Description

Soundproof wall using polyurea-coated posts and its repair method {SOUNDPROOF WALL WITH POLYUREA-COATED COLUMN AND REPAIRING METHOD THEREOF}

The present invention relates to a soundproof wall and a repair method thereof using a polyurea-coated post, and more specifically, compared to a conventional galvanized H-type post, while making it advantageous for contamination and maintenance, a soundproof panel laminated between H-type posts By effectively preventing the transfer of the load to the soundproof panel installed at the bottom, but using a polyurea-coated post that can simply repair the soundproof wall including the post using polyurea or UV coating material. It relates to soundproof walls and their repair methods.

In recent years, according to rapid industrial development, the diversification of transportation means and the amount of traffic are increasing, and the roads, railroads, and airports on which these means of transportation travel have been expanded. As a result, residents living around roads, railroads, and airports are suffering from the noise generated by transportation.

Therefore, when designing roads, railroads, and airports, noise standards below a certain limit are strictly applied, and various types of soundproof walls, for example, sound-absorbing type, reflective type, interference type, resonance type, etc. Soundproof walls are installed.

These soundproof walls are installed so that noise generated from vehicles in the vicinity of a road or railroad on which the vehicle is traveling is not transmitted to buildings such as houses, schools, etc. adjacent to the road.

Specifically, the sound insulation wall according to the prior art has a plurality of "H"-shaped posts installed along the length direction of the road on both sides of the road, and both ends are slide-fitted between these posts, and a sound absorbing material for noise absorption is provided inside. It is composed of a soundproof panel, which is a frame member, and at the time of installation, the posts are first fixed on both sides of the road at a predetermined distance along the length of the road, and both ends of the soundproof panel are aligned in the corresponding space between the posts. After that, it is installed in a manner of stacking and fixing by pushing one by one downward from the top of the post.

On the other hand, when installing such a soundproof wall, a post is installed so that it can be safely supported from wind pressure, and such a post uses a hot-dip galvanized post for the purpose of preventing corrosion.

Hot-dip galvanized struts (usually H-type struts) suffered from a problem of reduced durability due to driver's glare from sunlight reflection and rust after a certain period of time.

Such galvanizing is a method of plating by dipping a pre-heated iron product in molten metal zinc of 430 to 450°C and soaking it. After degreasing, acid treatment, drying, galvanizing, cooling, for example, a plating thickness of 77 μm or more, It is a method of processing to satisfy the quality of the zinc adhesion amount of 550g/㎡.

1A is an exemplary view showing a hot-dip galvanized support for a sound insulation wall according to the prior art.

That is, it can be confirmed that rust is generated on the hot-dip galvanized pillar of the conventional sound insulation wall.

As shown in Fig. 1A, the galvanized strut of the sound insulation wall according to the prior art is used as H-type steel and galvanized. However, there is a problem in that the plated zinc is peeled or cracked due to the external environment such as ultraviolet rays or acid rain, and thus, corrosion proceeds and durability is gradually reduced.

In addition, when the plating temperature is high, black color is generated, which impairs the appearance, and plating defects may occur when the slag is not removed from the welding part.In particular, the hot-dip galvanized struts become a factor in the operation obstruction by glare due to sunlight reflection.

Accordingly, when a defect occurs in the conventional hot-dip galvanized pillar, temporary repairs are made with silver powder, making it impossible to restore the original state.

Figure 1b shows an exemplary view of a conventional sound barrier load transfer prevention device 50.

Since the soundproof wall uses H-type steel frame as the post 10, both sides of the soundproof panel frame 30 wrapped around the outer circumferential surface of the soundproof panel P are inserted and installed between the flanges of the H-shaped steel frame spaced apart from each other. It can be seen that the soundproof wall is constructed by stacking a plurality of soundproof panel frames 30 up and down.

Accordingly, the soundproof panel frame 30b located at the bottom may cause deformation and damage as the weight of the soundproof panel frame 30 located at the top is transferred as it is.

Accordingly, in FIG. 1B, a load transfer prevention device 50 of a method of fixing each soundproof panel frame 30 to the support 10 is used to connect the corners of the support 10 and the soundproof panel frame 30. You can see that there is.

