Description

  The present invention relates to an outer wall structure of a building, and more particularly to an outer wall structure that can maintain good appearance quality for a long period of time.

  Conventionally, as shown in FIG. 5, the outer wall board joint processing material 2 is stuck as an outer wall structure of a building so that it may straddle between the opposing edge portions 1a, 1a of the adjacent outer wall boards 1, 1. (For example, see Patent Document 1).

  In such a thing, the said outer wall board joint processing material 2 exhibits the strip | belt shape of the fixed width direction dimension W (W = about 5-20 cm), and the adhesive surface 4a is exposed by peeling the double-sided release paper not shown in figure. It has a pair of pressure-sensitive adhesive layers 4, 4 to be formed, an adhesive-layer migration preventing layer 5 provided as necessary, a nonwoven fabric 6, a reinforcing coating 7, and the like, and is mainly configured.

  In addition, an acrylic rubber-based elastic putty material 8 is applied from above the outer wall board joint treatment material 2 to the surface side between both end edges 1a and 1a where the outer wall board joint treatment material 2 is pasted. Thus, the steps formed on both side edges of the outer wall board joint treatment material 2 are configured to be smooth.

  And the finish coating layer 9 is apply | coated from on these elastic putty materials 8, and a process is substantially completed.

  In the conventional outer wall structure configured as described above, a certain gap is provided between the adhesive layers 4 and 4.

Therefore, even if the edge portions 1a and 1a of the outer wall boards 1 and 1 are relatively displaced due to an earthquake or the like, the outer wall board seam treatment material 2 expands and contracts to sufficiently follow the variation in the seam interval. can do.
JP 07-119273 A (paragraphs 0011 to 0022, FIG. 2)

  However, in such a conventional outer wall structure, the adhesive surfaces 4a and 4a must be attached along the surface sides of the edge portions 1a and 1a, respectively. During construction, the number of processes will increase.

  Also, an acrylic rubber-based elastic putty material 8 is applied on the outer wall board joint treatment material 2 so that the steps formed on both side edges of the outer wall board joint treatment material 2 are smoothed. ing.

  For this reason, there is a problem that the skill of the installer is easily reflected in the quality of the finish of the finish coating layer 9 applied to the outermost surface, and it is difficult to always obtain a certain appearance quality.

  Further, the outer wall board joint treatment material 2 has a problem that it deteriorates in appearance quality of the finish coating layer 9 applied to the outermost surface due to aging or expansion due to deterioration over time.

  Then, this invention makes it a subject to provide the outer-wall structure which can be constructed easily and can maintain favorable external appearance quality over a long period of time.

  In order to achieve the above object, the invention described in claim 1 is characterized in that the outer wall portion is slidably movable in the surface extending direction at a predetermined distance from the outer wall structure and the outer surface of the outer wall structure. The outer wall finishing material to be mounted, the outer wall finishing material interposed between the outer wall finishing material and the outer wall structure, and the outer wall finishing materials arranged adjacent to each other are fixed to each other, and the outer wall finishing material is attached to the outer wall finishing material. On the other hand, an outer wall structure having a trunk edge to which an adhesive material is used is attached.

  Further, according to a second aspect of the present invention, there is provided a finishing material mounting surface portion that is interposed between the outer wall finishing material and the outer wall structure and fixes the outer wall finishing material, and an outer surface of the outer wall structure. The outer wall structure according to claim 1, wherein the slide locking member protruding from the side has a slide jig member having a structure-side mounting surface that forms an elongated hole to be inserted.

  Further, according to the third aspect of the present invention, the edge of the outer wall finishing material disposed adjacent to the body edge interposed between the outer wall finishing material and the outer wall structure is fixed to each other. In addition, the outer wall structure according to claim 1 or 2, wherein a finishing layer covering the outer surface of the outer wall finishing material is provided across the edges of the outer wall finishing material.

  According to the first aspect of the present invention configured as described above, the outer wall finishing material provided on the outer wall portion is mounted at a certain distance from the outer surface of the outer wall structure.

  For this reason, the construction performed on the outer surface of the outer wall structure is covered with the outer wall finishing material and cannot be visually recognized from the outside, and good appearance quality can be maintained over a long period of time.

  The outer wall finishing material is attached to the outer wall structure so as to be slidable in the surface extending direction.

  For this reason, even if a deformation such as a distortion occurs in the outer wall structure of a building due to an earthquake or the like, the displacement between the outer wall finishing material and the outer wall structure slides in the surface extending direction and the displacement is absorbed. The

  Accordingly, the surface of the outer wall finishing material is hardly affected by the deformation of the outer wall structure of the building, and a certain appearance quality can be maintained even after the occurrence of an earthquake.

