Building exterior wall double-layer heat insulation ventilation cuticle structure

Abstract

The invention relates to a building exterior wall double-layer heat insulation ventilation cuticle structure. The structure comprises an exocuticle and an endocuticle which is fixedly connected with an outer wall. A predetermined distance is reserved between the exocuticle and the endocuticle, a plurality of wood joists are fixedly connected between the exocuticle and the endocuticle, the wood joists are connected with the exocuticle through L-shaped connecting pieces, and the exocuticle comprises a plurality of green woods arranged in parallel at intervals. According to the invention, the exocuticle and the endocuticle are mutually spaced to form intervals, interlayer ventilation between the cuticles can be promoted, at the same time, the exotucicle can shield most of vertical incident solar rays to a certain degree, the surface temperature of the endocuticle is reduced, heat penetrating into a room is reduced, and the refrigeration load of an air conditioner in summer is reduced.

Description

technical field [0001] The invention belongs to the field of building exterior wall engineering, in particular to a double-layer heat-insulating and ventilating skin structure of a building exterior wall. Background technique [0002] In modern society, buildings have gradually become one of the huge carriers of resource and energy consumption. With the prosperity and development of economy and technology, the advancement of technical means has gradually weakened the consideration of natural environment and climate characteristics in architectural design. Modern buildings use too many artificial means to obtain a comfortable indoor environment, and seldom make full use of limited natural resource conditions like traditional buildings use passive design methods. According to statistics from the Energy Research Institute of the National Reform and Development Commission, the energy consumption related to buildings in cities and towns in my country is as high as 40%. At the s...

Problems solved by technology

The ecological wood exterior wall decorative strips include a strip-shaped board body, a rectangular cavity is arranged inside the board body, and at least one reinforcing rib with a structure integrated with the board body is provided inside the cavity, and the reinforcing rib and the board body are integrated. The vertical cavity sides of the cavity are parallel, the length of the vertical cavity sides of the cavity cannot adapt to seasonal changes, the heat dissipation and ventilation effect is not good in summer, the thermal insulation function is poor in winter, the material processing technology is complicated, the production cost is high, and the decorative effect is poor
