摘要： PURPOSE:To make it possible to display high strength of a concrete paving slab even if it is thin in thickness by burying continuous PC steel materials, etc., arranged in two stages up and down from the central part of the thickness of the slab lengthwise of the concrete paving slab. CONSTITUTION:Continuous PC steel materials 3a and 3b of a high tensile reinforcing material are respectively buried in up and down sides from the central part of the thickness of a slab in two stages lengthwise to the inside of the concrete paving slab 2. Prefabricated bars 4a and 4b in the direction of the road width are in contact with both up and down PC steel materials to be arranged. Shrinkage due to dry shrinkage or temperature drop is constrained with the high tensile reinforcing materials, and the occurrence of cracks exceeding the allowable level is controlled. Economical concrete pavement without excessive increase in the thickness of the slab can be carried out by making lower side tensile force caused by traffic load and upper side tensile force caused by swelling of the paving slab occurring in the front and rear parts thereof resist against high tensile force materials.

摘要： PURPOSE:To prevent the sudden deformation of a concrete member in continuous lengths from being caused in a perpendicular directing by applying the component of vertical force, which is caused to the concrete member in continuous lengths by introducing prestress, to shock absorbing materials retained at fixed positions by fixing rods fixed on a floor surface and allowing the component of vertical force to be absorbed by the shock absorbing materials. CONSTITUTION:A beam press fitting 13 is inserted into a lateral clamp hole 12 corresponding to the bent portions of PC steel materials 11 in a concrete member 10 in continuous lengths and is allowed to protrude on both sides of the concrete member 10 in continuous lengths. Supporting frames 15 are fixed to the beam press fitting 13 with locking tools 14 and are positioned on both sides of the concrete member 10 in continuous lengths via packings 22. Shock absorbing members 24, each comprising a spring, rubber and a cylinder, are positioned on the upper surfaces of the top plates 18 of the supporting frames via sliding members 23 and are fixed to the to ends of fixing rods 25 fixed to a floor surface 27. Under such a condition,fixing anchors are removed to release the connection and fixing of the PC steel materials 11 to the floor surface 27 and the tractive tension of the PC steel materials 11 so as to allow prestress to be introduced.

摘要： PROBLEM TO BE SOLVED: To provide a method to produce a sound absorbing concrete plate having >=0.8 sound absorption rate for sound in 400 to 4000 Hz frequency region at a low cost. SOLUTION: (1) A porous concrete having 20 to 40% continuous porosity and 2 to 5 mm average diameter of vacancies is supplied in a mold frame having a rugged pattern in the bottom in such a manner that the supplied concrete has 50 to 80% thickness of the objective concrete plate. (2) A foamed resin member containing >=1.0 weight ratio of heavy oil to the foamed resin member is fixed to embed the upper face or a part of the porous concrete in such a manner that the projected area of the foamed member on the sound absorbing face is >=15% of the area of the face of the concrete.

摘要： PROBLEM TO BE SOLVED: To provide a sound absorbing concrete panel having a sound absorbing factor of not less than 0.8 for the sound in a frequency range of 400 to 4,000Hz. SOLUTION: A sound absorbing concrete board comprises a porous concrete panel having an irregular shape on the surface and an ordinary concrete panel on which the rear surface of the porous concrete panel is superimposed, and a partial air storing space is formed between the porous concrete panel and the ordinary concrete panel. In this case, the continuous void ratio of the porous concrete panel is 20 to 40%, the average void radius is 2 to 5mm, the thickness of the porous concrete panel is about 50 to 80% of that of the sound absorbing concrete panel, and the area of the stored space projected to the sound absorbing area is more than 10% relative to the sound absorbing area of the sound absorbing concrete panel.

摘要： PROBLEM TO BE SOLVED: To make it possible to perform the safe operation without dropping accident of the member to form a large-sized concrete member such as the girder of a bridge beam. SOLUTION: The form for a concrete member comprises a stretching member 15 which makes it possible to incline a pair of both side frames 13, 14 for forming both sides of a concrete member 11, and a planar moving element 30 for planely moving the member 15. The side rotating fulcrum 35 for rotatably placing at the side bearer 34 of the moving element is formed on the outer surface of the framed. The lower end rotary fulcrum 24 of the frames is immovably disposed at the lower end bearer 35 making it possible to place it. The lower fulcrum, the lower bearer and the side fulcrum, side bearer are temporarily simultaneously brought into contact with each other.

摘要： PURPOSE:To improve work performance at the time of installing a precast member and reduce the cost of material. CONSTITUTION:A base board 1 is provided with the lower part of an anchor member 2 burried therein, while a box body 5 which is provided with an engaging part 10 capable of joining the upper end part of the anchor member 2 with the bottom part 4a is burried so that the bottom part 4a is exposed. The opening of the box body 5 is set corresponding to the position where the anchor member 2 is burried, and the precast member 4 is made to slide to engage the upper end of the anchor member 2 with the engagement part 10 of the box body 5, and the box body 5 is filled with grout 11. It is thus possible to install and fix the precast member on the foundation board 1.
