Description

Piping {PIPE}

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to piping embedded in a basement or a structure, and more particularly, to piping having increased strength against earth pressure and load.

In general, piping is a facility for continuously transporting various fluids such as water, oil, water / sewage, chemicals, etc. to a destination. Such pipes are made of various materials suitable for the purpose of use, installation environment, etc. For example, pipes made of metal, concrete, or synthetic resin are used.

In such a pipe, the pipe of metal material requires a high production cost due to the expensive material cost, and the weight thereof is heavy, which makes it difficult to store and transport the pipe, and the work such as connection is not easy. There is a risk of corrosion and the use thereof is limited. Accordingly, piping of a nonmetallic material such as synthetic resin is used to replace the metal piping.

On the other hand, pipes are buried in underground structures or structures, depending on the purpose of use or restrictions on places.

Conventional piping is generally formed as a circular pipe. The pipe is provided with reinforcing bars or the like for increasing the strength thereof.

In addition, the piping undergoes loads such as earth pressure as it is buried in the underground or the structure, and the thickness of the piping increases with the buried position, the load of the earth pressure, and the structure.

As described above, in the conventional pipe, as the thickness increases, the installation space increases, the installation becomes difficult, and the material cost increases.

In order to solve the above-mentioned problems, it is an object of the present invention to provide a pipe which improves the internal structure to increase the strength against load without increasing the overall thickness, thereby improving the workability and reducing the material cost .

Also, the pipe body may have a circular outer shape and an inner diameter may be formed to be long in a first direction in which a load acts, and a second direction orthogonal to the first direction may be formed in a short oval shape in comparison with the first direction.

Also, the pipe body may have a circular inner diameter, an outer diameter may be short in a first direction in which a load acts, and a second direction perpendicular to the first direction may be formed in an elliptical shape that is longer than the first direction.

Also, the pipe body may have a thickness corresponding to the second direction that is more than 1 times and not more than 4 times the thickness corresponding to the first direction.

In addition, the marking portion may include printed matter, or may be formed by projecting or recessing a part of the outer diameter portion.

Further, it may further include a pipe covering portion formed on an outer circumferential surface of the pipe main body.

Further, the pipe main body may be formed by extrusion molding.

Hereinafter, a piping according to an embodiment of the present invention will be described with reference to FIGS. 1 and 2. FIG.

FIG. 1 is a perspective view of a pipe according to an embodiment of the present invention, and FIG. 2 is a sectional view of a pipe according to an embodiment of the present invention.

The piping 100 of the present embodiment may include a piping body 110 having a passage through which fluid flows.

Either the inner diameter or the outer diameter of the piping body 110 may be formed in an elliptical shape, and the other may be formed in a circular shape. The piping body 110 may be disposed such that the cross-sectional thickness in the first direction in which the load acts is the minimum, and the thickness in the second direction cross section perpendicular to the first direction is the maximum.

Specifically, the outer diameter of the piping body 110 may be circular in cross section. The inner diameter of the pipe body 110 may be formed to have a predetermined thickness different from the outer diameter of the pipe body 110.

The piping body 110 may be buried in a basement or a structure.

As the piping body 110 is buried in an underground or a structure, it receives a load such as earth pressure from its surroundings. In the upward and downward directions in which a load is concentrated, a large load can be applied to the piping body 110 as compared with the peripheral portion.

In order to increase the load-bearing strength against a large load generated in the upward and downward directions, the pipe 100 of the present embodiment is formed in a circular shape in its outer diameter, and the inner diameter of the cross- For example, an elliptical shape having a longer length in the upward and downward directions and a relatively shorter length in the second direction orthogonal to the first direction, for example, in the leftward and rightward directions, as compared with the first direction .

Specifically, the pipe body 110 may have an outer diameter formed in a circular shape, and an inner diameter of the pipe body 110 may be formed in an elliptical shape having a thick thickness t2 in the left and right directions in comparison with the thickness t1 in the upward and downward directions (I.e., t2 > t1).

The piping body 110 can disperse and absorb the load transmitted from the peripheral portion as a whole, and a load generated largely in the upward and downward directions can be transmitted downward through the side portion of the piping body 110.

In the present embodiment, since the thickness t2 of the side surface portion of the piping body 110 is thicker than the upper and lower thicknesses t1, the pipe 100 has a large strength against the load resistance, It can be dispersed and have a large resistance.

Preferably, the pipe body 110 may have a thickness t2 corresponding to the second direction, that is, the lateral thickness may be thicker than the thickness t1 corresponding to the first direction, i.e., the vertical thickness.

More preferably, the pipe body 110 has a thickness t2 corresponding to the second direction, that is, the lateral thickness is greater than the thickness t1 corresponding to the first direction, that is, at least one time greater than the vertical thickness, May be the same or smaller.

That is, the thickness t2 of the pipe body 110 corresponding to the second direction may be greater than or equal to 1 times and less than or equal to 4 times the thickness t1 corresponding to the first direction.

