Abstract

The invention relates to a building waterproof heat-preservation exhaust compound system, which comprises a heat-preservation layer, a waterproof layer, a waterproof protective layer and an exhaust passage, and is characterized in that the heat-preservation layer comprises paved heat-preservation boards, the lower surfaces of the heat-preservation boards are provided with exhaust grooves, the exhaust grooves of all the heat-preservation boards are connected into the exhaust passage, one end of the exhaust passage is connected into a flue through a connecting pipe, and the waterproof layer and the waterproof protective layer are covered on the heat-preservation layer in turn. The building waterproof heat-preservation exhaust compound system has the following advantages that: the system is a heat-preservation waterproof moisture-proof exhaust system for roofs and the floors, which uses a JWG-M type to seal and resist water for EPS and XPS heat-preservation boards, is communicated with the flue through the exhaust grooves of the EPS and XPS heat-preservation boards, and exhausts moist air in time by the pipeline effect of the flue so as to achieve waterproof heat-preservation exhaust integral roofs. Simultaneously, the system removes the vertical exhaust pipes arranged on the roofs and reduces the hidden danger of seepage, and the roofs are smooth to prevent frost heave and gas heave so that the deserved effective service life of the waterproof and heat-preservation roofs is achieved. Besides, the system has good heat-preservation and waterproof effects.

Description

Building waterproof heat-preservation exhaust compound system and job practices

Technical field

The invention belongs to a kind of building waterproof heat-preservation technology.

Background technology

At present, the waterproof on roof, adopt of insulation are provided with insulation layer more on the roof cement pre-fabricated panel, cover waterproofing course then on insulation layer.The insulation layer of deck adopts more lays insulation plate or cast-in-place cement expanded perlite.Wherein, laying insulation plate makes and leaves more water space in the deck insulation layer, and the interface dewfall phenomenon of heat insulating material and other materials (as leveling layer) is difficult to avoid simultaneously.For the insulation layer of cast-in-place cement expanded perlite, cast-in-place thing (as expanded perlite) water absorption rate is excessive.Sloping layer and insulation layer moisture content and injection water retaining in reservoir are excessive, cause winter " frost heave " tympanites in summer (bulge), bring out waterproofing course and destroy and insulation failure.Cause heat-insulating property decay too fast and go out of use.

Roof waterproof, heat insulation function cause short term failure because of the frost heave tympanites; Ground floor is subjected to the puzzlement of humidity, cool place, stale musty throughout the year; Also have, as the cave depot in military reserve supply storehouse, mostly build in the mountain, be subjected to seepage, sombre, moist, mouldy puzzlement for a long time, preserve to material and bring very burden, particularly leakage problems, the influence that causes is destructive.

(2) solution

Cave depot (military articles for use such as ammunition depot warehouse) is subjected to the infringement of percolating water, humidity for a long time.These are unusual general phenomenon at present, have caused the waste of the energy and goods and materials very serious, are the difficult problems in these fields of puzzlement.For many years, never solved completely.

Summary of the invention

The purpose of this invention is to provide a kind of building waterproof heat-preservation exhaust compound system and job practices, the problem of the fine solution building waterproof heat-preservation of energy, insulation, waterproof, good exhaust effect.

Waterproof heat-preservation exhaust compound system provided by the invention: it comprises insulation layer, waterproofing course, fish tail and waterproof layer, exhaust passage; it is characterized in that: the warming plate of insulation layer for laying; offer air discharge duct on the soffit of warming plate; the air discharge duct of each warming plate connects into the exhaust passage; one end of exhaust passage is coupled in the flue by tube connector, covers waterproofing course and fish tail and waterproof layer on insulation layer successively.

Roofing and ground insulating waterproof, protection against the tide, exhaust system, utilize the JWG-M type to the EPS warming plate seal, waterproof, air discharge duct by EPS, XPS warming plate is communicated with the flue of building, realize the timely discharge of wet gas by the pipe effect of flue, realize the integrated roofing of waterproof heat-preservation exhaust to the greatest extent.Cancelled the vertical exhaust pipes that roofing is provided with simultaneously, reduced the hidden danger of seepage, it is smooth that roofing becomes, and avoided frost heave, tympanites to take place, and makes roof waterproof and the due useful life of insulation be achieved.

Building waterproof heat-preservation hybrid system job practices provided by the invention:

1. EPS, XPS warming plate are tailored into the unit square, at the one side of the unit square air drain that begins to rehearse.

2. smear the cement mortar screeding layer on floor, after the maintenance, lay EPS, XPS warming plate, air discharge duct is downward, spreads to the flue place to be coupled in the flue with plastic pipe.

3. adopt the agent of JWG-M type water-tight to paste the nonwoven sealing in EPS, XPS warming plate plate seam.

4. do waterproofing course with the agent of JWG-M type water-tight, nonwoven, cement, fine sand integral body on EPS, XPS warming plate, sequence of construction is: paste nonwoven with JWG-M type water-tight agent and cement earlier, after doing solid work, press 1: 1: 2 the volume ratio and the water of convention amount with JWG-M type water-tight agent and cement, fine sand again, stir to be coated with and scrape, thickness 1-2mm.

5. after doing solid work, smear 20-30mm cement mortar protective course (doing 6m * 6m lattice) and carry out flashing, after maintenance is finished, can spray JWG-1 type waterproof agent and do one rigid waterproofing.Fill the lattice seam with conventional seals glue.

Advantage of the present invention is: roofing and ground insulating waterproof, protection against the tide, exhaust system, utilize the JWG-M type to EPS, XPS warming plate seal, waterproof, air discharge duct by EPS, XPS warming plate is communicated with the flue of building, realize the timely discharge of wet gas by the pipe effect of flue, realize the integrated roofing of waterproof heat-preservation exhaust to the greatest extent.Cancelled the vertical exhaust pipes that roofing is provided with simultaneously, reduced the hidden danger of seepage, it is smooth that roofing becomes, and avoided frost heave, tympanites to take place, and makes roof waterproof and the due useful life of insulation be achieved.Insulation, good water-proof effect.

Description of drawings

Fig. 1 is a waterproof heat-preservation exhaust compound system schematic diagram of the present invention.

The specific embodiment

See Fig. 1; building waterproof heat-preservation exhaust compound system provided by the invention comprises insulation layer, waterproofing course 1 and fish tail and waterproof layer 6; insulation layer is the warming plate 2 that is laid on the floor 5; warming plate 2 adopts EPS, XPS warming plate; on the soffit of warming plate 2, offer groined type air discharge duct 3; the air discharge duct 3 of each warming plate 2 of laying connects into the exhaust passage, and an end of exhaust passage is coupled in the flue 7 by plastic union pipe 8, covers waterproofing course 1 and fish tail and waterproof layer 6 on insulation layer 2 successively.Waterproofing course 1 adopts JWG-M type water-tight layer, and fish tail and waterproof layer 6 adopts JWG-1 type cement mortar fish tail and waterproof layer.

The job practices of the waterproof thermal-insulated hybrid system of deck provided by the invention:

1. determine the thickness δ mm of EPS, XPS warming plate by the requirement of locality, plate is tailored into 600mm * 600 (1000,1200) mm * δ mm, and fluting.

2. floor 5 is cleaned out, and smears the thick cement mortar screeding layer 4 of 10-20mm, after the maintenance, lays EPS, XPS warming plate, and air discharge duct 3 is downward, spreads to the flue place to be coupled in the flue 7 with plastic pipe 8.

3. paste nonwoven sealing EPS plate seam with the agent of JWG-M type water-tight.
