Description

Technical Field

[0001] This utility model relates to the field of civil engineering construction technology, specifically to a reinforcement structure for beam support plates. Background Technology

[0002] A beam-slab support system refers to a complete support structure system formed by interconnecting beams and slabs to withstand various loads and transmit forces. The beam-slab support system is usually composed of main components such as horizontal beams, longitudinal beams, and floor slabs. Through reasonable connection and structural design, the stability and load-bearing capacity of the overall structure are achieved.

[0003] Currently, in the design of beam-supported slabs in multi-story and high-rise buildings, the traditional reinforcement arrangement generally adopts a staggered arrangement of transverse and longitudinal bidirectional reinforcing bars. Although this arrangement can meet the structural strength requirements to a certain extent, it still has some shortcomings in actual engineering. With the continuous development of building structural design, the performance requirements for beam-supported slabs are becoming increasingly higher. They not only need to ensure sufficient load-bearing capacity and stiffness, but also need to have good seismic performance and economy. The existing reinforcement methods can no longer fully meet these requirements.

[0004] Currently, the commonly used reinforcement methods for beam-support slabs mainly include: 1) Staggered arrangement of two-way reinforcing bars: This method uses interlaced transverse and longitudinal reinforcing bars to form a grid structure, which can effectively distribute the load and improve overall stability. However, the small spacing between the reinforcing bars increases construction difficulty and requires a large amount of reinforcing bars, resulting in higher costs. 2) Unidirectional reinforcing bars with additional reinforcement: This method mainly relies on unidirectional reinforcing bars to bear the main load, supplemented by a small amount of additional reinforcement to enhance local strength. Although it can reduce the amount of reinforcing bars, the overall stiffness is poor and the shear resistance is insufficient. 3) Prestressed reinforcement arrangement: This method uses prestressing technology to pre-stretch the reinforcing bars, thereby improving the overall strength and stiffness of the beam-support slab. Although this method is effective, it is complex to construct and costly, making it unsuitable for ordinary civil buildings. Therefore, there is an urgent need for a new reinforcement structure for beam-support slabs that can reduce construction difficulty and cost while ensuring structural strength and stiffness. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a reinforced structure for beam support plates, which has advantages such as high structural strength and stiffness, low construction difficulty and low cost, and solves the problems of increased construction difficulty, large amount of steel reinforcement, and high cost.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a beam support plate reinforcement structure, comprising two beams, with two main reinforcement bars fixed at the top between opposite sides of the two beams in a vertically symmetrical manner, both ends of the main reinforcement bars penetrating the beams and extending into the inner cavity of the beams, and multiple distribution bars provided at the left and right ends of the opposite sides of the main reinforcement bars on the upper and lower sides.

[0007] A fine mesh of steel bars is fixed between the main reinforcement and the distribution reinforcement on the opposite side. Additional reinforcements are fixed at both ends between the main reinforcement and the beam body on the opposite side. The outer surfaces of the main reinforcement, distribution reinforcement, fine mesh reinforcement and additional reinforcement are all coated with anti-corrosion paint.

[0008] By adopting this technical solution, the structural strength and stiffness of the beam support plate are improved, enabling it to maintain stable performance under heavy loads. This simplifies the construction process, reduces construction difficulty and cost, and is suitable for large-scale application. At the same time, it enhances the seismic performance of the beam support plate, enabling it to maintain good stability and safety under extreme conditions such as earthquakes.

[0009] Furthermore, the diameter of the main reinforcement bar is 16mm, and the spacing between two main reinforcement bars is 200mm.

[0010] By adopting this technical solution, we can ensure robustness and reliability to adapt to different load requirements.

[0011] Furthermore, the diameter of the distribution rib is 8mm, and the length of the distribution rib in the vertical direction is 150mm.

[0012] By adopting this technical solution, the integrity of the structure is ensured.

[0013] Furthermore, the main reinforcement has a U-shaped cross-section, and the distribution reinforcement has an inverted Z-shaped cross-section.

[0014] Furthermore, the additional reinforcement has an L-shaped cross-section and a diameter of 10 mm.

