After that, the fixing nut 10 is inserted through the opening 4 on the upper surface side of the pulling pulley 2 and screwed into the screw portion 7 of the bundle 1, and the wrench 11 or the like is further inserted through the opening 4 on the upper surface side. By inserting a tool and tightening the fixing nut 10 to directly press the bottom surface 2b of the large pulley 2 from above with the fixing nut 10, the large pulley 2 can be fixed. DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described below based on embodiments shown in the accompanying drawings. The puller 2 of the present embodiment is made of steel and has a substantially cylindrical cross section as shown in FIGS. 1 and 4, and has a top surface 2a and a bottom surface 2b which extend vertically. Opening portions 4 and 5 are provided respectively. The opening 4 on the top side is used as a working opening through which a tool such as a wrench 11 can be inserted, and the opening 5 on the bottom side is used for inserting the threaded portion 7 of the bundle 1 into the inside of the large pulley 2. Is done. The openings 4 and 5 are provided at a plurality of locations at intervals in the longitudinal direction of the pulley 2 (perpendicular to the plane of FIG. 1). It has become supported. FIG. 4 shows a large support bracket 3 for supporting the large pulley 2.
As shown in the figure, the plate 6 is formed in a circular shape, and a hole 6 is opened at the center of the plate-shaped large support metal fitting 3. It communicates with the part 5. As shown in FIG. 1, the bundle 1 is integrally formed of a pipe-shaped lower bundle 1a and an upper bundle 1b composed of a screw portion 7. The lower end of the lower bundle 1a is fixed to a base surface 8 such as a base foundation or a slab using a fixing tool (not shown). The base surface 8 on which the lower bundle 1a is erected is not particularly limited, and may be, for example, a floor slab. The screw portion 7 constituting the upper bundle portion 1b is fixed to the upper end portion of the lower bundle portion 1a by a fastening nut 40, and the lower portion of the screw portion 7 is inserted inside the lower bundle portion 1a. The upper portion 7 is inserted into the inside of the large pulley 2 through the hole 6 provided in the large pulley 3 and the opening 5 on the bottom side of the large pulley 2. A level adjusting nut 9 is fixed to the central upper surface of the large-size support fitting 3 by welding or the like concentrically with the hole 6 through which the threaded portion 7 of the bundle 1 passes. The level adjusting nut 9 is screwed into the thread portion 7 of the bundle 1 inside the large pulley 2, and can be rotated by a wrench 11 inserted from the opening 4 on the upper surface side of the large pulley 2. . When the level adjusting nut 9 moves up and down along the threaded portion 7 of the bundle 1, the large support bracket 3 moves up and down integrally with the level adjusting nut 9, and the level adjustment of the large pull 2 is performed. It is. The outer diameter of the level adjustment nut 9 is set smaller than the opening 5 on the bottom side of the large pulley 2. The bottom portion 2b of the large pulley 2 can be stably supported in a state in which the bottom portion 2b is in close contact with the large pulley support 3. A fixing nut 10 for fixing the large pulling 2 to the large pulling support 3 is screwed into the thread portion 7 of the bundle 1 inserted into the large pulling 2. In this example, as shown in FIG. 4, the fixing nut 10 is formed of a cap nut, and the female screwing into the skirt portion 10 b having a diameter larger than the outer diameter of the level adjusting nut 9 and the screw portion 7 of the bundle 1. And a screw portion 10a. The fixing nut 10 made of this cap nut is
After adjusting the level of the pulling pulley 2, it is inserted through the opening 4 on the upper surface side of the pulling pulley 2 and screwed into the screw portion 7 of the bundle 1,
After that, the skirt portion 1 is tightened by a wrench 11 inserted through the opening 4 on the upper surface side.
