Description

Thick railing {PARAPET COPING}

The present invention relates to a railing railing installed on the rooftop railing of a building, and more specifically, to a railing railing with a non-caulking and non-welding structure that can prevent water leakage due to the use of sealant.

Typically, railings with a certain height are installed on the rooftop of a building for safety and aesthetics. And at the top of the railing, a thick band is installed to prevent corrosion and cracks caused by the inflow of rainwater and at the same time improve the aesthetics.

Conventionally, flat or half-pipe-shaped thick pipes were installed in succession along the rooftop railing of a building, and then sealant was filled between the thick pipes to form joints.

However, when exposed to ultraviolet rays for a long period of time, the sealant forming the joint hardens and cracks occur, which causes rainwater leakage and requires continuous repair.

In addition, when the sealant forming the joint is used for a long period of time, the oil contained in the sealant leaks to the outside, and dust in the air and/or foreign substances mixed with rainwater easily settle, contaminating the exterior wall of the building.

In order to solve this problem, a two-geup band was developed that connects thick panels using geomeol folding without using a sealant.

That is, after forming a first locking piece bent clockwise downward on one side of the longitudinal panel of the thick panel and forming a second locking piece bent clockwise upward on the other longitudinal side of the thick panel, the first locking piece and The second hanging piece was connected to construct a double beam.

However, in the case of thick panels using geomeol folding, the area connecting the first and second locking pieces overlapped in several layers, so there was a problem of a step occurring between the thick panels.

As shown in Figures 1 and 2, the handrail thicker 10 according to an embodiment of the present invention is a non-caulking and non-welding structure that can prevent water leakage due to hardening and cracking due to the use of sealant. , It is composed of a thick panel 100, a thick drain joint 200, a bracket 300, a profile 400, and a drain angle 500.

Meanwhile, the handrail (E) on which the handrail thicker 10 of the present embodiment is installed is a handrail provided on the roof of a building, and more specifically, a finishing material (EC) is installed on the front to create a beautiful appearance of the building. It could be a railing (E).

The thick panel 100 is a metal panel that protects the handrail (E), that is, the handrail (hereinafter referred to as 'handrail') including the finishing material (EC). These thick panels 100 are rectangular plates extending in one direction and are continuously installed at regular intervals along the handrail E.

The thick panel 100 of this embodiment can completely cover the upper surface of the handrail E, and can also partially cover the front and back of the handrail E, that is, the longitudinal and width direction ends 110 and 120 are bent. has the form

As shown in Figure 3, the longitudinal end 110 of the thick panel 100 is bent downward to have an approximately 'L' shape, and when the thick panel 100 is installed, the thick drain joint 200, which will be described later, is formed. It is seated on the rib 230 of.

In addition, the width direction end portion 120 of the thick panel 100 is bent downward and then bent upward once more to have an approximately '√' shape, and when the thick panel 100 is installed, the vertical end of the profile 400 is Member 420 is fitted.

The above-described thick panel 100 may be manufactured from various metal materials. For example, it may be made of materials such as iron, copper, aluminum, and stainless steel. At this time, the thickness of the thick panel 100 is preferably 0.5 to 3.0 mm, but in the case of an aluminum composite panel, a thickness of 4.0 mm is also possible.

The thick drain joint 200 is a connector connecting two thick panels 100a and 100b installed adjacently, and is installed between the thick panels 100 successively installed along the handrail E.

In addition to serving as a connector connecting the thick panels 100a and 100b, the thick drain joint 200 of the present embodiment also serves as a drain for discharging rainwater, and for this purpose, it includes a gutter 210 that can collect and drain rainwater. .

The gutter 210 is shaped like a half pipe with a square cross section extending in one direction. Flanges 220 for installing the profile 400 are provided on both outer walls of the gutter 210, and ribs 230 on which the longitudinal ends 110 of the thick panel 100 are seated are protruded on both inner walls. In addition, a protruding web 240 for coupling with the bracket 300 is provided at the bottom of the trough 210.

The above-mentioned thick drain joint 200 is installed in the width direction of the handrail (E), but can be installed tilted toward the front (outside of the building) or rear (inside of the building) of the handrail (E) to drain rainwater. .

In particular, if the thick drain joint 200 is installed at an angle to the rear of the handrail E (inside the building), rainwater is discharged to the inside of the building (rooftop side) and the exterior of the building is exposed to rainwater (foreign substances contained in the rainwater). It can prevent contamination by

The bracket 300 is a fixture that secures the thick drain joint 200 to the railing (E) of the building. The bracket 300 has an angle shape bent at a right angle, one end (horizontal side) is fixed to the railing (E) of the building, and the other end is hinged to the drain joint 200.

