As shown in Figure 1 to Figure 3, a kind of parapet of roofing water leak-proof structure, including the C20 being cast in outside roofing on side bar 5 Anti- waterproof layer bank 2 and be laid on roofing floor 4 of plain concrete；The height of the anti-bank 2 of C20 plain concrete is 300mm, institute It states and offers several equally distributed expansion joints 21 on the anti-bank 2 of C20 plain concrete, between the expansion joint 21 of adjacent two Spacing be not more than 12m, the depth at the expansion joint 21 is identical with the height of the anti-bank 2 of the C20 plain concrete, and the C20 is plain The anti-bank 2 of concrete and the intersection of the roofing floor 4 are provided with fillet 22, and the anti-bank 2 of C20 plain concrete is equipped with brick Body 1；The waterproof layer include the polymer modified bituminous waterproof sheet material 3 being successively laid with, insulating layer, sloping layer, screed-coat and just Property whole casting layer 7.

The flashing height of the polymer modified bituminous waterproof sheet material 3 is 300mm, offers caulking groove on the brick setting 1 11, one end of the polymer modified bituminous waterproof sheet material 3 is fixed in the caulking groove 11 by pitch ointment.

It is provided with seal groove 6 between the rigidity whole casting layer 7 and the anti-bank 2 of the C20 plain concrete, the seal groove 6 Width is 20mm, is filled with pitch ointment in the seal groove 6, and on the seal groove 6, the two sides of the seal groove 6 smear There is polyurethane water-proof coating 71, the width of the polyurethane water-proof coating 71 is 300mm.

The polymer modified bituminous waterproof sheet material 3, the insulating layer, the sloping layer, the screed-coat and it is described just Property whole casting layer 7 the sum of thickness be less than 250mm.

The insulating layer is extruded sheet；The sloping layer is light aggregate concrete layer, and construction thickness is not more than 60mm；Institute Stating screed-coat is the cement sand bed that ratio is 1:3, is constructed with a thickness of 20mm；The rigidity whole casting layer 7 is C20 microlith coagulation Soil layer is constructed with a thickness of 60mm.

The radius of the fillet 22 is 50mm.

Construction method, comprising the following steps:

Step 1: the first dabbing on side bar 5 outside roofing, the width and roofing of dabbing side bar 5 outside it is of same size；

Step 2: the anti-bank 2 of the C20 plain concrete for pouring 300mm high on side bar 5 outside roofing, and it is anti-in C20 plain concrete The expansion joint 21 of several 10mm wide of indwelling on bank 2, and two tight-closed with sealing material pitch ointment, adjacent expansion joints 21 spacing is not more than 12m, and the depth at expansion joint 21 is identical as the height of the anti-bank 2 of C20 plain concrete；

Step 3: in the intersection of roofing floor 4 and the anti-bank 2 of C20 plain concrete, to smear out radius with cement mortar be 50mm Fillet 22；

Step 4: polymer modified bituminous waterproof sheet material 3 of constructing on roofing floor 4, flashing height is 300mm；

Step 5: successively construction heat-insulating layer, sloping layer, screed-coat and rigidity on polymer modified bituminous waterproof sheet material 3 Whole casting layer 7, wherein the thickness of polymer modified bituminous waterproof sheet material 3, insulating layer, sloping layer, screed-coat and rigid whole casting layer 7 it Be less than 250mm, between rigid whole casting layer 7 and the anti-bank 2 of C20 plain concrete reserve width be 20mm seal groove 6, and with seal Material pitch ointment is tight-closed, and then again centered on seal groove 6, on seal groove 6 and its 150mm's wide respectively constructed in two sides Polyurethane water-proof coating 71；

Step 6: brick setting 1 of constructing on the anti-bank 2 of C20 plain concrete, wherein brick setting 1 and the anti-bank 2 of C20 plain concrete Junction remain for sealing the caulking groove 11 of polymer modified bituminous waterproof sheet material 3 in advance, polymer modified bituminous waterproof sheet material 3 prolongs It reaches in caulking groove 11, and pointing pitch ointment is tight-closed.

The utility model bears down on one and for constructional column is done in centre relative to doing at the top of parapet, easier, cost of constructing Lower and progress faster, bears down on one and the first bar planting of constructional column parapet construction need is done in centre, then build a wall, stay and set horse tooth trough, then close Template, the lower reinforcing bar in the inside of bearing down on one, casting concrete, then conserve；And then eliminate the expense of constructional column and the reinforcing bar that bears down on one；

After the anti-bank of C20 plain concrete of the utility model by pouring 300mm high on side bar outside roofing, with the same material of roofing Material, is all concrete, therefore the wall bottom of parapet and roofing intersection are not easy crack occur, can effectively evade parapet leak Problem.In addition the leak pipe of roofing need to be kept unimpeded, and avoid covering C20 plain concrete because leak blockage causes serious ponding Anti- bank.

Obviously, it is practical without departing from this can to carry out various modification and variations to the utility model by those skilled in the art Novel spirit and scope.If in this way, these modifications and variations of the present invention belong to the utility model claims and Within the scope of its equivalent technologies, then the utility model is also intended to include these modifications and variations.
