BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a header fixing device for installing and fixing a header for branching pipe bodies such as water supply pipes and hot water supply pipes in a water supply and hot water supply system to a structure such as a wall surface or a floor surface of a building.

The header is generally installed on a structure such as a wall surface or a floor surface by being held horizontally across two holders. Here, as the holder, for example, a stopper in the tubular body holding device described in Patent Document 1 is used. In the holding device of Patent Literature 1, the fastener, which is a holder, is fixed to the wall surface at a predetermined distance from the wall surface of the structure through the mounting frame installed between the fastener and the wall surface.

By the way, in some cases, the holders are fixed to the structure by installing a pedestal on each of them, or by attaching both of them to a single flat plate-shaped fixing body having a large mounting area. In this case, as shown in FIG. 12, each retainer inserts and locks the retaining portion 72 into the locking hole 81 of the fixed body 80, and inserts the screw 75 into the insertion hole 74 of the fixing portion 73 on the opposite side. It is attached to the fixed body 80 by screwing into the screw hole 82 of the fixed body 80 .

Here, the retaining portion 72 of the retainer 70 is formed at the tip portion extending linearly from one end of the semicircular main body portion 71 , and the fixing portion 73 of the retainer 70 is formed at the main body portion 71 . Since the header 40 is formed at the tip of the portion that extends straight from the other end and then bends in the horizontal direction in the middle, the header 40 is formed vertically by the semi-arc main body 71 and the fixed body 80 . It is pressed and attached in contact with the surface of the fixed body 80 . Accordingly, when the header 40 is installed, it is not necessary to attach a mount to each holder 70, so the number of parts can be reduced and the installation work can be performed efficiently. As shown in FIG. 8, the header 40 is installed horizontally. In general, the axis of the branch pipe portion 42 branched from the main pipe portion 41 and connected to the pipe body is directed vertically downward. is installed on the fixed body 80.

JP-A-09-112751

However, the pipe bodies 50 such as water supply pipes and hot water supply pipes connected to the connection ports 42a of the branch pipe portions 42 branching from the main pipe portion 41 of the header 40 are pulled from the header 40 in a state distant from the header 40. In this case, the tubular body 50 is swung away from the surface of the fixed body 80 around the connection port 42a, as shown in FIGS. Then, the connection port 42a becomes a starting point.

On the other hand, as shown in FIG. 7 and the like, the header 40 is provided at its end with a hexagonal nut-shaped gripping portion 43 that protrudes outward from the main pipe portion 41 and grips a tool such as a wrench during attachment or detachment. . Here, the fixed body 80 to which the header 40 is fixed is formed in the shape of a single flat plate having a large mounting area, as described above. Therefore, when the header 40 is installed on the fixed body 80 , the grip portion 43 protruding outward from the main pipe portion 41 and the end portion of the main pipe portion 41 opposite to the grip portion 43 are separated from the fixed body 80 . It is attached to the fixed body 80 in contact with the surface. As a result, the rotation of the grip portion 43 about the tube axis is restricted by the fixed body 80, so that the orientation about the tube axis cannot be freely changed and is maintained at a constant rotation angle. Along with this, the main pipe portion 41 of the header 40 is also prevented from rotating about the pipe axis, and the branch pipe portion 42 branching from the main pipe portion 41 is also held in a fixed posture with the tip of the axis facing vertically downward.

In this way, the grip portion 43 of the header 40 is kept in contact with the surface of the fixed body 80 and is maintained at a constant rotation angle, and the branch pipe portion 42 of the header 40 is also in a constant posture with the tip of the axis directed vertically downward. Therefore, as described above, when the tubular body 50 connected to the header 40 is pulled and swung in the direction away from the fixed body 80, the axial direction of the branch tube portion 42 of the header 40 and the axial direction of the branch tube portion 42 are held. It is different from the axial direction of the tubular body 50 . Then, an unreasonable force such as bending is applied to the connecting portion between the tubular body 50 and the branch pipe portion 42, and there is a possibility that the tubular body 50 or the connector between the tubular body 50 and the connection port 42a may be cracked, damaged, deformed, or the like. There is

Hereinafter, a header fixing device according to an embodiment of the present invention will be described with reference to the drawings.
The header fixing device of the present embodiment is for installing and fixing a header for branching pipe bodies such as water supply pipes and hot water supply pipes in a hot water supply system or the like to a structure such as a wall surface or a floor surface of a building. In addition, in this embodiment, the header is installed on the floor surface.