Accordingly, since the self-weight of each soundproof panel frame 30 is constrained to the post 10 by the load transfer prevention device 50, it is possible to prevent the phenomenon that the load is concentrated on the lower soundproof panel frame 30.

However, the load transfer prevention device 50 for constraining the soundproof panel frame 30 to the post 10 has a complicated structure and is not easy to manufacture, and when the number of installations increases, the workability and economy are inevitably lowered.

Figure 1c shows an exemplary view of another conventional sound barrier load transfer prevention device.

It is understood that such a load transfer prevention device inserts the wedge frame (2) in the area where the bottom surface and the top surface of the soundproof panel frame (30) contact, and installs a horizontal support bolt (3) so that the wedge frame (2) does not fall off. I can.

However, it can be seen that such a wedge frame 20 is not only uneconomical but also has a limitation that it may be somewhat vulnerable to impact when it is formed in accordance with the entire length of the bottom and top of the soundproof panel frame 30.

[Soundproof wall 100 using polyurea-coated posts]

2A, 2B, 2C, 2D, 2E, and 2F are perspective views and exemplary views of a polyurea coating of a soundproof wall 100 using a post coated with polyurea of the present invention.

The soundproof wall 100 using a polyurea-coated post of the present invention first coats the post 120 with polyurea, and uses the load support device 140 on the post coated with polyurea to facilitate replacement and repair. Is done.

Thus, first looking at the posts 120 coated with polyurea are as follows.

In the case of a conventional soundproof wall, the posts 120 are installed, and a soundproof panel is positioned between the posts. Particularly, since the strut 120 of the soundproof wall is exposed to air, rust occurs due to snow, rain, dew, etc., so that the strut, bracket, lower plate, or fastening bolt is galvanized and installed.

However, as time passes, rust is generated due to the peeling of the coated zinc plating, which is a problem, and maintenance is difficult.

In other words, in order to maintain the strut, bracket, lower plate or fastening bolt during maintenance of the soundproof wall where rust has occurred, the soundproof panel must be disassembled and separated to secure a working space.

If the post 120 and the soundproof panel are galvanized, it may be good in terms of aesthetics,

Galvanization can cause damage to the driver due to glare caused by light, and if rust occurs on the soundproof panel, maintenance must be performed by separating and dismantling and replacing it, which is a problem that requires a lot of cost and time. There will be.

Accordingly, the present invention does not coat the posts with zinc plating, but coats them with polyurea.

According to FIG. 2A it can be seen that the support 120 is coated with polyurea.

As such, the polyurea used for the post 120 has good compressive strength, elasticity, acid resistance, alkali resistance, chemical resistance, and resistance to UV rays, and has no environmental pollution and is not affected by temperature at all. There is also an advantage that can be constructed.

As such a waterproofing agent, it is preferable that the coating thickness of polyurea is approximately 500 μm or more, and it can be seen that workability can be secured by applying it quickly.

Specifically, the strut 120 of the soundproof wall 100 is formed by spraying a polyurea-coated waterproofing agent to a predetermined thickness in a conventional H-type steel material without galvanizing or in a galvanized state.

Such polyurea can secure a function as a waterproofing agent, and is strong against ultraviolet rays, which is advantageous for maintenance.

In addition, as shown in FIG. 2A, polyurea is a polymer produced through a chain reaction of amine having an active amine group (-NH2) and isocyanate having isocyanate guoup (-NCO), and the reaction rate of urea resin It is an ultra-fast curing material that is very fast. It is a two-component (subject + hardener) coating agent of high temperature and high pressure spray method, is harmless to the human body, and has the advantage of having abrasion resistance, chemical resistance, and impact resistance.

Therefore, the sound insulation wall 100 according to the embodiment of the present invention,

It prevents rust by coating and waterproofing by coating and waterproofing subsidiary materials such as the pillar 120, the lower plate and the panel fixing plate, rather than galvanizing, and polyurea, a waterproofing agent, coated without the need for separate separation during subsequent maintenance. The maintenance cost can be minimized by applying only.

In addition, since the polyurea coating of the present invention can be UV coated with different colors as shown in FIG. 2B, glare does not occur, and soundproof panels as well as posts can be produced in various colors when constructing a soundproof wall. It can be seen that it is very effective.

