Description

Technical Field

[0001] The utility model relates to the technical field of load-bearing steel structure column connection structures, in particular to a load-bearing steel structure column connection structure. Background Art

[0002] The load-bearing steel structure column is the main structural support of the building. It bears the weight of the floor and roof and is a key part of the safety and stability of the building. In terms of materials, the load-bearing steel structure column is usually made of steel or concrete, and some of them are made of wood. The steel column has the characteristics of high strength and light weight, while the concrete column has more load-bearing capacity and can adapt to various building structure requirements. In terms of shape, the load-bearing column has a variety of shapes, mainly including round, square, rectangular, etc. Different shapes are selected according to the needs of the building structure. In terms of manufacturing process, the load-bearing column can be manufactured by casting, forging, welding and other processes. Among them, the casting process is more commonly used, which can produce complex shapes and large structures. At present, when welding and assembling the load-bearing steel structure column, it is necessary to restrict the two load-bearing steel structure columns to keep them parallel. In addition, the placement stability of the two needs to be maintained during welding. However, when welding, the two load-bearing steel structure columns are mostly placed horizontally and then welded. Such a welding mechanism has poor welding accuracy and is not conducive to fast and accurate welding. Therefore, it is necessary to provide a connection structure of the load-bearing steel structure column to solve the above technical problems. Utility Model Content

[0003] The purpose of the utility model is to provide a connection structure of load-bearing steel structure columns to solve the problems raised in the above background technology.

[0004] In order to solve the above technical problems, the technical solution adopted by the utility model is:

[0005] A connection structure for load-bearing steel structure columns, comprising steel columns; two of the steel columns are symmetrically arranged, a mounting box is provided between the two steel columns, a bidirectional screw is rotatably connected inside the mounting box, both ends of the bidirectional screw are threadedly connected to lifting plates, a mounting seat is fixedly installed on the upper surface of one of the lifting plates, a worm is rotatably connected inside the mounting seat, a worm wheel is rotatably connected inside the mounting seat, and the worm and the worm wheel are meshingly connected, one end of the bidirectional screw passes through the side wall of the mounting seat and is fixedly connected to the center of the worm wheel, both ends of the two lifting plates are rotatably connected to limiting components, and one end of the limiting component passes through the side wall of the mounting box and cooperates with the bidirectional screw.

[0006] A further improvement of the technical solution of the utility model is that: at present, when welding and assembling the load-bearing steel structure columns, it is necessary to restrict the two load-bearing steel structure columns to keep them parallel. In addition, the placement stability of the two needs to be maintained during welding. However, when welding is performed, the two load-bearing steel structure columns are mostly placed horizontally and then the welding work is performed. Such a welding mechanism has poor welding accuracy and is not conducive to fast and accurate welding. In this solution, when it is necessary to weld the two steel columns, the two steel columns are placed symmetrically at this time. Subsequently, the staff drives the worm gear to rotate through the worm gear, and drives the bidirectional lead screw to rotate through the worm gear, thereby realizing the movement of the two lifting plates towards each other. As the two lifting plates move towards each other, the restriction component will be driven to deform, and the steel column will be clamped and restricted by the restriction component, so that the two steel columns remain stable, which is more convenient for welding work, and the accuracy of the device when welding the steel columns is increased, so that the steel columns can be better welded.

[0007] The above technical solution is adopted, in which one end of the worm screw passes through the side wall of the mounting seat and is fixedly mounted with a hand wheel.

[0008] A further improvement of the technical solution of the utility model is that the setting of the handwheel makes it convenient for the staff to drive the worm to rotate, and then the worm can drive the worm wheel to rotate, so that it is more convenient for the staff to drive the device and increase the convenience of using the device.

[0009] The above-mentioned technical scheme is adopted, and the limiting component in the scheme includes a transmission rod, and the four transmission rods are rotatably connected to the two ends of the two lifting plates respectively, and the ends of the two transmission rods away from the lifting plates are rotatably connected to the two ends of the mounting plate respectively, a connecting block is fixedly installed on one side of the mounting plate, and an extrusion block is fixedly installed on the side of the connecting block away from the mounting plate, a bevel gear group is fixedly installed at the center of the bidirectional screw rod, one end of the bevel gear group is fixedly connected to one end of the transmission gear, and the transmission gear is rotatably connected to the inside of the mounting box, tooth plates are provided on both sides of the transmission gear, and the tooth plates are meshed with the transmission gear, the tooth plate is slidably connected to the inside of the mounting box, and a clamping seat is fixedly installed on one end of the tooth plate, and one end of the clamping seat is slidably connected to the mounting box.