For example, in the pipe 100 of the present embodiment, when the diameter of the pipe body 110 is small, the thickness t2 corresponding to the second direction, that is, the lateral thickness is the thickness t1 corresponding to the first direction, that is, May be more than one times the thickness in the upward and downward directions.

On the other hand, when the diameter of the pipe body 110 is large, the difference between the thickness t1 corresponding to the first direction and the thickness t2 corresponding to the second direction can be large. That is, the pipe body 110 may have a thickness t2 corresponding to the second direction, that is, the lateral thickness may be formed to be thicker than the thickness t1 corresponding to the first direction, that is, about four times as thick as the vertical direction.

Also, in the present embodiment, the piping body 110 may be provided with a marking unit 120 on at least one of the first direction and the second direction.

The marking unit 120 is configured so that the position of the inner diameter having an elliptical shape in the pipe body 110 can be easily recognized from the outside, and is displayed in a first direction in which a load acts, that is, In a second direction that is a lateral direction orthogonal to the first direction.

Therefore, the piping 100 of the present embodiment can identify the direction in which the piping 100 is installed by checking the marking portions 120 displayed in the upward, downward, or lateral direction in the process of being buried. For example, the marking unit 120 may be displayed only in the upward and downward directions. In this case, if the marking unit 120 is positioned in the upward and downward directions, the elliptical shape inside the pipe 100 may extend upwardly and downwardly As shown in FIG.

In this case, if the side where the marking unit 120 is located is positioned in the left and right directions, the elliptical shape of the inside of the pipe 100 becomes the upper and lower sides, Can be arranged in a long direction.

In addition, the marking unit 120 may be a printed matter printed on the outer circumferential surface of the pipe body 110 with ink, paint, or the like. The marking unit 120 can directly display and print the fact that it is an upward, downward, leftward, or rightward direction. In addition, the marking unit 120 displays the manufacturer, specification, etc. of the product, It is also possible to do.

Further, the marking unit 120 may be displayed in various ways besides being made of printed matter. For example, the marking portion 120 may include a surface treatment portion formed on the outer diameter portion of the pipe body 110.

It is also possible that the surface treatment section protrudes or depresses (engraves) a part of the outer diameter portion so that the constructor can recognize it.

In other words, the surface treatment section can form a display such as manufacturer, standard, or the like by a protruding member, and the placement direction of the pipe 100 can be determined by confirming the position of the protruding member or engraving.

Meanwhile, in this embodiment, the pipe body 110 may be formed by extrusion molding, and the mark 120 may be integrally formed in the process of extrusion molding, or may be printed and formed during the cooling process.

For example, the piping body 110 may be formed of a synthetic resin material such as polyvinyl chloride (PVC), polypropylene (PP), polyethylene (PE), and engineering plastic.

3 (a) and 3 (b) are cross-sectional views showing the flow height of the piping according to the prior art and the present invention.

3, in the piping 100 of the present embodiment, when the oval inner flow path of the piping body 110 is arranged in the upward and downward directions, when the fluid passes only a part of the lower portion of the piping body 110, It is possible to increase the flow depth compared to the pipe 10 having the conventional circular flow passage area. That is, the piping 100 of the present embodiment can form the water depth h2 higher than the water depth h1 of the conventional pipe when the fluid of the same flow rate passes.

Therefore, the piping 100 of the present embodiment can increase the flow velocity when the same fluid flows, thereby improving the fluidity and effectively preventing the generation of deposits and the like.

In the present embodiment, the piping 100 is described as being arranged in an elliptical shape in the upward and downward directions. However, the installation method, shape and position of the piping 100 are not limited, .

4 is a cross-sectional view of a pipe according to another embodiment of the present invention.

Referring to FIG. 4, the piping 200 may further include a pipe covering portion 230 covering an outer circumferential surface of the pipe body 210.

The pipe covering portion 230 may be formed of the same material as the pipe body 210 or may be formed of a material having a different composition ratio or the like to protect the pipe body 210.

For example, the pipe covering portion 230 may be formed of various materials having impact resistance, such as urethane, rubber, etc., in addition to synthetic resins such as PVC, PP, PE, and engineering plastic. The piping covering portion 230 can prevent the piping body 210 from being affected or damaged from the external environment.

Further, marking portions for indicating the up, down, left, and right directions may be formed on the outer circumferential surface of the pipe covering portion 230. At this time, if the mark part is a printed matter, it can be separately printed on the pipe covering part 230. In addition, when the marking portion (120 in FIG. 1) formed on the piping body 110 is a projecting portion, the marking portion may be projected on the pipe covering portion 230.

5 and 6 are sectional views of piping according to another embodiment of the present invention.

First, referring to FIG. 5, in this embodiment, the pipe 300 can be variously modified to increase the internal strength. For example, at least one reinforcing member 350 may be installed along the longitudinal direction inside the pipe body 310. The reinforcing member 350 may be formed linearly along the longitudinal direction of the piping body 310 and may be installed while being wound helically along the longitudinal direction of the piping body 310.

