Abstract
The utility model relates to an energy-saving daylight greenhouse, relating to the facilities of agricultural greenhouse culture of vegetables, flowers, etc. The utility model is composed of a back wall, a back roof, a lighting surface which is composed of an arch steel roof frame and a plastic film and two gable walls. The back wall, the back roof and the arch steel roof frame make up an integral structure. The slope angle of the greenhouse is increased to 45-35 deg compared with the slope angle (23 deg) of an original greenhouse, which enables the light transmission quantity to be increased and the heating effect is good. The utility model has the advantages of good lighting in a low temperature period, strong loading ability and firm integral structure, which is especially suitable for the severe cold in northern winter, the driven snow areas and the protective ground for planting vegetables and amphisarca, and is an excellent facility for solving the difficult problem of obtaining vegetables in winter.
Description
Novel solar greenhouse is the facility of northern severe winter planting vegetable indispensability, relates to facility fields such as agricultural greenhouse culturing vegetable.
Plantation and the seasonal temperature of vegetables have substantial connection, eat the problem of vegetables difficulty in order to solve winter-spring season, and especially the wind and snow in the winter-spring season of northern area severe cold and high and cold district is big, and the plantation of winter-spring season vegetables becomes the key issue that is imminent.
At present mostly the greenhouse of protection ground temperature planting vegetable is to adopt plastic greenhouse, also has to do the monocline face with angle steel and adopt glass or plastic foil to do transparent covering, and roofing and monocline face roof truss are separate type thereafter, thereby are difficult to bear the load of wind and snow weight.If any the plastic greenhouse roof truss be steel pipe, but frame can not compress after plastic film is covered with apart from 12 meters bigger than normal, once meeting strong wind plastic film lifted away or tears, or because of load is not strong, torsional deformation, the greenhouse can not use for a long time.Inclination angle, existing 23 ° of greenhouses is less than normal, and the daylighting of winter low temperature phase is poor, heats bad.For overcoming the problem that existing greenhouse exists, the purpose of this greenhouse design is at northern area winter-spring season severe cold and the big characteristics of wind and snow, and it is good to make the greenhouse have hypothermic phase daylighting, and load power is strong and overall structure is firm.
This greenhouse realized by following technical scheme, and it comprises the daylighting face of Hou Qiang, back roofing arch steel roof truss and light-passing plastic film composition and two gables etc.Roofing and arch steel roof truss are connected to overall structure after it is characterized in that the back wall; And to increase be 45 °～35 ° daylighting face and ground inclination angle.
Below in conjunction with drawings and Examples the utility model is further elaborated:
Fig. 1 is a structural representation of the present utility model
Fig. 2 is an arch steel roof truss shape schematic diagram
1 is the back wall among the figure, the 2nd, and back roofing, the 3rd, the arch steel roof truss, the 4th, plastic foil (not marking among Fig. 1), the 5th, article one broken line, the 6th, the second broken line, 7 is the 3rd broken lines.
Embodiment:
The span in this greenhouse is 55 meters and 65 meters two kinds, and length can be decided because of land area, for example 50 meters.
This greenhouse is by back wall 1, back roofing 2, arch steel roof truss 3, plastic foil 4, reaches two gables.
The brick one-tenth sandwich wall of back wall 1 usefulness, nexine pseudo-ginseng, outer two or four, middle 10～12cm, in fill out dried cinder (piece or granular), can increase heat insulation effect.
Back roofing 2 adopts the thick armoured concrete slab of 60mm, and the elevation angle of back roofing is 30 °.Back roofing is as a whole with back wall cast.
Arch form steel roof truss 3 and plastic foil 4 type arched daylighting face A.The shape of arch steel roof truss is the parabola that is similar to, and (as shown in Figure 2), in the present embodiment, actual man-hour its shape of adding is limited by three broken lines, and the length of article one broken line 5 is 80～90cm, with 65～70 ° at ground inclination angle; The length of second broken line 6 is 22～25m, 40～45 ° at inclination angle; Article three, the length of broken line 7 is 18～20m, 11～20 ° at inclination angle.Arch steel roof truss 3 is to be welded (as shown in Figure 1) by Guan Gang and garden steel, and Guan Gang selects the welded tube of φ 15 for use, and the garden steel is the A of φ 12
3Steel.Steel roof truss 3 and being connected of ground are angle steel B(40 * 40 * 4 by fixing on the ground), be welded on the angle steel with one meter interval.And the other end of steel roof truss 3 and Hou Qiang top join, and are fixed on below the roof boarding of back.
Having constituted first feature in this greenhouse in sum, promptly is that the thick armoured concrete slab of 60mm of back wall 15 back roofings 2 is cast for one, and arch steel roof truss 3 joins with wall 1 top, back, and is fixed on below the roofing 2 of back, forms an overall structure.This sound construction energy Chinese People's Anti-Japanese Military and Political College wind and snow, and reach " loading code for design of building structures " standard-required, through experiment for many years, this greenhouse can bear the wind lotus (strong wind more than 11 grades) of wind speed 342m/s, snow lotus 41Kg/m
2
On the arch steel roof truss, to carry out the plastic foil 4 that covers printing opacity.
In order to cover firm plastic foil, along the greenhouse length direction one fixing angle steel (30 * 30 * 3) is arranged at roofing top, back, be welded with a shackle every one meter, its position is just at the center of adjacent two steel roof trusses.On the angle steel on ground, also be welded with corresponding half long ring.Half long ring and shackle are by garden steel 1-7/A
3Make.After plastic foil 4 is gone up in covering, compress with the galvanized wire that is fixed on half long ring and shackle, every galvanized wire of one meter pressure, plastic foil can be fixed on the arch steel roof truss 3 firmly, so just constituted arch daylighting face A.
Top and waist in the greenhouse also has two steel pipes and steel roof truss 3 welding along its length in addition, plays reinforcement effect.
Another feature of the embodiment in this greenhouse is that the inclination angle that has increased daylighting face A and ground is 45～35 °.Common theory with regard to sunshine amount, sunshine vertically impinges upon the light transmission capacity maximum on the clear covering face, increase with latitude, the altitude of the sun step-down in winter, be difficult to accomplish that the daylighting face tilt angle realization in greenhouse is vertical configuration with solar irradiation, make the corresponding increase of daylight crevice projection angle after increasing the inclination angle only, the utilization that has improved daylight reaches the energy-conservation purpose that heats.
This greenhouse has the following advantages compared with the prior art:
1. this greenhouse is overall structure, and no column, space are big, easy to operate, can adapt to the mini tractor farming, saves the labour, improves effect.
2. the inclination angle in this greenhouse big than original greenhouse (23 °) is 45～35 °, makes light transmission capacity increase by 20%, and warming effect is good, and the 0-5cm soil layer improves 6-7 ℃ of temperature.
3. the old any protection facility of the loading ratio in this greenhouse is all good, can resist strong wind more than 11 grades, can resist especially big severe snow.
