Title:
PRECAST CONCRETE MEMBER JOINING STRUCTURE
Document Type and Number:
Japanese Patent JP3958453
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide a precast concrete joining structure wherewith an embedded metal can be produced without welding a stud and a high accuracy can be ensured for execution of works without the need for embedment of a sleeve material for forming an insertion hole for high strength bolt.
SOLUTION: A joining steel plate 27 is caught from both sides with each of edge parts 21a of a pair of precast concrete members 21 each of which is divided into two in the direction of thickness, and the precast concrete members 21 facing each other are joined together by tightening a high strength bolt 29 which is pierced through the edge part 21a and the joining steel plate 27. In this case, a closed-end cylindrical embedding cap 23 is embedded at the edge part 21a of the precast concrete member 21. With the joining steel plate 27 caught between the bottoms 23a of the embedding caps 23 fastened tight with the high strength bolt 29, the edge parts 21a are stuck fast to the joining steel plate 27.
