Cover of concrete drain block {COVER FOR CONCRETE DRAINAGE BLOCK}

The present invention relates to a cover of a concrete drain block, and is suitable as a cover of, for example, a side block, a U-shaped block, a waterway block, a mud block, and the like. According to the purpose, the assembly is easily performed in a factory or the like, and exhibits a multifunctionality capable of performing selective attachment, so as to efficiently collect rainwater or the like falling on the road.

Background Art Conventionally, a drainage system for collecting and draining rainwater falling on a road has a concrete drain block disposed continuously at the edge of the road or laid across the road.

The side cover which is covered by this side block has what is shown by FIG.

That is, the cover a is made of concrete with a length L ' _{2 of} about 500 mm relatively short in consideration of transportability, and is made of concrete with an approximately equal thickness t' of a cross section, and furthermore, a side end in the longitudinal direction X. The hand-holding hole a ₁ is provided in this. In addition, a reinforcing bar is disposed inside the cover a so that the cover a exhibits structural strength. Then, a plurality of covers (a) are covered in the opening (c) above the one side block body (b) so as to be able to be pulled out. In addition, the side block body (b) is connected to each other via a water collecting container block that is wider than the side block body (b) arranged at predetermined intervals.

Then, for example, when the side block main body b is laid along the road surface E of the road D, the road D may be opened through the handhold hole a ₁ provided in the water collecting container block or the cover a. The rainwater etc. which fell on the road surface are collected, it introduces in a side block body (b), and it drains.

In this way, the rainwater that falls on the road D flows down the road E along the crossing slope θ on the road D, and drains on the road surface without accumulating on the road surface. By ensuring the width of the width of the road (D), there is a request such that safe driving can be performed without disturbing the driving of the vehicle.

In addition, as shown in Fig. 18, in the case of laying the sidewalk J parallel to the road D, it is covered by the U-shaped block d that is continuously placed on the road surface E of the road D, An inclined surface e ₁ is formed on the upper surface, which coincides with the crossing gradient θ of the road D, and a curb portion f is integrally formed on one side of the laying side of the sidewalk J, and the L-shaped side. There is a block (e).

However, the conventional side cover shown in Figs. 15 to 17 has a length L ' ₂ of about 500 mm in consideration of transportability and is formed at about the same thickness t' of a substantially rectangular cross section. The cover (a) in the upper opening (c) with respect to the side block main body (b) should be covered with the side block main body (b), and the work efficiency required for rehabilitation at the installation site is poor and workability Was low. In addition, the cover (a) is formed in a flat surface with an upper surface of the same thickness (t ') having a substantially rectangular cross section, and is covered by the opening (c) of the water collecting container block and the side block body (b) arranged at predetermined intervals in the drainage. Since the rainwater is drained through the hand-holding hole a ₁ provided in the cover (a), the drainage efficiency of the rainwater flowing down the edge E in accordance with the crossing gradient θ of the road D is low. There was a difficulty in drainage. In the case of heavy rainfall, the drainage from the side block body (b) is not sufficient, the rainwater begins to overflow on the edge E, and the road surface of the road D is filled with rainwater, which causes trouble to the vehicle. This impairs safety.

In addition, since the hand opening hole a ₁ is intermittently laid along the road surface E of the road D, the conventional side cover is unobtrusive at the time of driving of the vehicle, and the visibility of the front side is prevented. ) Will be damaged. In addition, when the vehicle is loaded on the upper surface of the cover a, the load is applied to the vehicle so that the cover a collides with the side block main body b to generate noise, and at the same time, to the end of the cover a. Debris was produced by the impact of poetry.

In addition, in order to shape | mold the said conventional side port cover shown in FIGS. 15-17, and the L-shaped ingot block shown in FIG. 18 using concrete, it shape | molds using the exclusive shaping | molding die. For this reason, it is necessary to select a drainage system suitable for the purpose in consideration of the site conditions such as wide and narrow roads, topography, meteorological factors such as soil rigidity and softness and rainfall, and some traffic volume. However, in order to equip all of these drainage facilities, all of the expensive molds must be prepared, and huge equipment costs are required, and the product cost has also become expensive.

