Combined method for water-proof integration and accumulated water drainage of concrete roof structure

Technical Field

A combined method for integrating the water-proof function with the water-draining function of concrete roof structure features that the water-proof function is combined with the water-draining function.

Background

The building waterproof products are many, the method is also many, still seepage, when the roof of taking apart the seepage sees that there is ponding on the structural plane, and the waterproof layer breaks away after soaking. Two problems are to be solved: 1. the water outlet is lower than the structure plane, so that no water is accumulated on the structure plane; 2. the waterproof layer is integrated with the structure and can not be separated.

Disclosure of Invention

When the problem 1 is solved, a drain port tray is made of stainless steel or other materials, the tray is installed at the position of the drain port after steel bars are bound, the size of the drain port tray can be 20-30 mm lower than that of a concrete protective layer, a drain pipe is welded on the tray and extends out of the position below a structural surface, after a concrete roof is poured, a drain pipe is sleeved, integral nodes are all finished by prefabricated products instead of being made in site construction, the quality is reliable, and the gradient of the surface of the structure is made to be 0.2-2%.

When the 2 nd problem is solved, latex cover mesh cloth is mixed into the surface layer when the concrete structure layer is poured, the manufactured structure is provided with a waterproof layer, the manufactured structure can not be separated when being soaked in water, the water outlet is plugged after the structural strength is reached, and the structural roof can be subjected to a water storage test all the time. And then, a non-cured rubber asphalt self-adhesive layer is made, and then the waterproof coiled material is pasted, so that different surface layers such as a heat preservation structure, a greening structure, a manned structure, exposed coiled material and the like can be manufactured in a distinguished manner.

The invention discloses a combination method of water prevention and accumulated water drainage for a concrete roof structure, which comprises the following steps:

s11, manufacturing the tray by using stainless steel or other materials, wherein the turnup 20-30 is the thickness of the concrete protective layer, the middle part is a downpipe, and the length of the downpipe extends out of the concrete roof panel;

s12, mounting the tray after the reinforcing steel bars are bound, pressing the tray on the reinforcing steel bars, and pouring concrete above the flanges of the tray;

s13, wrapping the tray flanging by concrete, and making the slope of the tray flanging upward to be 0.2-2%;

s14, after the concrete roof is poured, the drain pipe is sleeved on the extended stainless steel downpipe.

The combined method of the water-proof integration and accumulated water drainage of the concrete roof structure further comprises the following steps for preventing the blockage of leaves and sundries:

and S21, a disc is arranged between the tray and the downpipe, so that various anti-blocking devices in different shapes can be conveniently installed.

The invention discloses a combination method of water-proofing integration and accumulated water drainage of a concrete roof structure, which comprises the following steps in the integration method of a water-proofing layer and the structure:

s31, when the structural surface is poured and pounded, mixing waterproof latex on the surface and then adhering mesh cloth to make a self-contained waterproof surface layer of the structure;

s32, blocking the water outlet after the structure reaches the strength, and checking the structural surface by water storage;

s33, manufacturing a self-adhesive waterproof layer (such as non-solidified rubber asphalt) on the surface of the non-leakage structure;

and S34, manufacturing a waterproof coiled material on the self-adhesive layer, and selecting the coiled material according to the roof application.

The combined method of the water-proofing integration and accumulated water drainage of the concrete roof structure further comprises the following steps of:

s41, when the composite material is used for a heat-insulating layer roof, S34 selects an aluminum foil self-adhesive waterproof coiled material, a heat-insulating plate is paved on the coiled material, and then a concrete reinforcing bar protection surface layer is made;

s42, when the waterproof roof is used for greening the roof, S34 selects a root-resistant waterproof coiled material, a drainage plate geotextile is made on the waterproof coiled material, and then planting soil is covered on the waterproof coiled material;

s43, when the waterproof material is used for a common roof, S34 selects a butyl waterproof coiled material and a concrete reinforcing protective layer is arranged on the butyl waterproof coiled material;

s44, when the waterproof layer is used for a roof with exposed waterproof layers, S34 selects thick waterproof coiled materials, and the edges are welded firmly by hot air;

s45, waterproof roll material may be alternatively selected.

The combination method of the water-proof integration and the accumulated water drainage of the concrete roof structure is characterized in that the heat-preservation roof and the green roof further comprise the following steps:

s51, reserving a water leakage outlet of the heat insulation layer when the roof is heat-insulated by the S41;

and S52, reserving a water outlet for water leakage of the planting soil when the roof is greened by adopting the S42.

The invention has the beneficial effects that: the water falling port is lower than the concrete surface layer and has a small structure for finding a slope, so that no water is accumulated on the waterproof layer; the combination of concrete structure and water-proof layer and the drainage of water leakage on the surface of water-proof layer can ensure the permanent water-proof quality of roof.
