Abstract
Description
Technical Field
[0001] The utility model relates to the field of fire door related products, in particular to a fireproof structure of a fire door opening. Background Art
[0002] The primary function of a fire door is to prevent the spread of fire and smoke through its fire resistance in the event of a fire, buying valuable time for evacuation and fire rescue. Therefore, any structural openings, such as holes, that compromise the fire resistance of a fire door should be considered a safety hazard.
[0003] At present, the steel structure of the box and the keel wall form a fire door opening. In order to ensure the fire resistance of the box, fire retardant paint is applied on the surface of the steel structure and the light steel keel, which is inconsistent with the interior decoration and unsightly. The fire door opening is sealed by filling fire retardant glue, which may have the risk of debonding. The fire protection is not strict and cannot meet customer needs. Utility Model Content
[0004] The purpose of the present invention is to provide a fireproof structure for a fireproof door opening to solve the problems raised in the above background technology.
[0005] To achieve the above-mentioned objectives, the present invention provides the following technical solutions: a fireproof structure of a fire door opening comprises a light steel frame wall and a box steel structure, the light steel frame wall is provided with an installation opening, the box steel structure is fixedly installed in the installation opening, a fire door is fixedly installed in the box steel structure, gypsum boards are provided on both sides of the box steel structure, the gypsum boards are fixedly connected to the light steel frame wall and the box steel structure by a plurality of fixing nails, a gap is provided between the box steel structure and the fire door, the gap is filled with a first fireproof sealant, a gap is provided between the gypsum board and the fire door, the gap is filled with a second fireproof sealant.
[0006] Preferably, the plurality of fixing nails are all self-tapping nails.
[0007] Preferably, the first fireproof sealant and the second fireproof sealant are both expansion fireproof sealants.
[0008] Preferably, the gypsum board is a fireproof gypsum board, and the thickness of the gypsum board is 15 mm.
[0009] Preferably, the diameter of the gap between the gypsum board and the fire door is 10 mm.
[0010] Compared with the prior art, the beneficial effects of the present invention are:
[0011] The fireproof structure of the fire door opening is formed by installing a box steel structure in a light steel keel wall to form a fire door opening structure system, installing a fire door inside the box steel structure, installing anti-gypsum board edging on both sides of the box steel structure, fixing it to the light steel keel wall and the box steel structure through multiple fixing nails, filling a first fireproof sealant in the gap between the fire door and the box steel structure, and filling a second fireproof sealant in the gap between the fireproof gypsum board edging and the fire door to ensure fire tightness. The utility model effectively isolates the direct contact between the flame and the box structure, while ensuring the consistency of interior decoration, and can form two fire protection systems, with strict fire protection and guaranteed fire protection performance.
