Embodiment

[0017] Example: see figure 1 , figure 2 , a heat-insulating composite fire door, comprising a door leaf 1, a door frame 2 and a hinge 3, one side of the door leaf 1 is hinged to the door frame 2 through a hinge 3, and the hinge 3 adopts a fireproof hinge 3; A fire-proof door closer 7 is also provided between the upper end of 2 and the upper end of the door leaf 1, through which the door leaf 1 can be closed in time to avoid the spread of fire and the diffusion of smoke. The door leaf 1 includes a frame body 11 formed by a face plate, a back plate and a side plate. In the frame body 11, a fire-proof frame 12 is respectively provided near the two side plates. The fire-proof frame 12 includes several fire-resistant plates parallel to the face plate. and the multi-layer boards located between the fire-resistant boards, the fire-resistant boards and the multi-layer boards are alternately distributed and bonded together by high-temperature-resistant glue. In the cavity formed by ...

Abstract

The invention discloses a thermal-insulating combined fire door comprising a door leaf, a door frame and hinges. The door leaf comprises a frame, fireproof ribs are arranged within the frame near two side plates, and a chamber formed by a face plate, a back plate and the fireproof ribs is filled with an inorganic fireproof core plate. The section of the door frame is in a step form. When the door leaf is closed, the side plates of the door leaf are in contact with a concave face of the door frame, and the door leaf is wholly embedded into the door frame. The face, in contact with the door leaf, of the door frame is provided with a groove; the bottom of the groove is provided with thermal-insulating holes; a fireproof seal pad is disposed in the groove and raised from the groove. The thermal-insulating combined fire door is better in thermal insulation, deformation resistant and accordingly better in fire resistance.

Description

[0001] technical field [0002] The invention relates to a fireproof door, in particular to a heat-insulating composite fireproof door. Background technique [0003] The current steel fire doors are mainly composed of two parts, the door frame and the door leaf. Traditional steel fire doors are made of all steel materials. The fire and heat insulation performance of steel fire doors is a huge test for steel fire doors, and now Some steel fire door core materials have serious corrosion damage to steel plates, and a large number of steel fire doors have rusted in less than 2 years after being installed and used on site. At the same time, the thermal conductivity of the traditional steel fire-resistant door plate is high. When a fire occurs, it is easy to cause the temperature of the back-fired surface of the door leaf to be high, and it is easy to cause the door leaf to deform, thus failing to meet the performance requirements of the fire-resistant door. Contents of ...
