Description

Technical Field

[0001] This utility model relates to the field of supporting steel frame technology, and in particular to an assembled supporting steel frame. Background Technology

[0002] In construction, equipment installation and other scenarios, supporting steel frames are commonly used load-bearing structures to support and fix temporary facilities, equipment or building components. These supporting steel frames need to withstand vertical pressure and lateral impact forces ranging from several tons to tens of tons, depending on the load requirements of different scenarios. Their structural stability is directly related to construction safety, equipment operation accuracy and the installation quality of building components.

[0003] Application No. 202421442064.2 relates to a prefabricated building beam support steel frame, including a support column. A support frame is fixedly installed on the top of the support column, and an auxiliary support mechanism is provided at the bottom of the support column. The auxiliary support mechanism includes a mounting plate, a cavity, a lead screw, a rotating rod, a first gear, a second gear, a threaded sleeve, a first hinge block, a telescopic rod, an adjusting cylinder, a second hinge block, and a base plate. This prefabricated building beam support steel frame, by setting up the auxiliary support mechanism, can provide auxiliary support for the support column. Furthermore, this mechanism can adjust the position of the base plate according to the terrain, offering a wide adjustment range and strong applicability. Turning the handle drives the rotating rod and the first gear to rotate, which in turn drives the second gear and the lead screw to rotate, thereby moving the threaded sleeve on the lead screw. Simultaneously, the depth of the telescopic rod within the adjusting cylinder can be adjusted. By swinging the adjusting cylinder, the base plate can be moved to a suitable support position, thus providing relatively stable support.

[0004] The above-mentioned solution has shortcomings in use. The supporting area of ​​the supporting steel is fixed and cannot be flexibly adjusted according to the actual size of the supported object. When supporting a beam with a large span and a cross-sectional width exceeding the size of the top seat, multiple support frames need to be arranged at intervals along the length of the beam to provide support, which further increases the number of support frames used and the material cost. Therefore, we provide a prefabricated supporting steel frame. Utility Model Content

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0026] First Embodiment As attached Figure 1 With appendix Figure 2As shown: A prefabricated support steel frame includes a support frame 1 and a top-holding assembly 2, which is disposed below the support frame 1 and is used to apply a top-holding force to the support frame 1. The top-holding assembly 2 includes an adjustable top column 201 disposed below the support frame 1. A cross plate 202 is fixedly connected to the top of the adjustable top column 201. The cross plate 202 is connected to the bottom surface of the support frame 1 by two sets of connecting bolts 203. The connecting bolts 203 can firmly connect the support frame 1 and the cross plate 202. A fixing seat 204 is fixedly connected to the bottom of the adjustable top column 201. The fixing seat 204 can fix the adjustable top column 201. By adjusting the adjustable top column 201, the support frame 1 can form a tight contact with the required support beam, thus achieving the top-holding effect.

[0027] The bottom surface of the cross plate 202 is fixedly connected with a ring of inclined plates 205. The bottom end of each inclined plate 205 is connected to the outer surface of the adjustable top column 201. The inclined plates 205 can enhance the supporting effect of the cross plate 202 on the support frame 1. The upper surface of the fixed seat 204 is fixedly connected with a ring of triangular reinforcing blocks 206. One side of each triangular reinforcing block 206 is connected to the outer surface of the adjustable top column 201. The triangular reinforcing blocks 206 can fix the connection between the fixed seat 204 and the adjustable top column 201, further enhancing the stability of the adjustable top column 201.

[0028] Second Embodiment As attached Figure 1 Appendix Figure 3 Appendix Figure 4 Appendix Figure 5 With appendix Figure 6 As shown: The secondary support assembly 3 is disposed on the left and right sides of the support frame 1, including secondary support plates 301 disposed on both sides of the support frame 1 and flush with it, and a connection structure disposed between the secondary support plates 301 and the support frame 1. The connection structure includes two sets of slots 302 opened on the left and right sides of the support frame 1. Each slot 302 has a plate 303 inserted inside it. One end of each plate 303 is connected to one side of the secondary support plate 301. By using the connection between the plate 303 and the slot 302, the secondary support plate 301 can be connected to one side of the support frame 1.

[0029] The connecting structure also includes two sets of sleeve frames 304 fixedly connected to the bottom surface of the support frame 1. Each sleeve frame 304 has an L-shaped plate 305 slidably connected to its inner wall. The top of each L-shaped plate 305 is connected to the bottom surface of the auxiliary support plate 301. Each sleeve frame 304 has a threaded abutment bolt 306 connected to its bottom surface. When the auxiliary support plate 301 is connected to one side of the support frame 1, one end of the L-shaped plate 305 connected to the bottom of the auxiliary support plate 301 will pass through the sleeve frame 304 simultaneously. Then, the abutment bolt 306 on the side wall of the sleeve frame 304 is tightened with a wrench to make its end tightly abut against the L-shaped plate 305 for stability. Each set of L-shaped plates 305 has an X-shaped plate 307 fixedly connected to one side of each other. The X-shaped plate 307 can be used to fasten the connection between the L-shaped plates 305, further improving the strength of the L-shaped plates 305.

[0030] The top support structure located below the secondary support plate 301 includes a top rod 308 fixedly connected to the bottom surface of each L-shaped plate 305. The bottom end of each set of top rods 308 is fixedly connected to a U-shaped frame 309, which is fitted onto the outside of the adjustable top column 201. A support frame 310 is provided below each set of U-shaped frames 309. The inner wall of the support frame 310 is connected to the outer surface of the adjustable top column 201. When the secondary support plate 301 is connected to one side of the support frame 1, the top rods 308 will drive the U-shaped frames 309 to naturally fit onto the outside of the adjustable top column 201 and sit on the support frame 310, which can provide support for the edge of the secondary support plate 301 and further enhance its support effect. The outer surface of each set of top rods 308 is fixedly connected to a reinforcing rod 311, which can be used to connect the top rods 308 to keep them stable.

[0031] Working principle: In use, first place the support frame 1 below the bottom of the beam to be supported, then stabilize it using the fixing seat 204. Next, adjust the adjustable top column 201 to ensure close contact between the support frame 1 and the beam, allowing the support frame 1 to provide stable and even support. When facing a larger beam requiring increased support area, smoothly insert the insert plate 303 on the inner side of the secondary support plate 301 into the slots 302 on both sides of the support frame 1. Simultaneously, one end of the L-shaped plate 305 connected to the bottom of the secondary support plate 301 will... Step through the sleeve frame 304. At this time, the U-shaped frame 309 will naturally fit over the adjustable top column 201 and sit on the support frame 310. Then, use a wrench to tighten the abutment bolts 306 on the side wall of the sleeve frame 304 so that its end is tightly abutted against the L-shaped plate 305 for stability. This ensures that the secondary support plate 301 is stably suspended on both sides of the support frame 1 to support the roof beam. There is no need to increase the number of support frames 1, which further reduces the number of support frames 1 used and the material cost. At the same time, the secondary support plate 301 can be removed to avoid affecting the use.
