Description

Technical Field

[0001] The present invention relates to the field of corridors, and in particular to a modular steel structure corridor and a combined assembly method. Background Art

[0002] In each production link of a large outdoor industrial production line, corridors are used to connect each production link in series for enclosed material transportation. According to the distribution of specific production points and the terrain, the extension path of the corridor is set. To simplify the construction work of the corridor of the production line, a combined corridor is used for on-site assembly.

[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 used to penetrate the skeletons of the corridor ports for tensioning and fixing. A number of bolts need to be fixed around the perimeter 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

[0004] In order to make up for the deficiencies of the existing technology problems, the purpose of the present invention is to provide a modular steel structure corridor and a combined assembly method, which are used to solve the problems of high operation difficulty in aligning and adjusting the corridor ports and large workload of bolt fixing when the traditional corridor is fixed by bolts in a circumferential manner.

[0005] In order to solve the existing technology problems, the technical solution of the present invention is as follows: A modular steel structure corridor includes: a corridor box body. The port of the corridor box body has a square frame. At the central positions of the end faces of both sides of the frame, there are positioning holes. It also includes two symmetrically distributed arm rods. A tensioning screw is fixed in the middle of the arm rod. The tensioning screw 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 to make the frame approach. The enlarged diameter caps of the nail columns are in contact with each other. The top of the arm rod inclines outward from the frame, and the bottom inclines inward from the frame. There is a concave cavity on the side of the arm rod. A plurality of buckling grooves for positioning the nail columns are arranged at the edge of the concave cavity. 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 as the center, and the nail column is correspondingly clamped into the buckling groove, and the enlarged diameter cap is clamped into the concave cavity.

[0006] Preferably, chamfers are provided at the edges of the enlarged diameter cap and the inner edge of the buckling groove.

[0007] Preferably, the flat contact thickness of the two enlarged diameter caps is the same as the width of the concave cavity.

[0008] Preferably, the buckling groove is V-shaped, and the top part of the V shape is an arc profile adapted to the nail column.

[0009] Preferably, panels are fixed to the outer side of the top and the inner side of the bottom of the arm. When the arm rotates to the vertical state, the panels are flat against the side surface of the frame. The panels are fixed to the side surface of the frame by screws. The surface of the panel at the top has slotted holes, and the lengthened bolts pass through the slotted holes and are laterally connected to the frame.

[0010] Preferably, the two sides of the panel are bent to form edge wraps. When the panel is flat against the frame, the edge wraps are stuck on the opposite sides of the two frames.

[0011] Preferably, top buckles and bottom buckles are respectively arranged at the top and the bottom inside the frame. The two ends of the top buckle and the bottom buckle are respectively connected to the top and the bottom of the two arms by screws. The two sides of the top buckle have upward right-angle flanges, and the two sides of the bottom buckle have downward right-angle flanges. The right-angle flanges of the top buckle and the bottom buckle are both stuck on the opposite sides of the two frames.

[0012] Preferably, the surfaces of the top buckle and the bottom buckle both have concave stamping parts, and the concave stamping parts are adapted to be snapped into the space between the two frames.

[0013] The combined assembly method of the modular steel structure corridor is as follows: A. Align and insert the two arms into the positioning holes on the surface of one of the frames through the tension bolts, fasten the tension bolts with nuts, and keep the arms rotatable; B. Insert the tension bolts into the positioning holes on the surface of the other frame to align the two frames in a straight line, fasten the tension bolts with nuts, tighten the two frames together, and make the nail columns abut against each other; C. Lateral tension the top end of the arm and the frame through the lengthened bolts, make the arm rotate around the tension bolt as the center. When the arm rotates to the vertical state, make the nail columns snap into the buckle grooves one by one, and the expanded diameter caps snap into the concave cavities. Lock the positions of the two frames by the side surfaces of each expanded diameter cap abutting against the concave cavities; D. Tighten the nuts at both ends of the tension bolt again to lock the angle of the arm.

[0014] Compared with the prior art, the advantages of the present invention are as follows: 1. In the present invention, the positions of the two frames and the arms are accurately aligned by inserting two groups of tension bolts into the positioning holes. By laterally tightening the lengthened bolts, the arm rotates around the tension bolt as the center, automatically making all the nail columns snap into the buckle grooves and the expanded diameter caps snap into the concave cavities, quickly and accurately locking the two frames, simplifying the difficulty of the assembly operation and reducing the assembly workload.

[0015] 2. In the present invention, by fixing the panel flat against the side of the frame laterally and the edge wraps of the panel forming a tightened snap connection state at the four corners of the frame, the connection strength between the frames is increased, and the stability of the rapid assembly of the corridor is improved.

[0016] 3. In the present invention, a top buckle plate is arranged between the top edges of the frames, and a bottom buckle plate is arranged between the bottom edges. The outer wrapping of the right-angle folded edge and the inner support of the concave stamping part are used to maintain the connection gap between the bottom edges of the two frames, improving the connection stability of the two frames. In addition, the two ends of the top buckle plate are connected to the top ends of the arm rods, and the two ends of the bottom buckle plate are connected to the bottom ends of the arm rods, further fixing the shape of the arm rods, generating a mutual restraint force between the entire assembly structures, and making the corridor combination assembly more stable.

[0030] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to 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.

[0031] 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. The frame 1 is formed by welding four hollow square steel materials.

