DETAILED DESCRIPTION OF THE INVENTION

[0001]

The present invention relates to a unit building having good vibration damping properties.

[0002]

2. Description of the Related Art In a unit building, a box-shaped building unit having a fixed size, which can be transported, and finished inside and outside, and a roof unit and a roof panel are manufactured in a factory in advance. A unit that transports multiple units, roof units, and roof panels to the construction site and assembles it at the construction site to form a building.The feature of this site is that it is a standardized building with a short on-site construction period and high dimensional accuracy. Therefore, it has been widely adopted in recent years. In some cases, the roof panel is attached to a building unit in a factory and transported to a construction site.

Various types of building units are known as building units used in this unit building. For example,
Japanese Patent Publication No. Sho 61-42061 discloses four pillars erected at four corners of a rectangular shape, a ceiling beam connecting upper end portions of the four pillars along a rectangular side, and the four pillars. A skeleton of a flat rectangular building unit including floor beams connecting lower ends of pillars along rectangular sides is described. Then, a ceiling beam is inserted between the opposed ceiling beams, a ceiling material is attached to the lower surface of the ceiling beam to form a ceiling, a floor beam is inserted between the opposed floor beams, and a floor joist is mounted thereon, A floor is attached to the floor joist to form a floor, and where a wall is to be provided, a stud is attached between the ceiling beam and the floor beam, and an outer wall panel or an inner wall panel is attached to the stud to form a wall. To make a building unit.

In general, when walking or dropping an object on an upper floor, the floor vibrates, and an impact sound generated by the vibration reverberates on the lower floor, disturbing a person on the lower floor. become. In particular, in apartments such as condominiums where multiple households are living on the upper floor and the lower floor, the noise generated by the upper floor households affects the lower floors, and the lower floor households are annoying. It feels like a big social problem. In order to prevent such a situation, various floor structures with good anti-vibration properties are conventionally known for building units.

For example, in Japanese Patent Application Laid-Open No. 62-59745 (hereinafter referred to as Conventional Example 1), a floor beam is inserted between opposing floor beams, and the floor beam is provided with a vibration isolating pad interposed between the floor beams. A building unit having a floor structure connected by a leaf spring is described. Japanese Patent Laid-Open Publication No. Sho 63-304372 (hereinafter referred to as Conventional Example 2) discloses that a plurality of floor beams are extended substantially in parallel between opposing floor beams, and a vibration damping material is provided on the substantially parallel floor beams. A building unit with a floor structure with both ends attached is described. Japanese Unexamined Patent Application Publication No. 11-222019 (hereinafter referred to as Conventional Example 3) discloses a unit building assembled by interposing a vibration isolator between a ceiling beam of a building unit on a lower floor and a floor beam of a building unit on an upper floor. Is described.

On the other hand, in a unit building in which the above-mentioned building units are assembled, four pillars erected at four corners of a rectangular shape interfere with each other, and a large continuous space cannot be formed in a portion having pillars. Therefore, there is a problem that a large room cannot be provided. As a unit building that solves such a problem, a unit building described in Japanese Patent Application Laid-Open No. 8-277580 (referred to as Conventional Example 4) is known.

The unit building described in this publication has a pillar omitted corner in which a pillar, a floor beam, and a ceiling beam are connected in a rectangular box shape, and the pillar is omitted in one corner of the flat rectangular shape. Two to four building units are installed with the pillar omitted corners facing each other, and from the side of the ceiling beam of the building unit having one pillar omitted corner which is substantially straight and the pillar omitted corners are joined, and the other. This is a building in which a reinforcing beam is attached to a side surface of a ceiling beam of a pillar omitted building unit having a pillar omitted corner, and the reinforcing beam is connected to the ceiling beam. In this unit building,
This is extremely convenient because a continuous wide space can be formed from a building unit having one pillar omitted corner to a building unit having the other pillar omitted corner at the pillar omitted corner where the pillar is omitted.

[0008]

However, in the floor structures described in the prior art examples 1 and 2, the vibration of the floor is absorbed by vibration-proof pads, leaf springs, vibrating members and the like, so that the floor impact noise is reduced. Although it is easy to reduce the weight impact noise with this floor structure, it is difficult to reduce the weight impact noise. This is considered to be because the weight impact sound is a sound generated by the vibration of the whole building unit due to the floor vibration and the vibration of the building unit on the lower floor.

