Abstract
Description
Technical Field
[0001] This utility model relates to the field of engineering support beam technology, specifically to a double-channel steel support beam structure for a basement disc buckle frame with added limiting side wall. Background Technology
[0002] Double-channel steel support beams are an important component of the support frame. Existing double-channel steel support beam structures are referenced below. Figure 5 The structure includes two connecting plates fixedly connected by connecting rods 6 between the two channel steel beams. Each connecting plate is threaded with a top support to support the load. Although the double channel steel support beams reduce the material used in the support frame, the relative position of the two connecting plates needs to be determined by the connecting rods 6, which increases the structural complexity and reduces installation efficiency. Utility Model Content
[0003] To address the aforementioned problems in the prior art, this utility model provides a double-channel steel support beam structure for basement disc buckles with an added limiting side wall, which solves the problem of reduced installation efficiency caused by the use of connecting discs for support in existing double-channel steel support beams.
[0004] To achieve the above objectives, the technical solution adopted by this utility model is as follows:
[0005] A basement disc-lock frame double-channel steel support beam structure with added limiting sidewalls is provided, including two opposing uprights, two transversely arranged channel steel beams fixed between the two uprights, two inverted U-shaped bottom supports on the two channel steel beams, each inverted U-shaped bottom support including a U-shaped plate with an opening that engages with both sides of the two channel steel beams, a sleeve vertically provided in the middle of each U-shaped plate, a threaded post fixedly connected to each sleeve, the top of each threaded post being welded to a top support, and a keel beam supported on the two top supports, with limiting heads provided at both ends of the keel beam.
[0006] In this design, the inverted U-shaped base brackets are directly engaged with the two sides of the double-channel steel beam. This prevents the threaded column from easily wobbling when the keel beam is placed on the top bracket. Compared to the connecting plate in existing technologies, the U-shaped plate of the inverted U-shaped base bracket provides two additional side wall surfaces that can limit movement, making it easier to fix. At the same time, since the keel beam is equipped with limiting heads, the top brackets can be directly located at both ends of the keel beam. The keel beam directly limits the distance between the two inverted U-shaped base brackets, eliminating the need for connecting rods, simplifying the installation steps, and improving construction efficiency.
[0007] Furthermore, both channel steel beams are U-shaped steel beams, and the two channel steel beams are set horizontally with their openings facing away from each other.
[0008] Furthermore, each channel steel beam has multiple equally spaced bolt holes, and two channel steel beams are bolted together through these bolt holes.
[0009] Furthermore, bolts are provided on both sides of each U-shaped plate to connect the two channel steel beams. The bolts between the two channel steel beams not only serve as a connection but also restrict the movement of the U-shaped plate.
[0010] Furthermore, each limiting head includes two limiting plates positioned opposite each other at the ends of the keel beam, with a through groove in the center of each limiting plate for the positioning bolt to pass through. The positioning bolt and limiting plates prevent the keel beam from swaying on the top support. The limiting plate with the through groove in the center uses less material compared to the limiting block of the entire solid structure.
[0011] Furthermore, each limiting plate is a plate structure that appears as a right trapezoid in frontal projection and an isosceles trapezoid in top projection. The top inclined surface and ends of the limiting plate...
[0012] Furthermore, connecting discs for supporting the channel steel beams are welded onto both uprights.
[0013] Furthermore, the length of the keel beam is less than the spacing between the two uprights. This setting of the keel beam length avoids direct collision between the beam end and the upright, reserves space for deformation compensation, and improves the structural safety margin.
[0014] This utility model discloses a double-channel steel support beam structure for a basement disc-lock frame with an added limiting side wall, the beneficial effects of which are:
[0015] This invention utilizes an inverted U-shaped base that directly engages with both sides of a double-channel steel beam. This design prevents the threaded column from easily wobbling when the keel beam is placed on the top support. Compared to the connecting plate in existing technologies, the U-shaped plate of the inverted U-shaped base provides two additional sidewalls for positioning, making it easier to fix. Furthermore, because the keel beam is equipped with a limiting head, the top support can be directly positioned at both ends of the keel beam. The keel beam directly limits the distance between the two inverted U-shaped bases, eliminating the need for connecting rods, simplifying the installation process, and improving construction efficiency.

