Description

Technical Field

[0001] This utility model relates to the field of support frame technology, specifically to an adjustable height assembled support frame. Background Technology

[0002] A support frame is a support device used to support structures, equipment, or objects, keeping them stable and bearing loads. In prefabricated buildings, adjustable support frames are used to precisely position prefabricated components, improving construction accuracy.

[0003] However, existing technologies still have the following problems:

[0004] Existing support frames are mostly inefficient to install and disassemble, and have poor modular adaptability. Most existing technologies use welded or fixed connection structures, which require welding equipment for on-site construction. This is not only time-consuming and labor-intensive, but also poses safety hazards due to high-temperature operations. The installation and disassembly process is cumbersome and difficult to adapt to the rapid construction requirements of prefabricated buildings. At the same time, the low standardization of components and the non-modular design result in large space occupation during transportation and high storage costs. They also cannot be flexibly combined according to the construction scenario. The inefficiency problem is even more prominent in temporary support projects where repeated disassembly and assembly are required.

[0005] Furthermore, most support frames have limited height adjustment capabilities and lack versatility. Traditional support frame height adjustment often relies on customized processing (such as cutting pipes and welding fasteners) or uses a single pin-type structure with coarse adjustment spacing, making it impossible to achieve millimeter-level precise positioning. This makes it difficult to adapt to the formwork support needs of different floor heights (such as basements and standard floors). Due to the limited height adjustment range, when facing complex construction scenarios (such as irregular structures and multi-level working surfaces), it is necessary to customize exclusive support equipment, which leads to increased costs and low equipment reuse rate, which does not conform to the concept of green construction.

[0006] To address the aforementioned problems, the inventors proposed an adjustable-height prefabricated support frame. Utility Model Content

[0007] To address the problems of low installation and disassembly efficiency, poor modular adaptability, limited height adjustment, and insufficient versatility, the purpose of this utility model is to provide an adjustable height prefabricated support frame.

[0008] To solve the above technical problems, the present invention adopts the following technical solution: an adjustable height prefabricated support frame, comprising four legs, with a long support rod detachably mounted on the upper outer side of two legs on one side, and a short support rod detachably mounted on the upper outer side of the two legs on one side. Support angles are detachably mounted at the ends of the long and short support rods. A locking block is symmetrically fixed to the upper surface of each support angle. A locking frame is symmetrically fixed to both sides of the upper surface of the long and short support rods. The locking block is locked within the corresponding locking frame, and the locking frame and the corresponding locking block are connected by bolts. Support plates are symmetrically fixed to both sides of the lower surface of the long and short support rods, and the upper surface of the support plate is movably fitted with the corresponding support angle.

[0009] Preferably, each of the outriggers is bolted to both the long and short support rods with two positioning bolts. The outer surface of the outrigger is symmetrically provided with bolt grooves for use with the positioning bolts. Several bolt grooves are provided on one side of one of the outriggers, and the bolt grooves are distributed at the same vertical spacing.

[0010] Preferably, the outrigger has an "L" shaped cross-section, and the long and short support rods have a "U" shaped cross-section. A side guard plate is welded and fixedly connected to the upper outer side of the outrigger, and a reinforcing diagonal rod is fixedly provided on the inner side of the side guard plate. The upper surface of the reinforcing diagonal rod is fixedly connected to the corresponding long support rod. An outer guard plate is welded and connected to the outer side of the two outriggers on one side, and an inner guard plate is welded and connected to the inner side of the two outriggers on one side. The inner and outer guard plates on one side are connected by bolts. A reinforcing column is provided on the lower side of the long support rod, and the two ends of the reinforcing column are respectively connected to the corresponding outriggers by bolts.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0012] The outriggers and long and short support rods of this invention are connected by bolts and snap-fit ​​structures, eliminating the need for welding. This makes installation and disassembly convenient and shortens the construction cycle. The standardized components facilitate transportation and storage, making them suitable for modular construction (such as temporary supports in prefabricated buildings).

[0013] This utility model, through the equidistant distribution of bolt grooves, allows for precise adjustment of the support height according to actual needs, adapting to different construction scenarios (such as formwork support for different floor heights), avoiding customized processing, and improving the versatility of the equipment.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Example: Figure 1-4 As shown, this utility model provides an adjustable-height prefabricated support frame, including four legs 1. Two legs 1 on one side have a detachable long support rod 2 on their upper outer sides, and two legs 1 on the other side have a detachable short support rod 3 on their upper outer sides. The legs 1 have an "L"-shaped cross-section, while the long and short support rods 2 and 3 have "U"-shaped cross-sections. The four legs 1 serve as the basic support structure of the support frame. The "L"-shaped cross-section provides better lateral stability, preventing lateral deformation of the legs under stress. The "U"-shaped cross-section of the long and short support rods 2 and 3 facilitates connection with the legs 1 and support angles 4, etc. Simultaneously, the "U"-shaped structure effectively disperses pressure and improves load-bearing capacity when subjected to vertical loads. The detachable connection design facilitates transportation, storage, and assembly, making it suitable for rapid assembly and disassembly in different construction scenarios.

