Description

  The present invention relates to a column joining member used for a joint portion of a structure column using a steel pipe column and a column-beam junction structure using the same.

  Conventionally, in a structure using a steel pipe column, there is a portion where the column is joined in the vertical direction. In such a column junction, the size of the columns to be bonded vertically may be different. For example, the size of the upper column is smaller than the lower column. In such a case, there is a method using a taper-shaped bonding member between columns to be bonded.

  However, such a tapered member is difficult to manufacture. Further, since the tapered member and the upper and lower horizontal surfaces joined thereto are in contact with each other, the end surface of the backing metal, which is a plate-like member provided at the joint between the tapered member and the horizontal surface, and the horizontal surface are in surface contact. It is not line contact. For this reason, it is difficult to weld at this portion, which also causes poor welding. Therefore, simpler column joining structures with different sizes have been studied.

  As such a column joining structure, for example, a diaphragm is joined to the top and bottom of a frame-like column portion having at least one side tapered, and corresponds to the taper shape of the frame-like column so as to be flush with the side of the diaphragm. There is a connection column provided with a rib to perform (Patent Document 1).

  Further, there is a metal part for a joint part having a joint part with a column on the upper and lower surfaces and a through-hole or the like having a trapezoidal cross-sectional shape at the center of a part joined to the pillar (Patent Document 2).

Utility Model No. 3053480 No. 7-51524

  However, the connection column of Patent Document 1 is perpendicular to the joint with the beam, but has a tapered side surface and is difficult to manufacture, and as described above, the upper and lower sides of the tapered side surface are difficult to manufacture. It is also difficult to join the end surface and the upper and lower horizontal surfaces.

  Moreover, the metal part for a joint described in Patent Document 2 does not have a tapered side surface and is easy to manufacture, but it cannot be said to be an optimal shape in consideration of variations in the positional relationship between the upper and lower columns. .

  On the other hand, it is necessary to join the beam to an appropriate position according to the joining position of the pillars joined up and down. However, since the joining position of the beam is not clear with respect to the joining member between the columns, there is a risk of joining the beam at an incorrect position.

  The present invention has been made in view of such a problem, and can be used for column bonding at any position, is easy to manufacture, and does not mistake the beam bonding position. And it aims at providing the junction structure of a pillar and a beam using this.

  In order to achieve the above-described object, the first invention is a column joining member, which is a substantially rectangular flat plate-shaped main body that can be joined to a column on both sides, and at least three corners of the main body. And a mark portion indicating a beam joining limit position, wherein the base portion of the mark portion is a beam joining limit position.

  The mark part is visible from the upper and lower surfaces and side surfaces of the main body part, and the mark part is preferably a notch formed at four corners of the main body part. The cutout portion may be provided with a rib that is thinner than the main body portion.

  The mark portion is provided at each of the four corners of the main body portion, a column joint portion is provided on one surface of the main body portion, and the column joint portion is a portion other than the column joint portion on the surface of the main body portion. The column joint is eccentric with respect to the outer periphery of the main body, the eccentric distance of the column joint with respect to one side of the main body, and the one The outer edge of the region formed by connecting the bases of the mark part parallel to each side of the main body part in plan view of the main body part, the eccentric distance to the other side orthogonal to the side is substantially the same It is desirable that a part of the outer edge portion of the column joint portion substantially matches.

  The mark portions are respectively provided at four corners of the main body portion, and marks indicating the joining portions of the pillars to be joined at different positions are formed on one surface of the main body portion, and the marks are substantially rectangular. A first mark and a plurality of second marks provided on each side of the first mark so as to cross each side, and the center position of the first mark is the main body Is eccentric with respect to the outer periphery of the part, and the eccentric distance of the first mark to one side of the main body part and the eccentric distance to the other side orthogonal to the one side are substantially the same, A third mark indicating a mounting position of a column is formed at a corner of the column joint that is located on one eccentric side of the first mark and opposite to the other eccentric side, In plan view of the main body, the mask parallel to each side of the main body And the outer edge of the region formed by connecting the base ends of click portions, it is desirable that a part of the outer edge portion of the first mark is substantially aligned.

  A protrusion that indicates the center position of the main body may be formed around the column joint.

  According to the first invention, since the mark portions are formed at the four corners of the main body portion, when joining the beam to the side surface of the column joining member, the joining position of the beam is mistaken and outside the joined column. There is no need to join the beam. Moreover, if the mark part can be visually recognized from both the upper surface and the side surface of the column joining member, the beam joinable range can be surely known.

  As such a mark part, if it is a notch part, it is excellent also in manufacturability and excellent in visibility. Furthermore, it is possible to prevent stress from being concentrated on the notch by providing the rib on the notch.

