Description

[Detailed Description of the Invention] This invention relates to a heat insulating laminate made of laminated tiles. The purpose is to propose a heat-insulating tile laminate material that can be used as an external heat-insulating structure for buildings and has excellent heat-insulating properties and fire resistance, as well as high workability.

Conventionally, in order to provide a building with a heat-insulating structure, the conventional method was to lay a heat-insulating material such as glass wool or synthetic resin foam board on the indoor side of a wall or roof structure. However, in this case, since the outer building frame is located outside the insulation material, temperature changes are large due to the influence of outside air temperature.In the case of buildings made of concrete, the thermal resistance is small, and the building frame is Because of its large heat capacity, it requires a lot of energy to control the temperature, and the structure repeatedly expands and contracts with temperature changes, making it prone to cracks and damage to the waterproof layer. For this reason, in recent years, a method has been proposed in which a heat insulating material is laid on the outside of the frame of walls and roofs to insulate the entire frame from the outside. However, in order to create an external insulation structure,
It required a lot of man-hours to install, as it needed to be strong enough to withstand wind and rain, fireproof, and have a watertight structure to prevent the insulation from getting wet and reducing its insulation performance. For example, to make a flat roof have an external insulation structure, you need to apply leveling mortar on the roof slab, then apply a waterproof layer, then lay insulation material, and then add a waterproof layer, protective mortar, concrete, etc. on top of that. It had to be done.

This invention provides a heat insulating tile laminate for external heat insulating structures that eliminates the complexity of construction as described above. This will be explained below with reference to the embodiments shown in the drawings.

The heat insulating tile laminate shown in FIG. 1 is constructed by laminating and integrating tiles 4 on the surface of an inorganic foam 3 made of foamed obsidian particles 1 and foamed cement 2. Its dimensions are 30cm vertically and horizontally, and 5cm thick.
It is a 10 cm flat rectangular parallelepiped, and can be constructed by laying the tiles 4 on top on the waterproof layer of a flat roof, for example, and fixing them to the building frame using mortar or the like to form an external heat insulation structure.

The inorganic foam 3 made by bonding the obsidian foam granules 1 with foam cement has a thermal conductivity of 0.08 Kcal/m.
hr.° C. and a thickness of about 5 to 10 cm, it is possible to satisfy the usual level of heat insulation requirements. When obsidian is heated to around 1000 degrees Celsius, it expands and becomes a foam made up of fine closed cells, which has excellent heat insulation and water resistance.
An inorganic foam can be produced by filling the gaps between the particles of the foam with a cement slurry to which a foaming agent such as aluminum powder has been added and foaming and solidifying the slurry.

The inorganic foam is not limited to foamed obsidian particles or foamed cement. For example, an expandable glassy rock such as pearlite may be heated to form a glass foam, and this may be bonded with foam cement to form an inorganic foam. Further, reinforcing bars such as reinforcing bars may be provided as necessary. If the inorganic foam of this invention has a thermal conductivity of 0.12Kcal/m.hr.℃ or less and a compressive strength of 5Kg/cm2 ^{or more} , it can satisfy the insulation performance, installation strength, and walking resistance of the upper surface. suitable. Most preferred is an inorganic foam made of obsidian foam bonded with cement foam.

There are various ways to manufacture this thermal insulation tile laminate, but for example, the tiles are laid out on the bottom of the formwork with the back side facing up, reinforcing bars are placed as necessary, and granular or lumpy It is obtained by filling foamed particles such as obsidian, pouring foamable cement slurry into the gaps between the particles, and foaming and hardening the cement slurry. In this case, it is preferable to make the volume ratio of the foamed granules as high as possible, for example, 50% or more, since a bulk density of 0.4 g/cm ³ or less and high heat insulation performance can be obtained. Furthermore, even if the laminate is cured with high pressure steam after being demolded, it remains firmly attached to the inorganic foam and will not separate from the tile.

The tiles used in this invention are of cement concrete, porcelain, solid wood, etc., and are not particularly limited. However, if it is installed on a pedestrian rooftop, etc., it must be able to withstand the walking load.

The size and shape of the tile laminate of this invention can be appropriately selected within a range that is convenient for handling and construction. If the vertical and horizontal dimensions are large, transportation and handling will be inconvenient, while if the dimensions are small, construction will take a lot of effort. The shape is generally a flat rectangular parallelepiped. When installed, in order to ensure tight joints between the joints and maintain high watertightness, if necessary, for example, as shown in Figure 2, protrusions that fit into each other may be installed along the longitudinal direction of the inorganic foam at three positions on the thickness side. The striations 5 and grooves 6 may be provided so as to form a tongue-and-groove structure. Alternatively, a joint structure may be used. In addition, when fixing the laid laminated materials with mortar, asphalt, synthetic resin, synthetic resin latex, etc. are mixed into the mortar to improve water resistance.
Bonding with synthetic resin, cement, etc., and filling with fillers to improve watertightness are highly effective.

This idea has the above structure, and the inorganic foam containing natural glass foam and cement has low thermal conductivity, and the tiles are laminated on the surface, so it has high heat insulation performance and is fireproof and noncombustible. There is. In addition, the inorganic foam can be installed simply by laying it on the surface of the building frame waterproofing layer and fixing it with mortar, etc., making it easier to work with compared to the construction of conventional external insulation structures, and easily creating a highly watertight structure. It will not get wet and cause a drop in insulation performance. Tiles can be firmly bonded to inorganic foam containing cement.
It does not peel off even after high-pressure steam curing, and the inorganic foam on the back side is resistant to deterioration, so it can withstand long-term use.