The present invention solves the conventional non-compliance, and easily assembled and selectively installed in the factory and the like to cover the cover structural plate of the same shape or cross-sectional shape with respect to the common grating member to fit the application in consideration of the site situation. It exhibits multi-functionality that can be performed, and it has good drainage efficiency, contributes to the safe driving of the vehicle without impairing the driver's forward visibility, and generates no noise such as debris on the end of solid structure without generating noise. In addition, the molding type is inexpensive and does not require a lot of equipment cost, and the manufacturing cost of the product is to provide a cover of the concrete drain block inexpensive.

By inserting the convex part 22a into the concave part 22b, the cover 2 is prevented from shifting with respect to the side block main body 1, and moving.

In addition, although the cover 2 is not shown in figure, it can also be fixed by the fastening bolt or the nut screwed to this fastening bolt instead of the fastening means by the fastening cylinder body 19 and the fastening pin body 20. As shown in FIG.

One embodiment of the present invention is composed of the above configuration, in order to assemble the cover (2) at the factory or construction site, if necessary, the wide and narrow of the laying site of the road (D), the topography, the solid and soft In consideration of the weather conditions such as the amount of rainfall and the amount of traffic of the vehicle, the cover construction plate for the use described below is selected and assembled.

The details of this assembly are described, for example, as shown in Figs. 1 and 3, by selecting and arranging the planar substantially rectangular cover construction plates 4 and 4 having the same thickness t of the substantially rectangular cross section and arranging them in parallel. The common grating member 5 is fitted in the slit 3 formed between the component plates 4 and 4 from the bottom. At this time, the cover part plate 4 is provided with the support parts 6a, 6a extended to the left and right of the support lever 6 which are integrally fixed to the lower surface of the horizontal plate 12 of the grating member 5 at every desired interval K ₁ . The cover 2 is piled up by fitting in the groove part provided in the corresponding part of the lower surface of (4).

The cover 2 assembled in this way is stored in a warehouse and stacked or transported to a construction site. However, the cover 2 is integrated by attaching and attaching the grating member 5 to the two cover structural plates 4 and 4, so that the cover 2 is integrated. The grating member 5 is not inadvertently removed due to vibration or external force from the vehicle being applied. In addition, the grating member 5 is made of a plurality of steel plates arranged in parallel to the longitudinal direction X at intervals, and in the drawing, three transverse plates 12 and a longitudinal direction X with respect to the transverse plates 12. ) Is formed in a planar lattice shape by a plurality of sheets for maintaining the spacing, for example, seven longitudinal plates 13, which are made of steel provided at desired intervals K ₁ , so that the structure is firm and the longitudinal direction (X) ), The cover member plates 4 and 4 can be firmly supported against tension, compression, and twisting in either the direction of the width direction Y and the height direction.

In this way, in order to cover and install the cover 2 assembled at the factory or the like in the opening of the side block body 1, for example, as shown in Fig. 9, the shoulders 1b ₁ , which face the upper side of the side block body ₁ , 1b ₁ ) If the tip of the locking pin body 20 is inserted into the attachment hole 17 provided in the upper portion 15B of the locking cylinder 19 embedded in the locking cylinder 19, the locking pin body 20 is hit by a hammer. The small diameter portion 20A provided at the distal end of the pin body 20 is press-fitted into the small diameter attachment hole 16 through a contact hole 18 communicating with the large diameter attachment hole 17 provided in the locking cylinder 19. do. At this time, the cover 2 is not yet covered by the side block body 1.

After that, if the cover 2 is placed on the side block body 1 without further hitting or catching the locking pin body 20 by the hammer, the load of the cover 2 is applied by the hammering force. The large diameter portion 20B of the pin body 20 is press-fitted into the large diameter attachment hole 17 installed in the upper portion 15B of the locking cylinder 19 so that the locking pin body 20 is coupled to the locking cylinder 19. . In addition, when the cover 2 is covered by the side block main body 1, the upper part 15B of the latch cylinder 19 by the load of the cover 2 has the attachment hole provided in the corresponding location of the cover 2. It fits in 4a and the lid 2 is fixed to the side block body 1. In addition, although not shown in the drawings, the cover 2 may be detachably fixed to the side block body 1 by using a buried bolt and a nut.

