Description

  The present invention relates to a mounting structure for an outer wall surface material.

  For example, as shown in FIGS. 6 (a) and 6 (b), the outer side wall material of the ceramic industry is latched on the attachment side 52 as shown in FIGS. At the same time as attaching the object 53, a bottomed recess 54 is provided on the back surface of the outer wall surface material 51, and the hanging portion 55 of the latch 53 is inserted into the bottomed recess 54 of the outer wall surface material 51 and slides upward. There is something that is hooked and attached.

  The latch 53 includes a conical portion 55b whose diameter increases outwardly on the tip side of the cylindrical portion 55a.

  Further, as shown in FIG. 6C, the bottomed recess 54 uses a router bit 15 provided with a conical portion 15b whose diameter increases toward the tip side on the tip side of the cylindrical portion 15a. 15 is lowered while grinding to a predetermined depth position of the meat of the outer wall surface material 51 as indicated by an arrow, and is ground linearly by a predetermined dimension in one direction while maintaining the depth position from that position. After that, it is formed so as to reciprocate to return to the same route and to be separated from the outer wall surface material 51, as shown in FIGS. 54a is an insertion portion for inserting the hook portion 55 of the latch 53, and the upper end portion 54b is a receiving portion that is narrower than the insert portion 54a and receives the hook portion 55 of the latch 53, and an intermediate portion 54c that connects them is inserted. Portion 54a and receiving portion 54b And a slide unit for fault, opening of the sliding portion 54c has a width dimension is in the same size throughout receiving portion 54b from the insertion portion 54a.

Then, the outer wall surface material 51 is attached to the attachment side 52 by attaching a plurality of latches 53 to the attachment side 52 so as to be spaced from each other. A bottom recess 54 is provided, and as shown in FIGS. 7 (a) to (d) and FIGS. 8 (a) to (e), each hanging portion 55 is inserted into an insertion portion 54a of each bottomed recess 54. The insertion is performed by sliding the slide portion 54c to be received by the receiving portion 54b.

  However, in the mounting structure as described above, the receiving portion is arranged so that the outer wall surface material 51 does not rattle in the left-right direction in a state where the hanging portion 55 of the latch 53 is received by the receiving portion 54b of the bottomed recess 54. 54b is formed with a small diameter, and the width of the opening of the slide portion 54c in the bottomed recess 54 is set to a constant size that is the same or substantially the same as the diameter of the cylindrical portion 55a of the hanging portion 55 over the entire length. Therefore, in the process of attaching the outer wall surface material 51 in which the hanging portion 55 of each latch 53 is slid toward the receiving portion 55b in the sliding portion 54c of each bottomed recess 54, FIG. ), When the outer wall surface material 51 tries to be rotationally displaced in the in-plane direction, the hook portion 55 of the latch 53 is caught by the slide portion 54c of the bottomed recess 54 and cannot move. It is impossible to go the hanging part 55 of the object 53 smoothly slide into receiving portion 54b of the bottomed recess 54.

  Further, the outer wall surface material 51 needs to be attached to the attachment side 52 so as not to be loose in the front-rear direction. However, as described above, the width dimension of the slide portion 54c of the bottomed recess 54 is inserted. In the range from the portion 54a to the receiving portion 54b, the play in the depth direction of the bottomed recess 54 is sufficient when the hook portion 55 of the latch 53 is slid on the slide portion 54c of the bottomed recess 54. There is also a problem that the hook 55 of the latch 53 cannot be smoothly slid to the receiving portion 54b of the bottomed recess 54.

  Further, as shown in FIGS. 6 (b) and 8, when the outer wall surface material 51 and the attachment side 52 are bonded with the adhesive 56, the hook portion 55 of the latch 53 is thus provided with a bottomed recess. Since the play in the depth direction of the bottomed recess 54 when sliding on the slide portion 54c of 54 cannot be ensured sufficiently, the hook 55 of the latch 53 is moved to the slide of the bottomed recess 54. In the process of sliding 54c to the receiving portion 54b side, the outer wall surface material 51 and the attachment side 52 are in close proximity or in contact with each other, the adhesive 56 is greatly sheared and spreads, and the outer wall surface material 51 is thinned. There is also a problem that the attachment side 52 is hard to be firmly bonded with the adhesive 56.

