The present invention relates to a lid and a molding method thereof.

[0002]

2. Description of the Related Art Conventionally, drainage components such as concrete gutter blocks, drainage gutters and sewage basins laid to drain rainwater beside roads and pavements are formed of steel to make walking safe. There is a case where a lid part made of grating or concrete and provided with a large number of holes is covered.

[0003] The lid parts are not limited to those made of steel or concrete, and are made of natural stone or crushed stone, clay or the like, or granular aggregate such as ceramic or sludge for collecting rainwater or the like. It is also conceivable to manufacture a water-permeable lid part in which a water-permeable gap is communicated at least in the thickness direction of the lid body by bonding using a binder such as a synthetic resin or cement.

[0004]

However, the above-mentioned grating or concrete lid parts are provided with drain holes for collecting and pouring rainwater or the like into the side gutter blocks or the drain gutters. In this case, the heel of the high heel was inadvertently fitted in the drain hole, or the walking stick of a pedestrian using a cane was stuck in the drain hole, causing inconvenience such as stumbling. .

[0005] Further, dust, leaves, sand, mud, etc., such as leaves, flows into drainage components, such as gutter blocks, together with rainwater from a large number of grid-shaped drain holes formed in the grating, so that dust is contained in the gutter blocks. Etc. tend to accumulate and clog,
May interfere with drainage. In addition, the decay of the garbage and the like caused a rotten smell around the garbage, which was unsanitary.
For this reason, it is necessary to occasionally open the lid part such as the grating and clean the inside of the drainage part such as the gutter block, and the cleaning work is troublesome.

[0006] Moreover, since the steel grating or concrete lid parts are heavy, a large amount of labor is required when carrying or carrying out work or when opening and closing the lid parts during cleaning. The efficiency was poor.

[0007] The above-mentioned lid part, which is made by binding granular aggregates such as natural stones or crushed stones thereof with a binder such as synthetic resin or cement, and having at least a water-permeable void in the thickness direction, is made of a material such as grating or concrete in terms of weight. It has the advantage of being lighter in weight than lid parts made of steel, but when subjected to an impact such as an earthquake, entry of a vehicle, or a large load, it is liable to cause chipping and cracking and is structurally vulnerable. As described above, the lid part in which the granular aggregate such as the natural stone or the crushed stone is bonded by the synthetic resin, ignoring the strength by ignoring the strength of the ratio of the installation area of the water permeable void to the surface area from the viewpoint of structural weakness. It was not possible to increase the water permeability by increasing the size in the dark.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS One embodiment of the present invention will be described below with reference to FIGS. 1 is a gutter main body as a drainage part,
The gutter main body 1 is a publicly known one formed of concrete, and flange step portions 1a, 1a on which the lid main body 2 described later is removably covered are formed substantially at the upper left and right sides.

A cover body 2 is detachably covered with the gutter body 1. The cover body 2 has a substantially rectangular or substantially square base member 3 made of concrete containing reinforcing fibers.
And a surface layer 7 which is integrally formed on the surface of the base portion 3 and in which the water-permeable voids 6 are formed at least in the thickness direction by binding the granular aggregate 4 with a binder 5 made of a synthetic resin.

In this embodiment, the size of the lid main body 2 is such that the vertical length L is about 500 mm and the horizontal length L is so as to facilitate transportation and movement by hand. 'The plane has a substantially rectangular shape with a maximum width of about 700 mm and a thickness M of about 100 mm.

In the present embodiment, the base portion 3 is formed in a substantially rectangular plane as shown in FIG. 1, and an upright wall portion 3a for surrounding the outer edge portion 7a of the surface layer 7 is formed around the base portion. On the lower surface of the base 3, a raised bottom 3b is
It is designed to be lighter by being formed in the direction in which it is laid.

The fibers mixed into the concrete of the base portion 3 include inorganic fibers such as glass fibers and carbon;
Metal fibers such as stainless steel and fibers such as synthetic resin are listed. By mixing these fibers into concrete, the concrete is cured and solidified, and then the compression, tension, impact strength, toughness, etc. are increased.

