<First embodiment>
First, the assembly maintenance structure of the base material and attachment body of 1st embodiment of this invention is demonstrated based on FIG. 1 thru | or FIG. The assembly maintenance structure of the base material and the attachment body according to the present embodiment exemplifies a structure in which a cylindrical header as a tubular body provided in a water supply or hot water supply piping device is fixed along a wall surface of a building. The base material is a base body fixed to a wall surface or the like, and the attachment body is assembled to the base material and sandwiches, holds and fixes the header with the base material.

  In FIG. 1 to FIG. 4, the assembly maintaining structure 1 </ b> A of the base material and the attachment body includes a base material 10 fixed to the wall surface 60, an attachment body 30 assembled to the base material 10, and a base material 10 and an attachment body 30. And a maintenance member 40 that maintains the assembled state. In the present embodiment, the wall surface 60 is a vertical surface, and the base material 10 is fixed in a vertical state. In the embodiment, the vertical position of each member is represented based on the vertical direction of FIG.

  The base material 10 is formed of a synthetic resin material, a metal material, or the like, and is formed in a strip-like shape having a certain width as shown in FIG. 2, and is fixed to the wall surface 60 at both upper and lower ends, that is, both longitudinal ends. The fixing hole 11 is provided. Steps 12 having a predetermined height in a direction away from the wall surface 60 are provided at positions spaced from the both ends toward the center by a predetermined distance, and the intermediate plate portion 13 between the two step portions 12 is formed of a flat plate. The surface serves as an attachment surface 13 a for attaching the header 70 which is a tubular body together with the attachment body 30.

  A rectangular through hole 14 is provided in the center in the width direction on the upper side of the intermediate plate portion 13 of the base material 10 so as to pass through the front and back surfaces and allow a locking portion 33 of the mounting body 30 described later to pass therethrough. Further, a rectangular moving space 15 having a smaller width is provided below the through hole 14 so as to communicate with the through hole 14. In the moving space 15, the locking portion 33 that has passed through the through hole 14 can move to the attached portion 16 side described below. The through hole 14 and the movement space 15 formed in communication are formed in a convex shape as a whole.

  Further, at the center in the width direction on the lower side of the base material 10, there is provided a long hole-like attached portion 16 that penetrates the front and back surfaces and extends toward the through hole 14 and to which the attachment body 30 is attached. The interval between the through hole 14 and the mounted portion 16 is the same as the interval between a locking portion 33 and a mounting portion 32 described later of the mounting body 30.

  Here, the longitudinal direction of the long hole-shaped attached portion 16 of the base material 10, that is, the length L1 in the vertical direction in FIG. 2, indicates that the attachment portion 32 and the locking portion 33 of the attachment body 30 are attached to the base material 10. As the shaft portion 33 a of the locking portion 33 of the attachment body 30 moves from the position of the through hole 14 to the moving space 15 in a state where it is inserted into the portion 16 and the through hole 14, the attachment portion 32 of the attachment body 30. The shaft portion 32 a is formed to have a length that allows the shaft portion 32 a to move in the attached portion 16.

  As a result, the attachment body 30 has the base 32 within the space of the attachment portion 16 and the range of the through hole 14 and the movement space 15 with the attachment portion 32 inserted into the attachment portion 16 of the base material 10. The through hole 14 of the material 10 and the attached portion 16 can be moved in the arrangement direction, that is, the vertical direction, and the locking portion 33 can be moved closer to or away from the through hole 14 from the moving space 15 side. It has become.

  Next, the attachment body 30 is formed of a rigid body such as a synthetic resin material or a metal material that does not have elasticity, and as shown in FIG. 3, the entire attachment body 30 is formed in a substantially U-shaped plate shape. The main body 31, provided at the lower end portion that is one end portion of the main body 31, and attached to the attachment portion 16 of the base material 10, and provided at the upper end portion that is the other end portion of the main body 31, And an engaging portion 33 that is inserted into the through hole 14 and engages with the moving space 15. Since the attachment body 30 does not have elasticity, the distance between the engaging portion 33 and the attachment portion 32 at both ends of the main body 31 is always constant, and the attachment portion of the base material 10 is elastically deformed and elastically generated. 16 and the moving space 15 are not locked.

