Referring to fig. 1-5, the present invention provides a technical solution:

A butterfly truss for a building structure is disclosed, as shown in fig. 1 to fig. 3, comprising a plurality of fixing plates 1 arranged in parallel downward, each fixing plate 1 comprises two strip-shaped plates 11 parallel to each other, and the two strip-shaped plates 11 are located on the same horizontal plane, one end of each strip-shaped plate 11 is provided with a first connecting body 12, the other end of each strip-shaped plate 11 is provided with a second connecting body 13, each first connecting body 12 is provided with two first connecting rods 121 parallel to each other, each second connecting body 13 is provided with two second connecting rods 131 parallel to each other, a plurality of butterfly pieces 14 distributed linearly at equal intervals are arranged between the two first connecting bodies 12 parallel to each other and the two second connecting bodies 13 parallel to each other, an end of each butterfly piece 14 is provided with a screw 141, the screw 141 located at one end of the butterfly pieces 14 passes through a gap between the two second connecting rods 131 parallel to each other and is connected with the two butterfly pieces in a sliding manner, the screw 141 at the other end of the butterfly piece 14 passes through the gap between the two parallel first connecting rods 121 and is slidably connected with the same, the bottom end of each screw 141 is provided with a limit nut 142, and the end of each first connecting body 12 and the end of each second connecting body 13 are fixedly connected with a connecting plate 15.

it should be noted that the sliding connection between the screw 141 and the first and second links 121 and 131 is a relatively tight connection, and the butterfly plate 14 can slide between the first and second links 121 and 131 only under the external force.

In this embodiment, each first connecting body 12 and each second connecting body 13 respectively penetrate through two ends of the strip-shaped plate 11, and the strip-shaped plate 11 is tightly welded with the first connecting body 12 and the second connecting body 13 respectively. The adjusting mechanism 2 between the two strip-shaped plates 11 is used for adjusting the horizontal height of the butterfly truss, and the stability and the feasibility of the adjusting mechanism 2 are ensured by the connection mode of tight welding.

As shown in fig. 4 and 5, an adjusting mechanism 2 is arranged between the two strip-shaped plates 11, the adjusting mechanism 2 includes two movable blocks 21 parallel to each other from top to bottom and two fixed blocks 22 parallel to each other from left to right, two movable plates 23 are symmetrically arranged on the movable blocks 21, a threaded hole 211 is formed in the movable block 21 below, a threaded rod 3 is arranged between each of the adjusting mechanisms 2, the threaded rod 3 penetrates through the threaded hole 211, and the end of the threaded rod 3 is rotatably connected with the movable block 21 above through a bearing.
