[0004]

When the building wall surface 50 does not have sufficient strength, for example, when the studs are not fully inserted even in the ALC wall and the LGS wall, the pipe unit can be fixed only to the floor surface 51a. Fall and horizontal movement must be prevented. However, in the conventional example, as described above, since the piping unit is fixed by using the post-driving female screw type mechanical anchor bolt 63, the allowable pull-out load is not sufficient, and the anchor bolt 6 is used to prevent falling.
It was necessary to increase the diameter of 3 or increase the number. Further, in order to prevent horizontal movement, it is necessary to fix the stopper member to the floor surface 51a so as to be in contact with the piping unit, and therefore it is necessary to provide an additional anchor bolt.

Therefore, an object of the present invention is to provide a fixing structure for a piping unit which can fix the piping unit without increasing the diameter of the anchor bolt and increasing the number of anchor bolts.

[0006]

The pipe unit fixing structure of the present invention is expanded so that a pipe unit casing mounted on the floor and having a horizontal frame at its lower end, and a threaded portion projecting in the vicinity of the horizontal frame.

And a piping unit fixing bolt that presses and fixes the horizontal frame.

[0007]

According to the structure of the present invention, since the post-driving type male thread type mechanical anchor bolt is used, the allowable pulling load becomes larger than that of the female thread type. Therefore, it is not necessary to increase the diameter of the anchor bolts or increase the number of anchor bolts, and the anchor bolts can be easily installed. In addition, it is equipped with a positioning tool that inserts the threaded part of the anchor bolt into the insertion part and abuts the vertical piece on the side surface of the horizontal frame of the piping unit casing.The lower part of the connection nut is screwed onto the threaded part of the anchor bolt. By doing so, the positioning tool can be fixed to the floor surface. This can prevent horizontal movement of the piping unit casing in the direction orthogonal to the horizontal frame.

In addition to fixing the positioning tool by itself as described above, the horizontal frame can be fixed by using the fall prevention frame by screwing the piping unit fixing bolt on the upper portion of the connection nut. That is, the fall prevention frame is arranged on the upper surface of the horizontal frame, the piping unit fixing bolt is inserted into the insertion portion of the fall prevention frame, and the lower end thereof is screwed onto the upper portion of the connection nut. Accordingly, the fall prevention frame can be pressed downward to fix the horizontal frame, and the pipe unit casing can be prevented from falling.

The tipping-prevention frame 9 is a groove-shaped member having a length substantially the same as the depth of the piping unit casing 1 and opening downward, and a pipe unit fixing bolt 10 is provided on the upper piece.
Long holes (insertion parts) 14, 14 that can be inserted through
Are provided on both sides. The fall prevention frame 9 prevents the piping unit casing 1 from falling in the A direction in FIG. A nut 15 is screwed into the middle portion of the piping unit fixing bolt 10.

As shown in FIG. 4, the post-stretching male thread type mechanical anchor bolt 6 includes a main body composed of an expansion portion 16 embedded in the floor 20 and a screw portion 17 protruding from the floor surface 20a, and a main body. And a core rod 18 inserted into the main body. This post-drive type male thread type mechanical anchor bolt 6
Has a larger allowable withdrawal load than the post-strike female screw type mechanical anchor bolt.

Next, the construction procedure will be described. The marking is performed at the position of the floor surface 20a where the piping unit casing 1 and the post-driving male screw type mechanical anchor bolt 6 are arranged. As shown in FIG. 5 and FIG. 6, a hole 21 is provided in the floor 20 at the marking position, and the expansion portion 16 of the post-stretching male thread type mechanical anchor bolt 6 is inserted into the hole 21,
The core rod 18 is driven into the threaded portion 17 with a hammer 22. As a result, the expansion portion 16 is opened and bites into the inner wall of the hole 21 to be fixed. In this case, in the lower portion of the piping unit casing 1, in the vicinity of the opposing horizontal frames 3 and 3, the post-stretching male thread type mechanical anchor bolts 6 and 6 are provided.
Are provided respectively.

