Abstract
The utility model discloses a kind of central layer of labeled door; described central layer comprises haydite concrete layer and is arranged at the reinforcing bar netted reinforcing rib in haydite concrete layer; the first reinforcing bar that described steel mesh reinforcement reinforcing rib comprises horizontally set and the second reinforcing bar longitudinally arranged; the surface of described haydite concrete layer is provided with metal level, and what haydite concrete layer inside was provided with two or more longitudinal extension subtracts matter through hole.The central layer production technology of this labeled door is simple, and has very strong fireproof performance.
Description
Technical field
The utility model relates to a kind of central layer of labeled door.
Background technology
Labeled door refers to the door that can meet fire stability, integrality and thermal insulation within a certain period of time and require.It is located between fire compartmentation, fire separation thing that emergency staircase, vertical shaft etc. have certain refractoriness.Labeled door, except the effect with common door, has more the effect stoping fire spreading and flue gas diffusion, can stop spreading of the intensity of a fire within a certain period of time, guarantee evacuating personnel.Divide by material and have fire-proof wooden door, fire resistance steel door, steel wood labeled door, other labeled doors etc.Other labeled doors refer to and adopt the inorganic non-combustible material except steel, difficult firebrand material or difficult firebrand material products or part to adopt steel, difficult firebrand material, difficult firebrand material products to make doorframe, door leaf skeleton, door skin, if the labeled door of the interior packing material of door leaf.Existing anti-fire door core board is with expanded perlite, inorganic soluble ceramic beaverboard, calcium silicate board material mostly, its formula constituent and complex manufacturing.
Utility model content
The technical problems to be solved in the utility model, structure is more simple more to provide one, produces anti-fire door core board more easily.
The utility model is achieved in that
A kind of central layer of labeled door; described central layer comprises haydite concrete layer and is arranged at the reinforcing bar netted reinforcing rib in haydite concrete layer; the first reinforcing bar that described steel mesh reinforcement reinforcing rib comprises horizontally set and the second reinforcing bar longitudinally arranged; the surface of described haydite concrete layer is provided with metal level, and what haydite concrete layer inside was provided with two or more longitudinal extension subtracts matter through hole.
Wherein, the cross section of matter through hole is subtracted described in for circular or square.
Wherein, described metal level is cold rolling hot dip galvanizing steel plate.
Wherein, subtract described in matter through hole and be filled with sound insulation and noise reduction cotton.
Wherein, the first reinforcing bar and the second reinforcing bar are screw-thread steel.
The utility model tool has the following advantages: the utility model anti-fire door core board adopts haydite concrete to be main material, and process of manufacture is simple, and has very strong fire resistance; Bury the structural strength that reinforcing bar netted reinforcing rib substantially increases anti-fire door core board in haydite concrete layer underground, haydite concrete layer bag surface bag is provided with metal level, has effectively completely cut off central layer and has contacted with the direct of burning things which may cause a fire disaster, further increased fire stability.
Accompanying drawing explanation
Fig. 1 is the structural representation of anti-fire door core board in the utility model one embodiment;
Fig. 2 is the cross section view of anti-fire door core board in an embodiment.
Label declaration:
1-haydite concrete layer; 2-metal level; 3-subtracts matter through hole; 41-second reinforcing bar;
42-first reinforcing bar.
Detailed description of the invention
By describing technology contents of the present utility model, structural feature in detail, realized object and effect, accompanying drawing is coordinated to be explained in detail below in conjunction with embodiment.
Refer to Fig. 1 and Fig. 2, a kind of central layer of labeled door, the reinforcing bar netted reinforcing rib that described central layer comprises haydite concrete layer 1 and is arranged in haydite concrete layer, the first reinforcing bar 42 that described steel mesh reinforcement reinforcing rib comprises horizontally set and the second reinforcing bar 41 longitudinally arranged, the surface of described haydite concrete layer 1 is provided with metal level 2, in haydite concrete layer 1 be provided with two or more longitudinal extension subtract matter through hole 3;
Wherein, described in subtract matter through hole cross section for circular, described metal level is cold rolling hot dip galvanizing steel plate.Certainly, in other embodiments, the cross section of described matter through hole also can be square or oval, the metals such as the stainless steel that described metal level also can be common.
The beneficial effect of the utility model anti-fire door core board is: the utility model anti-fire door core board adopts haydite concrete to be main material, and process of manufacture is simple, and has very strong fire resistance; Bury the structural strength that reinforcing bar netted reinforcing rib substantially increases anti-fire door core board in haydite concrete layer underground, haydite concrete layer bag surface bag is provided with metal level, has effectively completely cut off central layer and has contacted with the direct of burning things which may cause a fire disaster, further increased fire stability.
In one embodiment, subtract described in matter through hole and be filled with sound insulation and noise reduction cotton.Described sound insulation and noise reduction cotton can be asbestos or glass fibre cotton, and these two kinds of sound insulation and noise reduction cottons not only have good noise reduction, and have very strong resistance to elevated temperatures.
In one embodiment, the first reinforcing bar 42 and the second reinforcing bar 41 are screw-thread steel, and the first reinforcing bar and the second reinforcing bar can adopt welding manner to be connected also can to tie up letter mode with iron wire and connect, and the diameter of the first reinforcing bar and the second reinforcing bar is 2-6mm.
In another embodiment, in order to improve fireproof performance further, between described haydite concrete layer 1 and metal level 2, be also provided with non-woven fabrics enhancement Layer.
The foregoing is only embodiment of the present utility model; not thereby the scope of the claims of the present utility model is limited; every utilize the utility model manual and accompanying drawing content to do equivalent shapes or Structural Transformation; or be directly or indirectly used in other relevant technical fields, be all in like manner included in scope of patent protection of the present utility model.
