Airtight, weather-tight and sound-insulation fire door

Abstract

The invention discloses an airtight, weather-tight and sound-insulation fire door comprising a doorframe and a door leaf, wherein the door leaf is hinged on the doorframe; a door lock is arranged on the door leaf; a first fireproof rubber strip and a second fireproof rubber strip are arranged in a ladder type at an inner-side junction of the door leaf and the doorframe; a watertight rubber strip is arranged at an outermost side of the door leaf; three layers of fireproof boards are arranged in the door leaf at intervals; and ceramic wool is filled between adjacent two layers of fireproof boards. By means of the airtight, weather-tight and sound-insulation fire door, not only fireproofing but also airtight, weather-tight and sound-insulation functions can be realized; the needed weather-tight function is realized so long as the door leaf is closed and a heaven and earth lock is locked; the gaps between the doorframe and the door leaf can be sealed by utilizing the watertight rubber strip and the fireproof strips so that the weather-tight, airtight and sound-insulation functions are achieved; and when a fire happens, the fireproof strips of the doorframe rapidly expand so as to block the flame path and unexposed surface temperature is prevented from rising by utilizing interlayer fireproof materials of the door leaf.

Description

technical field [0001] The invention relates to a sealed fireproof door, in particular to an airtight, weathertight and soundproof fireproof door used in places with high concentrations of flammable and explosive gases such as oil tankers, liquefied gas ships and offshore oil drilling platforms. Background technique [0002] This technology is a supplement to marine fire doors (thin plate structure). Existing marine standards and national standards do not have weathertight fire doors, nor do they have fireproof and airtight structures. This technology focuses on solving the design and use of marine fire doors and simultaneously meeting the functions of weathertightness and sound insulation. Contents of the invention [0003] The object of the present invention is to provide an air-tight, weather-tight and sound-proof fireproof door, which has the characteristics of air-tight, weather-tight, sound-proof and good fire-proof effect. [0004] The purpose of the present invent...