  In view of the above-described problems, the present invention can smoothly shift the hook portion of the latch inserted into the insertion portion of the bottomed recess to the receiving portion through the slide portion, and the outer wall surface to the mounting side. It is an object of the present invention to provide an outer wall material mounting structure capable of facilitating the mounting of a material.

The above-described problem is that a plurality of latches for hooking the face material are provided at intervals on the mounting side for attaching the outer wall surface material,
A corresponding number of bottomed recesses are provided on the back surface of the outer wall material to hang the hanging portion of the latch,
Each bottomed recess has an insertion part for inserting the latch part of the latch at the lower end side, and a receiving part for receiving the latch part of the latch with a narrower width than the insertion part at the upper end side. The connecting middle part consists of a slide part that connects the insertion part and the receiving part,
The slide part is formed so that its width dimension is gradually reduced from the insertion part to the receiving part,
The hanging part of each latch is inserted into the insertion part of each bottomed recess of the outer wall surface material, the sliding part is slid and received by the receiving part, and the outer wall surface material is attached to the mounting side. This is solved by the mounting structure of the outer wall surface material characterized in that (first invention).

  In this structure, the slide portion of the bottomed recess is formed so that its width dimension gradually decreases from the insertion portion to the receiving portion. The outer wall material can have a play in the left-right direction with respect to the mounting side until the part is slid and received by the receiving part, and the play causes the outer wall material to slightly rotate and displace in the in-plane direction. Even so, the latching part of the latching object will not be caught by the sliding part of the bottomed recess and will not move, and the latching part of each latching object will slide smoothly to the receiving part of each bottomed recess. Thus, it is possible to easily attach the outer wall surface material to the attachment side.

  In the first invention, in a state in which the hooking portions of the respective latches are received by the receiving portions of the respective bottomed recesses, the outer wall surface material is prevented from coming off outward by the engagement of the hooking portions and the receiving portions. (2nd invention).

  In this case, in the bottomed recess, a structure in which the insertion portion and the receiving portion are connected to each other by a slide portion with a sufficient length interval can be used to prevent the outer wall material from being covered with the hook portion. It can be enlarged, and the outer wall material can firmly prevent the outer wall material from coming off at the receiving part, and the outer wall material can be firmly attached. Even so, even if the length dimension of the slide part is increased in this way, as described above, each slide part is formed so that its width dimension gradually decreases from the insertion part to the receiving part. Further, it is possible to easily attach the outer wall surface material to the attachment side.

  In the second invention, in the process of sliding the side part of the hanging part of each latch and / or the side part sandwiching the slide part of the bottomed recess into the side of the receiving part in the sliding part, It is formed on the slope that gradually reduces the size of the play between the outer wall surface material and the mounting side in the inner and outer direction, and the outer wall surface material plays outward on the mounting side while the hanging portion is received by the receiving portion. It is good to be closely connected (third invention).

  In this case, the latching portion of the latching object has a bottomed recess due to the combined synergistic action of the slope and the slide portion formed so that the width dimension is gradually reduced from the insertion portion to the receiving portion. It is possible to ensure sufficient play in the depth direction of the bottomed recess in the process of sliding to the receiving part side at the sliding part of the place, and the hanging part of the latch to the receiving part of the bottomed recess It can slide smoothly, and also from this surface, the attachment of the outer wall surface material to the attachment side can be facilitated.

  In the third invention, in the mounted state, the outer wall surface material and the mounting side may be bonded with an adhesive interposed therebetween (fourth invention). In this case, the outer wall surface material and the mounting side are separated from each other by using play in the inner and outer directions in the process in which the latching portion of the latching object slides toward the receiving portion side of the bottomed recess. Thus, the adhesive can be prevented from being sheared and spread and thinned, and the outer wall surface material and the attachment side can be firmly bonded to each other with the adhesive.

