Embodiment
Below, by embodiment the present invention is further described.
Fig. 1 is the sectional view of the described waterproof construction of one embodiment of the present of invention.Among the figure, the 11st, as the waterproof roll of waterproof roll, this waterproof roll 11 as known in the art, the dip coated modified bitumen forms on base material, is formed with the mineral matter layer of sand 12 as polished surface from the teeth outwards.The 13rd, be located in the following layer coiled material between the surface of described waterproof roll 11 and base concrete S.Following layer coiled material 13 engages fixing with basal surface by the adhesive layer that is formed at soffit, on the other hand, the top layer part of following layer coiled material 13 and the waterproof roll 11 following layer coiled material 13 by being heated fusion is bonding.
Among Fig. 1, whole ground of following layer coiled material 13 and basal surface is bonding, but also can form known insulation division between the two described, forms the so-called exhaust channel that swells of being used to prevent.
Fig. 2 is the sectional view of an embodiment of following layer coiled material 13 shown in Figure 1.The main part of this time layer coiled material 13 is obtained by dip coated modified bitumen on base material 14, forms bitumen layer 15 and bitumen layer 16.The modified bitumen of bitumen layer 15 use with bitumen layer 16 compare the better material of meltbility.In addition in the drawings, the 17th, by the hot melt layer that heating is melted, hot melt layer 17 is made of the top layer part of bitumen layer 15 in the present embodiment.In addition, 17a pastes the 1st barrier material that is arranged on hot melt layer 17 (bitumen layer 15) surface.In addition, the 18th, be formed at the lip-deep adhesive layer of described bitumen layer 16, the surface is covered with the 2nd barrier material.
For the described layer coiled material down of present embodiment, further describe by Fig. 3.Fig. 3 is that the part of following layer coiled material 13 shown in Figure 2 is omitted stereogram.The 1st barrier material 17a that stickup is arranged on hot melt layer 17 (bitumen layer 15) surface is made of resin film 17b and the trellis body 17c as cushion coat that forms by the printing coating of using foam ink at its back side.
As resin film, can use polyethylene, polypropylene, nylon, polyester etc. any, but the high material of heat resisting temperature is unfavorable.From this angle, better be polyethylene, polypropylene, nylon, low-melting point polyester.In addition, about thickness, because make the relation of its thermal contraction, and the film that shrinks remains in the hot melt layer surface, so better be below the 50 μ m.In addition, as foam ink, use in solvent dissolution heat plastic synthetic resin, add the material known of blowing agent again.
Among this embodiment, the 1st barrier material 17a has above-mentioned structure, but also can 17 moments of hot melt layer directly be exposed, thereby this fusion rapidly, carry out easily by adopting the structure of as foamed styrene powder bed, polystyrene film easy fusion or contraction, making.
, the step of constructing of the waterproof construction that uses down layer coiled material 13 is described to Fig. 4 around Fig. 1.
Among Fig. 4,11 relate to the waterproof roll that Fig. 1 has stated, have mineral matter layer of sand 12 on the surface, are web-like to roll.In addition, the 13rd, stick to the following layer coiled material on cast concrete base S surface.Following the carrying out of following layer coiled material 13 based joints: the 2nd barrier material 18a of following layer coiled material 13 shown in Figure 2 is made of release film or release liners, it is peelled off push on the surface that anchors at substrate S after exposing adhesive layer 18.
Then, as shown in Figure 4, will be as after being waterproof roll 11 that web-like takes in and being placed on down assigned address on the layer coiled material 13 of waterproof roll, the flames F exiting of radiation blowtorch B, baking is the surface of layer coiled material 13 down, make hot melt layer 17 (constituting by bitumen layer 15 in the present embodiment) fusion of following layer coiled material 13 shown in Figure 3, on this fusion face, launch coiled material, waterproof roll 11 sets are engaged.The radiation of flames F exiting since the surface of the following layer coiled material of confirming with easy naked eyes 13 as object, the operator can easily confirm to adjust molten condition on one side, operate on one side, can be implemented in the bonding of waterproof roll 11 under the suitable condition and following layer coiled material 13, compared with prior art, can realize much better construction precision.
