Description

[Detailed Description of the Invention] This invention relates to a construction block used for forming a frame wall of a flower bed or the like.

This idea allows you to easily build a frame wall of the required size by stacking them, and by fitting the protrusions and recesses in the overlapped parts and allowing the use of fixing metal fittings, the frame wall has excellent strength. The purpose is to provide a block that can be easily used in place of conventional bricks.

Hereinafter, embodiments of this invention will be described based on the accompanying drawings.

As shown in the figure, the block body 1 is formed into a horizontally long prismatic shape, and has a plurality of protrusions 2 on its upper surface and a plurality of recesses 3 on its lower surface, each formed at a constant pitch in the longitudinal direction.

In the case shown in the figure, the protrusions 2 are formed into a low truncated pyramid shape and are arranged in four pieces, and the recesses 3 on the lower surface are formed in a shape and number that exactly fits each protrusion 2 when the block bodies 1 are stacked. However, the number of protrusions 2 and recesses 3 may be freely determined, and the shape may be a truncated cone or the like.

Decorative thin protrusions 4 and 5 are provided on the front surface and one end surface of the block body 1, and a decorative recess 6 into which the protrusion 5 fits when the block main bodies 1 are arranged is provided on the other end surface. ing.

On the back side of the block main body 1, near both ends, there are shallow recesses 7 into which the protrusions 5 fit when the block main bodies 1 are arranged at right angles.
is provided.

A fitting groove 10 for the fixing fitting 8 or 9 is formed on the outer surface of the central portion of the block body 1 so as to extend from the back surface to the upper and lower surfaces.

- As shown in FIG. 1, this fitting groove 10 includes a semicircular arc portion provided at the center on the upper and lower surfaces of the block body 1, and a semicircular arc portion continuous from both ends of the semicircular arc portion on the back surface of the block body 1. It is formed by two straight grooves 12.13 that reach up to A portion surrounded by the arcuate portion and the straight groove 12.13 becomes a locking portion of a fixing fitting 8.9, which will be described later.

The fixing fittings 8 and 9 are a rod 15 that connects the fitting 8 for fixing the block body 1 to the ground and the block body at the corresponding position.
Metal fittings 9 are prepared which are connected to each other to prevent them from falling.

The metal fitting 8 fixed to the ground is formed by bending a metal wire so as to fit into a groove 13 on the lower surface, and providing a driving part 17 for a nail 16 at the end of the metal wire.

The connecting fitting 9 is made of metal wire, and has a parallel part that fits into the vertical groove 14, and has parts shaped to fit into the grooves 12 and 13 on the upper and lower surfaces in series at both ends, and a connecting rod 15 in the center of the parallel part. It is formed by attaching the connecting part 18 of.

In the illustrated case, the block body 1 has a hollow interior made of synthetic resin, and an opening 19 provided on one end face can be opened and closed with a separate cap 20 to prevent soil and water from entering the inside during use. Although it is filled to give it weight, it is also possible to use concrete or chamotte to make it denser inside.

In addition, when the block bodies 1 are formed using synthetic resin, the adhesive strength may not be sufficient to bond the block bodies 1 to each other, so as shown in FIG. The iron plate may be embedded so that the surface is exposed so that the adhesive force of the adhesive is improved by the iron plate.

Furthermore, the groove 10 may be formed only on the upper and lower surfaces, omitting the rear surface.

This invention has the structure as described above, and its usage will be explained next.

Arrange the block bodies 1 in a frame shape on leveled ground or foundations, fit the protrusion 5 at the end into the recess 6 or 7 at the abutting part, and insert the fixing metal fitting into the groove 13 on the lower surface of the fitting groove 10. 8 is fitted, and a nail 16 is driven into the ground from the driving part 17 of this fixing metal fitting 8 to create a private room.

The block body of the second stage is placed on top of the first stage that has been framed in this way, and the recessed part 3 on the lower surface fits into the protrusion 2,
Layer them so that the positions of the end abutting parts are different.

Apply adhesive to the overlapping surfaces of the block bodies to fix them.

Continue stacking the block body 1 according to the steps above,
Build a frame wall of the required height.

A fixing metal fitting 9 is elastically fitted into the groove 10 of a suitable upper block body 1, and the corresponding fixing metal fittings 9 on both sides are connected with a connecting rod 15 using a turnbuckle or wire rod to prevent the occurrence of collapse. To prevent.

The frame wall thus completed is filled with earth and sand to form a flower bed.

As described above, according to this invention, the stacked block bodies are fixed by fitting the protrusion and the recess, so that a strong stacked state can be obtained.

In addition, the upper and lower surfaces of the block body are made up of a semi-circular arc-shaped part provided in the center and two straight parts that extend from both ends of this semi-circular arc-shaped part and reach the back of the block body, and lock the fixing metal fittings. Since we have formed a fitting groove to allow the bottom block to be fixed to the ground and the blocks in the corresponding position at the top to be connected, we can create a frame wall that is stable and does not collapse. can do.
