In the illustrated example, an unattended store where an automatic teller machine (ATM) is installed is shown as a suitable application example of the earthquake-resistant structure building according to the present invention.

  The earthquake-resistant structure building according to the present invention includes a plurality of (six in the illustrated example) columns (2) erected on the upper part of the foundation (1), and a floor provided on the upper part of the foundation (1) ( 3) A building formed by forming an internal space (5) with a roof (33) provided on the top of the pillar (2) and a wall body (4) provided on the outside of the pillar (2). It is a thing.

  The foundation (1) is a concrete foundation provided on top of a granite (6) laid in the ground (G). This foundation (1) can be appropriately set in number and form depending on the size of the building to be constructed, and may be any of an independent foundation, a cloth foundation, and a solid foundation.

  In the illustrated example, the floor (3) is formed from dirt concrete placed on top of the foundation (1), but in a horizontal direction so as to connect the columns (2) erected on the foundation (1). It is also possible to adopt other configurations such as a configuration in which a steel plate is spread over and a floor plate is laid on the upper portion thereof, or a configuration in which a floor plate is laid on an upper portion of a beam connected to a foundation provided on the foundation (1). In addition, the structure of these floors (3) is employable similarly also about other embodiment mentioned later.

The column (2) is formed of a square tube-shaped steel material, and an anchor bolt (7) is inserted through the column (2). This anchor bolt (7) penetrates the inside of the pillar (2), the floor (3) and the foundation (1), and its lower end is buried deep in the ground.
In the present invention, the anchor bolt (7) can be divided into a plurality of members in the vertical direction in accordance with the length of the floor upper portion (referred to as the upward extending portion). For example, in the example shown in FIG. 3 to be described later, the upper member and the lower member are connected by the coupler (15).

In the present invention, the length of the portion (fixing portion) (7a) embedded in the ground of the anchor bolt (7) is at least the length reaching the support layer (stable layer) of the ground.
In the present invention, the anchor bolt (7) is driven through the inside of the pillar (2), the floor (3) and the foundation (1) to the support layer deep in the ground. Excellent earthquake resistance can be obtained.

The lower end of the anchor bolt (7) may be a straight one as shown in the figure, but a U-turn anchor curved in a J shape may be used. By using the U-turn anchor, it is possible to further improve the earthquake resistance.
A male screw is formed on the outer peripheral surface of at least the upper end of the anchor bolt (7), and a nut (8) is screwed to the male screw, and the nut (8) is screwed through the spacer (9). The floor (3) and foundation (1) are connected to anchor bolts (7).

Also, the inside of the pillar (2) is filled with mortar or concrete, whereby the anchor bolt (7) is fixedly integrated in the pillar (2), and extremely excellent earthquake resistance is exhibited.
In the present invention, after the anchor bolt (7) is driven into the ground, the nut (8) is strongly tightened, and the pressing force is applied to the top surface of the mortar or concrete filled in the column via the spacer (9). Is applied to the anchor bolt (7) in the vertical upward direction. As a result, the anchor bolt (7) exerts a great anchor effect, thereby making it possible to obtain very excellent earthquake resistance.

  In addition, the present invention has the structure as described above, and the pillar (2) is firmly fixed to the ground. For example, cash such as an automatic teller machine (CD) and an automatic teller machine (ATM) is provided. When it is applied to an unmanned store in which a device that handles the equipment is installed, it is possible to prevent theft that destroys the store by using heavy equipment such as a power shovel, which is frequently occurring in recent years.

FIG. 3 is an elevation view showing a second embodiment of the earthquake-resistant structure building according to the present invention.
In this second embodiment, as shown in the drawing, the upper end portion of the anchor bolt (7) is further extended upward, and the anchor bolt (7) is inserted over substantially the entire length inside the column (2). ing. In this case, the upper end portion of the anchor bolt (7) may be stopped inside the column (2) as shown, but it protrudes from the upper end portion of the column (2) and the nut (8) is screwed in this protruding portion. You can also wear it.
In either case, after the anchor bolt (7) is driven into the ground, the nut (8) is strongly tightened to apply a vertical upward tension to the anchor bolt (7).

