Abstract

(57) [Summary] [Purpose] To improve the heat insulating property of the mounting portion of the mounting bolt 6 to the beam 5 which is the structural material of the cold storage outer wall slab 1 and prevent dew condensation. [Structure] A thickened portion 1a is provided on the outer surface side of a buried portion of a bolt mounting bracket 2 which is previously buried on the inner surface side of an outer wall slab 1.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to improvement of an outer wall slab of a refrigerated warehouse.

[0002]

[Prior 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 barrier and heat barrier must be provided between the structure of the building and the outer wall. However, the exterior wall slab and the beam, which is the building structure, have traditionally been attached to each other by bolts that penetrate the moisture barrier and heat barrier.

[0003]

[Problems to be solved by the device]

 Since the above bolts transfer heat relatively well, the temperature of the bolt end of the outer wall slab is lowered, and when the bolt mounting bracket and the outer surface of the outer wall slab are close to each other, the bolts on the outer surface of the outer wall slab are At the position, this part tends to be below the dew point temperature, and dew condensation occurs at this part, and the dew condensation flows and wets the outer surface of the outer wall slab. As a result, dust, dust, or rust on bolts is attached to this part, which makes it a dirty building, and heat loss also causes 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 slab and goes out of the outer wall slab, it will be 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 without increasing the outer wall slab outer surface side at the bolt mounting position. It is to provide an outer wall slab of a refrigerated warehouse that has improved the heat insulation effect of the above and can prevent dew condensation.

[0005]

[Means for Solving the Problems]

 In order to achieve the above-mentioned object, the present invention is made entirely of concrete or the like in a predetermined size, and is attached to a beam of a building structure through a bolt by a bolt attachment metal fitting embedded in advance on the inner surface side. In the outer wall slab of a refrigerated warehouse, the wall thickness of the outer wall slab component such as concrete on the outer surface side of the fitting of the bolt mounting metal fitting is wider than the width of the metal fitting and only the necessary thickness. It is equipped with an increased thickness.

[0006]

[Action]

 By providing the thickened portion on the outer wall slab in the place where the bolt mounting metal fitting is embedded, 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. In addition, 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. . Also, it is easy to manufacture and does not increase the cost.

【Example】

 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) is a main part in a state where the outer wall slab is mounted in a refrigerated warehouse. An enlarged vertical side view, (B) is an enlarged cross-sectional plan view of the bolt mounting portion.

First, in FIGS. 1A and 1B, (1) shows an outer wall plate, and (2) shows a bolt mounting metal fitting. The outer wall slab (1) is manufactured by supplying concrete or mortar to a temporary frame and placing it while moving the temporary frame, and the bolt mounting metal fittings (2) are embedded in advance at 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) at the place where the bolt mounting metal fitting (2) is embedded 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). As a result, 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, although the cost is reduced by using the conventional thin outer wall slab, the problems such as poor heat loss appearance and rust of bolts remain, and the problem can be solved by using the thick outer wall slab. The increase in product cost, and the increase in weight are uneconomical because the cost of transportation and assembly and the seismic stress also increase. In the present invention, since only the position of the bolt mounting bracket (2) is thickened into a rib shape, the manufacturing is easy and the strength of the outer wall slab (1) is reinforced, so that the entire outer wall slab (1) is A thin and lightweight product will do.

As shown in FIGS. 2 (A) and 2 (B), the outer wall slab (1) is attached to each of beams (5) supporting a refrigerated warehouse floor (4) with a heat insulating layer (3) interposed. It is fastened with bolts (6). The inner end of the bolt (6) is joined to the angle steel (7) provided on the outer upper end of the beam (5), and the middle wall thickness of the outer wall plate (1) is joined. The outer ends of the bolts (6) are hooked on the bolt mounting metal fittings (2) embedded in advance. The outer end of the bolt mounting metal fitting (2) in the outer wall slab (1) has a thickened portion (1a) thickened by a necessary thickness up to the outer surface side of the outer wall slab (1). Since it is provided, the heat insulation of this part is improved, heat loss of the refrigerated warehouse is reduced, it is possible to prevent dew condensation on the outer surface of the outer wall slab (1), and the rust of the bolt (6) is prevented. Can also be prevented.

[0011]

[Effect of device]

 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 can be prevented, and heat loss can be reduced. it can. Moreover, the above effects can be achieved without increasing the weight and cost of the outer wall slab.
