Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a structure of a water collecting basin which is buried in a road or the like in order to collect and discharge rainwater or the like from a gutter or a buried pipe.

[0002]

2. Description of the Related Art A plurality of gutters installed on the side of a road,
A collecting basin is used to connect underground pipes and to collect and discharge rainwater and drainage flowing through these pipes. Some water collecting basins have water collecting gutters connected to two or three sides and drain pipes connected to the other two or one side. May be provided to change the.

In such a water collecting basin, the burying levels and positions of the gutters and the burying pipes to be connected are various, and the caliber and shape of the gutters and the burying pipes are often different for each water collecting basin. Conventionally, the mold was assembled on-site, and concrete was poured into it to manufacture.

In order to manufacture a concrete basin extending vertically like a water collecting basin at the site, in addition to an outer form forming the outer surface of the water collecting basin, an inner surface forming the inner surface of the water collecting basin is formed. The formwork must also be manufactured on site to assemble the entire formwork.
In order to manufacture the inner formwork, it is necessary to accurately cut and assemble formwork materials such as a control panel, which is a very troublesome work. Further, since the upper part of the water collecting basin is exposed to the road surface, it is necessary to finish the upper part of the water collecting basin with a metal iron after manufacturing the main body of the water collecting basin. There is also a problem that the control panel used on site is wasted because it is discarded.

[0005]

Therefore, it is considered that the water collecting basin is prefabricated in a factory and installed after being brought into the field. By prefabricating a water collecting basin of a predetermined size at the factory,
Since the mold can be manufactured using a durable mold, the mold is not wasted, and the work of assembling the mold on site can be omitted. Furthermore, if it is shipped as a factory prefabricated product, steam curing can be performed using a durable formwork, so the upper part of the water collecting basin exposed on the road surface can also be shipped in a finished state, which saves on-site labor.

Even in a water collecting basin prefabricated in a factory, it is desirable to prepare a box opener in accordance with the level of a gutter or a buried pipe connected to the side wall of the basin in order to reduce the number of steps in the field. . Therefore, depending on the site, it is necessary to form the box open up to the upper part of the water collecting basin, or it is necessary to form the box open at various positions other than the center of the side wall. Therefore, in the conventional factory prefabricated product, the hanging insert is embedded in the side wall, but when the water collecting basin is factory prefabricated, the insert may be embedded because it may overlap with the above box removal. The position cannot be determined. For this reason, when prefabricating a factory using a durable mold, it is difficult to embed the insert, and it is not possible to adopt a method of installing a hanging bolt or the like on the insert to carry and laterally hold it. Therefore, it is troublesome to carry the water collecting basin in the field or in the factory.

[0007] Further, since the order is received and the manufacturing is started in the factory after the level of the gutter and the piping on the site is finally determined, it is not possible to secure a sufficient curing period for the prefabricated water collecting basin. is there. In such cases,
Even if the insert is buried, sufficient adhesive strength cannot be ensured, and it is difficult to adopt the same transporting process using the insert and the work process on site as in the conventional case.

Therefore, in the present invention, by making it easy to carry the factory prefabricated water collecting cell having many advantages as described above, a water collecting cell that can be easily provided for on-site construction is provided. It is intended to be provided. It is also an object of the present invention to provide a water collecting basin capable of reliably and easily providing a hanging point for such a concrete product which is likely to have a short curing period. It is also an object to provide a method suitable for carrying such a water collecting basin at a site or a factory.

[0009]

[Means for Solving the Problems] Since it is necessary to prepare box openers at various places on the side wall of the water collecting basin depending on the site as described above, when manufacturing using a durable mold in a factory. It is difficult to embed the insert at a fixed position on the side wall. Therefore, in a water collecting basin having a substantially cylindrical main body having a substantially quadrangular cross section according to the present invention, at least two corners arranged diagonally among the four corners at the top of the main body. , The insert that can be used when suspending the main body is embedded facing upward. A substantially rectangular opening is opened in the upper part of the main body, but a place where the insert is embedded can be secured around the edge of this opening. And since the box is not formed even at the corner of the water collecting basin, if you insert the insert facing up in any of these four corners, you can set the insert along the corner of the main body Depth can be secured. Therefore, even in a water collecting basin that is shipped without a sufficient curing period, it is possible to previously bury an insert having a length that can exhibit an adhesive strength sufficient to withstand a suspension load. Furthermore, if the inserts are embedded in at least two corners of the four corners that are diagonally aligned, the water collecting basin can be hung in a well-balanced manner using these inserts, so stable transport and horizontal holding are possible. Installation on site is also easy.

