It is composed of a maintenance member 40 that maintains the assembled state with the above. 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 made of a synthetic resin material, a metal material, or the like, and is formed in the shape of a strip plate having a constant width as shown in FIG. The fixing hole 11 is provided. Step portions 12 having a predetermined height in the direction away from the wall surface 60 are provided at positions separated from both end portions 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 thereof is a mounting surface 13a to which the header 70, which is a tubular body, is mounted together with the mounting body 30.

A rectangular through hole 14 is provided at the center in the width direction on the upper side of the intermediate plate portion 13 of the base material 10 so as to penetrate the front and back surfaces and allow the locking portion 33 of the mounting body 30, which will be described later, to pass through. Further, below the through hole 14, a rectangular moving space 15 having a width smaller than this is provided 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 be moved to the side to be attached to the portion 16 to be described later. The through hole 14 and the moving space 15 formed in communication with each other are formed in a convex shape as a whole.

Further, in the center of the lower portion of the base material 10 in the width direction, an elongated hole-shaped attachment portion 16 that penetrates the front and back surfaces, extends toward the through hole 14, and the attachment body 30 is attached is provided. The distance between the through hole 14 and the mounted portion 16 is the same as the distance between the locking portion 33 and the mounting portion 32, which will be described later, of the mounting body 30.

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

As a result, the mounting body 30 is based on the mounting portion 32 in the space of the mounted portion 16 and within the range of the through hole 14 and the moving space 15 in a state where the mounting portion 32 is inserted into the mounted 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 alignment direction, that is, in the vertical direction, and the locking portion 33 can be approached or separated from the moving space 15 side with respect to the through hole 14. It has become.

Next, the mounting body 30 is formed of a rigid body such as a synthetic resin material or a metal material having no elasticity, and as shown in FIG. 3, the entire mounting body 30 is formed in a substantially U-shaped plate shape and has a substantially U-shaped plate shape. The main body 31, the mounting portion 32 provided at the lower end portion which is one end of the main body 31 and attached to the attached portion 16 of the base material 10, and the upper end portion which is the other end of the main body 31 are provided and the base material 10 It has a locking portion 33 which is inserted through the through hole 14 of the above and engages with the moving space 15. Since the mounting body 30 does not have elasticity, the distance between the locking portions 33 at both ends of the main body 31 and the mounting portion 32 is always constant, and the mounting portion of the base material 10 is elastically deformed and elastically deformed. It is not locked to 16 and the moving space 15.

The mounting portion 32 is formed to be bent in an L-shaped plate shape, and has a shaft portion 32a extending downward from the lower end portion of the main body 31 and a shaft portion 32a to the main body 31 orthogonal to the shaft portion 32a on the tip end side of the shaft portion 32a. It is composed of an engaging portion 32b which is provided so as to project in both width directions and engages with the peripheral edge of the attached portion 16 on the back surface of the base material 10. The shaft portion 32a is formed in a plate shape having a constant width smaller than that of 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 engaging portion 32b, that is, the length in the horizontal direction is formed to be substantially the same as that of the main body 31. Further, the engaging portion 32b is composed of a wide portion formed so as to be shorter in the longitudinal direction and longer in the lateral direction than the rectangular elongated hole-shaped attached portion 16 of the base material 10.

On the other hand, the locking portion 33 provided at the upper end portion of the mounting body 30 extends from the upper end of the main body 31 in the same direction as the plane of the main body 31, and includes a shaft portion 33a extending from the upper end of the main body 31. From the engaging portion 33b, which is provided on the tip end side of the shaft portion 33a so as to project from the shaft portion 33a in both width directions of the main body 31 at right angles to the shaft portion 33a and engages with the peripheral edge of the moving space 15 on the back surface of the base material 10. It is configured. The shaft portion 33a is formed in a plate shape having a constant width smaller than that of 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 engaging portion 33b, that is, the length in the horizontal direction is formed to be substantially the same as that of 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 it moves to the moving space 15 of the base material 10, the moving space 15 on the back surface of the base material 10 It is designed to be locked to the peripheral edge.

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 mounting body 30 from moving from the moving space 15 of the base material 10 to the through hole 14. Yes, it is made of synthetic resin, and as shown in FIG. 4, a through-hole insertion portion 41 inserted into the through-hole 14 of the base material 10 from the front side and an abutting portion that abuts the locking portion 33 of the mounting body 30. It has 42 and. Further, the maintenance member 40 is provided with a moving space insertion portion 43 that is formed so as to project on a side surface orthogonal to the through hole insertion portion 41 and is inserted into the moving space 15 of the base material 10, and the tip thereof is provided with the moving space insertion portion 43. The 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 another surface. The left and right end portions of the through hole insertion portion 41 are formed on tapered surfaces that are inclined toward the front side to be 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.

