Description

Technical Field

[0001] The utility model relates to the technical field of building construction, and specifically to a multi-angle fixator for steel structure connection. Background Technique

[0002] Steel structures are mainly composed of steel beams, steel columns, steel trusses and other components made of sections and steel plates. In steel structures, the components or parts are connected by welds, bolts or rivets. Steel structures have the characteristics of high strength, light self-weight, strong deformation ability, good toughness and high reliability. Applying steel structures in construction projects can effectively improve the performance of construction projects, save construction costs, and reduce the use of sand, stone and cement.

[0003] Before welding steel structure parts, it is usually necessary to accurately position the two workpieces to be welded to achieve precise welding of the joints. However, at present, many construction sites still carry out positioning by manual handholding, resulting in low welding accuracy. The welding clamps used in some construction sites are also relatively simple. They need to be screwed onto the workpiece to achieve the clamping function, but there are large errors in manual operation. After the workpieces are clamped, misalignment and deviation often occur, and the clamp needs to be loosened and fixed again, which not only reduces the welding efficiency, but also greatly increases the labor intensity of workers.

[0004] In order to solve the above problems, there is an urgent need for a multi-angle fixator for steel structure connection with good heat dissipation effect. Content of the Utility Model

[0005] The purpose of the utility model is to provide a multi-angle fixator for steel structure connection to solve the problems raised in the above background technique.

[0006] To achieve the above purpose, a multi-angle fixator for steel structure connection is provided, which includes a circular ring. A chute is opened on the circular ring, and the chute is arranged along the curved surface of the circular ring. Fixed angle steels and movable angle steels are respectively arranged on the outer wall of the circular ring;

[0007] The fixed angle steel is fixedly connected with the circular ring, the movable angle steel slides on the outer wall of the circular ring along the chute, and fixing plates are vertically connected to the outer sides of the fixed angle steel and the movable angle steel. Longitudinal adjustment components and transverse adjustment components are arranged on the fixing plates;

[0008] A bolt is installed on the circular ring. One end of the bolt is fixedly connected with the movable angle steel, and the other end passes through the chute and points to the center of the circular ring. The other end of the bolt is threadedly connected with a nut;

[0009] A gasket is also sleeved on the bolt. The gasket is located between the nut and the inner wall of the circular ring. By adjusting the tightness of the nut, the movable angle steel can stay at different positions on the circular ring, so that the fixation of the steel structure at different angles can be realized.

[0010] Further, the longitudinal adjustment component is vertically connected to the fixed plate. The longitudinal adjustment component includes a U-shaped adjustment plate, a positioning hole, and a spring limit plate. A slot for the up-and-down movement of the U-shaped adjustment plate is provided on the fixed plate. The positioning hole is provided on the U-shaped adjustment plate. The spring limit plate is installed on the fixed plate, and both ends of the spring limit plate are provided with limit plates through springs. The limit plates can be inserted into the positioning holes under the action of the springs. By adjusting the position of the longitudinal adjustment component, the height of the transverse adjustment component can be controlled.

[0011] Further, the transverse adjustment component includes a positioning nut, a screw rod, and a clip. The positioning nut is installed at the end of the U-shaped adjustment plate. The screw rod is threadedly installed in the positioning nut. A rotating rod is provided at one end of the screw rod. The clip is installed at the other end of the screw rod. By adjusting the transverse adjustment component, the clip can be made to clamp the steel structure to be fixed.

[0012] Further, one side of the gasket is a curved surface structure corresponding to the ring, and the other side facing the nut is a flat surface structure.

[0013] Further, the number of the positioning holes is several, and the several positioning holes are arranged linearly in sequence.

[0014] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0015] By adjusting the tightness of the nut, the fixing angle of the movable angle steel can be controlled. Subsequently, the steel structure to be welded can be fixed by using the longitudinal adjustment component and the transverse adjustment component. In this way, the steel structure can be fixed during the welding process without worrying about angle or direction deviation.

[0016] By adjusting the longitudinal adjustment component and the transverse adjustment component, the fixing of steel structures with different shapes or different sizes can be achieved, which has high practicability, and the overall structure is simple and convenient to use.

[0028] Please refer to Figure 1-7 As shown, a multi-angle fixator for steel structure connection is provided, including a ring 1. A chute 2 is opened on the ring 1, and the chute 2 is arranged along the curved surface of the ring 1. Fixed angle steel 3 and movable angle steel 8 are respectively arranged on the outer wall of the ring 1.