In this way, when the side block main body 1 is continuously laid along the road D as shown in FIG. 3, and the cover 2 is piped and fixed, the rainwater which fell on the road surface flows into the road surface E. As shown in FIG. It is lowered and introduced into the side block main body 1 through the grating member 5 from the slit 3 which is formed generally over the longitudinal direction X about the center of the width direction Y of the cover 2. Therefore, the rainwater falling on the road surface of the road D or the like can be drained by the drainage path 1a provided in the side block body 1 efficiently. Therefore, even if there is a lot of rainfall, the road D is flooded or drainage is performed without flooding the roadside E with rainwater.

Moreover, since the cover 2 formed in the same thickness (t, t) of substantially rectangular cross section is covered and installed in the side block main body 1 as mentioned above, even if a load is applied as a vehicle runs, the cover 2 ) Does not generate a collision sound that collides with the side block main body 1.

In addition, the cover 2 is a new construction for road laying paper having a limited area because the cover structural plates 4 and 4 are formed in substantially rectangular cross-sections of the same thickness (t, t), and the upper surface is formed in a flat surface. In the case of forming a or the number of roads (D), the width of the width of the road (D) can be sufficiently secured and the vehicle can be safely driven.

Furthermore, the slits 3 formed between the cover structural plates 4 and 4 of the cover 2 and to which the grating member 5 is fitted are continuously installed on the cover 2 along the road D. Therefore, the visibility of the front is ensured without being unobtrusive at the time of driving of a vehicle, and it can contribute to safe driving.

10 and 11 show that the cover member 4 having a substantially rectangular cross section with the same thickness t ₁ thinner than that described above slightly projects the upper part of the grating member 5 during assembly attachment. At the same time, the cover construction plates 4 'and 4' are formed in a trapezoidal cross section in which the inclined surface portion 7 'facing the slit 3 is formed in an approximately trapezoidal shape. The slits 3 are formed in a substantially rectangular plane of widths W ₁ and W ₂ having different widths and narrownesses in the width direction Y intersecting in X), so that the slit 3 is formed in the longitudinal direction X of the cover construction plates 4 and 4 '. The curb block 30 is formed in the longitudinal direction on the upper surface of the cover member plate 4 provided on the sidewalk J, among the two cover member plates 4 and 4 '. It installed in (X). Then, the side block body 1 is laid along the road D, and the road D and the sidewalk J can be separately placed by the curb block 30 by effectively utilizing a limited road laying paper. A point is a structure different from the said modification, and let it be an action and an effect.

12 is a 3rd modified example of the cover 2 which piled up the heterogeneous and heterogeneous cover structural plate using the common grating member 5. Moreover, FIG.

That is, the cover structural plate 4 provided on the side far from the road D is formed in a plane substantially rectangular shape having the same thickness t of substantially rectangular cross section in the shape as shown in FIG. road (D) a downhill gradient (θ _1), the inclined surface portion (7) cover configurations plate (4A) of the plane is substantially rectangular of other shape is provided on the upper surface of cross-section forms a trapezoidal a toward the slit (3) side, close to the The support levers 6 are disposed in parallel with the slit 3 with respect to the cover configuration plate 4 and are provided at desired intervals K ₁ in a common grating member 5 inserted into the slit 3. By fitting in the groove provided in the corresponding part of the lower surface of the cover structural plates 4 and 4A, the cover 2 of a different type | mold and a release | release is assembled with the cover 2 shown in FIG.

And the cover 2 assembled in this way has the cover structure board 4A which has the inclined surface part 7 of the downhill gradient (theta) ₁ on the upper surface which substantially coincides with the crossing gradient (theta) of the road D. Since it is disposed on the (D) side, the rainwater falling on the road surface of the road D flows down toward the shoulder E according to the crossing gradient 6 of the road D, and then the road D close to the road D side. Slit 3 is inserted into the slit block main body 1 by flowing down the inclined surface portion 7 of the downhill gradient θ ₁ of the upper surface of the cover construction plate 4A provided along the slit 3. As shown in Fig. 3, it is introduced into E) without drainage and is efficiently drained through the drainage path 1a. It is different from the cover 2 in which cover cover plates 4 and 4 are arranged in parallel through the slits 3.

