DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for suspending an external wall material used for lifting an external wall material made of a PCa plate or the like with a lifting machine such as a crane (hereinafter referred to as a "crane") and mounting it on a building under construction. About jigs.

2. Description of the Related Art In the construction work of high-rise buildings and the like, PCa
When an external wall material made of a board or the like is lifted by a crane and attached to a building under construction, the external wall material is lifted by a crane via a hanging jig. The hanging jig includes a horizontal member to which a hanging wire of a crane, a horizontal balancer, or the like can be attached at one end, and a vertical member that hangs from the other end of the horizontal member and can attach an outer wall material.

A method of attaching an outer wall member to a building under construction using a hanging jig will be described. First, one end of the outer wall member placed on a truck bed is attached to a vertical member of the hanging jig. . At this time, the suspension jig is mounted such that the horizontal member is positioned above the upper end of the outer wall material and the vertical member is positioned on the back surface of the outer wall material. Then, the outer wall material is lifted by a crane and attached to a predetermined position of the building under construction. When the attachment of the outer wall material is completed, the connection between the outer wall material and the vertical member of the hanging jig is released. Next, work to pull the hanging jig out of the building, that is, in the horizontal direction,
In this state, the outer wall material collides with the vertical member of the hanging jig on the back side, and cannot be pulled out of the building. Therefore, the hanging jig is temporarily lifted by the crane so that the lower end of the vertical member of the hanging jig is positioned above the upper end of the outer wall material, and then the hanging jig is drawn out of the building.

[0004] By repeating these series of operations, the outer wall material is attached to the building under construction.

[0005]

However, according to the above-described mounting method, just above the outer wall material mounted on the building,
If the lower end of the self-elevating outer curing frame is located, there is no space to lift the lifting jig using a crane, so the lifting jig may be pulled out of the building. could not. And the reason why this hanging jig cannot be pulled out of the building is
The vertical member of the hanging jig remains fixed to the horizontal member.

Here, the self-elevating type outer peripheral curing frame will be described.
There is a thing described in 331431 gazette, specifically,
In order to prevent the materials from being scattered from the building under construction or to prevent the worker from falling down, etc., the outer peripheral surface curing member is arranged on the outer peripheral surface of the building to perform curing, and the curing member is attached to the outer wall. By raising or lowering during construction, the outer peripheral surface of the upper or lower floor is cured. According to the self-elevating outer peripheral curing frame, there is no need to lift the curing member with a crane and attach it to the building under construction.
The labor can be reduced, and the outer peripheral surface of the building under construction can be quickly cured.

When the self-elevating outer peripheral curing frame is used, as described above, in order to allow the hanging jig to be pulled out of the building under construction, the upper end of the outer wall material is required. It is necessary to increase the distance between the lower end of the self-elevating type outer peripheral curing frame. However, if this interval is widened, the outer peripheral surface of the building in the meantime will not be cured, and a problem will occur in terms of safety. Therefore, in order to ensure that the lifting jig can be lifted by the crane while ensuring safety, an outer wall material is further attached between the upper end of the outer wall material and the lower end of the self-elevating type outer peripheral curing frame. Therefore, it was not possible to make the most of the reduction in labor, which is an advantage of the self-elevating type outer peripheral curing frame.

Therefore, an object of the present invention is to eliminate the step of lifting the hanging jig by a crane after disconnecting the connection between the outer wall material and the vertical member of the hanging jig, thereby enabling quick work. By allowing the hanging jig to be drawn out of the building under construction without increasing the distance between the upper end of the outer wall material and the lower end of the self-elevating outer peripheral curing frame, etc. Another object of the present invention is to eliminate the need for further curing between the upper end of the outer wall material and the lower end of the self-elevating outer peripheral curing frame.

[0009]

In order to achieve the above object, a hanging jig for an outer wall material according to the present invention comprises a horizontal member for attaching a lifting machine such as a crane at one end, and a hanging member hanging from the other end of the horizontal member. And a vertical member to which an outer wall material can be attached. The other end of the horizontal member and the upper end of the vertical member are connected so that the vertical member can swing freely by a support shaft, and the horizontal member and the vertical member include the vertical member with respect to the horizontal member. There is provided a horizontal maintaining mechanism for maintaining the horizontal.

[0010] Here, a horizontal balancer may be interposed between the crane and the horizontal member. In addition, the horizontal member and the vertical member do not always mean that these members are in a horizontal or vertical state. It is an expression.

According to the present invention, there is no need for a step of lifting the hanging jig by a crane before the hanging jig is moved outside the building after the connection between the outer wall material and the vertical member of the hanging jig is released. Therefore, work can be performed quickly. In addition, the hanging jig can be pulled out of the building under construction without increasing the distance between the upper end of the outer wall material and the lower end of the self-elevating outer peripheral curing frame. It is not necessary to provide any further curing between the lower end of the outer peripheral curing frame and the like.

