DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a gutter block, a gutter wall block with a gutter, and the like. The present invention relates to a gradient groove block forming mold that can be formed as a gradient groove block.

[0002]

2. Description of the Related Art Means for flowing rainwater and drainage include:
Concrete U-shaped groove blocks are often used,
This U-shaped groove block has a disadvantage that it cannot be used where the road gradient and the water channel gradient are different.

[0003] In addition, in the conventional method of forming a slope groove using a concrete block, a block having a flat bottom groove that gradually becomes deeper or shallower without applying a bottom slope is connected and then concreted to fill a step at the site, or high concrete is poured. Blocks with different bottoms are sequentially connected and installed, and cast-in-place concrete is installed at the bottom of the trench according to the slope of the site.

[0004] That is, there are various types of molding forms, such as steel forms for pre-casting, control panel forms for on-site casting, steel forms, and resin forms for extrusion molding. Since it is technically extremely difficult to form a concrete block with a sloped groove, it is better to mold it into a flat bottom groove or a block without a groove bottom and adjust it with cast-in-place concrete at the stage of the forming formwork. It has been considered advantageous.

[0005] To cope with this, there is a precast gutter with a free slope. However, since the bottom of the slope is adjusted with cast-in-place concrete and the slope angle is determined according to the situation at the site, the construction method is flexible. However, there is a drawback that the width of the load-bearing beam set over the upper surface is large and obstructive, and the depth of the block makes it difficult to carry out the construction work, which may lead to construction errors.

[0006]

As described above, adjusting the bottom of the slope groove with cast-in-place concrete is advantageous in that the angle gradient can be determined in accordance with the situation at the site and flexible construction can be performed. However, if the slope is wrong, water will not flow or drainage efficiency will be reduced, which may lead to fatal construction errors.

[0007] Therefore, a high level of skill is required, and a long operation in a narrow slope groove is required.
In addition, if a block with a flat bottom groove is selected incorrectly, the step is too large to be applied to the site, or the step is too small to use more concrete than necessary.

However, forming a slope groove into a block by precast concrete using an angle gradient calculated in advance requires efficient and cost-effective since angle adjustment and depth adjustment must be performed for each individual formwork. The current situation is that they do not accept this.

Therefore, the applicants have disclosed in Japanese Patent Application No. 8-59379 (Japanese Patent Application Laid-Open No. 9-250164) a unit in which each of the units has a bottom slope and a depth of a required angle and is connected to form one slope groove. We have proposed the creation of a gradient groove using a plurality of blocks with grooves, and a forming mold for the block.

However, the one proposed by the applicants in Japanese Patent Application No. Hei 8-59379 (Japanese Patent Application Laid-Open No. 9-250164) also discloses that each of the block gradient grooves constituting a series of unit grooves has the required bottom slope and depth at a required angle. For this reason, it is necessary to prepare a groove-shaped mold having a special shape individually for the number of unit grooves constituting the unit groove.

[0011]

SUMMARY OF THE INVENTION The present invention addresses the above-mentioned problems, and comprises a plurality of unit blocks having different groove gradients designed to form grooves having a predetermined gradient by connection. It can be formed in two molds, and they are connected and laid one after another so that a waterway according to the design gradient can be completed.

As means for this, a pair of side plates having a groove forming die provided with a mechanism for tilting up and down in accordance with the groove gradient of a block to be formed is set on a base, and a pair of side plates having a block edge forming die formed on the inside thereof, A block forming portion is formed by positioning and fixing the end plate that is positioned from both sides to face the base with the forming die therebetween, and cuts and cuts the both ends obliquely in accordance with the groove gradient.

In other words, the bottom gradient and the depth of each of the block gradient grooves constituting the unit groove are tilted up and down according to the groove gradient set on the base, so that different angles are obtained depending on one groove molding die. It is possible to freely set the bottom gradient and the depth of the.

Further, by forming one or both of the pair of side plates so as to be exchangeable and to be able to advance and retreat on the base, the width and the outer shape of the molded block can be freely set, and the top of the side plate can be set. The insertion receiving piece and the lower end support piece for fitting the partition plate at the required positions of the end and the lower end are set to be movable left and right so that the partition position by the pair of the same side plates can be changed, and furthermore, the groove forming die Is detachably supported on the top of the elevating mechanism so that the shape of the groove to be formed and the width of the groove to be formed can be freely set by changing the groove forming die so that one block forming die can be utilized in various ways. I made it. It is also possible to set a plurality of partition plates for determining the length of the molding block and to partition the long molded body into appropriate lengths so that a plurality of unit blocks can be molded at once.

Further, the elevation of the groove forming die is swingably supported on the upper inside of the groove molding die, and a vertical scale indicating the vertical height is arranged in parallel with the vertical rod, and the vertical scale is instructed to control the vertical height. The indicator piece shown is provided at the reference position of the elevating rod, and the indicator piece is configured to move up and down in accordance with the elevating of the groove forming die support. Added easy setting.