As described above, if the inserts are buried in any of the four corners of the upper part of the water collecting basin, the inserts can be buried in a predetermined place at the time of manufacturing in the factory, and the curing period is not sufficient. Even in the case, sufficient pulling strength can be secured for the insert. Therefore, it is possible to carry from inside the factory by using the insert buried in the manufacturing stage of the factory, to carry, to transport to the site, and to carry out for construction at the site. For this reason, it is possible to save labor in the field, eliminate the waste, and solve the problem of carrying around, which has been a bottleneck in adopting a factory-produced water collecting basin that is aesthetically pleasing. Therefore, the adoption of the water collecting basin manufactured at the factory can be promoted, and the labor of the workers on the site can be reduced and the construction period can be shortened.

Further, in a water collecting basin which is made of an iron plate or has a cutout for receiving the lid of the grating on the upper part of the main body, the insert is embedded in the cutout facing upward. Is desirable. This is because, after installing the water collecting basin using the insert, the insert can be hidden by attaching a lid such as a grating to the notch. Therefore, it is possible to omit the finishing work of filling the mortar in the insert after the construction on site is completed. It is also possible to use this hanging insert for fixing such as grating.

Further, in the water collecting basin in which the metal for receiving the lid is buried in the notch, the inserts are attached to at least two corners of the four corners of the metal so as to face upward. That is also effective. This is because the adhesive strength of the insert can be increased by the adhesive force between the metal for receiving the lid and the main body of the water collecting basin. Especially when burying a metal for receiving the lid in the water collecting basin using an anchor for burying,
A large adhesion area can be secured between the lid receiving metal object and the main body. Therefore, if a pre-welded insert is embedded in the corner of the metal object for receiving the lid, a sufficient suspension load can be expected for the insert even if a sufficient curing period cannot be secured, and a stable and stable operation can be expected. It is possible to carry around easily.

In this way, if a water collecting basin with inserts embedded in any of the four corners of the upper part of the main body is used, a hanging metal fitting is first installed on this insert, and the hanging metal fitting is used to hang the water collecting basin. The main body can be suspended. Therefore, the water collecting basin can be carried in a stable and reliable manner not only in the factory but also in the warehouse, during transportation, and during construction on site.

[0014]

Embodiments of the present invention will be described below with reference to the drawings.

FIG. 1 shows a water collecting basin 10 according to an embodiment of the present invention. The water collecting basin 10 of this example has a substantially rectangular parallelepiped shape as a whole, and includes a main body 11 having a quadrangular cross section and extending in the vertical direction. Out of the side walls 12 to 15 of the main body 11, on three side walls 12, 13, and 14, the box-opening 16, 17, 18 which is suitable for the buried pipe 1, the side grooves 2 and 3 connected to the water collecting basin 10 at the site, respectively. Is formed in advance.

A substantially square opening 20 is formed above the main body 11 and the grating lid 5 can be attached to the opening 20. A notch 21 for receiving the grating lid 5 is provided inside the edge of the opening 20, and an angle 22 for receiving the lid is embedded in the notch 21. Then, inserts 30 facing upward are embedded in each of the four corners of the angle 22. Therefore, the water collecting basin 10 of the present example can be easily lifted by attaching the hanging bolts to the insert 30, and can be easily transported or transported in factories, sites and the like.

