Description

Technical Field

[0001] The present application relates to the technical field of anti-skid devices, and more specifically, to an anti-skid device for building scaffolds. Background Art

[0002] The document with prior art publication number CN210767798U provides an anti-slip device for cantilever scaffolding uprights that is easy to install and fix, and improves the traditional welding process into a movable, detachable and recyclable anti-slip device, which can save materials and avoid the traditional method of welding and then cutting it off, which is time-consuming and labor-intensive. At the same time, it can also avoid the safety hazards caused by welding and cutting.

[0003] Although the device has many beneficial effects, the following problems still exist: the upper anti-skid member and the lower anti-skid member are tightened and fixed to the outside of the I-beam by bolts and nuts. When the nuts and bolts are loose, it is very easy for the anti-skid member and the lower anti-skid member to have displacement space and move arbitrarily along the direction of the I-beam, thereby reducing the anti-skid performance of the scaffolding uprights, and further reducing the protection performance for the staff using the scaffolding. In view of this, we propose an anti-skid device for building scaffolding. Utility Model Content

[0004] The embodiment of the present application provides an anti-skid device for building scaffolding, which solves the problem in the prior art that the upper anti-skid component and the lower anti-skid component are tightened and fixed to the outer side of the I-beam by bolts and nuts. When the nuts and bolts are loose, it is very easy for the anti-skid component and the lower anti-skid component to have displacement space and move arbitrarily along the direction of the I-beam, thereby reducing the anti-skid performance of the scaffolding uprights, and further reducing the technical problem of the protection performance for the staff using the scaffolding. It is easy to limit the limit plate, ensure that the limit plate does not have displacement space, prevent the limit plate, sliding sleeve and fixing tube from slipping, thereby further improving the stability of the scaffolding uprights, and further improving the technical effect of the protection performance for the staff.

[0015] Optionally, a water-permeable hole is opened through the bottom of one side of the fixed tube, and reinforcing ribs are fixedly connected to both sides of the fixed tube. The bottom of the reinforcing ribs is fixedly connected to the top of the sliding sleeve, so as to increase the strength and rigidity of the fixed tube.

[0016] By adopting the above technical solution and providing the water-permeable holes, rainwater can flow out through the water-permeable holes, thereby preventing the residual water in the fixed tube from being difficult to discharge and causing serious corrosion at the bottom of the vertical pole.

[0026] The present application is further described in detail below in conjunction with the accompanying drawings.

[0027] Reference Figure 1 and Figure 2 The embodiment of the present application discloses an anti-skid device for a building scaffold. The anti-skid device for a building scaffold comprises: an I-beam 1;

[0028] An anti-slip mechanism 2 is provided on the outer side of the I-beam 1 to increase the stability of the cantilever scaffolding;

[0029] The anti-skid mechanism 2 includes a sliding sleeve 21, which is slidably mounted on the outside of the I-beam 1. The bottom of the sliding sleeve 21 is detachably connected to a limiting plate 22. The top of the sliding sleeve 21 is fixedly connected to a fixing tube 25. One side of the fixing tube 25 is threadedly connected to a first threaded rod 26 for fixing the scaffolding uprights. A mounting plate 27 is provided at the bottom of the I-beam 1. The bottom of the mounting plate 27 is fixedly connected to a limiting rod 28. The bottom of the limiting plate 22 is penetrated by an opening 23 for cooperating with the limiting rod 28, thereby facilitating further improving the anti-skid performance of the scaffolding uprights.

[0030] Reference Figure 1 and Figure 3 The sliding sleeve 21 and the limiting plate 22 are both fixedly connected with connecting plates 24. A through hole is penetrated through the top of the connecting plate 24. A bolt is arranged in the through hole. A nut is arranged on the outer threaded sleeve of the bolt, which is convenient for the staff to quickly connect the sliding sleeve 21 and the limiting plate 22.

