Description

Technical Field

[0001] This invention relates to the field of auxiliary structure technology for scaffolding support frames, and specifically to a beam support device. Background Technology

[0002] The popularization of prefabricated construction has led to the gradual replacement of traditional steel pipe fastener support systems with disc-lock scaffolds. The use of beam supports is an important way to reduce the amount of support used and avoid back jacking under the beams. It is especially suitable for high formwork with an erection height of over 8m, which can increase the spacing between local uprights and significantly reduce the steel content.

[0003] Existing support beams mostly use aluminum beams and end plates welded together, or are connected using fixed sleeve bolts, which fixes the clearance between the double support beams. However, due to welding, the double aluminum beams are not reusable and have disadvantages such as large size, inconvenience in transportation, storage, and on-site use. In addition, because the clearance of existing support beams is fixed, they are only suitable for one type of upright system, and the only difference between the two specifications is the clearance, which increases the difficulty of differentiation and use. At the same time, during on-site use, construction personnel have difficulty distinguishing between them, which can easily lead to confusion, low work efficiency, and even the mixing of support beams adapted to the 60 system with uprights adapted to the 48 system. This results in greater swaying at the top of the support system, easy slippage, and compromised safety.

[0004] Therefore, it is necessary to design a beam support device to solve the aforementioned technical problems. Summary of the Invention

[0005] In view of the above-mentioned problems existing in the prior art, the aim is to provide a beam support device.

[0006] The specific technical solution is as follows:

[0007] A beam support device mainly includes: channel steel and anchoring connectors;

[0008] Two channel steels are provided, which are arranged opposite to each other. Several anchoring connectors are provided, with both ends of the anchoring connectors passing through the two channel steels respectively. The anchoring connectors are provided with at least two levels of stepped surfaces. By abutting the channel steels with different levels of stepped surfaces, the net distance between the two channel steels is adjustable.

[0009] The aforementioned beam support device also has the following feature: the anchoring connector includes a body and two threaded sections disposed at both ends of the body, and both ends of the body are provided with stepped grooves.

[0010] The aforementioned beam support device also has the following feature: each end of the main body is provided with two stepped grooves, the two stepped grooves located at the same end are arranged opposite to each other, the radial stepped surface of the two stepped grooves located at the same end is the first-level stepped surface, and the end face of each end of the main body is the second-level stepped surface.

[0011] The aforementioned beam support device also has the feature that the threaded section extends out of one end of the channel steel and is fastened by a nut.

[0012] The aforementioned beam support device also includes an upright, a first connecting plate, and a tie rod. The first connecting plate is disposed on two of the channel steels, the upright passes through the first connecting plate, and each end of the tie rod is connected to one of the first connecting plates.

[0013] The aforementioned beam support device also features that the two ends of the tie rod are provided with slots, and the first connecting plate is clamped in the slot and connected by a pin.

[0014] The aforementioned beam support device also includes a column and a second connecting plate, the second connecting plate being located below the two channel steels, and the column passing through the second connecting plate.

[0015] The positive effects of the above technical solution are:

[0016] The present invention provides a beam support device, wherein the anchoring connector is provided with a stepped groove. By abutting different levels of stepped surfaces against the channel steel, the clear distance between the two channel steels can be adjusted, making the clear distance between the two channel steels adjustable to meet various different needs. The anchoring connector and the channel steel are detachable and can be adjusted randomly on site, making installation convenient and facilitating transportation and storage.

[0026] Please see Figures 1 to 5 The present invention discloses a beam support device, comprising: a channel steel 1 and an anchoring connector 2;

[0027] There are two channel steels 1, which are set opposite to each other. There are several anchoring connectors 2, with both ends of the anchoring connectors 2 passing through the two channel steels 1 respectively. The anchoring connectors 2 are provided with at least two levels of stepped surfaces. By abutting the channel steels with different levels of stepped surfaces, the net distance between the two channel steels 1 can be adjusted.

[0028] Optionally, the channel steel 1 is a "]" shaped steel, and two channel steels 1 are arranged opposite to each other to form a "][" shaped structure. The channel steel 1 includes two parallel plates and a connecting plate. The two ends of the connecting plate are respectively connected to the two parallel plates to form a "]" shaped structure, and the connecting plate is the web of the channel steel.

