Description

The present invention relates to a structure system.

External inputs such as earthquakes act on the bases of building columns, which are subjected to forces (rotational forces) that tend to topple the columns, as well as shear forces in a direction perpendicular to the longitudinal direction of the columns.
Patent Document 1 discloses a technology in which, in order to ensure the resistance (shear resistance) to shear forces applied to the column base, the metal fittings at the intersections between the columns and beams are not glued to the concrete slab surface, but rather a movement restraint member such as a plate that bears the force is provided separately from the metal fittings.
Furthermore, Patent Document 2 discloses an exposed-type column base fixing structure that is effective when applied to steel columns that serve as corner columns or side columns of a steel-framed building. In the exposed-type column base fixing structure, a horizontal anchor is joined to a base plate fixed to the lower end of a steel column located at an installation location where the covering concrete does not spread horizontally in at least one direction, in the direction opposite to the direction in which the covering concrete does not spread horizontally, and is embedded in the covering concrete.

First Embodiment
A structure system according to one embodiment of the present invention will be described below with reference to the drawings. The structure system includes a structure 100 and a reinforcement structure. A plurality of structures 100 are provided in a building such as a logistics facility. The reinforcement structure includes a shear force reinforcement section 200. The shear force reinforcement section 200 is provided adjacent to the structure 100. The shear force reinforcement section 200 reinforces the structure 100. The structure 100 and the shear force reinforcement section 200 each have the following configuration.

In this embodiment, the structure 100 is embedded in a concrete slab CS, for example, as shown in FIG. 1. In this embodiment, the structure 100 being embedded in a concrete slab CS includes a state in which only a portion of the structure 100 is embedded in the concrete slab CS. Specifically, for example, in the structure 100 shown in FIG. 1, the gusset plate 41 (described later) is embedded inside the concrete slab CS, but the gusset plate 41 does not have to be embedded in the concrete slab CS.

The structure 100 has, for example, the following configuration in order to ensure the earthquake resistance of the building.
As shown in FIGS. 1 and 2 , the structure 100 includes a substructure 10, a base plate 20, a column member 30, and a brace 40.
The substructure 10 is, for example, a concrete structure such as a foundation member, a footing, or a foundation column of a building. The substructure 10 is, for example, a concrete slab CS. The components described below are disposed in the substructure 10. The components described below are disposed, for example, inside the substructure 10. In this embodiment, this state includes the structure 100 being embedded in the concrete slab CS.

The base plate 20 is fixed to the lower structure 10. Specifically, the base plate 20 is fixed to the lower structure 10 by a plurality of first anchor bolts B1, for example, as shown in FIG. 1. The number of the first anchor bolts B1 is appropriately determined in consideration of the size of the base plate 20, the required fastening force, etc. The base plate 20 is, for example, a steel plate. The base plate 20 may be, for example, another plate-shaped member. The base plate 20 is, for example, a square shape as shown in FIG. 2. The base plate 20 may be a circle, an ellipse, or another shape. The lower end of the column member 30 is connected to the base plate 20. Note that a rib (not shown) may be provided at the connection portion between the base plate 20 and the column member 30 to reinforce the connection portion between the base plate 20 and the column member 30.

The column members 30 form the framework of the building. As shown in Fig. 1, the column members 30 are provided on the base plate 20. Specifically, the column members 30 are fixed to the base plate 20 by, for example, welding. In this way, the column members 30 are fixed to the substructure 10 via the base plate 20.
The column member 30 is formed of, for example, a steel material. The column member 30 may be formed of, for example, other materials. The column member 30 has, for example, a rectangular tube shape. The column member 30 may have, for example, a cylindrical shape or another shape.
For example, a pin base or a normal base is preferably used as the column member 30. The column member 30 may have any other structure.

The brace 40 is a seismic reinforcement member for a building. The brace 40 is attached to the base plate 20. For example, a buckling restraint brace such as Unbonded Brace (registered trademark) manufactured by Nippon Steel Engineering Co., Ltd. is used for the brace 40. The brace 40 is attached, for example, to a predetermined side of the column member 30 and the base plate 20. The predetermined side is, for example, the side facing the column members 30 adjacent to each other in the building. The brace 40 is attached diagonally in the building as shown in FIG. 1. For example, one end of the brace 40 is connected to the base plate 20 via a gusset plate 41. The other end of the brace 40 is connected, for example, to the upper part of the adjacent column member 30.

