The utility model solves the technical scheme that its technical problem adopts: a kind of suspension cable conversion layer, described conversion layer comprises ground tackle, drag-line, stretch-draw adjuster, steering gear, backing plate etc.In described conversion layer concrete pouring construction process, pre-buried upper steering gear, by the time when described conversion layer concrete reaches design strength, the stretch-draw of presstressed reinforcing steel drag-line internal force is realized by the ground tackle stretch-draw of described stay cable end, described drag-line is through the arc sleeve of steering gear, to be sling by steering gear the beam slab of whole building structure, according to the difference of span, suspension cable conversion layer comprises two span continuous beam suspension cable conversion layers and three-span continuous beam suspension cable conversion layer two kinds design, according to the difference that drag-line is arranged, suspension cable conversion layer comprises uniaxially guy system and biaxially guy system two kinds layout, described suspension cable transferred floor design technology is a kind of novel building large span designing technique, more safer than conventional prestressed girder large span designing technique, construct more convenient.
The beneficial effects of the utility model are: the large span design that just can realize to light and flexible conversion layer, and have the advantage realizing building structure aseismatic, and the beam of drag-line to conversion layer is applied with favourable precompression simultaneously, and beam can be avoided to occur direct tension cracking.
On the basis of technique scheme, the utility model makes following expansion:
A kind of suspension cable conversion layer that the utility model proposes, described suspension cable conversion layer is applied to the design of building longspan structure.It is a kind of by floor as being a beam slab emptied, by the stretch-draw of drag-line, realize the large span design of conversion layer, because drag-line is distributed in the vertical plane of conversion layer axis, according to the structure design of suspension cable conversion layer, the enabling hole needs of conversion layer can not be affected.
Described suspension cable conversion layer utilizes floor plates to realize large span design, whole floor is regarded as a beam emptied, beam is non-prestressed continuous beam, according to the difference of span, comprise two across with three across two kinds of designs, when employing two across design time, two is equal across span, because story height is equal, so the internal force that drag-line can realize self offsets balance, when employing three is across design, two end bay spans are equal, middle span can free setting according to actual needs, the internal force that such drag-line also can realize self offsets balance, due to prestressed cable in use, along with the growth of service time, Relaxation of prestressing phenomenon is had inside drag-line, in order to eliminate Relaxation of prestressing phenomenon, in advance stretch-draw adjuster can be set in the middle of drag-line, the Main Function of stretch-draw adjuster is not used to dock prestressed cable, but pass through the rotation of stretch-draw adjuster screw shell, realize the docking stretch-draw of both sides prestressed cable, and then solve the problem of prestressed cable in use Relaxation of prestressing, drag-line is external prestressing steels, through the bottom hole of conversion layer intermediolateral column, to be sling by steering gear the beam slab of whole building structure, also the point load of whole frame column is namely held up by steering gear.
In the utility model one preferred embodiment, steering gear in described conversion layer structure adopts the material of high strength and low friction to make, it can be high-strength steel or for other Materials with High Strength, steering gear there is arc sleeve, according to the stretch-draw shape of drag-line, the corresponding arcuate shape formulating correspondence, to reduce the frictional force of drag-line in sleeve, during construction, drag-line, in advance through the arc sleeve of described steering gear, is held up at the bottom of the post of middle boxes trestle by the supporting plate of steering gear.
In the utility model one preferred embodiment, a supporting plate is arranged at steering gear bottom, supporting plate holds up at the bottom of the post of middle boxes trestle, and the benefit designed like this is that the structure design of whole Vierendeel girder only needs general mechanical model, and frame column still mainly bears the effect of axial pressure.
In the utility model one preferred embodiment, described ground tackle is the ground tackle of post stretching, the backing plate of ground tackle is embedded in concrete beam end, the stretch-draw being realized drag-line internal force by the post stretching ground tackle of end is regulated, the stretch-draw of drag-line adopts end stretch-draw, the benefit of such design is that the construction of Novel inclined drag-line conversion layer does not need special construction stretching machine, and the tensioning equipment existed in the market now just can directly use, and to construct feature more easily so suspension cable conversion layer has than conventional conversion layer.
In the utility model one preferred embodiment, stretch-draw adjuster can regulate the size of both sides drag-line power, realizes the effect eliminating drag-line Relaxation of prestressing.
In the utility model one preferred embodiment, described suspension cable conversion layer can be arranged as uniaxially guy system and biaxially guy system as required, so-called uniaxially guy system refers to the conversion layer only arranging suspension cable at an axis direction, described drag-line mutually combine be arranged in described conversion layer axis vertical plane on, there is out portal design the frame column bottom of pre-buried steering gear.
In the utility model one preferred embodiment, in suspension cable conversion layer pillar carry out and punch in advance and build process, in the process of construction, pre-plugged steering gear.
In the utility model one preferred embodiment, the portion of Vierendeel girder end office (EO) on conversion layer upper strata adopts haunch design, improve the intensity of beam-ends local, avoid end anchorage to destroy, ground tackle applies pressure to backing plate, and power is divided into the component of level and vertical both direction by backing plate, be applied to Vierendeel girder and frame column respectively, according to the size of component, Vierendeel girder and the corresponding increasing section of frame column amass, to bear corresponding pressure.
In the utility model one preferred embodiment, in three-span continuous beam suspension cable transferred floor design, in steering gear place, due to drag-line to steering gear make a concerted effort obliquely, in order to make frame column only be subject to the effect of vertical axis power, the beam at drag-line horizontal segment place takes deepened beam to design, and makes it to bear horizontal force action, we are referred to as deepened beam, are preset with the duct of interspersed drag-line when deepened beam is built.
