Embodiment Construction

[0018] The present embodiment will be described in detail below in conjunction with the accompanying drawings.

[0019] In this embodiment, two concrete girders are arranged in the middle of the inner wall, the first concrete girder 1 is set at a height of three quarters of the floor 8, and the second concrete girder 2 is set at a quarter of the floor 8 Layer height. The height of the concrete girder is 200mm, and the width is 60-80mm larger than the width of the inner wall. The width of the concrete girder is 60-80mm larger than that of the inner wall. A fixing hole is set in the middle of the protruding part of the concrete girder, and the depth of the fixing hole is 70-90mm. The diameter of the fixing hole is 16-18 mm, and the fixing hole is inserted into the fixing rib 5. The diameter of the fixing rib 5 is 12-14 mm, and the spacing of the fixing rib 5 along the horizontal direction is 50-70 mm. Set prestressed tendons 3 on the surface of the inner wall at a distance of 3...

Abstract

The invention discloses a reinforcement construction method for a cracked internal wall. The reinforcement construction method for the cracked internal wall is characterized in that (1) a steel support is arranged on a floor; (2) mortar covering the surface of the internal wall is peeled off; (3) a first concrete small beam and a second concrete small beam are formed; (4) reserved holes are drilled in an external wall; (5) cushion steel bars are welded onto constructional column hoops, a pressure-bearing steel plate is welded onto the cushion steel bars, and an anchoring plate is welded on the outer surface of the pressure-bearing steel plate; (6) prestress ribs are fixed to the pressure-bearing steel plate through the anchoring plate, and then tensioned; (7) a steel bar mesh is hung on the surface of the wall; (8) fine aggregate concrete is sprayed through a pressure spray gun; and (9) the wall is brushed withcement mortar, and leveling is conducted.

Description

technical field [0001] The invention relates to a reinforcement construction method for an inner wall with cracks, which is suitable for the construction field. Background technique [0002] Cracks will appear on the inner wall of the building during use. The reasons for the analysis may be as follows: 1. The load of the upper structure exceeds the bearing capacity of the inner wall of the building; 3. The influence of temperature stress or settlement stress on the inner wall of the building. Under the above circumstances, there will be splayed cracks on the inner wall of the building, especially vertical cracks are prone to appear at the junction of the inner wall and the outer wall of the building, and even the outer wall will have a tendency to flash outward. Whether it is for safety performance or use function considerations, reinforcement must be carried out, but the current traditional reinforcement method is to hang steel mesh, which does not improve the mechanical p...
