Light steel structure passive type low-energy-consumption energy-saving roof system and dry construction method

Abstract

The invention provides a light steel structure passive type low-energy-consumption energy-saving roof system and a dry construction method. The construction method of the roof system comprises the steps of laying an oriented structural board (OSB) on a galvanized steel roof truss; laying a first waterproof roll on the oriented structural board (OSB); mounting counter batten supports on the first waterproof roll at an equal interval, and laying a second waterproof roll on the top faces of the counter batten supports; embedding second insulation boards between the first waterproof roll and the second waterproof roll at an equal interval; mounting counter batten between the second insulation boards and the second waterproof roll; fixing multiple roof battens on the second waterproof roll at an equal interval; overlapping multiple roof tiles at the top of each roof batten in a staggered mode. The light steel structure passive type low-energy-consumption energy-saving roof system and the dry construction method have the advantages that on the basis that building expense is not increased and even decreased, the excellent energy-saving and heat preservation effect is achieved through deep processing of the building structure, the construction process is simple, safety and high efficiency are achieved, no pollution is caused, and the system is a safe, firm and livable building which can achieve housing industrialization.

Description

technical field [0001] The invention belongs to the technical field of building structures, and in particular relates to a light-weight steel structure passive low-energy and energy-saving roof system and a dry construction method. Background technique [0002] The traditional roofing system is a cement mortar structure, which mainly has the following disadvantages: [0003] (1) During the construction of the cement mortar structure, there are many problems such as complex construction technology, slow construction speed, low construction efficiency and environmental pollution during the construction process. [0004] (2) The ventilation and heat insulation performance of the roof system of the cement mortar structure is low, which is not conducive to energy saving. [0005] (3) The roof system with cement mortar structure has poor safety performance of wet-laid tiles, and it is easy to fall off due to thermal expansion and contraction. Therefore, it has the disadvantages o...
