2. Description of the Related Art As a fire hydrant box for housing hoses and nozzles for fire fighting, a box body made of a metal plate is generally used. And when installing this on the field wall that constitutes the fireproof compartment in the building, an opening for installation is provided in the field wall, a fire hydrant box is fitted into the opening, and the fire hydrant exposed on the side opposite to the fire hydrant box on the field wall. A method of closing the back surface of the box with a refractory material is generally used. Such a method must completely close the gap between the fire hydrant box and the boundary wall opening, which has been recognized as a complicated work in the past. To solve this, for example, in Japanese Utility Model Laid-Open No. 3-101972. The disclosed method has been proposed. As shown in FIG. 3 as a cross-sectional structure, this invention forms the entire fire hydrant box A with a refractory material in order to omit the troublesome closing work with the refractory material. The boundary wall is shown as B in the figure.

However, such a conventional fire hydrant box has a problem that the weight to be carried becomes extremely large because it is entirely made of a refractory material. Since an expansive silicon-based inorganic aggregate or a clay mineral material such as kaolin is used for this refractory material, if the entire fire hydrant box is made of such refractory material, its weight becomes extremely large. This deteriorates work efficiency due to its weight both in terms of transportation from the manufacturing plant to the construction site and handling of workers at the construction site, resulting in high cost.

Further, in the method other than the method disclosed in Japanese Utility Model Laid-Open No. 3-101972, after all, the conventional construction method has to be used, and the space between the fire hydrant box and the boundary wall is completely blocked by a fireproof material. Need to finish. Therefore, fireproof construction cannot be performed until after the fire hydrant box is installed, and the order of construction at the site is automatically determined, which reduces the degree of freedom in construction work.

SUMMARY OF THE INVENTION The present invention solves the above-mentioned problems and makes handling and installation of a fireproof panel attached to the back of a fire hydrant box extremely easy and convenient without increasing the weight as in the conventional case, and a fireproof compartment. A method for constructing a fire hydrant box that facilitates construction of a fire hydrant box on a boundary wall, and a fireproof panel for installing the fire hydrant box used for the method. Among the gist of the present invention, first, as a method of constructing a fire hydrant box, a step of installing the fire hydrant box in the opening provided in the fireproof partition wall, and a fire hydrant box on the back side of the fire hydrant box installed And a step of assembling and installing a plurality of refractory panels surrounding the projecting portion. Next, the fire hydrant panel for installing the fire hydrant box used in the above construction method is a fire proof panel that surrounds the back side of the fire hydrant box, and is based on a panel base material that is divided into a plurality of pieces corresponding to the vertical or horizontal direction of the fire hydrant box. A refractory material made of a material different from the material is attached, and a panel base material fixing means for phase-locking the panel base materials to each other is provided on the panel base material divided into the plurality of pieces.

[0006]

According to the construction method of the present invention, first, the fire hydrant box made of the same steel plate as the conventional one is fitted into the opening provided in the boundary wall of the fireproof compartment, and fixed to the aggregate or the like around the opening. Next, a plurality of fireproof panels are assembled on the rear side of the fire hydrant box surrounding the protruding portion of the fire hydrant box to completely cover the back surface of the fire hydrant box. Such a method intends to solve the problem of increased weight and complexity of construction work by using a conventional fire hydrant box as it is and combining it with a simple construction method of assembling the panel. Next, the fireproof panel for installing the fire hydrant box used in the above construction method is a fire resistant panel that surrounds the back side of the fire hydrant box, and the base material is a panel substrate divided into a plurality of parts corresponding to the vertical direction or the horizontal direction of the fire hydrant box. Since a refractory material made of a material different from the above is attached and the panel base material fixing means for phase-locking the panel base materials to each other is provided on the plurality of divided panel base materials, the weight of the divided panel unit is not so great. It does not become large, and it can be assembled with screws etc. This also leads to an increase in weight and a solution to the complexity of construction work.
