2. Description of the Related Art Conventionally, the fixing of a curtain wall connection portion is performed as follows.
There is known a so-called dry seal method in which a silicon rubber-based structural gasket is used to hold a glass plate by utilizing its elasticity and pressure, and to play a role of sealing. In the conventional dry seal method, a glass plate is fitted into a rectangular metal frame, and the glass plate is pressed inward from the outside by a gasket in which a foot is fitted into a fitting groove formed on the outside of the metal frame. By using the elasticity and the crimping force, the glass plate is held and plays a role of sealing.

[0003]

The gasket used in the conventional dry seal method has a substantially T-shaped cross section in which a foot portion is formed at the center of the rear surface of a horizontally long main portion.
The glass plate is pressed from the outside to the inside by the gasket whose feet are fitted into the fitting grooves formed on the outside of the rectangular metal frame, so the glass plate has elasticity and crimping force of the main part of the gasket. It is only sealed by However, since the gasket is made of foam or elastic material and has low mechanical accuracy, even if the foot is fitted in the fitting groove formed on the outside of the metal frame, the main part of the gasket connects the glass plate from the outside. It has been pointed out that the mechanical accuracy of pressing down inside is low, and that if the pressure difference between the outside air pressure and the inside of the building becomes large, rainwater permeates through the seal portion. The present invention has been developed in view of the circumstances to provide a dry sealing device for buildings that can easily and completely seal even if the mechanical accuracy of the gasket is low.

[0004]

The present invention employs the following technical means in order to solve the above problems and achieve the object.

[0005] In a configuration in which glazing for supporting the glass back surface is disposed at both side ends of the surface of the intermediate opening material at the opening of the building, and a support portion facing the glass edge back surface is formed at an intermediate portion between both glazings, A fitting groove is formed on the surface of the support portion through both side walls with locking projections long in the longitudinal direction, and the fitting groove has a pair of substantially L-shaped main and foot portions formed in the fitting groove. The gasket is fitted with its feet in contact with both side walls of the fitting groove, and between the opposing sides of the gasket, the feet of the pressing member having the feet perpendicular to the width center of the back surface of the main part. A dry sealing device for construction, wherein a part is inserted, a fixing bolt is screwed from the surface of the pressing member to the bottom of the fitting groove, and the gasket is pressed and sealed to the glass surface by the main part of the pressing member.

In the gasket, the main part and the foot part are crossed at right angles to form a substantially L-shape, and a locking projection is formed on the outer surface of the foot part. A dry sealing device for a building, wherein a ridge is formed in a direction opposite to a direction of a foot portion, and a tapered surface is formed on an inner surface of the ridge to obliquely intersect an upper surface of a main portion.

In the pressing member, a foot portion formed of a pair of groove side walls is formed at the center of the back surface width of the elongated plate-shaped main portion, and a groove portion is formed between the pressing portions, and a plurality of grooves are formed in the longitudinal direction of the plate-shaped main portion. Along with mounting a fixing bolt by opening a bolt hole so as to penetrate the groove between the pair of feet, at both ends of the width of the main part surface,
A dry sealing device for buildings with tapered outer side walls.

[0008]

The present invention configured as described above has the following functions. Conventionally, a configuration is adopted in which the glass is contained integrally with a gasket having a foot portion on the back surface of the main portion. Therefore, it is difficult to fit the foot of the gasket into the fitting groove on the front end surface of the support portion of the intermediate seamless material because the locking projections and the like protrude and cause a large resistance. is there. In the present application, since the gasket is separated into two as a pair and the foot of the pressing member is inserted between the two feet, the gasket feet are inserted into the fitting grooves, respectively. The two gasket feet can be fitted simply by moving outward, and the gasket feet do not come off by inserting the feet of the pressing member between the opposed gasket feet. By pressing the fixing bolt attached from the front side to the bottom of the fitting groove to press the main back surface of both gaskets against the glass surface, the glass back surface is pressed against the glazing and the glass is firmly fixed. Sealed.
