摘要： An object of the present invention is to provide a gypsum-based load-bearing board for wood structural load-bearing walls which is capable of increasing the co-efficient of effective wall length without additionally using reinforcement materials or stiffening materials, and without increasing the specific gravity and/or the thickness of the gypsum-based board. The gypsum-based load-bearing board (10) for wood structural load-bearing walls includes a main member or a core member formed from a board-shaped hardened gypsum containing an inorganic fiber and an organic-based strength enhancer that exert a lateral nail resistance of 500 N or more, and a paper covering at least front and back sides of the main member or the core member to constitute the load-bearing board. The load-bearing board has a surface density of 6.5 kg/m2 to 8.9 kg/m2, exhibits an ultimate displacement (δu2) of the load-bearing wall measured by an in-plane shear test of greater than 20×103 rad (δu2), and exerts an ultimate strength (correction value) (Pu′) of greater than 7.6 kN. According to the wooden structural load-bearing walls using the load-bearing board can obtain short-term reference shear strength (P0) greater than the wooden structural load-bearing walls using similar load-bearing board having a surface density of greater than 9.0 kg/m2.

摘要： A penetration part fireproof covering material used when a penetration part covered for fireproof is formed in a fireproof beam that is a fireproof constructional member that constitutes a wooden building, wherein the penetration part fireproof covering material is formed to have a tubular shape by stacking a plurality of gypsum board pieces (13a) formed from gypsum boards in a thickness direction and unitarily connecting the plurality of gypsum board pieces. The penetration part fireproof covering material is formed to have the tubular shape by stacking the plurality of gypsum board pieces that preferably have an annular shape and are cut out from commercially available gypsum boards having thicknesses of 9.5 mm to 25.5 mm while fixing the plurality of gypsum board pieces to each other preferably using metal fasteners such as staples, and unitarily connecting the plurality of gypsum board pieces.

摘要： An object of the invention is to prevent differences in the flow rate and the specific gravity of a gypsum slurry from being caused between slurry discharge ports, to divide a current of the slurry into streams without a factor of stagnation of the slurry provided at a branch part, and also, to ensure a sufficient distance between the discharge ports.
The slurry delivery conduit (10) has a rectilinear tube segment (14), a branch part (15) and branch tube segments (16). A tube-wall joint portion (20) of the branch tube segments configures a counter-flow splitting element (22) in a form of V-letter at the branch part. The slurry is introduced from a mixing area (51) into the rectilinear tube segment, which configures a straight rectilinear fluid passage. The rectilinear tube segment rectifies a flow of the slurry to be an axial or rectilinear current (S), and the axial or rectilinear current is split into branch streams (S1, S2) by the counter-flow splitting element.-
