摘要： PROBLEM TO BE SOLVED: To install a steel pipe beam by absorbing deflection and an installing error of the steel pipe beam, by fixing one side of a bending pipe to the end of a horizontal beam, arranging a small diameter part insertable into a column through a vertical steel pipe and a collar lockable in a prescribed depth on the other side, and filling cement milk in inside and outside clearances with the bending pipe to be inserted into a column top part. SOLUTION: A stud 1 is previously erected in a prescribed position by a concrete pipe, and the horizontal side of a hook shaped bending pipe 3 of its stud 1 is fixed to a horizontal beam. The horizontal side of its bending pipe 3 or an end part of a vertical steel pipe is formed as a small diameter pipe 3a easily insertable into the concrete pipe, and a collar 3b lockable on the concrete pipe edge is provided. When the small diameter pipe 3a on which its collar 3b is arranged is inserted into the stud 1, cement milk 4 is previously injected into the concrete pipe, and the small diameter pipe 3a is inserted up to the middle, and the cement milk 4 is also continuously injected, and a milk receiving plate is fixed to an inside surface of the concrete pipe in a position where a milk layer having a proper thickness can be formed. Therefore, a steel pipe beam can be installed by absorbing deflection and an installing error of the steel pipe beam.

摘要： PURPOSE:To obtain a heat insulating concrete plate which is excellent from view point of strength inspite of possession of necessary heat insulating capacity and possesses low water permeability, by a method wherein the opposite side of a heat insulating concrete layer wherein lightweight aggregate or bubbles are mixed in one face side thereof is formed into a densified concrete layer. CONSTITUTION:Concrete with which lightweight aggregate or a foaming agent is mixed is deposited within a concrete shuttering and the concrete shuttering is driven and turned so that centrifugal force is acted upon the same in the direction of its thickness. A densified concrete layer Cd is formed on an outer circumferential side of a diametral direction of a turning locus of the concrete shuttering, a heat insulating concrete lay Ci is formed on an inner circumferential side of the diametral direction of the turning locus and demolded after cure. The opposite side concrete layer to be integrated with a heat insulating concrete layer Ci with which the lightweight aggregate or bubbles are mixed is constituted into a densified one while giving desired heat insulating properties to the heat insulating concrete layer Ci, in a concrete plate obtained in this manner. With this constitution, along with an improvement of the whole strength of the concrete plate, infiltration of water or salt into the surface of the concrete layer Cd can be reduced.

摘要： PURPOSE:To obtain a corrosion-resistant pile having good bending resistance characteristics by a method in which at least six frame reinforcing bars extending to the longitudinal direction are buried in the peripheral layer of the inside concrete layer, and a synthetic resin outer layer is formed on the outside of the concrete layer. CONSTITUTION:At least six frame reinforcing bars 12 of a deformed bar steel are buried at an equal interval in the peripheral layer of the inside concrete layer 11, and a synthetic resin outer layer 10 of polyethylene resin, having a thickness of 2-3mm, is formed on the outside of the concrete layer 11. The corrosion of the bars 12 can thus be well-prevented by the protective action of the layer 10 even when the bars 12 are positioned near the peripheral side of the concrete layer 11. Also, since the bars 12 are positioned near the peripheral side of the layer 11, the bending resistance characteristics of the pile can be enhanced.

摘要： PURPOSE:To form a concrete pile having high bending strength at low cost by a method in which axial reinforcement bars of more than a specific number are contacted with the inner surface of an outer tube over the whole length of each axial reinforcement bar at equal intervals and buried with concrete layer by positioning them in an omnipresence manner toward the peripheral side. CONSTITUTION:Flat steel plates 12 as a kind of axial reinforcement material are set in 6-20 numbers, preferably 8-12 numbers, at equal intervals in the circumferential direction and fixed to a ring spring 13 to form an axial reinforcement bar cage 17. An outer tube 10 is fit on the outside of the cage 17, and ready-mixed concrete containing an expandible material is charged into the outer tube 10 and molded centrifugally. Since the axial reinforcement bars are positioned in an omniprence manner on the outermost side of the concrete layer 15, max. bending resistance effects can be obtained by using smallest number of axial reinforcement bars.

摘要： PURPOSE:To construct an enlarged bulb easily and certainly, by forming an enlarged dug-down section with water jet excavation after a bearing layer of a pile lower-end is excavated with a spiral auger, and by jetting cement milk. CONSTITUTION:A cylindrical pile 6 is set sunken by an internal digging method, and a spiral auger 1 for setting a reaming cutting-edge near the outer periphery of the auger is used, and to a desired depth from the lower end of the pile 6, a bearing layer is dug down almost in the same diameter as the outer diameter of the pile 6. Then, on the wall surface 5 of the dug-down section, the high pressure water 8 of the water pressure of 100kg/cm or higher is jetted through a nozzle 7 to form an enlarged re-dug-down section 9. Besides, with the jet pressure of 180kg/cm or higher, cement milk is jetted through the nozzle 7, and the spiral auger 1 is pulled upward and at the same time, an enlarged bulb is formed at the enlarged re-dug-down section 9.