The shear force reinforcement part 200 is fixed to the substructure 10. The shear force reinforcement part 200 is fixed to the substructure 10 by, for example, a plurality of second anchor bolts B2. In this embodiment, the shear force reinforcement part 200 includes, for example, a shear force reinforcement plate 210 and a plurality of second anchor bolts B2. In this case, the shear force reinforcement plate 210 is fixed to the substructure 10 by each of the plurality of second anchor bolts B2. The plurality of second anchor bolts B2 are arranged, for example, in the direction in which the brace 40 extends when viewed along the vertical direction. As shown in Figures 3 to 6, for example, a rib 220 is provided at the end of the shear force reinforcement plate 210, which is the end on the side of the column member 30. The rib 220 transmits the shear force SF generated in the structure 100 to the plurality of second anchor bolts B2 (details will be described later).

As shown in FIG. 8, the shear force reinforcement section 200 resists only the shear force SF generated in the structure 100. Here, when an external force is applied to the building due to an earthquake or the like, the base plate 20 fixed to the substructure 10 may be pushed or pulled by the brace 40 along the axial direction of the brace 40. At this time, the force along the axial direction of the brace 40 is resolved into the vertical and horizontal directions as shown in FIG. 7 and FIG. 8. The force along the vertical direction is applied as a compressive force CF or a tensile force TF to the base plate 20 and the first anchor bolt B1 that fixes the base plate 20 to the substructure 10. The force along the horizontal direction is applied as a shear force SF to the base plate 20 and the first anchor bolt B1 that fixes the base plate 20 to the substructure 10.

When the base plate 20 is pushed along the axial direction of the brace 40, as shown in FIG. 7, for example, a force that tries to topple the column member 30 is generated, that is, a rotational force RF with the lower end of the column member 30 as the axis of rotation. The force along the axial direction of the brace 40 is resolved into a compressive force CF that presses the base plate 20 vertically downward toward the substructure 10, and a shear force SF that acts horizontally toward the side of the base plate 20 opposite the specified side on which the brace 40 is provided. The above-mentioned rotational force RF can be countered by the first anchor bolt B1 that secures the base plate 20 to the substructure 10.

In addition to the compressive force CF acting as described above, the base plate 20 is also subjected to a compressive force CF due to the weight of the column member 30 and the weight (load) of the structure supported by the column member 30. At this time, a sufficient frictional force FF is generated between the lower structure 10 and the base plate 20. This frictional force FF is able to resist the shear force SF.

When the base plate 20 is pulled along the axial direction of the brace 40, as shown in FIG. 8, a rotational force RF is generated in the opposite direction to when the base plate 20 is pushed along the axial direction of the brace 40. The force along the axial direction of the brace 40 is resolved into a tensile force TF that acts to peel the base plate 20 vertically upward from the substructure 10, and a shear force SF that acts horizontally toward the specified side of the base plate 20 on which the brace 40 is provided. The above-mentioned rotational force RF can be countered by the first anchor bolt B1 that secures the base plate 20 to the substructure 10.

The tensile force TF acting on the base plate 20 as described above is offset by the weight of the column member 30. Therefore, as shown in FIG. 8, the vertical force applied to the base plate 20 is the compressive force CF on the base plate 20 due to the weight of the column member 30 minus the tensile force TF described above, and is applied to the base plate 20 as a compressive force CF. At this time, since a sufficient friction force FF is not generated between the lower structure 10 and the base plate 20, it becomes difficult to resist the shear force SF using only the first anchor bolt B1 that secures the base plate 20.

For this reason, the shear force reinforcement section 200 is provided on a predetermined side of the base plate 20 on which the brace 40 is provided as described above. This allows the shear force reinforcement section 200 to resist the shear force SF that occurs when the base plate 20 is pulled along the axial direction of the brace 40. In this embodiment, the shear force reinforcement section 200 is arranged as follows, so that it can resist only the shear force SF that occurs in the structure 100.