For example, one end (horizontal side) of the bracket 300 may be fixed to the railing (E) of the building through anchoring, etc., and the other end (vertical side) may be fixed to a thick drain joint (200) through bolts and nuts (not shown). ) can be hinged with the web 240.

The profile 400 is for installing the thick panel 100 and consists of a horizontal member 410 mounted on the flange 220 and a vertical member 420 into which the thick panel 100 is inserted.

The profiles 400 are composed of a pair installed opposite each other, and are installed at both ends of the thick drain joint 200, respectively. At this time, the horizontal member 410 of the profile 400 mounted on the flange 220 of the thick drain joint 200 is fixed with a screw (not shown) or the like.

The drain angle 500 is provided at the thick drain joint 200 to induce the discharge of rainwater. The drain angle 500 is a pipe of square cross-section with an open top, and is bent into an 'ㄱ' shape so that it can be installed at the end of the thick drain joint 200. And one end of it is fixed by being inserted between the bottom of the gutter 210 and the rib 230 of the thick drain joint 200.

Meanwhile, the thick drain joint 200 and the drain angle 500 are preferably manufactured to have a constant cross-sectional area so that rainwater can be smoothly discharged. In other words, the rainwater discharge stability for the cross-sectional area of the drain joint 200 and the drain angle 500 can be examined through the allowable flow rate (Qa) and the rainwater discharge rate (Q).

First, the stability of the cross-sectional area of the drain joint 200, and more specifically, the gutter 210 provided in the drain joint 200, is as follows.

Thick panels 100 are installed at intervals (G) of 10 mm, the cross-section (W * H) and length (L) of the gutter 210 are 18 mm * 20 mm and 500 mm, respectively, and the roughness coefficient of the gutter 210 (n) ) is 0.013, and assuming that the gradient (I) of the gutter 210 is 3%,

The assumed superior cross-sectional area (Ag) of the gutter 210 is 70% of the actual height of the gutter 210 in consideration of stability,

Ag = W * H'= 0.018m * 0.014mm = 0.000252m ² ,

The edge of the gutter 210 (P: the length of the wall in contact with water in the cross section of the gutter 210) is,

P = W + 2H'= 0.018m + 0.028m = 0.046m,

The radius (R, hydraulic radius) of the gutter 210 is,

R = Ag / P = 0.000252m ² / 0.046m = 0.0055m.

When calculating the allowable flow rate (Qa) of the gutter 210 by substituting the values calculated through the above-described process into the Ganguillet Kutter formula,

The flow rate (V) of the gutter 210 is,

ego,

The allowable flow rate (Qa) of the gutter 210 is,

Qa(m3/sec) = Ag * V = 0.000252 m ² * 0.254m/sec = 0.000064m ³ /sec.

Meanwhile, the amount of rainwater runoff (Q) from the gutter 210 can be calculated using the maximum rainfall per second (IR) and the area exposed to rainfall (A).

In other words, if the maximum rainfall per hour is 145mm/hr (the maximum rainfall per hour recorded in Dongjak-gu, Seoul in August 2022),

The maximum rainfall per second (IR) is,

IR = 0.145m/hr * 1.5 (safety factor) / 3,600sec = 0.000060556m/sec,

The area (A) exposed to rainfall is,

A = G * L = 0.01m * 0.50m = 0.005m ² .

Therefore, stormwater runoff (Q) is

Q = IR * A = 0.000060556m/sec * 0.005 m ² = 0.000000303m ³ /sec.

By comparing the allowable flow rate (Qa) and stormwater runoff volume (Q) calculated through the above-described process,

Qa / Q = 0.000064m ³ /sec / 0.000000303m ³ /sec = 211.28,

Since the allowable flow rate (Qa) exceeds the stormwater outflow rate (Q), it can be confirmed that it is very safe when the cross-sectional area of the gutter 210 of the thick drain joint 200 is 20 mm x 10 mm (W x H).

The stability of the drain angle 500 can also be examined using the same method as described above.

The cross section (W * H) and length (L) of the drain angle 500 are 10 mm * 9 mm and 100 mm, respectively, the roughness coefficient (n) of the drain angle 500 is 0.013, and the gradient (I ) is assumed to be 3%,

The assumed superior cross-sectional area (Ag) of the drain angle 500 is 70% of the actual height of the drain angle 500 in consideration of stability.

