Abstract
The utility model discloses a steel hollow plate for a plastic hothouse which belongs to the field of planting technology in agriculture. One end of the cross section of the plate is provided with a convex edge, and the other end is provided with a recess; the convex edge of the plate can be inserted into the recessof another plate. The plate made from transparent plastic makes a common plastic film and a frame combine into a whole. The light transmittance of the plate is higher than the light transmittance of an existing plastic film; the service life of the agricultural hothouse assembled by the plate is lengthened out to seven long years without maintenance.
Description
The utility model relates to a kind of rigidity plastics booth hollow sheet material that belongs to the agricultural planting technique field.
At present, the agricultural planting green house of vegetables is essentially skeleton covered with plastic film structure, and the shortcoming of this structure maximum is that plastic foil is fragile, about about 1 year of life-span.And skeleton only plays the plastic film effect of supporting, to the transparent heat insulating function of booth without any contribution.The plastic film manufactured materials that uses at present is polypropylene in addition, and its light transmission is undesirable.No matter greenhouse or agricultural greenhouse, selection, design and structure all must be followed abundant reception solar irradiation and accumulate this principle of solar thermal energy to greatest extent.
The purpose of this utility model is exactly to provide a kind of photic zone of greenhouse or agricultural planting booth and transparent rigidity plastics booth hollow sheet material that skeleton unites two into one of making for solving disadvantages of background technology.
The purpose of this utility model is achieved in that an end in the cross section of this sheet material is provided with the convex edge, and the other end is provided with groove, and convex edge section and groove section adapt, and the centre in the cross section of sheet material is provided with cavity.This sheet material is that transparent plastic is made, and the groove of another piece sheet material can be inserted in the convex edge of sheet material.
The utility model is compared background technology and is had following advantage: 1, have good rigidity behind the board material splice, thereby save the skeleton of greenhouse or booth; 2, sheet material reaches 7 years service life, and user's cost of use is extremely low; 3, the sheet material light transmittance of transparent plastic making is very high, has improved the temperature and the photosynthesis of greenhouse or booth.
Fig. 1 analyses and observe shaft side figure for the utility model.
Fig. 2 uses scheme of installation for the utility model.
The utility model is further described by embodiment below in conjunction with accompanying drawing: as shown in Figure 1, the left end in sheet material 1 cross section is provided with a convex edge 2, and right-hand member is provided with a groove 3, and the centre in sheet material 1 cross section is provided with cavity 4.The convex edge 2 of a sheet material 1 is inserted in the groove 3 of another sheet materials and is stitched together.Convex edge 2 and groove 3 also can be designed to wedge shape, so that make splicing more firm.As shown in Figure 2, as assembly wood flooring, assembly unit all-in-one-piece clear sheet 1 overarches, and downside and ground are fixed, and upside is fixed with the back wall, and both sides and side wall are fixed, thereby have save common skeleton structure.Because the head of plant growing only: condition, also is the main source of greenhouse or booth heat energy.The raising of greenhouse or booth temperature inside can promote photosynthesis of plants.As the heat insulation and transmission material, to be that higher transparency is arranged between 4000-7000A in the photochemical activity radiation scope not only, guaranteeing photosynthetic carrying out, and be that very high transparency is arranged between 7000-25000A, to obtain more solar thermal energy at the infrared region of solar spectrum.Plastic film polypropylene manufacturing commonly used, its light transmittance is about 60-80%, and the utility model is made with polyvinyl chloride (PVC), and its light transmittance is about 80-100%, is better than traditional polyacrylic film greatly.
