Abstract
The invention discloses a high-intensity steel fireproof channel door, which comprises a door frame (1) and a door leaf (2), wherein the door frame (1) and the door leaf (2) are connected with each other through a pivot hinge (3) to form the channel door. The high-intensity steel fireproof channel door is characterized in that the door frame (1) comprises a hinge side vertical frame (101), an upper frame (102), a lock side vertical frame (103) and a door sill (104) which are sequentially and fixedly connected with one another to form the square door frame (1). One side, which is provided with the pivot hinge, of the door frame has a clamping slot structure; a stage-type clamping strip is arranged on the hinge side of the door leaf; and after the door leaf is closed, the clamping strip is embedded into the clamping slot to firmly lock the door leaf. By adopting the pivot hinge, the door leaf and the door frame are convenient to mount and adjust, and a door gap is uniform; and a multi-point push rod escape lock and a door locker are arranged on the door, so that in an emergency, people can escape, and the door can be automatically closed.
Description
Technical field
The invention belongs to the building unit technical field, the passway for escaping door that specifically just relates to exist unsteady wind to have a meeting, an audience, etc. well under one's control in the building and close use, instantaneous blast impacts in the time of especially resisting, and has high-intensity steel fireproof passage door.
Background technology
Fast development along with economy, the building trade of China also obtains fast development, major infrastructure project is in full flourish throughout the country, especially Large-scale Railway, subway engineering are constantly built in China big and medium-sized cities, and in carrying out the construction engineering of railway, subway, often carry out the excavation of large tunnel, in perforation place of these railways or subway bidirectional tunnel, because can producing instantaneous blast, the operation of train and wind tunnel effect impact, produce huge impact force.At present, the Gate of installing in the tunnel face is in order to resist instantaneous huge impact force, that all does is very heavy, although satisfied the requirement of resisting in the enormous impact, opens comparatively complicated, when running into the condition of a disasters such as fire, open comparatively slow, the efficient of impact escape, and in case be designed to the form of easily opening, then the wind resistance compressive property is not strong, and the access door pressurized easily is out of shape.
Summary of the invention
Comparatively huge for the Gate volume that install existing tunnel face, cause opening comparatively slowly characteristics in order to adapt to the requirement of resisting huge instantaneous impact, can't satisfy the requirement that can wind resistance can satisfy again fast-escape, the invention provides a kind of high strength steel fireproof passage door, can Wind-Pressure Resistance, can realize quick unlatching again, and possess fire-proof function, satisfy the requirement of passway for escaping.
Technical scheme
In order to realize above-mentioned technical purpose, the present invention designs a kind of high strength steel fireproof passage door, it comprises doorframe and door leaf, and described doorframe and door leaf couple together the composition access door by Pinless hinge with guide member, and it is characterized in that: described doorframe comprises hinge side munnion, upper ledge, lock side munnion and threshold.Hinge side munnion, upper ledge, lock side munnion and threshold are fixedly connected sequentially and form square doorframe.Described hinge side munnion is connected a side and has groove with upper ledge, the two pass fire proof sealing strip is housed in the groove, and described lock side munnion is connected a side enhanced leaktightness spare is housed with upper ledge, in described hinge side munnion and the lock side munnion inner chamber channel-section steel is installed.
Described door leaf comprises a sheet, supports with inner frame in the door sheet, is filled with the fire-resistant door core material in the door sheet inner chamber, is provided with step-like card article in hinge side munnion groove corresponding position on the door leaf.
Pass through the escape lock locking between described door leaf and the doorframe.
Between described upper ledge and the door leaf door closer is housed.
Described doorframe is that the 2mm steel plate is made.
Described channel-section steel specification is 120mm * 53mm * 5.5mm.
Described door sheet is that the thick galvanized steel plain sheet of 1.5mm is made.
Described inner frame specification is 50mm * 50mm * 2.5mm square steel pipe.
Handle is equipped with in the described door sheet outside.
Beneficial effect
It is notch that doorframe of the present invention is installed Pinless hinge with guide member one side, and the door leaf hinge side is established step-like card article, and door leaf cuts out rear card article, and to embed the draw-in groove internal locking firm.Employing Pinless hinge with guide member, door leaf and doorframe are convenient to install, regulate, and can guarantee that crack between a door and its frame is even, configuration multiple spot push rod escape lock and door closer on the door, the autoshutdown of evacuating personnel escape and assurance door when being convenient to emergency.
