Description
Technical field
The utility model relates to electric power water conservancy construction vertical shaft slide model lifting means, and a kind of vertical shaft steel strand jack particularly during deep shaft plain concrete sliding formwork hangs slip-form lifting device.
Background technology
In electric power water conservancy construction, vertical shaft concrete slip-form is absolutely necessary, and current vertical shaft concrete slip-form generally adopts supporting rod-type sliding formwork, and sliding formwork die body is sliding along cramp bar.Cramp bar is divided into Ф 25mm round steel and Ф 48mm steel pipe two kinds.In the lower end Transducers Embedded in Concrete of cramp bar, upper end is passed in feed-through hydraulic jack, sliding formwork die body is delivered to all vertical loads on cramp bar by feed-through hydraulic jack, complete the upwards sliding of sliding formwork die body, it is large to there is cramp bar steel consumption in supporting rod-type sliding formwork, easy unstability, joint complex process, supporting capacity is low, easily phantom offsets is caused when sliding formwork is out-of-level, the steel strand jack base position limitation setting height(from bottom) of internal layer horizontal reinforcement and the installation quality of internal layer horizontal reinforcement are not easy to check, control, supporting rod-type lifting jack for sliding stressing conditions cannot be monitored, die body and jack design are by defects such as experiences substantially.Therefore imperative to the improvement and bring new ideas of vertical shaft slide model lifting appliance.
Summary of the invention
For above-mentioned situation, for overcoming the defect of prior art, the object of the utility model is just to provide a kind of vertical shaft steel strand jack and hangs slip-form lifting device, effectively can solve vertical shaft concrete slip-form Upgrade Problem.
The technical scheme that the utility model solves is that comprise sliding formwork die body, steel strand, ground tackle and i iron brace summer, steel strand lower end is fixed on the junction plate of steel by ground tackle, and junction plate and sliding formwork die body are welded to connect; Steel strand upper end is passed in the steel strand jack being placed in well head, be engaged fixing with the intermediate plate in steel strand jack, steel strand jack is bolted on the i iron brace summer of well head, i iron brace summer two end supports is on column beam, column beam is by earth anchorage on Shaft bank platform, and steel strand jack is connected with the hydraulic control station be placed in above Shaft bank platform by high-pressure oil pipe; Steel strand, sliding formwork die body, ground tackle, i iron brace summer and steel strand jack form steel strand and hang sliding formwork upwards lift structure.
The utility model structure is simple, and novel unique, easily generate, steel strand reusability is high, and cost is low, and result of use is good.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Fig. 2 is A-A direction view of the present utility model.
Fig. 3 is B-B direction view of the present utility model.
Detailed description of the invention
Below in conjunction with accompanying drawing, detailed description of the invention of the present utility model is elaborated.
As shown in Figure 1, the utility model comprises sliding formwork die body, steel strand, ground tackle and i iron brace summer, and steel strand 1 lower end is fixed on the junction plate 4 of steel by ground tackle 3, and junction plate 4 and sliding formwork die body 2 are welded to connect; Steel strand 1 upper end is passed in the steel strand jack 5 being placed in well head, be engaged fixing with the intermediate plate in steel strand jack, steel strand jack 5 is fixed on the i iron brace summer 6 of well head by bolt 9, i iron brace summer 6 two end supports is on column beam 13, column beam 13 is fixed on Shaft bank platform by earth anchor 14, steel strand jack 5 is connected with the hydraulic control station 7 be placed in above Shaft bank platform by high-pressure oil pipe 8, hydraulic control station 7 by high-pressure oil pipe 8 for steel strand jack 5 provides lifting power; Steel strand 1, sliding formwork die body 2, ground tackle 3, i iron brace summer 6 form steel strand with steel strand jack 5 and hang sliding formwork upwards lift structure.
In order to ensure result of use, described steel strand jack, high-pressure oil pipe and hydraulic control station form hydraulic lifting system.
Described sliding formwork die body 2 is that bracing members beam 11 welds together the integrated steel-structure of formation with steel form 10;
Described steel strand 1 for diameter be 15.2mm, tensile strength is the steel strand of 1860MPa.
It is square that described junction plate 4 is made for δ 16 steel plate, is fixedly welded on sliding formwork die body.
Described i iron brace summer 6 is made up of 2 I 25 i iron.
Described column beam 13 is the multiple truss beam that ∟ 80 angle steel is welded into.
Described earth anchor 14 is 25mm reinforcing bar.
When the utility model uses, the steel form of sliding formwork die body is placed on vertical shaft inwall 12 Concrete Design position, when sliding formwork die body needs to promote, by being arranged in the hydraulic control station of Shaft bank by the oil cylinder fuel feeding of high-pressure oil feed oil pipe to steel strand jack piston bottom, hydraulic oil extrusion oil cylinder piston in hydraulic jack drives steel strand to move up by the lower anchoring clamping piece of steel strand jack, steel strand drive sliding formwork die body to move up by the ground tackle of lower end, thus complete the once lifting of sliding formwork die body, after sliding formwork die body has once promoted, high pressure oil return oil pipe is passed through to fuel feeding in the oil cylinder on steel strand jack piston top in hydraulic control station, the piston of steel strand jack resets under the effect of hydraulic oil, the reciprocal fuel feeding in hydraulic control station, oil return can realize the sliding continuously of sliding formwork die body by steel strand, during the fuel feeding of hydraulic control station, the upper anchoring clamping piece of steel strand jack is in releasing orientation, lower anchoring clamping piece removes in locking state, during the oil return of hydraulic control station, the lower anchoring clamping piece of steel strand jack is in releasing orientation, upper anchoring clamping piece removes in locking state.Due to much larger than the tensile strength of cramp bar connector of the tensile strength of steel strand, 15.2mm steel strand design ultimate bearing capacity is 10t, every meter of deadweight 1.1kg, 48*3.5mm steel pipe cramp bar design ultimate bearing capacity is 5t, every meter of deadweight 3.85kg, equal hoisting power, steel strand promote material 86% than cramp bar saving, steel strand installation rate is fast, lightweight, non junction, can repeatedly reuse, and saves production cost more than 50%.Because steel strand are anchored in the sliding formwork die body portion outside shaft wall Concrete Design sideline, the colligation of internal layer reinforcing bar, highly not by the restriction of sliding formwork die body structure, substantially increases the efficiency of reinforcing bar binding.Because steel strand keep vertical applied force always, effectively overcome the Rotation of sliding formwork die body, substantially increase the construction precision of sliding formwork die body.By installing steel strand stressometer on steel strand anchorage, effectively can read the stressed size of every root steel strand when sliding formwork promotes, according to the analysis to the stressed size of steel strand, the design of sliding formwork die body can be optimized further.The utility model structure is simple, and novel unique, easily generate, cost is low, is the innovation on vertical shaft slide model lifting means.
