By the device, if the height of the tower crane is greater than an independent height, the rectangular sleeves are arranged at the periphery of the tower crane, and the wind damper is arranged in the top rectangular sleeve; by the wind damper, most energy of wind can be counteracted; the swing degree of the tower crane is reduced; and the tower crane can be balanced.

Description

Coasting area tower crane bracing means
Technical field
The present invention relates to a kind of coasting area tower crane bracing means.
Background technology
In the middle of China's modernization construction process, tower crane is being brought into play very important effect, but due to it self characteristic, once there is tower crane collapse accident, will cause personnel and the immeasurable consequence of economic aspect.In coasting area, consider typhoon comparatively frequently and the higher factor of wind-force intensity, when high wind is attacked, tower crane probably collapses under wind-force effect.Tradition tower crane adopts wall attaching rod to be connected and to reinforce with building, does the used time being subject to wind-force, and wall attaching rod is tension both, and pressurized again will cause tower crane collapse because wall attaching rod slenderness ratio is sometimes excessive or connection mode is lack of standardization.And under many circumstances, building and tower crane have gap to cause wall attaching rod not use on height range.Have build industry or steel building time, if use wall attaching rod at building surface, carry out tower crane reinforcing, need check and approve through the calculating of engineering design side, process is loaded down with trivial details.
Summary of the invention
For problems of the prior art, the object of the present invention is to provide the technical scheme of a kind of coasting area tower crane bracing means.
Described coasting area tower crane bracing means, this bracing means is arranged on tower crane tower body, it is characterized in that described bracing means consists of some pipe links, some attaching partss, some strut bars, some cable wires, some rectangular sleeve and a wind damper, rectangular sleeve be fixed by socket on tower crane tower body and from the bottom up diameter reduce successively, between adjacent rectangular sleeve, be connected with cable wire; Wind damper is connected on tower crane tower body by supporting cable wire, and wind damper body is positioned at top layer rectangular sleeve, and contacts with the hydraulic efficiency gear that is arranged on top layer rectangular sleeve surrounding; Strut bar be arranged between bottom rectangular sleeve and ground and be arranged on ground pipe link and be connected, between pipe link and strut bar, by attaching parts, be connected.
Described coasting area tower crane bracing means, is characterized in that described cable wire upper end is connected with tower crane tower body with top rectangular sleeve inwall, and cable wire lower end is connected with bottom rectangular sleeve outer wall.
Described coasting area tower crane bracing means, is characterized in that described strut bar is set to eight, and each angle of bottom rectangular sleeve connects two, and the pipe link being connected with strut bar is also set to eight, and eight pipe links surround octagon.
Described coasting area tower crane bracing means, is characterized in that the angle between described strut bar and ground is 45 degree.
Described coasting area tower crane bracing means, is characterized in that described attaching parts is fixed on the cement concrete on ground by the mode of chemically-planted steel bar.
The present invention is after tower crane height is greater than unattached height, in tower crane periphery, rectangular sleeve is set, and in top layer rectangular sleeve, wind damper is set, and utilizes wind damper to offset the energy of most of wind, reduces the degree of waving of tower crane, makes tower crane balance; Between bottom rectangular sleeve and ground, strut bar is set and is connected with pipe link, can increase whole stability; By bracing means of the present invention, the frequent area of coastal typhoon and the larger region of wind-force are not used wall attaching rod just can solve the problem that tower crane is reinforced.

The specific embodiment
Below in conjunction with Figure of description, the present invention is elaborated:
Coasting area tower crane bracing means, this bracing means is arranged on tower crane tower body 9, this bracing means consists of some pipe links 1, some attaching partss 2, some strut bars 3, some cable wires 4, some rectangular sleeve 5 and a wind damper 6, rectangular sleeve 5 be fixed by socket on tower crane tower body 9 and from the bottom up diameter reduce successively, between adjacent rectangular sleeve, be connected with cable wire 4, cable wire 4 upper ends are connected with tower crane tower body 9 with top rectangular sleeve inwall, and cable wire 4 lower ends are connected with bottom rectangular sleeve outer wall; Wind damper 6 is connected on tower crane tower body 9 by supporting cable wire 7, wind damper body is positioned at top layer rectangular sleeve, and contact with the hydraulic efficiency gear 8 that is arranged on top layer rectangular sleeve surrounding, wind damper connecting structure and principle of work are prior art, do not repeat them here; Strut bar 3 be arranged between bottom rectangular sleeve and ground and be arranged on ground pipe link 1 and be connected, between pipe link 1 and strut bar 3, by attaching parts 2, be connected, attaching parts is fixed on the cement concrete on ground by the mode of chemically-planted steel bar; Between strut bar 3 and ground, angle is controlled between 35-55 degree, is preferably 45 degree, strut bar 3 can be set to eight, each angle of bottom rectangular sleeve connects two, the pipe link 1 being connected with strut bar 3 is also set to eight, and eight pipe links surround octagon, increase whole stability.
The invention solves the frequent area of coastal typhoon and the larger region of wind-force must use wall attaching rod to carry out the problem of tower crane reinforcing.Particularly, after coastland tower crane height is greater than unattached height (being that tower crane height exceeds standard), need rectangular sleeve be set being greater than part, itself and tower crane are fastenedly connected, under this height to can one or two rectangular sleeve being set according to actual conditions between ground, nethermost rectangular sleeve is referred to as bottom rectangular sleeve, on unattached height, every 10 meters, a rectangular sleeve is set afterwards, between rectangular sleeve, use cable wire firmly to connect, and the rising along with height, the volume of rectangular sleeve is along with dwindling, more up rectangular sleeve is less for it, bottom rectangular sleeve is maximum, the object of doing is like this area exposed to the wind that reduces tower crane eminence, connection by cable wire and bottom support bar be used for the whole stability that increases tower crane.
Be positioned at uppermost rectangular sleeve and be referred to as top layer rectangular sleeve, wind damper is set in top layer rectangular sleeve, wind damper is installed together with top layer rectangular sleeve.Wind damper is comprised of basic building blocks such as mass, support cable wire and hydraulic efficiency gear.The effect of wind damper is, when high wind is attacked from certain direction, the detectable wind-force size of sensor in wind damper and the swing degree of rocking of tower crane, computer controlled hydraulic efficiency gear regulates and controls mass along the counter motion of wind direction, make wind damper produce a kind of strength contrary with wind attacking direction, major part has been offset the energy of wind, has reduced the degree of waving of tower crane, balance tower crane, prevent tower crane collapsing under wind-force effect.