Further, the maintenance member 40 has a pair of facing fitting portions 44, 44 which are notched in a U shape and are fitted to the peripheral edge of the through hole 14 on the inner side of the pair of left and right tapered surfaces of the through hole insertion portion 41. It 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 two fitting portions 44 and 44, the space is reduced so that both fitting portions 44 can be brought close to each other, that is, both fittings. A proximity space 45 formed by a recessed space in which the distance between the joint portions 44 can be reduced is provided. Further, it is inserted into the proximity space 45 to prevent the fitting portions 44, 44 from approaching each other and keep the distance between the fitting portions 44, 44 constant, so that the fitting portions 44 can be fitted. A proximity prevention portion 47 is provided to prevent the maintenance member 40 from coming off from the through hole 14. A plurality of engaging grooves 45a are formed in the horizontal direction on the side surface of the proximity space 45. The proximity prevention portion 47 is formed of a protrusion projecting toward the proximity space 45 on the surface of the proximity prevention piece 46 that rotates around the hinge at one end of the maintenance member 40 on the approach space 45 side. On both side surfaces of the protrusions, small protrusions 47a that elastically engage with the engagement grooves 45a in the proximity space 45 are formed in the horizontal direction.

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 is the locking portion 33 of the mounting body 30 inserted into the moving space 15 of the base material 10. By contacting the upper surface of the shaft portion 33a, the locking portion 33 is stably held inside the through hole 14 of the base material 10 and the moving space 15 without rattling, but the locking portion of the mounting body 30 is held. Since the 33 does not have to be removed 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 does not necessarily have to be provided. Further, when the maintenance member 40 is formed to have a width substantially the same as the vertical side length, that is, the short side length of the rectangular through hole 14, it is tightly accommodated in the through hole 14 and stably held. However, they do not necessarily have to have substantially the same dimensions.

Next, a method of assembling the attachment body 30 to the base material 10 by the assembly maintenance structure 1A of the base material and the attachment body of the present invention will be described.
First, screws are attached to a pair of upper and lower fixing holes 11 of the base material 10, and the base material 10 is directly fixed to the wall surface 60 of the building, which is a structure, in a vertically elongated state. In this state, the attached portion 16 of the base material 10 and the through hole 14 are aligned in the vertical direction. Next, as shown in FIG. 5A, the mounting body 30 is tilted sideways to take a horizontal posture, and the protruding direction of the engaging portion 32b of the lower mounting portion 32 from the shaft portion 32a is the through hole 14 and the mounted portion. The posture is such that it is aligned with the portion 16, that is, along the longitudinal direction of the elongated hole-shaped attached portion 16. In this state, the mounting portion 32 can be inserted into the mounted portion 16 from the front side. Therefore, when the mounting portion 32 is inserted into the mounted portion 16, the main body 31 is rotated 90 degrees clockwise as shown in FIG. 5 (b), and the mounting portion 32 and the locking portion 33 of the mounting body 30 are rotated. The posture of the mounting body 30 is displaced in a direction in which the alignment direction of the base material 10 intersects with the alignment direction of the mounted portion 16 of the base material 10 and the through hole 14. When the posture of the mounting body 30 is displaced, the mounting portion 32 is in a state of being locked to the peripheral edge of the mounted portion 16 on the back surface of the base material 10 on both side portions thereof.

Next, as shown in FIGS. 5 (c) and 5 (d), the locking portion 33 on the upper side of the mounting body 30 is inserted into the through hole 14 on the upper side of the base material 10 and passed through. At this time, since the distance between the locking portion 33 and the mounting portion 32 of the mounting body 30 coincides with the distance between the through hole 14 of the base material 10 and the mounted portion 16, the mounting body 30 is not elastically deformed. The locking portion 33 can be inserted into the through hole 14 and passed through as it is. After the locking portion 33 is inserted into the through hole 14, the entire mounting body 30 is moved vertically downward as it is, as shown in FIGS. 5 (e) and 5 (f). Then, since the moving space 15 is communicatively formed below the through hole 14, the shaft portion 33a of the locking portion 33 of the mounting body 30 moves to the moving space 15 side.

Here, as described above, the length of the elongated hole-shaped attached portion 16 of the base material 10 in the longitudinal direction, that is, the vertical direction in FIG. 2 is such that the mounting portion 32 and the locking portion 33 of the mounting body 30 are the base materials, respectively. When the shaft portion 33a of the locking portion 33 of the mounting body 30 moves from the position of the through hole 14 to the moving space 15 in the state of being arranged on the back surface side of the mounting body 10, the shaft portion 32a of the mounting portion 32 is also mounted. It is formed to a length that allows it to move within 16. Therefore, while the shaft portion 33a of the locking portion 33 of the mounting body 30 is moving to the moving space 15, the mounting portion 32 comes into contact with the lower end of the mounted portion 16 and the mounting body 30 extends below it. It does not happen that you are prevented from moving. In this way, when the shaft portion 33a of the locking portion 33 of the mounting body 30 moves into the moving space 15, the wide engaging portion 33b of the locking portion 33 is engaged and the locking portion 33 is the moving space on the back surface of the base material 10. Locks to the periphery of 15.