That is, the shear force reinforcement section 200 is arranged so as to overlap the base plate 20 when viewed horizontally from a predetermined side of the base plate 20. That is, the shear force reinforcement section 200 is arranged so that the thickness of the base plate 20 is included within the interior of the height direction of the shear force reinforcement section 200 including the rib 220.

Specifically, for example, as shown in Figures 3 to 6, the shear force reinforcing plate 210 is arranged so that the shear force receiving surface 210s faces the horizontal end of the base plate 20. The shear force receiving surface 210s is a surface that receives the shear force SF transmitted from the base plate 20. In this embodiment, the shear force receiving surface 210s is a surface of the rib 220 that faces the base plate 20. In the shear force reinforcing plate 210, the rib 220 is provided to increase the shear force receiving surface 210s.

By providing the rib 220, for example, it is possible to smoothly transmit the shear force SF to the shear force reinforcing plate 210. For example, by increasing the area of contact with the base plate 20, it is possible to alleviate the stress of the filler G (described later) filled between the base plate 20 and the shear force reinforcing plate 210. For example, it is possible to suppress the thickness of the shear force reinforcing plate 210.
In addition, if the base plate 20 and the shear force reinforcement plate 210 have the same thickness and there is no step, the rib 220 does not need to be provided.

In order to transmit the horizontal force applied to the base plate 20 to the shear force reinforcement section 200, it is preferable that the structure between the shear force reinforcement section 200 and the base plate 20 be, for example, one of the following two forms.
As a first form of the structure between the shear force reinforcement portion 200 and the base plate 20, as shown in Fig. 3 and Fig. 4, a gap CL is provided between the shear force reinforcement plate 210 and the base plate 20. The gap CL between the shear force reinforcement plate 210 and the base plate 20 is filled with a filler material G. For example, non-shrink mortar is used as the filler material G.

As a second embodiment of the structure between the shear force reinforcement portion 200 and the base plate 20, as shown in FIGS. 5 and 6, a shear force reinforcement plate 210 abuts against the base plate 20.
Here, when the surface of the base plate 20 facing the shear force reinforcement plate 210 moves upward, a force may act to flip the shear force reinforcement plate 210 up from the lower structure 10. In this embodiment, the contact surface between the shear force reinforcement plate 210 and the base plate 20 is vertical, for example, as shown in Figures 3 and 5. Alternatively, the contact surface between the shear force reinforcement plate 210 and the base plate 20 is inclined so that the end face of the base plate 20 is located on the upper side, as shown in Figures 4 and 6, for example, when viewed from a direction perpendicular to the direction in which the shear force SF is generated and perpendicular to the vertical direction. This prevents a force from acting on the shear force reinforcement part 200 by the base plate 20 to flip it up from the lower structure 10 as described above.

The above-described structure allows the shear force SF generated in the structure 100 to be transmitted to the second anchor bolts B2 that secure the shear force reinforcement plate 210 to the substructure 10. Specifically, the horizontal force applied to the base plate 20 via the brace 40 is transmitted to the shear force receiving surface 210s of the rib 220.

In this embodiment, a template T is used to determine the positions of each of the multiple first anchor bolts B1 and the multiple second anchor bolts B2, as shown in FIG. 16. The template T is, for example, a plate-like member having holes aligned with the positions of the first anchor bolts B1 or the second anchor bolts B2. The template T includes, for example, a first template T1 for the base plate 20 and a second template T2 for the shear force reinforcement section 200. The first template T1 and the second template T2 may be, for example, integrated. Furthermore, the integrated template T as described above may be divisible and connectable.

In this embodiment, the first template T1 for the first anchor bolt B1, i.e., for the base plate 20, and the second template T2 for the second anchor bolt B2, i.e., for the shear force reinforcement section 200, are provided independently. The first template T1 and the second template T2 are fixed by a removable connecting member TC to fix their respective positional relationship, as shown in Fig. 16. When reinforcing bars are arranged in the concrete slab CS, the connecting member TC can be removed in order to place the hoop reinforcement H around the first anchor bolt B1. By providing such a connecting member, the positional relationship between the first anchor bolt B1 and the second anchor bolt B2 can be secured.
The template T has the function of ensuring the positional accuracy of the first anchor bolt B1 and the second anchor bolt B2 by determining the positions of the first anchor bolt B1 and the second anchor bolt B2 as described above, and also making it possible to position the hoop reinforcement H surrounding the first anchor bolt B1.

