The structure joined in step 1 will be described.

[First Embodiment]
FIG. 12 shows a first embodiment of a structure based on the first floor of a wooden building.
In the structure according to the first embodiment, a gate-shaped shape including two pillars PT and one beam BM with respect to the concrete base BS by using two vertical metal joints 100 and two connecting hardwares 150. The framework is built. Then, a rectangular shape that is fitted to a gate-shaped frame using two tie-down hardware 200, four box-shaped hardware 250, one first shear metal 350, and one second shear metal 400. The panel PN is joined.

  In the center of the upper surface and the lower surface of the pillar PT, slits SL1 are formed, respectively, in which the connecting members 110 and the joining members 110 of the vertical material joining metal 100 can be fitted along the extending direction of the concrete foundation BS. In addition, small holes (not shown) for driving a drift pin into the through hole 150 </ b> A of the connection hardware 150 and the through hole 110 </ b> A of the joining member 110 are formed on one side surface of the pillar PT.

  In the center of the left and right side surfaces of the panel PN, slits SL2 into which the tie-down hardware 200 can be fitted are formed from the upper end to the lower end. Here, the upper end portion and the lower end portion of the slit SL2 of the panel PN are formed in a stepped shape whose width is wider than the center portion so that the bolt member 220 of the tie-down hardware 200 can be fitted. Moreover, the slit which can fit the joining member 430 of the 2nd shear metal 400 and the joining member 360 of the 1st shear metal 350 to the center of the upper surface and lower surface of the panel PN in the direction where the plate | board surface is extended, respectively. SL3 and slit SL4 are formed.

  Two slits SL5 into which the connecting hardware 150 can be fitted and a cylindrical member 420 of the second shearing hardware 400 can be fitted into a predetermined position on the lower surface of the beam BM along the direction in which the axis extends. Two circular holes CH1 are formed. Further, two through holes TH1 through which the shaft portion of the bolt member 220 of the tie-down hardware 200 can penetrate are formed at predetermined positions of the beam BM so as to penetrate from the upper surface to the lower surface.

  The tie-down hardware 200 is fitted into the slit SL2 of the panel PN, and is integrated by, for example, an adhesive. Here, when the through-hole 210A is formed in the base member 210 of the tie-down hardware 200, a drift pin is driven from one surface of the panel PN instead of an adhesive or the like, and the shaft portion passes through the through-hole 210A. By doing so, the panel PN and the tie-down hardware 200 can be integrated. Further, the joining member 430 of the second shear metal 400 is fitted into the slit SL3 of the panel PN, and a drift pin is driven from one surface of the panel PN, and the shaft portion is passed through the through-hole 430A. The two shear hardware 400 can be integrated. Note that the tie-down hardware 200 and the second shearing hardware 400 may be integrated with the panel PN when the structure is constructed.

  On the upper surface of the concrete foundation BS, an anchor bolt AB projecting upward from the upper surface, and a fastener FM including a flat washer, a spring washer and a double nut screwed to the tip end of the concrete base BS are shown. From one side to the left, the vertical metal joint 100, the box metal 250, the first shear metal 350, the box metal 250, and the vertical metal joint 100 are fastened in this order. That is, the vertical material joint metal 100, the box-shaped metal 250, and the first shear metal 350 are the upper surface of the concrete base BS with the through holes 122A, the through holes 250A, and the through holes 372A passing through the shaft portion of the anchor bolt AB. Are fastened by screwing a fastener FM to the shaft portion of the anchor bolt AB protruding from the bottom plate.

  The lower surface of the pillar PT is joined to the vertical metal joint 100 by fitting the joining member 110 into the slit SL1 formed on the lower face of the pillar PT. At this time, in order to ensure the joining of the pillar PT to the vertical material joining hardware 100, the drift pin is driven from one side face of the pillar PT, and the shaft portion penetrates the through hole 110A of the joining member 110.

