Description

  The present invention relates to a method for manufacturing a wall member and an outer wall using the wall member, and in particular, a method for manufacturing a wall member that can be used for a corner portion of a wall of a siding structure, and the use of the wall member. It relates to the outer wall.

  Conventionally, a known siding panel is used as an outer wall of a building such as a house. A siding panel is a plate-like member obtained by kneading a fiber material such as a cement material or glass fiber, filling it into a mold, molding it, and curing it. A corner member in which two panels cut out from a long siding panel are bonded in an L shape is used at the corner of the wall. However, the conventional L-shaped member has a problem that it is time-consuming to manufacture and expensive. In addition, there is a problem that it is necessary to handle it carefully because it is easily damaged during storage and transportation.

Therefore, the inventor has invented and filed an application for a wall member that can be used for a corner portion and that is easy to manufacture, transport, and store, and an outer wall that uses this wall member. Patent Literature 1 below discloses this wall member and an outer wall using the wall member. The wall member has a rectangular plate shape, and the two opposite side surfaces are also given the same design as the surface. When used for the exit angle portion, the wall member is cut and arranged alternately on one wall and the other wall of the exit angle so that the angles are aligned in the vertical direction. The wall member can be manufactured by the same manufacturing method as a conventional siding panel, and since it is flat, it is easy to transport and store and is not easily damaged. In addition, the outer wall has no joints at the corners, so it looks good and is easy to install.

Another feature is that the end face is cut so as to have an arc shape, and a groove corresponding to the joint groove formed on the surface of the siding panel is formed on the end face.

  Further, the above-described method for manufacturing a wall member is characterized in that a spacer made of the same material is bonded to the concave portion in the edge processing step. Further, the above-described method for manufacturing a wall member is characterized in that the vertical width when the spacer is applied is slightly narrower than the vertical width of the recess. Further, in the method for manufacturing a wall member described above, the wall member before forming the recess for mating is used in the edge processing step, and only the portion other than the vicinity of the end surface in the horizontal direction is cut by cutting. Another feature is that a recess for forming a hole is formed.

  The main feature of the outer wall of the present invention is that a plurality of wall members manufactured in the above-described method for manufacturing a wall member are arranged side by side on one wall of the exit angle so that ends processed in the vertical direction are aligned. To do.

The manufacturing method of the wall member of the present invention has the following effects due to the above-described features.

(2) The end surface is cut into a curved surface, etc., and joint grooves provided as designs on the panel surface are also formed on the end surface, and the same coating is applied, so that the details of the end surface are different from the design on the surface side. However, it seems that the end face is continuous with the surface, and even if it is applied to any existing wall member, there is almost no sense of incongruity.

(3) By the method for manufacturing a wall member of the present invention, an outer wall member for a projected corner in which one end or both ends of an arbitrary length including a long length is processed can be obtained. A seam is not generated at a natural position, and the outer wall member of the present invention is arranged side by side on one surface of the protruding corner, so that the appearance is improved.
(4) Construction is easier than when using L-shaped wall members for corners.

  Embodiments will be described below with reference to the drawings. In addition, in an Example, the example arrange | positioned in an outer wall so that the longitudinal direction of a long wall member may become horizontal is demonstrated, and the longitudinal direction of the wall member to which the process of this invention is given is demonstrated below. The side surface of the end portion is referred to as “end surface”, and the upper and lower side surfaces on which the recesses and protrusions are formed are referred to as “side surfaces”. Further, in the following embodiments, examples in which the processing of the present invention is performed on the right end surface of the wall member will be disclosed.

  1A and 1B are a plan view and an end view showing a configuration of an existing siding panel which is a base of a wall member of the present invention. Note that the end view on the left side of FIG. 1 shows the end surface of the wall member 10 as viewed from the direction A (the same applies hereinafter). The existing wall member (siding panel) 10 has, for example, tiles and joint grooves on the surface, and the interior of the joint grooves 11 is painted differently from the surface. The cut end surface is a flat surface, and a pegging recess 13 is provided on the lower side, and a pegging projection 12 is also provided on the upper side.

  FIG. 9 is a flowchart showing the method for manufacturing the wall member of the present invention. In addition, S10-S13 has shown the manufacturing process of the existing member for walls. In S10, a long plate-like wall member 10 is manufactured by kneading fiber materials such as cementitious materials and glass fibers, filling them into molds, molding them, and curing them. The completed wall member 10 has a flat back surface as a whole, and is not formed with a concavity recess 13 or the like.

  In S11, the surface of the wall member 10 is painted. For example, the process of applying the impregnated sealer to the entire surface, the process of applying the waterproof sealer to the entire surface, the enamel coating process of painting one color or a plurality of colors by lysine coating, the process of coating only the inside of the horizontal joint groove 11, A sputter coating step of spraying a paint containing particles such as fine sand may be included.

  In S12, the long plate-like wall member 10 is cut into a predetermined length. In S13, a machine tool such as a router is used to perform cutting of the concave portion 13 for laminating the lower side surface and chamfering of a corner on the back side of the convex portion on the upper side surface. The existing wall member 10 as shown in FIG. 1 is completed by the above process.

  2A and 2B are a plan view and an end view showing the configuration of the wall member in the edge processing step of the manufacturing method of the present invention. In the end portion processing step of S15 of FIG. 9, the end portion (near the end surface) of the convex portion on the upper side is cut out by a predetermined length to form a notch 23. The length to be cut may be, for example, about several times the thickness of the wall member 10. Further, when cutting off, a small amount (for example, about 1 to several millimeters) is left leaving a convex portion. This is for the purpose of leaving an effect of a slight overlap at the end when combined with the opposing wall member 10.