  In addition, since the column junction is formed on one surface of the main body and the column junction is eccentric with respect to the main body, the column junction on the column junction side is changed to the column junction on the back side (main body Even if it is eccentric with respect to the center of the column, the column is always located on the column junction. Further, the column junction portion substantially coincides with a region formed by connecting the base portions of the mark portions. For this reason, there is no mistake in the direction and position which join a pillar. In particular, if the column bonding portion is convex or concave with respect to the surface, the column bonding position can be reliably confirmed. In addition, the column joint position can be easily grasped by configuring such a column joint portion with a plurality of marks.

  In addition, if a protrusion showing the center position of the main body is formed around the column junction, the column junction position on the non-eccentric side when used as a middle column or when used as a side column can be confirmed. In addition, it is possible to know the joining position of the column on the lower surface side.

  2nd invention is the joining structure of the pillar using the member for pillar joining, Comprising: The member for pillar joining is a substantially rectangular flat-plate-shaped main-body part which both surfaces can join with a pillar, and the four corners of the said main-body part. And a mark portion that indicates a beam joining limit position, and the mark portion is a notch portion formed at four corners of the main body portion, and is visible from the upper and lower surfaces and side surfaces of the main body portion. The base of the mark portion is a beam joining limit position, a hollow first column is joined to the lower surface of the column joining member, and a second column is joined to the upper surface of the column joining member, The beam-to-column connection structure is characterized in that the beam is bonded by aligning the end surface position of the beam with the beam bonding limit position of at least a part of the side surface of the column bonding member.

  The second column is smaller in size than the first column, the second column is eccentric to at least one side with respect to the first column, and the one side of the second column In the side column or the corner column in which the position of the outer surface of the first column is matched with the position of the corresponding outer surface of the first column, the second column connects the adjacent mark portions of the main body. It is desirable that the beam be joined by aligning the end face position of the beam with the beam joining limit position with respect to the eccentric direction of the second column on the side surface of the column joining member.

  According to the second invention, in the side column and the corner column, there is no mistake in the joining position of the upper column, and there is no mistake in the joining position of the beam when the columns are joined eccentrically.

  ADVANTAGE OF THE INVENTION According to this invention, it is possible to use it for the column joining of any position, it is easy to manufacture, and the member for column joining which does not mistake the joining position of a beam, and joining of a column and a beam using the same Structure can be provided.

  Hereinafter, a column-to-beam joint structure 1 according to an embodiment of the present invention will be described. FIG. 1 is a perspective view showing a part of a pillar-to-beam joint structure 1, and FIG. 2 is a cross-sectional view taken along line AA in FIG. In the illustrated example, an example of a joint structure between a column and a beam in a so-called side column is shown.

  In the column-to-beam bonding structure 1, columns 5a, 5b, and 5c are arranged in the vertical direction from below, and a bonding member 3 that is a column bonding member is provided between the columns. The upper end of the column 5a is bonded to the lower surface 13 of the lower bonding member 3, and the lower end of the column 5b is bonded to the upper surface 11. Further, the upper end of the column 5 b is joined to the lower surface 13 of the upper joining member 3. Further, the lower end of the column 5 c is joined to the upper surface 11 of the upper joining member 3.

  The columns 5a and 5b are hollow square steel pipes of the same size. The column 5c is a hollow square steel pipe having a smaller size than the columns 5a and 5b. The joining member 3 is a rectangular plate-like member having a size slightly larger than the size of the pillar 5b. The joining member 3 is made of, for example, steel and is approximately 300 to 1000 mm square, but can be arbitrarily set depending on the size of the columns to be joined.

  The beam 7 is joined to the column 5b in the range sandwiched between the joining members 3 in the horizontal direction. Therefore, the end portion of the flange portion of the beam 7 is joined to the side surface of the joining member 3, and the end portion of the web portion of the beam 7 is joined to the side surface of the column 5b. That is, the installation interval (the length of the column 5 b) between the upper and lower joining members 3 substantially matches the height of the beam 7. In addition, in order to avoid interference with the joining member 3, the notch is provided in the upper-lower-end part (flange part vicinity) of the web part of the beam 7. FIG.

  In addition, as shown in FIG. 2, the column 5 c may be arranged eccentrically with respect to the joining member 3. The joining position of the pillar 5c will be described later.

  Next, details of the bonding member 3 will be described. 3A is a plan view showing the joining member 3, and FIG. 3B is a front view. The main body of the joining member 3 is a substantially rectangular flat plate member. Notches 9 are provided at the four corners of the main body of the joining member 3. The shape of the notch 9 is, for example, a shape that is cut into a substantially rectangular shape (linearly) as illustrated. Although the shape of the notch 9 is not limited to the illustrated example, it is desirable that the boundary is clearly visible from both the upper and lower surfaces and the side surface of the joining member 3.

