Description

  The present invention relates to the joining of the pillar constituted by connecting the hole-down hardware fixed to the side surface of the pillar standing on the foundation and the anchor bolt embedded in the base and protruding on the foundation through the foundation. The present invention relates to a position adjusting hardware for hole down hardware used in the apparatus.

  In order to stand the pillar on the foundation placed on the foundation concrete, and to fix the pillar directly to the foundation and to stabilize the joining state, a hole down hardware is fixed to the side of the pillar, and the hole The down hardware and the tip (upper end) protruding through the base of the anchor bolt on the foundation side are tightly connected to each other, but this structure is the hole down hardware fixed to the anchor bolt position and the pillar. If the positions match, there is no inconvenience, but the positional relationship between the hole-down hardware and the anchor bolt is often not constructed as designed due to erroneous work.

  For this reason, a device that can be applied both when the positional relationship matches and when the positional relationship does not match has been devised.For example, a pair of cylindrical bodies are aligned and fastened to anchor bolts to form an adjustment hardware. The outer cylinder is fitted to the anchor bolt, and the upper end of the one cylinder is locked to the nut screwed to the anchor bolt, and the other cylinder of the adjustment hardware is fitted to the nut. A nut is screwed into the lower end of the bent bolt, the other cylindrical body is locked to the nut, and the upper end of the bent bolt is locked to a hole-down hardware fixed to the pillar. (For example, Patent Document 1).

  In the conventional example, the displacement between the hole-down hardware and the anchor bolt is absorbed by the bending form of the bending bolt to obtain a predetermined joining state of the column. However, the displacement is not always constant. Therefore, there is a case where the bent form cannot be absorbed, and there is inconvenience that a bent bolt having a suitable bent form has to be prepared separately.

  The present invention has been created with the object of providing a position adjusting hardware for hole down hardware that can widen the absorption range of misalignment in construction between the hole down hardware and the anchor bolt, paying attention to such a normal situation. .

An anchor bolt tip is embedded a base projecting base on through base on the foundation the foundation, be interposed between the hold-down hardware fixed to the pillars erected on the base, the said anchor bolt A hardware that joins a hole-down hardware, which is combined with the anchor bolt so as to rise or descend along the anchor bolt, and the upper end of the hardware is engaged with the first nut screwed to the anchor bolt. The first cylindrical body to be stopped is combined with a connection bolt that penetrates through the hole-down hardware and the upper end is engaged with the connection bolt that is locked to the hole-down hardware, and descends or rises along the connection bolt. And a second cylindrical body that engages with a second nut that is screwed to the connection bolt, and the first and second cylindrical bodies that are separated from each other are loosely inserted into the connection holes provided in each of the first and second cylindrical bodies. Adjustment phosphorus In the interconnected, it is obtained by the configuration.

  According to the present invention, even if there is an unexpected shift in the positional relationship between the hole-down hardware fixed to the pillar and the anchor bolt protruded from the base, this can be absorbed and fastened together. It is possible to provide a hardware having a wide misalignment absorption range suitable for firmly joining the column to the foundation concrete in a set with (and connecting bolts).

The front view which shows a use condition. The enlarged view of FIG. The top view of FIG.

In the figure, A is a position adjustment hardware for hole down hardware according to the present invention, and the position adjustment hardware A for hole down hardware includes a first cylindrical body 1 and a second cylindrical body 2 of appropriate lengths that are separate from each other. The connection holes 1b 'and 2b' formed by projecting semicircular ring-shaped connection pieces 1b and 2b on the peripheral sides of the main cylinders 1a and 2a of the cylindrical bodies 1 and 2 are formed of an oval ring body. The adjusting ring 3 is loosely inserted, and the first and second circular bodies 1 and 2 are connected between the connecting pieces 1b and 2b.

  This hole-down hardware position adjusting hardware A is erected on the base b (there is no inconvenience even when it is erected directly on the foundation concrete c via the column base hardware). The down hardware 21 and the anchor bolt 31 with the base embedded in the foundation concrete c are interposed between the tip 31a projecting from the foundation b through the foundation b, these are connected, and the column p is connected to the foundation concrete c. They are directly fastened and used to increase the joining strength of the pillars p.

  The hole-down hardware 21 is formed by projecting a rectangular frame-shaped locking frame 21b on the surface of the lower end of a flat plate-shaped mounting piece 21a that is long in the vertical direction, and the mounting piece 21a is overlapped on the surface of the column p. In addition, the fastening bolt 22 and the fastening nut 23 screwed to the fastening bolt 22 are fixed to the column p.

  A bolt 25 protruding from the through-hole 24 through the upper threaded portion 25a of the connecting bolt 25 is inserted into the through-hole 24 provided in the tightening receiving piece 21b 'which is the upper piece of the locking frame 21b of the hole-down hardware 21. A locking nut 26 is screwed onto the tip (upper screw portion 25a) of the screw, and the connection bolt 25 is assembled to the hole-down hardware 21, and the position adjustment for the hole-down hardware is made on the lower screw portion 25b side of the connection bolt 25. A lower threaded portion protruding from the main cylinder 2a by fitting the main cylinder 2a of the second cylindrical body 2 of the hardware A to the threaded portion 25b (by passing the lower threaded portion 25b through the main cylinder 2a). The second pressure receiving nut 4 is screwed to the tip of 25b, and the second cylindrical body 2 side of the hole down hardware position adjusting hardware A is assembled to the hole down hardware 21 side.

  On the first cylindrical body 1 side of the position adjustment hardware A for hole-down hardware, the main cylinder 1a is externally fitted to the tip 31a of the anchor bolt 31 protruding from the base b (the anchor bolt front 31a is attached to the main cylinder 1a). The first nut 5 is screwed and assembled to the tip 31a of the anchor bolt 31 protruding from the main cylinder 1a.

  When the first and second nuts 4 and 5 (including the locking nut 26 in the embodiment) are appropriately tightened, the first cylindrical body 1 descends along the anchor bolt 31 (first pressure receiving pressure). The second cylinder 2 is raised along the connecting bolt 25 (the lowering along the connecting bolt 25 is restricted by the second pressure receiving nut 4). And with respect to the adjustment ring 3, since the 1st, 2nd cylindrical bodies 1 and 2 are loosely fitted in the connection part piece 1b, 2b, and are combined in the relationship which can be freely rotated in the left-right direction and the up-down direction, The hole-down hardware 21 and the anchor bolt 31 are fastened through the hole-down hardware position adjusting hardware A and the connection bolt 25, and the column p is joined to the foundation c.

  The hole-down hardware 21 need not be limited to that of the structure of the embodiment. In short, any hole-down hardware 21 may be used as long as it is fixed to the pillar p and receives the load from the connection bolt 25.

  Further, the connection bolt 25 may be provided with a screw over its entire length, or it may be a so-called bolt with a head, and there is no inconvenience. The locking nut 26 of the embodiment can be omitted, but the adjustment range is narrower than that of the embodiment.

  In addition, the first and second cylinders 1 and 2 can be freely used as the same shape in the embodiment (the second cylinder 2 is on the connection bolt 25 side and the first cylinder 1 is on the anchor bolt side). However, there is no inconvenience even if it is an irregular shape (for example, by changing the length of the main cylinders 1a and 2a).
