Description

Steel-based roof waterproof assembly with enhanced drainage function

The present invention relates to a steel-based roof waterproofing assembly with a reinforced drainage function, and more particularly, by extending the drip tray installed between the roofs of the inclined structure made of steel material in the downward direction in the direction of gravity toward the drain port of the roof slab. It relates to a roof waterproofing assembly that can enhance drainage while preventing water from accumulating.

Roofs are often made of plate-shaped slabs, and as rainwater, snow, moisture, etc. penetrate into the slab, water leakage may occur in the building.

Various methods of waterproofing construction are known, such as coating waterproofing, sheet waterproofing, and composite waterproofing, which is a mixture of coating waterproofing and sheet waterproofing. Accordingly, there was a disadvantage in that the problem of water leakage due to cracks in the waterproofing layer occurred again, and the maintenance cost of the building was increased due to the need for periodic maintenance.

To solve this problem, waterproofing with metal, especially steel, provides the advantage of being able to see a neat interior effect while being less affected by the external environment.

5 is a conceptual diagram illustrating a known roof steel waterproof structure, and FIG. 6 is a perspective view of FIG. 5 .

5 and 6 show the structure of the roof steel waterproofing system, which is the applicant's Korean Patent No. 1630151, and the structure will be briefly described as follows.

The steel roof waterproofing system according to FIGS. 5 and 6 includes a roof 30 (a) and 30 (b), a drip tray 110 , a support, an inner wall cover 120 and a handrail cover 140 .

First, the roofs 30 (a) and 30 (b) are formed to be inclined upward, respectively, in the direction of the handrails 20 located on both sides of the roof with respect to the center of the surface of the slab 10. Specifically, it is made of a plate-shaped steel material. It is made up of a plurality of steel panel combinations. At this time, the roofs 30(a), 30(b) are divided into a first roof 30(a) on the left and a second roof 30(b) on the right based on the center of FIG. 5, and now 1 and 2 roofs 30(a) and 30(b) take a symmetrical or symmetrical structure with respect to the gutter 110 located in the center thereof.

At this time, the points where the first and second roofs 30(a) and 30(b) meet are spaced apart by a certain length, and the water gutter 110 is installed along this spaced portion so that the first and second roofs 30(a), 30(b), 30(b)) is hermetically connected. A drain hole is formed through one side of the drip tray 110, and the water discharged from the drain hole is connected to the drain hole 11 formed on one side of the slab.

In addition, based on the structure in which the through hole is formed, a foreign material cover that drops moisture, such as rainwater, to the drip tray side through the through hole, but filters foreign substances having a particle size larger than moisture, may be mounted on the upper portion of the drip tray 110 .

A plurality of supports standing between the slab 10 and the roof 30(a), 30(b) have a bar shape, and the first and second roofs 30(a), 30(b)) While having a length corresponding to the inclined structure of ) is a plurality of structures supporting Such a support can be made of a structure such as a ladder by inserting a support between each frame so as to form a plate shape, a bar shape, an upper and a lower frame having a certain thickness, and the like, and this structure is provided with the necessary strength or strength after the construction of the roof. Depending on the durability, the builder can freely choose.

The outer ends of the first and second roofs 30 (a), 30 (b) and the handrail 20 can be connected while being sealed with the inner wall cover 120 and the handrail cover 140 as a medium, and the inner wall cover 120 covers the inner side of the handrail 20 , and the handrail cover 140 serves to cover the upper surface of the handrail 20 .

According to the composite structure of the steel roof, it provides excellent roof waterproofing and excellent durability due to the steel material that reliably prevents moisture penetration, and provides a characteristic that can boast a neat appearance.

However, according to the above technology, since the drip tray 110 extends a considerable length in a direction perpendicular to the left and right direction of the roof, that is, along the width direction of the roof, when the drip tray 110 is extended in a state parallel to the slab 10, this The water accumulated in the drip tray 110 may not be smoothly discharged to the drain hole, and there may be a problem that the water accumulates.

Therefore, there is a need to develop a new and advanced steel roof-based roof-based waterproofing assembly based on the above-described roof steel structure, but which does not collect water in the gutter and can more reliably strengthen the drainage function.

