Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments.

Examples of which are illustrated in the accompanying drawings, wherein like reference numerals refer to the same or similar elements or elements having the same or similar function throughout. The embodiments described below with reference to the drawings are exemplary and intended to be used for explaining the present invention, and should not be construed as limiting the present invention.

Referring to fig. 1-3, a low gram weight PVC board of high strength, includes plate body 1, and the bonding of plate body 1 surface has the film, plate body 1 middle part is equipped with cavity 11 (extrusion moulding) that prolongs 1 length direction of plate body a plurality of support risers 12 that do not connect of shaping in the cavity 11 correspond in the cavity 11 the department of truncation 13 of supporting riser 12 is inserted and is equipped with backup pad 2 for play the effect of strengthening plate body 1 intensity, even under the relatively thin condition of plate body thickness, set up backup pad 2 and can play reinforcing plate body 1 intensity to a certain extent, anti buckling capacity and compressive capacity all can obtain improving promptly, and the raw materials that use simultaneously are relatively less.

Referring to fig. 4, in order to further increase the strength, a reinforcing vertical plate 21 is provided (integrally formed) on the top and bottom of the supporting plate 2 to abut against the cavity 11.

Referring to fig. 5 to 7, a clamping groove 3 and a clamping block 4 are respectively arranged on the end side of the plate body 1.

Wherein, joint groove 3 and joint piece all are isosceles trapezoid shape.

As shown in fig. 6, a setting plate 31 is disposed in the middle of the inner side of the engaging groove 3 along the extending direction, a positioning protrusion 32 is fixed at the end of the positioning plate 31, and the thickness of the positioning protrusion 32 is greater than the thickness of the positioning plate 31. Correspondingly, as shown in fig. 7, the middle of the clamping block 4 is provided with an isosceles trapezoid-shaped limiting groove 41 matched with the positioning plate 31, and meanwhile, a positioning groove 42 is formed in the limiting groove 41 for clamping the positioning protrusion 32.
