[0002] Fiberboard is a man-made board material, which is mainly made of wood cellulose fibers interwoven and formed by utilizing their inherent adhesive properties. Adhesives and additives can be applied during the manufacturing process. It is usually made from wood processing scraps such as boards, shavings, branches, etc., which are crushed, soaked, and ground into wood pulp, and then a certain amount of adhesive is added. It is made by hot pressing and drying. Fiberboard has the advantages of uniform material, small longitudinal and transverse strength difference, and not easy to crack. It has a wide range of uses and can replace general boards in construction, furniture manufacturing, ships, aircraft, etc.

[0003] The edges of existing fiberboards are relatively fragile and lack corresponding support and protection devices. The edges are easily affected by external forces such as impact and scratches, resulting in damage or deformation. The fiberboards may also deform or crack when subjected to greater pressure or external forces, affecting the use of the fiberboards. At the same time, fiberboards usually require glue or other adhesives when splicing. This splicing method not only prolongs the working time, but also easily causes gaps or unevenness at the joints.

[0025] The effect achieved by the entire embodiment 1 is that the fiberboard body 2 and the baffle 8 are inserted into the frame 1. At this time, the baffle 8 will drive the four blocks 11 to squeeze a group of springs 12 and retract into the first groove 9. After the baffle 8 is fully inserted into the frame 1, the block 11 will be inserted into the second groove 10 under the push of a group of springs 12 to fix the baffle 8 and prevent the fiberboard body 2 from falling off. The frame 1 can also provide protection for the edges of the fiberboard body 2 to ensure the integrity and stability of the fiberboard structure. When different fiberboards need to be spliced, first rotate and remove the two fixing screws 7, and then insert the slider 3 on another frame 1 into the inside of the slide groove 5, and fix the slider 3 in the slide groove 5 by the fixing screws 7. Not only is the fixing method simple, but it can also reduce the time waiting for the adhesive to dry.

[0026] Embodiment 2, as Figure 2-Figure 5 As shown, the fiberboard body 2 includes a wear-resistant layer 210, which adopts a melamine impregnated paper layer and has a thickness of 0.5-1.5 mm. A flame-retardant layer 220 is arranged at the bottom of the wear-resistant layer 210, which adopts a calcium silicate board layer and has a thickness of 5-12 mm. A waterproof layer 230 is arranged at the bottom of the flame-retardant layer 220, which adopts a polymer waterproof film layer and has a thickness of 0.1-1 mm.

[0028] Working principle: When workers need to use the fiberboard, they only need to insert the fiberboard body 2 into the frame 1, and then insert the baffle 8 into the frame 1. At this time, the baffle 8 will first squeeze the four blocks 11, so that the four blocks 11 squeeze a group of springs 12 respectively and retract into the first groove 9. When the baffle 8 is fully inserted into the frame 1, a group of springs 12 will push the blocks 11 into the second groove 10 to fix the baffle 8. The baffle 8 can prevent the fiberboard body 2 from falling off from the frame 1. When workers need to splice different fiberboards, they can first put one on the frame 1. The two fixing screws 7 are rotated and unscrewed, and then the slider 3 on the other frame 1 is inserted into the inside of the slide groove 5, and finally the fixing screws 7 are screwed on to complete the splicing of the two fiberboards. The wear-resistant layer 210 of the fiberboard can provide protection for the fiberboard and extend the service life of the fiberboard. The flame retardant layer 220 can slow down the spread of fire and protect people's lives and property safety. The waterproof layer 230 can reduce the entry of water vapor into the interior of the building and avoid moisture corrosion to the building. The sound insulation layer 240 can weaken external noise. The supporting layer 250 can enhance the structural strength of the fiberboard.