  Further, the outer wall finishing materials arranged adjacent to each other are fixed to the trunk edge. For example, the surfaces of the outer wall finishing materials can be made flush with each other on the outer surface of the trunk edge by abutting the end faces.

  And since the dimensional distance between the outer wall finishing materials fixed to the trunk edge is always kept constant, the gap dimension between the both end edges does not change, and the appearance quality is always good. can do.

  Further, in the present invention, the outer wall finishing material is fixed to the finishing material mounting surface provided on the slide jig member.

  Further, a slide locking member projecting from the outer surface of the outer wall structure is inserted into a long hole formed in the structure side mounting surface of the slide jig member.

  Since the slide locking member is slidable along the longitudinal direction of the long hole, even if the outer wall structure of the building is deformed, the outer wall finishing material is hardly affected.

  And since the slide jig member provided between the two body edges is supported by the slide locking member inserted through the elongated hole, each body edge can be attached to the outer wall structure. It can be done with a simple adhesive.

  Further, according to the third aspect of the present invention, the edges of the outer wall finishing material arranged adjacent to each other across the finishing layer are abutted against the trunk edge and fixed.

  For this reason, the gap dimension between both end edges does not change, and there is no possibility of generating cracks or distortion due to displacement in the finished layer.

  Therefore, it is possible to provide an outer wall structure that can be easily constructed and can maintain good appearance quality over a long period of time.

  Next, an outer wall structure according to the best mode for carrying out the present invention will be described with reference to the drawings.

  1 to 4 show an outer wall structure according to an embodiment of the present invention.

  First, in terms of the configuration, in this embodiment, as shown in FIG. 1, a plurality of the inner wall portions are configured by abutting the opposite end edges 1a, 1a of the outer wall boards 1, 1 arranged adjacent to each other. The outer wall structure 10 having a predetermined internal hollow space by being fixed to the both side end surfaces of the frame members 12 and 12 extending in the vertical direction at regular intervals together with the gypsum board 11. Is formed.

  On the outer surface of the outer wall structure 10, outer wall finishing materials 13, 13 extend along the vertical direction so as to straddle between the both edge portions 1 a, 1 a, and these rims 14, 14. A plurality of drill screw members are interposed between the body edges 14 and 14 and a slide jig member 15 which is attached to the frame member 12 while allowing a certain amount of sliding movement in the horizontal direction to be allowed. 16 or the log screw member 21 is used and mounted.

  Among these, the body edge 14 is bonded using a double-sided adhesive tape 17 having a predetermined thickness so as to straddle between the opposite end edges 1a, 1a of the outer wall boards 1, 1.

  Adhesives 18, 18 are interposed on the outer side surface of the body edge 14 to temporarily fix both end edges 13 a, 13 a of the outer wall finishing materials 13, 13 and back of the plurality of drill screw members. These end edges 13a, 13a are fixed by 16.

  As shown in FIG. 2, the slide jig member 15 has a substantially M-shaped horizontal cross section, and a longitudinal direction in the horizontal direction on the structure-side mounting surface 15a having a central valley groove shape. Along each of the holes, three long holes 19 are formed.

  In these long holes 19, 19 are inserted round wood screw members 21, 21 as slide locking members with washer members 20, 20 interposed therebetween.

  These round wood screw members 21 and 21 pass through the outer wall board 1 and are screwed to the frame member 12, and in the screwed state, as shown in FIG. Fifteen side flange portion leading edges 15b, 15b are configured to be spaced apart from the outer surface of the outer wall board 1 with a fixed distance d.

  For this reason, the log screw members 21 and 21 are slidable along the horizontal direction in the long hole portions 19 and 19. Therefore, even when deformation such as distortion occurs in the outer wall structure 10 of the building, the displacement between the outer wall finishing material 13 and the outer wall structure 10 is slid in the surface extending direction so that the displacement is absorbed. It is configured.

  And the coating 22 as a finishing layer is given and provided so that the outer surface of these outer wall finishing materials 13 and 13 may be covered over the edge 13a, 13a of these outer wall finishing materials 13 and 13 It has been.

  Next, the effect of the outer wall structure of this embodiment will be described.

  In this embodiment, the outer wall finishing materials 13, 13 provided on the outer wall portion of the building are mounted at a certain distance from the outer surface of the outer wall board 1 constituting the outer surface of the outer wall structure 10. .

  For this reason, the construction and the like, which is performed on the outer surface of the outer wall structure 10 and provided with a gap between the edge portions 1a and 1a of the outer wall boards 1 and 1, are covered by the outer wall finishing materials 13 and 13. Cannot be seen from the outside.

  For this reason, the outer wall structure 10 does not need to consider appearance quality, and can provide a function of maintaining the strength of the building.