[0032] Positioning holes 41 are opened at the center positions of the end faces on both sides of the frame 1. The positioning holes 41 penetrate through the frame 1. A plurality of nail columns 2 are fixedly arranged respectively at the upper and lower parts of the end faces on both sides of the frame 1. The nail columns 2 are cylindrical, and the ends of the nail columns 2 have enlarged diameter caps.

[0033] As Figure 2-8 shown, there are two arm rods 3. A tension bolt 4 is fixedly penetrated through the center position of the arm rod 3. The tension bolt 4 extends the same length on both sides of the arm rod 3. Concave cavities 61 are opened on one side of the upper part and the other side of the lower part of the arm rod 3. The width of the concave cavity 61 is uniform, and the width of the concave cavity 61 is twice the thickness of the enlarged diameter cap. A plurality of buckle grooves 6 are arranged along the edge of the concave cavity 61. The distribution positions of the buckle grooves 6 are the same as the distribution positions of the nail columns 2, and the buckle grooves 6 are V-shaped. The top part of the V shape is an arc profile adapted to the nail column 2.

[0034] On one side of the top of the arm rod 3 facing away from the concave cavity 61 and one side of the bottom facing away from the concave cavity 61, panels 31 are fixedly welded. Assembly holes are symmetrically opened on the surface of the panel 31. A vertical elongated hole 32 is provided on the surface of the top panel 31.

[0035] The combined assembly operation of the corridor is as follows: As Figure 3-6 shown, the corridor box bodies are arranged end to end, and the frames 1 of adjacent corridor openings are aligned. The two arm rods 3 are placed on both sides between the two frames 1. The tension bolt 4 on the surface of the arm rod 3 is inserted into the positioning hole 41 on the surface of one of the frames 1, and a nut is used to threadedly fasten the tension bolt 4, so that the arm rod 3 is flat against the surface of the frame 1, but the arm rod 3 needs to be kept rotatable. Then, another corridor box body is lifted or moved. The positioning hole 41 of the port frame 1 of this corridor box body is inserted into the other end of the tension bolt 4. The two groups of tension bolts 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 tilted outward from the frame 1, and the bottom is tilted inward from the frame 1. The tension bolt 4 is fastened with a nut to pull the two frames 1 closer. The nail columns 2 on the surfaces of the two frames 1 are linearly aligned until the enlarged diameter caps at the ends of the nail columns 2 are in contact with each other; Pass the lengthened bolt 5 through the strip hole 32 and then connect it to the side of the frame 1. Tighten the lengthened bolt 5 to push the arm rod 3 to rotate around the tension rod 4, so that the arm rod 3 rotates to the vertical state. At this time, the buckle groove 6 correspondingly clamps on the outside of the nail post 2, and the diameter-expanded caps are all clamped into the concave cavity 61. Since the width of the concave cavity 61 is twice the thickness of the diameter-expanded cap, the flat diameter-expanded caps are 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. Use screws to pass through the assembly holes on the surface of the panel 31 and fixedly connect them to the frame 1. Finally, tighten the nuts at both ends of the tension rod 4 to fix the angle of the arm rod 3.

[0036] As Figure 8 shown, chamfers are provided on the edges of the diameter-expanded caps and the inner edges of the buckle grooves 6. During the rotation of the arm rod 3, it is pushed by the inclined surfaces of the chamfers, so that the diameter-expanded caps can be smoothly clamped into the concave cavity 61, which has the function of automatically tightening and aligning the nail post 2.

[0037] As Figure 9-10 shown, edges are bent on both sides of the panel 31 to form flanges, and chamfers are provided on the inner sides of the ends of the flanges. When the rotating arm rod 3 drives the panel 31 to be flat against the frame 1, the flanges of the panel 31 are clamped 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 corner parts of the frame 1, and there is a clamping effect in the four corner areas of the two frames 1, improving the assembly stability.

[0038] The two sides 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 provided at the top and bottom inside the frame 1; As Figure 9-12 shown, both ends of the top buckle 7 have horizontal folding ears. The folding ears of the top buckle 7 are flat against the top of the arm rod 3 and are fixed with screws. Both sides of the top buckle 7 have upward right-angled folding edges, and the right-angled folding edges are clamped on the opposite sides of the top edges of the two frames 1. Concave stamping parts are provided on the surfaces of the top buckles 7, and the concave stamping parts are adapted to be clamped between the top edges of the two frames 1. Through the outer wrapping of the right-angled 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, improving the connection stability of the two frames 1.

[0039] Both ends of the bottom buckle plate 8 have vertical folding ears. The folding ears of the bottom buckle 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 buckle plate 8 have downward right-angled flanges, and the right-angled flanges are stuck on the opposite sides of the bottoms of the two frames 1. The surface of the bottom buckle plate 8 has concave stamping parts, and the concave stamping parts are adapted to be snapped into the space between the bottoms of the two frames 1. Through the outer wrapping of the right-angled flanges and the inner support of the concave stamping parts, the connection gap between the bottoms of the two frames 1 is maintained, and the connection stability of the two frames 1 is improved.

[0040] Both ends of the top buckle plate 7 are connected to the top ends of the arm rods 3, and both ends of the bottom buckle plate 8 are connected to the bottom ends of the arm rods 3, further fixing the shape of the arm rods 3, generating mutual restraint forces among the entire assembly structures, and making the corridor combined assembly more stable.

[0041] Although the embodiments of the present invention have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of the present invention.
