Description

Technical Field

[0001] The utility model relates to the technical field of steel structure processing, in particular to a positioning structure for steel structure welding. Background Art

[0002] Steel structure is a structure made of steel materials and is one of the main types of building structures. It is mainly composed of steel beams, steel columns, steel trusses and other components made of steel sections and steel plates. Rust removal and rust prevention processes such as silanization, pure manganese phosphating, water washing and drying, and galvanizing are used. Welds, bolts or rivets are usually used to connect the various components or parts. Due to its light weight and simple construction, it is widely used in large factories, venues, super high-rise buildings, bridges and other fields. Steel structures are prone to rust. Generally, steel structures need to be rust-proofed, galvanized or painted, and regularly maintained. During the construction of bridges, multiple groups of steel columns for connecting or installing structural parts need to be welded on the surface of steel beams or beam slab ribs. However, during the welding process, these steel columns need to be positioned so that they are vertical or inclined and abut against the steel beams or beam slab ribs.

[0003] In the existing technology, one person usually holds the steel column to limit its position while another person performs the welding operation. As the operation time increases, the supporting person is very likely to become fatigued, resulting in a decrease in the accuracy of hand control, causing the steel column to shake during the welding process, and then causing problems such as welding position offset or angle tilt, resulting in the finished component failing to meet the design requirements and requiring subsequent rework. For this reason, we propose a positioning structure for steel structure welding. Utility Model Content

[0004] The purpose of the utility model is to solve the shortcomings in the prior art and to propose a positioning structure for steel structure welding.

[0005] In order to achieve the above-mentioned purpose, the utility model adopts the following technical solution: a positioning structure for steel structure welding, comprising a base, a positioning plate fixedly connected to the top of the base, a steel column adsorption groove provided on one side of the positioning plate, a magnetic plate fixedly connected to the inside of the steel column adsorption groove, and the magnetic plate is used to adsorb and position the steel column; a side support mechanism is provided on the other side of the positioning plate, and the side support mechanism is used to change the placement of the positioning plate.

[0006] Preferably, the positioning plate is in the shape of a right-angled trapezoid as a whole, and a welding groove is provided on one side of the connection between the base and the positioning plate.

[0007] Preferably, the side support mechanism includes a spring hinge fixedly installed on one end of the inclined surface of the positioning plate, one side of the spring hinge is fixedly connected to the side plate by bolts, the inclined surface of the positioning plate is provided with a slide groove, and an adjustment slider is slidably installed inside the slide groove.

[0008] Preferably, the adjusting slider is trapezoidal as a whole, and adjusting rods are fixedly connected to both sides of the adjusting slider.

[0009] Preferably, a limiting groove is formed at the top end of the side lying plate, and a rubber strip matching the limiting groove is fixed at the bottom end of the adjusting slider.

[0010] Preferably, a hollowed-out groove is formed on the side surface of the positioning plate, and a reinforcing rib is fixedly connected to the inner wall of the hollowed-out groove.

[0012] Preferably, a magnet is fixedly connected inside the side lying plate, and an anti-slip groove is formed at the bottom end of the side lying plate.

[0013] Beneficial effects:

[0014] 1. The utility model positions and supports the positioning plate through the base, and uses the magnetic attraction plate fixedly connected inside the steel column adsorption groove on one side of the positioning plate to adsorb and limit the steel column, so that the steel column and the steel plate are vertically abutted against each other. The positioning plate is used to support and position the steel column to prevent the steel column from shifting and toppling, facilitating the welding operation between the steel column and the steel plate. By providing the side lying plate on the inclined surface side of the positioning plate, the positioning plate can be supported and lifted with the side lying plate as the base, changing the angle of the steel column adsorption groove on the vertical surface of the positioning plate, and then tilting and placing the steel column to meet the positioning requirements for inclined welding of the steel column, preventing the steel column from shaking during the welding operation, and improving the efficiency and accuracy of steel column welding.

[0015] 2. The utility model moves the adjusting slider installed inside the sliding chute towards the spring hinge through the sliding of the adjusting slider. Taking the spring hinge as the base point, the trapezoidal adjusting slider as a whole expands the gap between the inclined surface of the positioning plate and the side lying plate, making the vertical surface of the positioning plate gradually tilt, and then changing the angle of the steel column adsorbed and fixed inside the steel column adsorption groove on the vertical surface of the positioning plate, meeting the positioning requirements for adjusting the inclination angle of the steel column during inclined welding of the steel column, so as to improve the accuracy of inclined welding of the steel column.

[0023] In order to make the technical means, creative features, achieved purposes and functions implemented by the present utility model easy to understand, the present utility model will be further described below in conjunction with specific embodiments and the accompanying drawings. However, the following embodiments are only the preferred embodiments of the present utility model and not all of them. Based on the embodiments in the implementation manners, other embodiments obtained by those skilled in the art without creative efforts all fall within the protection scope of the present utility model.

[0024] The specific embodiments of the present utility model will be described below with reference to the accompanying drawings.

[0025] Refer to Figures 1 - 5 , a positioning structure for steel structure welding, including a base 1, a positioning plate 2 is fixedly connected to the top end of the base 1, a steel column adsorption groove 4 is opened on one side of the positioning plate 2, and a magnetic adsorption plate 5 is fixedly connected inside the steel column adsorption groove 4. The magnetic adsorption plate 5 is used to adsorb and position the steel column; a lateral lying support mechanism 3 is arranged on the other side of the positioning plate 2, and the lateral lying support mechanism 3 is used to change the placement form of the positioning plate 2.

