JP3124617U - Space partial partition form for molding multi-spaced concrete blocks - Google Patents

Abstract

Several multi-space concrete blocks have been devised for vegetation recovery by providing a vegetation space inside a concrete block and covering it with soil. The mold was composed of a lower mold having a large number of independent large and small recesses arranged vertically and laterally, and an upper mold having a reinforcing bar arranged thereon and overlapping with the lower mold. Since this formwork has a high formwork production cost, a short product cycle has caused a great risk to manufacture a new formwork. The present invention seeks to solve this drawback.
According to the present invention, a multi-spaced concrete block is formed by inserting a plurality of space partial partitioning molds to be a space part into an existing mold having an outer frame, and placing and removing the concrete after placing the concrete. It is to be molded.

Description

The present invention relates to a formwork for molding a multi-space concrete block provided with a vegetation space laid on a river revetment and road slope.

Several multi-spaced concrete blocks have been devised for the purpose of restoring vegetation by providing a space inside the concrete block, covering it with soil. (Patent Document 1) The mold is composed of a lower mold frame in which a large number of independent recesses of various sizes are provided at intervals in the vertical and horizontal directions, and an upper mold frame in which reinforcing bars are arranged and overlapped with the lower mold frame. It had been.
Patent No. 2513546

    Forms made up of independent large and small recesses that overlap in many directions vertically and horizontally have a high manufacturing cost, so the product cycle is short. It was accompanied. The present invention seeks to solve this drawback.

    The present invention is not a newly manufactured mold that forms a space part by superposing upper and lower molds provided with a large number of independent large and small recesses vertically and horizontally, but a plurality of partial partitions that become space parts The mold is inserted into an existing mold having an outer frame, and after placing the concrete, the space is molded by detaching.

    In the current situation where the block product cycle is short and a new formwork has to be created each time, a plurality of partial partition formwork to be a space part is inserted into and removed from an existing formwork having an outer frame. A multi-spaced concrete block can be molded.

Various multi-space concrete blocks can be freely designed by changing the shape, size, and number of the partial partition formwork that becomes the space.

  As shown in FIG. 1, four space partial partition molds 1 having a taper 2 that narrows downward and the height of the outer frame 6 or about several cm higher are inserted into the existing mold 5. The rebar 7 is arranged. FIG. 2 shows a state in which concrete 8 is placed and being cured, and thereafter, as shown in FIG. 3, the space portion 9 is formed by detaching the four space portion partition molds 1 from the existing mold 5. . FIG. 4 shows a multi-space concrete block 10 formed by four space partial partition molds 1.

FIG. 5 has a taper 2 that narrows downward, and is provided with a notch 4 for arranging a reinforcing bar 7. This is another embodiment.

Depending on the size of the space part of the multi-space concrete block, the design of the space part, and the arrangement of the reinforcing bars, the shape, size, number, and presence / absence of the notch of the space part partition form can be freely combined. The space partial partition form is a cast product made of iron, copper, aluminum, lead or the like, or a steel plate formed by welding or the like, and has a handle 3 for insertion / removal. Existing formwork can reuse formwork used for river revetments and road slopes. The present invention has a structure as described above. In the embodiment using the present invention, as shown in FIG. 7, a space is provided inside the concrete block to cover the soil and used for river revetment and road slope for the purpose of vegetation restoration. .
