JP5677072B2 - Base plate and column base fixing structure using base plate - Google Patents

Description

  The present invention relates to a base plate for fixing a column base to an installation surface such as a floor, and a column base fixing structure using the base plate.

Conventionally, when fixing a column base to a foundation or a floor, a base plate whose outer peripheral edge protrudes outward from the side surface of the column base is welded to the lower end surface of the column base and integrated in advance. The vicinity of the outer peripheral edge is fixed to a foundation or a floor with an anchor bolt (see, for example, Patent Document 1).
Also, without integrating the column base and the base plate in advance, the base plate with the bolts integrated is fixed to the foundation or the floor with anchor bolts, and the column base and the base plate are connected with the bolts and nuts screwed into the bolts. There is also a way to do it.

In these base plates, through holes into which the anchor bolts are inserted are formed in advance, so that the position of the anchor bolt is determined when the position of the column base is determined.
However, if there is a risk that the anchor bolt may interfere with the reinforcing bars, piping, wiring, etc., embedded in the foundation or floor, the base plate may be shifted or the orientation changed in order to shift the anchor bolt. It is.
Here, if the position of the base plate is shifted, the position of the column base also shifts. However, if the base plate and the column base are not integrated, the direction of the base plate can be changed based on the position of the bolt (column base). The column base can be fixed to the foundation or floor without changing the position of the column base.

Hereinafter, a base plate and a column base fixing structure using the base plate according to an embodiment of the present invention will be described with reference to FIGS. 1 to 3.
As shown in FIGS. 1A and 1B, the base plate 1 according to the present embodiment is installed between the column base 12 and the floor F of the gantry 11 when the gantry 11 is fixed to the floor F of the building. ing.
As shown in FIGS. 2A and 2B, the base plate 1 includes a plate portion 2 fixed to the floor F, a bolt (fastening member) 3 protruding from the plate portion 2, and a screw engagement with the bolt 3. And a nut 4 to be provided.
Here, as shown in FIG. 1, the column base 12 of the gantry 11 is formed of a steel material having a substantially L-shaped cross section, and a plate 13 in which a through hole 13 a through which the bolt 3 can pass is formed in the lower end portion 12 a. It is attached. The gantry 11 is configured to be fixed to the base plate 1 by inserting the bolt 3 into the through hole 13 a of the plate 13 and fastening the nut 4 to the bolt 3.

As shown in FIG. 2A, in the plan view, the two adjacent corner portions 22 and 22 of the rectangle 21 leave a part of the side between the two corner portions 22 and 22 in plan view. Are formed into a hexagonal shape having a corner cutout 23.
2 (a) and 2 (b), the plate portion 2 has two holes 24 through which anchor bolts 14 (see FIG. 1) for fixing the plate portion 2 to the floor F are inserted. , 24 are formed.
The bolt 3 is located at a substantially central portion in the longitudinal direction of the plate portion 2 and is formed to protrude upward when the plate portion 2 is fixed to the floor F (see FIG. 1).

In order to fix the gantry 11 to the floor F as shown in FIG. 1 using the base plate 1 described above, first, anchor bolts 14 are installed on the floor F, and the anchor bolts 14 are provided in the holes 24 of the plate portion 2.
