Upper beam or upper beam (2nd floor beam)
Via a rubber washer on the upper end of the reinforcing bar protruding from the upper surface of the
Screw on the nut while the bracing structure
Reinforced material is installed in a concrete foundation with elastic anchors.
-Screwed to the upper end of the anchor bolt that inserted and supported the body at the lower end
Brace structure which is screwed and connected to the upper part of
But for concrete foundation and upper girder or upper beam (2nd floor beam)
And can slide up and down.