Accordingly, a primer is applied to the posts 120 to ensure flatness and adhesion, and after applying polyurea, the final UV coating material is used.

At this time, looking at the process of coating the polyurea in detail,

After cleaning the surface of the posts and blasting, apply a primer (adhesive), and then coat the polyurea using a polyurea-specific coating equipment, and measure the thickness of the coated polyurea film. It is preferable that the thickness of the urea-coated coating film is formed to be at least 500 μm.

At this time, blasting is performed to cleanly clean the steel surface and improve the adhesion between the coating agent and the steel surface. For example, a shot ball is used to blast the surface of a steel material using a shot machine.

Accordingly, when a primer (adhesive) is applied to the post 120, as a process for improving the adhesion of the polyurea, for example, a two-component primer for iron may be used.

In addition, as shown in Figure 2c, using a coating equipment dedicated to polyurea is coated with the primer 120 is applied.

This polyurea coating has excellent durability and mechanical properties, and a dedicated coating equipment capable of discharging a 1:1 ratio is used.

For example, including a supply pump (Supply Pump), agitator (Agitator Kit), a reactor (Reactor), a heating hose and a spray gun (Fusion Spray Gun) to coat the polyurea on the post 120 Polyurea coating is performed using a coating equipment exclusively for polyurea.

According to FIGS. 2D, 2E and 2F, the effects of the durability, chemical resistance, and attachment force evaluation test of the polyurea-coated support 120 can be confirmed.

That is, as shown in Fig. 2d, it can be seen that the polyurea-coated support 120 of the present invention is not discolored, lifted or rusted even after 3, 6, 12 months elapsed, so that durability can be confirmed,

In addition, as shown in Fig.2e, a polyurea-coated steel material, a hot-dip galvanized steel material, a section steel, a molten zinc-plated steel material, and a polyurea-coated section steel were immersed in a 10% calcium chloride solution for 6 months. In the case, it was confirmed that there was almost no difference in wrinkles, cracks, swelling, peeling, and gloss.

In addition, as shown in Figure 2f, after attaching the metal dolly to the polyurea-coated posts 120 using a strong adhesive (primer), the maximum load required for separation was measured. As it can be confirmed, it was also confirmed that various accessory materials can be attached to the surface of the polyurea-coated post 120.

Next, looking at the sound insulation wall using the load support device 140 for easy replacement and repair by using the load support device 140 on the post coated with polyurea are as follows.

3A, 3B, and 3C are perspective views and perspective views of the soundproof wall 100 using the load supporting device 140 of the present invention.

Soundproof wall 100 using such a load supporting device 140 is installed so as to be spaced apart from each other on the support 120 coated with polyurea on the soundproof wall base 110,

In the stacking and installation of the soundproof panel 130 up and down between the posts 120, a load support device 140 is installed between the bottom surface of the upper soundproof panel 130b and the upper surface of the lower soundproof panel 130a,

Through the connection bar 150 through the end bolt groove 141 of the load support device 140,

By adjusting the length of the connection bar 150, the position of the soundproof panel is fixed and the load transferred to the lower soundproof panel 130a is reduced.

Accordingly, the soundproof wall 100 using the load supporting device 140 is a soundproof wall base 110, a post 120, a soundproof panel 130, a load supporting device 140, as shown in FIGS. 3A, 3B and 3C, It includes a connection bar 150.

First, the soundproof wall base 110 is as shown in FIG. 3A,

As a concrete member for fixing the lower end of the post 120 coated with polyurea, it may be constructed as a continuous block having a certain height according to the extension length of the sound insulation wall 100, and is formed on the side of a road or bridge.

As shown in FIG. 3A, the post 120 uses an H-shaped steel frame installed vertically on the upper surface of the soundproof wall base 110, and a soundproof panel 130 is inserted between the abdomens of the posts 120 spaced apart from each other.

At this time, the gap between the two flanges of the posts 120 is formed larger than the thickness of the sound insulation panel 130, so that the sound insulation panel 130 is sandwiched between the posts 120, and the sound insulation panels 130 are stacked up and down. In order to prevent the load from being excessively transferred to the lower soundproof panel 130, the load support device 140 and the connection bar 150 of the present invention are used.