  A region surrounded by a straight line connecting the bases of adjacent corner cutout portions 9 is a column junction region 15. That is, the column bonding region 15 is formed in a substantially rectangular shape and becomes a bonding range of the above-described columns 5a, 5b, and 5c. In addition, the base of the notch 9 is a boundary portion of a portion other than the notch 9 and the notch 9 on each side surface of the main body of the joining member 3. Further, on the side surface of the joining member 3, the base portion of the notch portion 9 becomes the beam joining limit position 17. That is, the beam is not joined to the outside of the side surface of the joining member 3 beyond the beam joining limit position 17. Note that the region sandwiched between the beam joint limit positions 17 is a region where the beams can be joined, and thus is configured in a straight line in a plan view, and a step is formed outside the beam joint limit position 17 by the notch 9. The Therefore, the base part of the notch part 9 functions as a mark part for indicating a beam joining possible limit position.

  Next, the structure 25 using the joining member 3 will be described. FIG. 4 is a schematic plan view showing the structure 25, the periphery is covered with an outer wall 27, and columns 5b (5a) are installed at predetermined intervals. The columns 5b (5a) are connected by a beam 7. In FIG. 4, the illustration of the joining member 3 and the like is omitted for simplicity. On the column 5b (5a) installed below, a column 5c having a smaller size than the column 5b (5a) is installed.

  Here, a column at a portion where the beam 7 is joined in four directions is referred to as a middle column 19. Further, a column at a portion where the outer wall 27 is formed on one side is referred to as a side column 21. Further, a column formed at a corner of the structure 25 and where the outer wall 27 is formed in two directions is referred to as a corner column 23.

  In the middle column 19, the beam 7 is joined to both the vertical and horizontal sides in the horizontal direction, and the column 5c is arranged concentrically with respect to the column 5b (5a). That is, the center of the lower column 5b (5a) and the center position of the smaller column 5c coincide.

  On the other hand, in the side column 21, the center of the lower column 5b (5a) does not coincide with the center position of the smaller column 5c, and the column 5c is offset in one direction with respect to the column 5b (5a). They are arranged in a center (for example, upward in the figure). The column 5c is eccentric to the outer wall 27 side, and is disposed such that the side surface of the column 5b (5a) on the outer wall 27 side and the side surface of the column 5c on the outer wall 27 side are at the same position. That is, the pillar 5c is eccentric to one direction side (the outer wall 27 side) of the pillar 5b (5a), and is not eccentric to a direction perpendicular to the eccentric direction (for example, the left-right direction in the figure).

  On the other hand, the corner post 23 is eccentric in the respective directions of the outer wall 27 in contact with the two directions. The columns 5c are eccentric to the respective outer walls 27, and are arranged such that the side surfaces of the columns 5b (5a) on the outer wall 27 side and the corresponding side surfaces of the columns 5c on the outer wall 27 side are at the same position. That is, the column 5c is eccentric to one side (for example, the upper outer wall 27 side in the drawing) of the column 5b (5a) and is also eccentric by the same amount in a direction perpendicular thereto (for example, the right outer wall 27 side in the drawing). To do.

  Next, the arrangement of the pillars 5c with respect to the pillars 5b at the respective pillar positions and the joining positions of the beams will be described. FIG. 5 is a cross-sectional plan view showing a column-beam junction structure in the middle column 19.

  As shown in FIG. 5, in the middle column 19, the bonding member 3 is installed on the column 5 b, and the column 5 c is installed in the center on the bonding member 3. That is, the column 5 c is joined to the center of the joining member 3. Note that the center of the column 5b installed below the joining member 3 coincides with the center of the joining member 3 in any arrangement. In this case, the outer edge of the above-described column junction region 15 and the outer edge of the column 5b substantially coincide. Further, the column 5 c is bonded to the inside of the column bonding region 15.

  The flange portion of the beam 7 is joined to the side surface of the joining member 3. The beam 7 is joined at a position corresponding to the joining position of the column 5c. That is, at each side of each joining member 3, the beam 7 is joined to the joining member 3 so that the beam 7 does not protrude from the joining range of the column 5c corresponding to each side. Normally, the width of the beam 7 is narrower than the width of the column 5c.

  That is, in the middle column 19, the column 5 c is bonded to the center of the bonding member 3. Therefore, the beam 7 is joined to the approximate center of each side of the joining member 3. In this case, the beam 7 is joined to the inside of the region sandwiched between the beam joining limit positions 17.

  In addition, as shown in FIG. 6, in the middle pillar 19, the joining member 3 may be installed between the pillars 5a and 5b of the same size. In this case, the pillars 5 a and 5 b are installed at the center on the joining member 3. In this case, the outer edge of the above-described column junction region 15 and the outer edge of the column 5 substantially coincide. In the example shown in FIG. 6, the width of the beam 7 is narrower than the width of the columns 5a and 5b.

