Description

  The present invention relates to a block that forms a wall surface of a house or the like by laminating a plurality, and particularly relates to a wooden block.

Buildings made of laminated wood to form wall surfaces have been widely used as schoolhouses and log houses since ancient times. In particular, in recent years, the demand for log houses has been on the rise due to outdoor orientation. The advantage of such a log house is not only in its appearance and interior appearance due to natural grain, but also in the new building materials, which can keep the room at a moderate humidity by breathing the wood forming the wall. You can't miss anything.
Original log houses using logs are practically difficult for individuals to construct in terms of procuring uniform timber, processing and designing timber, and rely on construction by specialized contractors. I must.

  Therefore, even if the present applicant is not a specialized contractor, Japanese Patent Application Laid-Open No. 2-17711 and Japanese Patent Publication No. 6-50007 are relatively easy to construct a log house without using special techniques and equipment. “Wooden block” is shown in the gazette, and “block for a wall surface of a house or the like” is shown in WO00 / 43606 international publication. This is not a method of laminating long wood, but by laminating short block-shaped woods while connecting them to form a wall surface similar to that of laminating long square members. That is, by connecting the horizontal direction at the locking portions at both ends of the block, connecting the top and bottom by the unevenness of the upper and lower surfaces, and forming the inclined surface on the convex portion of the upper surface, so as to drain rainwater that has permeated from the connection portion It is a thing. In Japanese Patent Publication No. 6-50007, the inclined surface is alternately formed on one side and the other side with the boundary near the center of the block, and the blocks can be laminated without considering the orientation of the front and back sides. The reversible type is provided so that rainwater entering from the connecting surface of the locking portion is drained to the outside. Therefore, according to these, it is possible to easily form a wall that is resistant to wind and rain by a simple manual operation such as stacking a sash on the bolt erected on the foundation.

    The present invention also forms a wall surface by laminating block-shaped building materials in the same manner as the applicant has shown above. However, in the present invention, in rainwater invasion countermeasures, particularly rainwater caused by capillary action is used. It is an object of the present invention to provide a block for a wall surface of a house or the like that can form a wall surface having a structure with further improved measures against intrusion.

  Therefore, in the present invention, a block that forms a wall surface of a house or the like by laminating a plurality, a hook-like engagement portion provided at both ends thereof, and a fitting convex portion provided on the upper surface and having a step. A fitting recess provided on the bottom surface to which the fitting projection of another block is fitted, and at least one slope formed on the top surface of the fitting projection to be inclined from one side to the other side. A first feature is that a drainage groove is formed in the block made of a surface.

  Moreover, the block for wall surfaces, such as a house of Claim 1, WHEREIN: It is the 2nd characteristic that the side wall surface of the said inclined surface was formed in the curved surface shape.

  According to the wall block of the house or the like according to the present invention, in the rain water intrusion countermeasure, it is possible to more effectively prevent rainwater permeated from the connecting portion of the block from being transmitted to the inner wall surface side in the structure. Have.

  Hereinafter, the best mode for carrying out the present invention will be described based on an embodiment shown in the drawings. 1 is a perspective view of the block according to the present embodiment as viewed obliquely from above, FIG. 2 is a plan view of FIG. 1, FIG. 3 is a bottom view of FIG. 1, and FIG. 5 is a right side view, FIG. 5 is a right side view showing a state in which the blocks of the present embodiment are stacked in the vertical direction, and FIG. 6 is a perspective view showing a state in which the blocks of the present embodiment are stacked in the vertical direction. It is.

  As shown in FIGS. 1 to 5, the block 1 of this embodiment includes a hook-like engagement portion 2 provided at both ends thereof, and a fitting protrusion formed with a step in a convex shape in both end directions of the upper surface. 3, a fitting recess 4 that is provided on the bottom surface and engages with a fitting projection 3 of another block 1 positioned below, and a pair of insertion holes 5 for positioning when the plurality of blocks 1 are stacked. It consists of. Thereby, it can connect easily in a vertical direction and a horizontal direction in a desired position.

  When the front side of the block 1 shown in FIG. 1 is defined as the outer wall surface side of a house or the like, and the back side of the block 1 is defined as the inner wall surface side, the engaging portion 2 formed at the left end of the block 1 It comprises a vertical groove-like engagement recess 21 that is recessed toward the wall surface, and an engagement protrusion 22 that is formed to protrude from the inner wall surface to the outer wall surface in the direction of the left end. The right end engaging portion 2 is formed in a direction opposite to the left end engaging portion 2. Since it is formed in this way, the engagement projection 2 engages with the engagement recess 21 of the other adjacent block 1, whereby the engagement portion 2 is connected in the lateral direction. Further, at the outermost corners of the engaging convex portions 22 at both ends of the block 1, the corners are cut in the vertical direction to form engaging convex groove 40. Further, at the corners on both ends of the upper surface of the fitting convex portion 3, the upper surface grooves 41 are formed by cutting the corners in the upper surface longitudinal direction. In addition, bottom grooves 42 that are concave in cross section are formed in the longitudinal direction of the fitting recess 4 at the corners on both sides of the fitting recess 4 formed on the bottom surface of the block 1.

  Since the block 1 is laminated, the engaging convex groove 40, the top groove 41, and the bottom groove 42 form a water drainage gap 48 between adjacent blocks. In addition, it is possible to prevent the rainwater from entering the block inner wall side by capillary action. Moreover, since a space | gap part is formed in the laminated | stacked block wall surface, ventilation property also improves.