[0022] The specific embodiments of this utility model are described below to enable those skilled in the art to understand this utility model. However, it should be understood that this utility model is not limited to the scope of the specific embodiments. For those skilled in the art, as long as various changes are within the spirit and scope of this utility model as defined and determined by the appended claims, these changes are obvious. All utility model creations utilizing the concept of this utility model are within the scope of protection.
[0023] Considering the problem that existing technologies using connecting plates for support in double-channel steel beams reduce installation efficiency—for example, CN217106133U discloses a socket-type disc-lock steel pipe support frame double-channel steel beam system where the connecting plates are fixedly connected by connecting crossbars, increasing the structural complexity and reducing installation efficiency—this embodiment provides a basement disc-lock frame double-channel steel beam structure with added limiting sidewalls, which is shown in detail below.
[0024] refer to Figure 1 A basement disc-lock frame double-channel steel support beam structure with added limiting sidewalls includes two opposing uprights 1, with two transversely arranged channel steel beams 2 fixed between the two uprights 1. Connecting discs are welded to both uprights 1, and these connecting discs support the channel steel beams 2.
[0025] Both channel steel beams 2 are U-shaped steel beams. The two channel steel beams 2 are set horizontally with their openings facing away from each other. Each channel steel beam 2 has multiple equally spaced bolt holes, and the two channel steel beams 2 are bolted together through the multiple bolt holes.
[0026] refer to Figure 1 and Figure 2 Two inverted U-shaped supports 3 are provided on the two channel steel beams 2. Each inverted U-shaped support 3 includes a U-shaped plate 31 that opens and engages with both sides of the two channel steel beams 2. Bolts for connecting the two channel steel beams 2 are provided on both sides of each U-shaped plate 31. The bolts between the two channel steel beams 2 not only serve as a connection but also restrict the movement of the U-shaped plate 31.
[0027] Each U-shaped plate 31 has a vertical sleeve in the middle, and each sleeve has a threaded post 32 fixedly connected to it. The top of each threaded post 32 is welded to a top support 4. Two top supports keel beams are supported on the two top supports 4, and limit heads 5 are set at both ends of the keel beams. The length of the keel beams is less than the distance between the two uprights 1. This setting of the keel beam length avoids direct collision between the beam ends and the uprights 1, reserves space for deformation compensation, and improves the structural safety margin.
[0028] As a further embodiment, refer to Figure 3 Each limiting head 5 includes two limiting plates 51 arranged vertically opposite each other at the end of the keel beam. Each limiting plate 51 has a through groove in the middle for the positioning bolt 52 to pass through. The positioning bolt 52 and the limiting plate 51 can prevent the keel beam from swaying on the top support 4. The limiting plate 51 with the through groove in the middle uses less material than the limiting block of the entire solid structure.
[0029] In this implementation, refer to Figure 3 and Figure 4 Each limiting plate 51 is a plate structure that is a right trapezoid in frontal projection and an isosceles trapezoid in top projection. This structure of the limiting plate 51 can reduce the volume of the limiting plate 51 and the weight of the keel beam.
[0030] In summary, the beneficial effects of this plan are as follows:
[0031] The structure of the inverted U-shaped base bracket 3 directly engaging with both sides of the double channel steel beam 2 ensures that the threaded column 32 is not easily shaken when the keel beam is placed on the top support 4. The U-shaped plate 31 of the inverted U-shaped base bracket 3 provides two additional side wall surfaces that can limit the movement compared to the connecting plate in the prior art, making it easier to fix. At the same time, since the keel beam is equipped with a limiting head 5, the top support 4 can be directly located at both ends of the keel beam. The distance between the two inverted U-shaped base brackets 3 is directly limited by the keel beam, avoiding the need for connecting rods, simplifying the installation steps, and improving construction efficiency.
[0032] Although the specific embodiments of the utility model have been described in detail with reference to the accompanying drawings, this should not be construed as limiting the scope of protection of this patent. Various modifications and variations that can be made by those skilled in the art without inventive effort within the scope described in the claims still fall within the scope of protection of this patent.
