Abstract

The invention discloses an arc circle double-line roof flashing construction structure which comprises a roof and a wall body perpendicular to the roof. A cement mortar screeding layer, a modified asphalt waterproof coiled material layer, a foam concrete heat preservation and insulation layer, a felt layer, a concrete waterproof layer, a cement mortar combination layer and an anti-slip brick surface layer are arranged on the roof in a paving mode. Cement mortar circular arc transition structures are arranged at connection joints of the roof and the wall body. The arc circle double-line roof flashing construction structure is easy to construct at a whole, and increases comfortable feeling through the arc effect, and is good in waterproof effect.

Arc circle two-wire roofing flashing constructing structure

Technical field

The present invention relates to a kind of roofing flashing constructing structure.

Background technology

For the higher highrise building of Roof Design classification of waterproof, roofworks is most important to the later use procedure of whole engineering.The waterproof operation of roofing flashing is many, it is high to require, and is that more position occurs common quality defect.Especially the connecting portion of roof and wall, be the keypoint part of waterproof, usually adopts the aluminum alloy gusset plate planting of layer to construct in prior art.But its splicing place can not be accomplished tight the arrangement unanimously, easily damages simultaneously, causes infiltration.

Summary of the invention

Technical problem to be solved by this invention just is to provide a kind of arc circle two-wire roofing flashing constructing structure, convenient construction, good water-proof effect.

For solving the problems of the technologies described above, the present invention adopts following technical scheme: arc circle two-wire roofing flashing constructing structure, comprise roofing and the body of wall vertical with roofing, it is characterized in that: be equipped with successively cement mortar screeding layer, modified asphalt waterproof coiled material layer, foam concrete heat-preserving isolation layer, malthoid layer, Concrete Anti water layer, cement mortar setting course, antislid brick surface layer on described roofing, described roof and wall junction is provided with cement mortar arc transition structure.

Preferably, the thickness of described cement mortar screeding layer is 20mm; The thickness of described modified asphalt waterproof coiled material layer is 3mm; The thickness of described foam concrete heat-preserving isolation layer is 120mm; The thickness of described Concrete Anti water layer is 40mm; The thickness of described cement mortar setting course is 12mm; The thickness of described antislid brick surface layer is 8mm.

Preferably, turn on the side of described modified asphalt waterproof coiled material layer and be laid on body of wall, modified asphalt waterproof coiled material layer side top edge is 500mm apart from the minimum altitude of roofing, and the side top edge of modified asphalt waterproof coiled material layer is fixed on body of wall with the@250mm cement nail.

Preferably, at the bottom of described cement mortar arc transition structure comprises the pea gravel concreten arc, smear the thin cement mortar of one deck bottom at the bottom of described pea gravel concreten arc, lay grid cloth on the thin cement mortar of bottom, lay the thin cement mortar of surface layer on described grid cloth.

Preferably, the radius at the bottom of described pea gravel concreten arc is 100mm, and the thickness of the thin cement mortar of described bottom and the thin cement mortar of surface layer is 0.5mm～1mm.

The whole easily construction of arc circle two-wire roofing flashing constructing structure of the present invention, arc circle effect can increase affine sense, and good water-proof effect.

Description of drawings

The invention will be further described below in conjunction with the drawings and specific embodiments:

Fig. 1 is the schematic diagram of arc circle two-wire roofing flashing constructing structure;

Fig. 2 is arc circle mould structure schematic diagram.

The specific embodiment

Fig. 1 shows arc circle two-wire roofing flashing constructing structure of the present invention, roofing 1 surrounding is the body of wall 10 vertical with roofing, arc circle two-wire roofing flashing constructing structure, be equipped with successively cement mortar screeding layer 11, modified asphalt waterproof coiled material layer 12, foam concrete heat-preserving isolation layer 13, malthoid layer 14, Concrete Anti water layer 15, cement mortar setting course 16, antislid brick surface layer 17 on described roofing 1, described roofing 1 is provided with cement mortar arc transition structure 19 with body of wall 10 junctions.

The thickness of described cement mortar screeding layer is 20mm; The thickness of described modified asphalt waterproof coiled material layer is 3mm; The thickness of described foam concrete heat-preserving isolation layer is 120mm; The thickness of described Concrete Anti water layer is 40mm; The thickness of described cement mortar setting course is 12mm; The thickness of described antislid brick surface layer is 8mm.Turn on the side of described modified asphalt waterproof coiled material layer 12 and be laid on body of wall 10, modified asphalt waterproof coiled material layer side top edge is 500mm apart from the minimum altitude of roofing, and the side top edge of modified asphalt waterproof coiled material layer is fixed on body of wall with@250mm cement nail 18.

At the bottom of described cement mortar arc transition structure 19 comprises the pea gravel concreten arc, smear the thin cement mortar of one deck bottom at the bottom of described pea gravel concreten arc, lay grid cloth on the thin cement mortar of bottom, lay the thin cement mortar of surface layer on described grid cloth.Radius at the bottom of described pea gravel concreten arc is 100mm, and the thickness of the thin cement mortar of described bottom and the thin cement mortar of surface layer is 0.5mm～1mm.

Arc circle two-wire roofing flashing construction technology, comprise the steps: in addition
