Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a unit-type building and a method for constructing the unit-type building, and can be used for a building requiring a large internal space such as a restaurant or a store.

[0002]

BACKGROUND ART Conventionally, a pillar of a building unit that constitutes a unit-type building is set as a detachable temporary pillar, and when the plurality of building units are combined at a construction site, the temporary pillar is removed from each building unit. , It is known to form a large space without pillars in multiple building units. And as a method of forming such a space,
Some are described in Japanese Examined Patent Publication No. 54-2492. According to this, the building unit is configured to include a floor board, a ceiling board, and a plurality of pillars connecting the floor board and the ceiling board, and at least one of these pillars is a detachable temporary pillar, Further, a reinforcing member is embedded inside the floor board. Then, when a plurality of such building units are installed side by side so that the temporary columns are adjacent to each other and the reinforcing members of each floor member are connected to each other, each floor plate is reinforced by the connected reinforcing member. Even if the temporary columns are removed from the building units, the strength of those building units will be secured. However, in such a case, since the reinforcing material is integrated with the floorboard, the structure of each floorboard is different between the building unit in which the temporary columns are erected and the normal building unit in which the temporary columns are not used. . Therefore, in order to produce the building unit, two types of floor boards have to be prepared, which causes a problem of low productivity efficiency.

Therefore, the applicant of the present application has filed Japanese Patent Application Laid-Open No. 4-136.
The method described in Japanese Patent No. 341 has been proposed. According to this, a building unit is configured to include columns that are erected at four corners and four upper and lower beams that are bridged between the upper ends and lower ends of these columns, At least one of these is a detachable temporary pillar. Then, after a plurality of such building units are installed side by side so that the temporary columns are adjacent to each other, the temporary columns are removed from each building unit.
At this time, in order to secure the strength of each building unit, a reinforcing frame (reinforcing beam) straddling the building units is retrofitted and bridged between the remaining columns. In such a case, since a reinforcing frame for reinforcing the building unit is prepared separately, the columns and beams are shared between the building unit where the temporary columns are erected and the normal building unit where they are not erected. Yes, the above problems are solved.

[0004]

However, in the latter, since the reinforcing frame is attached so as to traverse the inside of each building unit, it has been an obstacle in designing the floor plan. For this reason, there is a limit to the free floor plan design, even though the interior is a large space without pillars.

An object of the present invention is to provide a unit type building and a method of constructing the unit type building, which can improve the degree of freedom in the floor plan design of an internal space formed by a plurality of building units.

In this embodiment as described above, a wide space without obstacles is formed inside the first-floor building units 12E to 12L as follows. First, in a factory, the first-floor building units 12E to 12L are bridged between four pillars 16 that are erected at four corners and the upper ends of these four pillars 16 to form an upper plane quadrangle in the rectangular parallelepiped. Four upper beams 17 and four lower beams 18 bridged between the lower ends
And the connection fittings 19 and 19A for connecting these pillars and beams, and one or two of the four pillars 16 is set as a detachable temporary pillar 16A, and the building unit is constructed at the construction site. 12E to 12L are assembled by assembling the corner portions 20 on which the temporary columns 16A are erected, and then the gathered corner portions 20 are joined together to form a cross-section connecting member 2 having a cruciform cross section.
Then, the temporary columns 16A are removed from the corners 20 to form wide spaces without obstacles in the building units 12E to 12L.

According to this embodiment, the following effects can be obtained. That is, the first-floor building unit 12E-
In 12L, the four corners 2 on which the temporary pillars 16A are erected
The connection member 19A having a number 0 is a connecting member 2 having a cross-shaped plane cross section.
Since they are connected to each other at 9, the eight upper beams 17 forming each corner portion 20 can be regarded as one large cross beam. Therefore, even if the temporary pillars 16A are removed from the respective corner portions 2, the building units 12E to 12L are constructed with the large beams.
Since the strength is secured, the conventional reinforcing frame can be eliminated, and a large space without obstacles can be formed inside the building units 12E to 12L. Therefore,
The degree of freedom in floor plan design can be improved.

In addition, the building unit 12E gathered together

The strength of E to 12 L can be further improved.

Further, since the reinforcing beams 14L and 14M and the reinforcing beams 14H to 14L intersect and are connected to each other at positions apart from the corners 20, the reinforcing beams 14 where vertical loads are most concentrated are intersected. Since the position is away from each corner portion 20, even when the second-floor building units 13 are installed side by side, it is possible to prevent the vertical load from being transmitted to the corner portion 20 where the pillar is not erected, and thus the connecting member. It is possible to reliably ensure the durability of the parts connected by 29.

Further, since each corner portion 20 is formed of the fitting 19A for connecting the ends of the upper beam 17, the temporary column 1
Since the bolt hole 22A for attaching 6A, the bolt hole 24A for attaching the connecting member 29, and the like may be provided in the fitting 19A, such bolt holes 22A and 24A are long and large in weight. The work is easier than the direct installation on the end of the upper beam 17, and the building units can be efficiently produced.

Further, since the connecting member 29 only needs to be formed by joining two metal plates 29A having the same shape, the connecting member can be easily manufactured.

Further, by arranging the unit type buildings 12E to 12L side by side according to the procedure described above, the building unit 12E
It is possible to form a large space without obstacles in the interior of ~ 12L.

It should be noted that the present invention is not limited to the above-described embodiment, but includes other configurations capable of achieving the object of the present invention, and the following modifications are also included in the present invention.
For example, in the above-mentioned embodiment, the corner portion 20 is the fitting 19
Although it is formed by A, the corner portion according to the present invention may be formed, for example, by connecting two upper beams at right angles to each other and directly connecting them, and it is not always necessary to use a joint fitting. Good. However, it is preferable to use the fitting to obtain the above-mentioned effects.

Further, in the above-mentioned embodiment, the reinforcing beam 14 is arranged between the first-floor building unit 12 and the second-floor building unit 13, but the reinforcing beam 14 is not always necessary for the present invention. Even when the second-floor building unit 13 is directly placed on the upper part of the second-floor building unit 12, it is included in the present invention.

In the above embodiment, the eight first-floor building units 12E to 12L form a wide space without any obstacles therein, but the number is not particularly limited to eight, and at least four. One building unit should be put together. Further, the building units in this case are not limited to those arranged in parallel on the first floor, but may be, for example, those arranged on the second floor or above it.

[0027]

As described above, according to the present invention, since the four corners on which the temporary columns are erected are connected to each other by the connecting members having a cross-shaped cross section, each corner is formed. A total of eight upper beams can be regarded as a large cross-shaped beam,
Therefore, even if the temporary pillar is removed from each corner, the strength of each building unit is secured by this large beam, so that the conventional reinforcing frame is unnecessary, and there is no obstacle inside each building unit. There is an effect that a space can be formed and the degree of freedom in floor plan design can be improved.
