Description

Interior panel mounting structure and mounting method

This invention relates to an interior panel mounting structure and mounting method for mounting an interior panel to a building frame.

For example, an interior panel made of gypsum board, cement board, or the like is generally fixed to a base material provided inside the housing with screws (so-called screws) penetrating the interior panel. In many cases, wallpaper etc. are affixed to the interior side surface of the interior panel. In the case of the fixing method using screws as described above, putty is applied to the head surface of the screw after the interior panel is installed. In addition, a smoothing process is performed using sandpaper or the like.

However, in such a conventional general fixing method, since the screw penetrates the interior panel, some post-treatment is necessary for the head of the screw as described above, and in addition, the surface of the interior panel (chamber There is a problem that the inner surface is damaged by the penetration of the screw.

Especially, when the interior panel has a highly functional surface, for example, when the water resistant layer is provided on the indoor side surface, the water resistance is impaired by the penetration of the screw.

Examples of structures for attaching wall panels without damaging the surface include those described in Patent Document 1 and Patent Document 2.

In the technology of Patent Document 1, a circular opening is formed in the back surface of the panel so as to reach the hollow portion, and an elongated deformed angle nut is passed through the circular opening in the hollow portion. It is intended to be inserted. That is, the deformation angle nut is arranged inside the hollow portion, and the mounting bracket disposed on the back surface of the panel is fastened by the deformation angle nut and the bolt.

However, this technique can be applied only to a wall panel having a hollow portion such as an extruded panel.

In Patent Document 2, an end portion of a bolt for attaching a mounting bracket via a nut is formed in an annular shape, and a rod-shaped anchor member is inserted into the annular shape so as to regulate the rotation of the bolt. A wall panel mounting structure is disclosed. That is, after a bolt is inserted and arranged in a hole provided on the back surface of the wall panel, a rod-shaped anchor member is inserted into an anchor insertion hole formed in parallel to the surface of the wall panel so as to be orthogonal to the hole. It is made to engage with the bolt end.

However, in the technique of Patent Document 2, the anchor member must be inserted into the annular portion of the bolt end inside the wall panel that cannot be seen from the outside, so that workability at the construction site is poor. Moreover, since the bolt ends are formed in a relatively large annular shape so that the anchor member can be inserted, application is difficult unless the wall panel has a certain thickness.

Hereinafter, an embodiment of the present invention will be described in detail with reference to the drawings.

In this embodiment, as shown in FIG. 1, a plurality of flat interior panels 1 each having a size of about 1800 mm × 900 mm, for example, are provided on a wall surface on the indoor side of a building (for example, an indoor pool). They are installed side by side. A plurality of metal channel members 2 extending in the horizontal direction are fixed to the wall surface of the building frame, and each interior panel 1 is attached to the channel member 2.

The interior panel 1 of one embodiment has a plate thickness of about 12 mm, for example, and is composed of a cement-based interior board in which particulate aggregates are hardened with a cement-based material, as shown in FIG. Are provided with

skin layers

4 and 5 in which a reinforcing net 3 made of a noncombustible material is embedded. In particular, the skin layer 4 on the surface side that is the indoor side is configured as a water-resistant layer having high water resistance.

FIG. 2 is a perspective view of a main part showing an attachment structure for attaching the interior panel 1 to the metal channel member 2 having an L-shaped cross section. As will be described later, an L-shaped screw member 8 is fixed to a screw mounting portion 7 processed at the end of the interior panel 1, and the screw portion 9 of the screw member 8 passes through the long hole 11 of the channel member 2. The channel member 2 is fixed to the back surface 1a of the interior panel 1 through a nut 10 that is screwed here.

