Abstract

PURPOSE:To enable the whole body of a building to be composed to be well balanced by connecting the upper and lower ends of an intermediate column to be set on the side surface of a vestibule unit, respectively to beams with pins, and by setting a ratio of the size of an opening section to the width of the side surface to a specified value or more. CONSTITUTION:Both the upper and lower ends of an intermediate column 15 to be set on the side surface of a vestibule unit 10 are jointed respectively to an upper beam 18 and a lower beam 20 with pins. In this case, the intermediate column 15 is set so that the dimension of an opening section is about 1/2 the width dimension of the side surface of the unit 10 or more. Accordingly, the rigidity of the unit 10 is made less than that of a general building unit, and so even when a unit type building is composed together with the general building unit, a force can be prevented from being concentrated on the unit 10. Accordingly, it is no longer required that the general building unit is reinforced and that any change be made to the material of columns 11-14 and beams 17-20.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a building unit which constitutes a unit type building, and is particularly applicable to an entrance unit which constitutes an entrance.

[0002]

BACKGROUND ART In a unit type building, as shown in FIG. 7, usually, a plurality of box-shaped building units 1 are combined by connecting upper and lower ends of four columns 2 with an upper beam 3 and a lower beam 4. It is composed of However, for example, as a unit that constitutes the entrance of a building, as shown in FIG. 8, a lower beam 4 on one side is formed to be shorter than its side dimension, and one of two pillars 2 on that side is formed. The building unit 90 connected to only the lower ends of the pillars 2 and having a lower beam between the pillars 2 as an opening part was sometimes used.

[0003]

In such a building unit 90, since there is no part of the lower beam on the side surface where the opening is provided, the rigidity is lowered, and the upper beam 3 hangs down due to the vertical load. There was fear. Further, when an outer wall panel is provided on the side surface provided with the opening portion so as to match the lower beam 4, the upper and lower sides of the panel are supported by the upper beam 3 and the lower beam 4, and one side surface is supported by the pillar 2. Since there is no support material on the other side surface of the panel, when a force is applied to the panel due to strong wind or the like, there may be a problem that a portion without the support material is pushed and deformed.

Therefore, the applicant of the present invention, as shown in FIG. 9, has an intermediate column 9 between the end of the lower beam 4 and the upper beam 3 of the opening.
A building unit 95 was created by attaching 1 to prevent hanging of the upper beam 3 and supporting the outer wall panel.

By the way, the building units 1 and 90 shown in FIGS. 7 and 8 usually use a pillar 2 and beams 3 and 4 of the same material and size for productivity and cost reduction.
And the beams 3 and 4 are rigidly joined together, and the building unit 95 shown in FIG. 9 is also constructed by rigidly joining the same columns 2, beams 3 and 4 as the building units 1 and 90, and intermediate columns. 91 was also rigidly joined to the beams 3 and 4, respectively.

If such building units 1 are installed on the foundation via anchor bolts respectively, and the rigidity is K = 1 when the displacement P is given by applying a force P to the upper part, the building unit 95 The rigidity of the building unit 1 changes in the range of K = 1.5 to 2 according to the position of the intermediate column 91.
Will be larger than. Therefore, when the unit type building 100 is configured using the building units 1 and 95 as shown in FIG. 10, only the building unit 95 at the entrance has a higher rigidity than the other building units 1, so that the building 100 is The applied force concentrates on the building unit 95, which causes a structural problem. Therefore, the other building unit 1 is reinforced to improve the rigidity to the same extent as the building unit 95, or the pillars 2, beams 3 and 4 of the building unit 95 are different from those of the building unit 1 in size and the like. However, the rigidity of the building units 1 and 95 must be reduced to the same level as that of the building unit 1, and in any case, the assembly of the building units 1 and 95 becomes complicated, resulting in poor productivity. Further, when the intermediate column 91 is rigidly joined, there is a problem that the structure of the joined portion becomes complicated and the joining work becomes complicated. In particular, when the intermediate column 91 is provided close to the column 2 and the intermediate column 91 is rigidly joined by welding, there is a problem that the column 2 becomes an obstacle and the workability is deteriorated.

An object of the present invention is to prevent the occurrence of structural problems as a whole building when a building is constructed by combining it with a general building unit even if it is provided with an opening portion. An object of the present invention is to provide a building unit that can improve workability without the need to reinforce the building unit or to use columns or beam members different from general building units.

[0008]

The building unit of the present invention is a building unit constituting a unit type building,
At least one side of the building unit has two columns,
An upper beam connecting between the upper ends of these columns, and an intermediate column disposed between two columns and having their upper ends pin-joined to the upper beam,
And a lower beam which is pin-joined to the lower end of the intermediate column and is joined to the lower ends of one of the two columns, the intermediate column being the width dimension of the opening portion without the lower beam. Is arranged so as to be approximately ½ or more of the width dimension of the side surface of the unit on which the intermediate column is provided.

[0009]

In the building unit of the present invention as described above,
The upper and lower ends of the intermediate column are pin-bonded to the upper beam and the lower beam, respectively, and the intermediate column is arranged so that the width dimension of the opening without the lower beam is approximately 1/2 or more of the width dimension of the unit side surface. Therefore, the rigidity of the building unit is about 1/2 to 1 when the rigidity of a general building unit is 1.
That is, since it is smaller than a general building unit, even when a unit type building is configured with a general building unit, the force is not concentrated only on the building unit of the present invention, and the structure of the entire unit type building is balanced. It can be good. That is, if the rigidity of this building unit is 1 or less, the force applied to the building will be applied to other building units according to the ratio of the decrease, but since the building unit of the present invention is used for the entrance, etc. In general, only one or two building units are used in a box, but many general box-shaped building units are used. Therefore, the force applied to the building is distributed to these building units and concentrated in one building unit. Will not be added. Therefore, it is not necessary to configure the building unit of the present invention with columns and beams different from general building units, and it is not necessary to increase the types of members such as columns and beams, so productivity is improved and cost is also reduced. To do. Further, since it is not necessary to reinforce other general building units, productivity is further improved and manufacturing cost is further reduced.

