Novel special-shaped aluminum veneer curtain wall modular keel mounting process

Abstract

The invention discloses a novel special-shaped aluminum veneer curtain wall modular keel installation technology which comprises the steps that according to a curtain wall design drawing, secondary keels of all models are decomposed and grouped, and the secondary keels of all models subjected to decomposition and grouping are subjected to hot bending machining; manufacturing and processing a positioning lofting underframe; the modeling secondary keels are positioned and welded; the modeling secondary keels are assembled; the aluminum veneer is installed; the modeling secondary keels are positioned on the building wall surface; and the modeling secondary keels are hoisted and fixed. The technical problems that building wall positioning is difficult, errors are large, cost is high, the rework rate is high, efficiency is low, and potential safety hazards are caused by long-time high-altitude operation are solved.

Description

technical field [0001] The invention relates to an installation process, in particular to a new type of special-shaped aluminum veneer curtain wall modular keel installation process. Background technique [0002] The existing special-shaped aluminum veneer curtain wall keel installation method is to rely on the drawing grid to set out the size, and then use the theodolite, level, total station and other instruments to find the positioning points on the original building wall through the site axis and structural elevation line one by one. Mark for positioning, and then place the keel at each marked positioning point and fix it by welding; the existing method for installation has the following defects: [0003] 1) The requirements for on-site positioning accuracy are relatively high, and it is difficult to achieve according to the existing conditions; [0004] 2) There are many tools and instruments to be used, and the process is cumbersome and difficult to operate; [0005]...

AI Technical Summary

Problems solved by technology

[0003] 1) The positioning accuracy requirements on the site are relatively high, which is difficult to achieve based on existing conditions;

[0004] 2) There are many tools and instruments that need to be used, and the process is cumbersome and difficult to operate;

[0005] 3) The error is relatively large. There are errors in marking the positioning points according to the axis and elevation line on the site. If multiple such positioning points are marked, errors will accumulate, which will make the shape of the special-shaped keel prone to deviation, and then make it follow the size of the drawing in the later stage. The processed aluminum plate cannot be installed;

[0006] 4) It is relatively difficult to locate the positioning points beyond the scope of the building wall, and it is prone to large deviations;

[0007] 5) Construction costs such as labor costs, time costs, and machinery costs are too high;

[0008] 6) The rework rate is high and the efficiency is low. If the aluminum veneer cannot be installed later due to large errors, it is necessary to re-adjust the shape of the sub-keel or re-position and install it;

[0009] 7) Long-term high-altitude operations will bring greater construction safety risks;

[0011] 9) The aluminum veneer needs to be installed and adjusted on the wall according to the size of the keel, and the construction is difficult and the efficiency is low