Ag = W * H'= 0.01mm * 0.006mm = 0.00006m ² ,

The contour of the drain angle 500 (P: the length of the wall in contact with water in the cross section of the drain angle 500) is,

P = W + 2H'= 0.01m + 0.012m = 0.022m,

The radius (R, hydraulic radius) of the drain angle 500 is,

R = Ag / P = 0.00006m ² / 0.022m = 0.0027m.

When calculating the allowable flow rate (Qa) of the drain angle 500 by substituting the values calculated through the above-described process into the Ganguillet Kutter formula,

The flow rate (V) of the drain angle 500 is,

ego,

The allowable flow rate (Qa) of the drain angle 500 is,

Qa(m3/sec) = Ag * V = 0.00006m ² * 0.1342m/sec = 0.0000081m ³ /sec.

Meanwhile, the storm water discharge amount (Q) of the drain angle 500 can be calculated using the maximum rainfall per second (IR) and the area exposed to rainfall (A).

In other words, if the maximum rainfall per hour is 145mm/hr (the maximum rainfall per hour recorded in Dongjak-gu, Seoul in August 2022),

The maximum rainfall per second (IR) is,

IR = 0.145m/hr * 1.5 (safety factor) / 3,600sec = 0.000060556m/sec,

The area (A) exposed to rainfall is,

A = G * L = 0.01m * 0.10m = 0.001m ² .

Therefore, storm water runoff (Q) is

Q = IR * A = 0.000060556m/sec * 0.001m ² = 0.000000061m ³ /sec.

By comparing the allowable flow rate (Qa) and stormwater runoff volume (Q) calculated through the above-described process,

Qa / Q = 0.0000081m ³ /sec / 0.000000061m ³ /sec = 132.97,

Since the allowable flow rate (Qa) exceeds the stormwater outflow rate (Q), it can be confirmed that it is very safe when the cross-sectional area of the drain angle 500 is 10 mm x 9 mm (W x H).

Once the installation of the bracket 300 is completed, the thick drain joint 200 is coupled to the bracket 300 fixed to the railing (E) of the building. At this time, after the thick drain joint 200 is hinged to the bracket 300 using bolts and nuts (not shown), the slope (I) of the gutter 210 is adjusted to the rear of the handrail (E) so that it is 3%. Install it tilted toward the inside (see Figure 6).

Once the installation of the thick drain joint 200 is completed, the drain angle 500 is installed. At this time, the drain angle 500 is installed at one end of the thick drain joint 200, that is, at one end of the front side (outside of the building) of the handrail E, and the bottom of the gutter 210 of the thick drain joint 200 and the rib ( 230) and secure it (see Figure 7).

Once installation of the drain angle 500 is completed, the profile 400 is installed. At this time, the two profiles 400 are installed on both ends of the thick drain joint 200 so that they face each other, and then fixed using screws (not shown), etc. (see FIG. 8).

Finally, install the thick panel 100. At this time, while the longitudinal end 110 of the thick panel 100 is seated on the rib 230 of the thick drain joint 200, the widthwise end 120 of the thick panel 100 is perpendicular to the profile 400. It is installed to surround the member 420 (see Figure 9).

As described above, the railing 10 according to the present embodiment is provided with a thick drain joint 200 between the thick panels 100 installed along the railing E of the building to prevent the inflow of rainwater without using a sealant. can be prevented.

Therefore, not only can water leaks due to hardening and cracking caused by the use of a conventional sealant be prevented, but also the level difference between the thick panels 100 due to folding can be eliminated, creating an attractive appearance.

In addition, in the handrail thicker 10 according to this embodiment, the thick drain joint 200 is hinged to the bracket 300 through bolts and nuts (not shown), and the profile 400 is connected to the bracket 300 using screws (not shown). It is fixed to the thick drain joint 200 through a thick drain joint 200, and is a non-caulking and non-welding structure in which the thick panel 100 is inserted and joined to the profile 400. There is no risk of fire during construction, and repair and re-construction are easy.

As described above, the present invention has been described with reference to the illustrative drawings, but the present invention is not limited to the embodiments and drawings disclosed herein, and various modifications may be made by those skilled in the art within the scope of the technical idea of the present invention. It is obvious that transformation can occur. In addition, although the operational effects according to the configuration of the present invention were not explicitly described and explained while explaining the embodiments of the present invention above, it is natural that the predictable effects due to the configuration should also be recognized.