[0029] Optionally, in this embodiment, the anchoring connector 2 includes a body 21 and two threaded sections 22 disposed at both ends of the body 21, and both ends of the body 21 are provided with stepped grooves 211. Figure 3 As shown, each end of the body 21 is provided with two stepped grooves 211. The two stepped grooves 211 located at the same end are arranged opposite to each other. The radial stepped surfaces of the two stepped grooves 211 located at the same end are first-level stepped surfaces 201, and the end face of each end of the body 21 is a second-level stepped surface 202. The level of the first-level stepped surface 201 and the second-level stepped surface 202 is determined by the position of the stepped surfaces in the axial direction of the body 21. If the first-level stepped surface 201 and the second-level stepped surface 202 are of different levels, their positions in the axial direction of the body 21 will be different. There are two inner radial surfaces of the two stepped grooves 211 at the same end. The two inner radial surfaces are in the same position in the axial direction of the body 21, so they are at the same level. In this embodiment, the end face of each end of the body 21, the two stepped grooves 211 at the same end, and the body 21 form a convex structure. A total of two convex structures can be formed at both ends of the body 21. Optionally, in this embodiment, the body 21 is a square structure; in other embodiments, the body 21 can be cylindrical.

[0030] Optionally, in some other embodiments, the stepped surface may have more than two levels, such as three, four, or even more. Taking three levels as an example, a stepped groove perpendicular to the aforementioned stepped groove 211 can be provided on the end face of each end of the body 21. The stepped groove and the stepped groove 211 are similar in shape, but different in direction and position in the axial direction of the body 21. The stepped groove is located between the stepped groove 211 and the end face of the body 21. If more than four levels of stepped surface are provided, it is only necessary to repeatedly alternate the stepped groove 211 and the stepped groove. Moreover, the maximum outer diameter of the stepped surface closer to the end face of the body 21 is smaller.

[0031] Furthermore, the threaded section 22 extends out of one end of the channel steel 1 and is fastened by the nut 3.

[0032] The web of the channel steel is provided with assembly holes. During assembly, the threaded section 22 of the anchoring connector 2 is passed through the assembly holes of the channel steel web. However, how much it can pass through depends on the size of the assembly hole. Therefore, the size of the assembly hole is set according to the outer diameter of the step surface that cannot be passed through. It needs to be smaller than the maximum outer diameter of the step surface that cannot be passed through, so that the channel steel web and the target step surface of the anchoring connector 2 abut against each other to achieve the required clearance.

[0033] Optionally, in this embodiment, two anchoring connectors 1 are provided; in other embodiments, more may be provided.

[0034] Furthermore, it also includes an upright 4, a first connecting plate 51, and a tie rod 6. The first connecting plate 51 is mounted on two channel steels 1, the upright 4 passes through the first connecting plate 51, and each end of the tie rod 6 is connected to a first connecting plate 51. Specifically, there are two first connecting plates 51, each mounted on two channel steels 1. One upright 4 passes through one first connecting plate 51, and both ends of the tie rod 6 are provided with slots. Part of the first connecting plate 51 is clamped in the slot and connected by a pin 7. The slot is a conventional technical means in the field of scaffolding and is existing technology, so it will not be described in detail here.

[0035] Furthermore, it also includes a column 8 and a second connecting plate 52, the second connecting plate 52 being located below the two channel steels 1, and the column 8 passing through the second connecting plate 52.

[0036] Specifically, in this embodiment, the distance between the two channel steels 1 is less than the diameter of the first connecting plate 51 and the second connecting plate 52. The two ends of the first connecting plate 51 are respectively connected to the upper surfaces of the two channel steels 1, and the two ends of the second connecting plate 52 are respectively connected to the lower surfaces of the two channel steels 1. The column 8 passes through the space between the two channel steels 1.

[0037] The present invention provides a beam support device, wherein the anchoring connector 2 is provided with a stepped groove 211. By abutting different levels of stepped surfaces with channel steel 1, the net distance between the two channel steel 1 can be adjusted, so that the net distance between the two channel steel 1 is adjustable to meet various different needs. The anchoring connector 2 and the channel steel 1 are detachable and can be adjusted randomly on site. It is easy to install, transport and store.

[0038] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0039] The above embodiments merely illustrate several implementation methods of the present invention, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of the present invention. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these all fall within the protection scope of the present invention. Therefore, the protection scope of this patent should be determined by the appended claims.
