Embodiment Construction

[0029] Such as figure 1 , figure 2 and image 3 As shown, the first embodiment of the present invention is introduced.

[0030] In this embodiment, the fully spliced ​​concrete frame reinforcement device mainly includes channel steel 1, angle steel 4, tension screw 2, chemical anchor bolt 3 and strip 5, and its position is as follows image 3 shown. In this embodiment, for the convenience of description, the cavity in the channel steel used to wrap the concrete column is called the inside, and the cavity opposite to it is called the outside.

[0031] go to figure 1 , specifically describe the shape of the channel steel. The cross-section of the channel steel is generally in the shape of an oval, and the end is bent outward to form a flange portion, and a through hole 1b is provided on the flange portion and the side of the channel steel. The flange part is parallel to the central axis of the channel steel, and when the channel steel is fixed on the concrete column, the ...

Abstract

The invention discloses a full-assembled concrete frame reinforcing apparatus and a construction method thereof. The full-assembled concrete frame reinforcing apparatus comprises steel channels, steel angles, tie bolts, chemical bolts and lacing bars. The cross section of the steel channels is approximately U shaped, and an end of each steel channel is bent out, forming a flange portion with which steel channel lateral faces are provided with through holes; the steel angles are fixedly connected with the steel channels; the cross section of the steel angles is approximately L shaped, and lateral ribs are provided with lugs; the tie bolts penetrate through holes in the flange portions to fixedly connect the adjacent steel channels; two ends of each lacing bar are fixed to the lugs of the adjacent steel angles, respectively. In the above scheme, prefabrication is suited to the steel channels, the steel angles and the like, full bolt assembly is carried out in situ, construction efficiency is high, and a construction site is highly civilized; the ends of the steel channels are clamping functional, so that a concrete column is stressed from three directions and compression resistance of the concrete column can be given to full play.

Description

technical field [0001] The invention belongs to the field of building engineering, in particular to a device or method for repairing or strengthening existing building structures. Background technique [0002] The reinforcement and repair of damaged buildings after strong earthquakes is an engineering problem that needs to be solved urgently. There are currently several traditional strengthening methods, including enlarged section method, external formwork method and outsourcing steel method. [0003] However, there are still some defects in the existing methods, such as low construction efficiency and poor synergistic performance. Contents of the invention [0004] Purpose of the invention: One purpose is to provide a fully spliced ​​concrete frame reinforcement device to solve the above-mentioned problems in the prior art. A further object is to provide a construction method for the above-mentioned fully spliced ​​concrete frame reinforcement device. [0005] Technica...
