Description

Technical Field

[0001] This application relates to the technical field of wooden door structures, and particularly relates to a keel anti-deformation structure and a wooden door. Background Art

[0002] Due to the inherent internal stress of wood and the changes in factors such as the ambient temperature difference, wooden doors are prone to problems such as cracking and deformation due to thermal expansion and contraction. Existing wooden doors usually use keels to support the wooden doors to improve the anti-deformation ability of the wooden doors and make the wood properties more stable. The existing wooden door keel filling structure usually uses transverse wooden strips and longitudinal wooden strips in cooperation to achieve support. Such a setting has high requirements for the matching dimensions of the wooden strips, and the error value of the wooden strips needs to be less than 2 mm, with high processing accuracy requirements. And the existing wooden door keel filling structure is connected by short wooden strips and long wooden strips. The short wooden strips produced by cutting are difficult to make standard sizes, resulting in a large amount of material waste; while the longer long wooden strips are prone to deformation, resulting in insufficient anti-deformation ability of the keel structure.

[0029] Figure 1 The existing keel filling structure 300 uses the cooperation of transverse wooden strips and longitudinal wooden strips to achieve support. Such a setting has high requirements for the matching dimensions of the wooden strips, and the error value of the wooden strips needs to be less than 2 mm, with high processing accuracy requirements. The existing keel filling structure 300 is connected by short wooden strips and long wooden strips. The short wooden strips produced by cutting are difficult to make standardized sizes, resulting in relatively large material waste; while the longer long wooden strips are prone to deformation, resulting in insufficient anti-deformation ability of the keel structure.

[0030] The following refers to Figures 2 to 3 Describe a keel anti-deformation structure according to an embodiment of the present application.

The setting that the multiple combined pressing keels 200 are staggered and distributed on both sides of the keel framework 100 can shorten the length of a single combined pressing keel 200. It can not only prevent deformation caused by excessive length but also standardize the control of the length of the combined pressing keel 200, save materials, and improve the material utilization rate. The up-and-down fitting setting can also ensure the connection strength between the two combined pressing keels 200, avoid insufficient strength at the splicing part, and improve the deformation-resistant strength. It can be understood that in some embodiments, the two combined pressing keels 200 are in up-and-down fitting through glue.

[0032] According to some embodiments of the present application, the main keel includes a longitudinal keel framework 120 and a transverse keel framework 110.

[0035] According to some embodiments of the present application, there are eight combined press-fitting keels 200, and the eight combined press-fitting keels 200 are arranged in a staggered manner on both sides of the keel frame 100. Specifically, the ends of every two adjacent combined press-fitting keels 200 are arranged in an upper and lower fitting manner. Therefore, the eight combined press-fitting keels 200 arranged in a staggered manner on both sides of the keel frame 100 will form four groups of connected wholes, which are arranged in sequence in the keel frame 100 to support the keel frame 100 and improve the anti-deformation strength of the keel frame 100.

[0036] According to some embodiments of the present application, multiple combined press-fitting keels 200 are distributed in a staggered manner on both sides of the keel frame 100. The combined press-fitting keels 200 are divided into two sections and connected by upper and lower fitting. Specifically, in some embodiments, the length of the combined press-fitting keel 200 is less than 1 m, which can not only prevent deformation caused by too long length, but also standardize the length control of the combined press-fitting keel 200, save materials and improve the material utilization rate.

[0037] According to some embodiments of the present application, the length of the portion where two combined pressing keels 200 are attached to each other up and down is greater than or equal to 150 mm. The combined pressing keels 200 are arranged in a staggered manner on both sides of the keel frame 100, and the ends of two adjacent combined pressing keels 200 are attached to each other up and down.

The setting of the anti-deformation medium density fiberboard 210 can increase the anti-deformation strength of the combined pressing keel 200. Specifically, in some embodiments, the thickness of the anti-deformation medium density fiberboard 210 is 9 mm. It can be understood that the thicker the thickness of the anti-deformation medium density fiberboard 210, the higher the anti-deformation strength of the combined pressing keel 200. It should be noted that, in some embodiments, the anti-deformation medium density fiberboard 210 is attached to the particle board with glue.

[0039] According to some embodiments of the present application, the anti-deformation medium density fiberboard 210 is arranged on the outer side of the particle board, and the combined pressing keel 200 is attached through the particle board on the inner side. The anti-deformation medium density fiberboard 210 is used to increase the anti-deformation strength of the combined pressing keel 200, and the ends of two adjacent combined pressing keels 200 are attached to each other up and down. Specifically, the anti-deformation medium density fiberboard 210 is arranged on the outer side of the particle board, and the combined pressing keel 200 is attached through the particle board on the inner side.
