METHOD OF CONSTRUCTION WORK USING FLUID STRUCTURAL MATERIAL AND STUD FOR USE THEREOF

摘要

PROBLEM TO BE SOLVED: To enhance the bonding strength of a fluid structural material such as concrete to a surface to be constructed in construction work which includes placing the structural material onto the surface and hardening it. SOLUTION: Studs 5 with each stopper portion 5b are driven at an appropriate density into the surface to be constructed (e.g. damaged surface of a Hume pipe 1), and then the fluid structural material is placed and hardened. Because a base layer 2 and a construction layer (repair layer in the case of the Hume pipe 1) 6 are linked together by the studs 5, the adhesive property of the construction layer 6 to the base layer 2 can be markedly enhanced.
