Description

Novel labeled door

Technical field

The utility model relates to a kind of door, relates in particular to a kind of safety door that can play heat insulation, fire prevention, Smoke prevention effect.

Background technology

Labeled door is the key facility that plays fire prevention, Smoke prevention, heat insulation, partition effect, can effectively stop fire spread and Flue Gas Diffusion, strives for the time that fire-fighting is put out the fire, to ensureing that people's lives and properties play an important role.According to increasingly serious fire-fighting situation, country's issue has recently implemented new labeled door standard.At the requirement of the fire resistance among the new standard GB 12955-2008, the heat-insulating fireproof door fire resistance period is 1.5 hours, until 3 hours, compares traditional labeled door performance, is not difficult to find out that the Fire-proof lock position is the position of labeled door overall structure most fragile.Because traditional Fire-proof lock is installed in the middle of the door leaf, must in door leaf, unblank body opening, tapered end hole, inside and outside handle feedthrough hole etc., the button box hole of on doorframe, must unblanking, and destroy the fire-proof smoke-proof bar of labeled door sidewall simultaneously, make labeled door not have intensity, not Smoke prevention, not fire-resistant at the Fire-proof lock position, if in fire, the Fire-proof lock position of labeled door will be to smolder at first and go here and there the position of fire, can't reach the requirement of new labeled door standard and the purpose of guarantee people's lives and properties.Have again, traditional flame resistant glass is contained in the middle part of fire-proof door leaf, and flame resistant glass is generally thicker, makes the fire prevention press strip thickness deficiency on both sides, when labeled door under detection case, because of being inactive state, flame resistant glass can not come off, but in actual scene of fire, after reaching uniform temperature, when the glazing bead of counter-fire face was fired, one had the vibrations flame resistant glass to split away off easily, and labeled door just can't play the effect of partition.

Summary of the invention

The purpose of this utility model is to overcome the deficiencies in the prior art, thereby develops a kind of novel labeled door that can play really every cigarette, fire insulation effect.

Above-mentioned technical problem of the present utility model is mainly solved by following technical proposals: a kind of novel labeled door, has door leaf, the fire prevention form is arranged on the door leaf, and there is doorframe the door leaf outside, and the fire prevention hinge is arranged between door leaf and the doorframe, the fire prevention lockset is arranged on the door leaf, keeper is characterized in that: described fire prevention lockset is by bottom-locking plate, the lock cap assembly that links to each other with bottom-locking plate, be positioned at the independent fire prevention lock body among bottom-locking plate and the lock cap assembly, the compound plate assembly that is positioned at the bottom-locking plate lateral surface is formed; On the compound plate assembly Fang Xin and connecting rod are housed in described, on the described lock cap assembly tapered end are housed; Described keeper is made up of snap close base plate and the snap close cover plate that is sleeved on the snap close base plate; Described fire prevention lockset is installed on door leaf surface; Described keeper is installed in and the corresponding doorframe of the lockset of the preventing fires outside.

As preferably, on door leaf, the position that the Fang Xin of interior compound plate assembly and connecting rod pass through respectively has an installing hole, and the fire-proof smoke-proof cover is housed in the described installing hole.

As preferably, the longitudinal and transverse cross section of described fire prevention form is a stairstepping, and counter-fire face one side is smaller, carries on the back fiery face one side flame resistant glass is installed.

As preferably, anti-drag hook device is housed between flame resistant glass and door leaf contact surface, at the lateral surface of flame resistant glass and door leaf contact surface the fire prevention press strip is housed.

As preferably, described anti-drag hook device is the stairstepping bonding jumper, and the fire-proof smoke-proof bar is housed between bonding jumper and glass.

Therefore, the utlity model has and do not destroy the labeled door overall structure, make that fire-proof smoke-proof bar on door leaf sidewall, the doorframe sidewall is complete to be enriched, at utmost protect the overall structure of door leaf doorframe, prevent that labeled door from smoldering and go here and there fiery, simple in structure, practical; Be particularly suitable for current high building project labeled door.
