Installation method for hanging fixtures and exterior wall panels

Abstract

To provide a hanging tool with operability capable of easily and detachably engaging even in any case that an engagement hole formed in a hanging target member is a long hole or a round hole.SOLUTION: A hanging tool 4 comprises: a hollow cylindrical inserting shaft part 41 capable of inserting from above into an engagement hole (a long hole 22) formed by penetrating through a hanging target member (an external fastener 2); an operation mechanism assembling part 42 connected to an upper end side of the inserting shaft part 41 and suspended / held by a hanging rope; a retractable mechanism of an engaging claw 54 to laterally expose / retract the engaging claw 54; and a rotation stopper 61 installed to and along the inserting shaft part 41 in a direction intersecting a protruding direction of the engaging claw 54 and held so as to be able to slide along an axial direction of the inserting shaft part 41. A lower end part of the rotation stopper 61 abuts on an upper edge of a round hole when the engagement hole is the round hole. The rotation stopper 61 is inserted into the engagement hole when the engagement hole is the long hole, and the inserting shaft part 41 is constrained in a non-rotatable manner.SELECTED DRAWING: Figure 6

Claims

1. A hollow cylindrical insertion shaft portion that can be inserted from above into an engagement hole formed by penetrating the lifting target member in the vertical direction, An operating mechanism assembly part is coupled to the upper end of the insertion shaft portion and suspended by a suspension cable, An engagement claw extension / retraction mechanism that extends and retracts an engagement claw that can engage with the lower edge of the engagement hole toward the side of the insertion shaft portion, A rotation stopper is attached to the insertion shaft portion in a direction intersecting the protruding direction of the engagement claw, and is held so as to be able to slide along the axial direction of the insertion shaft portion, A suspension device equipped with the following.

2. In the suspension device described in claim 1, The rotation stopper is biased to be pushed out toward the lower end of the insertion shaft portion by a rotation stopper extrusion mechanism provided in the operating mechanism assembly portion. If the engagement hole is a round hole, the lower end of the rotation stopper abuts against the upper edge of the round hole. If the engagement hole is an elongated hole, the lower end of the rotation stopper is inserted into the engagement hole, thereby restricting the insertion shaft portion from rotating within the engagement hole. A lifting device characterized by the following features.

3. In the suspension device described in claim 2, The aforementioned rotation-stopping extrusion mechanism is A rotation-stopping sliding guide portion provided in the assembly portion of the operating mechanism, A slider is coupled to the upper end of the rotation stopper and engages with the rotation stopper sliding guide portion, and slides parallel to the axial direction of the insertion shaft portion, A rotation-preventing biasing member that pushes the slider toward the lower end of the insertion shaft portion, A suspension device characterized by being composed of including the following.

4. In the suspension device described in claim 1, 2, or 3, The aforementioned engagement claw extension / retraction mechanism is A crank arm is pivotally attached to the vicinity of the lower end of the insertion shaft portion via a first pin node so as to be swingable, A link arm connected to the upper end of the crank arm via a second pin node, A slide node holds the upper end of the link arm so that it can slide in the axial direction of the insertion shaft portion along an engagement claw retraction guide hole provided in the operating mechanism assembly portion, An engaging claw biasing member that pushes the slide node downward toward the lower end of the insertion shaft portion, It is equipped with, The engagement claw is provided at the lower part of the crank arm, The second pin node connecting the crank arm and the link arm is exposed on the side of the operating mechanism assembly and is assembled so as to be pushable toward the operating mechanism assembly. A lifting device characterized by the following features.

5. In the suspension device described in claim 4, The central axis of the slide node extends outward from the operating mechanism assembly, and an operating pull cord is tied to its extended end. The aforementioned pull cord is inserted through a guide ring provided on the upper part of the operating mechanism assembly and suspended downwards. A lifting device characterized by the following features.

6. In the suspension device described in claim 4, A lifting device characterized in that an arm cover covering the crank arm and the link arm is attached to the side of the assembly portion of the operating mechanism.

7. In the suspension device described in claim 1, 2, or 3, A lifting device characterized in that a backing plate, which can contact or lock onto a suitable location on the lifting target member when the insertion shaft portion is inserted into the engagement hole, is attached to the operating mechanism assembly portion via a backing plate support arm of a predetermined length.

8. The exterior wall fasteners, which extend to the back side of the exterior wall panel, are attached to the upper frame material of the frame attached to the back side of the exterior wall material. The exterior wall panel is lifted and the exterior wall fastener is mounted on the upper flange of the beam. In a method for attaching an exterior wall panel, in which an engagement hole formed in the exterior wall fastener and an attachment hole formed in the beam are overlapped and fastened with bolts and nuts, Insert the insertion shaft portion of the hanger described in claim 2 or 3 into the engagement hole of the outer wall fastener and engage the engagement claw with the engagement hole. The lifting device is used to hoist the exterior wall panel and transport it to the immediate vicinity of the beam. The lower end of the insertion shaft portion protruding downward from the exterior wall fastener is inserted into the mounting hole of the upper flange, and the engagement hole and the mounting hole are aligned, thereby mounting the exterior wall fastener on the upper flange of the beam. After further lowering the insertion shaft portion and temporarily engaging the engaging claw with the mounting hole of the upper flange, The engaging claw is retracted into the insertion shaft portion and the suspension device is pulled out above the beam and the outer wall fastener. Insert the bolts into the engagement holes and mounting holes and fasten the nuts. A method for installing exterior wall panels, characterized by the following features.
