Technical field

The utility model relates to roof heat insulation water proof building technical field more particularly to a kind of hard polyurethane foam thermal-insulating waterproofs Composite construction.

Background technique

Steel building is because its numerous advantage increasingly becomes the mainstream of modern space structure development, in recent years, steel Structure is more widely used in public building, especially steel building design and function integration, not only designer is allowed to have The space of the richer imagination more makes building more for functionalization, make building structure full of modernization times flavour, practical to prove steel Structural construction has more vast potential for future development in China.

Increasingly the modern architecture of functionalization also creates different special-shaped roofing, also brings more to roofworks Big problem, especially roof heat insulation and waterproofing work.

Raising with people to building energy conservation and waterproof requirement, various waterproof and insulation integrated systems are also being continued to optimize And raising.Various thermal-insulating waterproof materials also all are able to apply and practice in abnormally-structured roofing, but its heat preservation and waterproof performance It always is problem not satisfactory in steel construction abnormal shape roofworks.

It is investigated according to zero point, domestic main cities construction roof leakage rate is 95.33%, and hypogee percolation ratio is 57.51%, interviewed resident is 37.48% by the puzzlement of building leakage, and existing waterproof material has the following deficiencies: one: anti- 399 kinds of water profession atlas, so that waterproofing industry is chaotic, the waterproof idea of many waterproof constructions is not right, and common waterproof idea has Raincoat-type " waterproof idea: having worn one " raincoat " to building, and fatal defects are " channeling waters "；Compared to raincoat-type " waterproof idea, The waterproof layer of " fusion type " waterproof idea " merges " with building structure surface；It " is merged " between waterproof layer and waterproof layer, percolating water Probability differs 1000 times；Two: the selection of waterproof material is not right, and different waterproof materials is suitable for different waterproof positions, waterproof The wrong position of material cannot reach corresponding waterproof effect.

Utility model content

In order to make up for the deficiencies of the prior art, the utility model provides a kind of hard polyurethane foam thermal-insulating waterproof composite junction Structure, using " fusion type " waterproof idea, by hard polyurethane foam thermal-insulating waterproof, water-repellent paint waterproof, waterproof roll waterproof makes The waterproof thermal-insulated effect of structure is good, and setting protective layer can protect polyurethane heat-insulation waterproof layer and not irradiate aging by ultraviolet light The waterproof service life of structure is increased to solve problems of the prior art.

The utility model is achieved by the following technical solution: a kind of hard polyurethane foam thermal-insulating waterproof composite construction, packet Roofing construction sheet is included, concrete surface is equipped in the top of the roofing construction sheet and seals priming coat, the concrete surface is close Back cover coating is equipped with 2, and 2 concrete surface sealing priming coats are setting up and down, and the concrete surface seals priming coat Upper end connect hard polyurethane foam insulation water-proof layer, the top of the hard polyurethane foam insulation water-proof layer is equipped with pea gravel concreten Layer, the upper end of the pea gravel concreten layer connect waterproof coating layer, and the top of the waterproof coating layer is equipped with waterproof roll layer, institute It states and is additionally provided with protective layer above waterproof roll layer.

Advanced optimize ground, concrete surface sealing priming coat with a thickness of 0.1mm, the concrete surface sealing Priming coat is polyurethane closed priming coat.

Advanced optimize ground, the hard polyurethane foam insulation water-proof layer with a thickness of 58-62mm.

Ground is advanced optimized, the staggered reinforcement rod of transverse and longitudinal is equipped in the pea gravel concreten layer, is led between the reinforcement rod Cross sealant connection, the pea gravel concreten layer with a thickness of 118-122mm, the pea gravel concreten layer is C25 microlith coagulation Soil layer.

Advanced optimize ground, the waterproof coating layer with a thickness of 1.5mm, the waterproof coating layer is uncured pitch rubber Glue water-repellent paint.

Advanced optimize ground, the waterproof roll layer with a thickness of 3mm, the waterproof roll layer is poly- for self-adhesive modified asphalt Ester tyre water-proof coiled material layer.

Ground is advanced optimized, the protective layer is ceramic tile layer or terrace paint layer.

The beneficial effects of the utility model are:

One: when roof covering water-proof structure is arranged in the utility model, using hard polyurethane foam insulation water-proof layer, insulation Performance is good: hard polyurethane foam is the foamed material of height closed pore, and rate of closed hole reaches 95% or more；Waterproof performance is good: polyurethane Hard bubble is not connected to mutually since rate of closed hole height, most micropores are in separate state, and rainwater will not seep from the foaming space；It is viscous It is good to tie performance: polyurethane coating hard bubble has excellent self-adhesion, in addition to a small number of organic materials such as fluorinated polyesters ethylene, polyethylene, There is very strong bonding force with the nonmetallic materials such as metal and timber, masonry, glass；It is light-weight: the general bulk density of hard polyurethane foam For 35-55kg/m³, not only can be reduced the weight of insulating layer, but also be able to satisfy the requirement of architectural engineering later process construction；Easy construction Speed is fast: hard polyurethane foam reaction speed is fast, more than ten seconds can foaming, 30 minutes are i.e. hardenable, and construction efficiency is high；Make It is long with the service life: polyurethane foam have excellent aging resistance energy, by covering protection the hard polyurethane foam service life up to 30 years with On；Good in economic efficiency: hard polyurethane foam energy saving as caused by insulation is more at high cost than rigid foam material itself very More times；Safety is fire-retardant: spraying polyurethane flame retardant type foam not only has the characteristics that self-extinguishment, but also meets open fire and only carbonize, non-fusible, It does not trickle, the intensity of a fire can be prevented quickly to spread, greatly reduce fire risk；

Two: the utility model according to " fusion type " waterproof idea, hard polyurethane foam insulating layer with a thickness of 58-62mm, mix Solidifying soil matrix face sealing priming coat with a thickness of 0.1mm, pea gravel concreten layer with a thickness of 118-122mm, the thickness of waterproof coating layer Degree is 1.5mm, waterproof roll layer with a thickness of 3mm, total overall thickness is no more than 190mm, and overall thickness is no less than 180.7mm both will not cause thermal-insulating waterproof performance bad because of too thin, will not too it is thick cause heat insulating and water proof structure too fat to move so that Amalgamation is bad between layers, ingenious in design, and science environmental protection is suitable for wide popularization and application.