In the method described in the prior art example 3, the vibration damping material is interposed between the ceiling beam of the building unit on the lower floor and the floor beam of the building unit on the upper floor, so that the entire building unit on the upper floor vibrates. The vibrations absorbed between the building units on the upper floor and the building units on the lower floor can be absorbed and the heavy impact noise can be prevented, which is convenient. The thickness of the vibration isolating material between the ceiling beam and the floor beam cannot be increased, and the contact area between the vibration isolating material and the ceiling beam is relatively small. There is a problem that the sound has a limit and cannot absorb a heavy impact sound.

[0010] In particular, in a unit building having a column omitted corner as described in Conventional Example 4, a ceiling beam of a building unit having one column omitted corner passing through a column omitted corner reinforced by a reinforcing beam is provided. There is a ceiling beam having a long span up to the ceiling beam of a building unit having the other column omitted corner, and there is no pillar in the middle of this ceiling beam for suppressing vibration. The vibration of the ceiling beam having a long span is large, and it is extremely difficult to absorb a heavy impact sound having a large vibration by the vibration isolator provided between the ceiling beam and the floor beam. Therefore, an object of the present invention is to provide a ceiling beam having a long span from a ceiling beam of a building unit having one pillar omitted corner to a ceiling beam of a building unit having the other pillar omitted corner, which is reinforced with a reinforcing beam. An object of the present invention is to provide a unit building with low noise capable of absorbing an impact sound.

[0011]

Means for Solving the Problems The present invention has been made to achieve the above object, and the invention according to claim 1 has a structure in which columns, floor beams, and ceiling beams are formed into a rectangular box shape. Concatenate,
Further, in a unit building in which two to four building units each having a pillar omitted corner in which the pillar is omitted in one corner of the plane rectangular shape are installed with the pillar omitted corners facing each other,
From the side of the ceiling beam of the building unit having one pillar omitted corner which is substantially linear with the pillar omitted corner, the side of the ceiling beam of the building unit having the other pillar omitted corner is reinforced. A plate-like composite material obtained by superimposing a beam and a damping material is added, and this composite material is connected to a ceiling beam.

According to a second aspect of the present invention, a column, a floor beam, and a ceiling beam are connected in a rectangular box shape, and a pillar omitted corner portion in which the pillar is omitted in one corner of the flat rectangular shape. In a unit building in which four to four building units are installed with the pillar omitted corners facing each other, the ceiling of the building unit having one of the pillar omitted corners that is substantially linear and the pillar omitted corners are joined together A reinforcing beam is attached to the side of the ceiling beam of the building unit having the other pillar omitted corner from the side of the beam, and the reinforcing beam is connected to the ceiling beam with a plate-shaped vibration damping material interposed therebetween.

The vibration damping material in the present invention absorbs and controls vibration, and is preferably made of rubber such as natural rubber or synthetic rubber, or soft synthetic resin such as soft vinyl chloride resin or soft urethane resin. is there. The plate-like composite material in which the reinforcing beam and the vibration damping material according to the first aspect of the present invention are superposed is a plate-like body in which a reinforcing beam having high mechanical strength such as metal and the above-described vibration damping material are superposed. The number of the reinforcing beams and the damping materials to be superimposed may be appropriately determined. For example, one obtained by superposing one reinforcing beam and one damping material may be used, one obtained by superposing two or more reinforcing beams and one damping material may be used, or one Reinforced beams and 2
It may be obtained by polymerizing two or more damping materials, or 2
What superimposed two or more reinforcing beams and two or more damping materials may be used.

In the case of a composite material in which two or more reinforcing beams or vibration damping materials are superimposed, it is preferable that they are superposed alternately. Among these, a composite material obtained by superposing a plate-shaped vibration damping material between two reinforcing beams or a three-layer composite material obtained by adding a vibration damping material to both sides of one reinforcing beam and polymerizing is preferable. In the case of a composite material in which a plate-shaped damping material is sandwiched between two metal plates, (thickness of metal plate) :( thickness of damping material) = 1: 2 to 5 is preferable.

The method of superimposing the reinforcing beam and the vibration damping material may be appropriate. For example, they may be bonded with an adhesive. In particular, in the case of a composite material having metal plates on both outer sides, a composite material in which the metal plates on both sides are connected by sport welding or bolting is preferable. When connecting a composite material having a metal plate on both sides to a ceiling beam, it is preferable to connect with a high-strength bolt because the connection can be made firmly. When there is a damping material on both sides or when a plate-shaped damping material is interposed between the composite material and the ceiling beam, it is difficult to connect firmly with high-strength bolts, so it is preferable to connect with normal bolts.

