Description

Technical Field

[0001] The utility model relates to the technical field of building reinforcement equipment, in particular to a novel reinforcement structure of a crossbeam combined with steel bars. Background Art

[0002] Crossbeams are horizontal beams that are perpendicular to the longitudinal beams and are arranged along the short axis of the building. They are extremely important load-bearing structures in the building structure and are mainly used to support the top of the building. After the construction is completed, if the building is expanded or renovated, or when the load-bearing capacity is calculated after the building's load-bearing structure is poured, if the load-bearing performance of the crossbeams cannot meet the requirements of the specifications, the crossbeams need to be further reinforced.

[0003] In existing reinforcement structures, various steel structures are often added to the outside of the beams. This not only makes the construction process complex and the transformation difficult, but also makes it difficult to accurately calculate the change in bearing capacity after reinforcement. At the same time, it is difficult to share the bearing capacity without deforming the original beams, and cannot meet the construction requirements of large buildings. To this end, we propose a new reinforcement structure that combines beams with steel bars to solve the above problems. Utility Model Content

[0004] The purpose of the utility model is to solve the problems existing in the prior art and to propose a new type of reinforcement structure of a crossbeam combined with steel bars.

[0005] In order to achieve the above purpose, the present invention adopts the following technical solutions:

[0006] A novel crossbeam combined with steel bar reinforcement structure comprises a vertical beam body and a crossbeam body, wherein the vertical beam body and the crossbeam body are fixedly connected to additional steel bars, and the additional steel bars are fixedly connected to a support frame assembly;

[0007] The support frame assembly includes a reinforced base plate fixedly connected to the lower surface of the beam body, a connecting rod fixedly connected to the lower surface of the reinforced base plate, and the connecting rod fixedly connected to the additional steel bars located on the vertical rod body, a plurality of diagonal support rods fixedly connected to the upper surface of the reinforced base plate, the upper ends of the diagonal support rods fixedly connected to the additional steel bars located on the beam body, and a traction platform is also provided on the vertical beam body.

[0008] Preferably, the traction platform includes a connecting plate, a plurality of fixing holes are opened on the connecting plate, and extension plates are provided on both sides of the connecting plate, a connecting rod is fixedly connected to the extension plate, and the connecting rod is fixedly connected to the reinforcing base plate.

[0009] Preferably, vertical plates are fixedly connected to both sides of the reinforcing bottom plate, and the reinforcing bottom plate and the vertical plates are fixedly connected to the lower surface of the beam body by adhesive steel glue.

[0010] Preferably, the connecting rod includes a frame body, threaded holes are provided at both ends of the frame body, and threaded rods are threadedly connected in the threaded holes. The two threaded rods are fixedly connected to the extension plate and the reinforcing base plate respectively, and a reinforcing block is provided at the connection point between the threaded rod and the reinforcing base plate.

[0011] Preferably, sealant is provided on the side walls of the additional steel bars close to the vertical beam body and the horizontal beam body.

[0012] Preferably, a cross frame is fixedly connected to the lower surface of the reinforced bottom plate, and both ends of the cross frame are fixedly connected to the reinforcement block.

[0013] Compared with the prior art, the beneficial effects of the present invention are:

[0014] 1. The utility model provides a support frame assembly and adopts a reinforced bottom plate to support the poured concrete layer. At the same time, diagonal braces are used in conjunction with additional steel bars to support the steel skeleton in the beam body. By providing connecting rods and additional steel bars, the bearing force is transmitted to the steel skeleton in the vertical beam body, optimizing the load-bearing structure and reasonably distributing the force on the bearing points. This can effectively reinforce the poured beam without causing damage to the original structure.

[0015] 2. The utility model sets up a traction platform, builds a support point on the top of the beam, and cooperates with the connecting rod to support the reinforced bottom plate, thereby further dispersing the force in the middle of the beam, reducing the risk of beam breakage, and improving the stability of the building structure. By setting sealant, the steel skeleton in the beam body and the vertical beam body is prevented from rusting at the place where the steel bars are installed. BRIEF DESCRIPTION OF THE DRAWINGS

[0021] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0022] Reference Figure 1-3 A novel crossbeam combined with steel bar reinforcement structure comprises a vertical beam body 1 and a horizontal beam body 2, wherein the vertical beam body 1 and the horizontal beam body 2 are fixedly connected with additional steel bars 3, and the additional steel bars 3 are fixedly connected with a support frame assembly;

