Description

Technical Field

[0001] The utility model relates to the technical field of building construction, in particular to a steel-bonded reinforcement structure for a beam end meeting a shear wall. Background Art

[0002] For the traditional steel-bonded reinforcement of a frame beam, that is, a steel section is used to wrap the outside of the frame beam to form a reinforcement structure for enhancing the structural strength and load-bearing capacity of the frame beam. However, at the intersection position of the frame beam and the shear wall, since the shear wall is a very wide plane, the steel section wrapped outside the frame beam cannot completely wrap the shear wall, reducing the structural strength of the beam end part meeting the shear wall. If the steel section wraps the shear wall, it will greatly increase the construction cost, construction difficulty and construction period, which is uneconomical. Therefore, it is necessary to provide a steel-bonded reinforcement structure for a beam end meeting a shear wall, which can solve the problem of reduced structural strength of the beam end part of the shear wall in the prior art. Summary of the Invention

[0006] The connecting angle steel and the bonding plate on the beam surface located on the top surface of the frame beam are fixed by a plurality of expansion bolts and a plurality of implanted screws, and the expansion bolts and the implanted screws are arranged alternately and fixed into the frame beam.

[0007] The depth of the implanted screw implanted into the frame beam is not less than 200 mm.

[0008] The distance between the first implanted screw and one end of the bonding plate on the beam surface and the wall surface of the shear wall is 250 mm, and the distance between the last implanted screw and the other end of the bonding plate on the beam surface is 50 mm.

[0009] The steel section wrapped outside the beam described above includes a beam bottom plate attached to the bottom surface of the frame beam, beam side plates attached to the two side surfaces of the frame beam, several U-shaped hoop plates arranged around the beam bottom plate and the beam side plates, and a reinforcement plate connecting the several U-shaped hoop plates; the beam surface bonding plates located on both sides of the frame beam are welded and fixed to the reinforcement plate.

[0010] The arrangement spacing of the U-shaped hoop plates within the length range of the beam surface bonding plate is smaller than that of the U-shaped hoop plates outside the beam surface bonding plate.

[0011] The depth of the tensile rebar implanted into the shear wall is not less than 15 times the diameter of the tensile rebar.

[0031] Please refer to the appendix Figure 1 Please refer to the appendix

[0032] The arrangement spacing of the U-shaped hoop plates 23 within the length range of the beam surface bonding plate 3 is smaller than the arrangement spacing of the U-shaped hoop plates 23 outside the beam surface bonding plate 3.

[0033] The depth of the tensile anchor bar 4 implanted into the shear wall 6 is not less than 15 times the diameter of the tensile anchor bar 4. The implantation depth of the tensile anchor bar 4 can be adjusted adaptively according to the actual construction requirements to ensure the connection reliability between the connecting angle steel 5 and the shear wall 6, thereby providing a strengthening effect for the connection node where the frame beam 1 meets the shear wall 6.

[0034] Please refer to the appendix Figure 3 Please refer to the appendix

[0035] The length of the connecting angle steel 5 located at the top of the frame beam 1 is greater than the width of the frame beam 1, so that both ends of the connecting angle steel 5 extend out of both sides of the frame beam 1.Preferably, the connecting angle steel 5 can be L110*8 angle steel. The two ends of the connecting angle steel 5 respectively extend 50 mm deep into both sides of the frame beam 1.

The installation methods of the connecting angle steels 5 on both sides of the frame beam 1 are the same and the positions are symmetrical, which will not be elaborated here. When installing the connecting angle steels 5 on both sides of the frame beam 1, pay attention to avoiding interference with the connecting angle steel 5 at the top.

[0042] After installation, the beam end of the frame beam 1 and the shear wall 6 are connected into a whole through the beam surface bonding plate 3, the tensile anchor bars 4 and the connecting angle steel 5, so as to improve the connection joint strength when the beam end of the frame beam 1 meets the shear wall 6.