  Moreover, since it is not necessary to apply an acrylic rubber-based elastic putty material 8 on the outer wall board joint treatment material 2 as in the prior art, the construction is easy, and a good and constant appearance over a long period of time. Quality can be maintained.

  The outer wall finishing material 13 is attached to the outer wall structure 10 so as to be slidable in the surface extending direction via the slide jig member 15.

  For this reason, even if deformation such as distortion occurs in the outer wall structure 10 of the building due to an earthquake or the like, the space between the outer wall finishing materials 13 and 13 and the outer wall structure 10 is mainly in the surface extending direction. The displacement is absorbed by sliding relative to the horizontal direction.

  Therefore, the surface of the outer wall finishing material 13 is hardly affected by the deformation of the outer wall structure 10 of the building, and a certain appearance quality can be maintained.

  Moreover, as shown in FIG. 1, the edge 13a, 13a of the outer wall finishing materials 13 and 13 arrange | positioned adjacent to each said trunk edge 14 and 14 is each fixed.

  For example, as in this embodiment, the surface positions of the outer wall finishing materials 13, 13 can be easily formed on the outer surface of the trunk edge 14 by abutting and fixing the end edges 13 a, 13 a to each other. Can be made flush with each other.

  The dimensional distance between the outer wall finishing materials 14 and 14 fixed to the body edge 14 is always fixed by the fixing by the drill screw members 16 and 16, so that the gap between the end edges 13a and 13a is constant. Dimensions do not change.

  Accordingly, even if the straddle between the both end edges 13a and 13a is applied as the finishing layer, the gap dimension between the both end edges 13a and 13a does not change, so that a crack or distortion due to displacement is generated in the finishing layer. There is no fear, and the appearance quality can always be improved.

  Further, the outer wall finishing material 13 is fixed to the finishing material mounting surface portions 15 c and 15 c provided on the slide jig member 15 by drill screw members 16 and 16.

  In addition, a round wood screw member 21 protruding from the outer surface of the outer wall structure 10 is inserted into the long hole 19 formed in the structure-side mounting surface 15a of the slide jig member 15, The outer wall finishing material 14 is locked and supported so that it cannot be removed.

  Since this round wood screw member 21 is slidable along the longitudinal direction of the long hole 19, even if the outer wall structure 10 constituting the housing of the building is deformed, the outer wall finishing materials 14, 14 are formed. It is hard to be affected.

  In addition, in this embodiment, the front flanges 15b, 15b of the both side flange portions of the slide jig member 15 are spaced apart from the outer surface of the outer wall board 1 with a constant distance d. .

  For this reason, even if the outer wall finishing materials 14, 14 together with the slide jig member 15 are slid relative to the outer wall structure 10 in the horizontal direction, the outer surface of the outer wall board 1 and the slide jig The displacement can be absorbed while the member 15 moves smoothly without interference.

  Then, the slide jig member 15 provided between the body edges 14, 14 only screws the round wood screw member 21 inserted through the long hole 19 to the outer wall board 1 and the frame member 12. Thus, the outer wall finishing material 14 can be supported easily.

  For this reason, the load of the outer wall finishing material 14 is transmitted and supported from the slide jig member 15 to the frame member 12 of the outer wall structure 10 via the log wood screw member 21, and is located on both sides. The body edges 14, 14 can be attached to the outer wall structure 10 with simple double-sided adhesive tapes 17, 17, etc.

  Therefore, at the time of construction of the outer wall, the application and curing of the elastic putty material 8 and the finish paint as in the past can be simplified or eliminated, and the construction can be performed more easily.

  In addition, there is no possibility that the appearance quality of the finish coating layer 9 applied to the outermost surface is deteriorated due to the deterioration with the passage of time as in the conventional outer wall board joint treatment material 2 due to deterioration over time. And since the finishing layer can be formed on the surface of the outer wall finishing material 13, 13 where the gap dimension between the both end edges 13a, 13a does not change, a tape or putty material etc. that closes the gap between the both end edges 13a, 13a It becomes unnecessary.

  For this reason, the unevenness | corrugation of the surface does not generate | occur | produce like the past, and even if it carries out relative displacement of a building by an earthquake etc., the coating 22 surface is not affected.

  Therefore, it is possible to provide an outer wall structure that is easy to construct and can maintain good appearance quality over a long period of time.

Even if some of the drill screws 116 and 116 having relatively large lengths are used for a part, the outer wall finishing materials 13 and 13 are allowed to move in a horizontal direction with respect to the frame member 12 with a certain size. It is only necessary to be attached in a state where

  Moreover, in the said embodiment, although the double-sided adhesive tape is used as an adhesive material, it is not restricted to this in particular, For example, you may use an elastic adhesive material etc.
