At the same time, the risk of the fixing piece falling off from the surface of the heterogeneous steel structure body is reduced, the stability of the connection of the heterogeneous steel structure body is improved, and the PVC fiber layer effectively improves the heat insulation and sound insulation effects of the heterogeneous steel structure body.

[0004] However, the utility model steel structure has good heat insulation and sound insulation effects, but cannot achieve the function of adjusting the time distance between two steel structures, resulting in the need to purchase more steel components for connection. Therefore, a steel structure for construction is proposed to solve the above problems. Utility Model Content

[0005] In view of the deficiencies in the prior art, the utility model provides a steel structural member for construction, which has advantages such as spacing adjustment, and solves the problem that the time spacing adjustment between two steel structural members cannot be achieved, resulting in the need to purchase more steel components for connection.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a steel structure for construction, comprising two square steels, positioning devices are arranged on opposite sides of the two square steels, and a fixing piece is arranged between the two square steels;

[0007] The fixing part includes a protective cylinder fitted between the two square steels, a rotating shaft rotatably sleeved on the left side of the protective cylinder, a first bevel gear sleeved on the rotating shaft at one end close to the protective cylinder, a second bevel gear meshingly connected to the lower side of the first bevel gear, a threaded cylinder sleeved on the inner wall of the second bevel gear, two threaded rods threadedly connected to the inner wall of the threaded cylinder, a limiting plate sleeved on the outer side of the threaded rod close to one side of the threaded cylinder, a mounting plate fixedly connected to the side of the threaded rod away from the threaded cylinder, and a latch integrally connected to the mounting plate at one end away from the threaded rod.

[0008] Furthermore, the positioning device includes two telescopic connection limit plates sleeved on the side surfaces of the square steel and a connecting piece threadedly connected to one end of the telescopic connection limit plates close to the square steel.

[0009] Furthermore, the threaded barrel is a bidirectional threaded barrel, and two positioning rings are sleeved on the outer side of the threaded barrel.

[0010] Furthermore, the side of the positioning collar away from the threaded barrel is vertically connected to the inner wall surface of the protection barrel, and the positioning collar includes a bearing and a bearing seat.

[0011] Furthermore, two positioning holes are provided inside the mounting plate, and the latch penetrates the square steel and extends to the outside.

[0012] Furthermore, a handle is sleeved on one side of the rotating shaft away from the first bevel gear, and two sliding blocks are fixedly connected to the side surface of the limiting plate.

[0013] Furthermore, a sliding groove matched with the sliding block is formed on the inner wall of the protection tube, and the sliding block is slidably connected in the sliding groove.

[0014] Compared with the prior art, the utility model provides a steel structure for construction, which has the following beneficial effects:

[0015] 1. The steel structure for building is connected to the fixing member through the connecting member and the telescopic connecting limit plate, and then the adjustment of the mounting plate is realized through the first bevel gear and the second bevel gear, and the two square steels are pushed to move relative to or away from each other to achieve the effect of adjusting the spacing.

[0016] 2. The steel structural parts of the building are fixed to the outside of the threaded rod through the limit plate to limit the position. At the same time, they can also isolate the external water vapor from entering the protective tube, achieving a barrier effect. This solves the problem of being unable to adjust the time distance between the two steel structural parts, which requires the purchase of more steel components for connection.

[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] See also Figures 1 to 4 In this embodiment, a steel structural member for construction includes two square steels 1, a positioning device is provided on one side opposite to the other of the two square steels 1, and a fixing member is provided between the two square steels 1. The fixing member includes a protective tube 5 fitted between the two square steels 1, a rotating shaft 12 rotatably sleeved on the left side of the protective tube 5, a first bevel gear 6 sleeved on the rotating shaft 12 near one end of the protective tube 5, a second bevel gear 7 meshingly connected to the lower side of the first bevel gear 6, a threaded tube 8 sleeved on the inner wall of the second bevel gear 7, two threaded rods 9 threadedly connected to the inner wall of the threaded tube 8, a limiting plate 10 sleeved on the outer side of the threaded rod 9 near one side of the threaded tube 8, a mounting plate 4 fixedly connected to the side of the threaded rod 9 away from the threaded tube 8, and a latch 13 integrally connected to the end of the mounting plate 4 away from the threaded rod 9.

[0024] Among them, the positioning device includes two telescopic connection limit plates 3 sleeved on the side surfaces of the square steel 1 and a connecting piece 2 threadedly connected to the telescopic connection limit plates 3 near one end of the square steel 1. The threaded tube 8 is a bidirectional threaded tube. Two positioning collars 11 are sleeved on the outer side of the threaded tube 8. The side of the positioning collar 11 away from the threaded tube 8 is vertically connected to the inner wall surface of the protective tube 5. The positioning collar 11 includes a bearing and a bearing seat. Two positioning holes are opened inside the mounting plate 4. The pin 13 passes through the square steel 1 and extends to the outside. A handle is sleeved on the side of the rotating shaft 12 away from the first bevel gear 6. Two sliders are fixedly connected to the side surface of the limit plate 10. The inner wall of the protective tube 5 is opened with a slide groove matching the slide. The slide is slidably connected in the slide groove.

[0025] It should be noted that the inner wall of the protective tube 5 is coated with waterproof paint, which, together with the limit plate 10, can effectively isolate water vapor from entering the protective tube 5 and reduce the erosion of internal parts. The outer side of the limit plate 10 is coated with a rubber layer, which has good barrier and sealing properties. When the threaded rod 9 pushes the mounting plate 4 to move, the two sides of the limit plate 10 slide in the slide groove through the sliders to limit the mounting plate 4.

[0026] The working principle of the above embodiment is:

[0027] The protective tube 5 is placed between the two square steels 1, and the pin 13 on the surface of the mounting plate 4 outside the protective tube 5 is aligned with the through hole opened in the side of the square steel 1 for plugging and fixing, and the positioning hole inside the mounting plate 4 is aligned with the through hole without the plug pin 13, and the telescopic connection limit plate 3 is taken out and sleeved on the positioning hole and the upper side of the through hole, and the connecting piece 2 is pressed against the surface of the telescopic connection limit plate 3, and the square steel 1, the connecting piece 2, the telescopic connection limit plate 3 and the mounting plate 4 are fixed by bolts. When adjusting the spacing between the two square steels 1, the first bevel gear 6 on the outside of the rotating shaft 12 is rotated to engage the second bevel gear 7, so that the threaded tube 8 drives the threaded rod 9 to drive and push the connected mounting plate 4 to move relative or opposite to each other, so as to adjust the spacing between the two square steels 1. During the movement of the square steel 1, the telescopic connection limit plate 3 will also extend its own length to achieve the effect of firm support.