As the aggregate 4 used in forming the surface layer 7 having water permeability, for example, relatively square particles of natural stone or crushed stone, fired Akadama clay, and ceramics are used. Is done. And this aggregate 4
Has a particle size of 3 when natural stone or its crushed stone is used.
Particles having a particle size of about mm to 10 mm are used, and particles having a particle size of about 1 mm to 5 mm are used when ceramics or the like are used. If natural stones or ceramics of various colors are used for the aggregates 4, the colors can be changed to match those of the town.

A binder 5 for binding the aggregate 4
Examples of the synthetic resin used include epoxy-based adhesives and urethane-based unsaturated polyester-based adhesives.

Then, a synthetic resin binder 5 is added to the aggregate 4.
Are mixed sufficiently and uniformly at a ratio of about 100: 3 to 15 (weight ratio), and the mixture is allowed to stand, whereby a surface layer 7 having water-permeable voids 6 at least in the thickness direction is obtained as shown in FIG. The porosity of the water-permeable void 6 is 15 to 25 when natural stone of the above-mentioned particle size having a relatively angular shape or crushed stone thereof is used.
%, And when a ceramic having the above particle size is used, it is formed to about 10 to 20%. Moreover, the porosity of the water-permeable voids 6 can be changed according to the mixing ratio of the binder 5 of the synthetic resin.

The water permeability of the surface layer 7 formed with a porosity of about 15 to 25% using the natural stone or the crushed stone of the above-mentioned particle size is about 4.5 to 5.5 × 10 ^-2 (cm / sec). The water permeability of the surface layer 7, which is formed to have a porosity of about 10 to 20% using the ceramic having the above particle size, is 4.0 to 5.0 × 10 ^-2.
(cm / sec).

In order to mold the lid body 2, first, concrete FC containing reinforcing fibers is poured into a mold to form an upright wall portion 3a at the outer peripheral edge of the upper surface in FIG. A plurality of drain holes 8 are provided in the vertical wall 3a, and the drains 8 are inclined toward the drain holes 8 between the drain holes 8 inside the vertical wall 3a at the joint surface with the surface layer 7 and between the adjacent drain holes 8. The base portion 3 having the water slope portions 9 and 9 'is formed.

For example, as shown in FIG.
A concrete FC containing reinforcing fibers containing the above fibers is cast into a mold frame K composed of a female mold K1 and a female mold K2, and a pressure of about 50 kgf / cm ² is applied to the concrete FC containing reinforcing fibers to discharge excess water. Then, there is a method by a press method of forming the base portion 3. As a second method for molding the base 3, as shown in FIG. 9, a concrete FC containing reinforcing fibers is poured into a male mold K'1 below the formwork K ', and then a female mold K' is formed. '2 is pushed into the fiber reinforced concrete FC in the male mold K'1 to cure and solidify, thereby casting the base 3 upside down. Further, as a third method, as shown in FIG. 10, the reinforcing fiber concrete FC is placed in a formwork K ″ in which a male mold K ″ 1 is slidably combined with a female mold K ″ 2 installed horizontally. After casting, curing and solidifying, there is a casting method in which the male mold K "1 is slid and the base 3 is molded.

Thereafter, as shown in FIG. 8, a net N is superposed and laid on the upper surface of the base 3 formed as described above. The reason why the net N is interposed between the base portion 3 and the surface layer 7 is that the aggregate 4 forming the surface layer 7 falls into the drain hole 8 formed in the base portion 3 in the next step. In order to prevent the drainage hole 8 from being clogged and to reduce the drainage efficiency, the synthetic resin binder 5 for binding the aggregate 4 adheres to the net N or flows downward through the mesh of the net N. Thereby, the bonding strength between the base portion 3 and the surface layer 7 is increased. Examples of the net N include those formed of glass fibers, inorganic fibers such as carbon, metal fibers, synthetic resin fibers, and the like.

At this time, before the net N is polymerized on the surface of the base portion 3, a primer treatment is performed on the base portion 3 to improve the bonding strength between the water-permeable surface layer 7 and the base portion 3 containing the reinforcing fibers. Should be applied to the surface. This primer treatment
This is a process for assisting the adhesion between the base 3 and the surface layer 7.