In addition, in the 4th modification shown in FIG. 13, the cover structural plate 4'A provided in the side of the road D among the two cover structural plates piled up by the grating member 5 is a side opening on the side surface. Since a plurality of suitable permeable window holes 8 are provided in communication with the drainage passage 1a in the block body 1, the transverse gradient of the road D on the top of the impermeable layer 9 as a paving material of the road D ( When the permeable pavement portion 10 is laid at θ), a part of the rainwater dropped on the road surface of the road D flows down the road surface toward the road surface E along the crossing gradient θ. In addition, a part of the rainwater which has fallen down penetrates into the water-permeable pavement portion 10, flows down the upper surface of the water-impermeable layer 9 toward the shoulder E, and the road D at the end face 10a of the water-permeable pavement portion 10. It is suitably used to be introduced into the side block body 1 from the water-permeable window hole 8 provided on the side of the cover structural plate 4'A provided on the side, and to be drained by the drainage passage 1a. Therefore, it is advantageous in that the road surface of the road D is drained without being irrigated, compared with the case of using a water permeable material such as asphalt as the pavement material of the road D. In the water-permeable packaging unit 10, aggregates such as gravel, crushed stone, sludge, etc. are used to provide water permeability by providing a continuous gap therein using a binder such as synthetic resin adhesive or cement. Used.

Further, in the fifth modification shown in Fig. 14, the grating member 5 for assembling the two cover member plates 4 and 4 having the same thickness (t, t) having a substantially rectangular cross section and having a substantially rectangular plane is formed. ) Is formed to protrude more than the slit 3 formed between the cover structural plates 4 and 4, so that two covers having a flat surface on the upper surface so as to sandwich the projecting portion of the grating member 5 on the upper surface. By applying coloring or natural stone on the upper surface of the component boards 4 and 4 to the upper surface, the interlocking blocks 11, 11, etc. formed by using concrete can be laid so as to make up makeup or exhibit permeability. Rainwater falling on the interlocking blocks 11, 11, etc. can be drained into the side block main body 1. Therefore, it is suitable for laying drainage paths in public places such as parks, stadiums, factories, or porches of concrete buildings.

In the above description, the lid 2 is formed by two cover construction plates 4,4; 4,4 '; 4,4A; 4,4'A, and the slit 3 is formed of these cover construction plates 4 The grating member 5 is fitted in this slit 3 by being installed in one row between 4, 4 ', 4, 4'; The number of the slits is not limited thereto, and the lid 2 includes the grating member 5 in the slit 3 formed between the lid members while at least three lid members are disposed in parallel to the longitudinal direction X. The fitting member may be installed on the support lever 6 protruding at a desired interval in the width direction Y crossing the longitudinal direction X of the grating member 5.

In addition, in the above description, the slits 3 formed between the cover components 4, 4; 4, 4 '; 4, 4A; 4, 4'A are shown as being formed entirely over the longitudinal direction X. The slits may be formed intermittently with a desired interval in the longitudinal direction X, and the shapes thereof are not limited to those shown in the drawings.

In the above description, the side block main body 1 is representatively described as a drain block, but the drain hole block is not limited to the side block main body 1 but is also used for a cover to be attached to a U-shaped block, a rain water block, a water channel block, or the like. The present invention can be applied.

As described above, the present invention uses a cover structure plate having a shape having the same cross-section or a different cross-section through a slit extending in the longitudinal direction in consideration of the site situation with respect to a common grating member. Since it can be selectively assembled in a factory or the like so as to meet the needs, the versatility can be exhibited and the assembly in the factory or the like can be performed efficiently and easily. In addition, since the slits are formed between the plurality of cover structural plates, rainwater or the like that falls on the road flows down toward the edge of the road, which is a transverse gradient from the road surface, is introduced into the drain block through the slits, and is efficiently drained.

In addition, since the slits are continuously formed on the cover laid along the road, the driver is distracted by the discontinuity of the handholding holes, as in the conventional side cover having the handholding holes. Can contribute to In addition, since the cover is installed in the drain groove block, noise due to the collision with the drain block does not occur and defects such as debris are generated at the end of the cover component plate. Moreover, the shaping | molding die of a cover structural board is simplified in shape compared with the former, and furthermore, since one cover is formed in length corresponding to some of the conventional side cover, it is manufactured at low cost. In addition, since the grating member has a common shape with respect to a cover member of a heterogeneous and heterogeneous shape, and the cover is assembled, the material cost and equipment cost become inexpensive, and the production cost of the product becomes inexpensive.
