Detailed ways

1 and 2, the present embodiment provides a masonry brick wall steel plate reinforcement structure, which includes a masonry brick wall body 1, a vertical steel plate belt 2, a pair of tension members 3, a vertical angle steel 4, and a horizontal steel plate Belt 5 and horizontal steel bead 6. The tension member 3 includes a bolt and a nut matched with the bolt.

A plurality of vertical steel plate strips 2 are arranged vertically and side by side on both surfaces of the masonry brick wall 1, the vertical steel plate and the masonry brick wall 1 are penetrated through a drilling process, and then the bolts are passed through the vertical The steel plate strip 2 and the masonry brick wall 1 are then screwed with nuts on the bolts, so as to realize the connection, tension and fixation of the vertical steel strips 2 on the two surfaces of the masonry brick wall 1 .

A horizontal steel plate bead 6 is symmetrically arranged on the top and bottom of the masonry brick wall 1 respectively. The horizontal steel plate bead 6 is pressed against the end of the vertical steel plate strip 2. Drill holes in the overlapping part of the machine, penetrate the overlapping part and the masonry brick wall 1, then pass the bolts through the overlapping part and the masonry brick wall 1, and then screw the nuts on the bolts to realize the installation of the masonry brick wall. The overlapping parts on the two surfaces of the body 1 are connected and fixed by pulling.

Two vertical angle steels 4 are arranged at the vertical corners of the masonry brick wall 1, that is, the vertical angle steels 4 are installed at both ends or corner positions of the masonry brick wall 1, and the inner corners of the vertical angle steels 4 are installed. The surface is in contact with the outer corner surface at the vertical corner of the masonry brick wall 1 .

A plurality of horizontal steel plate strips 5 are arranged horizontally and side by side on both surfaces of the masonry brick wall 1, and the two ends of each horizontal steel plate are symmetrically and horizontally extended to the vertical steel plate strip 2 near its one end, and then connected by welding. The horizontal steel plate belt 5 is staggered in the middle part of the vertical steel plate belt 2 to drill holes, the middle part and the masonry brick wall 1 are penetrated, and then the bolts are passed through the middle part and the masonry brick wall 1, and then the The nuts are screwed on the bolts, so as to connect and pull and fix the middle parts on the two surfaces of the masonry brick wall 1 . Preferably, there are also raised ribs on the surface of the horizontal steel plate facing the masonry brick wall 1, a plurality of raised ribs are arranged at intervals, and the interval between two adjacent raised ribs forms a space for the vertical steel plate belt 2 to pass through. The height of the rib is slightly larger than the thickness of the vertical steel plate strip 2 , so that the rib can slightly sink into the brick joints of the masonry brick wall 1 and cooperate with the masonry brick wall 1 more closely.

After the installation is completed, anti-rust and anti-corrosion treatment is carried out. Specifically, anti-rust paint is sprayed on the vertical steel plate belt 2, the tension member 3, the vertical angle steel 4, the horizontal steel plate belt 5 and the horizontal steel plate bead 6 to form an anti-rust paint layer.
