T Tension adjustable prestress wide convex T girder and information service construction system of temporary facility structures that can predict and adjust external force using the same and construction method thereof

摘要

The present invention relates to a prestressed wide convex T girder capable of adjusting tension, an information construction system for a temporary structure capable of predicting and adjusting external force using the same, and a construction method thereof. made with PS steel material (PC steel bar or PC cable) with linearity, enabling horizontal or bending arrangement, fixing both ends of the PS steel material with fixed anchoring ends (dead ends), and then one reaction anchoring block part Tension and fixation using the action tension fixing part and the detachable hydraulic cylinder of the action tension fixing part make it possible to re-tension, attaching an electronic vibration sensor, and attaching a vernier caliper for direct visual confirmation (horizontal and vertical) ), and after installing the deflection reference line that can measure the girder deflection, the measurement is performed by hingedly connecting the reference wire at the point supported by the brace so that the reference line does not change when the girder is deformed, and the measurement result is calculated using the principle of fit and the equilibrium equation, etc. We provide a pre-stressed wide convex T-girder that can control tension that allows external forces such as earth pressure to be analyzed and future external forces such as earth pressure to be predicted through algorithm analysis, and an informatized construction system and construction method for temporary structures that can predict and adjust external forces using this. is in The present invention for achieving the above object is a girder body portion, and a first and second inner resistance portion configured to have a cross section smaller than the cross section of the girder body portion and extending in the longitudinal direction of the girder body portion from upper both ends of the girder body portion Wide convex T-girders made of internal parts; Doedoe coupled to the lower part of the first extensible part, positioned so as to be spaced apart from the girder body and bolted to the lower part of the first extensible part through a slot hole formed in the upper part so as to be able to slide in the longitudinal direction of the first extensible part by the length of the slot hole Reaction fixing block unit configured; PS steel material fixed so that one end is fixed to the reaction fixing block unit, and the other end is connected to the other end of the girder body unit; an action tension part installed to be interposed between the girder body part and the reaction fixing block part and for introducing a pre-stress to the T girder by pushing the reaction fixing block part so that the PS steel is tensioned; Prestressed wide-width convex T girder capable of adjusting tension, characterized in that it includes; and informatization capable of predicting and adjusting external force using the same; It makes the technical gist of the construction system.
