Abstract

The utility model relates to a plastic greenhouse skeleton, comprising a plurality of transversely arranged arch bars and a plurality of tensioned strings which are respectively and crossedly fixed on each of the arch bars. The utility model is characterized in that the plastic greenhouse skeleton comprises transverse tension string, a tensioner and a steel wire clamp, wherein, the tensioner is arranged on the center of each tensioned string; each crosspoint of adjacent tensioned strings is fixed through the steel wire clamp; the transverse tension string which passes through the steel wire clamp on the crosspoint in a position corresponding to each arch bar is fixed with the steel wire clamp. The utility model which has the advantages of simple structure, high stability, even stress and strong carrying capacity can be widely used in various crop greenhouses.

Description

Big plastic hot-shed with it

The utility model relates to a kind of skeleton of farm plastic greenhouse.

In the prior art, big plastic hot-shed with it generally adopts double-deck arch bar, and connecting reinforcement forms an independent skeleton between double-deck arch bar, and couples together with reinforcing bar and big jig between each independent skeleton, forms the booth of an integral body.Said structure steel using amount on the whole is bigger, and weight is big, the cost height.In order to address the above problem, have a kind of structure to adopt following design: it is the arch bar bottom opening that is with plastic sheath outside, and with the tensioning string two ends hook that band colludes, one one is inserted in the perforate alternately.And there is following problem in this structure: 1, in the arch bar bottom opening, both made plastic sheath protection, also can other enter perforate owing to water vapour etc., and cause arch bar and the corrosion of tensioning string.2, the pulling force of tensioning string is non-adjustable, and the firmly good inadequately of back string is installed.

At the problems referred to above, the purpose of this utility model provides a kind of in light weight, bearing capacity is high, cost is low big plastic hot-shed with it.

For achieving the above object, the utility model is taked following design: a kind of big plastic hot-shed with it, it comprises some transversely arranged arch bars and the staggered some tensioning strings that are fixed on each root arch bar, it is characterized in that: it comprises laterally draws string, stretcher and steel wire card, described stretcher is arranged on the central authorities of each described tensioning string, the crosspoint of the described tensioning string that each is adjacent is fixed by described wire clamping, the described described steel wire card that laterally draws on the described crosspoint that string passes each described arch bar opposite position, and fixing with it.

Described arch bar adopts thin-wall steel tube, described tensioning string and laterally draw string employing steel wire.

The fixedly employing welding of described tensioning string and described arch bar.

At the described arch bar that fixes, tensioning string, laterally draw on string, stretcher and the steel wire card and scribble the iron red alcohol acid anti-corrosive primer, and on described iron red alcohol acid anti-corrosive primer, scribble the chlorinated rubber exterior trim paint.

The utility model is owing to take above design, and it has the following advantages: 1, the utility model laterally draws string owing to being provided with between described each arch bar, can reduce rolled steel dosage more effectively, alleviate overall weight, and cost is low.2, therefore the utility model makes the shape of arch bar adjustable owing to the central authorities at each tensioning string are provided with a stretcher, and tensile force is adjustable, and makes arch bar be subjected to prestressing force, and like this, stressed even, bearing capacity increases, overall structure weight saving.3, the utility model is owing to fix a steel wire card in the crosspoint of each adjacent tensioning string, especially will laterally draw string to pass steel wire card on each arch bar opposite position crosspoint and fixing, thereby make whole skeleton form numerous triangle, this triangular structure is stressed good especially, and very stable.4, the utility model is owing to adopt the tensioning string is welded on connected mode on the arch bar, therefore, overcome the easy problem that produces corrosion of arch bar punching connection in the prior art, especially the utility model adopts special iron red alcohol acid anti-corrosive primer, and be coated with the chlorinated rubber exterior trim paint thereon, can make the utility model easy construction, good antirust property, cost is low.

Below in conjunction with accompanying drawing the utility model is described in detail.

Fig. 1 is the utility model structural representation

Fig. 2 is the schematic diagram that is provided with that the utility model laterally draws string

Fig. 3 is the utility model steel wire card structure schematic diagram

As Fig. 1, Fig. 2, shown in Figure 3, the utility model comprises some transversely arranged arch bars 1 with the thin-wall steel tube making, on each arch bar 1, be welded with to interleaved the tensioning string 2 that some 6mm steel wires are made, the stretcher 3 of a M8 is set in the central authorities of each tensioning string 2.One steel wire card 4 is set on the crosspoint of each adjacent tensioning string 2, and in the steel wire card 4 on each arch bar 1 on the opposite position, what wear laterally that a 5mm steel wire makes laterally draws string 5.Like this, just 1 of each arch bar can be linked to be an integral network structure with some strings 5 that laterally draw, simultaneously tensioning string 2 with laterally draw string 5 being connected by steel wire card 4, form many firm triangular structures, make that the utility model is simple in structure, good stability, stressed evenly, and bearing capacity is strong.After whole big-canopy framework installs, can on skeleton, apply commercially available extraordinary iron oxide red alcohol acid rust-inhibiting primer, and apply the chlorinated rubber exterior trim paint thereon.

In the foregoing description, arch bar 1 also can be taked other structure, tensioning string 2 and laterally draw the diameter of string 5 also can change.Stretcher 3 and steel wire card 4 all can be taked commercially available standard component, and the rush-resisting material of coating can also adopt other material, also can use plastic technology.Tensioning string 2 is connected with arch bar 1, also can take alternate manner except that welding.
