[0003] The combined corridor is composed of several single corridors continuously assembled. In the specific assembly process, the ports of the corridors are aligned, and then bolts are passed through the skeletons of the corridor ports for tensioning and fixing. A number of bolts need to be fixed around the circumference of the corridor port. The workload of fixing the bolts is large, and during the assembly process, the reserved holes of several bolts need to be aligned, and the alignment accuracy of the corridor needs to be finely adjusted, so the assembly operation is difficult. Summary of the Invention

[0005] In order to solve the existing technology problems, the technical solution of the present invention is as follows:

[0006] A modular steel structure corridor includes: a corridor box body. The port of the corridor box body has a square frame. The center positions of the end faces of both sides of the frame have positioning holes. It also includes two symmetrically distributed arm rods. A tensioning screw rod is fixed in the middle of the arm rod. The tensioning screw rod is inserted into the positioning hole to align the frame. A plurality of nail columns are arranged and fixed on the upper and lower parts of the end faces of both sides of the frame. The end of the nail column has an enlarged diameter cap. Nuts are tightened at both ends of the tensioning screw rod to make the frame close. The enlarged diameter caps of the nail columns are in contact. The top of the arm rod inclines outward from the frame and the bottom inclines inward from the frame. The side of the arm rod has a concave cavity. The edge of the concave cavity is provided with a plurality of buckling grooves for aligning the nail columns. The top of the arm rod is laterally tensioned and connected to the frame through an extended bolt, so that the arm rod rotates to a vertical state with the tensioning screw rod as the center, and the nail columns are correspondingly clamped into the buckling grooves, and the enlarged diameter caps are clamped into the concave cavity.

[0007] Preferably, chamfers are provided on the edge of the enlarged diameter cap and the inner edge of the buckling groove.

[0009] Preferably, the buckling groove is V-shaped, and the top part of the V shape is an arc contour adapted to the nail column.

[0010] Preferably, panels are fixed to the top outer side and the bottom inner side of the arm. When the arm is rotated to a vertical state, the panels are flat against the side of the frame. The panels are fixed to the side of the frame by screws. The top panel surface has strip holes, and the extended bolts pass through the strip holes and are connected to the frame laterally.

[0011] Preferably, both sides of the panel are bent to form edges, and when the panel is flat against the frame, the edges are clamped on opposite sides of the two frames.

The two sides of the top gusset plate have upward right-angled edges, and the two sides of the bottom gusset plate have downward right-angled edges. The right-angled edges of the top gusset plate and the bottom gusset plate are both stuck on the opposite sides of the two frames.

[0013] Preferably, the surfaces of the top gusset plate and the bottom gusset plate both have concave stamping portions, and the concave stamping portions are adapted to be inserted between the two frames.

[0036] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments.

[0037] As Figure 1-2 shown, each monomer of the modular steel structure corridor has a corridor box body, and the structure of the corridor box body is the same as that of the existing box-type corridor. A square frame 1 is fixedly welded to the port of the corridor box body, and the frame 1 is formed by welding four hollow square steel materials.

[0038] Positioning holes 41 are opened at the central positions of the end faces on both sides of the frame 1, and the positioning holes 41 penetrate through the frame 1. A plurality of studs 2 are fixedly arranged at the upper and lower parts of the end faces on both sides of the frame 1 respectively. The studs 2 are cylindrical, and the ends of the studs 2 have enlarged diameter caps.

[0039] As Figure 2-8 shown, there are two arms 3. A tie rod 4 is fixedly penetrated through the center position of the arm 3, and the tie rod 4 extends the same length on both sides of the arm 3. Cavities 61 are opened on one side of the upper part and the other side of the lower part of the arm 3. The width of the cavity 61 is uniform, and the width of the cavity 61 is twice the thickness of the enlarged diameter cap. A plurality of buckle grooves 6 are arranged along the edge of the cavity 61. The distribution positions of the buckle grooves 6 are the same as the distribution positions of the studs 2, and the buckle grooves 6 are V-shaped, and the top part of the V shape is an arc-shaped contour adapted to the stud 2.

[0040] Panels 31 are fixedly welded to one side of the top of the arm 3 facing away from the cavity 61 and one side of the bottom of the arm 3 facing away from the cavity 61. Assembly holes are symmetrically opened on the surface of the panel 31, and a vertically extending slot 32 is provided on the surface of the top panel 31.

