The present invention relates to a dry curtain wall unit comprising a unit connection part using a silicone sponge or the like inside a curtain wall constructed on an outer wall of a building, thereby forming an inner hermetic layer and a dry curtain wall unit for preventing leakage. It is about.

Generally, the structure of the main body responsible for the load of the building is composed of only the frame of the column and the beam, and supports the vertical load applied to the building and the horizontal load due to the wind. Since the wall is merely a partition for partitioning the space, Quot; curtain wall " or " non-proof partition wall ". Curtain walls are used to block rain and wind from the outside, to block noise and heat, to prevent columns and beams from being exposed to the outside, and to perform important functions for exterior use in modern architecture. Especially, It is often used in skyscraper buildings.

Here, in the construction process of the curtain wall, a method of attaching a certain size outer wall panel (hereinafter referred to as 'curtain wall unit') produced at the factory by lifting it to the outer wall of the building by mechanical means and attaching it to each other. I use it a lot.

That is, according to the dry curtain wall unit 300 of the present invention, by the airtight line generated by the dry curtain wall unit 300, the air pressure of the hollow layer of the dry curtain wall unit 300 and the outside An isostatic space is formed in which the air pressures are equal. (See FIGS. 2 and 6.)

More specifically, the dry curtain wall unit 300 of the present invention includes a pair of vertical members 110 constituting a rectangular frame and a pair of horizontal members 120 orthogonal to the vertical members 110; Vertical gaskets 141 and horizontal gaskets 142 coupled to the vertical member 110 or the horizontal member 120, respectively; And a sealing sponge 150 coupled to a portion where the pair of opposed vertical gaskets 141 and the horizontal gasket 142 cross at right angles.

Therefore, according to the dry curtain wall unit 300 of the present invention configured as described above, it is possible to block the outside air from flowing through the curtain wall unit, to improve the airtight performance of the building.

In addition, by allowing the pressure outside the building (A2 in FIG. 2) to be equally applied to the hollow layer A1 on one side of the curtain wall unit 200, an isostatic space can be formed. (See FIG. 6. )

As such, each of the dry curtain wall units 300 produced and assembled at the factory is combined with each other in a construction site to cover the exterior of a building, and the airtightness must be maintained between the dry curtain wall units 300 connected to each other. .

The sealing sponge 150 serves to maintain airtightness by filling gaps that may exist between the dry curtain wall units 300 when they are connected to each other (see FIG. 5).

At this time, the sealing sponge 150 is made of an injection molding in which silicon (EPDM; ethylene propylene diene monomer, PVC; polyvinyl chloride, TPV; thermoplastic Vulcanizate, etc.) is integrally bonded to the outer circumference of the base plate of steel It is fastened as a screw to the horizontal member 120 through a screw hole 151 formed in.

In addition, the dry curtain wall unit 300 may be further provided with additional sealing means above and below the sealing sponge 150.

Conventionally, when the curtain wall units are assembled together from left to right in a construction site, silicon is applied to the contacted areas for airtightness of the contacted areas, and the applied silicon is dried to have a sealing function.

However, in the present invention, the silicone coating process is omitted, and the sealing sponge 150 is used to fill the gap between the dry curtain wall unit 200 and the dry curtain wall unit 300 to maintain airtightness. This is referred to as a dry curtain wall unit in the present invention.

Here, the main components of the dry curtain wall unit 300 of the present invention will be described in more detail.

In the dry curtain wall unit 300 of the present invention, the vertical member 110 is an aluminum material produced by extrusion, is installed in a direction parallel to the glass panel (130).

In addition, the horizontal member 120 of the present invention is made of an extruded aluminum material, and is installed in a direction orthogonal to the vertical member 110.

In addition, the vertical gasket 141 and the horizontal gasket 142 is a component that is in close contact with one side of the vertical member 110 and the horizontal member 120, respectively, to maintain airtightness.

In addition, the sealing sponge 150 is provided with a through hole 151 on one side, and is fastened with a screw (not shown) to the horizontal member 120, between the dry curtain wall unit 300 is assembled from the side As it is arranged for the airtightness, it is characterized in that the integral plate and the base plate made of steel (steel) and silicon (EPDM, PVC, TPV).

Here, the outer shape of the sealing sponge 150 is shown in FIG.

Referring to FIG. 6, the principle in which an equal pressure space is formed between a rain screen Rs and an outer wall system S forming an airtight line will be described.

As shown, a rain screen (Rs) is provided in the front of the outer wall system (S) is provided with an opening (H) in the center, the outer wall system (S) to maintain a completely airtight state Accordingly, the air pressure at the rear of the outer wall system S is different from the pressure of the air Ai at the front of the outer wall system S, but the pressure of the air Ai at the front of the outer wall system S is It is formed equal to the pressure of the air Ao in front of the rain screen Rs, so that an isostatic space is formed between the rain screen Rs and the outer wall system S. Is formed.

Here, the opening (H) provided in the rain screen (Rs) is a through-hole in the dry curtain wall unit 300 of the present invention, penetrates to one side of the horizontal member 120 to allow rain water, etc. to pass through. (Not shown).

Therefore, according to the dry curtain wall unit 300 of the present invention, by making the internal and external pressure of the outer wall equal, it is possible to prevent leakage due to gravity, kinetic energy, surface tension and capillary phenomenon.

Referring to Figures 7 to 9, looks at the coupling position, the appearance and the effect of the isostatic member 160.

7 is a perspective view illustrating a state in which an isostatic compartment member is coupled to a central portion of an upper portion of the horizontal member, FIG. 8 is a cross-sectional view illustrating an isostatic compartment member coupled to an upper portion of the horizontal member, and FIG. Perspective view.

7 to 9, an equal pressure partition member 160 is coupled to a central portion of an upper surface of the horizontal member 120 positioned at the top of each curtain wall unit 200. (See FIGS. 7 and 8).

Here, the horizontal member 120 is connected to be arranged along the outer wall of the building based on the state, the series of horizontal members 120 and the horizontal member 120 is disposed on the upper side of the building along the outer wall circumference Hollow layers are formed between another series of horizontal members 120 which are connected and arranged, and these hollow layers pass through the interior as one body in a shape of a taste (ㅁ) along the circumference of the building.

Therefore, when water leakage occurs in the curtain wall unit 200 arranged along the circumference of the building in a state where the separate isostatic compartment member 160 is not coupled, it is determined which curtain wall unit 200 has leaked. It can't be pinpointed, so accurate maintenance is not possible.

However, as shown in FIG. 7 and FIG. 8, when the equal pressure partition member 160 is coupled to the upper surface of the uppermost horizontal member 120 of each curtain wall unit 200, the sound is reduced along the circumference of the building. Hollow layers formed of a ruler are distinguished from each other as a constant unit independent space as the intermediate intermediate is broken by the equal pressure partition members 160 coupled to one side of each curtain wall unit 200.

That is, in the state where another horizontal member 120 of another curtain wall unit 200 neighboring up and down is coupled, the inner space formed by the pair of horizontal members 120 facing in the vertical direction is the equal pressure compartment. The member 160 is divided into two parts in the longitudinal direction.

Therefore, when a leak occurs in the dry curtain wall unit 300, it is possible to determine exactly how many leaks occurred in the dry curtain wall unit 300, the minimum range around the dry curtain wall unit 300 By re-installing or repairing the construction, the problem can be solved and maintenance becomes easy.
