Description

The present invention relates to a constituent member including a drainage structure portion for draining rainwater from a road or the like and a boundary structure portion for dividing a section such as a sidewalk and a roadway, and a method for manufacturing a structure using the constituent member.

Conventionally, a road surface structure has been adopted in which a curb or the like that separates the roadway and the sidewalk is arranged. For example, the curb block of Patent Document 1 is integrally formed of concrete as a whole, and prevents vehicles and the like from accidentally invading the sidewalk side from the roadway. Further, conventionally, gutters have been buried in the shoulders and the like in order to drain rainwater. This gutter is integrally formed of concrete as a whole, and has a substantially U-shape with an opening on the upper end side. On the shoulder of the road, curb blocks are arranged side by side along the gutter, and the arrangement makes it possible to collect rainwater from the road surface while separating the roadway and the sidewalk.

By the way, since the gutter is entirely made of concrete, heavy machinery or the like was used when installing the gutter. Then, after arranging the gutters, the curb blocks are lined up, but since the curb blocks are also made of concrete, it is necessary to use heavy machinery again. Therefore, there is a problem that the installation work becomes complicated and the cost such as heavy machinery cost and labor cost increases.

100 Drainage structure 140 Drainage channel 200 Boundary structure 300 Components

Hereinafter, embodiments of the present invention will be described with reference to FIGS. 1 and 2. It should be noted that the shape of each figure referred to in the following description is a conceptual diagram or a schematic diagram for explaining suitable shape dimensions, and the dimensional ratio and the like do not always match the actual dimensional ratio. That is, the invention of the present application is not limited to the dimensional ratio in the drawings. As shown in FIG. 2, "upper" as used in the present specification means a direction toward the upper side in the vertical direction with respect to the component member 300 installed on the horizontal plane, and "lower" means. , The direction toward the lower side in the vertical direction.

First, FIG. 1 shows the constituent member 300 of the present invention, FIG. 1A is a side view of the constituent member 300, FIG. 1B is a plan view of the constituent member 300, and FIG. 1C is a plan view of the constituent member 300. A front view of the constituent member 300 and FIG. 1 (d) are cross-sectional views taken along the line AA of the constituent member 300.

As shown in FIG. 1, the constituent member 300 includes a drainage structure portion 100 formed of a plate member and a boundary structure portion 200 attached adjacent to the drainage structure portion 100 and formed of a plate member. There is. Specifically, the drainage structure portion 100 is composed of a bottom wall 110, a side wall 120 and a side wall 130 that rise upward from both ends of the bottom wall 110, and has a substantially U-shaped cross section so as to form a drainage channel 140 inside. It is formed in a shape. Further, the boundary structure portion 200 includes an inner side wall portion 210 continuous with the upper end of the side wall 130 of the drainage structure portion 100, an upper wall portion 220 extending horizontally from the inner side wall portion 210, and a downward portion from the upper wall portion 220. It is composed of an extending outer wall portion 230 and a bottom wall portion 240 extending from the lower end of the outer wall portion 230 to the inner side wall portion 210, and a cavity is formed inside. As will be described later, this cavity is a catchment channel 250 that collects fluid such as rainwater.

Further, the outflow portion 211 is formed on the inner side wall portion 210, and the inflow portion 231 is formed on the outer wall portion 230. The inflow portion 231 and the outflow portion 211 are elongated through holes extending in the horizontal direction, and the width of the inflow portion 231 (in other words, the length in the horizontal direction) is larger than the width of the outflow portion 211. There is. Further, since the outflow section 211 and the inflow section 231 communicate with the catchment channel 250 and the outflow section 211 faces the drainage channel 140, a fluid such as rainwater flowing into the inflow section 231 will be described later. Will flow out to the outflow section 211 through the catchment channel 250, and will be drained to the drainage channel 140.

The shape of the outflow portion 211 and the inflow portion 231 is not limited to a long through hole extending in the horizontal direction, that is, an elongated hole, and may be any shape. Further, a clogging prevention member such as a mesh may be attached so that the outflow portion 211 and the inflow portion 231 are not clogged with dust or the like. Further, the inflow portion 231 of the boundary structure portion 200 is arranged at a position higher than the outflow portion 211, but is not limited to this, and the inflow portion 231 and the outflow portion 211 are arranged so as to be in the same plane. May be good.

