Description

The present invention relates to a formwork device for forming a concrete side groove block, for example, and a side groove block formed by the formwork device.

Conventionally, the side groove block made of concrete is formed by a formwork device for the side groove block.
That is, for example, the bottom mold is installed in a horizontal direction, and a pair of side molds are opened and connected to each other at a certain interval on the bottom mold, and the bottom mold and An inner mold having a substantially reverse egg-shaped cross section for a water channel is installed and formed at a substantially central portion of the space formed by the pair of side molds.

  In general, the formwork device including the front and back formwork is assembled into a substantially box shape, and the formwork device is filled with concrete and solidified, and then the formwork device is removed from the mold to form side grooves. A block is formed.

Incidentally, a gutter block with a drainage device described in Japanese Patent No. 2888264 has been recently demanded.
In the side groove block with the drainage device, a substantially horizontal lateral groove is formed on one side of the upper outer surface of the side groove block, and a drainage hole that communicates the lateral groove and the inner running water passage of the side groove block is located at a predetermined position. Is provided.
Further, a so-called water-permeable pipe is inserted along the lateral groove, thereby forming a side groove block with a drainage device.
However, in such a conventional side groove block with a drainage device, first, the auxiliary mold for forming the horizontal groove is attached to the mold, a horizontal groove is formed at a side position of the side groove block, and then a water permeable pipe is inserted into the horizontal groove. Therefore, in order to form such a side groove block with a drainage device, there is a problem that work is extremely troublesome and a cost is increased because a water-permeable pipe is used.

Japanese Patent No. 2888264

Thus, the present invention was devised in order to solve the above-described conventional problems, and is a side groove block mold that can be formed easily and at low cost on the side of a so-called side groove block. The object is to provide a frame device and a side groove block.

The side groove block formwork device according to the present invention and the side groove block formed by the formwork device are:

It is characterized by this.

The side groove block formwork device according to the present invention and the side groove block formed by the formwork device can be easily and inexpensively provided with a drainage device including a drainage groove on the side of the so-called side groove block. It has an excellent effect that it can be formed.

Hereinafter, the present invention will be described based on embodiments shown in the drawings.
The side groove block mold apparatus according to the present invention includes a bottom mold 1 installed in a horizontal direction, and a pair of side molds 2 and 2 erected on the bottom mold 1 at intervals. The inner mold 3 is installed in a space surrounded by the bottom mold 1 and the side molds 2 and 2.

  Here, the inner mold frame 3 is configured to have a substantially oval cross section, and its front-rear direction is supported by a front mold frame (not shown) and a rear mold frame (not shown), and the enclosed space. It is installed in a so-called floating state in the vicinity of the center. Thus, the inner mold 3 forms a hollow portion that becomes a flow path in the side groove block.

  Reference numeral 4 denotes a slit forming mold, and the slit forming mold 4 forms a slit communicating with the flow path from the upper surface of the side groove block.

  Next, the code | symbol 5 shows the concave groove production member with a net | network. The grooved member 5 with a net is a groove-forming member having a substantially U-shaped cross section with a base 6 having a long belt shape and bent pieces 7 and 8 bent in the same direction from the width direction of the base 6. 9 is provided first.

  Here, the material of the concave groove forming member 9 is not limited at all, and it may be composed of a synthetic resin member such as plastic or a metal member such as iron.

  Further, as can be understood from FIG. 1, the bending angle between the base 6 constituting the concave groove forming member 9 and the bent piece 7 on one side is about 90 degrees, but it is located on the lower side of the mold. The bending angle between the base portion 6 and the bent piece 8 on the other side is expanded from 90 degrees and is set to an angle of about 100 degrees or more. This is because if the groove upper side of the manufactured side groove block is formed with a concave groove at an angle of about 90 degrees, the corner portion is easily damaged.

  Further, the concave groove creating member 5 has a net member 10 that closes the opening of the concave groove forming member 9.

  The mesh member 10 includes a closing portion 11 that closes the opening, and anchor portions 12 and 12 that are bent from both ends of the closing portion 11 in the width direction.

