Description

FORM FOR RAISING RAINWATER GUTTER OPENING

The present invention relates to a formwork for raising a rainwater receiving opening, and more specifically, to a formwork for raising a rainwater receiving opening in which a rainwater receiving barrel is buried at a location where a road boundary stone is to be installed, adjacent to the center of a road, or offset from the edge of the road, a fixed plate is placed at a rainwater receiving opening, and a plate is placed on one side of the fixed plate.

In general, sewer pipes are divided into rainwater pipes and sewage pipes, and are divided into combined and separate types depending on whether rainwater pipes and sewage pipes are separated. In separate sewer pipes, rainwater pipes are designed to drain only rainwater or surface water from roads, unlike sewage pipes that discharge domestic sewage or factory wastewater. For this purpose, rainwater catchers are installed on both sides of the road.

When constructing this type of rainwater drain, cement is poured on the top of the rainwater drain to form an L-shaped gutter connected to the boundary stone. To form the L-shaped gutter, a formwork for the rainwater drain is installed on the inner upper side of the rainwater drain, and after the L-shaped gutter is constructed, the formwork is separated and removed from the rainwater drain.

These conventional rainwater gutter formworks were made by workers using plywood and lumber to nail them into a square shape to fit the inside size of the rainwater gutter, and then forcibly fitting the manufactured formwork into the inside of the rainwater gutter. In this case, if the size of the manufactured formwork was considerably smaller than the inside size of the rainwater gutter and was not forcibly fitted into the formwork but was inserted loosely, stones were inserted between the formwork and the rainwater gutter to secure the formwork into the rainwater gutter.

In addition, after the L-shaped rainwater drain was formed, the plywood and lumber of the formwork were disassembled by hitting them with a hammer or similar tool and separated from the rainwater drain.

The conventional formwork for rainwater gutters was roughly made by workers using plywood or the like each time construction was performed and installed on the rainwater gutters. After the L-shaped gutters were completed, the formwork was broken down and separated from the rainwater gutters. Therefore, when the formwork was reused, additional manufacturing time was required, which resulted in a problem in that the overall construction time was long.

In addition, since the manufactured formwork is fixed in size, the standards and methods for forming the inner corners of the rainwater gutters are different for each rainwater gutters manufacturer and for each on-site casting, making it very difficult to install it to fit each different formwork.

Republic of Korea Utility Model Registration No. 20-0483315 (Registered on April 20, 2017)

However, when describing the operating principles of preferred embodiments of the present invention in detail, if it is determined that a specific description of a related known function or configuration may unnecessarily obscure the gist of the present invention, the detailed description thereof will be omitted.

Additionally, the same drawing symbols are used for parts that have similar functions and actions throughout the drawing.

In addition, when a part of the specification is said to be 'connected' to another part, this includes not only cases where it is directly connected, but also cases where it is indirectly connected with other components in between. Also, 'including' a component does not mean excluding other components, unless otherwise stated, but rather includes other components.

Hereinafter, a formwork for raising a superior receiving opening according to a preferred embodiment of the present invention will be described in detail with reference to the attached drawings.

As shown in Fig. 1, the formwork (10) for raising a superior receiving opening according to an embodiment of the present invention includes a main body (100), a long plate turnbuckle part (200), and a single plate turnbuckle part (300).

More specifically, as illustrated in FIG. 1, a formwork (10) for raising a rainwater receiving opening according to an embodiment of the present invention comprises a first body (110) in which both sides of a plate (111) are bent to form a single plate (112), a second body (120) arranged to face the first body and seated on the upper portion of the rainwater receiving opening, a plate turnbuckle part (200) for adjusting the spacing between the plates facing each other by connecting the lower portions of the respective plates of the first body and the second body to each other so that the main body is pressed against and spaced apart from the inner surface of the opening, and a single plate turnbuckle part (300) for adjusting the spacing between the single plates facing each other by connecting the single plates of the main body to each other.

Here, the 'opening' described throughout the specification means a sewage catcher, a rainwater catcher, and a collection well, and may be described interchangeably as a sewage catcher and a rainwater catcher. In addition, the opening is a rectangular rainwater catcher or sewage catcher that collects rainwater, domestic sewage, etc. and is installed on a road gutter to connect it to a river or sewage collection area.

Such an opening (11) is installed between the curbstone of the road and the L-shaped side gutter as shown in FIGS. 4 and 5, and the opening impression formwork (10) of the present invention is installed on the upper part of the opening (11). Then, concrete is poured around the formwork (10) to raise the entrance of the opening (11), and the grating is installed to complete the construction.

