Description

Technical Field

[0001] The present invention relates to the field of prefabricated steel structure columns, and particularly to a connection structure for prefabricated steel structure columns. Background Art

[0002] Steel structure is one of the main types of building structures, mainly composed of steel beams, steel columns, steel trusses, etc. made of sections and steel plates. During the connection process of steel structure columns, a connection structure for steel structure columns is required for connection. However, the existing connection structure has poor stability during use and is inconvenient for installing steel structures, causing inconvenience to workers. Generally, the connection of steel structure columns is carried out by welding. When connecting, the dimensions of the connection structure need to be accurately measured, and then processes such as cutting are required, which is rather troublesome. The connection problem of steel structure columns is relatively important. Therefore, the inventor has invented a connection structure for prefabricated steel structure columns to solve the connection problem of steel structure columns. Summary of the Invention

[0003] The purpose of the present invention is to solve the deficiencies of the prior art and provide a connection structure for prefabricated steel structure columns.

[0004] The present invention is achieved through the following technical solutions:

[0005] A connection structure for prefabricated steel structure columns includes a first steel structure column, a second steel structure column, and a connection cylinder. The connection cylinder is located between the first steel structure column and the second steel structure column. There are stay ropes connected between the connection cylinder and the first steel structure column and the second steel structure column. Positioning grooves are evenly opened inside the connection cylinder, through holes are evenly opened on the surface of the connection cylinder, sleeves are symmetrically arranged inside the connection cylinder, screw rods are symmetrically sleeved inside the sleeves, a top plate is fixedly installed at the outer end of the screw rod, a collar is sleeved outside the whole formed by the connection cylinder, the screw rod, and the top plate, baffles are symmetrically installed on both sides of the collar, a magnetic ring is sleeved outside the connection cylinder, and a grip block is fixedly installed on the surface of the magnetic ring.

[0006] Preferably, both the first steel structure column and the second steel structure column are square tube structures.

[0007] Preferably, the magnetic ring is made of an electromagnet and is movably fitted outside the connection cylinder.

[0008] Preferably, the collar is made of iron material.

[0009] Preferably, the screw rod is in threaded fit with the sleeve.

[0010] Preferably, the top plate is fixedly connected to the screw rod, and the top plate is a rectangular plate body.

[0011] Preferably, the positioning groove is a long strip structure and is evenly distributed on the side wall of the connection cylinder.

[0012] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0013] Through the cooperation of the magnetic ring and the collar, the present invention can adjust the position of the sleeve, and at the same time, it is also convenient to adjust the direction of the sleeve and the direction of the top plate. By setting the baffle, the function of blocking and limiting is achieved, preventing the top plate from shaking. Through the setting of the top plate and the connection between the screw and the sleeve, a wrench can be used to adjust the top plate, so that the top plate pushes the connecting cylinder, thereby facilitating the support of the connecting cylinder inside the steel structure column and connecting between the steel structure columns, replacing the traditional welding method, which is equivalent to a fastener arranged between the steel structure columns, thus realizing the stable connection of the steel structure columns. By setting the positioning groove, the position of the sleeve can be positioned. Through the adjustment of the top plate and the support inside the connecting cylinder, the connecting cylinder can be tightened inside the steel structure column, realizing the stable connection of the steel structure columns, replacing the traditional welding method and achieving the stable connection of the steel structure columns.

[0018] 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. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0019] Please refer to Figures 1-3 , the present invention provides a technical solution:

[0020] A connecting structure for prefabricated steel columns, comprising a first steel column 1, a second steel column 10 and a connecting cylinder 13. The connecting cylinder 13 is located between the first steel column 1 and the second steel column 10. A pulling rope 2 is connected between the connecting cylinder 13 and the first steel column 1 and the second steel column 10. Positioning grooves 11 are evenly formed inside the connecting cylinder 13, through holes 5 are evenly formed on the surface of the connecting cylinder 13, sleeves 12 are symmetrically arranged inside the connecting cylinder 13, screw rods 9 are symmetrically sleeved inside the sleeves 12, a top plate 7 is fixedly installed at the outer ends of the screw rods 9, a collar 6 is sleeved outside the whole formed by the connecting cylinder 13, the screw rods 9 and the top plate 7, baffles 8 are symmetrically installed on both sides of the collar 6, a magnetic ring 3 is sleeved outside the connecting cylinder 13, and a grip block 4 is fixedly installed on the surface of the magnetic ring 3.

[0021] Both the first steel column 1 and the second steel column 10 are square tube structures.

[0022] The magnetic ring 3 is made of an electromagnet and is movably fitted outside the connecting cylinder 13.

[0023] The collar 6 is made of iron material.

[0024] The screw rod 9 is in threaded fit with the sleeve 12.
