[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to improvement of an outer wall slab of a refrigerated warehouse.

[0002]

2. Description of the Related Art In a refrigerated warehouse, there is a large temperature difference between the inside of the warehouse and the outside of the building, and a sufficient moisture-proof layer and heat-proof layer must be provided between the structure of the building and the outer wall. However, the outer wall slab and the beam, which is a building structure, have conventionally been attached to each other by bolts through the moistureproof layer and the heatproof layer.

[0003]

Since the above bolts transfer heat relatively well, the temperature of the bolt end portion of the outer wall slab drops, and when the bolt mounting bracket and the outer surface of the outer wall slab are close, At the bolt mounting position on the outer surface of the outer wall slab, this portion tends to be below the dew point temperature, and dew condensation occurs at this portion, and the dew condensation flows and wets the outer surface of the outer wall slab. As a result, dust, dust, or rust on the bolts is attached to this part, which makes the building easily contaminated, and heat loss is also generated, resulting in energy loss. If the bolt rusts and loses its strength, the outer wall slab may fall off. Therefore, if the bolt penetrates the outer wall plate and goes out of the outer wall plate, it is disqualified as the outer wall of the refrigerated warehouse.

The present invention has been proposed in view of the above problems, and an object thereof is to increase the weight and cost of the outer wall slab on the outer surface side of the outer wall slab at the bolt mounting position. An object of the present invention is to provide an outer wall slab for a refrigerated warehouse, which has improved heat insulation effect and can prevent dew condensation.

[0005]

SUMMARY OF THE INVENTION In order to achieve the above object, the present invention is to construct a building structure by a bolt mounting metal fitting which is entirely made of concrete or the like and has a predetermined size and is embedded in advance on the inner surface side. In an outer wall slab of a refrigerated warehouse that is attached to a beam of a body through a bolt, the wall thickness of the outer wall slab component material such as concrete on the outer surface side of the metal fitting of the bolt mounting metal fitting at a necessary width wider than the metal fitting width. In addition, a thickened portion thickened by a necessary thickness is provided.

[0006]

By providing the thickened portion on the outer wall slab in the place where the bolt mounting metal fitting is buried, the heat insulating action on the outer surface side of the outer wall slab of this portion can be improved and dew condensation can be prevented. Further, the thickened portion is only required to be embedded in the bolt mounting metal fitting, and at other portions, the thickness can be reduced as compared with the conventional one, and the overall weight does not increase, but rather decreases. And it is easy to manufacture, and there is no cost increase.

1 (A) is a front view showing an embodiment of an outer wall slab according to the present invention, FIG. 1 (B) is a cross sectional view thereof, and FIG. 2 (A).
FIG. 4B is an enlarged vertical side view of the main part of the outer wall slab installed in a refrigerated warehouse, and FIG.

First, in FIGS. 1A and 1B,
(1) shows an outer wall slab, and (2) shows a bolt mounting metal fitting. The outer wall slab (1) is manufactured by supplying concrete or mortar to the temporary frame and placing it while moving the temporary frame, and the bolt mounting metal fittings (2) are previously embedded in predetermined locations on the inner surface side. Then, the wall thickness of concrete or mortar on the outer surface side of the metal fitting (2) embedded in the metal fitting (2) for bolt mounting is increased by a necessary width that is wider than the width of the metal fitting (2). The thickened portion (1a) is provided. The thickened portion (1a) is formed in a rib shape along the longitudinal direction of the outer wall plate (1) because the temporary frame is moved during the manufacturing of the outer wall plate (1). The strength of the outer wall plate (1) is increased. Therefore, it is possible to reduce the wall thickness and reduce the weight of the outer wall slab (1) except for the bolt mounting bracket (2).

By the way, the cost is reduced by using the conventional thin outer wall slab, but problems such as bad heat loss appearance and rust of bolts remain, and the problem can be solved by using a thick outer wall slab. In addition, the increase in cost and the increase in weight increase the cost of transportation and assembly and the seismic stress, which is uneconomical. In the present invention, only the position of the bolt mounting bracket (2) is thickened in the shape of a rib, so that the manufacturing is easy and the outer wall plate (1)
Since the strength of the outer wall slab is reinforced, the outer wall slab (1) as a whole may be thin and lightweight.

The outer wall slab (1) is shown in FIGS.
As shown in Fig. 4, the beams (5) supporting the refrigerated warehouse floor (4) are interposed by the heat insulating layer (3) and are fastened by bolts (6) respectively, and are provided on the outer upper end of the beam (5). The inner end of the bolt (6) is joined to the angle iron (7), and the outer end of the bolt (6) is attached to the bolt mounting metal fitting (2) embedded in the middle of the thickness of the outer wall plate (1). It is locked. The outer end portion of the bolt mounting bracket (2) in the outer wall slab (1) has an increased thickness portion (1a) thickened by a necessary thickness over a necessary width up to the outer surface side of the outer wall slab (1). Since it is provided, the heat insulation of this part is improved, the heat loss of the refrigerated warehouse is reduced, and it is possible to prevent dew condensation on the outer surface of the outer wall plate (1),
It is also possible to prevent rusting of the bolt (6).

[0011]

EFFECTS OF THE INVENTION According to the present invention, by providing the thickened portion on the outer surface side of the bolt mounting bracket, the heat insulating property of this portion is improved, dew condensation and rusting of the bolt are prevented, and heat loss is reduced. Can be reduced. Moreover, the above effect can be achieved without increasing the weight and cost of the outer wall plate.