Further, since the boundary structure portion 200 is attached to the outside of the side wall 130 of the drainage structure portion 100, the boundary structure portion 200 does not project to the upper end side of the drainage channel 140 of the drainage structure portion 100. Therefore, since the opening area on the upper end side of the drainage channel 140 is not narrowed, the water collection efficiency is not lowered when rainwater or the like is collected from the upper end side of the drainage channel 140. Further, as will be described later, a lid member such as grating may be placed on the upper end side of the drainage channel 140, but since the boundary structure portion 200 does not project to the upper end side of the drainage channel 140, the boundary structure portion The 200 does not interfere with the attachment / detachment of the lid member.

The constituent member 300 is formed by bending a single metal plate so as to have the shape shown in FIG. 1, but the present invention is not limited to this, and the plate members constituting each wall portion are welded to each other or the like. It may be connected with and assembled into the shape shown in FIG. Further, the constituent member 300 is integrally formed with the drainage structure portion 100 and the boundary structure portion 200 from one metal plate, but the present invention is not limited to this, and the drainage structure portion 100 and the boundary structure portion 200 are combined with each other. May be formed separately, and the upper end of the side wall 130 of the drainage structure portion 100 and the lower end of the inner side wall portion 210 of the boundary structure portion 200 may be connected to each other.

Next, with reference to FIG. 2, a method of constructing the constituent member 300 of the present invention, in other words, a method of manufacturing a structure having drainage and boundary functions using the constituent member 300 will be described. 2 (a) to 2 (c) are side views showing the manufacturing process of the structure.

First, as shown in FIG. 2A, the two outer formwork 400s are installed at a predetermined distance from each other on the desired installation surface G on which the structure is to be installed. The outer formwork 400 is a mere plate member conventionally known, and is installed on the installation surface G by using an arbitrary fixing member such as a bolt. Then, as shown in FIG. 2A, concrete C1 is poured between the outer formwork 400. In this state, the concrete C1 is not solidified and is in a liquid state. As will be described later, the predetermined spacing between the outer formwork 400s can be arbitrarily determined as long as the spacing allows the constituent members 300 to be installed between the outer formwork 400s.

Next, as shown in FIG. 2B, the constituent member 300 is submerged from above the concrete C1 to fix the position of the constituent member 300. The position of the constituent member 300 may be fixed by any existing method, and the constituent member 300 is fixed by using a jig or the like that presses the constituent member 300 from above so that the constituent member 300 does not come up. Then, as shown in FIG. 2B, when the constituent member 300 is submerged, the concrete C1 is extruded and filled between the outer formwork 400 and the side wall 120. Similarly, concrete C1 is extruded and filled between the outer formwork 400 and the side wall 130. If the amount of concrete C1 to be filled between the outer formwork 400 and the side wall 120 or between the outer formwork 400 and the side wall 130 is insufficient, concrete C1 may be additionally poured and filled between them. ..

Then, if the concrete C1 is solidified in the state shown in FIG. 2B, the concrete C1 is fixed to the side wall 120 and integrated, and the concrete C1 and the side wall 120 form the side wall 510 of the structure 500. Similarly, the concrete C1 is fixed to and integrated with the bottom wall 110, and the concrete C1 and the bottom wall 110 form the bottom wall 520 of the structure 500. Similarly, the concrete C1 is fixed to the side wall 130 and integrated, and the concrete C1 and the side wall 130 form the side wall 530 of the structure 500. In this way, the constituent member 300 is used as an inner formwork forming the inner surface side of the structure 500, and the constituent member 300 and the concrete C1 around the constituent member 300 are integrated to manufacture the structure 500. ..