As shown in detail in FIGS. 3 and 4, the screw mounting portion 7 extends from the circular recess 13 opened on the back surface 1 a of the interior panel 1 and from the end surface 1 b of the interior panel 1 on the back surface 1 a of the interior panel 1. The concave groove 14 and the through hole 15 extending between the concave groove 14 and the circular concave portion 13 are composed of three members. The circular recess 13 is formed at a position away from the end of the interior panel 1, for example, the end face 1 b of the interior panel 1 by about several cm. The recess 13 has a diameter of about 10 to 15 mm, for example, and has a flat bottom surface 13a. The concave groove 14 has a groove width corresponding to the diameter of the shaft portion of the screw member 8, for example, about 4 to 5 mm, and extends from the end surface 1 b of the interior panel 1 toward the center of the circular concave portion 13. However, the groove 14 does not reach the recess 13 but extends to a position away from the recess 13 by a predetermined distance. The depth of the concave groove 14 (dimension in the thickness direction of the interior panel 1) basically matches the depth of the concave portion 13. The through hole 15 is extended along the longitudinal direction of the concave groove 14 so as to reach the concave portion 13 from the longitudinal tip 14 a of the concave groove 14. As is apparent from FIG. 4, the through-hole 15 is provided at a height position (position in the thickness direction of the interior panel 1) along the groove bottom portion of the recessed groove 14 and the bottom surface 13 a of the recess 13. It is formed in parallel with the back surface 1a and has a diameter corresponding to the diameter of the shaft portion of the screw member 8, for example, a diameter of about 4 to 5 mm. The bottom surface 14b of the concave groove 14 forms an arc surface that coincides with the peripheral surface of the through hole 15, and the tip 14a of the concave groove 14 also forms a similar arc surface. The screw mounting portion 7 including the concave portion 13, the concave groove 14, and the through hole 15 is secondarily machined after the interior panel 1 is manufactured.

As shown in detail in FIGS. 5 and 6, the screw member 8 fixed to the screw mounting portion 7 is obtained by bending the first straight portion 21 and the second straight portion 22 into an L shape, The threaded portion 9 is processed at the end of the straight portion 22. The shaft portions of the first linear portion 21 and the second linear portion 22 have a diameter that can be inserted into the through hole 15 and the concave groove 14 and that does not cause a gap as much as possible, for example, a diameter of about 4 mm. The second straight portion 22 has a length that allows the screw portion 9 to protrude from the concave groove 14 in a mounting state on the screw mounting portion 7. The first straight portion 21 has such a length that the tip 21 a protrudes into the recess 13 by a predetermined amount when the second straight portion 22 is located at the tip 14 a of the groove 14. Then, as shown in FIG. 6, a concavo-convex shape, more specifically, a plurality of circumferential grooves 23 are provided at the tip portion protruding into the concave portion 13.

As shown in FIGS. 5 and 1, the screw member 8 configured in this manner inserts the first straight portion 21 into the through hole 15 while sliding the second straight portion 22 into the concave groove 14. By doing so, it is arranged in the screw mounting portion 7. In a state where the screw member 8 is pushed in as far as possible, the second straight portion 22 is fitted into the tip 14 a of the groove 14, and the circumferential groove 23 portion of the tip 21 a of the first straight portion 21 is in the recess 13. It will be in the state which protruded (refer to Drawing 8).

In the recess 13, the screw member 8 is disposed, and then the anchor member 25 is inserted from the back surface 1 a side of the interior panel 1 as shown in FIG. 5. As shown in detail in FIG. 7, the anchor member 25 has a cylindrical shape that fits in the recess 13 relatively closely, and has a radial groove portion 26 that receives the tip 21 a portion of the first straight portion 21. I have. In other words, it has a substantially U shape or a substantially C shape having the radial groove portion 26. Further, as will be described later, a circumferential groove 27 is provided on the outer peripheral surface so as to make the adhesion between the inner peripheral surface of the concave portion 13 stronger, and a large number of narrow concave grooves along the axial direction are provided. 28 is formed over the entire circumference. The anchor member 25 may be formed of a hard synthetic resin or the like, but is preferably made of metal, for example, stainless steel in consideration of the nonflammability required for the interior of a building.

FIG. 8 shows a final assembled state, and after inserting the anchor member 25 into the recess 13, the radial groove 26 is filled with an adhesive filler 30. The filler 30 may be a simple adhesive or may contain a particulate material corresponding to the aggregate of the interior panel 1 in the binder. In this manner, the filler 30 filled in the radial groove 26 is solidified, whereby the tip 21 a portion of the first straight portion 21 is coupled to the anchor member 25. In addition, higher adhesive strength is obtained by the circumferential groove 23 provided at the tip 21a portion of the first straight portion 21. At the same time, the anchor member 25 itself is firmly bonded and fixed in the recess 13 by the filler 30. Since the filler 30 spreads between the inner peripheral surface of the recess 13 via the circumferential groove 27 on the outer peripheral surface of the anchor member 25 and the concave groove 28 in the axial direction, high adhesive strength is also obtained.

