Description
Technical field
The present invention relates to technical field of civil engineering, particularly relate to a kind of steel strand support component 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, at present conventional method is: increase reinforced concrete fortifield village purlin in the street size, increase the quantity of steel pipe support, reduce spacing etc.But this will increase the consumption of constructional materials greatly, decrease effective construction space in foundation ditch.Due to the steel support structure adopted at present, mainly using single shaped steel or steel pipe as brace summer, effective connection is not formed between every root type steel or steel pipe, can not as combining structure work, so their support rigidity is lower, the power that can bear is relatively limited, for the foundation ditch that span is larger, adopts existing steel shotcrete support to be difficult to control its distortion.These support members are owing to being much all make by site operation requirement, there is no the connection dimension of specification, cannot reach between all parts and exchange and general object, after causing foundation pit construction to complete, most of support component all becomes expendable consumed product, can not reuse.
Summary of the invention
The present invention is directed to above-mentioned the deficiencies in the prior art, provide a kind of steel strand support component of pattern foundation pit supporting structure inner support system, easy accessibility, can repeatedly reuse, and reaches the object of saving construction cost, convenient construction.
Technical scheme of the present invention is achieved in that
The steel strand support component of pattern foundation pit supporting structure inner support system, comprise H profile steel, the lower surface of H profile steel is cross section and is welded with square floor, square floor has four flange holes, the upper surface of H profile steel is cross section and is welded with square connecting plate, stiffener is equipped with in the grooves on two sides of H profile steel, stiffener is vertical with the web of H profile steel and parallel with the wing plates on two sides of H profile steel, three limits of stiffener respectively with square floor, the web of square connecting plate and H profile steel is welded and fixed, the three pieces of guide strips be parallel to each other are welded with above square connecting plate, three pieces of guide strips are vertical with square connecting plate and corresponding up and down with the wing plates on two sides of stiffener and H profile steel respectively, two pieces of arch sheets are provided with between three pieces of guide strips, two arched sides of arch sheet are welded and fixed with the guide strip of both sides respectively, two bases of arch sheet and square connecting plate are welded and fixed, described guide strip is provided with several for the spacing jack plugging spacing pin above arch sheet.
The present invention is owing to have employed above technical scheme, be provided with standard size adpting flange, the top that prestressing force fish belly sill triangle encloses purlin can be assemblied in like this, as supporting base when prestressing force fish belly sill assembling steel strand, its circular arc arch sheet avoids the rigid friction of pedestal acute angle and steel strand, reduce the friction factor when stress application, extend the application life of steel strand.Arch sheet is provided with three pieces of guide strips, arc plate is divided into two pieces of regions (gathering sill), reduce vertically moving of steel strand, play restriction.Be provided with spacing jack on guide strip top, can pin be inserted after steel strand install, avoid steel strand to skid off in gathering sill.These parts are standard size parts, and easy accessibility can realize the matching requirements of plurality of specifications foundation ditch, can repeatedly reuse, and reach the object of saving construction cost.Using the inner support system that this cover standard component assembles out in a specific way, meeting in prestressed situation, larger construction space can be saved, convenient construction.The all parts being provided with the stiffener of lifting hole(eyelet), conveniently carrying, remove and install and enclose purlin parts is provided with the connection dimension of specification, reaches between all parts and exchanges and general object.
