During construction, the laminated steel truss 2 is welded and assembled on site and is mounted on the main cantilever steel beam in a hoisting mode. The upper end and the lower end are connected by adopting a hinge joint. In order to avoid the situation that the displacement of the lower cantilever beam 1 is larger and the gap is larger when the upper cantilever beam 1 is installed due to the fact that the lower cantilever beam 1 is taken as a fulcrum in the installation process of the laminated steel truss 2, the upper node is preferentially connected. Meanwhile, in order to reduce deformation of the cantilever beam 1 caused by load of the ceramic plates 3, the installation sequence of the ceramic plates 3 is required to be optimized, the ceramic plates 3 with laminated steel frameworks are preferentially installed, and after the cantilever beam 1 is settled and stabilized, the ceramic plates 3 of the cantilever beam 1 are installed.
The ceramic plate 3 is installed and constructed in the following steps:
a) Embedding part is embedded
b) And (3) measuring and paying off: checking the structure size of the site, adjusting the grid of the keels, and marking horizontal and vertical control lines of keel installation on the installation wall surface by using a leveling instrument and a theodolite according to the structural separation of the curtain wall.

f) And (3) installing a water guide plate: a large-area curtain wall in an open system is provided with a water guide plate at every other two floors. And a water guide plate is arranged above each window opening. All the water guide plates were inspected to ensure continued and complete.
g) And (3) mounting a unit ceramic plate: the hanging pieces are inserted into the clamping grooves of the ceramic plates 3 from two sides to form a mounting unit and then hung on the cross beam, and the horizontal construction errors of the ceramic plates 3 are adjusted through adjusting bolts.
h) Ceramic plate 3 and parting adhesive tape are installed: the ceramic plate 3 is installed from bottom to top, and the parting adhesive tape is installed on the upright post from bottom to top at the same time, so that the continuous and complete installation of the whole curtain wall is ensured.
Alternatively, the present utility model can be designed in different shapes to meet the requirements of wing parts and structural performance of the building, and as shown in fig. 7-8, streamline shapes are adopted in the embodiment.
The ceramic plate 3 is a building board which is prepared by taking natural clay as a main raw material, performing high-pressure forming, low-temperature drying and high-temperature firing, and has the characteristics of green and environment-friendly property, pure texture, firmness, durability, fire resistance, flame retardance and the like, but has strict requirements on construction precision and deformation of a base material.
According to the requirements of section 7.3.8 of the technical Specification of metal and stone curtain wall engineering, the installation interval error of two adjacent vertical and horizontal plates is less than or equal to 2mm, the perpendicularity of a vertical joint and a wall surface is less than or equal to 10mm (the height of the curtain wall of the research object of the utility model is less than or equal to 30 m), the flatness of the curtain wall is less than or equal to 2.5mm, the size of a single ceramic plate 3 is 1200x600x20mm, and the installation alignment difficulty is high, so the requirements of the dry hanging ceramic plate 3 on the flatness and the perpendicularity of the curtain wall of the ceramic plate 3 are higher.
In particular, when the ceramic plate 3 with a large weight is a single plate, for example, 25.2kg, the unit area weight is about 35kg, which is far larger than that of an aluminum plate curtain wall or a GRC curtain wall. The ceramic plate 3 is made of brittle material and is easy to break when being subjected to plane external force, so that the requirements on the bearing capacity and deformation of the base material are high.
The utility model uses the square steel pipe concrete column 52, the reinforced concrete shear wall, the large cantilever steel beam and the laminated steel frame to participate in energy dissipation and shock absorption together, thereby reducing the structural deformation. The problem that the ceramic plate 3 is easy to break under the action of plane external force is solved by controlling the deformation of the main body structure and the curtain wall skeleton.
The ceramic plate 3 is sensitive to deformation of the body. Meanwhile, the ceramic plate 3 has great weight, the problem of large deflection of the large cantilever beam end is aggravated, the whole cantilever structure is obviously deformed, and the ceramic plate 3 is easy to crack and drop.
According to the technical scheme, the deformation of the main body structure, the overhanging steel beam and the laminated steel truss 2 is reduced, so that the ceramic plate 3 is kept intact under the action of external force.
The utility model solves the problems that the deformation of a complex-shaped structure (Y-shaped structure) and the auxiliary structure thereof is overlarge under the action of external force, thereby influencing the deformation of the curtain wall structure. The ceramic plate 3 curtain wall engineering is used as a peripheral protection structure of a main body structure, and not only meets the bearing capacity and deflection checking calculation, but also meets the effects of shock resistance, wind resistance and temperature.
