JPS5846171Y2 - Rain closing structure at the blind end of curtain wall - Google Patents

Description

[Detailed explanation of the invention] This invention is a curtain that has a shape of a mullion and a frame arranged between adjacent mullions, and is composed of a mullionless body and a mullion cover. This relates to a rain cover structure at the blind end of a wall.

Conventionally, in this type of rain protection, a method has been adopted in which an irregularly shaped sealing material is filled between the blind end and the mullion.

However, this method requires skill to fill with the irregularly shaped sealing material, and there is a risk of poor water retention due to peeling of the sealing material due to thermal expansion and contraction of the open material, aging deterioration of the sealing material due to sunlight, etc.

This idea was developed in consideration of the above circumstances, and it uses a molded elastic backing made of synthetic rubber or synthetic resin instead of an amorphous sealing material, making it easier to install on-site. It is an object of the present invention to provide a rain cover structure that effectively establishes a waterproof connection with the end of the eye.

The structure of this invention will be explained below based on the drawings.

1 to 7 show a first embodiment of this invention, in which a mullion 1 is attached to a mullion main body 1a and a mullion auxiliary frame 1b installed along a groove 1a'. This shows the case where the

This mullion auxiliary frame 1b is fitted and fixed to the mullion main body to form a mullion together with the mullion main body.

Reference numeral 2 is open, and the installation of the mullion is made up of an open main body 2a whose end is swallowed in a groove 1a' and an open cover 2b disposed on the outdoor side of the main body 2a.

3 is a surface material such as glass, which is fitted into the frame formed by the mullion 1 and the mullion 2; After the mounting provided on the main body 2a is fitted into the groove 2a', the mounting is performed by connecting the ribbed edge 4, the tight material 5 and the sealing material 6 in the groove 1a'.
At the same time, the attachment is held by a tight material 5 and a seal material 6 at the end portion 2a'.

Reference numeral 7 denotes a backing interposed at the joint between the ends of the mullions 1 and the ends of the mullions 2, and is made of an elastic material molded from, for example, synthetic rubber or synthetic resin.

As shown in FIGS. 1 to 6, the backing 7 has a protrusion 7a that protrudes into the groove 1a' to attach the mullion main body 1a.
To install the blind main body 2a, the engaging portion 7b that protrudes into the groove 2a' is engaged with the protrusions 2a'', 2a'' for locking the blind cover 2b formed on the outer surface of the blind main body. and the outdoor surface 2a'' of the blind main body 2a (in this embodiment, the protrusion 2a'').

The surface 7 in contact with the outdoor surface 2a'' is defined as the surface between 2a''
C, the surface 7d that contacts the mullion main body 1a, and the blind cover 2
It has a surface 7e that comes into contact with the end portion of b.

Reference numeral 8 denotes an auxiliary backing disposed on the upper surface of the backing 7 and the blind cover 2b at the joint between the mullion 1 and the blind 2, and is made of the same material as the backing 7;
As shown in FIG. 7, a surface 8a is formed to adhere to the top surface of the blind cover 2b.

Next, to explain the assembly order of the structure of this invention, first, the engagement grooves 7f, 7f of the backing 7 are engaged with the protrusions 2a'', 2a'' of the non-Japanese body 2a, and the backing 7 is attached to the non-Japanese body. 2a, and after engaging the eyeless body 2a with a bracket (not shown) attached to the mullion 1, insert the backing as shown by arrow A in FIG. 7 is pushed between the outdoor surface of the non-Japanese body 2a and the mullion body 1a.

In this case, if a tapered portion 7a' is provided at the tip of the projection 7a, the backing 7 can be easily removed.

Next, the mullion auxiliary frame 1b constituting the mullion 1 is placed on the top of the backing 7 while engaging with the mullion main body 1a, and then the backing 7 7e attached to the left and right ends of the mullion main body 2a
, 7e, and then attach the auxiliary backing 8 to the top surface of the blind cover 2b to complete the process.

In the rain cover structure of this invention configured as above,
The surface 7C of the backing 7 is the outdoor surface 2a'' of the non-Japanese body 2a
At the same time, the surface 7d is crimped to the mullion main body 1a, and the surface 7e is crimped to the end of the mullion cover 2b. can prevent rainwater from entering the groove 1a', and the installation of the cover 2 from the end of the cover 2b to the groove 2a can prevent rainwater from entering the groove 1a'.
It can also prevent rainwater from entering the interior.

Further, since the open body is pressed toward the room by the surface 7C of the backing 7, the airtightness between the indoor surface of the open space 2 and the mullion 1 can be maintained completely.

Note that rainwater flows back from the drain hole/outside air inlet 9 formed by cutting out a part of the non-Japanese body 2a, and the installation is done in the groove 2a'.
Even if the wastewater from the space 10 enters the space 10 formed by the non-Japanese body 2a and the non-Japanese cover 2b, it will not flow into the mullion 1.

Furthermore, even if rainwater enters the groove 2a' for some reason, a regular weir plate (not shown) is attached to the end of the mullion 2. It never enters.

Although the above embodiment describes the case where the inside of the mullion 1 is composed of the mullion main body 1a and the mullion auxiliary frame 1b, the case where the mullion is formed of one member, that is, the case where the mullion auxiliary frame is not used is described. You can also do a rainy day in the same way.

This second embodiment, as shown in FIGS. 8 to 10,
An example will also be shown in which the auxiliary backing 8 is not used and the joint between the mullion 1 and the mullion 2 is closed from rain using only one backing 7.

Note that in FIGS. 8 to 10, other structures are the same as those in the first embodiment, so the same reference numerals are given and explanations thereof will be omitted.

As explained above, the rain protection structure of this invention uses a molded elastic backing made of synthetic rubber or synthetic resin to waterproof the joint between the mullion and the mullion. Even if there is some error in the position when installing the blind cover, the dimensional error can be absorbed by the backing, and there is an advantage in construction that the blind cover can be installed in a predetermined position. .

In addition, since a molded backing is used instead of using an amorphous sealing material at the joint between the mullion and the open space as in the past, there is less peeling due to heat expansion and contraction of the open space material, and less deterioration over time, resulting in long-term watertight performance. can be maintained.

In addition, the backing is tightly inserted between the mullion and the outdoor surface of the mullion main body, and the other side is provided in close contact with the end of the mullion cover, so that the joint between the mullion and the mullion is closed. It has an excellent effect of being able to effectively maintain the water-like properties of the water, and its utility value is remarkable.
