Description

A large-span all-steel solar greenhouse skeleton

technical field

The utility model relates to a building material, in particular to a large-span all-steel solar greenhouse framework for greenhouse arch beams and beams. the

Background technique

At present, most of the domestic greenhouse skeletons are welded with steel pipes and steel bars as the beams and longitudinal beams of the greenhouse. The disadvantage is that welding must be carried out on site. Welding cannot be realized in areas that are not connected to the power grid in the western agricultural and pastoral areas, and the longitudinal and longitudinal beams of the welded Too many diagonal tie rods welded between the beams will affect the lighting in the greenhouse. Some greenhouse skeletons use arc-shaped profiles formed by cold-bending and rolling square tubes on special rolling equipment as the greenhouse skeleton, and the cost is too high. There are also cement greenhouse skeletons, but as the demand for greenhouses increases, the span of the greenhouses is also increasing, and the cement greenhouse skeletons do not meet the requirements of large spans for the strength of the arch. the

Contents of the invention

The technical problem to be solved by the utility model is to provide a high-strength light-duty large-span all-steel structure sunlight greenhouse frame for the deficiencies in the prior art. the

The skeleton of a large-span all-steel structure sunlight greenhouse of the utility model is realized through the following technical scheme: The skeleton of a large-span all-steel structure sunlight greenhouse of the utility model includes steel pipe joints, main beams, beams, greenhouse doors, Steel wire buckle, plastic film, filling composite material, the splicing part of the steel pipe of the main beam is fixed with screws after shrinking and socketing, the intersection of the main beam and the cross beam is clamped with steel wire buckle, and the front side of the greenhouse skeleton is mainly There is a greenhouse door at the first pole of the beam. the

Compared with the prior art, a large-span all-steel solar greenhouse framework of the utility model has the following beneficial effects: Since the utility model greenhouse framework adopts a steel pipe to be coated with a plastic film to carry out anti-corrosion treatment on the steel pipe framework, the temperature is increased. The service life of the shed skeleton. The steel pipe is filled with glass fiber composite cement or pure cement, which greatly increases the strength of the skeleton, so there is no need to set up columns in the greenhouse of the utility model, which improves the usable area of the greenhouse; because the skeleton of the greenhouse of the utility model is in the main There is a greenhouse door on the front side of the beam, and tractors and other agricultural production machinery can be driven into the greenhouse for work, which improves the production efficiency of the greenhouse. The steel pipe of the utility model is used as the beam and the main beam of the greenhouse, and is installed with a building row frame structure without welding, and only needs to use steel wire buckles to connect the intersection of the beam and the main beam. This connection method not only improves the strength of the skeleton. Balanced performance without breaking like welding. When the main girder needs to be connected with more than two steel pipes, the necking machine is used to process the necking at one end of the steel pipe. During installation, it is only necessary to insert the steel pipe at the necked end to the unshrinked steel pipe end of the other steel pipe to complete. The utility model is a large-span all-steel solar greenhouse with simple skeleton structure, convenient installation and use, high compressive strength and good balance performance. The utility model is a large-span all-steel solar greenhouse frame structure suitable for use in all solar greenhouses. the
