It sweeps the thick solid walls of traditional buildings and becomes a changeable and colorful wall image, and becomes the protagonist of modern building exterior wall modeling.
Installation of embedded parts embedded iron parts are the stress components of the curtain wall on the main body of the building.
To draw the wall partition drawing, the original designer usually draws the wall partition drawing according to the wall shape and structure of the building and the expected design effect, and then the curtain wall construction unit hires a qualified curtain wall design unit to deepen the design, issue detailed partition and construction drawings, and submit them to the original curtain wall designer for confirmation.
According to the thickness of the component with embedded parts, another kind of steel through wall pin (one end with wire and one end with welded steel plate) can be processed to fix the keel connecting plate.
At the same time, attention should be paid to the integrity and safety of the curtain wall to achieve the unity of function and beauty.
(5) Pouring caulking silica gel, pouring caulking silica gel is the finishing work after the dry hanging of materials, which can improve the aesthetics of curtain walls and prevent the deformation caused by the thermal expansion and cold contraction of dry hanging stones.

Generally, the drawings require the embedded parts to be embedded during the construction of the main structure.
Stone plate installation (1) the dry hanging parts should be selected with the quality meeting the standard, and the dry hanging parts with the shape of dovetail processed by galvanized flat steel can be selected.
If embedded in advance, disputes will occur during the handover of the working face due to problems such as accuracy, so post embedded parts are mostly used in actual construction.
In addition, the through wall pin shall be applied to the infilled wall to fix the connecting plate.
(3) For plate installation, the vertical decorative line is the key point of quality, especially the vertical line with a size less than 200.
The connection between embedded parts and main structure mainly includes expansion bolt, chemical anchor bolt and through wall pin.
The stone glue mixed with quick drying hardener is not easy to wipe, polluting the board surface and affecting the quality.
The length (height) of the vertical line is mostly the same as the height of the front panel, and the height of the front panel is mostly more than 600.
However, if the embedded parts are not fixed firmly in advance, they may shift during concrete vibration, or the embedded parts may not be used due to changes in curtain wall construction, or the installation accuracy is low and cannot meet the use requirements.
The quality of the installation of embedded iron parts directly affects the structural safety of the curtain wall, and the accuracy of installation directly affects the accuracy and appearance quality of the curtain wall.
Moreover, the construction unit of the main structure of the building and the curtain wall construction unit are probably not the same group of people.
The installation of metal framework should be carried out in strict accordance with the specifications, and attention should be paid to the importance of knocking off welding slag and painting antirust paint after the welding of main and auxiliary keels.
According to the actual situation of the construction site, this paper mainly discusses several precautions in the construction of the stone curtain wall for reference only.
Building curtain walls mainly include glass curtain walls, aluminum-plastic panel curtain walls, stainless steel curtain walls, stone curtain walls and other types.

Curtain walls can build rich exterior wall effects on buildings and realize peculiar architectural art modeling.
Among them, stone curtain wall is a major category of architectural curtain wall, which is widely used in many high-end, ancient and simple new projects and renovation projects.

(4) The technical specifications for fire belts and stone curtain walls require that fire belts and fire zones should be set up, but the reality is that some curtain wall drawings do not design fire belts, or they are designed but not done during construction.
The vertical line shall not be connected with glue, and each vertical line panel shall be slotted and connected with connectors; When scraping the stone glue on the board, do not scrape the glue on the front of the stone board.
4.
(2) The main defects of stone slotting are that the slot joint is too wide, open, and the distance between the two short slot edges and the two ends of the stone slab does not meet the requirements of the specification.
The fire belts can isolate the fire source and prevent the spread of fire, so they should be set up and constructed according to the specifications.
For places where the structural thickness is less than or equal to the length of the design expansion bolt or anchor bolt (such as cornice breast board, etc.), do not reluctantly use expansion bolts or chemical anchor bolts during construction.
T-shaped hanging parts are strictly prohibited to ensure the independence and safety of dry hanging stones.
Dry hanging stone curtain wall is a new process used after the 1990s.
Construction process flow: draw the partition diagram of the wall → plate cutting, processing, and applying water repellent → snap the line of the partition of the wall → install the embedded parts → install the metal framework → install the stone plate → check the installation quality → pour the caulking silica gel → clean the surface of the curtain wall.
During construction, the line should be drawn on the slab and the slot should be slotted according to the requirements of the specification, and the slot position and slot width should be mastered.
Although the stone curtain wall has good integrity and durability, there are still some imperfect and unsafe factors in the construction of the stone curtain wall.
In short, the construction of stone curtain wall ensures the design facade effect.
2.
Technical disclosure should be done during construction to popularize antirust paint to workers.
It also overcomes the disadvantages of wet operation method, such as blooming, freezing, tears, corrosion, falling off, construction pollution and so on.
Its process is simplified, the construction is not limited by seasons, and the pollution is less.
The stone joints should be embedded with plastic strips, the joint glue should be poured uniformly, the connection is not obvious, the internal and external corners should be constructed in place, and there should be no falling joints, broken joints and other phenomena.
