Description

  The present invention relates to a side groove cover, for example, where the side groove cover is left without being covered with the side groove cover, or where there is a large amount of traffic or the width of the roadway is narrow, and it is not easy to rattle. It can be applied optimally as a culvert-type side gutter at construction sites where there are severe conditions.

  Conventionally, for example, the lid hanging portion provided above the opening-type side groove that opens the upper opening is not covered with the existing side groove lid, where it is left as it is, or there is a lot of traffic, the width of the roadway is In confined spaces, etc., simply placing the side groove cover on the lid hanging part provided above the side groove with the drainage hole opened in the longitudinal direction can cause a rattling sound. In many cases, a gutter-type side groove formed integrally with a top plate portion is formed above a side groove formed of concrete using a mold.

  And this culvert-type side gutter collects rainwater that flows down the road along the road gradient through the slit when it rains by providing a slit over the entire length in the longitudinal direction at the approximate center of the top surface. There were some that drained down into the drainage holes and drained (see Patent Document 1).

  By the way, when it is necessary to cover the lid after the fact when the lid is not covered on the lid opening of the upper opening of the gutter-type side groove already laid on the shoulder along the road, or the lid of the side groove The cover is already covered, but when there is a lot of traffic or the width of the roadway is narrow, a concrete body is placed in the lid hanging part at the construction site to form the lid. It was.

That is, in order to form a lid on the lid hanging portion at the construction site, a concrete formwork plate is horizontally installed in the lid hanging portion of the side groove, and the formwork plate is supported by a plurality of support members. After assembling to withstand the load, structural materials such as main bars and distribution bars are placed above the formwork plate, and then concrete is placed in the recesses of the lid hanging part to cure and solidify. In some cases, a side groove cover integral with the mold plate is formed (see, for example, Patent Document 2).
Utility model registration No. 3025382. JP-A-9-13486.

  However, the conventional side groove block described in Patent Document 1 is molded at a factory using a molding die. For molding, assembling the molding die or into a molding die for reinforcing bars as a structural material. It takes a lot of processes, and it takes a lot of processes, because it requires many steps, such as the placement of concrete in the mold, curing / solidification, mold release from the mold, and disassembly of the mold. It took time and the production cost was expensive.

  Moreover, in the side groove block of patent document 1, since the side groove block and the top | upper surface part were shape | molded integrally, weight was large and the conveyance and construction from a factory to a construction site were not easy.

  Moreover, in the gutter block described in Patent Document 1, a slit for collecting rainwater over the entire length in the longitudinal direction is provided in the approximate center of the top surface portion, so that a disabled person crosses this slit with a wheelchair.

  Moreover, when the rain water and sewage are flowing in the drain hole provided in the side groove at the time of construction, the conventional side groove cover described in Patent Document 2 needs to be stopped. Also, in order to mold the side groove lid at the construction site, it can withstand the weight of the formwork plate made of concrete to be installed on the side groove cover and the weight of the concrete cast on the top surface of the formwork plate. Because of the support structure, it is necessary to carry out support work to support the form plate by setting up multiple support members on the lower surface of the form plate, and it is necessary to remove the support member after forming the side groove lid It was to make. In addition, in order to prevent slipping, surface finishing work must be performed by brushing the surface finish of concrete cast in place on the upper surface of the formwork plate, which is often used for molding and production. Labor, time, and material costs were required, and production costs were expensive.

  In addition, the above-mentioned conventional side groove cover described in Patent Document 2 collects rainwater that flows down the road surface along a road gradient at the time of rain. Rainwater is collected through a gap formed between the lid and the inner wall of the side groove cover, and then drained into the drainage hole of the side groove to drain the water. I was not satisfied. In addition, the installation of the above-mentioned drainage basin between the ditches is whether the road width at the construction site, the road slope, the soil quality, whether drainage is good or bad, and whether the traffic volume is high or low. Due to the differences in the field conditions such as, the installation position, installation distance, etc. of the drainage basin provided between the side grooves were different, and the work efficiency at the time of construction was poor.

