Description

Technical Field

[0001] This utility model relates to a load-bearing beam, and more particularly to a load-bearing beam for steel structure workshops used in the field of building beams. Background Technology

[0002] Load-bearing beams for steel structure workshops are an important component of steel structure buildings, mainly serving to support and transfer loads.

[0003] Chinese utility model patent CN213418061U discloses a steel structure beam that is easy to connect, belonging to the field of steel structure technology. The beam includes a first beam and a second beam, with the first beam located to the left of the second beam. Both ends of the first beam are bolted to a first mounting plate, and the end of the first mounting plate furthest from the first beam is fixedly connected to a first retaining seat. Similarly, both ends of the second beam are bolted to a second mounting plate, and the end of the second mounting plate furthest from the second beam is fixedly connected to a second retaining seat. A plug is fixedly connected to the left end of the second retaining seat, and a slot matching the plug is chiseled on the right end of the first retaining seat. This design enables a stable and efficient connection between the two beams. During beam connection construction, the pre-connection method effectively avoids significant disturbance between the two beams, facilitating bolt connection work and significantly improving the construction efficiency of bolted steel structure beam connections.

[0004] When splicing load-bearing beams in existing steel structure workshops, splicing or plugging methods are usually used to splice them on the same horizontal axis. However, in actual construction, there are corners in the beams, meaning that two adjacent beams are not on the same axis, which limits the applicability of the beams. Utility Model Content

[0005] In view of the above-mentioned prior art, the technical problem to be solved by this utility model is how to improve the applicability of the crossbeam.

[0006] To address the aforementioned problems, this utility model provides a load-bearing crossbeam for steel structure workshops, comprising an I-shaped component. The I-shaped component has insertion grooves on both sides, with a crossbeam component embedded within each groove. Constraint rods are mounted on the front and back of the I-shaped component via shafts. A notch is provided on the bottom wall of each insertion groove, with one end of the notch rotatably connected to a movable component via a shaft. The end of the movable component is bolted to the bottom end of the constraint rod. Several supporting units, located between constraint rods on one side, are fitted onto the surface of the I-shaped component. Each supporting unit includes a supporting frame, with an elastic component mounted on the top of the supporting frame. A sliding groove is provided on the outer surface of the supporting frame, and an insertion component is slidably connected inside the sliding groove. An edge block is fixedly connected to the surface of the insertion component.

[0007] In the aforementioned load-bearing beams for steel structure workshops, the combination of movable parts, I-beams, and constraint rods can adapt to different splicing requirements of the beam components.

[0008] As a further improvement of this application, the length of the notch is less than the cross-sectional length of the insertion groove, and the end of the notch away from the shaft is flush with the end of the insertion groove.

[0009] As a further improvement of this application, the sum of the depth values ​​of the two insertion slots is less than the thickness value of the I-shaped part, and the connection position of the constraint rod and the shaft is close to the opening end of the insertion slot.

[0010] As a further improvement of this application, the inner surfaces of the elastic element and the lifting frame are in contact with the surface of the I-shaped element, and the top of the lifting frame is located below the shaft.

[0011] As a further improvement of this application, the side block is provided with screw holes inside, the shaft is a self-resetting rotating shaft, and the constraint rod is placed horizontally in the initial state, and the constraint rod is located above the insertion slot in the initial state.

[0012] As a further improvement to this application, there is a vertical gap between the top of the connector and the top of the side block, and the height of the side block when it moves to the top position in the sliding groove is lower than the height of the top of the I-shaped part.

[0013] As a further improvement to this application, the inner wall of the notch is provided with a magnetic suction hole, and the surface of the movable part is provided with a plug-in magnetic rod that matches the magnetic suction hole.

[0014] In summary, by utilizing the coordination of the movable component, the I-beam, and the constraint rod, when two crossbeams need to be spliced ​​non-horizontally, the movable component can be rotated to provide support at the bottom of the subsequently tilted crossbeam. The constraint rod can then be swung so that its tail end overlaps with the end surface of the movable component, allowing for subsequent bolting. Furthermore, the lifting unit allows the spliced ​​crossbeam and I-beam to have multiple support and lifting structures, thus improving the problem of heavy support loads caused by relying solely on the I-beam at the splicing position in existing technologies.

[0025] The two embodiments of this application will be described in detail below with reference to the accompanying drawings.

[0026] First implementation method:

[0027] Figure 1-2 The diagram shows a load-bearing crossbeam for a steel structure factory building, including an I-shaped member 1. The two sides of the I-shaped member 1 are provided with insertion grooves 5. A crossbeam member 2 is embedded inside each insertion groove 5. Constraint rods 3 are installed on the front and back of the I-shaped member 1 through shafts. The bottom wall of each insertion groove 5 is provided with a notch. One end of the notch is rotatably connected to a movable member 4 through a shaft. The end of the movable member 4 is connected to the bottom end of the constraint rod 3 by bolts.

[0028] The length of the notch is less than the cross-sectional length of the insertion groove 5, and the end of the notch away from the shaft is flush with the end of the insertion groove 5.

