CN2245088Y - Water-proof coiled material with air exit hole - Google Patents

Abstract

The utility model discloses a water-proof coiled material with an air exit hole. The utility model is characterized in that small holes or small holes with loose-leaf connecting sheets are evenly distributed and manufactured on a common coiled material, and the opening and closing directions of the loose-leaf connecting sheets are consistent; when a roof is under construction, the utility model which is arranged on rolling adhesive can exclude air between the water-proof coiled material and the roof, avoid an empty drum and prevent the tension crack of the proof coiled material caused by the heat expansion and the cold contraction of residual air.

Description

A kind of waterproof roll with steam vent

The utility model is used for building waterproof or damp proof insulation.

The waterproof of existing building roof, normally adopt: be coated with one deck water-proof adhesive at roofing earlier, the laminated material that waterproof ability then will be arranged, be commonly called as waterproof roll, for example the pitch prill malthoid is sprawled one deck, simultaneously evenly roll extrusion thereon, so that it can be sturdy with roofing, and then be coated with alite paste, and waterproof roll is shut therein, reach the purpose of exclusion of water.In the above-mentioned construction,, and has certain degree of hardness because the common waterproof roll area that adopts is bigger, therefore when on cementing agent, sprawling, form many sticking up naturally and meet, though through roll extrusion, also be difficult to globality ground and the good appropriateness of roofing, behind the coating adhesive, air just is enclosed in below the coiled material again, form some hollowings, and the air in the hollowing, under the influence of the temperature difference, rising-heat contracting-cold, cause coiled material to take place gradually to open and split, directly destroy waterproof effect.

The purpose of this utility model will solve above-mentioned air residue problem exactly.

The utility model can be realized by following technical proposals: increase hole or loose-leaf type hole on existing common waterproof roll.The shape of aperture does not limit, and aperture and pitch-row are decided because of the coiled material thickness, all evenly distributes.When the loose-leaf type aperture is punching small holes, stays and a bit ofly do not cut off, the hole sheet that is dashed is connected on the coiled material, can folding as the door and window loose-leaf.Aperture with the loose-leaf aperture do not mix built in, make two kinds of products respectively.Coiled material with holes (comprising loose-leaf type) is when construction, and coiled material combines with roofing by cementing agent, through after the roll extrusion, is crushed on following air and just discharges by aperture, and it is tight to be beneficial to bonding.The folding direction of the link piece on the loose-leaf type aperture coiled material is convenient to roll extrusion and is from first to last once finished preferably along the length direction of coiled material, and in roll extrusion, finishes exhaust and coiled material and recover shaping.

Adopt waterproof roll of the present utility model, the opening of roof waterproof layer that can avoid causing owing to the residual air rising-heat contracting-cold split, and prolongs the life-span of roof waterproof layer.

Fig. 1 is the waterproof roll of unthreaded hole for the utility model.

Fig. 2 is a loose-leaf type aperture waterproof roll for the utility model.

Make common malthoid earlier, then with punch die towards it, rolling.

Be the cementing agent construction of having a talk below with the pitch prill.On the roofing that cleans up, be coated with earlier the pitch prill of enduring of one deck, repave waterproof roll with holes, along its roll extrusion forward, air is discharged, make the coiled material bonding simultaneously, be coated with the second road pitch prill again, waterproof roll is sealed with cylinder.The forms such as ', ' two three oil ' that adopts above-mentioned technology can be paved into ' one cloth two oil.

Claims (2)

1, a kind of waterproof roll is a body with existing common waterproof roll, it is characterized in that, makes perforation on existing common waterproof roll body, and perforation is evenly distributed.

2, waterproof roll according to claim 1 is characterized in that: perforation has loose-leaf brace, the folding direction unanimity of these braces.
