Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a structure for reinforcing the upright of a vertical curtain wall in which a panel is attached between a plurality of uprights attached to a building frame.

[0002]

2. Description of the Related Art As a cubic curtain wall, there is known one in which upper and lower parts of a plurality of cubics are respectively connected to a building frame, and a panel is attached between the adjacent cubics on the left and right sides thereof.

In the above-mentioned cubic curtain wall, when the panel body is exposed to wind, a force (positive pressure) for pushing the panel body to the indoor side and a force (negative pressure) for pulling the panel body to the outdoor side act. Since the positive pressure and the negative pressure are supported by the vertical, the vertical tries to bend in an arc shape toward the indoor side by the positive pressure, and tries to bend in an arc shape toward the outdoor side by the negative pressure.

For this reason, it is necessary to make the vertical cross-sectional shape large so that the vertical does not bend toward the outside of the room due to positive pressure and negative pressure. There is a limit to the size, and for example, if a cubic curtain wall is connected to form a stairwell over the first and third floors of the building, the distance between the vertical connection parts will be It may become too long to prevent vertical deflection.

In order to solve this problem, the actual Kaihei 4-1 is used.
As shown in Japanese Patent No. 37115, the upper and lower parts of a truss structure mounting member are respectively connected to the upper and lower floors of a building frame, and an upright is attached to the outdoor side of the attaching member, and the upright is reinforced by the attaching member. What has been done is proposed.

[0006]

As described above, if the upright is reinforced by the truss structure mounting members, a large deflection of the upright can be prevented, but the truss structure mounting members are respectively located on the indoor side of each upright. Therefore, a large number of truss structure mounting members can be seen when viewed from the inside of the room, resulting in a very bad appearance.

Therefore, it is an object of the present invention to provide a vertical reinforcing structure for a vertical curtain wall which can solve the above problems.

[0008]

DISCLOSURE OF THE INVENTION The present invention relates to a vertical curtain wall in which a lower part and an upper part of a large number of cubes are respectively connected to a building frame, and a panel body is attached between adjacent cubes on the left and right sides thereof. Vertical mounting members of the truss structure are respectively connected to the indoor sides of the two cubics located on both sides of the plurality of verticals, and the lower and upper parts of each vertical mounting are respectively connected to the building frame. Then, the lateral mounting members of the truss structure are connected across the intermediate portions in the longitudinal direction of the left and right vertical mounting members, and the lateral mounting members are respectively connected to the plurality of uprights. Characterized in that the tension member is connected across the portion and the side of the building body so that tension is applied to the tension member when the lateral mounting member tries to bend in an arc shape toward the indoor side and the outdoor side. Cubic curtain wall Is a definitive mullions reinforcing structure.

[0009]

[Operation] Since the two cubes are reinforced by vertical mounting members, they do not bend in an arc shape toward the inside and outside of the room due to positive pressure and negative pressure. The horizontal mounting member and the tension member prevent the vertical portion from bending inward toward the indoor side and the outdoor side. As a result, the curtain wall does not bend in an arc shape toward the indoor side and the outdoor side due to the positive pressure and the negative pressure even if the distance between the lower part of the cubic and the connection part to the upper building frame is long,
Only the two vertical mounting members, one horizontal mounting member, and the tension member can be seen from the room, which is a good appearance.

[0027]

Since the two cubes are reinforced by the vertical mounting members, they do not bend in an arc shape toward the indoor side and the outdoor side due to the positive pressure and the negative pressure. The horizontal mounting member and the tension member prevent the vertical bending of the vertical arc toward the indoor side and the outdoor side. Therefore, even if the distance between the lower and upper parts of the cubic to the building frame is long, the curtain wall does not bend in an arc shape toward the inside and outside due to positive pressure and negative pressure. Only the vertical mounting member, one horizontal mounting member, and the tension member can be seen, and the appearance is good.
