{RAINWATER DRAINING FACILITY FOR BUILDING}

The present invention relates to a rainwater drainage system for a building including a drainage pipe for guiding rainwater falling on a roof of a building to a drainage outlet, and more particularly to a rainwater drainage system for a building, The present invention relates to a rainwater drainage system for a building.

Generally, the building is provided with a building drainage system including a drainage pipe for guiding the rainwater falling from the roof to the drainage port. The rainwater falling from the roof is a simple structure that descends down the drainage pipe connected to the bottom of the water-bearing beam with a gradient and drains to the ground through the drainage hole.

1 and 2, the rainwater drainage apparatus basically includes a water-catching beam 1 and a water drainage pipe 5. [

The eaves gutter 1 is a trough installed to have a gradient in the inside of the wall 4 at the eaves of the roof 2 and is often a semicircular shape with a diameter of about 10 cm. In high-end architecture, it is made into a double rectangle with decoration.

The water-catching beam (1) can be deformed by a load when a large amount of rain falls or a foreign matter is deposited due to long-term neglect, and may be twisted by the sunlight. Therefore, Is fixed to the wall (4) adjacent to the roof (2) by rivets, bolts or the like.

The rain leader pipe 5 is a vertical trough connected to the water-bearing rib 1, and the size of the rain leader pipe 5 varies depending on the roof area. However, in the case of houses, a circle having a diameter of about 75 mm is often used.

Although not shown in the drawing, the rainwater drainage apparatus generally includes a roof drain as well as a home hanger.

The roof drain is installed at a drain port through which the water-catching beam 1 and the drainage pipe 5 are connected to each other. The roof drain is used to prevent the water or waste from flowing into the drainage pipe 5 to be clogged It is a cap shaped cover with several holes.

 The grooved hook 6 is used to separate the water drainage pipe 5 from the wall 4 so as to prevent the rainwater from flowing along the wall 4 and to fix the water drainage pipe 5 to the wall 4 Normally, the hook-shaped hooks are butted against each other. However, a considerable degree of skill is required for establishing the groove 6 while keeping the space between the wall 4 and the water drainage pipe 5 in communication with the water-catching beam 1 and the drainage pipe 5. On the other hand, the water drainage pipe 5 installed apart from the wall 4 may also be used for theft of multi-story buildings.

In addition to this, the normal water outlet pipe is long and can not be transported to the installation place after production. It is necessary to manufacture the product by dividing it into several parts at the factory and then connecting the connection part by welding or riveting at the installation site. The operation takes a long time. In addition, it is impossible to know which part is clogged when the clogging due to the foreign material or the like occurs in the conventional drainage pipe, and there is the irrationality that the whole should be removed after the clogging, and also, it is usually installed at the corners of the building (at least four or more places) There is a need for improvement.

However, as disclosed in Korean Patent Laid-Open Nos. 10-2009-0034082 and 11-293870, a screw is built in a water drop pipe to quickly discharge a large amount of water by water pressure, or a foreign matter A technology for solving the above problems has not yet been developed, so it is necessary to develop a technology for this.

Hereinafter, a rainwater drainage system for a building according to an embodiment of the present invention will be described in detail with reference to FIGS. 3 to 6. FIG.

In the drawings, the same reference numerals are given to the same elements even if they are shown in different drawings. In the drawings, the same reference numerals as used in the accompanying drawings are used to designate the same or similar elements. And detailed description of the configuration will be omitted. Also, directional terms such as "top", "bottom", "front", "back", "front", "forward", "rear", etc. are used in connection with the orientation of the disclosed drawing (s). Since the elements of the embodiments of the present invention can be positioned in various orientations, the directional terminology is used for illustrative purposes, not limitation.

3, the building rainwater drainage apparatus according to one embodiment includes a water drainage pipe 500 connected vertically to a water-receiving beam 1 having a gradient at an eave end of a roof 2, (700) for raising and lowering the lifter (500).