The water collecting basin 10 of this example is manufactured at a factory so that the water collecting basin can be easily installed by a skilled worker without the trouble of placing a formwork and placing concrete on site.
It is a type that is carried into the site and then buried. Further, in order to avoid the work of making holes in the field, when the water collecting basin 10 is manufactured in a factory, it is formed in advance at a predetermined position on the side wall by punching out a box. These box openers 16 to 18 are formed into shapes that match the shapes of the buried pipes and gutters that are connected at the site, and the heights of the box openers are also matched to the level of the pipes and gutters that are connected. It has been adjusted to. In this way, it is necessary to match the position and shape of the box removal to the site,
These water collecting basins 10 will be made to order at the factory.

FIG. 2 shows an enlarged cross section of the vicinity of the opening 20 in order to show the structure of the opening 20 of the water collecting basin 10 of this example. An angle 22 for receiving the lid 5 is embedded in the notch 21 of the opening 20. The lid receiving angle 22 is formed by combining angle members having an L-shaped cross section into a substantially square shape. An anchor 23 made of an iron rod or the like is attached to the approximate center of the angle member forming each side of the square. In the angle 22 of this example, the anchor 23 is composed of a substantially U-shaped iron bar, and both ends thereof are welded to the outside of the angle 22.

Further, in the angle 22 of this embodiment, inserts 30 are welded and embedded in each of the four corners.
A hole 24 having a diameter corresponding to the insert 30 is formed at a corner of the welded angle 22 of the insert 30, and a hanging rod or the like can be inserted into the inside of the insert 30 through the hole. If the insert 30 is welded to the corner of the angle 22 and embedded in the water collecting basin as in this example,
As the strength that can be expected for the insert 30, the contact area of the angle 22 can be included in addition to the contact area of the insert 30 itself. The angle 22 itself has a large contact area with the main body 11 of the water collecting basin, and furthermore, since the water collecting basin of this example is embedded by using the anchor 23, the contact area affecting the pull-out strength of the insert 30. Is very large. Therefore, even if it is impossible to secure a sufficient curing period from the start of production after receiving an order to the delivery,
Since a sufficiently high substantial adhesive strength can be secured as the insert 30, it can be used for suspending the water collecting basin 10 without anxiety.

Further, the insert 30 is provided at the corner of the angle 22.
Since it is set to face upward, the insert 30 is embedded in the corner portion of the body 11 of the water collecting basin.
Therefore, the long insert 30 can be inserted so that a long hanging bolt can be inserted in consideration of the load at the time of lifting the water collecting basin, and the attachment area of the insert 30 can be sufficiently secured.
Even when burying, the insert can be buried at the corner without interfering with the box removal formed on the side wall of the main body 11.

Further, the insert 3 is provided at the corner of the angle 22.
If you prepare 0, after installing a water collecting basin on the spot,
The insert 30 can be hidden simply by mounting the grating lid 5. When the insert is embedded in the upper part of the water collecting basin, for example, if the insert is buried outside the angle 22, it is necessary to fill the insert with mortar etc. after the burying the water collecting basin due to the appearance problem. There is. However, by embedding the insert 30 inside the angle 22 as in this example, the trouble of filling the mortar can be saved.

FIG. 3 shows how the water collecting basin of this example is manufactured in a factory. The water collecting basin of this example can also be manufactured by using a durable formwork like other concrete prefabricated concrete products. First, the inner formwork 42 that defines the inner surface of the water collecting basin is installed on the base 41, and the outer formwork 43 that defines the outer surface of the water collecting basin is installed at a predetermined interval. Then, the substantially square angle 22 in which the anchor 23 and the insert 30 are welded is set on the base 41 through the outside of the inner mold 42. A water collecting basin can be manufactured by injecting concrete into the thus assembled formwork as shown by an arrow 45.
When the water collecting basin is manufactured at the factory, it can be manufactured by using a durable frame such as an iron plate, and also steam curing can be performed, so that the inner and outer surfaces of the water collecting basin can be accurately and cleanly finished. Further, since the upper part of the water collecting basin exposed after the water collecting basin is buried in the road surface or the like is also defined by the base 41 and finished in a flat shape, it is possible to save the labor of raising the iron on the spot.

