Description

Technical Field

[0001] The utility model relates to a breeding greenhouse with an ultra-large concrete column mesh structure, belonging to the technical field of greenhouses. Background Art

[0002] Greenhouse, also known as plastic film arch shed, is an important agricultural facility, mainly used to provide a relatively closed and controllable growth environment for crops or for internal aquaculture.

[0003] A greenhouse primarily consists of two parts: a framework and a covering. The framework can be made of a variety of materials, including bamboo or wooden poles, concrete poles, and lightweight steel or pipes. These materials are used to construct the columns, tension rods, arch rods, and compression rods that form the greenhouse's support structure. The covering is primarily made of plastic film, which offers excellent light transmittance and thermal insulation properties, ensuring optimal light and temperature conditions for the crops within.

[0004] Greenhouses are typically arched or ridged in shape, enhancing their stability and wind resistance. They typically occupy a large area, typically over 300 square meters, with heights ranging from 2 to 2.5 meters. Multi-span greenhouses can exceed 3 meters in height, with widths or spans ranging from 8 to 15 meters and lengths ranging from 30 to 60 meters. These dimensions create a spacious interior, conducive to crop growth and agricultural operations.

[0005] The inventors have discovered that the prior art has at least the following technical problems:

[0006] Existing super-large greenhouses are made of steel structures, which have high material costs, long construction cycles and high labor costs during the manufacturing process. Utility Model Content

[0007] The technical problem to be solved by the utility model is: to overcome the deficiencies of the prior art and provide a breeding shed with an oversized concrete column mesh structure, concrete column support, pull rope assembly, and modular construction.

[0008] The super-large concrete column mesh structure breeding shed described in the utility model includes several concrete columns, which constitute several support points. Pulling ropes are connected between the concrete columns, and the pulling ropes between the concrete columns form a mesh structure. Pulling ropes are connected between the concrete columns located at the edge positions and the ground. The upper ends of the concrete columns are covered with covering materials, and the center of the covering material on the top of the concrete columns gradually decreases towards the surrounding areas.

[0009] Furthermore, the concrete column includes a support seat arranged at the lower end, a support column is fixed on the support seat, a pull rope fixing cylinder is installed at the upper end of the support column, a threading clamp is installed at the upper end of the pull rope fixing cylinder, and a protective cap is installed at the upper end of the threading clamp.

[0010] Furthermore, a chuck is installed on the support column near the support seat.

[0011] Furthermore, a tensioning device is installed on the pulling rope.

[0012] Furthermore, the pulling rope is a steel cable, which includes a parallel steel wire bundle, steel strand or steel wire rope composed of high-strength steel wires.

[0013] Furthermore, a heat-insulating device is installed on the concrete column inside the covering material. The heat-insulating device includes a support frame installed on the concrete column, a roller shutter machine is installed on the support frame, and a heat-insulating curtain is installed on the corresponding reel of the roller shutter machine.

[0014] Furthermore, a lifting mechanism is installed below the heat preservation device, and the lifting mechanism is used to lift the moving heat preservation curtain, so that the heat preservation curtain can pass over obstacles during the movement.

[0015] Furthermore, a pull plate is pre-buried in the ground, and the concrete column located at the edge is connected to the pull plate through a pulling rope.

[0016] Compared with the prior art, the beneficial effects of the present invention are:

[0017] The utility model is made of concrete columns with low material cost. It adopts pulling ropes for support and fixation of the concrete columns in multiple aspects. The concrete columns and pulling ropes form a mesh structure as a whole. The force points of each concrete column are more stable, making the overall structure simple, the force points are stable and the combined force is balanced, and the ability to resist wind, rain and snow weather is strong.

The pulling ropes 2 between the concrete columns 1 constitute a mesh structure. Pulling ropes 2 are connected between the concrete columns 1 at the edge and the ground. The upper end of the concrete column 1 is covered with covering material 3. The center of the covering material 3 on the top of the concrete column 1 gradually decreases towards the surrounding areas. The covering material 3 is usually made of plastic film, and the covering material 3 can choose a double-layer structure plastic film.
