Abstract
Description
Technical Field
[0001] This utility model relates to the field of glued laminated timber, and specifically to a glued laminated timber profile with a honeycomb structure. Background Technology
[0002] Wooden profiles are widely used in the home furnishing industry for flooring core materials, door core panels, wall structures, and other structures. Because pure wood structures have high requirements for the quality and specifications of the wood, the cost of pure solid wood profiles is high. In contrast, glued laminated timber profiles use adhesives to bond small pieces of wood together to form larger wooden profiles, which reduces the requirements for the quality and specifications of the raw wood materials and effectively reduces material costs.
[0003] The wood raw materials commonly used for floor cores, door cores, and wall structures are mostly softwoods, such as pine. Pine grows quickly, has coarse and soft plant fibers, is low in cost and light in weight. However, it is precisely because of its fast growth rate and coarse plant fibers that its hardness and stability are relatively weak, making it prone to deformation during use. Utility Model Content
[0004] To address the problem of easy deformation in existing cork-based wood profiles, this invention provides a glued laminated timber profile with a honeycomb structure. This increases the structural strength of the glued laminated timber profile while reducing its weight, thus enabling full utilization of the wood.
[0005] The technical objective of this utility model is achieved through the following technical solution:
[0006] A glued laminated timber profile with a honeycomb structure includes a first base plate and a second base plate bonded together, each base plate comprising at least one layer; an A plate and a B plate are alternately bonded together along the extension direction of the first base plate, the fiber direction of the A plate being perpendicular to the fiber direction of the B plate, and a plurality of honeycomb holes are provided along the fiber direction of the B plate, the honeycomb holes penetrating both sides of the B plate along the fiber direction; a C plate and a D plate are alternately bonded together along the extension direction of the second base plate, the fiber direction of the C plate being perpendicular to the fiber direction of the D plate.
[0007] Furthermore, the honeycomb cells are circular, elliptical, or regular polygonal in shape, and are evenly distributed on plate B.
[0008] Furthermore, the thickness of the first base plate is greater than the thickness of the second base plate.
[0009] Furthermore, the edges of the bonding surfaces of plates A and B are aligned, and the edges of the bonding surfaces of plates C and D are aligned; the area of a single plate B is larger than the area of a single plate A along the extension direction of the first base plate.
[0010] Furthermore, glued laminated timber profiles can be made by sandwiching a second baseboard between two first baseboards.
[0011] Furthermore, glued laminated timber profiles can also consist of two second baseboards sandwiching a first baseboard between them.
[0012] Furthermore, along the direction perpendicular to the thickness of the first and second base plates, the thick side of the glued laminated timber profile is provided with a protruding joint, and the other side is provided with a groove that mates with the protruding joint.
[0013] Furthermore, a fireproof layer is also provided on the outside of the glued laminated timber profile.
[0014] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0015] 1. This utility model uses the bonding connection between the first base plate and the second base plate. The second base plate provides support for the first base plate with honeycomb holes, which increases the strength of the first base plate and makes the overall structure of the glued laminated timber profile more stable, reducing the risk of structural deformation during subsequent use.
[0016] 2. The fibers are arranged perpendicularly between boards A and B, and between boards C and D. The mutually perpendicular fibers interact with each other to form a restraint, which prevents the boards from cracking and increases the strength and service life of the boards.
[0017] 3. The honeycomb holes can further reduce the weight of the board. Combined with the second baseboard, it prevents the honeycomb hole area from spreading and cracking, thus increasing the service life of the glued laminated timber profile. The punched material can also be used as filler or for other structural processing. Attached Figure Description

[0032] The technical solution of this utility model will be further described below with reference to specific embodiments:
[0033] Example 1
[0034] A type of glued laminated timber profile with a honeycomb structure, such as Figure 1 As shown, it includes a first base plate 1 and a second base plate 2 bonded together. The first base plate 1 and the second base plate 2 each include at least one layer. In this embodiment, a first base plate 1 and a second base plate 2 are bonded together to form a glued laminated timber profile.
