Abstract

The invention provides a telescopic seam connecting method for a transverse paving single-layer metal wall surface plate. The method comprises the following steps that a first transverse main purline and a seam aligning sub purline are provided, and the seam aligning sub purline is vertically fixed on the end part of the main purline; a first transverse paving wall surface plate and a second transverse paving wall surface plate are provided, sealing plugs are pasted in positions near the end parts of the back sides of the first transverse paving wall surface plate and the second transverse paving wall surface plate by sealing adhesive tapes; the end part of the first transverse paving wall surface plate and the sealing plugs are fixed with the seam aligning sub purline, one side is tightly propped, and in addition, a certain lap joint length is left; the end part of the second transverse paving wall surface plate and the sealing plugs are placed at the other side of the seam aligning sub purline; a second transverse main purline and a vertical wall surface sub purline are provided, and the vertical wall surface sub purlien are respectively fixed with the end part of the second transverse main purline and the second transverse paving wall surface plate; and seam aligning stripped collected edges are provided, and the buckling and tight propping with the seam aligning sub purline is carried out. The method provided by the invention has the characteristics of displacement resistance, external force resistance, corrosion resistance, seepage resistance and the like. In addition, the performance in aspects of installation cost saving, on-site construction efficiency improvement and the like exceeds that of the traditional lap joint mode, and the unique advantages are shown.

Description

technical field [0001] The invention relates to the technical field of building roof systems, in particular, the invention relates to a method for connecting expansion joints of horizontally laid single-layer metal wall panels. Background technique [0002] Various metal wall panels in daily life are often subject to deformation caused by wind and rain, thermal expansion and contraction, and the main structure of the building, and the expansion joint joints of the wall panels must be able to adapt to the deformation accordingly. In particular, the expansion joints also need to consider the influence of wind pressure, self-weight, earthquake, temperature, etc., and must have the ability to resist deformation to ensure the safety of the expansion joints. At the deformation joints of the horizontally laid wall panels in the prior art, the horizontally laid wall panels are usually directly fixed with the wall structure nails and the wall purlins, so that the normal stretching an...

AI Technical Summary

Problems solved by technology

At the deformation joints of the horizontally laid wall panels in the prior art, the horizontally laid wall panels are usually directly fixed with the wall structure nails and the wall purlins, so that the normal stretching and displacement between the horizontally laid wall panels cannot be performed, resulting in the steel plates at the joints of the wall panels Be torn and eventually leak, corrode

[0003] Therefore, in view of the defects such as poor deformation resistance and insufficient facade effect at the expansion joint joints of various horizontally laid single-layer metal wall panels in the prior art, a new one with stronger displacement capacity, higher strength and other defects is needed. The expansion joint overlapping method with stronger wind resistance and waterproof function overcomes the shortcomings of the existing technology that it cannot be stretched, is easy to corrode, reduces the wind resistance performance of the wall panel, and is easy to leak.