[0010] A further improvement of the technical solution of the utility model is that when the lifting plates move towards each other, the lifting plates will drive the two mounting plates to move in opposite directions through the transmission of the transmission rod. The side walls of the mounting plates are fixedly installed with extrusion blocks through connecting blocks. As the mounting plates move, the extrusion blocks will synchronously follow the mounting plates to move in opposite directions. At the same time, as the lifting plates move, the bidirectional screw rod will drive the transmission gear to rotate through the bevel gear set. When the transmission gear rotates, it will cooperate with the tooth plate to move towards each other. As the tooth plates move towards each other, the tooth plates will cooperate with the clamping seat to contact the steel column, and then cooperate with the extrusion block to clamp the steel column.

[0011] The above technical solution is adopted, in which one end of the extrusion block is provided with a protective pattern.

[0012] A further improvement of the technical solution of the utility model is that the anti-slip pattern at the end of the extrusion block can increase the friction between the extrusion block and the side wall of the steel column, so that the extrusion block will not move when extruding the steel column, thereby increasing the restraining stability of the device on the steel column, thereby facilitating the staff to perform welding processing on the steel column.

[0013] The above technical solution is adopted, and both ends of the mounting seat and the mounting plate in the solution are provided with mounting grooves that cooperate with the transmission rod.

[0014] A further improvement of the technical solution of the utility model is that the mounting grooves at both ends of the mounting seat and the mounting plate facilitate the rotational connection between the mounting seat and the mounting plate and the transmission rod, increase the installation convenience of the device, thereby increasing the assembly fit between the device components, and making the device more stable when in use.

[0015] The above technical solution is adopted, in which one end of the clamping seat is provided with a U-shaped seat which is clamped and matched with the steel column.

[0016] A further improvement of the technical solution of the utility model is that the U-shaped seat arranged at the end of the socket can cooperate with the extrusion block to clamp and restrict the steel column. In addition, the U-shaped seat at the end of the socket can increase the degree of fit between the socket and the steel column, so that the restriction component can better restrict the steel column and increase the stability of the device when in use.

[0017] The above technical solution is adopted, in which one end of the bidirectional screw rod is provided with a protrusion which is mutually pressed and matched with the lifting plate.

[0018] A further improvement of the technical solution of the utility model is that the protrusion at the end of the bidirectional screw rod prevents the bidirectional screw rod from excessively rotating and detaching from the inside of the mounting box, thereby making the device more stable when in use.

[0019] Due to the adoption of the above technical solution, the utility model has achieved the following technical progress compared with the prior art:

[0020] 1. The utility model provides a connection structure for load-bearing steel structure columns. By setting a limiting component, the position of two steel columns can be limited. The device that can be set at both ends of the steel column can quickly limit the steel column, thereby increasing the accuracy of welding, making it convenient for workers to connect the load-bearing steel structure columns, and increasing the stability and convenience of the device when in use. In addition, the self-locking mechanism of the worm gear allows the device to remain stable during use, thereby making the device more convenient to use.

[0021] 2. The utility model provides a connection structure for load-bearing steel structure columns. The limiting components of the bidirectional synchronous movement mechanism can facilitate the device to limit the position of the steel column, thereby increasing the speed of the device when in use, and can be quickly installed and disassembled, making the device more convenient to operate when in use and can be better processed.

[0033] In this embodiment, when it is necessary to weld two steel columns 1, the two steel columns 1 are placed symmetrically. Subsequently, the staff drives the worm wheel 7 to rotate through the worm 6, and drives the bidirectional screw 3 to rotate through the worm wheel 7, thereby realizing the two lifting plates 4 to move toward each other. As the two lifting plates 4 move toward each other, the limiting component will be driven to deform, and the steel column 1 will be clamped and restricted by the limiting component, so that the two steel columns 1 remain stable, which makes welding work more convenient, increases the accuracy of the device when welding the steel column 1, and thus can better weld the steel column 1.

[0034] Example 2

[0035] like Figure 1-6 As shown, based on Example 1, the utility model provides a technical solution: preferably, one end of the worm 6 passes through the side wall of the mounting seat 5 and is fixedly mounted with a hand wheel 8.

A connecting block 11 is fixedly installed on one side of the mounting plate 10, and an extrusion block 12 is fixedly installed on the side of the connecting block 11 away from the mounting plate 10. A bevel gear set 13 is fixedly installed in the center of the bidirectional screw rod 3, one end of the bevel gear set 13 is fixedly connected to one end of a transmission gear 14, and the transmission gear 14 is rotatably connected to the inside of the mounting box 2, tooth plates 15 are provided on both sides of the transmission gear 14, and the tooth plates 15 are meshed and connected with the transmission gear 14, the tooth plate 15 is slidably connected to the inside of the mounting box 2, and a clamping seat 16 is fixedly installed on one end of the tooth plate 15, and one end of the clamping seat 16 is slidably connected to the mounting box 2.

