Claims

[Claims for Utility Model Registration] ■ A plurality of linear slits are inserted into a steel plate at predetermined intervals, parallel to each other, and the positions of the slits are matched in the direction perpendicular to the longitudinal force of the slits,
The plate portions between these slits are alternately bulged and deformed vertically to form a plurality of convex portions on both the upper and lower surfaces of the steel plate. A joint plate is then placed on the precast concrete slab in which the main reinforcing bars are buried, on the upper surface side. A PCa plate used in a construction method for synthetic floor slabs, etc., in which the convex portion is buried in a state of protruding from the upper surface of the precast concrete slab. ■ A request for registration of a utility model characterized in that the steel plate is an expanded metal made by inserting approximately V-shaped slits intermittently in the longitudinal force □ direction of the linear slits and elongating the steel plate. PCa slab used in the construction method of synthetic floor slabs etc. as described in Scope Item 0.