Further, in the present invention, as a third embodiment, the anchor bolt (7) is not passed through the pillar (2), but is passed through the foundation (1) at a position different from the standing position of the pillar (2). It is also possible to adopt a configuration for driving in.
FIG. 4A is an elevation view when such a configuration is adopted, and FIG. 4B is a plan view thereof. In these figures, only the portion where the anchor bolt (7) of the building is arranged is extracted and shown.

In the example shown in FIG. 4, the anchor bolt (7) is driven into the ground so as to penetrate the floor (3) and the foundation (1) at a position close to the pillar (2).
Specifically, the foundation (1) formed in a frame shape along the outline of the building is extended inward at a position close to the pillar (2), and the anchor is penetrated through the extended portion. Bolt (7) is installed. Then, the nut (8) is screwed onto the male screw formed on the upper end portion of the anchor bolt (7) protruding from the extending portion of the foundation (1), and the spacer (9) is attached by screwing the nut (8). The floor (3) and the foundation (1) are connected to the anchor bolt (7).
In this case as well, after the anchor bolt (7) is driven into the ground, the nut (8) is strongly tightened to apply vertical tension to the anchor bolt (7).

  The anchor bolt (7) in the earthquake-resistant structure building according to the present invention only has to be placed in the ground through the foundation (1) and provided with a vertical upward tension. The placement position is not particularly limited. That is, the inside of the pillar (2) may be penetrated, may be provided close to the outside of the pillar (2), may be provided outside the internal space (5) of the building, It is also possible to provide in the space (5).

In the earthquake-resistant structure building according to the present invention described above, a plurality of reinforcing members (10) are installed between adjacent columns (2) so as to connect these columns. These reinforcing materials (10) are made of a high-strength material such as channel steel.
In the example shown in the drawing, the reinforcing member (10) is installed in an X-shaped cross shape. However, the reinforcing member (10) may be cross-shaped, or a plurality of reinforcing members may be arranged in parallel in the horizontal direction. It is good also as an erected form.
In the case of adopting a cross-shaped configuration, for the longitudinal reinforcement (10), between the upper beam and the lower beam provided at the lower part of the roof and the lower part of the floor so as to connect the columns (2). Just build it.

  By connecting the columns (2) with such a reinforcing material (10), even if the wall body (4) made of concrete or the like is destroyed by an external force, the reinforcing material (10) remains and the internal It becomes impossible to carry out large-sized devices and the like, and an unmanned store with extremely high crime prevention properties can be obtained that can prevent theft using heavy equipment such as a power shovel that has frequently occurred in recent years.

As shown in the figure, an unmanned store where cash handling devices such as an automatic teller machine (CD) and an automatic teller machine (ATM) are installed usually has an internal space (5) of the store by a partition wall (12). It is divided into a section (5a) where customers on the front side of (11) enter and exit and a section (5b) where workers on the back side of the apparatus (11) enter and exit.
In such a case, the reinforcing material (10) may be installed around both the compartments (5a) and (5b), but either one of them, for example, the compartment (5b) on the back side of the device (11) as shown in the figure. It is good also as a structure which lays a reinforcing material (10) only on.

In the present invention, a configuration in which a vibration sensor (not shown) for detecting the vibration of the column (2) is provided can be preferably employed.
Such a vibration sensor may be directly attached to the column (2), or may be attached to the foundation (1) or the reinforcing material (10) to indirectly detect the vibration of the column.
Theft by a method that destroys an unmanned store with cash handling equipment by using a structure that generates a warning sound when vibration is detected by a vibration sensor or that is reported to a security company. Can be detected early and prevented.