[0035] First baseboard 1 Figure 2 As shown, to better understand the content of this application, a three-dimensional coordinate system is established with the extension direction of the first base plate 1 as the z-axis, the thickness direction of the first base plate as the y-axis, and the x-axis perpendicular to both the y-axis and z-axis. Alternatingly bonded A plates 4 and B plates 5 are sequentially arranged along the extension direction of the first base plate, i.e., along the z-axis. The fiber direction of A plate 4 is perpendicular to the fiber direction of B plate 5, which is also the growth direction of the tree. Figure 2 The fiber direction of plate A 4 is the x-axis direction, and the fiber direction of plate B 5 is the y-axis direction. Several honeycomb holes 3 are provided along the y-axis direction, and the honeycomb holes 3 penetrate both sides of plate B 5 along the fiber direction.
[0036] Second baseboard 2 Figure 3 As shown, to better understand the content of this application, a three-dimensional coordinate system is established with the extension direction of the second base plate 2 as the z-axis, the thickness direction of the second base plate 2 as the y-axis, and the x-axis perpendicular to both the y-axis and z-axis. Alternating C-plates 6 and D-plates 7 are sequentially arranged along the extension direction of the second base plate 2, i.e., the z-axis direction. The fiber direction of C-plate 6 is perpendicular to the fiber direction of D-plate 7. Figure 3 The fiber direction of plate C6 is the x-axis direction, and the fiber direction of plate D7 is the y-axis direction.
[0037] It should be noted that in the first base plate 1, the alternating A plates 4 and B plates 5 along the z-axis are not limited to alternating splicing of one A plate 4 and one B plate 5, but can also be two, three, or four A plates 4 spliced into a large plate, and then alternately spliced with a large plate formed by splicing two, three, or four B plates. Similarly, in the second base plate 2, the alternating C plates 6 and D plates 7 can be single small plates, or several C plates 6 spliced into a large plate, and then alternately spliced with a large plate formed by splicing several D plates 7.
[0038] More specifically, the honeycomb holes are circular, elliptical, or regular polygonal in shape. The honeycomb holes are evenly distributed on the B plate and are formed by mechanical punching. They can also be processed into shapes other than circular, elliptical, or regular polygonal holes as needed.
[0039] It should also be noted that the size of the honeycomb holes 3 is not limited to one specification. Several different specifications of honeycomb holes 3 can be included on the same B board 5, and the shape of the honeycomb holes 3 is also not limited to one type. This can further improve the utilization rate of wood, such as... Figure 4 As shown, several relatively small-sized honeycomb holes are processed within a relatively large honeycomb hole spacing range, and the punched material can also be used for other production applications.
[0040] The thickness of the first base plate 1 and the second base plate 2 can be equal or unequal. Here, the thickness of the first base plate 1 and the thickness of the second base plate 2 should be understood as follows: Figure 2 and Figure 3 The thickness along the y-axis. Preferably, the thickness of the first base plate 1 is greater than the thickness of the second base plate 2.
[0041] Preferably, the edges of the bonding surfaces of A plate 4 and B plate 5 are aligned, and the edges of the bonding surfaces of C plate 6 and D plate 7 are aligned; along the extension direction of the first base plate 1, that is, along the z-axis direction, the area of a single B plate 5 on the plane parallel to the x-axis and z-axis is greater than the area of a single A plate 4.
[0042] When processing and manufacturing the first base plate 1, such as Figure 5 As shown, the layers are first stacked in a manner where the fiber directions of the upper and lower layers are opposite and perpendicular to each other. The upper and lower layers are bonded together with glue, and pressure is applied by equipment such as a hydraulic press to bond the wood together to form a cuboid column structure 8. The cuboid column structure 8 and the first base plate 1 establish a unified three-dimensional coordinate system. The cuboid column structure 8 is cut into several sheet structures 9 along the plane perpendicular to the y-axis and z-axis. The sheet structures 9 have the prototype of the first base plate 1, that is, they form alternating A plates 4 and B plates 5. Then, the sheet structures 9 are punched along the B plate 5 on a punching machine to process several honeycomb holes 3, forming the first base plate 1.
