摘要： PURPOSE:To prevent a foreign matter from interposing into an inner circumferential surface by eliminating wavy unevenness of the surface by a method wherein concrete is placed within a concrete form by setting a leverlike body to an arrangement position of a reinforcing steel material and the leverlike body is pulled out under a state where the concrete is not solidified. CONSTITUTION:A leverlike body 2 as a concrete form for molding of a sheath part for piercing through a main line of a pillar constituted of a steel pipe possessing a form corresponding to a section of the same sheath is set up to the sheath part in the concrete form 1 for manufacture of a precast concrete pillar member. Then after arrangement of necessary reinforcing iron rods such as reinforcing hoop iron rods have been performed, concrete 4 is placed within the concrete frame 1, the leverlike body 2 is pulled out under a state where the same placed concrete 4 is not solidified and the sheath part is molded. Accuracy of the sheath part can be secured without performing a displacement or a deformation through external force at the time of placement of the concrete, by constituting the leverlike body of a member possessing sufficient strength.

摘要： PROBLEM TO BE SOLVED: To provide a panel-joining method that is simple for execution and requires less time and labor for installing a structural heat-insulating panel without allowing heat insulation effect to decline. SOLUTION: On joining structural heat-insulating panels SIP in butting against each other at their ends, a splicing wood 3 is applied from the outside to the surface member 1 at least at one side of the surface and the undersurface of the panel, extending along the entire length of the butt-joining part, and joined by nailing with nails 4. With the splicing wood 3 exposed intentionally to the outside of the SIP panels, cutting is not required for the heat-insulating materials while preventing decline of heat insulation effect and execution of work can be simplified.

摘要： PURPOSE: To facilitate the execution of works, in which frost heaving generated on a foundation ground is prevented, by dividing the whole slope underfloor structure into a plurality of pairs of laminated structures, in which a plane shape is formed in a polygon. CONSTITUTION: The whole slope underfloor structure of an artificial skiing ground utilizing a slope land is divided and formed into a plurality of pairs consisting of the laminated structures A of polygonal planes. Upper structure, in which metal plates are mounted on top faces and which is composed of a heat-insulating material, and lower structure made up of metal plates or precast concrete boards and posts are combined integrally. Consequently, sections transmitting cold heat are decreased, thus effectively inhibiting frost heaving. Accordingly, a slope sectional shape can be formed freely without being subject to the effect of the irregularities of a ground surface while an expansion joint for obviating thermal shrinkage need not be fitted particularly, thus shortening the term of works.

摘要： PURPOSE:To make it possible to execute construction work under no influence of weather conditions and simplify facilitate required to lift up and enhance the efficiency of executing construction work with safety and high accuracy by inhibiting the weight of members required to lift up. CONSTITUTION:Panels 1A and 1B are constructed on both opposed sides of a set of core members. Then, an arch 2A, which is a beam located in the uppermost beam floor, is field-preassembled for every one span or spans. After a roof 3A is mounted thereto, a post 4A is suspended to the arch 2A while the roof 3A-mounted arch 2A is being lifted up at the uppermost parts of the panels 1A and 1B. The arch 2A is fixed with the uppermost area of the panels 1A and 1B at a specified position.

摘要： PURPOSE:To reduce a cost and improve work executing ability by a method wherein a plurality of pipe bodies each containing an excavating means are vertically formed in parallel at intervals, a beam formed such that the adjoining pipe bodies are intercoupled through a steel plate is pushed in a ground and erected between piles. CONSTITUTION:A pile 1 is vertically built and a groove is formed in a head part. An upper pipe and a lower pipe, both being a two-end open type, are intercoupled through a beam 3, a cutting edge is arranged to the tip part of the beam 3, and an excavating means is contained in each of the upper and lower pipes. The excavating means are horizontally pushed in a ground by a pusher and the beam 3 is inserted through the groove of the pile 1 for coupling. The beam 3 forms combination of a small steel pipe and a steel plate to minimize an amount of placed concrete and reduce a cost.

摘要： PURPOSE:To make light irregular reflection large and an image see able from any direction by making mist by injecting water and forming a thick object. CONSTITUTION:When a pump 3 is operated and the water injection is started from each water injecting nozzle 2 to upward, the water injected from each water injecting nozzle 2 becomes atomized by taking up the air around, and a thick planar screen A is formed. The static image or moving image is projected on the screen A from a projecting device 5. Since the method is to form the object which possesses the suitable thickness and wideness in mist condition by injecting the water, the air around is taken up and the light irregular reflection is large. Thus, the excellent image can be seen from any angle except from the projecting direction.

摘要： PURPOSE: To construct rigid connection by fitting beam main bodies onto a column joint face from respective clearances between vertical connection pieces of upper and lower columns, engaging tip locking projections in the adjacent beams with each other, and connecting the beam main bodies to the respective vertical connection pieces. CONSTITUTION: Respective beam main bodies 4 of four beams B are fitted in a joint space between upper and lower columns A from respective clearances between adjacent vertical connection pieces 1, 1 in each of the upper and lower columns A. Then, locking projections 3 in the respective beams B are diagonally engaged with each other in a gammadion shape, each of bolts C is passed through respective bolt holes 2, 5 in the adjacent vertical connection pieces 1, 1 and the beam main body 4 and fastened, and consequently, the beams B are connected to the columns A in a cross shape. In this way, without using any plate metal fitting or the like, rigidity of the column and the beam is increased while hardly deformed column-beam rigid connection for a rigid-framed bridge and the like can be constructed without any deterioration in wooden textures.
