Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a beam reinforcing member of a unit-type building for reinforcing a plurality of beams arranged close to a plurality of building units arranged in a unit-type building.

[0002]

2. Description of the Related Art Conventionally, there has been known a unit-type building constructed by assembling a plurality of building units manufactured in a factory in advance at a building site. In such a unit-type building, the work of assembling a frame by joining columns and beams,
Most of the work of assembling building members, such as attaching face materials such as interior materials and exterior materials to the frame, is performed at the factory,
There is an advantage that the amount of work at the construction site is greatly reduced, and the work can be performed in a short time. Today, a plurality of types of frames having different dimensions are prepared, and architectural members such as interior materials and exterior materials have various materials having different materials, shapes, surface finishes, and the like. For this reason, by selecting and combining from various forms and variations, even though it is a unit type building,
A wide variety of forms can be built.

[0003]

In such a building unit, the deflection amount of the beam becomes uneven due to the difference in the weight of the exterior material or the like supported by the beam or the difference in the length of the beam. May be. In this case, it is conceivable to change the thickness dimension of the beam to make the amount of deflection uniform. However, when the thickness dimension of the beam is changed, not only does the type of beam increase, but also a joining structure or the like corresponding to the dimension of the beam becomes necessary, and the types of joining members and the like also increase, and the types of members constituting the building unit and There is a problem that the number further increases and member management becomes significantly difficult. On the other hand, instead of changing the thickness of the beam, use a beam with a uniform thickness,
In addition, it is conceivable to reinforce the beam according to the length of the beam, the load applied to the beam, and the like. However, since the work of attaching the reinforcing member to the beam to the beam is time-consuming, when attaching the reinforcing member in the factory, the manufacturing work of the building unit is complicated, the delivery time of the building unit is prolonged, and the installation is performed at the building site. Causes the problem of prolonging the construction period of the building. Also, if the reinforcing member for reinforcing the beam protrudes significantly from the lower surface, upper surface, or side surface of the beam, it interferes with the surface material such as the ceiling material, floor material, and wall material. In this case, the reinforcing member cannot be accommodated, and if a special fitting according to the reinforcing member is separately set, the type and the number of members constituting the building unit further increase from this point, and the member management becomes difficult. Occurs.

SUMMARY OF THE INVENTION It is an object of the present invention to unify the thickness of a beam to facilitate member management and to facilitate work at a construction site. Is to provide.

[0005]

According to a first aspect of the present invention, a plurality of building units each having a frame formed by columns and beams are arranged vertically and horizontally, and a plurality of beams arranged close to each other are arranged. A beam reinforcing member of a unit building for reinforcement, wherein a gap is formed between the plurality of beams,
The beam reinforcing member is a long one arranged along a beam to be reinforced of the building unit, and includes a main body that fits inside the gap, and the main body has a cross-sectional shape extending in a vertical direction. And not protruding from the inside of the gap. In the first aspect of the present invention, since the cross-sectional shape of the main body extends in the vertical direction, rigidity with respect to the load in the vertical direction is secured, and the beam can be reliably reinforced with respect to the load. In addition, since the main body is prevented from protruding from the inside of the gap between the beams, the reinforcing member does not interfere with face materials such as ceiling material, floor material, wall material, etc. As a result, the reinforcing member can be accommodated, so that the type and number of members constituting the building unit do not increase and the member management becomes easy.

In the above, a cross-shaped gap is formed between the lower beam of the upper-floor building unit and the upper beam of the lower-floor building unit. With a body that fits inside,
It is preferable that the width is substantially the same as the horizontal space between the beams to be reinforced. By doing so, the reinforcing member is sandwiched between the beams arranged on both sides thereof,
Since the beam can be fixed to the beam, the beam can be reinforced against external forces in the horizontal direction by the reinforcing member.In addition, since the beam is housed inside the cross-shaped gap, a protrusion is provided on the side surface of the reinforcing member. It is possible to lock to the beams arranged on both sides thereof, and by simply arranging the main body of the reinforcing member between the upper beams of the lower floor building unit, the reinforcing member can be fixed in the horizontal direction, and the reinforcing member Mounting work becomes easy.

Mounting becomes easy.

Further, it is preferable that the main body has a height dimension substantially the same as that of the lower beam. By doing so, the maximum rigidity of the reinforcing member against the vertical load is ensured within a range where the reinforcing member does not interfere with the surface materials such as the ceiling material, the floor material, and the wall material, and the beam is reinforced against the load. It can be performed more reliably.

Preferably, the main body is formed of a square tubular member. In this way, even if the width of the main body whose height dimension is substantially the same as the beam back of the lower beam is enlarged, its weight does not increase significantly. For this reason, the spacing between beams of adjacent building units that are close to each other is wide, and is approximately the same size as the spacing between beams.
Even if the width of the main body is set, handling of the reinforcing member does not become troublesome, and the reinforcing member can be easily attached to the beam.

According to a second aspect of the present invention, a plurality of building units each having a frame formed by pillars and beams are vertically arranged, and a lower beam of an upper-floor building unit and an upper beam of a lower-floor building unit which are arranged in close proximity to each other. A beam reinforcing member of a unit building for reinforcement, wherein a gap is formed between the plurality of beams,

Wherein the horizontal extension has a cross-sectional shape extending in the horizontal direction and does not protrude from the inside of the gap. In the second aspect of the invention, since the cross-sectional shape of the main body extends in the vertical direction, the rigidity against the load in the vertical direction is ensured, the beam can be reliably reinforced, and the cross-section extending in the horizontal direction is provided. The horizontal extension having the shape sandwiches the horizontal extension between the lower beam of the upper-floor building unit and the upper beam of the lower-floor building unit, so that the reinforcing member can be easily attached. Here, since the horizontal extension is prevented from protruding from the inside of the gap between the beams, if the cross-sectional shape of the reinforcing member is, for example, L-shaped so that the main body is along the side surface of the beam, it is disposed on the outer wall portion. When reinforcing the beam with the reinforcing member, the reinforcing member does not interfere with the surface materials such as the ceiling material, the floor material, and the wall material, and the reinforcing member fits in the normal fitting of the site such as the ceiling, the floor, and the wall. Therefore, the type and number of members constituting the building unit do not increase, and member management becomes easy.