The water outflow pipe 500 is divided into a plurality of upper and lower troughs 510, 520 and 530 and a lower end trough 540 in a folded manner. Here, the upper trough 510 is connected to the roof 2 or the water-catching beam 1, and the lower trough 540 is connected to the wire 720 to move up and down according to the manual operation of the user. The intermediate troughs 520 and 530 are located between the upper troughs 510 and the lower troughs 540 and protrude and retract between the upper and lower troughs 510 and 540. The number of the middle troughs 520 and 530 can be appropriately adjusted according to the height of the building.

Referring to FIGS. 4A and 4B, in this embodiment, the middle troughs 520 and 530 are two-tiered. In this case, the downcomer 500 includes an upper trough 510, a first trough 520 , A second trough 530 and a lower trough 540. [ Here, the intermediate troughs 520 and 530 refer to the first trough 520 and the second trough 530, and the lower trough 540 includes the catching jaw 546 and the wire binding portion 548. At this time, the diameter gradually increases from the upper trough (510) to the lower trough (540).

That is, the lower trough of the upper trough (510) is formed to be larger than the upper diameter of the first trough (520), the lower trough of the first trough (520) is formed larger than the upper diameter of the second trough The second trough 530 is formed to have a lower diameter larger than the upper diameter of the lower trough 540 so that the lower trough 540 contacts the second trough 530 while the second trough 530 contacts the first trough 520 And the first trough 520 is held in contact with the upper trough 510 to maintain the stretched state.

5 (a) and 5 (b), a bottom trough 540 is positioned at the outermost side, and a second trough 530, a first trough 520, do. This is possible because the wire 720 is held by the lower trough 540 while the lowering trough 546 of the lower trough 540 rests against the lowering of the first trough 520 and the second trough 530. In addition, the engaging protrusion 546 may be formed with sufficient thickness and strength to prevent the first and second troughs 520 and 530 from descending.

Here, the material of the water outlet pipe 500 may be suitably selected by a person skilled in the art, such as a galvanized flat bed, a copper plate, or a PVC trough.

Accordingly, since the length of the water discharge pipe 500 is kept as short as possible, it is less likely to be clogged by foreign substances introduced from the outside, easy to clean inside the pipe, and the thief can ride the water discharge pipe 500 There is an advantage that security can be ensured from theft because it can not be intruded. In addition, since only the wire 720 is visible and the wire 720 is also thin, observation at a long distance is not possible and there is an advantage that the beauty of the building is not hurt.

In addition, since the water discharge pipe 500 is transported in a short length from the factory to the installation site during transportation, the transportation is advantageous.

The expansion and contraction means 700 according to an embodiment will be described with reference to FIG.

The expansion and contraction means 700 includes a wire pulley 710 coupled to the outside of the upper trough to be rotatable and having teeth 760 formed on its outer periphery, a wire 720 wound on the wire pulley 710, The rear end of the wire pulley 710 is hinged to the inside of the pulley cap 730 and the front end of the wire pulley 710 is engaged with the teeth 760 of the wire pulley 710, And an elastic means 750 for pressing the engaging member 740 toward the wire pulley 710. When the wire 720 is pulled at the other end of the wire 720, 720 is configured to press the latching member 740 to release the latching member 740 from the teeth 760 of the wire pulley 710 to release the latching.

The operation of the rainwater drainage system according to the present invention having the above structure will be described below.

The length of the water discharge pipe 500 connected to the lower part of the water-bearing beam 1 is kept as short as possible. When the rain is lowered, the user pulls the other end of the wire 720 to move the retaining member 740 to the wire pulley 710 So that when the wire pulley 710 is released little by little in this state, the trough is lowered due to its own weight.

Accordingly, the second trough 530 and the first trough 520, which are supported by the engagement protrusions 546 of the lower trough 540, descend in that order. The lower portion of the first trough 520 is stopped by the lower portion of the upper trough 510 and the upper portion of the second trough 530 is then stopped by the first trough 520. [ And then the upper portion of the lower trough 540 is caught by the lower portion of the second trough 530 and stops. In this way, the water outlet pipe 500 maintains a generally elongated state.