  The lower surface of the panel PN in which the tie-down hardware 200 is integrated is joined to the box-shaped hardware 250 and the first shearing hardware 350. That is, the shaft portion of the bolt member 220 of the tie-down hardware 200 passes through the through hole 250A of the box-shaped hardware 250, and the fastener FM is screwed into the male screw 220A. Are joined. Further, the first shear metal 350 has a joint member 360 fitted in a slit SL4 formed on the lower surface of the panel PN, and a drift pin is driven from one surface of the panel PN, and the shaft portion penetrates the through hole 360A. By doing so, the lower surface of the panel PN is joined to the first shear metal 350.

  The lower surface of the beam BM is joined to the upper surfaces of the left and right pillars PT and the panel PN via the connecting hardware 150 and the second shearing hardware 400. That is, the connecting hardware 150 is fitted over the slit SL1 formed on the upper surface of the pillar PT and the slit SL5 formed on the lower face of the beam BM, and the drift pins are hit from one surface of the pillar PT and the beam BM, respectively. The shaft portion is inserted into the through hole 150 </ b> A of the connection hardware 150. Further, the cylindrical member 420 of the second shear metal 400 integrated with the panel PN is fitted in the circular hole CH1 of the beam BM. Further, the shaft portion of the bolt member 220 of the tie-down hardware 200 integrated with the panel PN is penetrated into the through hole TH1 of the beam BM, and the bolt member 220 protruding from the upper surface of the beam BM is formed on the bottom surface of the box-shaped hardware 250. The through-hole 250A is penetrated. A fastener FM is screwed onto the male screw 220A of the bolt member 220 protruding from the bottom plate of the box-shaped hardware 250.

  Note that when the fastener FM is tightened, the box-shaped hardware 250 has a larger plane than the bottom plate of the box-shaped hardware 250 between the box-shaped hardware 250 and the beam BM in order to prevent the box-shaped hardware 250 from entering the beam BM. For example, a plate (washer) PT made of a rectangular metal plate may be interposed. Further, the fastening of the tie-down hardware 200 to the beam BM is not limited to the box-shaped hardware 250, but may be performed only by the plate PT or the spacer hardware 300 in which a through hole is formed only on the bottom plate.

  According to the first embodiment of such a structure, when a horizontal force due to, for example, an earthquake or a typhoon acts on a gate-shaped frame composed of two pillars PT and beams BM, this tends to deform into a parallelogram. To do. When the gate-shaped frame is deformed, the rectangular panel PN is fitted into the frame, so that the pillar PT contacts the side surface of the panel PN, and the deformation can be suppressed. In this case, a shearing force extending in the axial direction of the beam BM acts between the upper surface of the panel PN and the beam BM. The shearing force is received by the cylindrical member 420 of the second shear metal 400, and the frame It can suppress that a deformation | transformation becomes large too much. Further, when a vertical load is applied to the portal frame, the cylindrical member 420 of the second shear metal 400 and the circular hole CH1 of the beam BM can be relatively displaced, so that the beam BM is moved to the panel PN. The acting load is cut off. For this reason, it is not necessary to support a load with the panel PN, and the structural design of the gate-shaped frame can be facilitated.

  When the gate-shaped frame causes parallelogram-like deformation, the concrete base BS and the beam BM arranged in parallel are separated from each other by coming into contact with the panel PN. However, since the concrete foundation BS and the beam BM are connected via the tie-down hardware 200 integrated with the panel PN, the relative displacement of the beam BM with respect to the concrete foundation BS is suppressed, and the concrete foundation BS and the beam BM are suppressed. Can be prevented from rising apart from each other. Note that the tie-down hardware 200 is not limited to the configuration in which the concrete foundation BS and the beam BM are connected, and, for example, connects two structural frames arranged in parallel, such as a base, a beam, two beams, and two columns. You can also.

  By the way, when a parallelogram-like deformation occurs in the gate-shaped frame by the action of the horizontal force, the displacement of the beam BM relative to the concrete foundation BS is suppressed by the tie-down hardware 200, so that it is positioned on the upper surface of the beam BM. There is a possibility that the box-shaped hardware 250 or the like will sink into the beam BM. In view of this, a reinforcing hardware 550 as shown in FIG. 13 is used to suppress the penetration of the box-shaped hardware 250 or the like into the beam BM.

