Description

A steel strand guide frame system for overall lifting of steel corridors

Technical Field

The utility model belongs to the technical field of building construction, and specifically relates to a steel strand guide frame system for integrally lifting a steel corridor.

Background Art

Steel corridors are corridors commonly used to connect high-rise buildings, mainly composed of steel structures. There are various ways to connect steel corridors, mainly including rigid connection, hinged connection and sliding connection. Rigid connection strengthens the connection between the corridor and the tower, enhancing the overall connectivity; hinged connection relaxes the upper and lower chords at the connection ends, reducing the pressure on the end rods; and sliding connection can coordinate the deformation of high-rise buildings when the rigidity of the corridor is weak.

During construction, the steel corridor often adopts the overall lifting construction method. First, the overall assembly is carried out on the ground, and then the overall lifting is carried out into place through the hydraulic synchronous lifting system. This construction method not only improves the construction efficiency, but also ensures the construction accuracy.

However, due to the different structural styles of steel structures, the structural center of gravity of various styles of steel structures is also different. When different steel structures are lifted as a whole, the shift of the center of gravity can easily lead to unbalanced force, which can easily cause the lifted bracket to overturn.

Utility Model Content

The purpose of the utility model is to provide a steel strand guide frame system for overall lifting of a steel corridor, which can make guiding adjustments to the stretching position of the steel strand according to the different structures of the steel corridor, so as to avoid the overall center of gravity of the steel corridor being unstable after lifting, thereby causing production safety risks.

In order to achieve the above purpose, the technical solution adopted by the utility model is specifically as follows:

A steel strand guide frame system for overall lifting of a steel corridor comprises a column structure, a crossbeam arranged between the column structures, and a traction guide mechanism arranged on the crossbeam; the column structure comprises a plurality of mutually independent column steel frames, an anti-dumping structure respectively connected to each column steel frame, a supporting structure is arranged on one side of each column steel frame, and the crossbeam is installed on the supporting structure of two column steel frames; the traction guide mechanism comprises a slide rail arranged on the crossbeam, a base slidably connected to the slide rail, a winch arranged on the base, and the winch is provided with a lifting steel rope.

Furthermore, the anti-dumping structure includes a plurality of wind ropes, and one end of the wind ropes is fixedly connected to the ground through anchor rods.

Furthermore, the other ends of the guy ropes are respectively connected to different positions of the column steel frame.

As shown in Figures 1 and 2, a steel strand guide frame system for overall lifting of a steel corridor includes a column structure, a crossbeam 7 arranged between the column structures, and a traction guide mechanism arranged on the crossbeam 7; the column structure includes a plurality of independent column steel frames 1, an anti-dumping structure respectively connected to each column steel frame 1, and a supporting structure is arranged on one side of each column steel frame 1, and the crossbeam 7 is installed on the supporting structure of two column steel frames 1; the traction guide mechanism includes a slide rail 4 arranged on the crossbeam 7, a base slidably connected to the slide rail 4, a winch 5 arranged on the base, and a lifting steel rope is arranged on the winch 5.

Compared with the prior art, in the prior art, a method is generally adopted in which a support frame is built upward on the ground below the orthographic projection of the steel corridor setting position, a large-scale high-altitude assembly platform is constructed, and the on-site high-altitude assembly and in-situ welding of the steel corridor are implemented. The disadvantage of this construction method is that a large-scale high-altitude assembly platform needs to be built, and there are many materials for high-altitude engineering, heavy tasks for transporting dispersed materials to high altitudes, and large workloads for high-altitude operations, and high safety requirements, which leads to low work efficiency and high construction costs for setting up steel corridors. Alternatively, an assembly tire frame is set on the ground below the orthographic projection of the steel corridor setting position, and the steel corridor is assembled on the tire frame and then vertically lifted as a whole and welded in place. This construction method has obvious advantages, which not only eliminates the trouble of building a high-altitude assembly platform, but also reduces the workload of transporting dispersed materials to high altitudes and high-altitude construction operations. The low-altitude assembly and assembly of steel corridors on the ground is not only convenient in construction, high in efficiency, but also has strong quality controllability, which is very beneficial to improving construction quality, reducing construction costs and ensuring safe production. However, its disadvantage is that the steel corridor has various structural styles, which makes the center of gravity of the steel corridor easy to change, and it is necessary to rearrange the stretching direction of the steel strand according to the overall center of gravity of the steel corridor. In the present invention, the position of the winch 5 can be driven to change according to specific needs by moving the position of the base, and the winches 5 in different directions are independent of each other, so that the force of the steel corridor during lifting can be controlled by adjusting the position of the winch 5 in different directions, avoiding the problem of overturning caused by uneven force during the lifting process.

The anti-dumping structure includes a plurality of wind ropes 9, and one end of the wind ropes 9 is fixedly connected to the ground through anchor rods. The other ends of the wind ropes 9 are respectively connected to different positions of the column steel frame 1. The column steel frame 1 is fixed by the wind ropes 9 to strengthen the support of the column steel frame 1 and prevent the steel frame from dumping.

The support structure comprises a mounting base plate 2, a support rib plate 3 arranged below the mounting base plate 2, and a support column 8 is arranged between the support rib plate 3 and the mounting base plate 2. The mounting base plate 2 is provided with a cross beam 7 connecting bolt holes 10.

The traction guide mechanism also includes a translation motor, which drives the base to move in the slide rail 4.

In specific use, the guide frame system provided by the utility model needs to first measure the height of obstacles on the ground or between the middle floors below the orthographic projection of the steel corridor, and the front-to-back vertical and horizontal width distance between its outermost edge and the surface of the reinforced concrete structure column of the building, and calculate the center of gravity of the steel corridor according to the overall weight and design shape of the steel corridor, and then plan the overall lifting path of the steel corridor according to the measured distance, and then assemble the steel corridor. Then, according to the designed overall lifting path of the steel corridor, install the column steel frame 1, and install the traction guide mechanism at the corresponding position of the column steel frame 1, and finally perform the overall lifting operation of the steel corridor.