According to the second aspect of the present invention, the reinforcing beam is attached to the ceiling beam with the damping material interposed therebetween. This is because most of the contact surfaces between the reinforcing beam and the ceiling beam use the damping material. It means that it is only necessary to be able to absorb the vibration of the ceiling beam with the damping material. Therefore, there may be a place where there is no damping material. For example, if a metal contact plate is installed in a place where there is no damping material and this part is connected with high-strength bolts, it can be connected firmly in the place where the contact plate is located,
This is preferable because vibration can be absorbed at a place where the vibration damping material is located. Alternatively, the locations of the contact plates may be connected by high-strength bolts, and the locations of the damping materials may be connected by ordinary bolts and nuts.

(Function) According to the first aspect of the present invention, a ceiling beam of a building unit having a pillar omitted corner from the side of a ceiling beam of a building unit having one pillar omitted corner which is substantially linear. A plate-shaped composite material in which a reinforcing beam and a vibration damping material are superimposed is attached to the side surface of the building, and this composite material is connected to the ceiling beam. Dropping an object on the floor, the floor vibrates, and as a result,
Even if the ceiling beam of the building unit on the lower floor vibrates, this vibration is absorbed by the damping material in the composite material connected to the ceiling beam and is not propagated to the adjacent building unit.

Moreover, the height of the vibration damping material in the composite material can be set to the height from the top to the bottom of the ceiling beam or the height from the ceiling beam on the lower floor to the floor beam on the upper floor. it can. As described above, vibration can be absorbed by the vibration damping material having a large area having a large area, so that vibration of a ceiling beam which generates a loud impact sound can be absorbed. Further, a ceiling beam of one building unit can be absorbed. Even if the ceiling beam has a long span from the ceiling beam of the other building unit to the ceiling beam, the floor vibration can be absorbed. Therefore, people on lower floors are not uncomfortable.

According to the second aspect of the present invention, the side of the ceiling beam of the building unit having one pillar omitted corner from the side of the ceiling beam of the building unit having the other pillar omitted corner is substantially linear. Since a reinforcing beam is attached and this reinforcing beam is connected to the side of the ceiling beam with a plate-shaped damping material in between,
Even if the floor vibrates by walking on the floor of the building unit on the upper floor or dropping an object on the floor, and as a result the ceiling beams of the building unit on the lower floor vibrate, this vibration will not It is absorbed by the plate-shaped damping material between the beam and the reinforcing beam, and is not transmitted to the adjacent building unit.

In addition, the height of the contact surface between the ceiling beam and the damping material can be set from the top to the bottom of the ceiling beam. As described above, vibration can be absorbed by the high and wide contact surface between the damping material and the ceiling beam, so that the vibration of the ceiling beam that generates a large weight impact sound can be absorbed. Even a ceiling beam having a long span from a ceiling beam of a building unit to a ceiling beam of another building unit can absorb floor vibration. Therefore, people on lower floors are not uncomfortable.

Vibrations that generate heavy impact noise can also be absorbed, and floor vibrations can be absorbed even from a long span from the ceiling beam of one building unit to the ceiling beam of the other building unit. Therefore, people on lower floors are not uncomfortable.

According to the second aspect of the present invention, from the side of the ceiling beam of the building unit having one pillar omitted corner which is substantially linear, the side of the ceiling beam of the building unit having the other pillar omitted corner is formed. Reinforcement beams are attached, and the reinforcement beams are connected to the ceiling beams with a plate-shaped damping material interposed between them, so they can walk on the floor of the building unit on the upper floor or drop objects on the floor. Even if the floor vibrates and the ceiling beam of the building unit on the lower floor vibrates as a result, this vibration is absorbed by the plate-shaped damping material between the ceiling beam and the reinforcing beam, and Not propagated to units.

Moreover, since the height of the vibration damping material can be made substantially the same as the height of the ceiling beam, it is possible to absorb the vibration that generates a loud impact noise, and furthermore, it is possible to absorb the vibration of one of the building units. Even in a long span from the ceiling beam to the ceiling beam of the other building unit, floor vibration can be absorbed. Therefore, people on lower floors are not uncomfortable.