  The reinforcing hardware 550 includes a first plate member 560 made of a rectangular metal plate in plan view, a cylindrical member 570 made of a metal cylinder, and a second plate member 580 made of a rectangular metal plate in plan view, A fastener FM. The first plate member 560 is formed with a through-hole 560A through which the shaft portion of the bolt member 220 of the tie-down hardware 200 can pass, and one side (short side) thereof is bent 90 ° downward. It has a shape. Note that the first plate member 560 may have an arbitrary shape such as a simple rectangular shape, a circular shape, or a polygonal shape. The cylindrical member 570 has the same overall length as the vertical dimension (height) of the beam BM. The second plate member 580 has a through-hole 580 </ b> A through which the shaft portion of the bolt member 220 of the tie-down hardware 200 can penetrate. Note that the second plate member 580 may have an arbitrary shape such as a circular shape or a polygonal shape.

  The first plate member 560 is disposed between the panel PN and the beam BM in a state where the shaft portion of the bolt member 220 is passed through the through hole 560A. At this time, since one side of the first plate member 560 is bent downward, this portion is locked to the shoulder portion of the panel PN, and the first plate member 560 rotates with respect to the panel PN. Is suppressed. Further, the cylindrical member 570 is inserted into the through hole TH1 of the beam BM, and the shaft portion of the bolt member 220 is passed through the inner diameter thereof. The second plate member 580 is placed on the upper surface of the beam BM in a state where the shaft portion of the bolt member 220 protruding upward from the cylindrical member 570 is passed through the through hole 580A. Here, in order to suppress the rotation of the second plate member 580 with respect to the beam BM, a rectangular recess CP into which the second plate member 580 is fitted can be formed on the upper surface of the beam BM. A fastener FM including, for example, a flat washer, a spring washer, and a double nut is screwed onto the male screw 220A of the bolt member 220 protruding from the second plate member 580. When the first plate member 560 has a simple rectangular shape, a rectangular recess (not shown) into which the first plate member 560 is fitted is formed on the lower surface of the beam BM, and the first The rotation of the plate member 560 can also be suppressed.

  In this way, the portion of the beam BM where the through-hole TH1 is formed is reinforced by the first plate member 560, the cylindrical member 570, and the second plate member 580, so that the fastening force of the tie-down hardware 200 is increased. Even if this works, it is possible to suppress the fastener FM located on the upper surface of the beam BM from being sunk into the beam BM.

  Even when the bolt member 220 protruding from the second plate member 580 is fastened via the box-shaped hardware 250 or the like, the box-shaped hardware 250 or the like is embedded in the beam BM by using the reinforcing hardware 550. Can be suppressed. Further, the reinforcing hardware 550 can be used not only for the structure shown in FIG. 12 but also for other structures. Furthermore, the reinforcing hardware 550 can be used not only for the beam BM but also for wooden building members such as a pillar PT.

  The second shear metal 400 that joins the upper surface of the panel PN and the lower surface of the beam BM can also be disposed as shown in FIG. That is, on the lower surface of the beam BM, instead of the circular hole CH1, a slit SL6 into which the joining member 430 of the second shear metal 400 can be fitted is formed. In addition, two circular holes CH2 into which the cylindrical member 420 of the second shear metal 400 is fitted are formed on the upper surface of the panel PN instead of the slit SL3.

  Then, in a state where the joining member 430 of the second shear metal 400 is fitted in the slit SL6 of the beam BM, a drift pin is driven from one surface of the beam BM, and the shaft portion of the through hole 430A of the joining member 430 is formed. By being penetrated, the beam BM and the second shear metal 400 are integrated. Further, the cylindrical member 420 of the second shear metal 400 is subjected to a shearing force acting on the panel PN by being fitted into the circular hole CH2 of the panel PN positioned below the cylindrical member 420. In addition, since the effect | action and effect of this structure are the same as that of the example demonstrated previously, the description shall be abbreviate | omitted (hereinafter the same).

