Embodiment Construction
[0023] figure 1 It is a schematic diagram of the facade of the brick-column reinforced structure, figure 2 Schematic diagram of the cross-section of the brick-column-reinforced structure, image 3 It is a schematic diagram of the steering steel block structure. In the embodiment, after the surface of the brick column 1 is cleaned and painted with mortar, two prestressed tendons 3 are hung. The diameter of the prestressed tendons 3 is 22 mm. 1 height, the section length of brick column 1 is 400mm, and the distance between two prestressed tendons 3 is 100mm. A turning steel block 2 is set at the turning point where the vertical section of the prestressed tendon 3 becomes an oblique section. The steering steel block 2 is composed of a steel backing plate 9 and a reinforcing bar 10. The round steel, the pad steel bar 10 and the prestressed tendon 3 contact parts are polished according to the turning arc of the prestressed tendon 3, so that the prestressed tendon 3 is in surfac...

The invention discloses a brick column reinforcement method. The method is characterized in that two prestress ribs are hung after the surface of a brick column is cleaned and coated with mortar, the middle sections of the stress ribs are vertically distributed, the length of the middle sections of the prestress ribs is 0.45-0.55 time of the height of the brick column, steering steel blocks are arranged on the turning portions where the vertical sections of the prestress ribs are changed into inclined sections, steel inserted plates are inserted into vertical mortar joints of the brick column, angle steel is arranged on the portion 250-300 mm away from the end of the brick column, the angle steel is inserted into transverse mortar joints of the brick column, and the prestress ribs are fixed to the angle steel through anchors after being tensioned. Shotcrete is arranged on the outer sides of the prestress ribs. Expansive concrete is adopted as the shotccrete, steel batten plates are arranged on the outer sides of the expansive concrete and are welded to U-shaped embedded parts buried in the brick column, and the width of the steel batten plates is 150-200 mm.
Description
technical field [0001] The invention relates to a reinforcement method, in particular to a brick column reinforcement method. Background technique [0002] When the bearing capacity of the brick column is not enough, it needs to be reinforced. The traditional reinforcement method is to increase the section method. Since the original structure is under stress, stress and strain have already occurred, and the added structure has no stress and strain, resulting in the original structure. The inconsistency of stress and strain between the body and the added structure makes it difficult for the added structure to form a whole with the original structure. It is necessary to improve this, and apply a certain prestress to the added structure to make it produce stress and strain, which is conducive to the coordination of the original structure and the added structure. SUMMARY OF THE INVENTION [0003] The invention provides a brick column reinforcement method, which solves the pro...
