Detailed description of the invention
For making the purpose of this utility model, technical scheme and advantage clearer, below in conjunction with accompanying drawing, this utility model is described in further detail.
See Fig. 1 and 2, this utility model embodiment provides a kind of co-extruded plastic-wood ceiling board, and including main wall plate 1, main wall plate 1 is rectangular configuration, being provided with through hole 6 in main wall plate 1 along its length, main wall plate 1 middle part, side (right side) outwards (to the right) in the width direction is prominent forms tenon 2.Said structure is essentially identical with existing ceiling board, difference is: the top and bottom of main wall plate 1 opposite side (left side) in the width direction the most outwards (to the left) extends formation upper flange 3 and lower wing plate 4, upper flange 3 and lower wing plate 4 are oppositely arranged and constitute the groove 5 coordinated with tenon 2.Wherein, main wall plate 1, tenon 2 and upper flange 3 use conventional plastic-wood material one extrusion molding, and it is mainly composed of PVC, calcium powder, powder of straw and auxiliary agent etc., and wherein, the mass content of PVC is about 50%.Lower wing plate 4 is used for installing rifle nail 7, and it uses the material co-extrusion of higher than main wall plate 1 intensity (being more firmly installed rifle nail 7 it can be understood as hardness is higher) on main wall plate 1；Specifically, the main component of lower wing plate 4 is also PVC, calcium powder, powder of straw and auxiliary agent etc., but the mass content of PVC is about 70%, and other components reduce accordingly, preferably by fixing for rifle nail, and will not be able to ftracture.
Wherein, seeing Fig. 1 and 2, the tenon 2 in this utility model embodiment is the rectangular block architecture arranged along main wall plate 1 width (left and right to).
Wherein, seeing Fig. 1 and 2, upper flange 3 and lower wing plate 4 in this utility model embodiment are rectangular block shape structure, and the upper surface of upper flange 3 is parallel with the upper surface of main wall plate 1, and its lower surface is parallel with tenon 2 upper surface；The lower surface of lower wing plate 4 is parallel with the lower surface of main wall plate 1, and its upper surface is parallel with tenon 2 lower surface.
Wherein, seeing Fig. 1 and 2, the length being shorter in length than lower wing plate 4 of the upper flange 3 in this utility model embodiment, correspondingly, (short under upper length) is matched in the side (right side) of main wall plate 1 with its structure.
Wherein, the degree of depth of the groove 5 in this utility model embodiment is slightly larger than the length of tenon 2.
Preferably, seeing Fig. 2, the tenon 2 in this utility model embodiment uses than main wall plate 1 intensity higher material co-extrusion on main wall plate 1, and the material of tenon 2 can be consistent with the material of lower wing plate 4.
Wherein, seeing Fig. 1 and 2, the through hole 6 in this utility model embodiment is the rectangular through-hole arranged along main wall plate 1 length direction；Specifically, rectangular through-hole is arranged side by side along the width of main wall plate 1.
Wherein, the thickness of the main wall plate 1 in this utility model embodiment is 8-12mm, is specifically as follows 9mm, and its width is 140-180mm, is specifically as follows 158mm；The a length of 8-15mm of tenon 2, its thickness is 2.5-3.5mm；The a length of 25-40mm of through hole 6, its width is 3-6mm；The thickness of upper flange 3 is 3-5mm, and the thickness of lower wing plate 4 is 3-5mm.
Wherein, seeing Fig. 1 and 2, the upper surface press mold of the main wall plate 1 in this utility model embodiment has one layer of wallpaper 8, does not use gluing, and uses hot pressing overlay film, it is possible to reduce the release of formaldehyde.
Further, the upper surface of the main wall plate 1 in this utility model embodiment is provided with a plurality of groove along its length.
This utility model provides a kind of co-extruded plastic-wood ceiling board, for installing the lower wing plate employing material co-extrusion more higher than main wall plate intensity of rifle nail at main wall plate on this ceiling board, specifically, PVC content in lower wing plate is higher, rifle nail can more be firmly mounted on ceiling board and not have the abnormal conditions such as cracking, ensure that the installation moulding wood ceiling board, and extend the service life of ceiling board.
The foregoing is only preferred embodiment of the present utility model, not in order to limit this utility model, all within spirit of the present utility model and principle, any modification, equivalent substitution and improvement etc. made, within should be included in protection domain of the present utility model.
