Abstract: The present invention relates to a prestress measuring method for measuring prestress applied to tendons with high reliability by precisely measuring the transversal strain of a mounting plate, that is the amount transversely strained when the mounting plate is pushed by pressing force applied by the mounting of the tendons in a mounting device on which the end of the tendons is mounted, and a tendon mounting device used in the prestress measuring method. The tendon mounting device comprises the mounting plate (10) with a predetermined thickness on which the tendons are mounted; and an expandable strain measuring member (2) formed of a band-shaped member for surrounding the lateral edge of the mounting plate (10), and having a strain sensor (20) for measuring the transversal strain of the mounting plate generated in the lateral direction of the mounting plate (10) while the mounting plate (10) is pushed by the pressing force of the tendons. The present invention can measure the transversal strain of the mounting plate (10) due to the prestress applied to the mounting plate (10) when the tendons are mounted, and can measures the prestress of the tendons based on the measured transversal strain and Poisson′s ratio of the mounting plate (10).

Abstract: The present invention relates to a method for forming the connection surface of a fiber reinforced concrete member using a perforated plate and, more specifically when a fiber reinforced concrete member is manufactured by using concrete contained with fiber, such as ultra high performance concrete, to a method for forming a perforated plate which is installed in a mold in order to form a fiber exposure connection surface that a fiber is exposed on the surfaces connected in one direction or the surfaces facing each other so as to connect fiber reinforced concrete members and to form a fiber exposure connection surface in a fiber reinforced concrete member by using the perforated plate. To achieve the above purpose, the present invention provides a method for forming a fiber exposure connection surface in a fiber reinforced concrete member by including the following steps: forming a fiber reinforced concrete pouring space by installing a perforated plate which is temporarily fixed to one side of a fiber reinforced concrete pouring space and on which through holes which allow a first surface corresponding to the fiber reinforced concrete pouring space and a second surface which is the opposite surface to the first surface to be communicated are formed; pouring fiber reinforced concrete in the pouring space; curing the concrete in a state where the fibers contained in the fiber reinforced concrete are located in the through holes while fiber reinforced concrete milk is discharged through the through holes formed on the perforated plate; and releasing the perforated plate in the fiber reinforced concrete member so that fibers with a through hole shape are exposed on the connection surface of the fiber reinforce concrete member.

Abstract: PURPOSE: A simultaneous manufacturing apparatus of a pair of U-shaped section pretension prestressed concrete members using inversion arrangement of a tendon is provided to save construction costs of a casting bed by converting an external force applying to a reaction frame into a structurally advantageous direction. CONSTITUTION: A simultaneous manufacturing apparatus of a pair of U-shaped section pretension prestressed concrete members using inversion arrangement of a tendon comprises a pair of end seating reaction frames (100), multiple inflection point reaction frames (110), and a conduction prevention auxiliary member (115). The pair of end seating reaction frames are separated from each other, installed on the ground surface vertically, and includes an upper penetration hole and a lower penetration hole. Both ends of a second tendon (10b) which is placed on an upper U-shaped concrete beam penetrate the upper penetration hole. Both ends of a first tendon (10a) which is placed on a lower U-shaped concrete beam penetrate the lower penetration hole. The multiple inflection point reaction frames are vertically installed on inflection points where the shapes of the first and the second tendons change, between the pair of end seating reaction frames. The multiple inflection point reaction frames are pressurized when the first and the second tendons are tensed, bending the first and the second tendons. The conduction prevention auxiliary member is installed in between the inflection point reaction frame and a supporting pavement face (200) in order to position the inflection point reaction frame to vertically float in the air.
