[0002] A building construction truss is a supporting beam structure made of rods connected by welding, riveting or bolting. These rods are connected by hinges at both ends, usually forming a plane or space structure with triangular units. The truss is composed of straight rods, in which the vertical rods are perpendicular to the ground, the horizontal rods are placed horizontally, and the diagonal rods connect the vertical rods and the horizontal rods to form a stable triangular structure.

[0003] When installing the trusses at the top of the building, the two large trusses are first hoisted to the top of the support rod using lifting equipment. After the top of the trusses are welded to the support rod, high-strength bolts are used to connect the secondary beams at the upper and lower chords between the two trusses. When welding the two trusses, it is necessary to ensure that the angles between the trusses and the support rods are the same. When connecting the secondary beams, if there is a certain deviation in the angle between the two trusses, it will make it difficult to insert the bolts at the connection between the two ends of the secondary beam and the truss when installing, affecting the normal installation of the truss.

By setting the pressing block 214 and the pressing rod 28, when the frame 1 is hoisted on the top of the support rod for welding, a specified number of T-shaped blocks 22 can be inserted into the T-shaped slot 21 at one end of the frame 1, so that the T-shaped block 22 is located inside the T-shaped slot 21 and one side of the rectangular block 23 is attached to one side of the frame 1. Pushing the cylinder 24 can control the T-shaped block 22 to slide on the inner wall of the T-shaped slot 21 to adjust the horizontal position of the cylinder 24, and then rotating the first screw 210 The first screw 210 is controlled to rotate on the inner wall of the threaded cylinder 29, driving the round rod 26 to slide on the inner wall of the rectangular groove 25 through the two rectangular rods 27 and move in the direction away from the cylinder 24, so that one side of the pressure rod 28 is pressed against the surface of the other frame 1 and the position of the pressure rod 28 is fixed, and then a ring 213 on the inner wall of a pressure block 214 is put on the outer surface of the second screw 211, and the positioning rod 215 at the bottom end of the pressure block 214 is fitted on the bottom end of the pressure rod 28, and the pressure block 214 is held by hand and the threaded ring 212 is rotated, so that the threaded ring 212 rotates on the inner wall of the ring 213 and is fixed on the second screw The outer surface of 211 moves, and the positioning rod 215 at the bottom of the pressure block 214 slides at the bottom of the pressure rod 28, and the moving pressure block 214 presses one side of the pressure block 214 against the other side of the outer surface of the frame 1 close to the pressure rod 28. The frame 1 is clamped by the pressure block 214 and the pressure rod 28, and the angle between the frame 1 with the positioning device 2 on the outer surface and another frame 1 away from the frame 1 is restricted, so as to ensure that the angles of the two frames 1 are kept uniform during welding and installation, and to avoid the angle of the frame 1 from being skewed as much as possible, which affects the installation of subsequent structures such as secondary beams.

[0044] Reference Figure 2-7As shown, this embodiment discloses that the inner wall of the pressure rod 28 is slidably connected with a sliding rod 218, and the top of the sliding rod 218 is fixedly connected with a positioning frame 216. The end of the positioning frame 216 away from the sliding rod 218 is made of rubber material. Before using the positioning device 2, pull the positioning frame 216 to make the sliding rod 218 slide upward on the inner wall of the pressure rod 28 to adjust the height position of the positioning frame 216 to avoid affecting the pressure rod 28 to fit on the surface of the frame 1, and clamp the pressure block 214 and the pressure rod 28 on the frame 1. After the outer surface is on both sides, the sliding rod 218 can be pushed to control the sliding rod 218 to move downward on the inner wall of the pressure rod 28 to adjust the height position of the positioning frame 216, and then the rubber material part of the positioning frame 216 is pulled to deform the positioning frame 216 and sleeve it on the outer surface of the pressure block 214, tightening the pressure block 214 and the top of the pressure rod 28, further fixing the angle and relative position between the pressure block 214 and the pressure rod 28, and increasing the stability of the fixed position of the pressure rod 28, the pressure block 214 and the frame 1.

A push rod 221 is fixedly connected to one side of the threaded ring 212, and one side of the push rod 221 rotates on one side of the pressing block 214. When holding the pressing block 214, the threaded ring 212 can be controlled to rotate by pushing the push rod 221, so that the threaded ring 212 can be more conveniently controlled to move on the surface of the second screw rod 211 to adjust the position of the pressing block 214.