[0031] Reference Figure 1 and Figure 3 The two sides of the bottom of the sliding sleeve 21 are respectively located inside the two sides of the I-beam 1, and the two sides of the bottom of the inner wall of the sliding sleeve 21 are respectively in contact with the top of the inner wall of the two sides of the I-beam 1, so that the sliding sleeve 21 can only move along the direction of the I-beam 1.

[0032] Reference Figure 2 and Figure 4 A slide groove is provided at the bottom of the I-beam 1, and a slider 3 is slidably connected in the slide groove. The bottom of the slider 3 is fixedly connected to the bottom of the mounting plate 27. A pushing member for pushing the mounting plate 27 to move is provided on one side of the bottom of the I-beam 1, thereby flexibly adjusting the installation position of the scaffolding uprights.

[0033] Reference Figure 2 and Figure 4 The cross-sections of the slide groove and the slider 3 are both T-shaped, thereby preventing the slider 3 from escaping from the slide groove.

[0034] Reference Figure 4 The pushing member includes a support plate 4 and a second threaded rod 5. The support plate 4 is fixedly connected to one side of the bottom of the I-beam 1. A threaded hole is penetrated through one side of the support plate 4. The second threaded rod 5 is threadedly connected to the threaded hole. One end of the second threaded rod 5 is rotatably connected to one side of the mounting plate 27, so as to facilitate pushing the mounting plate 27 to move toward or away from the support plate 4.

[0035] Reference Figure 4 The other end of the second threaded rod 5 is fixedly connected with a knob, and the outer side of the knob is provided with anti-slip grooves to prevent the staff from slipping.

[0036] Reference Figure 1 and Figure 2 The top of the fixing tube 25 is open, and the bottom of the fixing tube 25 is closed, so that it is easy to insert the vertical pole of the scaffold.

[0037] Reference Figure 3 Both sides of the fixed tube 25 are fixedly connected with reinforcing ribs 6 , and the bottom of the reinforcing ribs 6 is fixedly connected to the top of the sliding sleeve 21 , so as to increase the strength and rigidity of the fixed tube 25 .

[0038] Reference Figure 3 A water-permeable hole 7 is formed through the bottom of one side of the fixing tube 25 to prevent rainwater in the fixing tube 25 from gathering inside the fixing tube 25 .

[0039] The implementation principle of the anti-skid device for building scaffolding in the embodiment of the present application is as follows: when it is necessary to install the vertical pole of the cantilever scaffolding, the staff can screw the second threaded rod 5. Since the second threaded rod 5 is threadedly connected to the threaded hole, and one end of the second threaded rod 5 is rotatably connected to the mounting plate 27, the mounting plate 27 can be pushed to move. The movement of the mounting plate 27 can drive the slider 3 and the limit rod 28 to move. When the limit rod 28 moves to the specified position, the staff can slide the sleeve 21 on the outside of the I-beam 1. The sliding sleeve 21 is moved sideways until it moves to the top of the limiting rod 28. Then the staff can align the opening 23 at the bottom of the limiting plate 22 with the limiting rod 28, so that the limiting plate 22 is sleeved on the outside of the limiting rod 28. Then, the two adjacent connecting plates 24 are connected by bolts and nuts, so that the sliding sleeve 21 is connected to the limiting plate 22. Finally, the vertical pole is inserted into the inner side of the fixing tube 25, and the first threaded rod 26 is screwed to fix the vertical pole on the inner side of the fixing tube 25, so as to improve the anti-slip performance of the vertical pole.

[0040] The embodiment of the present application provides an anti-skid device for a building scaffold. By setting an anti-skid mechanism 2, it is possible to limit the limit plate 22, ensure that there is no displacement space for the limit plate 22, prevent the limit plate 22, the sliding sleeve 21 and the fixed tube 25 from slipping, thereby facilitating further improving the stability of the scaffold uprights, and further facilitating further improving the protection performance for the staff.
