Regarding the problems with the conventional methods described above, the base metal fittings that are generally used cannot be adjusted in height, so they have been prepared and used according to the height of the pipe. It is necessary to prepare several kinds of heights such as when there is a difference in level, which is very inconvenient, and since it is impossible to set a fine height, there is a problem that construction accuracy cannot be secured.
In addition, by fixing the L-shaped cross section and the support section having the inverted L-shaped cross section, the side plates are superposed, and bolts are inserted into the through holes that are the overlapping portions of the vertical long holes respectively provided on the side plates. A configuration comprising a conventional joining method in which a fastening nut is screwed from the side and the joining position of the fixing portion and the support portion is changed by adjusting the bolt and the fastening nut is also considered.
However, in this method, since the long hole is provided in the vertical direction, the support strength is insufficient because the vertical load applied to the support portion on which the pipe is placed is supported only by the tightening force of the bolt and the tightening nut. The problem that occurred.
Therefore, a long hole opened in the oblique direction is provided in one of the vertical long holes provided in the both side plates of the fixing part and the support part, and the other is changed to a long hole whose opening direction is opposite to the long hole. The method was also considered.
With this method, the side surface of the bolt abuts against the peripheral edge of the elongated hole with respect to the load in the vertical direction, so that downward sliding is suppressed, and the support strength is advantageous compared to the case where a vertical elongated hole is provided. However, the fixing part and the support part also move in the horizontal direction and the diagonal direction other than the vertical direction required as the adjustment direction, and the core position in the longitudinal direction of the pipe is shifted, and it is necessary to adjust the horizontal position. However, there were problems such as being troublesome.

  The present invention has been made in view of the above-described conventional problems. The purpose of the present invention is to easily adjust the piping to a predetermined interval with respect to the floor and the wall surface, and to accurately support the piping. Another object of the present invention is to provide a pipe support fitting that has sufficient strength and can be securely fixed.

As its means, claim 1 of the present invention is an L-shaped fixing body in which a fixing plate having one or more first elongated holes opened in an oblique direction is suspended upward from one end of the substrate; An inverted L-shape that is paired with the first elongated hole and has a second elongated hole that opens in a direction intersecting the opening direction, and is suspended downward from one end of the pipe support plate. A movable body is formed into a substantially U-shape by overlapping the fixed plate and the movable plate, and a bolt inserted into a through hole formed at an intersection of the first long hole and the second long hole, The structure fastened by the nut screwed to the bolt is provided with suppression means for suppressing horizontal movement of the movable body relative to the fixed body.

According to a second aspect of the present invention, as the restraining means, an L-shaped projecting piece in which the other end edges of the fixed plate or the movable plate are accommodated inside is bent and provided. It is characterized by that.

According to a third aspect of the present invention, as the restraining means, either one of a recessed groove portion or a protruding portion extending in the vertical direction is provided on the fixed plate, and the movable plate is fitted into the other recessed groove portion. It is the structure which provided the ditch | groove part which fits a protrusion part or a protrusion part, It is characterized by the above-mentioned.

According to a fourth aspect of the present invention, an abutting portion with which a bolt head abuts is formed in the vicinity of the first elongated hole of the fixed plate or the second elongated hole of the movable plate.

According to the first aspect of the present invention, an L-shaped fixing body in which a fixing plate having one or more first long holes with the support metal fitting body opened obliquely is suspended upward from one end of the substrate. And a reverse L-shape in which a movable plate which is paired with the first elongated hole and has a second elongated hole opened in a direction crossing the opening direction is suspended downward from one end of the pipe support plate. Bolts that are inserted into through holes formed at the intersections of the first and second elongated holes, with the movable body having a shape being substantially U-shaped by overlapping the fixed plate and the movable plate Since it can be moved up and down by tightening the bolt and nut, the height can be adjusted steplessly and the pipe can be supported with high accuracy.

When the height of the movable plate is adjusted by sliding the fixed plate and the movable plate, the movement of the movable plate in the horizontal direction is restricted. Since it can be moved only in the vertical direction, position adjustment in the longitudinal direction of the pipe becomes unnecessary.

A first long hole opened in an oblique direction provided in the fixed plate of the fixed body and the movable body and a second length opened in a direction intersecting the first long hole provided in the movable plate of the movable body. By tightening with a bolt inserted into a through hole formed at the intersection of the hole and a nut screwed to the bolt, the side surface of the bolt abuts against the peripheral edge of each elongated hole with respect to a vertical load. The sliding strength is suppressed, and the support strength is advantageous compared to the case where a vertical slot is provided.

According to a second aspect of the present invention, as the restraining means, either the fixed plate or the movable plate is provided with an L-shaped protruding piece bent at both ends so that the other end edges of the other end are accommodated inside. When the height is adjusted by sliding the fixed plate and the movable plate to be overlapped with each other, for example, if projecting pieces are provided at both ends of the movable plate, both end edges of the fixed plate are movable. Since it can be moved only in the vertical direction along the protruding pieces bent in an L shape provided at both ends of the plate, the position adjustment in the longitudinal direction of the pipe becomes unnecessary.
Further, the same effect can be obtained even in the case of a configuration in which protruding pieces are provided at both ends of the fixed plate.

According to claim 3 of the present invention, as the restraining means, either one of a recessed groove portion or a protruding portion extending in the vertical direction is provided on the fixed plate, and the movable plate is fitted into the other recessed groove portion. When the height is adjusted by sliding the fixed plate and the movable plate to be overlapped with each other by providing the projection portion to be fitted or the groove portion to be externally fitted to the projection portion, for example, providing the groove portion on the fixed plate, If a protrusion is provided on the movable plate, the protrusion can be fitted into the groove to restrict horizontal movement and move only in the vertical direction. Position adjustment is not necessary.
Further, the same effect can be obtained even in the case where the protrusion is provided on the fixed plate and the groove is provided on the movable plate.

According to claim 4 of the present invention, a contact portion with which the head portion of the bolt abuts is formed in the vicinity of the first long hole of the fixing plate, so that one piece of the head portion of the bolt contacts the contact portion. By restricting rotation in contact with each other, it is possible to prevent the bolts from rotating together when the nut is tightened, and work efficiency is improved.
