Description

Technical Field

[0001] The utility model relates to the field of station roof steel structures, in particular to a station roof steel structure bracket. Background Art

[0002] With the rapid development of my country's high-speed railways and intercity railways, large-scale railway passenger station buildings have been basically completed. Most of the passenger stations to be built in the future will be small and medium-sized passenger stations. Exploring and studying the architectural design of small and medium-sized passenger stations will be a hot topic for engineering and technical personnel.

[0003] In the prior art, there is a steel structure grid for a railway station building with application number CN210439457U. The above scheme is that "a top rod is welded on the top of the second support rod, and connecting grooves are welded on both ends of the bottom of the top rod, and the first support rods are inserted into the connecting grooves, and a number of auxiliary support rods are welded between the top rod and the cross beam." However, there will be a top on the top rod. After the top is installed, it will encounter wind resistance when encountering strong winds. The wind will blow the top to drive the second support rod and the auxiliary support rod to shake, causing the weld to easily break. It is not convenient to reduce the shaking of the connection through a buffering and shock-absorbing device to reduce the probability of fracture and increase the service life of the facility. How to invent a station roof steel structure bracket to improve these problems has become an urgent problem to be solved by technicians in this field. Utility Model Content

[0004] In order to make up for the above shortcomings, the utility model provides a steel structure bracket for the roof of a station, which aims to improve the problem that there is a top set above the top rod, and there is wind resistance when encountering strong winds after the top is installed. The wind will blow the top and drive the second support rod and the auxiliary support rod to shake, causing the welding joints to easily break.

[0005] The utility model is implemented as follows: a station roof steel structure support, including a steel structure frame body, the steel structure frame body is composed of multiple groups of support columns and beams, and also includes a buffer, the buffer is arranged below the two ends of the beam and is fixedly connected to the support column, and one buffer is arranged between two beams.

[0006] In a preferred technical solution of the present invention, the buffer is fixedly connected to the top of the support column through a lower fixed plate, the two ends of the beam column are fixedly connected to the upper fixed plate, a connecting plate is arranged between the lower fixed plate and the upper fixed plate, and upper limit blocks and lower limit blocks are respectively arranged on the upper and lower sides of the connecting plate, and the connecting plate is connected to the lower fixed plate and the upper fixed plate for limiting movement through the lower limit block and the upper limit block.

[0007] In a preferred technical solution of the present utility model, the lower limit blocks are provided in plurality and are installed transversely on the bottom of the connecting plate, and the upper limit blocks are provided in plurality and are installed longitudinally on the top of the connecting plate.

[0008] In a preferred technical solution of the present invention, the upper limit block and the lower limit block are connected by a plurality of "T"-shaped blocks, a plurality of limit grooves are correspondingly provided on the lower fixed plate and the upper fixed plate, and the upper limit block and the lower limit block are slidingly installed on the upper fixed plate and the lower fixed plate.

[0009] In a preferred technical solution of the utility model, an extrusion plate is provided on both sides of the limiting grooves of the lower fixing plate and the upper fixing plate, which are fixedly connected by a second damping spring, and the extrusion plate is located on both sides of the lower limiting block and the upper limiting block.

[0010] In a preferred technical solution of the utility model, the side walls of the limiting grooves of the lower fixed plate and the upper fixed plate are provided with grooves, one end of the second damping spring is embedded in the grooves of the lower fixed plate and the upper fixed plate, and the other end is fixedly connected to the extrusion plate.

[0011] In a preferred technical solution of the present utility model, a plurality of pulleys are provided at the connection between the upper limit block and the lower limit block and the lower fixing plate and the upper fixing plate.

[0012] In a preferred technical solution of the utility model, two first damping springs are rotatably connected at both ends of the pulley, and the pulley is rotatably installed on the upper limit block and the lower limit block by embedding the pulley.

[0013] The beneficial effect of the utility model is that the utility model obtains a station roof steel structure support through the above design. When in use, when encountering strong winds, the wind will blow the top to drive the beams to shake. The direction of the top offset will be different according to the wind direction. When the top drives the beams to move, the second damping spring and the extrusion plate will squeeze the upper limit block and the upper limit block to make the four directions have buffering force. When the upper fixed plate moves, it will cause friction with the upper limit block and the lower limit block. The friction is reduced through the guidance of the pulley, and the first damping spring is used to reduce the buffering force of the wind. The second damping spring and the extrusion plate are used to reduce the impact of wind on the top, and at the same time, the shaking of the connection is slowed down to reduce the probability of breakage and increase the service life of the facility.
