Technical field
The present invention relates to a kind of wood and mould the longeron of pallet, specifically a kind of special longeron for combined wood-plastic pallet.
Background technology
Wood plastic composite is the new generation of green environment-friendly materials that are surging forward in the world in recent years, wood plastic composite mould pallet for extrusion molding production combination formula wood exactly from Canadian import of technology at first.Combined wood-plastic pallet uses and promotes as pallet the process that lives through more than 10 year, and form self national standard " combination shape wood flat pallet " BB/T0020-2001 (People's Republic of China's packaging industry standard), become side by side one of three major types pallet of pallet with wood composite pallet, plastic pallet.
Existing combined wood-plastic pallet is made up of top bed board, longeron, end bed board etc., the forming method of longeron: extrude, the method such as melting mold pressing, squeezing.Existing planform mainly contains: H-girder, Wang Ziliang, porous rectangular pipe, four directions pipe, its general extrusion molding that adopts is produced, because the restriction of extrusion molding technique can only be same structure shape at length direction, cause for ensureing that bending resistance, shock resistance can only bar structure be designed to the shapes such as both economical I-shaped, king's word, porous be rectangular, cubic, length direction can only be linear pattern, cause common direction wall ratio thicker, goods are heavier, and cost is higher.
The development space of pallet industry is very huge, and because the planform of combined wood-plastic pallet is thicker large, cost is higher, cannot replace Wooden tray completely always, and therefore, the planform of researching and developing new combined wood-plastic pallet each several part is imperative.
Summary of the invention
Technical matters to be solved by this invention is, overcomes the shortcoming of prior art, proposes a kind of combined wood-plastic Pallet longitudinal beam, have that wall is thin, muscle is many, the rational feature of framed structure, be specially adapted to squeeze the feature of technique, and following process is simple and convenient, the specification of product, yield rate is high.
In order to solve above technical matters, the invention provides a kind of combined wood-plastic Pallet longitudinal beam, comprise upper strata beam and lower floor's beam, described lower floor distance between girders is arranged on the bottom of described upper strata beam, between each lower floor beam, forms arch forklift hole; Described upper strata beam and lower floor's beam are all mainly by upper plate, lower shoe be arranged on the main wall in centre between upper and lower bottom plate and perpendicular muscle forms elongated structure and forms, the perpendicular muscle of described upper strata beam and the perpendicular muscle of lower floor's beam arrange along the elongated direction interval of described elongated structure, and vertical with the axis of the elongated direction of described elongated structure, the main wall in centre of described upper strata beam and the main wall in centre of lower floor's beam are provided with at least one along the elongated direction of described elongated structure respectively, and with corresponding upper strata beam or lower floor's beam square crossing; On the main wall in centre of described upper strata beam, be at least provided with two cylinders, described cylinder is placed between adjacent described perpendicular muscle, and described cylinder is provided with the through hole running through up and down.
The present invention further limits technical scheme: aforesaid combined wood-plastic Pallet longitudinal beam, described perpendicular muscle is I-shape construction, the upper and lower dull and stereotyped vertical plate of its upper flat plate having, lower flat board and connection is vertical with upper plate, lower shoe and the elongated azimuth axis of elongated structure respectively, the vertical plate square crossing of the perpendicular muscle of the main wall in described centre and I-shape.
Aforesaid combined wood-plastic Pallet longitudinal beam, the main wall in described centre is arranged in the elongated azimuth axis of described elongated structure.
Aforesaid combined wood-plastic Pallet longitudinal beam, is interval with 6～16 cylinders on the main wall in centre of described upper strata beam, is interval with 3～9 cylinders on described lower floor beam.
Aforesaid combined wood-plastic Pallet longitudinal beam, described in the through-hole aperture that runs through be φ 10～φ 18, the directly pre-buried mold insert being connected with top bed board and end bed board.
Aforesaid combined wood-plastic Pallet longitudinal beam, for strengthening the intensity of longeron, and reduces the weight of longeron, and described perpendicular muscle is I-shape construction.
Aforesaid combined wood-plastic Pallet longitudinal beam, described forklift hole spacing equates, when improving fork truck and inserting and holder stressed homogeneity when thing.
Further, aforesaid combined wood-plastic Pallet longitudinal beam, in the upper strata beam of described forklift hole top, between adjacent perpendicular muscle, be provided with reinforced rib, described reinforced rib is herringbone muscle, diagonal bar, annulus muscle, cross bar or rhombus muscle, to increase the rigidity of Pallet longitudinal beam, in the time of forklift lifting, upper strata Liang Neng gives enough bearing forces.
The invention has the beneficial effects as follows: the present invention has, wall is thin, and muscle is thin, rational in infrastructure, and product anti-impact, bending resistance, shear strength are high, and product density is high; Weight reducing 50% left and right in the situation that ensuring the quality of products, reduces the material cost of raw material greatly, and required form one-shot forming simultaneously does not need secondary processing greatly to reduce labour cost, is applicable to replacing H-girder and the Wang Ziliang of combined wood-plastic pallet.
