Unit extensible type assembled metal gutter and manufacturing and installing method thereof

Abstract

The invention provides a unit extensible type assembled metal gutter which comprises a plurality of gutter unit sections. Each gutter unit section comprises a metal plate manufactured U-shaped gutter groove body section and a metal framework, the metal frameworks are fixedly arranged at the bottoms of the U-shaped gutter groove body sections and / or the side walls of the outer sides of the U-shaped gutter groove body sections and provided with connection structures connected with a building. Ports at two ends of each U-shaped gutter groove body section are integrally provided with a transverse U-shaped groove extensible interface portion, the outer sides of U-shaped groove extensible structure portions arranged at two ends of a U-shaped gutter groove body are provided with matched fastener structures, and adjacent gutter unit sections are integrally connected through the fastener structures. The invention further provides a manufacturing and installing method of the unit extensible type assembled metal gutter. By means of the unit extensible type assembled metal gutter and the manufacturing and installing method, assembling type construction can be achieved, the work efficiency is high, the quality is good, the construction is convenient, no welding is needed in a field, safety risks are small, the comprehensive cost is saved by 30%, the construction, installation, production and processing work efficiency is improved by three times, and the gutter maintenance cost is reduced by 80%.

Description

technical field [0001] The invention relates to drainage gutters for building roofs and building curtain walls, and provides a unit telescopic assembled metal gutter. The invention also provides a method for manufacturing and installing the telescopic assembled metal gutter of the unit. Background technique [0002] In the prior art, the drainage metal gutters on building roofs or building curtain walls are constructed and installed in bulk by processing the ditch body sections of the gutter in the factory, and then connecting the gutter body sections on site. There are generally four types of connection methods for drainage gutters: [0003] ①Lap joint: The upper ditch is pressed to overlap the lower ditch, and the length of the overlap is 50-50mm. [0004] ② Riveting: The upper ditch is pressed to the lower ditch and then rivets are added for anchoring. The riveting length is 30-80mm. [0005] ③Buckle connection: The folded edge of the upper gutter is buckled to press t...

AI Technical Summary

Problems solved by technology

[0010] ① On-site construction and installation of gutters in bulk, keel and gutter installation assembly, riveting or welding workload is heavy, work efficiency is low, and quality is difficult to guarantee

[0011] ② Gutter welding or seam glueing, manual inspection and cleaning of sand and soil, the gutter welding and glue joints are easy to crack and damage, and the waterproof and drainage performance cannot be guaranteed

[0012] ③The existing gutter expansion joints are divided into sections and the cost is high, the construction is difficult, and the overlapping joints are prone to water leakage

Gutter welding, fastening, and riveting cannot guarantee the expansion and deformation requirements

[0013] ④Existing gutter technology cannot implement standardized design, factory processing, on-site installation and assembly, and non-welding construction. The processing and installation efficiency is low, the quality is poor, the cost is high, and the construction is difficult