  As described above, the flange portion of the beam 7 is joined to the side surface of the joining member 3. In such a case, only the beam 7 may be eccentric. That is, the beam 7 may be joined at a position eccentric from the center of the columns 5a and 5b. Therefore, the beam 7 is joined eccentrically (upward in the drawing) from the center of the column 5b. At this time, the beam 7 is joined so that the end face of the beam 7 matches the beam joining limit position 17 indicated by the notch 9.

  At this time, a notch 9 is formed outside the beam joint limit position 17. For this reason, the beam 7 does not protrude from the joining range of the column 5b corresponding to the side. As described above, the column joining member 3 according to the present invention can join the beam 7 to an appropriate joining position because the joining limit position 17 is clear even when joining columns having the same size.

  FIG. 7A is a cross-sectional plan view showing a column-beam junction structure in the side column 21. As shown in FIG. 7A, in the side column 21, one side surface (upper side in the drawing) of the lower column 5 b and one side surface (upper side in the drawing) of the upper column 5 c with the joining member 3 interposed therebetween. And are installed so as to match. That is, the column 5 c is eccentric only to one side of the joining member 3. In the arrangement in the direction perpendicular to the side where the side faces coincide (the left-right direction in the figure), the center of the joining member 3 and the center of the column 5c coincide.

  As described above, the flange portion of the beam 7 is joined to the side surface of the joining member 3. The beam 7 is joined at a position corresponding to the joining position of the column 5c. That is, in the side column 21, the column 5 c is eccentric from the center of the joining member 3 to one side, and therefore the beam 7 is joined eccentrically from the approximate center of each side of the joining member 3. In the example shown in the figure, the column 5c is eccentric upward. In this case, the end portion in the eccentric direction becomes the outer wall. Since the beam 7 joined in the direction parallel to the eccentric direction (the beam 7 joined to the side opposite to the eccentric direction) is joined to the center of the side, it is the same as the middle column 19.

  On the other hand, on the side in the direction perpendicular to the eccentric direction (left and right direction in the figure), the beam 7 is eccentrically joined to the joining member 3 in the same manner as the column 5c. That is, the beam 7 is joined eccentrically in the eccentric direction (upward in the drawing) of the column 5c. At this time, the column 5 c is joined to the inside of the column junction region 15, and the outer edge of the column 5 c and the outer edge of the column junction region 15 substantially coincide with each other on the side in the eccentric direction. The beam 7 is joined so that the beam joining limit position 17 and the end face of the beam are aligned. At this time, a notch 9 is formed outside the beam joint limit position 17. For this reason, the beam 7 does not protrude from the joining range of the column 5c corresponding to the side.

  On the other hand, FIG.7 (b) shows the example using the joining member 3a which does not have the notch part 9. FIG. If there is no notch 9 that is a mark portion indicating the beam joining limit position 17, the beam 7 may be erroneously protruded from the beam joining limit position 17 and joined. That is, the beam 7 may protrude from the joining range of the column 5c corresponding to the side. In this case, the stress transmission between the beam 7 and the column 5c is not sufficient, and the designed strength cannot be ensured. By using the joining member 3, such a problem does not occur.

  FIG. 8A is a plan cross-sectional view showing a column-beam junction structure in the corner column 23. As shown in FIG. 8A, in the corner column 23, the one side surface (upper side in the drawing) of the lower column 5b and the one side surface (upper side in the drawing) of the upper column 5c with the joining member 3 interposed therebetween. Is installed so that one side surface (right side in the figure) of the lower column 5b in the direction perpendicular to the same side and the side surface (right side in the figure) of the upper column 5c coincide with each other. Is done. That is, the column 5c is eccentric in two directions perpendicular to each other of the joining member 3.

  As described above, the flange portion of the beam 7 is joined to the side surface of the joining member 3. The beam 7 is joined at a position corresponding to the joining position of the column 5c. That is, in the corner column 23, the column 5 c is eccentric in two directions from the center of the joining member 3, so that the beam 7 is joined eccentrically from the approximate center of each side of the joining member 3. In the example shown in the figure, the column 5c is eccentric upward and to the right. In this case, the end portion in the eccentric direction becomes the outer wall.

  The beam 7 is eccentrically joined to the joining member 3 in the same manner as the column 5c. That is, the beam 7 is joined eccentrically in the eccentric direction (upward and rightward in the figure) of the column 5c. At this time, the column 5 c is joined to the inside of the column junction region 15, and the outer edge of the column 5 c and the outer edge of the column junction region 15 substantially coincide with each other in the eccentric direction. The beam 7 is joined so that the beam joining limit position 17 and the end face of the beam are aligned. At this time, a notch 9 is formed outside the beam joint limit position 17. For this reason, the beam 7 does not protrude from the joining range of the column 5c corresponding to the side.

