Description

Technical Field

[0001] This utility model relates to the field of attached lifting scaffold facade construction technology, specifically a protective device between attached lifting scaffold and floor slab. Background Technology

[0002] Attached lifting scaffolding is a commonly used protective and construction device in building construction projects. According to safety management regulations, protective measures are required for locations with a spacing greater than 15 cm. Since attached lifting scaffolding involves working at heights, the distance between the scaffolding and the floor slab varies after installation. Traditional protection methods require personnel to attach safety nets to the attached lifting scaffolding for protection, which is dangerous, involves a large amount of work, and is difficult to install. Therefore, this utility model provides a protective device between attached lifting scaffolding and the floor slab. Utility Model Content

[0036] Please refer to the attached document. Figures 1-4 This application illustrates a protective device between an attached lifting scaffold and a floor slab, which is installed in the gap between the attached lifting scaffold and the floor slab to provide safety protection. Specifically, it includes: several parallel articulated frames, a crossbeam 6, and a protective net 8.

[0037] One end of the articulated frame is fixedly installed to the bottom end of the attached lifting scaffolding platform 9, and the second end of the articulated frame is rotatably installed with a fixing hook 3. The articulated frame generally adopts a joint structure (the horizontal mounting frame 1 and the diagonal brace 2 are hinged), and the cross frame 6 is connected to the wall through the mounting base 7.

[0038] After the protective device between the attached lifting scaffold and the floor is installed, it meets the safety management regulations that require protective treatment at locations with a spacing greater than 15 cm, thus providing safety protection for construction workers on the attached lifting scaffold platform 9.

[0039] Since the height of attached lifting scaffolding needs to be adjusted during use, the traditional netting and binding protection method has the problems of inconvenient installation and disassembly. The articulated frame designed in this utility model can be rotated and adjusted to adapt to changes in the distance between the scaffolding and the floor. Furthermore, during the movement of the attached lifting scaffolding, the second end of the articulated frame can be folded towards the location of the attached lifting scaffolding. After the attached lifting scaffolding platform 9 moves to the predetermined position, the floor slab at the second end of the articulated frame can be unfolded and the crossbeam 6 can be installed for further fixation. The operation is simple and convenient during use.

[0040] The articulated frame includes: a horizontal mounting frame 1 and a diagonal brace 2. One end of the horizontal mounting frame 1 is rotatably connected to one end of the diagonal brace 2. In some cases, the lateral density of the articulated frame is insufficient, so a protective net 8 needs to be fixedly installed on the diagonal brace 2. The protective net 8 fixedly installed on the diagonal brace 2 serves to intercept some small falling objects.

[0041] In one embodiment, the horizontal mounting bracket 1 includes: a rod 101, a threaded post 103, a first hinge seat 104, and a limiting member 102.

[0042] The first end of the pole frame 101 is fixedly provided with a first hinge seat 104, which is used to install the diagonal brace 2. The second end of the pole frame 101 is fixedly connected with a threaded column 103. The threaded column 103 is fixedly installed on the bottom end of the attached lifting scaffolding platform 9 by a nut assembly. For example, several vertical plates are fixedly connected to the bottom of the attached lifting scaffolding platform 9. Through holes are opened on the vertical plates. The threaded column 103 passes through the through holes. Nuts are installed on the threaded column 103 and on both sides of the vertical plates to achieve clamping and fixing. The side of the pole frame 101 is fixedly connected with a limit member 102, which is used to limit the installation position of the side of the attached lifting scaffolding platform 9 and the pole frame 101.

[0043] In one embodiment, the diagonal brace 2 includes: a cylinder 201 and a telescopic rod 202.

[0044] The bottom end of the cylinder 201 is rotatably connected to the first hinge seat 104 by a bolt group. One end of the telescopic rod 202 is slidably connected to the cylinder 201. The side of the cylinder 201 is threaded with screws to fix the telescopic rod 202 and the cylinder 201. According to the actual scenario, the overall length of the telescopic rod 202 and the cylinder 201 can be adjusted by sliding. After the adjustment is completed, tighten the screws to fix the telescopic rod 202 and the cylinder 201, so as to achieve the purpose of adjusting the overall length of the diagonal support frame 2. The end of the telescopic rod 202 away from the cylinder 201 is fixedly connected to the second hinge seat 203. The second hinge seat 203 is used to install the fixing hook 3.

[0045] In one embodiment, a square opening 3a is provided on the side of the fixed hook 3 away from the diagonal brace 2, and the crossbeam 6 is located inside the fixed hook 3. The two ends of the crossbeam 6 are threaded male and female openings, and multiple crossbeams 6 can be linearly connected.

[0046] In one embodiment, the mounting base 7 includes an integrally formed connecting plate 72 and a support 71. The support 71 has mounting holes, and the crossbar 6 is snapped into the inner side of the support 71. The support 71 is fixed by expansion bolts.

[0047] In one embodiment, the fixed hook 3 and the second hinge seat 203 are rotatably connected by a mounting pin 5, and a rotating wheel 4 is rotatably mounted on the mounting pin 5 on the outside of the fixed hook 3 and the inside of the second hinge seat 203. The design of the rotating wheel 4 can reduce the impact between the connection between the fixed hook 3 and the second hinge seat 203 and the floor slab.

[0048] In one embodiment, the protective net 8 includes horizontal ribs 81 and vertical ribs 82 connected in a mesh-like manner, and the horizontal ribs 81 and vertical ribs 82 are welded and fixed into a mesh.
