Description

Technical Field

[0001] This utility model relates to the field of steel structure frame technology, and specifically to a steel structure frame. Background Technology

[0002] Steel frame structures are widely used in construction, warehousing, equipment support and other fields due to their advantages such as high strength, structural stability and convenient construction.

[0003] Traditional steel frame structures are mostly fixed, with their internal space division and support positions typically non-adjustable, limiting their applicability and flexibility. In practical applications, it is often necessary to adjust the positions of the load-bearing components inside the frame according to different usage requirements, such as supporting equipment or goods of different sizes. In existing technologies, achieving position adjustment usually requires re-cutting and welding the frame, which is not only cumbersome and inefficient but also compromises the overall structural strength, affecting its safety and service life. Therefore, there is an urgent need for a steel frame structure that allows for convenient and quick adjustment of the internal load-bearing component positions while ensuring structural stability and overall strength. Utility Model Content

[0004] The purpose of this utility model is to provide a steel structure frame to solve the problems of inconvenient adjustment of the position of the load-bearing components and poor flexibility in the existing steel structure frame.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: A steel structure frame includes a square frame. Each of the two opposite outer walls of the square frame has a strip-shaped hole extending through its corresponding inner wall. The square frame contains a plurality of slides that can be adjusted laterally. Each of the slides has a slider fixedly installed at both ends, which is slidably installed in the corresponding strip-shaped hole. A carrier plate is fixedly installed on the top of the slides. Side plates are detachably installed on both sides of the square frame. Each of the two side plates has an extrusion strip fixedly installed on one side facing each other, which is adapted to be inserted into the strip-shaped hole and presses against the slider.

[0006] As a further improvement of this utility model, two support blocks are vertically fixed between each of the several carrier plates and the corresponding slide, and each of the several carrier plates has a through-hole.

[0007] As a further improvement of this utility model, screws are threaded into both side plates, and four screws are respectively threaded into the two opposite outer walls of the square frame.

[0008] As a further improvement of this utility model, hoisting components are installed at both ends of the square frame.

[0009] As a further improvement of this utility model, both of the lifting components include an L-shaped connecting rod that is vertically fixed to the end of the square frame, and also include hanging plates located on both sides of the square frame.

[0010] As a further improvement of this utility model, the two hanging plates are respectively vertically fixedly connected to two corresponding L-shaped connecting rods, and two through holes are opened through the two hanging plates.

[0011] Compared with the prior art, the beneficial effects of this utility model are: 1. This utility model, through the cooperative design of the sliding base and the strip hole of the square frame, can achieve stepless horizontal adjustment without damaging the original structure of the frame. It can adapt to the placement needs of equipment or goods of different sizes, improve the applicability and scenario flexibility of the frame, and meet the diverse usage needs in practical applications. 2. The adjustment process does not require complicated tools or professional skills. Simply loosen the screws on the side plate and remove the side plate to release the slider lock. After pushing the carrier plate or slide block to adjust to the target position, reinstall the side plate and tighten the screws to complete the fixation. The entire operation is simple and easy to understand, avoiding the cumbersome process and long operation time of traditional cutting and welding methods, improving the efficiency of position adjustment and reducing labor and time costs.

[0015] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0016] The present invention will be further described below with reference to the embodiments.

[0017] Example 1 Reference Figure 1-4 This is the first embodiment of the present utility model, which discloses a steel structure frame provided by the utility model, including a square frame 1. The square frame 1 is welded from steel profiles and has sufficient structural strength. On the two sets of opposite outer side walls of the square frame 1, there are elongated strip holes 11 penetrating through its inner side walls. Inside the square frame 1, there are several sliding seats 2 whose positions can be adjusted along the extension direction (i.e., laterally) of the strip holes 11.