The soundproof panel 130 may be used without a frame as, for example, a rectangular transparent panel, as shown in FIG. 3A, and is stacked up and down between the abdomens of the posts 120 and installed.

Accordingly, in the lower soundproof panel 130a located at the bottom, since its own weight P is accumulated by the upper soundproof panel 130b located at the upper part, damage or deformation may occur over time.

Accordingly, in the present invention, the load supporting device 140 is disposed over the entire length of the upper and lower surfaces of the soundproof panel 130.

The load supporting device 140 is a strip member made of an elastic material extending to have a predetermined thickness and length, as shown in FIGS. 3A and 3B.

By having a predetermined elasticity, some of the loads due to the upper and lower stacking of the soundproof panel 130 are absorbed, and the load is effectively transmitted to the soundproof panel 130 located below.

That is, since the load supporting device 140 is set over the entire extended length (L) of the bottom and top surfaces of the soundproof panel 130, it has a very advantageous shape for absorbing and transmitting load and has elasticity, so the soundproof panel 130 is laminated. At the time, it is possible to prevent damage due to the impact applied to the upper and lower surfaces, and when separated from the support 120 and the soundproof panel 130, it also plays a role of facilitating replacement of the soundproof panel 130 by the occupied space. .

Accordingly, according to FIG. 3B, end bolt grooves 141 and corner block-out portions 142 are formed on both end surfaces A of the load supporting device 140.

Accordingly, since the connection bar 150 is not directly installed through both ends of the load support device 140, a soundproof panel is provided by using the connection bar 150 to the post 120 without damaging the load support device 140. It is possible to simply fix and install (130) to the post (120).

Accordingly, it can be seen that the end bolt groove 141 and the corner block-out part 142 are for simply fixing and installing the load supporting device 140 to the post 120 using the connection bar 150.

Accordingly, the corner block-out portion 142 is a space formed by blocking out both end edges of the load supporting device 140 and serves to support while receiving the bolt head portion 151 of the connection bar 150.

The end bolt groove 141 is a horizontal slit groove formed in the center of the end surface of the strip member to set the position by inserting the connection bar 150 from the side.

Accordingly, while installing the body portion 152 of the connection bar 150 in a manner that is inserted into the end bolt groove 141, the bolt head portion 151 of the connection bar 150 is located inside the corner block-out portion 142 Will do.

At this time, since the corner block-out part 142 is formed at the end edge, the corner block-out part 142 is in communication with the end bolt groove 141, and the initial entrance of the end bolt groove 141 is a locking projection 143 ) Is formed so that the fitted connection bar 150 is not separated by impact or the like.

The connection bar 150 is installed by being inserted into the end bolt grooves 141 and corner block-out portions 142 formed on both end surfaces of the load support device 140, as shown in FIGS. 3B and 3C, and is soundproofed through length adjustment. It is a bolt for fixing the panel 130 to the post 120.

Accordingly, the connection bar 150 is formed to include a bolt head portion 151 and a body portion 152 as shown in FIG. 3B.

The body portion 152 is a bar member, and a bolt head portion 151 is integrally formed on one side thereof, and a bolt hole 153 extending inward from the other side thereof is formed.

Accordingly, as the fastening bolt 154 is rotated and fastened to the bolt hole 153, the extension length of the connecting bar 150 can be adjusted according to the fastening depth inserted into the bolt hole 153.

Accordingly, the bolt head portion 151 is inserted into the corner block-out portion 142 and is set to contact the inner side of the corner block-out portion 142, as shown in FIG. 3B, and the body portion 152 has an end bolt groove ( 141) is inserted laterally.

Thereby, while adjusting the fastening depth of the fastening bolt 154 to the bolt hole 153 on the other side of the body 152, the soundproof panel 130 is set to the post 120 while preventing the load support device 140 from being separated. You can do it.

At this time, the connection bar 150 is not used only for the function to prevent separation of the load support device 140 and the load transfer of the soundproof panel 130, but directly between the soundproof panel 130 and the post 120 It is installed and used for stable installation of the soundproof panel 130 through length adjustment.
