Description
- The present invention relates to a door or window system having earthquake-resistant performance.
- A door or window system includes a variety of windows or doors installed to an opening, such as a window frame or doorway, to shut an inner space of a building from the outside. Such doors or windows are essential in lighting or ventilating the room in the building and are installed into a quadrangular space, which is provided at a predetermined position of a wall body when the building is constructed.
- The kind, size, installation position, number, and the like of the door or window are appropriately designed in consideration of loads applied to the building as well as air-conditioning, keeping warmth, lighting in the room, and the like. Since the door or window is generally installed to a wall body between columns, a vertical load, which the door or window cannot bear, is not applied to the door or window itself. Columns, bearing walls and the like serve to mainly support the vertical load of the building, and the door or window serves to connect the interior and the exterior.
- In the meantime, when a strong wind strikes a building or an earthquake occurs, a horizontal load is applied to the building. The horizontal load, which shakes the building side to side, makes the building easily destroyed. Destruction of a building, bridge or the like when an earthquake occurs is mostly caused by the horizontal load.
- Also, the aforementioned horizontal load is concentrated on a portion of the door or window of the building, so that the door or window is very easily destroyed. Thus, if the building is destroyed due to the earthquake, the wall body at which the door or window is positioned first collapses, and thus, people trapped in the interior cannot escape.
- The present invention is conceived to solve the aforementioned problems. An object of the present invention is to provide a door or window system having earthquake-resistant performance, which is plastically deformed by a horizontal load and has stable hysteretic characteristics while a yield strength is continuously increased particularly during the plastic deformation, thereby being capable of maintaining the door or window system to be stable just before fracture; has a damper to absorb earthquake energy, thereby performing functions of preventing a building structure from being damaged and improving earthquake-resistant performance; and also, can be installed newly when the building is constructed or installed at a place where an existing door or window is removed because of having the same constructability as a general door or window system.

-
FIG. 1 is a view illustrating a door orwindow system 13 having earthquake-resistant performance according to one embodiment of the present invention, andFIG. 2 is a front view of the door or window system shown inFIG. 1 . - As shown in the figures, the door or
window system 13 according to this embodiment comprises amain frame 15 mounted to an inner area of a quadrangular hole, which is formed in aframework 11 when a building is constructed, threepillar members 23 provided inside of themain frame 15, asupport beam 19 horizontally fixed to an upper end of thepillar members 23, and a plurality ofdampers 17 positioned on top of thesupport beam 19. - The
main frame 15 takes the form of a quadrangular frame consisting of twovertical frame members 15 a arranged to be spaced apart from and parallel to each other, anupper frame member 15 b integrally formed at upper ends of thevertical frame members 15 a and horizontally extending, and alower frame member 15 c integrally connected to lower ends of thevertical frame members 15 a and parallel to theupper frame member 15 b. Thevertical frame members 15 a may function as columns, and theupper frame member 15 b may function as a beam. - The
pillar members 23, which are made to stand vertically with their lower ends fixed to thelower frame member 15 c, are spaced apart from each other at regular intervals, so that door orwindow installation spaces 27 are provided between thepillar members 23. The door orwindow installation spaces 27 are mounted withgeneral windows 29, respectively. - In particular, the
pillar members 23 at the left and right sides among the threepillar members 23 are respectively spaced apart from thevertical frame members 15 a, so thatspace portions 25 are defined between thepillar members 23 and thevertical frame members 15 a, respectively. Each of thespace portions 25 may has a width of about 40 mm to 50 mm although it may vary according to circumstance. - The
space portions 25 are buffer regions provided so that thevertical frame members 15 a do not collide with thesupport beam 19 or thepillar members 23 when a horizontal load is applied to theupper frame member 15 b in an arrow direction F. If there is not thespace portions 25, the horizontal load is exerted directly on thepillar members 23, thereby making thepillar members 23 yield and be plastically deformed. - The