[0029] The fixed angle steel 3 is fixedly connected to the ring 1. The movable angle steel 8 slides on the outer wall of the ring 1 along the chute 2. Fixed plates 4 are vertically connected to the outer sides of both the fixed angle steel 3 and the movable angle steel 8. A longitudinal adjustment assembly 5 and a transverse adjustment assembly 6 are arranged on the fixed plate 4.

[0030] A bolt 7 is installed on the ring 1. One end of the bolt 7 is fixedly connected to the movable angle steel 8, and the other end passes through the chute 2 and points to the center of the ring 1. The other end of the bolt 7 is threadedly connected to a nut 9;

[0031] A gasket 10 is also sleeved on the bolt 7. One side of the gasket 10 is a curved surface structure corresponding to the ring 1, and the other side facing the nut 9 is a flat surface structure. The gasket 10 is located between the nut 9 and the inner wall of the ring 1. By adjusting the tightness of the nut 9, the movable angle steel 8 can be made to stay at different positions on the ring 1, thus enabling the fixation of the steel structure at different angles;

[0032] As Figure 1-Figure 2 shown:

[0033] The longitudinal adjustment component 5 is perpendicularly connected to the fixed plate 4. The longitudinal adjustment component 5 includes a U-shaped adjustment plate 501, positioning holes 502, and a spring limit plate 503. A slot for the up-and-down movement of the U-shaped adjustment plate 501 is provided on the fixed plate 4. The positioning holes 502 are provided on the U-shaped adjustment plate 501. The number of the positioning holes 502 is several, and several positioning holes 502 are arranged linearly in sequence. The spring limit plate 503 is installed on the fixed plate 4, and both ends of the spring limit plate 503 are provided with limit plates through springs. The limit plates can be inserted into the positioning holes 502 under the action of the springs. By adjusting the position of the longitudinal adjustment component 5, the height of the transverse adjustment component 6 can be controlled. During actual use, the limit plates are clamped into the positioning holes 502 at different heights, so that the height position of the clamping piece 603 can be adjusted. Especially when fixing a circular steel pipe structure, ensuring that the force of the clamping piece 603 acts on the diameter of the steel pipe can obtain a better fixing effect and higher stability;

[0034] It should be noted that the transverse adjustment component 6 includes a positioning nut 601, a screw 602, and a clamping piece 603. The positioning nut 601 is installed at the end of the U-shaped adjustment plate 501. The screw 602 is threadedly installed in the positioning nut 601. One end of the screw 602 is provided with a rotating rod, and the clamping piece 603 is installed at the other end of the screw 602. By adjusting the transverse adjustment component 6, the clamping piece 603 can be made to clamp the steel structure to be fixed;

[0035] It should be noted that in order to find the deflected angle more quickly, corresponding scales (used for measuring angles) can be pre-marked on the outer wall of the ring 1, so as to achieve quick fixation.

[0036] As Figure 3-Figure 6 shown:

[0037] The device is installed on a fixed steel structure by using the fixed angle steel 3, the left end fixing plate 4, the longitudinal adjustment assembly 5 and the transverse adjustment assembly 6 at the left end. Subsequently, the steel structure to be welded or installed is fixed by using the movable angle steel 8, the right end fixing plate 4, the longitudinal adjustment assembly 5 and the transverse adjustment assembly 6 at the right end. Then, loosen the nut 9, adjust the angle to be installed. After the angle is found, tighten the nut 9. At this time, the angle of the movable angle steel 8 is fixed. Then, weld the steel structure together.

[0038] As Figure 3-Figure 6 shown, where Figure 3-Figure 4 is a schematic diagram of the state of welding a square steel pipe structure at different angles; and Figure 5-Figure 6 is a schematic diagram of the state of welding a circular pipe structure at different angles. As Figure 5-Figure 6 shown, in this state, the position of the contact point between the clip 603 and the steel pipe is required to be relatively high. If the contact point is offset, it is easy to cause the circular steel pipe to rotate. At this time, it is necessary to adjust the height of the clip 603 through the longitudinal adjustment assembly 5 so that the position of the clip 603 is approximately at the height of the radius of the circular steel pipe.
