Description

[Detailed description of the invention] [Industrial application field] This invention relates to a heat insulating curtain wall.

[Conventional technology]

The mullions and mullions of the curtain wall are made of metal such as aluminum profiles, and conduct heat very well, so in winter, the heat from the warm indoor air can easily travel through the mullions and mullions and escape into the outside air. On the other hand, in the summer, the cold air inside the room is easily warmed by the warm outside air, which inevitably reduces the heating and cooling effect by half.

Additionally, in winter, condensation could form on the mullions and the inside of the room, making it dirty.

Recently, in order to solve this problem, it has become necessary to form mullions and grids into two parts, indoors and outdoors, and to interpose a heat insulating material such as urethane resin between the indoor and outdoor materials. Mulled or mullioned shapes that are integrally formed are widely used. For example, it has been proposed in Japanese Utility Model Application Publication No. 60-84689 and Japanese Utility Model Application Publication No. 56-76816.

[Problem that the invention attempts to solve]

However, conventional mullions and mullions of this type,
Part of it is made of insulation material, so
The disadvantage was that the overall strength of the mullion and mumu was weak, and it was also extremely vulnerable to fire.

Furthermore, since the entire mullion and the mullions are configured to come into contact with each other, heat conduction occurs between these members, making it impossible to completely insulate them.

This invention was proposed in order to solve the above-mentioned conventional problems, and the purpose is to provide an insulating curtain wall that has an extremely high insulation effect and is also extremely strong. It is.

[Means for solving problems]

The insulating curtain wall of this invention is made of mullion 1
A mullion body 5 integrally formed with

The end portions of the webs 6b protruding toward the indoor side of the mullions 6 are connected via the blocks 7, and the mesh main body 8, in which the mesh 2 is integrally formed, is shaped like a flat plate and has a hook-shaped portion 9a at its upper end. Consisting of the formed blind cover 9, the blind main body 8 and the blind cover 9
The key-shaped parts 9a are connected via the heat insulating block 16, attached to the crosspiece member 14 at the protrusion 9b on the lower side of the blind cover 9, and the blind main body 8 is connected to the left and right mullions 1, 1. Notches 11, 11 are provided so that both ends thereof do not come into contact with the mullions 6, 6, and lip grooves 6d, 9c are provided on the indoor sides of the mullions and the blind cover 9. The above object is achieved by attaching the gasket materials 22 and 23 to the gasket 9c in a state in which they are in contact with the open body 8 and the face material 3.

〔Example〕

Hereinafter, this invention will be explained with reference to an embodiment illustrating the invention.The insulating curtain wall A is constructed by vertically erecting a plurality of mullions 1, 1 at regular intervals in the lateral direction. Multiple mumu in between 2,2
are constructed in a balanced manner at regular intervals in the vertical direction, and a paneling material 3 or a swinging shoji door 4 is built into each opening B composed of the left-right direction 1, 1 and the upper and lower no-mume 2, 2. has been done.

The mullion 1 is divided into indoor and outdoor parts, including a mullion main body 5 on the indoor side and a mullion shape member 6 on the outdoor side.

Further, the mullion main body 5 has a web portion 5b vertically protruding from the outdoor side of the base portion 5a having a rectangular hollow cross-sectional shape, and a flange portion 5c at the tip of the web portion 5b.
The mullion shaped member 6 has a web portion 6b, on the indoor side of a flat base portion 6a.
6b are provided to protrude in parallel, and flange portions 6c, 6c are provided to protrude from the tips of the web portions 6b, 6b.

Further, lip groove portions 6d, 6d are formed at one end of the flange portions 6c, 6c.

The mullion body 5 and the mullion shape member 6 formed in this way
A heat insulating block 7 made of a hard synthetic resin material or the like is installed between both flanges 5c and 6c.
The mullion 1 is constructed by overlapping the two parts with each other interposed therebetween and connecting them together by screwing them with a plurality of connecting screws 7a, 7a.

The blind 2 is formed on the indoor side into a blind main body 8 and a blind cover 9, which are divided into indoor and outdoor parts.

The open body 8 has a hollow cross-sectional shape, and its upper side is formed in a stepped shape that gradually slopes downward from the indoor side to the outdoor direction, and the lower side slopes gradually upward. A protrusion 10 is formed in a stepped shape and has an L-shaped cross section (see FIG. 2) or a T-shaped cross section (see FIG. 3) at the outdoor end of the blind main body 8. It is formed continuously in the longitudinal direction.

Notches 1 are provided at both left and right ends of the protrusion 10.
1 and 11 are formed (see FIGS. 2, 3, and 6).

The eyeless main body 8 formed in this manner is installed horizontally between the left and right mullion main bodies 5, and its both ends are screwed to the web portion 5b of the mullion main body 5 using a connecting fitting 12 and a connecting screw 13. (See Figure 3). In such a case, the notches 11, 11 are formed at both left and right ends of the protrusion 10, and the gasket material 22 is attached to the lip groove 6d of the mullion 6, so that the gapless body 8 and the mullion The structure is such that metal contact with the profile 6 can be avoided and heat conduction between these members can be completely blocked.

