Description
Technical field
The utility model relates to house waterproof, discharge structure and the job practices of building field, the double-deck waterproof double-layer drainage of specifically a kind of heat insulation house surface structure
Background technology
Roof leakage is the generality persistent ailment on puzzlement building circle, it is the problem that the People's Government, industry and broad masses relatively are concerned about, each R﹠D institution and waterproof producer have developed many novel waterproofing materialss, relevant unit, department also sum up many waterproofer's methods, but all fail to stop roof leakage.Existing heat insulation house surface waterproofing system is divided into positively fixed type and two kinds of forms of inversion type, the way of positively fixed type roof waterproof is to do waterproof on insulation layer, form of structure is roof panel basic unit → leveling layer → insulation layer → leveling layer → waterproofing course, the shortcoming that this way exists is if waterproofing course has any one seepage, water will flow directly to insulation layer and scurry other positions to the roof, flow to the floor slit and locate to leak down to cause the roof seepage, not only be difficult to find the definite position of seepage this moment, and insulation layer soaks and can cause insulation failure; The inverted roof waterproofing process is to do waterproof below insulation layer, and its structure is roof panel → leveling layer → waterproofing course → insulation layer → topping successively.In fact the topping on the insulation layer does not have waterproof effect, in case cracking, rainwater will lodge in the insulation layer in a large number, even following waterproofing course is effectively non-leakage, insulation layer also loses heat insulation effect.Roofing in actual construction is at last insulation layer with during smearing leveling layer, in case rain, rainwater enters insulation layer, accumulates in the water in the insulation layer, can not dry up for a long time, and water causes roof leakage in the inlet chamber of roof panel slit.Therefore, usually can occur not raining even strange phenomenon that sunny roofing also leaks.
Chinese patent 200710202498.X discloses " a kind of thermal insulation waterproof roof covering gas-guiding drainage system " its structure and inverted roof waterproof construction basically identical; fundamentally do not solve the problem that the inverted roof topping ftractures and leaks easily; though in insulation layer, added a bleed gutter that communicates with the rainwater pipe; can discharge the big portion ponding that is trapped in the insulation layer; but fail fundamentally to solve roof leakage; also bring simultaneously a problem; that is exactly when roofing runs into big rainwater; because the bleed gutter in the insulation layer communicates with the rainwater pipe; rainwater on the roofing just has the danger of flowing backwards and entering insulation layer by the bleed gutter; this situation appears; one meets heavy rain; insulation layer just may pour in down a chimney into water, causes roof leakage.The heat insulation house surface of this patent is not provided with stack in addition, causes the steam in the roofing heat-insulating layer not discharge.
Summary of the invention
The purpose of this utility model is at the deficiencies in the prior art, provides the double-deck waterproof of a kind of employing to set up defences, the double-deck waterproof double-layer drainage of a kind of heat insulation house surface structure of two cover discharge structures, and this topology layout is reasonable, and anti-drainage effect is remarkable.
Realize above-mentioned purpose by the following technical solutions:
The double-deck waterproof double-layer drainage of a kind of heat insulation house surface structure comprises roof panel, last leveling layer, following leveling layer, waterproofing course and insulation layer,
Described waterproofing course is divided into bottom waterproofing course and surface layer waterproofing course, its arrangement architecture is from the bottom to top successively: reinforced concrete roof board, bottom cement mortar screeding layer, the bottom waterproofing course, insulation layer, surface layer cement mortar screeding layer and surface layer waterproofing course, on heat insulation house surface, be arranged with two cover water-proof drainage systems: a cover is a bottom water-proof drainage system, another set of is surface layer water-proof drainage system, described drainage system mainly is made up of gutter and gutter spout funnel, gutter is arranged on bottom waterproofing course and the surface layer waterproofing course, two gutter left sides of bottom waterproofing course and surface layer waterproofing course, right septum, independent separately, on, under stagger, be set up in parallel, the pipe bottom is inserted in the gutter spout funnel respectively, form the double-deck waterproof double-layer drainage of roofing structure, described gutter spout funnel is positioned at and outdoorly is communicated with main drain;
Described bottom cement mortar screeding layer is provided with many transverse row channelings, several vertical exhaust ditches, many transverse row channelings and several vertical exhaust ditches that vertically is provided with connect, infall at vertical, horizontal exhaust ditch is provided with the roofing air exit that communicates with atmosphere, the roofing stack is arranged on the deck of bottom cement mortar screeding layer, be positioned on the roofing air exit, the tube wall that passes the roofing stack of insulation layer is provided with steam vent, and the water in the insulation layer is discharged through the roofing stack by steam vent.
Compared to existing technology, the utility model adopts the form of structure of two-layer waterproof and two cover drainings at the insulation layer upper and lower surface, has solved many common faults that heat insulation house surface conventional waterproof way occurs.The utility model bottom waterproofing course be waterproofing course also be vapour barrier, it can stop from indoor moisture and enters roofing system by roof panel.The utility model has solved in the rainy season waterproof construction, to run into rainy day roofing heat-insulating layer water inlet, and must to do the difficult problem of waterproofing course in order trying to meet the deadline for the project.The bottom waterproofing course thorough water and the moisture of having blocked from up and down be set.Even roofing heat-insulating layer is met the rain water inlet, the water that enters in the insulation layer can be discharged along the bottom drainage system, along the heat insulation house surface stack, remains in moisture in the insulation layer and can vaporize gradually and drain.For this reason, the long-term building circle heat insulation house surface leakage problems that perplexs is readily solved.The utility model preferably resolves the difficult problem of roof waterproof and insulation, has remedied the deficiency of existing waterproof technique and waterproof effect.
