Fireproofing structure of polyphenyl plate outer-wall outer heat-insulating building system and construction method thereof

Abstract

The invention discloses a fireproofing structure of a polyphenyl plate outer-wall outer heat-insulating building system and a construction method thereof. In the structure, fireproofing isolation strips are arranged between the outer-wall layers and in the peripheries of windows and the exposed corners of the polyphenyl plate outer-wall outer heat-insulating building system and comprise polyphenyl plates at the base layers and expended and vitrified ball heat-insulating mortar covering outside the polyphenyl plates. The construction method comprises the following steps of: cleaning the outer-wall base layers; snapping lines and composing; pasting coated glass-fiber gridding cloth; pasting the polyphenyl plates; smearing the expended and vitrified balls; punching by using anchor bolts and installing anchor bolt nylon sleeves; concealing and verifying heat-insulating plates; smearing bottom mortar; laying the glass-fiber gridding cloth; installing anchor bolts and screwing; smearing topmortar; and constructing outer finishes. The fireproofing isolation strips are additionally arranged on the basis of the polyphenyl plate outer-wall outer heat-insulating building system to isolate flames shooting from the windows and among the outer-door layers from spreading, thereby the fireproofing structure reduces the fire loss of polyphenyl plate outer walls on the basis of meeting the requirement for heat insulation.

Description

technical field [0001] The present invention relates to a building structure and its construction method, more specifically to a fireproof structure and its construction method of a polystyrene board exterior wall external thermal insulation building system. High-rise buildings with flexible facing bricks. Background technique [0002] In recent years, polystyrene board external wall insulation system has been widely used in high-rise buildings because of its simple structure, no indoor area occupation, convenient operation and good energy-saving effect. However, polystyrene boards are not flame retardant. Once a flame occurs, the surface of the polystyrene boards exposed to the air will quickly catch fire and spread, and the height of disaster relief such as fire water cannons is limited. It is basically helpless for high-rise building fires, leading to high-rise building fires. Once it happens, the loss is quite heavy. How to properly improve the external wall structure ...
