Embodiment 1

[0038] refer to figure 1 , shows a flow chart of the reinforcement method for the reinforced concrete frame structure described in Embodiment 1 of the present application, and the method includes:

[0039] Step S101, determining the reinforcement space of the reinforced concrete frame structure, the reinforcement space is located below the outdoor floor where the reinforced concrete frame structure is located.

[0040] The embodiment of this application adopts the indirect reinforcement method to strengthen the reinforced concrete frame structure. When strengthening, firstly determine the reinforcement space. In this embodiment, the reinforcement space of the reinforced concrete frame structure is set below the outdoor floor where the frame structure is located, that is, the reinforcement space It is located on the outside of the frame structure (that is, outside) and below the level of the outdoor floor.

[0041] Step S102, in the reinforced space, a concrete wall is set at ...

Embodiment 2

[0052] refer to figure 2 with image 3 , respectively show a cross-sectional schematic view and a schematic plan view of the reinforced concrete frame structure in this embodiment.

[0053] In this embodiment, the connection beam of the reinforced concrete frame structure is located above the top surface of the independent foundation of the reinforced concrete frame structure, that is, the connection beam and the independent foundation are arranged independently of each other, and the connection beam is located above the entire independent foundation. Near the indoor floor, the specific location can be found in figure 2 . The elevation of the indoor floor 11 where the frame structure is located is equal to the elevation of the outdoor floor 12. The height from the indoor floor 11 to the top surface of the first-floor roof of the frame structure is 3600mm, the embedding depth of the independent foundation 2 is 1500mm, and the height of the independent foundation 2 is 500mm, ...

Embodiment 3

[0069] refer to Figure 4 with Figure 5 , respectively show a cross-sectional schematic view and a schematic plan view of the reinforced concrete frame structure in this embodiment.

[0070] The difference between this embodiment and the second embodiment above is that the top surface of the connecting beam 6 of the reinforced concrete frame structure is flush with the top surface of the independent foundation 2 of the reinforced concrete frame structure.

[0071] Therefore, if the method described in the third embodiment is used to reinforce the reinforced concrete frame structure, then according to the position of the connection beam 6 of the concrete frame structure described in the reinforcement method, the top of the concrete wall 4 and the steel bar The steps of setting concrete beams 3 between the frame columns 1 of the concrete frame structure include:

[0072] Concrete beams 3 are arranged between the top of the concrete wall 4 and the outermost frame columns of th...

Abstract

The invention discloses a strengthening method for a reinforced concrete frame structure. The strengthening method comprises the following steps of: determining a strengthening space of the reinforced concrete frame structure, wherein the strengthening space is located under an outdoor terrace on which the reinforced concrete frame structure is located; installing a concrete wall at preset intervals apart from frame columns of the reinforced concrete frame structure in the strengthening space; and installing a concrete beam between the top end of the concrete wall and the frame columns of the reinforced concrete frame structure according to the position of a connecting beam of the reinforced concrete frame structure, wherein the concrete wall and the concrete beam are used for strengthening the reinforced concrete frame structure together. According to the strengthening method disclosed by the invention, earthquake borne by the frame structure is effectively relieved, the earthquake response of the structure is reduced, and the earthquake resistant behavior of the reinforced concrete frame structure is improved.

Description

technical field [0001] The present application relates to the technical field of building structure reinforcement, in particular to a reinforcement method for a reinforced concrete frame structure. Background technique [0002] Frame structure refers to the structure of the load-bearing system composed of frame beams and frame columns connected by rigid joints or hinges, that is, the frame composed of frame beams and frame columns jointly resists horizontal loads and vertical loads that occur during use. The walls of houses with frame structure are not load-bearing, and only play the role of enclosure and separation. The frame structure has the advantages of flexible layout and light weight, and is widely used in industrial and civil buildings in our country. [0003] At present, the reinforcement methods for reinforced concrete frame structures can generally be divided into direct reinforcement methods and indirect reinforcement methods. [0004] The direct reinforcement ...
