Building energy-saving heat preservation system and construction method of building heat preservation reverse method

Abstract

The invention relates to a fixing device for a thermal insulating prefabricated slab of a building and a construction method for the thermal insulation of the building by using a reverse building method. The fixing device comprises a U-shaped upper suspension clasp and a U-shaped lower suspension clasp, wherein first and second horizontal arms which extend outwards in the horizontal direction are respectively arranged at both ends of a U-shaped opening of the upper suspension clasp, the upper and lower upper suspension clasps are cross-buckled and connected through thermal insulating balls, part of a nut column is welded on a U-shaped inner vertical arm of the lower suspension clasp, and a hanging ring is screwed inside a screw hole of the nut column. The construction method provided by the invention is simple and convenient and has the cost-saving effect, and a thermal insulating system is sturdy and durable and can effectively solve the common problems in the building that conventional self-insulating hollow blocks are easy to crack caused by inconsistent shrinking percentages after being in butt joint with the thermal insulating slabs of encased columns and beams.

Description

technical field [0001] The invention relates to a building thermal insulation prefabricated board fixing device and a building thermal insulation reverse construction method, belonging to the technical field of building construction methods. Background technique [0002] At present, the existing building insulation systems mainly have the following defects: [0003] 1. Thin plastering external insulation system: (the old traditional method that is still the mainstream today) [0004] 1. There is a defect of short service life. The surface of the insulation board has only a 3 mm thick protective layer. The weather resistance and physical damage ability are difficult to meet the service period of 25 years. Even a few projects begin to have problems 4 months after the completion of the project, and they are not at all It cannot be repaired. In addition, the property rights (use period) of buildings are generally 70 years. Even if the exemption reaches 25 years, how to solve t...
