System for testing comprehensive performance of metal roof

Abstract

The invention discloses a system for testing comprehensive performance of a metal roof. The system comprises an upper tank body (1), a lower tank body (2), a sealing piece (18), a support (21), a first air supply/exhaust device, a pump (6), a shower pipe (60), a shower nozzle (61), a refrigerator (7), a refrigerating pipe (71), an electric control device (9), a hanging rod (11), a displacement sensor (12), an electric heater (13), a net rack (14), a temperature/humidity sensor (15), and a wind pressure sensor (91), wherein a closed space is formed by the upper tank body (1) and a metal roof testing piece (8); a closed space is formed by the lower tank body (2) and the metal roof testing piece (8); the first air supply/exhaust device comprises a first fan (3) and a reversing valve (5); a reversing device is arranged in the valve body of the reversing valve (5); when the reversing device is in a first reversing state, the first fan (3) exhausts air from the upper tank body (1); and when the reversing device is in a second reversing state, the first fan (3) supplies air to the upper tank body. The system for testing the comprehensive performance of the metal roof can be widely applied to the field of test of metal roofs.

Description

technical field [0001] The invention relates to a metal roof comprehensive performance testing system. Background technique [0002] With the development of science and technology, various modern buildings are displayed in front of people, such as glass walls, metal packaging and so on. At present, many new buildings adopt metal structure roofing systems, especially steel structure buildings, and their roofing systems naturally also adopt metal structure roofing systems. Composite metal roofing systems are more and more widely used in various industries, sports, entertainment, exhibition halls, retail supermarkets and other buildings. At present, the existing metal roof system of this kind of buildings usually adopts metal roof panels with internal support and fixing structures to obtain beautiful and stable use requirements; by setting various internal support fixings and various fasteners, it can also obtain There is a flexible placement space between the roof panel and ...

AI Technical Summary

Problems solved by technology

At present, there are limited detection methods for roof systems including metal roofs. The domestic detection of building roof systems is basically based on empirical visual inspection, which requires the accumulation of staff experience, such as detection of water leakage indicators, by directly opening the waterproof It is easy to damage the original building, and the above method is not accurate

In addition, there are methods for instrumental testing of the roof system, but the current testing is mainly aimed at testing one or two performance indicators (such as air tightness, water tightness, wind resistance, etc.) of the metal roof, and it is impossible to use a device and system to test Comprehensive detection of various properties of the metal roof, the entire detection cycle is long and the efficiency is not high