  Further, on the upper surface of the fitting convex portion 3, a first inclined surface 31 that is inclined obliquely downward from the inner wall surface (one side) to the outer wall side (the other side) is provided on the right side of the approximate center. On the left side, there are formed second inclined surfaces 32 that are inclined upwardly from the outer wall surface side (other side) to the inner wall surface side (one side). Flat surfaces 33 and 34 higher than the inclined surfaces are formed, and a central flat surface 35 higher than the inclined surfaces is formed as a boundary portion between the first inclined surface 31 and the second inclined surface 32. . Further, the left and right side wall surfaces 31a and 31b of the first inclined surface 31 are respectively formed in a curved shape, and similarly, the left and right side wall surfaces 32a and 32b of the second inclined surface 32 are respectively formed in a curved shape. Yes. By forming it in a curved surface shape, it becomes easier for intruded rainwater or the like to flow from the upper side to the lower side of the inclined surface, and the drainage can be improved.

  Further, a wall projection 43 is provided in the opposite direction on the right end and the inner wall side left end of the block 1 on the outer wall side, and on the left end and the inner wall side right end of the block 1 on the opposite side. A wall surface recess 44 is provided in the direction, and is formed such that when the blocks are stacked, the wall surface protrusion 43 and the wall surface recess 44 of the adjacent block are engaged. When connecting the blocks 1 in the horizontal direction, the wall surface protrusions 43 and the wall surface recesses 44 of the adjacent blocks 1 are combined so that the adjacent blocks are aligned in the front-rear direction.

  The engaging portion 2, the first inclined surface 31, and the second inclined surface 32 are formed in completely opposite directions across the central flat surface 35, and one side surface and the other side surface, that is, the outer wall side and the inner wall side, As shown in each figure, it is a reversible shape. Therefore, when the blocks 1 are stacked, the engaging portions 2 may be simply connected without considering the front and back.

  Next, the operation of this embodiment will be described. Here, in order to identify a plurality of blocks, symbols 1a to 1f are attached to the blocks. As shown in FIG. 6, in order to form a wall surface by stacking a plurality of blocks 1a to 1f, vertical bars such as bolts 6 are vertically set in advance from a base surface (not shown) or a base (not shown). It is arranged so that it is easily placed at a desired position by being stacked while being inserted through the respective insertion holes 5. As described above, the connection in the horizontal direction is performed by simply engaging the engaging portions 2 of the adjacent blocks. In addition, the near side of the stacked blocks is defined as the outer wall surface side of a house or the like, and the back side is defined as the inner wall surface side.

  The engaging portion 2 of the block to be stacked is positioned by the bolt 6 so as to be positioned at the approximate center of the other blocks positioned below it. That is, by inserting the bolt 6 into the insertion hole 5 of each block, the boundary surface 21c between the engagement concave portion 21 and the engagement convex portion 22 of the engagement portion 2 on the left end side of the block 1c is just below It is located at the approximate center of the central flat surface 35 of the block 1b. On the other hand, the side surface 21a on the center side of the engaging recess 21 is within the range of the first inclined surface 31 located therebelow. In consideration of the gap between the bolt 6 and the insertion hole 5, that is, some play, it is desirable that the width of the central flat surface 35 be formed larger than this gap.

  Next, drainage when rainwater enters will be described. When building a wall such as a house by laminating blocks, rainwater or the like infiltrates into the wall from the top, bottom, left or right connecting parts of adjacent blocks. The joint portion 3 is provided, the engaging portion 2 that performs the lateral connection is bent in a bowl shape, or the first inclined surface 31 has an upward slope from the outside to the inside. Therefore, most of the rainwater can be prevented from entering. However, rainwater may enter the inside of the wall surface by a capillary phenomenon from a very narrow gap of the connecting portion. However, in the present invention, when the protruding convex groove 40, the upper surface groove 41, and the bottom surface groove 42 for draining are formed in the vertical direction and the longitudinal direction of the block, and these blocks are laminated, Grooves (40, 41, 42) form gaps between adjacent blocks, and capillary action is shut out here. Moreover, the drainage of the side wall surface of an inclined surface can be improved by forming the side wall surface of the 1st inclined surface 31 and the 2nd inclined surface 32 in the curved surface shape.

  As described above, the object of the present invention is to form grooves at a suitable position on the block so as to shut out rainwater and the like from entering the inside by capillarity from the connecting portion of the block, and when the blocks are laminated, It is to prevent intrusion of rainwater or the like by the gap formed by the groove. Accordingly, the bottom groove 42 may be formed in the longitudinal direction substantially at the center of the fitting recess 4. Further, the engaging convex groove 40 may be formed at a place other than the corner of the engaging convex portion 22. At this time, in this embodiment, it is necessary to form the block at a symmetrical position of the block 1 in order to make the block invertible.

  As described above, the block 1 of the present embodiment is formed so as to be reversible in its shape, and even if the second inclined surface 32 is disposed so as to be inclined toward the outer wall side, the same rainwater intrusion preventing effect can be obtained. It is done. Even in the case of the front and back irreversible blocks in which the second inclined surface 32 is not provided in the embodiment, the direction of the blocks is limited when stacking (that is, the first inclined surface 31 must always face the outside of the wall surface). The effect of preventing rainwater and the like from entering is exactly the same as in the above embodiment.

  The block of the present invention is not particularly limited in its material, and can be formed of any material such as resin, metal or ceramic, not to mention wooden. For example, resin can be applied to educational toys and the like, and combustion resistant ceramic and concrete can be applied to form an incinerator. In particular, since the blocks of the present invention are joined by engaging the blocks and inserting them into a vertical bar, a wall surface can be formed without using any joining agent, and the application range is wide.

  As described above, the block according to the present invention can form a wall surface by stacking, and a log house or the like can be easily constructed especially in the case of wood.
