Abstract

The present invention relates to energy saving pitched roof structure and its waterproof method. Based on the roof rain water permeating characteristic and waterproof structure principle, the roof heat insulating layer is set on down stream cushion, rather than enclosed inside concrete layer, and the heat insulating material is used as the base of middle waterproof layer. The present invention eliminates water deposit in the heat insulating layer. The present invention is a completely assembled structure and has the functions of reliable leakage prevention, simple installation, low cost, long service life and easy maintenance.

Description

Energy-conservation pitched roof structure and waterproof method thereof

Technical field

The present invention relates to a kind of constructional waterproofing technology that is used to be incubated sloping top roofing.

Background technology

The sloping top of domestic and international existing insulation roofing; owing on roofing basis, the sloping top of tradition, increased insulation layer; change textural; make the roofing that has the constructional waterproofing function originally, become material waterproofing, because insulation layer intensity is lower; after adopting the pea gravel concreten topping; make insulation layer be in closed state, ponding occurs at this insulation layer at present, the situation of seepage is more common.Reason is, damaged concrete cover and waterproofing course when counter batten and batten are installed, and the air in the insulation layer expands, shrinks circulation under environment temperature alternation situation, cause suction.Long-term ponding is difficult to volatilization, finally causes the rainwater gravity leakage, roof leakage occurs.Also there is employing directly to carry out the way of the sticking obedient roof tile of mortar; reason is similar substantially; because sticking obedient mortar is difficult to guarantee that tiling bottom mortar is full; same meeting is watt bottom rejected region ponding when rainy; long-term ponding spreads, gathers to insulation layer by roof waterproof layer defects, concrete protective layer defects, finally causes seepage to occur.Before the promotion roof heat insulation was energy-conservation, sloping top roofing seepage seldom occurred by conventional construction, and its main cause is the suction phenomenon that the roofing internal structure does not exist ponding structure and variations in temperature to produce.Since adopting cast-in-situ concrete roofing covering and heat insulating layer; after continuing the oversite concrete topping on the insulation layer, the insulation layer air temperature variations has formed the suction phenomenon, and after seepage occurring; must open concrete cover and insulation layer, waterproofing course again, just can carry out deck and repair.Difficulty is big, and leak source is difficult to find, occur easily repairing repeatedly, and the effect extreme difference, difficult in maintenance, form the seepage knotty problem.Roof leakage causes the user to decorate and loses and dwelling environment destruction.Directly have influence on user benefit.

The continuous improvement of people's habitat condition at present, after raising day by day, the especially commercialize housing and the raising of people's consumption consciousness of people to the requirement of dwelling house waterproof quality, the dispute that leakage problems causes directly has influence on the work of exploitation, management, user's normal life.The improvement of pitched roof seepage is more much more difficult than flat roof deck.Become the knotty problem of building trade.

Summary of the invention

The purpose of the constructional waterproofing structure that the present invention adopts is to satisfy under the energy-conservation requirement condition, sloping top roof waterproof is constructed the improvement of carrying out on the principle, on the basis that does not change tradition construction technical ability, change present material waterproofing into constructional waterproofing, provide that a kind of waterproof is reliable, installation and maintenance is convenient, the structure and the waterproof method thereof of economy and durability.

The technical scheme of energy-conservation pitched roof structure of waterproof of the present invention and waterproof method thereof is:

After top, cast-in-situ concrete slope roof structure is finished, carrying out mortar levelling when plastering, in mortar, mix impervious agent, purpose is the capillary percolation of anti-rainwater, as the bottom waterproof, after mortar solidifies, employing is punched on deck with spacing electric hammer, the degree of depth is not more than 1/2 of Laminate construction thickness, and hammer in the hole after spreading water-repellent paint with the timber wedge of preservative treatment, the position, hole, changes counter batten downstream into and to fill up, more than the thickness 10mm as the nail hole site by the intersection point of counter batten and the batten of design, length and width are respectively 100mm * 50mm, lining is in the batten bottom, and is vertical with the batten direction, is fixed at roofing with the above stainless steel unit nail of length 90mm to have on the deck of timber wedge.Insulation layer adopts polystyrene foam plate, width specifications is pressed the processing of batten spacing scale, be embedded between batten, thickness is selected with the building heat preservation designing requirement, batten thickness must be greater than cystosepiment thickness 10mm, to guarantee that roof tile colludes the extension distance, in order to guarantee the effect of roof heat insulation, between the insulation layer and bottom waterproofing course of eaves oral area position, adopt the open pore polyurethane foam to fill out embedding, purpose is the mobile heat-insulating property that causes of blocks air to descend, and the rainwater that leaks can be gushed roofing by polyurethane foam perforate row again.The polymer cement coating waterproofing is adopted on surface in batten and cystosepiment formation, can adopt coating waterproofing in case of necessity, as the middle level waterproof.Behind paint solidification, before the tile hanging, be modulated into angle between flat cystosepiment of waterproof embedding and the batten with polymer cement, the dead angle that the discrepancy in elevation causes is in case ponding, and tile hanging simultaneously, will watt collude and insert in the waterproof, and whole roof tile forms the surface layer waterproof.According to roof pitch and seismic design requirement, adopt the steel nail fixed roofing tile in case of necessity, even it is fixing to adopt group to prick.

Advantage of the present invention is: adopt above-mentioned constructional waterproofing, rainwater under wind load splash after watt down, can gush roofing by middle level waterproof row, just in case there is constructional deficiency in the intermediate layer waterproof, rainwater, is revealed water and is gushed roofing by the bottom waterproof through open pore polyurethane foam row to the bottom by middle level waterproof fault leakage.In this roof structure, both avoided air to expand and shunk the suction phenomenon that causes, saved the pea gravel concreten topping again, because whole construction course is finished for the assembling mode; therefore easy accessibility in the future safeguarding, spillage of material is little, and economize man-hour; cost is low, good endurance.
