Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method for molding a decorative block having a heat insulating structure, and in particular to a method for forming a decorative block having a heat insulating structure, and in particular, a method for forming a decorative block having a heat insulating structure. The present invention relates to a method for molding decorative blocks, which is a promising method.

Conventionally, this type of heat insulating block material has been molded by using a foamed concrete material as the molded block itself, or by laminating a heat insulating material on the surface of the block.

However, such conventional methods, especially the use of foamed concrete as the structural material of the building frame, naturally have limitations in terms of load-bearing strength, etc., and in block structures in which insulation materials are laminated, it is difficult to use the laminated insulation materials. Due to the need to protect the material, it is necessary to attach external wall panel materials to the surface of the laminated insulation material, and the insulation material to be laminated is usually installed on the inside surface of the block. It is. Therefore,
In terms of the heat insulation structure, it is inevitable that the building will have an internal heat insulation structure that provides cooling and heat shielding on the inner surface of the structure, which significantly reduces the heat insulation properties.

In addition, in external insulation structures in which foamed polystyrene or foamed polystyrene is interposed between the decorative tile material and the loading block, the intervening resin material may deteriorate over time and may become stuck. There is a risk that the decorative tile material may peel off or fall off, and the adhesive surface may suddenly peel off in the event of a fire or other high-temperature event.

The method of forming a heat insulating decorative block of the present invention was devised in view of the inconveniences of the conventional block materials. By laminating insulation materials and decorative tile materials on the block, there is no need for any external wall construction work such as attaching external wall panel materials to the wall surface of the loading block, which was previously considered difficult due to construction costs. The first object of the present invention is to provide a heat insulating decorative block that allows construction of an external heat insulating structure by simply loading the blocks.

Furthermore, the method for molding the insulating decorative block of the present invention is as follows:
The thickness of the intervening heat insulating material can be set as appropriate to obtain the desired heat insulating properties, and it is possible to provide a reliable heat insulating structure, which was previously considered impossible to improve the heat insulating properties of the block itself. The second purpose is to make it possible to provide a heat-insulating decorative block that is a completely fireproof structure that eliminates inconveniences such as peeling of joint surfaces and cracks due to expansion and contraction caused by changes in temperature and temperature. That is.

In order to achieve such an object, the present invention has a structure in which a molded concrete block is placed between one side or both sides of the concrete block and the inner wall surface of the formwork with tiles or the like. The decorative tile material is placed in the formwork so as to create an intervening gap, and then the decorative surface of the decorative tile material is placed in contact with the inner wall surface of the formwork, and foaming is applied between the block and the tile material. This is a method for forming a heat insulating decorative block characterized by filling and condensing an inorganic material having foaming characteristics such as concrete.

DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of a typical molding method for a decorative decorative block material according to the present invention will be described below with reference to the accompanying drawings. 1 is a concrete block used for constructing buildings, etc. This concrete block 1 has male and female dowels that engage with each other or male and female protrusions and recesses on the joint surfaces of the upper and lower surfaces of the block for the purpose of improving its loading characteristics as well as its heat insulation and sound insulation characteristics. Of course, it is also possible to provide grooves, or to add a pattern as a decorative surface, or to expose a split surface.

Next, 2 is decorative tile material, which is directly stacked.
Items with a staggered pattern or other arbitrary patterns, shapes, and colors are available.

Then, the block 1 and the tile material 2 are arranged in the formwork 3, and the block 1 is placed so that one side is in contact with the inner wall surface of the formwork 3b, which is normally placed on the formwork surface plate 3a. Then, a formwork auxiliary plate 4 having a buffering function such as a rubber material is provided on the other inner wall surface, and the decorative tile material 2 is interposed in the concave surface of this auxiliary plate 4.

Note that a considerable gap is left between the decorative tile material 2 to be interposed and the block 1 to be placed, and this gap is filled with an inorganic material 5 having foaming properties such as foamed concrete. It is made to condense.

The inorganic material 5 is made of various inorganic powders, granules, fiber materials, etc., and a foaming agent suitable for the material is mixed therein, and the inorganic material 5 is made of a material that does not have self-cohesive power. In this case, a synthetic resin adhesive, a curing agent, etc. are appropriately mixed.

In this way, the inorganic material 5 filled between the block 1 and the decorative tile material 2 foams and expands in the filling gap, filling the gap and sticking to the back surfaces of the block 1 and the decorative tile material 2. ,
It condenses and makes the two inseparable.

The insulating decorative block according to the present invention has a unique structure as described above, in particular, it uses an ordinary concrete block as the building frame, has complete external insulation using a foamed inorganic material with excellent heat insulation properties, and has an exterior made of tile material itself. Since it can be used to apply makeup, various excellent effects are exhibited.

That is, in the insulating decorative block according to the present invention, the load-bearing properties of the frame as a structural material are as good as those of ordinary concrete block materials, and the laminated insulation material is then used as a tile material for the exterior material. By providing reliable protection, the insulating decorative block can be made into an external insulation structure with excellent cooling and heating shielding effects, and is equipped with a tile exterior that gives it a luxurious feel. This eliminates the need for any construction work.

In addition, since the block 1, the decorative tile material 2, and the intervening material 5 are all inorganic and have approximately the same coefficient of thermal expansion, there is little problem of deterioration due to temperature changes between cooling and heating. This also reliably prevents the occurrence of peeling and cracks due to contraction and expansion at the joint surfaces of different materials.

In addition, in the insulating decorative block according to the present invention, by using an inorganic material instead of the organic material used in conventional insulating structures, the generation of harmful gases due to heating can be avoided. In addition, there is no risk of burnout, and the structure is completely fireproof, thereby completely eliminating the disadvantages of conventional heat insulating structures.

Incidentally, even if the inorganic material 5 to be filled and interposed is a sufficiently foamed porous material, the porous material is interposed between the decorative tile material 2 and the block 1 and prevents direct passage and movement of air. As a result, the air inside the porous body is almost sealed, and exhibits excellent heat insulation and sound insulation properties.

Furthermore, since the outer surface is covered with the tile material 2, infiltration of rainwater and the like is reliably prevented.