  Since the present invention is as described above, the hanging portion of the latch inserted into the insertion portion of the bottomed recess can be smoothly transferred to the receiving portion through the slide portion, and the outer wall surface to the mounting side The material can be easily installed.

  Next, the best mode for carrying out the present invention will be described with reference to the drawings.

  In the structure of the embodiment shown in FIGS. 1 to 5, the outer wall surface material 1 is a ceramic-based surface material, and as shown in FIG. 5 and FIG.

A conical portion 5b extending from the peripheral wall of the portion 5a is provided, and an inner flange portion 3a for receiving the head of the screw 4 is provided at the base end portion of the cylindrical portion 5a. The cylindrical portion 5a The conical part 5b constitutes the hanging part 5 of the latch 3, and the screw 4 is passed through the through hole 3b surrounded by the inner flange 3a. It is attached.

  On the other hand, as shown in FIG. 5 (b), a corresponding number of bottomed recesses 6 for hanging the hanging parts 5 of the above-described latches 3. Is provided. As shown in FIG. 1 (b), each bottomed recess 6 has a shape on the recess opening side of a circle on the lower end side and a circle on the upper end side having a smaller diameter than these two circles. It has a shape connected with a wire, the lower end side 6a is a circular insertion part for inserting the hanging part 5 of the latch 3 and the upper end 6b is a receiving part for receiving the hanging part 5 of the latch 3. The intermediate portion 6c connecting them is a slide portion that connects the insertion portion 6a and the receiving portion 6b, and the slide portion 6c is formed so that its width dimension gradually decreases from the insertion portion 6a to the receiving portion 6b. The hook portion 5 of the latch 3 is inserted into the insertion portion 6a of the bottomed recess 6, and the slide portion 6c is slid to be received by the receiving portion 6b.

  In the present embodiment, the receiving portion 6b of the bottomed recess 6 has a peripheral surface 7 formed on the inclined surface so as to extend in the depth direction, and the conical portion 5b of the latch 3 is along the inclined surface 7. As a result, the outer wall surface material 1 is brought into close contact with the styrene board 2c on the mounting side, and the outer wall surface material 1 is prevented from coming off in the outward direction, that is, in the outdoor direction, thereby forming a fixed state without rattling in the indoor and outdoor directions. It is made to be done.

  Further, the left and right side surfaces 8 and 8 are formed on the inclined surface so that the slide portion 6c of the bottomed recess 6 also extends in the depth direction, and the cone of the latch 3 in the slide portion 6c of the bottomed recess 6 is formed. The passage 5b is allowed to pass, and the slopes 8 and 8 and the slide portion 6c are gradually reduced in width from the insertion portion 6a to the receiving portion 6b as described above. In the process of sliding the hanging portion 5 of the latch 3 from the insertion portion 6a toward the receiving portion 6b by the combined synergistic action with the outer wall material 1 and the mounting side 2 In the state where the play in the direction gradually decreases and the hanging portion 5 is received by the receiving portion 6b, the outer wall material 1 is played outwardly on the styrene board 2c on the mounting side 2 as described above. Not closely, rattle No attachment state is adapted to be formed.

  As shown in FIGS. 2A and 2B, the bottomed recess 6 having the above-described shape is coaxial with a conical portion 15b whose diameter increases toward the tip side on the tip side of the columnar portion 15a. The same router bit 15 as described in the background art is prepared, and the bit 15 is moved to a predetermined depth position in the meat of the outer wall surface material 1 at point A as shown in FIG. It was formed by grinding and advancing, and then moving sequentially from point B, point C and point D while maintaining the depth position, returning to point A, and separating from the outer wall surface material 1 Therefore, the bottomed recess 6 as described above can be easily formed by such a processing method.

  The attachment of the outer wall surface material 1 to the attachment side 2 may be performed at a factory or may be performed at a construction site, for example, as follows. That is, as shown in FIGS. 3 (A) and 3 (B) and FIGS. 4 (A) and 4 (B), the hanging portions 5 of the latches 3 on the mounting side 2 are respectively connected to the bottomed recesses 6 on the outer wall surface material 1 side. Are inserted into the insertion portion 6a.
