Description
Technical field
The utility model relates to technical field of civil engineering, relates in particular to a kind of prestressing force charger of pattern foundation pit supporting structure inner support system.
Background technology
In Soft Soil Foundation Pit engineering, steel concrete or steel pipe support supporting and protection structure, in order to reduce the distortion of foundation ditch, increase stability, and conventional method is at present: increase the reinforced concrete fortifield village purlin quantity of size, increase steel pipe support in the street, reduce spacing etc.But this will increase the consumption of constructional materials greatly, also reduced effective construction space in foundation ditch.Due to the steel support structure adopting at present, mainly using single shaped steel or steel pipe as brace summer, between every shaped steel or steel pipe, do not form effectively and connect, can not be as combining structure work, so their support rigidity is lower, the power can bear is relatively limited, for the larger foundation ditch of span, adopts existing steel shotcrete support to be difficult to control its distortion.These support members are owing to being all much to make by site operation requirement, the connection dimension that there is no standard, cannot reach between all parts and exchange and general object, after causing foundation pit construction to complete, most of support components all become expendable consumed product, can not reuse.
After at present conventional pattern foundation pit supporting structure completes, without prestress application technique, or increase support member, cannot after support system has been assembled, further improve the integral rigidity of support system.
Summary of the invention
The utility model, for above-mentioned the deficiencies in the prior art, provides a kind of prestressing force charger of pattern foundation pit supporting structure inner support system, for whole supporting and protection structure applies prestressing force, improves the bulk strength of support system.Easy accessibility, can repeatedly reuse, and reaches the object of saving construction cost, convenient construction.
The technical solution of the utility model is achieved in that
The prestressing force charger of pattern foundation pit supporting structure inner support system, comprise jack and link, described link comprises loading seat, nut, screw rod and screw rod base, loading seat is provided with for placing the groove of jack, one side of groove is screw rod jack, in screw rod jack, plug screw rod, load seat and be provided with adpting flange A at the offside of screw rod jack, in groove, place jack, the shore of jack inserts in screw rod jack and offsets with one end of screw rod, the other end of screw rod is fixedly connected with screw rod base, screw rod base is provided with adpting flange B at the offside of connecting screw rod, can with load nut thread that seat offset and be connected to beyond the screw rod jack of screw rod in part.
As preferably, described loading seat is provided with hanger, and hanger has lifting hole(eyelet).
As preferably, on described adpting flange A, have four flange holes, four flange holes are square four jiaos of distributions, and this foursquare length of side is 200mm.
As preferably, on described adpting flange B, have four flange holes, four flange holes are square four jiaos of distributions, and this foursquare length of side is 200mm.
As preferably, in the periphery of described nut, be fixed with a plurality of handles.
As preferably, the periphery of described screw rod base is provided with a plurality of reinforcing ribs, and reinforcing rib is connected with adpting flange B.
The utility model has been owing to having adopted above technical scheme, is mainly arranged on the angle brace of pattern foundation pit supporting structure inner support system, to supportting, and after support system has been assembled, for whole supporting and protection structure applies prestressing force, improves the bulk strength of support system.During use, standard flange by this charger by two ends is installed on the angle brace of inner support system or in support, while needing to load, use the jack pressurization lead-screw base in loader, while being loaded into design load, lock nut, completes loading, jack can take off from link after pressure release, by link, is maintained and is applied stable prestressing force.This link is standard size parts, and easy accessibility can be realized the matching requirements of plurality of specifications foundation ditch, can repeatedly reuse, and reaches the object of saving construction cost.The inner support system of using this cover standard component to assemble out with ad hoc fashion, meeting in prestressed situation, can save larger construction space, convenient construction.
