Description

Slim Curtain Wall System

The present invention relates to a slim curtain wall system, and more specifically, the slim design of the frame can improve visibility and minimize thermal bridge phenomena due to heat conduction, convection, and radiation between glass walls, compared to existing curtain walls. The slim design with the minimum composition minimizes the visual interference of the building and ensures a sense of openness, allows structural reinforcement design to ensure stability, improves architectural finishing and watertightness, and is easy to attach and detach on site, making installation work easier. It is about a slim curtain wall system that can reduce costs and labor costs.

In general, a curtain wall refers to a non-load bearing wall of a building that functions to protect residents from the external environment without supporting the load of the building. In construction, it simply acts as a partition and supports the load. This refers to a non-load-bearing partition or barrier that forms the outer wall. The curtain wall supports the load only with the framework of columns and beams, which are the main structure of the building, and the wall is freed from the load-bearing function of the masonry structure and simply functions as a partition or curtain to divide the space, so it can cause rain, wind, and noise. It is a wall with a large function as an exterior wall that blocks heat, etc., and is mainly installed in high-rise or ultra-high-rise buildings. Materials include metal plates, glass, blocks, plastics, and precast concrete. Considering temperature changes and building vibrations, high-rise buildings use lightweight materials to reduce the building's own weight.

Therefore, in recent years, as architectural structures have become higher-rise, curtain walls have been widely used to construct the exterior walls of buildings, and the demand for slim-designed curtain walls is increasing to improve the sense of openness.

Since most curtain walls are manufactured in factories, mass production is possible, and the panels forming the curtain walls can be standardized and unified. In addition, because curtain walls are light, they can reduce the building's own weight and have the advantage of reducing the thickness of columns or beams. Light materials are used in curtain walls to reduce weight.

However, since most curtain walls cover almost the entire exterior wall with a glass finish for an attractive appearance, they also have disadvantages such as reduced insulation and airtightness, increased heating and cooling costs, and condensation.

Meanwhile, plastics (synthetic resins) such as PVC or non-ferrous metals with a low specific gravity such as aluminum are used as materials for the curtain wall frame.

These days, plastic is being widely used as interior and exterior materials for buildings. Although it has the advantage of excellent insulation performance, it has the disadvantage that the material itself is highly elastic and weak in strength. In particular, its use is limited because it has disadvantages such as low ignition temperature and emission of toxic gases in case of fire.

Polyamide plastic is a type of high-performance resin (engineering plastic) in which the shortcomings of these plastics are complemented and improved. It is a synthetic polymer material with amide bonds in the molecule. Nylon is a representative polyamide resin and is rich in self-lubricating properties, has a low coefficient of friction, and is excellent in wear resistance. In addition, nylon has good impact resistance, heat resistance, a wide range of uses, excellent chemical resistance, low hygroscopicity, and high tensile strength, and its use is increasing, especially in automobiles, and is used in door handles, switch parts, gears, tanks, and buildings. It is currently being actively used in interior materials and heat exchange blocking members that block thermal bridge phenomenon.

Therefore, in recent times, in situations where the size of windows in high-rise buildings has to be increased, metal frames such as aluminum, which have high strength, little expansion and contraction, are excellent in durability, and have a low weight load, are being widely used.

However, metal frames such as aluminum frames have the disadvantage of having high thermal conductivity and large heat loss due to convection, so the factor that reduces the insulation performance in most curtain walls is heat loss from the metal frame.

The performance of windows is evaluated by the area-weighted average of the glass wall and curtain wall frame. In the case of glass walls, the insulation performance is improving with the development of low-emissivity (Low-E) glass, etc., and the insulation performance is improved through methods such as attaching an insulation film made of special materials to the surface. Complementation is possible.

On the other hand, it is not easy to solve the problem of thermal bridge phenomenon in metal frames. In addition, there is a problem in that the thermal bridge phenomenon cannot be blocked because the distance of the insulation space between the metal frame and the glass wall is not sufficiently secured.

In order to solve this problem, Patent Document 1 includes a frame 200 installed on the indoor side between a pair of glass walls 100, as shown in FIG. 1; A thermal bridge blocking material (600) installed between a pair of glass walls (100) to block thermal bridge phenomenon; an airtight member 300 provided between the thermal insulation material 600 and the frame 200 to prevent outdoor air from being conducted into the room; A support member 700 is provided on the outdoor side of the airtight member 300 by fastening hardware 30, and the frame 200 includes a fixed frame 210 fixed on the indoor side; A pair of coupling frames 220 each extending from both front sides of the fixed frame 210 to the outdoor side and to which the airtight member 300 is coupled; A fixing plate 230 formed on one side of the coupling frame 220 and extending from both ends of the fixing frame 210 to secure the airtight member 300; Between the pair of coupling frames 220, there is a seating hole 240 that is bent inside the fixed frame 210 and the center of the airtight member 300 is seated, and the airtight member 300 is connected to the fixed frame 210 and An insulating bracket 400 that is in contact with and blocks the thermal bridge phenomenon transmitted through the glass wall 100; A coupling bracket (500) inserted inside the insulation bracket (400) and coupled with a thermal insulation material (600) at the center; A configuration is proposed that includes fixing hardware 20 that penetrates the insulating bracket 400 and the coupling bracket 500 and is spirally coupled to the coupling frame 220.

However, for the installation of a curtain wall, a frame (200), a thermal insulation material (600), an airtight member (300), a joining hardware (30), a support member (700), a fixed frame (210), an airtight member (300), and a combined frame are required. (220), fixing plate (230), glass wall (100), thermal insulation material (600), coupling bracket (500), insulation bracket (400), and fixing hardware (20), etc. must be organically combined, so each There is a problem in that the cost of manufacturing the parts and the cost of installing them all increase, resulting in an increase in labor costs.

And, the spaced frames 20 can be connected to each other in a grid shape by fastening them to the fasteners 71 and arranged on the outside of the building frame.

And the first thermal break bracket 30 is provided to protrude from the spacing frame 20 toward the glass wall 10, and is fixed to the glass wall 10 by sealing the seal member 40 to connect the glass wall 10 to the glass wall 10.

Here, heat bridge refers to a phenomenon in which a lot of heat enters or leaves an area with low thermal resistance due to a thin structure or missing insulation. The thermal bridge area causes the wall surface to fall below the dew point temperature due to reduced insulation, causing condensation. This can be.

Therefore, the slim curtain wall system of the present invention is designed to prevent thermal bridge phenomenon in the glass wall 10 installed as the outer wall of a high-rise building.

And the first thermal bridge blocking bracket 30 includes a protrusion 31 that extends to a length corresponding to the length of the spacing frame 20 and protrudes to the outside of the glass wall 10; Hook-shaped holding portions 32 that protrude from both sides of the protruding portion 31 at odd intervals along the protruding direction; A coupling portion 33 that is coupled in a sliding manner corresponding to a coupling groove 21 formed in a recess on one side of the spacing frame 20 corresponding to the glass wall 10 is formed integrally, simplifying the overall installation and coupling structure. It can be configured.

The configuration and installation structure of the present invention having the above-described configuration will be described based on each embodiment.
