Heat preservation ventilating rebuilding method of low-floor building external wall and roof

Abstract

The invention provides a heat preservation ventilating rebuilding method of low-floor building external walls and roofs, belonging to the technical field of constructional engineering, wherein the solar energy is absorbed by orderly building an insulation board, a color sheet steel shingle, an outer window-shade, a roof sheathing and a rising ridge; in winter, the hot air can be absorbed; in summer, the hot air can be exhaled; and in spring and autumn, an air insulation layer is formed. According to the method in the invention, the existing building rebuilding can meet the comprehensive demands of heat insulation, heat preservation, energy conservation, ventilating, reasonable cost, and low carbon building.

Description

technical field [0001] The invention relates to a method in the technical field of construction engineering, in particular to a method for thermal insulation and ventilation renovation of exterior walls and roofs of low-rise buildings. Background technique [0002] Existing traditional low-rise building exterior walls are mostly brick blocks, which have disadvantages such as poor thermal insulation performance, no thermal insulation and energy-saving design, and inability to deliver fresh air to the room. [0003] In response to the above-mentioned problems in traditional low-rise buildings, many countries have studied a variety of energy-saving and thermal insulation renovation measures for many years, which can be roughly divided into two categories: internal thermal insulation renovation of external walls and external thermal insulation renovation of external walls. The interior insulation transformation of the exterior wall is to place the insulation layer on the inside ...

Problems solved by technology

The disadvantage is that the construction is inconvenient, the wall is easy to crack, and the wall cannot be ventilated

[0004] After searching the existing technology, it was found that the US Patent Document No. US3,789,747A: Ventilated Acoustic Structure Panel (ventilated hollow structure wall panel), although this technology can complete wall ventilation, it does not use solar energy and requires a motor to complete ventilation; China Patent document number CN201507055U, announcement date 2010-06-16, records a double-layer curtain wall with external air circulation. This technology realizes wall ventilation using solar energy in glass curtain walls, and has not been applied in existing building renovations. And did not consider the roof renovation plan
