[0001]

[Industrial applications]

 This proposal relates to a mounting structure with interlayer displacement absorbing device for various window panels in a building curtain wall or the like.

[0002]

[Prior Art]

 Conventionally, for example, as a mounting structure with an interlayer displacement absorbing device for a window sash in a window mounting opening of a building exterior wall, the window sash mounting brackets are fixed to the upper and lower layers of the window mounting opening, respectively, and each bracket tip is fixed. Of the upper frame and lower frame of the window sash, and the mounting arms are respectively screwed to the upper and lower frames of the window sash, and the ends of the arms are horizontally extended to the inside of the room. The horizontal parts of the upper and lower brackets with the slide plates of Teflon sandwiched between them, and through bolt holes through the long holes provided in the horizontal parts of the arm parallel to the interlayer displacement direction. When both horizontal parts are connected, and when an interlayer displacement occurs between the upper and lower layers of the opening due to an earthquake or the like, the interlayer displacement is caused by sliding between the horizontal parts by the slide plate. Having a structure which is adapted to absorb is known.

[0003]

[Problems to be solved by the device]

 However, in the above conventional structure, the initial friction at the time of starting is large in the sliding contact between the slide plate and the horizontal portion, and the weight of the window sash is added in the direction of pressing the slide plate and the horizontal portion. As a result, the sliding force cannot be immediately generated in response to the occurrence of interlayer displacement, and the interlayer displacement can hardly be absorbed. The purpose of this plan is to eliminate the conventional drawbacks.

[0004]

[Means for Solving the Problems]

 As a means for solving the above problems, the present invention proposes that, in a window panel mounting opening formed between an upper layer portion and a lower layer portion of a building, the lower end portion of the window panel is fixed to the lower layer portion of the window panel. The bracket fixed to the upper layer has a horizontal smooth running surface to support the weight substantially, and the upper end of the window panel has a plurality of rollers rolling in the horizontal displacement direction on the horizontal plane and holding it by itself. An inter-layer displacement absorbing device for a window panel in a building, in which the bracket and the upper end of the window panel are connected so as to be relatively displaceable in the inter-layer displacement direction in a state where the traveling surface is in rolling contact with the roller. Propose a mounting structure.

The “window panel” in the present invention includes various other things such as a sash having a shoji that can be opened and closed, a fitting sash, a transparent or opaque panel, a unit panel, and the like. An embodiment of the present invention will be described below with reference to the drawings.

[0006]

【Example】

 In FIG. 1, an opening (S) for installing a window panel is provided between an upper horizontal member (1) made of hollow steel horizontally fixed to a building frame and a lower horizontal member (2) similarly fixed horizontally. In this opening (S), a window frame including upper and lower frames (4) and (5) and left and right vertical frames (6) (one vertical frame is not shown) is formed in the opening (S). A glass fitting window sash (3) fitted with glass (7) is attached by an attachment structure with an interlayer displacement absorbing device.

The mounting structure with the interlayer displacement absorbing device is as follows. First, a plurality of angled lower sash mounting lower layer brackets (8) are welded to each other at their bases on the indoor side surface of the lower layer horizontal member (2) at a distance from each other, and each bracket tip is attached. Is formed in a horizontal part (9) extending into the opening (S), and the lower frame (5) of the window sash (3) is placed on the horizontal part (9) of the bracket, and The lower frame (5) and the bracket (8) are connected to each other by bolts (11) and nuts (12) whose heads are engaged with the grooves (10) having a lip formed on the lower surface of the frame (5), whereby the above Almost the entire weight of the window sash (3) is supported by the lower girder bracket (8).

On the other hand, a plurality of angle-shaped sash mounting upper-layer girder brackets (13) are spaced apart from each other on the inner surface of the upper-layer cross member (1), and a plurality of bolts are provided at each base. (14), and at the same time, the front end of each bracket is formed in a horizontal part (15) extending into the opening (S), and the bottom surface of the bracket horizontal part (15) is provided with the window sash (3). The upper surface of the upper frame (4) was brought into contact with the roller plate (16) and the traveling plate (17) by sandwiching it, and the head was engaged with the groove (18) with a lip formed on the upper surface of the upper frame (4). The upper frame (4) and the bracket (13) are connected by bolts (19) and nuts (20).

As shown in FIGS. 4 and 5, the roller plate (16) has two elongated plate-shaped roller holding plates (22) and (22) on a flat rectangular base plate (21). Fixed in parallel with screws (23) and (23) at both ends, and each roller holding plate (22) has a horizontally long groove with a trapezoidal cross section, and the short upper side of the trapezoid holds the wrinkle inside. Roller holding grooves (24) ... Opened (25) on the upper surface of the plate (22) are formed in parallel with each other at a small interval in the longitudinal direction of the holding plate, and these roller holding grooves (24). Rollers (26) are respectively arranged between the base plate (21) and the base plate (21) so that they can be rolled while the outer peripheral portions of the rollers (26) are partially projected onto the holding plate (22). It is held. (27) is a bolt through hole provided in the center of the base plate (21).

As shown in FIG. 3, the traveling plate (17) has a horizontal smooth traveling surface (17 ') having a width in contact with the two rows of rollers (26), ... (26) of the roller plate (16). There is a long hole (28) in the center. The horizontal portion (15) of the bracket (13) is also provided with an elongated hole (29) parallel to the displacement direction between layers (see FIG. 2). The roller plate (16) as described above is screwed to the upper frame (4) of the window sash also with the screws (23) ... in the state where the two roller rows are directed in the interlayer displacement direction. , The traveling plate (17) is abutted on each of the rollers (26) with the long hole (28) of the traveling plate (17) oriented in the interlayer displacement direction. 15) are piled up, and the bolt (19) is inserted into the bolt through hole (27) of the roller base plate (21), the long hole (28) of the running plate (17) and the long hole (29) of the bracket horizontal portion (15). Then lightly tighten with a nut (20).

Now, when an interlayer displacement occurs between the upper horizontal member (1) and the lower horizontal member (2) due to an earthquake or the like, the lateral displacement of the lower horizontal member (2) is transmitted to the window sash (3), The lateral displacement of the upper cross member (1) is not transmitted to the window sash (3) by rolling of the rollers (26) through the running plate (17). In this case, since the weight of the window sash (3) is barely applied to the contact surfaces of the rollers (26) ... and the running plate (17), it quickly responds to the displacement of the upper cross member (1) and starts rolling lightly at the time of starting. To do.

[Effect of the device]

 Due to the installation structure of the inter-layer displacement absorbing device for the window panel in the proposed building, the upper end of the window panel and the bracket fixed to the upper layer are in rolling contact with each other through the rollers, which facilitates a light running displacement at the time of starting. Moreover, since the weight of the window panel is hardly applied to the rolling contact surface with the roller, the rolling of the roller is always light, and when an interlayer displacement between the upper and lower layers occurs due to an earthquake or the like. The displacement can be absorbed immediately in response to this.
