[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a reinforcing beam and a unit building including the reinforcing beam.
[0002]
[Background]
Conventionally, a unit type building in which a plurality of box-shaped building units manufactured at a factory are combined at a construction site is known. As a building unit that forms a unit type building, a building unit having a rectangular parallelepiped frame in which the upper and lower ends of columns erected at four corners are respectively connected by a ceiling beam and a floor beam is generally used. If one attempts to create a large living room by combining a plurality of such building units, a plurality of pillars will be concentrated in the center, and thus a large space without pillars cannot be formed.
[0003]
For this reason, a method is adopted in which a wide space is created by combining a plurality of building units (hereinafter referred to as large-sized building units) from which a part of a pillar is omitted from a normal building unit framework.
However, when such a large space building unit is used, the pillars are partially omitted, so that the rigidity of the framework is lowered, and there is a possibility that the load of the building unit or the like placed above cannot be supported. is there. In order to solve this, center the portion where some of the pillars are omitted and set the length between the upper ends of the pillars of each large space building unit arranged on both sides of the two spans, that is, the length of two units. It has been proposed to connect and reinforce with reinforcing beams (see JP-A-8-277580).
[0004]
Such a reinforcing beam is provided in each of the first floor part having a large space without a pillar and the second floor part formed on the upper part of the first floor part in the unit type building. In the first floor portion, first-floor reinforcing beams are provided between the ceiling beams of the building units forming the first floor portion, and between the floor beams of the building units forming the second floor portion. In the second floor portion, the second-floor reinforcing beam is provided between the ceiling beams brought together in each building unit forming the second floor portion.
That is, the portion where the first-floor pillar is omitted by the first-floor reinforcing beam is connected and reinforced, and the connection between the building units located at the upper part of the portion where the first-floor pillar is omitted is reinforced by the second-floor reinforcing beam. The By providing such a reinforcement beam for the second floor, the floor of the second floor part can be suspended through the pillar brought together in the center of the second floor part, and the upper floor load is applied to the part where the pillar of the first floor part is omitted. Reduced.
[0005]
[Problems to be solved by the invention]
By the way, the first floor reinforcing beam as described above is formed in an I-shaped cross section, and the second floor reinforcing beam is formed in a T-shaped cross section. Each reinforcing beam is subjected to a load in a substantially vertical direction due to the load of each building unit.
However, since the upper surface of the reinforcing beam for the second floor has a T-shaped cross section formed at substantially the same height as the upper surface of the floor beam of the building unit on the second floor, it is for the first floor formed with an I-shaped cross section. Compared to reinforced beams, it is weaker to load in the vertical direction. For this reason, the second-floor reinforcement beam cannot sufficiently suspend the floor of the second-floor part, and the upper-floor load to the part where the first-floor part column is omitted is not reduced so much. There is a problem that must be done. Further, since the second floor portion of the building receives a large force due to the influence of wind or the like, it is desired that the strength of the reinforcing beam is greater.
[0006]
An object of the present invention is to provide a reinforcing beam and a unit building that can sufficiently connect and reinforce each building unit when a large space without columns is formed inside the unit building.

[0008]
According to this invention, the reinforcing beam installed between the ceiling beams of each building unit forming the upper layer includes a portion protruding upward from the upper surface of the ceiling beam. That is, since the cross section of the reinforcing beam is long in the vertical direction, the reinforcing beam is stronger in the vertical direction due to the load of each building unit than the conventional reinforcing beam having a T-shaped cross section. Accordingly, the floor of the second floor portion can be sufficiently hung and the upper floor load to the portion where the pillar of the first floor portion is omitted can be sufficiently reduced, so that the building units can be sufficiently connected and reinforced.
[0009]
The invention according to claim 2 is characterized in that the reinforcing beam according to claim 1 is provided with a stiffener provided perpendicular to the longitudinal direction of the reinforcing beam main body and intersecting the shear plate. To do.

According to the present invention, the same effect as that of claim 1 can be expected. That is, by providing the upper floor reinforcing beam having a cross section that is long in the vertical direction in the upper layer, the connection between the building units in the upper layer can be sufficiently reinforced. Also, by providing lower floor reinforcement beams in the lower level where large spaces without pillars are formed, it is possible to reinforce the connection between building units for large spaces in lower levels, thus forming large spaces without columns inside. In doing so, it is possible to provide a unit building with high strength.
[0011]
According to a fourth aspect of the present invention, in the unit type building according to the third aspect, the upper floor reinforcing beam is provided perpendicular to the longitudinal direction of the reinforcing beam main body and intersecting the shear plate. A stiffener is provided.
[0012]
The invention according to claim 5 is the unit type building according to claim 3 or 4, wherein the upper floor reinforcing beam and the lower floor reinforcing beam are formed in the same shape. To do.