Next, as shown in FIG. 2C, after removing the outer formwork 400, asphalt or the like is poured around the structure 500 to form the road surface R1 and the road surface R2. Specifically, a road surface material such as asphalt is poured around the side wall 510 until the upper end of the side wall 510 of the structure 500 is covered to form the road surface R1. Similarly, a road surface material such as asphalt is poured around the side wall 530 until the upper end of the side wall 530 of the structure 500 is covered to form the road surface R2. A boundary structure portion 200 is located between the road surface R1 and the road surface R2, and the boundary structure portion 200 separates the road surface R1 and the road surface R2. The road surface R1 and the road surface R2 can be arbitrary sections such as a roadway and a sidewalk, respectively.

A lid member F1 is attached above the drainage channel 140. Specifically, one end of the lid member F1 is placed on the upper end of the side wall 510, and the other end of the lid member F1 is placed on the substantially L-shaped attachment F3 attached to the side wall 130. The surface of the road surface R1, the surface of the lid member F1, and the surface of the road surface R2 are all on the same surface. Further, the lid member F1 may be any member such as a grid-shaped grating or a plate-shaped lid member provided with water passage holes, and any member can cover the opening of the drainage channel 140. It may be in shape.

Then, as shown in FIG. 2C, the fluid W1 such as rainwater flowing from the surface of the road surface R1 is drained to the drainage channel 140 of the structure 500 via the lid member F1. Further, the fluid W2 flowing from the surface of the road surface R2 is collected from the inflow portion 231 of the boundary structure portion 200 to the catchment channel 250 of the boundary structure portion 200, and is collected from the catchment channel 250 to the drainage channel 140 via the outflow portion 211. It is drained to. Therefore, the structure 500 is provided with a drainage function by the drainage structure portion 100 and a boundary function by the boundary structure portion 200.

As described above, the constituent member 300 of the present invention includes the drainage structure portion 100 formed of the plate member and the boundary structure portion 200 formed of the plate member and having a hollow inside, so that the total weight thereof is increased. Lighter than conventional technology and very easy to handle. Further, since the constituent member 300 includes the drainage structure portion 100 and the boundary structure portion 200, it is possible to save the trouble of individually attaching the gutter and the curb as in the conventional case.

Further, since the drainage structure portion 100 is formed of a plate member, it is easy to respond to a shape change such as deepening the drainage channel or widening the width of the drainage channel by making a change such as lengthening the plate member. You can do it.

Further, in the constituent member 300 of the present invention, the cavity in the boundary structure portion 200 is a catchment channel 250, and the inflow section 231 and the catchment channel for flowing the fluid from the outside of the boundary structure portion 200 into the catchment channel 250. Since the outflow portion 211 for flowing out the fluid from the 250 to the drainage channel 140 is provided, as shown in FIG. 2, the fluidity W2 collected from the road surface R2 is sent to the drainage channel 140 via the drainage channel 250. It can be drained effectively. Further, even if a large amount of fluid W2 flows in, a large amount of fluid W2 can be collected in the hollow catchment channel 250, so that the fluid W2 can be prevented from accumulating on the road surface R2. You can do it.

Further, since the constituent member 300 of the present invention is made of a steel plate member, the plate member can be easily processed and the constituent member 300 can be easily manufactured. Further, if it is a steel plate member, it has high strength and can withstand practical use sufficiently, and since it is a generally distributed material, it is easy to handle. The plate member is not limited to steel, and any material other than steel, resin, or the like can be adopted depending on the place where the constituent member 300 is installed.

Further, according to the method for manufacturing the structure 500 using the constituent member 300 of the present invention, concrete C1 is filled between the constituent member 300 used as the inner formwork and the outer formwork 400 to fill the constituent member 300. If the concrete C1 and the concrete C1 are integrated, the structure 500 including the drainage structure portion and the boundary structure portion can be easily manufactured.

In particular, in the prior art, when manufacturing a gutter which is a drainage structure part, a special formwork is required because the gutter is integrally molded with concrete. Further, on the inner surface of the gutter, a drainage channel portion, a place where a lid member is placed, etc. must be formed, and the shape of the inner surface becomes complicated, so that a dedicated expensive inner formwork is required. .. On the other hand, since it is only necessary to form a flat wall surface on the outside of the gutter, a simple plate-shaped inexpensive outer formwork is sufficient. For the above reasons, in the prior art, it was common to manufacture a gutter in advance at a manufacturing factory that owns a dedicated and expensive inner formwork, and then transport the gutter to the site for installation. In other words, the gutters that had been manufactured in advance at the factory or the like had to be transported to the site and installed by heavy machinery or the like.