window 29 mounted to the door orwindow installation space 27 is a general window, for example, including a fixed sash type or an openable type. When thewindow 29 is a fixed sash type, thewindow 29 consists of aquadrangular window frame 29 a fixed to thepillar members 23, thelower frame member 15 c and thesupport beam 19 and aglass panel 29 b fitted into thewindow frame 29 a. Also, thewindow 29 of an openable type consists of thequadrangular window frame 29 a and a window sash 29 c openably and closably installed into thewindow frame 29 a. Theglass panel 29 b may be naturally fitted into thewindow sash 29 c. - Also, although in this embodiment, the
pillar member 23 takes the form of a plate having a predetermined width and thickness, the shape of thepillar member 23 may be modified in any degree according to circumstance. - The
support beam 19 fixed to the upper ends of thepillar members 23 horizontally extends, and both ends of thesupport beam 19 are respectively spaced apart from thevertical frame members 15 a. Spaces between both the ends of thesupport beam 19 and thevertical frame members 15 a are also respectively included in thespace portions 25. Thesupport beam 19 is spaced apart from theupper frame member 15 b in parallel, and the plurality ofdampers 17 are maintained between thesupport beam 19 and theupper frame member 15 b. - Each of the
dampers 17 is a plate-shaped member, which has a predetermined width and thickness and extends in a longitudinal direction of thesupport beam 19. Thedampers 17 are made to vertically stand between thesupport beam 19 and theupper frame member 15 b, and both widthwise ends of eachdamper 17 are respectively coupled to a bottom side of theupper frame member 15 b and a top side of thesupport beam 19. In particular, thedamper 17 is formed with a plurality ofholes 17 a. The plurality ofdampers 17 are serially arranged along the longitudinal direction of thesupport beam 19. Thedampers 17 may be formed of the same material, preferably steel, as themain frame 15. - The
hole 17 a is a slot-shaped hole, which vertically extends to be elongated, and improves a plastic deformability of thedampers 17. That is, when the horizontal load is applied to theupper frame member 15 b in the arrow direction F and then a shear force is exerted on thedampers 17, thedampers 17 are plastically deformed due to the shear force. If there is not theholes 17 a, thedampers 17 are not plastically deformed, but for example, welded portions of upper and lower ends of thedampers 17 or other portions thereof will be fractured. As described above, thedampers 17 are installed and applied so that thedampers 17 are plastically deformed by the horizontal load, whereby for example even when an earthquake occurs, energy of the earthquake will be absorbed due to the plastic deformation of the dampers. A width w of thehole 17 a may vary according to circumstance. - Also, a plurality of
escape prevention members 21 are positioned between thesupport beam 19 and theupper frame member 15 b. Theescape prevention members 21, each of which is a plate having a predetermined thickness, are fixed in a direction perpendicular to thedampers 17. Upper and lower ends of theescape prevention members 21 are welded and coupled to theupper frame member 15 b and thesupport beam 19, respectively, thereby preventing thesupport beam 19 from moving in its widthwise direction with respect to theupper frame member 15 b. That is, theescape prevention members 21 prevent thesupport beam 19 from moving in the widthwise direction of thesupport beam 19 and then tumbling to the outside of themain frame 15. - The installation number or installation positions of the
escape prevention members 21 may also vary according to circumstance, and as shown inFIG. 1 , theescape prevention members 21 may be positioned between therespective dampers 17 and at both the ends of thesupport beam 19. -
Reference numeral 31 inFIG. 2 designates an epoxy layer. Theepoxy layer 31 bonds themain frame 15 to inner sides of theframework 11 and at the same time functions as a buffer for blocking the propagation of vibration. -
FIG. 3 is a graph showing an analysis of an internal stress distribution in the door orwindow system 13 having earthquake-resistant performance shown inFIG. 1 using FEM (Finite Element Method), which is one of numerical analyses, when the horizontal load is applied to the door or window system in the arrow direction F shown inFIG. 2 . - Referring to
FIG. 3 , it can be seen that stress is concentrated on thedampers 17 and stress in an elastic range exists in the other portions of the door or window system. The stress in an elastic range is a load to restore an object to its original state when the load is removed from the object. - Since the stress is concentrated on the
dampers 17 as described above, if a strong horizontal load caused by an earthquake is transmitted to the door orwindow system 13, thedampers 17 are first plastically deformed and absorb energy of the earthquake, thereby being capable of serving to prevent damage of the building structure as well as the door orwindow system 13. -
FIG. 4 is a view showing another example of the door orwindow system 13 having earthquake-resistant performance according to one embodiment of the present invention. - Hereinafter, the same reference numerals as the aforementioned ones are used to designate the same members having the same function.
