In one embodiment, the supporting frame 300 may include a body 310, a coupling unit 320, a glass fitting portion 330, a lighting substrate 340, and a lighting coupling portion 350.

The body 310 may be formed of a polycarbonate material extending in the longitudinal direction to have a thickness of 1 to 2 mm. The length of the body is the length between the first main frame 100 and the second main frame 200

Coupling units 320 are disposed at both ends to couple the first main frame 100 , the second main frame 200 and the support frame 300 and provide power to the lighting board 340 .

In the glass fitting part 330, the glass may be fitted and fixedly disposed. At this time, it goes without saying that the interval between the glass fittings 330 may be variously changed according to the type and thickness of the glass used.

The lighting board 340 is mounted on the body 310 and can irradiate LED lights upward and downward from the rear of the glass. Due to the irradiation of the lighting, it is possible to impart an excellent sense of aesthetics to the exterior of the building at night, and, of course, it is possible to implement an LED exterior lighting show if necessary.

The coupling rod 3223 may provide coupling force between the cover 3270 and the coupling member 3271 at one end of the central wall 3222 . More specifically, here, the coupling member 3271 may be a screw, and in the case of a screw, the coupling rod 3223 has a screw thread formed therein like an anchor so that it can be firmly coupled with the coupling member 3271. .

In one embodiment, the clearance providing unit 3230 may include a fixed body 3231, a two-stage molded body 3232, an extension body 3233, and a protruding coupling body 3234.

The fixture 3231 may be fitted and coupled to the fitting bent protrusion 32221 of the central wall 3222 and fixed by a screw in the fixture 3231.

The two-stage molded body 3232 may be formed by being firstly bent at an angle of 90° and secondarily bent at an angle of 45° at one end of the fixed body 3231 to be extended.

The reason for this two-stage bending is that the glass is later inserted into the glass fixing part 3260 and the protruding assembly 3234 combined with the glass fixing part 3260 is together when the glass flows due to wind, vibration, shock, etc. it gets moving

At this time, when there is wind, vibration, shock, etc., a space is formed in which the glass can move up and down to the coupling bar 3223 of the central coupling part 3220 due to the bent portion of the two-stage molded body 3232. may not be easily damaged. To this end, of course, the two-stage molded body 3232 may be formed of a material having some degree of elasticity.

The extension body 3233 may extend from one end of the two-stage molded body 3232 without an inclination angle.

The protruding coupler 3234 is bent at an angle of 90° from one side of the extension body 3233 to protrude and extend, and may be combined with the glass fixing part 3260.

The first wing portion 3240 may be inserted into one side of the central coupling portion 3220 and fixedly coupled by a screw to protect the upper portion of the coupling unit 320 .

The second wing portion 3250 is inserted into one side of the central coupling portion 3220 and fixedly coupled by a screw to protect the lower portion of the coupling unit 320 .

The glass fixing body 3263 is bent and extended by 90 ° from the mounting body 3262, and the inside of the end is bent in a 'c' shape so that the glass fixing member 32632 does not escape, so that the separation prevention part ( 32631), and the outer side may be formed bent in a 'b' shape so that it can be fitted into the first wing part 3240 or the second wing part 3250.

Here, the glass fixing member 32632 is made of silicon, and one side is formed in the shape of an octopus foot to maximally prevent the flow of glass by contacting the glass, and the other side is formed in the shape of an arrow to prevent the separation. It may be characterized in that it includes a fixing part (32632-2) inserted into and fixed to the part.

The cover 3270 may be coupled to the central coupling portion 3220 through a coupling member 3271 on the front side and protect the glass fixing portion 3260 and the gap providing portion 3230 .

On the other hand, as an additional embodiment, the coating material 500 applied to protect the surface of the support frame 300 from scratches, shocks, invasions, etc. is disclosed. In particular, the coating material of the present invention has fine grooves in the coating layer to expose the surface of the supporting frame 300, as well as scratches or corrosion on the outer surface. There is a need to maintain a transparent state so that it can be confirmed in real time. .

As a means to meet the above needs, the coating material 500 is a first coating layer 510 in contact with the outer surface of the supporting frame 300, and a second coating provided on the top of the first coating layer 510 A layer 520, a third coating layer 530 provided on the second coating layer 520, and a fourth coating layer 540 provided on the third coating layer 530 may be included.

Each of the first coating layer 510 and the third coating layer 530 includes 100 parts by weight of an acrylic monomer composed of 70 to 99% by weight of butyl acrylate and 1 to 30% by weight of acrylonitrile, 0.1 to 5 parts by weight of a radical initiator, and It may include 0.01 to 20 parts by weight of a crosslinking agent.

Butyl acrylate has a glass transition temperature of less than 0℃ when polymerized with a homopolymer, and acrylonitrile has a glass transition temperature of 80℃ or higher when polymerized with a homopolymer.

