Abstract

The utility model belongs to an improved agricultural plastic-covered greenhouse arched beam structure, and particularly relates to a double-film arched beam device for an agricultural sunlight greenhouse. The double-film arched beam device comprises an upper arched beam and a lower arched beam which are made of light material; raised longitudinal ribs are arranged on the top surface of the lower arched beam; longitudinal grooves matched with the raised longitudinal ribs on the lower arched beam are formed on the upper arched beam; and a plastic-covered greenhouse film is fixedly connected between the upper arched beam and the lower arched beam, and is also fixedly connected on the top surface of the upper arched beam in a covered way. Besides, the cross sections of the raised longitudinal ribs on the lower arched beam are rectangular or trapezoidal. The utility model has the advantages that firstly, the thermal utilization efficiency is greatly improved; secondly, the structure is novel, the material is light, the deadweight is strong, and the assembly and the disassembly are easy; and thirdly, the double-film arched beam device is energy-saving, economical and environment-friendly, has great significance of the environment-friendly society constructed in China, and can generate greater social and economic benefits.

Description

A kind of two film arched girder devices of agricultural sun light green house
(1) technical field
The utility model belongs to two film arched girder devices of the improvement of agricultural greenhouse shed arched girder structure, particularly a kind of agricultural sun light green house.
(2) background technology
At present, northern area uses the arched girder majority of agricultural booth to play the effect of a booth framework winter, and the arched girder material mostly is wooden, bamboo matter or steel material etc., and its bearing is not satisfactory, and harsh weather such as strong wind or heavy snow are easily with its damage.Simultaneously, the user need be layered on other insulation material and carry out the warming of booth on the booth framework, and warming effect is not very desirable, the heating of therefore must lighting a fire in the winter time, the necessary preference temperature so that the interior agricultural product of assurance booth grow.Heating just must be used the energy because light a fire, and what the northern area majority used is coal resource.This not only pollutes to surrounding environment, uses coal to light a fire simultaneously and warm oneself also can have many potential safety hazards and increase Financial cost.
(3) summary of the invention
It is a kind of novel that the purpose of this utility model is to provide, material is lighter, two film arched girder devices of the agricultural sun light green house that utilization and heat energy storage efficient are higher, solve in the prior art unreasonable because of on the arched girder apparatus structure of agricultural booth and the material, make the shortcoming that heat can not well utilize and store in the booth.
The purpose of this utility model is achieved in that a kind of two film arched girder devices of agricultural sun light green house, cambered beam that is made of light material and following arched girder; The end face of following arched girder is provided with vertical rib of projection, and cambered beam is provided with the longitudinal fluting that matches with vertical rib of following arched girder projection; Affixed plastic tunnel film between cambered beam and the following arched girder; Cover affixed plastic tunnel film on the end face of cambered beam.This pair of film arched girder device improved the utilization ratio of heat in the canopy greatly.The device that need not increase heating in the canopy in winter can be implemented in, the preference temperature of agricultural product growth in the canopy can also be guaranteed.Stronger weight capacity can guarantee that booth can stand the infringement of bad weather weathers such as strong wind, heavy snow to booth.
The utility model is because affixed one deck plastic tunnel film between the arched girder up and down, also covers affixed one deck plastic tunnel film simultaneously on the cambered beam, forms one deck air layer between this two membranes, is similar to laminated glass.It has utilized the characteristic of air heat-insulation and heat-preservation, makes that the temperature in the canopy can keep for a long time, has guaranteed that substantially the heat energy that utilizes daytime sun direct projection to produce can keep for a long time, need not in the heating of lighting a fire separately.
The beneficial effects of the utility model: 1, efficiency of utilization improves greatly, need not the heating of lighting a fire separately in the winter time in the agricultural booth; 2, structure is novel, good looking appearance, and material is light, and it is strong to bear a heavy burden, and easily adorns readily removable; Can resist boisterous infringement; 3, energy savings, economic environmental protection.China is built environment-friendly type society be significant, and can produce bigger social benefit and economic benefit.
(4) description of drawings
The utility model will be further described below in conjunction with accompanying drawing
Fig. 1 is a mounting structure schematic diagram of the present utility model;
Fig. 2 is the A-A cutaway view of Fig. 1.
(5) embodiment
Present embodiment is to be used for illustrating of the present utility model, rather than it is imposed any restrictions.
A kind of two film arched girder devices of agricultural sun light green house, as shown in Figure 1 and Figure 2, the cambered beam 1 and the following arched girder 2 that constitute by light material; The end face of following arched girder 2 is provided with vertical rib of projection, and cambered beam 1 is provided with the longitudinal fluting that matches with vertical rib of following arched girder 2 projectioies; Affixed plastic tunnel film 3 between cambered beam 1 and the following arched girder 2; Cover affixed plastic tunnel film 4 on the end face of cambered beam 1.The cross section of vertical rib of projection is shaped as rectangle or trapezoidal on the following arched girder 2.

Claims (2)

1. two film arched girder devices of an agricultural sun light green house is characterized in that: the cambered beam (1) and the following arched girder (2) that are made of light material; The end face of following arched girder (2) is provided with vertical rib of projection, and cambered beam (1) is provided with the longitudinal fluting that matches with vertical rib of following arched girder (2) projection; Affixed plastic tunnel film (3) between cambered beam (1) and the following arched girder (2); Cover affixed plastic tunnel film (4) on the end face of cambered beam (1).
