Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a structure for preventing deformation of a reinforcing beam and a unit-type building reinforced with a reinforcing beam having the structure for preventing deformation of a reinforcing beam.

[0002]

2. Description of the Related Art Conventionally, unit-type buildings constructed by combining a plurality of box-shaped building units manufactured in a factory at a building site have been used. As a building unit forming a unit type building, a building unit having a rectangular parallelepiped frame in which upper and lower ends of four corner columns are connected by ceiling beams and floor beams is generally used. When one living room is constructed by combining a plurality of such building units, the central portion is in a state where a plurality of pillars are combined, and a large space cannot be formed. For this reason,
A method has been adopted in which a large space is created using a unit in which some of the pillars of the building unit are omitted (hereinafter, referred to as a large space building unit). However, when this large space building unit is used, the rigidity of the building unit is reduced, and there is a possibility that the load of the building unit or the like placed above cannot be supported. In order to solve this, a reinforcing beam for two spans connecting the upper ends of the pillars arranged on both sides of the part where the part of the pillar is omitted may be provided as a center (Japanese Patent Application Laid-Open No. 8-277580). Reference).

[0003]

When reinforcing with such a reinforcing beam, the reinforcing beam receives a vertical force due to the load of a building unit placed above, etc. Curving may occur in the direction perpendicular to the axial direction of the reinforcing beam.

In order to avoid this problem, it is necessary to increase the thickness of the main body of the reinforcing beam, but the thickness is limited due to the provision of the reinforcing beam between the building units for large spaces. For this reason, a means for preventing the bending of the reinforcing beam main body without increasing the thickness of the main body is desired.

Also, the other large space building unit 1
21B (122B) is a large space building unit 121A.
Has the same configuration except that the temporary pillar 37 is a pillar 31 and one of the two pillars 31 located next to the temporary pillar 37 is omitted. That is, the two have a so-called unconventional shape. The normal building unit 121C forming the first floor and the normal building unit 122 forming the second floor
As for C, only points having all four pillars 31 at the four corners are shown in FIG.
Are different from the large space building unit 121A shown in FIG.

In FIG. 2, two large-space building units 121A and 121B, each indicated by a dashed-dotted line, are in a state where the respective pillar omitted corners are brought together to form the pillar omitted joint 20. They are arranged adjacently. Thus, the large space building unit 121A,

A metal shear plate 42 used for positioning A and 121B is attached to the reinforcing beam main body 41 at a substantially central position in the vertical direction along the longitudinal direction of the reinforcing beam main body 41. Here, the shear plate 42 is formed by bending two sides of a rectangular metal plate, and has two L-shaped cross sections orthogonal to each other. One side thereof is fixed to the reinforcing beam main body 41 by welding or the like, and the other side is similarly fixed to the stiffener 43.
As a result, the reinforcing beam main body 4 is

A plurality of metal nuts 52 are provided above the short side floor beams 33A of A and 122B so as to be arranged in a line along the longitudinal direction of the reinforcing beam main body 41. A metal deformation prevention bolt 51 which is a deformation prevention means is screwed to the nut 52,
The nut 52 and the deformation preventing bolt 51 constitute a reinforcing beam deformation preventing structure 50 (see FIGS. 5 and 9).
The distal ends of the deformation preventing bolts 51 are abutted against the reinforcing beam main body 41 from opposite sides thereof (see FIG. 9).