Further, as shown in FIG. 8, the filler 30 is also filled in the surplus space of the concave groove 14 where the second linear portion 22 of the screw member 8 is located at the tip 14a. The filler 30 may be filled so as to completely fill the surplus space of the concave groove 14, or may fill a part of the surplus space of the concave groove 14, but at least the second linear portion. It is desirable to fill the area around 22. By solidifying the filler 30 in the concave groove 14, the screw member 8 is directly fixed to the interior panel 1, and movement and rattling of the screw member 8 in the screw mounting portion 7 are more reliably prevented. The In order to reduce the amount of the filler 30 used in the concave groove 14, a piece made of a suitable material (for example, metal or hard synthetic resin) is fitted in the concave groove 14 and then the filler 30 is filled. Filling may be performed.

The attachment of the screw member 8 to the screw mounting portion 7 as described above can basically be performed at the construction site of the interior panel 1. After the filler 30 is solidified and the screw member 8 is fixed to the interior panel 1, as shown in FIGS. 8 and 2, the screw portion 9 of the screw member 8 is fitted into the long hole 11 of the channel material 2, Further, by tightening the nut 10, the attachment of the interior panel 1 to the channel material 2 is completed.

As described above, according to the mounting structure of the above embodiment, the mounting can be performed without damaging the water-resistant layer (skin layer 4) on the surface side of the interior panel 1, and the inherent water resistance of the interior panel 1 can be impaired. Absent. Further, the screw member 8 and the anchor member 25 can be attached to the interior panel 1 while visually confirming from the back surface 1a side of the interior panel 1, and good workability can be obtained. The attaching work of the screw member 8 and the like can be performed at the construction site if the screw mounting portion 7 is previously processed on the interior panel 1, and it is difficult to store and transport the panel from which the screw protrudes. Such a problem can be avoided.

Next, FIGS. 9 and 10 show a second embodiment in which the screw member 8 is formed in a T shape to obtain a connecting function between two adjacent interior panels 1. As shown in FIG. 10, the screw member 8 includes a third straight portion 31 that extends on the same straight line as the first straight portion 21 in addition to the first straight portion 21 and the second straight portion 22 of the above-described embodiment. And has a T-shape as a whole. A plurality of circumferential grooves 23 are formed at the distal end of the third linear portion 31, similarly to the distal end 21 a portion of the first linear portion 21.

With respect to the T-shaped screw member 8 as described above, the screw mounting portion 7 of the interior panel 1 located on the lower side of FIG. 9 is basically the same as the above-described embodiment, and has a circular recess 13 and a recess. Three of the groove 14 and the through hole 15 are provided. As described above, the screw member 8 is firmly fixed to the interior panel 1 by the anchor member 25 fitted in the concave portion 13 and the filler 30 filled in the concave portion 13 and the concave groove 14.

On the other hand, in the second interior panel 1A located on the upper side of FIG. 9, two of the circular recess 13 into which the anchor member 25 is fitted and the through hole 15 extending from the end surface 1b toward the center of the recess 13 are provided. The third straight portion 31 protruding upward from the end surface 1 b of the lower interior panel 1 is inserted into the through hole 15. The tip of the third straight portion 31 also projects into the recess 13 and is received in the radial groove 26 of the anchor member 25. The radial groove 26 is finally filled with a filler 30 as in the lower interior panel 1.

As described above, in this embodiment, the T-shaped screw member 8 can be connected to the second interior panel 1A and can be positioned. Note that a plurality of screw members 8 disposed over the entire length of the interior panel 1 are alternately disposed in opposite directions, for example, and the second straight portion 22 having the screw portions 9 is connected to the upper end portion of the lower interior panel 1. It is also possible to arrange it on both the lower end portion of the upper second interior panel 1A.

As described above, one embodiment in which the present invention is applied to a water-resistant cement-based interior board has been described in detail. However, the present invention is not limited to the above-described embodiment. For example, a wooden board, a gypsum board, a stone board, It can be widely applied to various interior panels such as lightweight foamed concrete panels and synthetic resin panels.
