Description

Door leaf structure of multilayer door core

Technical Field

The utility model relates to a door leaf structure of multilayer door core belongs to building door and window field.

Background

With the increasing environmental protection requirements of buildings, steel doors are widely used in the current building field. The basic structure of the steel door is a door frame, a door leaf and accessories. The structure of the door leaf determines most of the properties of the steel door. Steel doors, a common building component, must meet the requirements of strength, air-tightness, water-tightness, sound insulation, heat preservation, non-flammability, fire resistance, etc. The structure of the door leaf is an important factor that determines the performance of the steel door, such as sound insulation, fire resistance, and non-flammability.

For example, steel doors used in hospitals, offices, etc. nowadays, a single-layer paper honeycomb is generally used as a core material for supporting a door panel in order to achieve the purposes of basic strength, convenient production, and light weight. However, the obvious disadvantage is that the sound insulation and heat preservation performance is not good. The sound wave can be transmitted to the hexagonal cavity of the honeycomb through the vibration of the panel of the door leaf, and the air of the honeycomb cavity is driven to vibrate. The air vibrations drive the door plant vibrations of opposite side to realize the transmission of sound. The heat preservation performance is also because a communicating space is formed between the two surfaces of the door leaf, so the heat preservation and heat insulation performance is relatively low.

Disclosure of Invention

An object of the utility model is to overcome the not enough of above-mentioned prior art existence, provide a door leaf structure of multilayer door core.

The utility model adopts the technical proposal that: the utility model provides a door leaf structure of multilayer door core, includes the door leaf, the door leaf comprises positive panel of door leaf, door leaf backplate and curb plate all around, its characterized in that: a gap is reserved between the door leaf front panel and the door leaf back panel, two or more layers of filling materials are arranged in the gap, an interlayer is arranged between the filling materials, and the filling materials are separated by a partition plate in the interlayer.

Furthermore, the number of layers and the material of the filling material are selected according to the performance and the grade required by the door panel; can be paper honeycomb, aluminum honeycomb, corrugated, extruded sheet, rock wool, glass wool, refractory material plate, etc., and can be made of the same material or different materials. The interlayer material (partition board) is also one or more of a paperboard, a fireproof plate, a metal plate or a film according to the requirement.

The utility model has the advantages that: the utility model discloses with original individual layer honeycomb structure, become two-layer or multilayer core structure. Other media such as paper boards, steel plates, fire-proof plates and the like are filled among the core material structures, so that the transmission (sound insulation) of sound waves can be blocked, and the performance grades of strength, fire resistance and heat preservation can be improved. The panel, the core material and the separator are glued by using an adhesive to form an integral structure.

The utility model discloses can obviously improve intensity, syllable-dividing, fire-resistant, the fire-resistant performance of ordinary honeycomb core door plant. Improving the competitiveness of the associated products.

Drawings

In order to more clearly illustrate the embodiments of the present invention or the technical solutions in the prior art, the drawings needed to be used in the description of the embodiments or the prior art will be briefly described below, it is obvious that the drawings in the following description are only some embodiments of the present invention, and for those skilled in the art, other drawings can be obtained according to these drawings without inventive exercise.

Fig. 1 is a schematic structural diagram of the present invention.

Labeled as: the door comprises a door leaf 1, a door leaf front panel 2, a door leaf back panel 3, a filling material 4, an interlayer 5, a door lock 6 and a hinge 7.

Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

As shown in fig. 1, the door leaf structure of the multilayer door core comprises a door leaf 1, wherein the door leaf 1 is composed of a door leaf front panel 2, a door leaf back panel 3 and peripheral side panels, a gap is reserved between the door leaf front panel 2 and the door leaf back panel 3, two or more layers of filling materials 4 are arranged in the gap, an interlayer 5 is arranged between the filling materials 4, and the filling materials 4 are separated by adopting a partition plate in the interlayer 5.

In this embodiment, the number of layers and the material of the filling material are selected according to the performance and the grade of the door panel. The filling material can be one or more of paper honeycomb, aluminum honeycomb, corrugated, extruded sheet, rock wool, glass wool and refractory material plate. The interlayer material (partition board) is also one or more of a paperboard, a fireproof plate, a metal plate or a film according to the requirement.

The structure changes the original single-layer honeycomb structure into a core material structure with two or more layers. Thus, the sound transmission (sound insulation) can be blocked, and the performance grades of strength, fire resistance and heat preservation can be improved. Can be widely used on the door leaves of steel doors used in hospitals, offices, houses and the like.
