[Detailed description of the device]

[0001]

[Industrial application] The present invention is applied to roofs of buildings, rooftops,
The present invention relates to a waterproof structure for waterproofing, preserving, and rustproofing a balcony, a wall surface, a bathroom, a toilet, a floor, or the like.

2. Description of the Related Art In a conventional waterproof structure for a sheet, as shown in FIG. 3 , a primer layer 22 is formed on a base concrete 21, and a rubber sheet 24 is bonded onto the primer layer 22 via an adhesive 23. Color coating 25 on the rubber sheet 24
It is a two-layer structure that has only been applied, and the topmost color coating 2
When the sheet No. 5 is discolored and deteriorated due to the influence of ultraviolet rays and wind and rain, the rubber sheet 24 is exposed, and the rubber sheet 24 is often damaged and leaks water due to ultraviolet rays or walking of a person. Further, in the case of mortar pressing method, since the rubber sheet 24 is poor in alkali resistance, the rubber sheet 24 put an insulating film 26 as shown in FIG. 4 and mortar 2
It is necessary to insulate them from 7 and there is a problem in terms of time and cost.

Concrete mortar, which is the base for constructing the waterproof layer, shrinks and forms cracks when dried, and cracks elongated with the change of climate cause cracks and peeling also in the waterproof layer. Further, in the conventional waterproof structure of the sheet, since the waterproof sheet is a sticking material, water is infiltrated from the joint portion of the waterproof sheet to cause water leakage. In addition, an organic solvent primer is often used as the primer, and since the adhesives and the like are all organic, they are not compatible with the base concrete and the adhesive strength cannot be maintained for a long time. Therefore, the waterproof layer swells or peels off due to water vapor or the like leached from the surface or the inside of the concrete, which is a serious problem.

[0004]

An object of the present invention The present invention is to provide a, not only has excellent adhesion to the underlying concrete or the like, by using the waterproofing membrane material rich in elasticity and flexibility, the lower land It flexibly responds to expansion and contraction and cracks of the mortar, not only does the insulating film become unnecessary in the mortar holding method, it also has excellent adhesion to the holding concrete, has no joints as the exposure method, and does not crack or peel off. ,
It is to provide a waterproof structure having high strength, excellent heat resistance, abrasion resistance, and durability and capable of maintaining a waterproof effect for a long period of time.

[0005]

[Means for Solving the Problems] The gist of the present invention, which has solved the above problems, is to provide a waterproof structure for a building, in which a main component is a polymer copolymer emulsion , alumina cement, and water.
Contains cement that hardens when contacted and develops a waterproof function.
Reinforcing and Manai hydraulic inorganic material, a waterproof primer layer composed of composite waterproofing membrane material obtained by mixing and aggregate to the lowermost layer, the glass fibers One squid use the composite waterproofing membrane material on the same primer layer forming a waterproof reinforcement layer enclosing the timber, the anti
A waterproof layer made of pre-Symbol composite waterproofing membrane material on a water-reinforcing layer 2
It is a waterproof structure characterized by being stacked in layers and having a protective layer as the uppermost layer in these four-layer waterproof structure.

[0006]

[Operation] Polymer co-weight is applied to the bottom of the waterproof structure according to the present invention.
Alumina cement as an inorganic waterproofing material in the combined emulsion and separately from this , contact with water to cure and develop a waterproofing function.
Waterproof primer layer using a multi-focus type waterproofing membrane material which is mixed with the bone material hydraulic inorganic material which revealed is formed.
The composite coating film waterproof material contains an inorganic material similar to that of the base concrete, so it is well compatible with the base concrete, penetrates and integrates with the concrete, and at the same time also fills cracks and voids and strongly adheres to it. It is possible to prevent swelling or peeling of the layer for a long period of time. Further, since it is also excellent in elasticity, it also acts to protect the waterproof layer by mitigating the effect of expansion and contraction of the underlying concrete or the like due to changes in the external environment. Even if there is water vapor from inside the concrete, the layers do not peel off due to the adhesive strength, flexibility and strength of these layers. Further, by using the alumina cement as inorganic waterproof material, deer also be added to hydraulic inorganic material, heat resistance, wear resistance and durability of the waterproof structure according to the nature of the heat resistance and abrasion resistance possessed by these materials Can be excellent.

EXAMPLES In the present embodiment, by using a composite waterproofing membrane material as a main component a high molecular copolymer emulsion was mixed with the aggregate alumina cement and hydraulic inorganic material, waterproof layer serves on the underlying concrete 11 Is formed on the primer layer 12, and a reinforcing layer 14 including the composite waterproof film waterproofing material and containing alkali-resistant glass fiber 13 as a core material is laminated on the primer layer 12, and further reinforced. A four-layer waterproof structure in which waterproof layers 15 and 16 made of the composite type waterproof film are double-layered is formed on the layer 14, and a protective decorative finish 17 is applied on the waterproof layer 16 as the uppermost layer. It is used not only for rooftops but also for indoor and general wall waterproofing, and has long-term durability against human walking and ultraviolet rays.
In addition, as shown in FIG. 2, if the structure is such that the mortar 18 is placed,
It has a stronger waterproof structure. The lowermost of the primer layer, the alumina cement hydraulic inorganic material, the primer layer 12 since the aggregate is close to the components of the building of the concrete 11 may have adhesive are integrally bonded with the concrete 11, and Primer layer 12, reinforcing layer 14, waterproof layer 1
Since 5 and 16 have flexibility and strength, cracking or peeling does not occur due to expansion or contraction of the concrete 11,
It adheres well to each other and does not swell or peel off. Furthermore, the waterproofness is very good because it is waterproofed by four layers. Further, the reinforcing layer 14 using glass fiber is also excellent in strength. In addition, by including the cement-hydraulic inorganic material, aggregate, it has been utilized the characteristics of these materials heat resistance and wear resistance and durability is improved as a whole waterproof structure.

[0008]

[Effect of the Invention] The waterproof structure according to the present invention has a four- layer waterproof structure, and since the waterproof layer has no joints, it can prevent not only the waterproof layer from being turned up and peeled off, but also ultraviolet rays, wind and rain, etc. Also has long-term durability. The waterproof layer is excellent in adhesion, which is rich in elasticity, so also preventing swelling or peeling of the corresponding waterproof layer to stretch and crack during concrete drying, if the underlying concrete or the like is wet However, it can be installed and the high waterproof effect can be maintained for a long time. Moreover, because of its flexible structure, it can be applied not only to irregularly shaped roofs and roofs for walking and non-walking, but also to waterproofing of balconies and rooms. Also, of glass fiber
The reinforcing layer also enhances the strength of the waterproof structure.
