Abstract
The invention discloses a vent-thru-roof (VTR) assembly on a roof and a method for preventing a vent stack from a water leakage, belonging to the field of building. The assembly is composed of a roof vent pipe seat, a sealing rubber ring, a waterproof cap, a sealing rubber mat, a roof vent pipe, a ventilation cap, a plurality of fastening bolts and a plurality of fixing bolts. In the invention, a waterproof cap is installed above on a roof vent pipe seat, so that a roof water leakage caused by the stripping of a waterproof material, water leakage points formed by radial gaps appearing on a concrete roof plate, a waterproof sleeve, a vent stack and a waterproof filling material caused by a temperature difference, and a gap water leakage formed by the mutual separation of the vent stack and the waterproof filling material caused by a shaking force and a thermal expansion can be efficiently prevented; and the VTR assembly on a roof is convenient to install.
Description
Technical field
The present invention relates to building field, particularly a kind of roofing stack vent assembly and prevent the method that vent stack leaks.
Background technology
Along with the fast development of China's construction market in the last few years, people are increasingly high to the quality requirement of building design and construction.The roofing stack vent is to be used for the ventilation of architectural drainage system and the device that scavenges, and according to existing Code for design of building water supply and sewerage, architectural drainage system must be provided with the ventilating pipe that passes through the roof roofing.The design and construction method mainly is to adopt earlier the steel water string to be poured into concrete mortar in advance to be fixed in the roofing floor layer at present; Vent stack passes the steel water string and sticks up on the roof; Fill the gap between steel water string and the vent stack with expansive cement mortar and water tight packing then, to prevent the rain water on roof seepage.
In realizing process of the present invention, the inventor finds that mainly there is following problem in the job practices of above-mentioned employing steel water string filling water tight packing:
Adopt water string when carrying out the roof waterproof layer construction; Waterproofing materials and water string joint portion are wrapped in the outside waterproofing materials of water string and are easy to from peeling off owing to roof high temperature is exposed to the sun; Make bleed along the slit of peeling off roof waterproof layer below of rainwater; And under the effect of superheated vapor evaporation, waterproofing course produces bulge to be separated with roof panel, forms roof leakage.
Adopt the vent stack of water string passing through floors construction; Season, the temperature difference was big round the clock owing to roofing, and the coefficient of expansion of concrete roof plate, water string, vent stack and water tight packing is different, through after a while; These materials are easy to generate radial clearance each other, form leakage point.
Multilayer and highrise building drainage ventilation standpipe adopt flexible iron drain-pipes or plastic pipes more at present; Owing to be out of shape by shaking force and thermal expansion; Tubing tends to produce bigger displacement vertically, causes vent stack and waterproof packing material to break away from each other, forms the gap and leaks.
Summary of the invention
Peel off leakage point that the roof leakage, the temperature difference that cause cause that concrete roof plate, water string, vent stack and water tight packing radial clearance occurs and form, form problems such as the gap leaks owing to receiving shaking force and thermal expansion to cause that vent stack and waterproof packing material break away from each other in order to solve that existing ventilating pipe exists because water string outside waterproofing materials, the embodiment of the invention provides a kind of roofing stack vent assembly and has prevented the method that vent stack leaks.Said technical scheme is following:
A kind of roofing stack vent assembly, said assembly is made up of ceiling duct seat, O-ring seal, tarpaulin, seal gasket, ceiling duct, ventilative cap, a plurality of fastening bolt and a plurality of set bolt;
Wherein, Said ceiling duct seat is tubaeform; Be fixed on the top of the roof floor slab layer of the pore that is reserved with vent stack; Said ceiling duct seat is inserted with said vent stack through the bell and spigot of below; The internal diameter of the bell and spigot of said ceiling duct seat is greater than the external diameter of said vent stack, and said O-ring seal is fixed in the bell and spigot groove of said ceiling duct seat below, and the outer wall of the groove inwall of said ceiling duct seat and said vent stack is airtight through said O-ring seal;
Said seal gasket and said tarpaulin are fixed on the top of said ceiling duct seat through said a plurality of fastening bolts; The diameter of said seal gasket is identical with the diameter of the last interface of said ceiling duct seat; So that said tarpaulin and said ceiling duct seat fluid-tight engagement; The outer wall of said tarpaulin covers on the top of said ceiling duct seat; In case rainwater infiltrates from the waterproof roll that surrounds said ceiling duct seat outer wall and the bonding gap not firm or cracking of said ceiling duct seat outer wall, and protect said waterproof roll not by sunlight exposure and season cracking.
Said ceiling duct is installed in the bell and spigot of said tarpaulin top, and fixes through said set bolt;
Said ventilative cap is a hemispherical, and is fixed in said ceiling duct top through said set bolt, pours into said ceiling duct to prevent rainwater.
Further, said ceiling duct seat is fixed on the top of the roof floor slab layer of the pore that is reserved with said vent stack through expansion nut.
Further, the length of said ceiling duct is confirmed the requirement of ventilative cap height according to architectural design.
Further, the pipe end of said vent stack top remains with predetermined gap with the bell and spigot of said ceiling duct seat below, but so that said vent stack easy on and off is flexible.
Further, the top of said ceiling duct seat has a plurality of stupefied rings, so that tie up fixedly waterproof roll, prevents that said waterproof roll from leaking and come off.
Based on above-mentioned roofing stack vent assembly, a kind of method that prevents that vent stack from leaking, said method comprises:
Steps A, the ceiling duct seat is fixed on the top of the roofing floor layer of the pore that is reserved with vent stack with expansion nut;
Step B, waterproof roll parcel is pasted to the stupefied ring portion position of said ceiling duct seat;
