[0002]

[Prior art]

 Conventionally, when mounting an object to be supported on a side wall of a concrete structure, a female screw is embedded in the side wall, a male screw is screwed into this female screw, and a hole for the object to be opened that has been opened in advance is inserted into this male screw. The nut was screwed onto the male screw from the outside, and the supported object was attached to the side wall. In many cases, concrete structures are constructed by on-site casting work, which often causes the wall surface angle to not be constructed exactly as designed, and the side wall at a predetermined position must have a female screw at a predetermined angle. It is difficult to drive, and if a male screw is screwed onto this female screw, it will protrude in the direction that the male screw is out of alignment, and the male screw will pass through the hole of the However, the object to be supported is not attached in the correct posture position even if it is fixed, but it is attached to the side wall in an inclined state, and the object to be supported is attached to the side wall in an unstable state.

[0003]

[Problems to be solved by the device]

 The problem to be solved by the present invention is to solve these conventional problems, and to firmly and reliably support the object to be supported in a stable state even if the side surface or the female screw is not accurately installed on the side wall. The purpose is to provide a mounting bracket for construction.

[0004]

[Means for Solving the Problems]

 The structure of the present invention which solves the above problem is such that a screw shaft is screwed into the inside of a cylindrical body having a receiving portion having a spherical surface on one side and an engaging portion on the other side, and an opening is formed at the center. The outer peripheral surface of the opening is provided with a recessed plate that is in close contact with the spherical surface of the receiving part and is loosely fitted to the outside of the cylinder, and the holding plate with the opening in the center is inserted into the screw shaft to insert the cylinder. It is an architectural mounting fitting characterized in that it is detachably and loosely engaged with an engaging portion of a body, and a nut is screwed to a screw shaft on the outside thereof. The metal fittings for construction are preferably made of metal. The plan shape of the backing plate / holding plate may be a polygon such as a circle, a triangle, a quadrangle, a pentagon or a hexagon. The loose engagement of the pressing plate with the tubular body means that the pressing plate is engaged with the tubular body so as not to rotate around the screw shaft and can be swung to some extent with respect to the screw shaft.

[0005]

[Action]

 In the present invention, a screw shaft is attached to the side wall of a concrete structure in advance, a cylinder is screwed onto this screw shaft, and a receiving plate is loosely fitted into the cylinder to form a recess provided on the outer periphery of the opening of the receiving plate. Is brought into contact with the spherical surface of the receiving portion of the cylindrical body. A hole of the object to be supported opened in advance is fitted into the screw shaft and loosely fitted to the cylinder body, and the pressing plate is fitted into the screw shaft from the outside thereof and detachably loosely engages with the engaging portion of the cylinder body. Furthermore, a nut is screwed onto the screw shaft from the outside to firmly clamp the supported object between the receiving plate and the holding plate, and the supported object is stably attached to the side wall of the concrete structure.

At this time, since the recessed portion provided on the outer periphery of the opening of the receiving plate is slidably in close contact with the spherical surface of the receiving portion provided on the cylindrical body, the receiving plate is swingable and is always covered with a large ground contact area. The object to be supported can be held by coming into contact with the object to be supported. It is possible to fix the supported object at a fixed position or at a predetermined angle by combining multiple sets of building fixtures or combining other bolts.

If the female screw member is not attached to the supported object at a predetermined angle, the screw shaft screwed into the female screw member will protrude in the direction deviated, but it is provided on the outer periphery of the opening of the receiving plate. Since the recess is slidably intimately in contact with the spherical surface of the receiving part provided on the cylindrical body, the receiving plate loosely fitted on the cylindrical body is free to swing and always contacts the supported object with a large ground area regardless of the screw shaft. Also, since the hole opened in the supported object in which the tubular body is loosely fitted together with the screw shaft is a hole having a diameter larger than the diameter of the cylindrical body, the supported object directly intersects with the screw shaft protruding in the displaced direction. There is no end. Furthermore, since the holding plate loosely engaged with the cylinder swings with respect to the screw shaft, the holding plate can be brought into contact with the object to be supported in its entire surface in a state parallel to the receiving plate. Even if the screw axis is misaligned and protrudes, it is possible to mount the supported object in a stable state with the receiving plate and the pressing plate. Further, when the pressing plate is rotated, the cylinder engaged with the pressing plate is rotated around the screw shaft and can be moved back and forth. Therefore, when mounting a plurality of supported objects on the side wall, Can be easily uniformed.

The screw shaft is attached not to the side surface of the concrete structure but to the object to be supported, and the cylinder screwed to the screw shaft is inserted into the hole provided in the side wall of the concrete structure to receive the concrete side wall. The object to be supported may be attached to the concrete side wall by firmly sandwiching it with the holding plate.
