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.-

摘要： A building face material with printed indications is provided, where, even when any part of the building face material is cut in a cutting process in a manufacturing process, each first printed indication is marked at an allowable distance from an end side of the building face material that is rectangular in a plan view, and printed indications are preliminarily marked at predetermined intervals, in a given column.
The building face material 10 with printed indications includes printed indication strings each including one string group that is repeated in cycles, the string group being formed, in a plan view, on a rectangular flat face of the building face material, and the strip group consisting of multiple printed indications that are arranged, at regular first intervals, in a predetermined order along at least one straight line driven to a first side 11 or a second side 12 of a rectangle.-

摘要： A calcined gypsum treatment apparatus has an agitating type of cooler provided with a cooling region for cooling the calcined gypsum, and a moisture supplying device for incorporating moisture into the calcined gypsum. The moisture supplying device includes a humid gas-feeding port which introduces humid gas including moisture or steam, directly into the cooling region. The calcined gypsum is introduced through a calcined gypsum introduction port into the cooling region, and the moisture is incorporated into the calcined gypsum to modify the calcined gypsum. The humid gas-feeding port is positioned in vicinity to the calcined gypsum introduction port so as to allow the spouted or delivered flow of the humid gas to be brought into contact with the calcined gypsum immediately after introduced into the cooling region.

摘要： A multitubular rotary heat exchanger has a stationary shielding unit. The shielding unit is positioned in close proximity to a tube plate outside a heating or cooling region. A stationary surface of the shielding unit is positioned in opposition to and in close proximity to an end opening of a heat transfer tube moving in an upper zone of the heating or cooling region, thereby transiently reducing or restricting the flow rate of the thermal medium fluid flowing through the heat transfer tube moving in the upper zone.
