Abstract
The present invention means a kind of concrete cable.
This rope is made of a tubular shell, wherein fills concrete, and shell forms the dual cuff of concrete bodies, has a duct of using for prestressed cable of vertically passing through in the concrete bodies at least.
The present invention is used for anchor lines, dead rope and the ropeway carrying-rope of bridge especially effectively.
Description
The present invention is a kind of concrete cable, is used for anchor lines, dead rope and the ropeway carrying-rope rope of bridge especially effectively.
According to the Preliminary Applications of concrete cable, will carry out special description to the present invention, but it not regarded as the limit of the scope of application.
As everyone knows, can particularly realize the anchor lines of offshore platform by means of steel pipe, these steel pipes have 40～60 centimetres diameter, and 2～3 centimetres wall thickness forms ， And by several sections pipe welding or mechanical connection and is wrapped on the reel.In view of the size of pipe, the size of reel is just considerable especially.
The present invention is intended to replace these pipes with concrete cable, at least when its function equates, concrete can have much smaller cross section, its weight is light, does not also need to weld assembly unit and mechanical connection ， And and can be wrapped on the much smaller reel of size, in addition, the present invention's concrete cable, because its diameter is less, surging of therefore attracting wants much weak than steel pipe.At last, concrete cable is compared with cable wire, and corrosion is wanted much insensitive.
According to the present invention, concrete cable is formed by a tubular shell, fills out in the shell and fills concrete, and shell is surrounded by the dual cuff of concrete bodies outward, has a vertically current duct of using for prestressed cable in the concrete bodies at least.
In representative production technology, cuff is made of the two-layer high tensile steel wire that is wrapped on the shell, and steel wire twines by two opposite directions, and its termination is fixed on the shell, and shell should adopt thin-wall steel tube.
A kind of better, be specially adapted in the production technology of such use, shell is made of animi resin, in its tube wall, have two-layer winding direction opposite by steel wire or the more suitable helicoid that constitutes by carbon filament.Do not limit in the present invention and adopt any certain material to constitute these helicoids, for example, equally can adopt glass yarn yet, but recommend to adopt steel wire or carbon filament.
In order to make the rope of big length, several sections bodys are docked placement in a manner described, run through therebetween with at least one public vertical elongated prestressed cable, during beginning, prestressed cable freely runs through the reserving hole channel in the concrete; But, after making finishes, should give grouting along the gap of cable wire and fill up.
Prestressed cable is traditional prestressed cable, but will recommend to adopt the carbon filament rope wrap up in the animi resin coating, or other Performance Match but to corroding insensitive material.
In order to make the described concrete cable of a basic invention, need liquid concrete is filled pipe, And applies the axial compressive force of 50MPa at least before concrete setting.
Before concrete setting, cuff is expanded owing to axial compressive force causes concrete lateral thrust effect, and after concrete setting, the cuff that trend is recovered original length forms two dimension prestressing in the pipe side direction.Before concrete setting,, or preferably for the ease of discharging because the water that effect that concrete is exerted pressure generates is provided with a drainpipe, set out the tube wall of even distribution aperture.
In typical production technology, the concrete cable that diameter is 15～20 centimetres is perhaps more superior.
In order to make concrete cable, need to adopt a covering device, comprising above-mentioned tube-like envelope, some means for the above-mentioned axial compressive force of realization, and some are the device that generates water when discharging concrete compression.In order to realize axial pressure, for example, can adopt bearing plate and a jack of being positioned at liquid concrete body two ends, this jack is bearing in wherein that a bearing plate Shang ， And strains an other bearing plate by means of cable wire.
