with nuts. The top and bottom ends of the protective plates on the two screw rods are connected to the wall via connecting plates. This solution uses external expansion bolts. Common masonry opening materials on construction sites include aerated concrete blocks and porous shale bricks. Expansion bolts are not very secure on these materials, making the protective door prone to loosening and falling off, greatly increasing the safety hazards of the opening. The method of fixing with expansion bolts also damages the structure itself, especially brittle masonry.

[0004] Therefore, there is an urgent need to invent an assembled opening protection door that is convenient to transport, easy to assemble, easy to install and disassemble, reusable, and applicable to various opening sizes. Utility Model Content

[0005] This utility model discloses an assembled opening protection door. By setting the doorposts, crossbars, adjustable fasteners and clamps to be installed in a detachable and fixed manner, and by setting anti-slip rubber pads on the inside of the clamps, it solves the shortcomings of existing protection doors, such as lack of standardization of protection, low requirements and poor protection effect. At the same time, it can achieve standardized production and maintenance, and is convenient to transport, simple to assemble, easy to disassemble and reassemble, reusable and modular, and can be used for assembly of various opening sizes.

[0006] This utility model discloses an assembled opening protection door, which is used in conjunction with a wall. The assembled opening protection door includes: doorposts, crossbars, adjustable fasteners, and clamps. There are two doorposts with pre-drilled through holes at equal intervals. The inner diameter of the first crossbar is smaller than the outer diameter of the second crossbar. The crossbar is detachably connected to the doorposts. The connecting section of the first crossbar and the second crossbar is fastened by adjustable fasteners. The upper and lower ends of the doorposts are detachably connected to the wall by clamps.

[0007] Preferably, there are two doorposts, and one side of each doorpost has a rectangular hole 1 with equal spacing. A bakelite fastener is installed in the rectangular hole 1, and a rectangular hole 2 is provided on the adjacent surface of the rectangular hole 1.

[0008] Preferably, the crossbar is detachably connected to the doorpost via a bakelite fastener.

[0009] Preferably, the clamp includes: a first clamp, a second clamp, a pin, a hook, and a fastening bolt. Both the first clamp and the second clamp are "L"-shaped tubular structures. The outer diameter of the first clamp is smaller than the inner diameter of the second clamp. The first clamp has a pin hole in the vertical direction, and the second clamp has a pin hole in the vertical direction, with multiple pin holes arranged at equal intervals. The second clamp has a threaded hole in the horizontal direction. The fastening bolt is bolted to the threaded hole. The hook is an "L"-shaped structure, and the shorter side of the hook is welded and fixed to the second clamp.

[0010] Preferably, the end of the fastening bolt is welded with an anti-slip rubber pad, and the inner side of the clamp in the horizontal direction is welded with an anti-slip rubber pad.

[0011] Preferably, the top of the pin is provided with a stop to prevent the plug from falling off.

[0012] Preferably, the bakelite fastener includes: a bakelite block with an internal nut and a bakelite block with an internal bolt.

[0013] Beneficial effects

[0014] This utility model improves the quick-assembly opening protection door by proposing that the doorposts, crossbars, adjustable fasteners, and clamps are all detachable and can be installed together. The installation components can achieve modularization and standardization, making the modules convenient to transport, easy to assemble and disassemble. In case of module damage, the damaged module can be replaced individually for quick repair, thereby improving the reusability of the modules.

[0015] This utility model improves the clamp by providing anti-slip rubber pads on the inner side of the clamp and the end of the fastening bolt. The pads are matched with the first and second insertion holes and fixed with pins. The anti-slip rubber pads enhance the friction between the clamp and the wall, solving the problem of poor stability caused by drilling holes in aerated blocks and porous shale bricks with expansion bolts in the traditional method. This eliminates safety hazards. At the same time, the installation and disassembly process of this utility model does not damage the wall structure itself. Attached Figure Description

[0036] The adjustable fastener 4 is a 100mm long steel pipe with a diameter of 42mm and a wall thickness of 2mm. It has a 10mm round hole in the middle, a 10-thread nut inside, and a 40mm long push-in bolt.

[0037] Cards

[0038] (1) The clamp 5 is made of 30mm*30mm*2mm square steel pipe. Take 150mm long section and 270mm long section respectively. Weld the square steel pipe into an L-shape at 90° to form clamp 501.

[0039] (2) The clamp 5 is made of 34mm*34mm*2mm square steel pipe. Take 150mm long section and 270mm long section respectively. Weld the square steel pipe into an L-shape at 90° to form clamp 502.

[0040] (3) Pin hole 506: A round hole with a diameter of 8mm is made 50mm away from the free end of a 270mm long 30mm square steel pipe, perpendicular to the L-shape.

[0041] (4) Pin hole 2 507: 50mm from the free end of a 270mm long and 34mm long square steel pipe, one 8mm diameter round hole is made at a distance of 50mm from the corner in the direction perpendicular to the L-shape. The total number of holes is 4.

[0042] (5) Pin 503: Made of 6mm diameter round steel, with a top bend or bend to prevent it from falling off;

[0043] (6) 150mm long clamp 2 502 has a 12mm diameter threaded hole opened along the "L" parallel direction, 50mm from the free end, with a built-in 16-thread nut, and a 55mm long fastening bolt 505. The bolt end is welded with an anti-slip rubber pad 508.

[0044] (7) 150mm long clamp 2 502 along the "L" parallel direction, 100mm from the free end, weld hook 504;

[0047] like Figure 1-5As shown, in this utility model, there are two doorposts 2. Horizontal tube 1 301 is detachably connected to the through hole of the left doorpost 2 via a bakelite fastener 203. Horizontal tube 2 302 is detachably connected to the through hole of the right doorpost 2 via a bakelite fastener 203. Multiple sets of horizontal tube 2 302 are inserted into horizontal tube 1 301. The connection between the upper horizontal tube 2 302 and horizontal tube 1 301 is fixed by an adjustable fastener 4. The connection between the lower horizontal tube 2 302 and horizontal tube 1 301 is also fixed by an adjustable fastener 4. Clip 1 501 is inserted into clip 2 502 and aligns with the corresponding wall 1. The clamps are positioned and the gap between the first clamp 501 and the second clamp 502 is tightened to obtain the predetermined length. After the positions of the first pin hole 506 and the second pin hole 507 are aligned, they are fixedly connected by the pin 503. Because the inner side of the first clamp 501 in the horizontal direction and the end of the fastening bolt 505 are welded with anti-slip rubber pads 508, a large frictional force is generated when clamping the wall 1. The hook 504 in the clamp 5 is inserted into the rectangular hole 202 of the door post 2, which forms a support for the door post 2 and the crossbar 3 after they are fixed, so that the assembled opening protection door is firmly installed in the elevator opening.
