Abstract

The utility model relates to a combined plastic-steel double-film greenhouse framework for covering a plastic greenhouse. The greenhouse framework is formed by that two straight arched single frameworks are inserted and connected with the both sides of a T-shaped framework connector; a pipe strut with fixed screw holes is inserted and connected in the jack of the framework connector, and the lower part of the pipe strut is inserted and connected with an inverted T-shaped strut base; two triangular grooves are symmetrically arranged on both sides of a reinforced tape on a downward suspending cylinder of each of the single frameworks; inner film fasteners are connected with the single frameworks, and an inner layer plastic film is fixed to the greenhouse framework. The combined plastic-steel double-film greenhouse framework of the utility model adopts the combination of steel pipes and plastics, so the greenhouse framework has corrosion resistance and compression resistance, and the manufacturing cost is only half of that of welding concrete irons and pulling net; the combined structure is beneficial for assembly and disassembly, time saving and labor saving; the covering double-layer plastic film which is the reformation of cool greenhouse displaces the traditional warm keeping methods by using grass curtains or cotton curtains, and has good warm keeping property and convenient management without the trouble of coiling the curtains and dropping the curtains.

Description

Combined type plastic-steel double film booth skeleton

Technical field: the utility model relates to, be used for protection ground, rural area fruits and vegetables off-season cultivation, a kind of combined type plastic-steel double film booth skeleton that the fastener booth is used.

Background technology: the anti-season cultivation on protection ground, not only have tempting economic benefit and fine development prospect, also satisfied the material requisite of people's lives simultaneously.The development of booth industry will be accelerated the paces that the rural area industrialization is got rich.Traditional big-canopy framework is that rod supports with the binding of bamboo base, and not only the width of booth is limited to, and meets driving snow weather, tends to be scraped, compressive strain, even collapses; Influence the daylighting and the operation of booth again because of pillar is intensive, service life is short.For overcoming the deficiency of traditional bamboo wooden frame, people draw in the net to weld the system skeleton with reinforcing bar again, and this skeleton cost input is bigger, and the effort of taking a lot of work is not corrosion-resistant, is difficult for transportation, and amorphous products booth specification is lack of standardization again.More than two kinds of skeletons all be the monofilm cold canopy framework, what night heating was leaned on is to cover straw screen or mat or cotton curtain or light a fire the management trouble.

Summary of the invention: reinforcing bar draws in the net to weld cost height, the effort, perishable of taking a lot of work that the system skeleton exists in the prior art in order to solve, many disadvantages such as trouble are managed in the heating at night lack of standardization and the monofilm cold canopy framework of amorphous products booth specification, and the utility model provides a kind of combined type plastic-steel double film booth skeleton.The design of this combined type plastic-steel double film booth skeleton is, with two be straight arc be plugged on the both sides of a T type skeleton connector by last outstanding cylinder and the monomer skeleton that down is connected shaping by reinforce belt between outstanding cylinder, in the jack of the vertical cylinder lower end of the T of skeleton connector type, the pipe pole of pegging graft and having fixing threaded hole, the pole base of the below of pipe pole and ⊥ type is pegged graft, whole big-canopy framework is propped, for the fixing needs of inner plastic film, reinforce belt bilateral symmetry on the following outstanding cylinder of monomer skeleton has the twice triangular groove, resilient, the inner membrance buckle that annulus opening two ends have the triangle plush copper that is complementary with triangular groove is connected with the monomer skeleton, with firm being fixed on the big-canopy framework of inner plastic film.Combined type plastic-steel double film booth skeleton of the present utility model adopts steel pipe and plastics to be composited, and compared with the prior art corrosion-resistant, compressive resistance is strong, and cost is low, and cost is half of steel weldering system; Knockdown structure helps the industrialization that the batch machining of big-canopy framework is produced, and assembling, convenient disassembly save labor, and can make different width such as 6 meters, 8 meters, 10 meters; The most outstanding is, can cover double-layer plastic film, is once to reform and innovate for cold canopy, and it has replaced the traditional straw screen or mat or the thermal-insulating method of cotton curtain, good heat insulating, and convenient management, many troubles of having saved roller shutter, having put curtain.The exploitation of this big-canopy framework will drive the fast development of China's greenhouse gardening industry, and friend provides convenience for vast farmers.

Description of drawings: Fig. 1, be the structural representation of combined type plastic-steel double film booth skeleton of the present utility model.Fig. 2, be the structural representation of monomer skeleton 1 among Fig. 1.Fig. 3, be the schematic cross-section of the monomer skeleton 1 among Fig. 2.Fig. 4, be the structural representation of skeleton connector 4 among Fig. 1.Fig. 5, be the schematic diagram of pipe pole 6 among Fig. 1.Fig. 6, be to sit 8 structural representation at the bottom of the pole among Fig. 1.Fig. 7, be the structural representation of the inner membrance buckle 9 among Fig. 1.

Embodiment: for the structure to combined type plastic-steel double film booth skeleton of the present utility model has further understanding, details are as follows in conjunction with enforcement of the present utility model:

Embodiment, combined type plastic-steel double film booth skeleton.

With reference to accompanying drawing 1,2,3,4,5,6,7, the structure of combined type plastic-steel double film booth skeleton of the present utility model includes among the figure two and is straight arc, by last outstanding cylinder and the middle monomer skeleton 1 that is connected moulding by reinforce belt of down outstanding cylinder, the both sides of reinforce belt on the following outstanding cylinder of monomer skeleton 1, the leg-of-mutton groove 2 of the twice that symmetry has, the T type of pegging graft with two monomer skeletons 1, the skeleton connector 4 of the jack 3 that the vertical cylinder lower end has, be plugged on skeleton connector 4 belows on, the pipe pole 6 that has fixing threaded hole 5 down, at the bottom of the pole of pegging graft below the pipe pole 6 that is the ⊥ type that has center hub 7, sit 8, with be connected with monomer skeleton 1 flexible, the annulus openend has the inner membrance buckle 9 of the triangle plush copper that is complementary with triangular groove 2, reaches the horizontal stroke at skeleton connector 4, the reinforcement 10 that vertical cylinder junction is provided with is formed.All be provided with steel pipe in the outstanding cylinder with in the pipe pole 6 on monomer skeleton 1, the outer compound one deck plastics of pipe become one by extrusion molding.The horizontal cylinder two ends declivity of skeleton connector 4, the diameter of its gradient and cylinder are to be complementary with the outstanding cylindrical interior pipe of going up of monomer skeleton 1.All having fixing threaded hole 5 on the seat 8 at the bottom of monomer skeleton 1, skeleton connector 4, pipe pole 6 and the pole, after pegging graft between part and the part, it is being reinforced with bolt.

During use, after individual parts in the assembly are connected and fixed, formed the whole skeleton of plastic tunnel, outside whole skeleton, plastic film on the cover, adventitia for booth, in whole diaphysis, the inner plastic film is drawn, be connected with the leg-of-mutton groove 2 on the following outstanding cylinder on inner membrance buckle 9 and the monomer skeleton 1 then, the inner plastic film also has been fixed on the whole skeleton, so just formed the booth that has double-plastic, leave air layer between double-layer films, heat insulation effect is very good.