  The earthquake-resistant structure building of the above embodiment can be most suitably applied to an unmanned store in which a device for handling cash such as a CD or ATM as shown in the figure is installed, but the applicable building is not necessarily limited to this. The present invention is not limited and can be applied to other types of stores and ordinary private houses.

FIG. 5 is a partial elevation view showing the main part of the fourth embodiment of the seismic structure building according to the present invention, FIG. 6 is a plan view of the ceiling part, and FIG. FIG. This fourth embodiment can be suitably applied to, for example, a wooden two-story building.
In the structure of the fourth embodiment, as in the third embodiment, the anchor bolt (7) does not penetrate through the inside of the pillar (2), that is, at the position different from the standing position of the pillar (2) (1 ) Is driven through to the ground support layer.
Then, the nut (8) is screwed onto the male screw formed on the anchor bolt (7), and the floor (3) and the foundation (1) are anchored to the anchor bolt via the spacer (9) by screwing of the nut (8). By connecting with (7) and tightening the nut (8) strongly, vertical tension is applied to the anchor bolt (7).

The anchor bolt (7) extends upward to the ceiling in parallel with the pillar (2) at a position near the pillar (2).
The anchor bolt (7) is composed of a plurality of members connected in the vertical direction by the coupler (15) in the upper floor portion (upward extending portion). It penetrates the beam (13) between the floors and the beam (14) on the ceiling. In addition, the upper extension part of this anchor bolt (7) is made into the steel rod by which the screw was engraved on the outer surface.

  The upward extension part of the anchor bolt (7) is fixed to the neighboring pillar (2) at a predetermined interval. The fixed interval is preferably a constant interval, but it is not always necessary to provide all the fixed portions at the same interval. Also, the number of fixed locations is not particularly limited, and can be set to any number of 1 or more, but about 3 to 10 locations per floor from the point of balance between seismic strength and workability. It is preferable that

Furthermore, the upward extending part of the anchor bolt (7) is also fixed to the beams (13) (14). The fixing method is not particularly limited, but in the illustrated example, a fixing method by tightening the nut (17) is used. That is, on the upper surface and the lower surface of the beams (13) and (14), the nut (17) screwed to the outer surface of the upward extending portion is fastened to the beam via the washer (16).
As described above, since the upward extending portion of the anchor bolt (7) driven deep into the ground is fixed to both the column and the beam, it is possible to exhibit extremely excellent earthquake resistance.

Moreover, although it does not specifically limit about the fixing method of the upward extension part of the above-mentioned anchor bolt (7), and the pillar (2), In the example of illustration, two types of methods are used.
The first method is a method used on the upper surface of the beam (13) and the lower surface of the beam (14). In this method, a wing plate bolt (18) as shown in FIG. 8 is used, and a bent portion (18a) formed on one side thereof is sandwiched between a nut (17) and a washer (16), and on the other side. The formed male screw portion (18b) is penetrated at right angles to the column (2) and the other end portion is exposed to the outside of the column (2), and the nut (20) is connected to the other end portion through a washer (19). ).
In this first method, in order to prevent the wood forming the beams (13) and (14) from breaking, a band (24) made of rubber or the like is wound around the beam as shown in FIG. It is also possible to adopt a structure that tightens.

The second method is a method used at a position away from the beam. In this method, a fixture (21) shown in FIG. 10 and a spacer (22) shown in FIG. 11 are used.
FIG. 10 shows a state in which the fixing bracket (21) is opened, (a) is a front view of the opened state viewed from the inner surface side, and (b) is a bottom view thereof. The fixing bracket (21) has a structure in which two members are pivotally mounted via a hinge so as to be openable and closable. A penetrating through hole (21b) is provided.
FIG. 11A is a front view of the spacer (22), and FIG. 11B is a plan view thereof. The spacer (22) is composed of a pair of right-angled triangular blocks having a long hole through hole (22a) and is used so that the inclined surfaces face each other.

