摘要： PURPOSE:To reveal desired strength by arranging accurately a fiber, by a method wherein a hydraulic material is cast within a concrete shuttering, a continuing fiber is arranged or the hydraulic material is cast on the top of the same after vacuum dehydration, the vacuum dehydration is performed after arrangement of the continuous fiber, over which the hydraulic material is cast. CONSTITUTION:Connecting pipe 2 with a vacuum pump is continued to a side wall 1a of a vacuum box 1 in a closed state, dehydrating holes 3 are formed into a top plate 1b at fixed pitches and cotton cloth 4 is laid on the top of the same. A concrete shuttering 5 is put on the top of the top plate 1b and mortar 6d for the first layer is cast by a fixed quantity within the concrete shuttering. Then a continuing fiber 7a for reinforcement formed in a meshed state is laid on its top, vacuum dehydration is performed, the continuing fiber 7a is sucked and positioned to the top and a stationary layer is formed. This operation is repeated according to necessary strength of a fiber reinforced cement plate, the mortar 6c is cast finally by a fixed quantity and the vacuum dehydration is performed. In other words, the subject method may be constituted so that the mortar is cast within the concrete shuttering, stationary layer is formed by performing the vacuum dehydration and cast the next mortar within the concrete shuttering.

摘要： PURPOSE:To obtain a carbon fiber for cement reinforcement, having excellent adhesivity to cement, smoothly passing through a direct spray gun, having excellent collectability and suitable for direct spray process. CONSTITUTION:This carbon fiber for cement reinforcement is produced by coating the surface of a carbon fiber with a polyoxyalkylene bisphenol ether as a sizing agent. A composite cement material having a flexural strength of >=300kgf/cm is produced by cutting the carbon fiber to 10-50mm long and mixing to a cement matrix at a volume ratio of 1-5%.

摘要： PROBLEM TO BE SOLVED: To make it possible to connect a block-type perforated pipe and a single pipe arrangement type perforated pipe by fixing a connecting pipe to each inserting hole provided at the other end of a coupling body respectively and causing them to communicate, and connecting each connecting pipe projecting at the other end of the coupling body to each single pipe of a single pipe arrangement type perforated pipe respectively. SOLUTION: One end of a coupling body 1 is a female connecting end 3 to be connected to the male connecting end of a block-type perforated pipe, and a reinforcing ring 4 is fitted and fixed to its peripheral surface, and a recession 5 into which a block-type perforated pipe is inserted is formed concentrically at its end surface. In the opening end of each inserting hole 2 provided at the other end of the coupling body 1, one end of a connecting pipe 6 having a circular cross section is inserted and fixed respectively, is caused to communicate to the opening end of each inserting hole 2 respectively and is arranged in parallel with the axis of the coupling body 1. This connecting pipe 6 is connectable to each single pipe of a single pipe arrangement type perforated pipe respectively, by making its diameter and interval the same as each single pipe of the single pipe arrangement type perforated pipe. Accordingly, it is possible to connect the block-type perforated pipe to the single pipe arrangement type perforated pipe.
