Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial field of application) The present invention relates to a concrete block, and more particularly to a concrete block construction device having a portion protruding from a construction surface as seen in various boundary blocks.

(Prior art) For example, when constructing a road surface with a step by a block provided at the boundary between a roadway and a sidewalk, it is unclear which height of the conventional block should be covered with concrete, Alfalto, etc. Therefore, it is necessary to decide the position at the time of construction.

Therefore, it takes skill to perform conventional block construction,
The construction surface is difficult to be uniform.

(Problem to be Solved by the Invention) An object of the present invention is to provide a concrete block construction device that is easy to construct, can form a constant construction surface without requiring skill, and can shorten the construction period.

(Means for Solving the Problem) In order to achieve the above-mentioned object, the present invention has a portion 1 which is continuously laid in a certain direction and which projects upward from a construction surface P,
A block main body 2 in which at least one side face 3 is provided with a protrusion 4 indicating the position of the construction surface P corresponding to the inner lower side of the substantially C-shaped groove C on the at least one side surface 3, and the protrusion. Part 4
Is provided at a constant distance from the side surface 3 provided with the upper surface 10a, and the upper edge 10a indicates the position of the construction surface P corresponding to the outer lower side of the substantially L-shaped groove C, and the block below the protruding portion 4 Form 10 that forms a space for pouring concrete between itself and body 2, and in order to fasten form 10 to the block body 2, it is embedded in side surface 3 of block body 2 below protrusion 4. The construction means is configured by the anchor 7 and the separator 8 for fastening, which has a screw capable of being screwed with the screw 6 provided therein.

(Example) Explaining with reference to the drawings, FIG. 1 illustrates a curb block capable of forming an L-shaped groove C as shown in FIG. 4, and the block body 2 has a rectangular parallelepiped shape. However, most of them project from the construction surface P. A projecting portion 4 is provided on one of the side surfaces 3 on both sides in the longitudinal direction, and the projecting portion 4 illustrated has a uniform cross-sectional shape over the entire length of the main body, and its upper edge 4a has a height higher than that of the construction surface P. The position is shown. In the example shown in FIG. 3, similar projections 4 and 4'are provided at the same positions on both side surfaces 3 and 3 ', which are used for boundaries.

The block bodies 1 and 1 ′ can be embodied in various forms other than those shown as examples, and as for the type of FIG. 1, there are curved blocks at the corners, cut-down blocks provided at the entrances and exits of automobiles, etc. The above configuration can be applied as it is.

Further, anchors 7 having female threads 6 are embedded in the side surfaces 3 and 3'of the block body 2 as attachment means of the form holder 5 for forming a construction surface. The mold holder 5 has a long separator 8 as a member for fastening, which has a male screw threadedly engaged with the female thread 6 at the tip thereof, a screw rod 9 screwed therewith, and a home tie attached to the threaded portion thereof. Consisting of 11 and
The collar 10 of the screw rod 9 and the mold 13 held by the pipe 13 on the side of the home tie 11 are held at a constant distance from the block side surface 3 (and 3 '). In the case of a normal block, the anchor 7 may be provided at one place in the middle of the block body 2, but the number and the position thereof can be arbitrarily changed. 14 shows base concrete.

When the concrete block having the above structure is used for construction, the block main body 2 is continuously laid on the base concrete 14 installed in advance at the construction site. Next, the external threads of the separator 8 which is a member for fastening the mold are screwed into the female threads 6 that are opened at the bottom of the side surface 3 (or both side surfaces 3, 3 ') of each block body 2, and A predetermined mold 10 is set by the holder 5. After that, concrete is placed between the block body side and the formwork 10 side, where the upper surface of the formwork 10 and the upper edge 4a of the protrusion 4 indicate the position of the construction surface P. Therefore, since the construction surface P is given by the straight line connecting the upper edge 4a of the protrusion 4 to one end and the upper end of the mold 10 to the other end, the trowel finish is also very easy. To do.

(Effect of the Invention) In the device of the present invention, a substantially L-shaped groove C is constructed by a straight line connecting the upper edge 4a of the protrusion 4 provided on the block body 2 and the upper edge 10a of the mold 10. Accurately indicate the plane P. When ink is put into the block body and the construction surface is exposed as in the conventional art, the ink is likely to disappear due to the inclination of the construction surface P, but the protruding portion 4 serves as a reference surface on which the tool is applied and is substantially L between the projection 10 and the formwork 10. The construction surface P of the V-shaped groove C can be formed quickly and accurately.

The block body 2 is an anchor 7 for fastening to the formwork 10.
Since it is integrally provided with the block main body 2, it is easy to pass the separator 8 and fasten the mold 10 to install the mold 10 at a constant interval from the block main body 2, and the work is very easy.

(Effect of the Invention) Therefore, according to the present invention, the concrete pouring work can be performed by the protrusion 4
The construction surface P is very beautifully finished with the upper edges 4a, 10a of the mold 10 as a reference, and the line on the cast concrete in contact with the block body 2 does not become wavy, so that even an unskilled person can have a substantially L shape. Since the groove C of the mold is ideally finished and the anchor 7 is embedded in the block main body 2, the setup work for setting the mold 10 can be performed without trouble, and the construction period can be shortened. Has a great effect.
