Description

Technical Field

[0001] The utility model relates to the technical field of frame beam construction, in particular to a frame beam structure with an enlarged cross-section. Background Art

[0002] A frame beam refers to a beam connected to a frame column at both ends. In a frame structure, it is mainly used to directly bear the load of the roof and transfer it to the frame column. In addition, it has another important function, which is that it is rigidly connected with the frame column to form a beam-column lateral force resistance system to jointly resist horizontal forces such as wind loads and earthquakes. At the same time, during the construction process, there is often a need to reinforce the frame beam. Among them, the cross-section reinforcement method is more commonly used, that is, a reinforcement method that increases the cross-sectional area of the concrete structure or structure to increase its bearing capacity and meet normal use.

[0003] In the prior art, when the cross-section enlargement reinforcement method is adopted, if only one side can be enlarged and the stirrups are difficult to weld with the original beam stirrups, the cross-section enlargement work becomes difficult to carry out. Therefore, a frame beam cross-section enlargement structure is proposed to solve the above problem. Utility Model Content

[0004] In order to solve the above technical problems, the utility model proposes a frame beam with an enlarged cross-section structure. By opening a hole in the plate on the side of the original structural beam, an accommodating groove is opened on the side of the structural beam. After the inverted U-shaped stirrups are passed through, the inverted U-shaped stirrups are welded to the positive U-shaped stirrups on one side from the bottom to form a casting frame, thereby achieving the purpose of enlarging the structural beam on one side.

[0005] The technical solution for achieving the purpose of the utility model is: a frame beam with an enlarged cross-section structure, including a receiving groove and an inverted U-shaped stirrup opened on one side of the original structural beam, the bottom end of the inverted U-shaped stirrup passes through the floor slab and is partially located in the receiving groove, the surface of the inverted U-shaped stirrup is fixedly connected with a positive U-shaped stirrup, and also includes a newly added surface reinforcement arranged on one side of the original structural beam, the newly added surface reinforcement is fixedly connected to the inverted U-shaped stirrup, and also includes a newly added bottom reinforcement arranged at the bottom of the original structural beam, the newly added bottom reinforcement is fixedly connected to the positive U-shaped stirrup.

[0006] In some embodiments, the newly added surface reinforcement and the newly added bottom reinforcement are both fixed to the original structural wall, and the distance between the newly added surface reinforcement, the newly added bottom reinforcement and the original structural wall forms an enlarged cross-sectional area.

[0007] In some embodiments, a tie bar is provided at the connection between the newly added reinforcement and the inverted U-shaped stirrup, the tie bar is hook-shaped, and one end of the tie bar is connected to the original structural beam.

[0008] Compared with the prior art, the present invention has the following significant advantages:

[0009] The utility model roughens the surface of the original structural beam, opens a hole in the plate on the side of the original structural beam, opens an accommodating groove on the side of the structural beam, passes the inverted U-shaped stirrup through, and then welds the inverted U-shaped stirrup and the normal U-shaped stirrup from the bottom on one side, and then gradually installs the new surface reinforcement and the new bottom reinforcement, and welds the new surface reinforcement to the inverted U-shaped stirrup, and welds the new bottom reinforcement to the normal U-shaped stirrup, finally forming a casting frame with an increased cross-section, and then supports the formwork, and uses a higher-level strength self-compacting fine stone concrete for casting, so that the construction of increasing the cross-section on one side can be completed, and at the same time, safety and economy can be guaranteed;

[0010] The invention solves the problem that the newly added reinforcement cannot be welded to the original beam stirrups when the existing frame beam has a single-side enlarged cross-section. BRIEF DESCRIPTION OF THE DRAWINGS
