Description

Technical Field

[0001] The utility model relates to the technical field of door structures, and more specifically to a door core board and a door leaf. Background Art

[0002] The door core board is a material used to fill wooden doors, anti-theft doors and other doors. The door core board is the main filling material inside the door leaf, which not only affects the quality and performance of the door leaf, but also affects the aesthetics and practicality of the door leaf.

[0003] Traditional door core panels are generally one-piece structures made of core panel materials such as bridge arch mechanical panels or ordinary graphite homogeneous panels. However, door core panels made of the above materials are prone to water absorption and deformation, which can cause bulging of the entire door leaf. At the same time, due to their low strength, the overall door core panel is prone to aging and deformation, affecting the appearance and practicality of the door leaf.

[0004] Therefore, how to reduce the deformation of the door core board and improve the strength of the door core board has become a technical problem that needs to be urgently solved by technical personnel in this field. Utility Model Content

[0005] In view of this, the purpose of the utility model is to provide a door core board to reduce the deformation of the door core board and improve the strength of the door core board.

[0006] Another object of the utility model is to provide a door leaf having the door core plate.

[0007] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0008] A door core board, comprising:

[0009] The core plate body comprises at least two core plates connected by splicing, and the core plate has two side surfaces arranged opposite to each other, and reinforcing meshes are laid on both side surfaces of the core plate.

[0010] Optionally, in the above-mentioned door core panel, a plurality of weight-reducing holes are arranged at intervals in the core panel body.

[0011] Optionally, in the above-mentioned door core panel, arc-shaped grooves are arranged at intervals on the core panel, so that the arc-shaped grooves of adjacent core panels are spliced ​​to form the weight-reducing holes.

[0012] Optionally, in the above-mentioned door core panels, the core panels are stacked and the weight-reducing holes are arranged on the end faces of the core panel bodies.

[0013] Optionally, in the above-mentioned door core panel, the weight-reducing holes are arranged through-through along the length direction of the core panel body.

[0014] Optionally, in the above-mentioned door core panel, the reinforcing net includes a mesh cloth, and the mesh cloth is adhered to the inner surface of the weight-reducing hole and the outer surface of the core panel body.

[0015] Optionally, in the above-mentioned door core panel, the mesh cloth is one of resin glass fiber mesh cloth, carbon fiber mesh cloth, glass fiber mesh cloth, basalt fiber mesh cloth or polyester fiber mesh cloth.

[0016] Optionally, in the above-mentioned door core board, the core board body is one of magnesium oxysulfide board, perlite board or glass magnesium board.

[0017] Optionally, in the above-mentioned door core panels, adjacent core panels are bonded and connected; and / or,

[0018] The reinforcing mesh is bonded to the surface of the core plate.

[0019] A door leaf, comprising a door core panel as described in any one of the above items.

[0020] The door core board provided by the utility model is formed by splicing two or more core boards to form a core board body, and reinforcing nets are laid on two opposite sides of each core board, so that when the core board body absorbs water and deforms, the restraining effect of the reinforcing nets laid on each core board reduces the deformation of each core board, thereby reducing the deformation of the entire core board body. At the same time, since multiple layers of reinforcing nets are formed on the core board body, not only the deformation of the entire core board body is reduced, but also the strength of the core board body is improved.

[0021] Compared with traditional door core panels, the door core panels provided by the utility model have reinforcing meshes laid on two opposite sides of each core panel, thereby forming multiple layers of reinforcing meshes on the core panel body. By constraining the deformation of each core panel, not only the deformation of the entire core panel body is reduced, but also the strength of the core panel body is improved, thereby ensuring the beauty and practicality of the door leaf.

[0031] The core of the utility model is to provide a door core board to reduce the deformation of the door core board and improve the strength of the door core board.

[0032] Another core of the utility model is to provide a door leaf having the above-mentioned door core board.

[0033] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0034] Door leaves are usually composed of door core board, upper head, middle head, lower head and side stiles. As an important element for separating indoor and outdoor spaces, the structure and composition of door leaves play a decisive role in the functionality and aesthetics of the door. Door leaves not only need to have a certain strength and stability, but also need to meet multiple requirements such as sound insulation, heat preservation and aesthetics.

[0035] Door core panels are made of a variety of materials, including but not limited to solid wood, density boards, honeycomb boards, bridge mechanical boards or common graphite homogeneous boards. Traditional door core panels are generally one-piece structures made of the above materials, which makes them easy to absorb water and deform during use, causing bulging of the entire door leaf. At the same time, due to their low strength, the door core panel is prone to overall aging and deformation, affecting the aesthetics and practicality of the door leaf.

[0036] In order to reduce the deformation of the door core board, improve the strength of the door core board, and ensure the aesthetics and practicality of the door leaf, such as Figures 1 to 6 As shown, the embodiment of the utility model discloses a door core panel, including a core panel body 100 .

