Description

Technical Field

[0001] This utility model relates to the field of building curtain wall technology, specifically to an exterior decorative curtain wall for building engineering. Background Technology

[0002] In the field of architectural engineering, exterior curtain walls, as an important component of building facades, not only serve the function of aesthetic decoration, but also need to meet requirements such as structural stability and convenient installation.

[0003] However, existing curtain wall systems still have many problems during installation: Among them, the existing curtain wall keel and building wall are mostly connected by fixed-size connectors, which have poor adaptability and are difficult to adjust flexibly according to the flatness of the wall or installation error on site, resulting in insufficient installation accuracy and affecting the overall structural stability. In addition, the assembly of existing keels mostly relies on complex processes such as on-site welding, which is not only time-consuming and labor-intensive, but also prone to damage to components due to improper operation, increasing construction costs. In addition, the existing curtain wall structure and keel are mostly fixed by bolt through-hole connection. During installation, the bolt holes need to be precisely aligned, and the bolts need to be completely unscrewed during disassembly, which brings great inconvenience to later maintenance and replacement. Therefore, there is an urgent need for an exterior decorative curtain wall structure that can improve installation convenience and enhance installation flexibility. Utility Model Content

[0004] The purpose of this utility model is to provide an exterior decorative curtain wall for building engineering to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an exterior decorative curtain wall for building construction, comprising a main keel, a first connector, and a second connector. The first connector is installed on the building wall. The main keel is installed on the second connector via the first connector. A transverse keel is installed on the main keel. A locking post is threaded onto the transverse keel. A screw nut is provided at the outer end of the locking post. A locking block is provided at the end of the screw nut near the locking post. A curtain wall body is provided on the outer side of the transverse keel. A third connector is provided on the inner side of the curtain wall body. An insertion groove is provided on the third connector to cooperate with the locking post. A locking groove is provided on the insertion groove to cooperate with the locking block.

[0006] The present invention is further configured such that a first connecting groove is provided on the first connecting member, and a triangular rotary-cut double-locking anchor is installed in the first connecting groove. The inner end of the triangular rotary-cut double-locking anchor is connected to the building wall, and the outer end passes through the first connecting groove and is threaded with a first nut. During installation, a hole is first drilled in the building wall for installing the triangular rotary-cut double-locking anchor. During installation, it is preferable to fill the drilled hole with anchoring adhesive or special chemical adhesive. The end of the triangular rotary-cut double-locking anchor that is cut into the concrete is screwed into the drilled hole and fixed. After that, the first connecting member is sleeved on the outer connecting section of the triangular rotary-cut double-locking anchor through the first connecting groove. Then, the first nut is tightened on the outside of the triangular rotary-cut double-locking anchor, thereby realizing the installation and fixation of the first connecting member on the building wall, so as to facilitate the installation of the main keel in subsequent steps.

[0007] The present invention is further configured such that the second connector has a slot, and the first connector has a insert strip, which slides into the slot.