[0043] When processing the second base plate 2, the process is similar to that of the first base plate 1, that is, bonding is used to form a cuboid column structure 8, and then the cuboid column structure 8 is cut into several sheet structures 9 along the direction perpendicular to the plane containing the y-axis and z-axis. Compared with the first base plate 1, the sheet structures 9 are obtained, which is the second base plate 2.
[0044] Example 2
[0045] A type of glued laminated timber profile with a honeycomb structure, such as Figure 6 As shown, a second base plate 2 is sandwiched between two first base plates 1. Adhesive is applied between the first base plates 1 and the second base plates 2 to form an adhesive layer. The adhesive state can be reinforced by C-clamps or the like.
[0046] Example 3
[0047] A type of glued laminated timber profile with a honeycomb structure, such as Figure 7 As shown, a first base plate 1 is sandwiched between two second base plates 2. Adhesive is applied between the first base plate 1 and the second base plate 2 to form an adhesive layer. The adhesive state can be reinforced by C-clamps or the like.
[0048] Example 4
[0049] Application of a honeycomb-structured glued laminated timber profile in walls, such as Figure 8As shown, taking the glued laminated timber profile in Example 2 as an example, the glued laminated timber profile is used as a brick. A single glued laminated timber profile can be used as a brick, or it can be cut into several bricks. In this example, a single glued laminated timber profile is used as a single brick. When using this brick to build a wall, the wall is built vertically along the y-axis of the first base plate, and the upper and lower layers of bricks are bonded together. During construction, the upper and lower layers of bricks can be bonded together as follows: Figure 8 The bricks can be aligned vertically, or the upper and lower layers can be laid in a staggered manner, such as... Figure 9 As shown.
[0050] Preferably, a protruding joint 10 can be provided on one side of the glued laminated timber profile in a direction perpendicular to the thickness of the first base plate 1 and the second base plate 2, i.e., along the y-axis, and a groove 11 that mates with the protruding joint 10 can be provided on the other side. Figure 10 As shown, the groove 11 is formed by cutting a slot directly into the glued laminated timber profile, and the protruding joint 10 is formed by removing part of the glued laminated timber profile and leaving a part uncut. In this embodiment, the length direction of the protruding joint 10 and the length direction of the groove 11 extend along the X-axis, and the protruding joint 11 and the groove 11 are set on the B plate of the first base plate.
[0051] After the wood blocks are assembled to form a wall, a fire-retardant coating, such as a wood structure fire-retardant paint, can be applied to the exterior of the wall. Alternatively, the wood structure fire-retardant paint can be applied before the blocks are assembled into a wall.
[0052] Example 5
[0053] Application of a honeycomb-structured glued laminated timber profile in flooring core material, such as Figure 11 As shown, in the thickness direction of the glued laminated timber profile, that is, along the y-axis direction, a floor panel 12 is laid on at least one side of the glued laminated timber profile along the y-axis direction, and the floor panel 12 is bonded to the glued laminated timber profile.
[0054] Example 6
[0055] Application of a honeycomb-structured glued laminated timber profile in door core panels, such as Figure 12 As shown, glued laminated timber profiles are spliced together in the x-axis and z-axis directions to form a door core panel structure. Then, door panel 13 is installed on both sides in the thickness direction, and a frame structure is added around the perimeter of the door core panel structure.

After reading this specification, those skilled in the art can make non-inventive modifications to this embodiment as needed, but such modifications are protected by patent law as long as they fall within the scope of the claims of the present invention.
