点があった。Problems to be Solved by the Invention In the above-mentioned conventional concrete foundation, anchor bolts are installed by attaching them to formwork etc. before pouring concrete, but if the positioning accuracy is not accurate, the removal of columns etc. 1 becomes impossible. However, it is extremely difficult to install these anchor bolts accurately, and they tend to go awry during concrete pouring, requiring correction work called resetting after the concrete has hardened, and the anchor bolts become attached to the tree. There was a drawback that the more work was done, the longer the work period and the higher the cost.

基礎集はH型鋼からなるためかなりの重量を有しており
、コンクリド打設時に狂う恐れが少ない。According to the above invention, the anchor bolt is attached to the steel foundation set installed along the longitudinal direction of the foundation.
If this Kiyama kat is installed accurately, the anchor bolt will naturally be placed accurately as well. Moreover,
Since the foundation collection is made of H-shaped steel, it is quite heavy, so there is little risk of it going awry during concrete pouring.

る。Embodiment FIG. 2 shows a foundation beam (1) of the present invention, which is installed so that its flanges (2) and (3) are vertically parallel to each other. ), a plurality of stiffener plates (5) are welded at intervals in the longitudinal direction so as to straddle the upper and lower flanges (2) and (3). (1)
A double bolt hole (6) is formed in the stiffener plate (5) to connect the stiffener plate (5) in the longitudinal direction, and a double bolt hole (7) is formed in the stiffener plate (5) to connect the stiffener plate (5) in a T-shape or a cross shape. These connections are made via junction plates. Further, the upper flange (2) is provided with a hole (8) for attaching an anchor bolt (9). For this installation, insert the lower end of the anchor bolt (9) into the hole (8), and insert it from both the upper and lower sides of the flange (2) with a pair of nuts (10) (10), which are also screwed into the male screws at the lower end. The tightening is designed to be fixed.
