Description

Technical Field

[0001] This utility model relates to the field of engineering construction, specifically to a steel beam stacking support frame. Background Technology

[0002] In steel structure construction, large steel beams stacked on-site often lack anti-tipping supports, or are only temporarily propped up using long steel pipes or wooden blocks, resulting in extremely low safety. Currently, there are no products on the market that are suitable for stacking steel beams of different sizes, and that are easy to assemble and disassemble, compact, and easy to transport, such as reusable side support frames. Utility Model Content

[0003] To address the problems existing in the prior art, this utility model provides a steel beam stacking support frame, including a first support rod, a second support rod, a third support rod, and a support member. The top side of the first support rod is hinged to one end of the second support rod, and the other end of the second support rod is hinged to one end of the third support rod relative to the side of the first support rod. The bottom of the first support rod has a mounting portion, and the other end of the third support rod is detachably connected to the mounting portion.

[0004] With the above structure, in the folded state, the third support rod is separated from the mounting part, and the hinged surfaces of the first and second support rods overlap, as do the hinged surfaces of the second and third support rods, meaning the support frame can be folded into a flat state. In the open state, the third support rod connects to the mounting part, and the first, second, and third support rods form a triangle, ensuring stable support.

[0005] The support member is hinged to the side of the first support rod that is hinged to the second support rod and / or the opposite side. A limiting member is provided on the support member to fix the angle of the support member relative to the first support rod. In the folded state, the hinged surfaces of the support member and the first support rod overlap, meaning the support member can also be folded to the plane state when the tripod is folded. In the open state, the support member is located on the side of the first support rod opposite the second support rod, facilitating the support of stacked steel beams.

[0006] Furthermore, there are two first support rods, which are arranged in parallel and share the same mounting part. The second support rod is hinged to the opposite sides of the two first support rods via a hinge shaft, making the whole structure more stable.

[0007] Furthermore, there are two second support rods arranged in parallel. The first connecting part is fixedly connected to the ends of the two second support rods that are hinged to the first support rod. The hinge shaft is located inside the first connecting part. The third support rod is hinged to the opposite sides of the two second support rods, making the whole structure more stable.

[0008] Furthermore, the support member includes a second connecting part and two support plates. The two support plates are arranged in parallel and are respectively hinged to the side of the first support rod hinged to the second support rod and the opposite side. The movable ends of the two support plates are fixedly connected through the second connecting part.

[0009] Furthermore, there are two support members, which are respectively hinged to the two first support rods. The two support members are arranged in parallel, and the movable ends of the two support members are fixedly connected by the second connecting part, making the whole more stable.

[0010] Furthermore, the limiting member includes a third connecting part and several snap-fit ​​parts. The third connecting part has a hinge hole in the middle, and each snap-fit ​​part is located on one side of the third connecting part. At least one support plate has a first snap-fit ​​groove that matches the snap-fit ​​part, and the surface of the first support rod that is hinged to the support plate has a second snap-fit ​​groove that matches the snap-fit ​​part, so that the angle of the support member can be fixed.

[0011] Furthermore, the first or second snap-fit ​​groove has several locking positions relative to the snap-fit ​​part, so that the angle of the support member relative to the first support rod is adjustable.

[0012] Furthermore, the first support rod is provided with several second locking grooves along its length, which facilitates adjusting the position of the support member on the support frame as needed.

[0013] Furthermore, the first support rod, the second support rod, and / or the third support rod include an inner rod, an outer rod, and a connector. The inner rod is nested inside the outer rod. At least one of the inner rod or the outer rod is provided with several connector holes, and the other is provided with at least one matching connector hole. The connector is used to connect to the connector holes on the inner rod and the outer rod, so that the relative positions of the inner rod and the outer rod are fixed. This structure allows the size of the support frame to be adjusted as needed.

[0014] Furthermore, the shortest length of the second support rod is adapted to the shortest length of the first support rod excluding the mounting part, and the shortest length of the third support rod is adapted to the shortest length of the second support rod excluding the first connecting part, so that the support frame can form a compact plane after folding.

[0015] This invention is easy to install and disassemble, has a wide range of applications, and its compact size when folded makes it easy to transport, resulting in a high turnover rate. The support frame structure in this invention is simple, enabling standardized mass production and reducing processing costs. Attached Figure Description

[0023] 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.

[0024] See Figure 1 , Figure 2 The steel beam stacking support frame of this embodiment includes a first support rod 1, a second support rod 2, a third support rod 3, and a support member 4. One side of the top of the first support rod 1 is hinged to one end of the second support rod 2, and the other end of the second support rod 2 is hinged to one end of the third support rod 3, opposite to the side of the first support rod 1. The bottom of the first support rod 1 is provided with a mounting part 5, and the other end of the third support rod 3 is detachably connected to the mounting part 5. (See also...) Figure 3 The mounting part 5 is provided with a connection hole, and the third support rod 3 and the mounting part 5 can be fixedly connected by bolts. The corresponding third support rod 3 is provided with a waist-shaped hole 19 to facilitate connection.

[0025] Preferably, there are two first support rods 1, which are arranged in parallel and share the same mounting part 5. A second support rod 2 is hinged to the facing sides of the two first support rods 1 via a hinge shaft, making the overall structure more stable. When the support rod width is too narrow, the mounting part 5 can be designed to be longer to improve stability. There are also two second support rods 2, which are arranged in parallel and include a first connecting part 6. The first connecting part 6 fixes the ends of the two second support rods 2 that are hinged to the first support rods 1. The hinge shaft is located within the first connecting part 6. A third support rod 3 is hinged to the facing sides of the two second support rods 2, making the overall structure more stable.

