Description

Waterproof construction tablet
Technical field
The present invention relates to the position be particularly exposed in rainfall or flowing water at building, the waterproof construction tablet used when carrying out waterproof construction.
Background technology
As the water-proof construction method of the floor etc. on the roof or roof parking area of bestowing building structure, there will be a known after the body face of building structure carried out silane coupling agent process by (1), configuration reinforcement cloth, after forming the waterproof sheet material layers of carbamate system etc., the closely sealed engineering method be coated to is carried out thereon with surface coating, (2) the ventilation sheet of bonding non-woven fabrics etc. on whole of basalis, the coating asv buffer engineering method etc. forming waterproof sheet material layers thereon.
But the former closely sealed engineering method, due to waterproof sheet material layers is engaged integration in the universe of substrate surface, the tracing ability for the movement of the crackle occurred in substrate or seam is insufficient.And, moisture Yin Wendu contained in basalis rises and becomes steam, when diffusing to the interface portion of basalis and waterproof sheet material layers, due to steam loss nowhere, thus have and occur to cause because of this water vapor pressure waterproof sheet material layers to peel off and the shortcoming of phenomenon (being commonly referred to as " swelling ") heaved from base part.
In contrast, by the asv buffer engineering method of the latter, aeration fender plays degassing performance, owing to being directed to degassing tower by cushioning sheet material layers from basalis steam out by the aeration of joint interface and being released to outside, thus prevents swelling described above.But, if compared with closely sealed engineering method, be then noted owing to constructing numerous and diverse and need the problem in the construction of time etc.
Be used for improving in the patent document 1 of the problems referred to above, proposing and be coated with sealant on whole of the body of building structure, across bonding sheet on sealing agent coated face, after bonding sheet is bonded isolator, the engineering method of coating paint for water-proof.
By this engineering method, bonding sheet portions educe degassing performance thus repression of swelling phenomenon, the tracing ability simultaneously for the movement of the crackle occurred in substrate or seam also improves.But at construction site, owing to needing the huge artificial and time in the paste operation of this bonding sheet, application property significantly reduces.Be conceived to this problem, developed and can prevent the swelling waterproof construction technology that application property is also excellent simultaneously, proposed patent document 2.
But, during construction, comprise following problem and there is room for improvement: low viscous silane coupling agent easily invades in long fibre nonwoven layer of cloth, and Inter-fiber voids is full of by silane coupling agent and becomes aeration deficiency, the steam come from basalis diffusion becomes and is difficult to be distributed to outside.
In addition, as other technology, propose and the related development technique of patent document 3.This technology proposes at least one side of the tablet with aeration, by giving resin with the state be communicated with substantially, forms irregular application type waterproof fortification tablet.Irregular of the tool of this tablet is laid with the state connected with substrate, be coated with silane coupling agent and bonding tablet and substrate from the upper side, then coating waterproofing material is coated with further thereon, above-mentioned concavo-convex as being communicated to outside voids left by making, thus the steam come from basalis diffusion externally can be distributed.
This tablet, as as shown in the 1st figure of patent document 3, in the part of aeration tablet I, basalis engages integrated with the waterproof sheet material layers that it is formed, in clathrate or the honey comb like part presenting the resin II that wire is communicated with, by with basalis and the asynthetic mode of waterproof sheet material layers, form gap in the part of this resin II and make it have aeration, because the steam etc. of releasing from basalis externally distributes via this gap, extraordinary expansion preventing effectiveness can be obtained.
But in this tablet, limit overleaf side forms the trivial operations of the resin II of concavo-convex limit application formation through being communicated with and takes artificial, except the application operability containing this application operation has except problem, this tablet is arranged after substrate surface, to be coated with silane coupling agent time, because common silane coupling agent is low viscosity, silane coupling agent invades the rear side of the resin II part be communicated with and is full of in gap, result has situation about losing as the function of steam vent, also has the situation that can not get desired expansion preventing effectiveness.Therefore, for this tablet and the water-proof construction method using it, also there is room for improvement.
One of the present inventor also proposes the technology of tablet as other of announcement in patent document 4.This technology proposes: on the one side of non-poisture-penetrability metallic film or non-poisture-penetrability metal deposition film, engaging non-woven fabrics by layered manner etc., by making to have with the joint interface of waterproof sheet material layers anchoring effect, thus improving the method for cementability.Consider the cost or light weight etc. of above-mentioned non-poisture-penetrability metallic film or non-poisture-penetrability metal deposition film due to this tablet and generally use thin material, when therefore operating at the scene, roll from paved surface because of wind or fold, operability can difficulty a little, but can improve rigidity as tablet entirety via fit this sheet and fabric of adhesive.