  The details of the present invention will be described below according to the best mode for carrying out the present invention with reference to the drawings.

  FIG. 1 is a longitudinal sectional view showing a laid state of a side groove cover according to the present invention, FIG. 2 is a plan view, FIG. 3 is a transverse sectional view showing the laid state, and FIG. FIG.

  The first embodiment is a side groove lid 1 formed on a lid hanging portion 4 provided on the upper side of the drainage hole 2 of the side groove 3 that opens the drainage hole 2 in the longitudinal direction I, and the lid hanging portion. 4, a discard frame plate 5 provided so as to be placed thereon, a concrete base portion 6 placed on the discard frame plate 5 at a desired thickness t in the lid hanging portion 4, and the concrete base portion 6 The upper surface 4a of the lid hooking portion 4 and a concrete surface layer lid portion 7 laid at substantially the same height h, and the concrete base portion 6 is reinforced with a reinforcing bar 8 inside, and the surface layer lid portion. 7, a slit 9 is provided in the longitudinal direction I, and a water collecting pipe 10 is provided at a lower portion of the slit 9 so as to penetrate the concrete base portion 6 so as to be cut to a desired length l.

  In the first embodiment shown in the figure, by using the discard frame plate 5 as a mold plate, concrete C is placed on the discard frame plate 5, and the concrete base portion 6 is cured and solidified. The side groove cover 1 in which the surface layer cover part 7 is integrated is formed. In addition, the use of the discarded frame plate 5 as shown in the drawing is merely an example, and the present invention is not limited thereto.

  In the illustrated first embodiment, the side groove cover 1 is formed to have a length L of 800 mm, a width W of 120 mm, and a thickness T of about 40 mm. The size of can be changed according to the length L 'and the width W' of the side groove 3 laid on the shoulder.

  The discard frame plate 5 is formed in advance in a substantially rectangular plane in a factory in advance, for example, with fiber reinforced cement. The discard frame plate 5 has a high bending strength and rigidity, has a size that occupies at least the lower surface portion of the surface layer lid portion 7, and is closely integrated with the concrete base portion 6. It becomes part of the rebar cover and prevents corrosion of the rebar and neutralization of the concrete, and makes it easy to join the concrete base 6.

  And in this Embodiment 1, by using the discard frame plate 5 as a mold plate, concrete C is placed on the discard frame plate 5 on the construction site, and it is cured and solidified to be the concrete base portion 6. And the surface lid portion 7 are integrally molded and used as a permanent mold without being disassembled or removed. However, the mold plate is used only for the discarded frame plate 5 shown in the figure. Rather, after the cast-in-place concrete C is cured and solidified, the concrete base portion 6 is united with the surface layer lid portion 7 and the side groove lid 1 is formed, it is disassembled and demolded. A plate can also be used.

  As a fiber suitable for the fiber reinforced cement, for example, glass fiber, carbon fiber, metal fiber, and synthetic fiber are used. In the first embodiment, for example, Portland cement is used as the cement, and a glass fiber having a fiber diameter of about 15 μm and a length of about 38 mm is focused on the Portland cement with a desired weight ratio. By mixing and kneading as described above, the discard frame plate 5 is formed.

  The mixing ratio of Portland cement, aggregate, water, and glass fiber is, for example, 48% by weight of Portland cement: 31% by weight of aggregate: 16% by weight of water: glass fiber (fiber diameter 15 μm, length 38 mm) 5% by weight.

