Abstract

The utility model discloses a single steel-wood armored door, comprising a door leaf. The door leaf comprises a wood panel, a backing plate, a steel core and a fireproof core plate. The fireproof core plate is wrapped by the steel core, and the front and back sides of the steel core are respectively laminated by the backing plate and the wood panel. The laminating areas of the wood panel, the backing plate, the steel core and the fireproof core plate are equal. The single steel-wood armored door is advantageous in that the backing plate has good laminating performance with the wood panel and the steel core, and the laminating of the wood panel is firmer; when a fire disaster occurs, the fireproof core plate which is wrapped in the steel core and has high flame retardation and heat insulation can effectively obstruct heat, keeping the steel core under quite a low temperature; within the initial stage of lifesaving time range, the steel-wood armored door will not have large deformation, providing best opportunity for external and internal fire-fighting rescue.

Description

Singly open steel wood armoured door

Technical field

The utility model relates to a kind of labeled door, particularly relates to a kind of steel wood armoured door of singly opening.

Background technology

Labeled door generally is divided into fire-proof wooden door and fire resistance steel door, and the former ornamental and functional performance all is superior to the latter, and for example switch is light, the switch impact sound is little etc.; The latter is better than the former on fireproof performance, anti-flaming function.In order to make labeled door have both the instrumentality of timber and steel casement door simultaneously, steel wood armoured door arises at the historic moment.

As the comparatively common steel wood armoured door of singly opening, comprise a door leaf, door leaf comprises wooden boards and steel core, wooden boards is compounded on the front and back of steel core.But there is following problem in the existing steel wood armoured door of singly opening: the one, and wooden boards directly is compounded on the front and back of steel core, is prone to come off, and directly has influence on the function of use of armoured door; The 2nd, steel core heat conduction is fast, at high temperature can produce drastic deformation, makes steel wood armoured door open and close all very difficulty, has seriously hindered the best opportunity of outside and inner fire-fighting and rescue.

The utility model content

In view of this, the purpose of the utility model be to provide a kind of wooden boards compound firmly and can improve fireproof performance singly open steel wood armoured door.

In order to reach above-mentioned purpose, the solution of the utility model is:

A kind of steel wood armoured door of singly opening; Comprise door leaf; Said door leaf comprises wooden boards, backing plate, steel core and fireproof core board; This fireproof core board is wrapped up by this steel core, compound successively this backing plate of difference and this wooden boards on the front and back of this steel core, and the mutual compound area of this wooden boards, this backing plate, this steel core and this fireproof core board equates.

Splicing has polylith wood plaque on the said wooden boards, and the periphery of every block of wooden plaque is arranged with wooden panel, convexes with many circles burr corresponding with the profile of this wood plaque on the upper surface of this wood panel; The outer edge periphery of the said wooden plaque of overlap joint, the thickness of this wood panel and the peripheral thickness attenuation successively of this wood plaque extremely with it from this wood panel.

After adopting said structure, the utility model list is opened steel wood armoured door and had following beneficial effect: one deck backing plate is set between wooden boards and steel core, and backing plate has good composite performance with wooden boards and steel core simultaneously, and wooden boards is compound more firm; Be wrapped with high flame retardant, heat insulation fireproof core board in the steel core, when the condition of a fire takes place when, trap heat effectively; Steel core is remained under the relatively low temperature; In the lifesaving time period in the early stage, the bigger distortion of the steel wood unlikely generation of armoured door is for outside and inner fire-fighting and rescue provide the best opportunity.

The specific embodiment

In order further to explain the technical scheme of the utility model, come the utility model is set forth in detail through specific embodiment below.

Shown in Fig. 1-4; The utility model list is opened steel wood armoured door, comprises door leaf 1, and door leaf 1 comprises wooden boards 2, backing plate 3, steel core 4, fireproof core board 5 and frame; Fireproof core board 5 is wrapped up by steel core 4, respectively compound successively backing plate 3 and wooden boards 2 on the front and back of steel core 4; Wooden boards 2, backing plate 3, steel core 4 and fireproof core board 5 mutual compound areas equate; It wraps up above-mentioned frame on the thickness direction of steel wood armoured door, and above-mentioned frame can adopt steel plate and fit and the identical sheet material of wooden boards 2 materials on its outer surface.Between wooden boards 2 and steel core 4, one deck backing plate 3 is set, backing plate 3 is density board or Liu An wooden splint, and backing plate 3 has good composite performance with wooden boards 2 and steel core 4 simultaneously, and wooden boards 2 is compound more firm.Be wrapped with fireproof core board 5 in the steel core 4; Fireproof core board 5 main expanded perlite, the pre-buried skeletons of adopting are processed through the excess pressure effect with the cementing agent that is suitable for; This fireproof core board 5 has that apparent density is light, coefficient of thermal conductivity is low, chemical stability is good, the serviceability temperature scope is wide, wettability power is little; And characteristics such as nontoxic, tasteless, fire prevention, sound-absorbing are widely used in every profession and trade as fire proofing material.When the condition of a fire took place, trap heat remained under the relatively low temperature steel core 4 effectively, in the lifesaving time period in the early stage, made the bigger distortion of the steel wood unlikely generation of armoured door, for outside and inner fire-fighting and rescue provide the best opportunity.

Splicing has polylith wood plaque 21 on the wooden boards 2, and the periphery of every block of wooden plaque 21 is arranged with wooden panel 22, convexes with the Duo Quan burr corresponding with the profile of wooden plaque 21 on the upper surface of wooden panel 22; From the outer edge of wooden panel 22 to the periphery of the wooden plaque 21 of overlap joint with it, the thickness attenuation successively of wooden panel 22 and wooden plaque 21 peripheries.Wherein, wooden panel 22 is as shown in Figure 2, adopts the section bar of hollow, fits and the identical paster of wooden plaque 21 surface patterns on the surface of this section bar; Perhaps as shown in Figure 3, wooden panel 22 ' adopts to be processed with wooden plaque 21 identical solid wood.Splice plate plaque 21 and wooden panel 22, one are divided into the polylith platelet with the monoblock panel on wooden boards 2, and help making full use of raw material and process, the 2nd, bring more level to change to wooden boards 2, when satisfying function, improve sight.

The product form and the style of the foregoing description and accompanying drawing and non-limiting the utility model, the those of ordinary skill of any affiliated technical field all should be regarded as not breaking away from the patent category of the utility model to its suitable variation or modification of doing.
