Description

Technical Field

[0001] The utility model specifically relates to a waterproof cloth laying device and belongs to the technical field of waterproof cloth laying. Background Art

[0002] In order to prevent water from penetrating into buildings, buildings are waterproofed, which is usually solved by laying waterproof cloth. Building waterproof cloth is usually laid on the roof of the building, mainly used to prevent rainwater and snow water from penetrating into the roof. Building waterproof cloth is generally rolled into bundles before installation. When laying, the waterproof cloth is slowly released through the waterproof cloth laying device to make the waterproof cloth fit closely with the roof surface, thereby increasing the service life of the building.

[0003] As disclosed in the publication number CN220203227U, a construction tarpaulin deployment device comprises a mounting frame, wherein the mounting frame comprises a first mounting frame in a vertical direction and a second mounting frame horizontally mounted below the first mounting frame, both sides of the inner wall of the first mounting frame are rotatably connected with rotating wheels, a tarpaulin is wound between the rotating wheels, an end of the second mounting frame away from the first mounting frame is movably connected with a fixing frame, a pressing roller is rotatably connected inside the fixing frame, and casters are fixedly mounted on both sides below the first mounting frame. The utility model improves the deployment efficiency and reduces the workload of the operator by arranging the rotating wheels, casters and the first mounting frame, and by arranging the pressing roller, after the tarpaulin is released, the occurrence of missed compacted parts is avoided, thereby improving the deployment quality and work efficiency.

[0004] When using a common tarpaulin laying device, although a pressing roller can be set to press the tarpaulin so that it is in close contact with the roof surface, thereby improving the laying quality, the position of the pressing roller is fixed. When laying tarpaulins of different thicknesses, the tarpaulin will be too close to the ground and affect movement, or will not be in close contact with the ground and affect the laying quality. In addition, the tarpaulin is prone to slight tilt when released, and is generally straightened manually, which is inconvenient and inefficient. Utility Model Content
