Metal roof deformation joint connection structure and installation method therefor

Abstract

The invention discloses a metal roof deformation joint connection structure and an installation method therefor. Deformation joint edge sealing purlines perpendicularly and fixedly connected with steel structure main purlines are arranged on two sides of a roof structure deformation joint; a roof deformation joint cover plate is paved on the top surface of the roof structure deformation joint; standing seam deformation joint end part support seats are fixedly arranged on the top surfaces of the deformation joint edge sealing purlines; anti-condensation heat-resistant rubber cushions are arranged at intervals; the end part support seats arranged in parallel are used for connecting standing seam metal roof boards and a roof deformation joint cover plate by lock edges; EPDM (Ethylene-Propylene-Diene Monomer) rubber strips with rubber strip holes are arranged at the lower part of the roof deformation joint cover plate between the deformation joint end part support seats; and butyl structure adhesive tapes are arranged between the top surfaces of the EPDM rubber strips and the roof deformation joint cover plate. According to the structure and the method, the problems of easiness for water seepage, poor heat insulation and energy conservation performances and poor building airtightness of a conventional standing seam metal roof deformation joint can be effectively solved; and meanwhile, through accessory and assembly type structure and device, the construction is simplified, so that the construction accuracy and reliability of workers are higher.

Description

technical field [0001] The invention relates to building technology, in particular to a metal roof deformation joint connection structure and installation method. Background technique [0002] The current development direction of my country's construction industry is to vigorously promote prefabricated buildings. The steel structure prefabricated building is fully in line with the country's construction industry orientation. Its system has the advantages of light structure weight, good seismic performance, and short construction period. It is widely used in industrial and civil buildings in my country. At present, in civil public buildings, steel structure standing seam metal roof systems are usually used because of the requirements for roof modeling effects and large structural spans. [0003] However, many years of design and construction practice have found that the steel structure standing seam metal roof system is very weak in the treatment of structural deformation jo...
