Connection node structure of fair-faced concrete prefabrication exterior wall hanging plates

Abstract

The invention discloses a connection node structure of fair-faced concrete prefabrication exterior wall hanging plates. The connection node structure comprises first connection angle iron, second connection angle iron and a support bolt; the first connection angle iron is fixed with an embedded base in a main body frame structure in a welding mode, the first connection angle iron and the second connection angle iron are each provided with a long-strip-shaped through hole, the support bolt is arranged on the first connection angle iron and used for supporting a lower bracket of the upper exterior wall hanging plates located above the support bolt, the first connection angle iron is fixedly connected with the second connection angle iron through a first connecting bolt, and the horizontal edge of the second connection angle iron is fixed with an embedded nut located in an upper bracket of the lower exterior wall hanging plate located below the second connection angle iron through a second connecting bolt. According to the connection node structure of the fair-faced concrete prefabrication exterior wall hanging plates, connection is convenient, and a certain displacement can be generated in the up and down direction and the left and right direction to prevent the exterior wall hanging plates from being damaged and disengaged when the connection node structure bears too large loads.

Description

technical field [0001] The invention relates to the field of fixing devices for building coverings, in particular to a connection node structure of fair-faced concrete prefabricated exterior wall hanging panels. Background technique [0002] For a long time, architectural engineering design has pursued the principles of practicality, safety, economy, and beauty. With the development of the national economy, architecture, a special work, has become a carrier that reflects the social and economic level and cultural concepts of an era. Fair-faced concrete exterior wall hanging panels, with their unique decorative effects, have won the love and recognition of the public and are widely used in the field of public buildings. The fair-faced concrete hanging slab has very strict requirements on the installation and connection structure. The ideal connection structure requires easy connection, easy adjustment and positioning, firm connection, and can produce a certain displacement wh...

Problems solved by technology

The fair-faced concrete hanging slab has very strict requirements on the installation and connection structure. The ideal connection structure requires easy connection, easy adjustment and positioning, firm connection, and can produce a certain displacement when bearing excessive loads to prevent damage and fall off. There is no such thing at present. perfect connection structure

[0003] The external wall hanging panel connection structures disclosed in Chinese patent documents CN101922242A, CN202850287U, and CN102644339A cannot be adjusted up, down, left, and right. The connection structures are all rigid connections. When encountering rare loads such as earthquakes, large internal forces will be generated in the hanging panels, resulting in cracks or even failure and falling off, resulting in major accidents.