But, the fusible demand of further raising tablet is strong, as improving technology of future generation, develop and used flat gauze (flatyarn) to form fabric in netted reinforcing material, superimposed non-poisture-penetrability metallic film or non-poisture-penetrability metal deposition film, carried out the tablet of easy bond processing to one side.It is when engaging with basalis, engage along the arbitrary concavo-convex superfine of substrate surface, although its engaging force brings remarkable effect, but in time constructing, because tablet operates under the state being wound into cloth web-like, during from cloth volume pull-out sheet, the so-called adhesion (blocking) be close to due to cohesive rolled up by cloth, uncoiling cannot smoothly be carried out, and has a so-called difficult problem such as the generation distortion of sheet or the stripping of metal film etc.In this case, strongly need waterproof construction tablet to possess sufficient cohesive, do not stick together simultaneously when uncoiling, without the stripping of metal film, the uncoiling of sheet cloth volume is for being easy to tablet.

Detailed description of the invention
Below, the formation of waterproof construction tablet of the present invention is described in detail.Waterproof construction tablet 1 of the present invention, as above-mentioned, is the tablet that the non-poisture-penetrability metallic film 2 being formed with multiple hole 5 (opening portion) is stacked via adhesive layer with netted reinforced textile 6.Tablet is rolled into the state of roller, rolls out from roller when the laying of sheet, by the extension on the substrate surface needing waterproof construction of non-poisture-penetrability metallic film aspect.Now, owing to giving adhesive to the netted reinforced textile of opening portion, basal surface is adhered to by this bonding effect.By from the upper side coating comprise carbamate system resin etc. waterproof material and carry out waterproof construction.Under this waterproof construction state, perforate tablet of the present invention, at the part place in hole, comprises the basalis of concrete etc. and the coating waterproof sheet material layers on it and engages and integrally change into column.In contrast, in non-perforate part, because basalis and waterproof sheet material layers are by the existence of non-poisture-penetrability metallic film, thus stop and directly engage, do not occur to engage integration between them, this part is formed and can be described as only with the state of the state contacts of void subsides.
And, in tablet of the present invention, multiple hole 5 is formed due to such as above-mentioned, therefore forming porose part, basalis engages integrated with waterproof sheet material layers, in the part of atresia, under substrate surface and non-poisture-penetrability metallic film 2 or non-poisture-penetrability metal deposition film are in disengaged condition, residual part becomes empty state of pasting, because the part of this empty subsides state is communicated with to the direction, circumference at two interfaces, therefore the gas componant spreading the steam come etc. in basalis flatly moves from mating face, and discharges to air from degassed cylinder.Therefore, be trapped in joint interface without the gas componant of this steam etc. and make waterproof sheet material layers expand phenomenon may.
Size or the number of above described holes 5 have no particular limits, if but each Kong Wei great and aperture area rate is wide, then due to the increase of the area ratio at one junction surface, the bond strength of basalis and waterproof sheet material layers improves, but on the other hand, the void of exhaust is pasted region area and is narrowed, expansion preventing effectiveness reduces, on the contrary, if hole is little and aperture area rate is narrow, then exhaust effect improves, but then, the area ratio at one junction surface reduces, and the bond strength of basalis and waterproof sheet material layers becomes not enough a little.Therefore, in order to both guarantee sufficient bond strength between basalis-waterproof sheet material layers, the gas componant of the steam diffusing to boundary interface etc. is made again externally to spread efficiently from degassing tower and guarantee to prevent swelling, the aperture area rate of the above described holes being formed at tablet is preferably made to be more than 5%, be preferably less than more than 10% 70%, be more preferably less than more than 20% 60%.
In addition, during due to each hole 5 undersized, be difficult to obtain gratifying one engaging force, on the contrary, time excessive, the area of exhaust narrows and has the possibility that expansion preventing effectiveness becomes insufficient, and the diameter that the size in each hole converts in positive round is preferably below more than 3mm about 100mm, is particularly preferably below more than 5mm about 20mm.
The shape in hole 5 has no particular limits, and can become the polygon-shaped of round type, ellipticity, oval shape, square shape, pentagon or hexagon etc. or arbitrary different form, according to circumstances also can by difform hole to combine multiple formation arbitrarily.But, in order to during operation as tablet or construction time be difficult to be subject to cause because of applied tension force etc. tear damaged etc., preferably become the few toroidal of notch effect or elliptical shape.
In addition, waterproof construction tablet 1 of the present invention, because the part contacted with waterproof sheet material layers is web state, therefore the film of waterproof sheet material layers gos deep in fabric that bond strength uprises well.
