Abstract

The utility model relates to a finger-joint type core-board, which is designed to resolve the problems that the existing square butt joint type core-board can not be adhered firmly, the flexural strength is not high, and the crack and deformation appear easily. The structure is that a board core is clipped between the two layers of panels, wherein the board core is formed by assembling core strips, the ends of the core strips for the assembled board core is opened with a jogged bell socket, the butt joints of the ends of the core strips are adhered by glue, and the lateral surface of the core strips is put into a press after being glued and is pressed to adhere to be a board core. The finger-joint type core-board has the advantage that the flexural strength and pressive strength are improved obviously; therefore, the core-board can be used as the board for decoration and the plank stuff for manufacturing furniture, thereby expanding the serviceable range and increasing economic benefit.

Description

Finger formula core-board
Technical field
The utility model relates to a kind of splicing sheet material, specifically a kind of finger formula core-board.
Background technology
Stipulate among existing national standard " core-board " GB/T5849-2006 that as the core bar of core-board plate core, its end face slit is not more than 3mm.This just means that mostly the core bar end face of plate core is not applying glue, even and if applying glue since its that to be cross section at the core bar carry out is bonding, thereby also be difficult to together two core bar strong bond that connect.Therefore, existing core-board plate core, no matter it is that the employing splicing also is non-splicing, core bar end all is with seam discontinuous.This length that has just reduced made core-board is to bending resistance and load performance.And the detection of above-mentioned standard itself exactly can not reflect these performances of core-board.So, present commercially available core-board, the overwhelming majority is used for finishing, and almost can not be used for making furniture.In addition, common core-board, core bar length is very little, and not only production efficiency is extremely low, and the class of the production board of working it out is not high yet.
The utility model content
The purpose of this utility model just provides a kind of finger formula core-board, with the overall performance of raising plate core and the mechanical property of core-board, the quality of upgrading core-board, the range of application of expansion core-board.
The utility model is achieved in that a kind of finger formula core-board, accompanies the plate core that forms by core bar assembly group in the middle of two-layer panel, and the core bar end of assembly group plate core has the zigzag bell socket, and core bar end joint sticks with glue and is connected together.
The end of core bar that the utility model is organized assembly some wide uniform thickness of plate core is split into zigzag with gulleting machine, splicing becomes the straight elongated core bar (hereinafter to be referred as " rectangular ") that reaches the requirement of core-board length dimension after the applying glue, press on some described rectangular sides are again after the applying glue, make rectangular bondingly mutually by pressurization, be processed into whole the plate core that reaches the length and width dimensional requirement thus; After this carry out again the processing of follow-up cladding plate core-board.The utility model also can once be gone up press with upper and lower panel and be processed into core-board after some described rectangular side applying glues.
The utility model is to leave the zigzag opposing teeth in the end of described core bar by gulleting machine, constitutes bell socket.The isometric wide and even distribution of the opposing teeth of core bar end is so that any grafting of profile of tooth end face of the two core bars that connect all can be docked tightly.Above-mentioned what is called " opposing teeth isometric " is meant that the height (being leg-of-mutton height) of the profile of tooth of formation equates; So-called " opposing teeth wide " is meant that the tooth root width (being leg-of-mutton base) of each profile of tooth of formation equates.
Core bar in the utility model by finger mode socket joint connect into rectangular after, its every stress performance is substantially near the mechanical property of integral core bar, so be made into after the plate core is reprocessed into core-board, the length of made core-board obviously strengthens to bending resistance, compression strength.Because rectangular that constitutes the plate core is seamless splicing formula and connects, the mechanical property of finished product sheet material width also is greatly increased, therefore, this core-board not only can be used as panel, make the sheet material that furniture is used but also can be used as, the scope of application enlarges, the corresponding raising of economic benefit.
This mode of the utility model by finger mode socket joint connection-core bar, it is rectangular the core bar splicing of varying length can be become reliable quality, so just can not be subjected to the requirement restriction of " spacing of joints between the adjacent core bar is not less than 50mm " this standard code, this just means, the plate core of core-board can be produced by a kind of mechanical system, has not only improved the utilization rate of timber thus, and has reduced labour intensity, having improved work efficiency, is to achieve many things at one stroke.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
The specific embodiment
As shown in Figure 1, the utility model is the core bar 3 that earlier lath is cut into wide uniform thickness, leaves isometric wide and equally distributed sawtooth at the two ends of each core bar 3 with gulleting machine then, constitutes jagged bell socket.After applying glue between the end tooth of core bar 3, splice to become and reach the straight elongated core bar that the core-board length dimension requires.Press on the side of elongated core bar is again after the applying glue makes elongated core bar bonding mutually by pressurization, thereby is processed into whole plate core 2 that reaches the length and width dimensional requirement.On plate core 2, carry out cladding plate processing at last again, make upper and lower deck panels 1 cover upper and lower faces respectively at whole plate core 2, thus core-board.

Claims (3)

1, a kind of finger formula core-board accompanies the plate core (2) that forms by core bar assembly group in the middle of two-layer panel (1), it is characterized in that the end of the core bar (3) of assembly group plate core has the zigzag bell socket, and core bar end joint sticks with glue and is connected together.
2, finger formula core-board according to claim 1, the described core bar (3) that it is characterized in that some wide uniform thickness by the end gluing be spliced into straight rectangular, some described rectangular by the mutual bonding one-tenth plate cores of side gluing (2).
3, finger formula core-board according to claim 2 is characterized in that the isometric wide and even distribution of sawtooth on each end bell socket of described core bar (2).
