Description

Description: TECHNICAL FIELD The present invention relates to a mounting structure of a unitized plate-shaped member, and more specifically, it is publicly used for an outer wall structure such as a curtain wall wall mounting body. The present invention relates to a mounting structure of a plate-shaped member which is unitized and can be manufactured.

[Prior Art] In recent years, many buildings having a so-called curtain wall wall covering as an outer wall have been found.

FIG. 2 and FIG. 3 show a conventional example of a structure for attaching a plate-like member such as a unitized plate glass material applied to such a curtain wall wall body to the body side.

Of these, FIG. 2 shows that the mounting member 2 made of a hollow frame member is fixed to the four circumferences of the back side edge of the plate-like member 1 through the structural adhesive 4 to form a unit, which is attached to the body side. FIG. 3 shows a conventional example in which a fixing member 6 such as a bolt is attached to a fixed base material 5 such as a cube, of which (a) has a flat cross-section structure and (b) has a vertical cross-section. The structures are shown respectively.

The mounting member 2 in this example has a space portion 3 having a relatively large cross-sectional area, and by using this space portion 3, the fastening work of the fastening member 6 such as a bolt to the base material 5 can be performed. Since it can be performed, it has excellent workability.

Further, FIG. 3 shows a unit in which the plate-shaped member 1 is unitized by fixing the mounting member 2 to the back side edge portions located on the left and right of the plate-shaped member 1 via the structural adhesive 4 and arranging them side by side in the left-right direction. For each mounting member 2 of the converted plate-shaped member, a common locking portion piece 8 separately attached to a concealing material 7 fixed to a base material 5 such as a cube fixed to the body side is interposed. FIG. 2 shows a conventional example in which the individual plate-shaped members that are vertically adjacent to each other are locked together and are continuously attached via the eye-free member 9.
Among them, (a) shows a plane sectional structure and (b) shows a longitudinal sectional structure.

2 and 3, reference numeral 26 is a backup material and 63 is a sealing material.

[Problems to be Solved by the Invention] By the way, in the case of the conventional structure shown in FIG. 2, the mounting member 2 itself made of the hollow frame material is excellent even if it is excellent in the site workability as described above. Since it is large and heavy, it is difficult to handle, and there is not only the inconvenience that the workability at the time of fixing to the plate-shaped member 1 by the structural adhesive 4 deteriorates, but also the unitized plate-shaped member is stored or transported. There was also a problem that the overall cost would rise, such as the cost for this was higher than before.

In the case of the conventional structure shown in FIG. 3, one unitized plate-shaped member 1 is vertically positioned on the shared locking portion piece 8 on the body side by interposing the mounting member 2 therebetween. Besides, it is necessary to engage the other common plate-like members 1 that are adjacent to each other in the left-right direction with respect to the same shared locking piece 8. . For this reason, not only the positioning in the vertical direction is necessary, but also the positioning in the lateral direction must be used, resulting in poor workability.
Furthermore, since the shared locking piece 8 is an independent member, it is necessary to attach it to the body side by a separate operation,
There was also the inconvenience that the work man-hour increased by that much.

Moreover, in the case of the conventional structure shown in FIG. 2 and FIG. 3, there is a problem that it is not always possible to exhibit a preferable absorption performance for interlayer displacement caused by an earthquake or the like.

[Means for Solving the Problems] The present invention has been made in view of the above problems of the prior art, and its structural feature is a plate-shaped member made of a plate glass material or the like, and at least the plate-shaped member. This interposition member includes an attachment member that is fixedly arranged along a back edge of one side and that is fixed via a fixing layer, and an interposition member that is interposed between the attachment member and the body side. And uniting by combining the recesses of the mounting member with each other, the unitized plate-shaped member is fixedly arranged on the base material on the skeleton side in correspondence with the respective interposing members. This is because the negative pressure receiving member is attached to the body side by freely connecting the free movement in the out-of-plane direction.

[Operation] For this reason, the unitized plate-shaped member is out-of-plane with respect to the negative pressure receiving member fixedly arranged on the base material on the body side in correspondence with the interposing member that constitutes the unit. Since it is possible to freely connect the unidirectional movements and attach it to the body side, it is possible to exert a good absorption performance against the interlayer displacement caused by an earthquake or the like.

Moreover, since the interposing member that constitutes the unitary plate-shaped member can be exposed and arranged on the indoor side,
By finishing the exposed surface itself in advance, it is possible to finish the work without installing new finishing materials such as decorative covers and decorative attachments, and it is possible to reduce the number of construction man-hours and the number of used parts. it can.

[Embodiment] An embodiment of the present invention will be described below with reference to the drawings.

According to FIG. 1 showing an embodiment of the present invention, a plate-shaped member 11 made of a plate glass material and at least one back side edge portion of the plate-shaped member 11, preferably the right and left opposing surfaces of the plate-shaped member 11. A mounting member 12 that is arranged along two dorsal edges and is fixedly arranged via a fixing layer 25 formed by using a fixing agent having an appropriate composition such as a structural adhesive made of a silicone sealant.
And the interposing member 31 disposed between the mounting member 12 and the body side are separately formed by combining the interposing member 31 and the recesses 37 and 15 of the mounting member 12. A unitized plate member is used. Incidentally, the fixing layer 25 can be formed only by a fixing agent having the same component such as a structural adhesive or the like, and a backup material made of silicone rubber or other plastic or rubber in the central portion as shown in the figure. It can also be formed by sandwiching 26.