[0023] The construction method of installing the steel bars 3 is to drill holes after the vertical beam body 1 and the horizontal beam body 2 are cast, and fix the installed steel bars 3 to the steel skeleton inside the vertical beam body 1 and the horizontal beam body 2 to ensure that the external load-bearing force is transmitted to the steel skeleton inside the vertical beam body 1 and the horizontal beam body 2, ensuring that the load-bearing distribution is consistent with the original design or optimizing the original design load-bearing force;

[0024] The support frame assembly includes a reinforcing base plate 4 fixedly connected to the lower surface of the crossbeam body 2, a connecting rod 5 fixedly connected to the lower surface of the reinforcing base plate 4, and the connecting rod 5 is fixedly connected to the additional steel bars 3 located on the vertical rod body, and a plurality of diagonal braces 6 are fixedly connected to the upper surface of the reinforcing base plate 4, and the upper ends of the diagonal braces 6 are fixedly connected to the additional steel bars 3 located on the crossbeam body 2. A traction platform is also provided on the vertical beam body 1;

[0025] In this design, the reinforced base plate 4 is used to support the concrete structure of the beam body 2, and the diagonal braces 6 are used to transmit the pressure to the vertical beams to ensure that the reinforced base plate 4 has a certain supporting force. At the same time, the diagonal braces 6 are used to support the steel skeleton in the beam body 2 to achieve comprehensive reinforcement of the beam body 2, ensure load distribution, stabilize the shape of the beam body 2, and avoid damage to the beam body 2 due to uneven force.

[0026] It should be noted that this reinforcement scheme of combining crossbeams with steel bars is a structure for strengthening the crossbeam load-bearing structure. Whether or not this reinforcement scheme is adopted has no effect on the load-bearing capacity of the vertical beams. If the vertical beams also need to be strengthened, other vertical beam reinforcement structures should be used for construction.

[0027] Furthermore, the traction platform includes a connecting plate 7, a plurality of fixing holes are opened on the connecting plate 7, and extension plates 8 are provided on both sides of the connecting plate 7, and connecting rods 9 are fixedly connected to the extension plates 8, and the connecting rods 9 are fixedly connected to the reinforcing bottom plate 4;

[0028] In this design, the connecting plate 7 is placed on the crossbeam body 2, and the connecting plate 7 is located directly above the vertical beam, ensuring that the force on the connecting plate 7 is mainly supported by the vertical beam body 1, reducing the load in the middle of the crossbeam body 2, and the extension plate 8 is fixed on both sides of the vertical beam body 1, and then the connecting rod 9 is used to apply lateral tension to the reinforcing steel plate to disperse the load-bearing capacity of the reinforced bottom plate 4.

[0029] Furthermore, vertical plates 10 are fixedly connected to both sides of the reinforcing bottom plate 4, and the reinforcing bottom plate 4 and the vertical plates 10 are fixedly connected to the lower surface of the beam body 2 by adhesive steel glue;

[0030] In this design, the vertical plate 10 is used to stabilize the structure of the beam body 2 and to cover and support the beam body 2 .

[0031] Furthermore, the connecting rod 9 includes a frame 91, with threaded holes provided at both ends of the frame 91, and threaded rods 92 threadedly connected to the threaded holes. The two threaded rods 92 are fixedly connected to the extension plate 8 and the reinforcing base plate 4 respectively, and a reinforcing block 93 is provided at the connection point between the threaded rods 92 and the reinforcing base plate 4;

[0032] This structure is similar to a turnbuckle, and the frame 91 can be rotated to adjust the total length of the connecting rod 9, which is convenient for the construction of the reinforcement project.

[0033] Furthermore, the side walls of the additional reinforcement 3 close to the vertical beam body 1 and the horizontal beam body 2 are provided with a sealant.

[0034] In this design, since the reinforcement 3 is installed by excavating concrete and connected to the reinforcement skeleton in the crossbeam body 2 and the vertical beam body 1, the excavation points need to be sealed to prevent the reinforcement skeleton from being exposed and rusted.

[0035] Furthermore, a cross frame 11 is fixedly connected to the lower surface of the reinforcing bottom plate 4 , and both ends of the cross frame 11 are fixedly connected to the reinforcing block 93 .

[0036] In this design, a cross frame 11 is provided to support the reinforcing base plate 4 and prevent the reinforcing base plate 4 from deformation.

[0037] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
