Embodiment Construction

[0016] Such as Figure 1 to Figure 3 As shown, the steel plate support and reinforcement RC frame-inner filling wall structure of the present invention includes frame beam 1, frame column 2 and inner filling wall 5, steel bars 3 are respectively installed on both sides of frame beam and frame column, each steel bar There are bolt holes on the top, and every two steel bars are connected by tie rods 4; the steel bars on the inside of the frame beam and frame column are welded vertically with the channel steel 8; the inner filling wall is built inside the frame; the channel steel 8 and the profiled steel plate 7 are supported Attach by self-tapping screws 6.

[0017] In a further embodiment, the profiled steel plate can also be herringbone, figure eight or X shape, which will not be illustrated for example.

[0018] The method for strengthening the RC frame structure through the above-mentioned reinforcement structure comprises the following steps:

[0019] a. Put the steel bar...

Abstract

The invention discloses an RC frame-internal infilled wall structure with a profiled steel sheet support and a reinforcing method. The reinforcing structure comprises rectangular frame units composed of frame beams and frame columns, internally infilled walls built inside the rectangular frame units, steel bars arranged along the internal peripheral walls and the external peripheral walls of the rectangular frame units, pull rods used for connecting and fixing the steel bars on the internal peripheral walls and steel bars on the external peripheral walls, a plurality of pieces of box iron welded to the steel bars, and a profiled steel sheet with the two ends respectively connected to the box iron in a screw joint mode. The reinforcing structure is composed of the profiled steel sheet, the steel bars, the pull rods, the box iron and the internal infilled walls, and therefore the rigidity of the frame is improved, the energy-dissipating capacity of the frame is enhanced, the frame can resist the horizontal load better, and the reinforcing structure has the advantages of being simple, convenient to operate and construct and the like.

Description

technical field [0001] The invention relates to an anti-seismic structure, especially a reinforced RC frame-inner filling wall structure with profiled steel supports. Background technique [0002] Due to the advantages of flexible building layout and large indoor space, RC frame structures are widely used in the architectural structures of teaching buildings in primary and secondary schools. However, in the 5.12 Wenchuan earthquake, this form of primary and secondary school teaching buildings suffered varying degrees of damage. This damage shows that the RC frame structure has the defects of small lateral stiffness and low horizontal resistance. [0003] Therefore, technical innovation is required to solve the above problems. Contents of the invention [0004] Purpose of the invention: To provide a reinforced RC frame-infill wall structure supported by profiled steel plates, and further provide a reinforcement method to solve the problems of low lateral stiffness and low...
