BACKGROUND OF THE INVENTION
The present invention relates to a unit-type building in which a plurality of factory-produced building units are stacked and built at a construction site, for example, a three-story unit-type building.
[0002]
[Background]
2. Description of the Related Art Conventionally, a unit type building is known in which a plurality of box-shaped building units produced in a factory are combined in a horizontal direction and a vertical direction on a foundation of a construction site.
In such a unit-type building, a three-story house is also commonly used for narrow spaces in urban areas in order to secure a sufficient floor area in a narrow site (see, for example, JP-A-9-60312). ). Therefore, the building unit constituting the unit type building is also designed on the assumption of a three-story building.
[0003]
In addition, since it is difficult to provide a large garden in such a small-sized building, the garden may be formed using the roof of the building, or a walking space may be formed according to various purposes. .
[0004]
[Problems to be solved by the invention]
However, since the building is more swayed toward the upper floor side, if the roof is provided so that it can be walked, the sway may be felt when walking on the roof, and the resident may have anxiety. For this reason, the individual building units are reinforced to improve the rigidity of the entire building. However, if all the building units are reinforced easily, the number of reinforced parts increases and the productivity of the building units deteriorates. There is a problem that the merit as an industrialized house is impaired.
[0005]
An object of the present invention is to provide a unit type building that can efficiently reinforce the building and reduce shaking on the upper floor side.
[0006]
[Means for Solving the Problems]
If the unit type building of this invention is demonstrated using the code | symbol in embodiment mentioned later, the unit type building built by stacking several building units (10,20,30) produced in the factory on a construction site (1) In each floor, the building unit including a main frame (40) and a sub frame (50) for reinforcing the main frame is arranged, and the main frame is arranged at four corners. A column (41), four ceiling beams (42), (43) spanned between the top ends of the columns, and four floor beams 44 spanned between the bottom ends of the columns), (45), and the sub-frame includes the pillars constituting the main frame, and intermediate pillars (51) erected between the ceiling beam and the floor beam, and the same vertical plane continuous across the floors. Within (100, 200, 300 Corner at 400) (A, B, and is characterized in that C, D), and is provided on a vertical substantially straight line.
[0007]
In the present invention, the building unit on each floor constituting the unit type building is reinforced by providing a subframe. At this time, since the subframe is provided in the same vertical plane continuous over each floor, the entire vertical plane is provided. Acts as a rigid construction surface, and the shaking on the upper floor side of the building is suppressed. In addition, by providing the subframe limited to the same vertical plane, a highly rigid construction surface is reliably formed, so that the building can be reinforced efficiently, eliminating unnecessary reinforcement and improving the productivity of the building unit. Can be maintained.
In addition, since the reinforcing parts are continuous in the vertical direction, a highly rigid construction surface is more reliably formed, and the installation positions of the subframes are the same in the upper and lower building units. Will improve.
[0008]
Further, in such a unit type building, it is desirable that the sub-frames on each floor in the same vertical plane are provided on a substantially vertical straight line.
In such a case, since the reinforced portion is continuous in the vertical direction, a highly rigid construction surface is formed more practically, and in the upper and lower building units, the installation positions of the subframes are the same. Increases productivity of building units.
[0009]
Furthermore, in the unit type building of the present invention, the sub-frame is provided on a substantially straight line in the same vertical plane continuous over the floors, and a plurality of rows of sub-frames on each floor on the straight line are provided. It is preferable that the sub-frames on the same vertical plane and on the same floor are provided in different building units arranged in the horizontal direction.
In such a case, by providing a plurality of subframes on each floor on a substantially vertical straight line, the rigidity as the composition surface is further increased, and in the same vertical plane, one building unit has a plurality of buildings. Since it is not reinforced by the subframe, there is no fear that a part in the vertical plane is locally reinforced, and the rigidity balance is improved.
[0011]
At this time, if the sub-frames of each floor on the straight line are respectively provided on a pair of vertical surfaces forming the corner, the corner is further reinforced.
[0012]
In addition, if the sub-frames of each floor on the straight line are respectively provided on a pair of vertical surfaces forming all corners, all the vertical surfaces formed in the building will have a highly rigid construction surface. The whole is reinforced more powerfully.
[0013]
On the other hand, in the unit type building of the present invention, the subframe includes a ceiling beam (42, 43) and a stud (51) standing between floor beams (44, 45) constituting the building unit, and the ceiling A reinforcing member (61) may be provided at each joint portion of the beam and the floor beam with the stud.
