Description

High-stress-resistance cement column special for rain shelter

Technical Field

The invention belongs to the technical field of facility agriculture cultivation, and particularly relates to a cement column special for a high-stress-resistance rain shelter.

The support is used for supporting the facility cultivation rain shelter and fixing the growth surface of the fruit branches.

Background

The pillar is the most used pillar in facility agriculture, and is one of the key components. The post mainly considers three important matters: the tensile strength, the service life and the use cost are all the first, second and third. The prop materials used in the current rain-shelter cultivation are bamboo, wood, steel pipes, section steel or cement columns and the like. The tensile strength is the strongest of the steel pipe and the section steel, the cement is inferior, and the bamboo and the wood are last; the service life is up to 20 years, the steel pipe and the section steel are 10-15 years, and the bamboo and the wood are 3-4 years; the use cost is that bamboo and wood are minimum, cement post is inferior, steel pipe and shaped steel are highest. The best cost performance of the tensile strength, the service life and the use cost is the cement column. The steel section and the cement column are used abroad, and the bamboo, wood, steel pipe and cement column are used domestically, and the steel section and the cement column are mainly used at present. The steel pipes are mainly used in standard greenhouses and multi-span greenhouses, and the cement columns are mainly used in simple greenhouses. The popularization area is the biggest among the facility agriculture at present also is simple and easy big-arch shelter.

Cement columns used at home and abroad have two general structures: one is 4 steel wires without steel holes, and the other is that the 4 steel wires are fixed by adding the steel holes. Both internal steel structures have insufficient tensile strength at the top 1 m part, and top fracture and burst often occur. In particular, a roof fixing line of the rain shelter is additionally arranged at the top, a fixing line hole for fixing the roof line is formed in the 15CM downwards at the top and is used for threading the fixed roof line, and the roof line is easy to fall off due to the fact that the top of a support column is broken by force frequently.

Disclosure of Invention

Aiming at the defects of the prior art, the invention provides the special cement column for the high-stress-resistance rain shelter, and the cement column can improve the tensile strength of the top of the cement column by adding two pairs of special steel wire frames, thereby avoiding top fracture and burst.

The technical scheme for realizing the aim of the invention is as follows:

a cement column special for a high stress-resistant rain shelter comprises a first steel bar, a second steel bar, a third steel bar, a fourth steel bar, a top steel hole, a middle upper steel hole, a middle lower steel hole, a bottom steel hole, a first steel wire frame, a second steel wire frame, a first long 8-shaped steel ring and a second long 8-shaped steel ring;

the inside of the cement column is vertically arranged in a square by a first steel bar, a second steel bar, a third steel bar and a fourth steel bar to form a rigid framework of the cement column;

the top steel hole, the middle upper steel hole, the middle lower steel hole and the bottom steel hole are respectively assembled on the first steel bar, the second steel bar, the third steel bar and the fourth steel bar, the cement column is equally divided, and more than 2 steel holes are formed in the cement column;

the top end of the cement column is symmetrically provided with a first steel wire frame and a second steel wire frame;

one ends of the first steel wire frame and the second steel wire frame are arc-shaped, one ends of the arc-shaped ends are close to the top end of the cement column, the bottom ends of the first steel wire frame and the second steel wire frame are inwards bent, the bending length is 4-5cm, and the diameter of the elbow is 2-3cm;

the first strip 8-shaped steel ring is assembled on the first steel wire frame, and the second strip 8-shaped steel ring is assembled on the second steel wire frame;

the first steel ring and the second steel ring are long-strip 8-shaped.

Advantageous effects

The invention provides a cement column special for a high stress-resistant rain shelter, which can improve the tensile strength of the top of the cement column by adding two pairs of special steel wire frames, thereby avoiding top fracture and burst;

1. two groups of steel wire frames are added at the top end of the cement column, so that the flood-fighting tensile strength is remarkably improved;

2. the method is a good method with little investment, quick response and easy popularization and application;

3. only two groups of steel wire frames are added at the top end of the cement column, so that the tensile strength of the cement column is greatly enhanced;

4. the investment cost is not greatly increased, the manufacturing difficulty is not great, and the construction is easier.