[0018] The slide block 2 is a long strip-shaped plate structure. Its two ends along its length are supported and guided by the sliders 21. The bottom of the slide block 2 maintains a small gap with the inner bottom surface of the square frame 1 so that it does not rub against the frame during adjustment and ensures smooth sliding. Alternatively, the bottom of the slide block 2 is provided with a wear-resistant pad with a low coefficient of friction, so that it can slide smoothly on the inner bottom surface of the square frame 1. Each slide block 2 has a slider 21 fixedly installed at both ends. These sliders 21 are slidably installed in the corresponding strip holes 11, so that the slide block 2 can drive the slider 21 to slide along the strip holes 11. Each slide 2 has a support plate 22 for supporting equipment or goods mounted on its top by welding or other fixing methods. To enhance the support strength of the support plate 22 and reduce its weight, two support blocks 23 are vertically fixed between the support plate 22 and the slide 2. At the same time, another mounting hole 24 is opened through the center of the support plate 22. This mounting hole 24 can be used for weight reduction, as well as for passing through pipelines or for auxiliary fixing. Side plates 3 are detachably mounted on both sides of the square frame 1 using screws 32. Extrusion strips 31 are fixedly mounted on the opposing side (i.e., the inner side) of each of the two side plates 3. The locking mechanism of this invention is based on a double-safety principle. First, by tightening the screw 32, the side plate 3 drives the extrusion strip 31 to generate a strong lateral preload, providing initial static friction locking for the slider 21. Second, and more importantly, when the carrier plate 22 bears a vertical load, this load is transmitted to the slider 21 through the slide block 2 and ultimately acts on the lower edge of the strip hole 11 of the square frame 1. This vertical force significantly increases the normal pressure between the contact surface of the slider 21 and the strip hole 11, thereby generating sliding friction resistance proportional to the load according to the tribological principle. This friction force dynamically generated by the working load, combined with the static friction force of the lateral extrusion, constitutes an extremely reliable locking system with a self-reinforcing effect, effectively preventing any displacement of the slide block 2 under heavy load conditions and ensuring the stable load-bearing capacity of the entire frame. When the side plate 3 is fastened to the square frame 1 by screws 32, the extrusion strip 31 will be inserted into the corresponding slot 11 and will form an extrusion contact with the sides of all the sliders 21 in the slot 11. The friction generated by this extrusion can effectively lock the sliders 21 and the slide block 2 in the current position and prevent them from moving under load.

[0019] Lifting assemblies are also installed at both ends of the square frame 1 to facilitate the lifting of the frame. Each lifting assembly includes two L-shaped connecting rods 41 that are vertically fixed to the ends of the square frame 1, and two lifting plates 42 located on both sides of the square frame 1. The two lifting plates 42 are vertically fixed to the ends of the two L-shaped connecting rods 41 on the corresponding side, and each lifting plate 42 has two through holes 43 for connecting hooks or ropes.

[0020] The working process of a steel structure frame is as follows: First, when it is necessary to adjust the position of the equipment or goods carried on the carrier plate 22, the operator uses a tool to loosen the screws 32 on the side plates 3 and remove the side plates 3 from the square frame 1. At this time, the compression strips 31 fixed to the inside of the side plates 3 will exit from the strip holes 11 on the side wall of the square frame 1, releasing the compression and locking effect on the slider 21.

[0021] The operator can then push the carrier plate 22 laterally or directly push the slide block 2, allowing the sliders 21 at both ends of the slide block 2 to slide freely along the slots 11 on the square frame 1. Due to the length limitation of the slots 11, the slide block 2 can be infinitely adjusted within the width of the square frame 1. After adjusting the carrier plate 22 to the desired lateral position, the operator reinstalls the side plates 3 and secures them to the outer wall of the square frame 1 with screws 32. During this process, the pressing strips 31 on the side plates 3 are inserted into the slots 11 again and form a tight pressing contact with the sides of all the sliders 21, using the generated friction to firmly lock each slider 21 in the current working position.

[0022] Under load, the weight of the equipment or goods is transferred to the slide 2 via the carrier plate 22. This vertical load produces two key effects: first, it is distributed and supported by the structure of the support block 23 and the slide 2; second, the load causes the slider 21 to press tightly against the bearing edge of the slot 11. According to the principle of tribology, this pressure is converted into a huge static friction force. This friction force, together with the lateral locking force provided by the side plate 3 through the extrusion strip 31, ensures the absolute fixation of the position of the slide 2, and ultimately the force is stably transferred to the square frame 1 through the slider 21. The weight of the equipment or goods is transferred to the slide block 2 via the carrier plate 22, and after the structural stability is enhanced by the support block 23, it is finally transferred to the square frame 1 via the slider 21. The mounting hole 24 opened in the center of the carrier plate 22 can reduce the overall weight and provide a passage for pipeline layout.

[0023] When the frame needs to be hoisted, the operator passes the sling or hook through the through hole 43 on the hoisting plate 42 and uses the hoisting assembly consisting of the L-shaped connecting rod 41 fixed to the end of the square frame 1 and the hoisting plate 42 to safely carry out the lifting and transportation operation. Throughout the process, the structural stability of the frame is fully guaranteed by the cooperation between the slider 21 and the strip hole 11, the locking effect of the compression strip 31, and the strengthening effect of the support block 23.

[0024] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions will not cause the essence of the corresponding technical solutions to deviate from the protection scope of the technical solutions of the embodiments of this utility model.
