Abstract
Description
Technical Field
[0001] This utility model relates to the field of steel structure construction technology, and in particular to a support device for the construction of steel structure workshops. Background Technology
[0002] In the construction of steel structure workshops, it is often necessary to vertically weld square steel to form the supporting frame at the top. Traditional construction methods typically involve using hoisting equipment (such as cranes or gantry cranes) to suspend the square steel to be welded to a predetermined position, whereby welders then perform the welding work. However, this method has the following problems: because the square steel is only suspended and fixed by the hoisting equipment, it is easily affected by wind, equipment vibration, or human operation during the welding process, causing it to sway and resulting in welding position deviation, affecting the welding quality. Furthermore, the hoisting equipment needs to be continuously kept suspended, requiring repeated adjustments to the position of the square steel during the welding process, which not only consumes equipment resources but also prolongs the construction period.
[0003] Therefore, there is an urgent need for a support device for steel structure factory construction that can provide temporary support for the square steel to be welded during welding, ensure stability during the welding process, and guarantee welding quality and efficiency. Utility Model Content
[0004] The purpose of this utility model is to provide a support device for the construction of steel structure workshops, which can provide temporary support for the square steel to be welded, ensure stability during the welding process, and ensure welding quality and efficiency.
[0005] The present invention adopts the following technical solution:
[0006] A support device for steel structure factory construction includes a lower support part, with an upper support part connected to both ends of the lower support part by connecting rods. A limit rod is provided at the end of the upper support part away from the connecting rods, and a positioning part is provided at the bottom of the limit rod. During operation, the upper support part is placed on the top of a square steel, the limit rod and the connecting rod are located on both sides of the square steel, the positioning part is located at the bottom of the square steel, and the square steel to be welded is placed on the lower support part.
[0007] Preferably, both the lower support portion and the upper support portion are plate-shaped structures.
[0008] Preferably, the connecting rod is a threaded rod, and an adjustment hole is provided through the upper support for the threaded rod to pass through. The connecting rod passes through the adjustment hole and is connected to an adjustment nut.
[0009] Preferably, the positioning part is a plate-shaped structure.
[0010] Preferably, the limiting rod is rotatably mounted on the upper support portion.
[0011] Preferably, the limiting rod is elastically disposed on the upper support portion.
[0012] Preferably, a spring is provided at the top of the upper support portion, and the top of the limiting rod passes through the spring and is rotatably connected to a support sleeve, with the top of the spring being fixedly connected to the bottom of the support sleeve.
[0013] Preferably, the top end of the limiting rod protrudes from the support sleeve and extends upward.
[0014] Preferably, the limiting rod and the support sleeve are rotatably connected by a bearing.
[0015] Compared with the prior art, the beneficial effects of this utility model are as follows: This utility model forms a frame structure with an open bottom by cooperating with the upper support part and the connecting rods and limiting rods on both sides. The frame structure is fitted onto the installed square steel, which can provide stable support for the lower support part. Then, the positioning part is placed at the bottom of the installed square steel to complete the positioning of the frame structure. The square steel to be welded can then be placed on the lower support part, which provides stable support for one end of the square steel to be welded, greatly ensuring the quality and efficiency of welding. After welding is completed, the positioning part is removed from the bottom of the square steel, and the entire device can be removed. The device is reusable, has a high utilization rate, and low operating cost. Attached Figure Description
[0016] Figure 1 This is a schematic diagram of the structure of an embodiment of this application;
[0017] Figure 2 This is a usage state diagram of an embodiment of this application. Detailed Implementation
[0018] The present invention will now be described clearly and completely with reference to the accompanying drawings and embodiments:
[0019] like Figures 1 to 2As shown, the present invention discloses a support device for steel structure factory construction, comprising a lower support part 1. Both ends of the top of the lower support part 1 are connected to an upper support part 3 via connecting rods 2. The upper support part 3 is arranged perpendicularly to the lower support part 1. A limit rod 4 is provided at the end of the upper support part 3 away from the connecting rod 2, and a positioning part 5 is provided at the bottom of the limit rod 4. During operation, the upper support part 3 is placed on top of the installed square steel 6, with the limit rod 4 and connecting rod 2 located on either side of the square steel 6. The position of the upper support part 3 is adjusted so that the positioning part 5 is located at the bottom of the square steel 6, preventing the end of the connecting rod 2 from tilting when the square steel 6 to be welded is placed on the lower support part 1. Finally, one end of the square steel 6 to be welded is placed on the lower support part 1. Because the lower support part 1 provides stable support for the welding end of the square steel 6 to be welded, it greatly ensures welding quality and efficiency, while reducing the long-term occupation of lifting equipment. In this embodiment, the lower support part 1, the upper support part 3, and the positioning part 5 are all plate-shaped structures to increase the contact area with the square steel 6 and improve the support or positioning effect.
[0020] Furthermore, the connecting rod 2 is a threaded rod, and an adjustment hole for the threaded rod to pass through is provided on the upper support part 3. The connecting rod 2 passes through the adjustment hole and is connected to the adjustment nut 7. This arrangement allows the height of the lower support part 1 to be adjusted, thereby meeting the welding requirements of the square steel 6 at different points and enhancing the practicality of this utility model.
[0021] Furthermore, in this example, the limiting rod 4 is rotatably mounted on the upper support part 3. Rotating the limiting rod 4 controls the movement of the positioning part 5 under the square steel 6, facilitating the installation and disassembly of the entire support device. Preferably, the limiting rod 4 is elastically mounted on the upper support part 3, so that pressing down the limiting rod 4 pushes the positioning part 5 downwards, preventing the positioning plate from contacting the bottom surface of the square steel 6 when moving in and out, reducing wear between them. Simultaneously, the elastic restoring force ensures the positioning part 5 is tightly pressed against the bottom of the square steel 6, achieving a stable connection between the support device and the square steel 6. Specifically, a spring 8 is provided at the top of the upper support part 3. The top of the limiting rod 4 passes through the spring 8 and is rotatably connected to a support sleeve 9 via a bearing. The top of the spring 8 is fixedly connected to the bottom of the support sleeve 9. During operation, pressing the support sleeve 9 causes the limiting rod 4 to move downwards, thereby pushing the positioning part 5 downwards. Then, rotating the limiting rod 4 moves the positioning part 5 to the bottom of the square steel 6. Finally, releasing the pressure on the support sleeve 9 allows the positioning part 5 to firmly abut against the bottom of the square steel 6 under the restoring force of the spring 8. Preferably, the top end of the limiting rod 4 protrudes from the support sleeve 9 and extends upwards to facilitate rotational adjustment of the limiting rod 4.
[0022] In use, the upper support 3 is placed on the installed square steel 6, then the support sleeve 9 is pressed down, pushing the limiting rod 4 and the positioning part 5 downward. When the positioning part 5 moves to the bottom of the square steel 6, the limiting rod 4 is rotated to move the positioning part 5 into the bottom of the square steel 6. Then the pressure applied to the support is released, and under the restoring force of the spring 8, the positioning part 5 tightly abuts against the bottom of the square steel 6, completing the installation of the entire device. Finally, the square steel 6 to be welded is placed on the lower support 1 for welding. After welding is completed, the support sleeve 9 is pressed down, and the limiting rod 4 is rotated to control the positioning part 5 to move out from the bottom of the square steel 6, and the device can be removed.