The piping unit casing 1 is temporarily placed on the floor surface 20a at the marking position, and the adjuster bolt 19 is used to level it and adjust its height. The horizontal portion 12 is placed on the floor surface 20 a by inserting the threaded portion 17 into the elongated hole 13 of the positioning tool 7, and the vertical piece 11 is brought into contact with the side surface of the horizontal frame 3. And
In this state, the lower part of the connection nut 8 is screwed into the screw portion 17 to fix the positioning tool 7.

Next, the fall prevention frame 9 is bridged over the upper surfaces of the opposing horizontal frames 3, 3 and the piping unit fixing bolt 10 is inserted into the elongated hole 14 and screwed onto the upper portion of the connection nut 8. Finally, the nut 15 is tightened and the fall prevention frame 9 is pressed downward to fix the lateral frame 3. According to this embodiment, since the post-driving type male thread type mechanical anchor bolt 6 is used, the allowable pulling load becomes larger than that of the female thread type. Therefore, it is not necessary to increase the diameter of the anchor bolts 6 or increase the number of anchor bolts 6, and the anchor bolts 6 can be easily installed. Moreover, the threaded portion 17 of the anchor bolt 6 is inserted into the elongated hole 13, and a positioning tool 7 that abuts the vertical piece 11 on the side surface of the horizontal frame 3 of the piping unit casing 1 is provided. The positioning tool 7 can be fixed to the floor surface 20 a by screwing the lower part of the connection nut 8 to 17.

Further, the connection nut 8 fixes the positioning tool 7 by itself, and as described above, the pipe unit fixing bolt 10 is screwed onto the upper portion of the connection nut 8 and the nut 15 is tightened to fix the tipping prevention frame. The lateral frame 3 can be fixed by pressing 9 downward. Thereby, the piping unit casing 1 can be prevented from falling. Further, since the fall prevention frame 9 is separated from the piping unit casing 1, the fall prevention frame 9 can be moved horizontally on the horizontal frame 3. For this reason, at the time of construction, even if the post-stretching male thread type mechanical anchor bolt 6 is installed at a position deviated from a predetermined position, it can be moved horizontally for construction. Further, the positioning parts 7 and the fall-prevention frame 9 are inserted into the elongated holes 13 and 14, whereby the position can be adjusted. This insertion part may be a notch.

FIG. 7 (seismic design and construction guideline for building equipment, 1984 edition, page 180, Japan Building Center, 1984) shows another post-driving male screw type mechanical anchor bolt 32, and an expansion portion 33. , A screw portion 34 and a nut 35. In this case, the lower end of the screw portion 34 is wide, and by tightening the nut 35, the lower end of the screw portion 34 rises to open the expansion portion 33. FIG.
Comparing the allowable withdrawal loads of 2 post-strike female thread type mechanical anchor bolts, the bolt diameter M6 ~
No. 12 has an allowable withdrawal load of 75 kgf, while the male thread type has a bolt diameter of M12 and has an allowable withdrawal load of 670 kgf.
Is.

The second embodiment will be described with reference to FIG.
In this embodiment, the positioning tool 25 includes a vertical piece 26 and a horizontal piece 27.
And the elongated hole 29 is similarly provided in the lateral piece 27. Further, the vertical piece 26 is extended in the direction of the horizontal frame 3, and its end portion is bent at a right angle to form a contact portion 28. The contact portion 28 contacts the end surface of the horizontal frame 3. This prevents horizontal movement of the piping unit casing 1 not only in the front-back direction but also in the left-right direction. Other structural effects are similar to those of the first embodiment.

A third embodiment will be described with reference to FIG.
In this embodiment, no nut is attached to the piping unit fixing bolt 30. In this case, the length of the piping unit fixing bolt 30 is determined according to the interval between the falling prevention frame 9 and the connection nut 8 so that the head of the piping unit fixing bolt 30 can press the falling prevention frame 9. In this embodiment, since the nut is unnecessary, the number of parts can be reduced. Other structural effects are similar to those of the first embodiment.