As described above, the structure 100 according to this embodiment includes the shear force reinforcement part 200 that resists only the shear force SF generated in the structure 100. This can improve the shear resistance of the structure 100. Here, if it is desired to improve the shear resistance of the structure 100 by using the base plate 20, it is necessary to increase the size of the base plate 20, increase the number of the first anchor bolts B1, increase the diameter of the first anchor bolts B1, or all of these. In this case, the rigidity against the force that tries to turn up the base plate 20 becomes higher than necessary. That is, for example, when the structure 100 includes the column member 30, that is, when the column member 30 is attached to the base plate 20, the rigidity (rotational rigidity of the joint) against the force (rotational force RF) that acts to topple the column member 30 becomes higher than necessary. This causes, for example, the cost of the base plate 20 to be higher than necessary. Furthermore, for example, when the structure 100 is equipped with a brace 40, that is, when the brace 40 is attached to the base plate 20, the force applied to the column member 30 is not sufficiently transmitted to the brace 40, which causes the performance of the brace 40 to be underutilized. Also, there are no existing column base products that can withstand a large shear force SF, and a separate design may be required.

By providing the shear force reinforcement portion 200, for example, the base plate 20 can be structured in consideration of only the rotational rigidity of the joint. Therefore, the shear resistance of the structure 100 can be improved without affecting the rotational rigidity of the structure 100. Therefore, for example, it is possible to prevent the base plate 20 from being made larger than necessary, or to prevent the number of first anchor bolts B1 from being increased more than necessary.
Furthermore, for example, when the structure 100 includes the column member 30 and the brace 40, that is, when the column member 30 and the brace 40 are attached to the base plate 20, the force applied to the column member 30 can be sufficiently transmitted to the brace 40. Thus, the performance of the brace 40 can be fully utilized. Furthermore, the stress borne by the first anchor bolts B1 can be suppressed without increasing the number of first anchor bolts B1 provided on the base plate 20. Thus, the bending resistance of the first anchor bolts B1 provided on the base plate 20 can be ensured.

Here, for example, when the column member 30 and the brace 40 are provided on the base plate 20, the direction of the shear force SF generated in the structure 100 is, for example, along the direction in which the brace 40 extends when viewed vertically. For this reason, when the base plate 20 is designed to have a structure that takes shear resistance into consideration, the rotational rigidity is not horizontally symmetrical because the first anchor bolts B1, etc. are added in the direction in which the brace 40 is attached, and the base plate 20 is expanded, and the structure of the base plate 20 becomes complex. The structure 100 is provided with a shear force reinforcement section 200, and the base plate 20 can be designed to have a structure that takes into consideration only the rotational rigidity of the joints, so that the rotational rigidity of the joints of the structure 100 can be made symmetrical in the left-right direction. This makes it easier to design the structure 100.

The structure 100 further includes a brace 40, which is a seismic reinforcement member. The brace 40 is attached to the base plate 20. This can improve the strength of the structure 100 against earthquakes and the like, and suppress horizontal displacement of the structure 100, which is expected to improve the strength of the entire building and suppress horizontal displacement.

The structure 100 further includes a column member 30. The column member 30 is attached to the base plate 20. This allows the structure to be designed to handle the resultant force of the vertical force from the brace 40 and the vertical force supported by the column, simplifying the joints and the design.

The brace 40 is provided on a predetermined side of the column member 30 and the base plate 20. The shear force reinforcement section 200 is provided on the predetermined side of the base plate 20. In other words, the shear force reinforcement section 200 is provided in the direction in which the brace 40 is provided. This allows the shear force reinforcement section 200 to resist the shear force SF generated when the base plate 20 is pulled by the brace 40.

The shear force reinforcement section 200 also includes a compression anchor. By using a compression anchor, it is possible to transmit the shear force SF to the concrete section without inducing localized destruction of the concrete, and the configuration according to the present invention can be realized. Furthermore, construction costs can be reduced by using known reinforcing bars, etc., for the compression anchor.

