Problems solved by technology

[0004] According to the different installation orientations of the door panels of fire doors, the door panels can be divided into the fire-facing side and the back-fire side. In the event of a fire, the fire-facing side is heated first, so the mechanical strength and performance requirements of the fire-facing side and the back-fire side are slightly different. , especially the refractory filler layer, while the existing general refractory filler layer is integrally poured, which cannot meet this difference requirement

Embodiment Construction

[0013] Referring to the drawings, an improved fire door of the present invention includes a fire-resistant filler layer and a support frame 1 distributed around the periphery of the fire-resistant filler layer. As for other layer structures, existing technologies can be used, such as refractory plate layers on both sides of the fire-resistant filler layer 4. The side of the refractory board layer 4 facing away from the refractory filler layer is provided with a surface decoration layer 5.

[0014] The refractory filler layer is a double-layer structure, and the side facing the fire-back surface is divided into several areas by the reinforcing frame 2. Each area is filled with a monolithic prefabricated refractory block 3; the layer 6 facing the fire-back surface is composed of refractory Pouring materials.

[0015] The inside of the support frame 1 is divided into a number of areas by the reinforcing frame 2, and each area is filled with a whole piece of prefabricated refractory bl...

Abstract

The invention discloses an improved fireproof door. The improved fireproof door comprises a fireproof packing layer and a supporting frame distributed around the periphery of the fireproof packing layer, the fireproof packing layer is of a double-layer structure, one layer of the fireproof packing layer facing a side exposed to fire is divided into a plurality of areas through a reinforcing framework, a whole prefabricated fireproof building block is filled in each area, and the other layer of the fireproof packing layer facing the side unexposed to fire is formed by pouring fireproof materials. Since the fireproof door combines difference requirements of the performances of the side exposed to fire and the side unexposed to fire of a door plate, the fireproof packing layer is improved specifically, the problem of thermal expansion of the side exposed to fire is considered while the mechanical strength requirement of the side unexposed to fire is also considered, and the improved fireproof door is wider in application.

Description

Technical field [0001] The invention relates to a door, in particular to a fire-resistant door with fire-resistant and heat-insulating functions. Background technique [0002] Fire doors are widely used in the field of construction and are installed at the entrances and exits of passages or spaces with fire protection requirements. The existing fire doors are mostly five-layer structures, consisting of a fire-resistant filler layer, a fire-resistant sheet layer located on both sides of the fire-resistant filler layer, and The surface decoration layer on the side of the plate layer facing away from the refractory filler layer is composed of a support frame around the periphery of the refractory filler layer in order to support and facilitate the formation of the refractory filler layer. [0003] The surface decoration layer can be made of natural wood or synthetic materials according to the requirements of aesthetics, etc., which does not require high technical requirements. The key...