In order to prepare a box opener on the side wall of the water collecting basin,
Between the outer mold 43 and the inner mold 42, it is necessary to put a box-extracting sleeve 44 formed of expanded polystyrene or the like. Since the location of the box removal differs from site to site, the sleeve 44
The position of is also different for each collecting basin. Therefore, if the insert is embedded in the side wall of the water collecting basin, it may interfere with the sleeve 44 and cannot be embedded in a fixed position. However, if the insert is embedded in the upper part of the water collecting basin as in this example, there is no interference with the sleeve 44, and the insert can be installed at an optimum place for suspending the water collecting basin. Further, in this example, since the insert 30 is welded to the angle 22 in advance, there is an advantage that the insert 30 can be embedded at a predetermined position only by embedding the angle 22.

The manner in which the water collecting basin is lifted up in this example will be described with reference to FIGS. 4 and 5. In the water collecting basin 10 of this example,
Since the inserts 30 are embedded in the four corners of the edge of the opening 20, eye bolts 35 are inserted as hanging bolts into each of the inserts 30. And this eyebolt 3
A wire 36 is hung on 5, and the water collecting basin 10 is suspended by a crane 37 or the like and moved vertically. In the water collecting basin of this example, the insert 30 is embedded by using the edge of the opening 20 so as not to interfere with the box openers 16 to 18 provided on the side wall, so that it can be used at the time of lifting. If you do not bury such an insert, do not damage the box opener 1
You have to turn the wire and lift it while covering 1 and it takes time just to set the wire.
Even if the wire is turned up and lifted up, the water collecting basin 10 can only be lifted up diagonally, so the posture between the hangings is not stable. However, by embedding the insert 30 in the upper part like the water collecting basin 10 of this example, the main body 11 can be lifted and hung while the main body 11 extends in the vertical direction. Therefore, the posture can be stabilized during the suspension. Further, even when the main body is lowered to a warehouse, a transporter, or a burial site, the work can be performed with the main body extending in the vertical direction, so that the main body can be easily carried to a predetermined position. Further, it is possible to prevent the trouble that the load is concentrated on one corner of the main body 11 and the main body is chipped when the main body 11 is raised or lowered. In particular, for products such as the water collecting basin of this example, where the period from ordering to delivery is short, and the body must be handled carefully in the factory without a sufficient curing period, handle the product in a stable posture. What you can do is important. Since the water collecting basin of this example can be lifted easily and securely in this way using the buried insert, it is easy to transport and facilitates handling in the factory, and at the same time during transportation or on site. Will be easy to construct.

In the water collecting basin of this embodiment, the grating lid is described as an example, but an iron plate lid or the like may be used. In addition, the position of the box and the number of boxes for connecting buried pipes can be freely selected depending on the site,
Of course, it is possible to provide not only the side walls of three sides but also the side walls of four sides or two sides with a box opener. Further, even if the insert is not welded to the angle, by using the corner of the water collecting basin, it is possible to bury the insert that can always secure a sufficient adhesion area while preventing interference with the box remover. In addition, in this example, the inserts are embedded in the four corners of the water collecting basin, but if the inserts are embedded in at least two corners lined up diagonally, it is possible to have a stable posture when carrying. Can hold.

[0026]

As described above, the water collecting basin according to the present invention can be prefabricated at the factory and easily on site, and
Safe and reliable delivery. Therefore, the water collecting basin, which was conventionally constructed according to the situation at the site, can be replaced with a factory product, and the labor of assembling and manufacturing the formwork at the site can be saved. In addition, since the factory products with good surface finishes can be used for construction, the on-site finish will be easier and the construction period will be greatly shortened. Therefore, by using the water collecting basin according to the present invention and the construction method using the same, the number of skilled workers is reduced, and it is possible to appropriately cope with the recent situation in which many works must be performed in a short construction period. it can. And
By using the water collecting basin according to the present invention, it is possible to reduce the load on the worker and to perform good quality water collecting basin and construction using the water collecting basin.