In Fig. 2 and Fig. 3, the flame radiation in the baking operation is carried out from the top of the 1st barrier material 17a.By heating, at first the foaming ingredient from the trellis body 17c that uses foam ink produces gas, forms the space between hot melt layer 17 and the film 17b.Because the gap is compared with foaming part not, thermal capacitance is very little, so the heat film 17b of this part by flame easily fuses certainly.Then, caused that by it the film 17b integral body of lining hot melt layer 17 disperses to shrink finely, hot melt layer 17 is by less heat exposure fusion.In the present embodiment, constitute heater means, but also can adopt the injection of hot blast with the radiation of the flame of blowtorch.
As mentioned above, if adopt the present invention, then can fuse the barrier material of the coating adhesive layer of liquid by for example citrene and so on or pastel rapidly, adhesive layer is exposed, be fixed on the basal surface with being about to lower floor's coiled material joint, in the process of constructing, the fusion of the barrier material in the following layer coiled material and the fusion of hot melt layer also can be seen clearly molten condition in operator's the suitable visual field, be construction precision so can obtain good efficiency of construction simultaneously.In addition,,, after construction just, also can keep the rigidity of regulation, avoid the problem of easy deformation and so on so the fire damage to waterproof roll can not take place because heating is carried out following layer coiled material.
Advantage when allowing the following layer coiled material that adopts the application is clearer and more definite, below in the past the following layer coiled material and the thermal bonding job practices of waterproof roll is described.
Fig. 5 is the sectional view of described waterproof roll, and this waterproof roll 2 has the structure of dip coated modified bitumen on base materials such as nonwoven 3.Among the figure, 2a is the high bitumen layer of melt temperature, is formed with the mineral matter layer of sand as the fine finishining layer on the surface.In addition, 2b is the modified asphalt layer of base side, corresponding to the heat construction method, uses the lower material of melt temperature, on the surface, promptly the face relative with substrate adhered to as the resin film 4 that is used to prevent bonding barrier layer etc.
In the construction of the bituminous waterproofing heat construction method at position, plane in the past, the asphalt blocks of regulation shape are pulverized, input is with in the pots as thermal source such as Wick lifter of kerosine burner, be heated to 260 ° of left and right sides fusions Celsius, be transported to the job location by 18 liters of containers etc., carry out scattering equably with spoonful pitch in the place ahead of roofing materials and engaging the operation of laying roofing materials thereon, repeat 2～3 times the formation asphalt tanking by this way fusion.
Yet, have following problem in the above-mentioned prior art.
(a) owing to move into melting pot at the construction field (site), the heating stipulated time is carried out operation with its spreading after fusing, and therefore has problems such as operating efficiency, cost; Also owing to will handle fusion and be in the pitch of high hot state, so these operations itself also will inevitably have danger inevitably.
(b) can throw into question to the environment around the job site.That is, follow the heating fusion operation of pitch to produce cigarette and foul smell, they can bring harmful effect to the dwelling environment of surrounding resident.This problem is especially remarkable in renovation project of inhabited building etc.
Fig. 6 is the key diagram that adopt to use the job practices in the past in the substrate waterproof construction of adhesion job practices of aforementioned waterproof roll.In this job practices, at first on basal surface S, be coated with primer as required, then the modification waterproof roll 2 that will be rolled into web-like on one side launches in the direction of arrows, on one side by toasting to the flames F exiting of the back side of modification waterproof roll 2 radiation blowtorch B, make modified bitumen 2 described modified asphalt layer 2a surface, comprise resin film 4 fusions.After the modified bitumen fusion, rotate modification waterproof roll 2 like this, fusion place by being pressed on the basal surface S, is repeated this operation then, modification waterproof roll 2 joints are fixed in the substrate.But there is following problem in such job practices.
(c) because use the heating of blowtorch be the operator hand-held it carry out, so can can't keep the radiation of flame in the right direction, therefore the heat emission meeting of the bitumen layer of target be produced unevenly, can't obtain correct molten condition sometimes.
(d) because the radiation direction of flame is the narrow that is surrounded by substrate and coiled material, therefore the operator is difficult for naked eyes affirmation fusion situation, residual sometimes not puddle for the precision that the bond degree of waterproof roll and substrate can't obtain stipulating, may damage the waterproof reliability.
(e) because the back side of heating waterproof roll itself makes its fusion, so can the fine finishining layer (mineral matter layer of sand) of face side be exerted an adverse impact, after perhaps just having adhered to construction, still be in the waterproof roll easy deformation of soft state, need at the construction field (site) to note carefully, also can influence efficiency of construction.
Relative therewith, because as long as the application's following layer coiled material and the set that engages waterproof roll thereon be layer coiled material surface under the heating and melting, so above-mentioned in the past the such problem of job practices is solved.
