Problems solved by technology

Since the above-mentioned ceiling panels generally do not exceed 20mm, the ceiling panels will soften, pulverize and fall off in the event of a fire; at the same time, the material of the hanging parts or aluminum or steel will soften or even melt at 400 to 600 degrees Celsius, causing the ceiling to collapse. It is difficult to reach the 1h level in the fire resistance test

Embodiment Construction

[0030] In order to make the purpose of the invention, technical solutions and beneficial effects of the present invention clearer, the embodiments of the present invention will be described below in conjunction with the accompanying drawings. The features in can be combined arbitrarily with each other.

[0031] figure 1 A schematic diagram of a refractory ceiling system, such as figure 1 As shown, the fire-resistant ceiling system includes a fire-resistant board 1, a T-shaped refractory hanger 2, a side-side fire-resistant hanger 3, a side keel 4, and a suspender 5. The side keel 4 is a right-angle keel, and is fixed on the partition wall 6 in the horizontal direction. Component 3 rests on the side keel 4 and is fixed to the partition wall 6. The upper end of the T-shaped refractory hanger 2 is connected to the suspender 5. The refractory board 1 forms a connection with the partition wall 6 by lapping the refractory hanger 3 on the side. The refractory board 1 is assembled w...

Abstract

The invention discloses a fireproof ceiling system. The system comprises hanging rods, a side keel, fireproof boards, T-shaped fireproof hanging pieces and a side fireproof hanging piece; the fireproof board comprises an upper panel, a fireproof filling layer and a decoration base plate which are successively stacked from top to bottom and are integrated; four side surfaces of the fireproof board are provided with overlap gaps for accommodating the T-shaped fireproof hanging pieces or the side fireproof hanging piece; the T-shaped fireproof hanging piece comprises inorganic firebricks and a T-shaped metal piece; the side fireproof hanging piece comprises inorganic firebricks and an L-shaped metal piece; the side keel is transversely fixed on a partition wall; the side fireproof hanging piece is abutted to the side keel and is fixed with the partition wall; the T-shaped fireproof hanging piece is connected with the hanging rods; the fireproof board is connected through the overlapping between the fireproof board and the side fireproof hanging piece; the fireproof boards are assembled through the overlapping between adjacent fireproof boards and the T-shaped fireproof hanging pieces. The invention relates to the field of buildings. The invention provides a ceiling system having higher fire-resistance and better heat insulation and sound insulation performance.

Description

technical field [0001] The invention relates to the field of construction, in particular to a fire-resistant ceiling system. Background technique [0002] The living or working environment of the house needs top decoration. Simply put, it refers to the decoration of the ceiling. Artistic image of interior space. In addition, the suspended ceiling has the functions of heat preservation, heat insulation, sound insulation and sound absorption, and it is also the hidden layer of electrical, ventilation and air conditioning, communication and fire protection, alarm pipeline equipment and other projects. In addition to the insulation performance and aesthetics of the suspended ceiling of the house, fire resistance is the most basic and important safety requirement. [0003] The traditional ceiling mode is mostly single-layer ceiling boards such as aluminum gusset boards, gypsum boards, and mineral wool boards. The fixtures installed on the ceiling are in direct contact with the ...