  The attachment portion 32 is bent and formed into an L-shaped plate, and extends downward from the lower end portion of the main body 31, and the shaft portion 32a is orthogonal to the shaft portion 32a on the distal end side of the shaft portion 32a. And a hooking portion 32b that is provided so as to protrude in both width directions and hooks to the periphery of the attached portion 16 on the back surface of the base material 10. The shaft portion 32 a is formed in a plate shape having a constant width smaller than the main body 31, and extends downward from the central portion in the width direction of the main body 31. The width dimension of the hooking portion 32 b, that is, the length in the horizontal direction is formed to be approximately the same as that of the main body 31. Further, the hooking portion 32b is composed of a wide portion that is shorter than the longitudinal direction of the rectangular elongated hole-shaped attached portion 16 of the substrate 10 and is longer than the shorter direction.

  On the other hand, the locking portion 33 provided at the upper end portion of the attachment body 30 is extended from the upper end of the main body 31 in the same direction as the plane of the main body 31, and a shaft portion 33a extending from the upper end of the main body 31; A hook portion 33b that is provided on the tip end side of the shaft portion 33a perpendicularly to the shaft portion 33a so as to protrude from the shaft portion 33a in both width directions of the main body 31 and engages with the periphery of the moving space 15 on the back surface of the base material 10. It is configured. The shaft portion 33 a is formed in a plate shape having a constant width smaller than the main body 31, and extends in the longitudinal direction from the central portion in the width direction of the main body 31. The width dimension of the hooking portion 33 b, that is, the length in the horizontal direction is formed to be approximately the same size as the main body 31. The locking portion 33 is formed in this way, and after being inserted into the through hole 14 of the base material 10, when the locking portion 33 moves to the movement space 15 of the base material 10, It is designed to lock on the periphery.

  Next, the maintenance member 40 is fixed to the through hole 14 of the base material 10 to prevent the locking portion 33 of the attachment body 30 from moving from the moving space 15 of the base material 10 to the through hole 14. Yes, as shown in FIG. 4, a through hole insertion portion 41 that is inserted into the through hole 14 of the base material 10 from the front side, and an abutting portion that abuts on the locking portion 33 of the mounting body 30. 42. Further, the maintenance member 40 is formed so as to protrude from a side surface orthogonal to the through hole insertion portion 41, and is provided with a movement space insertion portion 43 to be inserted into the movement space 15 of the base material 10. A contact portion 42 is formed. The contact portion 42 is formed on a flat surface, a convex bulging surface, or the like, but may be formed on other surfaces. The left and right end portions of the through hole insertion portion 41 are formed on tapered surfaces that are inclined toward the front surface side that is inserted into the through hole 14 of the base material 10, and the through hole insertion portion 41 is formed from the front side with respect to the through hole 14. It is easy to insert.

  The maintaining member 40 further includes a pair of opposing fitting portions 44, 44 that are notched in a U shape and are fitted to the periphery of the through hole 14 on the back side of the pair of left and right tapered surfaces of the through hole insertion portion 41. Is formed. Further, when the through hole insertion portion 41 is forcibly pushed into the through hole 14 of the base material 10 between the fitting portions 44, 44, the space is reduced so that the fitting portions 44 can be brought close to each other. A proximity space 45 formed by a recessed space capable of reducing the interval between the joint portions 44 is provided. Further, the fitting portion 44 is inserted into the proximity space 45 to prevent the fitting portions 44 and 44 from approaching each other, and the interval between the fitting portions 44 and 44 is kept constant. A proximity preventing portion 47 is provided that prevents the maintenance member 40 from being detached and pulled out of the through hole 14. A plurality of engaging grooves 45 a are formed in the horizontal direction on the side surface of the adjacent space 45. The proximity preventing portion 47 is formed of a projecting piece projecting toward the proximity space 45 on the surface on the proximity space 45 side of the proximity preventing piece 46 that rotates about the hinge at one end of the maintenance member 40. In addition, small protrusions 47a that are elastically engaged with the engaging grooves 45a in the adjacent space 45 are formed in the horizontal direction on both side surfaces of the protruding piece.

  The moving space insertion portion 43 is inserted into the moving space 15 of the base material 10, and the contact portion 42 at the tip of the engaging portion 33 of the attachment body 30 inserted into the moving space 15 of the base material 10. By contacting the upper surface of the shaft portion 33 a, the locking portion 33 is stably held without rattling inside the through hole 14 and the moving space 15 of the base material 10. Since 33 does not have to be pulled out from the through hole 14 at least after being locked in the through hole 14 and the moving space 15 of the base material 10, the moving space insertion portion 43 is not necessarily provided. Further, when the maintaining member 40 is formed to have a width substantially the same as the side length in the vertical direction of the rectangular through hole 14, that is, the short side length, it is tightly accommodated in the through hole 14 and stably held. However, the dimensions are not necessarily the same.