[0015] By adopting this technical solution, the main reinforcement and distribution reinforcement together form a strengthening zone, enhancing the stiffness and stability of the corner.

[0016] Furthermore, both the main reinforcement and the additional reinforcement are fixed to the inner cavity of the beam by anchors, which are M12 bolts.

[0017] By adopting this technical solution, the goal of fixing the main reinforcement and additional reinforcement inside the beam is achieved, ensuring a good bond between the steel reinforcement and the concrete, and improving the overall load-bearing capacity.

[0018] Furthermore, the fine mesh reinforcement includes horizontal and vertical bars that are interleaved.

[0019] This technical solution is used to enhance the stiffness and crack resistance of the intermediate region.

[0020] Furthermore, the anti-corrosion coating is an epoxy resin coating.

[0021] By adopting this technical solution, the service life is extended and the durability is improved. The anti-corrosion coating can provide good protection for the steel bars, prevent the steel bars from contacting moisture and oxygen, and reduce the risk of steel bar corrosion.

[0022] Compared with the prior art, the technical solution of this application has the following beneficial effects:

[0023] This reinforced structure of the inter-beam support plate improves the structural strength and stiffness of the inter-beam support plate, enabling it to maintain stable performance under heavy loads. It simplifies the construction process, reduces construction difficulty and cost, and is suitable for large-scale application. At the same time, it enhances the seismic performance of the inter-beam support plate, enabling it to maintain good stability and safety under extreme conditions such as earthquakes. Furthermore, the anti-corrosion coating provides good protection and reduces the risk of steel corrosion. Attached Figure Description

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0029] Please see Figures 1 to 3This embodiment of a beam-support plate reinforcement structure includes two beams 1. Two main reinforcing bars 2 are fixed at the top between opposite sides of the two beams 1, and both ends of the main reinforcing bars 2 penetrate the beams 1 and extend into the inner cavity of the beams 1. Anchors are pre-embedded inside the beams 1. Then, the main reinforcing bars 2 are laid according to the design drawings to ensure that the spacing between the main reinforcing bars 2 is uniform and parallel to the horizontal direction of the beam-support plate. Then, they are fixed with tie wire. The tie wire is an existing structure and will not be described in detail here. The main reinforcing bars 2 are mainly used to bear longitudinal loads. Multiple distribution bars 3 are provided at the left and right ends of opposite sides of the main reinforcing bars 2. The distribution bars 3 are used to distribute transverse loads. When laying the distribution bars 3, multiple distribution bars 3 are perpendicular to the fine mesh steel bars 4 and are spot welded at the intersection to ensure the integrity of the structure.

[0030] Fine mesh steel bars 4 are fixed between the main reinforcement 2 and the distribution reinforcement 3 on the opposite side to enhance the rigidity and crack resistance of the middle area. Additional reinforcement bars 5 are fixed at both the upper and lower ends between the main reinforcement 2 and the beam 1 on the opposite side. Additional reinforcement bars 5 are installed at the four corners between the main reinforcement 2 and the beam 1 on the opposite side to form an L-shaped structure, so that the additional reinforcement bars 5, the main reinforcement 2 and the distribution reinforcement 3 together form a reinforced area. Then, they are fixed with tie wire to enhance the rigidity and stability of the corners. The outer surfaces of the main reinforcement 2, distribution reinforcement 3, fine mesh steel bars 4 and additional reinforcement bars 5 are all coated with anti-corrosion coating 6. Anti-corrosion coating 6 can extend the service life of the steel bars and improve their durability. Anti-corrosion coating 6 can provide good protection for the steel bars, prevent the steel bars from contacting moisture and oxygen, and reduce the risk of steel bar corrosion.

[0031] In addition, high-strength steel wire ropes are pre-embedded inside beam 1, so that the high-strength steel wire ropes, main reinforcement 2 and additional reinforcement 5 together form a three-dimensional reinforcement structure, which further improves the overall load-bearing capacity and seismic performance of the support plates between beams 1.

