Problems solved by technology

Although this method can play a certain role in fire resistance, its durability is poor. Under the action of weathering, rock wool and glass wool are easy to be damp and fall off, resulting in failure and pollution of fire resistance protection. The disadvantages are obvious.

Embodiment Construction

[0019] The present invention will be described in detail below in combination with specific embodiments.

[0020] The invention relates to a light-weight fire-resistant roof structure. The structure includes a roof panel 1, purlins 3, fireproof cloth 4 and aluminum alloy battens 5; The cloth 4 is fixed to the purlin 3 through the aluminum alloy bead 5 . The roof panel 1 is a metal profiled plate.

[0021] Roof panels 1 and purlins 3 are connected by inner metal self-tapping screws 2 . The inner metal self-tapping screws 2 are evenly arranged along the purlin 3 direction.

[0022] The purlins 3 are galvanized square steel pipes arranged longitudinally and parallelly under the roof panel 1 . The aluminum alloy bead 5 is an aluminum alloy bead, and its position and direction correspond to the purlin 3 .

[0023] The aluminum alloy bead 5 fixes the fireproof cloth 4 to the purlin 3 through the outer metal self-tapping screws 6 . The outer metal self-tapping screws 6 are evenl...

Abstract

The invention relates to a light fire-resistant roof structure. The light fire-resistant roof structure comprises a roof panel, purlines, fireproof cloth and aluminum alloy pressing strips, wherein the roof panel is fixed to the upper portions of the purlines, the fireproof cloth is laid on the lower portions of the purlines, and the fireproof cloth is fixed to the purlines through the aluminum alloy pressing strips; and the purlines and the roof panel are fixed through self-tapping screws, and the aluminum alloy pressing strips and the purlines are fixed through self-tapping screws. The technical means of combining multiple layers of fire-resistant materials is adopted, the high temperature of a fire can be effectively blocked, the fire resistance of the roof structure is achieved, and the fireproof requirement is met; and roof structure measures are easy to construct and convenient to install, the light fire-resistant roof structure is a technical improvement of a light roof structure, and obvious advantages are achieved.

Description

technical field [0001] The invention relates to the field of steel structure building construction, in particular to a light fireproof roof structure. Background technique [0002] At present, steel structure buildings are developing vigorously in our country, especially in industrial and mining enterprises, logistics warehousing, and transportation fields. In the design of steel structures, the roof is an important building component, and its fireproof structure lacks practice references. In the current design, flame-retardant materials such as glass wool and rock wool with a certain fire-resistant time are generally used for protection. Although this method can play a certain role in fire resistance, its durability is poor. Under the action of weathering, rock wool and glass wool are easy to be damp and fall off, resulting in failure and pollution of fire resistance protection. The disadvantages are obvious. Contents of the invention [0003] The object of the present ...