For this purpose, concrete FC containing reinforcing fibers as an inorganic material for forming the base portion 3 at the same time as combining the aggregate 4 forming the surface layer 7 with the aggregate 4 and the synthetic material as the organic material are formed. There is a chemical method for increasing the affinity between different materials and the surface layer 7 which is a kneaded product of the resin and the binder 5 to obtain strong adhesion. Examples of the binding material for increasing the affinity include a binder 5 such as an epoxy-based or urethane-based binder.
It is desirable to use a material of the same type as that described above.

As a method for further improving the adhesion between the base portion 3 and the surface layer 7, the surface of the base portion 3 is subjected to surface roughening by grafting or shot processing to secure the adhesion and to bond the binder 5. There are mechanical ways to increase power. Then, by the chemical method and / or the above-mentioned mechanical method, it is possible to secure reliable adhesion between the base portion 3 and the surface layer 7.

Further, as shown in FIG. 8, a kneading material obtained by kneading the granular aggregate 4 with a synthetic resin as the binder 5 is poured into the upright wall 3a of the base portion 3 to obtain the granular aggregate. 4 is bonded with a synthetic resin binder 5 to form a surface layer 7 provided at least in a thickness direction in such a manner as to communicate with a water-permeable gap 6 on the upper surface of the base portion 3 via the net N laid at the joint surface portion. (See FIGS. 1, 2 and 5).

In this embodiment, as shown in FIGS. 2 and 3, the raised bottom portion 3b is located below each drain hole 8 so that its central portion is most deeply recessed and has a downward slope in the left-right direction. Of a substantially arcuate arcuate section 3b ₁ ,
3b ₁ and draining slopes 3b ₂ , 3b ₂ connected to the outer ends of the arcuate slopes 3b ₁ , 3b ₁ , so that a plurality of drain holes 8 provided in the base 3 can be used to form the side grooves. Body 1
Some of the rainwater and the like drained into the interior of the building do not become water droplets due to surface tension and stagnate in one place, but move smoothly along the bow-shaped inclined portions 3b ₁ and 3b ₁ in the left-right direction by their own weight. After that, it is dropped into the gutter main body 1 through the draining slope portions 3b ₂ , 3b ₂ , so that draining is performed efficiently.

The reason why the raised bottom portion 3b is formed on the lower surface of the base portion 3 of the lid main body 2 in the direction in which the lid main body 2 is laid is that the base portion 3 is made thin so as to withstand the strength. The weight of the base member 3 is increased and the thick portions 3c, 3c are secured to the left and right edges of the base portion 3 so as to be substantially opposed to each other. To prevent cracks, cracks, etc., and to make the structure more robust, and the residence time of fine dust and the like flowing by rainwater flowing through the water-permeable gap 6 in the surface layer 7 formed on the upper surface of the base portion 3. This is to make drainage more efficient by shortening the length.

Numerals 8 are formed in the standing wall portion 3a of the lid main body 2 in a plurality of columns, for example, as shown in FIG. 1 and FIG. The drain hole 8 is formed in a substantially rectangular plane as shown in the figure, but is not shown in the figure. In order to drain the water into the gutter main body 1 as a drainage part after collecting the water, the drainage part is formed in a substantially trapezoidal cross-section diverging downward as shown in FIGS. Or, although not shown, it is formed in a cylindrical shape.

As shown in FIG. 1, the drainage holes 8 are determined by determining the hole area S 'of the drainage holes 8, the number of installations, the installation location, and the like with respect to the surface layer 7 having a flat surface S having sufficient strength. In addition, since it is possible to drain rainwater and the like flowing from any direction with respect to the lid body 2 on average and quickly, and because there is no difference in the installation location and the installation number of the drain holes 8, dust, fine dust,
It is designed to make it harder to block sand, mud and the like, and to make it easier to remove dust and the like even if it is clogged.

As shown in FIG. 1 to FIG.
Is formed so as to substantially intersect with the laying direction of the lid body 2 because the thin portions located between the thick portions 3c, 3c are structurally rigidly opposed to the thick portions 3c, 3c. This is to eliminate structural inconveniences such as breakage while enduring tensile, toughness and the like, and to make the structure robust.

