Abstract

The utility model discloses a wood-plastic greenhouse framework which is formed by splicing of multiple rows of greenhouse frameworks. Each greenhouse framework is formed by splicing of multiple longitudinally distributed single greenhouse frameworks. Each single greenhouse framework comprises two stand columns, a lagging jack and multiple connecting pieces, wherein the two ends of the lagging jack are connected with the upper ends of the two stand columns through the connecting pieces respectively. Lateral beams are fixed to the inner side of each row of greenhouse frameworks. The inner side and outer side of each stand column and the inner side and outer side of each lagging jack are respectively provided with a first groove and a press rod, and a film on the wood-plastic greenhouse framework is fixed to the inner side and outer side of the wood-plastic greenhouse framework by pressing the press rods into the first grooves. A greenhouse adopting the wood-plastic greenhouse framework is good in heat insulation effect.

Description

A kind of wood is moulded big-canopy framework

Technical field

The utility model relates to agricultural booth frame, is specifically related to a kind of wood and moulds big-canopy framework.

Background technology

In traditional booth, support generally adopts wood or bamboo to make, wood or bamboo are whittled into flat, fining away to insert in soil and form arc frame in two, arc frame side by side of multiple intervals and cross bar is linked together and formed greenhouse bracket with iron wire, though this booth cost is low, installation fee is high, stability is poor, and service life is short, can not reuse; In addition, the greenhouse bracket of producing with steel, the middle column that is provided with in booth, the cross bar on both sides is fixed on column, and vertical pole connects cross-arm by multiple connectors and form support on side crossbeam arranged side by side, and defect is that booth material is more, bracket assembled inconvenience, cost is also high.Also the use plastic tunnel having, plastic tunnel all adopts steel skeleton or does supporting with concrete column and make plastic tunnel, and skeleton weight is large, fragile, is difficult for transport, and obviously its cost is higher.And booth generally adopts monofilm now, heat insulation effect is not good, and some crops do not reach demand.

Utility model content

The purpose of this utility model is to overcome the shortcoming of above-mentioned prior art, provides a kind of Simple wood to mould big-canopy framework, adopts the high insulating effect of the booth of skeleton.

For achieving the above object, wood described in the utility model is moulded big-canopy framework and is spliced by some row big-canopy frameworks, single canopy skeleton that every row big-canopy framework is longitudinally distributed by several is spliced, each single canopy skeleton includes two root posts, a bow member and some connectors, the two ends of bow member are connected by connector with the upper end of two columns respectively, the inner side of every row big-canopy framework is all fixed with side crossbeam, in same row big-canopy framework, between each single canopy skeleton, is connected by side crossbeam;

The inside and outside both sides of described column and the inside and outside both sides of bow member are equipped with the first groove and the depression bar for fixed film.

The both sides, front and back of described column and the both sides, front and back of bow member are equipped with the second groove, are equipped with the first through hole on column and bow member.

Corresponding column and bow member that column in described any row big-canopy framework and bow member are adjacent respectively in row big-canopy framework are connected by connector and bolt.

The span of described single canopy skeleton is 3m.

The cross section of described connector is " L " type structure.

Described big-canopy framework is made by Wood-plastic material.

The utlity model has following beneficial effect:

Wood described in the utility model is moulded big-canopy framework and is spliced by some row big-canopy frameworks, single canopy skeleton that every row big-canopy framework is longitudinally distributed by several is spliced, each single canopy skeleton includes two root posts, a bow member and several connectors, the inside and outside both sides of column and the inside and outside both sides of bow member are equipped with the first groove and depression bar, by being pressed into, depression bar in the first groove, make wood mould the inside and outside both sides that film on big-canopy framework is fixed on wood and moulds big-canopy framework, thereby come, for booth thermal insulation, to effectively raise the heat insulation effect of booth by bilayer film.

Embodiment

Below in conjunction with accompanying drawing, the utility model is described in further detail:

With reference to figure 1, Fig. 2, Fig. 3, Fig. 4 and Fig. 5, wood described in the utility model is moulded big-canopy framework and is spliced by some row big-canopy frameworks, and single canopy skeleton that every row big-canopy framework is longitudinally distributed by several is spliced, and the span of single canopy skeleton is 3m.Each single canopy skeleton includes two root posts 2, bow member 1 and some connectors 3, the two ends of bow member 1 are connected by connector 3 with the upper end of two columns 2 respectively, the inner side of every row big-canopy framework is all fixed with side crossbeam 4, in same row big-canopy framework, between each single canopy skeleton, is connected by side crossbeam 4; The cross section of connector 3 is " L " type structure.

The inside and outside both sides of described column 2 and the inside and outside both sides of bow member 1 are equipped with the first groove and depression bar, make wood mould the inside and outside both sides that film on big-canopy framework is fixed on wood and moulds big-canopy framework by depression bar is pressed in the first groove.The both sides, front and back of column 2 and the both sides, front and back of bow member 1 are equipped with the second groove, on column 2 and bow member 1, are equipped with the first through hole.Corresponding column 2 and bow member 1 that column 2 in any row big-canopy framework and bow member 1 are adjacent respectively in row big-canopy framework are connected by connector 3 and bolt.Big-canopy framework is made by Wood-plastic material.

It should be noted that, the two ends up and down of connector 3 are equipped with the second through hole, any one column 2 is equipped with two row third through-holes with the junction of bow member 1 or other columns 2, and bolt is fixedly connected with column 2 through the third through-hole on described column 2 and second through hole of connector 3 one end with one end of connector 3; The junction of the two ends of any one bow member 1 and column 2 is equipped with two row fourth holes, and bolt is fixedly connected with one end of connector 3 through the fourth hole on described bow member 1 and second through hole of connector 3 one end with bow member 1.

Assemble method of the present utility model is: utilize connector 3 bow member 1 two ends and column 2 use bolted, be built into so single canopy skeleton of 3 meters of spans, then two inner sides of all single canopy skeletons in same row big-canopy framework are connected by two side crossbeams 4 respectively, simultaneously can splice as required multiple row big-canopy framework, column 2 and bow member 1 that wherein in every row big-canopy framework, the column 2 of single canopy skeleton and bow member 1 are adjacent single canopy skeleton in row big-canopy framework are connected by connector 3.Then nuzzled in soil in the lower end of column 2, if local wind-force is bigger than normal, in actual installation process, connector 3 can be risen to and be applicable to the convenient position of installing of common people's height, so not only make easy for installation, and can improve the wind load resistance ability of booth entirety, after described wood is moulded big-canopy framework and installed, then by the inside and outside both sides that film is routed to wood and moulds big-canopy framework, then depression bar is pressed into wood and moulds in the first groove of both sides inside and outside big-canopy framework.Shape and structure that wood in the utility model is moulded connector 3, bow member 1 and column 2 in big-canopy framework are identical, facilitate user installation and dismounting, and can be according to the demand of crops, set up the wood of different spans and mould big-canopy framework.