[0016]

Embodiments of the present invention will be described below with reference to the drawings. 1 is a base of a formwork, and a tilting elevating mechanism is almost at the center.
A groove forming die 2 provided with 1, 21 is set, and rails 11, 11 for moving the pair of side plates 3, 3 are moved on both sides thereof.

The main body of the groove forming die 2 is constituted by a groove forming plate bent in an inverted U-shape, both ends of which are supported by lifting rods 2a and 2b, and the groove forming plate is inclined by a difference in elevation between 2a and 2b. The bottom slope of the slope groove is set.

The tops of the elevating rods 2a and 2b are supported by a support shaft 22 which is removably inserted into the upper part of the groove forming plate, and supports the groove forming plate in a swingable manner. Fluctuations in the tilt angle between the elevating rod support and the groove forming plate caused by the differential elevation of the groove forming plate are absorbed by this swing.

A male screw 23 is engraved at the base of the elevating rods 2a and 2b, and a female screw hole and a screw are engraved in an elevating operation ring 24 rotatably set on the elevating bases 2A and 2B. In addition, by the rotation of the lifting operation ring 24, the lifting rod moves up and down in the lifting rod receiving hole 25 provided in the lifting bases 2A and 2B. It is needless to say that this lifting and lowering may be performed by a mechanism such as an oil cylinder or the like instead of screwing and lowering.

Further, an indicator piece 26 attached to the reference position of the elevating rod is adapted to move up and down in accordance with the elevating of the groove forming die supporting portion. Since the indicating piece 26 indicates the elevating scale 27 provided in the section and indicates the elevating altitude of the groove forming plate, the bottom gradient and depth of the inclined groove can be confirmed by the elevating scale.

Further, since the groove forming plate is detachably mounted on the tops of the elevating rods 2a and 2b, the groove forming plate may be replaced as necessary to change the groove width and the shape of the groove. Is available.

The side plates 3, 3 are provided with a base 31 on which wheels 32 are mounted on the lower surface projecting in an L-shape.
On the opposing surfaces, a mold 33 with a lid formed on the edge of the block is attached and formed.

Reference numerals 4 and 4 denote partitioning gable plates whose both ends are cut obliquely in accordance with the groove gradient. The length of a molding block is set inside the side plates 3 and 3 which are positioned from both sides with the groove forming die 2 interposed therebetween and face the base 1. Is fitted into the fitting groove 34 set corresponding to the above, and is dropped into the mold to form both ends of the mold. In addition, a plurality of partition blocks 4 for determining the length of the forming block are set between the side plates 3 and 3 which are set to be long, and the long formed body can be divided into appropriate lengths and a plurality of unit blocks can be formed at once. It is also possible to do so.

The fitting grooves 34 of the partition slats 4, 4 are formed by inserting the insertion receiving piece 35 into which the partition slats are fitted and the support plate 36 at the lower end of the plate.
3 is set at required positions of the top end and the bottom end, and the insertion receiving piece 35 and the bottom end supporting piece 36 are set so as to be movable to the left and right of the side plates 3 and 3, and the length of the molding block is required It can be adjusted according to.

In the above-configured formwork, the groove forming die 2 is set in an inclined manner in accordance with the groove shape of each of the unit blocks in which the required angle of bottom and the depth are distributed corresponding to the unit grooves to be formed. Then, the side plates 3, 3 are opposed to each other from both sides, and the partition plates 4, 4 are dropped into both ends in the mold to form a molding form.

By filling the formed mold with concrete H, first, a gradient groove block A as a unit is formed, and after removing this, a groove shape of the gradient groove block B as a unit is further formed. Accordingly, if the groove forming die 2 is set to be inclined, the units A, B, C,... Can be formed one after another by one mold.

Further, if a plurality of mold frames are used, it is of course possible to carry out the mass production system without resetting the inclination of the groove forming mold 2 each time. Even in this case, the groove forming die 2
Since the inclination setting can be freely changed, it is possible to repeatedly cope with blocks having different unit designs.

Further, by making the side plates 3 and 3 replaceable, for example, by using the side plate 3 and the partitioning gable plate 4 as shown in FIG. It can also be applied to blocks with gutters.

Since the present invention is configured as described above, the gradient groove blocks A, B, C,.
If the groove forming mold is adjusted as a slope groove forming unit, the groove forming mold is adjusted and formed stepwise by a mold set with inclination, classified according to the change of each depth and angle gradient, and the connection order is indicated by the code. By simply arranging the blocks on site according to the order shown, a predetermined sloping groove is formed.Conventionally, the most skillful and labor-intensive concrete pouring work on the groove bottom can be omitted. Slope grooves can be created only by required operations such as filling.