  The surface lid portion 7 has a slight slope on the surface toward the slit 9 to facilitate water collection. Further, in order to prevent slipping, the surface of the surface lid portion 7 is subjected to surface processing such as brushing at a factory. In the first embodiment, three slits 9 provided in the surface lid portion 7 are formed in the longitudinal direction I as shown in FIG. Each of the slits 9 has an upper surface formed in a concave shape in a longitudinal section with a front end portion and a rear end portion in the longitudinal direction I positioned at high positions a and a, and a central portion in the longitudinal direction I at the lowest position b. When the rainwater rained on the road R enters the slit 9 by forming a substantially hemispherical concave surface portion 9b in the substantially central portion, the front end portion and the rear end in the longitudinal direction I located at the high positions a and a From the upper part to the lowermost part b of the slit 9 formed in a concave cross section, flows down the inclined surface 9a, 9a, and quickly and smoothly into the side groove 3 through the water collecting pipe 10 attached to the lower center of the slit 9. The water is collected and flows down.

  The substantially hemispherical concave surface portion 9b is formed in the substantially central portion of the lower surface of the slit 9 because rainwater collected by the slit 9 is accumulated by the concave surface portion 9b and clogged. This is to make it easy to introduce rainwater into the water collecting pipe 10 by forcibly discharging garbage, earth and sand by water pressure.

  The water collecting pipe 10 is formed of a synthetic resin pipe, and the water collecting pipe 10 penetrates the concrete base portion 6 at the lower part of the lowest position b in the longitudinal direction I of the slit 9 and the lower end is desired in the side groove 3. The water collecting pipe 10 is disposed in the concrete base portion 6 between the main bars 8 </ b> A backed at a desired pitch P in the longitudinal direction I.

  In the illustrated first embodiment, the main reinforcing bars 8A are arranged in such a manner that a total of six crossing in the longitudinal direction I intersects with one slit 9 in two at the front and rear at an equal pitch P of 125 mm. Reference numeral 8B denotes a reinforcing bar that crosses the main reinforcing bar 8A and arranges a desired number of bars in the longitudinal direction I. The distributing bar 8B is combined with the main reinforcing bar 8A as a structural material in the concrete base portion 6. It is strong against compression, tension, and twist by being backed.

  The first embodiment has the above-described configuration. For example, the water collecting hole is simply provided in the lid hooking portion 4 of the open side groove 3 or the existing side groove lid 1 having the slit is not covered, and the first embodiment is left as it is. The existing side gutter lid 1 is put on the lid portion 4 above the gutter 3 where the drainage hole 2 is simply opened in the longitudinal direction I. In order to form the side groove lid 1 of the first embodiment into the lid hanging portion 4 of the side groove 3 at a construction site where the rattling sound is severe, the fiber reinforced cement is first formed on the lid hanging portion 4 of the side groove 3. A discard frame plate 5 as a mold plate is placed.

  At this time, the size of the scraping frame plate 5 can be changed according to the size of the side groove lid 1 to be molded according to the length L 'and the width W' of the side groove 3 laid on the road shoulder. .

  Next, at the construction site, a total of six main bars 8A are crossed in the longitudinal direction I at a regular pitch P of 125 mm as reinforcing bars on the scraped frame plate 5, and then the main bars 8A are crossed in the longitudinal direction. The reinforcing bars 8 are assembled by arranging a desired number of the reinforcing bars 8B in the direction I.

  Then, a concrete base portion 6 having a desired thickness t is formed by placing concrete C on the scraping frame plate 5 in the lid hanging portion 4.

  At this time, as shown in FIG. 1 and FIG. 2 provided at equal pitch P across the longitudinal direction I of the concrete base portion 6, the odd number (1, 3, 5th) and even number of the six main bars 8A in total. Three socket pipes 11 are arranged in the middle part between (second, fourth, sixth) so that the lower end penetrates below the discard frame plate 5.

  Then, by placing the concrete surface layer lid portion 7 at an appropriate time while the concrete C placed to form the concrete base portion 6 is not yet solidified, the upper surface of the surface layer lid portion 7 is covered with the lid portion. 4 is laid at substantially the same height h as the upper surface 4a.

