Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method for waterproofing various flat roofs such as concrete IJ-te.

Flat roofs are waterproofed using waterproof paper or asphalt, but if cracks occur in a concrete roof, for example, the waterproof layer of asphalt etc. will also crack and the waterproofing effect will be lost, which is a big problem. was there.

An object of the present invention is to provide a waterproofing construction method for a flat roof that can solve the problem by providing a buffer layer to prevent cracks from occurring in the waterproof layer even if cracks occur in the flat roof.

The gist of the present invention is to "butt waterproof materials in which a waterproof layer is attached to the upper surface of a buffer layer made of a material that is easily deformed, and then butt the waterproof layers together to bond the buffer layers to a flat roof. The waterproofing material used in the first embodiment of the present invention is constructed as shown in FIG. There is. That is, inorganic O-Me fibers such as glass fibers are piled up and a binder is added to form a mat, which is then compressed to a predetermined density and heated to harden the binder to form a buffer plate. do. Then, cover the surface of this buffer board with asphalt-impregnated paper 3 impregnated with asphalt,
Fold both sides of the asphalt-impregnated paper 3 along the longitudinal direction of the insulation board, and then bend it further and adhere it to the back surface to form the left buffer layer.Reinforce the entire surface of this buffer layer S with glass fibers. A waterproof layer B formed from a reinforced asphalt sheet is pasted, and asphalt reinforced with glass fiber or asphalt with a thin plastic cloth is applied except for the area around the waterproof layer B (hereinafter both are referred to as the reinforced asphalt route). A connecting groove g is formed on the surface of the waterproof layer 7 to which the waterproof layer 7 is not attached.

On the other hand, the knoll material that connects and soles the waterproof materials is formed to have a width that fits into both connecting grooves of adjacent waterproof materials, as shown in FIG.

The sealing material is formed of an asphalt root reinforced with glass fiber or plastic plate made of the same material as the waterproof layer 7.

As shown in FIG. 3, two methods of applying the present invention include, for example, applying waterproofing material to the surface of concrete 1 and roof 10.

--Buffer plates arranged parallel to each other so that their longitudinal directions are in contact)
Glue. In addition, the short sides are butted together and
・Add according to the length of roof/θ. After that, connecting grooves g on both sides formed on the upper surface of each adjacent waterproof material /, -1
, a piece of sol material is fitted in g, and the parts where this sealing material and the sole material of the waterproof layer 7 contact are heated and melted using a burner (not shown), etc., and the joint parts are connected with asphalt. - Waterproof the connecting parts.

In the above embodiment, the waterproof layer B and the waterproof layer 7 are described as being formed separately and attached to each other, but they can be formed integrally. A connecting groove may be formed on the outer periphery.

The first embodiment of the present invention is constructed as described above, and since the surface of the waterproof material is completely formed with the waterproof layer 7 made of reinforced asphalt notebook, it can exhibit a sufficient waterproof effect. Furthermore, since it is reinforced with a reinforcing material, it has sufficient strength.

In addition, since the connecting part of the waterproof material / has not been formed by connecting RFIF, it can be connected with asphalt by heating and melting the knoll material 7 fitted to this connecting part g, thereby ensuring that no intrusion occurs through the connecting part. can be prevented.

My father, the waterproofing material/ is made of a buffer plate 2 whose lower surface is made of inorganic fiber material, so even if a crack occurs in the roof, the buffer plate will not crack and the crack will not affect the waterproof layer 7. In addition to being able to provide reliable waterproofing and sufficient insulation, it is also easy to install, so the work can be completed in a short period of time.

Next, the second embodiment will be explained based on the drawings shown in FIGS. 9 to 3. Similar to the seventh embodiment, a waterproof layer B is pasted on the surface of the buffer layer S, and A waterproof layer 7' is pasted onto the waterproof layer so that connecting grooves g9g are formed only on both sides along the waterproof layer 7' to form a waterproof material.

As for the construction, as shown in FIG. 2, the surface of the concrete roof 10 is similar to the first embodiment.

Waterproofing material so that the longitudinal direction and short side are in contact with each other /, --
Glue one. After that, one knot 7 is fitted into the connecting grooves g1g on both sides formed on the surface of each waterproofing material, and the parts of the sealing material and the waterproofing layer 7' that come into contact with the sealing material are heated with a burner or the like. The joints are melted and connected and sealed with asphalt, and the sole material 7' is stacked on the abutting portions on the short sides and the sole material, and this is heated and melted to form the sole.

Incidentally, the slope of the roof is formed along the surface of the sole material 7' shown in FIG. 3, and rainwater flows along the sole material 7'.

In each of the above embodiments, the waterproof layers B and B'.

7.7' was explained using asphalt as the base material and a thin mat of glass fiber or plastic inserted as a core material, but the invention is not limited to this, and rubber asphalt, formalized Asphalt may be used, and vinyl chloride glue, urethane glue, etc. can also be used, and in short, any material that has waterproof properties may be used.

In addition, although the buffer layer S is explained to be composed of a mat made of layered inorganic fibers7, it is not limited to this, and polyurethane can be used.In short, when a crack occurs in the roof, Easily deformed and the waterproof layer on the top surface
It is sufficient to use one that does not affect 7.

Also, the sole system may be the same as the waterproof layer.
