Description

Single-slope, pull rod arch skeleton for sunlight hothouse

The utility model relates to a kind of novel steel construction and the sloping pull bar arch of the list formula Sunlight greenhouse frame of reinforced concrete structure, belongs to E04.

Use no or little auxiliary thermal source; make full use of solar energy; in China North China; northeast; northwest and regional to the north of the Yangtze river basin; can realize surviving the winter winter and produce the sloping greenhouse by solar heat of list of melon-fruit-like vegetable; it is the vegetable protecting field production facility that can save the energy than traditional greenhouse significantly rising gradually of China in recent years; being subjected to users welcomes; can estimate greenhouse by solar heat because energy-conservation many; output value height; pollute little; to develop popularization rapidly at China's wide geographic area; and be expanded into and be used for nursery stock; the production of flowers and plants, even herding; the critical facility of fish production.

The sloping pull bar arch of the steel construction in the prior art and the list of reinforced concrete structure formula Sunlight greenhouse frame, wherein the steel construction bow member adopts the garden arc shape, middle " people " word reinforcing bar web member of burn-oning of top boom and lower boom, this technology can make full use of the strength and stiffness of each several part steel, thereby steel quantity consumption is bigger, and pad is more, processing and manufacturing is difficult; Another reinforced concrete structure bow member of the prior art, mix glass fiber material for strengthening concrete tension and shear behavior, in case the glass fibre powder is fallen on the plant in the greenhouse, particularly drop on the leaf vegetables product, be difficult for cleaning up, if enter human body, will be an impediment to healthy, in addition, because employing is single-row reinforcement, make the breakage rate of member in manufacturing, transportation and installation process higher.

The purpose of this utility model be exactly to provide a kind of and help more fully absorbing that solar energy, steel quantity consumption are few, structure more rationally and be convenient to the sloping pull bar arch of the novel list formula Sunlight greenhouse frame processing, transport, install and manage.

The sloping pull bar of list described in the utility model arch formula Sunlight greenhouse frame divides two kinds of steel construction and reinforced concrete structures, but but also glassing of covered with plastic film above it, if glassing must change ellipse garden shape top boom into broken line type.These two kinds of forms are formed by parts such as top boom, vertical pole, pull bar, bearing diagonal and bearings, middle no post.Be to increase the clear heat in greenhouse and increase the height of top boom bow member front portion, be beneficial to the operational administrative in the greenhouse, change the profile of top boom into ellipse garden shape bow member structure.Add a pull bar simultaneously in the top boom bottom, to reduce the horizontal thrust of top boom bow member to the back wall, pull bar one end and top boom bottom join, and the other end links to each other with bearing.Between top boom top and bearing, add a bearing diagonal again, can make the minimizing of top boom bow member internal force peak value and be tending towards even relatively.For armored concrete top boom bow member, for increasing its horizontal anti-bending strength, on its cross section, adopt double muscle configuration, do not need to mix glass fibre.

The utility model is that ellipse garden shape top boom list Pin skeleton is formed by some profiles, can be with the length in plot, the Pin number of increase and decrease skeleton, span (being span width) is 6.6 meters, 7.5 meters two kinds, highly be 3.0 meters and 3.2 meters, Xiang Yingyou adopts the series of products of different steel to select for producer or user; By the Pin spacing that the different basic wind in various places, snow load are selected skeleton for use, met in local 15 years one with interior wind, snow load to guarantee reaching opposing; Be suitable for batch production production, assembled in situ is installed.

Compared with prior art, the utility model has the advantages that: 1. save steel: steel construction saves 15～20% than existing reinforcing bar and steel-tube construction; 2. avoid polluting: reinforced concrete skeleton frame adopts the ordinary reinforced concrete material, has avoided glass reinforced concrete glass of the prior art to dredging the pollution of dish product; 3. simple in structure, easy to process, production cost is low; 4. clear span is bigger, and middle no post is convenient to farming, management; 5. the horizontal anti-bending strength of armored concrete is strengthened, and helps making, transports and installs, and can reduce spoilage.

Concrete structure of the present utility model is provided by following embodiment and accompanying drawing thereof.

Fig. 1 is the perspective view according to the sloping pull bar arch of the list that the utility model proposes formula Sunlight greenhouse frame.

Fig. 2 is according to the sloping pull bar arch of the list that the utility model proposes formula Sunlight greenhouse frame drawing in side sectional elevation.

Below in conjunction with details and the working condition of accompanying drawing detailed description according to the concrete device that the utility model proposes.

This device mainly comprises several ellipse garden shape top booms (1).When top boom (1) when being steel construction, can select for use equilateral or unequal angle, water gas pipe or thin walled welds steel pipe etc.; When top boom (1) when being reinforced concrete structure, then adopting cross section is the way of double arrangement of reinforcement, with the concrete bending resistance of stiffener, anti-crack ability.Every of vertical pole (2) is two, vertically arranges along the greenhouse.Film-pressing line (3) is when being used for press mold above the greenhouse during covered with plastic film.The available reinforcement fabrication of pull bar (4) is used to connect top boom (1) and bearing (6), and the setting of pull bar (4) is mainly used in and reduces the horizontal thrust of top boom (1) to the back wall.Establish bearing diagonal (5) in addition joins with bearing (6) on the top of top boom (1), bearing diagonal (5) is available to be made with top boom (1) identical materials, the internal force peak value that bearing diagonal (5) can reduce top boom (1) is set, and make its internal force be tending towards even, available angle steel of bearing (6) or concrete for making are embedded in it in body of wall during on-the-spot the installation.

Claims (1)

1, the sloping pull bar arch of a kind of list formula Sunlight greenhouse frame, top boom (1), vertical pole parts such as (2) are arranged, it is characterized in that top boom (1) establishes pull bar (4) for the single sloping bow member of ellipse garden shape and in the bottom of top boom (1), one end of pull bar (4) joins with top boom (1) and the other end links to each other with bearing (6), establish bearing diagonal (5) at the top of top boom (1) in addition and also join with bearing (6), bearing (6) is embedded in the body of wall when installing at the scene.
