Abstract

PURPOSE:To improve integral feeling with a face material of an edge frame material holding the end section of the face material. CONSTITUTION:In a curtain wall, in which either one or both of the upper and lower end sections and left and right end sections of a face material are engaged and held to approximately U-shaped cross sectional edge frame members 21, 22 protruding to a face material supporter in response to either one or both of said end sections on the outdoor side face of the face material supporter formed onto the external surface of a building, the side end faces of end sections held to the edge frame members 21, 22 of the face material are formed in inclined faces 23, 24 inclined near the center of the face material in the outdoor direction. The slipping-off of the end sections of the face material is prevented under the state, in which the U shaped outdoor side plates of the edge frame members 21, 22 are formed in the same surfaces as the outdoor plate surfaces of the face material and the edge frame members 21, 22 are abutted against the inclined side end faces of the face material.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a surface of a curtain wall for holding the face material in a non-slip state by engaging one or both of the upper and lower end portions and the left and right end portions of the face material with the edge frame member. TECHNICAL FIELD The present invention relates to an edge frame type detent holding structure for materials.

[0002]

2. Description of the Related Art Conventionally, a large number of adhering frame material adhesive glasses, which are formed by adhering an engaging frame material to the inner surface of a glass quadrant, are attached to a face material support on the outer surface of a building by the engaging frame material so as to be adjacent to each other. ,
We proposed an SSG curtain wall with a beautiful appearance that gives the impression of a single piece of glass by leaving only a small joint between each adjacent glass, but the glass comes off when the adhesive of the locking frame adhesive glass deteriorates. As a safety measure to prevent this, the horizontal members are extended from the above-mentioned surface material support between the adjacent parts of each glass above and below, and the cross-section co An edge frame type retainer holding structure has been proposed in which upper and lower ends of glass are fitted and retained in a character-shaped retainer edge frame.

[0003]

However, in the above-mentioned conventional edge frame type slip-preventing and retaining structure, the edge frame rises from the glass surface to the outside of the room, thereby hindering the sense of unity with the glass.
In the SG type curtain wall, each glass is clearly divided into upper and lower parts, resulting in a significant loss of the impression of a piece of glass.

An object of the present invention is to provide an edge frame type retainer holding structure for a face material, which enhances the feeling of unity of the edge frame member with the face material and has an aesthetic appearance as if the edge frame member was removed.

[0005]

As a means for solving the above problems, the present invention is directed to either the upper and lower end portions or the left and right end portions of a face material on the outdoor side surface of a face material support formed on the outer surface of a building. In a curtain wall, one or both of which is engaged with and held by an edge frame member having a substantially U-shaped cross section which is provided so as to project on the face material support correspondingly, an end of the face material held by the edge frame member. The side end surface of the portion is formed into an inclined surface that is inclined toward the center of the surface material in the outdoor direction, and the edge frame member forms the U-shaped outdoor gutter side plate on the same surface as the outdoor gutter plate surface of the surface material. We propose an edge frame type retainer holding structure for a face material in a curtain wall, which prevents the end portion of the face material from coming off while being brought into contact with the inclined end surface of the face material.

The above "face material" in the present invention includes various materials such as glass, stone, concrete, ceramics, wood, metal, synthetic resin and composite materials thereof.

Further, according to the present invention, a face material fitting groove portion (that is, an edge frame member) provided in a face material support body which is formed of a normal cubic shape and a normal eye is fitted and held with four peripheral edge portions of the face material, A face material unit in which the face material is preliminarily framed by the left and right edge frame members is attached to the face material support, and the upper and lower end portions of the face material and the locking frame on one or both indoor side surfaces of the side material Locking frame material made by adhering materials The surface material is obtained by locking the bonded surface material to the surface material support and holding the upper and lower ends or the left and right ends of the surface material by the edge frame member, and other various curtain wall surfaces. It is applied to the edge frame type holding structure of the material. Embodiments of the present invention will be described below with reference to the drawings.

7), (28), (27a), and (28a) are inclined side end faces (23) and (2) of the glasses (19) and (19a).
4), (23a) and (24a) are brought into contact with each other to prevent the glass from coming off and to make the glass flush with the outdoor side plate surface to strengthen the sense of unity with the glass.

In each of the above examples, the glass (1
9) and (19a) are fitted in such a manner that the lower end of the glass is held by the lower rim frame material, and then the upper end of the glass is held by the rim frame material, and then the adhesive (20). 20
a) ... It can be performed by filling the outer frame side plates (27), (28), (27a), (28) of each edge frame member.
It is possible to reduce the vertical width of a), thereby further enhancing the feeling of unity with the glass, and obtaining the impression of a one-piece construction with another adjacent glass surface member.

[0014]

According to the edge frame type anti-slip holding structure for a face material in the curtain wall of the present invention, the face material can be held in the anti-slip state by the edge frame member, and the edge frame member is used as the face material. By placing the edge frame member on the same surface as the outdoor side plate surface, the sense of unity with the face material of the edge frame member can be enhanced, and a simple aesthetic appearance as if the edge frame member was removed can be achieved.