The fixing method using these fixing brackets (21) and spacers (22) is as follows.
First, the fixing bracket (21) is closed and screwed into an appropriate position of the upward extension portion of the anchor bolt (7). Next, a spacer (22) is interposed in the gap between the fixture (21) and the column (2). At this time, the thickness can be easily adjusted by changing the relative position of the pair of spacers (22). Finally, the bolt (23) is inserted into the through hole (21b) and the long hole through hole (22a), and the tip thereof is screwed to the column (2). Thereby, the column (2) and the anchor bolt (7) are fixed.

However, the above-described fixing method is merely an example, and the specific method is not limited to the above-described method, and the above-described feather plate bolts, fixing metal fittings, and spacers are not necessarily used.
In short, the first method may be a method of fixing the anchor bolt and the column using the fixing portion of the beam and the anchor bolt at the position of the upper surface or the lower surface of the beam. Any method may be used as long as the anchor bolt and the pillar are fixed at a position away from the center. For example, in the second method, a piece of wood processed on site can be used as a spacer.

In the fourth embodiment, the upper ends of the anchor bolts (7) are connected to each other at the ceiling as shown in FIG.
In the illustrated example, four anchor bolts (7) are provided so as to follow the pillars erected at the four corners of the rectangular structure in plan view. These four anchor bolts are connected to the connecting rod (25) arranged on the diagonal line and the connecting rod (26) arranged along the beam (14) by using any fixing means such as welding. It is connected.
Thus, by connecting the anchor bolts fixed to the pillars, the earthquake resistance of the building can be further improved.

In this way, when the upper ends of the plurality of anchor bolts (7) provided along the pillar (2) are connected at the ceiling, the anchor bolt itself forms a framework of the building.
Therefore, when creating the foundation of the building, it is also possible to simultaneously form a framework of the building with anchor bolts and construct the building on the foundation according to the formed framework. In this case, in order to give rigidity to the anchor bolt, for example, the entire anchor bolt (7) can be formed of a steel square tube.

In FIG. 7, circles and triangles indicate portions where the anchor bolt (7) and the building are fixed, circles indicate portions that are fixed by the tightening force of the nuts, and triangles indicate that the bolts are screwed. The part which is fixed by is shown. Further, (27) is a drilling hole, and the depth of the drilling hole (27) is determined by the soil quality.
The anchor bolt (7) can be fixed by injecting mortar into the hole (27). At this time, as shown in FIG. 12, a cylindrical wire mesh (28) is formed in the hole (27). If the mortar is put in, the injected mortar (29) can be prevented from escaping into the ground.

FIG. 7 shows a state where the anchor bolt (7) is driven through the foundation (1) at a position other than the position near the pillar (2).
The anchor bolts (7) at these positions do not need to be driven to the ground support layer, and even if they are driven to a relatively shallow position as shown in the figure, the earthquake resistance can be sufficiently enhanced. It is not impeded to drive in.
The anchor bolts (7) at these positions have the same length as that of the third embodiment and do not reach the ceiling. Although not shown, a nut is screwed onto a male screw formed at the upper end portion of the anchor bolt (7), and the floor (3) and the foundation (1) are anchored to the anchor bolt via a spacer by screwing the nut. By connecting with (7) and tightening the nut strongly, vertical tension is applied to the anchor bolt (7).
Thus, even at positions other than the position near the pillar (2), it is possible to further improve the earthquake resistance by adopting a structure in which the anchor bolt (7) is driven through the foundation (1) into the ground. It becomes.

  Moreover, in the said 4th embodiment, it is also possible to take the structure which pierces the pillar (2) and penetrates the inside of the upward extension part (floor part) of an anchor bolt (7). That is, in the present invention, the anchor bolt (7) can be arranged inside the column (2) in all the embodiments, and the anchor bolt (7) can be hidden by adopting such a form. It looks good and looks better.

  The present invention is used for imparting high earthquake resistance to a relatively small building such as a wooden building such as a private house or an unmanned store where an ATM or the like is installed.
