The glass G is fitted into this, and it is configured as one unit. The framework can be connected by a corner block as a well-known method.

The glass G is built in, for example, the Kendon system, and the pressing edges 34, 44 are provided from outside the left and right frame members 30, 40.
It is fixed by fixing with. As shown in the figure, the periphery of the glass G is held by each frame member by a setting block, a back support member, a front support member, and a seal material.

The curtain wall unit CU is unitized in advance at a factory, for example, and is carried into the site.

(Regarding the Fixing Structure of the Curtain Wall Unit) Next, the fixing structure of the curtain wall unit CU to the frame 1 will be described with reference to FIGS. 8 and 9 as well. It has mounting parts 33 and 43 that protrude, and angle-shaped mounting parts 2 and 2 are fixed to bolts 3 and 3 on its outer surface. On the other hand, a fixture 4 is buried in the frame 1 and a fastener 7 is fixed by a bolt 6, and the fastener 7 and the mounting fixtures 2 are respectively connected to bolts 8,8.
As a result, the curtain wall unit CU is fixed to the frame 4 as a result.

(About the airtight structure between the curtain wall units) Now, the curtain wall unit of the present invention, particularly the mutual airtight structure, will be described mainly with reference to FIGS.

The curtain wall unit CU of the present invention
Is, as shown in FIG.
In the embodiment, the molded seal member 51 and the molded seal member 52 are attached in advance only to the upper frame member 10 and the left frame member 30, and the molded seal members 51, 52 for one curtain wall unit CU. The mounting portion of the molded seal members 51 and 52 is the same as the mounting portion of the molded seal members 51 and 52 with respect to the other curtain wall units CU. But facing frame material of the adjacent curtain wall unit CU,
That is, in the embodiment, the lower frame member 20 and the right frame member 40 are brought into contact with each other to achieve airtightness.

According to this embodiment, when a molded seal member is attached to and fixed around the four circumferences of the curtain wall unit in a factory as in the prior art, the molded seal member is transported from the factory to the site (truck) prior to transportation. The curing time for preventing damage is substantially halved.

Further, even if the molded sealing members are not necessarily provided on the four circumferences of the curtain wall unit, the above-described embodiment can achieve sufficient airtightness. Accordingly, the number of members of the molded seal member is reduced by half, so that not only the cost is reduced, but also the labor required for mounting is reduced by half.

On the other hand, as shown in detail in FIGS. 1 and 2, the upper frame member 10 and the left frame member 30 of the curtain wall CU have the other curtain wall unit CU adjacent to the curtain wall unit at the indoor side portion. Overhang 1 protruding to the side
1 and 31, and molded seal members 51 and 52 are fixed to the overhang portions 11 and 31. Specifically, the fixing is performed by forming a lip groove and engaging the legs of the molded seal members 51 and 52.

On the other hand, the lower frame member 20 and the right frame member 40 of the other curtain wall unit CU have the above-described curtain wall unit C
The crimping portions 21 and 41 projecting toward the U side are formed, and the crimping portions 21 and 41 are configured to be crimped to the molded seal members 51 and 52.

Further, the crimping portions 21 and 41 are
Located on the outside of the room from the end of the crimping parts 21 and 41
The portions have a positional relationship of covering the distal ends of the overhang portions 11 and 31 as viewed from the outdoor side, that is, have a relationship of wrapping when viewed from the outdoor side. These crimping portions 21 and 41 and overhang portion 1
1, 31 by themselves and in combination constitute a water return that prevents the ingress of rainwater.

As can be inferred from FIG. 10 relatively easily, at the joint intersections of the four adjacent curtain wall units, even if sealing is performed by the molded sealing members 51 and 52, airtightness is slightly increased due to irregularities or the like. It is always difficult to achieve.

Therefore, as shown conceptually in FIG. 10 and shown in detail in the other drawings, the ends of four adjacent molded seal members are covered with a waterproof plate 80 from the indoor side to achieve airtightness. be able to.

In the upper frame member 10 of each curtain wall unit, a sealing member 61 for rain barrier is provided outside the molded sealing members 51 and 52, and the sealing member 61 for rain barrier is provided below the adjacent curtain wall unit. By configuring so as to be in contact with the frame member 40, it is possible to prevent rainwater from directly entering the joint intersection portion, and it is possible to reduce the burden of airtightness of the molded seal members 51 and 52.

The sealing material 61 for the rain barrier is shown in FIG.
And as specified in Figure 7, the vertical joint space Black

Similarly, a pressure-bonding sealing member 62 that is integrated on the rain barrier sealing material 61 by, for example, bonding is also straddling.

Further, on the lower surface of the rain barrier sealing material 61, as shown in FIG.
Hanging pieces 63B, 63A are formed integrally in the vertical joint space so as to sandwich the 40 staggered overhanging pieces 32, 42 from the indoor side and the outdoor side, respectively.

