  However, the joists with mounting hardware as described above can only be used for hollow joists due to the characteristics of the hardware. For building construction, for example, pipes may be cut on-site for installation of equipment piping, but in the case of hollow steel joists, processing on-site is difficult. Wooden joists are often used.

  In addition, fixing floor panels to beams requires consideration of floor level stability and floor impact sound. When floor panels are firmly fixed to beams, floor impact sounds worsen, while when floor strength is loosened, floor levels are reduced. There is a problem that is not stable.

  In view of the above-described problems, the present invention is a mounting hardware for fixing a floor panel having a joist or a floor panel having a joist attached to the lower surface side of a floor board, which can be easily attached to the beam in the field. It is an object to provide a joist, a floor panel with mounting hardware, and a mounting hardware.

The above problem is the joist with the mounting hardware to attach the joist to the beam,
Mounting hardware is
A metal body that is arranged on the lower surface side of the joist and puts the beam in the vertical direction in cooperation with the joist,
Fixing material fixed to joists,
It can be operated from below the joist by connecting the hardware body and the fixing material, and it has a drawing shaft that draws the hardware body and the fixing material and integrates the hardware body and the fixing material.
Solved by joists with mounting hardware, wherein the hardware main body and the fixing material are in a temporarily fixed state in which the fixing material is not integrated, and the metal main body can rotate with respect to the fixing material with the pulling shaft as a rotation axis. .

  In the joist with the mounting hardware, the hardware main body can be rotated with the pulling shaft as the rotation shaft with respect to the fixing material in a temporarily fixed state where the hardware main body and the fixing material are not integrated. After the support is attached to the beam, the main body is fixed to the fixed material by simply rotating it around the beam using the pulling shaft as a rotation axis and pulling the main body and the fixing material together with the pulling shaft. The state is formed and the joist is attached to the beam, so that the joist can be easily attached to the beam in the field.

  In particular, fixing to the beam is realized by a hardware body and a fixing material attached to the joists, so the type of joists is not limited, and steel joists of internal cavities may be used, or solid wooden joists It can be fixed to the joists and beams that depend on the cross-sectional shape of the joists.

  Further, in the joist with the mounting hardware described above, the hardware main body is provided with a locking portion that restricts the rotation of the hardware main body and the fixing material with respect to the fixing material of the hardware main body as the rotation shaft when the hardware main body and the fixing material are attracted. It is good to have.

  In this case, since the locking part for restricting the rotation of the hardware is provided in the hardware body, after the joist is supported on the beam, the hardware body is rotated with respect to the fixed material and the shaft is used as the rotation shaft. When moving and moving under the beam and pulling the hardware main body and the fixing material with the pulling shaft material, it can prevent the hardware main body from rotating freely and prevent the position of the hardware main body from being fixed. The operator pulls the fixing material and the hardware main body from the lower side of the joist and pulls the fixing material and the hardware main body, without having to support it separately by hand to position the metal under the beam. Can be integrated.

  In addition, in a temporarily fixed state where the hardware main body and the fixing material are not integrated, the hardware main body may be movable in the joist length direction with respect to the fixing material.

  Since the hardware main body can move in the joist length direction with respect to the fixed material, the positional relationship between the joist with the mounting hardware and the beam can be adjusted in the joist length direction, so the beam and joist Even when the relationships are mixed, it is not necessary to prepare a plurality of joists with mounting hardware according to the relationship between the beams and joists, and it is possible to advantageously realize the material management and productivity.

  In addition, the above-described problem is similarly solved by a floor panel with an attachment hardware in which the joist with the attachment hardware is attached to the lower surface side of the floor board and an attachment hardware used for the joist with the attachment hardware.
