【0002】
【従来の技術】
デッキプレートにコンクリートを打設し、下地乾燥後、それぞれの工法の防水を行う。又は、デッキプレート上に耐火木毛板を貼り、シート防水又は断熱材を貼り塗膜防水の工法が採用されている。その結果、屋上にかかる荷重も多く工期はバラつき、防水のクレームによる事故も多く、コスト面にも問題が生じている。
【0003】
【発明が解決しようとする課題】
デッキプレートにコンクリートを打設又は床板を貼る工法の場合、コンクリートの重量又、勾配取りのモルタル等、相当の荷重がかかる。また、コンクリートの養生、乾燥の時間、耐火、断熱材の吹付等に必要とする日数等による工期的な面とコストの部分、又は下地を機械的に固定している塗膜防水では、輻射熱での下地鉄板の伸縮、耐候性からの問題を考慮した場合、相当の膜厚を確保しなければならない。屋上にかかる荷重を比較した場合、ALC床板で116kg/m2、本発明の工法で24.5kg/m2である。本発明は、屋上軽量化、耐火、断熱、工期短縮、コスト低減化を解決できる下地一体化された防水工法である。

TECHNICAL FIELD OF THE INVENTION
The present invention relates to a lightweight fire-resistant, heat-insulated rooftop asphalt waterproofing method that is integrated from the groundwork to the waterproof by a combination of a fireproof deck plate, a hard urethane foam, and a laminated method of asphalt waterproofing.
[0002]
[Prior art]
Concrete is poured into the deck plate, and after the base is dried, waterproofing is performed for each method. Alternatively, a fireproof wood blank board is stuck on a deck plate, and a sheet waterproofing or heat insulating material is stuck, and a coating film waterproofing method is adopted. As a result, the load on the roof is large, the construction period varies, and there are many accidents due to the claims of waterproofing, thus causing a problem in cost.
[0003]
[Problems to be solved by the invention]
In the case of a method of placing concrete on a deck plate or attaching a floor plate, a considerable load is applied to the concrete, such as the weight of the concrete and a mortar for sloping. In addition, due to the time required for concrete curing, drying time, fire resistance, the number of days required for spraying insulation, etc. Considering the problems of expansion and contraction of the underlying iron plate and weather resistance, a considerable film thickness must be secured. When the load applied to the roof is compared, it is 116 kg / m2 for the ALC floorboard and 24.5 kg / m2 for the method of the present invention. The present invention is a waterproofing method with an integrated base, which can reduce rooftop weight, fire resistance, heat insulation, shortening the construction period, and reducing cost.
[0004]
[Means for Solving the Invention]
According to the present invention, a 50 m / m (25 m / m + 25 m / m) hard urethane foam is fixed on a fire-resistant deck plate by using an epoxy-based adhesive and stainless steel screws in combination to ensure the pressure resistance and the heat-insulating number of the fire-resistant structure. You can. In addition, since the asphalt waterproof layer is applied to a roofing base of a modified asphalt system with a high tensile strength, it can sufficiently cope with various movements of the structure and changes in the base due to radiant heat. For the rising part, fireproof and heat insulation can be cleared by sticking fireproof wood blanket and hard urethane foam. For the rising top plate part, we adopt a discarded sash on an iron plate to attach different materials such as C type steel, fire-resistant wood blanket, heat insulating material, outer wall material, etc. For the closing part, we used Kanou-shaped caps.
[0005]
DETAILED DESCRIPTION OF THE INVENTION
As shown in FIG. 1, rock wool is filled in the deck plate of the wall-side refractory section and the kerf of the wall surface.
[0006]
As shown in FIG. 2, two layers of 25 mm rigid urethane foam are attached to the convex surface of the deck plate. The first layer is fixed with a combination of an epoxy adhesive and stainless steel screws. The number of screws is 1 / sheet (600 × 900). For the second layer, after the first layer is attached and fixed, tides are applied by asphalt and applied.
[0007]
As shown in Fig. 3, at the same time, a fire-resistant wood blanket, iron plate and heat insulating material are stuck on the rising part, and a U-shaped discarded shed is attached to the skirting part. A base that can be used.
[0008]
As shown in FIG. 4, before attaching the base of the aluminum angle cap, a waterproof tape is applied to prevent rainwater due to external capillary action.
[0009]
After the attachment of the hard urethane board, asphalt exposure waterproofing is performed.
[0010]
The waterproof construction method by the above method is suitable for a large roof such as a warehouse or a store, and is not largely affected by weather or the like. Also, from the viewpoint of the laminating method of asphalt waterproofing, it is easy to carry out process control and quality control systematically.
[0011]
【The invention's effect】
The waterproofing construction method according to the present invention is: (1) shortening the construction period; (2) lightening the rooftop; (3) reducing costs; and (4) excellent in practicality having advantages such as reliability by the asphalt waterproofing membrane construction method. is there.
