For example, the thickness is 1.2 mm, the outer shape is 100 mm, and the height is 300 mm. Various dimensions are available. In addition, L-shaped leg portions 14 are arranged radially at three locations outside the lower portion of the sleeve body 12, and through holes 14a are provided in the leg portions 14, so that they are placed at predetermined positions on a temporary frame temporarily installed during floor construction. The sleeve body 12 to be arranged can be temporarily fixed by nailing or the like.

  The pipe fixing mechanism 15 integrally provided on the upper portion of the main body sleeve 12 includes a mounting base 16, a pipe fixing member 18, and a U bolt 20. As shown in FIG. 3A, the mounting base 16 pierces one end of a rectangular steel plate having a predetermined thickness in a semicircular shape, and this piercing portion is flush with the upper end opening surface of the sleeve body 12. It is arranged so that it is fixed in a cantilever state by the welded portion 17 on the back side, and bolt through holes 22 through which bolts 40 for fixing the pipe fixing member 18 are passed are formed in two places on the outside. .

  The pipe fixing member 18 uses an angle material having an L-shaped cross section, and as shown in FIG. 3 (B), is mounted in a horizontal direction with a pipe support piece 24 positioned in the height direction and supporting the pipe. A mounting piece 26 to be placed on the table 16 is provided, and a pair of bolt through holes 34 (see FIGS. 4A and 5) through which the bolt portion of the U bolt 20 is passed through the pipe support piece 24 are formed. A pair of bolt through holes 28 are formed through which bolts 40 used for fixing the mounting base 12 are passed. Further, as shown in FIG. 5, the bolt through hole 34 provided in the pipe support piece 24 is a long hole in the lateral direction, and the U bolt 20 fitted in the bolt through hole 34 is laterally moved in the range of the long hole. Adjustable.

Thus, the position of the pipe fixing member 18 can be adjusted with respect to the mounting base 16 within the range of the long hole.

[Floor work using floor sleeves]
FIG. 6 is an explanatory view showing an assembly arrangement of floor sleeves in floor construction. As shown in FIG. 6, at the time of floor construction, a temporary frame 45 is constructed in the lower part of the floor surface (the top and bottom of the lower floor) with respect to the steel structure of the building (not shown), and a predetermined position that becomes water around the temporary frame 45 The floor sleeve 10 according to the present invention is disposed on the lower leg portion 14 of the sleeve body 12 and temporarily fixed by nailing. Subsequently, the reinforcing bars 46 are arranged and fixed to the reinforcing bars 46 in contact with the floor sleeve 10 by using a binding wire such as a wire.

  Here, as for the pipe fixing mechanism 15 provided integrally on the upper portion of the sleeve body 12, since the outer diameter of the pipe 50 passing through the sleeve body 12 is determined in advance, as shown in FIG. In a state where the pipe 50 is supported and fixed to the pipe fixing member 18 by the U bolt 20, the position of the pipe fixing member 18 is adjusted with respect to the mounting base 16 so that the center axis of the pipe 50 coincides with the center axis of the sleeve body 12. The pipe fixing member 18 is fastened and fixed to the mounting base 16 with bolts 40 and nuts 42. This is because the position of the pipe fixing member 18 cannot be adjusted in a state where the floor sleeve 10 is buried in the floor by concrete placement, so that the positioning is adjusted and fixed before the concrete placement.

  On the other hand, the U-bolt 20 may be prevented from being dropped by screwing the nut 38. Since the U bolt 20 is not used until the pipe is fixed, it may be detached from the floor sleeve 10 and attached during the pipe fixing work.

As shown in FIG. 9, when the pipe 50 is fixedly supported to the sleeve body 12 of the floor sleeve 10, the nut 38 of the U bolt 20 is loosened and widened, and the pipe 50 is arranged through the U bolt 20 and the sleeve body 12. When the positioning of the pipe 50 is completed, the nut 38 is screwed into the screw portion 36 of the U bolt 20, and the pipe 50 is fastened and fixed to the pipe fixing member 18 by the U bolt 20.

  In this case, the position of the pipe fixing member 18 is adjusted at the stage before placing concrete as shown in FIG. 7 so that the center axis of the pipe 50 substantially coincides with the center axis of the sleeve body 12 at the contact position of the pipe 50. For this reason, the U-bolt 20 is fastened and fixed to the pipe fixing member 18 so that the center axis of the pipe 50 is substantially aligned with the center axis of the sleeve main body 12, and the sleeve main body 12 and the pipe 50 are fixed. A uniform gap is formed between the two.

  Subsequently, a non-combustible material or a sealing material is pressed into the gap between the sleeve body 12 and the pipe 50 to close the gap.

  After constructing the floor by placing concrete in this way, the site work of installing the pipe fixing portion in the opening of the floor sleeve 10 is not required, and the floor sleeve 10 can be installed at the work site without requiring a welding device. Piping that passes through the sleeve main body in the height direction can be supported and fixed by the pipe fixing mechanism 15 integrally provided on the upper portion of the sleeve main body, so that the efficiency of the construction work can be greatly improved.

  In addition, although said embodiment took the floor sleeve which penetrates piping in the height direction of a building as an example, you may apply to the sleeve which penetrates piping in the horizontal direction or diagonal direction of a building.