When the water drop pipe 500 is extended, the troughs drop by their own weight, so that there is no need to adjust the vertical degree of the entire water drop pipe separately, which is advantageous in that the construction is convenient.

When the user pushes the other end of the wire 720 while grasping the other end of the wire 720, the wire 720 is lifted and lowered and the lower trough 540 formed with the wire connecting part 548, The hooking jaw 546 of the lower trough 540 is lifted up while lifting the lower end of the second trough 530. Then, the lower end of the first trough 520 is lifted while lifting the end of the first trough 520, so that the shortest extension pipe is finally obtained.

Hereinafter, a building rainwater drainage apparatus according to another embodiment will be described with reference to FIGS. 7 and 8. FIG.

FIG. 7 is a perspective view and a cross-sectional view illustrating an extension state of a rainwater drainage apparatus according to another embodiment of the present invention, and FIG. 8 is a perspective view and a cross-sectional view illustrating a constriction state of a rainwater drainage apparatus according to another embodiment of the present invention. to be.

7 and 8, the plurality of troughs are divided into upper troughs 510, intermediate troughs 520 and 530, and lower troughs 540, respectively, Each of the troughs is tapered so as to expand in diameter from the upper portion to the lower portion. The lower troughs of the upper troughs 510 are formed to be larger than the upper troughs of the intermediate troughs 520 and 530, The lower trough 540 is inserted into the intermediate troughs 520 and 530 while being inserted while the intermediate troughs 520 and 530 are inserted into the upper trough 510 to be held in the extended state, And the lower trough 540 has a discharge hole 801 for discharging water to the side thereof and the lower trough 540 has a detachable stopper 802 to be fitted to the lower end of the stopper 802, 530 support the intermediate troughs 520, Writing is configured to maintain a state of contraction.

The discharge hole 801 is spaced from the lower end of the lower trough 540 by a predetermined distance so that the discharge hole 801 is formed at a position where the lower trough 540 can descend due to the self weight of accumulated rainwater The stopper 802 is configured to close the lower end of the lower trough 540 and is configured to be manually separated by a method such as forcible fitting or screwing.

The operation of the rainwater drainage system according to another embodiment of the present invention will now be described.

Normally, the length of the water discharge pipe 500 connected to the lower part of the water receiving beam 1 is maintained as short as possible. When the rain is lowered, the rainwater flows into the lower trough 540, And the trough is lowered due to the self weight due to the accumulated rainwater.

Accordingly, the second trough 530 and the first trough 520, which are supported by the stopper 802 of the lower trough 540, descend in that order. The lower portion of the first trough 520 is stopped by the lower portion of the upper trough 510 and the upper portion of the second trough 530 is then stopped by the first trough 520. [ And then the upper portion of the lower trough 540 is caught by the lower portion of the second trough 530 and stops. In this way, the water outlet pipe 500 maintains a generally elongated state.

When the water drop pipe 500 is extended, the troughs drop by their own weight, so that there is no need to adjust the vertical degree of the entire water drop pipe separately, which is advantageous in that the construction is convenient.

At this time, the rainwater continuously flowing into the trough is discharged to the discharge hole 801 formed in the side surface of the lower trough 540.

In addition, when the rain stops and the water outlet pipe 500 is to be retracted, the user separates the stopper 802 from the lower trough 540, discharges the accumulated rainwater and then joins again, and grips the other end of the wire 720 The wire 720 is lifted and lowered and the lower end trough 540 having the wire connecting portion 548 is lifted and lowered together with the wire 720. At this time, And rises while lifting the lower end of the trough 530. Then, the lower end of the first trough 520 is lifted while lifting the end of the first trough 520, so that the shortest extension pipe is finally obtained.

Here, since the wire 720 is made of metal such as stainless steel, deformation is limited under an external force of a certain size, thereby preventing elongation of the trough.

As described above, the building rain drainage system according to another embodiment has the merit that the apparatus can be constructed more simply because only the wire 720 and the wire pulley 710 are provided as the expansion and contraction means, unlike the embodiment described above.

Although the present invention has been described in detail with reference to the drawings, the present invention is not limited thereto.
