BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a reinforcing beam mounting structure for reinforcing a beam by mounting a reinforcing beam between opposing beams, and a unit building in which the opposing beams are connected by the reinforcing beam mounting structure.

[0002]

Description of the Related Art A unit building is manufactured in advance in a factory, and is provided with a box-shaped, almost finished inside and outside building unit and a roof unit / roof panel of a certain size that can be transported. It transports a plurality of building units, roof units, and roof panels to the construction site and assembles them at the construction site to form a building.
In recent years, it has been widely adopted because it has the feature of being a standardized building with good dimensional accuracy. 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. 61-42061 (hereinafter referred to as Conventional Example 1) discloses four pillars arranged at four corners of a rectangular shape.
The framework of the building unit is described, which consists of a ceiling beam connecting the upper ends of the four pillars along a rectangular side, and a floor beam connecting the lower ends of the four pillars along a rectangular side. ing. Then, a ceiling edge is inserted over the opposing ceiling beam, a ceiling material is attached to the lower surface of the ceiling edge, a ceiling is formed, a floor beam is inserted over the opposing floor beam, and a floor joist is mounted thereon, Since floor materials are attached to this floor joist to form a floor, studs are attached between ceiling beams and floor beams, and outer and inner wall panels are attached to these studs to form walls and building units. is there.

Further, Japanese Patent Application Laid-Open Nos. 8-277580 and 9-317021 (referred to as Conventional Example 2) disclose:
A temporary column is provided at the column omitted corner, and a building unit having a skeleton of substantially the same structure as that of the conventional example 1 is installed. Between the ceiling beam of one building unit and the ceiling beam of the other building unit that passes through the building, a reinforcing beam of approximately twice the length of the ceiling beam is inserted. A unit building having pillar omitted corners from which temporary pillars are removed after connection is described.

Japanese Unexamined Patent Application Publication No. 10-61021 (hereinafter referred to as Conventional Example 3) discloses three or four building units in which provisional columns are provided at corners where columns are omitted, which have substantially the same structure as Conventional Example 2. The cross-shaped reinforcing beam is installed in the space between the adjacent cross-shaped building units at the corner where the pillar is omitted, and a cross-shaped reinforcing beam is inserted between the adjacent building units. A unit building having a pillar-eliminated corner where a temporary pillar is removed after connecting beams is described.

When manufacturing the building units described in Conventional Examples 1 to 3, Japanese Patent Publication No. 63-1111
As described in Japanese Patent Publication No. 4 (hereinafter referred to as Conventional Example 4),
The column and the beam are connected via a joint material without being directly connected. In Japanese Patent Publication No. 2-1375 (hereinafter referred to as Conventional Example 5), a joint box is located at four corners of a rectangular shape, the joint box is connected by four beams, and a pillar is attached to the joint box at the four corners. The building unit in which is erected is described.

[0007]

Generally, when building units are arranged side by side in a horizontal direction to assemble them into a unit building, it is necessary to prevent the building units from moving apart when a horizontal force such as a wind is applied or when the building is vibrated by an earthquake or the like. Moreover, in order to improve the strength of the beams, beams such as the ceiling beams and floor beams of the building units are connected to the opposing ceiling beams and floor beams of the adjacent building units by bolts and nuts. .

However, in the building units described in the prior art examples 1 to 4, since the columns and the beams are connected by the joint members, the joint members protrude outside the beam surface by the thickness of the joint members. Therefore, when the building unit and the adjacent building unit are installed with the beams facing each other, a gap between the facing beams is twice or more the thickness of the joint material.

Also, in the building unit described in Prior Art Example 5, since the beam and the column are connected by the joint box, this joint box protrudes outside the beam surface by the thickness of the joint box. Therefore, as described above, when the building unit and the adjacent building unit are installed with the beams facing each other, a gap that is twice or more the thickness of the joint box is generated between the facing beams. And since this joint material or joint box is required to have mechanical strength that is almost the same or more than that of a beam or a column, the thickness of this joint material or joint box is usually about the same or more than that of a beam or a column. Use those. Therefore, a gap of twice or more the thickness of the beam is generated between the beam of the building unit and the beam of the adjacent building unit. Then, when connecting these two opposing beams with bolts and nuts, the beams are deformed and cannot be firmly connected,
There is a problem that the building units move apart and the strength of the beam does not improve.

Therefore, usually, a small piece spacer having a thickness twice or more the thickness of the beam is interposed between the opposing beams and connected by bolts and nuts. Further, in the unit buildings having the pillar omitted corners described in the conventional example 2 and the conventional example 3, in order not to reduce the mechanical strength of the pillar omitted corners, a long reinforcing beam is used as the beam of one building unit. The reinforcing beam and the beam are connected along the beam of the other building unit, and the reinforcing beam also needs to be twice as thick as the spacer for the same reason as the spacer.

As described above, in the conventional building unit, when it is installed adjacent to the building unit, the thickness of the reinforcing beams and spacers sandwiched between the beams on both sides needs to be at least twice the thickness of the beams. Was. However, the thicker the metal plate, the more expensive it becomes. Processing such as cutting or shaping according to the shape of the beam in order to insert it between the beams, or providing a through hole for attaching to the beam is required. However, when the thickness is large, the processing becomes difficult.

Further, the skeleton of the building unit is subjected to a rust-preventive treatment by plating or the like. In order to maintain the durability of the reinforcing material substantially equal to that of the skeleton of the building unit, a steel plate is used as a reinforcing plate. Sometimes, it is necessary for this reinforcing material to be similarly subjected to rust prevention treatment. However, when the reinforcing material becomes thicker than twice the thickness of the connecting material and joint box,
Plating becomes difficult.

That is, in general, when plating a thin steel sheet, a so-called dowel is made by passing a steel sheet wound in a coil shape through a tank of, for example, zinc or tin that is bent and melted while being unwound from the coil. Mass production by pickling plating,
When the thickness is twice or more, the steel sheet becomes difficult to bend and is difficult to pass through a molten zinc or tin tank. Therefore, it is necessary to dip the small cut pieces in molten zinc or tin or to perform electroplating, which makes mass production difficult and expensive.

In the above description, the problem with the reinforcing beams in the unit building has been described. However, in a general building, the same applies when reinforcing beams are inserted between opposing beams to reinforce the beams. Problem. Therefore, an object of the present invention is to provide an inexpensive reinforcing beam mounting structure in which a reinforcing beam is attached to a building beam to reinforce the beam, and a unit building in which the opposing beam is reinforced by the reinforcing beam mounting structure. is there.

By the action, the reinforcing beam can be easily and inexpensively manufactured,
The ceiling beams and floor beams on both sides are firmly connected by the reinforcing beams.

In addition, since the height of the reinforcing beam at this time is substantially equal to the sum of the ceiling beam of the building unit on the lower floor and the floor beam on the upper floor, the reinforcing beam is extremely high and the vertical The mechanical strength (bending and bending strength) is extremely large. Therefore, the mechanical strength of the beam to which this reinforcing beam is attached is extremely large,
