It is sectional drawing of the said AA equivalent position explaining the construction method of a floor. It is a downturn figure after laying a floor panel.

Hereinafter, an embodiment of the present invention will be described with reference to the drawings.
As shown in FIGS. 1 to 4, the steel pulling 1 of the present embodiment includes a lower member 2 fixed to the base F, and a floor member on the upper surface fixed to the lower member 2. The upper member 3 that can support the floor panel P and the height adjuster 6 that can be temporarily held by adjusting the height position of the upper member 3 relative to the lower member 2 are configured.

  In the present embodiment, the lower member 2 is made of a long groove-shaped steel with the groove portion facing upward, and the bottom plate portion 2a attached to the foundation F and the widthwise direction of the bottom plate portion 2a upward from both ends. It is composed of a pair of flange-like rising pieces 2b and 2b extending vertically. Bolt holes 2h are provided in the bottom plate portion 2a at positions corresponding to anchor bolts B protruding from the upper surface of the foundation F, for example.

  In the present embodiment, the upper member 3 is made of channel steel with the groove portion facing downward, and includes an upper plate portion 3a that forms an upper surface on which the floor panel P is placed, and downward from both ends of the upper plate portion 3a. It has a pair of drooping pieces 3b and 3b extending vertically.

The upper member 3 is provided with a height adjuster 6. In the present embodiment, the height adjuster 6 of the present embodiment penetrates the upper plate portion 3a of the upper member 3 and has a hole 6a having a thread groove, and is screwed into the hole 6a from above and has a lower end that is the lower member 2 described above. The screw shaft 6b is in contact with the bottom plate 2a without being screwed. The screw shaft 6b has a screw length sufficiently longer than the height dimension h of the upper member 3, for example. Thereby, the protrusion length protruding below the lower edge 3be of the upper member 3 can be freely adjusted by screwing the screw shaft 6b back and forth with respect to the hole 6a. In addition, in this embodiment, although the height adjustment tool 6 is formed in at least 4 corners in planar view of the upper member 3, the number can be increased / decreased arbitrarily. Further, the hole 6a has a thread groove corresponding to the screw shaft 6b formed in advance on the inner peripheral surface thereof, but the hole 6a may not be formed with such a thread groove. In this case, when the screw shaft 6b is screwed into the hole 6a, the screw shaft 6b is not loosely fitted in the hole 6a but is positioned by being bitten into the hole 6a. The inner diameter of the hole 6a is preferably substantially the same as or slightly smaller than the screw diameter of the screw shaft 6b so as to change only by rotation.

  In the present embodiment, the groove width W1 of the upper member 3 is formed slightly larger than the width W2 between the rising pieces 2b, 2b of the lower member 2. Thereby, as shown in FIG. 2, each hanging piece 3 b of the upper member 3 can be fitted to the rising piece 2 b of the lower member 2 from the outside and can be extrapolated. Can be slidably fitted in the direction. That is, the drooping piece 3b and the rising piece 2b are overlapped with each other with an adjustable overlap L in the height direction.

  Then, in a state where the lower member 2 and the upper member 3 are fitted together, the screw shaft 6b is screwed back and forth to change the protruding length from the lower edge 3be of the hanging piece 3b of the upper member 3, thereby making it possible to virtually show FIG. As indicated by the line, the height of the upper surface of the upper member 3 can be adjusted steplessly within the range of the distance H with respect to the lower member 2. Moreover, since the upper member 3 is temporarily held by the screw shaft 6b protruding downward from the lower edge 3be of the hanging piece 3b, the adjusted state can be maintained without using a separate holder or the like.

  Further, in the present embodiment, the penetrating pieces 3b of the upper member 3 are formed with through holes 3h at a predetermined pitch in the length direction. The through hole 3h is desirably formed close to the lower edge 3be side of the drooping piece 3b, for example. On the other hand, such a through hole is not formed in the rising piece 2 b of the lower member 2.

  The lower member 2 and the temporarily held upper member 3 are fixed by screwing screws 4 as fixing tools from the side (main fixing). In the present embodiment, the screw 4 is screwed into the overlapping portion 5 where the hanging piece 3b and the rising piece 2b overlap. The screw 4 is a drill screw, for example, and is inserted from the through hole 3h of the drooping piece 3b and penetrates the rising piece 2b of the lower member 2 by being screwed. Thereby, the lower member 2 and the upper member 3 are integrally fixed in a state in which they cannot move in the height direction.

  As is clear from the above, the lower member 2 and the upper member 3 are slid in the height direction with respect to the lower member 2 in a state before being fixed by the screws 4, so that the overlapping is performed. By adjusting the margin L, the height of the upper surface can be adjusted steplessly and easily on site. Therefore, in the very limited narrow space between the floor panel P and the foundation F on the first floor, the leveling function can be exhibited by the draw 1 itself with a simple configuration. Therefore, even if the foundation F is uneven, this can be absorbed by the level matching function of the large draw 1, and the workability can be greatly improved and the finishing accuracy of the floor can be improved. The screw shaft 6b can be removed after the lower member 2 and the upper member 3 are fixed to each other.

  Next, an embodiment of a floor construction method using such a steel pulling 1 will be described. First, FIG. 5 shows a plan view of the floor foundation of the first floor of an industrialized house in which the steel puller 1 of this embodiment is used, and FIG.