Reference numerals 9 and 9 'denote water collecting slopes. The water collecting slopes 9 and 9' are provided adjacent to the upper surface and the vertical and horizontal sides of the vertical wall 3a at the joint surface with the upper surface layer 7. By being formed on the upper surface of the base portion 3 between the two rows and five columns of drain holes 8 and 8 so as to be inclined toward the drain holes 8, it descends into the road surface such as a roadway and a pavement and the surface layer 7. After the rainwater, dust, fine dust, etc., which have penetrated into the surface layer 7 through the water-permeable voids 6 in at least the thickness direction of the surface layer 7,
This is for collecting water in a drain hole 8 provided in the base 3.

A surface layer formed by bonding the water collecting slopes 9 and 9 ′ to a base 3 formed of fiber reinforced concrete FC and a granular aggregate 4 by a synthetic resin binder 5. The reason for forming on the joint surface with the surface layer 7 is that water is efficiently collected at the drain hole 8 of rainwater or the like penetrated through at least the thickness direction water-permeable gap 6 provided in the surface layer 7 on the upper surface of the base unit 3. The reason for this is to increase the contact area between the surface layer 7 and the base portion 3 so as to secure the structure between the surface layer 7 and the base portion 3 firmly and securely.

The water collecting slope 9 located inside the standing wall 3a is inclined so as to be inclined toward the outer peripheral edge of the drain hole 8 provided in two rows and five columns, which is closest to the standing wall 3a. It is formed. As shown in FIGS. 2, 3 and 5, this water collecting slope 9 has a steep first slope 9a and a gentle slope second slope formed continuously with the slope 9a. 9b, the installation thickness M ″ of the surface layer 7 formed inside the upright wall 3a is such that the collecting slope 9 is formed only by a single slope toward the drain hole 8. Since the thickness can be sufficiently secured compared to the installation thickness M ' at an equal distance from the outer edge of the lid main body 2 formed in the upright wall portion 3a as shown in FIG. 6, the surface layer 7 receives an impact due to an earthquake or running of a car. Or
Alternatively, when the vehicle is subjected to a large load such as crossing the upper surface thereof, chipping and cracking of the surface layer 7 can be reliably prevented, and the volume of the water-permeable surface layer 7 is increased, and the water-permeable efficiency is improved. You. In addition, it is closest to the outer edge of the base portion 3 facing the roadway or pavement H, and is garbage, fine dust,
Since the flow rate of the water-permeable gap 6 near the outer edge of the surface layer 7, which tends to be impaired due to clogging of sand, mud, etc., can be increased, dust, fine dust, sand, mud, etc. flow out, and water-permeable efficiency is improved. Is done.

One embodiment of the present invention has the above configuration.
The surface of the base portion 3 formed of concrete containing reinforcing fibers and provided in a plurality of rows with a plurality of drain holes 8 substantially intersecting in the laying direction is used to convert the granular aggregate 4 into a synthetic resin binder 5. When wearing high heels or walking with a walking stick, the pedestrian can see the heel portion of the high heel and walking stick covered by the surface layer 7 and enter the drain hole 8 because it is covered by the surface layer 7 joined together. It will not fit and you can walk safely. The surface layer 7 prevents the leaves and relatively large debris from entering the gutter main body 1 as a drainage component through the drainage hole 8.
Is prevented by.

In addition, for example, rain falling on a road or a pavement or rain falling on the surface of the lid body 2 is transmitted through at least the water-permeable gap 6 communicating in the thickness direction by bonding the granular aggregate 4 with a synthetic resin binder 5. It penetrates into the surface layer 7.

On the upper surface of the base portion 3 at the joint surface with the surface layer 7, an upright wall portion 3 provided around the base portion 3 is provided.
From a to the outer edge of the plurality of drain holes 8, and between the plurality of adjacent drain holes 8 among the plurality of drain holes 8, water collecting slope portions 9, 9 'inclined toward the drain holes 8 are provided. Therefore, rainwater and the like that penetrate through the water-permeable gaps 6 formed between the aggregates 4 at least in the thickness direction of the surface layer 7 are collected along the gradient of the water collecting slopes 9 and 9 ′ while being collected. It is guided into the drain hole 8 evenly and reliably and flows down.

