It is the process of building various types of buildings, or the process of turning the lines on the design drawings into physical objects at a designated location. It includes foundation construction, main structure construction, roof construction, decoration construction, etc. The place where construction work is carried out is called the "construction site" or "construction site".

[0003] Medium and large-sized buildings in cities often use steel space frames. Steel space frames are particularly suitable for building buildings with irregular shapes, which can highlight the building's appearance. Common examples include shopping malls, stadiums, conference centers, and office buildings.

[0004] When welding one steel structure to another in mid-air, a clamping device is needed to fix the position between the two steel structures. However, in the existing technology, most clamping devices require turning a bolt first to adjust the angle of the clamping device to the appropriate position, and then turning the bolt again to fix the angle of the clamping device. This is not only cumbersome to operate, but also affects the effectiveness of the clamping device, thus affecting the efficiency of building construction. In view of this, we propose a clamping device for welding steel structures in building construction. Utility Model Content

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0014] 1. This utility model, by setting a limiting component, allows for the adjustment of the angle between support arm A and support arm B. First, pulling the four reset rods causes the movable block to slide within the movable and fixed grooves, compressing the spring until the movable block disengages from the fixed groove. Then, rotating support arm B to the appropriate angle, releasing the pull block causes the spring to extend, allowing the movable block to slide in the opposite direction within the movable groove. This causes the four reset rods to move in the opposite direction until the movable block engages with the fixed groove. This completes the adjustment and fixing of the angle between support arm A and support arm B. This utility model facilitates the adjustment and fixing of the angle between support arm A and support arm B, improving the efficiency of construction.

[0015] 2. By setting up a pull plate and a pull block, the operator only needs to pull the pull block to move the pull plate, which in turn moves the four reset rods synchronously. This avoids the need to pull the four reset rods separately, thus avoiding affecting the effectiveness of the invention. The pull block is set in a U-shape to facilitate the operator's pulling of the pull block.

[0016] 3. By setting a positioning port in an arc shape, the movable block slides into the fixing groove under the guidance of the positioning port when it comes into contact with the positioning port, which facilitates the insertion of the movable block into the fixing groove and thus improves the practicality of the present invention.

[0027] The present invention will be further described below with reference to the accompanying drawings and embodiments:

[0028] Example 1: A steel structure welding clamping device for building construction, see [link / reference] Figures 1 to 5 The device includes a clamping component 1 and a limiting component 2; wherein, the clamping component 1 includes a support arm A101, a support arm B102 and a fixing component 103; the support arm A101 is rotatably connected to the support arm B102 through a rotating shaft, and the two fixing components 103 are fixed at opposite ends of the support arm A101 and the support arm B102.

[0029] like Figure 1-5 As shown, in this embodiment, the limiting component 2, during use, allows for convenient adjustment and fixation of the angle between support arm A101 and support arm B102. Specifically, the limiting component 2 includes a movable groove 201, a spring 202, a movable block 203, a reset rod 204, and a fixing groove 205. Four movable grooves 201 are arranged in a circular array at the end of support arm A101 away from the fixing member 103. The spring 202 is disposed in the movable groove 201, and one end of the spring 202 is flush with the inner wall of the movable groove 201. Fixed connection; the movable block 203 is slidably disposed in the movable groove 201, the movable block 203 is fixedly connected to the other end of the spring 202, and the end of the movable block 203 extends to the outside through the movable groove 201; the reset rod 204 is fixedly disposed on the side of the movable block 203 near the spring 202, and the end of the reset rod 204 extends to the outside through the movable groove 201; the support arm B102 has twelve fixed grooves 205 arranged in a ring array at the end away from the fixed member 103; wherein the movable block 203 is inserted into the fixed groove 205. This invention, by setting a limiting component 2, allows for the adjustment of the angle between support arm A101 and support arm B102. First, pulling the four reset rods 204 causes them to move, allowing the movable block 203 to slide within the movable groove 201 and the fixed groove 205. This causes the spring 202 to contract under pressure until the movable block 203 disengages from the fixed groove 205. Then, rotating support arm B102 to the appropriate angle, releasing the pull block 302 causes the spring 202 to extend, allowing the movable block 203 to slide in the opposite direction within the movable groove 201. This causes the four reset rods 204 to move in opposite directions until the movable block 203 engages with the fixed groove 205. This completes the adjustment and fixing of the angle between support arm A101 and support arm B102. This invention facilitates the adjustment and fixing of the angle between support arm A101 and support arm B102, improving the efficiency of construction.

[0030] Specifically, the movable block 203 has a fan-shaped structure. By setting the movable block 203 into a fan-shaped structure, this utility model facilitates the insertion and fixing of the movable block 203 into the next fixing slot 205 when it rotates through the support arm A101 and the support arm B102.

[0031] Furthermore, it also includes a pulling component 3; the pulling component 3 is arranged on the reset rod 204; wherein, the pulling component 3 includes a pull plate 301 and a pull block 302; the pull plate 301 is located on one side of the support arm A101, and the side of the pull plate 301 near the support arm A101 is fixedly connected to the end of several reset rods 204 away from the movable block 203; the pull block 302 is fixedly located on the side of the pull plate 301 away from the support arm A101; wherein, the pull block 302 has a U-shaped structure. By setting the pull plate 301 and the pull block 302, the operator only needs to pull the pull block 302 to move the pull plate 301, which can drive the four reset rods 204 to move synchronously, avoiding the need to pull the four reset rods 204 separately, thus affecting the use effect of the present invention. The pull block 302 is set in a U-shaped structure to facilitate the operator to pull the pull block 302.

[0032] Furthermore, it also includes a positioning port 4; the positioning port 4 is arranged at the port of the fixed groove 205; wherein, the positioning port 4 has an arc-shaped structure; when the movable block 203 is inserted into the fixed groove 205, the movable block 203 still contacts the movable groove 201. By setting the positioning port 4 and making the positioning port 4 into an arc-shaped structure, when the movable block 203 contacts the positioning port 4, the movable block 203 will slide into the fixed groove 205 under the guidance of the positioning port 4, which facilitates the insertion of the movable block 203 into the fixed groove 205, thereby improving the practicality of this utility model.

[0033] Working principle: When it is necessary to adjust the angle between support arm A101 and support arm B102, firstly, pull block 302 is pulled, causing pull block 302 to move pull plate 301, which in turn moves the four reset rods 204, causing movable block 203 to slide within movable groove 201 and fixed groove 205. This causes spring 202 to contract under force until movable block 203 disengages from fixed groove 205. At this point, support arm B102 is rotated to the appropriate angle, and then pull block 302 is released, and spring 202 returns to its original position. When the spring 202 is no longer under force, it begins to stretch, causing the movable block 203 to slide in the opposite direction in the movable groove 201. This causes the four reset rods 204 to move in the opposite direction, and the pull plate 301 to drive the pull block 302 to move in the opposite direction. If the movable block 203 contacts the positioning port 4, the movable block 203 will slide into the fixed groove 205 under the guidance of the positioning port 4 until the movable block 203 is inserted into the fixed groove 205. At this point, the adjustment and fixation of the angle between the support arm A101 and the support arm B102 is completed.
