Abstract
The utility model provides a limit structure is received to waterproofing membrane facade flashing receives limit department at waterproofing membrane and scribbles the oil polyurethane waterproof coating layer layer of one deck, scribbles one deck benzene board on oil polyurethane waterproof coating layer layer surface and glues, and surperficial hanging is glued to the benzene board has alkaline -resisting net cloth, and alkaline -resisting net cloth surface still scribbles one deck benzene board and glues. The utility model discloses need not to reserve the recess in advance or cornice when concreting, reduce construction process and construction period, reduce cost, labour saving and time saving, the construction quality hidden danger of also having avoided the preparation recess and having corniced and bring. Through the contrast, the utility model discloses 19 yuan of m of cost, and 73 yuan of m of prior art recess formula cost, 38 yuan of m of the formula of cornicing cost, time limit for a project is compared and is used 100m as the example, the utility model discloses an on two work days, the recess formula is 10 half work days, and the formula of cornicing is 9 work days.
Description
Technical field
The utility model relates to the design of building engineering field waterproof construction, especially relates to a kind of building waterproof coil flashing and receives limit structure.
Background technology
Waterproof receives the significant points that head is waterproofing work, is also the weak link of waterproof construction, and non-enclosed waterproof construction is common in engineering, and particularly facade waterproof flashing has been seepage position occurred frequently. In " roofworks inspection of quality specification " GB50207-2012,6.2.14 bar specifies that waterproof coiled material receives the key link that head is the construction of roofing detail structure. As within the scope of eaves mouth 800mm, coiled material should be completely sticky, coiled material termination should be pressed in the groove of screed-coat, and it is fixed that coiled material receipts head applied metal press strip nail presses solidly, and obturages with sealing material; Parapet and gable flashing height should not be less than 250mm, and coiled material receipts head can directly spread under bearing down on one to parapet, and it is fixed to press solidly with metal press strip nail, and obturages with sealing material.
At present, building field also adopts the method in traditional coiled material termination press-in groove, comprises in press-in concrete groove and in infilled wall masonry groove two kinds. Wherein, when former is taked in press-in concrete groove, should reserving groove in advance when casting concrete, mounting template is complicated and template is fixing difficult; When casting concrete, bottom portion of groove concrete cannot arrive because of vibrating spear, uncompacted situation that easily produces to vibrate occurs, after form removal, the common quality defects such as honeycomb and scale easily occur in groove, does not reach waterproof construction requirement, also need to increase reparation groove surfaces of manually plastering, after waterproof requirement to be achieved, just can carry out waterproof construction. Groove Ruo Yinzhimo is insecure and causes distortion, also needs grinding process groove surfaces, ensures groove internal surface flat smooth, meets the bond effect of coiled material. When rear one is taked in press-in infilled wall masonry groove, groove when building by laying bricks or stones, should be reserved in advance, and build by laying bricks or stones and also need to adopt sand-cement slurry floating, because groove size is little, so it is also more difficult to plaster. Infilled wall is constructed groove, wall stability is had impact and there will be the hidden danger of quality such as crack, increase the uncertain factor of construction quality hidden danger.
Also have and adopt coiled material termination paving to the method down or under cornicing of bearing down on one, comprise onsite concrete eaves and rear bar planting casting concrete eaves two kinds. When former takes onsite concrete eaves, model sheetinstallat complicated and cannot primary concreting concrete, should first build the following concrete that cornices, after-pouring cornices above concrete, operation is more and increases construction joint, and special opposite face body of wall, very easily has water leakage at horizontal construction joint place. Cornicing after form removal also should increase polishing operation, increases artificial. When rear one takes rear bar planting casting concrete eaves, should by snap the line, bar planting, tie up muscle, the operation such as Zhi Mo, casting concrete, long in time limit, operation is many, construction is complicated, time-consuming take a lot of work.
Practical novel content
The purpose of this utility model is to provide that a kind of structure is simple, processing ease, duration are short, the reliable waterproof roll flashing of flameproof effect receives limit structure.
For achieving the above object, the utility model provides a kind of waterproof roll facade flashing to receive limit structure, cold primer oil reservoir is scribbled in concrete facade substrate surface, laying water-proof coiled material above cold primer oil reservoir, it is characterized in that: waterproof roll is received limit place and scribbled one layer of oiliness polyurethane water-proof paint layer, scribbling one layer of benzene adhesive for board on oiliness polyurethane water-proof paint layer surface, benzene adhesive for board surface hangs alkaline-resisting grid cloth, and alkaline-resisting grid cloth surface also scribbles one layer of benzene adhesive for board.
Oiliness polyurethane water-proof paint layer is coated in waterproof roll and receives the region that limit place respectively overlaps 80mm-120mm up and down.
Oiliness polyurethane water-proof paint layer is coated in waterproof roll and receives the region that limit place respectively overlaps 100mm up and down.
The utility model scribbles one layer of oiliness polyurethane water-proof paint layer by receiving limit place at concrete facade substrate surface waterproof roll, one layer of benzene adhesive for board is scribbled again on oiliness polyurethane water-proof paint layer, benzene adhesive for board surface hangs alkaline-resisting grid cloth, alkaline-resisting grid cloth surface also scribbles one layer of benzene adhesive for board, without the need to reserving groove when casting concrete in advance or cornice, reduce working procedure and construction duration, reduce costs, time saving and energy saving, it also avoid the construction quality hidden danger making groove and cornicing and bring. By contrast, the utility model cost 19 yuan/m, and prior art groove type cost 73 yuan/m, formula of cornicing cost 38 yuan/m; Duration is compared for 100m, and the utility model is two work days, and groove type is 10 half work days, and the formula of cornicing is 9 work days.
Accompanying drawing explanation
Fig. 1 is section of structure of the present utility model.
Embodiment
With reference to Fig. 1, in concrete facade basic unit 1, table scribbles cold primer oil reservoir 2, laying water-proof coiled material 3 above cold primer oil reservoir, waterproof roll 3 receive limit place up and down respectively overlap 100mm scribble one layer of oiliness polyurethane water-proof paint layer 4, one layer of benzene adhesive for board 5 is scribbled on oiliness polyurethane water-proof paint layer 4 surface, benzene adhesive for board surface hangs the wide alkaline-resisting grid cloth 6 of 200mm, and alkaline-resisting grid cloth surface also scribbles one layer of benzene adhesive for board 7.
Before waterproof coiled material construction, basic unit should clean out, and should take polishing measure, ensure neatly smooth, meet the bond effect of waterproof roll when facade basic unit is concrete member. Waterproof roll should respectively overlap 100mm at receipts limit place brushing oiliness polyurethane water-proof paint after having pasted up and down, makes up waterproof roll and receives a poorly sealed position. Brush one layer of benzene adhesive for board after waterproof paint drying, hangs the alkaline-resisting grid cloth of 200mm width, alkaline-resisting grid cloth surface brush benzene adhesive for board again.
