SUMMARY

[0003] The utility model solves the technical problem in the above background technical field to provide a building reinforcing device.

[0004] The utility model discloses a technical scheme:

[0005] A building reinforcing device, including steel pull plate and a plurality of expansion screw bushings, the steel pull plate rear face along the center line symmetry is seted up main grouting groove, and is seted up with the grouting hole of the communication of main grouting groove on the steel pull plate front face, the steel pull plate rear face is located main grouting groove both sides symmetry and is welded with a plurality of groups of expansion screw bushings, the steel pull plate is seted up annular grouting groove around expansion screw bushing, and annular grouting groove is connected to main grouting groove respectively through the drainage channel.

[0006] Further, the depth of the annular grouting groove, the main grouting groove and the drainage channel is consistent, which is 3-4mm, and the thickness of the steel pull plate is 10-12mm.

[0007] Further, the expansion screw bushing is composed of an expansion section and a constant diameter section, the peripheral wall of the top end of the constant diameter section is welded integrally with the steel pull plate, the peripheral wall of the expansion section is composed of a plurality of intersecting spherical surfaces, and the expansion opening is vertically formed on the peripheral wall of the expansion section.

[0008] Further, the diameter of the spherical surface of the peripheral wall of the expansion section is greater than the diameter of the constant diameter section, and the diameter of the annular grouting groove is greater than the diameter of the spherical surface of the peripheral wall of the expansion section.

[0009] The utility model has the advantages that:

[0010] The utility model reinforces the position of the crack by the cooperation and traction of the steel pull plate and the expansion screw bushing, which has greater strength compared with the simple grouting, the steel pull plate has the main grouting groove and the annular grouting groove on the inner side, forms a relatively closed structure, can simultaneously fill the grouting in the gap of the wall surface and the gap between the drill hole and the expansion screw bushing, thereby greatly reducing the difficulty of grouting and enhancing the reinforcing capacity. BRIEF DESCRIPTION OF DRAWINGS

[0011] Figure 1The utility model discloses a three-dimensional structure schematic diagram.
