Hereinafter, an embodiment of the present invention will be specifically described with reference to FIGS.
In the figure, reference numeral 1 denotes a floor received on a joist 2 of a wooden building, and an opening 3 for attaching an underfloor inspection port is formed on the floor 1. 4 is an outer frame having a rectangular (square or rectangular) planar shape made of aluminum, which is fitted into the opening 3 of the floor 1 and attached from above, and rises in four directions along the inner peripheral surface of the opening 3. A wall 5, a flange 6 that is connected to the upper end of the rising wall 5 at a right angle toward the outside and abuts against the upper surface of the floor 1 around the opening 3, and a right angle toward the inside in the middle of the rising wall 5. And a recess receiving portion 7 formed on the lower surface along the length of the outer frame so as to face inward from the lower end of the rising wall 5 and having engagement pieces 8a, 8a on both sides of the lower end. 8 and a lid reinforcing material receiving portion 9 formed so as to be flush with the engaging pieces 8a, 8a of the engaging recess 8 and projecting inward from the lid receiving portion 7 are integrally provided. The rising wall 5 of the outer frame 4 is formed with a step in the middle of which the upper half is located on the inner side of the lower half, with the lid receiving portion 7 being formed.

  The lid body 10 received by the lid body receiving portion 7 of the outer frame 4 has a lid plate 11 made of the same material as the floor 1 and a rectangular shape (square or rectangle) covering the outer periphery of the lid plate 11. And the inner frame 12. Similarly to the outer frame 4, the inner frame 12 is also made of aluminum. The inner frame 12 is continuously provided on the upper surface of the cover plate 11, and is connected to the upper ends of the four rising walls 13 and the upper ends of the rising walls 13. The lid body 10 is configured by fixing the screw 15 to the lid plate 11 at a position perpendicular to the outer peripheral surface of the lid plate 11 at the rising wall 13. A metal lid reinforcing member 16 is attached to the back surface of the lid plate 11 at a right angle to a pair of opposing sides of the lid plate 11. Reference numeral 17 denotes a handle for grasping when the lid 10 is opened and closed.

  By the way, the outer frame 4 is attached to the joist 2 via first and second synthetic resin outer frame attaching members 18 and 19. Specifically, the first outer frame mounting member 18 has a rectangular planar shape, and the upper end is fitted in the engagement recess 8 of the outer frame 4, and the engagement recess 8 is engaged on both sides of the upper end along the long side. Engagement pieces 18a, 18a that engage with the pieces 8a, 8a are provided so as to be movable in the length direction of the outer frame 4, and engagement pieces 18b, 18b are provided on both sides of the lower end on the short side. A recess 18c is provided on the lower surface. The upper end of the second outer frame attaching member 19 is fitted into the engaging recess 18c of the first outer frame attaching member 18, and the engaging pieces 18b, 18b of the first outer frame attaching member 18 are provided on both sides of the upper end. A fitting portion 19b having a groove 19a, 19a having an opening at one end and a closing at the other end for fitting is provided at the upper end, and a portion below the upper end serves as a mounting portion 19c for the joist 2 and The surface is formed in a flat shape, and a screw insertion hole 19d for screwing the second outer frame attachment member 19 to the joist 2 is formed in the vicinity of the lower end of the attachment portion 19c. Reference numeral 19e denotes a reinforcing rib of the attachment portion 19c. The joist 2 is present so as to correspond to the second outer frame attaching member 19 coupled to the lower part of the four outer frames 4.

  In the above configuration, the work sequence for supporting the outer frame 4 on the joist 2 is as follows. First, the upper end of the first outer frame mounting member 18 is fitted into the engaging recesses 8 on each side of the outer frame 4, and the engaging pieces are engaged. 18 a and 18 a are engaged with the engaging pieces 8 a and 8 a of the engaging recess 8. In this state, the upper end fitting portion 19b of the second outer frame attachment member 19 is fitted into the engagement recess 18c of each first outer frame attachment member 18, and the engagement pieces 18b, 18b of the first outer frame attachment member 18 are inserted. Is inserted into the grooves 19a, 19a. At this time, the lengths of the grooves 19a and 19a are set so that there is a margin so that the surface of the mounting portion 19c with respect to the joist 2 protrudes outward from substantially the lower half of the rising wall 5 of the outer frame 4. . In addition, in order to couple the first outer frame attaching member 18 to each side of the outer frame 4, the engagement pieces 8 a of the engagement recesses 8 on each side of the outer frame 4 are cut out at appropriate positions. The first outer frame attaching member 18 is fitted into the engaging recess 8 from the portion, and the first outer frame attaching member 18 is moved in the length direction of the outer frame 4 so that the engaging pieces 18a, 18a are engaged with the engaging recessed portion 8. The engagement pieces 8a and 8a are engaged with each other. As described above, the outer frame 4 to which the second outer frame mounting member 19 is attached via the first outer frame mounting member 18 is aligned with the opening 3 of the floor 1, and each of the second outer frames on the four sides. The screw 20 inserted through the screw insertion hole 19d is screwed into the joist 2 in a state where the attachment portion 19c of the attachment member 19 is close to the side surface of the joist 2 on the opening 3 side. At this time, the length of the outer frame 4 in which the second outer frame mounting member 19 coupled to the lower side of the engaging recess 8 on each side of the outer frame 4 via the first outer frame mounting member 18 is coupled. It moves in a direction orthogonal to the vertical direction, and the attachment portions 19c of the second outer frame attachment members 19 in the four directions can be easily brought close to the side surface of the joist 2 on the opening 3 side. As described above, the outer frame 4 is supported by the joist 2 via the second outer frame mounting member 19 and the first outer frame mounting member 18. At this time, each side of the outer frame 4 is connected to the joist 2 via the second outer frame mounting member 19 and the first outer frame mounting member 18 at two or three positions including the vicinity of both ends in the length direction of each side. It is what is supported.

  FIG. 11 shows a state in which the second outer frame attaching member 19 is attached to the joist 2 provided at a substantially regular position, and FIG. 12 shows the joist 2 provided at a position largely deviated outward from the regular position. The attachment state of the second outer frame attachment member 19 is shown. From these figures, the second outer frame mounting member 19 can be finely adjusted by sliding the second outer frame mounting member 18 with respect to the first outer frame mounting member 18 according to the mounting error of the joist 2, and the outer frame 4 is opened. It will be attached in the part 3.

  As described above, the lid body 10 is fitted into the outer frame 4 attached in the opening 3, the lid plate 11 of the lid body 10 is received by the lid body receiving portion 7 of the outer frame 4, and the back surface of the lid plate 11. Both ends of the lid reinforcing material 16 are received by the lid reinforcing material receiving portion 9. The outer frame 4 is supported by the second outer frame mounting member 19 being screwed to the joist 2 at each side, but the first outer frame mounting member 18 slides on the outer frame 4. Even when the second outer frame mounting member 19 is slidably engaged with the first outer frame mounting member 18, the sliding directions on the two adjacent sides intersect each other. Therefore, the movement of the outer frame 4 on the first outer frame mounting member 18 is restricted, and the outer frame 4 is supported on the first outer frame mounting member 18 in a fixed position.

  In the above embodiment, the first and second outer frame attachment members 18 and 19 are made of a synthetic resin material, but may be made of a metal material.

  The underfloor inspection port according to the present invention is an underfloor inspection port having excellent assembling workability by eliminating the receiving bar that has been attached to the joist by nailing.
