The disclosure may be embodied or practiced in other different specific embodiments, and details within the subject specification may be modified or changed from various points of view and applications without departing from the spirit of the disclosure. It should be noted that the following embodiments and features in the embodiments may be combined with each other without conflict. All other embodiments, which can be made by one of ordinary skill in the art without inventive effort, based on the embodiments in this disclosure are intended to be within the scope of this disclosure.

Example 1

An environment-friendly assembled steel structure is shown in figures 1-2 and 5 and comprises a cross beam 1 and a stand column 2, wherein the cross beam 1 is connected with the stand column 2. The side of the upright post 2 is provided with a through hole 21, and four first plates 22 are arranged on the inner side of the through hole 21. Channels 23 are formed by the inner sides of four of said first panels 22. An annular groove 11 is formed in the outer wall of the cross beam 1, and two second plates 12 and two third plates 13 are mounted on the inner side of the annular groove 11. Second plate 12 is mounted on both sides of annular groove 11 and third plate 13 is mounted on the other both sides of annular groove 11.

Further, the first plate 22, the second plate 12 and the third plate 13 are all made of wood material. Can be a solid wood board, a solid wood composite board, a joinery board, a plywood, a large core board, a finger joint board and the like.

Further, the cross beam 1 is mounted inside the channel 23. The second plate 12 and the third plate 13 are fixed to the first plate 22 by bolts. The bolts are used here only for the first plate 22 to fix the second plate 12 and the third plate 13 without damaging the steel structure.

Further, as shown in fig. 3-4, four sets of clamping grooves 211 are formed on the outer side of the through hole 21, and each set of clamping grooves 211 corresponds to one side edge of the through hole 21. Further, a set of clamping blocks 221 is disposed on the outer side of each first plate 22, and the clamping blocks 221 are mounted on the outer side of the first plate 22 in a bolt fixing or clamping manner. The surface of the first plate 22 is provided with a lacquering layer 222, and the lacquering layer 222 protects the surface of the first plate 22. Further, the shape and size of the clamping groove 211 are the same as those of the clamping block 221, and the positions of the clamping groove and the clamping block correspond to each other. The locking groove 211 and the locking block 221 have the function of limiting the movement of the first plate 22.

Further, the inner side of the channel 23 is a rough surface. The roughened surface serves to increase friction and to facilitate the fixing of the second plate 12 and the third plate 13.

Further, at least eight sets of bumps 111 are provided on the inner side of the annular groove 11. Each set of protruding blocks 111 corresponds to the lateral sides of the two sides of the annular groove 11, so as to be beneficial to clamping and extrusion with the lateral sides of the second plate 12 and the third plate 13.

Further, the maximum outer diameter of the cross beam 1 is smaller than the maximum inner diameter of the channel 23, so that the cross beam 1 can move inside the channel 23 during the installation process.

Further, the sides of the second plate 12 and the third plate 13 are at the same level as the sides of the cross beam 1. The purpose is to not change the maximum outer diameter of the transverse beam 1 after the installation of the second plate 12 and said third plate 13.

The working principle is as follows:

in the mounting, first plate 22 is first mounted inside through hole 21 by engaging with engaging groove 211 and engaging groove 221. In the second step, two second plates 12 are press-fitted to both sides of the annular groove 11. Two of the third plates 13 are press-fitted to the other two sides of the annular groove 11. Care was taken during pressing to press the second plate 12 and the third plate 13 to the bottom of the annular groove 11. Beam 1 is then extended into the interior of channel 23, second plate 12 and third plate 13 on beam 1 are brought into register with first plate 22, and finally first plate 22 and second plate 12 are secured to each other by bolts, and first plate 22 and third plate 13 are secured to each other.
