The specific embodiment
embodiment 1:
The utility model divides by its function, can be used in combination, and also can use by single functional independence.While being used in combination as accompanying drawing 1, the utility model is arranged on body support structure, be articulated and connected with supporting construction, with adaptive stay cable, produce the swing of deflection deformation backstay end, so, the utility model is being installed on body abutment steel work 6 by ball-and-socket cushion block 5, and realization is articulated and connected, and the 13rd, other envelope is modified face.Spring 4 in the utility model can be cylindrically coiled spring, can be also disk spring; Can be one group of spring, can be also many group springs; If employing disk spring, can be monolithic cluster spring, can be also superimposed cluster spring, involutory cluster spring.Drag-line gag lever post 1 and drag-line connecting screw rod 7 link into an integrated entity by thread bush, spring 4 is put into spring guide cylinder 2, spring guide cylinder 2 is arranged on ball-and-socket cushion block 5, and drag-line connecting screw rod 7 is through spring 4, ball-and-socket cushion block 5 in guide cylinder 2, and the stay 8 of screwing on is fixedly connected with dragline anchorage 9.According to the drag-line pretightning force of design, drag-line connecting bolt is carried out to stretch-draw, guarantee that spring 4 reaches maximum pressured state, and reserve free gap e by designing requirement, tighten stay 8, seal up the top cover of spring guide cylinder 2.According to designing requirement, reserve free gap f, fixing overload limited block 3, fastening nut.
While installing at the construction field (site); stay 8 on handle assembly screws down, more locking overload protection arrangement is arranged on to body support structure correspondence wears on the position of drag-line connecting screw rod 7, the stay 8 of screwing on drag-line connecting screw rod 7; and connect dragline anchorage 9, drag-line is carried out to pretension.The installation process of curtain wall is same as the prior art.
On drag-line gag lever post 1 of the present utility model, have a thin neck A-A, its bearing capacity is the overload restraint of drag-line 10; Between drag-line gag lever post 1 and spring guide cylinder 2 top covers, leave free gap e, when drag-line 10 is lax, spring 4 extends, and makes drag-line 10 maintain certain prestressing force, guarantees that drag-line 10 was unlikely pine; 2 of drag-line limited block 3 and spring guide cylinders leave free gap f, and during drag-line 10 overtighten, spring 4 compressions shorten, and overload limited block 3 and spring guide cylinder 2 top covers are adjacent to; When drag-line 10 pulling force continue to strengthen, drag-line gag lever post 1 pulling force also continues to strengthen, and while reaching the drag-line overload restraint of drag-line gag lever post 1, the thin neck A-A place on drag-line gag lever post 1 is pulled off, elastic force by spring 4 maintains drag-line 10 internal force a suitable scope, does not make drag-line 10 disrumpent feelings.
It is K that setting drag-line pretightning force F0, drag-line allow minimum internal force F1, spring rate, e=(F0-F1)/K
Setting causes that the super stretch-draw displacement of drag-line is that f, drag-line overload restraint is that the stretch breaking strength of F2, overload limit rod material is that W, the overload thin neck of limit rod place sectional area are (F2-F0)/W, and displacement is f=(F2-F0)/K.
The maximum pressured state of spring is the state that applies drag-line pretightning force.When drag-line internal force increases, while even reaching maximum load compound action, the pulling force of top portion drag-line gag lever post is born load, so the axle power of spring can be pressed drag-line pretightning force value.
As long as strict, calculate the long-pending size of the thin throat area of drag-line gag lever post, apply spring deflection corresponding to pretightning force, choose reasonable spring, just can realize the locking and overload protection function of drag-line.
When drag-line of the present utility model is subject to temperature or wind action, drag-line extends, and makes drag-line produce stress relaxation, in device, leave the free gap e of drag-line when lax, spring can correspondingly extend, and keeps drag-line to have the pretightning force of a permission, guarantees the safe handling of curtain wall.When drag-line internal force constantly increases, while even reaching maximum load compound action, the pulling force of top portion drag-line gag lever post is born load, when the load action being subject to when drag-line surpasses maximum permissible value, in device, the thin neck of drag-line gag lever post can be pulled off, and now the elastic force by spring is out of shape to maintain drag-line internal force a suitable scope, and drag-line is not pulled off, work on, guarantee the safe handling of curtain wall.
embodiment 2:
While being used in combination, as accompanying drawing 2, the utility model also can be arranged under body support structure, by hanging otic placode 14 and embedded part 15, is connected on steel concrete supporting construction 16, and realization is articulated and connected.Drag-line connecting screw rod 7 is through the spring 2 in guide cylinder 2, and the stay 8 of screwing on is fixedly connected with dragline anchorage 9, has a thin neck B-B on drag-line gag lever post 1.According to the drag-line pretightning force of design, drag-line 10 connecting bolts are carried out to stretch-draw, guarantee that spring 4 reaches maximum pressured state, tighten stay 8.And reserve free gap f by designing requirement, and fixing overload limited block 3, fastening nut, then reserve free gap e by designing requirement, seal up the top cover of spring guide cylinder 2.
When install job site, the utility model is directly installed on the connection otic placode 14 on body support structure, and bearing pin is fixed.On drag-line connecting screw rod 7, connect dragline anchorage 9, stay 8 unclamps, and drag-line 10 is carried out to pretension, then tightens stay 8.The installation process of curtain wall is same as the prior art.Operating principle is identical with embodiment 1.
embodiment 3:
As accompanying drawing 3, accompanying drawing 4, when the utility model only plays locking protective effect, drag-line gag lever post and overload limited block are cancelled, free gap e when reservation drag-line is lax.When drag-line 10 relaxes because of a variety of causes, spring 4 can correspondingly extend, and keeps drag-line 10 to have the pretightning force of a permission, guarantees the safe handling of curtain wall.
embodiment 4:
As accompanying drawing 5, accompanying drawing 6, when the utility model only plays overload protective function, drag-line gag lever post is cancelled, and overload limited block 3 is arranged on drag-line connecting screw rod 7.On drag-line connecting screw rod, be provided with thin neck A-A or B-B, the long-pending size of thin throat area is calculated through strict, once drag-line internal force surpasses design load, thin neck A-A or B-B place are pulled off, and maintain the safe handling of curtain wall by the elastic force of spring 4.
