`
`
`[0001] BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a
`joining structure of a steel pipe column and a PC plate that can be applied to artificial ground and the like.
`
`[0002] 2. Description of the Related Art PC plates (precast concrete plates) are precast plate-shaped concrete
`building materials, and can adopt a dry method except for joint portions. Since the maximum thickness of the
`PC board is about 30 cm, when a thick PC board is used for the construction of artificial ground as a floor board,
`it has sufficient rigidity, so it is possible to construct an artificial ground without floor beams. It is.
`
`[0003] However, when the column is used as a steel pipe column, it is difficult to join the PC plate to the steel
`pipe column in terms of shape because the steel pipe column and the PC plate are made of steel and concrete.
`There is a problem that there is.
`
`[0004] Therefore, conventionally, when constructing an artificial ground, as shown in the perspective view of
`FIG. 5, a plurality of columns 21 such as steel pipe columns are erected in the shape of a ridge, and the space
`between the front, rear, left and right columns 21 is H. A method is generally used in which beams 22 such as
`shaped steel are connected, floor plates 23 such as deck plates are arranged on these beams 22, and concrete is
`placed thereon to form a floor 24.
`
`[0005] However, the above-described conventional method for constructing artificial ground has a problem that
`the number of man-hours is large, such as connecting columns and beams by welding or placing concrete. .
`
`[0006] The present invention has been made to solve the above-mentioned problems of the prior art, and it is
`possible to easily construct an artificial ground or the like using a steel pipe column and a PC plate. The object
`is to provide a joint structure.
`
`[0007] According to the present invention, there is provided a joining structure of a steel pipe column and a PC
`plate, a steel pipe column, a plate-like support member fixed to the top of the steel pipe column, and a PC plate
`supported by the support member. And an anchor bolt for fastening the PC plate and the support member from
`above and below.
`
`[0008] Further, the PC plate is provided with a slip-out prevention plate for preventing the anchor bolt from
`slipping out.
`
`[0009] Further, a fitting metal is arranged at a joint portion between the PC plates. In the joining structure of the
`steel pipe column and the PC plate according to the present invention, the PC plate can be connected to the steel
`pipe column with an anchor bolt via a support member. Since the PC board itself can support the load on the PC
`board by making the PC board rigidity sufficiently large, the beam is placed between the columns as in the case
`of constructing a conventional artificial ground. There is no need to connect or to place concrete to construct the
`floor surface, and an artificial ground or the like can be easily constructed.
`
`[0010] In addition, by providing an anti-slip plate on the PC board, it is possible to prevent the anchor bolt from
`starting when a horizontal force acts on the PC board due to an earthquake or the like, so that the earthquake
`resistance of the artificial ground and the like can be improved. it can.
`
`[0011] In addition, when a horizontal force is applied to the PC plate, in-plane shearing or tensile force is
`generated, but in response to this, an in-plane shearing force can be obtained by placing a fitting metal at the
`joint between the PC plates. Can be transmitted to the PC plate via the fitting hardware.
`
`[0012] DESCRIPTION OF THE PREFERRED EMBODIMENTS Embodiments of the present invention will
`be described with reference to the drawings, taking as an example the case where the present invention is
`applied to an artificial ground.

