As the focal point of spatial vision, the construction accuracy of irregular cylindrical surfaces directly affects the realization of spatial aesthetic value. For the 15 meter ultra-high irregular seamless cylindrical metal column project, the unique curvature and vertical orientation pose strict requirements for measurement and positioning, skeleton leveling, and seamless splicing.

This article will focus on the five key processes from spatial layout to closure treatment, emphasizing how to transform fluid modeling in design drawings into a spatial device that combines structural safety and visual integrity through precise construction control.

Specific construction process: measurement and laying out → fixing skeleton connectors → fixing skeleton - installing panel - closing structure treatment.

1、Measurement and laying out:

Before starting any process, the site is cleaned and measured and laid out according to the "detailed drawings";

Firstly, the position of the skeleton needs to be projected onto the base layer. Only by laying out can the accuracy of skeleton construction be ensured. The skeleton is fixed on the main structure. Before laying out, the quality of the main structure should be checked. If there is a large error in the verticality and flatness of the main structure, it will inevitably affect the verticality and flatness of the skeleton. It is best to complete the wiring in one go. If there are any errors, they can be adjusted at any time.

2、 Fixed skeleton connectors

Expansion bolts can be installed on the walls of the main structure to achieve consistency between the connecting components and the main structure.

Due to the small size error, it is easy to ensure the accuracy of quality. The construction of connectors is mainly to ensure firmness and reliability. The length, height, and burial depth of expansion bolts of the weld seam should be strictly controlled. The surface of connectors such as steel sections should be galvanized, and anti rust paint should be applied to the welds to prevent corrosion over time.

3、Fixed skeleton

The skeleton should be pre treated with anti-corrosion measures. The installation position of the skeleton should be accurate, and the connection should be firm. After installation, check the centerline, surface elevation, etc. For multi story building exterior walls, in order to ensure the installation accuracy of the panels, it is advisable to use a theodolite to penetrate the crossbeam and vertical frame members. Deformation settlement joints, variable cross-sections, etc. should be properly treated to meet the requirements for use.

4、Wall metal plate installation

a、 The installation and fixation of metal plates should be both firm and reliable, as well as simple and easy to implement. Firmly first, safety issues should not occur under any circumstances. And it should be easy to operate. Only structures that are easy to operate are reasonable and can better ensure safety.

b、Now you know that there are many ways to fix metal plates, and in this case, "welding" is the main method. In addition, it is better to use "dry hanging" or "nailing" on the wall.

c、Because the case we are using is achieved through seamless connection through "welding", after the panel is completed, the metal sheet manufacturer needs to enter the site to produce the decorative paint and polish the weld seam.

△Metal plate welding

Although the shape of metal plates has taken into account waterproof performance during ordering and processing, if the material bends and the joints are uneven, the waterproof function of the shape may be lost, especially in the corners, which is particularly evident. Such as the closure of the top end of the horizontal part, the treatment of expansion joints and settlement joints, and the handover treatment of two different materials. These areas are often the focus of decorative construction, as they not only relate to aesthetic issues, but also have a significant impact on functional use.

△On site spraying of decorative paint to achieve seamless effect

Therefore, when carrying out node deepening, in addition to using the principle of closing the mouth as theoretical support, it is also necessary to combine the actual situation on site to carry out node deepening work; The main person in charge of this part of the work is the scope of work for the 'on-site deepening designer'.

5、Finished product protection

After the installation of metal panels, plastic film or other materials should be used to cover and protect areas that are prone to contamination. Safety railings and boards should be installed to protect areas that are easily scratched or touched.
