Description

  The present invention relates to a breathable concrete design block whose design can be freely changed.

  Some concrete blocks that have both air permeability and design on the wall and wall are called design blocks and flower blocks.

  Unlike ordinary concrete blocks with cavities, these blocks are designed with emphasis on design and open a cavity that penetrates the rectangular block, and the space is designed by the cavities (called design blocks). It is a concrete block such as a flower block that has a pattern reminiscent of a flower.

  When building a block wall or a block wall using these design blocks or flower blocks, the air permeability is secured by the cavity, and the highly designed wall or wall is made by the beautiful pattern formed by the cavity that becomes the vent hole. Can be formed. Recently, it is often used as a partial accent design by embedding it in the outer wall or veranda wall.

Conventionally, these design blocks and flower blocks have been developed in various shapes, and the same shape can be stacked to form a pattern, or various shapes and blocks can be combined to create various characters, symbols, or Some of them are designed to form figures. In addition, in the industrial standard JIS A 5406, it is standardized as one form of building concrete block (one kind of hollow concrete block).

  The problem to be solved is a design block or a flower block that can be used in a wide variety of ways. Once a wall or fence is built using these various blocks, the wall or It is a point that must be broken and remade.

  In the present invention, in these design blocks and flower blocks, the frame block portion, which is the frame portion, and the hollow design portion formed inside the frame block, which is the design portion, are separated from each other, and the internal cavity design portion is attached and detached. It can be used interchangeably and the design can be changed freely.

  In addition, the frame block is made circular, elliptical, or polygonal to further increase the degree of design freedom. Further, a guide means for mounting the space design member on the frame block is provided so as to be detachable, and the guide means is easily mounted by a guide groove.

  The concrete block of the present invention has a structure in which the cavity design portion can be freely attached and detached, so that it is possible to change the design without changing the wall or the wall while ensuring air permeability and daylighting. There is an advantage that it can be changed to a block wall or a block wall.

  In addition, the frame block part and the cavity design part can be manufactured separately, which makes it easier to manufacture, allows for complex space design, and allows you to freely combine different materials, greatly increasing design freedom. Can be spread.

  A concrete frame block and a hollow design member inside it are manufactured separately, and are used by fitting them together, and the space design member is attached and detached by providing guide means for attaching the space design member to the frame block Realized.

  FIG. 1 is a perspective view showing an embodiment of a concrete block frame block according to the present invention. Various hollow design members 3 as shown in FIG. A guide groove 2 for fitting the end 4 is provided.

  Since the frame block 1 is stacked to form a wall or ridge, a rectangular shape or the like is preferable, but a polygonal shape, a circular shape, or an irregular shape may be used. In any case, any frame block may be used as long as it is a concrete frame member for fitting the space design member 3 to a wall or a wall.

  The guide groove 2 is a groove that serves as a guide when the end portion 4 of the hollow design member 3 to be fitted therein is fitted. This groove is formed halfway and stops at a predetermined position. And fixed at that position. The cavity design member 3 is locked with a fixing screw 5 as shown in FIG.

  In this embodiment, the guide groove 2 has four positions, top, bottom, left and right. However, the guide groove 2 may be provided according to the shape of the end portion 4 of the cavity design member 3 at an appropriate time, and the portion and the number of grooves may be arbitrary. It may be provided in the part.

  Further, the guide groove 2 may be provided so as to penetrate to the opposite surface of the frame block 1, and the fixing means may be means other than the fixing screw 5 such as a wedge, a pin, or simple adhesion. For example, the groove may be one step deeper at the fixing position, and the groove may be fixed by dropping into the deepened groove. Further, a stop plate may be embedded in or bonded to the frame block 1 so as to stop at a fixed position.

  FIG. 2 shows an embodiment of the cavity design member 3 for attaching to and detaching from the frame block 1. This is an example of the hollow design member 3 such as a circle with a cross, a rhombus with a cross, a lattice, or a radial shape.

  The hollow design member 3 may have any shape as long as an end 4 that fits into the guide groove 2 of the frame block 1 is formed. The shape of the end 4 may be other than a square shape, and the guide groove 2 is circular. It may be a groove or a pointed groove. Further, the frame block 1 may have a shape other than a square, and may be a circle or a polygon.

  FIG. 3 is a view showing an embodiment in a state in which a cross-shaped hollow design member 3 is fitted into the frame block 1, (1) is an overall perspective view, and (2) is an A in (1). FIG.

  The present embodiment is a concrete block in which a cross-shaped hollow design member 3 is fitted into a rectangular frame block 1, and guide grooves 2 are provided on the upper, lower, left and right sides of the frame block 1. Since the guide groove 2 is halfway, the hollow design member 3 is fixed with the fixing screw 5 as shown in the enlarged view of (2) so that the hollow design member 3 stops at the center of the frame block 1 and does not fall off. Can be done. Instead of the screw, a pin or a wedge may be used, or a temporary adhesive may be used. Any one can be used as long as it can be easily released when the space design member 3 is replaced.

  As described above, since the space design member 3 can be easily replaced, there is no need to recreate the entire concrete block when changing to various designs, which is economical and does not need to be made integrally with the frame block. So fine design is also possible.

  The hollow design member may not be made of concrete, and may be made of glass, metal, resin, wood or the like. In any case, it is possible to realize various designs by making it detachable, and it can be applied to various buildings such as objects, bridges, road surfaces, and towers.

  Moreover, when a translucent member is fitted into the hollow portion or a color film is attached to one side, it can be applied to a lighting design.

It is a figure which shows the Example of the frame block of the concrete block by this invention. It is a figure which shows the Example of the cavity design member by this invention. It is a figure which shows the vertical cross section of the concrete block by this invention.