[0026] With the above structure, in the folded state, the third support rod 3 is separated from the mounting part 5, and the hinged surfaces of the first support rod 1 and the second support rod 2 overlap, as do the hinged surfaces of the second support rod 2 and the third support rod 3, meaning the support frame can be folded into a flat state. In the open state, the third support rod 3 connects to the mounting part 5, and the first support rod 1, the second support rod 2, and the third support rod 3 form a triangle, ensuring stable support.

[0027] The support member 4 is hinged to the side of the first support rod 1 that is hinged to the second support rod 2, or to the opposite side. It can also be hinged to both the side of the second support rod 2 and the opposite side simultaneously to increase stability. The support member 4 is provided with a limiting member 7, which allows the angle of the support member 4 relative to the first support rod 1 to be fixed. (See also...) Figure 4 In this embodiment, the support member 4 includes a second connecting part 8 and two support plates 9. The two support plates 9 are arranged in parallel and are respectively hinged to the side of the first support rod 1 that is hinged to the second support rod 2 and to the opposite side. The movable ends of the two support plates 9 are fixedly connected through the second connecting part 8. Preferably, there are two support members 4, which are respectively hinged to the two first support rods 1. The two support members 4 are arranged in parallel, and the movable ends of the two support members 4 are fixedly connected through the second connecting part 8, making the whole more stable.

[0028] The limiting member 7 in this embodiment includes a third connecting part 10 and a plurality of snap-fit ​​parts 11. The third connecting part 10 has a hinge hole 12 in the middle, and each snap-fit ​​part 11 is disposed on one side of the third connecting part 10. At least one support plate 9 has a first snap-fit ​​groove 13 adapted to the snap-fit ​​part 11, and the surface of the first support rod 1 that is hinged to the support plate 9 has a second snap-fit ​​groove 14 adapted to the snap-fit ​​part 11, so that the angle of the support member 4 can be fixed. Preferably, the first snap-fit ​​groove 13 or the second snap-fit ​​groove 14 has a plurality of locking positions relative to the snap-fit ​​part 11, so that the angle of the support member 4 relative to the first support rod 1 can be adjusted, or multiple locking positions can be provided on the first snap-fit ​​groove 13 or the second snap-fit ​​groove 14 at the same time to facilitate installation. More preferably, the first support rod 1 has a plurality of second snap-fit ​​grooves 14 along its length direction, so as to facilitate adjustment of the position of the support member 4 on the support frame as needed.

[0029] In the folded state, the hinged surfaces of support member 4 and the first support rod 1 overlap, meaning support member 4 can also be folded to the same planar state as when the tripod is folded. In the open state, support member 4 is located on the side of the first support rod 1 opposite to the second support rod 2, facilitating the support of stacked steel beams.

[0030] In this embodiment, one or any two or three of the first support rod 1, second support rod 2, and third support rod 3 include an inner rod 15, an outer rod 16, and a connector 17. The inner rod 15 is nested within the outer rod 16. The inner rod 15 or the outer rod 16 has several matching connector holes 18. Correspondingly, the outer rod 16 or the inner rod 15 has at least one connector hole 18 to connect the inner rod 15 and the outer rod 16, or several connector holes 18 can be provided on both the inner rod 15 and the outer rod 16 for easy installation. The connector 17 is used to connect to the connector holes 18 on the inner rod 15 and the outer rod 16, fixing the relative positions of the inner rod 15 and the outer rod 16. This structure allows the size of the support frame to be adjusted as needed. In this embodiment, the connector 17 uses a U-bolt to increase connection reliability, requiring two connector holes 18 to mate with the U-bolt. In other embodiments, more nested inner rods 15 and outer rods 16 can be provided, such as a four-layer nesting form, to obtain a wider range of length options or a smaller storage space. Preferably, the shortest length of the second support rod 2 is adapted to the shortest length of the first support rod 1 excluding the mounting part 5, and the shortest length of the third support rod 3 is adapted to the shortest length of the second support rod 2 excluding the first connecting part 6, so that the support frame can form a compact plane after folding, which is convenient for storage and transportation.

[0031] In this embodiment, a usage scenario is provided where the heights of the large steel beams to be stacked in the steel structure project are 1, 1.2, and 1.5 m, respectively, with a maximum flange width of 0.3 m, a maximum beam length of 5 m, and a single beam weight of less than 4 t. The first support rod 1, the second support rod 2, and the third support rod 3 are designed with two telescopic sections, each 1000 mm long, with an opening distance of 8 cm. Each support rod uses a 50 mm × 50 mm × 5 mm square steel pipe with a yield strength ≥ 235 MPa. The support plate 9 and the second connecting part 8 on the support member 4 are made of steel sheets with a thickness of 5 mm, a width of 50 mm, and a length of 35 cm. The U-bolts are M16 × 50 mm high-strength bolts, with dimensions based on the opening distance, a preload torque ≥ 150 N·m, and the nut facing the visible side. The installation part 5 is set to a length of 800 mm to improve lateral stability.

[0032] Effect verification: The support frame is placed at both ends of the steel beam, extending inwards at 1 / 8-1 / 4 of the span, for reference. Figure 5At a height of 1.5m, the lateral bearing capacity of the support frame reaches 30kN (far greater than the overturning moment of a 4t steel beam), with a deformation of ≤2mm; adjustment time is ≤3 minutes / time, and the reusability loss rate is <1% (after 50 disassembly and assembly tests).

[0033] 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.
