APPARATUS FOR INTRODUCING COMPRESSIVE FORCE IN FABRICATED STEEL-FRAME TRUSS BRIDGE AND METHOD FOR INTRODUCING COMPRESSIVE FORCE USING THE APPARATUS

摘要

Harbour or hypothetical event of the present invention are tied jail with a prefabricated steel and make to assume that tempering introduces that the compression device one that is installed in and is distributed evenly in the lower theory of prefabricated steel truss-type bridges is ginjangryeok small to be related to a kind of method for being used for upstream and introducing the compression of prefabricated steel truss-type bridges by the way that a pulling force to be applied to PS at this by creating to be constructed on the device that is mounted on a prefabricated steel truss-type bridges using steel or I-beam gyojwa of a steel truss structure. ;Interconnection of the prefabricated steel truss-type bridges with a upper mold and at regular intervals passes through the installation that steel truss structure a pair of upper and lower mould is installed between lower mold sajae, a wherein crossbeam a pair of by using interconnection, steel truss structure is mounted, a pair of of steel truss sajae is installed in the sum in bridge structure and road surface by will meet the road surface road surface and soil of bridge from side the form or slab bokgongpan mono- that is connected to each other, it establishes as installation prefabricated steel truss-type bridges assuming that the old bridge harbour of installation or hypothesis on exhaust outlet arrive the installation of bridge;Compress access device,What prefabricated steel tied that firm theory casts anchor that lower between and lower mold is mounted on is again and again that depositing support support host brackets to each end installation crossbeam and lower mold in support bracket fastened installation host majority in both sides,So that triangle has difference in terms of the part to cross one another,Wherein each secondary seal,Installation,But the mounting and fixing bracket for being installed in and installing in lower mold in pairs is cast anchor at regular intervals,Installation site includes a pair,It has each fixation bracket to host at regular intervals and is mounted on installation,It is casting anchor for multiple combined intervals that bird, which leaves prefabricated steel and ties the theory lower dead center of firm mould,,It is mounted on installation supplement between lower mold and fixed bracket,Bird, which combines, supports the lower tensioning of the fixed bracket of secondary seal to connect with installation supporting element,But bird, which combines the support bracket fastened installation position of secondary seal to be installed in secondary seal and fix bracket, to be installed in the firm theory of middle prefabricated steel bundle in center inside.