In the vicinity of the right end of the horizontal member 1, the upper end of the vertical member 7 is pivotally mounted by a support bolt 4 serving as a support shaft, and a nut 41 is screwed to this bolt. A fixing bolt 5 penetrates the horizontal member 1 and the vertical member 7, and a nut 51 is screwed into the horizontal member 1 and the vertical member 7, whereby the vertical member is fixed to the horizontal member and maintains a vertical state. A bracket 23 protrudes upward from the horizontal member 1, and a hole 24 is formed in the bracket 23.
Is turned around to reach the horizontal position, the hole of the vertical member through which the bolt 5 has penetrated overlaps the hole 24. Then, by inserting a rod-like member such as a bolt into these holes, the horizontal state of the vertical member 7 is maintained. Thus, by these holes and the rod-shaped member,
A horizontal maintenance mechanism is configured.

Further, a small hole 71 is opened in the vertical member 7, and when the vertical member turns upward, this overlaps with the hole 24, and by inserting a rod-shaped member into these holes, the vertical member turns upward. The state is maintained. The vertical member 7 is for attaching the outer wall material 6, and a mounting plate 8 to which the outer wall material can be attached is attached to the vertical member. The mounting plate 8 includes a fixing portion 82 fixed to the vertical member 7 with bolts and nuts 81, and a supporting portion 83 integrally formed with the fixing portion 82 and supporting the outer wall material 6. The fixing portion 82 has a plate shape perpendicular to the surface of the outer wall material 6, and the support portion 83 has a plate shape parallel to the surface of the outer wall material.

A long hole 84 is formed in the support portion 83 in the vertical direction, and a nut 62 is screwed into the hole 84 through a hook shaft 61 provided on the back surface of the outer wall material 6. Has become. A plurality of hook shafts 61 are protruded in the horizontal direction, and a plurality of long holes 84 are also opened in the support portion 83 in the horizontal direction. 9 is a metal fitting provided on the upper surface of the slab of the building, and 91 is a bolt screwed to a cap nut 92 welded to the metal fitting.

Attachment of the outer wall material to the hanging jig First, both members are fixed with the support bolt 4 and the fixing bolt 5 so that the vertical member 7 hangs down from one end of the horizontal member 1. Then, the vertical member 7 is attached to one end of the outer wall material 6 placed on the truck bed. In particular,
The distal end of the retaining shaft 61 attached to the upper end of the outer wall material 6 is inserted into the elongated hole 84 formed in the mounting plate 8, and the nut 62 is screwed into the distal end. Then, the outer wall material is supported by pressing the outer wall material with the pressing portion 32 of the support member 31 attached to the horizontal member 1.

Before or after this, a wire rope or the like of a crane is attached to a retaining hole 2a of a retaining plate 2 attached to the right end of the horizontal member 1 via a connecting member (not shown) or the like. When the hanging jig is attached to the outer wall material 6 placed on the truck bed, the horizontal member 1 is in a vertical state, and the vertical member 7 is in a horizontal state. 2. Next, the work of erecting the outer wall material 6 with a crane is performed. Specifically, when the outer wall material 6 is started to be lifted by the crane, the outer wall material is gradually lifted from one end to which the vertical member 7 is attached. Then, when the outer wall material 6 is completely lifted from the truck bed, the outer wall material is in a vertical state, and in this state, the outer wall material is further lifted to a predetermined place in the building under construction.

When the outer wall material 6 is lifted by a crane, that is, when the outer wall material is in a vertical state, the horizontal member 1 is in a horizontal state.
The vertical member 7 is in a vertical state. 3. Attachment of outer wall material to building Next, an operation of attaching the outer wall material 6 to a predetermined location of the building is performed. Specifically, when the outer wall material 6 is lifted to a predetermined height, the outer wall material is brought to the building. Then, in addition to placing the protrusion of the outer wall material 6 on the bolt 91, the outer wall material 6 is attached to the building frame using a fastener (not shown). 4. Removal of the hanging jig from the outer wall material After the outer wall material 6 is attached to the building, a work of releasing the connection between the outer wall material and the vertical member 7 is performed. Specifically, the vertical member 7
The nut 51 is removed from the fixing bolt 5 inserted into the through hole formed at the upper right end of the, and the fixing bolt is pulled out from the through hole. At the same time, the nut 62 attached to the tip of the hook shaft 61 is removed, the lower end of the vertical member 7 is lifted, and the vertical member is swung in the direction of the arrow in the drawing until the vertical member becomes horizontal.

After the nut 62 attached to the tip of the hook shaft 61 is removed, the nut 5 is removed from the fixing bolt 5.
