Description

Technical Field

[0001] The utility model relates to the technical field of crack repair, in particular to a novel roof caulking glue injection device. Background Art

[0002] The existing material for repairing roof cracks is usually cement mortar. Since cement mortar materials are prone to shrinkage and cracking, wall and roof cracks repaired with cement mortar are prone to secondary cracking. Therefore, workers use the cement mortar painting process. After the cracks are filled, they sometimes need to use waterproof materials to strengthen the treatment of leaks and cracks.

[0003] Another roof repair technology is to use asphalt mortar as the caulking repair material, but because asphalt will solidify at room temperature, the nozzle used to spray asphalt mortar will be blocked if it is not cleaned in time after use, affecting the next use.

[0004] Due to the property that asphalt mortar will solidify at room temperature, it usually cannot penetrate into the deep cracks by itself when sprayed with a nozzle to repair deeper cracks. In addition, in order to ensure the same thickness of the asphalt mortar applied, a roller coating device is often set at the bottom of the device. During the rolling process of the roller coating device, the asphalt mortar adhered to the surface of the roller coating device will solidify on the surface of the roller coating device, affecting the normal operation of the roller coating device.
