Description

Technical Field

[0001] This invention relates to the field of corridor installation technology, specifically to a rapid installation structure and method for steel structure corridors. Background Technology

[0002] In many steel structure connecting corridor installations, scaffolding is often erected, and the corridor is welded between two buildings. This method not only increases the danger of working at heights but also increases construction time and reduces flexibility. Therefore, existing technology involves pre-welding the corridor on the ground and then directly installing it between the two buildings. While this method is faster, it places high demands on the installation structure, installation time, and the complexity of the work. The structural design is also a key factor affecting the safe use and lifespan of the connecting corridor. Current methods use cranes to lift the corridor, connect it, and then secure it with bolts. This method significantly reduces the safety performance and lifespan of the connecting corridor. Summary of the Invention

[0003] The purpose of this invention is to provide a rapid installation structure and method for steel structure corridors, which has strong stability and can not only ensure the safety performance of the corridor, but also ensure rapid installation and overall stability after installation, thereby solving the problems mentioned in the background art.

[0004] To achieve the above objectives, the present invention provides the following technical solution:

[0005] A rapid installation structure for a steel structure corridor includes a corridor and a building. A first corridor insert plate and a second corridor insert plate are welded to the top and bottom of both ends of the corridor, respectively. Two steel sections perpendicular to the corridor are fixed to the cast-in-place beam of the building. A first corridor connecting seat and a second corridor connecting seat are welded to the steel sections. Both the first and second corridor connecting seats have slots that match the first and second corridor insert plates. A support plate supporting the bottom of the corridor is welded to the bottom of the second corridor insert plate. A support bracket is welded to the bottom of the support plate to improve its supporting force and stability. A hydraulic cylinder is connected to the inside of the support bracket via a second hydraulic cylinder connector. A spring is fitted onto the hydraulic cylinder. One end of the hydraulic cylinder is fixedly connected to the bottom of the corridor via a first hydraulic cylinder connector. The hydraulic cylinder and spring provide support and shock absorption for the corridor.

[0006] Several second and first diagonal tie rod connectors are welded onto the square steel of the connecting corridor at the top. A third and fourth diagonal tie rod connector are installed on the cast-in-place beam. The second diagonal tie rod connectors are connected to the third diagonal tie rod connectors via second diagonal tie rods, and the first diagonal tie rod connectors are connected to the fourth diagonal tie rod connectors via first diagonal tie rods. This is used to increase the tension of the connecting corridor and improve its stability and safety.

[0007] Preferably, a plurality of connecting plates are welded onto the steel profile. The connecting plates pass through the cast beam and are welded to the first connecting corridor connecting seat, the second connecting corridor connecting seat, the supporting inclined frame, the third inclined tie rod connecting head, and the fourth inclined tie rod connecting head, respectively. The first connecting corridor connecting seat, the second connecting corridor connecting seat, the supporting inclined frame, the third inclined tie rod connecting head, and the fourth inclined tie rod connecting head are all installed on the cast beam by bolts to reinforce the connection and ensure the stability and firmness of the connection.

[0008] Preferably, the supporting slide is made of steel plate, and bolt holes are provided on the supporting slide for fixing the corridor to the supporting slide. The supporting slide is also welded to the supporting inclined frame to form a triangular stable structure, thereby improving the supporting force on the corridor.

[0009] Preferably, the second hydraulic cylinder connector is welded into the U-shaped groove of the supporting inclined frame. One end of the hydraulic cylinder is connected to the second hydraulic cylinder connector via a connecting shaft. The first hydraulic cylinder connector is welded to the bottom of the connecting corridor. The first hydraulic cylinder connector is connected to the U-shaped connector at the end of the hydraulic cylinder via a connecting shaft. The extension of the hydraulic cylinder provides upward support to the connecting corridor. The hydraulic cylinder and spring have a shock absorption effect.