At above-mentioned non-poisture-penetrability metallic film 2 used in the present invention, not special restriction, such as, can use the metallic film of aluminium or copper, stainless steel etc.In addition, non-poisture-penetrability metal deposition film also has no particular limits, such as can be used on the film of various independent or copolymer resins or blending resin etc. of the polyolefin, polyester, polyamide etc. of polyethylene or polypropylene etc., evaporation has the metal deposition film etc. of aluminium, copper etc.As long as be the material that can stop the intrusion in waterproof sheet material layers constituent basad layer direction and empty subsides state can be ensured, then can use arbitrary metallic film or metal deposition film.The thickness of this metallic film or metal deposition film also has no particular limits, and synthetically considers operability or cost etc., is preferably about 3 ~ 200 μm, is more preferably about 8 ~ 38 μm.
In addition, in waterproof construction tablet 1 of the present invention, in order to improve the degassing performance with the engaging force of waterproof sheet material layers 10 or steam etc. further, when using the non-poisture-penetrability metal deposition film of this tablet of formation, the method making its aggregate formed containing silica sand etc. in material is also effective.This is because in this membranogen material during fusion aggregate, then give fine concavo-convex to film by this aggregate, the space between basalis and this thin layer broadens, and not only degassing performance improves, and this concavo-convex also contributing to improves with the cohesive of waterproof sheet material layers.In above-mentioned waterproof construction tablet 1 of the present invention, above-mentioned thin-film material face is laminated with netted reinforced textile 6 via adhesive.Namely, this netted reinforced textile 6 improves the intensity as tablet entirety, particularly hot strength or tearing strength, prevent the breakage because tensile stress during waterproof construction or suspension etc. cause, also play the effect of the joint integraty improving the waterproof sheet material layers 10 be coated with the top side of this tablet further simultaneously.Especially, in the present invention, the chip architecture be made up of fiber relatively up to now, the structure of this netted reinforced textile 6 has in the characteristic point of netted reinforced textile 6 for being made up of depression forming part and protuberance forming section.The flat gauze 3 comprising thermoplastic synthetic resin is carried out the system of knitting and forms by recess.
Recess described in the present invention, just refer to only by flat gauze knit the part of system and be the thin part of the thickness of fabric.On the other hand, the protuberance of the fabric described in the present invention, refers to the part formed with the low count yarn that the flat gauze of apparent Thickness Ratio above-mentioned formation recess is large.
As the thermoplastic synthetic resin forming flat gauze, such as, can enumerate the polyolefin-based resins of polyester based resin, polypropylene etc., polyamide series resin, polyvinyl alcohol resin, acrylic resin or comprise these copolymer resins or the various chemicals of admixture.
Flat gauze 3 preferably comprises polyolefin.
Flat gauze described in the present invention, makes above-mentioned thermoplastic synthetic resin heating and melting in barrel exactly, by T die head method or inflation method from die head extruded film, this film is cut into after the cooling period the flat spun yarn that width is little.As required, also stretch process or thermal finalization can be implemented.
Flat gauze 3 combines with low count yarn 4, is made into the tissue of plain weave, twill weave by well-known loom.Fabric tissue does not limit, but is particularly preferably the netted reinforced textile being made plain weave, basket weave.
Low count yarn 4 can be used for warp thread and/or weft yarn.
The low count yarn thicker than the thickness of flat gauze 3 is knitted and is made and form by the protuberance of netted reinforced textile 6.The protuberance of netted reinforced textile 6 by inweaving more than 1.2 times that thickness is the thickness of the flat gauze 3 forming recess, preferably more than 1.3 times low count yarn 4 and formed.
Low count yarn described in the present invention, as long as the yarn that the flat gauze of apparent Thickness Ratio formation recess is large, then there is no particular limitation, such as, can be synthetic fibers multifilament, synthetic fibers monofilament, the spinning employing synthetic fibers short fiber, the spinning comprising natural fiber, composite spinning, processing yarn etc. any one.As long as the yarn that the depression forming part of the Thickness Ratio fabric formed is large, then can be any one, certainly also can be the flat gauze that thickness is large.
The diameter of low count yarn 4 is preferably the scope of 100 ~ 1000 μm.The thickness of low count yarn 4 is preferably 1.2 ~ 10 times of the thickness of flat gauze 3.
Flat gauze 3 preferably knits system with the density of knitting of 4 ~ 15 pieces/inch, and low count yarn 4 is preferably knitted be formed on warp thread and/or weft yarn with the density of knitting of 0.2 ~ 2.5 piece/inch.
In the past, tablet coils into the mode of cloth volume, when operating from cloth volume pull-out sheet when constructing operation, there is generation metal film to peel off, or cloth is rolled up the so-called adhesion closely sealed because of the cohesive of adhesive, is difficult to the problem of pull-out, but owing to being made up of depression forming part and protuberance forming section by above-mentioned netted reinforced textile 6, thus sheet contact area each other can be reduced, so the generation not having adhesion or peel off, during constructing operation, become very easy from the operation of cloth volume pull-out sheet.
During the uncoiling of waterproof construction tablet, load is preferably below 0.5N/cm, is particularly preferably below 0.3N/cm.
