Technical Field
[0001] This utility model relates to the technical field of waterproof membrane laying devices, specifically to a construction device for the overlapping area of waterproof membrane. Background Technology
[0002] When laying waterproof membrane over a large area, adjacent membranes need to be overlapped. The overlap area is a weak point in waterproofing, requiring strict quality control during construction to prevent leaks caused by improper treatment. Currently, mainstream waterproof membranes, such as elastomeric modified bitumen waterproof membranes, modified bitumen polyethylene waterproof membranes, and self-adhesive polymer-modified bitumen waterproof membranes, typically have an overlap width of 80-100mm. These types of membranes require a hot-melt method for installation. The general process involves using a flame heater to evenly heat the membrane before rolling it out, removing air bubbles, and then firmly adhering it. Finally, the overlaps and unsealed areas are sealed with excess hot-melt modified bitumen adhesive, completing the waterproof membrane installation.
[0003] The construction and treatment of this type of waterproof membrane overlap area generally follows the corresponding construction technology and process given in the specifications. Usually, 2-3 construction workers work together at the same time. The specific construction process is as follows: first, the side of the waterproof membrane to be overlapped is flipped up and heated with a flame torch. After the adhesion of the waterproof membrane at the overlap position meets the overlap requirements, it is evenly pressed onto the other side of the waterproof membrane and the air below is removed. Then, a construction worker uses a roller of appropriate width to roll it to improve the overlap effect and ensure that the waterproof membrane at the overlap position is tightly bonded. The above steps are repeated until all the waterproof membrane overlap construction is completed to form an overall waterproof structure. However, this construction method requires a large amount of manual labor for simultaneous operation, resulting in low construction efficiency and high labor occupancy. The construction method of using a flame torch for heating and pressing with limbs requires a high level of skill from the construction workers and is prone to burns. In addition, the construction workers have varying levels of experience, and when heating the roll material repeatedly and evenly, problems such as insufficient heating, overheating, and uneven heating are easily caused, which affect the construction quality and create the risk of leakage.
[0004] Therefore, how to solve the above-mentioned technical problems has become the subject of this utility model. Utility Model Content