[0022] Each support leg 1 is bolted to both the long support rod 2 and the short support rod 3, with two positioning bolts 11. The outer surface of the support leg 1 is symmetrically provided with bolt grooves 12 for use with the positioning bolts 11. Several bolt grooves 12 are provided on one side of one of the support legs 1, and these bolt grooves 12 are distributed at the same vertical spacing. By passing the positioning bolts 11 through the long support rod 2 / short support rod 3 and connecting them to the bolt grooves 12 at different heights on the support leg 1, the height of the long support rod 2 and the short support rod 3 can be adjusted. When it is necessary to adjust the height of the support frame, the positioning bolts 11 are loosened, the long support rod 2 / short support rod 3 is moved to the appropriate bolt groove 12 position, and then the bolts are tightened to complete the precise height adjustment to adapt to different construction height requirements, such as the height changes of the formwork support on different floors.

[0023] The ends of the long support rod 2 and the short support rod 3 are detachably equipped with support angles 4. The upper surface of the support angle 4 is symmetrically fixed with locking blocks 41. The upper surfaces of the long support rod 2 and the short support rod 3 are symmetrically fixed with locking frames 42. The locking blocks 41 are locked in the corresponding locking frames 42, and the locking frames 42 and the corresponding locking blocks 41 are connected by bolts. The lower surfaces of the long support rod 2 and the short support rod 3 are symmetrically fixed with support plates 43, and the upper surface of the support plates 43 is movably fitted with the corresponding support angle 4. As the component that directly bears the external load, the locking design of the locking blocks 41 and the locking frames 42 facilitates quick positioning and initial fixing. Then, the bolts are tightened to form a stable connection. The movable fit between the support plates 43 and the support angle 4 can help to distribute the load and prevent the support angle 4 from tilting or displacing after being stressed. This allows the top load to be evenly transferred to the long support rod 2 and the short support rod 3, and then to the support leg 1, ensuring the stability of the entire support structure.

[0024] A side guard plate 5 is welded and fixedly connected to the upper outer side of the outrigger 1, and a reinforcing diagonal rod 51 is fixedly provided on the inner side of the side guard plate 5. The upper surface of the reinforcing diagonal rod 51 is fixedly connected to the corresponding long support rod 2. The side guard plate 5 is welded to the upper outer side of the outrigger 1 to enhance the lateral rigidity of the outrigger and prevent the outrigger from bending and deforming under force. One end of the reinforcing diagonal rod 51 is connected to the side guard plate 5, and the other end is connected to the long support rod 2 to form a triangular support structure. According to the principle of triangle stability, this structure can effectively disperse the load transmitted from the long support rod 2, enhance the connection strength between the outrigger 1 and the long support rod 2, and improve the ability of the entire support frame to resist lateral and vertical forces.

[0025] The outer sides of the two outriggers 1 on one side are welded together with an outer protective plate 6, and the inner sides of the two outriggers 1 on one side are welded together with an inner protective plate 61. The inner protective plate 61 and the outer protective plate 6 on one side are connected by bolts. The outer protective plate 6 and the inner protective plate 61 are welded to the inner and outer sides of the two outriggers on the same side, connecting the two outriggers into an integral frame structure, which enhances the torsional and deformation resistance of the outrigger assembly. The inner protective plate 61 and the outer protective plate 6 are connected by bolts, which ensures the overall rigidity while facilitating disassembly and maintenance. When one outrigger is subjected to external force, the inner and outer protective plates 6 can work together to bear the force, so that the force is evenly distributed between the two outriggers, improving the overall stability of the support frame.

[0026] A reinforcing column 7 is provided on the lower side of the long support rod 2, and the two ends of the reinforcing column 7 are respectively connected to the corresponding support leg 1 by bolts. The reinforcing column 7 is connected between the lower side of the long support rod 2 and the support leg 1, and plays an auxiliary support role. When the long support rod 2 bears a large vertical load, the reinforcing column 7 can share part of the load and transfer it directly to the support leg 1, reducing the bending stress of the long support rod 2. At the same time, the bolt connection between the reinforcing column 7 and the support leg 1 is convenient for installation and disassembly. It can be added when it is necessary to enhance the load-bearing capacity of the support frame, thereby improving the reliability of the support frame under heavy load conditions.

[0027] Working principle: The outer side of the support leg 1 is provided with several bolt grooves 12 that are equally spaced vertically. The positioning bolts 11 pass through the long support rod 2 and the short support rod 3 and are connected to the bolt grooves 12 at different heights. By changing the installation position of the bolt grooves 12, the height of the long support rod 2 and the short support rod 3 can be adjusted, thereby adjusting the support height of the entire support frame.

[0028] The long support rod 2 and the short support rod 3 are connected to the support leg 1 by bolts. The detachable design facilitates on-site assembly and disassembly. The support angle 4 is engaged with the clip frame 42 on the long support rod 2 and the short support rod 3 by the clip 41 and then fixed with bolts to form a stable top support structure.

[0029] The top load is transferred to the long support rod 2 and the short support rod 3 through the support angle 4, and then to the support leg 1 through the positioning bolt 11; the reinforcing column 7, the side guard plate 5 and the reinforcing diagonal rod 51 enhance the connection rigidity between the support leg 1 and the long support rod 2, while the outer guard plate 6 and the inner guard plate 61 reinforce the integrity of the two support legs to ensure that the load is evenly distributed.

[0030] Obviously, those skilled in the art can make various modifications and variations to this utility model without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of the claims of this utility model and their equivalents, this utility model also intends to include these modifications and variations.
