Construction process for aluminum sheet roof upright standing seam system

Abstract

The present invention belongs to the technical fields of building engineering design and construction, and particularly discloses a construction process for an aluminum sheet roof upright standing seam system. The construction process for an aluminum sheet roof upright standing seam system comprises the process steps of installing built-in fittings, pouring concrete, installing purlin supporting plates, installing purlins, installing steel bottom sheets, installing non-woven fabric, installing a supporting seat, carrying out construction of aluminum panels, installing side flashings, installing cornices and aluminum sheets, and the like. The construction process for an aluminum sheet roof upright standing seam system has the following advantages: the degrees of freedom of roof sheets in the sheet length direction is not limited by fixed seats, and therefore, when temperature changes, the roof sheets are able to freely slide to stretch out and draw back on the fixed seats with no temperature stress generated; thus, the temperature deformation problem which is difficult to overcome for other sheet types is effectively solved, and the reliability of various properties of the roof sheets is guaranteed.

Description

technical field [0001] The invention belongs to the technical field of architectural engineering design and construction, and in particular relates to a construction process of an aluminum plate roof standing seam system. Background technique [0002] With the diversification of architectural design, some public buildings are pursuing the effect of facades, and at the same time, in order to meet the requirements of large indoor spaces of public buildings, they often use a combination system of long-span steel structures and metal roofs in the roof system. The aluminum plate roof standing seam system integrates waterproof, circulating ventilation, heat insulation and beauty, and is widely used. However, the existing construction methods generally have complex procedures and low efficiency, and the structural settings at the joints of the aluminum veneer and the facade wall and other structures cannot meet the requirements, and water leakage is prone to occur. The surface tem...

AI Technical Summary

Problems solved by technology

However, the existing construction methods generally have complicated procedures and low efficiency, and the structural settings at the joints of the aluminum veneer and the facade wall and other structures cannot meet the requirements, and water leakage is prone to occur.

The surface temperature of the metal roof can reach 60 degrees Celsius in summer, and the thermal expansion rate of ordinary aluminum is 1 / 1000. The ordinary aluminum roof construction method cannot expand and contract in the predetermined direction when it expands with heat and contracts with cold.

Therefore, when the temperature changes, the roof panel cannot freely slide and expand on the fixed seat, which will cause temperature stress, and there is a problem of temperature deformation that is difficult to overcome, and the reliability of various performances of the roof panel cannot be guaranteed.