In such a case, each joint portion between the ceiling beam and the floor beam between the pillars is reinforced by the reinforcing member, so that deformation or the like of the joint portion is prevented, and the resistance strength of the building unit against shaking can be increased.
[0014]
Further, in the unit type building of the present invention, the subframe is erected between the ceiling beam and the floor beam of the channel material constituting the building unit, and the opening side in the channel material is provided on the ceiling beam and the floor beam. A beam cover (62) for closing may be provided over substantially the entire length of the ceiling beam and floor beam.
In such a case, the ceiling beam and the floor beam are reinforced by the beam cover, so that bending of the beam, lateral buckling, and the like are prevented, and the resistance strength of the building unit against shaking is also increased.
[0015]

[0020]
That is, the sub-frame 50 on the first vertical surface 100 side is constructed between the intermediate column 51 erected between the upper and lower long-side ceiling beams 42 and the long-side floor beam 44 and between the intermediate column 51 and the column 41 at the corner A. Upper and lower horizontal members 52, a large diagonal member 53 disposed on a diagonal line within a region surrounded by these, two small diagonal members 54 disposed on another diagonal line, and each small diagonal member It consists of two connecting plates 55 that connect the material 54 and the large diagonal material 53 at the center. However, the configuration of the sub-frame 50 is not limited to this, and for example, the large diagonal material 53 and each small diagonal material 54 may be replaced with braces.
[0021]
On the other hand, the sub-frame 50 on the third vertical plane 300 side also has the same configuration as the sub-frame 50 described above except that the stud 51 is erected between the upper and lower short-side ceiling beams 43 and the short-side floor beams 45. is there.
[0022]
In addition, if the floor beams 44 and 45 are described as representatives at positions corresponding to the joint portions of the beams 42 to 45 with both ends of the studs 51, as shown in FIGS. Two stiffeners (reinforcing members) 61 abutting against the flanges 46 and 47 and the web 48 are fixed by welding or the like.
[0023]
Further, a beam cover 62 made of a slightly smaller channel material is welded to the floor beams 44 and 46 over substantially the entire length of the floor beams 44 and 46 so as to close the opening side. Although not shown, such a beam cover 62 is also provided on each of the ceiling beams 42 and 44 to which the upper ends of the studs 51 are joined. And the code | symbol 49 in FIG. 4 is a wall panel made from ALC (autoclaved lightweight lightweight concrete).
[0024]
If the building units 10, 20, and 30 described above are stacked in the vertical direction so as to correspond to the corner A, as shown in FIG. 1, there is a vertical straight line near the corner A of the first vertical surface 100. The subframe 50 is provided in the above. Similarly, in the vicinity of the corner A of the third vertical surface 300, the subframe 50 is provided on a vertical straight line.
[0025]
Furthermore, since the building units 10, 20, and 30 arranged in the other corners B to D also have a pair of subframes 50 in the same manner, The frame 50 is provided on a vertical straight line, and further, in the vicinity of the corners C and D of the second vertical surface 200, in the vicinity of the corner D of the third vertical surface 300, and in each corner B of the fourth vertical surface 400, Even in the vicinity of C, the subframe 50 is provided on a vertical straight line. That is, the unit type building 1 is reinforced by providing the sub-frame 50 on a vertical straight line so as to sandwich the corners A to D at all the corners A to D.
[0026]
By the way, in this embodiment, among the building units 10, 20, and 30 that form the second and fourth vertical surfaces 200 and 400, the building units 10A, 20A, and 30A that do not face the corners A to D are also subframed. 50 is provided. The subframe 50 is the same as the subframe 50 on the short side shown in FIG. Therefore, in the second and fourth vertical planes 200 and 400, three rows of the subframes 50 on a straight line are provided.
[0027]
Moreover, in the unit type building 1 which combines each building unit 10,20,30 as mentioned above, each sub-frame 50 in the same vertical plane 100,200,300,400 and on the same floor is each horizontal direction. Are provided in different building units 10, 20, 30.
[0028]
In this embodiment, as in a normal unit building, each building unit 10, 20, 30 is produced at the factory and then transported to the construction site. The building unit 10 is disposed, and the second-floor building unit 20 and the third-floor building unit 30 are sequentially stacked on the upper part.
Moreover, when the land roof 70 is comprised with a some roof unit, those roof units are stacked on each three-story building unit 30, and the unit type building 1 is built.
[0029]
According to this embodiment, there are the following effects.
