Description

  The present invention relates to an erection piece that is used to individually assemble a plurality of column components that are joined together to construct a column, and an attachment structure for mounting the erection piece to the column component. Here, the column component is made of precast concrete (PCa) and has a polygonal cross-sectional shape such as a rectangle.

  In the construction of a pillar made by adding multiple pillar components, adjustment of the inclination of the pillar component (upper pillar component) added to the previously built pillar component (lower pillar component) Adjustment, height adjustment, etc. (position adjustment) are performed. The adjustment of this position is performed by displacing the upper pillar constituent material with respect to the lower pillar constituent material.

  Conventionally, an erection piece made of a steel material is used to adjust the position of a steel column component (see Patent Document 1 described later). The erection piece is formed of a flat plate, and a plurality of pairs are attached to the upper end portion (column head) of the lower column component material and the lower end portion (column base portion) of the upper column component material by welding at the side edges of the flat plate. It is done.

  The displacement of the upper pillar constituent material is the erection piece (upper erection) located at the column base of the upper pillar constituent material with the erection piece (lower erection piece) located at the column head of the lower pillar constituent material as a reaction force support. This is done by applying an external force to the piece. In order to load the external force, an adjusting device is usually attached to each pair of upper and lower erection pieces.

  It can be considered that the erection piece having such a use is applied not only to the steel column component, but also to a precast concrete column component. As an erection piece applied to a precast concrete column component, for example, a T-shaped erection piece composed of two flat plates, that is, one flat plate and another flat plate welded so as to be orthogonal to the surface of the one flat plate The thing which consists of can be considered. According to this T-shaped erection piece, the one flat plate is attached to the side surface of the column component made of precast concrete via the other flat plate so as to extend in the vertical direction. It functions as an external force introducing portion for causing displacement of the material and as an attaching portion of the adjusting device. Here, a bolt is used for fixing the other flat plate to the column component made of precast concrete, and an insert capable of receiving the bolt is embedded in the column component made of precast concrete in advance. It is possible.

  By the way, in the construction using the column component made of precast concrete, the joint position of the column component may be set to a lower position than before. In this case, the upper area of the beam used as the arrangement area of the erection piece on one side surface of the column constituting material is narrow, and therefore, the arrangement area needs to be a side area of the beam. However, when the pillar constituent material has a polygonal cross-sectional shape such as a rectangle, the distance from the beam to the other side surface adjacent to one side face of the pillar constituent material is relatively short. In some cases, it is difficult for the side region to be the region where the erection piece is disposed.

  Referring to FIG. 1, a pillar component (lower pillar component) that has been built (arranged) and completed (arranged) in order to construct a pillar, and a column that is added to the lower pillar component material. The constituent materials (upper pillar constituent materials) are indicated by reference numerals 10 and 12, respectively. The upper column component 12 is in the process of being built on the lower column component 10.

  Both pillar constituent members 10, 12 are each made of precast concrete and have a polygonal cross-sectional shape. The two columnar constituent members 10 and 12 shown in the figure each have a rectangular cross section, and have four side surfaces 20 that define the rectangular cross section. In addition, a plurality of beam structural members 21 made of steel, which are part of beams to be constructed later, are joined to the column heads of the lower column structural members 10. The illustrated beam component 21 is disposed at a relatively high position on the column head of the lower column component 10.

  The upper and lower pillar constituent members 10 and 12 are used for adjusting the inclination of the upper pillar constituent member 12 with respect to the lower pillar constituent member 10, adjusting the misplacement, adjusting the height, etc. (position adjustment). A plurality of pairs (four pairs in the illustrated example) of upper and lower erection pieces 14 and 16 made of a steel material according to an example of the present invention are attached.

  A rod 22 extending upward as viewed in FIG. 1 is attached to the upper erection piece 16. The rod 22 releases the mounting state of the adjusting device 18 attached to each pair of both erection pieces 14 and 16 in order to adjust the position of the upper column component 12 and the accompanying erection pieces 14 and 16 from the both. Installed as needed to prevent falling.

