Description

Curtain wall structure of glass windows

The present invention relates to a curtain wall structure of a glass window for finishing an outer wall by finishing with glass, and more particularly, to a curtain wall structure of a glass window to improve structural rigidity and to have excellent thermal insulation performance.

In general, the curtain wall structure of the glass window is different depending on the opening of the glass window installed in the building.

As shown in FIG. 1, the curtain wall structure 10 of the conventional fixed glass window has an aluminum frame 11 fixed to an outer wall of the building and an aluminum window extending toward the outside from the center of the outer surface of the aluminum frame 11. A connecting piece 12, a glass window 13 positioned at both sides of the aluminum window connecting piece 12, a glass fixing tape 14 attached to an outer surface of the aluminum frame 11, and the glass fixing tape ( 14, a backing material 16 inserted between the aluminum window connecting piece 12 and the glass window 13, and an external waterproof silicon 17 filled in the backing material 16. do.

And, Figure 2 is a cross-sectional view showing the curtain wall structure 20 of the open glass window, as shown, the aluminum frame 21 is fixed to the outer wall of the building, and the outdoor from the center of the outer surface of the aluminum frame 21 An aluminum window connecting piece 22 extending toward the center, a window frame 23 fixed to both sides of the aluminum frame 22, a window frame 24 provided to be open to the window frame 23, and the window frame 24. ) Is fitted along the side of the window frame 24 and the window frame 24 to be in close contact with the aluminum window connecting piece 22 so that outside air and rainwater do not flow between the aluminum window connecting piece 22 and the window frame 24. The first strip member 26 is blocked so as to be fitted along the inner surface of the window frame 24 to be in close contact with the window frame 23 so that outside air and rainwater do not flow between the window frame 24 and the window frame 23. The second strip member 27 to block It is.

Unexplained reference numeral 28a is a glass fixing tape, 28b is an internal structural silicone filled in the glass fixing tape, 28c is a backup material inserted between the window frame and the glass window, 28d is an external waterproof silicone filled in the backup material.

The curtain wall structure 10 and 20 of the conventional glass window having such a structure has the following problems.

First, the length of the aluminum frames 11 and 21 is unavoidable in view of the trend of increasing the height between floors of the curtain wall structures 10 and 20 of the conventional glass doors. Therefore, it is expected that the structural rigidity will be weak and the economic efficiency will be greatly reduced.

Therefore, a method of applying the frame with steel having excellent rigidity instead of the aluminum frames 11 and 21 is considered, but since steel is relatively inferior in workability, it is difficult to manufacture a steel frame having a complicated shape in which window connecting pieces are formed. Very difficult situation.

Second, the curtain wall structure (10, 20) of the conventional windows and glass is an aluminum frame through the aluminum window connecting piece (12, 22) as the cold window is continuously contacted with the outside air aluminum connecting piece (12, 22) exposed to the outside There is a problem that the conduction along (11, 21) is greatly reduced thermal insulation performance.

Third, the curtain wall structure 10 of the conventional fixed glass window is because the insertion depth of the backing material 16 is fluid, so the insertion depth of the backing material 16 is too shallow, as shown in the right backing material 16 of FIG. If the charge of the silicon 17 is not sufficiently made, a problem that the heat insulation and rainwater flows through this portion is greatly reduced the heat insulation and waterproof performance.

Fourth, since the aluminum wall 21 and the window frame 23 are in contact with each other because the curtain wall structure 20 of the conventional open glass window is cold air is conducted to the aluminum frame 21 through the aluminum window connecting piece 22. The window frame 23 also has a problem in that the cold air is conducted to significantly reduce the thermal insulation performance.

The present invention has been made to solve the above problems of the prior art, and an object of the present invention is to provide a curtain wall structure of glass doors that have improved structural rigidity and economic efficiency, and improved weak insulation and waterproof performance.

Curtain wall structure of the glass window to achieve the object of the present invention as described above is a cover plate made of a steel frame fixed to the structural part of the building, a synthetic resin material fixed to the outer surface of the steel frame, and the outside of the cover plate A connection bracket fixed to the side and having a window connecting piece extending toward the outside, an insulating cap made of a synthetic resin material removably covered by the window connecting piece of the connecting bracket, and spaced apart from both sides of the window connecting piece of the connecting bracket. It comprises a glass window, a position fixing means for applying a fixing force to the glass window, and a sealing means for preventing the inflow of outside air and rainwater flowing between the insulating cap and the glass window and between the connection bracket and the glass window. .

