Description

[Detailed Description of the Invention] [Field of Application of the Invention] This invention relates to the floor structure of a large-scale stationary drying device used for drying articles with relatively large areas such as veneers and slate boards.

[Conventional technology and problems]

As shown in Fig. 1, in conventional large-scale stationary drying equipment, a floor section 5 is constructed by applying a thick layer of concrete mortar between foundations 1 and 1' made of concrete or the like.
Generally, walls and ceilings are made by connecting thick wall panels made of heat insulating material sandwiched between iron plates on both sides and ceiling panels 3 and 4. In the figure, numeral 2 indicates an article conveying device.

The reason for this is that in the case of veneer drying equipment, the internal temperature reaches a high temperature of around 200 to 300 degrees Celsius, debris such as wood chips can easily burn inside and cause a fire, and water must be poured from time to time. .

However, the conventional floor section 5 made of only a concrete mortar layer has excellent heat resistance and water resistance, but has poor insulation properties, and a large amount of heat is dissipated from the floor section 5 to the outside of the drying device, resulting in drying with poor thermal efficiency. It had become a device.

[Purpose of invention]

This invention was made in view of the above-mentioned problems, and provides a floor structure for a drying device that is excellent in heat insulation, heat resistance, and water resistance.

[Structure of the idea]

This idea consists of a foundation 1 protruding from the ground surface 6,
A plurality of ALC plates 7 are placed one after another so as to provide a space 9 with a height of 10 mm or less between 1', and a metal plate 10 having large irregularities is placed on the top surface, and a metal plate 10 with large irregularities is placed on the top surface. Cement mortar layer 11
The present invention relates to a floor structure of a drying device characterized in that the floor structure is coated so that the surface is flat.

Hereinafter, this invention will be explained in detail with reference to the drawings which are examples.

FIG. 2 is a sectional view of a drying apparatus according to an embodiment of this invention, and FIG. 3 is an enlarged sectional view of the floor thereof.

In the figure, reference numerals 1 and 1' denote foundations protruding from the ground surface 6, which are usually made of concrete or the like.

As for the structure of the floor, first the first ALC board 7 is placed so as to leave a space 8 between the foundations 1 and 1'.
Furthermore, a second ALC board 7 is placed on the top surface to form a space 9 with a height of 10 mm or less, and then a third
A plurality of ALC plates 7 are placed one after another so as to form a space 9 having a height of 10 mm or less.

The ALC board 7 used in this invention is a lightweight aerated concrete product with reinforcing bars arranged inside and cured with high temperature and high pressure steam, with a thickness of 70 mm to 150 mm, a width of 600 mm, and a width of 600 mm.
It is a plate material with a specific gravity of about 0.5 and has a length in the range of 1800mm to 3500mm.

In this example, the thickness is 100mm, the width is 600mm, the length is 3000mm,
Two ALC plates with a specific gravity of 0.5 were used.

The height of the space 8 between the ground surface 6 and the ALC board 7 may be any suitable height, but the height of the space 9 provided between the ALC boards 7 must be 10 mm or less.

The height of the space 9 is set to 10 mm or less in order to prevent air convection within the space and maximize the heat insulation effect of the air layer. Note that the space 9 can be easily formed by arranging iron rods 12 having a diameter of about 10 mm or less on the upper surface of the stacked ALC plates 7 at appropriate intervals.

In this example, we use an iron rod with a diameter of 8 mm and a height of 8 mm.
created a space of

A metal plate 10 having a large uneven portion is placed on the uppermost surface of the laminated ALC plates 7, and a cement mortar layer 11 is further coated on the upper surface so as to form a flat surface.

In this invention, the reason why the metal plate 10 having a large uneven part is placed on the top surface of the laminated ALC plate material 7 is that the metal plate itself is made of a material with excellent heat resistance, and the uneven part of the metal plate 10 This is to further improve the heat insulation effect of the floor by forming a heat insulation layer 13 of air between the ALC board 7 and the ALC board 7 placed thereon.

In addition, the metal plate 10 having large irregularities used in this invention includes corrugated iron plates and roof decks in which the cross section has corrugated or angular irregularities and the irregularities extend in the longitudinal direction, as well as the entire metal plate. An embossed iron plate with embossed irregularities can be used.

In this example, the thickness is 0.25mm, the width is 762mm, and the length is 1820mm.
A zinc corrugated iron plate 10 with a wave height of 18 mm and a wave interval of 76.2 mm was used.

The cement mortar layer 11 is an ordinary mortar made by mixing ordinary Portland cement or blast furnace cement with silica sand and water. Incidentally, it is also possible to prevent cracks that are likely to occur in the mortar layer by covering the mortar layer with lath mesh, wire mesh, or the like. In this example, the mortar layer 11 is made by adding 3 parts by weight of silica sand and water to 1 part by weight of ordinary Portland cement.
It was formed to a thickness of about 800 mm and a flat surface.

[Effect of idea]

The floor of the drying device of this invention has the above structure, so the top layer of cement mortar provides heat resistance and water resistance to the floor surface, and the metal plate with large unevenness in the lower layer provides heat resistance. The air layer formed between the ALC board and the ALC board improves the insulation performance of the floor. Furthermore, ALC plates are lightweight and have excellent heat resistance and heat insulation properties, and the air spaces formed between ALC plates are narrow spaces of less than 10 mm in height that do not cause convection, making them extremely insulating spaces. Due to the synergistic effect of the constituent materials of each layer mentioned above, the floor of this invention has excellent water resistance, heat resistance, and insulation properties, and is inexpensive and easy to construct. .