1) The building units 10, 20, and 30 on each floor constituting the unit type building 1 are reinforced by providing the subframe 50. At this time, the subframe 50 is continuous over each floor, for example, the first vertical plane Since it is provided in 100, the entire first vertical surface 100 can be made to act as a rigid construction surface, and shaking on the upper floor side of the building 1 can be suppressed. Therefore, even if the building 1 is a three-story building, there is no worry of shaking when walking on the rooftop.
[0030]
2) Since the subframes 50 of each floor are provided not only in the first vertical plane 100 but also in all other vertical planes 200, 300, 400, the rigidity of the entire building 1 can be greatly increased. , Shaking can be surely suppressed.
[0031]
3) Since the subframe 50 is provided only in the vertical planes 100, 200, 300, and 400, a highly rigid construction surface is reliably formed. For example, the subframe 50 is set at the center of the building 1. The building 1 can be efficiently reinforced without having to be provided on the inner side. Therefore, it is possible to satisfactorily maintain the productivity of the building units 10, 20, and 30 without unnecessary reinforcement.
[0032]
4) Since the sub-frames 50 on each floor in the vertical planes 100, 200, 300, and 400 are provided on a vertical straight line, they can be continuously reinforced in the vertical direction, and a more rigid structural surface is formed more realistically. it can. Moreover, since the installation position of the sub-frame 50 is the same in the upper and lower building units 10, 20, and 30, the productivity of each building unit 10, 20, and 30 can be improved.
[0033]
5) Of the subframes 50 on each floor in the vertical plane 100, 200, 300, 400, each subframe 50 on the same floor is provided in a different building unit 10, 20, 30 arranged in the horizontal direction. Therefore, one building unit 10, 20, 30 is not reinforced by the plurality of subframes 50. For this reason, there is no fear that a part in the vertical surfaces 100, 200, 300, and 400 is locally reinforced, and the rigidity balance can be improved.
[0034]
6) Since the subframes 50 of each floor on a straight line are provided close to the corners A to D of the building 1, the corners A to D of the building 1 can be reinforced in a vertical direction. That is, since the corners A to D having higher rigidity are further reinforced, the building 1 can be reinforced more efficiently and the shaking can be further reduced.
[0035]
7) At this time, the corners A to D can be reliably reinforced because the sub-frames 50 of the respective floors on the straight line are provided so as to sandwich the corners A to D from both sides.
[0036]
8) In addition, since all the corners A to D of the building 1 are reinforced, they are compared with the case where all the vertical planes 100, 200, 300, 400 are simply provided with the straight subframes 50. The rigidity of the vertical surfaces 100, 200, 300, and 400 can be greatly increased, and the entire building 1 can be reinforced more strongly.
[0037]
9) Since each joint portion between the column 51 of the sub-frame 50 and the ceiling beams 42 and 43 and the floor beams 44 and 45 is reinforced by the two stiffeners 61, the deformation of the joint portion can be prevented and the vibration can be prevented. The opposing strength of the building units 10, 20, and 30 can be increased.
[0038]
10) Since the ceiling beams 42 and 43 and the floor beams 44 and 45 to which the subframe 50 is joined are reinforced by the beam cover 62, the beams 42 to 45 can be prevented from being bent or laterally buckled. The resistance strength of the building units 10, 20, 30 against shaking can be increased.
[0039]
In addition, this invention is not limited to the said embodiment, Including other structures etc. which can achieve the objective of this invention, the deformation | transformation etc. which are shown below are also contained in this invention.
For example, in the above-described embodiment, the subframe 50 is provided on each of the vertical surfaces 100, 200, 300, and 400. However, any one of them, two, or three vertical surfaces are provided. It is included in the present invention even if it is done.
[0040]
The sub-frame 50 which is on the vertical straight line any one corner A~D or two, or may be provided in the three corners.
[0042]
Further, in the same vertical plane 100, 200, 300, 400, the number of columns of the subframes 50 on a vertical straight line is arbitrary, and the number of columns is not necessarily plural.
[0044]
【The invention's effect】
As described above, according to the present invention, the building unit on each floor constituting the unit type building is reinforced by providing the subframe, but at this time, the subframe is provided in the same vertical plane continuous over each floor. The entire vertical surface acts as a rigid construction surface, and can suppress shaking on the upper floor side of the building. In addition, by providing the subframe limited to the same vertical plane, a highly rigid construction surface is reliably formed, so that the building can be reinforced efficiently, eliminating unnecessary reinforcement and improving the productivity of the building unit. There is an effect that can be maintained.
