Description

Technical Field

[0001] This utility model relates to the technical field of beams and columns, specifically to a prefabricated light steel keel structure multifunctional beam and column. Background Technology

[0002] Crossbeams are used in large-scale event construction, particularly in convention and stage construction. These crossbeams are often also called "trusses." They are used to construct supports and to secure lighting equipment, loudspeakers, and other stage-related fixtures. Here, the crossbeams are arranged both vertically and horizontally to establish a proper structure. The crossbeams comprise parallel crossbeam members connected to each other by cross braces extending at an angle relative to or perpendicular to the longitudinal extension of the crossbeam members.

[0003] Crossbeams typically have a fixed length. To construct larger structures, crossbeams are interconnected. It is known that two crossbeams are connected by mating flanges and removable pins extending through the flanges. In this technique, adjacent crossbeams must be oriented such that the pin can extend through the end flanges of one crossbeam and the end flanges of the adjacent crossbeam. Therefore, it is time-consuming and labor-intensive to first orient the crossbeams and hold them in this orientation while simultaneously inserting the pins into the flanges. Furthermore, the position of the flanges must be considered when setting up the crossbeams. Utility Model Content

[0004] This utility model provides a prefabricated light steel keel structure for multifunctional beams and columns. This structure can be used as a beam structure or a column structure. The mortise and tenon structure with interference fit or slight threaded stop design allows one person to easily connect two beams with one hand, greatly simplifying the manpower requirements on the construction site.

[0005] The present invention solves the above-mentioned technical problems through the following technical solution:

[0006] A prefabricated light steel keel structure multifunctional beam and column includes: the beam structure has a basic structure in the shape of a cuboid, and one side of the cuboid is provided with a tenon and mortise structure for insertion.

[0007] In one specific embodiment, each side of the cube is provided with a tenon and mortise structure for insertion.

[0008] In a specific embodiment, the mortise and tenon structure includes a first insertion segment and a second insertion segment. The spacing between the first insertion segments is smaller than that between the second insertion segments, and the first insertion segment is located outside the second insertion segment. The first insertion segment and the second insertion segment are stepped.

[0009] In a specific embodiment, the first insertion segment comprises two parallel sides, and its bottom side is the outer side of the second insertion segment; the second insertion segment comprises two parallel sides and a bottom side, and the two sides of the second insertion segment are arranged parallel to the two sides of the first insertion segment.

[0010] In a specific embodiment, the groove structure formed by the first insertion segment and the second insertion segment extends along the side of the cube and traverses the entire side structure of the cube.

[0011] In one specific embodiment, the cube is composed of four sides, which are arranged perpendicularly to each other, and each side has at least one tenon structure in the middle.

[0012] The beneficial effects of this utility model are as follows:

[0013] 1. This utility model features a direction-free, quick-connect assembly. Traditional flange + pin connections require aligning the flange face and maintaining stable orientation, which is time-consuming and labor-intensive. The new solution utilizes tenon and mortise structures on all four sides of the cuboid and a stepped matching insertion section, allowing for quick insertion without repeated orientation adjustments. This eliminates the three major steps of "finding the correct flange—maintaining orientation—inserting the pin," significantly improving assembly efficiency. The tenon and mortise structure, combined with an interference fit or a slight threaded stop design, allows one person to easily connect two crossbeams with one hand, greatly simplifying the manpower requirements on the construction site.

[0014] 2. The stepped insertion sections (first and second insertion sections) form a self-guiding mechanism during insertion, automatically aligning the two crossbeams in three-dimensional space (X / Y / Z axes) to ensure the flatness and perpendicularity of the joint. The mortise and tenon groove structure runs across the side of the crossbeam, forming a continuous load-bearing surface, replacing the point-pin structure, effectively dispersing shear loads, and improving overall stiffness and torsional resistance.

[0015] 3. Integrated components: All beams have identical cuboid structures on their sides, allowing any beam unit to be plugged into adjacent units in any direction without the need for fixed-length or directional flange fittings, thus achieving component universality. Standardized cuboid units facilitate modular and automated production, reducing the design and manufacturing costs of irregularly shaped parts.

[0016] 4. Beams and columns can be flexibly combined, and can be used to fix door and window frames, or as beams when the wall height is greater than 7.5m; it can also realize a variety of wall forms, including right-angle walls, cross walls, T-shaped walls, straight walls, etc., to meet different architectural space and structural needs.

[0017] 5. The grooves on the sides of the cube are used to quickly and firmly connect the panels, improving the overall assembly stability, and also serve as reinforcing ribs distributed on the sides of beams and columns, significantly improving the bending and torsional strength of the beams.

[0018] 6. A sealed partition structure is installed at the connection between the wall and the column. The tight fit between the partition wall and the column can effectively block the propagation of sound waves and enhance the sound insulation effect of the wall. Attached Figure Description

[0023] The following description, in conjunction with the accompanying drawings, illustrates a specific embodiment of the present invention, "a prefabricated light steel keel structure multifunctional beam and column," but the invention is not limited to this embodiment.

[0024] Example 1

[0025] As attached Figure 1 As shown, the modular beam 1 includes a basic cuboid frame 2, which is formed by four mutually perpendicular cuboid side panels 21, and the frame cross-section is square.

[0026] A mortise and tenon joint structure 3 is symmetrically provided at the center of each side surface 21 of the cube, and the mortise and tenon joint structure 3 runs horizontally across the entire surface of the cube along the side surface.

[0027] The mortise and tenon joint structure 3 includes a first insertion section 31 located on the inner side of the side and a second insertion section 32 located on the outer side of the side.

[0028] The two sides 311 of the first insertion segment 31 are parallel to each other, and its bottom side 312 is coplanar with the outer side 322 of the second insertion segment 32.

[0029] The two sides 321 of the second insertion segment 32 are parallel to the sides of the first insertion segment 31, and its bottom side 323 is flush with the side surface 21 of the cube.

[0030] The first insertion section 31 and the second insertion section 32 are arranged in a stepped staggered manner on the side 21 to form a stepped groove, which is used to cooperate with the corresponding insertion teeth on the adjacent crossbeam unit 1.

[0031] At the connection surface of adjacent beam units, a quick plug-in connection without external pins is achieved by sliding the tenon and mortise joint structure 3 of one unit axially into the corresponding groove of another unit. During the insertion process, the second insertion section 32 first cooperates with the groove at the opposite end for guidance, and then the first insertion section 31 penetrates and locks in place, completing the self-locking position.

[0032] Assembly and disassembly methods

[0033] Bring the beam units close to each other so that the tenon and mortise joint structure 3 on one side aligns with the corresponding groove of the other unit;

[0034] Advance in a straight line, using the stepped guide of the second insertion segment 32 to achieve rapid insertion;

[0035] When the first insertion segment 31 is fully inserted, a clicking sound confirms that it is locked.

[0036] When disassembly is required, simply pull the two units outwards by hand in the opposite direction to separate them; no tools are needed.
