Embodiment Construction

[0016] The present invention will be described in detail below with reference to the accompanying drawings. A plurality of U-shaped fire baffles 2 and metal frame connectors 3 are connected together with bolts, a fireproof cover 1 is buckled at the metal frame connectors 3, and flame-retardant and heat-insulating materials 9 are installed in the U-shaped fire baffles 2 . The fire cover 1 and the fire baffle 2 are metal stamping U-shaped buckle cover plates, which are divided into two types with decorative surface treatment and punching treatment. The surface of the metal skeleton connecting piece 3 has a sprayed coating of fireproof paint. The flame-retardant and heat-insulating material 9 is selected from commercially available fireproof materials that meet Class A fireproof requirements.

[0017] The invention separates the connectors from the class A fireproof material, effectively avoiding unsafe factors in the external heat preservation structure caused by defects in the...

Abstract

The invention discloses a fabricated fireproof isolation strip which has the characteristics of good fire-proofing effect and convenience for installation. The fabricated fireproof isolation strip comprises a fireproof cover plate, fireproof baffles, a metal framework connector, a bolt connector and a flame retardant insulation material; multiple U-shaped fireproof baffles are connected with the metal framework connector via bolts; the fireproof cover plate is covered on the metal framework connector; and the flame retardant insulation material is held in the U-shaped fireproof baffles. The fireproof cover plate and the fireproof baffles are metal stamping U-shaped cover plates in a decoration face processing form and a punching processing form. The fabricated fireproof isolation strip has the advantage of systematizing an external thermal insulation fireproof isolation strip on the outer wall in a severe cold region so that the defects of connection problem, safety problem, poor durability, and the like of the traditional isolation strip are overcome.

Description

technical field [0001] The invention relates to the technical field of building fire prevention, in particular to an assembled fireproof isolation belt. Background technique [0002] It has been more than 10 years since polystyrene, polyurethane and other materials have been used to save energy in the external insulation of buildings in severe cold areas. With the frequent occurrence of fires in the construction process of external insulation materials in recent years, the Ministry of Public Security "Interim Regulations on Fire Protection of Civil Building External Insulation Systems and Exterior Wall Decoration" 》In 2009, it was required that the external walls of non-curtain wall buildings should be equipped with fire isolation measures. In 2010, the fire in the teacher's apartment in Jing'an District, Shanghai was caused by igniting the external insulation materials during the renovation and construction process. The fire in Shenyang Wanxin in 2011 even exposed the weakn...
