Description

Concrete rooftop waterproofing layer autonomous exhaust system {AUTONOMOUS EXHAUST SYSTEM FOR WATERPROOF LAYER ON CONCRETE ROOFTOP}

The present invention relates to a concrete rooftop waterproofing autonomous exhaust system that simplifies the structure, improves assembly, improves maintenance convenience, and more effectively prevents the backflow of rainwater on the rooftop.

Waterproofing is essential because the concrete rooftop slab of a building structure is vulnerable to waterproofing. The waterproof layer refers to the waterproof sheet. When the moisture on the surface of the concrete is heated by the sun and evaporated, the gas generated by the hydration reaction of cement is not released into the atmosphere and remains, causing the waterproof sheet to swell. If the swelling becomes extreme, the waterproof sheet cracks or bursts, causing water leaks. I do it.

With this in mind, a degassing device for protecting the rooftop waterproof layer was proposed. Registered Patent No. 10-1218582 is a representative example. This prior art involves drilling a vertical bar by drilling a plurality of insertion holes in the upper flange of the main body whose center is fastened to the support bar and the support bar welded to the center of the upper surface of the fixing plate that is seated between the rooftop surface of the concrete structure and the waterproofing sheet. Insert a degassing section with a blocking rod for blocking rainwater infiltration in each vertical rod, and a degassing section that is seated on the upper flange of the main body to protect the degassing section and to the lower outer periphery so that water vapor and gas rising inside the main body are exhausted to the outside. It consists of a cover with a discharge hole, and a packing to prevent rainwater infiltration mounted on the bottom of the fixing plate of the support, the bottom of the lower flange of the main body of the degassing unit, and the inner periphery of the cover.

If the drain on the roof is partially blocked by fallen leaves, waste plastic, etc., making it difficult to drain, or if the water level rises above the bottom of the discharge hole because rainwater during heavy rain does not drain smoothly and accumulates, rainwater flows back through the discharge hole. It may flow inside the cover. What prevents this phenomenon is a cylindrical vertical rod and a blocking rod inserted into it to replace the floating valve.

When the water level rises near the top of the vertical rod, the blocking rod floats and blocks the exhaust hole in the vertical rod area at the upper edge of the degassing unit, preventing rainwater from penetrating into the inside of the cover.

In this structure of the rooftop waterproof sheet protection deaerator, rainwater backflow prevention means are scattered in several places on the upper edge of the deaerator. This is based on the premise that all blocking rods are always maintained in a normal operating state. As the number of vertical rods and blocking rods increases, fine dust becomes trapped between the inner peripheral surface of the vertical rod and the outer peripheral surface of the blocking rod, interfering with the operation of the blocking rod. If the water level rises more than necessary due to any factor, there is a possibility that prevention of rainwater backflow may be disrupted.

In addition, it is divided into a tubular fastening rod integrated with an external thread in the center of the upper surface of the flat washer-type fixing plate, and a degassing body body in which the upper rim and the lower rim are formed integrally at the top of the tubular body formed with an internal thread fastened to the external screw. The degassing unit, which consists of a set of vertical rods and blocking rods installed in each of the plurality of vertical rod holes formed on the upper edge of the degassing unit main body, has a large number of parts, so the cost burden is high, assembly is slow, and it is not easy to replace defective parts.

Meanwhile, the electricity produced from the solar cell installed on the ceiling of the cover is stored in the storage battery, and the lighting device that turns on the LED when the sunset is detected by the illuminance sensor has a single LED and is of the downward illumination type, so the transparent window of the cover Therefore, the lighting effect is dim and the lighting effect is low.

(Patent Document 0001) Registered Patent No. 10-1218582

The present invention provides a concrete rooftop waterproofing autonomous exhaust system that simplifies the structure, improves assemblyability, improves convenience of maintenance, and reliably blocks the backflow of rainwater.

In addition, the present invention provides an autonomous exhaust system for a concrete rooftop waterproofing layer that can enhance the nighttime decorative lighting effect on the rooftop.

The object of the present invention described above is to include a main body having a main exhaust hole that is centered with an exhaust hole drilled in the center of a flat washer-type ground plate in close contact with the surface of a rooftop; A rainwater backflow blocking valve that opens and closes the top of the main exhaust hole of the main body; a valve spring that elastically presses the valve to exhaust water vapor and gas and block backflow of rainwater; a spring pad for supporting the top of the spring installed on the valve spring; It can be implemented as an autonomous exhaust system with a concrete rooftop waterproof layer consisting of a shade covering the main body.

The structure of the main body is simplified by excluding the upper and lower edges from the main body of the degassing unit of the conventional deaerator.

And water vapor flowing into the main exhaust hole of the main body, water vapor escaping through the top of the main exhaust hole that opens when the valve is pushed up by the pressure of the gas, and the exhaust hole through which the gas diffuses into the atmosphere are perforated on the upper half of the main wall of the main body. do. The valve is a flange-integrated type that is in close contact with the top of the main exhaust hole.

