TECHNICAL FIELD OF THE INVENTION
The present invention relates to a sash.
[0002]
[Prior art]
A configuration is known in which the surface glass is fixed to a rib glass (rib panel) provided on the indoor side, and the surface glass is supported against a positive pressure or a negative pressure applied to the indoor outdoor (Japanese Utility Model Laid-Open No. 63-76119). .
[0003]
[Problems to be solved by the invention]
However, if the surface glass is supported only by the rib glass, sufficient strength cannot be obtained for the rib glass, and therefore there is a need to increase the strength of the rib glass.
[0004]
Therefore, an object of the present invention is to provide a sash capable of increasing the strength of a rib panel.
[0005]
[Means for Solving the Problems]
The invention according to claim 1 includes a front panel, an upper frame and a lower frame holding the front panel, a rib panel supporting the front panel, and a reinforcing member provided in a longitudinal direction along the rib panel, and the upper frame includes: The lower frame is connected to the frame, the lower panel is connected to the frame, and the rib panel is held by the upper and lower frames that hold the front panel. The indoor side portion is connected to the reinforcing member , and the reinforcing member has an upper end fixed to the upper frame and a lower end supported by the frame .
[0006]
According to the first aspect of the present invention, when a negative pressure or a positive pressure is applied to the indoor side of the surface panel due to a pressure difference between the room and the outside or an external wind pressure, the rib panel supports the surface panel against the force applied. I do. The strength of the rib panel is enhanced by the reinforcement member supporting the indoor side portion of the rib panel. Also, precursor is displaced by an earthquake or wind or the like, when the upper frame is moved in the chamber the direction or the outdoor direction, the reinforcing member, since the move to follow the upper frame is connected to the upper frame and the reinforcing member An excessive force is prevented from acting on the rib panel, and the rib panel is prevented from being damaged.
[0007]
[0008]
Further, in the case where there arises the relative horizontal displacement swaying skeleton building by earthquake or wind, because the upper frame and the frame is slidable in the longitudinal direction of the upper frame, precursor to the upper frame of the sash surface Move left and right of panel. In this case, since the reinforcing member is fixed to the upper frame, the reinforcing member follows the upper frame, only the building frame is moved against the reinforcing member. Therefore, since the upper frame and the reinforcing member are located at the same position with respect to the relative horizontal displacement, the rib panel is unlikely to generate a force due to a displacement between the outdoor side and the indoor side, so that the rib panel is prevented from being damaged by the applied force. I do.
[0009]
According to a second aspect of the present invention, in the first aspect, the reinforcing member is a steel material.
[0010]
According to the second aspect of the present invention, the rib panel can be supported with high strength.
[0011]
BEST MODE FOR CARRYING OUT THE INVENTION
Hereinafter, embodiments of the present invention will be described in detail with reference to FIGS. 1 to 8 of the accompanying drawings. As shown in the overall appearance in FIG. 8, the sash 3 holds each surface glass (surface panel) 5 with an upper frame 7 and a lower frame 9, respectively. The sealant (elastic member) 11 is interposed and fixed. The surface glass 5 is supported by a rib glass (rib panel) 13 vertically arranged on the indoor side, and receives the pressure difference between the room and the outside or the wind to move the surface glass 5 to the inside or the outside of the room. , So as not to fall out.
[0012]
As shown in FIGS. 1 and 2, the rib glass 13 is provided with the same plate-shaped glass as the surface glass 5 in the vertical direction, and is arranged so as to form a substantially T-shape with the surface glass 5 when viewed from a plane. That is, the rear end of the T-shaped elastic sealant 11 is adhered to the outdoor end of the rib glass 13, and the end surfaces of the surface glass 5 adjacent to both side surfaces on the distal end side of the elastic sealant 11 are adhered. The indoor side end of the rib glass 13 is held by a glass edge member 17 via a seal member 19. The glass edge member 17 is fixed to the protrusion 15 a of the reinforcing member 15 with a bolt 21. As shown in FIGS. 3 and 5, the upper end of the rib glass 13 is held by the upper frame 7, and as shown in FIGS. 4 and 6, the lower end of the rib glass 13 is held by the lower frame 9.