  On the other hand, FIG.8 (b) shows the example using the joining member 3a which does not have the notch part 9. FIG. If there is no notch 9 that is a mark portion indicating the beam joining limit position 17, the beam 7 may be erroneously protruded from the beam joining limit position 17 and joined. That is, the beam 7 may protrude from the joining range of the column 5c corresponding to the side. In this case, the stress transmission between the beam 7 and the column 5c is not sufficient, and the designed strength cannot be ensured. By using the joining member 3, such a problem does not occur.

  Usually, the pillars of different sizes installed above and below the joining member 3 are often different in size by about 50 mm to 150 mm. Therefore, the amount of eccentricity is approximately 25 mm to 75 mm.

  According to the joining member 3 according to the present embodiment, the joining member 3 having the same shape can be used for the pillar 5c at any position of the middle pillar 19, the side pillar 21, and the corner pillar 23. For this reason, it is not necessary to change a joining member with an installation position, and it can respond by the member of the same shape. Further, since the notch 9 is formed, the beam joining limit position 17 can be easily visually recognized on the upper and lower surfaces and side surfaces of the joining member 3. For this reason, the joining position of the beam 7 is not mistaken.

  In addition, although the column-joining member 3 of this embodiment provided the notch part 9 in each of four corners, this invention is not limited to this. FIG. 9A is a diagram illustrating a joint structure between a column and a beam in the side column 21. When the beam 7 is decentered in the eccentric direction of the column 5c and the beam 7 is bonded to the column joining member 3, the beam 7 is indicated by two notches 9 in the eccentric direction (upper left in the drawing) (upper left and upper right in the drawing). The end face position is matched with the beam joint limit position 17 to be measured. That is, in this case, the notch portions 9 at both ends of the side in the eccentric direction exhibit the function of positioning the beam 7.

  Similarly, FIG. 9B is a diagram showing a joint structure between a pillar and a beam in the corner pillar 23. When the beam 7 is decentered in the eccentric direction of the column 5c and the beam 7 is bonded to the column connecting member 3, the beam 7 is indicated by two notches 9 corresponding to the eccentric direction (upper left and lower right in the figure). The end face position is aligned with the joining limit position 17. That is, in this case, the notch 9 on the diagonal line corresponding to the eccentric direction exhibits the positioning function of the beam 7.

  That is, when used in this way, it is not necessary to form the notch 9 in the lower left corner of the column joining member 3 in the example shown in the figure. This is because it is not necessary to position the beam 7 in any of the middle pillars 19, the side pillars 21, and the corner pillars 23 in this portion. Therefore, in the present invention, the notches 9 may be formed in at least three of the four corners of the column joining member 3. In the following description, an example in which the notch 9 is formed at each of the four corners will be described.

  Next, another embodiment will be described. 10A and 10B are views showing the joining member 3b. FIG. 10A is a perspective view, FIG. 10B is a plan view, and FIG. 10C is a cross-sectional view taken along line BB in FIG. is there. Note that, in the following embodiment, the same reference numerals as those in FIG.

  The joining member 3 b has substantially the same configuration as the joining member 3, but differs in that a rib 29 is formed in the notch portion 9. The rib 29 is thinner than the main body of the joining member 3b. The thickness of the rib 29 is, for example, about half of the thickness of the main body. For this reason, the notch 9 is visible from the upper and lower surfaces and side surfaces of the joining member 3.

  The shape of the rib 29 is not limited to the illustrated example. Reinforcement is possible so that stress is not concentrated on the notch 9, and any form may be used as long as the notch 9 is visible.

  The effect similar to the joining member 3 can be acquired also by the joining member 3b. Further, by forming the rib 29, it is possible to prevent stress from concentrating on the notch portion 9.

  FIG. 11A shows still another embodiment. A column bonding portion 31 is formed on one surface of the bonding member 3c shown in FIG. The column junction portion 31 is formed to be slightly thicker on the upper surface than other portions. The column bonding portion 31 is a bonding portion with the column 5c bonded to the upper surface side of the bonding member 3c.

  The column joint portion 31 has a substantially same rectangular shape as the main body portion, and a column position mark portion 33 is formed at a predetermined corner of the column joint portion 31. Further, the column joining portion 31 is arranged eccentrically with respect to the main body portion of the joining member 3c. The column joint portion 31 is generally provided inside the column joint region 15, and two sides in the eccentric direction of the column joint portion 31 substantially coincide with the outer edge of the column joint region 15.