For example, if the rainwater collection tank is not buried in the correct location, it is difficult to use the formwork. The underground culvert (concrete tank) is buried with the inlet aligned to the subbase height, and then the height of the rainwater collection tank inlet is raised to match the height of the side ditch finish surface when the L-shaped side ditch is constructed as a subsequent process. The additional raised height is approximately 20 cm (15 cm or 25 to 30 cm) depending on the design. At this time, there are many cases where the rainwater collection tank is not buried in the correct location due to measurement errors, worker negligence, fault, and other various reasons during the process of burying the manhole underground.

In addition, if the sewage catch basin is buried inward (towards the center) of the road, it may come into contact with the formwork for installing the side gutter, or the installation of the side gutter formwork may be impossible. In this case, the width of the road side of the raised sewage catch basin is too narrow, causing it to break, resulting in poor construction, which may cause erosion of the lower part or damage to the road. On the other hand, if it is slightly offset towards the road side, it may hit the curb stones to be constructed later, making grating installation impossible, or the curb stones may become warped, resulting in poor construction.

Referring to Fig. 1, the main body (100) is a formwork that is installed on the upper part of the receiving opening to prevent concrete from flowing into the opening when pouring concrete and to raise the entrance of the opening.

This main body (100) is formed by a first body (110) in which both sides of a plate (111) are folded to form a single plate (112), and a second body (120) that is positioned facing the first body (110) and is installed on the upper part of the opening for receiving the rainwater. In addition, the first body (110) and the second body (120) are formed in a box shape in a ㄷ shape with one side open, and can be formed of synthetic resin, plywood, metal material, etc.

In addition, the second body (120) has a plate (121) that is bent on both sides to form a single plate (122) in the same shape as the first body (110), so that the end surface of the single plate (112) of the first body (110) and the end surface of the single plate (122) of the second body (120) are adjacent to or spaced from each other, so that the plate (111) of the first body (110) and the plate (121) of the second body (120) are adjacent to or spaced from each other.

In addition, the main body (100) may further include an auxiliary angle pipe (130) formed on the inner upper portion of the plate (111, 121) of either the first body (110) or the second body (120). The auxiliary angle pipe (130) enables the main body (100) to respond to a tensile force applied to the upper portion due to concrete pouring.

As shown in FIGS. 1 and 2, the main body (100) is formed as a pair spaced apart from each other at the bottom of the plate (111), and further includes a fastening rail (140) extending toward the plate (121) of the second body (120).

The fastening rail (140) allows the insertion of bolts, nuts and washers provided in the slim plate (510) of the fixed plate portion (500) described later, and fastens them with nuts to firmly connect the main body portion (100) and the fixed plate portion (500) to each other.

At this time, the fastening rail (140) is not limited in shape as long as it has a shape into which a bolt, nut, or washer can be inserted, and although not shown in the drawings of the specification of the present invention, a connecting body connecting the spaced apart parts and a reinforcing body connecting toward the center of the plate (111) at the part where each fastening rail (140) and the connecting body are connected can be further formed.

Referring to Fig. 1, the plate turnbuckle part (200) connects the lower portions of each plate (111, 121) of the first body (110) and the second body (120) to each other and adjusts the spacing between the plates (111, 121) facing each other so as to bring the main body part (100) into close contact with and space away from the inner surface of the opening.

Here, the plate turnbuckle part (200) is formed by a generally known turnbuckle or is not limited to a turnbuckle as long as it can adjust the distance between each plate (111, 121) of the first body (110) and the second body (120).

Referring to FIGS. 1 and 2, the single plate turnbuckle part (300) connects the single plates (112, 122) of the main body part (100) to each other and adjusts the spacing between the single plates (112, 122) facing each other. After concrete is poured around the main body part (100), the distance between each single plate (112, 122) is made adjacent to enable the main body part (100) to be demolded.

Meanwhile, as shown in FIGS. 2 and 3, the formwork (10) for raising the opening of the superior receiving portion according to the embodiment of the present invention includes a main body adjusting portion (400) and a fixed plate portion (500).

The main body control unit (400) is composed of a vertical angle pipe (410) coupled in a direction perpendicular to the single plates (112) on both sides of the first body (110) and a sliding hole (420) formed in the upper part of the vertical angle pipe (410) in the direction of the second body (120).

The vertical angle pipe (410) is connected to the inner surface of one end of the single plate (112) of the first body (110) along a straight line passing through the vertical center. In addition, when the single plate (112) of the first body (110) and the single plate (122) of the second body (120) are brought into contact with each other by operating the long plate turnbuckle part (200), the other end of the vertical angle pipe (410) is positioned on the inner surface of the single plate (122) of the second body (120). As a result, even if a tensile force is applied to the main body part (100), each single plate (112, 122) can be prevented from bending.