Of these, the mounting member 12 includes the horizontal portion 22 and the horizontal portion 22.
The upper surface of 22 has a pair of wing-shaped protruding members 23, 23, and a recess 15 is provided between each protruding member 23 and the horizontal portion 22.
Are formed.

Further, the interposition member 31, which is freely combined with and disengaged from the mounting member 12, has a recessed portion 37 defined by a pair of holding portions 36, 36, and, for example, FIG. In (a), a positioning projection piece 45 is continuously provided on the side of the holding portion 36 on the left side of the interposition member 31 located on the left side. A cutout portion 46 is provided on the surface of the interposition member 31 facing the body side so that the negative pressure receiving member 57, which will be described later, can be inserted freely.

On the front side surface of the base material 51 such as the cube on the side of the body to which the unitary plate-shaped member having such a structure is to be attached, a support piece portion 54 is provided at the center thereof so as to project. A pair of protrusions 55, 55 each having an outwardly bent locking portion 56 at its tip end are arranged in parallel on both sides of the support piece 54 at a predetermined distance. The supporting piece portion 54 and the projection portion 55 form the receiving member support portion 53.

Further, with respect to the receiving member support portion 53 formed on the base material 51 in this manner, the negative pressure receiving member 57 for absorbing the negative pressure acting in the direction of separating from the body side to the outside is separately provided. It is connected and arranged.

In this case, each of the negative pressure receiving members 57 includes a bent portion 58 capable of engaging with the locking portion 56 of the one projection 55 that constitutes the receiving member support portion 53, and the support piece. The fixed portion 59 arranged along the portion 54 and the cutout portion 46 provided in the one interposition member 31 are inserted, and the cutout portion 46 is interposed via the upper cutout edge 47. The mounting member 31 itself is placed, and a supporting portion 60 for supporting the mounting member 31 is provided, and a locking portion 61 that is fixed to a projecting end of the supporting portion 60 and locks the interposing member 31 in a difficult manner to pull out. It is formed integrally.

The locking portion 61 in this case is wider than the lateral width of the cutout portion 46 of the interposition member 31, but is wider, and moreover, the cutout portion 46.
Although it is slightly lower in height than the vertical width thereof, it is formed with a protruding crown portion 61a.

The unitary plate-shaped member thus configured has a base material on the body side in the notch 46 of the interposition member 31.
The support portion 60 of the negative pressure receiving member 57 fixedly arranged on the 51
The locking part 61 and the locking part 61 are inserted and locked so that they cannot be pulled out easily, so that they can be attached to the body side.

In the figure, reference numeral 62 is a molded sealing material, and 63 is a sealing material.

Since the present invention is configured in this way, the unitized plate-shaped member is combined with the mounting member 12 by interposing the pair of holding portions 36, 36 and the positioning protrusion 45. The engaging portion 61 fixed to the projecting end of the supporting portion 60 on the negative pressure receiving member 57 side is introduced into the cutout portion 46 of the mounting member 31, and the cutout portion 46 is formed as shown in FIG. The interposition member 31 itself is supported by the upper cutout edge 47 that defines the
It can be attached to the side of the base material 51 by placing it on the side of and supporting it.

In this case, the locking portion 61 on the side of the negative pressure receiving member 57 has the crown 61a at the upper cut edge 47 of the cut portion 46 of the interposition member 31.
Since it can be positioned so as to project above, even if negative pressure on the side of the plate-shaped member unitized may act, the interposition member 31 can be moved along the support portion 60. The upper notch edge 47 of the notch 46 can be
By engaging with, the crown 61a of the locking portion 61 can function as a stopper, and therefore, it is possible to exhibit good absorption performance even for interlayer displacement in the out-of-plane direction caused by an earthquake or the like. it can. Further, since the interposition member 31 forming the unitized plate-shaped member can be exposed to the inside of the room, a new decorative cover or decorative attachment can be newly formed by pre-finishing the exposed surface itself. It is possible to finish the work without attaching finishing materials such as, and it is possible to reduce the number of construction man-hours and the number of used members.

[Effects of the Invention] As described above, according to the present invention, the unitary plate-shaped member is fixedly arranged on the base material on the skeleton side so as to correspond to the interposing member constituting the unit. Since each of the negative pressure receiving members can be freely connected to the free movement in the out-of-plane direction and attached to the skeleton side, good absorption performance can be exhibited against interlayer displacement generated by an earthquake or the like.

Moreover, since the interposing member that constitutes the unitary plate-shaped member can be exposed and arranged on the indoor side,
By finishing the exposed surface itself in advance, it is possible to finish the work without installing new finishing materials such as decorative covers and decorative attachments, and it is possible to reduce the number of construction man-hours and the number of used parts. it can.
