Description

a plastic greenhouse

technical field

The utility model relates to a plastic greenhouse for planting vegetables, fruits, flowers and the like. More specifically, the utility model relates to a traction-type plastic greenhouse. The traction type plastic greenhouse uses less material, has simple manufacturing process, wide application range, convenient maintenance and low cost.

Background technique

As shown in Figure 1, the existing plastic greenhouse is generally made by covering the light-transmitting plastic film on the arch frame. The arch frame includes a plurality of arch rods 1, and the arch rods are made of various materials, such as elastic wooden strips, bamboo strips, steel pipes, angle steel and the like. There are multiple arch rods, and the corresponding arch rods are connected by a central joint 2 to form an arch frame. Each arch is fixed separately, and the top and side of the arch are respectively connected with the central longitudinal tie rod 3 and the side tie rod 4 to make the arch firm. In order to make the arch further firm, a central support 5 is also arranged on the central top of the arch. Generally, the distance between each arch rod is not greater than 800mm, typically 60mm-80mm. Due to the use of multiple arches with short intervals in the plastic greenhouse, not only the manufacturing cost is high, the manufacturing process is cumbersome, and the maintenance is inconvenient, but also the existence of too many arches affects daylighting and reduces the performance of the plastic greenhouse.

Contents of the invention

The purpose of the utility model is to provide a new type of plastic greenhouse, which overcomes the defects of the existing plastic greenhouse, reduces the manufacturing cost of the plastic greenhouse, simplifies the manufacturing process, facilitates maintenance, has wide applicability and has better lighting and heat preservation performance.

The purpose of this utility model is achieved in the following way: a steel frame plastic greenhouse, including an arch frame and a traction cable, is characterized in that: said arch frame at least includes two augmented roof frames fixed at both ends of the greenhouse, along the A plurality of traction cables are fixed on the arched surface of the arch in the longitudinal direction, and the traction cables are fixed on the arch.

In a specific embodiment, the reinforced scaffolding includes two arches, and a plurality of cross braces and beams are used for reinforcing and fixing between the two arches.

In yet another specific embodiment, the reinforced scaffolding includes an arch and a brace connected to the arch.

Since the utility model changes the traditional plastic greenhouse from a vertical design to a longitudinal pulling design, a plurality of elastic traction cables are used to pull at least two reinforced roof frames located at both ends of the greenhouse, which not only greatly reduces the use of arch rods The number can also effectively support the plastic film, thus compared with the existing plastic greenhouses, not only greatly reduces the production cost, simplifies the manufacturing process, but also the utility model is very convenient for maintenance and replacement. At the same time, the use of fewer arch rods for support can enhance the effect of lighting and heat preservation, and further improve the performance of the plastic greenhouse.

Detailed ways

As a situation of the utility model, Fig. 2 shows a kind of plastic greenhouse. The greenhouse includes two fixed reinforced roof frames 2 at both ends, and the reinforced roof frame 2 includes two arches, and a plurality of cross braces and beams 4 are used for additional force between the two arches. fixed. The arch frame adopts the existing technology in the field to be bent according to needs, and the material used can be angle steel, steel pipe or similar materials. The fixing of the reinforced scaffolding 2 can also be carried out by adopting the prior art in this field. As a situation of the present utility model, the augmented roof frame 2 adopts concrete prefabrication to fix 1 . As an option, three-way cable-staying or other methods can also be used to fix the augmented roof frame 2 in the utility model.

The above-mentioned plastic greenhouse also includes a plurality of pulling cables 3 fixed on the arched surface along the longitudinal direction of the arch, and the pulling cables 3 are fixed on the inner arch of the reinforced scaffolding 2 . The pulling rope 3 is generally made of elastic material, typically hot-dip galvanized low-carbon steel wire. The arrangement of the traction cables 3 can be determined according to the width of the greenhouse, and the distance between the respective traction cables 3 can be changed, as long as the plastic film covered thereon can be balanced and evenly supported. As an option, the greenhouse further includes at least one common scaffold 6 located between the reinforced scaffolds 2 .

Fixing the traction rope 3 on the reinforced scaffolding 2 and the common scaffolding 6 can be carried out by using the prior art in this field. As a situation of the present utility model, the butterfly wings can be welded on the scaffold, and the predetermined positions of the butterfly wings have been perforated, and then the traction rope 3 is fixed through the perforations. It is also possible to weld a circular ring at a predetermined position of the scaffold according to the outer dimensions of the traction cable 3, so that the traction cable 3 is fixed through the circular ring. It is also possible to carve a groove at a predetermined position of the scaffold, so that the pulling rope 3 is fixed through the groove.

The arches of the common scaffolding 6 may have the same size and/or material as the arches of the above-mentioned reinforced scaffolding 2, or may be different. The distance between them can be determined according to the needs. Because the utility model adopts the traction design, the distance between the arches can be much larger than the distance between the arches of the existing greenhouses, generally 2-15 meters, preferably 5-12 meters, the ideal situation is 8-10 meters. Preferably, the arch frame located in the center of the greenhouse can be fixed as a central frame to further improve the firmness of the greenhouse. Alternatively, the fixing method may be prefabricated concrete fixing.

As yet another aspect of the utility model, Fig. 3 shows yet another plastic greenhouse. The structure of the plastic greenhouse is different from that of the above-mentioned greenhouse reinforced scaffolding 2, and other structures and/or arrangements can be the same as the above-mentioned greenhouse. As shown in FIG. 3 , the reinforced scaffolding 2 includes an arch and a brace 7 fixedly connected to the arch. The brace 7 can be fixedly connected to the arch frame by welding or other connection methods known in the art, and then the connected reinforced scaffolding 2 can be prefabricated with concrete or fixed by a method known in the art. Other fixing methods are used for fixing.

Based on the description of the preferred embodiments of the present invention, it should be clear that the present invention defined by the appended claims is not limited to the specific details set forth in the description above, and there are many aspects of the present invention that do not depart from the spirit or scope of the present invention. Obvious possible modifications can likewise achieve the object of the invention.
