Abstract

The invention provides a new type of equipment and method for repairing cracks in wall boards with magnetic mortar. The method can repair cracks in floors and walls, especially internal cracks. Advantage. The attractive force inside the magnetic mortar can prevent the mortar from being washed away by the water flow. The magnetic mortar is guided by the attractor to increase the accuracy of the filling, reduce the influence of gravity on the gap filling in the horizontal direction, improve the utilization rate of the mortar, save materials and Increased the compactness of the mortar in the gap. At the same time, through the grouting conduit, the deep small cracks are filled in sections to improve the filling degree of the cracks and reduce the possibility of re-expansion of internal cracks and water leakage again in the later stage.

Description

technical field [0001] The invention relates to a device and a method for repairing cracks in wall boards with magnetic mortar, and belongs to the technical field of repairing cracks in wall and floor building structures. Background technique [0002] In the daily use of new houses and some old houses, for these buildings where most of the walls and floors are made of concrete, cracks and appearances caused by insufficient floor thickness, poor concrete ratio, and excessive construction speed Water leaks after cracks are common and frequent. [0003] At present, most of the crack repair methods adopted are to apply waterproof paint on the surface of the floor, paste the steel plate on the surface, or use a syringe to pour resin adhesive into the crack. However, surface repair cannot repair the interior of cracks, and can only prevent further damage to internal concrete and steel bars by water vapor and carbon dioxide substances; adding steel plates to the outside of concret...
