Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a fireproof structure of a unit type building, and particularly, it can be used for a unit type building having a plurality of floors.

[0002]

[Background Art] Conventionally, a unit construction method that is often used for building a building such as a house is that a plurality of box-shaped building units are produced in advance in a factory, and these building units are horizontally or vertically oriented at a construction site. A unit type building is constructed by stacking and interconnecting them.

As shown in FIG. 8, a building unit 80 is manufactured at a factory by mounting an interior material such as a ceiling material and a floor material and an exterior material such as an outer wall material to a substantially rectangular frame 81 made of steel. The frame 81 includes pillars 82 erected at four corners, upper beams 83A and 83B bridged between the upper ends of these pillars 82, and each pillar.
It is configured to include lower beams 84A and 84B spanning between lower ends of 82.

When arranging such building units 80 in the horizontal direction at the construction site, the dimensions of the frame 81 of each building unit 80 and a predetermined dimension are ensured in order to secure a working space for interconnection. It is arranged to be separated. Therefore, as shown in the figure, four building units 80A
When ~ 80D is arranged so that the pillars 82 are arranged at each corner, the space between the building units 80 is a substantially cruciform plane surrounded by the pillars 82 and continuously extending in the vertical direction. 85 is formed.

By the way, in constructing a building, 3
For buildings with more than one story, facilities such as hotels and hospitals, or buildings constructed in designated fireproof areas, it is required to have a fireproof structure such as covering the frame of the building with plate-like fireproof material, If the unit building is required to be fireproof, the frame 81 of each building unit 80
Must be coated with a plate refractory material.

Each of the columns 82 forming the above-mentioned gap space 85 has the same side surface (side surface facing the building living room side of each frame 81) at the construction site in order to save waste of the plate-shaped refractory material. Then, it is covered with a large plate-shaped refractory material. Therefore, the gap space 85 is a cylindrical space that is surrounded by these plate-like refractory materials and that is continuous in the up-down direction and has a substantially planar cross shape, and has upper and lower end surfaces opened.

[0007]

However, this gap space 85 plays a role as a chimney when the plate-like refractory material is damaged and the flame penetrates into the interior when a fire occurs in the unit type building. There is a risk that fire will spread to the building units on the upper floors as fire spreads to other interstitial spaces.

For this reason, a fire-resistant structure of pillars in a building unit building in which a partition plate for partitioning the vertical space for each building unit is arranged in the vertical space (gap space 85) formed by the fire-resistant covering material and the pillars. Has been proposed (Japanese Patent Laid-Open No. 63-165631).
issue).

Specifically, by providing a partition plate on the upper end surface of each pillar 82 to cover the upper end surface, the clearance space is formed.
It is intended to block the flame in 85 in the vertical direction. However, according to this conventional example, since the vertical space (gap space 85) is blocked only by the partition plate, there is a problem that the fire resistance remains uncertain when the partition plate is exposed to the flame.

An object of the present invention is to provide a fireproof structure for a unit-type building which can obtain reliable fireproofness.

[0011]

According to a first aspect of the present invention, columns of a plurality of building units that are horizontally adjacent to each other through a predetermined gap space to form a unit-type building are bundled with the columns. A plate-shaped refractory material to be covered is additionally provided, and the refractory material is sandwiched in the gap space at a position overlapping the vertical end portion of the plate-shaped refractory material.

Here, as the plate-shaped refractory material, a calcium silicate plate or the like which has been conventionally adopted as a refractory material can be used, and it can be attached to a pillar by using steel nails, a fire-resistant adhesive or the like or a predetermined bracket or the like. Good. Further, as the refractory material sandwiched in the interstitial space, the block-shaped calcium silicate, soft refractory material, or the like can be used, and its natural width dimension is set to be slightly larger than the width dimension of the interstitial space. You can leave it.

As the soft refractory material, for example, rock wool, ceramic fiber, non-woven fabric, flex guard (trade name, manufactured by Nichias Co., Ltd.), which is a composite material in which turtle wire mesh is laminated, can be used.

The refractory material such as these may be pressed into the gap space after arranging a plurality of building units at a construction site, or in a factory, the pillars facing the pillars of other building units may be installed in advance. It may be attached to the side surface with steel nails or a fire resistant adhesive. Even if the natural thickness dimension of such a soft refractory material is smaller than the width dimension of the gap space, a predetermined natural thickness dimension may be obtained by stacking or bending a plurality of sheets.

According to a second aspect of the present invention, the pillars of a plurality of building units that are horizontally adjacent to each other through a predetermined gap space to form a unit type building collectively cover the pillars. A refractory material is additionally provided, and a planar blocking member of the clearance space is horizontally disposed at a position overlapping the vertical end of the plate-shaped refractory material in the clearance space, and a fireproof material is provided on the blocking member. It is characterized by being filled with a material filler.

Here, as the blocking member, for example, when four building units are arranged so that their corners are gathered, they may be formed in a substantially cross shape in a plane. Then, this blocking member may be arranged horizontally by previously providing a claw portion or the like on the outer surface of each pillar. Further, the blocking member may have a rising portion connected to the tip end portion extending between the columns so that the refractory filler does not flow out.

The refractory material of the first invention or the blocking member of the second invention may be provided at a position overlapping one or both of the upper and lower ends of the plate-like refractory material in the vertical direction.

[0018]

In the present invention as described above, since the refractory material or the blocking member is provided at a position overlapping the vertical end portion of the plate-shaped refractory material, the flame that has penetrated into the clearance space does not spread upward. It can be prevented, and it will not spread to the upper floors.

In this case, according to the first aspect of the present invention, the refractory material is press-fitted between the pillars and closely adheres to the side surfaces of the pillars, so that it is possible to reliably prevent the flame from spreading upward. Further, in the second aspect of the present invention, the refractory filling material filled above the blocking member is in close contact with the side surface of each column, and it is possible to reliably prevent the flame from spreading upward. Therefore, it is possible to obtain reliable fire resistance in the unit type building, and the above-mentioned objects are achieved by these.