  The two erection pieces 14 and 16 of each pair have the same outer shape or form except for the rod 22. The pair of erection pieces 14 and 16 are arranged at the upper end (column head) of the lower column component 10 and the lower end (column base) of the upper column component 12 so that they are vertically symmetrical. Is done.

  As shown in FIGS. 2 and 3, each erection piece 14, 16 has a first plate member 24 and a second plate member 26 fixed to the first plate member.

  In the illustrated example, the first plate member 24 of the erection piece is a flat plate. The flat plate has both end edges 28 and 30 and side edges 32 connected to the both end edges. As shown in FIG. 1, both end edges 28 and 30 of the first plate member 24 are positioned above and below, and the side edges 32 extend linearly in the vertical direction.

  The second plate member 26 of the erection piece is formed of a chevron plate and has two plate portions 34 having the same shape. Both plate portions 34 define two surfaces 33 having the same intersection angle as the angle (90 degrees in the illustrated example) at which the two side surfaces 20 adjacent to each other of the pillar constituent members 10 and 12 intersect. Accordingly, the two surfaces 33 can abut against the two side surfaces 20 of the column constituting member. Thereby, each erection piece 14 and 16 can be arranged at a corner portion that is an intersection of the two side surfaces 20 of each column component 10 and 12 via the second plate member 26. The second plate member 26 disposed in the corner portion is fixed to the column component material by using an appropriate fixing means, preferably via a post-installation structure 56 described later.

  The second plate member 26 having a mountain shape is made of angle steel in the illustrated example. Instead of the illustrated example, the second plate member 26 may be, for example, a plate folded in two and two plates welded at their side edges so as to form an angle with each other.

  By the way, the T-shaped erection piece described at the beginning of the present specification is arranged in the upper region A of the beam component 21 or the side region B (FIG. 1) of the beam component 21 on one side surface 20 of the column component. Is done. However, as described above, the beam component 21 is at a relatively high position (therefore, the joint position of the column component is at a relatively low position), and the distance from the beam component 21 to the top surface of the lower column component 10 Is smaller than the vertical dimension of the T-shaped erection piece, the T-shaped erection piece cannot be disposed in the upper region A. For this reason, at this time, the T-shaped erection piece is arranged in the lateral region B. However, depending on the size of the width dimension of the beam component 21, the distance between the beam component 21 and the side surface 20 of the lower column component 10 and the boundary 40 of the other side surface 20 adjacent thereto is relatively small. For this reason, when the T-shaped erection piece is disposed in the lateral region B, there may be a case where a sufficient space is not ensured between the other flat plate of the T-shaped erection piece and the boundary 40 of the lower column component 10. . In this case, when an external force is applied to the T-shaped erection piece, the concrete of the lower column component 10 that holds the T-shaped erection piece may be cracked or peeled off. For this reason, in reality, it is difficult to dispose the T-shaped erection piece in the side region B.

  On the other hand, the erection pieces 14 and 16 according to an example of the present invention can be arranged at the corners of the column constituent members 10 and 12 different from the upper region A or the side region B as described above. It is. From this, it is possible to avoid situations that may occur in the T-shaped erection piece, that is, difficulty in arranging the erection piece on the pillar constituent material.

  The two plate portions 34 shown in the figure constituting the second plate member 26 of the erection piece have rectangular outer shapes, but instead have other shapes and different shapes. It can be. The second plate member 26 has an outer corner portion 36 having a length dimension equal to that of the side edge 32 of the first plate member 24, that is, an outer corner portion 36 that defines the boundary between the two plate portions 34. Instead of this example, the length dimension of the outer corner portion 36 can be set to be smaller or larger than the length dimension of the side edge 32 of the first plate member 24 as necessary.

  The chevron plate (second plate member 26) is welded to the flat plate with the outer corner portion 36 in contact with the side edge 32 of the flat plate (first plate member 24). Via the flat plate. Therefore, when the erection pieces 14 and 16 are respectively attached to the column component members 10 and 12, the first plate member 24 moves up and down along the boundaries or ridge lines 40 of the side surfaces 20 adjacent to each other of the column component members 10 and 12. Extend in the direction. The first plate member 24 functions as an external force introduction portion for adjusting the position with respect to the lower column component 10 of the upper column component 12 and an attachment unit of the adjustment device 18.