As shown in FIG. 6, the header includes a circular tubular main pipe portion 41, a plurality of branch pipe portions 42 vertically branched downward from the main pipe portion 41, four branch pipe portions 42 in FIG. A hexagonal nut-shaped gripping portion 43 protrudes toward the side and holds a tool such as a wrench during attachment and detachment. A pipe body 50 such as a water supply pipe or a hot water supply pipe is connected downward to the connection port 42a of the branch pipe portion 42 .

1 to 3, the header fixing device 1 includes a strip-shaped holder 10 having a holder 11 for holding a header 40 and two mounting portions 12 provided on both sides of the holder 11, and a structure. and a fixed body 20 having a fixing portion 21 for fixing to the body and a panel-shaped main body portion 22 . Furthermore, the holding portion 11 of the holding fixture 10 has an enclosing portion 13 extending along the outer peripheral direction of the main pipe portion 41 of the header 40 and an opening portion 14 capable of receiving the main pipe portion 41 therein. Further, the body portion 22 of the fixed body 20 has a plurality of attached portions 23 to which the holders 10 are attached.

More specifically, the holder 10 is made of a metal material, a synthetic resin material, or the like. As shown in FIG. is narrower than the diameter of the main pipe portion 41 of the header 40 and holds the header 40 at a position separated from the surface of the body portion 22 of the fixed body 20 . In the state where the holder 10 holds the header 40 in the holding portion 11 and is attached to the main body portion 22 of the fixed body 20 , the header 40 is held by the surrounding portion 13 of the holding portion 11 and the main body portion 22 of the fixed body 20 . is formed so as to surround the entire outer periphery of the main pipe portion 41 of.

In addition, both of the two mounting portions 12 of the holder 10 have, on the distal end side thereof, a distal end locking portion 15 that is inserted into the mounted portion 23 of the fixed body 20 and that is locked to the rear surface of the main body portion 22. ing. More specifically, the two mounting portions 12 are a linear locking portion 16 that extends linearly from one end of the enclosing portion 13 and has a distal end locking portion 15 formed on the distal end side, and an engaging portion other than the enclosing portion 13 . and a bent engaging portion 17 that is bent away from the enclosing portion 13 from the end side and has a distal end engaging portion 15 formed on the distal end side. The linear engaging portion 16 and the curved engaging portion 17 mean the entire portion from one end and the other end of the enclosing portion 13 to the tip, respectively.

The tip locking portion 15 formed on each tip side of the linear locking portion 16 and the curved locking portion 17 includes a shaft portion 15a extending from the tip side and a shaft portion 15a further to the tip side of the shaft portion 15a. and protruding on both sides in the width direction of the holder 10, and are respectively hooked to the peripheral edges of the upper through-hole 24 and the lower through-hole 25 on the back surface of the main body 22 of the fixed body 20 15b and .

The curved locking portion 17 of the holder 10 has a surface contact portion 18 that contacts the surface of the body portion 22 between the other end of the enclosing portion 13 and the distal end locking portion 15 . In addition, the holder 10 is flexurally deformable in the direction in which the linear engaging portion 16 is separated from the curved engaging portion 17, and the flexural deformation expands the opening 14 so that the header 40 can be received therein. It has become. Further, in the state where the distal end engaging portion 15 of the linear engaging portion 16 and the distal end engaging portion 15 of the curved engaging portion 17 are located on the back surface side of the main body portion 22, the holder 10 has the header 40 inside. Press and hold.

