Description

A kind of thermal isolation by water storage roofing

Technical field

The utility model relates to technical field of buildings, in particular to a kind of thermal isolation by water storage roofing.

Background technique

Social energy conservation building has become the wind vane of building field development now, and the energy saving of building also receives more Carry out the concern of more people.Reinforcing thermal performance of building envelope is the important link in building energy conservation, for example northern area is built The thermal insulation property of object and the heat-proof quality of southern area building are built, is all the important indicator of building energy conservation.

Water-ponding roof absorbs solar radiation and heat as a kind of novel heat-insulating technology, using the ponding on roofing Amount reduces roofing by thermal energy caused by sun direct irradiation, to play heat-insulated effect.Therefore the utility model proposes A kind of thermal isolation by water storage roofing.

Utility model content

The purpose of this utility model is to propose a kind of thermal isolation by water storage roofing, is asked to solve the insulation etc. of traditional roof Topic.

This thermal isolation by water storage roofing main composition has: roofing, waterproof layer, waterproof protective layer, insulating layer, heat insulation protecting layer, Drainpipe, water barrier, water storage ditch.

The waterproof layer has good heat-resisting quantity and winter resistance using SBS modified asphalt waterproof coiled material, can be with It is used within the scope of -25 DEG C~100 DEG C, while elasticity, fatigue durability and paracentesis resistance with higher；

The insulating layer in addition to excellent heat insulation property, also possesses good hydrophobic using XPS extruded sheet Moisture resistance and anti-corrosive properties, while also belonging to environment-friendly building materials；

The drainpipe is divided to main drainpipe and time two kinds of drainpipe, is embedded into heat insulation protecting layer using traditional pvc pipe Interior, in water storage ditch interval, water enters time drainpipe via drainage hole, then is discharged into main draining by secondary drainpipe for discharge outlet setting Pipe, finally enters building downpipe；

The water barrier is applied to water collecting sump circumferential surface using polyurethane water-proof paint, forms one layer of tough and tensile nothing Seam integral waterproofing film.

Compared with existing water-ponding roof structure, the utility model is had the advantage that

1, using the water filling of water storage ditch, the spatial area for taking full advantage of roof carries out water storage, and structure is simple, construction It is convenient；

2, using hydrophobicity thermal insulation material, insulating layer is avoided by upper layer water storage moisture effect, reduces the heat insulating ability of itself Energy；

3, possess the draining system optimized, from the drainage hole being arranged between water storage ditch, to time drainpipe, main draining Pipe, then architectural drainage system is arrived, without any confusion, hydrophobic effect is good for whole process；

Detailed description of the invention

Fig. 1 is the structural schematic diagram of the utility model；Fig. 2 is the utility model water barrier, water storage ditch, drainage hole, secondary row Water pipe, main drainpipe and the building specific attachment structure schematic diagram of downpipe.

The reference numerals are as follows:

Specific embodiment

Illustrate the technical solution of the utility model in order to clearer, the utility model is done further with reference to the accompanying drawing Detailed description.

A kind of thermal isolation by water storage roofing, outside are the package of parapet 1, structure distribution from bottom to top are as follows: roofing 2, waterproof Layer 3, waterproof protective layer 4, insulating layer 5, heat insulation protecting layer 6, wherein heat insulation protecting 6 is wavy surfaces, is at each row's trough For a water storage ditch 8, it is provided with drainage hole 9 at each row's wave crest, secondary drainpipe 10 connects the drainage hole 9 of each column. The both ends of roofing are arranged in main drainpipe 11, are connected with secondary drainpipe 10 and building downpipe 12.6 surface of heat insulation protecting layer is set There is one layer of water barrier 7, is used for 8 waterproof of roofing water storage ditch.

Waterproof layer 3 described in the utility model first clears up 2 table of roofing using SBS modified asphalt waterproof coiled material, before paving The sandstone fragment in face, then uses fire curing paving coiled material, paving to parapet 1 while when need Yan Qiang while paving vertically upward, it is super Final 7 surface of water barrier at least 30cm out；

Waterproof protective layer 4 described in the utility model can be selected C20 pea gravel concreten and pour on waterproof layer 3, is used for Protect waterproof layer 3, pour before must close inspection waterproof layer 3 whether have breakage, crack, overlap joint it is not tight the problems such as, pour answer sternly Lattice control casting method and the concrete rate of outflow, avoid damage to coiled material, receive that light is levelling to must assure that flatness after pouring, after being The laying of continuous insulating layer 5 carries out levelling；

Insulating layer 5 described in the utility model is uniformly laid on waterproofing protection using XPS extruded sheet as insulation board On layer 4, substrate surface should be cleaned out before laying；

Heat insulation protecting layer 6 described in the utility model, equally optional C20 pea gravel concreten, upper surface is waveform, Opening profiled sheet can be used and do template, main drainpipe 11 and time drainpipe 10 arrange in advance respectively, pour and be embedded in heat preservation It should be noted that in protective layer 6, when pouring and avoid damage to extruded sheet and avoid blocking drainage hole 9；
