Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method of constructing a unit building provided with a refractory material.

[0002]

BACKGROUND ART Conventionally, as a fire resistant structure of a unit building, there has been proposed one in which an autoclave curing aerated concrete (ALC) panel is attached to a floor portion in a building unit which is an upper floor. In the manufacturing of building units, after installing fire-resistant ALC panels to the floor frame with square beams, pillars are attached to the four corners of this floor frame, and ceiling frames are attached to these pillars to assemble the unit frame. An outer wall panel, an inner wall panel, etc. are attached to this unit frame.

[0003]

In order to increase the manufacturing efficiency of building units in a factory, it is preferable that the unit frame being assembled is light. However, since the refractory ALC panel was attached to the floor frame from the early stage of the unit frame assembly process,
In the subsequent pillar mounting process and ceiling frame mounting process, the workability of the assembly was deteriorated due to its weight. Therefore, an object of the present invention is to provide a method of constructing a unit building that can improve the workability of assembling a unit frame in a factory.

[0004]

According to the method of constructing a unit building according to the present invention, after a building unit is manufactured in a factory, it is sandwiched between building units on upper and lower floors when building a building unit on site. It is characterized by attaching refractory material. Specifically, for example, prepare a fireproof material separate from the building units on the upper and lower floors, install the building unit on the lower floor at the construction site, and then install the fireproof material on the building unit on the lower floor. However, by installing the building unit on the upper floor on this fire resistant material, the fire resistant material can be attached between the building units on the upper and lower floors.

When the refractory material is mounted so as to be sandwiched between the building units on the upper and lower floors, the refractory material may be mounted on at least one of the building units on the upper and lower floors in advance. This refractory material may be attached to the building unit either at the factory or at the construction site.

Further, according to another construction method of the present invention, when manufacturing a building unit in a factory, after assembling the unit frames of the upper and lower building units, the floor side of the upper unit frame and the lower unit frame. A refractory material is attached to at least one of the ceiling sides of the. After attaching the refractory material to the unit frame, the building unit is manufactured by attaching outer wall panels, inner wall panels, etc. to the unit frame as usual.

Specifically, for example, in the factory, one piece of refractory material of a predetermined thickness is attached to the floor side of the upper unit frame or the lower unit frame ceiling side, or the floor of the upper unit frame. Side and lower side unit frame ceiling side shall be attached with fireproof material of half thickness of specified thickness. The refractory material includes an autoclave curing aerated concrete (ALC) panel, a fire resistant sheet,
Includes a calcareous board.

[0008]

According to the present invention, the refractory material is not attached to the floor frame during assembly of the unit frame in the factory, and the unit frame is assembled after the unit frame is assembled or after the building unit is manufactured. Alternatively, refractory materials will be attached to the building unit. Therefore, since the refractory material is not attached during the assembly of the unit frame, the weight is lighter than that during the conventional assembly of the unit frame, and as a result, the work of installing the pillars and the work of installing the ceiling frame are facilitated. Improves workability.