On the other hand, as shown in FIGS. 1 and 2, the fixed body 20 is formed of a single metal plate or synthetic resin plate, and includes a fixing portion 21 for fixing to a stand (not shown) erected on the floor surface. It consists of a rectangular panel-shaped main body 22 . The fixed part 21 is formed of a plurality of screw mounting holes provided at both left and right ends of the fixed body 20 at intervals in the vertical direction. It is fixed on the floor by screwing it to a pair of left and right stands. The plurality of attached portions 23 of the main body portion 22 are formed of through holes penetrating through the main body portion 22 from front to back. A pair of through holes are provided above and below one holder 10, the upper through hole 24 is formed in a substantially convex shape, and the lower through hole 25 is formed in a rectangular shape. The upper through-hole 24 has a rectangular wide through-hole 24a through which the front end engaging portion 15 of the linear engaging portion 16 of the holder 10 can pass from the surface side of the main body portion 22, and a wide through-hole 24a below the wide through-hole 24a. and a rectangular narrow through portion 24b narrower than the wide through portion 24a. The through hole 25 on the lower side extends toward the through hole 24 on the upper side. 22 is formed in a size that allows it to pass through the front end engaging portion 15 from the surface side thereof.

After the linear locking portion 16 of the holder 10 is inserted into the wide through-hole 24a of the upper through-hole 24 of the fixed body 20 and pushed down by the narrow through-hole 24b, it is inserted into the wide through-hole 24a, which is an empty space. , a separate proximity maintenance tool 30 is inserted and attached. The proximity maintenance tool 30 is inserted and attached to the upper through-hole 24, and after the distal end locking part 15 of the linear locking part 16 of the holder 10 moves to the narrow through-hole 24b, it is again moved to the wide through-hole 24a. This is to prevent it from moving back. The proximity prevention tool 30 is made of synthetic resin, and as shown in FIG. and a contact portion 32 . The right and left end portions of the through-hole inserting portion 31 are formed into tapered surfaces that are inclined toward the front side where the through-hole inserting portion 31 is inserted into the wide through-hole portion 24a. It's getting easier.

The proximity maintenance tool 30 further includes a pair of fitting portions 33, 33 which are notched in a U-shape on the inner side of the pair of left and right tapered surfaces of the through-hole insertion portion 31 and are fitted to the periphery of the wide through-hole portion 24a. They are formed facing each other. Further, when the through-hole inserting portion 31 is forcibly pushed into the wide through-hole portion 24a between the fitting portions 33, 33, the space is reduced to form a recessed space that can reduce the interval between the fitting portions 33. A closed proximity space 34 is provided. Furthermore, after the proximity maintenance tool 30 is once inserted and fixed in the wide penetration portion 24a, both the fitting portions 33, 33 are prevented from approaching each other, and the distance between the fitting portions 33, 33 is kept constant, A proximity prevention part 35 inserted into the proximity space 34 is provided in order to prevent the proximity maintenance tool 30 from coming out of the wide penetration part 24a due to disengagement of the fitting part 33 . The proximity prevention part 35 is formed of a protruding piece protruding toward the proximity space 34 from the proximity space 34 side surface of the proximity prevention piece 36 that rotates around the hinge at one end of the proximity maintenance tool 30 . ing.

The proximity maintenance tool 30 serves as a proximity maintenance means for maintaining a state in which the linear locking portion 16 of the holder 10 is brought close to the curved locking portion 17 side. This proximity maintaining means prevents the linear locking portion 16 of the holder 10 fixed to the fixed body 20 from being unlocked from the upper through hole 24 .

Next, a method of installing the header 40 on the fixed body 20 erected on the floor, which is a structure, using the header fixing device 1 configured as described above will be described.
First, a stand (not shown) is erected on the floor surface, and the fixed body 20 is installed in an upright state by attaching screws to the screw mounting holes that are the fixing portions 21 and screwing them to the stand. In this state, the upper through-hole 24 and the lower through-hole 25 of the fixed body 20 are aligned vertically.

Subsequently, as shown in FIG. 5 , the bent engaging portion 17 of the holder 10 is inserted into the through hole 25 on the lower side of the fixed body 20 . At this time, the retainer 10 is laid horizontally so that the hooking portion 15b of the leading end locking portion 15 of the bent locking portion 17 is vertical, and the lower through hole 25 is inserted from the front side. After that, the holder 10 is rotated 90 degrees in any direction to engage the distal end engaging portion 15 with the peripheral edge of the lower through hole 25 on the back surface of the fixed body 20 . After locking, when the hand is released, the holder 10 is suspended with the tip locking portion 15 of the bent locking portion 17 as a fulcrum with the inner surface of the enclosing portion 13 facing upward. In this manner, the two holders 10 are hung in parallel with each other with a space therebetween in the horizontal direction.