[0037] Among them, Figures 1 to 3 As shown, the core panel body 100 includes at least two core panels 101 connected by splicing, and each core panel 101 has two side surfaces arranged opposite to each other. For the convenience of understanding, two core panels 101 are taken as an example for explanation and illustration, and the two side surfaces of the core panel 101 arranged opposite to each other are defined as the first side surface and the second side surface, respectively. The first side surface of the core panel 101 is the splicing surface with the adjacent core panel 101, and the second side surface of the core panel 101 is the outer side surface of the core panel body 100. By laying a reinforcing mesh 102 on the two opposite side surfaces of each core panel 101, that is, laying a reinforcing mesh 102 on the first side surface and the second side surface of the core panel 101, respectively, four layers of reinforcing mesh 102 are formed on the core panel body 100 formed by splicing two core panels 101, so as to improve the strength of the core panel body 100. At the same time, through the reinforcing mesh 102 on both sides of each core panel 101, it can restrain the expansion and deformation of the core panel 101, which can effectively prevent the door leaf from bulging and other phenomena, thereby ensuring the aesthetics and practicality of the door leaf. It should be noted that the number of core panels 101 can be but is not limited to two. It can be understood by relevant technicians in this field that the more core panels 101 there are, the higher the strength of the core panel body 100 in the splicing direction, and the stronger the ability of the core panel body 100 to resist deformation in the splicing direction, but the thickness of the core panel body 100 in the splicing direction is correspondingly thicker, thereby increasing the thickness of the door leaf. Therefore, the specific number of core panels 101 needs to be determined according to the actual usage scenario and customer needs.

[0038] In a specific embodiment, if Figure 3 As shown, the reinforcing mesh 102 is bonded to the surface of the core plate 101, that is, the first side and the second side of the core plate 101, and each core plate 101 is stacked, and adjacent core plates 101 are fixedly connected by bonding. Of course, adjacent core plates 101 can also be connected and fixed by fasteners, such as horse nails or round nails. Specifically, Figure 1 and Figure 2As shown, the reinforcing net 102 includes a mesh cloth 1021, and the mesh cloth 1021 is attached to the first side and the second side of the core board 101 and fixed by an adhesive. In this embodiment, the mesh cloth 1021 can be one of but not limited to resin glass fiber mesh cloth, carbon fiber mesh cloth, glass fiber mesh cloth, basalt fiber mesh cloth or polyester fiber mesh cloth. At the same time, the core board body 100 can be one of but not limited to magnesium oxysulfide board, perlite board or glass magnesium board. Preferably, the core board body 100 adopts magnesium oxysulfide board, so that the door leaf filled with the door core board has hydrophobicity and will not be deformed due to changes in moisture content. The core board body 100 using magnesium oxysulfide board has high strength and has a certain correction effect on deformation. It also has high hardness and A2 fireproof advantages, and has good sound insulation effect.

[0039] The door core panel provided by the utility model has reinforcing meshes 102 laid on two opposite sides of each core panel 101, thereby forming a multi-layer reinforcing mesh 102 on the core panel body 100. By constraining the deformation of each core panel 101, not only the deformation of the entire core panel body 100 is reduced, but also the strength of the core panel body 100 is improved, thereby ensuring the aesthetics and practicality of the door leaf.

[0040] Furthermore, if Figures 4 to 6 As shown, in order to realize the lightweight design of the door leaf and ensure that the door leaf has a good sound insulation effect, in a specific embodiment, a plurality of weight-reducing holes 103 are arranged at intervals on the core plate body 100, and the weight-reducing holes 103 are arranged on the end surface of the core plate body 100, and the weight-reducing holes 103 are arranged through the length direction of the core plate body 100, and the mesh cloth 1021 is attached to the inner surface of the weight-reducing hole 103 and the outer surface of the core plate body 100. Specifically, as Figure 6As shown, arc grooves 1031 are arranged at intervals on each core plate 101, and the arc grooves 1031 extend from one end of the core plate 101 to the other end of the core plate 101 along the length direction of the core plate 101, and the mesh cloth 1021 is respectively attached to the side of the core plate 101 where the arc grooves 1031 are located, that is, the first side of the core plate 101, so that the mesh cloth 1021 is attached to the inner wall of the arc groove 1031 and the outer side of the core plate 101, that is, the second side of the core plate 101, so that when adjacent core plates 101 are spliced, weight-reducing holes 103 are formed at the positions of the arc grooves 1031 of the adjacent core plates 101, and it is ensured that the inner surface of the weight-reducing hole 103 and the outer surface of the core plate body 100 are paved with mesh cloth 1021. By setting the weight-reducing holes 103, not only the lightweight design of the door leaf is achieved, but also the door leaf is ensured to have a good sound insulation effect. In addition, by fitting the mesh cloth 1021 on the inner surface of the weight-reducing hole 103 and the outer surface of the core panel body 100, the strength of the door core panel is improved and the deformation of the door core panel is reduced, thereby solving the problem of weakening the strength of the core panel body 100 due to the provision of the weight-reducing hole 103.
