Embodiment 1

[0034] A fire-resistant door frame that can be easily assembled, including a door frame base and a door panel step arranged on the door frame base; Frame 1, a base sleeve set on the steel inner frame 1 and adapted to the outer contour of the steel inner frame 1; the steel inner frame includes buckle edges 13 facing the side of the wall and located on both sides of the notch, The seat edge 14 facing the side of the door leaf and parallel to the buckle edge, and the outer edge 15 and the inner surface edge 16 vertically connecting the buckle edge and the seat edge; The step cover 3 arranged on the fireproof block; the position corresponding to the fireproof block on the base cover is provided with a vacant section for making the fireproof block directly attached to the surface of the seat edge, and the surface of the fireproof block attached to the surface of the seat edge is the connecting surface , the step cover includes a three-piece connected cover edge on the three surface...

Embodiment 2

[0038] The difference from the above-mentioned embodiment is that there is a concave groove formed on the outer edge, and the corresponding groove position on the base cover is concavely formed to fit the groove and can be inserted into the groove to cover the wall of the groove. It is used to clamp the door pocket bayonet 41 of the door pocket. A decorative layer is covered on the outer surface of the base cover and the step cover, and 1-3 card slots are arranged on the outer edge.

Embodiment 3

[0040] The difference from the above embodiment is that the card slot is a square card slot, and the bayonet of the door pocket is a square bayonet.

Abstract

The invention belongs to the field of fireproof doors and particularly relates to a fireproof door frame which is simple in structure and can be simply and easily assembled from various profiles. The fireproof door frame comprises a door frame base and a door panel retaining step, wherein the door frame base comprises a steel inner frame and a base sleeve sleeving the steel inner frame; the steel inner frame comprises buckle sides, a base side, an outer face side and an inner face side; the door panel retaining step comprises a fireproof block and a retaining step sleeve sleeving the fireproof block; the base sleeve is provided with a gap section, and the retaining step sleeve comprises three sleeve sides which are integrally connected; a snapping groove which is concavely formed is formed in the outer face side, and a door sleeve snap port adapted to the snapping groove is concavely formed in the base sleeve. The fireproof door frame can be quickly, simply and easily assembled from the steel inner frame, the base sleeve, the retaining step sleeve and the fireproof block, and the processing is very convenient; meanwhile, the snapping groove is formed in the door frame base, so that the door frame and a door sleeve can be connected in a snapped manner, the mounting for workers and the locating of the door sleeve are facilitated, and meanwhile, the fixed strength of the door sleeve is enhanced.

Description

technical field [0001] The invention belongs to the field of fire doors, and in particular relates to a fire door frame with simple structure and easy assembly through various profiles. Background technique [0002] The traditional fireproof door frame adopts the method of layer-by-layer fireproof material pressing and shaping, and then wrapping the surface material, and then spraying paint on the surface material. The process is complicated, the construction period is long, and the production is troublesome. There are also steel door frames. It is not specified, the shape is cumbersome, and multiple electric welding is required. The welding positioning and dimensional accuracy are required to be high. After welding, the surface of the connection point is not smooth. The pattern and color of the door frame need to be sprayed later. The processing is difficult and the processing accuracy is high. The sprayed color and the door body cannot be in the same style, resulting in ma...
