Description

A curtain wall decorative strip connection structure

technical field

The invention relates to the technical field of building curtain wall construction, in particular to a curtain wall decorative strip connection structure.

Background technique

The curtain wall is the outer wall enclosure of the building. It is not load-bearing and hangs up like a curtain, so it is also called "curtain wall". It is a light-weight wall with decorative effect commonly used in modern large-scale and high-rise buildings. Composed of panels and supporting structure systems, it can have a certain displacement capacity relative to the main structure or itself has a certain deformation capacity, and does not bear the role of the main structure. The building envelope structure or decorative structure (the external wall frame support system is also a curtain wall system kind of). Common glass curtain wall structure forms: hidden frame, semi-hidden frame, exposed frame, point type, full glass, etc.

When the existing curtain wall is decorated, the simple method is usually to paint a decorative paint finish or lay wallpaper on the wall. However, there are many problems in this existing method that cannot meet people's needs. Therefore, when decorating curtain walls, decorative strips are usually used to decorate the wall. The existing decorative strips are a kind of building exterior decoration components that can Effectively enriching the facade effect of the building usually also plays a certain role in shading the sun and rain. During the specific installation, the decorative strip is fixed to the wall through the keel or the fixed pendant laid on the wall to achieve the effect of decoration. During the specific installation, the grooves and protrusions on the decorative strip and the keel are matched with each other , combined with the use of a large number of bolts and screws to fix the decorative strip, the construction process is more cumbersome, the construction cost is higher and the installation efficiency is reduced.

Contents of the invention

The object of the present invention is to provide a curtain wall decorative strip connection structure, which has the advantages of simple construction process and improved installation efficiency.

Above-mentioned purpose of the present invention is achieved through the following technical solutions:

A curtain wall decorative strip connection structure, comprising a wall, an aluminum alloy column connected to the wall, and a decorative strip body connected to the aluminum alloy column, the decorative strip body is fixedly connected with an aluminum alloy pendant, and the aluminum alloy The pendant is arranged in a "U" shape, and the opposite surface of the "U"-shaped aluminum alloy pendant runs through and is threaded with a first bolt. The aluminum alloy column is fixedly connected with an aluminum alloy adapter, and the aluminum alloy The adapter is provided with a waist hole, and the aluminum alloy adapter is provided with an opening for the rod of the first bolt to penetrate into the waist hole, and the aluminum alloy adapter is provided with an opening for A fixing mechanism that prevents the shank of the first bolt from moving in the direction of the opening in the waist-shaped hole.

Implement the above technical solution, when it is necessary to fix the decorative strip body to the aluminum alloy column on the wall, install the aluminum alloy pendant on the decorative strip body, install the aluminum alloy adapter on the aluminum alloy column, and drive the aluminum alloy The stem of the first bolt on the pendant passes through the opening on the aluminum alloy adapter, so that the stem of the first bolt enters the bottom of the waist-shaped hole, thereby connecting the main body of the decorative strip to the aluminum alloy column. The installation of the aluminum alloy column is directly completed by connecting the method, which saves on-site construction time and procedures, and at the same time significantly improves the processing quality; the setting of the fixing mechanism can prevent the rod of the first bolt from moving toward the opening in the waist hole, thereby The separation between the first bolt and the aluminum alloy adapter is prevented, and the fixing effect between the aluminum alloy pendant and the aluminum alloy adapter is improved.

Further, the fixing mechanism includes a screw detachably connected to the aluminum alloy adapter, the length direction of the screw is perpendicular to the length direction of the waist-shaped hole, and both ends of the screw can be detachably connected with sleeves , the sleeve is provided with a fixing piece facing the stem of the first bolt, a spring in a compressed state is connected between the fixing piece and the sleeve, and the fixing piece resists the elastic force of the spring and the stem of the first bolt Abut.

To implement the above technical solution, when it is necessary to prevent the rod of the first bolt from moving in the direction of the opening in the waist-shaped hole, connect the screw to the aluminum alloy adapter, install the sleeves to the two ends of the screw respectively, and install them to the After specifying the position, fix the fixing part against the elastic force of the spring and fix the rod of the first bolt; rely on the elastic force of the spring to fix the rod of the first bolt to the waist-shaped hole to prevent the first bolt from detaching in the waist-shaped hole and improve The fixing effect of the aluminum alloy pendant and the aluminum alloy adapter is improved; the screw is detachably connected to the aluminum alloy adapter to facilitate the installation and removal of the screw; the sleeve is detachably connected to the screw to facilitate the sleeve. Installation and disassembly, combined with practical construction applications.

Further, the fixing member includes a semi-arc-shaped first locking cylinder fitted to the rod of the first bolt, and a second locking cylinder cooperating with the first locking cylinder is hinged on the first locking cylinder. The positions of the first locking barrel and the second locking barrel away from the hinge are locked by screws.

To implement the above technical solution, when it is necessary to make the fixing part complete the fixing of the first bolt, firstly, the first locking cylinder is brought into contact with the rod of the first bolt against the elastic force of the spring, and then the second locking cylinder is placed on the first locking cylinder The hinge point of the hinge is rotated to the state of fitting with the first locking cylinder, and the first locking cylinder and the second locking cylinder are locked by screws, so that the fixing part abuts the first bolt in the waist-shaped hole; by means of screw locking, To a certain extent, the screw can be prevented from moving along the direction of its axis, so that the fixing member can further improve the fixing effect on the first bolt.
