In such a building structure, one or more through holes may be formed in the web portion of the beam in order to pass the pipes and wirings provided therein. In this case, as means for preventing the strength of the beam from decreasing, there are a reinforcing sleeve member (for example, refer to Patent Document 1) attached to the through hole, a reinforcing plate (for example, refer to Patent Document 2), and the like.

８４が損傷することがなくなるという効果がある。Patent Document 1 describes a beam penetrating sleeve 83 as shown in FIG. The beam penetrating sleeve 83 is formed by integrally molding a sleeve main body 80 and a flange 81 located on the outer peripheral portion of the sleeve main body 80 with a material capable of being welded to the beam 82.
The thickness of the sleeve body 8 is at least on the inner peripheral surface side.
It is formed so as to gradually increase in thickness from both ends of 0 toward the intersection between the sleeve body 80 and the flange 81. With such a configuration, even if the pipe 84 is inserted in an oblique direction, there is an effect that the end of the beam penetration sleeve 83 is not contacted and the pipe 84 is not damaged.

い補強部材が求められている。However, since the beam penetrating sleeve 83 described in Patent Document 1 is a tubular member slightly shorter than the width of the flange portion 85 of the beam 82, it is formed by adjusting the wall thickness. There is also a limit to the amount of change in the inner diameter that can be made, and the insertion angle of the beam penetration sleeve 83 is also limited. Therefore, there is a demand for a reinforcing member having a high degree of freedom in attaching the pipe 84.

置に形成したいという要請がある。On the other hand, as represented by recent intelligent buildings, the facility functions of building structures have become complicated,
Furthermore, it is necessary to consider that the building to be designed will function sufficiently in the future in terms of building plans and building equipment. For this reason, it is desirable that various pipes and wirings inside the building structure are concentrated in a region close to the pillar in the beam-column joint structure, in other words, a region close to the joint end portion of the beam. There is a demand to form it at a position close to the column of the beam joint structure.

貫通孔を形成せざるを得ないのが実状である。However, the end of the beam that is close to the column is called a plasticized region, which is a region that absorbs seismic energy and undergoes a large deformation during a large earthquake. Generally, the installation of through-holes in the plasticized region is avoided because it causes a significant decrease in the strength of the joint structure and there is no reinforcing means that can compensate for it. Therefore, in reality, it is inevitable to form a through hole at a location away from the pillar, that is, a location away from the plasticized region of the beam, which is an inconvenient location from the viewpoint of piping and wiring.

It is an object to provide a beam reinforcing metal fitting that can be reinforced up to the strength and that enables a through hole to be installed in a plasticized region close to a beam-column joint, and a beam through hole reinforcing structure using the beam reinforcing metal fitting.

０．５倍〜１０．０倍としたことを特徴とする。In order to solve the above-mentioned problems, the beam reinforcing metal fitting of the present invention is a substantially ring-shaped beam reinforcing metal fitting fixed to the peripheral portion of a through hole formed in a beam by using fastening means. And a plurality of fastening means insertion holes provided in the peripheral portion of the through hole, which has a ring main body that can be fitted into the through hole, and a flange portion formed on the outer periphery of one side of the ring main body in the axial direction. A fastening means mounting hole having an arrangement corresponding to is provided in the flange portion, and the axial length of the ring body is set to 0.5 times to 10.0 times the wall thickness in the radial direction.

なくなり、取り付けの自由度が高まる。The stress generated in the peripheral portion of the through hole when an external force is applied to the beam becomes gradually smaller as it goes away from the web portion of the beam along the central axis of the through hole. To be a waste of. Therefore, the shape of the beam reinforcing metal fitting is substantially ring-shaped, and the axial length of the ring main body is 0.5 to 10.0 times (more preferably 0.5 to 5.0) the radial wall thickness. By restricting it to double, it is possible to reinforce the necessary strength even for through-holes of different sizes and to reinforce it to the required strength. Also, even if the pipe is inserted diagonally into the through-hole, Since it does not come into contact with the reinforcing metal member, the degree of freedom in mounting is increased.

る。In this case, the reason why the axial length of the ring body is 0.5 to 10.0 times the radial thickness is 0.
If it is less than 5 times, the strength becomes insufficient, and 1
This is because if it is greater than 0.0 times, the strength does not increase despite the increase in the length in the axial direction, and the material waste increases.

回避するとともに締結作業を迅速に行うことができる。It is desirable that the fastening means mounting holes are provided at 4 to 16 places. If there are less than four fastening means mounting holes, the load applied to one fastening means may become too large and the fastening means may break earlier than the beam reinforcing metal fittings. Since the work may be increased and the work may be delayed, 4 to 16 locations are preferable, whereby stress concentration of each fastening means can be avoided and the fastening work can be performed quickly.

It is also possible to set the time to 3.0 times. Here, the volume of the space portion can be obtained by multiplying the opening area of the through hole by the thickness of the web portion of the beam.

うな構成とすることによって、大きさが異なる貫通孔に
対して所定の強度で補強が行われる。The reason why the volume of the beam-reinforcing member is 1.0 to 3.0 times the volume of the space is that when the beam-reinforcing metal is less than 1.0 times, the beam having no through hole (hereinafter referred to as "no This is because the strength is smaller than that of the “hole beam”), and if it is more than 3.0 times, the strength is higher than that of the non-hole portion of the beam, resulting in excessive quality and too heavy weight. With such a configuration, the through holes having different sizes are reinforced with a predetermined strength.

とができる。It is also possible to gradually reduce the diameter of the outer peripheral portion of the ring main body toward the surface side without the flange portion. With this configuration, the work of fitting the ring body into the through hole can be facilitated and the work time can be shortened.

It is desirable that the length is half or less. When the beam reinforcing metal fitting having such a structure is fixed to the through hole of the beam by using a fastening means, it exerts an excellent reinforcing effect and has a strength equivalent to that of a beam having no through hole, that is, a so-called non-hole beam. Since it is obtained, it is possible to install the through hole in the plasticized region near the beam-column joint.

It is desirable to be 8 times or less. Beam formation refers to the dimension of the beam in the direction of gravity, for example, in the case of a beam made of H-shaped steel, the dimension from the surface of one flange portion to the surface of the other flange portion.

機能が低下するため、０．８倍以下が好適である。In the case of the conventional beam through-hole sleeve, the inner diameter of the through hole that can be formed in the beam is about 0.5 times the beam forming upper limit. Therefore, when there are many pipes and wirings, a plurality of through holes are provided. Although it was necessary, by setting the inner diameter of the ring body to 0.8 times or less of the beam formation, the size of the holes for piping and wiring can be up to 0.8 times that of the beam formation without causing a decrease in the strength of the beam. Since the size can be increased, it is not necessary to provide a plurality of through holes, and the number of steps can be reduced. In addition,
If the inner diameter of the ring main body exceeds 0.8 times the beam formation, the beam reinforcing function deteriorates, so 0.8 times or less is preferable.

It is also possible to provide a dowel pinching surface for pinching the dowel with the beam. The dowel is a member having a plurality of protrusions, and since it has an action of increasing the frictional force between the flange and the beam by sandwiching it between the flange and the beam, it resists the shearing force applied to the fastening means. Demonstrate the enhancing function.

It is characterized in that the distance from the joint position of the column and the beam to the axis of the beam reinforcing metal fitting is not more than twice the beam formation of the beam. With this structure, the through holes formed in the beam for passing various pipes and wirings inside the building structure can be arranged at a position close to the column of the beam-column joint structure. Therefore, it is possible to consolidate piping and wiring, which is convenient in designing a building, and the workability of wiring and piping is also greatly improved.
