ための防水シートの接合装置に関する。[Detailed description of the invention] Industrial application field This invention is a method for connecting soft and rigid resin waterproof sheets, which are laid on flat roofs of buildings, water tanks, etc., to each other at overlapping joints when they are laid. This invention relates to a waterproof sheet joining device.

れる。PRIOR TECHNOLOGY The construction of the above-mentioned waterproof sheets is carried out by stacking long unit waterproof sheets manufactured to a predetermined width and joining them together at their side edges, or by separately attaching them to each other. By stacking and joining band-shaped joining waterproof sheets made of the same material onto the butt joints of adjacent unit waterproof sheets, a continuous waterproof layer is formed over a wide area.

溶融して接合する熱融着による方法とが多く採用
されている。 There are two methods for joining such tarpaulin sheets: one is to weld the sheets together using a solvent-based adhesive, and the other is to use thermal fusion, which involves melting a portion of the tarpaulin sheet itself using heating means and joining the sheets together. It has been adopted.

が提案されている。 No matter which joining method is used,
When installing a waterproof sheet over a large area,
When such joining is performed manually, not only does it take a great deal of time and effort, but even with a high degree of skill, there are likely to be defective joints due to incomplete welding and fusion. For this reason, various bonding devices have recently been proposed for automatically or semi-automatically performing the bonding work.

があつた。Problems that the invention aims to solve However, in the case of these conventional proposals, the equipment is quite large and expensive, lacks lightness, and is unsuitable for constructing tarpaulins in relatively small areas. However, in the case of relatively light products such as the one shown in Japanese Utility Model Publication No. 47-38606, it is not only difficult to operate and work, but also does not necessarily provide a stable and reliable sealing condition. The problem was that it was difficult to guarantee the bonding of the two.

あつた。 Furthermore, in conventional devices that apply adhesives, especially solvent-based adhesives, to the joints of waterproof sheets, the running speed of the device that runs along the joint edges of the waterproof sheets is generally low. Or, the amount of adhesive applied does not correspond well to the progress speed, which tends to cause uneven application due to excessive application or insufficient application, which in turn tends to cause deterioration in the appearance of the finished state of the joint, poor joining, etc. There was a problem.

そして、このような問題点のために、従来提案

に至つていないのが実情である。 Due to these problems, the reality is that most of the conventionally proposed bonding devices have not yet been put into practical use.

することを目的とする。 In view of the above-mentioned problems, this invention is relatively easy to manufacture and can be provided at low cost.
In addition, it is a waterproof sheet using a solvent-based adhesive application method that is truly practical and satisfies the requirements of being able to achieve reliable joining of the waterproof sheet without causing uneven application of the adhesive. The purpose is to provide a joining device.

Therefore, the amount of adhesive discharged from the nozzle corresponds to the running speed of the trolley, and an appropriate amount of adhesive is always supplied between the joint edges of the waterproof sheet, ensuring uniform application. .
Subsequently, the joining edges are pressed down with a required pressure by a pressing roll, and as a result, reliable joining is achieved.

Most commonly, flexible polyvinyl chloride sheets with a thickness of about 1.0 to 2.0 mm are used, but other flexible synthetic resin sheets such as polyethylene and polypropylene, non-vulcanized rubber sheets, rubber asphalt sheets, etc. are also used. There is also. In addition, the adhesive used for these connections is selected depending on the material of the waterproof sheet, but in the case of a vinyl chloride waterproof sheet, for example, tetrahydrofuran, or a small amount of vinyl chloride resin dissolved in it, is used. It is preferred and common to use solvent-based adhesives such as those described above. Depending on the type of other tarpaulin sheets,
Various solvent-based adhesives, epoxy-based, urethane-based, rubber-based adhesives, etc. may also be used.

次に、上記実施例に示した接合装置による防水

遂行される。 As shown in FIG. 1, when the first and second waterproof sheets S1 and S2 are joined by overlapping their edges, the valve 25 belonging to one nozzle 8 installed on the truck 1 is in the closed position, and the other nozzle 8 is inserted to a predetermined depth between the edges of the waterproof sheets S1 and S2, and the cart 1 is placed on the waterproof sheets S1 and S2. And handle 2
0 and push the cart 1 along the joint edge at a desired speed. Then, the presser rolls 2, 3, 4, and 5 are rotated by contact with the waterproof sheets S1 and S2, and the rotation of the second roll 3 drives the metering pump 13 via the gear belt 19. be done. Therefore, the adhesive contained therein is transferred from the adhesive tank 22 to the transport tube 17, the branch pipe 24, and the branch transport tube 2.
6 to a nozzle 8, and is discharged from the nozzle 8 between the joint edges of both waterproof sheets S1 and S2. This discharge amount corresponds to the feed amount from the pump 13, and this feed amount corresponds to the traveling speed of the truck 1. For this reason, in response to the running speed of the truck 1, when it is slow, the discharge amount per unit time is reduced,
When the speed is high, an appropriate amount of adhesive is supplied evenly along the length of the joining edge. The adhesive spreads between the two bonding edges as they overlap once again through the passage of the nozzle 8, and then spreads between the bonding rollers 2, 3, 4, and 5.
By sequentially pressing down from above multiple times in stages, both joining edges are brought into close contact with each other in a securely sealed state. In this way, as the trolley 1 travels, the waterproof sheets S1 and S2 are continuously joined.

It may be configured as a Catapillar (registered trademark) type. In that case, one or more running wheels may be separately provided to ensure stable running performance of the trolley 1, if necessary. Therefore, it is better to drive the pump 13 by extracting the rotational driving force from the presser roll 3 (including the Caterpillar (registered trademark)) as in the illustrated embodiment, since it is more reliable by taking advantage of its non-slip property. Although this is preferable in that drive can be guaranteed, it is also possible to extract the driving force from the above-mentioned wheels and to connect them in conjunction with the wheels.

As described above, the amount of adhesive discharged or supplied from the nozzle can be made to automatically correspond to the traveling speed of the truck. Therefore, regardless of changes in the traveling speed or pushing speed of the truck, a predetermined amount of adhesive can always be uniformly supplied to the joining edges of the waterproof sheets from the initial stage of the joining operation, and uneven application can be prevented. Waterproof sheets can be easily and reliably joined without causing poor joining or deterioration of appearance due to