The waterproof plate 80 described above does not have form stability because contacting it with flexibility increases the water-tightness effect. Therefore, as particularly referred to in FIGS. 5 to 7, the waterproof plate 80 is inserted into the lip groove on the front surface of the holding piece 81, and these are attached to the above-mentioned mounting portions 33, 43 of the left and right frame members 30, 40. A groove is cut out at the boundary between the groove and the groove, and the groove is fixed by being fitted into the groove.

According to this embodiment, the sealing member 61 for the rain barrier, the pressure-sealing member 62 and the hanging pieces 63A, 63 are provided.
B blocks rainwater that intrudes into the joint intersection subspace deeper than B, and the rain is suitably performed.

Here, as the molded seal members 51 and 52, the rain barrier seal material 61, the pressure seal member 62 and the hanging pieces 63A and 63B, appropriate materials can be selected from the viewpoint of watertightness and airtightness. EPDM
(Ethylene / propylene dimer rubber), silicone rubber, chloroprene rubber, santoprene rubber and the like can be used.

(Form Having Cosmetic Cover) FIGS. 3 and 4 show an example in which a decorative cover 90 is provided on the vertical joint, and the decorative cover 90 is straddled over the outdoor surfaces of the left and right frame members 30 and 40. Is provided. As shown in FIG. 4, the decorative cover 90 has a fixed connecting member 91 at the upper part thereof.
And the fixing connection member 91 is fixed to the upper frame material 1.
The lower portion is locked on the upper portion, and the lower portion is fixed by engaging with the locking portion 91a.

(Form of Attaching Curtain Wall Unit in a Vertical Position) In the above embodiment, the curtain wall unit CU is provided with a mounting portion, and the curtain wall unit CU is fixed to the frame 1 via the mounting portion.

However, the curtain wall unit CU
Can also be fixed to the cubicle 100 fixed to the frame 1. This form is shown in FIG. 11 and FIG.

To describe this form, a rectangular cross section 100 is fixed to the frame 1 in the following form. That is, the fixture 4 is embedded in the frame 1, and the fastener 7 is fixed by the bolt 6. On the other hand, the box 100 is fitted with a box-shaped fitting portion 5A of the mounting bracket 5, and is fixed by bolts 3A. The wings 5B, 5B of the mounting bracket 5 and the fastener 7 are connected by bolts 8, 8, respectively, so that the curtain wall unit C
U is fixed to the frame 1.

Next, a detailed description will be given of a structure for attaching the curtain wall unit to the cubicle (support member) and a method of attaching the same.

That is, in the adjacent upper and lower curtain wall units CU, CU, a downward first engagement groove 20A is formed on the indoor side surface of the lower frame member 20 of the upper curtain wall unit CU, and the lower curtain wall unit CU is formed.

The second second engaging portion 72A is engaged.

The engagement connecting body 72 and the engagement support 71 are integrated by an integrating means, for example, a bolt nut 73, and the upper part of the lower curtain wall unit CU is erected.
00 is held.

11 and 12, the left and right curtain wall units are adjacent to each other and the upper and lower curtain wall units are adjacent to each other on the outdoor side of the cubicle 100. A pair of an engagement support 71 and an engagement connector 72 is provided on each of the left and right side surfaces, and the above-described mounting structure is adopted on each of the left and right sides of the cubic 100. Has been held. In this case, in the embodiment, the left and right engagement supports 71, 7
1 is fixed to the cubicle 100 in common by mounting bolts 75.

Further, referring to the drawings in detail, the engagement connecting body 72 has a first connecting portion 71B extending horizontally toward the indoor side by the first engaging portion 71A and horizontally disposed. The body 71 has a second connecting portion 72B extending horizontally to the indoor side by a second engaging portion 72A and horizontally disposed, and a locking portion 72C protruding upward into the indoor portion of the second connecting portion 72B. The engagement connecting body 72 and the engaging support body 71 are integrated by integrating the first connecting portion 71B and the second connecting portion 72B with a bolt nut 73, and in this state, The locking portion 72C faces the indoor side surface of the first connecting portion 71B.

While the first engaging portion 71A of the engaging support 71 is engaged with the first engaging groove 20A and fixed by fixing means, for example, fixing screws 74, the engaging connecting member 72 is fixed. The second engaging portion 72A is engaged with the second engaging groove 10A, and the second engaging portion 72A is relatively fixed without being fixed by the fixing means.
An engagement groove 10A is slidably engaged with the second engagement portion 72A.

Here, the reason why the second engagement groove 10A and the second engagement portion 72A are slidably engaged is to allow displacement between layers when it occurs. The reason why a slight clearance is secured between the end of the second engaging portion 72A and the groove bottom of the second engaging groove 10A is to absorb errors at the site and simplify the mounting work. .

In this embodiment, when the curtain wall unit CU is mounted, the engaging support 71 is fixed to the cubicle 100 by the mounting bolts 75, 75, and is fixed to the first engaging portion 71A of the engaging support 71.