However, according to the method for manufacturing the structure 500 of the present invention, since the constituent member 300 is used as the inner formwork, only the outer formwork 400 having a simple structure needs to be prepared at the site. Then, if concrete C1 is filled between the constituent member 300 and the outer formwork 400 and the constituent member 300 and the concrete C1 are integrated, a structure having a drainage structure portion and a boundary structure portion can be easily provided at the site. The thing 500 can be manufactured. Further, since the constituent member 300, which is lighter than the conventional gutter, can be used, the work in the field becomes very easy.

Further, according to the method for manufacturing the structure 500 of the present invention, the strength of the wall portion (side wall 510, bottom wall 520, side wall 530) of the structure 500 is thicker than that of the plate member of the drainage structure portion 100. Since it is sufficiently secured by the above, the plate thickness of the plate member of the drainage structure portion 100 can be reduced, the weight of the constituent member 300 is further reduced, and the work in the field is further facilitated. Further, even if the drainage structure 100 is damaged due to aged deterioration (for example, rust), the concrete C1 integrated around the drainage structure 100 continues to function as a drainage channel, so that the drainage function can be achieved. It will not be lost. If you want to prevent damage to the drainage structure 100, you can use a material that does not easily rust (for example, aluminum alloy plating) or apply an anticorrosive agent to the surface of the drainage structure 100. good.

Further, in the prior art, when the curb is arranged along the gutter, after the gutter is arranged, the curb prepared separately is fixed by using an adhesive such as mortar. However, according to the method for manufacturing the structure 500 of the present invention, as shown in FIG. 2B, between the outer wall portion 230 of the boundary structure portion 200 provided in the constituent member 300 and the outer formwork 400. Also filled with concrete C1 to integrate the boundary structure portion 200 and concrete C1. Therefore, it is not necessary to bother to fix the curb afterwards as in the conventional case, and the boundary structure portion 200 is integrated with the structure 500 and firmly fixed at the time of manufacturing the structure 500. Further, since the boundary structure portion 200 is integrated with the concrete C1 to increase its strength, even if the boundary structure portion 200 is made of a plate member and the inside is hollow, the boundary structure portion 200 has sufficient strength to withstand an external force.

In addition, in FIG. 2B, concrete C1 was also filled between the outer wall portion 230 of the boundary structure portion 200 and the outer formwork 400 to integrate the boundary structure portion 200 and the concrete C1. The concrete C1 may be filled up to the bottom wall portion 240 of the boundary structure portion 200, and the bottom wall portion 240 and the concrete C1 may be brought into close contact with each other and integrated. That is, if a part of the boundary structure portion 200 is in close contact with the concrete C1 and integrated, the boundary structure portion 200 is integrated with the structure 500 and firmly fixed at the time of manufacturing the structure 500, and has sufficient strength. Be prepared.

Further, in FIGS. 1 and 2, since the width of the inflow portion 231 is larger than the width of the outflow portion 211, the inflow portion 231 facing the outer road surface R2 is a fluid together with small dust such as pebbles. W2 can flow into the catchment channel 250. Therefore, it is possible to prevent the inflow portion 231 from being clogged. Since it is difficult for small dust such as pebbles to pass through the outflow portion 211 having a width smaller than that of the inflow portion 231, it is possible to prevent the small dust such as pebbles from staying in the catchment channel 250 and being discharged to the drainage channel 140. The dust collected in the catchment channel 250 can be removed from an inspection window (not shown) provided in a part of the boundary structure portion 200.

Further, in FIGS. 1 and 2, the inflow portion 231 was a long hole extending in the horizontal direction, but the shape also includes a long hole extending in the vertical direction, that is, the inflow portion 231 is a through hole having a substantially T shape in front view. May be good. When the inflow portion 231 has a substantially T-shape in front view, the fluid W2 flowing on the surface of the road surface R2 extends in the vertical direction even if the surface of the road surface R2 shown in FIG. Water is collected from the long hole.