The lower end edge 10c of Ob is directly pressed from above onto the bottom portion 2b of the large pulley 2 so that the large pullout 2 can be fixed to the large pulling support 3 so as not to move. In order to adjust the level of the pulley 2, a wrench 11 (FIG. 4A) is inserted from above the pulley 2 into the opening 4 on the upper surface side to adjust the level shown in FIG. The operating nut 9 is rotated. At this time, the large support fitting 3 integrally fixed with the level adjusting nut 9 rotates together. However, at this stage, the large pulley 2 is not fixed to the large support fitting 3, 2, the large support metal 3 rotates free and the large support metal 3 can be moved up and down along the screw portion 7 of the bundle 1 together with the level adjusting nut 9 as shown in FIG. Fine adjustment of the level of the pulling pulley 2 and leveling work can be easily and accurately performed from the pull pulley 2 in an easy posture. After the level adjustment is performed in this manner, the fixing nut 10 is inserted through the opening 4 on the upper surface side of the large pulley 2, and the female screw portion 10 a of the fixing nut 10 is temporarily screwed into the screw portion 7 of the bundle 1. Then, a wrench 11 (FIG. 4A) is inserted through the opening 4 on the upper surface side of the pulling pulley 2, and the fixing nut 10 is tightened. As a result, as shown in FIGS. 3 and 4B, the level adjusting nut 9 is accommodated inside the skirt portion 10b of the fixing nut 10, and the lower end edge 10c of the skirt portion 10b is attached to the bottom of the large pulley 2. The large pulley 2 is directly pressed against the portion 2b and is fixed so as not to float on the large pulley support fitting 3, so that the work of fixing the large pulley 2 in an easy posture from the large pulley 2 can be easily and reliably performed. Will be able to do it. As a result, as in the prior art,
It is not necessary to perform the level adjustment work of the large pulley 2 in the narrow space below and to perform nailing from the side of the large pulley 2 without having to take time and effort to adjust and fix the level of the large pulley 2. , Can be constructed at the height position as designed. In this embodiment, since a cap nut is used as the fixing nut 10 for fixing the pulling pulley 2, the skirt portion 10b of the fixing nut 10 is released to the outside of the level adjusting nut 9 to lower the lower end edge thereof. 10c is the bottom 2b
Can be pressed directly from above, so that the pulling nut 2 can be easily fixed by the fixing nut 10.
Further, since the lower end edge 10c of the skirt portion 10b of the cap nut is arranged concentrically with the screw portion 7 of the bundle 1, the pressing of the large pulling 2 by the skirt portion 10b is performed without bias, and the large pulling is achieved. 2 can be stabilized. The rigidity of the large pulley 2 can be increased by forming the steel pulley 2 with a rectangular cross section, and the opening 4 is formed in the upper surface 2a and the bottom surface 2b of the pulley 2. , 5
It is only necessary to form the openings 4 and 5 easily. Moreover, by opening the opening 5 on the bottom side even after construction,
This opened opening 5 can also be used as a drainage hole, and there is also an advantage that, for example, when water is flooded above the floor or below the floor, water is drained from the inside of the pulley 2 smoothly. Further, since the large-size support 3 is formed in a flat plate shape, the large-size support 3 can be smoothly rotated while the large-size support 2 is placed on the large-size support 3.
The shape of the large-sized support fitting 3 can be simplified, and the material cost can be reduced. Of course, the shape of the heavy metal support 3 is not limited to a flat plate. For example, if the level adjusting nut 9 is not integrally fixed to the heavy-duty support fitting 3 but is rotatably fixed, it is possible to form a substantially U-shaped cross section as in the conventional example (FIG. 5). . As an example, a ring-shaped locking piece is provided on the side of the large support bracket 3 and a level adjusting nut 9 is provided.
A locking piece rotatably hooked on the locking piece is provided on the side, and the locking piece is rotatably hooked on the locked piece, so that the level adjustment nut 9 is rotatable with respect to the large support bracket 3. A method of fixing the position is considered. In this case, the large support bracket 3
Does not rotate together with the level adjustment nut 9 even when it is rotated, and only moves up and down together with the level adjustment nut 9. Accordingly, there is no restriction on the shape of the large-size support 3, and the range of selection of the large-size support 3 can be expanded. As described above, according to the present invention, the large top and bottom portions each having a substantially cylindrical cross section are provided with openings that are open vertically, respectively. The large support metal fitting has a hole communicating with the opening on the bottom side of the large metal support, and the upper part of the bundle passes through the hole of the large support metal and the opening on the bottom side of the large metal fitting, respectively. The screw portion of the bundle inserted into the inside of the large pulley is fixed to the screw portion of the bundle inserted into the large pulley from the opening on the upper surface side of the large pulley. A level adjustment nut that is rotated to move the large support bracket up and down, and a fixing nut that is tightened from the opening on the top side of the large pull and presses down on the bottom of the large pull to fix it Since the nut is screwed, a tool such as a wrench is inserted through the opening on the top By rotating the nut for level adjustment and moving the large support bracket up and down along the thread of the bundle,
Fine adjustment of the level of the pulling and leveling work can be performed easily and accurately with a comfortable posture from the pulling. Also, after level adjustment, insert the fixing nut from the opening on the upper side of the large pulley and screw it into the threaded part of the bundle, and insert a tool such as a wrench from the opening on the upper side to remove the fixing nut. By directly tightening the bottom surface of the large pulley from above with the fixing nut by the tightening operation, it is possible to easily and reliably fix the large pulley in an easy posture from above. As a result, there is no need to perform a large-scale level adjustment work in a narrow space below the large-scale pulling or to perform nailing from the lateral direction of the large-scale pulling as in the related art. Without having to spend much time, it can be installed at the height as designed.