The reinforcing beam 40 thus configured, the short-side floor beams 33A of the large-scale building units 122A and 122B on the upper floor, and the large-space building units 121A and 12 on the lower floor.
The joining procedure with the short side ceiling beam 32A of 1B will be described. Large space building units 121A (122A), 121 at the factory

In order to prevent deformation of 1A (122A) and 121B (122B), temporary columns 3 are provided at corners where columns 31 are omitted.
7 are provided. The large-space building units 121A and 121B constituting the first floor are arranged adjacent to each other, and the short side ceiling beams 32 are arranged.
A reinforcing beam 40 is placed on A (see FIGS. 4 and 6). At this time, the positioning pins 53 provided at the pillar omitted corners of the short side ceiling beam 32A are inserted into the holes 421 formed in the respective shear plates 42 in the pillar omitted joints 20.
As a result, the large space building units 121A and 121B
Are simultaneously performed (see FIGS. 5 and 6). In this state, a substantially lower half of the reinforcing beam main body 41 is sandwiched between the short side ceiling beams 32A, and a substantially lower half of the stiffener 43 is sandwiched between the long side ceiling beams 32B (see FIG. 6).

Then, the large space building units 122A and 122B constituting the second floor are placed on the large space building units 121A and 121B on the lower floor. At this time, the tip of the protruding positioning pin 53 is inserted through the hole 421 and inserted into a hole (not shown) provided on the lower surface of the column omitted corner portion of the short side floor beam 33A on the upper floor. In addition, sheer
Through the holes 422 provided in the plate 42, the upper and lower large space building units 122A (122B) and 121A
(121B) with the fastening bolt 54 and the fastening nut 55 (see FIG. 5). Thereafter, the deformation preventing bolts 51 are screwed into the plurality of nuts 52 provided on the short side floor beam 33A, and the ends of the deformation preventing bolts 51 are brought into contact with the reinforcing beam main body 41 from both sides of the reinforcing beam main body 41. Thereby, the reinforcing beams 40 and the upper-floor large space building units 122A, 12A
2B short side floor beam 33A and lower-floor large space building unit 1
Joining of the short side ceiling beams 32A of 21A and 121B is completed. Here, the temporary pillar 37 is removed, and a large space in which no obstacle such as the pillar 31 exists in the living room is formed.

According to the above-described embodiment, the following effects can be obtained. (1) Since the reinforcing beam deformation preventing structure 50 including the nut 52 and the deformation preventing bolt 51 is used, the reinforcing beam main body 41 is used.
Even if the plate is thin, the curvature can be reliably prevented. (2) The deformation preventing means is a very simple one using the deformation preventing bolt 51, and its manufacturing cost can be reduced. (3) Since the deformation preventing bolts 51 are disposed opposite to each other with the reinforcing beam main body 41 interposed therebetween, the reinforcing beam main body 41 is provided from both sides.
Can be reliably held down and the bowing can be prevented.

(4) Since a plurality of deformation preventing bolts 51 are arranged along the longitudinal direction of the reinforcing beam main body 41,
Even if the reinforcing beam 40 is long, its bending can be reliably prevented. Therefore, a living room having a wider space can be formed. (5) Since the deformation preventing bolt 51 is screwed to the nut 52 fixed to the short-side floor beam 33A, its attachment is easy. Further, since the conventional structure can be adopted as the basic structure of the reinforcing beam main body 41, the manufacturing cost can be reduced.

(6) Shear plate 4 used for positioning
2 is pre-attached to the reinforcing beam main body 41, so that the reinforcement of the column omitted joint 20 in the large space building units 121A and 121B and the adjacent large space building unit 1
Positioning of 21A and 121B can be performed simultaneously. (7) The strength of the reinforcing beam 40 can be improved by the stiffeners 43 arranged orthogonally to the reinforcing beam main body 41. Therefore, the reinforcing beam main body 41 can be made thinner and lighter, and the material cost can be reduced. (8) By sandwiching the stiffener 43 between the shear plates 42, the bonding strength of the stiffener 43 can be improved. Further, the reinforcing beam main body 41, the stiffener 43, the shear plate 4
Since the two members are orthogonally joined to each other and integrated, the strength of the entire reinforcing beam 40 can be improved.

