Description

Technical Field

[0001] The utility model relates to the technical field of waterproof construction, in particular to a roof waterproof construction paving device. Background Art

[0002] Waterproof membrane is a flexible building material product that can be rolled into a roll and is commonly used for building roof waterproofing. Currently, many different types of waterproof membrane paving equipment have appeared on the market. Compared with the traditional manual heating paving operation method, the paving efficiency of this type of paving equipment has obvious advantages.

[0003] After searching, the patent with announcement number CN221422744U discloses a waterproof membrane paver. Through the coordination between the base plate, the limiting paving mechanism and the hot melt mechanism of the utility model, the waterproof membrane can be limited and guided when the paver is used to lay the waterproof membrane, avoiding the displacement and dislocation of the waterproof membrane during the laying process, which causes the need for re-paving, thereby improving the paving construction efficiency.

[0004] Another example is a waterproof roll material paving device disclosed in the patent with announcement number CN221031525U, which achieves the effect of facilitating the rapid paving of waterproof roll materials of different sizes through the coordinated use of a base, a storage square hole, a hydraulic push rod, a universal wheel, a clamping structure, an adjustment spring, an adjustment bracket and a roller; the coordinated use of a base, a protective cover and a glass window achieves the effect of minimizing the contamination of the waterproof roll material by external impurities; the coordinated use of a base, a load-bearing frame, a load-bearing plate, a servo motor, a rotating shaft and fan blades achieves the effect of accelerating the air flow speed around the roll material and improving the roll material paving efficiency.

[0005] Although the above schemes can all quickly spread the waterproof membrane, when installing the waterproof membrane, since the pressure rollers used by both to make the waterproof membrane stick tightly to the ground are pressed against the ground under the action of springs, it is not convenient to pass the end of the newly installed membrane through the pressure roller and the ground. In addition, when the waterproof membrane is rolled by only a single pressure roller, the air between the membrane and the ground is easily discharged from the edges on both sides of the membrane, resulting in the edges of the membrane not sticking firmly to the ground, which needs to be improved.