According to the curtain wall structure for the glass window of the present invention configured as described above has the following effects.

First, since the present invention uses a steel frame having a simple structure, the structural rigidity is greatly improved and economical efficiency is superior to that of the conventional aluminum frame.

Second, the present invention is a cover plate made of a synthetic resin material is tightly fixed so that the steel frame is not exposed to the outside air, the window connecting piece of the connection bracket fixed to the cover plate is covered with an insulating cap made of synthetic resin material, so cold air from the outside Minimizing the conduction to the frame has the effect of greatly improving the thermal insulation performance.

Third, the present invention is the interference portion is formed on the window connecting piece of the connection bracket is always inserted into the gap between the insulating cap and the glass window with a constant depth, so that the external waterproof silicone is always filled to a certain thickness to improve the waterproof and insulation performance is greatly improved. have.

Fourth, the present invention is the first strip member is fitted along the side of the window frame in close contact with the insulating cap in the case of the open window, the second strip member is fitted along the inner surface of the window frame in close contact with the connecting bracket Therefore, even if the sealing force of the first strip member is lowered so that outside air or rainwater flows in, there is an effect that the inflow of outside air or rainwater to the window frame is reliably blocked by the second strip member.

The features and advantages of the present invention will become more apparent from the following detailed description of preferred embodiments with reference to the accompanying drawings. Prior to this, the terms or words used in the present specification and claims are defined in the technical spirit of the present invention on the basis of the principle that the inventor can appropriately define the concept of the term in order to explain his invention in the best way. It must be interpreted to mean meanings and concepts.

DETAILED DESCRIPTION Hereinafter, one embodiment of the present invention will be described in detail with reference to the drawings. Like reference numerals refer to like elements, and only different parts will be mainly described so as not to overlap for clarity.

As shown in Figures 3 to 5, the curtain wall structure 100 of the glass window is a steel plate 110, a cover plate 120 made of a synthetic resin material tightly fixed to the outer surface of the steel frame 110, The window bracket connecting piece 131 extending toward the outside and fixed to the outer surface of the cover plate 120 and the cover bracket 130, which is detachably covered with the window connecting piece 131 of the connecting bracket 130 Insulating cap 140 made of a synthetic resin material, glass doors 150 respectively located on both sides of the window connecting piece 131 of the connecting bracket 130, and position fixing means for applying a fixing force to the glass window 150 and It is composed of a sealing means that prevents the inflow of outside air and rainwater flowing between the heat insulating cap 140 and the glass window 150 and between the connection bracket 130 and the glass window 150.

The steel frame 110 is a beam-shaped member that is fixed to the structural portion of the building, it is usually fixed to the outside of the structural portion (not shown) of the building by bolting or welding. The steel frame 110 has a relatively simple cross-section that can be easily manufactured by using a steel steel sheet in consideration of the structural strength and low cost but relatively weak formability compared to the conventional aluminum frame. desirable. In this embodiment, the steel frame 110 has a rectangular cross section, for example shown and described.

The cover plate 120 is tightly coupled to the outer surface of the steel frame 110 in a state that covers the entire outer surface of the steel frame 110 so that the steel frame 110 is not exposed to the outside air. Since the cover plate 120 is made of a synthetic resin having a very low conductivity, it is possible to minimize the conduction of cold air toward the steel frame 110 due to contact with the outside air.

The connection bracket 130 fixed to the outer surface of the cover plate 120 is tightly fixed to the steel frame 110 together with the cover plate 120 through the fastening bolt (B). The connecting bracket 130 has a window connecting piece 131 extending toward the outside. Therefore, the cover plate 120 has an overall "T" shape. The glass window 150 is positioned to be spaced apart at a predetermined distance from both sides of the window connecting piece 131.

On the other hand, the outer surface of the steel frame 110, the insertion groove 111 is formed, the inner surface of the cover plate 120 so that the fitting protrusion 122 is fitted in close contact between the insertion groove 111 is formed. It is desirable to. In this case, since the cover plate 120 may be temporarily fixed while being preassembled to the steel frame 110, it is very easy to fix the connecting bracket 130 to the steel frame 110.

In addition, it is preferable that the stepped portion 121 protrudes toward the outside along both side ends of the cover plate 120. In this case, the stepped part 121 guides the connecting bracket 130 to be positioned at the correct position on the outer surface of the cover plate 120 and at the same time the connecting bracket 130 is attached to the outer surface of the cover plate 120. Restricts flow from both sides when locked.

