CONSTRUCTION METHOD IN WHICH FRICTIONAL FORCE IS REDUCED BY CONTACT SURFACE FORMED BY SUPERPOSING TWO SHEETS OF POLYETHYLENE-1-HEXENE COPOLYMER

摘要

PROBLEM TO BE SOLVED: To provide a construction method in which impact force is inhibited and the damages of structures are suppressed because the structures start sliding by dynamic frictional force as a calculated value by multiplying the dynamic coefficient of friction of an α-polyethylene sheet bonded by normal force when the two polyethylene sheets are stuck fast and superposed and inserted to joint surfaces constituted by stacking the structures and external force applied to the structures under the state, in which the upper-lower structures are bonded with contact surfaces and load works in the external surfaces of the sheets is higher than the static frictional force of the contact surfaces of the sheets.

SOLUTION: The construction method is carried out so that the two α-polyethylene sheets having the low dynamic coefficient of friction are bonded with the smooth joint surfaces of the two structures, the contact surfaces, with which the sheets are fast stuck mutually, are formed and the structures start sliding by the dynamic frictional force of a theoretical value.
