Abstract
The present invention relates to a heat-insulating waterproof integrated roofing structure of buildings and a construction method. A building roof, particularly an energy-saving flat roof for a residential building, is composed of a roof board, a slopping layer, a heat-insulating (air-isolating and waterproof) layer and a protective layer. The present invention has the main construction technique that the heat-insulating layer is spread, and PE boards are glued from top to bottom along one end to form a whole. If a roof has an organized water drainage system, a flashing and draining hole is arranged in a parapet, and vent holes are arranged in a root part for preventing water. The roof has the advantages of simple structure and easy construction, and can save energy by 50% and prevent the water for more than 50 years.
Description
Technical field
The present invention relates to a kind of building roof, Residential Buildings Energy type flat roof deck especially, the incorporate job practices of waterproofing course and insulation layer.
Background technology
The residential building roof waterproof is to belong to one of important technology of builing industry with insulation, causes domestic and international building great master and engineers and technicians' concern and research for a long time.Particularly applying of nearly more than ten years energy-saving building technology has various technical schemes for roofworks waterproof and insulation problem, and organizes and implements, and replaced some traditional practices.The slag structure single as the insulation layer on flat roof changes the perlite double-layer structure of slag and discrete particles into, and the heat preservation technology of the polystyrene foam plate structure that occurred in recent years etc.And waterproof technique is a hundred flowers contend in beauty especially, one excellent situation of weeding out the old and bring forth the new.The three floors of tarred felt and four floors of tar roofing is cancelled substantially in the city, just large scale application as elastic water-proof technology such as SBS waterproof roll, SBC120, polyurethane waterproof coatings.Also have rigid waterproofing technology, siliceous compacting agent, really must control etc.Insulation is bad, the building common fault of water leakage occurs but these technology still have.
At present roof construction and the job practices of using all has weak point, and it mainly shows: waterproof effect is poor, and service life is short, and have 10 years, 3~5 years of also having, What is more hands over then and just leaks.The top layer insulation is poor, roof dewfall in winter, and corner and ceiling intersection also have mouldy phenomenon to occur.Although when design top room establish some radiators than other floors more, problem has unavoidably expended a large amount of energy again more, and to be still indoor air temperature than other floors low the teletostage, summer fever, indoor environmental quality is poor.From construction and cost analysis, construction is complicated, and labor strength is big, and the time is long, one-time construction cost height, and resident family uses investment big for a long time, and the energy waste of country is big, and environment also is subjected to certain influence.
From many aspects, retrieve the roofworks technology of country of some prosperities and quality by all kinds of means than China advanced person.From the waterproof technique analysis, some senior buildings adopt two roads to set up defences, and material expensive, the construction costs height, and reach 25 years service life at most, and the insulation layer cost is also very expensive, and effect is relatively good, but the synchronous world of roofing and major project is still a blank.
Summary of the invention
In a new product promotion conference, comeed up against high pressure P E cystosepiment, it has good heat-insulating property, and its coefficient of thermal conductivity is lower than polystyrol plastic foam plate and polyurethane foam, and airtight, do not seep water, acid and alkali-resistance, fire-retardant, density are big, certain intensity etc. is arranged.We imagine the PE plate is used the effect that can obtain a generation three in roofworkss.Our first step has been carried out material property experiment, insulation, waterproof, trapping, intensity and has been combined with cement mortar, with the various gluing tests that connect data such as intensity.The digital proof PE sheet material of science is to be used for roofworks insulation, waterproof optimal material.Formally use on engineering in August, 1999, and tentatively obtained some technical datas and job practices.
Job practices is fairly simple, is easily grasped by numerous workmans, and can guarantee workmanship.Its key is that miter angle is processed in four sides of holding the thickness of high pressure P E cystosepiment, and using a kind of gluing connecing is that a sealing is whole, and sky is layered on the sloping layer, secondly is the construction technology main points of doing flashing, outfall and steam vent.
The objective of the invention is to: design a kind of novel energy-conservation residential building flat roof deck engineering construction and construction technology, change present flat roof deck engineering construction and job practices, reach the purpose of technological innovation.
The present invention also aims to: implement the flat roof deck engineering construction method that residential building waterproofing course, insulation layer and vapour barrier combine together, reach energy-conservation more than 50%, 50 years the above object of waterproof.
The present invention also aims to: simplify the flat roof deck engineering construction, reduce the purpose of one-time construction investment and in service life, save the teletostage heating cost, save the purpose of refrigeration expense and roofworks maintenance cost summer.

The specific embodiment
Above-mentioned purpose mainly is achieved through the following technical solutions:
Residential building flat bed face waterproof and the incorporate job practices of insulation layer, in Fig. 1: 4 give and do 3 cinder concrete sloping layers above the stress floor, do 2 waterproof (insulation) layer then in the above, four sides of high pressure P E cystosepiment being processed into thickness shown in Figure 2 are miter angle, in three layers of this one deck desirable generations, form by single PE plate.Major technique is the sticking PE plate in shop during construction, as shown in Figure 3, does parapet flashing, outfall earlier.As shown in Figure 4, from top to bottom glue the PE plate on plane again from an end, make it form the integral body of a sealing, sky is layered on above the sloping layer, does steam vent root waterproof then, after the retaining test is non-leakage, as shown in Figure 5, does concrete cover again.
The present invention compares with existing flat roof deck engineering has six advantages:
The one, simple structure has only four layers.And at present flat roof deck is configured to: eight layers of roof panel, vapour barrier, sloping layer, leveling layer, insulation layer, leveling layer, waterproofing course and topping meters.
The 2nd, easy construction reduces by four layers workload and material, and has alleviated labour intensity.
The 3rd, reduce the one-time construction cost.
The 4th, improve service life, waterproof thermal-insulated synchronous with major project.
The 5th, high insulating effect, energy-conservation 50%, save resource, help sustainable development.
The 6th, resident family saves maintenance cost at residence, has also saved teletostage heating fee, the summer expense of freezing, and has improved indoor environmental quality and comfort level.
Claims (1)
1, a kind of roof waterproof, heat preservation technology; especially the live incorporate job practices of waterproof, insulation layer of energy-saving flat roof deck; this roofing is by roof panel, sloping layer, waterproof (insulation) layer, four layers of formation of topping; it is characterized in that waterproofing course, insulation layer and vapour barrier combine together; its method is that miter angle is processed in four sides of high pressure P E cystosepiment thickness; with a kind of gluing connecing is that a whole sky of sealing is layered on the sloping layer, does concrete cover above it.