[0032] In this embodiment, the diameter of the main reinforcement 2 is 16mm, the spacing between two main reinforcements 2 is 200mm, the diameter of the distribution reinforcement 3 is 8mm, the length of the distribution reinforcement 3 in the vertical direction is 150mm, the cross-sectional shape of the main reinforcement 2 is U-shaped, and the cross-sectional shape of the distribution reinforcement 3 is inverted Z-shaped.

[0033] The additional reinforcement 5 has an L-shaped cross-section and a diameter of 10mm. Both the main reinforcement 2 and the additional reinforcement 5 are fixed to the inner cavity of the beam 1 by anchors. The anchors are M12 bolts, which have high strength, stable connection, and are easy to construct. The fine mesh reinforcement 4 includes interlaced horizontal and vertical reinforcements. The anti-corrosion coating 6 is an epoxy resin coating. Epoxy resin coating is a commonly used anti-corrosion coating for steel bars. It has excellent corrosion resistance and adhesion. It can provide good protection, prevent steel bars from contacting moisture and oxygen, reduce the risk of steel bar corrosion, and improve the stability and safety of concrete structures.

[0034] It should be noted that the main reinforcement 2, distribution reinforcement 3 and additional reinforcement 5 are all HRB400 steel bars. HPB400 steel bars are a type of hot-rolled plain round steel bar with a yield strength of 400 MPa. They are mainly used for reinforcement in building construction. Because HPB400 steel bars have high strength, they are often used to bear large loads.

[0035] Understandably, throughout the process, anchors are used to fix the main reinforcement 2 and the additional reinforcement 5 inside the beam 1, ensuring a good bond between the steel bars and the concrete, improving the overall load-bearing capacity. Through the cooperation between the various structures, the structural strength and stiffness of the support plate between the beams 1 are improved, enabling it to maintain stable performance under large loads. This not only simplifies the construction process but also reduces construction difficulty and cost, making it suitable for large-scale promotion and application. In addition, it also enhances the seismic performance of the support plate between the beams 1, enabling it to maintain good stability and safety under extreme conditions such as earthquakes.

[0036] The working principle of the above embodiments is as follows:

[0037] During construction, anchors are first pre-embedded inside beam 1. Then, main reinforcement bars 2 are laid according to the design drawings, ensuring that the spacing between main reinforcement bars 2 is uniform and parallel to the long side of the support plate between beams 1. They are then fixed with ties. Next, fine mesh reinforcement bars 4 are laid to enhance the rigidity and crack resistance of the central area. Then, distribution reinforcement bars 3 are laid, ensuring that multiple distribution bars 3 intersect perpendicularly with the fine mesh reinforcement bars 4, and are spot-welded at the intersections to ensure the integrity of the structure. Finally, additional reinforcement bars 5 are installed at the four corners between the main reinforcement bars 2 and the opposite side of beam 1, forming an L-shaped structure. This, together with the main reinforcement bars 2 and distribution reinforcement bars 3, constitutes a reinforced area, which is fixed with ties. The installation of all reinforcement bars is checked to ensure there is no loosening or misalignment; adjustments are made if necessary. Finally, a coating can be applied to the surface of all reinforcement bars. Anti-corrosion coating 6 is used to extend service life and improve durability. Next, concrete is poured, ensuring it is dense and free of air bubbles, covering all reinforcing bars to achieve the designed thickness. Throughout the process, anchors are used to fix the main reinforcing bars 2 and additional reinforcing bars 5 inside the beam 1, ensuring a good bond between the reinforcing bars and concrete and improving the overall load-bearing capacity. The main reinforcing bars 2 are mainly used to bear longitudinal loads, the distribution bars 3 are used to disperse lateral loads, and the additional reinforcing bars 5 enhance corner stiffness, jointly ensuring the structural safety of the supporting slab between beams 1. Anti-corrosion coating 6 uses epoxy resin coating, a commonly used steel reinforcement anti-corrosion coating 6, which has excellent corrosion resistance and adhesion. It provides good protection, preventing the reinforcing bars from contacting moisture and oxygen, reducing the risk of steel corrosion, and improving the stability and safety of the concrete structure.