Next, after the two holders 10 are horizontally placed side by side on the main body 22 of the fixed body 20, as shown in FIG. Place. At this time, the header 40 is forcibly pushed down to elastically flex and deform the linear locking portions 16 of the holder 10 to expand the opening 14 and insert it into the enclosing portion 13 . After insertion, the linear locking portion 16 together with the curved locking portion 17 elastically presses and holds the header 40 within the enclosing portion 13 . Accordingly, it is possible to simply hold the header 40 and place it inside the holder 10 to temporarily hold it without holding both holders 10 by hand.

Subsequently, while lifting the header 40 , the holder 10 is rotated upward with the leading end locking portion 15 of the bent locking portion 17 as a fulcrum, and the leading end locking portion 15 of the linear locking portion 16 is moved to the body portion 22 . is inserted into the wide through-hole 24a of the through-hole 24 on the upper side of the . Then, after inserting the distal end engaging portion 15 into the wide through-hole 14, the shaft portion 15a of the distal end engaging portion 15 of the linear engaging portion 16 is moved to the narrow through-hole 24b, and the holder 10 as a whole is moved vertically downward. move to As a result, the hooking portion 15b is hooked and the leading end locking portion 15 is locked to the peripheral edge of the narrow through portion 24b on the back side of the main body portion 22, and the header 40 is temporarily fixed. FIG. 7 shows the state in which the header 40 is temporarily fixed.

After that, the proximity maintenance tool 30 is inserted from the front side into the wide through portion 24a which has become an empty space. At this time, since the through-hole insertion portion 31 of the proximity maintenance tool 30 has tapered surfaces on the left and right sides, the proximity maintenance tool 30 can be smoothly inserted. As a result, when the proximity maintenance tool 30 enters the wide penetrating portion 24a, the pair of right and left fitting portions 33, 33 are elastically fitted to the periphery of the wide penetrating portion 24a. After that, the proximity prevention piece 36 is rotated around the hinge at one end of the proximity maintenance tool 30 to push the proximity prevention portion 35 made of the projecting piece into the proximity space 34 . This prevents the pair of right and left fitting portions 33, 33 from being unintentionally disengaged due to narrowing of the proximity space 34, and the proximity maintenance tool 30 is stably fixed in the wide through portion 24a. be done. Therefore, the front end locking portion 15 of the linear locking portion 16 is prevented from returning from the narrow through portion 24b to the wide through portion 24a and the lock of the front end locking portion 15 is released. This prevents the holder 10 from accidentally coming off the fixed body 20 later.

As a result, the attachment of the holder 10 to the fixed body 20 is completed, and the main pipe portion of the header 40 is formed by the surrounding portion 13 of the holder 10 and the main body portion 22 of the fixed body 20, as shown in FIGS. 41 is permanently fixed to the fixed body 20 so as to surround the entire outer periphery. In this state, the surface contact portion 18 of the bent locking portion 17 of the holder 10 contacts the surface of the body portion 22 as shown in FIG. Moreover, the hexagonal side of the grip portion 43 of the header 40 and the surface of the main body portion 22 of the fixed body 20 are separated by a gap L. As shown in FIG.

Here, the gap L is generated between the grip portion 43 of the header 40 and the surface of the body portion 22 of the fixed body 20 because the bent portion of the bent engaging portion 17 of the holder 10 is positioned on the opening portion 14 side. This is because the header 40 is held in a floating state from the body portion 22 due to the protrusion and the contact of the surface contact portion 18 with the surface of the body portion 22 . In addition, the gap L has a size that does not contact the surface of the body portion 22 at least even when the grip portion 43 rotates and the corner portion of the grip portion 43 comes closest to the surface of the body portion 22 .

After fixing the header 40 to the header fixing device 1 in this way, as shown in FIGS. A tube 50 can be connected.

