Description

High-rise building roof waterproof structure

Technical Field

The utility model relates to a high-rise building roofing waterproof construction.

Background

The high-rise building refers to a building with more than 11 floors, the roof of the high-rise building is generally flat, the edge of the roof is a concave drainage channel, the roof is formed by pouring concrete, and the roof is easy to crack under the sun and rain, so that water leakage is caused, and a waterproof structure is required to be arranged on the roof. The existing waterproof structure comprises a waterproof layer connected with a roof, and a protective layer is arranged on the outer side of the waterproof layer. The existing waterproof structure is manufactured by firstly coating waterproof paint on a roof twice to form a waterproof layer, and then paving a polymer modified asphalt coiled material on the waterproof layer to form a protective layer, wherein the protective layer is mainly used for preventing the waterproof layer from being damaged by direct irradiation of sunlight.

Because of the asphalt component in the coiled material, the coiled material is generally black, can easily absorb sunlight and is at high temperature, so that the ageing speed of the coiled material is high, the coiled material is easy to damage and crack, the waterproof layer is exposed, the damage of the waterproof layer is further caused, the water leakage of the roof is caused, and the service life of the waterproof structure is short. When the coiled material was laid, can form the handing-over seam between the adjacent coiled material, rainwater and dust can enter into between protective layer and the waterproof layer from the handing-over seam, form the mud dirt, and some plants borrow by the mud dirt and grow at the handing-over seam, and the joint seam can be enlarged to the plant of constantly growing, reduces the protective layer to the protection dynamics of waterproof layer, and the growth of plant still can form the bacterium with rotting, destroys the waterproof layer, and this life-span that also leads to waterproof construction is shorter. According to statistics, the service life of the existing waterproof structure is between 5 and 8 years.

Therefore, the existing waterproof structure of the high-rise building has the defect of short service life.

SUMMERY OF THE UTILITY MODEL

An object of the utility model is to provide a high-rise building roofing waterproof construction. The utility model has the advantage of long service life.

The technical scheme of the utility model: a high-rise building roof waterproof structure comprises a waterproof layer arranged on a roof, wherein a thin film layer, an asphalt layer, a particle drainage layer and a concrete layer are sequentially arranged above the waterproof layer; a circle of coaming is arranged on the outer side of the particle drainage layer, and drainage holes are formed in the coaming; the particle drainage layer is made of gravel with the diameter of 1-2cm, and the diameter of the drainage hole is smaller than that of the gravel.

In the high-rise building roof waterproof structure, the cross section of the enclosing plate is U-shaped, the opening of the enclosing plate faces inwards, and the vertical arm of the enclosing plate is provided with the drain hole.

In the high-rise building roof waterproof structure, the thin film layer is fixed with the asphalt layer, the thin film layer is made of a PE film with the thickness of 0.2-0.4mm, and the asphalt layer is 1-2 mm.

In the high-rise building roof waterproof structure, the concrete layer is composed of a plurality of square concrete blocks, the side length of each concrete block is 2-3m, a hollow rubber strip is arranged between every two adjacent concrete blocks, and the width of each hollow rubber strip is 1-2 cm.

Compared with the prior art, the utility model discloses it is waterproof to have twice, and first waterproof is conventional waterproof layer, and the second is waterproof for the pitch layer, and the pitch layer is separated by through thin layer and waterproof layer, and each other is independent, and when one of them layer produced the crack, the crack of this one deck can not enlarge other one deck to waterproof reliability has been improved, waterproof construction's life has also been prolonged. The top layer of waterproof construction is concrete layer, constitutes the daily walking of personnel of supplying with stable plane, separates into the concrete piece that a plurality of length of side is 2-3m with concrete layer through hollow adhesive tape for concrete layer is difficult for expend with heat and contract with cold and split under the sunshine, and hollow adhesive tape is used for filling the gap between the concrete piece to be used for compensating the heat altered allowance. Through set up the granule drainage blanket that constitutes by the gravel between concrete layer and asphalt layer for water that oozes down from concrete layer can outwards be discharged via the space between the gravel, and a large amount of air remain between the gravel in addition, make granule drainage blanket have good heat retaining effect, thereby maintain the stability of asphalt layer and waterproof layer comparatively invariably, the difference in temperature round the clock of asphalt layer and waterproof layer is little, the stress of production is little, be difficult to the fracture, thereby waterproof construction's life has further been prolonged. Because the granule drainage blanket comprises the gravel, when concrete layer produced the deformation under the difference in temperature round the clock, this deflection can be eliminated through a plurality of gravel's slight roll effect, can not transmit on the pitch layer to make the pitch layer warp along with concrete layer's deformation, the pitch layer is difficult for breaking, this life that has also improved waterproof construction. The pitch layer can be applied paint with a brush and form, and whole no concatenation seam for the mud dirt that rainwater and dust formed can only be stayed in the granule waterproof layer, can not break through the pitch layer and contact the waterproof layer, promptly, when the last plant growth that has of waterproof construction, the bacterium that plant production and rotten formation can not contact the waterproof layer, and the resistant bacterial performance on pitch layer is good, thereby makes pitch layer and waterproof layer basically can not shorten because of vegetation life-span, this life that has also improved waterproof construction. Through the proof of aging test, the utility model discloses a life is more than 20 years.

Therefore, the utility model has the advantage of longer life.

Detailed Description

The following description is made with reference to the accompanying drawings and examples, but not to be construed as limiting the invention.

Examples are given. A high-rise building roof waterproof structure comprises a waterproof layer 2 arranged on a roof 1, wherein a thin film layer 3, an asphalt layer 4, a particle drainage layer 5 and a concrete layer 6 are sequentially arranged above the waterproof layer 2; a circle of coaming 7 is arranged on the outer side of the particle drainage layer 5, and a drainage hole 8 is formed in the coaming 7; the particle drainage layer 5 is made of gravel with the diameter of 1-2cm, the gravel is perlite particles, and the diameter of the drainage hole 8 is smaller than that of the gravel.

The cross section of the coaming 7 is U-shaped, the opening of the coaming 7 faces inwards, and a drain hole 8 is arranged on the vertical arm of the coaming 7.

The thin film layer 3 and the asphalt layer 4 are fixed, the thin film layer 3 is made of a PE film with the thickness of 0.2-0.4mm, and the asphalt layer 4 is 1-2mm in thickness.
