Furring strip of roof foundation and earthquake-proof junction hardware of furring strip receiving intersection

摘要

Topic In order to prevent the fall of the roof, the seismic force operation to the roof facing the transmission possible junction hardware is offered to the muscle intersecting the top.SolutionsSteel sheet thickness disconnects the sheet of 2mm in six rectangularities. You open the bis hole of 4 places, the valley fold and the mountain fold do and with L shape of character structure, furring strip earthquake-proof junction hardware 1 for the left of the intersection of 4 and furring strip receiving 3 and dextral and 2 is completed. When strong seismic force increases, the rib of buckling prevention because the junction hardware that tries does not become deformed is provided. Because underneath the ceiling joist support 3 which is used generally at the interior, the furring strip the junction hardware which is accustomed to stopping 4 which it scrambles to orthogonal direction and the double furring strip firmly is necessary, bis doing to stop the junction hardware with tapping bis, 14 it locks.
