Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention provides a wall supporting member on a building body, and fixing members at four corners of a wall such as a glass panel, a metal panel or a stone plate, and the fixing members are fixed to the wall supporting member. By doing so, the present invention relates to a curtain wall in which a wall body is attached to a building frame.

[0002]

2. Description of the Related Art As a curtain wall in which a wall is attached to a building frame, for example, one disclosed in Japanese Patent Laid-Open No. 7-27042 is known. In this curtain wall, a wall body supporting member is provided on a building body, fixing members are provided at four corners of the wall body, and the fixing members are fixed to the wall body supporting member to attach the wall body to the building body.

[0003]

A wall body supporting member of such a curtain wall includes a base member fixed to a building body, and a screw member fixed to the base member with a bolt.
It is composed of an intermediate member screwed and attached to this screw member and a wall body fixing member which is I-shaped and has holes at four corners and which is screwed and attached to the intermediate member.

For this reason, in order to attach the conventional wall support member to the building frame, it is necessary to fix the base member, fix the screw member, mount the intermediate member, and mount the wall member. However, since the intermediate member and the wall body fixing member are mounted while rotating themselves, the mounting work is troublesome. In particular, since the wall fixing member is I-shaped and heavy, the work of rotating and screwing the heavy wall fixing member while supporting the heavy wall fixing member is troublesome and requires a large amount of labor.

Further, since the wall body fixing member is mounted by rotating it, it is difficult to install the wall body fixing member in the correct orientation, and the respective holes of the wall body fixing member are displaced, and the wall is fixed to the hole. When the wall member is attached by fixing the fixing member provided on the body, the attachment position of each wall member may shift and the wall member may not be attached correctly.

Specifically, since the fixing members provided at one corner of four wall members vertically and horizontally adjacent to each other are fixed to the wall fixing member, the four fixing members and the four holes are formed. Since it is necessary to align them, the wall cannot be attached correctly because the orientation of the wall fixing member cannot be set correctly as described above.

The base member, the screw member, and the intermediate member are located at the upper, lower, left, and right central portions of the wall body fixing member, and the wall members are attached by fixing the fixing members to the four corner holes of the wall body fixing member. Therefore, the weight of the wall body acts on the intermediate member, the screw member, and the base member, and the length from the building body fixing portion of the base member to the wall fixing member is long, and the intermediate portion member, the screw member, and the base member have a large downward direction. Moment acts. For this reason, they bend with a large downward moment, and the supporting strength of the wall becomes weak.

Therefore, an object of the present invention is to provide a curtain wall which can solve the above-mentioned problems.

[0009]

According to a first aspect of the present invention, a base member having a connecting portion protruding toward the outside of a room is attached to a building frame, and a base portion having a fitting concave portion opening to the inside of the building is provided. A wall fixing member composed of four arms provided in an in-plane direction from the base to the in-plane direction by fitting the fitting recess into the connecting portion of the base member, By connecting the connection part with a bolt with a wall support member,
The fixing members are fixed to the four corners of the wall body toward the inside, respectively, and the fixing members fixed to the corners where the four wall bodies gather are connected to the four arms of the wall body fixing member, respectively, to form the wall body. It is a curtain wall characterized by being attached to. In a second aspect based on the first aspect, a mounting member fixed to the building body and a vertically long connecting portion provided in the mounting portion serve as a base member, and a hole opened in the in-plane direction is formed in the connecting portion. And a bolt hole facing the out-of-plane direction is formed in the out-of-plane direction outdoor side vertical surface of the connecting portion, and an in-plane-direction hole opened in the fitting recess in the wall fixing member and the fitting thereof. A hole is formed in the out-of-plane direction opening on the bottom surface of the recess, and the in-plane dimension of the fitting recess is the same as the in-plane dimension of the connecting portion,
The wall body fixing member is positioned in the out-of-plane direction by screwing a bolt inserted through the out-of-plane direction hole into the bolt hole of the connecting portion and pressing the bottom surface of the fitting recess against the vertical outdoor surface of the connecting portion in the out-of-plane direction. A curtain wall in which the wall body fixing member is positioned in the in-plane direction by inserting a bolt into each of the in-plane holes and screwing a nut.

[0010]

[Operation] According to the first aspect of the present invention, the wall supporting member is formed by fitting the fitting recess of the wall fixing member into the connecting portion of the base member fixed to the building body and connecting the same with bolts. Thus, the wall body support member can be attached to the building body by the work of mounting the building body of the base member, the work of fitting the fitting recess of the wall body fixing member to the connecting portion, and the bolting work, and the wall body fixing member can be mounted. Since it can be temporarily supported by the base member, it is not necessary for an operator to hold the wall body fixing member at the time of bolting work, and a large amount of labor is unnecessary. Also, by fitting the fitting recess of the wall fixing member to the connecting portion of the base member, it can be positioned in the in-plane direction and the out-of-plane direction, so that the four arms can be easily set to the predetermined positions in the vertical and horizontal directions. You can Further, since the fitting recess of the base portion of the wall body fixing member is fitted to the connecting portion of the base member, and four arms are provided above and below the base portion in the in-plane direction, the building frame of the base member is formed. Even if a large downward moment is applied from the fixing portion to the wall body fixing member, the wall body does not bend, and the strength of supporting the wall body becomes strong. According to the second aspect of the invention, since the vertical surface in the out-of-plane direction outdoor side of the connecting portion surely contacts the bottom surface of the fitting recess of the wall fixing member, the positioning accuracy in the out-of-plane direction is improved and The vertical surface comes into contact with the fitting recess of the wall fixing member to improve the positioning accuracy in the in-plane direction.
