Description

Technical Field

[0001] The present application relates to a corrugated door core board, belonging to the field of door core manufacturing. Background Art

[0002] The problem of wooden door deformation has always been a technical problem that persists and is difficult to overcome in the industry. After exploration and experiments, it is known that the core of the deformation of wooden door leaves is the door core filler. In the current wooden door manufacturing, in order to save wood resources and to achieve some lightweight, efficient, beautiful and cost-saving purposes, this is usually done. First, make the wooden door core, then fill the space in the middle of the wooden door core, and finally perform surface edge sealing on the wooden door core, so that an indoor wooden door is quickly made. For example, the Chinese patent with application number CN206707569U mentions a door core board and a door with the door core board, wherein a core body is set in the door, and the core body is two layers of magnesia board and a foam board interlayer is set between the two layers of magnesia board to bond them together. This kind of solid door has a great price advantage because it uses less solid wood, and it is still widely available in the actual market. However, when the wooden door core of this kind of wooden door is made, sometimes in order to reduce the quality or get a similar experience to that of a solid wood door, fillers are generally mixed in the door core board. In the existing wooden door structure, there is no scientific door core board arrangement process, which causes the wooden door leaf to deform. The main reason is that the internal structure is unstable, and the product is affected by the climate in different geographical locations, resulting in thermal expansion and contraction. The board undergoes physical changes, and after long-term use, it will deform and crack, affecting the structural strength and aesthetics of the solid wood door. Therefore, a new corrugated door core board has become a problem that technicians in this field need to solve urgently. Utility Model Content

[0020] The present application is described in detail below with reference to embodiments, but the present application is not limited to these embodiments.

[0021] like Figure 1 - Figure 4 As shown, the utility model provides a corrugated door core board, comprising:

[0022] Door frame 1 is a hollow cubic structure;

[0023] The door core assembly 10 fills the hollow area of ​​the door frame 1, and the door core assembly 10 is bonded to the inner wall of the door frame 1;

[0024] The door core assembly 10 is a five-layer sandwich structure, including a first support plate 2, a first corrugated plate 5, a second support plate 3, a second corrugated plate 6 and a third support plate 4 which are bonded in sequence.

[0025] The first support plate 2, the first corrugated plate 5, the second support plate 3, the second corrugated plate 6 and the third support plate 4 are all carbon fiber plates.

[0026] It should be noted that the thickness of the first support plate 2, the second support plate 3 and the second support plate 4 are all 4 mm, and the sandwich layer of the first support plate 2 and the second support plate 3 is glued to the first corrugated board 5, and the thickness of the sandwich layer of the first support plate 2 and the second support plate 3 is 17 mm, that is, the thickness of the first corrugated board 6 is 17 mm, the thickness of the second corrugated board 16 is also 17 mm, and the second corrugated board 16 is the sandwich layer of the second support plate 3 and the third support plate 4.

[0027] Please continue to refer to Figure 2 As shown, the first corrugated board 5 and the second corrugated board 6 are corrugated structures arranged opposite to each other, and the arched parts of the first corrugated board 5 and the second corrugated board 6 form a rhombus-shaped area.

[0028] The first corrugated board 5 and the second corrugated board 6 are both composed of a plurality of first inclined boards 7 , a plurality of second inclined boards 8 and a plurality of connecting boards 9 , and one first inclined board 7 and one second inclined board 8 are symmetrically arranged relative to one connecting board 9 .

[0029] The first corrugated board 5 is sandwiched between the first support board 2 and the second support board 3 to form a cavity structure 11 between the first support board 2 and the second support board 3 . The first corrugated board 5 is bonded to the first support board 2 and the second support board 3 through a plurality of connecting boards 9 .

[0030] The second corrugated board 6 is sandwiched between the second support board 3 and the third support board 4 to form a cavity structure 11 between the second support board 3 and the third support board 4 . The second corrugated board 6 is bonded to the second support board 3 and the third support board 4 through a plurality of connecting boards 9 .

[0031] It is worth noting that the first corrugated board 5 and the second corrugated board 6 are formed by adding a softener to the board core and soaking it for softening treatment. The softening time is divided into three times, each time for 2 hours. The first softening is 9 mm; the second softening is 13 mm; the third softening is 17 mm. After three softenings, the board is placed in a steel plate mold for forming.

[0032] The rhombus-shaped area makes the door core assembly 10 more stable and more resistant to shock and deformation when it is bonded to the inside of the door frame 1 .

[0033] The cavity structure 11 is filled with sound insulation cotton, that is, the sound insulation cotton is filled in the middle of the five-layer sandwich structure to make the door more soundproof. A fireproof coating can also be applied on the outside of the door frame to enhance safety and practicality.

[0034] The above are only a few embodiments of the present application and do not constitute any form of limitation to the present application. Although the present application is disclosed as above with preferred embodiments, it is not intended to limit the present application. Any technician familiar with the profession, without departing from the scope of the technical solution of the present application, using the technical content disclosed above to make slight changes or modifications are equivalent to equivalent implementation cases and fall within the scope of the technical solution.
