    • PROBLEM TO BE SOLVED: To provide a paper drum for securing sufficient rigidity and bending strength at a shell and sufficient strength at a joint between the shell and a flange member.
      SOLUTION: The paper drum comprises an outer shell member 1 formed of a paper pipe material (a), an inner shell member 2 formed in a cylindrical shape by rounding a paper band sheet (b), and a pair of right and left flange members 3, 3 formed of paper discs (c). The inner shell member 2 has a plurality of engaging protruded pieces 5 provided at both axially right and left edges. The flange members 3 have insertion-through grooves 8 through which the engaging protruded pieces 5 of the inner shell member 2 are inserted, a plug-in groove 9 in which the front end 5a of the engaging protruded piece 5 is plugged after being turned around. The inner shell member 2 is internally fitted to the outer shell member 1, the engaging protruded pieces 5 of the inner shell member 2 are inserted through the insertion grooves 8 of the right ad left flange members 3, 3 from the inside to the outside, and the front ends 5a are turned around and plugged in the plug-in groove 9 from the outside to the inside and engaged therewith.

    • PROBLEM TO BE SOLVED: To provide a fireproof perforated panel excelling in fireproof performance using less adiabatic thermal expansion material.
      SOLUTION: The fireproof perforated panel 1 has a fireproof plate-like member 2 having a large number of through holes 5a penetrating the front and rear sides, and the adiabatic thermal expansion materials 3 provided around at least the through holes 5a of the fireproof plate-like member 2. When the adiabatic thermal expansion materials 3 are overheated, the adiabatic thermal expansion materials 3 are expanded to block the through holes 5a. One side face of the fireproof plate-like member 2 is formed with recesses 4 around the through holes 5a, and the recesses 4 are filled with the adiabatic thermal expansion materials 3. The adiabatic thermal expansion materials 3 are formed with through holes 5b penetrating the adiabatic thermal expansion materials 3 and communicating with the through holes 5a.