Further, since the intermediate column is pin-joined to each beam, the structure of the joined portion is simplified and the joining work is facilitated. Even when the intermediate column is provided close to the column 2, workability is improved. Is never reduced.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to the drawings. FIG. 1 shows an entrance unit 10 which is an example of a building unit of the present invention. Entrance unit 1
0 has four pillars 11 to 14 at its corners, and an intermediate pillar 15 is provided on the side surface in the short side direction.

Between the upper ends of the pillars 11 to 14, the long side upper beam 17,
The short-side upper beam 18 is laid across the columns 11, 13 and between the columns 1 and 13.
A long-side lower beam 19 is bridged between 2 and 14. Further, between the pillars 13 and 14, and between the pillar 11 and the intermediate pillar 15
Short-side lower beams 20 are bridged between them. A plurality of small beams, joists and the like parallel to the short-side beams 18 and 20 are provided between the long-side upper beams 17 and the long-side lower beams 19 as needed, and the ceiling portion has a ceiling (not shown). Braces are provided diagonally.

In FIG. 2, each pillar 11 to 11 of the entrance unit 10 is shown.
15, a schematic diagram of a method of joining the beams 17 to 20 is shown. In addition, in FIG. 2, the joint portions indicated by circles are the portions that are pin-joined, and the other joint portions are the portions that are rigidly joined. Also, the part indicated by the triangle mark shows the joint part by the anchor bolt,
The joining of the anchor bolt is regarded as a pin joining because it is deformed when a force is applied.

As shown in FIG. 2, the joint between the upper end of the intermediate column 15 and the upper beam 18 on the short side of the entrance unit 10 and the joint between the lower end of the intermediate column 15 and the lower beam 20 on the short side are respectively pinned. The columns 11 to 14 and the beams 17 to 20 are rigidly joined. That is, as shown in FIG. 3, the upper end of the intermediate column 15 is bolted to the flange of the upper beam 18 on the short side composed of a channel material having a U-shaped cross section to form a pin joint. Further, the lower end of the intermediate column 15 is pin-joined by bolting a short side lower beam 20 composed of a channel material having a U-shaped cross section to a bracket 22 standing upright from the intermediate column 15. In addition, as shown in FIG. 2, in the intermediate column 15, the width dimension of the lower beam 20 joined to the intermediate column 15 is about ¼ of the width dimension of the side surface on the short side of the entrance unit 10, That is, the width of the opening is about 3/4.

The entrance unit 10 having such a structure is combined with a general building unit 1 like the conventional unit type building 100 shown in FIG. 10 to form a unit type building. At this time, the upper and lower ends of the intermediate column 15 are joined by pins, and the width dimension of the opening portion is about 3/4 of the width dimension of the side surface on the short side of the unit 10, that is, 1/2 or more. The rigidity is 1/2 to 1 as compared with the general building unit 1. Therefore, when a unit-type building is configured to include the entrance unit 10, since the rigidity of the entrance unit 10 is smaller than that of the other building units 1, even if a force is applied to the building due to wind pressure or the like, only the entrance unit 10 has a force. It is distributed to each building unit 1 without being concentrated.

According to this embodiment, since the upper and lower ends of the intermediate pillar 15 of the entrance unit 10 are joined by pins, the rigidity of the entrance unit 10 when it is formed of the same pillars and beams as the building unit 1 is improved. 1/2 to 1 of building unit 1
It can be made smaller and smaller than the building unit 1. Therefore, even if a force is applied to a unit-type building composed of the entrance unit 10 and the building unit 1, the force is not concentrated only on the entrance unit 10 but is distributed to each building unit 1, so that the structural balance is achieved. A good and strong unit type building can be constructed.

Further, since the rigidity of the entrance unit 10 does not become larger than that of the other building units 1 as in the conventional case,
The building unit 1 is reinforced to increase its rigidity, or the pillars 11 to 15 and the beams 17 to 20 of the entrance unit 10 are configured with those having different dimensions and the like from the other building units 1 to create the entrance unit 1.
It is not necessary to match the rigidity of 0 with the building unit 1. For this reason, the work of manufacturing the entrance unit 10 and the building unit 1 can be facilitated and the productivity can be improved, and the types of parts can be reduced and the production cost can be reduced.

Further, the upper end of the intermediate column 15 has an upper beam 18 on the short side.
The lower end is joined to the end of the short-side lower beam 20, but since each of these joints is a pin joint, it can be easily joined by bolts or the like, and compared with the case where the intermediate column 15 is rigidly joined. As a result, the joining structure and joining work can be simplified, and productivity can be improved and costs can be reduced. In particular, the intermediate pillar 15
Since it is arranged near the column 11, workability can be significantly improved in this embodiment, which can be easily joined by bolts or the like, as compared with the case of rigid joining by welding or the like.

Further, since the intermediate column 15 is provided, even if a vertical load is applied to the short-side upper beam 18, the intermediate column 15 is provided.
It is possible to prevent the upper beam 18 from hanging down by being supported by.
Furthermore, since the intermediate pillar 15 serves as a support material for the outer wall panel,
The outer wall panel can be easily attached, and even if a force is applied to the outer wall panel due to strong wind or the like, the force can be supported by the intermediate column 15, so that the outer wall panel can be prevented from being deformed or dropped.