Even if the valve pressed by the valve spring blocks the top of the main exhaust pore, the pressure of water vapor and gas generated on the rooftop and flowing into the main exhaust pore of the main body is bound to gradually increase. When the pressure reaches a certain level, the valve is released into the valve spring. It rises while compressing, opens the top of the main exhaust pore, falls into the mooring space above the main exhaust pore, and then disperses into the atmosphere through the exhaust hole.

Even if the water level on the roof rises above the bottom of the exhaust hole of the main body and rainwater flows in, the valve pressed against the valve spring remains firmly blocking the main exhaust hole, so it cannot flow back into the main exhaust hole of the main body.

Another object of the present invention is a rooftop lighting device that installs solar cells on the ceiling of the shade, stores the electricity produced by the solar cells in a storage battery, and turns on the LED when a sunset is detected by the illuminance sensor. By replacing it with multiple upward-emitting LEDs distributed around the perimeter, the lighting effect can be improved with clear LED direct light, and the shade structure is simplified by excluding transparent windows. It can be implemented as an autonomous exhaust system for the concrete rooftop waterproofing layer.

The autonomous exhaust system for the concrete rooftop waterproofing layer according to the present invention is a tubular fastening rod with external thread and an integrated upper and lower border, unlike the conventional degassing device that consists of a degassing unit body fastened to the fastening rod and a plurality of vertical rod-blocking rod sets. The structure of the degassing device is very simple as it has been reorganized into a simple structure of a ground plate-integrated body, a single valve, and a valve spring for valve pressure, and the cost is greatly reduced by reducing the number of parts, and assembly is also improved.

In addition, even if rainwater from the rooftop where the water level has risen flows into the exhaust hole drilled on the main wall of the main body, the valve can very effectively prevent it from flowing into the main exhaust hole of the main body by blocking the top of the main exhaust hole.

In addition, the plurality of upward-illuminating LEDs distributed on the ceiling of the shade provide clear and intense LED light, maximizing the nighttime decorative lighting effect on the rooftop.

Figure 2 is a longitudinal cross-sectional view of the case where the concrete rooftop waterproof layer autonomous exhaust system of the present invention is installed between the rooftop and the waterproof sheet.
Figure 3 is a diagram showing the situation when exhausting water vapor and gas.

Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

Figure 1 is a perspective view of a concrete rooftop waterproofing autonomous exhaust system according to the present invention. In this picture, the autonomous exhaust system of the concrete rooftop waterproofing layer is covered with a shade (20) on an integrated body with a ground plate (11). A solar cell 21 is located in the center of the ceiling of the shade 20, and a plurality of LEDs 22 are arranged around the solar cell 21. The LED 22 is an upward direct lighting type whose top is exposed to the ceiling, and the light emission of the LED is exposed as is, creating a clear rooftop lighting effect.

As shown in Figure 2, which shows a longitudinal cross-section of the concrete rooftop waterproofing autonomous exhaust system according to the present invention, the main body 10, valve 12, valve spring 13, spring pad 14, diaphragm 15, and solar cell It consists of a cell 21 and a shade 20 equipped with a plurality of upward-illuminated LEDs 22.

The main body 10 is a circular pipe with a main exhaust hole 16 formed at the center of the plane, and a flange seat 17 is formed at the top of the main exhaust hole 16. The main exhaust hole (16) is used to exhaust the water vapor and gas generated on the surface of the rooftop, which are blocked by the waterproof layer (L) and cannot spread into the atmosphere, and the water vapor and gas moving along the bottom of the ground plate (11) are vented to the main body (10). It is a longitudinal hole that flows in through the bottom of the.

The flange seat 17 is for seating the flange 18 formed integrally with the top of the valve 12.

An exhaust hole 19 is drilled in the main wall of the main body 10 at the same height as the floor of the mooring space a. This exhaust hole 19 is a hole through which water vapor and gas rising into the mooring space (a) formed at the top of the main body 10 are discharged into the atmosphere.

When the pressure of water vapor or gas entering the main exhaust hole 16 reaches a certain level, the valve 12 rises due to the pressure and opens the upper end of the main exhaust hole 16 to exhaust the water into the mooring space (a). When not exhausting, the upper end of the main exhaust hole 16 is lowered by the expansion force of the valve spring 13, thereby closing the water level on the rooftop higher than the bottom of the exhaust hole 19 on the main wall of the main body 10, allowing rainwater to flow into the mooring space. Even if it enters (a), it blocks backflow into the main exhaust pore (16).

A flange 18 is formed at the top of the valve 12. This flange 18 sits on the flange seat 17 formed at the top of the main exhaust hole 16 and substantially opens and closes the top of the main exhaust hole 16.

The upper end of the valve spring 13 is inserted into a horn protruding downward from the center of the bottom of the spring pad 14 to support it, and the lower end is inserted into a horn protruding from the center of the upper surface of the valve 12 to allow the valve 12 to extend. The top of the main exhaust hole (16) is tilted to close.

