Description

Technical Field

[0001] This application relates to the field of structural reinforcement technology, and in particular to a reinforcement structure for improving the shear resistance of the ends of large-span frame beams. Background Technology

[0002] Large-span frames typically refer to frame structure systems with large spans, generally 18 meters or more (the span may vary slightly depending on the industry and application). They mainly rely on beams, columns, and other components connected by rigid or hinged joints to jointly bear vertical loads (such as the building's own weight, the weight of people and equipment, etc.) and horizontal loads (such as wind loads, seismic forces, etc.), forming a stable spatial structure that provides the building with open interior space.

[0003] Under long-span conditions, existing traditional frame beams suffer from shear force concentration at the beam ends, leading to problems such as concrete cracking and shear failure. Furthermore, conventional stirrup reinforcement methods are insufficient to meet shear resistance requirements, and construction is complex and costly. Utility Model Content

[0004] To address the shortcomings of existing technologies, this application provides a strengthening structure for improving the shear resistance of the ends of large-span frame beams. This structure overcomes the deficiencies of existing technologies and aims to solve the problems of concrete cracking and shear failure caused by shear force concentration at the beam ends of traditional frame beams under large-span conditions. Furthermore, conventional stirrup reinforcement methods are difficult to meet shear resistance requirements and are complex and costly to construct.

[0005] To achieve the above objectives, this application provides the following technical solution: a reinforcing structure for improving the shear resistance of the ends of large-span frame beams, comprising multiple sets of columns, with frame beams and crossbeams respectively provided on both sides of the multiple sets of columns. Insertion blocks are fixedly connected to the bottom of both ends of the frame beams. Insertion slots are provided on the top of the multiple sets of columns, and the insertion blocks are inserted into the insertion slots. Two sets of connecting bolts penetrating the column and the insertion blocks are provided on one side of each column. A fixing plate is provided on the side of the multiple sets of columns opposite to the frame beams. A reinforcing plate is provided on the top of the fixing plate, and the bottom of the reinforcing plate is fixedly connected to the top of the frame beams. The bottom of the reinforcing plate has the same slope as the top of the frame beams. Connecting plates are provided at both ends of the crossbeams, and the connecting plates are fixedly connected to the columns by bolts.

[0006] By adopting the above technical solution and setting up columns, the plug-in blocks at both ends of the frame beam can be directly inserted into the plug-in slots during use. The connecting bolts on both sides can effectively fix the plug-in blocks inside the plug-in blocks. The clamping plate on one side can achieve a tight connection between the frame beam and the fixing plate, and can provide a certain tensile force at the top of one end of the frame beam to cooperate with the plug-in blocks. During use, it can effectively balance the end shear force of the frame beam, improve the connection strength between the column and the frame beam, and effectively improve the shear resistance and stability during use.

[0007] As a preferred technical solution of this application, the column is provided with two sets of locking strips on the side near the fixing plate, the fixing plate is located between the two sets of locking strips, and a locking plate is provided at the bottom of the fixing plate, the locking plate being located at the bottom of the two sets of locking strips.

[0008] By adopting the above technical solution and setting the locking strips, the two sets of locking strips can fix the plate during use, which can better fix the fixing plate to one side of the column and achieve a more stable connection. The design of the two sets of locking strips allows the fixing plate to directly abut against one end of the frame beam, which can further fix the frame beam and improve practicality.

[0009] As a preferred technical solution of this application, the bottom of both sets of plug blocks is provided with multiple sets of reinforcing blocks, the top of the column is provided with a reinforcing groove, and the reinforcing blocks are installed inside the reinforcing groove.

[0010] By adopting the above technical solution and setting up reinforcing blocks, the connection between the plug-in block and the column can be further fixed during use, thereby improving the tightness of the overall connection and enhancing the stability during use.

[0011] As a preferred technical solution of this application, four sets of support plates are provided on the outer bottom of the column, and each of the four sets of support plates is provided with a stable base.

[0012] By adopting the above technical solution and setting up a support plate, a tighter connection between the column and the ground can be achieved during use, improving load-bearing capacity and stability during use.

[0013] As a preferred technical solution of this application, a supporting diagonal rod is provided at the bottom of the crossbeam, and the two ends of the supporting diagonal rod are fixedly connected to the crossbeam and the column, respectively.

[0014] By adopting the above technical solution and setting up supporting diagonal braces, a tighter connection between the beam and the column can be achieved during use, improving load-bearing capacity and practicality.

[0015] As a preferred technical solution of this application, a reinforcing diagonal brace is provided between the bottom of the frame beam and the column.

[0016] By adopting the above technical solution and setting up reinforcing diagonal braces, support can be provided to the bottom of the frame beam during use, further improving the shear resistance and enhancing practicality.

[0017] As a preferred technical solution of this application, multiple sets of crossbars are provided inside the multiple sets of frame beams, and the multiple sets of crossbars all pass through the multiple sets of frame beams.

[0018] By adopting the above technical solution and setting crossbars, the connection effect between multiple sets of frame beams can be improved during use, and deformation can be prevented when bearing load, thereby further improving the load-bearing capacity.

[0019] As a preferred technical solution of this application, triangular reinforcing ribs are provided at the bottom of the multiple sets of frame beams.

[0020] By adopting the above technical solution and setting triangular reinforcing ribs, the shear resistance of the frame beam can be improved at the bottom, thus enhancing its stability during use.

[0021] The beneficial effects of this application are: 1. By setting up columns, during use, the plug-in blocks at both ends of the frame beam can be directly inserted into the plug-in slots. The connecting bolts on both sides can effectively fix the plug-in blocks inside the plug-in blocks. The clamping plate on one side can achieve a tight connection between the frame beam and the fixing plate, and can provide a certain tensile force at the top of one end of the frame beam. It cooperates with the plug-in block and can effectively balance the end shear force of the frame beam during use, which can improve the connection strength between the column and the frame beam, and at the same time effectively improve the shear resistance and improve the stability during use.

[0022] 2. By setting the locking strips, two sets of locking strips can fix the plate during use, which can better fix the fixing plate to one side of the column and achieve a more stable connection. The design of two sets of locking strips allows the fixing plate to directly abut against one end of the frame beam, which can further fix the frame beam and improve practicality.

During use, it can effectively balance the end shear force of the frame beam 2, improve the connection strength between column 1 and frame beam 2, and effectively improve the shear resistance and stability during use. By setting up reinforcing block 202, during use, the fixation between the plug-in block 201 and column 1 can be further realized, improving the overall tightness of the connection and the stability during use.