The present invention has been devised to overcome the problems of the above technology, and in a steel roof structure including a steel roof inclined upward in the left and right outward directions based on the gutter extending in the width direction of the slab, the gutter is parallel to the slab Rather than extending, the drainage hole is formed on one side close to the drain hole of the slab, and the structure is extended downwardly toward the drain hole to prevent water from accumulating in the gutter, and a roof waterproofing assembly that can drain into the drain hole more reliably Its main purpose is to provide

Another object of the present invention is to prevent the phenomenon of water accumulating on the bottom surface of the drip tray by extending the bottom surface of the drip tray to be inclined downward toward the center without making it into a flat structure.

Another object of the present invention is to install a drainage passage connecting the drain hole and the drain hole of the drip tray when the drain hole is away from the drip tray, but also to install the drainage passage inclined downward toward the drain hole to prevent water from accumulating.

A further object of the present invention is to laminate a reinforcing coating layer on the bottom surface of the drip tray to prevent moisture from forming due to condensation on the bottom surface of the drip tray.

In order to achieve the above object, a steel-based roof waterproofing assembly with a reinforced drainage function according to the present invention includes a drip tray extending along the width direction of the slab from the central portion of the slab on the roof, and located at both left and right side ends of the roof in the drip tray In a state including a waterproof structure including a steel roof formed to be inclined upward toward the handrail, the gutter extends downward to a point facing the drain formed on one side of the slab, and the drain hole on one side close to the drain hole It is characterized in that it is formed through.

In addition, the bottom surface of the drip tray is characterized in that it extends downward from the lower end of each side of the drip tray toward the center of the bottom surface of the drip tray.

In addition, in the roof waterproofing assembly, a drainage passage connecting the drainage hole and the drainage hole is installed, and the drainage passage is characterized in that it extends downwardly from the drainage hole to the drain hole.

According to the steel-based roof waterproofing assembly with enhanced drainage function according to the present invention,

1) It is possible to strengthen the function of draining water through the drain while preventing water from accumulating in the gutter by extending the gutter with a characteristic that is not short along the width direction of the slab in a downward slope in the direction of the drain.

Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings. The accompanying drawings are not drawn to scale, and like reference numbers in each drawing refer to like elements.

The roof waterproofing assembly according to the present invention is based on including the steel-based waterproofing structure of FIGS. 5 and 6 described in the background art.

That is, the roof waterproofing assembly of the present invention is mainly characterized in that the drip tray 110 is improved in particular in the waterproof structure of the above-described known technology. A description of a separate structure and function of the configuration will be omitted and the drip tray 110 will be mainly described.

1 is a schematic structural and partially enlarged perspective view of a roof waterproofing assembly of the present invention.

As mentioned above, the roof waterproofing assembly of the present invention is based on including the basic configuration of the background art, that is, the roof waterproofing assembly of the present invention is formed extending along the width direction of the slab 10 from the central portion of the slab 10 of the roof. A water-repellent structure including a water gutter 110 and a steel roof (30(a), 30(b)) formed to be inclined upwardly toward the handrail 20 located at the left and right side ends of the roof in this gutter 110. do it by default

As can be seen from the partially enlarged view of FIG. 1 , the drip tray 110 of the present invention extends downward to a point toward the drain hole formed on one side of the slab 10, and in a state in which it extends downwardly, the drain hole (Fig. 2, shown as '110') is characterized in that it is formed through.

Here, the 'downward slope' means that when it is said that the drip tray of the above-described background art extends in a parallel direction with the slab is extended in the horizontal direction, the known drip tray extending in the horizontal direction is formed on one side of the slab 10 It means that it is extended in a downward slope toward the drain hole. In this principle, the meaning of 'upward inclination' refers to a direction opposite to the above-described downward inclination direction.

In general, the gutter is the width direction of the roof or the slab 10 in the central portion of the waterproof structure or the central portion of the slab 10 (orthogonal to the extension direction of the roof extending left and right in FIG. 1 and extending in the front and rear of the roof) It extends along, the drain hole must not penetrate the central part of the roof/slab 10 or the central part of the roofs 30(a), 30(b), but on one side out of the center of the roof/slab 10 are often formed.

Therefore, the drip tray 110 of the present invention takes a downward-sloping structure with the goal of this drain port (illustrated as 11 exemplarily in FIG. 5) as the end point, that is, the drain hole ( 11), for example, it has a structure inclined in the downward direction in the direction of gravity to a point that touches a virtual water line extending from the drain 11 to the drip tray 110 .