[0039] In this embodiment, when the lifting plate 4 moves towards each other, the lifting plate 4 will drive the two mounting plates 10 to move in opposite directions through the transmission of the transmission rod 9. The side walls of the mounting plates 10 are fixedly installed with extrusion blocks 12 through connecting blocks 11. As the mounting plates 10 move, the extrusion blocks 12 will synchronously follow the mounting plates 10 to move in opposite directions. At the same time, as the lifting plate 4 moves, the bidirectional screw rod 3 will drive the transmission gear 14 to rotate through the bevel gear set 13, and when the transmission gear 14 rotates, it will cooperate with the tooth plate 15 to move towards each other. As the tooth plate 15 moves towards each other, the tooth plate 15 will cooperate with the clamping seat 16 to contact the steel column 1, and then cooperate with the extrusion block 12 to clamp the steel column 1.

[0040] Example 4

[0041] like Figure 6 As shown, based on Example 1, the utility model provides a technical solution: preferably, a protective pattern is provided at one end of the extrusion block 12.

[0042] In this embodiment, the anti-slip groove setting at the end of the extrusion block 12 can increase the friction between the extrusion block 12 and the side wall of the steel column 1, so that the extrusion block 12 will not move when extruding the steel column 1, thereby increasing the restraining stability of the device on the steel column 1, thereby facilitating the staff to perform welding processing on the steel column 1.

[0043] like Figure 3-6 As shown, preferably, both ends of the mounting seat 5 and the mounting plate 10 are provided with mounting grooves for mounting and cooperating with the transmission rod 9 .

[0044] In this embodiment, the mounting grooves at both ends of the mounting seat 5 and the mounting plate 10 are arranged to facilitate the rotational connection between the mounting seat 5 and the mounting plate 10 and the transmission rod 9, thereby increasing the installation convenience of the device, thereby increasing the assembly fit between the device components, and making the device more stable during use.

[0045] like Figure 3-5 As shown, preferably, one end of the clamping seat 16 is provided with a U-shaped seat that is clamped and matched with the steel column 1.

[0046] In this embodiment, the U-shaped seat provided at the end of the socket 16 can cooperate with the extrusion block 12 to clamp and restrict the steel column 1. In addition, the U-shaped seat at the end of the socket 16 can increase the degree of fit between the socket 16 and the steel column 1, so that the restriction component can better restrict the steel column 1 and increase the stability of the device during use.

[0047] like Figure 2 As shown, preferably, one end of the bidirectional screw rod 3 is provided with a protrusion which is pressed and matched with the lifting plate 4.

[0048] In this embodiment, the protrusion at the end of the bidirectional screw rod 3 prevents the bidirectional screw rod 3 from excessively rotating and detaching from the inside of the mounting box 2, thereby making the device more stable when in use.

[0049] The following is a detailed description of the working principle of the connection structure of the load-bearing steel structure column.

[0050] like Figure 1-6 As shown, when it is necessary to weld two steel columns 1, at this time, the two steel columns 1 are placed symmetrically, and then the staff drives the worm wheel 7 to rotate through the worm 6, and drives the bidirectional lead screw 3 to rotate through the worm wheel 7, thereby realizing the movement of the two lifting plates 4 towards each other. When the lifting plates 4 move towards each other, the lifting plates 4 will drive the two mounting plates 10 to move in opposite directions through the transmission of the transmission rod 9. The side walls of the mounting plates 10 are fixedly installed with extrusion blocks 12 through connecting blocks 11. As the mounting plates 10 move, the extrusion blocks 12 will synchronously follow the mounting plates 10 to move in opposite directions. At the same time, as the lifting plates 4 move, the bidirectional lead screw 3 will drive the transmission gear 14 to rotate through the bevel gear set 13, and the transmission gear 14 will cooperate with the tooth plate 15 to move towards each other when rotating. As the tooth plate 15 moves towards each other, the tooth plate 15 will cooperate with the clamping seat 16 to contact the steel column 1, and then cooperate with the extrusion block 12 to clamp the steel column 1.

[0051] The above generally describes the present invention in detail, but it is obvious to a person skilled in the art that some modifications or improvements can be made to the present invention. Therefore, modifications or improvements that do not depart from the spirit of the present invention are within the scope of protection of the present invention.