In addition, the cover plate 120 and the connection bracket 130 is preferably to be coupled through the groove 123 and the protrusion 132. This allows the connecting bracket 130 to be placed in the correct position on the outer surface of the cover plate 120 while being separated from the cover plate 120 when the connecting bracket 130 is fixed to the outer surface of the cover plate 120. This is to ensure that the fixing operation of the connection bracket 130 can be made easily. In the present embodiment, for example, the groove 123 is formed on the outer surface of the cover plate 120 and the protrusion 132 is formed on the inner surface of the connecting bracket 130, but the outer surface of the cover plate 120 is shown. A protrusion may be formed and a groove may be formed on the inner surface of the connection bracket 130.

The cover plate 120 and the connection bracket 130 are simultaneously fastened to the steel frame 110 through a fastening bolt B fastened from the outside of the connection bracket 130.

The insulating cap 140 which is covered at the end of the window connecting piece 131 of the connection bracket 130 is made of synthetic resin to block the end of the window connecting piece 131 from contacting the outside air, as well as the window connecting piece 131. Minimizes conduction.

On the other hand, the insulation cap 140 is caught on the one side of the window connecting piece 131 so as not to be separated from the window connecting piece 131 by an external force acting on the outside in the state covered with the end of the window connecting piece 131. 133 is formed and a locking groove 141 that is fitted to the locking step 133 may be formed at the inner end of the insulating cap 140.

Glass windows 150 are positioned on both sides of the window connecting piece 131 of the connecting bracket 130. The glass window 150 is fixed through a separate position fixing means in a state spaced apart from the window connecting piece 131 by a predetermined distance, between the insulating cap 140 and the glass window 150 and the connection bracket 130 and the glass window Outside air and rainwater flowing between the arc 150 is blocked through a separate sealing means.

The glass window 150 has different position fixing means and sealing means depending on whether or not open.

As shown in FIG. 3, in the case of the fixed glass window 150 which cannot be opened, the position fixing means is attached to the outer surface of the cover plate 120 to fix the glass window 150 to the cover plate 120. It becomes the glass fixing tape 161.

The sealing means includes a backing material 172 inserted between the internal structural silicon 171 filled in the glass fixing tape 161, the insulating cap 140 and the glass window 150, and the backup. It is composed of an external waterproof silicone 173 filled in the ash 172.

In this case, the interference part interferes with the backup material 172 on the side of the thermal insulation cap 140 so that the backup material 172 can be inserted between the thermal insulation cap 140 and the glass window 150 at a constant depth. 142 is preferably formed. As such, when the backup material 172 is always inserted between the heat insulating cap 140 and the glass door 150 at a constant depth, it is possible to fill the external waterproof silicone 173 with a constant thickness at all times, thereby significantly improving the sealing reliability. Can be.

And, the heat insulating cap 140 is preferably formed to be located on the inner side than the outer surface of the glass window (150). This is to prevent the end of the insulating cap 140 to be exposed to the outside of the external waterproof silicone 173 so that the appearance of the building is greatly improved.

As shown in Figure 4, in the case of an open glass door 150, the glass door 150 is installed to be open to the window frame 151 and the window frame 151 fixed to the side of the steel frame 110. It consists of a window frame 152 and a glass window 153 fitted to the window frame 152. Then, the position fixing means is a fastening bolt 162 for fixing the side of the window frame 151 and the steel frame 110 of the glass window 150. In addition, the sealing means may include a first strip member 174 fitted along the side of the window frame 152 to be in close contact with the insulating cap 140, and the window frame 152 to be in close contact with the connection bracket 130. It consists of a second strip member 175 fitted along the side.

Since the second strip member 175 is located in front of the window frame 151, even if the sealing force of the first strip member 174 is reduced, it is possible to reliably block the inflow of outside air or rainwater to the window frame 151. .

In addition, when the window frame 151 has the stepped portion 121 formed on the cover plate 120, the window frame 151 is in contact with the stepped portion 121, so that the window frame 151 is connected to the connection bracket 130. Contact is blocked at the source. Therefore, even if the sealing force of the first strip member 174 is lowered and the connection bracket 130 is exposed to the outside air or rain, cold air cannot be conducted to the window frame 151 through the connection bracket 130.

Meanwhile, the first and second strip members 174 and 175 may be made of a soft synthetic resin material having excellent elasticity to maximize sealing force.

In addition, as shown in Figure 5, the open glass door 150 and the non-openable fixed glass window 150 may be installed together, which also need to be included in the rights of the invention.