Next, a method of assembling the attachment body 30 to the base material 10 using the assembly maintaining structure 1A between the base material and the attachment body of the present invention will be described.
First, screws are attached to the pair of upper and lower fixing holes 11 of the base material 10, and the base material 10 is set in a vertically long state and directly fixed to the wall surface 60 of the building as a structure. In this state, the attached portion 16 and the through hole 14 of the base material 10 are aligned in the vertical direction. Next, as shown in FIG. 5 (a), the attachment body 30 is tilted sideways so as to be in a horizontal posture, and the protruding direction from the shaft portion 32a of the engaging portion 32b of the lower attachment portion 32 is set to the through hole 14 and the attachment target. It is set as the attitude | position along the alignment direction with the part 16, ie, the longitudinal direction of the to-be-attached part 16 of a long hole shape. In this state, the attachment portion 32 can be inserted into the attached portion 16 from the front side. Therefore, when the mounting portion 32 is inserted into the mounted portion 16, as shown in FIG. 5 (b), the main body 31 is rotated 90 degrees clockwise, so that the mounting portion 32 and the locking portion 33 of the mounting body 30 are rotated. The orientation of the attachment body 30 is displaced in a direction in which the alignment direction intersects the alignment direction of the attached portion 16 of the base material 10 and the through hole 14. When the posture of the attachment body 30 is displaced, the attachment portion 32 is in a state of being engaged with the periphery of the attachment portion 16 on the back surface of the base material 10 at both side portions thereof.

  Next, as shown in FIGS. 5C and 5D, the locking portion 33 on the upper side of the attachment body 30 is inserted into the through hole 14 on the upper side of the base member 10 and is passed therethrough. At this time, since the interval between the locking portion 33 and the attachment portion 32 of the attachment body 30 coincides with the interval between the through hole 14 of the base material 10 and the attachment portion 16, the attachment body 30 is not elastically deformed. The locking portion 33 can be inserted and passed through the through hole 14 as it is. When the locking portion 33 is inserted into the through hole 14, as shown in FIGS. 5E and 5F, the entire attachment body 30 is moved vertically downward. Then, since the moving space 15 is formed below the through hole 14, the shaft portion 33 a of the locking portion 33 of the attachment body 30 moves to the moving space 15 side.

  Here, as described above, the longitudinal direction of the elongated hole-like attached portion 16 of the base material 10, that is, the length in the vertical direction in FIG. 10, when the shaft portion 33 a of the locking portion 33 of the mounting body 30 moves from the position of the through hole 14 to the moving space 15, the shaft portion 32 a of the mounting portion 32 is also mounted. It is formed in a length that allows it to move within 16. For this reason, while the shaft portion 33a of the locking portion 33 of the attachment body 30 is moving to the moving space 15, the attachment portion 32 comes into contact with the lower end of the attached portion 16 so that the attachment body 30 is further downward. It does not prevent you from moving. Thus, when the shaft portion 33 a of the locking portion 33 of the mounting body 30 moves into the moving space 15, the wide hooking portion 33 b of the locking portion 33 is hooked and the locking portion 33 is a moving space on the back surface of the base material 10. 15 is engaged with the periphery.

  When the locking portion 33 of the attachment body 30 moves to the movement space 15, the inside of the through hole 14 becomes a vacant space, and the maintenance member 40 is inserted into the space from the front side from the through hole insertion portion 41 side. At this time, since the through hole insertion portion 41 has a pair of tapered surfaces on the left and right, the maintenance member 40 can be smoothly inserted. Thereby, when the maintenance member 40 enters the through hole 14, the pair of left and right fitting portions 44, 44 facing each other are elastically fitted to the periphery of the through hole 14 of the base material 10. Thereafter, the proximity preventing piece 46 is rotated around the hinge at one end of the maintaining member 40 to push the proximity preventing portion 47 formed of a protruding piece into the proximity space 45. As a result, the proximity prevention portion 47 is in a state of being prevented from coming off by the small protrusion 47a on the side surface engaging with the engagement groove 45a in the proximity space 45, and the right and left sides of the through-hole insertion portion 41 are reduced by the narrowing of the proximity space 45. The fitting of the pair of fitting portions 44, 44 is prevented from being inadvertently released. For this reason, since the maintenance member 40 is stably and reliably fixed in the through hole 14 of the base material 10, the locking portion 33 of the attachment body 30 returns from the moving space 15 to the inside of the through hole 14 to lock the locking portion 33. Can be prevented from being released, and the attachment body 30 can be reliably prevented from being detached from the base material 10 after being once assembled. FIG. 6 shows a state where the attachment of the attachment body 30 to the base material 10 is completed.