  FIG. 3 is a perspective view showing the structure of the spacer used in the edge processing step of the manufacturing method of the present invention. In S15 of FIG. 9, the spacer 20 is adhered to the end (near the end surface) of the recess on the lower surface with an adhesive. The spacer 20 is made of the same material as the wall member 10 and has a length that is, for example, about several times the thickness of the wall member 10.

  The cross section of the spacer 20 is substantially the same shape as the cross section of the counterboring recess 13, but the width (length in the vertical direction) is slightly smaller than the width of the counterboring recess 13 (for example, about 1 to several millimeters). ) Narrower (shorter). This is because the above-described concave portion for fitting the convex portion on the upper surface left at the end portion is formed. Therefore, as shown in FIG. 2, the bottom portion 21 of the bonded spacer 20 is slightly recessed from the bottom surface 22 of the wall member 10, and the vertical position is higher.

  In S16 of FIG. 9, the end surface processed is cut into a curved surface or a multi-surface shape. Moreover, the groove | channel corresponding to the joint groove | channel formed as a design in the surface of the member 10 for walls is also formed in an end surface.

  FIG. 4 is a plan view and an end view showing the configuration of the wall member in the cutting step of the manufacturing method of the present invention. In this embodiment, the end face is cut so that the horizontal cross section has an arc shape whose length is equal to or less than the thickness of the wall member 10, and grooves corresponding to the joint grooves formed on the surface of the siding panel are formed. It is formed on the end face.

  The cutting method is as shown in FIG. 4A while rotating a shaft 32 of a cutting blade provided with a cutting blade 30 for forming joint grooves and a cutting blade 31 for end face cutting as shown in the right end of FIG. The curved surface and the groove are simultaneously cut by moving the shaft in an arc shape. Alternatively, as shown in FIG. 4B, first, the curved cutting blade 37 is pressed against the end face while rotating, and moved in parallel with the end face to cut the end face into a curved surface. Next, while rotating the shaft provided only with the cutting edge 30 for forming the joint groove, the groove is cut by moving the shaft in an arc shape as shown in FIG.

  In S <b> 17 of FIG. 9, the cut portion 35 is painted so as to have the same design as the surface. Moreover, in S18, the inside of the groove | channel 36 of a cutting part is painted. The coating process is the same as the existing wall member process, for example, a process of applying an impregnated sealer to the entire cutting surface, a process of applying a waterproof sealer to the entire cutting surface, or one color on the cutting surface excluding the grooves by lysine coating or You may include the enamel coating process which coats several colors, the process of coating only the inside of the horizontal joint groove 11, and the sputter coating process of spraying the coating material containing particles, such as fine sand, on the whole cutting surface.

  FIG. 5 is a plan view and an end view showing the configuration of the wall member in the coating process of the manufacturing method of the present invention. When painting the cutting surface 35 excluding the groove, the groove portion is masked by the mask plate 41 and the paint is sprayed by the spray gun 40. The cutting surface 36 of the groove portion is brought close to the spray gun to spray the paint only in the groove.

  FIG. 6 is a plan view and an end view showing a configuration in which the wall members of the present invention are arranged in combination. FIG. 7 is a partially cutaway perspective view showing the wall structure of the corner portion using the wall member of the present invention. As a result of the inventor making a prototype of the wall member of the present invention and experimenting, it is good to place the wall member 10 vertically on one wall of the outgoing angle so that the ends processed in the vertical direction are aligned. And it turned out that construction was also easy.

  The wall member 10 is fixed using a metal fitting (not shown) fixed to the column 52. As shown in FIG. 6, the wall member 10 of the present invention combined vertically is maintained at the end portion even though it is slightly, and the waterproof property is improved. Further, the gap between the upper and lower wall members 10 cannot be seen from the surface, and the appearance is good. Further, an existing wall member 51 having a flat end surface is used as the other surface, and a sealing agent 50 is provided between the rear end surface of the wall member 10 of the present invention and the end surface of the existing wall member 51. Although filled, this seam is present only on one side, so providing a seam on the inconspicuous side further improves the appearance.

  FIG. 8 is a cross-sectional view showing the shape of another embodiment of the end of the wall member. In the embodiment shown in FIG. 4, an example is disclosed in which the horizontal cross section of the end portion is an arc shape whose radius is equal to the thickness of the wall member 10, but the end portion may have another shape. The example of FIG. 8A is an example in which the horizontal cross section of the end portion is an arc shape whose radius is half the thickness of the wall member 10, and the example of FIG. This is an example of a flat surface. The example of FIG. 8C is an example in which only a part of the end portion is an inclined plane, and the example of FIG. 8D is an example in which the end portion is configured by a plurality of stepped planes. The example of (e) is an example which comprised the edge part by two concave curved surfaces.

  In Example 1, it shifted from S13 of FIG. 9 to S15, and disclosed the method of manufacturing the wall member for an exit corner from the completed existing wall member. However, in Example 1, the concave portion on the side surface is provided by cutting, and then the end portion of the concave portion is filled with the spacer. Therefore, in Example 2, the wall member before the formation of the recess for mating, which is an intermediate product after the process of S12, is used, and only the side surface other than the vicinity of the end surface is used for mating in S14. By forming the concave portion by cutting, a wall member for a corner is manufactured. In this way, it is not necessary to bond the spacers to fill the recesses, the process is simplified, and the seam due to bonding is eliminated, and the appearance is improved.

  In the flowchart shown in FIG. 9, there are two coating processes, S11, S17, and 18. However, when manufacturing a wall member for a corner, the process of S11 is skipped, and the surface of S17 and 18 is the surface. Further, both the end face and the end face may be painted.
