DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a curing room which is used to promote curing of an uncured concrete product while curing it using steam.

[0002]

2. Description of the Related Art Conventionally, a method of steam curing a large number of uncured concrete products in a curing room filled with high-temperature steam in order to stably dry and cure uncured concrete products so that cracks and the like do not occur during drying. Is widely practiced. This steam curing room uses a number of unit ceiling panels and unit side panels made of FRP panels with excellent heat insulation and durability, and a panel assembly structure in which the inward flanges provided at the edges of each panel are butt-bolted. have.

[0003]

However, the conventional curing room has a problem that water drops condensed on the arched ceiling panel fall on the concrete product and form a drop mark on the product surface. , Its improvement is a challenge.

Normally, the dew condensation on the inner surface of the ceiling panel is designed so that the ceiling panel is arched and guided to the arched end, which is transmitted down to the side panel so as not to fall directly on the concrete product. However, as a result of observation, most of the water droplets condensed on the ceiling panel were transmitted from the ceiling panel to the inward flange, or the dew that grew on the flange itself became water droplets, which merged and were not cured from the lower edge of the flange. It was found that it fell on hardened concrete products and formed a drop mark.

[0005] The present invention effectively prevents a water drop from falling from a ceiling panel to an uncured concrete product being cured in a steam curing room to form a drop mark, and can produce a high quality concrete product without loss. It provides a curing room.

[0006]

SUMMARY OF THE INVENTION A steam curing room according to the present invention is used when assembling a ceiling panel by fastening a plurality of unit ceiling panels to each other by bolting an inward flange provided at an edge of each panel. The above problem is solved by attaching a gutter to the flange for receiving water drops flowing down the flange.

The unit ceiling panel, the flange, and the gutter have an arch shape in the extending direction of the flange. Both ends of the gutter are opened at positions close to the side panel to form a water droplet outlet. In addition, a water retention particle layer is provided on the inner surface of the ceiling panel and / or the outer surface of the gutter to prevent water drops from falling on the product in cooperation with the gutter.

DESCRIPTION OF THE PREFERRED EMBODIMENTS One embodiment of the present invention will be described below with reference to the drawings. FIG. 1 is a cross-sectional view showing a main part of a curing room according to the present invention. In the drawing, 1 is a unit ceiling panel of the curing room, and 2 is both right and left ends (both ends in the frontage direction) of the unit ceiling panel 1. It is a unit side panel to support. The unit ceiling panel 1 is arched in the frontage direction, and mounting flanges 1 a extending horizontally in the depth direction are provided at both end edges in the frontage direction of the ceiling panel 1, and this mounting flange 1 a is attached to the upper end edge of the unit side panel 2. It is placed on the hook-shaped support flange 2a extending horizontally in the depth direction and the flanges 1a, 2a are fastened to each other by the bolt and nut 3.

Also, a unit ceiling panel 1 and a unit side panel 2
Are arranged side by side in the depth direction (the direction perpendicular to the paper surface in FIG. 1).
As shown in FIG. 2, inward flanges 1b, 1b which are bent like hooks and extend in the frontage direction are provided at both end edges (adjacent ends of each panel) facing each other in the depth direction of each panel. By abutting and fastening with the bolts and nuts 4, a ceiling panel having a required area is constructed. Each unit panel 1 has an arch shape in the extending direction of the inward flange 1b,
Along with this, the inward flange 1b also has an arch shape.

Similarly, the unit side panels 2 arranged side by side in the depth direction are bent at both ends (adjacent ends of each panel 2) facing each other in the depth direction so as to extend in the vertical direction. The inward flanges 2b, 2b are provided, and they are butted against each other and fastened by bolts and nuts 7, thereby constructing a side panel having a required area.

The unit ceiling panel 1 has a structure in which a heat insulating member 6 such as a foamed resin is integrally buried in a reinforced plastic panel (FRP: fiber reinforced plastic panel) 5 to provide structural strength, light weight, and heat insulating effect. Have gained.

A gutter 8 having a substantially U-shaped cross section is provided on each of the butted inward flanges 1b, 1b of the unit ceiling panel 2 in the longitudinal direction (frontage direction) of the flange 1b as shown in FIG. And the gutter 8 is placed directly below the butt inward flange.

As shown in FIG. 2, one side plate 8a of the U-shaped gutter 8 is made wider than the width of the other side plate, as shown in FIG.
One flange 1 against which the wide side plate 8a is butted
b, and screw 9 such as tapping screw to each flange 1
b to be attached by screwing it into a cantilevered support structure.

Accordingly, the gutter 8 surrounds the lower end edges of the inwardly facing flanges 1b, 1b at a distance 12 from each other. The gutter 8 has an arch shape synchronized with the arched unit ceiling panel 1 and the inward flange 1b, and extends in the frontage direction. The gutter 8 is formed of a resin such as FRP or a metal plate.

As shown in FIGS. 2 and 3, the inner surface of the wide side plate 8a of the gutter 8 is brought into contact with the bolt head of the bolt and nut 4, and the wide side plate 8a is connected to one of the flanges 1b opposed thereto. The interval 12 is secured between them. Therefore, water droplets transmitted down from the inner surface of the ceiling panel to the flange 1b are:
Without being transmitted to the outside of the gutter 8, it can be reliably dropped into the gutter 8.

A water retention particle layer 10 is formed on the inner surface of the unit ceiling panel 1 and / or the outer surface of each flange 1b and / or the outer surface of the gutter 8 by spraying or the like. The water retention particle layer 10 is formed by spraying and bonding a mineral material such as silica sand to the surfaces of the unit ceiling panel 1 and the gutter 8. Note that the water retention particle layer 10 is not provided on the lower end surface of each inward flange 1b in order to promote the drop of water droplets.

The water-retaining particle layer 10 keeps dew condensation on the ceiling panel 1 and the flange 1b and suppresses falling, and the gutter 8 cooperates with the water-retaining particle layer 10 to effectively prevent water drops from falling.

The water droplets due to the condensation travel along the inner surface of the arch of the unit ceiling panel 1, ie, sew between the water retention particles, reach the inward flange 1b, flow down the outer surface of the flange, and flow downward. 1b, 1b falls into the gutter 8 from the lower end face of the butted portion. Some of the water droplets flow along the arched inner surface of the unit ceiling panel 1 toward the left and right ends in the frontage direction, and flow down along the side panel 2.

Both ends of the gutter 8 are opened at positions close to the side panel to form a water droplet outlet 11. Although not shown, a drainage channel (not shown) for guiding collected water droplets to the floor of the curing room can be provided at the left and right ends of the gutter 8.

In this manner, most of the water droplets transmitted from the inner surface of the unit ceiling panel 1 to the flange 1b are dropped into the gutter 8 and collected, and are guided to both ends of the gutter 8 to guide the side panel 2
The water can be drained out of the room through a drainage channel formed at the corner of the floor.

As a result, it is possible to obviate the problem that water drops fall from the inward flange 1b for bonding of the unit ceiling panel 1 onto the uncured concrete product being cured and form water drops.

[0022]

As described above, the inward flange is provided at the edge portion of the unit ceiling panel, and the plurality of unit ceiling panels are mutually bolted by abutting the inward flanges to form a ceiling panel. In a room, water drops due to dew condensation falling along the inward flange are reliably collected by a gutter attached to the flange, and the water drops fall on an uncured concrete product being cured to form a water drop drop mark. And can produce high quality concrete products.

Further, by forming the unit ceiling panel into an arch shape or providing a water-retaining particle layer on the inner surface of the panel or the outer surface of the gutter or flange, the effect of preventing water drops from falling can be further improved in cooperation with the gutter.
