摘要： PURPOSE:To eliminate the need for connection work which connects two precast concrete boards as a form and further reduce reinforcing bar arrangement work as well on a construction site in terms of underground beam construction method installed in a foundation area of a building. CONSTITUTION:Two precast concrete boards 15 are connected to each other with spacing holding reinforcing bars 13 in a shop, thus keeping a specified spacing. Vertical reinforcing bars 11A, which constitute a vertical portion of stirrup bars 11, are also buried. U type reinforcing bars 11B on permanent concrete already cast and the vertical reinforcing bars 11a constitute lap slices on a site. U-type reinforcing bars 11c which constitute the upper end of the stirrup bars 11 and upper main reinforcing bars 9 are framed preliminarily and they are covered from above so that the U type reinforcing bars 11C and the vertical reinforcing bars 11A constitute lap slices.

摘要： PROBLEM TO BE SOLVED: To secure sufficient flexural bearing force, to restrain depth of girder and to correspond even to the case when there is floor height restriction by fastening fiber members on both end parts of a beam member while giving tensile force to the fiber member arranged progressively downward along the lengthy direction of the beam member while being engaged with a wooden structural member between the wooden structural members. SOLUTION: Wooden structural members 21 are arranged in parallel with intervals between them in the cross direction of a beam member 20 at a central part position 22 of the wooden beam member 20 and connected by a plural number of connecting hardwires 23, 23, and wooden intermediate materials 25, 25 are interposed between the wooden structural members 21, 21 between both end part positions 24, 24. A fiber member 30 is engaged by the connecting fitting 23 from below at the central part position 22 of the beam member 20, and the fiber member 30 is arranged protrusively downward along the lengthy direction of the beam member 20 through the wooden intermediate material 25 at the both end part positions 24 of the beam member 20. When both end parts 31, 31 of the fiber member 30 are pulled outward, vertically upward suspending force works on the connecting haidwares 23, 23, and tensile force is applied on the fiber member 30. Consequently, it is possible to secure sufficient flexural beam bearing force against a load in the vertically downward direction and to efficiently used a space by restraining depth of girder.

摘要： PROBLEM TO BE SOLVED: To provide a Joining method, in which the generation of the shear fracture of a woody material as a base material is prevented while separation generated on the interface of a grout material and the woody material is reduced and which can resist the extraction load of a joining member effectively when the woody material is joined through the joining member. SOLUTION: In the joining method of a woody material, the woody material 1 is divided into split pieces 10, recessed grooves are excavated to these split surfaces 10a while deformed steel pipes 5 having a shape engaged with the irregularities of the recessed grooves are disposed into the recessed grooves while the split pieces 10 are laminated. The insides of the deformed steel pipes 5 are filled with a filling solidifying agent and the agent is solidified, reinforcing bars 4 inserted into the deformed steel pipes 5 are fixed, and the woody material 1 is joined with other members through the reinforcing bars 4.
