A lateral elongated side hole for receiving is formed, and a lower elongated hole corresponding to the side elongated hole is formed at a lower portion of the carry, and a tip of the support bolt is connected to the lower elongated hole. The adjusting screw passing through the elongated hole, characterized in that within the lower director hole and fixed by adjusting the inner and outer dimension of the opening.
[0008]
It is preferable that a decorative plate for covering the periphery of the opening of the anchor and receiving the nut is disposed between the fixing nut and the surface of the concrete frame.
[0009]
BEST MODE FOR CARRYING OUT THE INVENTION
FIG. 1 shows an example in which a door is provided in an opening 1a formed in a concrete wall of an apartment house or the like so as to be openable and closable. Reference numeral 1 denotes a concrete frame, 1a denotes an opening, and 4 denotes a door.
[0010]
As shown in FIG. 2, a hinge metal 2 is directly fixed to the concrete frame 1, and an elbow 5 fixed to a door 4 is rotatably fitted to a hinge shaft 3 of the hinge metal 2.
[0011]
As shown in FIGS. 3 and 4, the hinge hardware 2 includes a support bolt 6 protruding from the concrete frame 1 and a hinge shaft 3 for rotating the door 4 connected to the tip of the support bolt 6. And carry-on 7.
[0012]
An anchor 8 is embedded in the concrete skeleton 1, and the base of the support bolt 6 is screwed into the anchor 8. The tip of the support bolt 6 is formed slightly flat (see FIG. 4), and a screw hole 10 is formed through the flat portion 9 so as to be orthogonal to the plane.
[0013]
A decorative plate 11, a spring washer 12, and a fixing nut 13 are attached to the support bolt 6. The decorative plate 11 covers a peeled portion formed on the periphery of the opening 1a of the concrete skeleton 1 when the anchor 8 is embedded.
[0014]
Next, the carry-in 7 has a hinge shaft 3 formed on the upper surface of a block-shaped main body 7a. A laterally long side hole 15 for receiving the tip of the support bolt 6 is formed on one side of the main body 7a. ing. Since the tip of the support bolt 6 is formed as the flat portion 9, the width of the side long hole 15 can be smaller than the diameter of the support bolt 6. For this reason, the main body 7a can be formed compact.
[0015]
As shown in FIG. 4, a lower slot 16 corresponding to the side slot 15 is formed in the lower part of the carry-in 7. The side long hole 15 and the lower long hole 16 are formed to extend inward and outward of the opening 1a of the concrete skeleton 1, and communicate with each other at the back of the long hole. The width of the lower slot 16 is substantially the same as the diameter of the adjusting screw 17 so that when the adjusting screw 17 is inserted into the lower slot 16, it does not move in the width direction.
[0016]
The flat end portion 9 of the support bolt 6 is formed to have a height that can be fitted into the side long hole 15 and a size that can slide along the side long hole 15. Further, when the support bolt 6 is inserted from the side long hole 15, the screw hole 10 of the flat end portion 9 is formed so as to face the lower long hole 16.
[0017]
Next, the usage of the hinge hardware 2 having the above configuration will be described with reference to FIG. 2. First, the tip of the support bolt 6 is inserted into the side long hole 15 of the feed body 7 a, and the adjusting screw 17 is inserted through the lower long hole 16. The tip of the support bolt 6 is loosely screwed into the screw hole 10 of the flat end 9 of the support bolt 6. Then, the base of the support bolt 6 is screwed into the anchor 8, and by adjusting the screwing depth, the length of the protrusion of the support bolt 6 from the concrete frame 1 is determined. 1a is properly adjusted in the width direction and fastened with the fixing nut 13. At this time, the decorative plate 11 is in contact with the periphery of the concrete anchor opening 14, and the fixing nut 13 is fastened via the spring washer 12. As a result, the peeled portion formed on the peripheral edge of the anchor opening 14 when the anchor 8 is buried is covered, so that the appearance is favorably maintained. In addition, the fixing nut 13 and the spring washer 12 are not pressed against the rough and inferior surface of the concrete skeleton 1 but are pressed against the flat and high-strength metal decorative plate 11. 6 can be securely held. FIG. 5 shows a state where the screwing depth of the support bolt 6 is increased and the position of the hinge shaft 3 is adjusted to approach the concrete skeleton 1 side.
[0018]
Further, by moving the flat end portion 9 of the support bolt 6 along the long side hole 15 of the feed main body 7a, the size of the hinge shaft 3 in the inside and outside directions of the opening 1a is adjusted, and the position is determined. By the way, the adjusting screw 17 is strongly tightened via the spring washer 12, and the carrying body 7a is connected and fixed to the support bolt 6. FIGS. 6A and 6B are plan views showing the state when the adjustment is performed in the inward and outward directions.
[0019]
If the elbow 5 fixed to the side end of the door 4 is fitted and supported on the hinge shaft 3 after fixing the carry-in 7, the door 4 is supported rotatably with respect to the carry-in 7.
[0020]
As described above, by adjusting the screwing depth of the support bolt 6, the position of the carrying body 7a in the frontage direction of the hinge shaft 3 can be adjusted, and the carrying body 7a is inserted into the side elongated hole 15 with respect to the supporting shaft. The position of the hinge shaft 3 in the inward and outward directions can be adjusted by moving the hinge shaft 3 along.
[0021]
Since the position adjustment and the fixing work are performed by tightening the fixing nut 13 and the adjusting screw 17, a wrench may be used. Therefore, the work can be easily performed.
[0022]