And, single-plate turnbuckle parts (300) are installed on the upper and lower parts of the vertical angle pipe (410) respectively to form a pair. This is because, when pouring concrete around the main body (100), a greater tensile force is applied to the lower part of the main body (100) than to the upper part, so it is preferable to form single-plate turnbuckle parts (300) as a pair in order to firmly support the lower part of the main body (100).

A sliding hole (420) is formed in the upper part of the vertical angle pipe (410) in the direction of the second body (120). This sliding hole (420) is coupled to a sliding projection (430) described later, thereby allowing the sliding projection (430) to move back and forth in a straight line.

Referring to FIG. 2, the main body adjustment part (400) forms a sliding projection (430) that can move along a sliding hole (420) on the inner surface of the single plate (122) of the second body (120), thereby limiting the maximum distance between the end surfaces of the single plate (122) of the second body (120) and the single plate (112) of the first body (110).

In addition, the main body adjustment part (400) is arranged so that the first body (110) and the second body (120) are spaced apart from each other or in contact with each other as desired, and a nut is provided so that the nut is firmly positioned on one side of the sliding hole (420) and is screwed onto the sliding projection (430).

Referring to Fig. 3, the fixed plate (500) is formed as a slim plate (510) that is positioned on one side of the upper portion of an opening (11) formed in a portion where a road boundary stone (12) is installed or where a formwork (13) for side ditch pouring is installed.

The slim plate (510) is formed as a thin plate and is installed on the upper side of the opening (11) to close the inner side of the opening (11). In addition, the main body (100) can be installed on the upper surface of the slim plate (510).

To this end, it is preferable that the fixed plate (500) be secured with one side of the slim plate (510) 3 mm to 7 mm on one side of the upper side of the opening (11). This is to minimize the gap between the concrete poured around the upper side of the opening (11) and the main body (100) when the fixed plate (500) is removed after the concrete pouring is completed, thereby minimizing the width of the slim plate (510) placed on the opening (11), thereby allowing the fixed plate (500) to be easily removed.

This is to prevent the cured concrete from falling into the opening (11) or cracking of the concrete.

In addition, it is preferable to form a horizontal angle tube (530) on the lower surface of the slim plate (510) so that the slim plate (510) can be placed on the upper part of the opening (11) at the distance described above.

In addition, referring to FIG. 3, it is preferable that the fixed plate part (500) forms a clamp (520) on the other side of the slim plate (510) so that one end of the clamp (520) is in close contact with the inner surface of the other side of the opening part (11).

That is, the clamp (520) is formed on the lower surface of the slim plate (510) and is formed to protrude from the other side of the slim plate (510). Then, the clamp (520) is spirally rotated in one direction so that the end of the clamp (520) is in close contact with the inner surface of the other side of the opening (11). In addition, the clamp (520) is spirally rotated in the opposite direction so that it is separated from the inner surface of the other side of the opening (11), thereby allowing the slim plate (510) to be demolded.

As illustrated in Fig. 3, the fixed plate (500) can be removed by pouring concrete around the main body (100) and curing it, then rotating the slim plate (510) toward the bottom of the opening (11) by moving the clamp (520) away from the inner surface of the other side of the opening (11). To this end, the clamp (520) described above is operated to make the other side of the slim plate (510) movable, and the clamp (520) is pushed toward the bottom of the opening (11) so that one side of the slim plate (510) is moved away from the upper part of the opening (11) and demolding becomes possible.

The process of installing a formwork (10) for raising a receiving opening according to an embodiment of the present invention will be explained through a case where a receiving opening (11) is incorrectly installed as shown in FIGS. 4 and 5.

First, referring to Fig. 4, if an opening (11) is formed in the area where a road boundary stone (12) is to be installed, it is impossible to place the main body (100) on top of the opening (11). In order to place the main body (100) on top of the opening (11), there is a conventional method of reconstructing the opening (11), but this delays the construction time and increases the construction cost due to the reconstructing.

To improve the problems of the prior art, the present invention secures one side of the fixed plate (500) to one side of the upper portion of the opening (11).

At this time, it is preferable to allow one side of the slim plate (510) to be settled at 3 mm to 7 mm on the upper side of the opening (11), and to adjust the distance between each of the long plates (111, 121) of the first body (110) and the second body (120) so that the lower side of the main body (100) is spaced apart from the upper side of the opening (11) by a desired distance (L1) or to adjust the direction so that it is settled on one side of the slim plate (510).

Here, it is preferable that the desired distance (L1) be spaced apart by the amount of space that the grating frame surrounds the outer side of the main body (100).