The drain hole 111 is penetrated at the point where the drip tray 110 touches the above-described virtual water line, that is, the drain hole 111 is penetrated in the portion of the drip tray 110 closest to the drain hole 11 . The drain hole 111 and the drain hole 11 may be located at a point similar to each other without a separate spaced distance, but as mentioned above, the drain hole 111 and the drain hole 11 may be physically spaced apart due to various environments on the roof. Therefore, a separate pipe for connecting the drain hole 111 and the drain hole 11 without water leakage may be installed. This pipe will be separately described below.

To further explain the drip tray 110 , the drip tray 110 may take a single inclined structure or a bent inclined structure depending on the location of the drain hole 11 .

For example, when the drain 11 is penetrated on one side of the peripheral portion of the slab 10, the gutter 110 with a single slope (ie, a linear slope) as shown in FIG. 1 aiming at this point vicinity. It can be extended, and when the drain hole 11 is penetrated at the point that entered the center side rather than the peripheral portion of the slab 10, the drain hole 111 penetrated at a position close to this point from both side ends of the drip tray 110, respectively. It is also possible to extend downward obliquely and to be bent in a structure similar to the 'V' shape as a whole.

In addition, the drip tray 110 of the above-described downward sloping structure may extend the drip tray 110 itself made of a rectangular parallelepiped having a hollow inside in the direction of gravity, or the roof 30 (a) connected to the drip tray 110 , 30(b)) also need to adjust the angle, so the upper surface of the drip tray 110 takes a horizontal structure, but only the bottom surface of the drip tray 110 has a downwardly inclined structure according to the extension direction of the drip tray 110. ) can also be designed to have different heights.

In addition, the inclination angle of the drip tray 110, as shown in FIG. 1, is to be adjusted within the range of 1 to 5 degrees, due to the steep inclination, durability for the entire connection structure with the roof (30(a), 30(b)) It is desirable to avoid falling.

According to this drip tray 110, considering that the width of the roof is usually extended for a long distance rather than a short distance such as 1,2 meters, water in a known state in which the drip tray 110 is horizontally extended. It can prevent the problem of stagnant water not draining smoothly.

In other words, the drip tray 110 of the present invention takes a structure inclined downward toward the gravity direction toward the drain hole 11 and the drain hole 111, and the water accumulates in the drip tray 110 extending long in the width direction of the roof for maintenance. Provides features that enhance drainage while avoiding troublesome problems with

Figure 2 is a longitudinal cross-sectional view showing the connection structure of the gutter and the drain according to the present invention.

First, referring to the structure of the drip tray 110 itself in Fig. 2(a), it can be seen that the bottom surface (bottom surface) of the drip tray 110 is not formed in a flat structure but has a pointed structure toward the center of the bottom surface.

In other words, the bottom surface of the drip tray 110, based on FIG. 2 (a), from the lower end of each of the left and right sides of the drip tray 110, it is possible to take a structure that extends downward toward the center of the bottom surface of the drip tray 110. .

Accordingly, the bottom surface of the drip tray 110 with a reinforced drainage function is improved to a V-shaped cross-sectional shape, thereby providing a basis for implementing an excellent drainage function without accumulating water in the drip tray 110 .

Also, as mentioned above, the drain hole 111 of the drip tray 110 and the drain hole 11 of the slab 10 do not necessarily converge at the same location and may be spaced apart from each other by a certain distance. As can be seen from 2 (b), it is possible to include a drain 112 connecting the drain hole 111 and the drain hole 11 while preventing water leakage.

This drain 112 extends downward from the drain hole 111 on the drip tray 110 side to the drain hole 11 on the slab 10 side. ) can reliably prevent water from accumulating in the hollow formed inside.

Figure 3 is a longitudinal cross-sectional view showing a supporter for supporting the drip tray of the present invention.

As described above, when the drip tray 110 is extended to be inclined downward, a kind of distortion occurs in the overall structure of the roof waterproofing assembly of the present invention, and the drip tray 110 sags in the direction of gravity or the roof 30 (a) connected to the drip tray 110 , 30(b)) may cause problems such as bending due to increased fatigue on one side.

In order to prevent this problem, as can be seen from FIG. 3 , a plurality of supporters 113 are installed standing up at a predetermined interval along the width direction of the roof between the bottom surface of the drip tray 110 and the surface of the slab 10 . possible.

As a result, the supporter 113 stably supports the drip tray 110, similar to the principle that the support of the background art supports the roof 30 (a), 30 (b), so that the drip tray 110 moves in the direction of gravity over time. It provides properties that prevent sagging problems.