The shear force reinforcement section 200 also includes a shear anchor. By using a known shear anchor as the shear force reinforcement section 200, it can be installed at a construction site or the like in the same way as an anchor bolt in the reinforced section, so the configuration according to the present invention can be realized without special design or development of new parts. Therefore, it is possible to suppress increases in costs.

In addition, the shear force reinforcement section 200 overlaps with the base plate 20 when viewed in the horizontal direction. This allows the shear force reinforcement section 200 to reliably resist the shear force SF generated in the base plate 20.

Here, if the shear force reinforcement portion 200 and the base plate 20 are in direct contact with each other, when a rotational force RF is applied to the base plate 20 from the column member 30, the shear force reinforcement portion 200 may be deformed by the base plate 20 in such a way that it is turned up.
A gap CL is provided between the shear force reinforcement portion 200 and the base plate 20. This makes it possible to suppress, for example, a force acting such that the shear force reinforcement portion 200 is turned up by the base plate 20. The gap CL between the shear force reinforcement portion 200 and the base plate 20 is filled with filler material G. This allows the structure 100 to have a structure in which the shear force reinforcement portion 200 resists only the shear force SF generated in the base plate 20. In addition, construction errors that occur between the shear force reinforcement portion 200 and the base plate 20 can be absorbed.

In addition, the shear force reinforcement section 200 abuts against the base plate 20. This further enhances the effect of the shear force reinforcement section 200 in adding shear resistance to the structure 100.

The shear force reinforcement section 200 also includes a plurality of second anchor bolts B2. This allows the second anchor bolts B2 to resist the shear force transmitted to the shear force reinforcement section 200. This makes it possible to more reliably impart shear resistance to the structure 100.

The structure 100 is also embedded in the concrete slab CS. This makes it possible to make at least a portion of the structure 100 invisible from the outside. This improves the design. Furthermore, for example, by embedding the first anchor bolt B1 inside the concrete slab CS, it is possible to increase the floor area that can be effectively used. Furthermore, by embedding the first anchor bolt B1 in the concrete slab CS, it is expected that the bearing resistance of the concrete slab CS will be added to the column member 30.

The contact surface between the shear force reinforcement section 200 and the base plate 20 is vertical or inclined so that the end face of the base plate 20 is located on the upper side. This reliably prevents the base plate 20 from exerting a force that would cause the shear force reinforcement section 200 to be turned up.

Second Embodiment
Next, a structure system according to a second embodiment of the present invention will be described with reference to FIGS.
In the second embodiment, the same components as those in the first embodiment are denoted by the same reference numerals, and their description will be omitted, with only the differences being described.

As shown in Figures 9 to 11, the structure system according to the second embodiment differs from the structure 100 in that it includes a compression anchor bolt 310 (compression anchor) and a stopper 320 as the second shear force reinforcement section 300. In this embodiment, the compression anchor bolt 310 needs to be located inside the concrete slab CS. In this embodiment, the column member 30 does not need to be located inside the concrete slab CS.

The compression anchor bolts 310 extend in the horizontal direction. Specifically, the compression anchor bolts 310 extend in the direction in which the braces 40 are provided, for example, when viewed in the vertical direction among the horizontal directions. The compression anchor bolts 310 are provided so that multiple compression anchor bolts 310 are arranged in parallel. The compression anchor bolts 310 resist only the shear force SF.

Each of the multiple compression anchor bolts 310 is embedded in, for example, poured concrete 330. The poured concrete 330 is cast so as to cover only the compression anchor bolts 310, for example, as shown in FIG. 9. The poured concrete 330 may be cast so as to cover not only the compression anchor bolts 310 but also each component of the structure 100, for example, as shown in FIG. 10.

The compression anchor bolt 310 has, for example, unevenness (not shown) on its surface. The unevenness on the compression anchor bolt 310 has, for example, a shape similar to that on the surface of a known deformed reinforcing bar or threaded reinforcing bar. When the compression anchor bolt 310 is embedded in the concrete 330, the unevenness engages with the concrete 330. As a result, the force transmitted to the compression anchor bolt 310 is gradually transmitted to the concrete 330. As a result, the compression anchor bolt 310 has the function of suppressing bearing failure of the concrete 330.

