Abstract
A greenhouse forcing-frame without film-pressing line comprises a greenhouse forcing-frame 1 and a plastic film 2. The utility model is characterized in that the section shape of a film-pressing groove 3 is a rectangular groove with two side rims rolled inwards, the film-pressing groove 3 is fixed at a position of stiffeners of the greenhouse forcing-frame 1, a snap spring 4 is arranged inside the film-pressing groove for clamping the film 2 in the rolled rims of the film-pressing groove 3. No friction or contact is caused between the film and the forcing-frame, a film-pressing line is not required, and under the protection of the film, the steel forcing-frame is prevented from being rusted, thereby guaranteeing a longer service life of the whole greenhouse. The film-pressing groove 3 of the design can be used independently when a short distance greenhouse forcing-frame is made, the film-pressing groove 3 and the stiffeners are welded together to be directly used as a the forcing-frame, or the film-pressing groove 3 can be fixed on the forcing-frame 1 which is provided with stiffeners and strip materials. The utility model has a firm structure, saves materials, and saves cost of labors and materials for frequently changing films.
Description
Affiliated technical field the utility model relates to the agricultural tillage facility, a kind of without film-pressing line big-canopy framework.
The existing agricultural of background technology with big-canopy framework have fiberglass, steelframe, bamboo, yoke or the like.General installation method all be big-canopy framework is fixed after, plastic foil is covered on the skeleton, again with hawser or, steel wires etc. are made film-pressing line plastic foil are fixed on the skeleton, have so just finished the booth sealing.The shortcoming of this mode fixed plastics film is: when the film-pressing line tension, because external wind acts on film-pressing line and the plastic foil contact site makes the breakage of film large tracts of land easily; When film-pressing line was crossed pine, then the wind loading rating of booth descended, the easier breakage of plastic foil.
The summary of the invention the purpose of this utility model provides a kind of without film-pressing line big-canopy framework.
The without film-pressing line big-canopy framework, comprise big-canopy framework 1, plastic foil 2, it is characterized in that film-pressing tank 3 cross sectional shapes are the rectangular recess of bilateral edge curls inward, film-pressing tank 3 is welded together with the reinforcement 5 on the big-canopy framework 1, jump ring 4 is arranged in the film-pressing tank 3, be used for film 2 is stuck in the volume edge of film-pressing tank 3.
This without film-pressing line big-canopy framework makes between film 2 and the frame 1 without film-pressing line, does not have the friction contact, and makes steel skeleton 1 be in the protection of film 2, makes the steelframe non-corroding, thereby guarantees that whole booth longer service life is of a specified duration.This is firm in structure, material-saving, save the worker that often changes film, material money.
Fig. 1 is the without film-pressing line big-canopy framework cross-sectional view of user mode;
Fig. 2 is jump ring 4 shape schematic diagrames;
Fig. 3 compresses into film 2 for jump ring 4 longitudinal sectional drawing of groove 3;
Fig. 4 is that groove 3 combines schematic diagram with skeleton 1;
Embodiment without film-pressing line big-canopy framework comprises big-canopy framework 1, plastic foil 2, sees Fig. 1, it is characterized in that film-pressing tank 3 cross sectional shapes are the rectangular recess of bilateral edge curls inward, and film-pressing tank 3 is fixed on the big-canopy framework 1; See Fig. 4, jump ring 4 arranged in the film-pressing tank 3, be used for film 2 is opened up in the groove along groove 3 upper edges, the volume of above, the film 2 suitable for reading from groove film 2 being clamp-oned and is stuck in film-pressing tank 3 by jump ring 4 along in.
The jump ring 4 positive and negative trapezoidal wire for extending and joining is seen Fig. 2, and trapezoidal height equals film-pressing tank 3 inner groovy width, sees Fig. 3, as the steel wire diameter of jump ring 4 less than curls inward along width.
The design's film-pressing tank 3 can use separately when making short-range frame or film-pressing tank 3 and reinforcement 5 is welded together, directly uses as skeleton 1, film-pressing tank 3 can also be fixed on the skeleton 1 of existing reinforcement and web formation.
