Building outer wall aging repairing device and repairing method

Abstract

The invention belongs to the technical field of building outer wall repairing, and particularly relates to a building outer wall aging repairing device and repairing method. The building outer wall aging repairing device comprises a machine box, a display mechanism and a hoisting mechanism, wherein the display mechanism and the hoisting mechanism are arranged on the two sides of the top end of themachine box correspondingly; the display mechanism comprises a supporting rod, a rotating shaft and a display screen; the supporting rod is located at the top end of the machine box and is in screw joint and fixed to the machine box; the display screen is located at the top end of the supporting rod; a bearing mechanism is additionally arranged at the bottom end of a spraying device; the bearingmechanism drives a bearing box to move left and right through a moving air cylinder to be attached to the wall face and used for bearing broken wall skin scraped off during wall face spraying repairing and spraying scattered spraying materials, the situation of object falling from high altitudes is avoided, and the stability and safety of high-rise building outer wall face repairing are enhanced;and a servo motor used for driving a stirring shaft to rotate is arranged, materials in a coating containing cavity can be stirred and mixed, the situation that coating is solidified due to long-timestanding is avoided, and the uniformity of the spraying materials is enhanced.

Description

technical field [0001] The invention belongs to the technical field of repairing exterior walls of buildings, and in particular relates to an aging repairing device and a repairing method for exterior walls of buildings. Background technique [0002] At present, the water seepage problem of the outer wall of the construction industry is a common phenomenon, especially in the buildings in areas with large rainfall such as coastal areas, the water seepage problem is particularly prominent. At present, the waterproof method of the outer wall of the building mainly includes pasting ceramic tiles on the surface of the outer wall (such as outer wall tiles and paper bricks), or paint directly on the exterior wall. Although these waterproof methods can increase the aesthetics of the exterior wall, it is difficult to ensure fullness of the mortar when laying bricks manually, and it is also difficult to achieve fullness when filling the joints. The wall and wall tiles will crack when...

AI Technical Summary

Problems solved by technology

Although these waterproof methods can increase the aesthetics of the exterior wall, it is difficult to ensure fullness of the mortar when laying bricks manually, and it is also difficult to achieve fullness when filling the joints. Walls and wall tiles will crack when they expand and contract. Over time, the cracks will become larger and larger, and water seepage is difficult to avoid.

In addition, because the thermal expansion coefficients of the exterior wall bricks and mortar are different, and the temperature of the exterior wall of the building changes greatly, especially in areas with a large temperature difference between day and night, the exterior wall bricks and mortar are easy to separate and fall off, which easily leads to accidents.