The blind cover 9 is formed into a horizontally long flat plate shape. A hook-shaped portion 9a is formed at the upper end of the blind cover 9, and a protruding piece 9b is formed at the lower end. Further, a lip groove portion 9c is formed on the indoor side of the hook-shaped portion 9a of the partially blind cover 9 (see FIGS. 2 and 3). Such a blind cover 9 has upper and lower blind bodies 8, 8 of the opening B into which the face material 3 is fitted.
It is installed on the outside of the room.

In the blind cover 9 formed in this way, the lower protruding piece 9b is screwed to a crosspiece member 14 such as a ridge member (to be described later) with a mounting screw 15, and the upper end hook-shaped portion 9a is attached to the rising portion 10a of the protruding portion 10. Insulation block 1
6 (see FIGS. 2 and 3), or by hooking it to a hook 17a of a blank member 17 (described later) screwed to the upper end of the blank main body 8 (second (See figure) It is attached to the outdoor side of the eyeless main body 8.

Therefore, Mume 2 is configured.

Further, both ends of the blind cover 9 are fitted into the left and right recesses 6e, 6e of the mullioned member 6 to prevent a connecting portion, thereby preventing rainwater from entering from these portions and improving the design.

Furthermore, a blind member 17 is screwed to the upper end of the blind main body 8 of the opening B in which the swinging shoji door 4 is installed, with a mounting screw 15 located on the outdoor side. A heat insulating block 7 made of a hard synthetic resin material or the like is interposed between the open section 17 and the open body 8 to prevent metal contact, and completely blocks heat conduction between these members.

Similarly, a vertical frame 18 having a rectangular hollow cross section is installed inside the left and right mullioned bodies 5, 5 of the opening B.

The swinging shoji door 4 is constructed by assembling upper and lower horizontal frames 4a, 4a, left and right vertical frames 4b, 4b into a substantially rectangular frame, and doubly fitting face materials 4c, such as glass, into this frame. It is configured.

The swinging shoji door 4 is rotatably installed between the upper and lower blind bodies 8, 8 of the opening B, around a rotating shaft 19, and is configured to be able to be opened and closed freely (see FIG. 2).

Further, between the upper and lower horizontal stiles 4a, 4a and the left and right vertical stiles 4b, 4b of the swinging shoji door 4, and the upper and lower blinds 2, 2 and the left and right mullions 1, 1, thermal insulation tight materials 20, 20 are installed.
are interposed in a double manner, and the insulation, airtightness, and watertightness of the periphery of the shoji door 4 are achieved. The heat insulating tight materials 20, 20 are attached by opening one end thereof and fitting them into lip grooves 4d, 4d formed on the outer peripheries of the upper and lower side frames 4a, 4a and the left and right vertical frames 4b, 4b of the shoji door 4.

The face material 3 is fitted into the opening B in a double manner. The upper end of the panel 3 is fixed by the hanging part 8a of the blind main body 8 and the crosspiece member 14, the lower end is fixed by the rising part 8b of the blind main body 8 and the blind cover 9, and further The left and right edge portions are firmly fixed by the mullion member 6 and the rim member 21.

In such a case, the gasket material 23 is interposed continuously with the gasket material 22 between the peripheral edge of the face material 3 and the blind cover 9 and the crosspiece member 14, thereby improving the heat insulation, airtightness, and It is designed to be watertight. The gasket material 23 is the open cover 9
It is attached by fitting into the lip groove 9c of the cross member 14 and the lip groove 14a of the crosspiece member 14.
(See Figure 3).

In addition, a hollow connecting pipe 6e is arranged in a hole 6d formed in the connecting part of the mullion 1 and the open cover 9 between the hollow section C of the section 6 of the mullion 1 and the hollow section D of the section 2. (See FIG. 8), and these hollow portions C and D are connected to the outside air through a gap between the connection portion between the mullioned member 6 and the blind cover 9. Thereby, since the hollow parts C and D and the hollow parts C and D are in an equal pressure state with the outside air, it is possible to prevent rainwater from entering.

[Effect of idea]

Since this invention has the above configuration, it has the following effects.

Since the structure is such that insulation is performed at the outdoor end of the mullion body and the mullion body, even if the cross-sectional size of the mullion and the mullion body is slightly reduced, it is still possible to insert insulation material in the middle of the mullion and the mullion body. It has the same strength as conventional insulating curtain walls, and has an extremely high insulation effect.

In addition, the insulation blocks are interposed between the mullion body and the mullion cover, and between the mullion body and the mullion cover, so that they do not bear any substantial load, so even if there is a fire, the curtain wall It does not cause any damage to the whole body and has excellent fire resistance.

Since the mullion body and the mullion body are integrally formed, there is no drainage path that is likely to form at the boundary with the insulation material such as a mullion with insulation material interposed in the middle, and water leakage from this part is prevented. It can also be prevented.

When connecting the mullioned body to the left and right sides, provide a notch in the mullioned body so that both ends of the mullioned body do not come into contact with the mullioned body, and attach gasket material to the lip groove of the mullioned body. Therefore, the open body and the mullioned member are isolated by the gasket, thereby avoiding metal contact between the two members, and completely blocking heat conduction between these members.