The stopper 320 is provided at the end of each of the multiple compression anchor bolts 310, that is, at the end on the side of the pillar member 30. As shown in FIG. 11, the stopper 320 is provided across the ends of the multiple compression anchor bolts 310. In other words, one stopper 320 is provided for each of the multiple compression anchor bolts 310. The stopper 320 may be, for example, divisible.

In order to transmit a horizontal force applied to the base plate 20 to the stopper 320, the structure between the stopper 320 and the base plate 20 may be, for example, one of the following two forms.
As a first embodiment of the structure between the stopper 320 and the base plate 20, as shown in Fig. 12, a gap CL is provided between the stopper 320 and the base plate 20. A filling material G is filled in the gap CL between the stopper 320 and the base plate 20.

For example, as shown in Figs. 11 and 12, a gap CL2 can be provided between the stopper 320 and the raised concrete 330. This allows the force applied to the stopper 320 to be transmitted to the compression anchor bolt 310. Specifically, the force applied to the stopper 320 can be transmitted to the raised concrete 330 via the adhesive force between the compression anchor bolt 310 and the concrete. At this time, by adjusting the size of the gap CL2, it is possible to control the size of the shear resistance force of the shear force reinforcement part 200, which is transmitted to the raised concrete 330 as a support pressure, and the size of the portion transmitted to the raised concrete 330 as the adhesive force of the compression anchor bolt 310. In this way, by dividing the mode of transmission to the raised concrete 330, it is possible to prevent destruction from concentrating on a part of the raised concrete 330 and losing its resistance force due to brittleness. Note that, as shown in Fig. 13, the gap CL2 does not have to be provided between the stopper 320 and the raised concrete 330.

The position of the compression anchor bolt 310 is preferably within the range of the thickness of the base plate 20 in front view, as shown in Fig. 17. In other words, it is not preferable that the position of the compression anchor bolt 310 is outside the range of the thickness of the base plate 20, as shown in Fig. 18, and it is preferable to take care to avoid such a state.
The position of the compression anchor bolt 310 is preferably within the range of the width of the base plate 20 in a plan view, as shown in FIG.

As a second embodiment of the structure between the stopper 320 and the base plate 20, the stopper 320 abuts against the base plate 20 as shown in FIG.
In this embodiment, the contact surface between the stopper 320 and the base plate 20 is similar to that in the first embodiment described above. That is, the contact surface between the stopper 320 and the base plate 20 is, for example, vertical. Alternatively, the contact surface between the stopper 320 and the base plate 20 may be inclined so that the end face of the base plate 20 is located on the upper side.
In the second embodiment of the structure between the stopper 320 and the base plate 20, a gap CL2 may be provided between the stopper 320 and the concrete 330 as shown in Fig. 14. Alternatively, the gap CL2 may not be provided between the stopper 320 and the concrete 330 as shown in Fig. 15.

With the above-described configuration, each of the multiple compression anchor bolts 310 abuts against the base plate 20 via the stopper 320. As a result, the stopper 320 transmits the horizontal force applied to the base plate 20 to the compression anchor bolt 310. In addition, each of the multiple compression anchor bolts 310 resists the shear force SF by abutting against the base plate 20 via the stopper 320.

The technical scope of the present invention is not limited to the above-described embodiment, and various modifications can be made without departing from the spirit of the present invention.
For example, in the present embodiment, the structure 100 is described as being embedded in the concrete slab CS, but it does not have to be embedded. In other words, the components located above and beyond the base plate 20 and the shear force reinforcement 200 may be exposed above the substructure 10.
Further, the configuration for transmitting the horizontal force applied to the base plate 20 to the shear force reinforcement portion 200 is not limited to the structure 100, and may be used, for example, in the middle of a foundation beam 400 on which a plurality of braces 40 are provided, as shown in Fig. 19. In this case, a plurality of shear force reinforcement portions 200 may be provided on the base plate 20.
Also, in the second embodiment, the second shear force reinforcement may include a shear anchor instead of a compression anchor.

In addition, the components in the above embodiment may be replaced with well-known components as appropriate without departing from the spirit of the present invention, and the above-mentioned modifications may be combined as appropriate.