According to the present invention, since the upper floor reinforcing beam and the lower floor reinforcing beam are formed in the same shape, the same thing can be used for the upper floor reinforcing beam and the lower floor reinforcing beam, and the number of parts is reduced. it can.

[0024]
In the second floor portion, as shown in FIG. 7, the upper floor reinforcement 6B formed in the same shape as the lower floor reinforcement beam 6A described above is installed between the short-side ceiling beams 32A brought together in the building unit 3B. Thus, adjacent building units 3B are connected and reinforced.
Here, in the building unit 3 </ b> B arranged on the second floor portion, positioning pins 34 </ b> A protrude from the upper surface of the bracket 34 on the ceiling side, and these positioning pins 34 </ b> A are inserted through the insertion holes 63 </ b> A of the respective shear plates 63. The two building units 3B are positioned. In such a state that the insertion hole 63A of the shear plate 63 is inserted into the positioning pin 34A of each building unit 3B, the shear plate 63 and the upper surface of the bracket 34 of the building unit 3B are tightened with bolts and nuts, so that the building unit 3B is connected. That is, when the upper floor reinforcing beam 6B is installed between the adjacent short side ceiling beams 32A of each building unit 3B, the substantially lower half of the upper floor reinforcing beam 6B is sandwiched between the short side ceiling beams 32A. The substantially upper half protrudes upward from the upper surface of the short-side ceiling beam 32A.
[0025]
8 and 9, the upper floor reinforcing beam 6B is connected to the column 31 of the building unit 3B via the ceiling-side bracket 34, and the lower floor reinforcing beam 6A is connected to the building via the floor-side bracket 34. It is connected to the pillar 31 of the unit 3B. Accordingly, the lower floor reinforcing beam 6A and the upper floor reinforcing beam 6B are connected by the column 31 of the building unit 3B. The pillar 31 of the building unit 3B is a connecting member according to the present invention.
[0026]
In the present embodiment, the building units 3B and 4 are connected and reinforced using the lower-level reinforcing beams 6A and the upper-level reinforcing beams 6B as follows.
A plurality of building units 3A, 3B, 4 are manufactured at the factory and then transported to the building site. At this time, in order to prevent the large space building unit 4 from being deformed at the time of transportation, the temporary pillar 42 is provided at a portion where the pillar is omitted.
In the construction site, first, the building units 3A and 4 constituting the first floor portion are arranged adjacent to each other on the foundation 2, and the lower floor reinforcing beams 6 are placed between the short-side ceiling beams 43A. At this time, each large space building unit 4 is positioned by engaging the insertion hole 63 </ b> A of the shear plate 63 with the positioning pin 45 </ b> A of each bracket 45. In this state, the substantially lower half of the reinforcing beam body 61 is sandwiched between the short-side ceiling beams, and the substantially lower half of the stiffener 62 is sandwiched between the long-side ceiling beams.
[0027]
Next, the building units 3B constituting the second floor part are arranged adjacent to each other above the first floor part. At this time, each building unit 3B is positioned by engaging the engaging hole of the building unit 3B with the positioning pin 45A of each building unit 3A, 4. Then, the building units 4 are connected to each other by fastening the upper surface of the bracket 45 of the building unit 4 and the lower surface of the bracket 45 of the building unit 4 with bolts and nuts with the shear plate 63 interposed therebetween.
[0028]
Thereafter, a bolt 72 is screwed into the nut 71 of the reinforcing beam deformation preventing means 7, and the tip of the bolt 72 is brought into contact with the side surface of the reinforcing beam body 61 from both sides of the reinforcing beam body 61.
In the second floor portion, as in the first floor portion, the upper floor reinforcing beams 6B are installed between the short-side ceiling beams 32A of the building units 3B, and the building units 3B are positioned and connected to each other.
In addition, the floor side connection in the column omitting portions 5 between the large space building units 4 on the first floor is performed by fixing the flat plate-like rectangular plate 8 with bolts or the like across the upper surfaces of the brackets 45 on the floor side. (See FIG. 9).
[0029]
According to this embodiment as described above, the following effects are obtained.
That is, in the present embodiment, the upper floor reinforcing beams 6B installed between the short-side ceiling beams 32A of each building unit 3B forming the second-floor portion are portions protruding upward from the upper surface of the short-side ceiling beams 32A ( (Approximately half). In other words, the upper floor reinforcing beam 6B is longer in the vertical direction than the conventional reinforcing beam having a T-shaped cross section. Therefore, the upper floor reinforcing beam 6B is more resistant to a load in the vertical direction due to the load of each building unit 3B. It has become. Accordingly, the floor of the second floor portion can be sufficiently hung and the upper floor load on the column omitting portion 5 of the first floor portion can be sufficiently reduced, so that the building units 3B can be sufficiently connected and reinforced.