  The tie-down hardware 200 is not limited to the configuration integrated with the panel PN, and may be integrated with the pillar PT as shown in FIG. That is, a stepped slit SL7 into which the tie-down hardware 200 can be fitted over the entire length is formed on one side surface of the pillar PT. The tie-down hardware 200 is fitted into the slit SL7 of the pillar PT, and the pillar PT and the tie-down hardware 200 are integrated by, for example, an adhesive or a drift pin.

  In this case, the lower surface of the pillar PT is divided into two parts: a protruding portion in which the tie-down hardware 200 is fitted and a flat portion in which the tie-down hardware 200 is not fitted. For this reason, in order to support the lower surface of the pillar PT, a box-shaped hardware 250 and a spacer hardware 300 are used in place of the vertical material joining hardware 100. That is, the flat portion of the pillar PT is supported by the spacer hardware 300, and the protruding portion is fastened to the concrete foundation BS via the box-shaped hardware 250. In addition, since the fastening procedure of the spacer hardware 300 with respect to the concrete foundation BS is the same as the fastening procedure of the box-shaped hardware 250, the description is abbreviate | omitted (the following is the same). Further, the flat portion of the pillar PT can be supported by a box-shaped metal piece 250 instead of the spacer metal piece 300.

  In this way, the tie-down hardware 200 can be embedded in the pillar PT. And since the outer peripheral surface of the pillar PT becomes flat, for example, the four side surfaces forming the cross section of the pillar PT are covered with, for example, a gypsum board excellent in fire resistance, and the periphery is further covered with a wooden covering material. Therefore, it can be a building member that looks good and has fire resistance. Since the upper surface of the pillar PT and the lower face of the beam BM are joined by a tie-down hardware 200 integrated with the pillar PT, the connecting hardware 150 becomes unnecessary, and the slits SL1 and SL5 are formed in the pillar PT and the beam BM. Man-hours can be reduced.

  Furthermore, as a joint metal for joining the lower surface of the panel PN to the concrete foundation BS, a third shear metal 450 can be used instead of the first shear metal 350 as shown in FIG. In this case, two circular holes CH3 into which the cylindrical member 460 of the third shear metal 450 can be fitted are formed on the lower surface of the panel PN instead of the slit SL4. And the lower surface of panel PN is joined to concrete foundation BS by the circular hole CH3 of panel PN fitting to the cylindrical member 460 of the 3rd shear metal 450. FIG. In this case, the third shear metal 450 can receive a horizontal force that is moving in the horizontal direction while receiving the load in the vertical direction of the panel PN.

  As a joint metal for joining the upper surface of the panel PN and the lower surface of the beam BM, a fourth shear metal 500 can be used instead of the second shear metal 400 as shown in FIG. In this case, two circular holes CH2 into which the cylindrical member 520 of the fourth shear metal piece 500 can be fitted are formed on the upper surface of the panel PN instead of the slit SL3. And the circular hole CH2 formed in the upper surface of panel PN fits into the cylindrical member 520 of the 4th shear metal object 500, and the upper surface of panel PN and the lower surface of beam BM are joined.

  In the center of the upper surface and the lower surface of the pillar PT, slits SL1 into which the connecting hardware 150 can be fitted are formed along the axial direction of the beam BM. In addition, a small hole (not shown) for driving a drift pin into the through hole 150A of the connection hardware 150 is formed on one side surface of the pillar PT. On the other hand, the slit SL5 and the slit SL6 that can be fitted with the joining member 430 of the coupling metal 150 and the second shear metal 400 at predetermined positions on the upper surface of the beam BM located below and the lower surface of the beam BM located above. Are formed respectively. Further, the tie-down hardware 200 is integrated with the left and right side surfaces of the panel PN as in the previous embodiment, and the cylindrical member 420 of the second shearing hardware 400 is formed on the upper and lower surfaces of the panel PN. Are formed with two circular holes CH2.

  At a predetermined position on the upper surface of the beam BM located below, an anchor bolt AB projecting upward from the upper surface, and a fastener FM including a flat washer, a spring washer and a double nut threadedly engaged with the tip end portion thereof. Two box-shaped hardware 250 are fastened. That is, the box-shaped metal piece 250 is placed on the upper surface of the beam BM with the through hole 250A passing through the shaft portion of the anchor bolt AB, and the fastener FM is screwed onto the shaft portion of the anchor bolt AB protruding from the bottom plate. It is concluded by joining.