Then, the main body (100) is installed on the upper part of the slim plate (510) by inserting the bolt, nut and washer provided on the slim plate (510) into the fastening rail (140) formed on the lower part of the main body (100). At this time, it is preferable to place the long washer on the fastening rail (140) and then fasten the butterfly nut.

In addition, the long plate turnbuckle part (200) is widened and fixed to the inner side of the opening (11), and the bolt nut that connects the first body (110) and the second body (120) is loosened to slightly space the distance between them and then tightened. In particular, the width is widened to match the grating standard, but the upper part is wider than the lower part, so that demolding can be easily done.

In addition, the single plate turnbuckle part (300) formed on the single plate (112) of the first body (110) is rotated in one direction to fasten the sliding projection (430) formed on the second body (120) to the sliding hole (420), thereby adjusting the distance (L) between the first body (110) and the second body (120) to meet the grating specifications.

In this way, it is desirable to place the main body (100) on the upper part of the opening (11) and then pour concrete.

Referring to Fig. 5, when an opening (11) is formed in a portion where a formwork (13) for side casting is to be installed, a slim plate (510) of a fixed plate (500) is installed corresponding to the upper side of the opening (11).

The process of installing the main body (100) of the present invention at a location where an opening (11) is formed in the part where the formwork (13) for side casting is to be installed is in a direction opposite to the direction of FIG. 4 described above, so refer to the description of FIG. 4.

Therefore, the formwork (10) for raising the receiving opening according to the embodiment of the present invention can be fixed by fixing the fixed plate part (500) to the opening part (11), fixing the main body part (100) on top of the fixed plate part (500), and then adjusting the distance and direction to match the grating specifications by the main body adjustment part (400) to fix the first body (110) and the second body (120).

In addition, after the concrete pouring is completed, the clamp (520) can be released to lower the slim plate (510) toward the bottom of the opening (11) for easy demolition.

Meanwhile, as shown in FIGS. 6 and 7, the formwork (10) for raising the superior receiving opening according to the embodiment of the present invention may include an extension part (600) and a safety cover part (700).

The extension part (600) is formed as an extension body (610) that is formed at a predetermined height and is installed on the upper part of the main body (100), and is used when the rainwater receiving tube is buried deep in the ground or when the rainwater receiving height is higher or thicker than the general standard.

This extension (600) further includes a reinforcing frame (620) and a support piece (630).

The reinforcing frame part (620) connects the long plate and the short plate of the extension body (610) to each other and prevents deformation of the shape in response to the tensile force applied to the extension body (610).

The support member (630) is formed as a plate that is formed to be in close contact with the upper inner surface of the main body (100) at the lower part of the extension body (610). That is, at least one support member (630) is formed on each of the lower parts of the long plate and the short plate of the extension body (610), so that the upper part is joined to the lower part of the extension body (610), and the lower part is in close contact with the upper inner surface of the main body (100), thereby serving to firmly position the extension body (610).

The safety cover part (700) is formed as a cover body that opens and closes the upper part of the main body part (100). In addition, the safety cover part (700) is connected to the upper part of the extension part (600) in Drawing 7 of the specification herein, but it may also be connected to the upper part of the main body part (100).

This safety cover (700) prevents the concrete from being buried inside the opening (11) when pouring concrete with ready-mixed concrete, and can prevent safety accidents such as pedestrians, workers, or other animals falling into the opening (11) or foreign substances being inserted.

In addition, as shown in FIG. 8, the formwork (10) for raising the superior receiving opening according to the embodiment of the present invention may include an auxiliary grating part (800).

The auxiliary grating part (800) is provided with a grid-shaped frame corresponding to the size of the grating frame installed on the outside of the main body part (100) and serves to be installed in the opening part (11) after the main body part (100) is removed. As a result, it is possible to temporarily replace the grating that is to be permanently installed from after the main body part (100) is removed until the grating is installed, thereby preventing the occurrence of safety accidents during the blank period.

As described above, the detailed description of the present invention has described preferred embodiments of the present invention, but this has been described as an example of the best embodiment of the present invention and does not limit the present invention. In addition, it goes without saying that anyone with ordinary knowledge in the technical field to which the present invention belongs can make various modifications and imitations within the scope that does not depart from the technical idea of the present invention.

Therefore, the scope of the present invention is not limited to the above-described embodiments, but can be implemented in various forms of embodiments within the scope of the appended claims. In addition, it is considered that various modifications can be made by anyone with ordinary skill in the art to which the invention pertains without departing from the gist of the present invention claimed in the claims, and are within the scope of the claims of the present invention.
