Technical Field

[0001] The utility model relates to the field of crossbeams, in particular to a crossbeam with a reinforcement structure. Background Art

[0002] Most of the existing crossbeam door frame structures adopt a simply supported beam structure, that is, it is directly placed on the column and fixed by a pressure plate to prevent displacement.

If this stress is to be dispersed, it is necessary to increase the number of rib plates or the thickness of the corner plates. This will greatly increase the overall weight of the crossbeam, increase the difficulty of processing and welding processes, and at the same time, the concentrated stress cannot be completely evenly dispersed, that is, there are still concentration points.

[0029] The utility model provides a crossbeam with a reinforced structure, the purpose of which is to install a connecting rib plate at one end of the crossbeam body so that the crossbeam body can be connected to the longitudinal beam or the longitudinal structure while also strengthening the vertical load-bearing strength of the crossbeam body. The added corner plate strengthens the strength of the horizontal angle of the connecting rib plate to the crossbeam body, so that the force is evenly applied and the bending moment strength of the crossbeam body is strengthened.

[0030] First, as Figure 1 As shown, in the first embodiment, a crossbeam with a reinforcement structure comprises a crossbeam body 1, and a connecting rib plate 3 is connected to either end of the crossbeam body 1. The connecting rib plate 3 plays a role in stabilizing the crossbeam and is also used to connect with other longitudinal beams or other forms of longitudinal load-bearing structures to play a connecting role;

[0031] The corner plate 4 is installed on the connecting rib plate 3 and partially inserted into the beam body 1. A slot matching the beam body 1 is provided on the corner plate 4. When the connecting rib plate 3 is connected to the longitudinal load-bearing structure, the corner plate 4 is used to reinforce and maintain the horizontal relative position of the two load-bearing structures (transverse and longitudinal), that is, to maintain a fixed angle.

[0032] The above-mentioned beam with a reinforcement structure, wherein a pressing plate 2 is installed at one end of the beam body 1 away from the connecting rib plate 3, and the pressing plate 2 is used to fix the beam to a column or a connecting plane to play a role in stabilizing the connection.

[0033] In the above-mentioned beam with a reinforcement structure, a reinforcement tube 5 is installed on the beam body 1, with one end connected to the connecting rib plate 3 and the other end extending to the end of the beam body 1 away from the connecting rib plate 3, which plays a reinforcement role.

[0034] Second, as Figure 1-2 As shown, in the second embodiment, a crossbeam with a reinforcement structure comprises a crossbeam body 1, and a connecting rib plate 3 is connected to either end of the crossbeam body 1. The connecting rib plate 3 plays a role in stabilizing the crossbeam and is also used to connect with other longitudinal beams or other forms of longitudinal load-bearing structures to play a connecting role;

[0035] The corner plate 4 is installed on the connecting rib plate 3 and partially inserted into the beam body 1. A slot matching the beam body 1 is provided on the corner plate 4. When the connecting rib plate 3 is connected to the longitudinal load-bearing structure, the corner plate 4 is used to reinforce and maintain the horizontal relative position of the two load-bearing structures (transverse and longitudinal), that is, to maintain a fixed angle.

[0036] In the above-mentioned beam with a reinforced structure, the beam body 1 is an H-shaped steel.

[0037] In the above-mentioned cross beam with a reinforced structure, the corner plate 4 is inserted into the middle part of the H-shaped steel.

[0038] The above-mentioned beam with a reinforced structure, wherein a pressure plate 2 is installed on the inner wall of either side of the H-shaped steel away from one end of the connecting rib plate 3, and the pressure plate 2 is used to fix the H-shaped steel to the column or the connecting plane to play a role in stabilizing the connection.

[0039] The above-mentioned beam with a reinforcement structure, wherein a reinforcement tube 5 is symmetrically installed on the inner wall of the side where the H-shaped steel is not provided with a pressure plate 2, which plays a balancing role. One end of the reinforcement tube 5 is connected to the connecting rib plate 3, and the other end extends to the end of the beam body 1 away from the connecting rib plate 3, and the reinforcement tube 5 plays a reinforcing role.

[0040] In the above-mentioned crossbeam with a reinforcement structure, the reinforcement pipe 5 is a square pipe, which is easy to install.

[0041] Due to the characteristics of H-beam, the cross-sectional shape is more able to withstand the force along the axial direction, that is, the pressure through the center of mass in the X, Y, and Z directions. However, for the eccentric force direction, that is, the force that produces torque, the cross-sectional shape of the H-beam cannot cope well. Compared with the axial force through the center of mass, a torque of an order of magnitude smaller can cause the H-beam to produce a torsional deformation, thereby causing the rectification mechanism to fail under force.

[0042] According to the technical solution provided by the utility model, one side of the H-shaped steel is fixed by the pressing plate 2, the connecting rib plate 3 is welded to the inner side surface and the upper and lower top surfaces of one end of the H-shaped steel, and the corner plate 4 is welded to the end surface of the connecting rib plate 3 close to the side of the H-shaped steel and inserted into the H-shaped steel. The pressing plate 2 presses the H-shaped steel and the ground, and prevents the H-shaped steel from horizontal displacement and vertical warping through friction and pressure. The connecting rib plate 3 not only connects the longitudinal structure, but also strengthens the vertical load-bearing strength of the H-shaped steel. The corner plate 4 strengthens and fixes the connecting rib plate 3 is for the strength of the horizontal angle of the H-shaped steel. The reinforcing pipe 5 is welded from the end face of the H-shaped steel to the side of the connecting rib plate 3. One side is welded to the inner side of the H-shaped steel and the other side is welded to the inner top of the H-shaped steel. This welding method changes the cross-sectional shape of the H-shaped steel, that is, changes the cross-sectional inertia moment of the H-shaped steel. While strengthening the axial force strength through the centroid and dispersing the concentrated stress, it also greatly strengthens the bending moment strength of the H-shaped steel. When the loads on both sides of the H-shaped steel are different, the deformation can be kept small or even not generated.

[0043] In the experiment, the deformation of the beam without the reinforcement tube 5 is 2.2 times greater than that with the reinforcement tube 5. Figure 3-4 As shown in FIG. 1 , the displacement effects of the H-shaped steel without the reinforcement tube 5 and the H-shaped steel with the reinforcement tube 5 under the same stress conditions are respectively produced. Figure 3 The deformation of the maximum deformation point (red part) is 3.81mm. Figure 4 The deformation at the maximum deformation point (red part) is 1.8mm.

[0044] In summary, the utility model is a beam with a reinforced structure, which installs a connecting rib plate at one end of the beam body so that the beam body can be connected to the longitudinal beam or the longitudinal structure while also strengthening the vertical load-bearing strength of the beam body. The added corner plate strengthens the strength of the horizontal angle of the connecting rib plate to the beam body, making the force uniform and strengthening the bending moment strength of the beam body.

[0045] The above describes the specific embodiments of the utility model. It should be understood that the utility model is not limited to the above specific embodiments, and the devices and structures not described in detail should be understood to be implemented in a common manner in the art; those skilled in the art can make various modifications or modifications within the scope of the claims to make some simple deductions, deformations or substitutions, which does not affect the substantive content of the utility model.