[0029] The sum of the depths of the two insertion slots 5 is less than the thickness of the I-shaped part 1, and the connection position of the constraint rod 3 and the shaft is close to the opening end of the insertion slot 5.

[0030] The inner surfaces of the elastic element 8 and the lifting frame 6 are in contact with the surface of the I-shaped element 1, and the top of the lifting frame 6 is located below the shaft.

[0031] Figure 3 As shown, the shaft is a self-resetting rotating shaft, and in the initial state, the constraint rod 3 is placed horizontally, and in the initial state, the constraint rod 3 is located above the insertion slot 5.

[0032] The inner wall of the notch is provided with a magnetic suction hole 10, and the surface of the movable part 4 is provided with a plug-in magnetic rod that matches the magnetic suction hole 10.

[0033] Specifically, in this embodiment, the magnetic suction hole 10 and the insertion magnetic rod attract each other, so that when the movable member 4 is fitted into the notch, the movable member 4 can maintain stable contact with the notch.

[0034] When splicing two crossbeams 2, if the two crossbeams 2 need to be spliced ​​horizontally (at this time, the crossbeams 2 are kept in a suspended position, so that the crossbeams 2 are less labor-intensive during splicing), then the two crossbeams 2 only need to be directly inserted into the insertion slot 5, and then the constraint rod 3 is lowered (at this time, there is a gap between one end of the crossbeam 2 and the insertion slot 5, which can be filled by the abutment, where the abutment is an existing technology and can be a structure such as concrete fragments from construction waste), so that the tail end of the constraint rod 3 is bolted to the end of the movable part 4, and the crossbeams 2 can be stably spliced ​​and constrained.

[0035] If the two crossbeams 2 need to be joined non-horizontally, the movable part 4 is rotated around the shaft as needed, so that the movable part 4 can provide support at the bottom of the subsequently tilted crossbeam 2, and the constraint rod 3 is swung so that the tail end of the constraint rod 3 overlaps with the end surface of the movable part 4, and then the bolting operation can be performed (e.g. Figure 4 (As shown).

[0036] Second implementation method:

[0037] Figure 5-6 The surface of the I-shaped part 1 is fitted with several lifting units located in the middle of the constraint rods 3 on one side. The lifting unit includes a lifting frame 6, an elastic member 8 is installed at the top of the lifting frame 6, a sliding groove 9 is provided on the outer surface of the lifting frame 6, and a plug 71 is slidably connected inside the sliding groove 9. A side block 7 is fixedly connected to the surface of the plug 71.

[0038] The side block 7 has a screw hole inside. There is a vertical gap between the top of the plug 71 and the top of the side block 7. When the side block 7 moves to the top position inside the sliding groove 9, its height is lower than the top height of the I-shaped part 1.

[0039] Unlike the first embodiment, this embodiment mainly provides a lifting unit to provide additional support for the spliced ​​crossbeam 2. Compared with the prior art, which only relies on splicing parts for support at the splicing position, this embodiment uses a lifting unit to provide additional support, which can enhance the support stability of the crossbeam 2.

[0040] Specifically, after the crossbeam 2 is assembled, the constraint rod 3 and the movable part 4 are not bolted on first. The lifting frame 6 is moved and the elastic part 8 (the elastic part 8 can be made of rubber or other elastic material) is pulled open, so that the bottom end of the elastic part 8 can be opened, allowing the entire lifting unit to move smoothly past the position of the axle (e.g., Figure 7 (As shown), then release the elastic element 8 until the lifting unit moves to the center position of the crossbeam 2 (or another position, in short, so that the lifting unit maintains a certain distance from the I-shaped element 1, such as...). Figure 8 As shown), move the side block 7 to the top position of the sliding groove 9 and continue to move it upward until the inner wall of the lifting frame 6 contacts the bottom of the crossbeam 2 (because the lifting frame 6 initially contacts the bottom surface of the I-shaped part 1 during the initial transfer, there is a gap between the surface of the lifting frame 6 and the bottom surface of the crossbeam 2 when it moves to the crossbeam 2, so it needs to continue to move upward in order to support the crossbeam 2 in the future). At this time, the side block 7 is flush with the top of the I-shaped part 1. Then, the hoisting operation can be completed by using bolts, and the top of the I-shaped part 1 will not cause any interference at this time.

[0041] In summary, this application utilizes the cooperation of movable part 4, I-shaped part 1, and constraint rod 3 to enable the movable part 4 to rotate and provide support at the bottom of the subsequently tilted beam 2 when the two crossbeams 2 need to be spliced ​​horizontally. This allows the movable part 4 to swing so that the tail end of the constraint rod 3 overlaps with the end surface of the movable part 4, after which bolting can be performed. Furthermore, the lifting unit allows the spliced ​​beam 2 and I-shaped part 1 to have multiple support and lifting structures, thereby improving the problem of heavy support load caused by the lifting of the I-shaped part 1 at the splicing position in the prior art.

[0042] In light of current practical needs, the above-described embodiments adopted in this application are not limited to these. Any changes made within the scope of knowledge possessed by those skilled in the art without departing from the concept of this application still fall within the protection scope of this utility model.