- In the door or
window system 13 shown inFIG. 4 , thedampers 17 are serially arranged in pairs. The configuration and function of thedamper 17 itself is the same as the one shown inFIG. 1 . Since thedampers 17 are fixed in pairs side by side as described above, they can strongly bear the horizontal load applied from the outside. According to circumstance, thedampers 17 may be arranged in sets of three or more side by side. -
FIG. 5 is a view showing a further example of the door or window system having earthquake-resistant performance according to one embodiment of the present invention. - Referring to
FIG. 5 , it can be seen that thedampers 17 are fixed to a top side of thelower frame member 15 c. To this end, the upper ends of thepillar members 23 are fixed to theupper frame member 15 b and extend downward, and thesupport beam 19 is fixed to the lower ends of thepillar members 23. - The
support beam 19 is arranged above thelower frame member 15 c in a parallel spaced relation, and thedampers 17 are positioned between thesupport beam 19 and thelower frame member 15 c. Thedampers 17 have the same functions as those shown inFIG. 1 . -
FIG. 6 is a view showing a still further example of the door or window system having earthquake-resistant performance according to one embodiment of the present invention. - As shown in the figure, in the door or
window system 13 according to the still further example, themain frame 15 further includes anintermediate frame member 33 between theupper frame member 15 b and thelower frame member 15 c. Theintermediate frame member 33 has both ends fixed to thevertical frame members 15 a and is maintained in a horizontal state. - Also, the plurality of
dampers 17 andescape prevention members 21 are fixed to top and bottom sides of theintermediate frame member 33. Thedampers 17 and theescape prevention members 21 have the same functions as those described above. - The
support beam 19 is positioned on top of thedampers 17 andescape prevention members 21 arranged on top of theintermediate frame member 33, and a plurality ofupper pillar members 23 a are positioned on top of thesupport beam 19. - The
upper pillar members 23 a connect theupper frame member 15 b and thesupport beam 19 to each other, and door orwindow installation spaces 27 are provided therebetween. Thewindows 29 are naturally installed to the door orwindow installation spaces 27. - In addition,
lower pillar members 23 b are fixed to an upper portion of thelower frame member 15 c. Thelower pillar members 23 b are spaced apart from each other to provide door orwindow installation spaces 27 therebetween, and thesupport beam 19, which is further provided in addition to theaforementioned support beam 19, is supported at upper ends of thelower pillar members 23 b. Thesupport beam 19 is maintained in a horizontal state while being supported by thelower pillar members 23 b, and thedampers 17 and theescape prevention members 21 are held between thesupport beam 19 and theintermediate frame member 33. - The
dampers 17 fixed to the top and bottom sides of theintermediate frame member 33 are plastically deformed by the horizontal load applied to the door orwindow system 13, particularly theintermediate frame member 33, to protect the door or window system. - Meanwhile, although the plate-shaped
dampers 17 made of steel are employed in this embodiment, the shape or kind of the dampers may be modified in any degree as long as the dampers perform their aforementioned functions. For example, an elastic damper, a viscoelastic damper, a steel damper, an oil damper, a viscous damper, or the like may be applied. - Although the present invention has been described in detail through the specific embodiments, the present invention is not limited to the embodiments. It will be apparent that those skilled in the art can make various modifications and changes thereto within the scope of the technical spirit of the present invention.