  In the example shown in FIGS. 2 and 3, the angle formed by one of the two plate portions 34 of the angle plate (second plate member 26) and the flat plate (first plate member 24), and the other The angle formed by the plate portion 34 and the flat plate (first plate member 24) is set to be equal. However, if necessary, the two angles formed by the flat plate (first plate member 24) and each plate portion 34 (second plate member 26) can be set different from each other (FIGS. 4 and 4). (See FIG. 5).

  The upper column component 12 is suspended by, for example, a crane (not shown) for building on the lower column component 10. An upper erection piece (not shown) similar to the upper erection piece 14 of the lower column component 10 is attached to the column head of the upper column component 12 prior to the installation of the upper column component (FIG. Not shown). Each erection piece 14, 16 has a hole 43 in the first plate member 24. The hole 43 is used as a wire insertion hole for passing a wire (not shown) used when the upper column member 12 is suspended. While the upper column component 12 is suspended, the adjusting device 18 is attached to the first plate member 24 of each pair of erection pieces 14 and 16. By attaching the adjusting device 18, the pair of erection pieces 14 and 16 are connected to each other at the first plate member 24, thereby ensuring the independence of the upper column component 12 with respect to the lower column component 10.

  As shown in FIG. 1, the adjusting device 18 has a ring member 44 that is vertically elongated. The ring member 44 is hung on the upper end edge 28 of the first plate member 24 of the upper erection piece 16 and receives a part of the first plate member 24 of both erection pieces 14 and 16. A pair of bolts 46 (only one of which is shown) and a single bolt 48 are screwed onto the ring member 44. The pair of bolts 46 are opposed to both surfaces of the first plate member 24 of the lower erection piece 14. The illustrated adjusting device 18 further includes an inclination adjusting mechanism 50.

  According to the adjusting device 18, the position of the upper column component 12 can be adjusted as follows. For example, one of the pair of bolts 46 is screwed and applied to one of both surfaces of the first plate member 24 of the lower erection piece 14, and the other bolt 46 is loosened so that the lower erection piece 14 is supported by the reaction force support. As a result, the ring member 44 can be moved horizontally. The ring member 44 that moves horizontally hits the first plate member 24 of the upper erection piece 16 and applies a horizontal force thereto. As a result, the upper pillar constituent material 12 that is integrated with the upper erection piece 16 is displaced with respect to the lower pillar constituent material 10, and the position of the upper pillar constituent material 12 is adjusted (adjustment adjustment).

  One bolt 48 is screwed and pressed against the lower end edge 30 of the first plate member 24 of the lower erection piece 14, thereby connecting the ring member 44 to each pair of upper and lower erection pieces 14 and 16. Can be fixed. As a result, the upper column component 12 is placed on the lower column component 10 in a self-supporting state.

  The tilt adjustment mechanism 50 is disposed between the upper end edge 28 of the first plate member 24 of the lower erection piece 14 and the lower end edge 30 of the first plate member 24 of the upper erection piece 16 through the ring member 44. Yes. The external force applied by the operation of the tilt adjustment mechanism 50 is applied to the upper erection piece 16 (hence the upper column component 12) using the lower erection piece 14 (hence, the lower column component 10) as a reaction force support, and thereby the upper column. The component 12 can be raised, or vice versa. Thereby, the inclination and height position of the upper pillar constituent material 12 with respect to the lower pillar constituent material 10 can be adjusted.

  In order to suppress the deformation of the second plate member 26 of each erection piece 14, 16 that receives the external force in accordance with the operation of the adjusting device 18, each erection piece includes the flat plate and the first plate constituting the first plate member 24. 2 having a plurality of reinforcing ribs 49 (FIGS. 2 and 4) fixed to the chevron plate constituting the two plate members 26, or having one reinforcing rib 49 (FIG. 5). desirable.
