[0002] The building metal support structure is a device used to support and fix components, usually made of metal materials, and is a very common engineering structure. The support is usually composed of a support head, a support arm, a support rod, and a connector, and is used in the construction field after welding.

The workpiece can be placed horizontally on the bottom support plate, and a left lower support and a right lower support are respectively arranged vertically upward at the left and right center positions above the bottom support plate. A slidable left upper support is arranged inside the upper end of the left lower support, and the two are positioned by bolts on the outside. A slidable right upper support is arranged inside the upper end of the right lower support, and the two are positioned by bolts on the outside; the height can be adjusted arbitrarily, and the middle cross beam, the upper cross beam, the lower cross beam, and the vertical cross beam are all made of industrial aluminum profiles, and the downward surface is provided with a through V-shaped groove, and a V-shaped connecting hanger that can adjust the angle at will is arranged in the V-shaped groove, and the bottom of the V-shaped connecting hanger is provided with a hook, a lifting ring, and a clamp in sequence, and the clamp is used to clamp the steel structure; the V-shaped connecting hanger can be adjusted at any angle, and the steel structure clamped by the clamp can also be adjusted to any angle accordingly.

In conventional welding, workers need to hold the brackets for support before welding, and the high temperature and heat radiation generated by welding can easily cause skin burns to workers. Therefore, we propose an auxiliary device for welding of building metal bracket structures. Utility Model Content

[0033] Furthermore, during the welding process, the metal bracket is placed on the support plate 11, and then the metal brackets are spliced ​​and limited by the limit assembly 13 and the clamping assembly 14. After the fixation is completed, the worker performs welding. When the length of the metal bracket exceeds the support plate 11, the two groups of bases 1 can be spliced, and the two bases 1 are placed side by side. The limit pin 51 is pressed so that the limit pin 51 is retracted into the limit rod 5 under force, and the fourth spring 53 is compressed, and then the limit rod 5 is inserted into the connecting hole 15. When the angle of the limit pin 51 is aligned with the limit hole 16, the fourth spring 53 automatically resets the limit pin 51 through the elastic force, passes through the limit hole 16, and is fixed. Then the limit rod 5 is simultaneously inserted into the connecting hole 15 of the other base 1, so that the two bases 1 can be spliced, and then the support plate 11 is installed to complete the expansion of the range of the support plate 11.

[0034] Specifically, the limiting assembly 13 includes a nail seat 2, which is threadedly connected to the mounting hole 12, a connecting block 21 is fixedly connected to the nail seat 2, a screw 22 is threadedly connected to the connecting block 21, a column head 23 is provided on the screw 22, a groove 24 is formed on the column head 23, a recessed area is formed in the recessed area, and the edge of the recessed area is rounded.

[0035] Furthermore, in the limiting assembly 13, the lower end of the nail seat 2 is a threaded structure, and the nail seat 2 and the mounting hole 12 are plugged in and can be rotated.

The screw rod 22 and the connecting block 21 are threadedly driven to drive the column head 23 to move, so that the column head 23 can be tightly pressed against the metal bracket. The edge of the groove 24 at the end of the column head 23 is set as a rounded structure, so that when the column head 23 is against the smooth end surface, the column head 23 is deformed and fits the bracket more closely, and the setting of the recessed area can adapt to metal brackets of more shapes.

[0036] Specifically, the clamping assembly 14 includes a clamping body 3, the clamping body 3 is fixedly connected to the mounting hole 12, a sliding hole 31 is opened on the clamping body 3, a push plate 34 is provided on the clamping body 3, a slide rod 32 is provided on the push plate 34, and the slide rod 32 is plugged into the slide hole 31;

[0038] Specifically, a stud 4 is fixedly connected to the clamp body 3, a pressure plate 41 is sleeved on the stud 4, a second spring 42 is sleeved on the stud 4, one end of the second spring 42 is in contact with the pressure plate 41, and the other end of the second spring 42 is fixedly connected to the stud 4, an adjusting member 43 is threadedly connected to the stud 4, and the adjusting member 43 is in contact with the upper end of the pressure plate 41, a fixing column 47 is provided on the clamp body 3, a guide column 48 is threadedly connected to the pressure plate 41, and the guide column 48 is slidably connected to the clamp body 3, a third spring 49 is provided between the fixing column 47 and the guide column 48, one end of the third spring 49 is fixedly connected to the fixing column 47, and the other end of the third spring 49 is fixedly connected to the guide column 48;

[0039] Specifically, a handle 44 is provided on the adjusting member 43 , a convex plate 45 is fixedly connected to the adjusting member 43 , a convex block 46 is provided on the pressing plate 41 , and the convex plate 45 drives the pressing plate 41 to move by moving the convex block 46 .

[0040] Furthermore, the push plate 34 is aligned with the metal bracket, and the metal bracket is pressed by the push plate 34 to achieve a limiting effect, and the push plate 34 is forced to drive the slide bar 32 to move inside the slide hole 31, and the first spring 33 is compressed and exerts force to push the push plate 34 outward, thereby achieving the limiting effect on the metal bracket;

[0041] Furthermore, when in use, the clamp body 3 is fixed to the support plate 11, and the adjusting member 43 is rotated, so that the adjusting member 43 drives the convex plate 45 to rotate, and the convex plate 45 contacts the convex block 46, so that the convex block 46 drives the pressing plate 41 to move, and the adjusting member 43 is connected to the stud 4 through a thread, and when the adjusting member 43 rotates, the position of the adjusting member 43 decreases, thereby driving the end position of the pressing plate 41 to decrease and press on the metal bracket, thereby limiting the metal bracket;

[0042] It should be noted that when the adjusting member 43 rotates, the protrusion 46 moves due to the force of the protruding plate 45, and the pressure plate 41 also moves accordingly, driving the guide column 48 to move on the clamp body 3, and at the same time pulling the third spring 49. When the protruding plate 45 rotates to the opposite position, the third spring 49 uses the elastic force to move the guide column 48 in the direction of the fixed column 47, thereby returning the pressure plate 41 to its original position.

[0043] Working principle: In the limiting component 13, the lower end of the nail seat 2 is a threaded structure, and the nail seat 2 and the mounting hole 12 are plugged in and can be rotated. After the nail seat 2 is inserted into the mounting hole 12, the angle is adjusted, and then the nail seat 2 and the support plate 11 are fixed by the nut, and the screw rod 22 is rotated. The screw rod 22 and the connecting block 21 are threadedly driven to drive the column head 23 to move, so that the column head 23 can be tightly pressed against the metal bracket. The edge of the groove 24 at the end of the column head 23 is set as a rounded structure, so that when the column head 23 is against the smooth end surface, the column head 23 is deformed and fits the bracket more closely, and the setting of the recessed area can adapt to metal brackets of more shapes.
