Abstract
The invention relates to a steel pipe member, particularly to a steel-pipe column with holes in civil engineering. The column is formed through forming holes in a steel pipe wall of a steel pipe; holes are formed in the steel pipe side wall of the hollow steel-pipe column; the holes can be annular, square and polygonal; and the steel-pipe column cross section of the hollow steel-pipe column is rectangular, annular or polygonal. The steel-pipe column is a main member in a frame structure of a building, can serve as a main member of a telegraph pole, and has the characteristics of high bearing capacity, strong rigidity, light weight, excellent plasticity and tenacity, excellent shock resistance and fatigue resistance, material saving and the like.
Description
Technical field
The present invention relates to field of civil engineering, it is a kind of open steel tubing string in definite saying.
Background technology
At present, as the steel pipe column in the building, mainly the form with real abdomen formula occurs, and steel pipe is entity from without, does not have the cavity.Modal is exactly the steel pipe electric pole, although we can see that appearance can be circular, or polygon, all there is not the cavity on the steel plate.Like this, will cause the waste of steel.
Paper and Patent from retrieval not yet carry out for the research of this respect.
The inventor had once applied for " opening-type steel tube concrete column " patent (publication number: CN102505803A) in 2011, paper the problem of hole-opening on the sidewall of steel core concrete column, but it starts mode for place apparatus conveniently arranges, and need to punch simultaneously on steel plate and concrete simultaneously.
And only hole-opening on steel pipe walls of the present invention does not have concrete in it.
From preliminary analysis, the present invention has advantages of can saving steel, does not affect functional performance simultaneously.
Summary of the invention
The objective of the invention is to be achieved through the following technical solutions: form by opening pertusate steel plate on the steel pipe walls.
Advantage of the present invention and effect are:
1. under the prerequisite that guarantees bearing capacity, have hole on the steel pipe walls, alleviated deadweight, constructability;
2. for the larger place of countryside wind-force, when using as electric pole, can reduce the impact of wind-force.
Description of drawings
Fig. 1 is that column section is square perforate steel pipe column schematic diagram.
Fig. 2 is that column section is circular perforate steel pipe column schematic diagram.
Fig. 3 is that column section is polygonal perforate steel pipe column schematic diagram.
The specific embodiment
The present invention is the main member of building frame structure in the building, also can be used as the main member of electric pole, has a bearing capacity high, and rigidity is large, lightweight, plasticity, good toughness, and shock resistance and anti-fatigue performance are good, the characteristics such as economical with materials.
The open steel tubing string has hole 2 at hollow steel tubing string steel pipe sidewall 1.The employing conventional method punches.
Hole 2 hole forms can be circular, square, polygon.Hollow steel tubing string steel pipe column cross section is rectangle or circle or polygon.
Claims (3)
1. the open steel tubing string is characterized in that: have hole (2) at hollow steel tubing string steel pipe sidewall (1).
2. open steel tubing string according to claim 1, it is characterized in that: hole (2) hole form can be circular, square, polygon.
3. open steel tubing string according to claim 1, it is characterized in that: hollow steel tubing string steel pipe column cross section is rectangle or circle or polygon.
