The utility model can effectively prevent waterproof roll sag of protecting coating by using above structure, ensure waterproof roll Material is effectively protected for a long time, plays the role of flashing water proof structure permanent effective.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model.
Fig. 2 is the portion the A enlarged drawing of Fig. 1.
In figure:
1-building roofing heat-insulating layer;2-flashing walls;3-parapets;31-elongated grooves;4-waterproof rolls;5— Mortar levelling layer;6-receive header structure;61-waterproof nailing strips;62-the first sealant;7-protection brick walls;8-mortar plastering layers; 91-additional waterproof coiled materials;92-the second sealant.
The utility model is described in further detail now in conjunction with drawings and examples.
Specific embodiment
As depicted in figs. 1 and 2, a kind of building roof parapet flashing water proof structure described in the utility model, including it is general Waterwall body 2, waterproof roll 4, mortar levelling layer 5, receives header structure 6, protection brick wall 7, mortar plastering layer 8, adds and prevent parapet 3 The components such as water coiled material 91 and the second sealant 92.
The construction procedure of the utility model is as follows:
1, pour out the flashing wall 2 of reinforced concrete structure on building roofing heat-insulating layer 1, flashing wall with a thickness of 200 millimeters, concrete uses intensity for C20 concrete, and vertical reinforcement and horizontal reinforcement are HPB300:6@500.
2, based on 2 top of flashing wall, parapet 3 is built using solid brick wall on it, daughter's wall thickness is equal to Flashing thickness of wall body, thickness are 200 millimeters.And an elongated groove 31 is reserved on parapet, the elongated groove location is general The width of 150-200 millimeter above waterwall body and parapet intersection, elongated groove is 60-80 millimeters, is highly 80-100 Millimeter.
3, make with the elongated groove 31 of parapet and its with side elevation in lower portion, flashing wall and building roofing heat-insulating layer Base carries out base treatment to it, and one layer of mortar levelling layer 5 of constructing on it, in flashing wall and roofing intersection, mortar is looked for Leveling does diameter greater than 100 millimeters of circular arc or 45 degree of slope, cement mortar screeding layer with a thickness of 20 millimeters, use ratio for The cement mortar of 1:2 is made.Spray treatment agent on mortar levelling layer.
4, side elevation and 1 intersection paving additional waterproof coiled material 91 of building roofing heat-insulating layer do waterproof in flashing wall 2 Extra play, the additional waterproof coiled material 91 cover entire flashing wall, and upper limb extends upwardly to below elongated groove 20-30 millimeters Parapet in side elevation, and its under originate from the flashing wall and building roofing heat-insulating layer intersection to building roofing heat-insulating layer Middle part extends at least 250 millimeters.
5, paving waterproof roll 4 does waterproof layer, and waterproof roll covers whole building roofing heat-insulating layer 1 and flashing wall 2, and It is extended to on flashing wall in the elongated groove of parapet, and header structure 6, the receipts header structure 6 are received in 31 formation in elongated groove It carries out nail pressing to waterproof roll using waterproof nailing strip 61 to determine, the horizontal space of waterproof nailing strip is 250-500 millimeters, completes nailing strip After nail pressing is fixed, the first sealant 62 is added to do first of encapsulation process at nailing strip.
6, it is close in flashing wall that the waterproof roll 4 of side elevation builds protection in parapet below side elevation and elongated groove Protective layer of the brick wall 7 as waterproof roll, protection tile coping are laterally embedded into the elongated groove.It is solid for protecting brick wall Brick wall body, with a thickness of 60 millimeters.The second sealant 92 is added to do at second sealing in the seam crossing of protection brick wall and elongated groove Reason.
7, one layer of mortar plastering layer 8 is integrally smeared in the interior side elevation of parapet 3 and protection brick wall 7, mortar plastering layer is right It answers the parapet and the intersection of brick wall is protected to form 45 degree of slopes.Mortar plastering layer with a thickness of 20 millimeters, use ratio for 1:2.5 cement mortar be made.
Compared with prior art, building roof parapet flashing water proof structure described in the utility model and its construction technology The advantages of be: using laying bricks instead of traditional mortar as flashing waterproof protective layer, compared with mortar, lay bricks not easily to fall off, can Permanently effective protection is formed to waterproof roll, so that waterproof roll is not easy hollowing, cracked, fall off, is substantially increased waterproof roll Service life, and then improve building roof flashing water proof structure waterproof performance.The receipts head processing of waterproof roll is in addition to using tradition Waterproof nailing strip nail pressing it is fixed after using outside sealant encapsulation process, also by being pressed into protective layer of laying bricks in groove, and recessed Increase second sealant encapsulation process at the hole of slot top, compared with traditional technology, waterproof receipts are not easily to fall off, can effectively subtract The problems such as few flashing water proof structure leakage, cracking.Make in flashing wall and building roof intersection paving additional waterproof coiled material 91 For additional waterproof course, the waterproof quality of intersection is further improved.
