Description

Technical Field

[0001] The invention relates to the technical field of building decoration construction, and in particular to a free-form laminated ceramic tile roof supporting structure and a construction method thereof. Background Art

[0002] The main building of Jiaxing Nanhu Future Plaza adopts a large-span special-shaped spatial steel structure arch truss system with a white ceramic tile curved curtain wall roof, combined with green space on each floor, to form a staggered building complex.

[0003] Among them, the white ceramic tile curved curtain wall roof is a complex hyperbolic shape. The existing construction process is to use three-dimensional software to simulate the curved surface of the hyperbolic roof skin, and implement zoning construction. The supporting keels within each partition range are pre-bent in the factory, and the prefabricated supporting keels are transported to the site and installed in sequence according to the set position to achieve the fitting construction of the hyperbolic roof skin. However, the keel suitable for the prefabricated bending process has a small bending radius range, which is generally within ten radii, and the bending radius of different keels varies greatly. The white ceramic tile curved curtain wall roof has a large area and complex shape. The bending radius of the prefabricated keel is large and prone to rebound. The bending radius size reaches hundreds of types, which makes positioning and installation difficult. Moreover, in order to ensure a smooth hyperbolic exterior decoration effect, the radius difference between different prefabricated keels is small, which not only increases the processing difficulty of the prefabricated keel, but also makes it difficult to accurately control the installation position and installation accuracy of the prefabricated keel according to the structural design and structural deviation, resulting in the inability to realize the design of the curved curtain wall roof. Summary of the invention

[0004] In view of the problem that it is difficult to accurately control the installation position and installation accuracy of the prefabricated keel according to the structural design and structural deviation in the existing method of assembling the hyperbolic roof support structure on site by pre-bending the keel, the purpose of the present invention is to provide a free-form laminated ceramic tile roof support structure and a construction method thereof.

The construction method of the free-form laminated ceramic tile roof support structure according to claim 6, characterized in that: In step S2, the spacing between two adjacent purlin supports is determined according to the deflection of the positioning purlin, the load allowed to be applied during the cold bending construction of the positioning purlin is calculated, and whether the installation position and height of the additional purlin supports are reasonable is determined according to the profile deflection and the allowable load. If reasonable, the additional purlin supports are positioned according to the calculated data; if unreasonable, the spacing and installation position of the two adjacent purlin supports are adjusted until the calculation results meet the requirements of the profile deflection and the load.

8. The construction method of the free-form laminated ceramic tile roof support structure according to claim 6, characterized in that: In step S2, the purlin support includes a support rod, an outer sleeve and a base. The support rod is vertically arranged and fixedly connected to the top of the main steel structure of the building. The base is connected to one end of the outer sleeve. The other end of the outer sleeve is sleeved and connected to the support rod. After the support rod is fixed to the top of the main steel structure of the building, the relative distance between the outer sleeve and the support rod is adjusted so that the connecting line between the top ends of two adjacent purlin supports and the additional purlin support is consistent with the curvature of the ceramic tile installation positioning curve. After the relative position of the outer sleeve and the support rod is determined, the two are welded together or locked and fixed by through bolts.