`
`

`

`[0013] FIG. 1 is an explanatory view showing an embodiment of a joining structure between a steel pipe column
`and a PC plate according to the present invention. FIG. 1 (a) is a plan view showing the joining structure
`between the steel pipe column and the PC plate. (A) AA arrow directional view, (c) is a BB arrow directional
`view of (a). This artificial ground is composed of a plurality of PC plates supported by a plurality of steel pipe
`columns 1 erected on the ridges and a plate-like support member 2 fixed to the top of the plurality of steel tube
`columns 1. 3 (individually indicated by 3a, 3b, 3c, 3d and 3e).
`
`[0014] The PC plate 3 has a length corresponding to several spans of the row of the steel pipe columns 1 but has
`a width corresponding to one span. And each of the both ends along the longitudinal direction of the PC plate 3
`is supported by a half area of the support member 2 fixed to the top of the steel pipe column 1 at a portion where
`the steel pipe column 1 is located, and two anchors are provided. -It is fastened to the support member 2 by bolts
`4.
`
`[0015] The connecting portion 5 (indicated by a dotted line) 5 in the longitudinal direction of the PC plate 3 may
`be located directly above the steel pipe column 1 as in the connecting portion of the PC plates 3a and 3b, or the
`PC plates 3c and 3d. You may make it locate in the middle of the adjacent steel pipe pillar 1 like a connection
`part.
`
`[0016] Note that the PC plate 3 located at the end of the artificial ground, such as the PC plates 3a and 3b,
`increases the width of the PC plate 3 or adjusts the position of the steel pipe column 1 so that the PC plate 3 The
`support member 2 is completely covered.
`
`[0017] The PC board 3 is provided with a through-hole for passing the anchor bolt 4, but the nut 5 is screwed
`into the anchor bolt 4 at the upper end portion of the through-hole, so that it is larger than the through-hole. A
`recess 6 having an area is provided.
`
`[0018] A slip-out prevention plate 7 having a through hole for passing the anchor bolt 4 is disposed on the
`bottom surface of the recess 6. This anti-slip plate 7 is welded to the reinforcing bar 8 of the PC plate 3 so as to
`be integrated with the PC plate 3 and embedded in the concrete 9. Therefore, the PC plate 3 is in a state of being
`fastened to the support member 2 by the anchor bolt 4 and the upper and lower nuts 5 through the anti-slip plate
`7. In order to fasten the anti-slip plate 7 side, as shown in FIG. 2, a key-shaped anchor 14 is used, and the end of
`the key-shaped anchor 14 is welded to the reinforcing bar 8. Also good.
`
`[0019] As described above, the PC plate 3 is fastened to the support member 2 through the anti-slip plate 7 for
`the following reason. As shown in FIG. 3A, when a horizontal force F acts on the PC plate 3 due to an
`earthquake, the anchor bolt 4 rotates in the direction of the arrow. As a result, as shown in FIG. 3 (b), the PC
`plate 3 has a bending moment in the direction of the arrow, causing a phenomenon that the anchor bolt 4 slides
`out of the PC plate 3. Function declines.
`
`[0020] In addition, a female screw may be provided in the through-hole 13 of the support member 2 and the
`anchor bolt 4 may be screwed into the female screw so that deformation around the support member 2 and the
`anchor bolt 4 can be suppressed to be small.
`
`[0021] When the anti-slip plate 7 is not installed, the anchor bolt 4 starts to slide due to a slight collapse of the
`concrete 9 around the anchor bolt 4, but when the anti-slip plate 7 is welded to the reinforcing bar 8, the anchor
`bolt 4 As long as the collapse does not occur over a considerable length of the reinforcing bar 8 welded with the
`anti-slip plate 7, the anchor bolt 4 does not start to slide, and the installation of the anti-slip plate 7 greatly
`improves the earthquake resistance.
`
`[0022] Of course, the anti-slip plate 7 is not necessary and need not be provided when it is not necessary to
`consider the horizontal force due to an earthquake or the like. As shown in FIG. 1 (b), the PC plates 3 where the
`PC plates 3 are in contact with each other on the steel pipe column 1 (for example, the contact portion between
`the PC plate 3 a and the PC plate 3 c) A recess 10 is provided in each, and a joint metal 11 welded to the
`reinforcing bar 8 is provided on the bottom surface of the recess 10, and the side surfaces of both the joint
`hardware 11 are abutted against each other on the PC plates 3 a and 3 b. Laid. Then, the backing plate 12 is
`placed on the joint hardware 11 across both the joint hardware 11 so that the butt portion is centered after laying,
`and the peripheral portion of the contact plate 12 is welded to the joint hardware 11. Of course, the joint
`hardware 11 and the contact plate 12 may be fastened with bolts and nuts.
`
`
`Page 7 of 8
`
`

`

`[0023] Thus, the reason why the joint hardware is provided at the contact portion between the PC plates 3 is to
`transmit the in-plane shear force between the PC plates 3, thereby integrating the plurality of PC plates 3.
`
`[0024] The joint hardware 11 is also disposed at the connecting portion in the longitudinal direction of the PC
`plate 3, and the contact plate 12 is welded in the same manner so as to integrate the adjacent PC plates 3. Thus,
`after integrating the whole PC board 3, the recessed part 6 and the recessed part 10 of the PC board 3 are filled
`with a concrete as needed.
`
`[0025] FIG. 4 is a view taken along the line CC in FIG. 1B, but the support member 2 that supports the PC plate
`3 is made of a substantially square steel plate, and the vertical and horizontal dimensions are the anchor bolts 4.
`Since the through-hole 13 o'clock for passing through is provided at the four corners, the outer diameter of the
`steel pipe column 1 is larger. The thickness of the support member 2 is about three times the diameter of the
`anchor bolt 4. The support member 2 is welded to the top of the steel pipe column 1 by welding.
`
`[0026] In the description of the embodiment of the joining structure of the steel pipe column and PC plate
`according to the present invention, the steel pipe column has been described as an example of a circular steel
`pipe, but the steel pipe column may be a square steel pipe. Moreover, the concrete filling steel pipe pillar which
`filled concrete inside may be sufficient.
`
`[0027] According to the present invention, an artificial ground can be constructed by using a steel pipe column
`and a PC plate, so that it is not necessary to perform conventional operations such as placing concrete and
`joining columns and beams to construct a floor surface. The process can be greatly shortened.
