Description

  The present invention relates to a method for constructing a decorative wall surface that forms a desired pattern on a wall surface using a molding material such as mortar and an embossing board.

  Conventionally, Patent Document 1 proposes a method for constructing a decorative floor surface in which natural stones, natural rocks, bricks, and tile-shaped patterns are formed on the floor, and are put to practical use. In this technology, a molding material mixed with adhesive, water, cement, and sand is applied to the floor surface, and the surface of the uncured molding material is pressed with a stamp body having an uneven pattern on the inner surface. A decorative surface having a texture close to that of a natural material can be easily applied in a short period of time by forming it at the same time and then curing it and performing a surface treatment such as coloring.

By the way, when pressing with a stamp body, considerable force is required. When this technology is applied to a wall surface, an operator can ride on the stamp body and apply a strong weight on the floor, but the wall surface presses in the horizontal direction, making it difficult to apply force and forming the surface pattern and joints simultaneously. It is difficult to do. Although it is possible to hit the stamp body with a hitting machine or the like, there is also a problem that the molding material coated vertically by the impact is easily peeled off from the base surface. Also, since the inside surrounded by the frame part that molds the joints of the stamp body when pressed is sealed, the inside becomes vacuum when the stamp body is pulled out after pressing, and the molding material adheres to the stamp body and peels off from the base surface There was also a problem.

  The problem to be solved by the present invention is to solve these conventional problems, to form a surface pattern and joints with little force without peeling, and to easily construct a wall surface having a texture close to that of a natural material It is to provide a construction method.

The configuration of the present invention that solves this problem is as follows.
1) A molding material that hardens in a predetermined time is applied to a concrete wall surface or a wall base surface, and a surface pattern is formed by pressing an uncured molding material surface with an embossed pattern having an uneven pattern on the inner surface. Form the joints so as to partition the surface pattern into a predetermined shape and size by pressing the surface of the uncured molding material deeply from the recesses of the surface pattern with the embossed frame composed of thin plates. A decorative wall surface construction method characterized in that it is formed stepwise in a separate process. 2) The embossed frame has one unit of joint pattern formed in a repeated pattern so that the joint is continuous with the same impressed frame. The decorative wall surface construction method as described in 1) above, wherein the joint is formed over a wide area by repeatedly pressing. 3) Coloring the surface of the molding material after applying the molding material and before pressing with the embossing machine Spread the powder for the surface, and then remove the surface pattern and joints. The decorative wall surface construction method described in 1) or 2) described above 4) A release agent having a color different from the color of the powder is applied to the surface of the powder for coloring to form a surface pattern and joints. Removing the release agent other than the joint part and leaving the release agent on the joint so that a joint with a color different from the color of the surface pattern appears. The decorative wall surface construction method according to any one of 1) to 4) above, wherein a sealer is applied to the surface pattern and joint surface to enhance durability.

  According to the present invention, the molding of the surface pattern can be pressed with a small force because the recess of the embossing plate is shallow and there is no frame. Does not peel off. In addition, since the joint is formed only by the frame and there is no portion received by the surface, it is possible to easily form a deep joint by pressing with a small force. In this way, the surface pattern and joints are molded step-by-step in a separate process using a dedicated embossing machine and embossing frame, respectively, so that it can be reliably molded without peeling with a small force compared to the simultaneous molding method become.

  For coloring the decorative wall surface, a coloring material may be mixed with the molding material, or coloring powder may be sprayed on the surface of the coated molding material, and then a surface pattern and joints may be formed. At the time of molding, a release agent (liquid or powder) is applied to facilitate the removal of the embossing board. At this time, if a release agent with a color different from the color of the coloring powder is used, the surface pattern In addition, the release agent other than the joint portion is formed by forming the joint, and the joint having a color different from the color of the surface pattern can be displayed three-dimensionally while leaving the release agent on the joint. A sealer is applied to the surface pattern and joints after molding so as to improve glossiness, stain resistance, weather resistance and the like. Embodiments of the present invention will be specifically described below with reference to the drawings.

  FIG. 1 is an explanatory view showing a joint pattern of the decorative wall surface of the embodiment, FIG. 2 is a perspective view of the uneven surface side of the embossing board of the embodiment, FIG. 3 is a perspective view of the handle side of the embossing board of the embodiment, FIG. 4 is a perspective view of the embossing frame of the embodiment, and FIGS. 5 and 6 are explanatory views showing the construction process of the embodiment. In the figure, 1 is a wall substrate, 2 is a molding material, 3 is a surface pattern, 4 is a joint, 5 is a powder for coloring, 6 is a sealer, 7 is a release agent, 8 is a wool roller, 10 is an embossing board, 10a is an uneven pattern, 10b is a handle, 11 is an embossed frame, 11a is a four frame, 11b is a partition frame, and 11c is a handle.

  The embossing machine 10 (seamless mat) used in the construction of this example is entirely made of urethane rubber (or urethane resin) as shown in FIG. 2, and has a stone-like uneven pattern 10a with no seam on the inner surface. The measured dimensions are about 70 × 70 cm. As shown in FIG. 3, the embossing frame 11 is composed of an elongated stainless steel plate as a whole, and a plurality of partition frames 11b are formed to form joints so that a plurality of tiles are abutted inside the four frames 11a.

  In the present embodiment, the unevenness of the surface of the wall base 1 to be decorated in advance is smoothed or cleaned to prevent the molding material 2 from peeling off. First, the molding material 2 made of mortar is coated on the surface of the wall base 1 with a trowel or the like so as to have a thickness of 10 to 20 mm as shown in FIG. Hardinner) is sprayed to a thickness of about 2 to 3 mm, and a release agent 7 (liquid releaser) darker than the coloring powder 5 is applied with a wool roller 8.

  Next, the coated molding material 2 is dried for 30 minutes to 1 hour to become hard enough to be embossed, and then the uncured molding material 2 is formed on the embossing board 10 as shown in FIG. The surface is pressed laterally to form a mold and this process is performed randomly across the surface to be decorated. At this time, the part to be embossed is only a pattern surface with a shallow recess, and the joints are not embossed, so air enters and exits when pressed and it can be easily molded with a relatively small force without being sealed and pulled out At that time, the pressure is easily released by the entry and exit of air, and the molding material 2 does not adhere to the embossing plate 10 and does not peel from the wall base 1.

  Next, as shown in FIG. 6 (a), the surface pattern 3 is pressed in the horizontal direction by the mold pressing frame 11, and the mold of the joint 4 deeper than the recess of the surface pattern 3 is attached. A number of joints 4 are repeatedly formed so as to form a pattern in which tiles are continuously abutted by sequentially performing this process. At this time, since the embossing is only the joint 4 portion, there is no portion to be received by the surface, and the deep joint 4 can be easily formed with a small force without requiring a striking force or the like.

  After forming, use a tool to correct the protruding part, etc., and dry it for several days to completely cure it. Then, the mold release agent 7 is washed with an apparatus such as a polisher so that the mold release agent 7 remains only in the recesses and joints 4 of the molded surface pattern 3, and the three-dimensional effect of the recesses and joints 4 of the surface pattern 3 is obtained. Make it appear.

  After that, it is dried, and a sealer 6 is applied to provide sealing, strength improvement, waterproofness, stain resistance, weather resistance, and gloss. The sealer 6 is performed by spraying or brushing. In this way, a high-quality decorative wall surface having an appearance that natural stones are spread is obtained.