  As shown in FIGS. 1 to 3 and 5, a bolt-shaped attachment member 13 that penetrates from the outside to the inside of the side mold 2 is attached below the side mold 2. The tip end side of the mesh is passed through the base 6 of the meshed groove forming member 5 and a nut 14 is screwed to the tip to form the meshed groove forming member 5 into the mold. It is assumed that it is held in the frame device.

  In this way, the meshed groove forming member 5 is attached in the longitudinal direction of the side mold 2 on one side. Accordingly, a plurality of mounting members 13 are also mounted at a predetermined interval in the longitudinal direction of the one side mold 2.

Here, FIG. 5 to FIG. 14 explain how to attach the meshed groove forming member 5 to the one-side mold 2, and the embodiment of FIG. 6 will be explained first and will be understood from FIG. 6. As described above, a protruding bar 15 that protrudes from the base 6 in the vertical direction from a substantially central position in the width direction of the base 6 constituting the concave groove forming member 9 is provided. Is inserted and protrudes to the outside of the side mold 2.
And the front-end | tip part is latched on the outer side of the side mold frame 2, and the netted groove forming member 5 is fixed in the mold apparatus. And when removing the side formwork of a formwork apparatus, it is only necessary to remove or cut the said securing part. It is assumed that a plurality of protruding rods 15 are provided at predetermined intervals in the longitudinal direction of the base portion 6.
Next, the example of FIG. 7 will be described. In this embodiment, the double-sided tape 16 is attached to the outside of the mesh member 10 and the inside of the side mold frame 2, and the meshed groove forming member 5 is attached to the side mold frame 2. It is a thing. After the mold release, the double-sided tape 16 may be peeled off.
As shown in FIG. 11, the fixing and fixing of the concave groove forming member 9 and the net member 10 can be carried out on both sides if they are fixed using an adhesive, fixed by welding, or fixed by fitting. The groove forming member 9 is not detached from the net member 10 fixed with the tape 16.
In the embodiment of FIG. 8, a magnet 17 is attached to the outside of the side mold 2, and a netted groove forming member 5 made of a so-called magnetic material is installed inside the side mold 2 by using the attractive force of the magnet 17. It is supposed to be held and fixed.

  That is, the net member 10 made of a magnetic material is attached and fixed to the inside of the side mold frame 2 by the attractive force of the magnet 17. Furthermore, it is still preferable if the concave groove forming member 9 is formed of a magnetic member such as iron.

Even if the concave groove forming member 9 is not formed of a magnetic member, if the concave groove forming member 9 is attached to and fixed to the net member 10 made of a magnetic material, the netted concave groove forming member 5 as a whole is formed as a side mold. 2 can be fixed inside. Here, as described above, the mesh member 10 and the recessed groove forming member 9 are fixed by fixing the mesh member 10 and the recessed groove forming member 9 with an adhesive, welding, or fitting. It becomes fixed.
Next, the embodiment of FIGS. 9 to 10 will be described. For example, the side groove block manufactured in this embodiment is a so-called box culvert type side groove block, and as is understood from FIGS. 9 and 10, an inner mold 3 and one side mold 2 are used. The meshed groove forming member 5 is installed in a formwork apparatus. That is, a spacer 18 that can be held between the inner mold 3 and the side mold 2 on one side is prepared, and a meshed groove forming member 5 is attached to the tip of the spacer, and the side mold 2 is closed. The meshed groove forming member 5 is installed inside the side mold 2 using a pressing force.
By the way, the netted groove forming member 5 constituted by the groove forming member 9 and the net member 10 may have the structure shown in FIGS. In FIG. 12, the concave groove forming member 9 is formed by bending the tip portions of the pair of bent pieces 7 and 7 inward. The mesh member 10 is stored in the concave groove by bending it into a U-shaped cross section. Thus, the net-shaped groove forming member 5 configured as described above is very convenient for transportation and movement, and can be easily attached as a whole.
In the example shown in FIG. 13, the groove forming member 5 is integrally formed of metal or plastic, and a plurality of through holes 19 are formed on one side by punching or the like. If it is what is called the netted groove creation member 5 which consists of such a structure, durability in use can further be improved. Moreover, the external appearance after attachment is also preferable.