At this time, the standing wall 3 provided on the outer edge of the base 3
a, a plurality of drain holes 8 are formed from the standing wall 3a.
Of the water collecting slope 9 provided to the outer edge of the surface layer 7 is formed with a steeply inclined first slope 9a. The flow velocity increases due to the inclination and the surface tension. So small garbage, sand,
The water-permeable gap 6 located at the outer edge 7a of the surface layer 7 near the outer edge of the lid main body 2 where mud and the like are easily collected and clogged is easily clogged with dust and the like, and rainwater and the like are always efficiently drained to the drain hole 8. The water is guided and collected, and flows down into the gutter main body 1.

As shown in FIG. 3, a part of the rainwater or the like flowing down into the drain hole 8 is close to the lower part of the drain hole 8 and the central portion thereof is most deeply recessed, and the cross section of the slope descends in the left-right direction. arcuate inclined portion 3b _1, 3b ₁ of arcuate, arcuate inclined portion 3b _1, 3b draining slope portion 3b ₂ provided continuously to the outer end of _one, the more the 3b ₂ raised portion 3b is formed because, without staying attached to the lower surface of the raised portion 3b, rapidly arcuate inclined portion 3b _1, 3b _1, flows down to the draining slope portion 3b _2, 3b ₂ and draining well ditch body 1 along the, Efficient drainage can be performed.

Further, chipping or cracking is liable to occur due to impact or load, and the outer edge 7a of the surface layer 7 in which the aggregate 4 is bonded by the synthetic resin binder 5
Is protected by the upright wall 3a provided around the base 3 made of the concrete FC containing the reinforcing fiber as described above, as shown in FIGS. Entry into layer 7 is prevented.

The outer edge 7a of the surface layer 7 is surrounded by the upright wall 3a provided around the upper surface of the base 3 as described above, so that the displacement of the surface layer 7 on the same plane of the lid body 2 can be prevented. This is prevented, and the joining surface of the base portion 3 to the surface layer 7 extends from the standing wall portion 3a provided around the upper surface of the base portion 3 toward the outer edge of the drain holes 8 and between the adjacent drain holes 8. A water collecting slope 9, which is inclined toward the drain hole 8,
Due to the formation of 9 ', the bonding surface of the base portion 3 to the surface layer 7 is different from a mere flat surface, but becomes uneven, and the contact area between the lower surface of the surface layer 7 and the upper surface of the base portion 3 is increased. When the friction coefficient increases, the base portion 3 with respect to the surface layer 7 is increased.
Since the net N is laid and reinforced on the joint surface of the base member 3 to increase the degree of bonding between the base portion 3 and the surface layer 7 by the synthetic resin binder 5, the base portion 3 and the surface layer 7 are pulled from each other. The structure is made robust by being united integrally for compression, impact, toughness and the like.

The base 3 itself has a raised bottom 3
Even if the thickness is reduced by being formed in b, the glass fiber, inorganic fiber such as carbon, metal fiber such as stainless steel, and further fiber such as synthetic resin are mixed therein even if the weight is reduced. , Base part 3 only by concrete
Even when the thickness is small as compared with the case where is formed, the tensile, compression, impact and toughness are increased, and the structure becomes robust.

Moreover, the raised bottom portion 3 provided below the base portion 3
b is an arc-shaped inclined portion 3b ₁ , 3b ₁ having a substantially arc-shaped cross section with a central portion that is most deeply concave and descends in the left-right direction;
Because it is formed in the arcuate inclined portion 3b _1, 3b draining slope portion 3b ₂ provided continuously to the outer end of the _1, 3b ₂ more becomes arched, impact, the force from particular above the load, such as arcuate The stress is dispersed along the inclined portions 3b ₁ , 3b ₁ and the draining slope portions 3b ₂ , 3b ₂ , thereby exhibiting high rigidity.

In addition, for example, as shown in FIG.
Since the plurality of drain holes 8 in the row are formed so as to substantially cross in the direction in which the lid body 2 is laid, the structurally robust thick portions 3c, 3c are located between the thick portions 3c, 3c. There is no inconvenience such that the thin portion to be broken withstands load, tension, impact, toughness and the like.