When the locking portion 33 of the mounting body 30 moves to the moving space 15, the through hole 14 becomes an empty space, so 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 formed on the left and right, the maintenance member 40 can be smoothly inserted. As a result, 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 peripheral edge of the through hole 14 of the base material 10. After that, the proximity prevention piece 46 is rotated around the hinge at one end of the maintenance member 40 to push the proximity prevention portion 47 made of the projecting pieces into the proximity space 45. As a result, in the proximity prevention portion 47, the small ridges 47a on the side surface engage with the engagement groove 45a in the proximity space 45 to prevent the proximity space 45 from coming off, and the proximity space 45 narrows to the left and right of the through hole insertion portion 41. It is possible to prevent the pair of fitting portions 44, 44 from being inadvertently released from fitting. Therefore, since the maintenance member 40 is stably and surely fixed in the through hole 14 of the base material 10, the locking portion 33 of the mounting body 30 returns from the moving space 15 into the through hole 14 and the locking portion 33. It is possible to prevent the locking body 30 from being released, and it is surely prevented that the mounting body 30 is detached from the base material 10 once it is assembled. FIG. 6 shows a state in which the attachment body 30 is assembled to the base material 10.

Next, a method of installing and fixing the header 70, which is a tubular body, in a horizontal state along the wall surface 60 of the building by the assembling maintenance structure 1A of the base material and the mounting body of the present embodiment will be described.
In order to install the header 70, two base materials 10 are horizontally juxtaposed and fixed to the wall surface 60 at intervals, and then the mounting portion 32 of the mounting body 30 is attached to the mounted portion 16 of each base material 10 in FIG. After inserting the posture shown in (a) in a posture in which the mounting portion 32 and the locking portion 33 are aligned 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. When the hand is released in this state, the mounting body 30 is in a state where the mounting portion 32 is locked to the mounted portion 16 of the base material 10, with the mounting portion 32 as a fulcrum and the curved inner surface facing upward in FIG. 7 (a). ) Shows that it is in a hanging state. Therefore, as shown in FIG. 7 (b), the header 70 is placed horizontally on the curved inner surface inside both the mounting bodies 30. As a result, the header 70 is supported in the main body 31 of the mounting body 30. Therefore, when mounting the header 70 on both mounting bodies 30, it is not necessary to hold both mounting bodies 30 by hand, and only the header 70 is simply gripped and mounted inside the mounting body 30 temporarily. Can be retained.

Next, when the header 70 is placed horizontally on both mounting bodies 30, the mounting body 30 is rotated upward with the mounting portion 32 as a fulcrum, and the locking portion 33 on the other end side is on the upper side of the base material 10. It is inserted into the through hole 14. Then, in the inserted state, the shaft portion 33a of the locking portion 33 is moved to the lower moving space 15 side while pushing down the entire mounting body 30. After that, the maintenance member 40 is inserted and fixed in the through hole 14 from the front side to complete the assembly of the mounting body 30 to the base material 10, whereby the header 70 is the base as shown in FIG. 7 (c). It is held and fixed so as to be surrounded by the material 10 and the mounting body 30.

Next, the operation of the assembly maintenance 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 mounting body 30 is assembled to the base material 10, the mounting portion 32 of the mounting body 30 is inserted into the mounted portion 16 of the base material 10, and then the locking portion 33 of the mounting body 30 is inserted. Is inserted into the through hole 14 of the base material 10 and further moved to the moving space 15 side to be locked to the peripheral edge 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. The mounting body 30 can be easily and surely 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 of fixing. Therefore, it is not necessary to turn a tool such as a screwdriver to attach and fix the screw as in the conventional case, and the attachment body 30 can be assembled to the base material 10 with good workability.

Further, since the mounting body 30 is made of a synthetic resin material, a metal material, or the like having no elasticity, the distance between the locking portions 33 at both ends of the main body 31 and the mounting portion 32 is always constant, and the mounting 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 distance between the locking portion 33 of the mounting body 30 and the mounting portion 32 may be elastically expanded or contracted, and the locking portion 33 of the mounting body 30 may be pulled out from the through hole 14 of the base material 10. It is possible to reliably prevent the mounting portion 32 of the mounting body 30 from being detached from the mounted portion 16 of the base material 10 and the mounting body 30 from being detached from the base material 10 and falling.

Then, when the mounting portion 32 of the mounting body 30 is mounted on the mounted portion 16 of the base material 10, the mounting direction of the mounting portion 32 and the locking portion 33 is aligned with the mounted portion 16 of the base material 10 and the through hole 14. Since the posture of the main body 31 is formed so as to be displaceable in the direction along and the crossing direction with respect to the arrangement direction of the above, the posture of the main body 31 can be displaced simply by inserting the mounting portion 32 of the mounting body 30. The mounting portion 32 of the mounting body 30 can be easily mounted and locked to the mounted portion 16 of the base material 10 from the front side of the base material 10.

In addition, the attached portion 16 of the base material 10 is formed in an elongated hole shape, and the attached portion 32 of the attachment body 30 is a shaft portion 32a extending from the main body 31 and the attached portion 16 on the back surface of the base material 10.