[0041] The combined assembly operation of the corridor is as follows:

[0042] As Figure 3-6As shown, the corridor boxes are arranged end to end, the frames 1 at adjacent corridor openings are aligned, the two arm rods 3 are placed on both sides between the two frames 1, the tie rods 4 on the surface of the arm rod 3 are inserted into the positioning holes 41 on the surface of one of the frames 1, and nuts are used to threadedly fasten the tie rods 4, so that the arm rod 3 is flat against the surface of this frame 1, but the arm rod 3 needs to be kept rotatable. Then, lift or move another corridor box, and the positioning hole 41 of the port frame 1 of this corridor box is inserted into the other end of the tie rod 4. The two groups of tie rods 4 and the two positioning holes 41 are linearly inserted to keep the two frames 1 linearly aligned. The top of the arm rod 3 is inclined outward from the frame 1, and the bottom is inclined inward from the frame 1. Nuts are used to fasten the tie rods 4 to pull the two frames 1 closer, and the nail posts 2 on the surfaces of the two frames 1 are linearly aligned until the enlarged diameter caps at the ends of the nail posts 2 are in contact with each other;

[0043] The lengthened bolts 5 pass through the strip holes 32 and are connected to the side of the frame 1. Tightening the lengthened bolts 5 pushes the arm rod 3 to rotate around the tie rod 4, so that the arm rod 3 rotates to the vertical state. At this time, the buckle grooves 6 are correspondingly stuck on the outside of the nail posts 2, and the enlarged diameter caps are all stuck into the concave cavities 61. Since the width of the concave cavity 61 is twice the thickness of the enlarged diameter cap, the flat enlarged diameter cap is clamped by the concave cavity 61 to lock the distance between the frames 1. The top panel 31 is flat against the outer surfaces of the two frames 1, and the bottom panel 31 is flat against the inner surfaces of the two frames 1. Screws are used to pass through the assembly holes on the surface of the panel 31 and are fixedly connected to the frame 1. Finally, the nuts at both ends of the tie rod 4 are tightened to fix the angle of the arm rod 3.

[0044] As Figure 8 shown, chamfers are provided on the edges of the enlarged diameter caps and the inner edges of the buckle grooves 6. During the rotation of the arm rod 3, it is pushed by the inclined surface of the chamfer, so that the enlarged diameter cap can be smoothly stuck into the concave cavity 61, which has the function of automatically tightening and aligning the nail posts 2.

[0045] As Figure 9-10 shown, the edges on both sides of the panel 31 are bent to form flanges, and the inner ends of the flanges have chamfers. When the arm rod 3 is rotated to drive the panel 31 to be flat against the frame 1, the flanges of the panel 31 are stuck on the opposite sides of the two frames 1 through the guidance of the chamfers, further locking the distance between the two frames 1. There are panels 31 at the four corners of the frame 1, and there is a clamping effect in the four-corner areas of the two frames 1, improving the assembly stability.

[0046] The two side edges of the two frames 1 are supported by the arm rod 3. After the assembly is completed, there are gaps between the top edges and the bottom edges of the two frames 1. To improve the connection strength of the top and bottom of the frame 1, top buckles 7 and bottom buckles 8 are respectively arranged at the top and bottom inside the frame 1;

[0047] As Figure 9-12As shown, both ends of the top buckling plate 7 have horizontal folding ears. The folding ears of the top buckling plate 7 are flat against the top of the arm rod 3 and are fixed with screws. Both sides of the top buckling plate 7 have upward right-angle folding edges, and the right-angle folding edges are stuck on the opposite sides of the top edges of the two frames 1. The surface of the top buckling plate 7 has concave stamping parts, and the concave stamping parts are adaptively clamped between the top edges of the two frames 1. Through the outer wrapping of the right-angle folding edges and the inner support of the concave stamping parts, the connection gap between the top edges of the two frames 1 is maintained, and the connection stability of the two frames 1 is improved.

[0048] Both ends of the bottom buckling plate 8 have vertical folding ears. The folding ears of the bottom buckling plate 8 are flat against the panel 31 at the bottom of the arm rod 3 and are fixed with screws. Both sides of the bottom buckling plate 8 have downward right-angle folding edges, and the right-angle folding edges are stuck on the opposite sides of the bottom edges of the two frames 1. The surface of the bottom buckling plate 8 has concave stamping parts, and the concave stamping parts are adaptively clamped between the bottom edges of the two frames 1. Through the outer wrapping of the right-angle folding edges and the inner support of the concave stamping parts, the connection gap between the bottom edges of the two frames 1 is maintained, and the connection stability of the two frames 1 is improved.

[0049] Both ends of the top buckling plate 7 are connected to the top ends of the arm rod 3, and both ends of the bottom buckling plate 8 are connected to the bottom ends of the arm rod 3, further fixing the shape of the arm rod 3, generating mutual restraint forces between the entire assembly structures, and making the corridor combined assembly more stable.

[0050] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of the present invention.