In addition, in the present embodiment, the piping body 310 is formed to have a greater thickness in the second direction, that is, in the lateral direction than the thickness in the first direction, i.e., the upward and downward directions. The piping body 310 is provided with a reinforcing member 350 adjacent to the second direction, and may be installed in a plurality of rows or zigzags.

This is because the inner side adjacent to the second direction of the pipe body 310, that is, the inner side of the pipe body 310 is formed thick, so that a sufficient space for installing the reinforcing member 350 in a plurality of rows can be formed. The load-bearing strength can be further increased by providing a plurality of rows 350 or zigzags.

6, the reinforcing member 350 installed in the inside of the piping body 310 in the second direction, that is, the inside of the side surface thereof, is connected to another adjacent reinforcing member 351 through the connecting member 355. Further, (350) to form a truss structure.

On the other hand, in the present embodiment, the pipe has a minimum cross-sectional thickness in the first direction in which the load acts and a maximum cross-sectional thickness perpendicular to the second direction, and the outer diameter is circular and the inner diameter is elliptical However, the concrete form may be modified.

7, the pipe 400 may include a pipe body 110 having an outer diameter and an inner diameter different from each other by a predetermined distance, and having a passage through which the fluid passes inside the inner diameter .

The piping body 410 may be disposed such that the cross-sectional thickness in the first direction in which the load acts is the smallest, and the thickness in the second direction cross section perpendicular to the first direction is the maximum.

Specifically, in the piping body 410 of the present embodiment, the inner diameter of the cross-section forming the flow path is increased to increase the load-bearing strength against the large load generated in the upward and downward directions, A pipe body 410 formed in an elliptical shape having a length that is shorter in one direction, for example, an upper and a lower direction, and a second direction perpendicular to the first direction, for example, a length longer than a first direction in the left and right directions .

Specifically, the inner diameter of the pipe body 410 may be formed in a circular shape, and the inner diameter may be formed in an elliptical shape in which the thickness t2 in the left and right directions is thicker than the thickness t1 in the upward and downward directions (I.e., t2 > t1).

The pipe body 410 can disperse and absorb the load transmitted from the peripheral portion as a whole, and a load generated largely in the upward and downward directions can be transmitted downward through the side surface portion of the pipe body 410.

Since the pipe 400 of the present embodiment has a thickness t2 of the side portion of the pipe body 110 that is thicker than the upper and lower thicknesses t1, the pipe 400 has a large strength against the load resistance, So that it can have a large resistance.

Preferably, the pipe body 410 may have a thickness t2 corresponding to the second direction, that is, the lateral thickness may be thicker than the thickness t1 corresponding to the first direction, i.e., the vertical thickness.

More preferably, the pipe body 410 has a thickness t2 corresponding to the second direction, that is, the lateral thickness is greater than the thickness t1 corresponding to the first direction, that is, at least one times larger than the vertical thickness, May be the same or smaller.

That is, the thickness t2 of the pipe body 410 corresponding to the second direction may be more than 1 times and not more than 4 times the thickness t1 corresponding to the first direction.

For example, in the pipe 400 of the present embodiment, when the diameter of the pipe body 410 is small, the thickness t2 corresponding to the second direction, that is, the lateral thickness is the thickness t1 corresponding to the first direction, May be more than one times the thickness in the upward and downward directions.

On the other hand, when the diameter of the pipe body 410 is large, the difference between the thickness t1 corresponding to the first direction and the thickness t2 corresponding to the second direction can be large. That is, the pipe body 410 may have a thickness t2 corresponding to the second direction, that is, the lateral thickness may be formed to be thicker than the thickness t1 corresponding to the first direction, that is, about four times larger than the vertical thickness.

Also, in this embodiment, the piping body 410 may be provided with a marking portion (120 in FIG. 1) on at least one of the first direction and the second direction.

The marking unit 120 is configured to allow the position of the inner diameter having an elliptical shape in the piping body 410 to be easily seen from the outside and is displayed in a first direction in which a load acts, In a second direction that is a lateral direction orthogonal to the first direction.

Accordingly, the piping 400 of the present embodiment can identify the direction in which the piping 400 is installed by identifying the marking portions 120 displayed in the upward, downward, or lateral direction during the embedding process. For example, the marking unit 120 can be displayed only in the upward and downward directions. In this case, when the marking unit 120 is positioned in the upward and downward directions, the elliptical shape inside the pipe 400 moves upward As shown in FIG.

In this case, if the side where the mark 120 is located is positioned in the left and right directions, the elliptical shape of the inside of the pipe 400 can be positioned upward, downward, Can be arranged in a long direction.

Since the center of gravity of the pipeline 400 is lower than that of the circular pipeline, the height of the pipeline 400 can be lowered due to vibration, flow, or the like generated during passage of the fluid through the pipeline 400, It is possible to suppress the shaking or moving.

It will be apparent to those skilled in the art that various modifications and variations can be made in the present invention without departing from the spirit or scope of the invention as defined in the appended claims. It will be understood that various changes and modifications may be made without departing from the spirit and scope of the invention.
