Stone non-curtain hanging piece, non-curtain unit and keel-free non-curtain system

Abstract

The invention provides a stone non-curtain hanging piece, a non-curtain unit and a keel-free non-curtain system. The stone non-curtain hanging piece comprises a hanging piece body, a non-metal connector, a metal connector and a fastener. The hanging piece body is a T-shaped block composed of a first extruding aluminum alloy piece and a second extruding aluminum alloy piece, wherein the first extruding aluminum alloy piece and the second extruding aluminum alloy piece are fastened into a whole through screws. The front end face of the first extruding aluminum alloy piece and the front end face of the second extruding aluminum alloy piece are respectively provided with a claw, wherein the claws are symmetrically arranged in an inwards inclining mode. The hanging piece body, the non-metal connector and the metal connector are connected in sequence. The invention further discloses the non-curtain unit provided with the hanging piece, and the non-curtain system. Firstly, construction can be conducted on a stone non-curtain structure according to a keel-free hanging and pasting technology, namely, no keel is used; secondly, the stone non-curtain structure has the cold-bridge and hot-bridge isolation function, the opening collapsing phenomenon on the notch portion of stone is avoided when the stone non-curtain structure is used for a long time, and the overall service life of the stone non-curtain structure is prolonged.

Description

technical field [0001] The invention relates to the technical field of stone non-curtain walls, specifically a stone non-curtain wall pendant, a non-curtain wall unit and a keel-free non-curtain wall system. Background technique [0002] Stone curtain walls are generally installed by dry hanging. According to the stone installation structure, it can be divided into: back-bolt stone curtain wall (that is, stainless steel expansion bolts are used to anchor and connect stone without stress, and the installation is safe and reliable.), but ultra-thin stone cannot be used because ultra-thin stone cannot overcome expansion. The internal stress of the bolt (ultra-thin stone is generally 5mm~~12mm); the pallet-type stone curtain wall (that is, the aluminum alloy pallet supports the bracket on the lower side of the stone, refer to Chinese patent document 2012200127070); the long groove-type stone curtain wall (That is to say, the stone is slotted up and down and stuck on the long al...

AI Technical Summary

Problems solved by technology

[0005] 1. The keel needs to be installed. The keel is the main body of the load. In order to meet the design requirements of the load (including gravity load and wind load, etc.), galvanized square steel pipes are generally used, and the steel consumption is large and the cost is high.

[0006] 2. The construction process is complex, requiring a series of steps such as keel laying, insulation layer pasting, stone panels, and sealant application. The technical requirements for on-site construction workers are relatively high, and the technical levels of on-site construction personnel are different. factor, so the consistency of the decorative surface is poor

[0007] 3. Traditional keels, pendants and decorative panels are all good conductors of heat. In the external wall system, the thermal expansion and contraction of stone and pendants are more obvious, while the temperature of the wall does not change much. The position difference is relatively large, which causes the connection parts of the pendant in the dry hanging system, especially the connection part between the pendant and the stone panel, which is prone to problems such as deformation, falling off, and collapse of the grooved part of the stone, resulting in the failure of the pendant. The collapse of the grooved part of the stone is more likely to cause connection failure, which makes the later maintenance cost higher