  In addition, although the column junction part 31 was formed so that it might each protrude with respect to another site | part, you may form so that the said part may be dented more thinly than another site | part.

  FIG. 12 is a view showing a joining position between the pillar joint portion 31 and the pillar 5c. FIG. 12A is a diagram showing the joining position of the pillar 5 c in the middle pillar 19. As illustrated in FIG. 12A, the column 5 c is bonded to the column bonding portion 31. At this time, the column 5 c is joined so as to be in contact with two sides of the column joint portion 31. For this reason, alignment of the pillar 5c is easy.

  FIG. 12B is a diagram showing the joining position of the column 5 c in the side column 21. As shown in FIG. 12B, the pillar 5 c is joined to the pillar joint 31 also in the side pillar 21. Even in this case, the column 5 c is joined so as to be in contact with the two sides of the column joint portion 31. For this reason, alignment of the pillar 5c is easy. In addition, the center column 19 and the side column 21 can match | combine the joining position of a column reliably by matching with the shape of the column position mark part 33. FIG.

  FIG. 12C is a diagram showing the joining position of the pillar 5 c in the corner pillar 23. As shown in FIG. 12C, the pillar 5 c is joined to the pillar joint 31 also in the corner pillar 23. Even in this case, the column 5 c is joined so as to be in contact with the two sides of the column joint portion 31. For this reason, alignment of the pillar 5c is easy.

  Furthermore, a projection 33 may be provided at the center of each side of the main body, as in the joining member 3d shown in FIG. The protrusion 33 is a mark portion indicating the center of the main body portion. By providing the protrusions 33 in this way, it becomes easy to align the center positions of the columns joined downward. In addition, the protrusion 33 can also be provided in the joining member concerning other embodiment mentioned above or other embodiment mentioned later.

  The same effects as those of the bonding member 3 can be obtained by the bonding members 3c and 3d. In addition, the joining position of the pillar 5c can be surely known. Moreover, if the protrusion 33 is provided, the center position of the joining member can be known. In addition, although the example which provided the rib 29 in the joining members 3c and 3d was shown, you may combine with the joining member 3. FIG.

  Next, another embodiment will be described. FIG. 13 is a view showing the joining member 3e. The upper surface 11 side of the joining member 3e is formed substantially flat. The upper surface 11 is provided with a substantially rectangular column position mark 16a which is a first mark. The column position mark 16a is, for example, a line drawn by a marking line, a minute groove, ink, or the like. The inside of the column position mark 16a is a column bonding position. That is, a part of the outer edge of the column position mark 16 a substantially coincides with the outer edge of the column bonding region 15 formed by connecting the bases of the notches 9. The various marks described below may be configured in the same manner as the column position mark 16a.

  The column position mark 16 a is arranged eccentrically with respect to the main body portion of the joining member 3. Column position marks 18a, 18b, and 18c, which are second marks, are provided so as to cross (cross) each side of the column position mark 16a. The column position marks 18a, 18b, and 18c prevent the column and the bonding member 3e from being displaced and joined by matching the center position of each side of the column when the column is bonded to the bonding member 3e. It is for grasping | ascertaining the joining position of a pillar.

  Each of the column position marks 18a, 18b, and 18c includes a pair of marks formed so as to intersect with the side of the column position mark 16a. The pair of marks are formed on two adjacent sides of the column position mark 16a, and are provided so that they are connected inside the column position mark 16a. That is, each of the column position marks 18a, 18b, and 18c is formed in an L shape so as to extend over two adjacent sides of the column position mark 16a.

  In addition, if a pair of marks are connected, it is not necessarily L-shaped, and may be connected obliquely with respect to the side of the main body inside the column position mark 16a or connected in an arc shape. . That is, it is only necessary that the pair of marks of the column position marks 18a, 18b, 18c can be distinguished from each other.

  Here, the column position marks 18a, 18b, and 18c may be any marking lines as described above. However, in order to more easily identify each of the column position marks 18a, 18b, and 18c, marking lines or the like may be used. The line types (for example, line thickness, broken line, solid line, one-point difference line, etc.) may be respectively changed, and the line colors may be separated. When changing these line types, it is not always necessary to change the line types of the column position marks 18a, 18b, 18c as a whole, and the intersections between the column position marks 18a, 18b, 18c and the column position mark 16a. It is only necessary to identify only the vicinity (only the vicinity of the position crossing the column position mark 16a).

  A pillar position mark 16b, which is a third mark, is formed at a predetermined corner of the pillar position mark 16a. The column position mark 16b is formed such that a part of the corner of the column position mark 16a is notched. A column position mark 16b is provided at a corner on one side in the eccentric direction (right side in the figure) with respect to each side of the column position mark 16a and on the opposite side (lower side in the figure) of the other eccentric direction.

