Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a heat shielding building structure and its construction method for effectively utilizing the floor surface inside a warehouse such as a cold storage warehouse. It concerns architectural structures and construction methods for blocking invading heat.

Generally, when a building is used as a refrigerated or heated warehouse, panel-shaped heat insulating materials are installed on the inside surfaces of the warehouse, on the upper surface of the floor, and on the lower surface of the ceiling, in order to prevent heat conduction from entering from the outside.

However, such a lining structure not only reduces the storage volume of goods, but also damages the insulation material installed during cargo handling operations, so it is not a durable structure. Due to this situation, insulation materials have recently been installed on the entire outer surface of the building's perimeter walls, and the insulation materials placed on the warehouse floor slabs block the heat conducted from the underground beams through the walls. To do this, the grain was distributed standing up all around the maternity chamber up to the required height of the inner wall surface. However, with such a structure, the floor area is reduced by at least the thickness of the insulation material, and because the shaded containers containing frozen products are stacked with their sides aligned, only the insulation material is needed on the upper part of the body. Even if it could be removed, the effective storage volume within the shield would not have been substantially expanded. Furthermore, in recent buildings where the outer wall and floor are integrally constructed with concrete, the lower part of the insulation provided on the outer surface of the wall is extended below the floor surface, and the inner surface of the wall at the bottom of the floor is They crawled under the floor and glued and fixed the insulation.

This construction method was a demanding process and could not be expected to provide reliable moisture proofing and heat shielding, which was the initial goal.
In the present invention, in order to install the heat insulating material on the inner surface of the lower wall and column from the floor surface, the east side as a floor material support is erected in advance at the inner side of the upper surface of the underground beam and footing with a required interval, This is an architectural structure and its construction method in which a large pulley supporting the flooring material is placed in a bag at the upper east end, and one edge of the flooring material having moisture-proof and heat-insulating properties is attached to the large drawer. It is quick and easy to use, provides reliable moisture and heat insulation, and constitutes a robust and durable heat-insulated building, dramatically expanding the storage capacity of products, and also being used as a structural member during loading and unloading operations. It is possible to use it rationally without damaging it.

Embodiments of the present invention will be described below with reference to the drawings. 1st
The figure shows a part of a reinforced or steel-framed concrete building, in which a footing 2 and an underground beam 3 are installed on a low-floor excavated ground surface 1 excavated to a predetermined depth from the external ground surface. A wall body 4 and a column 5 are cast by pouring joints near the outdoor side of the upper surface of the underground beam 3 and the footing 2, and a pedestal 13 is integrally provided from the outer surface of the underground beam 3. A panel-shaped heat insulating board 6 is stretched on the outdoor surface of the wall 4 via connecting fittings that are projected from the wall surface in advance, and an aggregate material is placed on the surface of the heat insulating board 6. First, a fireproof wall 8 made of a prestressed concrete panel (PC board) or the like is installed over the entire wall. A panel-shaped heat insulating material 9 having a predetermined floor height above the upper surface of the underground beam 3 is stretched on the inner surface of the wall 4 over its entire circumferential length via connecting fittings or an adhesive. Furthermore, the east 11 is erected on the inner side of the upper surface of the underground beam 3 at a required interval. For the east 11, it is preferable to erect reinforcing bars in advance when pouring concrete for the underground beam 3, and then concrete is poured into a formwork surrounding the reinforcing bars. Between the upper end of this east 11 is 1
A large pull 12 made of type steel or H type steel is mounted, and the large pull 1
2, a laminated long lower floor 16 with a moisture-proof material and a heat insulating material interposed therebetween is mounted on the lower surface of one side end of the lower floor 16. The building structure constructed using this construction method does not have any insulation material above the floor surface on the inner surface of the outer peripheral wall, significantly increasing the total floor area of each floor of the building and dramatically increasing the product storage rate. This is a big deal. Heat from under the floor through which outside air is carried is conducted to the walls 4 and pillars via the underground beams 3 and footings 2, but the cooled indoor air is transferred to the walls 4 and pillars 5 facing indoors.
The heat transmitted from below is blocked by the wall portion at the middle height of the heat insulating material 9. Therefore, heat from the outside does not affect the temperature inside the room, which is cooled or maintained at a predetermined temperature. Another embodiment of the construction method of the architectural structure of the present invention will be described.