Next, the operation of the header fixing device 1 of this embodiment will be described.
After the tubular body 50 is connected to the connection port 42a of the branch pipe portion 42 of the header 40, it is often pulled from a remote location. It tends to be swung away from the surface of the main body 22 and tilted. As a result, the branch pipe portion 42 of the header 40 is subjected to a force in the direction in which the pipe body 50 moves away from the main pipe portion 22 about the pipe axis of the header 40 by the pulled pipe body 50 , and the header 40 is pulled away from the main pipe portion 41 . Receives force in the direction of rotation about the tube axis. Here, although the header 40 is permanently fixed to the fixed body 20 by the holder 10, it is possible to rotate around the pipe axis to some extent to change its orientation. On the other hand, the grip portion 43 is separated from the surface of the body portion 22 of the fixed body 20 by the gap L and does not interfere with the body portion 22 . Therefore, the header 40 is not hindered by interference with the main body 22 and rotates by a predetermined angle following the inclination direction of the tubular body 50 . , i.e., the direction in which the tube 50 extends from the branch tube 42 .

As a result, conventionally, since the grasping portion 43 cannot change the rotation angle by contacting the main body portion 22, the direction in which the pulled pipe body 50 extends and the axial center of the branch pipe portion 42 of the header 40 are different. Due to the fact that the direction is different from the previous direction, an excessive force is applied to the connecting portion of the branch pipe portion 42, and there is a risk that the pipe body 50, the connector 51, etc. may be cracked, deformed, or damaged. header fixing device 1 does not cause such a problem.

Further, in the holder 10 , one of the two mounting portions 12 is formed by a bent engagement portion 17 , and the bent engagement portion 17 protrudes toward the opening 14 side and extends to the distal end engagement portion 15 . Since the space between the is bent, the rigidity is large and it is difficult to bend and deform. Further, since the surface contact portion 18 contacts the surface of the main body portion 22 of the fixed body 20, the bent engaging portion 17 fits well into the main body portion 22. As shown in FIG. Therefore, the header 40 can be stably fixed to the fixed body 20 . On the other hand, the retainer 10 has two mounting portions 12, the other of which is formed by a linear engaging portion 16, which is flexurally deformed to expand the narrow opening 14 and hold the holding portion. It allows the insertion of the header 40 into the part 11 .

By the way, both of the two mounting portions 12 of the above-described embodiment have a front end locking portion 15 that passes through the mounted portion 23 of the fixed body 20 and locks onto the rear surface of the main body portion 22 of the fixed body 20. However, the mounting portion 12 is not limited to this. It may be assumed that

Moreover, although the retainer 10 of the above-described embodiment is provided with the surface contact portion 18 on the curved locking portion 17, this may be omitted. In this case, the distal end portion of the bent engaging portion 17 has, for example, the same shape as the distal end engaging portion 15 of the linear engaging portion 16, and the distal end engaging portion 15 of the linear engaging portion 16 In the same way as in , it is conceivable to make it orthogonal to the body portion 22 and lock it in the lower through hole 25 .

Furthermore, the proximity maintenance tool 30 of the above embodiment is inserted into the wide through portion 24a of the fixed body 20 as a separate body, and a pair of fitting portions 33, 33 are fitted to the peripheral edge of the wide through portion 24a. It is not limited to this form and shape. For example, although not shown, a flat cover plate having a slightly larger area than the opening of the wide through portion 24a is applied parallel to the surface of the body portion 22 to cover the opening of the wide through portion 24a. may be prevented from moving from the narrow through portion 24b to the wide through portion 24a. In this case, the cover plate may be formed of a magnetic plate and attached to the surface of the body portion 22, or may be attached by a locking structure, or may be provided integrally with the body portion 22 by a hinge structure. The opening of the wide penetrating portion 24a can also be closed by being bent.

In addition, in the holder 10 of the above embodiment, the linear locking portion 16 is locked to the upper through hole 24 of the fixed body 20, and the curved locking portion 17 is locked to the lower through hole 25. However, the linear engaging portion 16 and the curved engaging portion 17 may be turned upside down and attached to the attached portion 23 of the fixed body 20 . In this case, the distal end engaging portion 15 of the curved engaging portion 17 should be formed parallel to the distal end engaging portion 15 of the linear engaging portion 16 .

In the above embodiment, the header 40 is fixed to the fixed body 20 erected on the floor surface, but the present invention attaches the header 40 to the fixed body 20 installed on the wall surface. Needless to say, it can be similarly applied to the case of fixing.
