LAP JOINT MECHANISM OF BURIED SHEET FOR CIVIL ENGINEERING

摘要

PROBLEM TO BE SOLVED: To provide the lap joint mechanism of a buried sheet for civil engineering, in which operation is facilitated and no rupture is also generated in a sheet joining section and which has stable structure having no possibility of the parting of mutual sheets even when a part of the sheet joining section is cut. ;SOLUTION: The side edges of the buried sheet 1 are superposed mutually, the projecting sections 21, 21... of a connecting hook bar 2 are penetrated and projected into the joint holes 11, 11... of the superposed side edge sections and joining is conducted by engaging an engaging piece 3 with these projecting sections 21, 21.... Accordingly, not only operation is facilitated and the term of works can be shortened and construction cost reduced because the buried sheets 1 can be connected mutually and simply but also the concentration of tensile force is lowered because tensile force is also dispersed and propagated from the contacting sections with the connecting hood bar 2 and the side end sections of the buried sheet 1 to the contacting sections with the connecting hook piece 3 and the side end sections of the buried sheets 1, and the lap joint mechanism of the buried sheets for civil engineering is stabilized structurally and extremely.;COPYRIGHT: (C)2000,JPO
