Description

Technical Field

[0001] The utility model belongs to the technical field of civil engineering construction, and particularly relates to a waterproof coiled material paving device. Background Art

[0002] The traditional paving device is to place a gas tank in the corner and connect it to a hand-held flamethrower through a long gas pipeline.

[0003] This paving device has the following defects: the required gas pipeline is long and has to cross the construction site, which greatly interferes with civilized construction; since the flamethrower is handheld, the distance between the muzzle and the coil is difficult to control evenly, resulting in uneven heating of the coil, and finally inconsistent bonding force and stress release; the handheld spray gun has no fire baffle, and the entire width of the coil is in a heated state. After the entire roll is heated, the paste adhesive can only be squeezed out separately to seal it. In this way, since the entire coil is already bonded, the bonding effect of squeezing the paste alone is greatly reduced. Utility Model Content

[0004] The utility model aims to provide a waterproof coiled material spreading device, which aims to solve the technical problems that the conventional hand-held flame spray gun causes uneven heating of the coiled materials and greatly reduces the bonding effect of the individual paste extrusion at the overlapping parts of adjacent coiled materials.

[0005] To achieve the above purpose, the utility model adopts the following technical solutions.

[0011] Preferably, the spacing between adjacent flame spray guns is 100 mm to 150 mm, and the spacing between the fire baffle and the left end of the mounting rod is 30 mm to 40 mm.

[0012] Compared with the prior art, the utility model has the following characteristics and beneficial effects.

[0013] 1. The gas pipeline in the waterproofing coiled material paving device of the utility model is very short, which is convenient for construction at the construction site, and the flamethrowers are fixed on the mounting rods, and their positions remain unchanged during the construction process. The coiled material can be heated evenly by rolling the coiled material at a uniform speed, thereby making the coiled material more bonded. At the same time, the utility model is provided with a group of spray gun nozzles, which has fast heating speed, high construction efficiency and less labor.

[0014] 2. The utility model is provided with a fire baffle at the left end of the mounting rod. The coiled material range on the left side of the fire baffle is in a non-heated state. When overlapping with the next coiled material, there is no need to squeeze a paste adhesive separately to bond, which greatly reduces the effect. The utility model reserves a part without heating. When overlapping with the next coiled material, the coiled material on the left side of the fire baffle can be directly heated and the paste adhesive can be squeezed out at the same time, thereby ensuring the sealing and construction quality of the overlapping part.