  Note that different column position marks 16c and 16d are provided at corners of the column position mark 16a other than the column position mark 16b, and three corners other than the column position mark 16b can be identified. The column position marks 16c and 16d are, for example, lines provided at the corner of the column position mark 16a at an angle of about 45 ° with respect to each side, and can be distinguished from each other like a single line or a double line. The column position marks 16c and 16d are not identified by the number of lines as shown, but other symbols may be provided at the corners.

  Further, a part of the column position mark 18c at a position deviated from the center position of the corresponding main body portion in the other eccentric direction (upper side in the figure) on the side of the column position mark 16a in one eccentric direction (right side in the figure). Intersects the column position mark 16a (Z6 in the figure), and on the side of the column position mark 16a in the other eccentric direction (upper side in the figure), one eccentric direction (right side in the figure) from the center position of the corresponding main body. ), A part of the column position mark 18c intersects the column position mark 16a (Z5 in the figure).

  Similarly, on the side of the column position mark 16a in the other eccentric direction (upper side in the figure), a part of the column position mark 18b intersects the column position mark 16a at the center position of the corresponding main body (Z4 in the figure). Also, at the side of the column position mark 16a on the side opposite to the one eccentric direction (left side in the figure), the column position is offset from the center position of the corresponding main body in the other eccentric direction (upper side in the figure). A part of the mark 18b intersects the column position mark 16a (Z3 in the figure).

  Similarly, on the side of the column position mark 16a opposite to one of the eccentric directions (left side in the figure), a part of the column position mark 18a is a column position mark 16a at the center position (center line D) of the corresponding main body. At the center position (center line E) of the corresponding main body portion on the side of the column position mark 16a on the side opposite to the other eccentric direction (lower side in the drawing). A part of the position mark 18a intersects the column position mark 16a (Z2 in the figure).

  Each column position mark formed in this manner makes the column bonding position relative to the column bonding member 3e clear. That is, the same function as that of the column joint portion 31 described above is achieved. Specifically, when the column 5c is joined at the position of the middle column, the column 5c is positioned at the corner on the opposite side to the eccentric direction of the column position mark 16a (the lower left direction in FIG. 13 (a)). Combined. At this time, the two sides sandwiching the corner of the column 5c corresponding to the corner are arranged so as to overlap the two sides (lower side and left side in the drawing) of the column position mark 16a. In this state, the center positions of the two sides of the column 5c coincide with the column position mark 18a (Z1 and Z2 in FIG. 13). For this reason, the position with respect to the joining member 3 of the pillar 5c can be match | combined reliably.

  Similarly, when the column 5c is joined at the position of the side column, the column 5c is the other eccentric direction of the column position mark 16a and the corner on the opposite side to the one eccentric direction (upper left direction in the figure). The position is aligned with the portion (the column position mark 16c). At this time, the two sides sandwiching the corner portion of the column 5c corresponding to the corner portion are arranged so as to overlap the two sides (upper side and left side in the drawing) in the direction. In this state, the center positions of the two sides of the column 5c coincide with the column position mark 18b (Z3 and Z4 in FIG. 13). For this reason, the position with respect to the joining member 3 of the pillar 5c can be match | combined reliably.

  When the column 5c is joined at the corner column, the column 5c is aligned with the corner (column position mark 16d) in both eccentric directions (upper right direction in the figure) of the column position mark 16a. . At this time, the two sides sandwiching the corner of the column 5c corresponding to the corner are arranged so as to overlap with the two sides (upper right side in the figure) in the direction. In this state, the center positions of the two sides of the column 5c coincide with the column position mark 18c (Z5 and Z6 in FIG. 13). For this reason, the position with respect to the joining member 3 of the pillar 5c can be match | combined reliably.

  That is, a pair of column position marks 18a provided on each side opposite to the eccentric direction of the column position mark 16a with respect to the main body portion and formed at the center position of each side of the main body portion serve as a middle column mark. . Further, a mark formed on the other eccentric direction side of the column position mark 16a with respect to the main body portion and formed at the center position of the corresponding side of the main body portion; and one eccentric direction of the column position mark 16a with respect to the main body portion; A pair of column position marks 18b, which are provided on the opposite side and are formed at positions shifted from the center position of the corresponding side of the main body portion in the other eccentric direction, serve as side column marks. The column position mark 16a is provided on the other side in the eccentric direction with respect to the main body, and is formed at a position shifted in the one eccentric direction from the center position of the corresponding side of the main body, and the column position mark 16a. A pair of column position marks 18c, which are provided on one side in the eccentric direction with respect to the main body part and are formed at positions shifted from the center position of the corresponding side of the main body part in the other eccentric direction, are corner columns. Mark.

