[0002] Steel structure building is a new type of building system, breaking through the industry boundaries between real estate, construction and metallurgical industries, integrating them into a new industrial system. Compared with traditional concrete buildings, steel structure buildings use steel plates or steel sections instead of reinforced concrete, which have higher strength and better earthquake resistance. In addition, since the components can be manufactured in factories and installed on site, the construction period is greatly reduced. Due to the reusability of steel, it can greatly reduce construction waste and is more environmentally friendly. Therefore, it is widely used in industrial and civil buildings.

[0003] In the prior art, connecting components are required when connecting beams and columns. Currently, most of the connecting components on the market are fixed steel structures. Due to construction and actual requirements, there are differences in the distances between beams and columns, and the connection length of the connecting components cannot be expanded and adjusted. Construction workers need to weld and produce them on site, which is time-consuming and labor-intensive.

[0004] The above information disclosed in the background technology is only used to increase the understanding of the background technology of the present application, and therefore, it may include information that does not constitute the prior art known to ordinary technicians in the field.

DETAILED DESCRIPTION

[0020] The following is combined with Figure 1-4 This application is described in further detail.

[0021] The present application embodiment discloses a building connecting steel member. Figure 1 , Figure 2 and Figure 3 A building connecting steel member, a steel frame 1 having a limited slot 7 on one side thereof, a fixed plate 8 fixedly connected to the limited slot 7 on both sides thereof, and the two fixed plates 8 are symmetrically distributed with the steel frame 1, two threaded rods 6 are rotatably connected to the steel frame 1 through the two fixed plates 8, two connecting rods 2 are lifted and connected to the steel frame 1 through the two threaded rods 6, and a limited block 12 is fixedly connected to the outer wall of the connecting rod 2 through both sides thereof, and a plurality of the limited blocks 12 are symmetrically distributed with the steel frame 1, and the two threaded rods 6 are symmetrically distributed with the steel frame 1. A second bevel gear 11 is fixedly connected to one side of the pair, and the size of the limit groove 7 is adapted to the size of the connector between the connecting rod 2 and the two limit blocks 12. The threaded rod 6 is connected to the connecting rod 2, and the fixed plate 8 is connected to the threaded rod 6, so that the threaded rod 6 can rotate inside the steel frame 1. The threaded rod 6 can rotate forward or reverse, and the moving direction of the connecting rod 2 can be limited by the two limit blocks 12, which can then drive the connecting rod 2 to rise or fall along the inner wall of the limit groove 7, thereby achieving the effect of adjusting the position of the threaded rod 6.

[0022] Reference Figure 2 and Figure 3 , inside the steel frame 1, a rotating rod 10 is rotatably connected at its center position, and a first bevel gear 9 is fixedly connected to one side of the rotating rod 10, and the first bevel gear 9 and the two second bevel gears 11 are tightly meshed. A sliding opening 17 is opened on the side surface of the first bevel gear 9 through one side thereof, and mounting grooves 18 are opened on the side surface of the first bevel gear 9 through the corresponding sliding openings 17 on both sides, and the first bevel gear 9 is tightly meshed with the two second bevel gears 11, and is connected to the threaded rod 6 through the second bevel gear 11, so that the rotation of the first bevel gear 9 drives the two second bevel gears 11 to rotate simultaneously, and then drives the two connecting rods 2 to move along the inner wall of the limiting groove 7, and by moving the two connecting rods 2 away from each other, the connection length of the steel frame 1 is expanded and adjusted, thereby achieving the effect of adjusting the length of the steel frame 1.

[0023] Reference Figure 2 and Figure 4 A cavity 19 is opened in one side of the rotating rod 10, and a spring 15 is fixedly connected to the rotating rod 10 through one side thereof. A pull rod 16 is slidably connected to the rotating rod 10 in the steel frame 1, and a partition 14 is fixedly connected to the outer wall of the pull rod 16 through one side thereof. The pull rod 16 is moved along the inner wall of the rotating rod 10 by pulling the pull rod 16, and the size of the partition 14 is matched with the size of the cavity 19. The spring 15 is used to connect to one side of the inner wall of the rotating rod 10, and the partition 14 is squeezed close to the inner wall of the rotating rod 10 by the spring 15, so that the pull rod 16 is limited, so that the pull rod 16 is separated from the first bevel gear 9, so as to avoid accidental touching of the pull rod 16 to drive the first bevel gear 9 to rotate, thereby achieving the effect of avoiding accidental rotation of the first bevel gear 9.

[0024] Reference Figure 4 On the outer wall of the pull rod 16, mounting blocks 13 are fixedly connected on both sides thereof, and the two mounting blocks 13 are symmetrically distributed with the pull rod 16, and the sizes of the mounting blocks 13 are adapted to the sizes of the mounting grooves 18. A knob 3 is fixedly connected to one side of the pull rod 16, and the pull rod 16 is moved along the inner wall of the rotating rod 10 by pulling the pull rod 16. With the continuous movement of the pull rod 16, the two mounting blocks 13 on the pull rod 16 enter the mounting groove 18 on the outer wall of the first bevel gear 9, and then the pull rod 16 is installed and connected with the first bevel gear 9, and the pull rod 16 is connected with the knob 3 through the pull rod 16, so that the first bevel gear 9 is rotated by rotating the knob 3, and the first bevel gear 9 is connected with the rotating rod 10 through the first bevel gear 9, so that the first bevel gear 9 and the rotating rod 10 are rotated at the same time, and the first bevel gear 9 is tightly meshed with the two second bevel gears 11, and then the two second bevel gears 11 are driven to rotate at the same time, thereby achieving the effect of facilitating the two second bevel gears 11 to rotate at the same time.

[0025] Reference Figure 1 , Figure 2 and Figure 3 The two connecting rods 2 are fixedly connected to a positioning bracket 4 on the opposite side. On the outer surface of the positioning bracket 4, fixing holes 5 are opened on both sides, and several fixing holes 5 are symmetrically distributed with the steel frame 1. The steel frame 1 is connected and fixed to the external beam frame through several fixing holes 5 on the two positioning brackets 4.

[0026] The implementation principle of a building connection steel member in the embodiment of the present application is as follows: first, according to the length of the beam-column spacing, the pull rod 16 is pulled to move along the inner wall of the rotating rod 10. As the pull rod 16 continues to move, the two mounting blocks 13 on the pull rod 16 enter the mounting groove 18 on the outer wall of the first bevel gear 9, and then the pull rod 16 is installed and connected with the first bevel gear 9, and the pull rod 16 is connected with the knob 3, so that the first bevel gear 9 is rotated by turning the knob 3, and the first bevel gear 9 is connected with the rotating rod 10, so that The first bevel gear 9 and the rotating rod 10 rotate simultaneously, and the first bevel gear 9 is tightly meshed with the two second bevel gears 11, which then drives the two second bevel gears 11 to rotate simultaneously, and is connected to the threaded rod 6 through the second bevel gear 11. The threaded rod 6 rotates forward or reversely, and the moving direction of the connecting rod 2 is limited by two limit blocks 12, which then drives the connecting rod 2 to rise or fall along the inner wall of the limit groove 7. The threaded rod 6 rotates to make the two connecting rods 2 move away from each other, so that the connection length of the steel frame 1 is expanded and adjusted.