  At this time, the installation position of the surface lid portion 7 with respect to the concrete base portion 6 is, for example, that the width of the road R is narrow, the rainfall amount varies depending on the width, the road gradient varies slowly, the soil drainage is good, etc. In consideration of the on-site situation such as bad, the concrete base 6 is placed at a desired position and at a desired distance. Moreover, the concrete base 6 is subjected to a brush drawing process that harmonizes with the brush drawing processed at the factory on the surface of the surface lid 7 while the placed concrete C is not yet cured or solidified. Thereby, the surface processing in the construction site of the concrete base part 6 for the part performed to the surface layer cover part 7 can be reduced.

  At this time, the water collecting pipe 10 as a synthetic resin pipe disposed in the lowest position b of the three slits 9 provided in the longitudinal direction I of the surface layer lid portion 7 is cut to a desired length l, and a reinforcing bar such as the main reinforcing bar 8A. Of the total six main bars 8A provided at the equal pitch P on the concrete base 6 in which 8 bars are arranged, the odd-numbered (1, 3, 5th) and even-numbered (2, 4, 6) 8), and the water collecting pipe 10 is inserted into the three socket pipes 11 penetrating the concrete base portion 6 and facing the lower end in the side groove 3 so that the main bar 8A is inserted. Since it can be connected easily and reliably without changing the pitch P, arrangement order, number, etc. of the reinforcing bars 8 as structural materials, etc., connection work and construction between the water collecting pipe 10 and the socket pipe 11 can be performed easily and conveniently. It is.

  And the concrete base part 6 cast | casted in the construction site as mentioned above by the concrete C of the concrete base part 6 hardening | curing, and the concrete surface layer cover part 7 previously shape | molded in the factory. For example, the gutter lid 1 is formed by integrating in accordance with the field conditions such as whether the rainfall amount is different, the slope of the road R is different, or whether the soil is drained or not.

  In this way, the side groove cover 1 of the first embodiment is against the concrete base part 6 placed at a desired thickness t on the disposal frame plate 5 installed on the cover hanging part 4 of the side groove 3 at the construction site. Since the concrete surface layer lid portion 7 formed in advance in the factory is integrated and molded, the surface layer lid portion 7 that is lightweight and easy to handle is transported to the construction site. As in the case of a conventional side groove cover, the side groove cover 1 can be formed without having to perform a water stop work when rainwater or sewage flows in a drain hole provided in the side groove during molding at a construction site. Further, in forming the side groove cover 2, as in Patent Document 2, it is not necessary to stand a support member for supporting the form plate made of concrete erected on the cover portion of the side groove on the lower surface of the form plate. Since the lid 1 can be molded, the support work for supporting the formwork plate and the removal of the support member after the side groove lid 1 are molded become unnecessary, and the molding and production do not take much labor and time and are efficient. The material cost and production cost can be reduced.

  Moreover, the concrete base portion 6 and the surface layer lid portion 7 are integrated, and the structure becomes robust. In addition, the surface of the surface layer lid portion 7 is brushed in accordance with the brush drawing process processed in the factory. Since the process only needs to be formed, the surface finish can be easily performed.

  Further, the surface layer lid portion 7 of the side groove lid 1 of the first embodiment has a longitudinal section concave shape in which the front end portion and the rear end portion in the longitudinal direction I are positioned at the high positions a and a and the central portion in the longitudinal direction I is the lowest position b. Are formed in the longitudinal direction I, and a water collecting pipe 10 having a desired length l is connected to a socket pipe 11 provided so as to penetrate the concrete base 6 at a lower portion of the slit 9. Therefore, the rainwater that flows down the road R along the road gradient when it rains is from the high position a, a where the upper surface of the slit 9 is located at the front end portion and the rear end portion in the longitudinal direction I to the central portion in the longitudinal direction I. Water is collected by flowing down the inclined surfaces 9a, 9a to the lowest position b, and flows down into the side groove 3 through the water collection pipe 10 and the socket pipe 11 located at the lower part of the lowest position b of the slit 9. Through the drainage.

