Description
Technical field
the utility model relates to the structure of a kind of free from flaw, leakproof overlarge area basement terrace, belongs to overlarge area basement terrace manufacture technology field.
Background technology
for the construction technology of larger area pea gravel concreten terrace, there is the construction technology of comparative maturity both at home and abroad.But, at present when adopting prior art to construct to overlarge area terrace (area >=10000 of terrace square metre time be overlarge area terrace), the quality problems such as while particularly adopting prior art to construct to overlarge area basement terrace, be easy to occur that terrace sinking, the irregular cracking of terrace, terrace seepage are serious, terrace surface planeness deviation is large, terrace application life is short.Therefore, the preparation method of existing overlarge area basement terrace or not ideal enough.
Summary of the invention
the utility model object is: provide that a kind of terrace is difficult for, not easy to crack and construction easily, reliable and stable, the free from flaw of terrace long service life of construction quality is, the structure of leakproof overlarge area basement terrace, to overcome the deficiencies in the prior art.
the utility model is to form like this: a kind of free from flaw of the present utility model, the structure of leakproof overlarge area basement terrace is, this structure comprises the overlarge area basement terrace that building area is greater than 10000 square metres, this overlarge area basement terrace is concrete self-waterproof floor layer by bottom, the second layer on bottom is pvd layer, the 3rd layer forms for reinforced concrete floor is superimposed with each other for plain concrete leveling layer and the 4th layer, in reinforced concrete floor, be provided with the shrinkage joint that reinforced concrete floor is divided into small-sized integral type reinforced concrete floor, in shrinkage joint, be filled with extruded polystyrene board, upper surface at each small-sized integral type reinforced concrete floor of reinforced concrete floor is coated with one deck polyurethane coating, and be all filled with silicone weather resistant glue in the gap between the polyurethane coating on every two adjacent small-sized integral type reinforced concrete floors.
on above-mentioned pvd layer, be placed with shrinkage pool post, this shrinkage pool post protrudes from the bottom surface of pvd layer, in the shrinkage pool of shrinkage pool post, fill and completely have plain concrete, and shrinkage pool post is supported on concrete self-waterproof floor layer, make to be formed with drainage gap between the bottom surface of pvd layer and the upper surface of concrete self-waterproof floor layer.
the shape of each shrinkage pool post is identical, and the diameter of the orifice end of each shrinkage pool post is 30～50 millimeters, and each shrinkage pool post bottom surface is 35～45 millimeters to the height on pvd layer surface, and the sheet metal thickness of pvd layer is 3～10 millimeters; Shrinkage pool post is evenly distributed on whole pvd layer, and the center to center distance between every two adjacent shrinkage pool posts is 50～100 millimeters.
the above-mentioned shrinkage joint width that reinforced concrete floor is divided into the shrinkage joint of small-sized integral type reinforced concrete floor is 25～35 millimeters.
between the edge of above-mentioned reinforced concrete floor and basement pillar, basement wall or basement drainage ditch, be all reserved with true seam, the true seam width of this true seam is 180～220 millimeters, in true seam, be filled with extruded polystyrene board, at the top seal of extruded polystyrene board, having silicone weather resistant glue.
owing to having adopted technique scheme, the utility model is by combining the material of band drain and plain concrete and several different qualities of microlith steel concrete as bearing the stressed overlarge area basement terrace of vehicular load, and the sandwich boards for construction plastic draining board adopting has changed traditional construction technology, it is placed between building basic unit and surface layer, mode by intensive fulcrum (shrinkage pool post) power transmission, forms whole space interlayer.Structure of the present utility model has the effects such as the cracking of preventing, draining, heat insulation, insulation, sound insulation, threading.The mode of the waterproof technology of existing In Great Basement terrace, its essence is single " water blockoff " mode that adopts, once have tiny crack when terrace, water leaking-in takes care of the pence, and will cause seepage at leisure.The sandwich boards for construction plastic draining board that the utility model adopts can be discharged a small amount of percolating water, forms the combination waterproof type of " stifled-row-stifled ".Make waterproofing course surface not have the water yield, from material and hydraulics two aspects, carry out waterproof simultaneously, therefore can be better, the waterproof quality of more permanent raising building.And the Deepen Design that the pea gravel concreten terrace on top is arranged through shrinkage joint, guarantees that the area of every small-sized integral type reinforced concrete floor is less than or equal to 36 square metres, and reach and prevent cracking at equipment Foundations, post limit and the true seam of metope indwelling.The advantage of the combination waterproof type that the utility model adopts is permanent, and the space interlayer being formed by concrete fulcrum (being filled with concrete shrinkage pool post), has the durability identical with structure.The moistureproof set of antiseepage constructure scheme, forms different anti-rows and combines measure, makes anti-design, the construction that blends integrated engineering reach rational combination, can reduce total cost, effectively improves underground project waterproof quality.In basement bottom board, can obtain applying very widely; Meanwhile, adopt the utility model also can prevent that base plate from getting damp, seeping water, reduction maintenance cost that can be a large amount of.After testing and proof of actual use, adopt the waterproof system of this combining structure of the present utility model, can effectively form different anti-rows and combine measure, make anti-design, the construction that blends integrated engineering reach rational combination, can reduce total cost cost, can effectively improve underground project waterproof quality, by whole layings, really stitch simultaneously, reduce the minute crack of the thermal stresses generation of basement, can make overlarge area basement terrace free from flaw, leakproof, zero defect in the process of using.Therefore, the utility model compared with prior art, the utility model not only has advantages of that the quality of built overlarge area basement terrace is good, terrace is difficult for sinking, not easy to crack, free from flaw, leakproof, and have construction easily, the advantage such as cost is low, construction quality is reliable and stable, terrace long service life.
