Description

Technical Field

[0001] The utility model relates to the field of steel component welding, in particular to a steel component welding fixing fixture. Background Art

[0002] Steel components are widely used in modern buildings, and they need to be welded during the application process. Figure 1 As shown, an N-shaped steel member 2 is currently required to be welded and fixed to a rectangular steel member 1 in a vertical arrangement. Currently, the N-shaped steel member is usually lifted by hand and then welded. This is not only labor-intensive but also detrimental to improving work efficiency. Currently, there is no fixture that assists in securing the N-shaped steel member to the rectangular steel member. Summary of the Invention

[0003] In view of the deficiencies of the prior art, the present invention provides a steel member welding fixture, which can assist in fixing the N-shaped steel member described in the background art on a rectangular frame plate for welding, thereby effectively solving the problems raised in the background art.

[0004] To achieve the above-mentioned object, the present invention provides the following technical solution: a steel member welding fixture, comprising a first U-shaped frame with a side opening that is engaged with the edge of a rectangular steel member, a first bolt that is screwed inwardly on a clamping portion on the front side of the first U-shaped frame and is engaged with the rectangular steel member by compression, an L-shaped frame plate is fixed to the inner end of the clamping portion on the front side of the first U-shaped frame toward the middle of the rectangular steel member, a first bent portion of the L-shaped frame plate is fixedly connected to the first U-shaped frame, and a second bent portion of the L-shaped frame plate extends forward;

[0005] A second bolt is passed through the second bent part of the L-shaped frame from the outside to the inside, and the protruding end of the second bolt can be rotated to pass through the upper end of the vertical plate. A locking nut is provided on the first bolt on the inner side of the vertical plate, and a third bolt is passed through the lower end of the vertical plate from the outside to the inside and screwed thereon. The inner end of the third bolt can be rotatably screwed on the outside of the second U-shaped frame. The second U-shaped frame is clamped on the supporting part on the upper side of the N-shaped steel member, and the clamping part on the upper side of the second U-shaped frame is screwed downward with a fourth bolt that squeezes the N-shaped steel member.

[0006] As a preferred technical solution, a rubber layer is bonded to the inner surface of the clamping portion at the rear side of the first U-shaped frame.

[0007] As a preferred technical solution, a rubber layer is bonded to the inner surface of the clamping portion at the lower side of the second U-shaped frame.

[0008] As a preferred technical solution, a screw hole that cooperates with the third bolt is embedded on the outer side of the second U-shaped frame.

[0009] As a preferred technical solution, the screw hole is a blind hole that is exposed outwards.

[0010] As a preferred technical solution, an arc-shaped handle is fixedly provided on the outer side of the first U-shaped frame.

[0011] Compared with the prior art, the present invention provides a steel member welding fixture with the following beneficial effects:

[0012] 1. The utility model screws a first bolt which is squeezed and matched with the rectangular steel member inwardly through the clamping part on the front side of the first U-shaped frame, and fixes an L-shaped frame plate at the inner end portion of the clamping part on the front side of the first U-shaped frame toward the middle direction of the rectangular steel member. When in use, the first U-shaped frame and the first bolt are clamped and fixed to the edge of the rectangular steel member to prepare for hanging the N-shaped steel member later. At this time, the third bolt is removed under the vertical plate to separate the vertical plate from the second U-shaped frame.

[0013] 2. The utility model is provided with a third bolt which is screwed through the lower end of the vertical plate from the outside to the inside, and the inner end of the third bolt can be rotatably screwed on the outside of the second U-shaped frame, and the second U-shaped frame is clamped on the supporting part on the upper side of the N-shaped steel member, and the clamping part on the upper side of the second U-shaped frame is screwed downward with a fourth bolt which squeezes the N-shaped steel member. When in use, the second U-shaped frame can be clamped on the edge of the supporting part on the upper side of the N-shaped steel member, and then screwed and fixed by the fourth bolt. Then, the N-shaped steel member is lifted by the staff or equipment, so that the third bolt passes through the lower end of the vertical plate inward and is fixedly connected to the outer side of the second U-shaped frame, thereby playing a hanging and fixing role for the N-shaped steel member as a whole, facilitating subsequent welding, effectively reducing the labor intensity of the staff, and improving welding efficiency and accuracy.

[0014] 3. The utility model is provided with an arc-shaped handle fixed on the outer side of the first U-shaped frame. When in use, the arc-shaped handle facilitates the installation of the first U-shaped frame and is convenient for hanging and storage. BRIEF DESCRIPTION OF THE DRAWINGS

Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention. Example 1

[0023] like Figures 2 to 3 As shown, a steel member welding fixing fixture includes a first U-shaped frame 3 with a side opening that is clamped and matched with the edge of a rectangular steel member 1. The clamping portion on the front side of the first U-shaped frame 3 is screwed inward with a first bolt 31 that is squeezed and matched with the rectangular steel member 1. The inner end of the clamping portion on the front side of the first U-shaped frame 3 facing the middle direction of the rectangular steel member 1 is fixed with an L-shaped frame plate 32. The first bent portion of the L-shaped frame plate 32 is fixedly connected to the first U-shaped frame 3, and the second bent portion of the L-shaped frame plate 32 extends forward. A second bolt 5 is passed through the second bent portion of the L-shaped frame plate 32 from the outside to the inside, and the protruding end of the second bolt 5 can be rotated to pass through the upper end of the vertical plate 4. A locking nut 51 is provided on the first bolt 31 on the inner side of the vertical plate 4, and a third bolt 6 is screwed through the lower end of the vertical plate 4 from the outside to the inside (a first through-hole 41 and a second through-hole 42 are respectively provided at the upper and lower ends of the vertical plate 4), and the inner end of the third bolt 6 can be rotatably screwed on the outside of the second U-shaped frame 7. The second U-shaped frame 7 is clamped on the supporting part on the upper side of the n-shaped steel member 2, and the clamping part on the upper side of the second U-shaped frame 7 is screwed downward with a fourth bolt 71 that squeezes the n-shaped steel member 2.
