Description
Technical field
The utility model belongs to manufacture field, tall and slender structure basis, relates to the scope of application and be the tall and slender structures such as wind power generation stepped, TV transmission tower under various geological conditionss, tour tower, beacon tower, is particularly specifically related to a kind of prestressing force and supports crab-bolt.
Background technology
Prestressing force supports one of vitals that crab-bolt connects as wind-power generating unit tower foundation structure, the swing when bearing wind-force and acting on the vibration of thrust on impeller, moment of torsion, moment of flexure, gyroscopic couple, motor and stressed variation etc.Particularly to blower foundation is this, bear tired power actuated crab-bolt, be positioned at the bottom of pylon, often, in environment such as concrete, salt affected soil, humidity, marsh, seawater, antiseptic property of the installation accuracy of anchor component, mechanical property and crab-bolt etc. is had to very high requirement.It is ring-like that common tall and slender structure is mainly basis with basis, its structure is comprised of encorbelment base plate and tower foundation ring buried section, basis, this type of basic and suitable foundation condition matches and can reach good Compressive Bearing Capacity, so have employing in housing construction base for post more.But for wind power generation stepped, superstructure is to basic active force master if it were not for pressure but moment of flexure, so anti-pressure ability is had a surplus, bending resistance is not enough, thereby has caused the larger waste of basic engineering, less economical.And this type of base form is too single, can not adapt to the different geological conditionss such as saline and alkaline, beach; Discharge ring diminishes suddenly the stressed maximum cross-section of Foundation pier strength and stiffness, easily causes stress to concentrate with fragility broken.
Summary of the invention
For the deficiency in existing technology, the purpose of this utility model is to invent a kind of antiseptic property that can effectively improve prestressing force crab-bolt, improves positioning precision and axiality, applies the prestressing force of pretension accurately and supports crab-bolt.
For achieving the above object, adopted technical scheme of the present utility model is:
Prestressing force supports a crab-bolt, by crab-bolt polished rod, crab-bolt sleeve pipe, upper crab-bolt bobbin seal plug, lower crab-bolt bobbin seal plug, upper heat shrinking sleeve, lower heat shrinking sleeve, polished rod section heat shrinking sleeve, adjusting nut, Supported Nylon nut, is assembled.It is characterized in that described Supported Nylon nut is positioned at the top of crab-bolt polished rod, adjusting nut is positioned at the bottom of crab-bolt polished rod, described upper heat shrinking sleeve is installed on the top of crab-bolt polished rod, on Supported Nylon nut, described polished rod section heat shrinking sleeve is positioned under the Supported Nylon nut on crab-bolt polished rod top, described crab-bolt casing pipe sleeve is outside at crab-bolt polished rod, its upper end is inserted in polished rod section heat shrinking sleeve, between crab-bolt polished rod and crab-bolt sleeve pipe and upper heat shrinking sleeve, be equipped with crab-bolt bobbin seal plug, described lower heat shrinking sleeve is installed on the adjusting nut of bottom of crab-bolt polished rod, the described crab-bolt sleeve pipe lower end that is enclosed within crab-bolt polished rod outside is inserted in lower heat shrinking sleeve, between crab-bolt polished rod and crab-bolt sleeve pipe and lower heat shrinking sleeve, be equipped with lower crab-bolt bobbin seal plug.
Described crab-bolt polished rod is processed through whole Dacroment, makes crab-bolt have water resistance, humidity resistance, salt spray corrosion resistance.
Polished rod section heat shrink cover after described Dacroment is processed further improves crab-bolt antiseptic property.
Described crab-bolt casing pipe sleeve is in crab-bolt polished rod outside, between crab-bolt polished rod and crab-bolt sleeve pipe, use crab-bolt bobbin seal plug, can prevent from pouring into a mould base concrete enters from crab-bolt cannula tip, also can play the effect of precise positioning crab-bolt sleeve pipe, improve the axiality of crab-bolt sleeve pipe and crab-bolt polished rod, described crab-bolt sleeve pipe two-port continues to tighten up with heat shrinking sleeve, further guarantees to isolate with crab-bolt outside environment.
Described crab-bolt top, bottom adopt respectively Supported Nylon nut and regulate steel nut location, work to support, locate upper and lower anchor slab.
Described employing high-strength bolt hydraulic stretching device applies pretension accurately to crab-bolt, upper and lower anchor slab is exerted pressure to steel concrete, and when basis is subject to Moment, concrete compressive stress discharges but to some extent all the time in pressured state, there will not be crack, improved concrete durability.Supported Nylon nut adopts nylon material, and rising can be destroyed while drawing, and does not affect after tower cylinder installs, to carry out crab-bolt and rise and draw.
Further illustrate, a kind of prestressing force of the utility model supports crab-bolt, and above-mentioned all parts are all at produce in factory.
Further illustrate, crab-bolt polished rod is processed through whole Dacroment, add crab-bolt sleeve pipe, crab-bolt bobbin seal plug, heat shrinking sleeve, make it to isolate with outside environment, utilize anchor slab under the leveling of steel nut, nylon nut to regulate upper anchor slab position degree, finally adopt high-strength bolt hydraulic stretching device to apply pretension accurately to crab-bolt.
The scope of application of the present utility model is the tall and slender structures such as wind power generation stepped, TV transmission tower under various geological conditionss, tour tower, beacon tower.
Usefulness of the present utility model is:
A kind of prestressing force supports crab-bolt, can effectively improve the antiseptic property of prestressing force crab-bolt, utilize being sealed and matched of crab-bolt bobbin seal plug, heat shrinking sleeve and crab-bolt sleeve pipe to make crab-bolt and external environment isolation, prevent that prestressing force from supporting the corrosion that crab-bolt is subject to when base concrete is poured into a mould, or severe geological environment is as the long-term erosion of marsh, beach etc.Secondly in the positioning precision adding between prestressing force crab-bolt and crab-bolt sleeve pipe between crab-bolt bobbin seal plug raising prestressing force crab-bolt and crab-bolt sleeve pipe, improve axiality.Crab-bolt top, bottom adopt respectively Supported Nylon nut and regulate steel nut location, work to support, locate upper and lower anchor slab.Adopt high-strength bolt hydraulic stretching device to apply pretension accurately to crab-bolt, upper and lower anchor slab is exerted pressure to steel concrete, and when basis is subject to Moment, concrete compressive stress discharges but to some extent all the time in pressured state, there will not be crack, improved concrete durability.Supported Nylon nut adopts nylon material, and rising can be destroyed while drawing, and does not affect after tower cylinder installs, to carry out crab-bolt and rise and draw.More outstanding usefulness is that the utility model has better crab-bolt sleeve pipe two-port sealing corrosion effect, better crab-bolt sleeve pipe assembling and positioning effect, the axiality effect of better crab-bolt and sleeve pipe, after adopting hydraulic expanding to draw, there is better mechanical property, heat shrinking sleeve that the utility model adopts sealing, location, cheap, good economy performance, easy for installation.