  The floor foundation includes a foundation F and a plurality of bundle members 7 erected in a grid shape at a predetermined module pitch on, for example, soil concrete D surrounded by the foundation F.

  The foundation F includes, for example, an outer foundation Fa disposed on the outer wall of a house and an inner foundation Fb having one end connected to the outer foundation Fa and extending through the interior of the house.

  Further, as shown in FIG. 6, the bundle material 7 is fixed on the soil concrete D and extends upward, and a screw screwed to the leg portion 7a so that the height can be adjusted up and down. A shaft portion 7b and a metal fitting 7c having a U-shaped cross section that is fixed to the upper end of the screw shaft portion 7b and can hold the first large pull 9 having a substantially pipe-shaped cross section in the present embodiment. .

  In the construction method of the present embodiment, first, a step of fixing the lower member 2 to the anchor bolt B protruding from the upper surface of the inner foundation Fb is performed. That is, as shown in FIGS. 3 and 6, the anchor bolt B is inserted into the bolt hole 2h of the bottom plate portion 2a, and the nut N is screwed onto the bolt shaft protruding from the bottom plate portion 2a. Thereby, the lower member 2 is attached on the inner foundation Fb. In addition, the lower member 2 can be fixed to the foundation F by using, for example, an adhesive other than the anchor bolt B. Further, a base or a floating member (not shown) may be interposed between the inner base Fb and the lower member 2 in order to form, for example, a ventilation channel. In addition, a wooden base 8 is fixed on the outer foundation Fa in consideration of, for example, the connectivity with an outer wall panel (not shown).

  Moreover, the process of fixing the 1st large drawing 9 extended in parallel with the said lower side member 2 to positions other than the foundation F to the metal fitting 7c of the said bundle material 7 using a volt | bolt etc. is performed. As described above, the bundle material 7 of the present embodiment is one that can adjust the height of the metal fitting 7c relative to the soil concrete D. Therefore, the first draw 9 supported by the bundle 7 is different from the draw 1 of the above embodiment, and a standard draw that does not have a level matching function is used. The pulling 9 may be a wood material. However, it goes without saying that instead of the first pull 9, the pull 1 may be used.

  Next, as shown in FIG. 3, the upper member 3 is fitted to the lower member 2 fixed to the foundation F, and the upper member 3 is slid in the height direction with respect to the lower member 2, so The overlap margin L between 3b and the rising piece 2b is adjusted. As a result, level adjustment is performed to adjust the upper surface of the upper member 3 to the same height as the upper surface of the first pulling 9 (adjustment process).

In this step, as shown in FIG. 6, for example, a reference level is generated using a water thread HL or the like, and the height position of the upper member 3 is adjusted accordingly. As described above, this adjustment is performed by turning the screw shaft 6b of the height adjuster 6 clockwise or counterclockwise with respect to the upper plate portion 3a, thereby reducing the protruding length from the lower edge 3be of the hanging piece 3b. It can be done by adjusting. In addition, during this adjustment, the upper member 3 is held in its state by the screw shaft 6b, so that the adjustment work can be performed efficiently and the workability is greatly improved. In addition, about the bundle material 7, the upper surface height of the 1st large drawing 9 can be adjusted using the screw shaft part 7b.

When the adjustment process is completed, the lower member 2 and the upper member 3 are permanently fixed together by screwing screws into the overlapping portion 5 of the hanging piece 3b and the rising piece 2b from the side (fixing process). . As a result, as shown in FIG. 7, it is possible to form the second fork 10 extending at the same height as the first fork 9. In addition, since the screw shaft 6b of the height adjuster 6 is not particularly required after the lower member 2 and the upper member 3 are permanently fixed, it is desirable to remove them in advance before the next floor material construction process. (Screw shaft removing process). Thereby, interference with the screw shaft 6b and a flooring can be prevented.

  Thereafter, as shown in FIG. 8 and FIG. 9, the floor panel P that is a flooring material is fixed across the first pull 9 and the second pull 10. The floor panel P of the present embodiment has a substantially square shape including a joist 12, a face material 13 fixed thereon, and a heat insulating material 14 disposed therebetween. For example, the floor panel P includes: Both ends are fixed to the large pulls 9 and 10 using a drill screw 15 penetrating the joist 12. A floor finish or the like is laid on the outside of the face material 13.

As described above, according to the floor construction method of the present embodiment, the overlap margin L between the hanging piece 3b of the upper member 3 of the steel pulling 1 and the rising piece 2b of the lower member 2 is set as a height adjuster. 6 can be performed while adjusting and temporarily holding. Therefore, the upper surface of the upper member 3 can be easily adjusted to the same height as the other adjacent large upper surfaces, so that the workability can be greatly improved and the floor finishing accuracy can be increased.

  Although the embodiments of the present invention have been described above, the present invention is not limited to the specific embodiments described above, and can be modified into various embodiments. For example, in the above embodiment, the lower member 2 and the upper member 3 are both made of channel steel, but one of them may be shaped like a square pipe. Further, in the above embodiment, the upper member 3 is extrapolated to the lower member 2, but the upper member 3 may be fitted into the groove of the lower member 2 on the contrary.
