Small coiled material automatic unrolling trolley and method for unrolling coiled material

Abstract

The invention relates to the technical field of building construction, in particular to a small coiled material automatic unrolling trolley and a method for unrolling a coiled material. The small coiled material automatic unrolling trolley comprises a moving chassis. One end of the moving chassis is connected with a traction advancing mechanism, and the other end of the moving chassis is connected with a coiled material laying-pressing mechanism. The coiled material laying-pressing mechanism comprises a laying-pressing platform connected with the moving chassis. The lower end of the laying-pressing platform is in coupling connection with a laying through roller. A coiled-material-wound storing roller is erected on the laying-pressing platform through a storing support. One end of the coiled material is wound around the storing roller, and the other end of the coiled material covers the laying through roller and is pressed on the ground through the bottom end of the laying through roller. By means of the laying-pressing mechanism and a spray nozzle, the problem that the coiled material needs to be manually heated and then laid on the surface of a building, so that the working efficiency is low, and when the surface of the building is uneven, large gaps usually exist between the coiled material and the sinking parts or protruding parts of the building is solved.

[0001] The invention relates to the technical field of building construction, in particular to a small-sized coil automatic spreading vehicle and a coil spreading method. Background technique

[0002] At present, waterproof membranes have been widely used in various buildings due to their light weight and low price; however, during construction of waterproof membranes, it is required that the heated membranes be in good contact with the building surface. There is a large gap between them. When an object is pressed on the gap in the later stage, the air remaining in the gap will move to other places under the action of force, and the original well-bonded coil will be squeezed, or the coil will be broken. Thus affecting the waterproofing effect of the membrane and even causing waterproofing failure. In order to minimize the above-mentioned problems, three construction workers gradually release the coiled material during construction, one person holds the spray...