The drip tray 110 of the present invention is preferably made of a steel material like the roofs 30 (a) and 30 (b) in order to ensure durability and provide a waterproof function. (110) A temperature difference may occur between the inside and the bottom surface of the drip tray 110 at the bottom thereof, and especially in winter or summer, condensation occurs on the bottom surface (outside of the bottom surface, not inside) of the drip tray 110 due to such a temperature difference There is a probability that water may fall to the slab 10 side due to this occurrence. If this phenomenon persists, unnecessary water is not easily absorbed in the slab 10 under the drip tray 110, which may adversely affect the waterproof function of the assembly of the present invention.

In order to solve this problem, in the present invention, an embodiment of coating or laminating a reinforcing coating layer on the lower surface of the drip tray 110 is further provided.

Specifically, the reinforcing coating layer of the present invention includes a coating film strengthening agent including vinyl acetate-butyl acrylate copolymer, that is, a gel-like or liquid coating film strengthening agent on the bottom side of the drip tray 110 . A reinforcing coating layer can be laminated by applying it to the surface and curing it.

At this time, the vinyl acetate-butyl acrylate copolymer, which is the main material of the coating film strengthening agent, not only improves adhesion to the bottom surface of the drip tray made of a metal material such as steel, but also adds heat resistance to the temperature difference with the inside of the drip tray 110 through which water flows. It provides a characteristic of preventing the problem of water remaining around this by reducing the dew condensation on the bottom surface of the drip tray 110 by reducing the.

Furthermore, the coating film strengthening agent may further include not only the vinyl acetate-butyl acrylate copolymer but also additional other components, which will be described with reference to the drawings as follows.

4 is a flowchart illustrating the steps of preparing the coating film strengthening agent of the present invention.

4, the coating film strengthening agent of the present invention is manufactured through the steps of preparing a primary solution (S31), preparing a secondary solution (S32), and completing the coating film strengthening agent (S33). characterized in that

As described above, the vinyl acetate-butyl acrylate copolymer provides a function of improving the mechanical strength of the reinforcing coating layer and improving adhesion to the bottom surface of the drip tray 110 as well as preventing dew condensation.

The styrene-maleic anhydride copolymer is a copolymer added to conventional architectural paints or cements, and is known to increase both toughness and rigidity of the reinforcing coating layer and exhibit excellent dispersibility.

Polyvinyl alcohol is added as a solvent for the primary solution, is thermoplastic and oil-resistant, and is also used as an adhesive and coating agent. Therefore, it is possible to dissolve the vinyl acetate-butyl acrylate copolymer and the styrene-maleic anhydride copolymer, and has an effect of increasing the adhesiveness of the reinforcing coating layer by itself.

Next, 75 to 90 parts by weight of the primary solution, 5 to 15 parts by weight of nitrocellulose, and 3 to 10 parts by weight of sodium magnesium silicate are mixed to prepare a secondary solution.

Nitrocellulose is also used as a material for plastics, inks, films, and wood coatings, and as a kind of film former, it exhibits durability, toughness, solubility and quick evaporation of solvents in a general dry environment.

Sodium Magnesium Silicate is a synthetic silicate clay composed of sodium silicate and magnesium, which acts as a bactericidal preservative and preservative. Therefore, it is added as a paint film reinforcing agent to improve the preservative performance of preventing physical properties from being deformed or decayed over time in the added reinforcing coating layer.

(S33) Step of completing the coating film strengthening agent

Finally, 70 to 80 parts by weight of the secondary solution, 1 to 10 parts by weight of Sodium Dodecyl Benzene Sulfonate, and 5 to 10 parts by weight of a flexibility modifier comprising Acetyl Tributyl Citrate The parts are mixed to complete the film strengthening agent.

Sodium dodecylbenzenesulfonate is a composition having a surfactant function, has high solubility, and serves to increase the miscibility of the above-described various compositions included in the coating film strengthening agent according to the addition thereof.

Acetyl tributyl citrate added as a softening agent is a film former, that is, a plasticizer added together with the addition of nitrocellulose as described above. Acetyl tributyl citrate is added to increase the elasticity of the reinforcing coating layer to maintain elasticity when heat conduction occurs in the steel drip tray, thereby enhancing the flexibility to prevent cracks or cracks.

Therefore, the coating film reinforcing agent including these various compositions not only increases the film strength, toughness, rigidity, and water tightness of the reinforcing coating layer, but also allows the film to be formed more evenly. can provide
