Fireproof door frame and manufacturing method thereof

Abstract

The invention relates to a fireproof door frame and a manufacturing method thereof, in particular to a door frame with fireproof function. The fireproof door frame comprises a frame, wherein the outer surface of the frame is provided with fireproof inorganic gelled material coat which is formed by cast-in-place, and the thickness of the inorganic gelled material is larger than 4 mm and smaller than 10 mm; a seal groove is disposed at the contact surface of the frame and a door leaf, a gland strip is arranged in the seal groove, and the gland strip is arranged on the inorganic gelled material coat in the seal groove. The invention has the technical schemes that a fireproof layer is coated on the outer surface of the fireproof door frame, the applied fireproof door frame can be any of the existing frames, the problem that joint cracks among surfaces of the frame have low fireproof capability is solved, the inorganic gelled material adopted has light weight, good fireproof effect and heat and sound insulation, and the problems of gaps and adhesive strength between the frame and the inorganic gelled material are solved by adopting the procedure of pressure treatment.

Description

technical field [0001] The invention relates to a building fire prevention equipment, in particular to a door frame with a fire prevention function. Background technique [0002] At present, fire doors in the prior art mainly focus on fire protection on the door leaf, but do not pay enough attention to the frame of the fire door. Some of them use too many wooden materials, which cannot meet the requirements of the fire protection level, and some do not even use wood materials at the frame. In addition, the position setting of materials in different parts of some frames is not ideal, and some ignore the fire prevention problems at the joints of each frame and the contact surface between the door leaf and the frame, and these places are most prone to fire. Sometimes it becomes a weak link, destroying the overall fireproof performance of fire doors and frames, that is, creating a dike of thousands of miles and collapsing in ant nests.

Problems solved by technology

[0002] At present, fire doors in the prior art mainly focus on fire protection on the door leaf, but do not pay enough attention to the frame of the fire door. Some of them use too many wooden materials, which cannot meet the requirements of the fire protection level, and some do not even use wood materials at the frame. In addition, the position setting of materials in different parts of some frames is not ideal, and some ignore the fire prevention problems at the joints of each frame and the contact surface between the door leaf and the frame, and these places are most prone to fire. When it becomes a weak link, it destroys the overall fire performance of the fire door and the frame, that is, it creates a dike of thousands of miles and collapses in an ant nest.

[0003] At present, the wooden material of the fire door frame is made of wood soaked in a flame retardant and fireproof agent to make the required frame size, and then laminated a fireproof board or a decorative board on the surface, and the laminated layer is glued, nailed, etc. The outer layer of fireproof board also becomes part of the fireproofing of the frame, so that cracks inevitably appear at the joints of the various sides of the frame. Generally, fireproof materials or paint are used to fill the cracks. When a fire occurs, the fire resistance of the cracks It is far lower than other parts, and at this time, the inside is directly wood, and the fire resistance is lower, so the entire fire door will lose its fire protection effect because of partial damage, and some are made of metal shells. The body must be filled with concrete or inorganic cementitious materials according to the requirements, because the process is troublesome and the concrete is generally not added, which brings serious fire hazards

[0004] For example, the applicants' respective application numbers: 94246538.5; 97238059.6; 200710093204.4 disclose a fire-proof door and a frame manufacturing method and structure. The skeleton surface of the door frame is glued with a fireproof board and a decorative board. Although the fireproof performance is good, they all use glass fiber cloth. Does not meet the requirements of the new national GB12955-2008 standard