  The upper surface of the beam BM positioned below and the lower surface of the column PT are joined by fitting the connecting hardware 150 into the slit SL5 of the beam BM and the slit SL1 of the column PT. At this time, in order to ensure the joining of the column PT to the beam BM, a drift pin is driven from one side surface of the beam BM and the column PT, and the shaft portion penetrates the through hole 150 </ b> A of the connection hardware 150.

  The lower surface of the panel PN integrated with the tie-down hardware 200 is joined to the upper surfaces of the box-shaped hardware 250 and the beam BM. In other words, the shaft portion of the bolt member 220 of the tie-down hardware 200 passes through the through hole 250A of the box-shaped hardware 250, and the fastener FM is screwed into the male screw 220A. The lower end portion of the down hardware 200 is joined. At this time, the lower corners of the panel PN are notched into a rectangular shape so that the lower corners of the panel PN and the box-shaped hardware 250 do not interfere with each other. Further, the second shear metal 400 is joined to the upper surface of the beam BM located below by fitting the joint member 430 of the second shear metal 400 into the slit SL6. At this time, in order to ensure the joining of the second shear metal 400 to the beam BM, the drift pin is driven from one surface of the beam BM, and the shaft portion is penetrated into the through hole 430A of the joining member 430. Further, the lower end of the panel PN is joined to the second shear metal 400 by fitting the cylindrical member 420 into a circular hole CH2 formed on the lower surface of the panel PN.

  The lower surfaces of the beams BM located above are joined to the upper surfaces of the left and right pillars PT and the panel PN via the connecting hardware 150 and the second shearing hardware 400. That is, the connecting hardware 150 is fitted over the slit SL1 formed on the upper surface of the pillar PT and the slit SL5 formed on the lower face of the beam BM, and the drift pins are hit from one surface of the pillar PT and the beam BM, respectively. The shaft portion is inserted into the through hole 150 </ b> A of the connection hardware 150. Further, the cylindrical member 420 of the second shear metal 400 integrated with the beam BM is fitted in the circular hole CH2 of the panel PN. Further, the shaft portion of the bolt member 220 of the tie-down hardware 200 integrated with the panel PN is penetrated into the through hole TH1 of the beam BM, and the bolt member 220 protruding from the upper surface of the beam BM is formed on the bottom surface of the box-shaped hardware 250. The through-hole 250A is penetrated. A fastener FM is screwed onto the male screw 220A of the bolt member 220 protruding from the bottom plate of the box-shaped hardware 250.

  Note that when the fastener FM is tightened, the box-shaped hardware 250 has a larger plane than the bottom plate of the box-shaped hardware 250 between the box-shaped hardware 250 and the beam BM in order to prevent the box-shaped hardware 250 from entering the beam BM. For example, a plate (washer) PT made of a rectangular metal plate may be interposed. Further, the fastening of the tie-down hardware 200 to the beam BM is not limited to the box-shaped hardware 250, but may be performed only by the plate PT or the spacer hardware 300 in which a through hole is formed only on the bottom plate. Furthermore, in order to reinforce the through-hole TH1 of the beam BM, a reinforcing hardware 550 can be used as in the previous embodiment.

When the rectangular frame is deformed, the rectangular panel PN is fitted into the frame, so that the pillar PT contacts the side surface of the panel PN, and the deformation can be suppressed. In this case, a shearing force extending in the axial direction of the beam BM acts between the upper surface of the panel PN and the beam BM. The shearing force is received by the cylindrical member 420 of the second shear metal 400, and the frame It can suppress that a deformation | transformation becomes large too much. In addition, when a vertical load is applied to the rectangular frame, the cylindrical member 420 of the second shear metal 400 and the circular hole CH2 of the panel PN can be relatively displaced, so that the beam BM acts on the panel PN. Is interrupted. For this reason, it is not necessary to support a load with the panel PN, and the structural design of the gate-shaped frame can be facilitated.

  Also in the second embodiment, as shown in FIG. 18, the vertical direction of the second shear metal 400 can be reversed.
