Description

Technical Field

[0001] The utility model relates to a fastening device, in particular to a detachable truss fastener. Background Art

[0002] Trusses are common support structures in building structures. However, traditional fasteners require a large number of bolts and welding during installation and disassembly, which is not only time-consuming and laborious, but also once the truss needs to be replaced or repaired, complex disassembly and welding work must be carried out again, which brings great inconvenience to building maintenance. Therefore, how to upgrade the traditional truss fastener with a new design is a problem worthy of consideration for designers.

[0003] After retrieval, CN208202163U discloses a square tube truss connection structure, which is applicable to the connection of the square tube truss part for belt conveyor load-bearing in factory production and assembly installation. By adjusting the panel structure, the fast assembly of the truss at the installation site can be realized by using fasteners, and the structure has good stress and less material consumption. However, it cannot reduce the risk of disassembly, maintenance and replacement of the subsequent connection structure. Summary of the Utility Model

[0009] Preferably, in the above detachable truss fastener, an elastic spring is arranged between the inner wall of the main body 2 and the socket 3.

[0010] Preferably, in the above detachable truss fastener, a concave opening is arranged on the pressure-bearing member 1.

[0011] Preferably, in the above detachable truss fastener, the applicable truss diameter range of the socket 3 is 20 - 60 cm.

[0012] The utility model has the following beneficial effects:

[0013] In the present utility model, through the cooperation among the connecting component, the locking mechanism and the plug connector, the detachable truss fastener can achieve quick installation and disassembly, ensure the firmness of the connection, and have no negative impact on the work of the truss. By adopting different connection technologies and locking mechanisms, suitable fasteners can be selected according to specific requirements. These fasteners can improve work efficiency, reduce the installation and disassembly costs, and are applicable to various truss application scenarios. BRIEF DESCRIPTION OF THE DRAWINGS

[0017] 1, pressure-bearing member; 2, main body; 3, socket; 4, fastening bolt; 5, U-bolt; DETAILED DESCRIPTION OF THE EMBODIMENTS

[0018] Next, the technical solutions in the present utility model application will be clearly and completely described in conjunction with the drawings in the present utility model application. Obviously, the described application is only a part of the present utility model application, rather than all of the present utility model application. All other applications obtained by those of ordinary skill in the art based on the application in the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0019] Refer to Figure 1 and Figure 2 , a detachable truss fastener disclosed in the present utility model:

[0020] As Figure 1 , 2 shown, the present application discloses a detachable truss fastener, including a main body 2 and a fastening bolt 4 connected to the bottom end of the main body 2. A pressure-bearing member 1 is welded to the top end of the main body 2, and a socket 3 is arranged in the middle of the main body 2; the fastening bolt 4 can penetrate the bottom end of the main body 2, and a U-bolt 5 for connecting two main bodies 2 of the fastener into one body is arranged on the main body 2.

[0021] When the truss fastener is in use, place the socket 3 of the truss fastener at a predetermined position on the truss. The elastic spring provided between the inner wall of the main body 2 and the socket 3 adapts to trusses of different diameters, adjusts the position to be fastened, align the fastening bolt 4 with the corresponding hole position of the truss, and fix the main body 2 of the fastener on the truss by tightening the fastening bolt 4. When components of the fastener age or are damaged, the main body 2 of the fastener can be removed from the truss by removing the fastening bolt 4. The removal and repair of a single truss fastener will not affect other fasteners installed on the same layer of the truss. During the removal process, the fastening bolt 4 can be quickly removed without using any tools.

[0022] When the truss fastener in this application is in use, the fasteners between adjacent two layers of trusses need to be cross-installed. That is to say, such a setting can enable the recessed openings provided on the pressure-bearing member 1 to simultaneously bear the pressure generated by the upper layer of the truss, and can support the upper layer of the truss from being bent and deformed by the pressure; when it is necessary to fasten two layers of trusses simultaneously, the two fasteners can use the U-shaped bolt 5 to connect the two main bodies of the fasteners together through the holes provided at the right end of the main body 2. The two connected fasteners will not affect the repair and replacement when a subsequent single fastener is damaged.

[0023] In other specific applications of the detachable truss fastener in this application, the shape of the main body of the fastener, the shape of the pressure-bearing member, and the cross-sectional shape of the socket can be rectangular, rounded rectangular, diamond-shaped, pentagonal or other polygons. Of course, it can also be an irregular shape, and the size specifications of the three can be adjusted according to actual needs; the cross-sectional shape of the U-shaped bolt can also be adjusted according to actual needs. Of course, other connectors that can connect the two main bodies of the fastener together can also be selected; the length of the fastening bolt can also be set to 1.8 cm, 2 cm, 2.2 cm, 2.5 cm, 3 cm, etc., as long as it can effectively press the truss; the applicable range of the diameter of the truss for the socket can be adjusted according to actual needs, and will not be elaborated here one by one.

[0024] Finally, it should be noted that the above are only the preferred embodiments of the present utility model and are not used to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements on some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present utility model shall be included in the protection scope of the present utility model.