In FIG. 1, the heat insulating materials 6 and 9 are formed into thick panels made of hard polyurethane synthetic resin foam, and metal plates are bonded to both surfaces of the panel-like foam to provide load-bearing and moisture-proof properties. Use insulation panels to block the The insulation panel 6
, 9 are used as weir plates when concrete is poured into walls and columns, and after removing the shoring (not shown), they form an insulating wall integral with the poured wall. That is, on the upper surface of the footing 2 and the pedestal 13 of the underground beam 3, the insulation panels 6 and 9 are supported with shoring with a required interval as shown in FIG. Place the board. Furthermore, the fixing metal fittings are appropriately protruded inward from the insulation panel.
Thereafter, when concrete is poured and cured, the heat insulating panels 6 and 9 are firmly and airtightly fixed to the wall 4 and the pillars 5. Thereafter, a cylindrical formwork (not shown) is installed to surround the reinforcing bars 101, which had been previously raised upward from the inside of the heat insulating panels 9 on the top surfaces of the footings 2 and underground beams 3 at a required interval, and then the concrete is poured. Drive and form the above-mentioned East 11. The large drawer 12 is mounted and fixed between the upper ends of the east 11 via a formwork. The lower part of the main drawer 12 is fixed to the upper east end by embedding. A lower surface of one longitudinal end of a PC board 17 constituting the lowermost layer of the floor 15 is laid on the main drawer 12.

When layering this PC board 17, a moisture-proof sheet 18 folded from the upper surface to the end surface is placed in advance, and the end surface of the PC board 17 is crimped onto the heat insulating panel 9 surface. Instead of this PC board, a corrugated steel plate may be placed in advance while being pressed against the surface of the wall insulation panel, and then reinforcement may be placed on the steel plate and concrete may be poured. If such a method is used, there is no need to fold the moisture-proof sheet 18 up to the joint with the wall insulation panel. This moisture-proof sheet 18 is preferably made of thick asphalt moisture-proof paper, etc. This moisture-proof sheet 18 prevents water vapor from under the floor from penetrating the PC board 17 or penetrating the PC board 17 from its own part of the heat insulating panel 9. Prevents this from happening and maintains the set indoor temperature.

As shown in FIG. 2, on the lower surface of the pond-side end of the PC board 17 in the longitudinal direction, a steel frame 4 and a beam 22 made of type 1 steel are further installed on the east 21 of the underground concrete beam 20, and the steel beam 22 A military calendar is written.

FIG. 3 shows a case where the lower surface of the longitudinal pond-side end of the PC board is directly attached to the underground concrete girder 23, and the PC boards arranged one after another are butted and attached.
A heat insulating panel 25 is laid over the front surface of the moisture-proof sheet 18 arranged as described above.

This heat insulating board 25 is not made of a metal side plate like the above-mentioned heat insulating boards 6 and 9, but is made of a foamed synthetic resin material such as foamed polyurethane that is resistant to compressive loads and molded into a plate shape. It is. Notches 26 and 27 are formed at the contact portions of the heat insulating plate 25 and the heat insulating panel 9, and a foamed polyurethane liquid 28 is injected and filled with a gun or the like to form an airtight integral body. A waterproof sheet 29 is further laid on the heat insulating plates 25 laid out.

The peripheral portion of this waterproof sheet 29 is bent and extended to the rising portion of the heat insulating panel 9 and its upper end face, and is covered with adhesive. This is because moisture in the thin chamber that enters from the cast concrete layer above it damages the heat insulating material 25. Said waterproof sheet 29
A concrete mortar 30 having the same thickness as the height of the upper green of the heat insulating panel 9 is placed on top to form a finished floor surface.

When an independent column is erected in a warehouse and an underground beam with a width equal to or shorter than the diameter of the column is installed, a heat insulating panel is installed around the underfloor part of the column. While it is fixed by adhesive means, it is preferable to provide an east section having an L-shaped cross section from the side portion of the core support or underground beam, and to arrange a floor on the east section.

As another embodiment, a concrete pedestal may be placed around the pillar from the base of the pillar, and the east end of the pedestal may be integrally erected. In the present invention as described above, a heat insulating material is disposed on the outer surface of the outer circumferential wall of a building, and an inner heat insulating material is disposed under the lowest floor of the inner surface of the outer circumferential wall to form a double heat insulating layer.

Therefore, a slight overflow of outside air transmitted from the lower part of the floor into the storage room through the wall is blocked by heat exchange at the double heat insulating layer portion.
Furthermore, by placing the east end upright on the inside of the inner insulation material, the insulation floor is installed so that it is flush with the upper edge of the inner insulation material, so that the storage room floor surface has been expanded by the thickness of the insulation material around its entire circumference, greatly increasing the storage capacity for goods.

In addition, since the insulation material is not exposed on the inner surface of the surrounding wall of the storage room, there is no need for internal insulation material, and there is no damage to the interior.
In addition, there is no need to provide fire extinguishing equipment for synthetic resin insulation materials. In addition, the present invention does not involve pouring concrete for the floor at the same time as the walls and columns, but instead installs insulating material on the inner surfaces of the walls and columns in advance, and then concretes the concrete from the underground beams through the east. Since the floor is installed at the level of the insulation material, there is no need to crawl under the low and dark floor and install insulation material on the inside of the underground beams and footings, as in the past. This allows for good workability in that the work is carried out sequentially from the bottom upwards, resulting in faster construction and reduced construction costs.
