Description

The steel truss greenhouse by solar heat

Technical field

The utility model relates to a kind of greenhouse, relates in particular to a kind of steel truss greenhouse by solar heat.

Background technology

Growth and the seasonal temperature of plant such as vegetables, flowers are closely related, and be low at the winter-spring season temperature of northern area intemperance, and plant is difficult for growth.In order to solve the problem plants such as winter-spring season planting vegetable, flowers, the technical scheme that adopts is to utilize the function of light transmissivity of Sunlight Greenhouse and protection ground temperature, plant such as planting vegetable, flowers in greenhouse by solar heat at present.Now, widely used greenhouse by solar heat, it comprises the gable of Hou Qiang, domatic, the arched frame in back, the column that is used to support arched frame, both sides and as the plastic foil of daylighting face, the domatic one that is cast for of Hou Qiang and back, the two ends of back wall and the gable of both sides are cast for one, arched frame and Hou Qiang top join, and be fixed on the back domatic below, all be equipped with apart from the vent window of ground 1-1.2 rice on the gable of both sides.It is domatic that this greenhouse by solar heat has the back, the domatic outside, back is a cement plate, the inboard is a plastic foam, because winter, back domatic wind area was big based on northwester, the heat in the greenhouse scatters and disappears very easily from here, heat insulating ability is poor, be unfavorable for the growth of plant, simultaneously, be unfavorable for that also straw mat is deposited and manual operation; Because the column that supports arched frame is installed in the greenhouse, increased cost, also be unfavorable for mechanized operation; The vent window position of installing on the gable of both sides during winter ventilation, very easily makes in the outdoor cold air inlet chamber on the lower side, causes plant to damage to plants caused by sudden drop in temperature; In addition, the body of wall of back wall and gable is thin, and is solid wall, and heat-insulating property is poor.

Summary of the invention

The utility model purpose provides a kind of steel truss greenhouse by solar heat of good heat insulating.

For achieving the above object, the technical solution adopted in the utility model is: a kind of steel truss sight greenhouse, gable, steel truss and coverlay comprising front wall, Hou Qiang, both sides, the and arranged on left and right sides limit of front wall and the gable on both sides connect as one, the and arranged on left and right sides limit of back wall and the gable on both sides connect as one, coverlay covers on the steel truss, and vent window all is installed on the gable on both sides, and its characteristics are: the surface plate of the fixedly connected horizontal positioned of top margin of back wall; Fixedly connected with the surface plate on front wall, the back wall respectively in the two ends of steel truss.

The utility model substitutes the domatic design in back by using surface plate, has reduced wind area greatly, has strengthened the heat insulation effect in the winter greenhouse, has made things convenient for straw mat to deposit and manual operation; The utility model has saved pillar construction in design, has both reduced cost, has made things convenient for mechanized operation again.

Description of drawings

Fig. 1 is a kind of structural representation of the present utility model.

Embodiment

The utility model will be further described below in conjunction with the drawings and specific embodiments.

A kind of steel truss greenhouse by solar heat, as shown in Figure 1, gable 4, steel truss 2 and coverlay 9 comprising front wall 1, back wall 13, both sides, the and arranged on left and right sides limit of front wall 1 and the gable on both sides 4 usefulness common methods connect as one, and the and arranged on left and right sides limit of back wall 13 and the gable on both sides 4 usefulness common methods connect as one; Fixedly connected with the surface plate 11 usefulness common methods on front wall 1, the back wall 13 respectively with the surface plate 11 of the fixedly connected horizontal positioned of common method, the two ends of steel truss 2 in the top of back wall 13; The top fixed installation of back wall 13 is useful on the bracing frame 10 of supporting steel truss 2, the lower end of bracing frame 10 is fixedly mounted on the madial wall of back wall 13, fixedly connected with the top of steel truss 2 obliquely in the upper end of bracing frame 10, bracing frame 10 adopts 50 * 50 * 5 angle steel; The inside of steel truss 2 has the stay pipe 3 of three steel to pass, and the two ends of stay pipe 3 are fixedly mounted on respectively on the gable 4 on both sides; All have three vent windows on the gable 4 on both sides, comprise that of top is equipped with the vent window 5 in summer that the winter ventilation window 7 of small fan 8 and bottom two are equipped with big fan 6; Winter ventilation window 7 is high 0.6 meter apart from 2.2 meters on ground, wide 0.5 meter; Summer, vent window 5, and is high 1.7 meters apart from 0.2 meter on ground, wide 1.5 meters; The thickness of wall body of the gable 4 on back wall 13, both sides is 0.9 meter, all has sandwich wall 12 in the middle of the body of wall, is filled with flyash or straw in the sandwich wall 12; Coverlay 9 covers on the steel truss 2, and its two ends are separately fixed on front wall 1, the surface plate 11.

The utility model has strengthened the heat insulation effect in the winter greenhouse by increasing thickness of wall body, design sandwich wall and use surface plate to substitute the domatic design in back in the middle of body of wall, has made things convenient for straw mat to deposit and manual operation; The utility model has saved pillar construction in design, has both reduced cost, has made things convenient for mechanized operation again, adopts bracing frame and stay pipe structure, has improved the stability and the bearing capacity of steel truss; In the utility model on the gable on both sides the design winter ventilation window is arranged, be convenient to the winter ventilation hydrofuge, two summer vent window, it is aeration-cooling to be convenient to summer.
