Description

  The present invention relates to a formwork device for forming, for example, a concrete side groove 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 demolded to form a side groove. A block is formed.

By the way, as described in Japanese Patent No. 29987575, a side groove block with a water guide member that guides surface water in contact with the side wall into the side groove has been recently requested and proposed.
The side groove block with a water guiding member is formed with a hole or a notch at a predetermined position on one side of the upper outer surface of the side groove block, thereby forming an introduction groove space and communicating with the inner running water passage of the side groove block. Yes.
Further, a water guide member that is a hard plate-like base and has a plurality of holes or notches for water transfer between the front and back surfaces is mounted in the introduction groove space, thereby forming a side groove block with a water guide member. ing.
However, in such a conventional side groove block with a water guide member, first, the auxiliary mold for forming the hole or notch is attached to the mold to form a side groove block having a hole or notch at a predetermined position, and thereafter In addition, it is completed by attaching the water guide member to the position by bonding or using a fastener. As for the installation of the water guiding member, there are ones that are performed at the time of on-site enforcement of the gutter block, and ones that are performed at the time of factory manufacture. In any case, however, it has been pointed out that the formation of such a side groove block with a water guiding member is extremely laborious and costly compared to the formation of a standard side groove block.

The side groove block formwork device according to the present invention and the side groove block formed by the formwork device can simplify and reduce the cost of a drainage device including a water guiding member on the side of a so-called side groove block. It has an excellent effect that it can be integrally 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 or substantially rectangular cross section, and its front-rear direction is supported by a front mold frame (not shown) and a rear mold frame (not shown). It is installed in a so-called floating state near the center of the space. Thus, the inner mold 3 forms a hollow portion that becomes a flow path in the side groove block. Further, at least one side of the side wall frames 2 and 2 is formed of a magnetic material such as iron.
Next, the net member 4 is composed of a base portion 11 and anchor portions 12 and 12 that are bent from both ends of the base portion 11 in the width direction, and has a substantially U-shaped cross section. Here, the material and form of the net member 4 are preferably a punched metal or wire net bent, a punched metal or metal net with an anchor, a plastic plate having a net-like hole formed on the outer side surface, or the like.

Next, the code | symbol 5 shows a punching formwork. The punching mold 5 is a mold for forming the introduction groove space, and is formed in a so-called wedge shape having a substantially square cross section so as to become narrower from one end in the longitudinal direction toward the other end. Yes. This takes into account the ease of removal of the punching mold 5 when the mold is removed. Then, the net member 4 is clamped and fixed to the side mold frame 2 with the long side of the substantially trapezoidal cross section as the bottom surface 6 side, thereby forming the net introduction groove space. By such arrangement of the punching mold 5, the water collecting side hole of the introduction groove space can be formed wider than the communication hole side. This is because water can be collected in a wide range in the upper part of the side groove.
Further, as described above, in order to form the meshed introduction groove space, it is necessary for the punching mold 5 to fix the mesh member 4 to the side mold 2 by clamping. 9 and 10, a bolt screw hole 16 is provided on the bottom surface 6 of the punching mold 5, and the tip of the bolt 15 is passed through the side mold 2 mounting hole and the net member 4, The aspect which couple | bonds and fixes is shown.
Moreover, there exists a connection method using a magnet other than the connection method using such an attachment member. FIG. 6 shows an embodiment in which a plurality of magnets 7 are mounted on the bottom surface 6 side of the open mold 5. Here, when the magnet 7 is mounted, it is preferable that the magnet 7 is embedded and mounted so that the bottom surface 6 of the punching mold 5 is flush. Further, in the case where a plurality of magnets 7 are mounted on the bottom surface 6 side of the punching mold 5 as described above, the material of the punching mold 5 can be composed of a synthetic resin member such as plastic or rubber, and the cost is low. There is an advantage that it can be created. On the other hand, when the punching mold 5 is made of a paramagnetic material such as an iron member, the magnet 7 is not necessarily mounted so as to be exposed on the bottom surface 6. What is necessary is just to be mounted in the punching mold 5.
Further, without attaching the magnet 7 to the opening mold 5, the material itself of the opening mold 5 may be the magnet 7 or a magnetized metal member.

  As can be understood from FIGS. 5 and 6, the bending angle between the base 8 and the bent piece 9 on one side is about 90 degrees, but the other side of the base 8 and the lower side of the mold is located. The bending angle with the bending piece 10 is expanded from 90 degrees, and is set to an angle of about 100 degrees or more. This is because the corners of the manufactured side groove block on the upper side of the side groove are easily damaged when a recess is formed at an angle of about 90 degrees.

  The use state of the present invention will be described below.

  As shown in FIGS. 1, 9, and 10, the net member 4 and the punching mold 5 are held at the lower longitudinal end of the side mold 2. This is to hold the mesh member 4 and the punching mold 5 in the mold apparatus by means of bolts 15 of attachment members that connect the punching mold 5 and the side mold 2.