[0026] The positioning plate 2 is positioned and supported by the base 1, and the steel column is adsorbed and limited by the magnetic adsorption plate 5 fixedly connected inside the steel column adsorption groove 4 on one side of the positioning plate 2, so that the steel column and the steel plate are vertically abutted against each other, which is convenient for completing the welding operation between the steel column and the steel plate. Through the lateral lying support mechanism 3 arranged on the other side of the positioning plate 2, it is convenient to support and carry the positioning plate 2 with the lateral lying support mechanism 3 as the bottom surface, change the orientation of the steel column adsorbed and fixed by the magnetic adsorption plate 5, and thus facilitate meeting the positioning requirements for the welding of inclined steel columns.

[0027] As Figures 1 - 3 shown, the overall shape of the positioning plate 2 is a right trapezoid, and a welding groove 6 is opened on one side of the connection between the base 1 and the positioning plate 2. The welding groove 6 can reserve the operation space at the welding position, which is convenient for the welding torch to perform the welding operation on the steel column.

[0028] As Figures 1 - 2As shown in the figure, the side-lying support mechanism 3 includes a spring hinge 7 fixedly installed at one end of the inclined surface of the positioning plate 2. One side of the spring hinge 7 is fixedly connected to a side-lying plate 8 by bolts. A sliding groove 9 is provided on the inclined surface of the positioning plate 2, and an adjusting slider 10 is slidably installed inside the sliding groove 9. The adjusting slider 10 is trapezoidal as a whole, and adjusting rods 11 are fixedly connected to both sides of the adjusting slider 10. By sliding the adjusting slider 10 slidably installed inside the sliding groove 9, the adjusting slider 10 is moved towards the spring hinge 7. Taking the spring hinge 7 as the base point, the gap between the inclined surface of the positioning plate 2 and the side-lying plate 8 is expanded by using the trapezoidal adjusting slider 10 as a whole, so as to adjust the inclination angle of the vertical surface of the positioning plate 2 and change the adsorption angle of the steel column inside the steel column adsorption groove 4 on the vertical surface of the positioning plate 2, meeting the positioning requirements when the steel column is inclined for welding.

[0029] As Figures 1 - 5 shown in the figure, a limiting groove 12 is provided at the top end of the side-lying plate 8, and a rubber strip matching the limiting groove 12 is fixed at the bottom end of the adjusting slider 10. The limiting groove 12 provided at the top end of the side-lying plate 8 can cooperate with the rubber strip at the bottom end of the adjusting slider 10 to limit the adjusting slider 10, thereby maintaining the distance between the inclined surface of the positioning plate 2 and the side-lying plate 8, and further limiting the inclination of the steel column adsorbed by the steel column adsorption groove 4, avoiding the situation that the adjusting slider 10 moves during the welding process, resulting in a change in the position of the steel column and affecting the welding operation.

[0030] As Figures 1 - 5 shown in the figure, a hollow groove 13 is provided on the side surface of the positioning plate 2, and a reinforcing rib 14 is fixedly connected to the inner wall of the hollow groove 13. By providing the hollow groove 13 on the side surface of the positioning plate 2, the weight and wind resistance of the positioning plate 2 can be reduced, facilitating the lifting and moving of the entire device for use outdoors. The reinforcing rib 14 fixedly connected to the inner wall of the hollow groove 13 can improve the compressive strength of the entire positioning plate 2, and the setting of the reinforcing rib 14 also facilitates the lifting and carrying of the entire device.

[0031] As Figure 3 shown in the figure, a counterweight block 15 is filled inside the base 1, and the overall weight of the base 1 is greater than the overall weight of the positioning plate 2. The bottom end of the base 1 is made of a magnetic plate. The counterweight block 15 filled inside the base 1 can enhance the overall weight of the base 1, improve the stability of the equipment during use and placement, and avoid the situation that the base 1 tilts due to the center of gravity shifting when the positioning plate 2 supports the steel column. At the same time, the base 1 with a magnetic plate at the bottom end can be adsorbed to the steel plate, thereby limiting the placement position of the entire device.

[0032] As Figures 1 - 3 shown in the figure, a magnet is fixedly connected inside the side-lying plate 8, and an anti-slip groove is provided at the bottom end of the side-lying plate 8. The magnet fixedly connected inside the side-lying plate 8 can be adsorbed and fixed to the steel plate.

[0033] Working principle of the utility model: Adsorb and fix the steel column to be vertically welded inside the steel column adsorption groove 4 on one side of the positioning plate 2, then adsorb and fix the base 1 on the steel plate where the steel column needs to be welded. Then, by adjusting the position of the base 1, align and abut the welding points of the steel column and the steel plate, and the positioning operation before steel column welding can be completed. When it is necessary to weld the steel column obliquely, tilt the positioning plate 2 so that the side-lying plate 8 on the inclined surface side of the positioning plate 2 adsorbs to the steel plate. After the side-lying plate 8 is adsorbed and fixed to the steel plate, the steel column adsorption groove 4 on the vertical surface of the positioning plate 2 will be inclined, and then the steel column placed inside the steel column adsorption groove 4 will be inclined. Then, push the steel column to move so that one end of the steel column aligns and abuts against the inclined welding point, and the positioning requirement for inclined welding of the steel column is completed. At the same time, according to the angle requirement of inclined welding, toggle the adjusting rods 11 on both sides of the adjusting slider 10 so that the adjusting slider 10 slides along the chute 9 towards the spring hinge 7, and the distance between the inclined surface of the positioning plate 2 and the side-lying plate 8 can be expanded, thereby adjusting the inclination angle of the steel column adsorption groove 4 and changing the inclination of the steel column to meet the angle adjustment requirement during inclined welding of the steel column.