In FIG. 2C, the lid member F1 and the road surface R2 are configured to be on the same plane, but the configuration is not limited to this, and the position of the lid member F1 is higher than the road surface R2. The lid member F1 may be configured to be flush with the upper wall portion 220 of the boundary structure portion 200. Further, in FIG. 2C, the lid member F1 is installed above the drainage channel 140, but the lid member F1 is not an indispensable constituent requirement, and the lid member F1 may be removed.

Further, in FIGS. 1 and 2, the bottom wall 110 of the drainage structure portion 100 is a flat surface, but the shape is not limited to this, and the shape of the bottom wall 110 may be any shape. For example, if the center of the bottom wall 110 has a substantially V-shape that is bent downward, air can easily escape when the concrete C1 filled below the bottom wall 110 solidifies. Further, if a rod-shaped projecting portion is provided on the outer surface of the drainage structure portion 100, it will be more firmly fixed to the concrete C1. Further, if the plate member of the drainage structure portion 100 is provided with a through hole, air can easily escape from the through hole when the concrete C1 around the drainage structure portion 100 is solidified. Further, if a sewer pipe or the like is penetrated and connected to a through hole provided in the plate member of the drainage structure portion 100, sewage or the like can be drained from the sewer pipe or the like to the drainage structure portion 100. Further, if the concrete C1 filled around the drainage structure portion 100 or the buried material 640 described later is permeable, a fluid such as rainwater in the drainage structure portion 100 can be used as a plate member of the drainage structure portion 100. It is possible to drain water to the outside of the drainage structure portion 100 through the through hole provided in.

<Modification 1>
Next, with reference to FIG. 3, a method of constructing the constituent member 300 according to the modified example 1 of the present invention, in other words, a manufacturing method according to the modified example 1 of a structure having drainage and boundary functions using the constituent member 300. Will be explained. 3 (a) to 3 (c) are side views showing the manufacturing process of the structure. Further, the manufacturing method according to the modified example 1 shown in FIG. 3 differs from the manufacturing method shown in FIG. 2 in the fixing method of the constituent member 300 and the filling method of the concrete C1, but they are common in other points. Detailed explanation of common parts will be omitted.

First, as shown in FIG. 3A, the two outer formwork 400s are installed at a predetermined distance from each other on the desired installation surface G on which the structure is to be installed. Next, the constituent member 300 is fixed in the space between the outer formwork 400 in a state of being floated from the installation surface G. Specifically, the fixing member 410 is attached between the outer formwork 400 and the side wall 120, and the fixing member 410 is attached between the outer formwork 400 and the side wall 130 to fix the constituent member 300.

Then, a foundation portion 620 for installing the constituent member 300 is formed on the bottom surface 610 of the buried hole 600. The foundation portion 620 may be any one such as crushed stone. Further, the foundation portion 620 is not an indispensable constituent requirement, and the constituent member 300 may be directly installed on the bottom surface 610 of the buried hole 600 without providing the foundation portion 620.

Next, as shown in FIG. 4B, the component member 300 is installed on the foundation portion 620. Then, the space between the side wall 120 of the constituent member 300 and the inner surface 630 of the buried hole 600 is filled with the buried material 640. Similarly, the space between the side wall 130 of the constituent member 300 and the inner surface 630 of the buried hole 600 is replenished with the buried material 640. The buried material 640 may be any material such as crushed stone and soil generated when the buried hole 600 is mined. The periphery of the bottom wall 110 is supported by the foundation portion 620 to improve the strength, and the bottom wall 110 and the foundation portion 620 form the bottom wall 520A. Similarly, the periphery of the side wall 120 is supported by the buried material 640 to improve the strength, and the side wall 120 and the buried material 640 form the side wall 510A. Further, the periphery of the side wall 130 is supported by the buried material 640 to improve the strength, and the side wall 130 and the buried material 640 form the side wall 530A. In this way, the constituent member 300 is reinforced by the foundation portion 620 and the buried material 640 around the constituent member 300, and the structure 500 is manufactured.
