摘要： PROBLEM TO BE SOLVED: To provide a flat deck preceeding construction method in steel frame reinforced concrete(SRC) construction capable of promoting execution efficiency and safety and preventing the partial loss of sectional area in the skeleton of a structure. SOLUTION: A joint metal fixture B equipped with a beam bar interlocking section on the front end is fixed to the end of a flat deck A with a bolt, and after the arrangement of beam bar 6, the beam bar interlocking section 1 of the joint metal fixture B is interlocked with the beam bar 6 to construct the flat deck A before a beam form is installed. The joint metal fixture B is so constituted that a beam bar interlocking hook section is bent to the front end of a plate having a flat deck joint bolt insertion groove hole, and a flat deck joint bolt head fitting recess section is provided to the rear side of the end of the flat deck A.

摘要： PURPOSE: To nondestructively measure water content by obtaining the relation ship between the water content and the thermal conductivity of a reference sample concrete which has the same material and blend as those of body con crete according to predictable temperature conditions in advance and obtaining the thermal conductivity of the body concrete using the twin comparison method. CONSTITUTION: Measurement sample side probes 7 and 8 measure the temperature of a body concrete 13 and reference sample side probes 9 and 10 measure that of a reference sample 14. The probes 7 and 9 are provided with a heater and a thermocouple and the probes 7 and 8 are provided with only a thermocouple, thus individually measuring the sample temperature at a part which is not affected by a thermal source and heating in a sample and hence obtaining the temperature difference between the both. A body 5 receives the temperature information of the probe, transmits an interface 6 for sending the information to the body 5 and a command for supplying heat, and further receives such information as a voltage related to the temperature change of the probe, thus obtaining thermal conductivity. A corresponding water content is obtained from the relationship curve between thermal conductivity and water content.
