Description

[Detailed description of the invention] [Industrial application field] This invention relates to the mullion part of horizontal windows in architectural structures, and is particularly used for curtain walls etc. using panels on the outer wall.

[Conventional technology]

For example, there are windows shown in FIGS. 10 and 11 as common horizontal windows in building construction. In this example, a sash 43 formed into a rectangular frame by upper and lower frames and left and right vertical frames or mullions is built into the opening between the upper and lower panels 41 constituting the curtain wall.

In this case, the satsushi 43
The clearance is the width of the joint 44.

[Problem that the invention attempts to solve]

However, in the case of a conventional sash frame built later, the sash 43 deforms during an earthquake, making it difficult to follow the interstory displacement of the building.

In addition, when installing mullions between the upper and lower frames of consecutive windows, whether the mullions are fixed directly to the upper or lower frames or fixed to the upper and lower panels via mounting brackets, large inter-story displacements occur in the building during an earthquake. When this occurs, it is difficult to follow this. That is, since there is a limit to the deformability of the mullion, there is a risk that the mullion mounting portion may be damaged or destroyed due to interlayer displacement.

The mullion part of the continuous window of this invention is intended to solve the above-mentioned problems.

[Means for solving problems]

In this invention, a fin-like piece 3b protruding toward the indoor side is formed on the mullion 3 having a hollow cross section in the mullion attachment part of the continuous window provided between the upper and lower panels 1 constituting the outer wall surface of the building, and the fin-like piece 3b The upper and lower ends of the brackets 6 and 7 projecting from the upper and lower panels 1 and the clamping pieces 8 are inserted from both sides, and are supported by tightening bolts 9 passing through these.

The surfaces of the brackets 6, 7 and the clamping piece 8 that come into contact with the fin-like piece 3b are formed into convex curved surfaces, so that even when they are fastened with the tightening bolts 9, they are protected against inter-story displacement of the building during an earthquake. , the mullion 3 is inclined along a curved surface to prevent undue force from acting on it. Furthermore, by forming the convex curved surface on the bracket side on the bracket itself, the number of parts for installation can be reduced, and connection work using bolts can be facilitated.

If the upper and lower frames 4 and 5 of the continuous window are integrated into the upper and lower panels 1, the brackets 6 and 7 will be fixed to the upper and lower frames 4 and 5. Furthermore, the upper and lower brackets 6 and 7 are, in principle, mounted on the same side.

The mullion 3 is provided inside the indoor side surface of the glass panel 2 of the continuous window, and a sealing material 18 or an elastic material such as synthetic rubber is attached to the end of the glass panel 2 longitudinally to the outdoor side surface of the mullion 3. By closely supporting the support member 28, the mullion 3
It does not appear on the surface of the continuous windows, giving it a clean and clear appearance. In addition, the glass panel 2
It is possible to slide the

〔Example〕

Next, the illustrated embodiment will be described.

Fig. 2 shows an overview of the building, and Figs. 7 to 9 show an outline of the structure of the building, in which horizontal windows are formed between panels 1 that make up the outer wall of the building. The panel 1 in this embodiment is a precast concrete panel, and is fixed to a floor slab 32 of a building frame via fasteners 34 and 35.
It makes up the curtain wall.

The upper frame 4 and the lower frame 5 constituting the window frame are the lower end surface of the upper panel 1 and the lower panel 1, respectively.
is attached to the top surface of the These upper and lower frames 4 and 5 are integrally hammered in advance when the panel 1 is manufactured.

FIG. 1 shows an example of the mullion mounting part of this invention, and FIGS. 5 and 6 show a longitudinal section and a transverse section, respectively, in the direction in which the continuous windows are expected.

The mullion 3 consists of a hollow base 3a and a fin-like piece 3b that protrudes toward the indoor side, and the upper and lower ends of the fin-like piece 3b are sandwiched between the upper and lower brackets 6, 7 and the holding piece 8, and the fin-like piece 3b is inserted through these. It is fastened by tightening the tightening bolt 9.

