Description

Technical Field

[0001] The utility model relates to the technical field of door leaf filling structures, in particular to an indoor door leaf filling structure capable of reducing deformation. Background Art

[0002] The most widely used type of interior door leaf in daily life is solid wood door leaf. Due to the high cost of solid wood molding materials, it is difficult for many users to accept it, but because they love the texture of solid wood, it is difficult to make a choice. At the same time, solid wood door leaves are very load-bearing, and the requirements for door frames and hinges are also very high, which will also increase the economic burden of users in disguise. Therefore, in the production process of door leaves, in order to save materials and reduce the weight of wooden doors, a filling structure is needed between the two panels of the wooden door. During the splicing process, solid wood boards are generally used for assembly to give the door leaves the texture and quality of solid wood.

[0003] The existing wooden door filling structure adopts a single wooden strip, which is arranged in multiple layers for filling. However, this filling structure itself is easily affected by moisture and expands, thereby causing the door leaf to deform.

[0004] Therefore, it is particularly important to design an interior door leaf filling structure that can reduce deformation to solve the above-mentioned defects. Utility Model Content

Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.

[0027] Example:

[0028] The embodiment of the utility model provides a filling structure for an indoor door leaf that can reduce deformation. The filling structure for the door leaf is intended to solve the technical problem that a filling structure composed of a single wooden strip in the prior art easily causes deformation of the door leaf.

[0030] First, see Figure 1 , Figure 3 and Figure 4 A filling structure for an indoor door leaf that can reduce deformation includes a door leaf main body 1. The sides of the door leaf main body 1 are fixedly connected with a forward multilayer board 101. The forward multilayer board 101 has good compressive resistance, is not easy to deform and crack, has a very small shrinkage and expansion coefficient, has a good ability to regulate indoor temperature and humidity, and can effectively make up for the defects naturally produced by natural wood. Both sides of the door leaf main body 1 are fixedly connected with panels 102. The panels 102 wrap both sides of the door leaf main body 1 to enhance the aesthetics of the door leaf main body 1 and provide protection for the internal filling structure. The edges and corners of the door leaf main body 1 are fixedly connected with protective corners 1021. The protective corners 1021 can provide protection for the four corners of the door leaf main body 1 and extend the service life of the door leaf main body 1.

[0031] Among them, see Figure 1 , Figure 3 and Figure 4A group of lock wood LVL103 is fixedly connected on the corresponding side between the forward multi-layer boards 101 and located inside the door leaf main body 1. The lock wood LVL103 is convenient for installing holes for door lock components. The size of the lock wood LVL103 is 50*28mm. The lock wood LVL103 is away from the side of the forward multi-layer boards 101 and located inside the door leaf main body 1 and is fixedly connected with a plate waste layer 104.

[0032] For further information, see Figure 1 and Figure 3 The plate waste layer 104 is located on the side away from the lock wood LVL103 and is fixedly connected with a galvanized steel pipe 2 inside the door leaf body 1. The galvanized steel pipe 2 plays the role of a fixed structure, enhances the stability and load-bearing capacity of the door leaf body 1, and extends the service life of the door leaf body 1. The length of the galvanized steel pipe 2 is 300mm, and the cross-sectional size of the galvanized steel pipe 2 is 25*25mm.

The composite board layer 3 is made of a multi-layer solid wood composite board. The multi-layer solid wood composite board is pressed by overlapping multiple layers of solid wood materials. It has good stability, flame retardancy and durability. It will not shrink or deform even when encountering large humidity and temperature changes, and can effectively avoid deformation of the door leaf main body 1 caused by environmental factors.

[0034] For further information, see Figure 1-Figure 3 A graphite homogeneous composite plate 4 is fixedly connected between the composite plate layers 3 on both sides and inside the door leaf main body 1. The graphite homogeneous composite plate 4 is composed of a graphite homogeneous plate 401 and a honeycomb plate interlayer 402. The graphite homogeneous plate 401 has good sound insulation and noise reduction, flame retardancy, heat insulation and moisture resistance, which greatly reduces the hygroscopicity of wood, thereby shortening the shrinkage and swelling of wood, and effectively improves the deformation of the door leaf caused by moisture changes. A honeycomb plate interlayer 402 is fixedly connected between the graphite homogeneous plates 401. The honeycomb plate interlayer 402 has the characteristics of light weight, high strength, sound insulation, heat insulation and moisture resistance, which greatly reduces the weight of the door leaf main body 1 and enhances the force strength of the filling structure.

[0036] The working process of the utility model is as follows: first, the panel 102 packages both sides of the door leaf body 1, which enhances the aesthetics of the door leaf body 1 and provides protection for the internal filling structure. The protective corner 1021 can provide protection for the corners of the door leaf body 1. The galvanized steel pipe 2 plays the role of a fixed structure, enhances the stability and load-bearing capacity of the door leaf body 1, and extends the service life of the door leaf body 1. The composite board layer 3 of the multi-layer solid wood composite board material has good stability, flame retardancy, and durability. It will not shrink or deform when encountering large humidity and temperature changes, and effectively avoids deformation of the door leaf body 1 caused by environmental factors. The graphite homogeneous plate 401 has good sound insulation and noise reduction, and is resistant to The fire-proof, heat-insulating and moisture-proof properties reduce the hygroscopicity of wood, thereby shortening the shrinkage and swelling of wood, and effectively improving the deformation of the door leaf main body 1 caused by moisture changes. The honeycomb panel interlayer 402 inside the graphite homogeneous composite plate 4 has the characteristics of light weight, high strength, sound insulation, heat insulation and moisture resistance, which greatly reduces the weight of the door leaf main body 1 and enhances the stress strength of the filling structure. The entire operation process is simple and convenient. Compared with the existing door leaf filling structure, the utility model can effectively avoid the deformation of the door leaf due to environmental factors through design, and enhance the overall structural stability and stress strength of the door leaf, while reducing the overall weight of the door leaf and enhancing the sound insulation and heat insulation of the door leaf.
