Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a reinforcing structure for a unit-type building constructed by combining a plurality of building units produced in a factory.

[0002]

2. Description of the Related Art As a construction method of a building, the work conventionally performed at a construction site is performed as much as possible at a factory, thereby reducing the amount of work at the construction site, reducing costs and improving quality. Unit construction methods are known.
In this unit construction method, a building is built in advance by producing a plurality of building units at a factory, transporting these building units to a construction site, and connecting and combining them vertically and horizontally. Is a rectangular parallelepiped with a ramen structure formed by erection of four beams between upper ends and lower ends of four pillars erected at four corners.

[0003]

By the way, it is possible to construct a floor plan of various variations by connecting and combining a plurality of rectangular parallelepiped building units of a fixed size. In order to obtain more floor plan variations, rather than combining multiple building units of the same size, multiple building units with different lengths of beams, which are structural members of the building units, in other words, horizontal units In some cases, it is necessary to use a long-sized building unit having a long length in the direction and a short-sized building unit having a short length in the same direction as the horizontal direction, and to arrange these vertically adjacently.

Pillars and beams, which are structural materials of each building unit, have a small cross-sectional area so as to exhibit the required strength and strength as a whole building only when a building is constructed by connecting and combining a plurality of building units. The building unit is designed to save material. When producing the long and short building units mentioned above,
Due to the demand for unified materials, the beams of these building units are made of the same material. The strength and proof strength of the long-dimension building unit itself become larger than the strength and proof strength of the long-dimension building unit itself by the shorter beam length.

However, when a building is constructed by vertically arranging a long building unit and a short building unit having different strengths and proof strengths, when a load caused by an earthquake or a typhoon acts on the building, The unit and the short-sized building unit do not evenly support the load, and the short-sized building unit having high strength and proof strength will support more load than the long-sized building unit. According to this, the load acts intensively on the short-sized building unit, and the load support becomes uneven when viewed as a whole building, which is not preferable.

SUMMARY OF THE INVENTION It is an object of the present invention to reinforce a unit-type building which can prevent a concentrated load from acting on a short-sized building unit even when a long-sized building unit and a short-sized building unit are connected and combined. It is where the structure is provided.

[0007]

According to the present invention, there is provided a reinforcing system for a unit-type building, wherein a rectangular parallelepiped building unit is constructed by installing four beams between upper and lower ends of four pillars at four corners. A plurality of the building units are connected and combined in at least the up-down direction in the up-down direction and the horizontal direction, and one of two building units adjacent in the up-down direction is a long-sized building unit having a long horizontal length. Further, in a unit type building in which the other is a short-sized building unit having a short length in the same direction as the horizontal direction, a reinforcing member is assembled to the long-sized building unit.

According to the present invention, when a long-sized building unit and a short-sized building unit are adjacent to each other in the vertical direction, a reinforcing member is assembled to the long-sized building unit. The same or almost the same strength as the building, so that when a load due to an earthquake or typhoon acts on the building, both the short and long building units can support the load equally or almost equally. It is possible to eliminate the intensive load acting on the short-sized building unit.

In the above, the number of short-sized building units in a unit building may be one or more. Further, the number of short-sized building units may be larger or smaller than the number of long-sized building units.

The horizontal length of the short building unit shorter than the long building unit may be only the length in one direction of the rectangular parallelepiped building unit, or may be the length in two directions forming a right angle.

Further, the vertical relationship between the long building units and the short building units vertically adjacent to each other may be such that the short building units may be at the top or the long building units may be at the top.

The unit-type building may be a two-story building, a multi-story building having more floors, or a building with a basement by a building unit.

The reinforcing member to be assembled to the long-sized building unit can have any shape and structure as long as the strength and the proof stress of the long-sized building unit can be increased.
One example is a rod-shaped member, and the other example is a rod-shaped member combination in which a plurality of rod-shaped members are coupled. These bar-shaped members and the bar-shaped member combination are bridged between two beams facing each other and being parallel as structural members of a long-sized building unit. These two beams may form a horizontal ceiling surface or floor surface of a long-sized building unit, or may form a vertical wall surface.

In the case where the reinforcing member is a rod-shaped member combined member,
Each rod-shaped member forming the rod-shaped member combination may be individually assembled to the long-sized building unit and may be a constituent member of the reinforcing member after all the assembling, but before assembly to the long-sized building unit, It is preferred to produce a bar assembly by joining all of the bar members as a panel, and to assemble this panel into a long building unit.

[0015] In this case, the rod-shaped member combination as the reinforcing member can be produced as a panel separately from the long-sized building unit, and the handling thereof is facilitated.

The length, shape and number of the plurality of rod-like members forming the rod-like member combination are arbitrary.
For example, one or a plurality of short-length bar-shaped members may be erected at right angles between two parallel long-diameter bar-shaped members, or may be erected diagonally. 1 extending to beams and columns of long-sized building units
It may be one in which the ends of two or more short-sized rod-shaped members are joined.

The position where the bar-shaped member assembly is disposed is a ceiling formed by the four beams on the upper side of the long-sized building unit, and the height of these four beams is a vertical dimension. If a ceiling beam with a height smaller than the height of the beam is placed at a height lower than the ceiling upper surface, place the bar-shaped assembly in the space above the ceiling beam in the vertical dimension of the ceiling. Is preferred.

In this case, the combined rod-shaped member can be effectively stored and arranged in the empty space above the ceiling beam, and the overall height of the long-sized building unit does not change. Design and assembly work can be the same as before.

In the case where the brace is provided in the long-sized building unit, a bracket for connecting the end of the brace is connected to the bar-like member combination arranged on the ceiling, wall, or floor of the long-sized building unit. Is preferably provided.

If such a bracket is provided on the rod-like member combination, the rod-like member combination also serves as a mounting member at the end of the brace, so that the structure of the long-sized building unit can be simplified. When the above panel is used, when this panel is assembled to a long-sized building unit,
Since the bracket is also attached to the long-sized building unit at the same time, the work can be facilitated.

Further, the bar-shaped member combined body may be one in which a peripheral portion is formed by the plurality of bar-shaped members, and a center portion is a space without the bar-shaped member. When the bar-shaped member combination is configured as described above, an opening (for example, a window) required to be provided in a long-sized building unit can be formed in a central space where no bar-shaped member is provided. Even if the position of the opening required to be provided in the building unit coincides with the position of the rod-shaped member assembly required to be assembled in this long-sized building unit, a design that simultaneously satisfies these requirements can be achieved. .

Pieces of short-sized building units 1B. The upper beams on the long sides and the lower beams on the short sides of the building units 1A, 1B on the upper floor and the building unit 1A on the lower floor are parallel.

For this reason, the short dimension building unit 1B
Is protruded forward from the short-sized building unit 1B by the difference between the lengths of the upper and lower beams of the longer and lower sides of the building units 1A and 1B. Having.

The long-sized building units 1A and the short-sized building units 1B constituting the unit-type building 30 are
And long building unit 1A and short building unit 1
B is connected and combined via connection members such as bolts, nuts, connection pins, and connection plates.

In the embodiment shown in FIG. 2, a bar-shaped member 11 as a reinforcing member 10 for increasing the strength and strength of the long-sized building unit 1A is provided on the long-sized building unit 1A below the short-sized building unit 1B.