When the content of butyl acrylate is less than 70% by weight, the glass transition temperature is increased, resulting in reduced impact resistance and generation of haze. In addition, when the content exceeds 99% by weight, the glass transition temperature is excessively low, resulting in poor wear resistance, which is undesirable.

When the content of acrylonitrile is less than 1% by weight, the glass transition temperature is too low, resulting in a decrease in adhesion durability, and when the content exceeds 30% by weight, there is a problem in that initial adhesive strength decreases, which is not preferable.

A radical initiator is used for polymerization of an acrylic monomer, and commercially available radical initiators may be used. The crosslinking agent is added to crosslink the acrylate-based copolymer obtained by polymerizing butyl acrylate and acrylonitrile, and hexanediol diacrylate, for example, may be used. If the content ratio of the cross-linking agent is less than 0.1 parts by weight, the sheet becomes flexible and cutability decreases, resulting in a decrease in productivity, and if the content ratio exceeds 20 parts by weight, it becomes hard, reducing impact resistance and causing brittleness, which is not preferable. .

Each of the first coating layer 510 and the third coating layer 530 may maintain adhesive strength at a high temperature and simultaneously maintain a transparent state. Of course, the first coating layer 510 and the third coating layer 530 may contain other commercially available additives on the premise that adhesive strength is maintained at a high temperature (about 37° C. or higher) and a transparent state is maintained.

The second coating layer 520 is provided on top of the first coating layer 510 to be described later, and is disposed between the first coating layer 510 and the third coating layer 530, and is indium tin oxide (Indium Tin Oxide). Oxide), which generates heat when DC or AC electricity is applied, and is characterized by being transparent.

The fourth coating layer 540 is provided on top of the second coating layer 520, and a first solution in which 3.84 g of N-isopropyl acrylamide (NIPAM) polymer and 1.25 g of sodium alginate are dissolved per 250 ml of distilled water and A conversion agent mixed with a second solution containing 3% calcium chloride and 0.5% ammonium persulfate in 300 ml of distilled water, 5 to 30 parts by weight of methyltrimethoxysilane, 20 to 75 parts by weight of colloidal alumina, 30 parts by weight of isopropyl alcohol It may contain a protecting agent comprising below parts.

The first solution and the second solution are degassed with nitrogen gas, respectively, and the first solution is dropped into the stirred second solution drop by drop using a syringe. At the same time as the drop is made, fine particles containing calcium alginate as macrocapsules are generated. . The polymerization of the encapsulated NIPAM is completed within 1 to 3 hours, and the obtained fine particles can be washed 3 to 7 times with distilled water.

This converting agent exists in a transparent state below about 37 ° C., and at a state above 37 ° C., the uncrosslinked polymer becomes insoluble in the fine particles and becomes cloudy, so it is converted to an opaque state. When the temperature is lowered to 37° C. or lower again in an insoluble state, the converting agent is converted to a transparent state, and the transparent and opaque state can be reversibly changed.

The protective agent may be ultrasonically dispersed after mixing 5 to 30 parts by weight of methyltrimethoxysilane, 20 to 75 parts by weight of colloidal alumina, and 30 parts by weight or less of isopropyl alcohol by stirring for about 1 hour. It has excellent abrasion resistance, chemical resistance, corrosion resistance, weather resistance, and thermal stability.

In this way, the support frame 300 has an advantage that scratches, corrosion, etc. can be suppressed by being provided with a coating material 500 including a protective agent having excellent wear resistance and corrosion resistance on the outer surface.

In addition, since the coating material 500 is maintained in a transparent state at 37° C. or less, it is possible to check in real time whether scratches or corrosion have occurred on the surface provided with the coating material 500 .

In addition, when electricity is applied to the second coating layer 520, the second coating layer 520 generates heat and transfers heat to the change agent, and when the change agent exceeds 37° C., the fourth coating layer containing the protective agent becomes cloudy and becomes cloudy. (540) becomes opaque. On the other hand, the first transparent adhesive layer (G1), the second coating layer 520, and the third coating layer 530 maintain a transparent state, and the color of the support frame 300, which was in an opaque state, and the fourth coating Since the color of the layer 540 is contrasted, it is possible to easily grasp the location of the groove or the like in the fourth coating layer 540 .

As described above, the third coating layer 530 maintains adhesive strength even at a high temperature exceeding 37 ° C. By newly introducing the 540, maintenance can be easily performed.

Although the preferred embodiments of the present invention have been shown and described above, the present invention is not limited to the specific embodiments described above, and is common in the art to which the present invention pertains without departing from the gist of the present invention claimed in the claims. Of course, various modifications are possible by those with knowledge of, and these modifications should not be individually understood from the technical spirit or prospect of the present invention.
