Description

  The present invention relates to a jig for adjusting the verticality of both columns when the upper column is connected and fixed to the lower column of a steel frame.

  When connecting and fixing the upper column to the lower column, as a method of adjusting the verticality of both columns, the conventional method using jack equipment for adjusting the vertical accuracy of columns is a special steel plate for machine mounting (for example, splice) Plate) is welded to the top and bottom of the column and the verticality is adjusted to adjust the verticality such as the inclination of the column or the vertical direction (Patent Document 1).

  Therefore, it is necessary for the conventional jig for adjusting the verticality to weld a special splice plate for attaching the jig to the column, and it is necessary to remove the splice plate after adjusting the verticality. For this reason, the construction period is prolonged, so that the labor cost is improved and the construction material cost is also increased.

  Moreover, the conventional jig | tool for vertical degree adjustment adjusts the vertical degree of a pillar by applying force to one direction using a jack. For this reason, as shown in FIG. 6, in the case of a round pillar, it is necessary to install the verticality adjusting jig 200 at four places every about 90 degrees or six places every about 60 degrees. Further, in the case of a square steel pipe column, it is necessary to install one or two verticality adjusting jigs 200 on each surface, for a total of four or eight verticality adjusting jigs 200. Further, in the case of the H column, it is necessary to install six verticality adjusting jigs 200, and in the case of the cross H column, it is necessary to install five verticality adjusting jigs 200.

  In order to solve these problems, Patent Document 2 discloses a steel column having a first receiver 110 detachably fixed to one column and a second receiver 150 detachably fixed to the other column. A verticality adjusting jig 100 is described (see FIGS. 7 and 8). The first receiver 110 has a lower receiver 114 and an upper receiver 112 at both ends. The second receiver 150 is installed between the lower receiver 114 and the upper receiver 112 of the first receiver 110, and has a movable receiver 152 at substantially the center. In the verticality adjusting jig 100, an upper space in which a jack can be freely installed between the upper receiver 112 and the movable receiver 152 of the first receiver 110 and a jack between the lower receiver 114 and the movable receiver 152 of the first receiver 110. An installable lower space is formed, and the vertical degree is adjusted by installing and operating the jack 300 in the upper space or the lower space.

  In the verticality adjusting jig described in Patent Document 2, when the jack 300 is installed and operated in the upper space as shown in FIG. 8, the jack 300 is connected to the upper receiver 112 and the second receiver 150 of the first receiver 110. The movable receiver 152 is pressed. Here, since the first receiver 110 is fixed to the lower column, a downward force is applied to the upper column to which the second receiver 150 is fixed, and the upper column moves downward.

  On the other hand, when the jack 300 is installed and operated in the lower space as shown in FIG. 7, the jack 300 presses the lower receiver 114 of the first receiver 110 and the movable receiver 152 of the second receiver 150. As a result, an upward force is applied to the upper column to which the second receiver 150 is fixed, and the upper column moves upward.

  As described above, the verticality adjusting jig described in Patent Document 2 can adjust the verticality from two directions, upward and downward. Therefore, with this verticality adjusting jig, the verticality can be adjusted by installing the column on two surfaces in the X-axis direction and the Y-axis direction. Therefore, the time for attaching and removing the jig can be shortened, the working efficiency can be improved, and the cost can be suppressed.

  Further, in the verticality adjusting jig described in Patent Document 2, by changing the vertical direction of the second receiver 150 as shown in the two diagrams shown in FIGS. 7 and 8, the lower part of the first receiver 110 is changed. The distance between the bolt 170 for fixing the receiver 114 and the bolt 170 for fixing the second receiver 150 can be changed to match the shape of the column to be attached.

  However, in the verticality adjusting jig described in Patent Document 2, when the first receiver 110 is used in the arrangement shown in FIG. 7, for example, the jack 300 is connected to the lower receiver 114 and the second receiver 150 of the first receiver 110. When the movable receiver 152 is pressed, there is a problem that the lower receiver 114 and the movable receiver 152 are likely to wobble. For example, the lower receiver 114 and the movable receiver 152 are ideally moved up and down with a horizontal force applied, but are easily moved with one side biased. Only one side of the lower receiver 114 of the first receiver 110 is fixed to the longitudinal member of the first receiver 110, and the unfixed side is easy to open. Further, the lower support 114 is only fixed to the pillar, and the unfixed side is easy to open. Therefore, the side facing the column is easily moved with a bias. For this reason, there is a problem that the jack 300 is easily detached from the lower support 114 and the movable support 152.

  The first receiver 11 includes a lower receiver 12 and an upper receiver 13. The lower receiver 12 and the upper receiver 13 are fixed by two opposing fixing plates 31 and 32 that are respectively attached to two side surfaces that are perpendicular to the surface in contact with the column and in the vertical direction. The lower support 12 is detachably fixed to one pillar by being fixed to a bolt hole 51 provided in the one pillar with a bolt. An example of a component diagram for assembling the lower receiver 12 and the upper receiver 13 is shown in FIG. The lower support 12 includes a plate 15 installed in the horizontal direction and a plate 16 installed in the vertical direction. The plate 15 and the plate 16 are connected at a right angle. The plate 15 of the lower receiver 12 constitutes a surface that receives force from the jack. The plate 16 of the lower receiver 12 is formed with a bolt hole 14 for fixing to one pillar with a bolt.

