Abstract
Description
Technical Field
[0001] The utility model relates to a reinforcement structure, in particular to an eccentric beam-column building reinforcement structure, belonging to the technical field of concrete buildings. Background Art
[0002] According to the relevant provisions of the Technical Code for Concrete Structures of High-rise Buildings JGJ 3-2010 and the Code for Seismic Design of Buildings GB50011-2010 (2016 edition), when the center lines of frame beams and columns cannot coincide, the adverse effects of this eccentricity on the stress and structure of the core area of the beam-column node, as well as the eccentricity of the beam load on the column, should be considered in the calculation. Although measures such as adding horizontal axils to the beams can be taken when the eccentricity is greater than 1 / 4 of the column width in that direction, the adverse effects of beam-column eccentricity must still be considered after the horizontal axils are set. Therefore, it is necessary to use horizontal axils when the eccentricity of the beam and column is greater than 1 / 4 of the column width in that direction. However, there are design oversights or omissions in construction during the specific implementation, which have had varying degrees of impact on the safety of the structure. Attached to the instruction manual Figure 1 The horizontal axil structure diagram of the frame beam in the prior art to deal with the eccentricity is shown in the figure. This method has the disadvantages of a large number of steel bars to be tied and the need to set up corresponding templates, and the construction process is cumbersome and labor-intensive. Therefore, further improvement is needed. Utility Model Content

[0004] In order to achieve the above purpose, the utility model adopts the following technical solutions:
[0005] An eccentric beam-column building reinforcement structure comprises an eccentrically arranged frame beam and column, and also comprises a reinforcement seat body arranged at the intersection angle of the frame beam and column; the reinforcement seat body is connected to the frame beam and column respectively through fasteners; and a plurality of reinforcing members are arranged in the reinforcement seat body.
[0006] Furthermore, the reinforcement seat body includes a first anchor plate and a second anchor plate; the angle between the first anchor plate and the second anchor plate is consistent with the angle at the intersection of the frame beam and the column; the first anchor plate and the second anchor plate are respectively attached to the frame beam and the column.
[0007] Furthermore, a plurality of fixing holes are provided on the first anchor plate and the second anchor plate; and pre-formed holes are provided on the surfaces of the frame beams and columns relative to the fixing holes.
[0008] Furthermore, the first anchor plate and the second anchor plate are fixed to the frame beam and the column respectively through anchor bolts and nuts.
[0009] Furthermore, the first anchor plate is fixed to the frame beam by means of through-type anchor bolts and nuts; and structural adhesive is also provided between the first anchor plate and the second anchor and the frame beam and column.
[0010] Furthermore, the reinforcement member is a fan-shaped reinforcement steel plate; the fan-shaped reinforcement steel plate is connected between the first anchor plate and the second anchor plate and is distributed along the height direction thereof.

However, this solution can be reinforced after pouring is completed and the construction formwork is removed, which simplifies the construction process and reduces construction costs.
