Abstract
The invention discloses a leakage-proof construction method for building roofs. For the cracks at the building roof of prefabricated plate or cast-in-place structure, the method comprises the following steps of: cleaning the cracks by water; pouring an absorbent resin in the cracks by a high-pressure pump or mixing a sodium methane-siliconic alkoxide and a polyethylene by the weight ratio of 8:1 uniformly and filling the mixture in the cracks; coating a polyisobutene on the upper surface of the absorbent resin till the thickness being of 2-3mm; and covering the upper surface by a fiberglass cloth. For the leakage at the top of the building due to missing edge or corner and unevenness on the roof surface, the method comprises the following steps of cleaning up the roof surface, using a polyvinyl alcohol cement mortar, mixing the sodium methane-siliconic alkoxide as well as a water (8 weight parts) uniformly and spraying the mixed solution on the roof surface; mixing the sodium methane-siliconic alkoxide and water by the weight ratio of 1:8 uniformly and mixing the mixed solution with the cement mortar material by the weight ratio of 1:2 uniformly, and smearing the mixture on the roof surface till the thickness being of 8-12mm. The method has the advantages that the roof with the leakage supplemented has long service life ranging from 15 years to 25 years generally.
Description
Technical field
The present invention relates to the architecture construction method, especially relate to leakage-proof construction method for building roofs.
Background technology
Building especially civilian construction adopts the tectonic type on precast plate or the flat roof of cast-in-situ steel reinforced concrete more, therefore usually the crack occurs in use for some time and causes and leak; Or the micropore and the pore that form in the hydration and hardening process owing to roof cement produce seepage.To above-mentioned seepy question, traditional leakproof, craft leakage mending method are taked the pattern of scalding with pitch at roof surface more; The deficiency that this method exists is to use the life-span short, is generally 3-5.
Summary of the invention
The object of the invention is to provide a kind of leakage-proof construction method for building roofs of simple, environmentally-friendly sanitary.
For achieving the above object, the present invention can take following technical proposals:
Leakage-proof construction method for building roofs of the present invention, carry out according to following step:
Category-A, for the crack, building roof of precast plate or cast-in-place structural:
The first step: water is gone out cleaning with the dirt in the described crack, surface dust, mud foreign material;
Second step: after treating the crack drying, adopt high-pressure pump that water-absorbing resins is poured in the crack; Or adopt methyl silicon sodium alcoholate and polyethylene to mix the back filling in the crack according to 8: 1 weight portion ratios;
The 3rd step: polyisobutene is applied to the water-absorbing resins upper surface, and thickness is 2-3mm;
The 4th step: the glass wool cloth covering is got final product with upper surface;
Category-B, for owing to roof surface truncation, building top seepage that arrisdefect is rough and uneven in surface to be caused:
The first step: roof surface is cleaned out:
Second step: adopt polyvinyl alcohol cement slurry or mortar to repair;
The 3rd step: get and be sprayed at roof surface after water that methyl silicon sodium alcoholate adds 8 times of weight portions mixes;
The 4th step: methyl silicon sodium alcoholate and the water ratio according to 1: 8 weight portion is mixed, mixes the stand, back with the cement bonded sand slurry according to 1: 2 weight portion ratio then and be put on roof surface, thickness 8-12mm gets final product with trowel pressing receipts light.
Described water-absorbing resins is a polyacrylic acid sodium salt.
In the described category-B the 4th step is: methyl silicon sodium alcoholate and the water ratio according to 1: 8 weight portion is mixed, mix the stand, back with the cement bonded sand slurry according to 1: 2 weight portion ratio then and be put on roof surface, thickness 8-12mm, flatten receipts light with trowel, the polyisobutene of 2mm thickness is smeared at the stand then, gets final product at its surperficial layer overlay glass wool cloth.
The invention has the advantages that the roof long service life after the mending-leakage, generally between 15 years-25 years.Water-absorbing resins is poured in the crack,, therefore effectively stoped the crack to leak because strongly hydrophilic groups such as its carboxyl that contains, hydroxyl have water-soluble expansion function; If adopt methyl silicon sodium alcoholate and poly mixed material filling in the crack, not only brought into play and generated methylsiloxane under methyl silicon sodium alcoholate and Carbon Dioxide in Air and the water effect, polycondensation reticulates the methyl silicon resin waterproof film, infiltrate micropore, the pore of plugging cement mortar inside in the roof, improve anti-permeability performance; Simultaneously brought into play the powerful caking property that polyvinyl alcohol has, oil resistant abrasion resistance again, utilized polyisobutene to possess good heat-resisting, UV resistant, chemicals-resistant and weather-proof and possess permanent adhesive, the roof after the mending-leakage is prolonged application life.
