[0017] In order to make the purpose, technical solution and advantages of the embodiments of the present utility model clearer, the technical solution of the present utility model will be clearly and completely described below in conjunction with the embodiments.

[0018] Example

[0019] like Figure 1 , Figure 2 As shown, Figure 1 The figure shows the overall schematic diagram of the steel structure truss in the embodiment. Figure 2 It is shown that Figure 1 A in the figure is an enlarged structural diagram.

[0020] The device includes a steel frame 11, an oblique brace 12 and a straight brace 13. The steel frames 11 are two parallel arranged. The oblique brace 12 and the straight brace 13 are detachably connected to the steel frame 11 through a connecting piece 20 and are arranged between the steel frames 11. A connecting piece 2 is provided at the end of the steel frame 11, and the connecting piece 2 can detachably connect multiple groups of steel frames 11.

[0021] The fast assembly of the diagonal brace 12, the straight brace 13 and the steel frame 11 is realized by providing the first connector 20, and the assembly between multiple groups of steel frames 11 is realized by providing the second connector.

[0022] like Figure 1 , Figure 2 As shown, Figure 1 The figure shows the overall schematic diagram of the steel structure truss in the embodiment. Figure 2 It shows Figure 1 A in the figure is an enlarged structural diagram.

[0023] The connecting piece 20 includes a connecting block 21, which is arranged at the two connecting ends of the diagonal support 12 and the straight support 13. The connecting block 21 is provided with a connecting hole that passes through the length direction of the steel frame 11. The steel frame 11 is provided with a connecting groove and a movable groove 22. The connecting groove corresponds to the position of the connecting block 21. The movable groove 22 is cross-connected with the connecting groove. A clamping block 23 and a spring 24 are movably arranged in the movable groove 22. The clamping block 23 can be movably inserted into the connecting hole of the connecting block 21. It also includes a gripping rod 25, which is fixedly connected to the clamping block 23, and one end of which extends out of the movable groove 22.

[0024] When installing the diagonal brace 12 or the straight brace 13, first hold the gripping rod 25 to move the clamping block 23 in the direction of the extrusion spring 24 until the clamping block 23 does not affect the connection block 21 from being inserted into the connection groove. After the connection block 21 at one end of the diagonal brace 12 or the straight brace 13 is successfully installed into the connection groove, release the gripping rod 25. The clamping block 23 moves toward the connection block 21 under the action of the restoring force of the spring 24 until it is inserted through the connection hole of the connection block 21. The clamping block 23 limits and fixes the connection block 21. Similarly, the connection block 21 at the other end of the diagonal brace 12 or the straight brace 13 is limited and fixed in turn.

[0025] By arranging the connection block 21, the clamping block 23 and the spring 24 to cooperate with each other, the assembly of the diagonal support 12 or the straight support 13 is simple and easy to operate, no other auxiliary tools are required, and the assembly is fast and efficient.

[0026] The second connector includes a connecting plate 30 disposed at the end of each steel frame 11 . The connecting plate 30 is provided with at least two plug holes 31 . The plug holes 31 of adjacent steel frames 11 are aligned and movably inserted into the connector 32 .

[0027] The plug-in connector 32 refers to a component that can be used to lock and connect adjacent steel frames 11 through the reserved and aligned plug-in holes 31, such as bolts and nuts, pins, etc. The connector is assembled between two pairs of segmented steel frames 11.

[0028] Working principle: When assembling the device, first install the diagonal brace 12 or the straight brace 13 between the relatively arranged steel frames 11 through the connector 1 20. The assembly principle is as follows: first, hold the grip 25 to move the clamping block 23 at the assembly position toward the direction of the extrusion spring 24 until the clamping block 23 does not affect the connection block 21 from being inserted into the connection groove. After the connection block 21 at one end of the diagonal brace 12 or the straight brace 13 is successfully installed into the connection groove, release the grip 25. Under the action of the restoring force of the spring 24, the clamping block 23 moves toward the connection block 21 until it is inserted through the connection hole of the connection block 21. The clamping block 23 limits and fixes the connection block 21. Similarly, the connection block 21 at the other end of the diagonal brace 12 or the straight brace 13 can be limited and fixed in turn. After the diagonal brace 12 or the straight brace 13 is assembled, multiple segmented steel frames 11 are assembled through the connector 2, that is, the plug holes 31 of the adjacent steel frames 11 are aligned and movably inserted into the connector 32.

[0029] The above embodiments are only used to illustrate the technical solution of the present invention, but not to limit it.
