Abstract

(57) [Problem] To perform piping using a pipe fitting so that bolts of parts do not fall off from the pipe fitting. SOLUTION: A pair of mounting frames 1a and 1b, which are formed in a semi-annular shape projecting outward and are connected at one end to be openable and closable, and which can clamp a pipe P, project from the other end of the mounting frame. A pair of fixing pieces 2a, 2 having a plurality of bolt holes 3
b, a bolt 4 inserted into the bolt hole, a nut 5 screwed to the bolt, an inner diameter capable of engaging with a screw thread of the bolt,
It comprises a plate-shaped retaining piece 6 having a locking hole 7 inserted into a bolt between opposed fixing pieces. When the bolt is inserted into the fixing piece or the mounting frame is opened / closed in the piping work, the bolt is locked in the locking hole, so that it does not fall off.

Description

[Detailed description of the invention]

[0001]

[Technical field to which the invention belongs]

 The present invention relates to a device for fixing a pipe to an immovable portion such as a wall or a floor, which corresponds to a pipe such as a sprinkler, a water pipe, and a gas pipe.

[0002]

[Prior art]

 When piping is to be carried out on an immovable part of a building, for example, a wall, a pipe fitting is used which clamps and fixes the pipe using bolts and nuts on a bracket called a T-shaped foot attached to the wall.

[0003]

[Problems to be solved by the invention]

 When plumbing with pipe fittings, bolts often fall out of the pipe fittings. Bolts and nuts are in accordance with the standards of the pipe fittings and cannot be substituted, so any bolts that have fallen out must be picked up one by one. Recovering the bolts was troublesome as well, causing delays in piping work.

[0004] The problem to be solved by the present invention is to prevent bolts from coming off from pipe fittings that often occur during piping work.

[0005]

[Means for Solving the Problems]

 The feature of this invention is that it is formed in a semi-annular shape convex outwardly from each other, one end is connected to open and close, and a pair of mounting frames capable of holding a pipe, and the other end of the mounting frame, respectively. A pair of fixing pieces protruding and having a plurality of bolt holes, a plurality of bolts inserted into the bolt holes, a nut screwed into the bolt inserted into the bolt holes, and a screw thread of the bolt. It consists of a plate-shaped stopper piece having a lockable inner diameter and having a locking hole inserted into a bolt between opposed fixing pieces.

[0006]

BEST MODE FOR CARRYING OUT THE INVENTION The illustrated pipe fitting is of a known engagement type. Reference numerals 1a and 1b denote a pair of mounting frames, each of which is formed in a semi-annular shape convex outward. Reference numerals 2a and 2b denote a pair of plate-shaped fixing pieces, which protrude from one ends of the mounting frames 1a and 1b, respectively. A T-shaped female hole extends through the other end of one of the mounting frames, for example, 1a, and a T-shaped male piece projects from the other end of the other mounting frame 1b. By engaging the male piece with the female hole, the two mounting frames 1a and 1b are connected to be openable and closable. In the hinge type pipe fitting, both mounting frames are connected by a hinge so as to be freely opened and closed.

[0007] Reference numeral 3 denotes two bolt holes, which penetrate the fixing pieces 2a and 2b so as to face each other. Reference numeral 4 denotes a bolt inserted into the bolt hole, and reference numeral 5 denotes a nut, which is screwed to the bolt 4. The inner diameter of the bolt hole 3 is larger than the outer diameter of the bolt 4 so that the bolt can be easily inserted during piping work.

[0008] Reference numeral 6 denotes a thin plate-shaped stopper piece, which has a locking hole 7 through which the bolt 4 is inserted. The locking hole 7 has an inner diameter through which the bolt 4 can be inserted, but which is easily locked to the thread of the bolt. During the piping work, the retaining hole 6 is expanded due to the contact of the locking hole 7 with the bolt 4 so that the retaining hole 6 does not serve as a bolt retaining function, or the retaining piece 6 is stored without using pipe fittings. Metal pieces, such as stainless steel pieces, are used so that they do not deteriorate over time.

A procedure for raising the pipe P along the wall 11 and fixing the pipe P to a commercially available T-shaped foot 12 via the pipe fitting of the present invention will be described with reference to FIG. One fixing piece, for example, the bolt 4 sequentially inserted through the bolt hole 3 of 2a and the locking hole 7 of the retaining piece 6 is inserted into the bolt hole 13 of the T-shaped foot 12 so that the pipe P is inserted inside the mounting frame 1a. Press. Next, the mounting frame 1b is closed, the bolt 4 is inserted into the bolt hole 3 of the fixing piece 2b, and then the pipe P sandwiched between the mounting frames 1a and 1b is fixed to the T-shaped foot 12 by tightening the nut 5. During this piping work, the bolt 4 is locked in the locking hole 7 so that the bolt does not come off.

[0010]

[Effect of the invention]

 Since the bolts do not fall out of the pipe fittings during piping, piping work can be performed efficiently.