[0013]
The reinforcing member 15 is made of a steel material, and supports the rib glass 13 against a force in the indoor or outdoor (depth direction) direction. The reinforcing member 15 is provided in the longitudinal direction along the indoor side edge of the rib glass 13, the upper part thereof is not connected to the frame and is free, and the lower end is formed in the vertical groove of the fastener 27. It is supported from the frame by the engaging bolts 28 and the weight receiver 29. The lower end of the rib glass 13 is placed on the lower frame 9.
[0014]
Here, the sliding structure of the upper frame 7 will be described with reference to FIGS. A rail member 33 having two guide grooves 31, 31 formed in parallel is fixed to the upper frame 7 by screws 32. These grooves 31 are formed along the longitudinal direction of the upper frame 7. A slider 36 fixed to the bracket 35 is engaged with the guide grooves 31, 31, and the bracket 35 is fixed to the frame by the fastener 25. Therefore, the upper frame 7 is slidable with respect to the frame in the longitudinal direction of the upper frame 7.
[0015]
Next, a fixing structure between the upper frame 7 and the reinforcing member 15 will be described. As shown in FIGS. 1 and 3, a bracket 37 is fixed to the upper part of the reinforcing member 15 by welding, and the bracket 37 is fixed to the upper frame 7 by bolts 39 and nuts 41. Since the upper frame 7 and the reinforcing member 15 are fixed as described above, the reinforcing member 15 can follow the movement of the upper frame 7.
[0016]
Next, the operation according to the present embodiment will be described. When a negative pressure or a positive pressure is applied to the indoor side of the surface glass 5 due to a pressure difference between the room and the outdoor or a wind pressure, the surface glass 5 tries to move to the indoor side or the outdoor side with respect to the negative pressure or the positive pressure. However, the rib glass 13 supports the surface glass 5 against this force. The strength of the rib glass 13 is enhanced by the reinforcing member 15. Further, since the reinforcing member 15 is fixed to the upper frame 7, the reinforcing member 15 can sufficiently support the surface glass 5 in the indoor and outdoor directions. On the other hand, when the upper frame 7 moves indoors or outdoors, the reinforcing member 15 moves following the upper frame 7, so that the rib glass 13 connected to the upper frame 7 and the reinforcing member 15 This prevents an excessive force from acting and prevents the rib glass 13 from being damaged.
[0017]
When the skeleton of the building is shaken due to an earthquake or wind, and a relative horizontal displacement occurs, a slider 36 fixed to the skeleton with respect to the upper frame 7 slides in the guide groove 31 and moves with respect to the upper frame 7. The skeleton moves in the left-right direction of the upper frame 7. In this case, the reinforcing member 15 is fixed to the upper frame 7 but is not fixed to the skeleton, so the reinforcing member 15 is provided together with the upper frame 7. Therefore, the reinforcing member 15 stays with the upper frame 7 with respect to the skeleton, so that only the skeleton moves with respect to the reinforcing member 15. Therefore, since the rib glass 13 has its exterior side fixed to the surface glass 5 and its interior side fixed to the reinforcing member 15, the rib glass 13 hardly changes in phase due to relative horizontal displacement. Damage can be prevented.
[0018]
FIG. 7 shows a modification of the connecting portion between the surface glass 5 and the rib glass 13. In this modified example, a panel mounting member 51 is provided on the indoor side between opposing ends of adjacent surface glasses 5, and the panel mounting member 51 holds the outdoor side of the rib glass 13. In the configuration shown in FIG. 7, the surface glass holding member 53 is engaged with the end of the adjacent surface glass 5 from the outdoor side of the surface glass 5, and the surface glass holding member 53 is locked to the panel mounting member 51. In this way, the surface glass 5 is prevented from shifting outward or coming off.
[0019]
The present invention is not limited to the above-described embodiment, and can be variously modified without departing from the gist of the present invention.
[0020]
For example, the sliding between the upper frame 7 and the frame may be configured such that the design groove 31 is provided on the frame side and the slider 36 is provided on the upper frame 7 side.
[0021]