(9) Since the cross section of the shear plate 42 is formed in an L-shape, its mounting becomes easy.
In addition, since the joint area between the reinforcing beam main body 41 and the shear plate 42 can be secured to some extent, the joint strength between them can be increased. (10) Shear plate 42 at pillar-less joint 20
Since the two sides are bent, not only can the joint strength with the reinforcing beam main body 41 be improved, but also the joint strength with the stiffener 43 can be improved. Therefore, the strength of the entire reinforcing beam 40 can be increased. Further, the positioning of the large space building units 121A and 121B can be performed more reliably. (11) Since the shear plate 42 is provided on the reinforcing beam main body 41, the positioning work of the adjacent large space building units 121A and 121B can be easily performed when the unit-type building 10 is constructed. In addition, the reinforcing beam main body 41,
Since the three members of the plate 42 and the stiffener 43 are integrated to improve the strength of the reinforcing beam 40 and the use of the reinforcing beam deformation preventing structure 50, the rigidity is improved by using the lighter reinforcing beam 40. Of the unit-type building 10 with high height can be obtained.

It should be noted that the present invention is not limited to the above embodiment, and modifications and improvements as long as the object of the present invention can be achieved are included in the present invention.

In the above embodiment, the reinforcing beams 40 are used as the short side ceiling beams 3 of the large space building units 121A and 121B.
2A was reinforced, but not limited to this.
B may be reinforced. However, it is preferable that the reinforcing beams 40 reinforce the short side ceiling beams 32A, since higher rigidity can be secured than in the case of reinforcing the long side ceiling beams 32B. Further, the reinforcing beam main body 41 is formed in a plate shape, but is not limited to this, and may have another shape such as a column shape or a flat block shape. However, it is preferable that the reinforcing beam main body 41 be formed in a plate shape because the weight can be reduced. On the other hand, by forming a pillar shape, the space between the large space building units 121A and 121B is widened, and a living room having a wide space can be formed accordingly.

As shown in the first to third modified examples of FIGS. 10 to 12, a member in which reinforcing members 45, 46 and 47 are joined to a reinforcing beam main body 41 may be used. By doing so, the section modulus of the reinforcing beam 40 is improved, and the strength of the reinforcing beam 40 is preferably improved. The reinforcing member 4
5, 46, and 47 may be attached along the longitudinal direction of the reinforcing beam main body 41 by the same length as the reinforcing beam main body 41, or may be divided into small pieces and attached at an appropriate position in an arbitrary number. Good.

In the above embodiment, the shear plate 4
For 2, the rectangular metal plate has at least one side bent, but a rectangular plate that is not bent may be used as it is. However, bending is preferable because the joint surface between the reinforcing beam main body 41 and the stiffener 43 can be increased, and the joint strength of each member can be increased. The shape does not need to be rectangular, and may be, for example, a trapezoid or the like, as long as it can be positioned. The shear plate 42 has a total of four large space building units 121A, 12 each of two.
Although it was provided on both sides of the reinforcing beam main body 41 in order to perform positioning of 1B, the present invention is not limited to this, and it may be used for positioning one large space building unit 121A, 121B. In this case, The shear plate 42 is provided only on one side of the reinforcing beam main body 41.

In the above-described embodiment, the stiffener 43 is formed in a rectangular shape in a plane. However, the present invention is not limited to this. Further, all the components of the reinforcing beam 40 are made of metal,
Other materials may be used as long as they have a reinforcing effect.

In the above embodiment, the reinforcing beam deformation preventing structure 50 uses the nut 52 and the deformation preventing bolt 51. However, the structure is not limited to this, and any structure that can prevent the bending of the reinforcing beam main body 41 can be used. I just need. Reinforcement beam deformation prevention structure 5
Although 0s are provided in a line along the longitudinal direction of the reinforcing beam main body 41, the present invention is not limited to this, and two or more lines may be provided. Further, in the above-described embodiment and each of the modified examples, the reinforcing beam deformation preventing structure 50 is provided on both sides of the reinforcing beam main body 41, but is not limited thereto, and may be provided on one side. However, it is preferable to provide the reinforcing beam main body 41 on both sides because the deformation of the reinforcing beam main body 41 can be reliably prevented.
