Description

Composite door not easy to deform

Technical Field

The utility model relates to the technical field of door leaves, in particular to a composite door which is not easy to deform.

Background

Doors are switchable structures used in buildings. In order to make the door lighter, wooden materials are typically used. For ordinary household wooden doors, the conventional structure is to arrange some fillers in the space of the door core frame and then seal the two sides with wooden door plates. The wooden door structure is not firm enough at the filler part and is easy to crash and deform.

Chinese patent CN202023117948.5 discloses a fire door, wherein the filler is aluminum honeycomb, and the door panels and the frame surrounding the periphery of the aluminum honeycomb are both of metal structure, so that the fire door has heavy mass and high cost.

Chinese patent CN202022866530.8 discloses a sandwich honeycomb aluminum wood door with a decorative surface, in this case a multi-layer structure, which is complicated in structure and troublesome to assemble, although the structural stability is relatively good.

There is therefore a need to provide a new composite door structure that addresses the above issues.

Disclosure of Invention

The utility model mainly aims to provide a composite door which is not easy to deform, can enable a door leaf to have better rigidity and permeability resistance, and is simple in structure, firm and durable.

The utility model realizes the aim through the following technical scheme: the utility model provides a non-deformable's composite door, includes the door core and is located the timber board on door core two sides, the door core include the door core frame, fill in the aluminum honeycomb in door core frame interior space with locate the metal sheet on door core frame two sides, the thickness of aluminum honeycomb equals the thickness of door core frame, the edge laminating of metal sheet in the edge of door core frame, the timber board laminating in the outside of metal sheet.

Specifically, the thickness of the metal plate is 0.3-1mm.

Specifically, at least one crosspiece is included in the door core frame, the metal sheet with the crosspiece laminating.

Further, the door core frame is made of wood materials, the door core frame is attached to the metal plate through epoxy glue, and the door core frame is attached to the edge of the wood door plate through white latex.

Further, wood strips are attached to the edges of the door core frames.

The technical scheme of the utility model has the beneficial effects that:

the aluminum honeycomb is adopted in the composite door to provide the strength of the hollow part of the door core frame, the metal plate is used for surrounding the aluminum honeycomb, and the rigidity and the permeability resistance of the door are improved, so that the composite door has lower cost, simple structure and firmness and durability.

Detailed Description

The present utility model will be described in further detail with reference to specific examples.

Examples:

as shown in fig. 1 and 2, the composite door with difficult deformation comprises a door core and wooden door plates 4 positioned on two sides of the door core, wherein the door core comprises a door core frame 1, aluminum honeycombs 2 filled in the inner space of the door core frame 1 and metal plates 3 arranged on two sides of the door core frame 1, the thickness of the aluminum honeycombs 2 is equal to that of the door core frame 1, the edges of the metal plates 3 are attached to the edges of the door core frame 1, and the wooden door plates 4 are attached to the outer sides of the metal plates 3. The aluminum honeycomb 2 is a hollow-out structure material, and after being placed in the space of the door core frame 1, the structural strength of the vacant position can be improved, the metal plates 3 are used for sealing the two sides of the aluminum honeycomb 2, so that moisture is prevented from penetrating into the aluminum honeycomb 2, the rigidity and the permeability resistance of the door are improved, and the composite door is low in cost, simple in structure, firm and durable.

As shown in fig. 2, the thickness of the metal plate 3 is 0.3-1mm. The metal plate 3 mainly plays a role in packaging and protecting the aluminum honeycomb 2, so that a large thickness is not required, and the quality of the whole door leaf can be reduced. The galvanization can lead the antirust performance to be better, and the warping of the door leaf caused by the infiltration and corrosion of moisture is avoided.

As shown in fig. 1 and 2, the door core frame 1 includes at least one rail 11, and the metal plate 3 is attached to the rail 11. The door core frame 1 is less likely to deform after the crosspiece 11 is added, and the rigidity is better under the condition that the metal plates 3 are added and connected.

As shown in fig. 1, the door core frame 1 is made of a wood material, the door core frame 1 and the metal plate 3 are bonded by epoxy glue, and the edges of the door core frame 1 and the wood door plate 4 are bonded by white latex. The door core frame 1 made of wood materials is lighter than metal materials in weight, is more convenient to connect with the wood door plate 4 by white latex, and has higher connection strength. And door locks, hinges and the like are additionally arranged on the edges of the door leaves, and the door core frame 1 made of wood materials is more beneficial to processing lock holes and hinge grooves.

As shown in fig. 1, the edge of the door core frame 1 is also attached with a wood edge strip 5. The wood edge strip 5 is used for thickening the edge of the door core frame 1, and the thickness of the wood edge strip 5 can be reworked and thinned to a required thickness. Because the door core frame 1 and the wood edge strips 5 are made of wood materials, the door core frame is convenient to process a lock hole and a hinge groove, and the connection strength of the door core frame and the wood edge strips is high.

What has been described above is merely some embodiments of the present utility model. It will be apparent to those skilled in the art that various modifications and improvements can be made without departing from the spirit of the utility model.