Specifically, at the lower longitudinal end of the side mold 2, the base 11 of the mesh member 4 is attached to the inside of the side mold 2, and the longitudinal direction of the base 11 is the longitudinal direction of the side mold 2. It is arranged so as to be substantially parallel to. Thereafter, the bottom mold frame 5 is formed with the bottom surface 6 in which the screw holes 16 for bolts are formed facing the base 11 of the mesh member 4 and the narrow side toward the center side in the longitudinal direction of the side mold frame. 5 is arranged such that the lower side 14 in the longitudinal direction of the bottom surface 6 is substantially parallel to the longitudinal direction of the base 11 of the mesh member 4.
Then, the tip of the bolt 15 is passed through the side mold 2 mounting hole and the mesh member 4 and is hinged to the bolt screw hole 16 to be connected and fixed. In this way, the net member 4 is clamped and fixed by the open mold 5 and the side mold 2.
In this state, concrete is placed in the mold. Thereafter, when the concrete is solidified and the mold is removed, the bolts 15 are pulled out, the side mold 2 is opened and opened, and the open mold 5 is pulled out in the longitudinal direction of the side mold 2. That is, since the narrow side of the wedge-shaped open mold 5 is on the inside and the wide side is positioned on the outside, the open mold 5 can be easily removed when the mold is removed. Then, a netted introduction groove space is formed at the drawing portion.

  As shown in FIGS. 1 and 7, the net member 4 and the punching mold 5 are held at the lower end in the longitudinal direction of the side mold 2 formed of a magnetic member. This is because the net member 4 and the punching mold frame 5 are held in the mold apparatus by an attractive force between the punching mold frame 5 formed of the magnet itself or attached with the magnet and the side mold frame 2 made of magnetic metal. To do.

Specifically, at the lower longitudinal end of the side mold 2, the base 11 of the mesh member 4 abuts the inside of the side mold 2 and the longitudinal direction of the base 11 is substantially the same as the longitudinal direction of the side mold 2. Arrange them so that they are parallel. Thereafter, the bottom surface 6 of the punching mold 5 is directed to the base 11 of the mesh member 4 and the narrow side is directed to the center side in the longitudinal direction of the side mold frame. It arrange | positions so that it may become substantially parallel to the base 11 longitudinal direction of the net | network member 4. FIG.
In this way, the net member 4 is clamped and fixed by the punching mold 5 and the side mold 2.
In this state, concrete is placed in the mold. After that, when the concrete is solidified and the mold is removed, when the side mold 2 is opened, a physical distance is generated between the open mold 5 and the side mold 2 and the attractive force due to the magnetic force does not reach. Therefore, the punching mold 5 is pulled out to the outside in the longitudinal direction of the side mold 2. That is, since the narrow side of the wedge-shaped formwork 5 having a wedge shape is on the inside and the wide side is located on the outside, the formwork 5 can be easily removed when the formwork is removed. In addition, a netted introduction groove space is formed at the drawing portion.

Next, FIG. 8 shows a third embodiment. The difference from the second embodiment is that a magnetic member is not used for the side mold 2, the opening mold 5 is not formed of a magnet itself, and a magnet is not attached. And a point where the open mold 5 and the net member 4 are clamped and fixed by attaching an external magnet 13 to the outside of the side mold 2.
Referring to the embodiment of FIG. 8, the net member 4 and the punching mold 5 are held at the lower longitudinal end of the side mold 2. This is because the net member 4 and the punching mold 5 are brought into the mold apparatus by the attractive force between the external magnet 13 mounted on the outer surface of the side mold 2 and the punching mold 5 made of a magnetic member. It is to hold.

Specifically, at the lower longitudinal end of the side mold 2, the base 11 of the mesh member 4 abuts the inside of the side mold 2 and the longitudinal direction of the base 11 is substantially the same as the longitudinal direction of the side mold 2. Arrange them so that they are parallel. Thereafter, the bottom surface 6 of the punching mold 5 is directed to the base 11 of the mesh member 4 and the narrow side is directed to the center side in the longitudinal direction of the side mold frame. It arrange | positions so that it may become substantially parallel to the base 11 longitudinal direction of the net | network member 4. FIG. Then, an external magnet 13 is attached to the outer surface of the side mold 2.
In this way, the mesh member 4 is clamped and fixed by the external magnet 13 and the punching frame 5.
In this state, concrete is placed in the mold. After that, when the mold is removed after the concrete is solidified, if the side mold 2 is opened, a physical distance is generated between the punching mold 5 and the external magnet 13, and the attractive force due to the magnetic force does not reach. Therefore, the punching mold 5 is pulled out to the outside in the longitudinal direction of the side mold 2. That is, since the narrow side of the wedge-shaped formwork 5 having a wedge shape is on the inside and the wide side is located on the outside, the formwork 5 can be easily removed when the formwork is removed. In addition, a netted introduction groove space is formed at the drawing portion.

Next, FIGS. 3, 4 and 11 show a side groove block formed by the formwork apparatus of the present invention. The mesh introduction groove space is formed in a half-opened state at both ends in the block longitudinal direction, and the groove lower side is formed with a downward slope from the block longitudinal direction center side to the end side. Moreover, the communicating hole which connects the inner side flowing water channel | path of this block and the introduction groove | channel space with a net | network is also formed in the block longitudinal direction both ends cross-section state by the half opening state. Therefore, by connecting the side groove block to another side groove block, the meshed introduction groove space is formed as one closed space in which the groove lower side is V-shaped. In addition, the communication hole is formed as a single hole and is formed at the lowermost part of the lower side of the groove, so that the drainage collected from a wide range of the upper part of the side groove can be smoothly flowed into the inner flowing water passage. .
Thus, in the side groove block formed by the formwork apparatus of the present invention, one integrated water guide member is formed on the connection surface by connecting and laying the side groove block.
Thus, a concrete plate-like sealing block that seals the meshed introduction groove space and the opening portion of the communication hole at the end of the block is installed at the end of the block. As a result, a water guide member having a size that is ½ that of a normal connection surface is formed at the outermost end and performs a predetermined function.