[0010] Preferably, the first connecting corridor insert plate and the second connecting corridor insert plate at both ends are connected to the first connecting corridor connecting seat and the second connecting corridor connecting seat by insertion, which is used for quick positioning and installation during the installation of the connecting corridor. The first connecting corridor insert plate, the second connecting corridor insert plate, the first connecting corridor connecting seat, and the second connecting corridor connecting seat are all provided with mounting holes, and the first connecting corridor insert plate, the second connecting corridor insert plate, the first connecting corridor connecting seat, and the second connecting corridor connecting seat are fixed together with the steel profile by bolts.

[0011] Preferably, the first connecting corridor connecting seat and the second connecting corridor connecting seat are located at any position on the cast beam or wall surface.

[0012] Preferably, the keel of the connecting corridor is made by welding the square steel of the connecting corridor, and the first connecting corridor insert plate and the second connecting corridor insert plate are both welded to the square steel of the connecting corridor.

[0013] A rapid installation method for a steel structure connecting corridor includes the following steps:

[0014] S1: First, install the first connecting corridor and the second connecting corridor. Install steel sections on the cast beam of the building. Fix the first connecting corridor, the second connecting corridor, the support bracket, the third tie rod connector, and the fourth tie rod connector to the steel sections by welding and bolting, so that the steel sections, the cast beam, the first connecting corridor, and the second connecting corridor are integrated into one unit.

[0015] S2: Lift the connecting corridor using a crane, insert the first connecting corridor plates at both ends into the first connecting corridor connecting seats, insert the second connecting corridor plates at both ends into the second connecting corridor connecting seats, and then fix the first connecting corridor plates, the first connecting corridor connecting seats, the steel profiles, the cast-in-place beams or walls together; fix the second connecting corridor plates, the second connecting corridor connecting seats, the steel profiles, the cast-in-place beams or walls together.

[0016] S3: Then connect one end of the hydraulic cylinder to the first hydraulic cylinder connector welded to the bottom of the connecting corridor via the connecting shaft. Use the hydraulic cylinder to inject hydraulic oil, so that the bottom of the connecting corridor is lifted up to provide support. The hydraulic cylinder is fitted with a spring, which can also serve as a shock absorber.

[0017] S4: After the bottom of the connecting corridor is installed, the first and second diagonal braces are installed on the top of the connecting corridor. The first diagonal brace is used to diagonally pull the connection point of the connecting corridor, and the second diagonal brace is used to diagonally pull the middle of the connecting corridor, thereby ensuring that the connecting corridor is safer and more stable.

[0018] Compared with the prior art, the beneficial effects of the present invention are:

[0019] 1. This invention has strong stability performance. It uses multiple connecting seats for the corridor to be fixed together with the cast-in-place beam and steel profile, so that the connection between the entire corridor and the connecting seats is equivalent to the connection with the entire building. At the same time, support components and hydraulic shock absorbers are set on the cast-in-place beam to further improve the stability performance of the corridor. Multiple diagonal tie rods are used at the top of the corridor to connect the middle part of the corridor to the building, reducing the weight of the corridor and improving safety performance.

[0020] 2. This invention allows for rapid positioning and installation of connecting corridors, improving installation speed, efficiency, and flexibility, providing great convenience to construction workers, while reducing safety risks. Attached Figure Description

Finally, install the first connecting corridor insert plates 15, the first connecting corridor connecting seat 5, the steel profile 4, and the cast-in-place beam 3... Alternatively, the second connecting corridor plate 16, the second connecting corridor connecting seat 6, the steel section 4, the cast beam 3, or the wall can be fixed together; then, one end of the hydraulic cylinder 1001 is connected to the first hydraulic cylinder connector 1003 welded to the bottom of the connecting corridor 1 through the connecting shaft. Hydraulic oil is injected into the hydraulic cylinder 1001, thereby lifting the bottom of the connecting corridor 1 and providing support. The hydraulic cylinder 1001 is fitted with a spring 1002, which also serves to dampen shocks. After the bottom of the connecting corridor 1 is installed, the first diagonal tie rod 7 and the second diagonal tie rod 8 are installed on the top of the connecting corridor 1.
