Description

Green house profile structure securing member

The utility model relates to agricultural greenhouse booth profile structure securing member.

Existing more new-type green house adopts solid membranous type material, this profile structure optimization all has continuously film groove and reinforcement admittedly on the every arch bar, make structural strength big, but, give and cause difficulty and inconvenience when adopting this section bar to make booth owing to lack effective connection securing member.

The purpose of this utility model provides a kind of securing member that is fit to this solid membranous type material, makes when adopting this section bar to manufacture booth not only firmly but also convenient.

Scheme of the present utility model is, agricultural booth frame is made up of arch bar, pull bar, canopy head and door, and whole booth is by connected component, T type screw, a word join card, T type connection slot and card pad form three kinds of connecting modes, canopy is connected in aggregates, form framework, three kinds of connections are:

A) cross connects, convex join card, the Superjacent sectional material of screens right-angled intersection section bar; Pass the fluting of top section bar tightens with nut with T type screw;

B) the T type connects, and the lower profile of the section bar that T type join card is vertical with the T type is blocked and by T type bolt, aided the border areas for two of T type join card and by T type bolt upper profile is fixed;

C) flat recess connects, and two section bar levels are joined, and flat recess is interspersed in two section bars by the card pad, and T type bolt is affixed with flat recess, card pad, section bar.

Further specify below in conjunction with accompanying drawing.

Fig. 1 connects for flat recess;

Fig. 2 connects for the T type,

Fig. 3 connects for cross.

Wherein, 1-section bar, 2-flat recess, 3-T type screw, 4-card pad, 5-T type join card, 6-convex join card.

With reference to Fig. 1, Fig. 2, Fig. 3 adopts connected component of the present utility model, can realize three kinds of connecting modes, has solved the articulation issues of section bar when building booth, and all interfaces all design in booth, has kept the smooth of cover film face.