The diaphragm 15 is attached to the top of the main body 10 to prevent the spring pad 14 from falling off and at the same time supports the shade 20.

The shade 20 has a transparent or translucent lighting window in the middle of the main wall, and an illuminance sensor 25 and an additional solar cell 21 are installed on the ceiling of the shade 20, so that the power produced there is stored in the containment room 23. When the sunset is detected by the illuminance sensor 25, the LED 22 can be automatically turned on to illuminate the surrounding area.

A jaw 20' is added to the inner peripheral surface of the shade 20 and sits on the edge of the partition 15 to stabilize the covering state of the shade 20.

In addition, the storage room 23 of the shade 20 includes a storage battery 24 that stores electricity produced by the solar cell 21, and an illuminance sensor 25 that detects the sunset and turns on the LED 22 at once. is built-in. The solar cell 21, the storage battery 24, the LED 22, the storage battery 24, and the illuminance sensor 25 are electrically connected.

Insert the valve 12 into the upper part of the main body 10, place the flange 18 on the flange seat 17, insert the lower end of the valve spring 13 into the horn, and install the valve seat 14. Insert it so that the top of the valve spring (13) fits into the horn.

Next, the shade 20 is placed on the main body 10 and placed on the diaphragm 15 to complete the concrete rooftop waterproofing autonomous exhaust system.

It is preferable that the diaphragm 15 is point-joined with silicone so that it can be separated from the main body 10 so that the main body 10, the valve 12, the valve spring 13, and the pad 14 can be easily disassembled.

When installing a concrete rooftop waterproofing autonomous exhaust system between the surface of the rooftop (R) and the waterproofing layer (L), the main body hole drilled in the right place in the waterproofing layer (L) and the outer peripheral surface of the main body (10) that touches it are joined with adhesive. close the gap

When the rooftop (R) and the waterproof layer (L) are heated by sunlight, the moisture between them changes into water vapor and gas is generated through a hydration reaction. The water vapor and gas flow sideways through the gap between the surface of the rooftop (R) and the waterproof layer (L) and then flow into the bottom of the main exhaust hole (16) of the main body (10).

In FIG. 3, when the pressure of water vapor or gas in the main exhaust hole 16 rises and reaches a certain level, the valve 12 is pushed upward by the pressure and compresses the valve spring 13. Then, the moment the flange (18) leaves the flange seat (17), the water vapor and gas contained in the main exhaust hole (16) fall into the mooring space (a) and are discharged through the exhaust hole (19).

When the water vapor and gas pressure in the main exhaust hole 16 decreases due to the exhaustion of water vapor and gas, the valve 12 returns by the expansion pressure of the valve spring 13, and the flange 18 sits on the flange seat 17. Close the top of the main exhaust hole (16).

When the top of the main exhaust hole (16) is closed, even if the water level of the rainwater that has not been drained rises above the bottom of the exhaust hole (19), the rising amount of rainwater flows into the mooring space (a) through the exhaust hole (19). will be (see Figure 2).

However, when the flange seat 17 is blocked by the flange 18 of the valve 12, rainwater in the mooring space (a)) cannot flow back into the main exhaust hole 16.

When the level of rainwater on the roof falls below the bottom of the exhaust hole (19), the rainwater that has flowed back into the mooring space (a) flows out through the exhaust hole (19), and the exhaust function of water vapor and gas is revived.

In addition, if the drainage of the rooftop is not smooth and the pressure of water vapor increases even when the mooring space (a) is submerged in rainwater, water vapor and gas can be discharged through the main exhaust hole 16 due to the pressure difference.

Meanwhile, as the ground plate 11 is integrated into the bottom of the main body 10, there is no need to attach or fasten the ground plate 11 to the main body 10, and when the shade 20 is removed, the diaphragm 15 is exposed, so be careful. It can be easily separated from the main body (10) by pulling it over the thread.

After installation, when replacement or repair is required among the valve (12), valve spring (13), or spring pad (14), remove the cap (20), separate the diaphragm (15), and remove the spring pad (14). Even the spring (13) can be separated from the main body (10), and the valve (12) can also be removed. Therefore, parts to be repaired or replaced can be easily repaired or replaced. In addition, the main body 10 and the partition 15 are also non-fastening, making assembly and disassembly easy.

The strength of the present invention is that the mutual assembly process of the simple structure of the ground plate 11 and the body 10 is omitted, and the body 10 and the diaphragm 15 are also non-fastening, making assembly and disassembly easy.

In the concrete rooftop waterproofing autonomous exhaust system installed on the rooftop, the plurality of upward-emitting LEDs (22) arranged around the solar cell (21) provide very clear and bright LED light compared to a single downward-emitting LED. As a result, the rooftop nighttime decorative lighting is excellent even on foggy nights.

The above has been explained based on the description and drawings of preferred embodiments of the present invention, but is not limited thereto, and as long as it is identical to the organic combination of the components essential to achieve the purpose sought by the present invention, additions may be added. It should be understood that addition of elements, change to equivalents, etc. are included in the technical spirit of the present invention.