  Moreover, in order to confirm the installation direction of the joining member 3, the column position mark 16b is provided in the corner | angular part of the column position mark 16a. The column position mark 16b has a shape in which the outer shapes of the corners corresponding to the corresponding portions at the respective positions of the column 5c are overlapped when the column 5c is bonded at each of the intermediate column position and the corner column position. Therefore, when joining the joining member 3 on the pillar 5b, if the orientation of the pillar position mark is determined according to the position of the pillar 5c, the joining direction of the joining member 3 is not mistaken.

  The effect similar to the joining member 3 can be acquired also by the joining member 3e. In addition, the joining position of the pillar 5c can be surely known. In addition, although the example which provided the rib 29 in the joining member 3e was shown, you may combine with the joining member 3. FIG.

  Next, another embodiment will be described. 14A and 14B are views showing the joining member 3f, in which FIG. 14A is a perspective view and FIG. 14B is a plan view. The column joining member 3f has a notch 9 formed in an arc shape. Therefore, the side surface of the joining member 3 f other than the notch portion 9 is formed with a straight line, and the notch portion 9 is formed with a curve. That is, in the column joining member 3f, the boundary between the straight portion and the curved portion is the beam joining limit position.

  Further, as shown in FIG. 14B, a region formed by connecting the base portions (boundaries between the straight portion and the curved portion) of the adjacent notch portions 9 becomes the column joint region 15. It should be noted that the above-described column junction portion 31 and column position mark 16a may be formed in the column junction region 15.

  Thus, the same effect as that of the bonding member 3 can be obtained by the bonding member 3f.

  Next, another embodiment will be described. 15A and 15B are views showing the joining member 3g, in which FIG. 15A is a rear perspective view, and FIG. 15B is a bottom view. In addition, as the column bonding member 3g, the example of the column bonding member 3f (arc-shaped notch) is shown as the form of the notch portion 9, but the shape of the notch portion 9 and the aspect of the upper surface are as follows. The above-described embodiments can be applied.

  Ribs 12 are formed around the thin portion 14 on the lower surface 13 side of the bonding member 3g. The rib 12 has a substantially rectangular shape on the main body side (the base side of the rib) and becomes a circular shape toward the rib tip side (the top side). Accordingly, the thin portion 14 is substantially circular. A column joint 15 a is formed around the rib 12 on the lower surface 13. The column joint portion 15a is formed to be slightly thicker on the lower surface 13 than other portions. The column bonding portion 15a is a range bonded to the column on the lower surface side.

  The center lines of the column joint portion 15 a and the base portion (substantially rectangular portion) of the rib 12 coincide with the center line of the main body portion (outer shape) of the joining member 3. Here, in FIG. 15 a, lines D and E indicate center lines parallel to each side of the main body portion of the joining member 3.

  16 is a view showing the shape of the rib 12 at each corner of the rib 12, FIG. 16 (a) is a bottom view, FIG. 16 (b) is a cross-sectional view taken along the line BB of FIG. c) is a sectional view taken along the line CC of FIG. The rib 12 is formed so as to surround the thin portion 14.

  As shown in FIG. 16B, a part of the rib 12 becomes a notch 12a having a notched shape. Further, as shown in FIGS. 16B and 16C, the bottom of the thin portion 14 is formed in a tapered shape. In addition, when forming the column junction part 31 (FIG. 11) and the column position mark 16a (FIG. 13) in the surface side of the column junction member 3g, the angle of the rib 12 with respect to the eccentric direction of the column junction part 31 and the mark 16a. A notch 12a is formed in the part. The rib 12 has an effect of reinforcing the column joining member.

  Thus, the same effect as the joining member 3 can be acquired also by the joining member 3g. Since the rib 12 is formed around the thin-walled portion 14, the bottom (base) of the rib 12 is substantially rectangular, and the top is substantially circular, it is possible to appropriately reinforce the portion where stress is applied. It is possible to ensure the strength of a portion where stress around the thin portion 14 is likely to concentrate. Moreover, weight reduction can be achieved by forming the thin part 14.

  As mentioned above, although embodiment of this invention was described referring an accompanying drawing, the technical scope of this invention is not influenced by embodiment mentioned above. It is obvious for those skilled in the art that various modifications or modifications can be conceived within the scope of the technical idea described in the claims, and these are naturally within the technical scope of the present invention. It is understood that it belongs.

  For example, the shape of the column is not limited to the substantially square prismatic column as in the embodiment, and the present invention can be applied regardless of the column shape such as a substantially rectangular shape or a circular cross section. Moreover, although the example which forms the notch part 9 so that a beam joining limit position can be visually recognized from each direction of a joining member was shown, this invention is not limited to this. That is, as long as it can be easily visually recognized from each direction, any method may be used as long as the beam joint limit position can be confirmed by a marking line, painting, or other various methods.
