Problems solved by technology

[0002] At present, vegetable greenhouses, breeding greenhouses and simple greenhouses for storage mainly use steel pipes or bamboo to form supports, and then cover them with tarpaulins. This kind of greenhouses not only has a complex structure, but also requires many supports inside the small span, and the firmness is not high enough. and short life

Embodiment 1

[0021] Build a large-span greenhouse with an integrated structure of ground piles and frames. This scheme is more suitable for implementation when the amount of construction is small and the specifications of the greenhouses are inconsistent.

[0022] First drill a deep well underground, the depth of the well is proportional to the span of the greenhouse, and the cross section of the well is greater than or equal to the cross section size of the frame.

[0023] Then build the formwork for the frame on the side of the well, place the ground piles and the steel bars inside the frame, and the steel bars should be an integral structure.

[0024] Then pouring with concrete (leave the hole (4) that wears steel cable when pouring, also can leave the hole or pit of fixing fixed pulley). After the concrete is solidified, the formwork is removed to form the frame (1), the reinforced concrete pile (2) and the hole (4) of the integrated structure.

[0025] Set up diagonal braces (not sh...

Embodiment 2

[0032] Build ground piles and frames to form a large-span greenhouse. This scheme is especially suitable for large-scale construction of greenhouses with standard specifications, and the construction time is relatively short using this scheme.

[0033] Process the reinforced concrete soil pile (2) and the frame (1) of the standard specifications in the factory (the connection work should be done in advance at the joint during processing) and transport the reinforced concrete soil pile (2) to the construction site with a pile driver ) into the ground and then connect the frame (1) above the ground pile.

[0034] The remaining roof weaving and tarpaulin covering methods are the same as in Embodiment 1.

[0035] This scheme is also especially suitable for the construction of multi-span greenhouses. When building multi-span greenhouses, two adjacent sheds can share a ground pile and a section vertical to the ground on the frame. The holes on the two adjacent frames only need to b...

Abstract

The invention relates to the technical field of structural engineering, in particular to a large-span greenhouse. The large-span shed is characterized in that a pair of parallel arched frames is arranged on reinforced concrete piles inserted into underground, equidistant holes are reserved in the frame, and fixed pulleys are arranged beside the holes; and a steel cable is connected from a starting hole of one frame to a corresponding hole of the other frame and then turns back by connecting the next hole after winding a fixed pulley set, and such repeat connection of the steel cable and all the equidistant holes in the frames form a woven roof of the greenhouse, the end of the steel cable is fastened by a tension device fixed on the last hole of the frame, so that a greenhouse structure is formed. Compared with an existing greenhouse basically the same with the large-span greenhouse, the large-span greenhouse is simple in structure, strong in firmness, long in service life and large in span. Besides, the large-span greenhouse, when used for planting, breeding and storing, is convenient to farm or to store and transport goods in the greenhouse therein.

Description

technical field [0001] The invention relates to the technical field of structural engineering, in particular to a large-span greenhouse. Background technique [0002] At present, vegetable greenhouses, breeding greenhouses and simple greenhouses for storage mainly use steel pipes or bamboo to form supports, and then cover them with tarpaulins. This kind of greenhouses not only has a complex structure, but also requires many supports inside the small span, and the firmness is not high enough. and short life. Contents of the invention [0003] In order to solve the above technical problems, the present invention provides a large-span greenhouse, which has a large span, simple structure, strong firmness and long service life. [0004] This large-span greenhouse proposed by the present invention mainly contains reinforced concrete piles, frames, fixed pulleys, steel cables, tensioning devices and tarpaulins. The utility model is characterized in that an arched frame is arran...