Next, a method of installing and fixing the header 70 that is a tubular body in a horizontal state along the wall surface 60 of the building by the assembly maintaining structure 1A between the base material and the attachment body of the present embodiment will be described.
In order to install the header 70, the two base materials 10 are fixed to the wall surface 60 in parallel in the horizontal direction at intervals, and the attachment portions 32 of the attachment bodies 30 are respectively attached to the attachment portions 16 of the respective base materials 10. After the posture shown in (a), the insertion direction of the mounting portion 32 and the locking portion 33 is inserted in a posture along the alignment direction of the mounted portion 16 and the through hole 14 of the base material 10, the posture of the main body 31 is changed. Change 90 degrees. If the hand is released in this state, the attachment body 30 will be shown in FIG. 7 (a) with the attachment portion 32 locked to the attachment portion 16 of the substrate 10 and the curved inner surface facing upward with the attachment portion 32 as a fulcrum. ) As shown in (). Therefore, as shown in FIG. 7B, the header 70 is horizontally placed on the curved inner surface that is the inside of both attachment bodies 30. Thereby, the header 70 is supported in the main body 31 of the attachment body 30. Therefore, when the header 70 is placed on both the attachment bodies 30, it is not necessary to hold both the attachment bodies 30 by hand, and only the header 70 is gripped and placed inside the attachment body 30. Can be retained.

  Next, when the headers 70 are placed horizontally on both attachment bodies 30, the attachment body 30 is rotated upward with the attachment portion 32 as a fulcrum, and the locking portion 33 on the other end side is placed on the upper side of the substrate 10. Insert into the through hole 14. Then, the entire attachment body 30 is pushed down while the shaft portion 33a of the locking portion 33 is moved toward the lower moving space 15 in the inserted state. Thereafter, the maintenance member 40 is inserted and fixed in the through-hole 14 from the front side to complete the assembly of the attachment body 30 to the base material 10, and as a result, as shown in FIG. It is held and fixed so as to be surrounded by the material 10 and the attachment body 30.

Next, the operation of the assembly maintaining structure 1A between the base material and the attachment body of the present embodiment will be described.
In the maintenance structure of the present embodiment, when the attachment body 30 is assembled to the base material 10, the attachment portion 32 of the attachment body 30 is inserted into the attached portion 16 of the base material 10 and then the locking portion 33 of the attachment body 30. Is inserted into the through hole 14 of the base material 10 and further moved to the moving space 15 side to be engaged with the periphery of the moving space 15 on the back surface of the base material 10, and then the maintenance member 40 is inserted into the vacant through hole 14. Thus, the attachment portion 30 can be easily and reliably assembled to the base material 10 by preventing the locking portion 33 from moving to the through hole 14 and returning by the one-touch operation for fixing. Therefore, the troublesome labor of attaching and fixing a screw by turning a tool such as a screwdriver as in the prior art is unnecessary, and the attachment body 30 can be assembled to the base material 10 with good workability.

  Further, since the attachment body 30 is formed of a synthetic resin material, a metal material, or the like that does not have elasticity, the interval between the engaging portion 33 and the attachment portion 32 at both ends of the main body 31 is always constant, and the attachment body 30 is elastically deformed. Therefore, it is not locked to the moving space 15 and the attached portion 16 of the base material 10 by the elastic force. Therefore, the interval between the locking portion 33 and the mounting portion 32 of the attachment body 30 is elastically enlarged or reduced at any moment, so that the locking portion 33 of the mounting body 30 is pulled out of the through hole 14 of the base material 10, It is possible to reliably prevent the attachment portion 32 of the attachment body 30 from being detached from the attached portion 16 of the base material 10 and coming off the base material 10 and falling.

  When the attachment portion 32 of the attachment body 30 is attached to the attachment portion 16 of the base material 10, the arrangement direction of the attachment portion 32 and the locking portion 33 is changed to the attachment portion 16 of the base material 10 and the through hole 14.
