Abstract
The utility model discloses a connecting part of a prestress loading device. The connecting part comprises a loading base, a nut, a screw rod and a screw rod base, wherein a groove for holding a jack is formed on the loading base; a screw rod inserting hole is formed on one side of the groove; the loading base is provided with a connecting flange A on an opposite side of the screw rod inserting hole; one end of the screw rod is inserted in the screw rod inserting hole, and the other end of the screw rod is fixedly connected to the screw rod base; the screw rod base is provided with a connecting flange B on an opposite side of the connecting screw rod; the nut which is propped against the loading base is in threaded connection to a part outside the screw rod inserting hole of the screw rod. By adopting the technical scheme, prestress is applied to the entire supporting structure, and integral strength of the supporting structure is enhanced. The connecting part is convenient to detach and mount and can be recycled for several times, thus achieving the purposes of saving construction cost and facilitating construction.
Description
Technical field
The utility model relates to technical field of civil engineering, relates in particular to a kind of link 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 link of prestressing force charger, 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 link of prestressing force charger, comprise and load 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, load seat and be provided with adpting flange A at the offside of screw rod jack, one end of screw rod is plugged in screw rod jack, 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, after jack pressure release, can take off from link, by link, maintain and apply 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.