  At this time, since the substantially hemispherical concave surface portion 9b is formed in the substantially central portion of the lower surface of the slit 9, the rainwater collected by the slit 9 as described above is diffused by the concave surface portion 9b. Garbage, earth and sand, etc., accumulated in the slit 9 and clogged are forcibly discharged together with rainwater by water pressure, and the clogging is cleared and easily introduced into the water collecting pipe 10.

  Accordingly, the side groove cover 1 of the first embodiment collects water every desired distance in order for the conventional side groove cover described in Patent Document 2 to collect rainwater that flows down the road R along the road gradient during rain. Rainwater is collected through a gap formed between the side groove cover and the inner wall of the side groove cover hook part (not shown) between the side grooves, and flows down into the drain hole of the side groove. Unlike drainage, the desired position depends on the site conditions, such as the amount of rainfall is large or small, the slope of the road R is gradually different, the drainage is good, or the soil quality is poor. Alternatively, it is possible to collect rainwater efficiently by providing slits 9 for collecting rainwater or the like at a desired distance.

  Further, the side groove lid 1 of the first embodiment is provided with three slits 9 formed in a concave shape in the longitudinal section in the longitudinal direction I of the surface layer lid portion 7, so that the top surface portion formed integrally with the side groove block Unlike the culvert-type side groove block described in Patent Document 1 in which a slit is formed in the longitudinal direction in the approximate center of the slit, when the disabled person crosses the surface lid 7 with the wheelchair, the slit 9 is advanced by the wheelchair by itself. It does not cause obstacles to barrier-free, such as not receiving a large impact, and is unsightly in appearance and does not appear to be unsightly. Moreover, since the side groove cover 1 is not molded at the stage where it is formed at the factory in the lid hanging portion 4 of the side groove 3, the weight of the side groove 3 itself is reduced, and transportation and construction from the factory to the construction site are easy. Can be done. Furthermore, since the slit 9 of the first embodiment is formed in a concave shape in the longitudinal section, cleaning can be easily performed from the outside.

  As described above, the side groove lid 1 of the first embodiment is formed on the concrete base portion 6 on which the concrete C is placed at a desired thickness t on the disposal frame plate 5 installed on the lid hanging portion 4 of the side groove 3 at the construction site. On the other hand, since it is integrally formed by placing a concrete cover lid portion 7 formed in a substantially rectangular shape in advance at the factory, it differs depending on the length L ′ and width W ′ of the side groove 3. It is within the scope of the present invention to adjust the placement amount of the concrete C of the concrete base portion 6 in accordance with the height h of the lid hanging portion 4 associated with the size of the side groove 3.

  In the first embodiment shown in the figure, the surface layer lid portion 7 is placed at a desired position at a desired distance on a portion of the concrete base portion 6 that is placed on the lid hanging portion 4 of the side groove 3 with respect to the scraping frame plate 5. However, it is possible to freely change the number, arrangement, and increase / decrease of the surface layer lid portion 7 installed in the lid hanging portion 4 of the side groove 3 addressed to one.

  Furthermore, the number of slits 9 provided in the front cover 7, the order of arrangement, and the installation length can be freely changed.

  Moreover, in the said description, although the discard frame plate 5 united with the concrete base part 6 was used as a mold board, the form plate of this invention is not restricted to this, For example, concrete C of the concrete base part 6 The concrete base 6 is integrated with the surface layer lid 7 to form the side groove lid 1 after being molded and cured and solidified, and then disassembled and released from the side groove lid 1. It is a range.

  The present invention enables efficient production in a short time without much labor at the construction site and efficient surface finishing work, and a slit for collecting water at a desired position corresponding to the site situation. It has excellent water collection efficiency and is suitable for barrier-free measures such as a person with a disability crossing with a wheelchair, and it has no appearance and is well-finished.