  Grooves 33 and 34 extending in the vertical direction are formed in the fixing plates 31 and 32, respectively. The grooves 33 and 34 are holes for sliding the second receiver 21 in the vertical direction. An example of a component diagram for assembling the fixing plates 31 and 32 is shown in FIG.

  The second receiver 21 is installed between the lower receiver 12 and the upper receiver 13 so as to be slidable in the vertical direction. The second receiver 21 includes protrusions 22 and 23 on two side surfaces that are perpendicular to the surface in contact with the pillar and in the vertical direction, and the protrusions 22 and 23 are grooves 33 formed in the fixing plates 31 and 32, respectively. Fit into 34. The second receiver 21 can slide in the vertical direction as the protrusions 22 and 23 move in the vertical direction along the grooves 33 and 34. The second receiver 21 is detachably fixed to the other column by being fixed to the bolt hole 52 provided in the other column with a bolt. An example of a component diagram for assembling the second receiver 21 is shown in FIG. The second receiver 21 includes a plate 25 installed in the horizontal direction and a plate 26 installed in the vertical direction. The plates 25 and 26 are connected at right angles. The plate 25 of the second receiver 21 constitutes a surface that receives a force from the jack. The plate 26 of the second receiver 21 is formed with a bolt hole 24 for fixing to the other column with a bolt.

  FIG. 5 shows an assembly drawing of the vertical adjustment jig 10. The upper part of FIG. 5 shows the vertical degree adjusting jig 10 as viewed from the side surface perpendicular to the surface fixed to the column. The lower part of FIG. 5 shows a view of the verticality adjusting jig 10 as viewed from the side fixed to the column. The lower receiver 12 and the second receiver 21 are fixed to the column by bolts through bolt holes 14 and 24, respectively.

  In the verticality adjusting jig 10, an upper space in which a jack can be freely installed is formed between the upper receiver 13 and the second receiver 21 of the first receiver 11. Further, a lower space in which jacks can be freely installed is formed between the lower receiver 12 and the second receiver 21 of the first receiver 11. Accordingly, the vertical degree of the upper column can be adjusted by installing and operating the jack 40 in the upper space or the lower space.

  Specifically, when the jack 40 is installed and operated in the upper space, the jack 40 presses the upper receiver 13 and the second receiver 21 of the first receiver 11. Here, since the first receiver 11 is fixed to the lower column, a downward force is applied to the upper column to which the second receiver 21 is fixed, and the upper column moves downward. On the other hand, when the jack 40 is installed and operated in the lower space, the jack 40 presses the lower receiver 12 and the second receiver 21 of the first receiver 11. Since the first receiver 11 is fixed to the lower column, an upward force is applied to the upper column to which the second receiver 21 is fixed, and the upper column moves upward. Further, the verticality adjusting jig 10 can be fixed to the column in the direction opposite to the installation direction shown in FIGS. That is, in FIGS. 1 and 2, the lower receiver 12 is on the lower side and the upper receiver 13 is on the upper side, but the lower receiver 12 can be mounted on the upper side and the upper receiver 13 on the lower side. In this case as well, the vertical degree of the column can be adjusted similarly.

  Thus, the verticality adjustment jig of this embodiment can adjust the verticality in two directions, upward and downward. With the verticality adjustment jig of this embodiment, it is not necessary to install it on all four sides of the column, and adjust the verticality of both columns by installing it on at least two surfaces in the X-axis direction and the Y-axis direction. be able to. Therefore, the time for attaching and removing the jig can be shortened, the working efficiency can be improved, and the cost can be suppressed.

  As shown in FIGS. 1 and 2, the verticality adjusting jig of the present embodiment is configured to fix the lower receiver 12 of the first receiver 11 to the column by changing the vertical direction of the second receiver 21. The distance (indicated by “d” in FIGS. 1 and 2) between the bolt and the bolt for fixing the second receiver 21 to the column can be changed. Thereby, it can match | combine with the position of the bolt hole formed in the pillar to attach, and it can adapt to a pillar of various shapes.

  The bolts that fix the first receiver 11 and the second receiver 21 to the columns are bolts that are formed on the other column and one column at least with the diameter of the shaft on the proximal end side, that is, the diameter of the shaft near the head of the bolt. It may be the same as the diameter of the hole. If the diameter of the shaft on the base end side of the bolt is the same as the diameter of the bolt hole of the other pillar and one pillar, the other pillar is moved in conjunction with the movement of the second receiver 21 of the verticality adjusting jig 10. Can move stably. The diameter of the bolt shaft may be the same thickness from the proximal end to the distal end, or the proximal end side may be formed thicker than the distal end portion. If the diameter of the shaft on the base end side of the bolt is formed to be thicker than the diameter of the tip, it is possible to prevent the adjustment of the verticality of the other column from being hindered by the movement of the tip of the bolt.

  In addition, in the case of the verticality adjustment jig of the present embodiment, the G level pin is placed in one place above and below the column joint surface, thereby maintaining the level of that portion, thereby opposing the inserted G level pin. It is possible to adjust the verticality only at the two positions of the 90 ° and 180 ° directions on the pillar surface, which can improve work efficiency.

  The present invention can be suitably used as a jig for adjusting the verticality of a steel column.
