Description

Technical Field

[0001] The present application relates to the technical field of building construction, and in particular to a grid installation auxiliary tool. Background Art

[0002] The grid structure is widely used in roof structures due to its advantages such as good stability and large span. It is usually composed of rods and screw balls. During construction, due to the large spacing between the rods, workers are prone to tilting when crawling on the grid holding the rods, which poses a risk of falling. The patent with announcement number CN218815385U discloses a grid installation auxiliary tool. Although it can provide a balance bar for construction workers when moving on the grid, the spacing between the rear section body and the front section body cannot be fixed due to the setting of the telescopic joint, resulting in the auxiliary tool being installed loosely on the grid, and there is still a safety hazard. For this reason, the inventor proposed a grid installation auxiliary tool. Utility Model Content

[0029] Example 1

[0030] See also Figure 1-Figure 2 This embodiment provides a grid installation auxiliary tool to solve the problem of unstable installation caused by the inability to fix the overall length of the existing grid installation auxiliary tool.

[0031] In this embodiment, the grid installation auxiliary tool includes a second rod 20 that is slidably inserted into the inside of the first rod 10. The ends of the first rod 10 and the second rod 20 both have hooks 30. The limiting plate 12 is fixedly connected to the insertion cavity 11 of the first rod 10. The second rod 20 is provided with a sliding groove 21 for clamping the limiting plate 12. The second rod 20 is rotatably connected with an adjusting cylinder 22, and the adjusting cylinder 22 is screwed onto the outside of the first rod 10.

[0032] This embodiment utilizes the sliding engagement of the limit plate 12 and the slide groove 21 to prevent the first rod 10 and the second rod 20 from rotating relative to each other. By rotating the adjustment cylinder 22, the first rod 10 can be driven to slide relative to the second rod 10, thereby locking the two at the desired position, which has the advantage of easy operation.

[0033] It should be noted that the first rod 10 and the second rod 20 are both round rod-shaped as a whole, and the hook 30 is formed by bending the ends of the first rod 10 and the second rod 20. As an example, the arc of the hook 30 is 180 degrees.

[0034] In addition, the plug-in cavity 11 is constructed into a circle along the cross section that is coaxially arranged with the first rod 10, and the limit plate 12 is fixed to the inside of the plug-in cavity 11. The limit plate 12 is constructed as a rectangular plate as a whole, and the limit plate 12 extends as a whole along the axial direction of the plug-in cavity 11. At the same time, the limit plate 12 is arranged as a whole along the diameter direction of the plug-in cavity 11.

[0035] In addition, the second rod 20 is constructed into a round rod shape that is adapted to the outer shape of the plug-in cavity 21. The outer diameter of the second rod 20 is equal to the diameter of the plug-in cavity 21. The slide groove 21 is a through groove formed on the second rod 20, and the slide groove 21 extends along the axial direction of the second rod 20. The width of the slide groove 21 is equal to the width of the limit plate 12. By utilizing this, relative rotation between the first rod 10 and the second rod 20 can be avoided, so that only axial sliding is allowed between the two, and the sliding range is the axial length of the slide groove 21. At the same time, the sliding snap-fit ​​between the limit plate 12 and the slide groove 21 can also prevent the first rod 10 and the second rod 20 from detaching.

[0036] It should also be noted that the adjustment cylinder 22 is coaxially arranged with the second rod 20, and a slot 23 for clamping the adjustment cylinder 22 is provided on the second rod 20. A clamping ring 24 clamped with the slot 23 is provided at the end of the adjustment cylinder 22. By rotating the clamping ring 24 and the slot 23, the adjustment cylinder 22 can be rotatably connected to the second rod 20 as a whole.

[0037] When in use, first hook the hook 30 on the first rod 10 on the front grid crossbar, then hook the hook 30 on the second rod 20 on the crossbar where the operator is located, and finally tighten the first rod 10 and the second rod 20 by rotating the adjustment cylinder 22. When the operator moves on the grid, the tool is used as a balance bar.

[0038] Although the embodiments of the present application have been shown and described above, it can be understood that the above embodiments are exemplary and cannot be understood as limitations on the present application. Ordinary technicians in this field can change, modify, replace and modify the above embodiments within the scope of the present application.