[0030]
In addition to the upper-level reinforcing beam 6B, the lower-level reinforcing beam 6A is also provided on the first floor where a large space without pillars is formed, thereby reinforcing the connection between the large-space building units 4 on the first floor. Therefore, when a large space without a pillar is formed inside, the unit building 1 having high strength can be provided.
[0031]
Since the upper floor reinforcing beam 6B and the lower floor reinforcing beam 6A are formed in the same shape, the upper floor reinforcing beam 6B and the lower floor reinforcing beam 6A can be used, and the number of parts can be reduced.
[0032]
Since the upper floor reinforcing beam 6B and the lower floor reinforcing beam 6A are connected by the column 31, the load applied to the lower floor reinforcing beam 6A can be supported by the upper floor reinforcing beam 6B via the column 31. Accordingly, it is not necessary to increase the cross-sectional area of the lower-level reinforcing beam 6A, and, for example, the boundary portion between the first-floor portion and the second-floor portion can be effectively used as, for example, piping, wiring space, and the like. .
[0033]
Since the pillar 31 of each building unit 3B forming the second floor part of the unit type building 1 also serves as a connecting member for connecting the lower-level reinforcing beam 6A and the upper-level reinforcing beam 6B, a connecting member is provided separately. The number of parts can be reduced.
[0034]
In the present embodiment, since the reinforcing beam deformation preventing means 7 for preventing the reinforcing beam main body 61 from bending is provided, even when the reinforcing beam main body 61 is a thin plate, the bending can be reliably prevented. Further, since the deformation preventing means 7 is very simple using the nut 71 and the bolt 72, it can be constructed economically. Furthermore, since the deformation preventing means 7 is provided along the longitudinal direction of the reinforcing beam main body 61 (longitudinal direction of each short side floor beam 33A), even if the reinforcing beam main body 61 is long, its deformation can be reliably prevented. .
[0035]
It should be noted that the present invention is not limited to the above-described embodiment, and modifications and improvements within a scope that can achieve the object of the present invention are included in the present invention.
For example, in the above-described embodiment, the pillar 31 of the building unit 3B is used as a connecting member that connects the lower floor reinforcing beam 6A and the upper floor reinforcing beam 6B. However, for example, a wire or the like may be used.
[0036]
In the above embodiment, the lower floor reinforcing beam 6A and the upper floor reinforcing beam 6B are formed in the same shape. However, the present invention includes a case where the lower floor reinforcing beam 6B is not formed in the same shape.
[0037]
In the above embodiment, the reinforcing beam deformation preventing means 7 is provided only on the lower floor reinforcing beam 6A. However, for example, it may be provided on the upper floor reinforcing beam 6B. Reinforcing beam deformation preventing means may be provided along the longitudinal direction of the short-side ceiling beams 32A brought together. Further, the case where the reinforcing beam deformation preventing means 7 is not provided is also included in the present invention.
[0038]
In the above embodiment, the lower floor reinforcing beam 6A is placed between the short side ceiling beams 43A of the large space building unit 4 and the upper floor reinforcing beam 6B is placed between the short side ceiling beams 32A of the building unit 3A. Although installed, for example, the lower floor reinforcing beam may be installed between the long side ceiling beams 43B, and the upper floor reinforcing beam may be installed between the long side ceiling beams 32B. However, it is possible to secure higher rigidity when reinforcing the short-side beam with the reinforcing beams 6A and 6B than when reinforcing the long-side beam.
[0039]
In the above embodiment, the lower floor reinforcing beam 6A and the upper floor reinforcing beam 6B are installed at substantially the same position in a plan view. For example, depending on the arrangement position of each building unit, the lower floor reinforcing beam 6B The reinforcing beam and the upper-level reinforcing beam may be installed in a cross shape.
[0040]
In the above-described embodiment, the second floor portion of the unit type building 1 is configured by the normal building unit 3B. For example, even if a large space without a pillar is formed on the second floor portion using a large space building unit. Good.
[0041]
In the above embodiment, a large space without a pillar is formed in the first floor portion of the unit type building 1. For example, when the unit type building has three stories, a large space without a pillar in the second floor portion is formed. In short, the unit type building has at least one level in which a large space without pillars is formed, and each of this level and an upper level provided on the adjacent upper part of this level respectively. The reinforcement beam for lower floors and the reinforcement beam for upper floors should just be provided.
[0042]
【The invention's effect】
The present invention has the following effects.
In other words, according to the first aspect of the present invention, the reinforcing beam installed between the ceiling beams of each building unit forming the upper hierarchy has a portion protruding upward from the upper surface of the ceiling beam. That is, since the cross section of the reinforcing beam is long in the vertical direction, the reinforcing beam is stronger in the vertical direction due to the load of each building unit than the conventional reinforcing beam having a T-shaped cross section. Therefore, the floor of the second floor part can be sufficiently suspended, and the upper floor load to the part where the pillar of the first floor part is omitted can be sufficiently reduced, so that each building unit can be sufficiently connected and reinforced. effective.