The upper bracket 6 consists of a base piece 6a and a hanging piece 6b, and the base piece 6a is attached to the upper frame 4 with screws 11.
It is fixed to the base 4a of. The portions of the hanging piece 6b and the clamping piece 8 through which the tightening bolt 9 passes are formed into convex curved surfaces, and are in contact with the fin-like pieces 3b of the mullion 3 at the curved surfaces.

This allows the mullion 3 to tilt with respect to relative displacement in the horizontal direction with respect to the lower end. In addition, 10a in the figure
is a washer, and 10b is a spring washer.

Similarly, the lower bracket 7 consists of a base 7a and a rising piece 7b, and the rising piece 7b and the clamping piece 8 form a mullion 3.
The curved surface contacts the lower end of the fin-like piece 3b, and is fastened with a tightening bolt 9.

Furthermore, a mullion cover 13 is attached to the indoor side of the mullion 3 as a decorative material.

Figure 2 schematically shows the function of the mullion part of this invention. When a relative displacement occurs between the upper and lower panels 1 during an earthquake, the mullion 3 moves into the brackets 6 and 7.
It is also inclined along the convex curved surface of the holding piece 8, so that deformation of the mullion 3 can be suppressed.

In this case, it is desirable that the upper and lower brackets 6 and 7 be attached to one side (in the case of the figure, the panel on the right side of the joint position between the panels).

As shown in FIG. 5, the upper and lower ends of the glass panel 2 of the continuous window are covered with sealing material installed between the hanging piece 4b or the rising piece 5b of the upper and lower frames 4, 5 and the ridge 12 through a backing material or the like. The material 14 is filled.

Further, reference numeral 21 in the figure represents a tile fixed to the surface of the panel 1.

Further, in this embodiment, each mullion 3, 3a, 3b is located inside the indoor side surface of the glass panels 2, 2a, 2b, so that the mullion 3 does not appear on the outside surface of the window room.

With this configuration, the glass panel 2 slides within the upper and lower frames 4 and 5 in response to interstory displacement during an earthquake, and the sealing material 17 between the glass panels 2b deforms to a certain extent, which has the function of suppressing the amount of displacement. ing. Furthermore, regarding the relationship between the mullion 3b and the glass panel 2b, the indoor side surface of the glass panel 2b is adhered to the outdoor side surface of the mullion 3b with a sealant 18, and the relationship between the upper frames 4 and 5 and the glass panels 2a and 2b is The space between them is filled with sealing material 9 as described above to fix the glass panels 2a and 2b.

The L-shaped glass panel 2a at the corner is made of two glass panels abutted at right angles and glued together with a sealant 16, as shown in the figure, and the edges on both sides are made of elastic panels attached along the longitudinal direction of the mullion 3a. It is supported by a support member 28. The elastic support member 28 is made of highly elastic synthetic rubber such as silicone rubber, aluminum profile, plastic, wood, etc., and a sealing material 15 is filled between it and the side edge of the L-shaped glass panel 2a.

Further, the upper and lower ends of the bent top of the L-shaped glass panel 2a are supported by locking elastic blocks 29 provided within the upper and lower frames 4 and 5. The locking elastic block 29 is made of synthetic rubber such as EPT (ethylene propane terprimer), and instead of sliding the L-shaped glass panel 2a against interlayer displacement, the locking elastic block 29 is used as the center of rotation by elastic deformation. This prevents damage to the L-shaped glass panel 2a.

[Effect of the invention] The mullion is provided with fin-like pieces, and the upper and lower ends of the fin-like pieces are supported by being sandwiched between curved surfaces from both sides.
The mullion can be tilted to cope with the displacement of the building's floors during an earthquake. That is, since the mullion can be tilted along the curved surface, no unreasonable force is applied to the mullion and the mullion mounting portion, thereby preventing damage or destruction of the members.

The structure is simple, and the installation work on site is just tightening bolts to the bracket, so the work is simple and easy to install.

Because the structure supports the side edges of the glass panel by longitudinal elastic support members provided on the outdoor side of the mullion, the side edges of the glass panel can be easily maintained even when the mullion, which has a hollow cross section that is difficult to deform, is tilted. It is possible to elastically support the glass panel and allow the glass panel to slide laterally in response to interlayer displacement of the building, thereby preventing damage to the glass panel and sealing material.
