Embodiment
[0037] In specific implementation, such as figure 1 and figure 2 As shown, first, use visual inspection, tapping method, and infrared measurement method to determine the hollow area with the original construction records; then select the hollow area larger than 1.5 times as the repair range, and the anchor bolts are arranged in a plum blossom shape at 25 to 30 square meters per square meter. The anchor bolts usually selected are thermal insulation expansion anchor bolts with washers, the effective anchoring depth of the anchor bolts is not less than 25mm, and the diameter of the plastic washers is not less than 50mm; Deep into the base of the building; then, use a dust blower or an air pump to blow away the debris in the anchor hole; after that, lay the reinforced alkali-resistant mesh in the determined repair range, and use an electric drill to screw the stainless steel screws And the plastic washer is pressed and installed in the casing of the matching brand and model,...

The invention discloses a mechanical repair method and structure for hollowing of external wall thermal insulation mortar. Mark the required anchor bolt holes within the repair scope; step 4 drill the anchor bolt holes and clean the dust and impurities in the anchor bolt holes; step 5 press the adiabatic expansion anchor bolt hose into the anchor bolt holes; step 6 repair the outer wall Lay reinforced alkali-resistant mesh cloth within the area, and mechanically anchor the reinforced alkali-resistant mesh cloth through anchor bolts; step 7 Use superelastic putty to perform surface treatment on the outer wall repair area. The invention utilizes thermal insulation expansion bolts with washers to press the reinforced alkali-resistant mesh cloth into the wall, under the premise of ensuring the original thermal performance of the wall, the impact on the surrounding thermal insulation mortar is small, and the connection with the base wall is firm. Safe and reliable. At the same time, it will not damage the insulation layer, effectively reduce the rework period, and has strong economical practicability.
Description
technical field [0001] The invention relates to a mechanical repair method and structure for hollowing of external wall thermal insulation mortar, and belongs to the technical field of building external wall repair. Background technique [0002] During the construction of building exterior wall insulation mortar, due to reasons such as workers or materials, it often occurs that the insulation mortar and the concrete foundation wall are not bonded firmly, cracking occurs, and a gap appears between the concrete foundation wall and the insulation mortar, commonly known as void. Drumming or shelling. At present, when the hollowing phenomenon of the external wall is repaired, the insulation mortar layer of the peeling part is generally cut off, and the insulation mortar layer is repainted. After the insulation mortar has strength, the anti-cracking mortar layer is constructed. The current repair method takes a long time, consumes a lot of materials, affects the construction p...
