In a pair of receiving members for suspending a panel by fastening a plurality of lifting members to the stopping unit, the shape of the load receiving bottom surface is a curved surface convex upward. The material of the bottom surface of the cargo is assumed to have elasticity such that the curved surface is deformed into a horizontal plane when the panel is placed and lifted.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a panel hoisting receiving member used when hoisting and moving a panel such as lightweight cellular concrete (hereinafter referred to as ALC).

[0002]

[Prior Art]

 Conventionally, when a panel such as an ALC is lifted and moved, a receiving member is applied to both lower edges of the panel such as the ALC in the long side direction, and lower ends of a plurality of wires are locked to both ends of the receiving member. , The upper end of the wire is put together on a sling member and suspended by a lifting means such as a crane.

[0003]

[Problems to be solved by the device]

 However, when a panel such as an ALC is lifted and moved by such a so-called triangular sling, the hanging wires are locked at both ends of the receiving member and lifted. Bends downward between the fulcrums of both ends that lock, that is, in the direction opposite to the panel lower surface. At this time, the weight of the panel is not supported by the entire bottom surface of the receiving member, but only by the bottom part of the receiving surface near the lifting fulcrum. Therefore, there was a problem that when the strength of the corner of the panel could not withstand the stress received from the bottom of the cargo receiving bottom, the corner of the panel was chipped. SUMMARY OF THE INVENTION An object of the present invention is to solve the above problems and to provide a panel hoisting receiving member that does not cause chipping at the panel corners.

[0004]

[Means for Solving the Problems]

 In order to achieve the above-mentioned object, in the panel hoisting receiving member of the present invention, a bottom surface of the cargo receiving side which is applied to the end of the short side of the lower surface of the panel, and a vertical surface which is applied to the lower end of the fore edge of the panel, In a pair of receiving members, which consist of two bottom stoppers fixed to the inside of the load receiving bottom surface and the vertical end from the end of the vertical surface at a substantially right angle, and a plurality of lifting members are fixed to the stoppers to lift the panel. A means is adopted in which the shape of the bottom surface of the cargo receiving surface is a curved surface convex upward, and the material of the bottom surface of the cargo receiving material is elastic enough to deform the curved surface into a horizontal plane when a panel is placed and lifted. I used it.

[0005]

[Action]

 The operation of the present invention is as follows. Place the short-side end of the bottom surface of the panel on the bottom surface of the cargo, and suspend the suspension wire on the receiving member and lift it up. Upon receiving it, the convex portion tries to deform downward. However, since the bottom surface of the load receiving part is made of an elastic body, when it is deformed to some extent, a repulsive force is generated upward against the deformation, the repulsive force and the load of the panel are balanced, and the deformation is eventually caused. Stop. In the present invention, since the material of the bottom surface of the load receiving portion is such that the curved surface is deformed into a horizontal plane when the panel is placed and lifted, the load of the panel applied to the receiving member is the entire load receiving bottom surface. You will receive it evenly distributed. Therefore, the stress acting on the contact surface of the lower surface of the panel from the bottom surface of the load is not evenly distributed on the entire contact surface and concentrated on only the corners.

[0006]

【Example】

 Embodiments of the present invention will be described below with reference to the drawings. As shown in FIG. 1, the panel hoisting receiving member of the present embodiment includes a cargo receiving bottom surface 7 applied to the short side end of the panel lower surface, a hanging surface 8 applied to the lower edge of the fore edge of the panel, It consists of the bottom surface of the load receiving part and two stopper parts 5 fixed to the inside from the ends of the vertical faces at a substantially right angle.

The pair of receiving members 1 supports both lower edges of the lowermost panel among the plurality of ALC panels 10 stacked as shown in FIG. The pair of receiving members 1 are provided with half-ring-shaped members 6 that lock the lower end of the lifting member 2 at each outer edge portion of the stopper portion 5.

The plurality of suspension members 2 are mainly composed of wires, the ends of which are wound in a U shape through the hollow portion of the semi-ring-shaped member 6 and the ends are fixed to the wire body.

Prior to manufacturing the receiving member of this embodiment, 15 ALC panels each having a long side of 3 m, a short side of 60 cm and a thickness of 10 cm were hung up by using a conventionally used triangular sling. When the value of the curvature of the received metal piece having a thickness of 7 mm at that time was measured, the maximum length of the foot from the curved surface caused by the lifting to the horizontal surface before the bending was 0.3 mm. Therefore, in the present embodiment, a metal having the same material as the metal receiving metal having a thickness of 7 mm used for the conventional triangular sling is used, and the shape of the bottom surface of the cargo receiving side is a convex curved surface, and the deformation caused by the lifting is performed. The maximum length of the foot to the rear horizontal plane was set to 0.3 mm.

As a result, when the panel is hoisted using the receiving member 1 of the present embodiment, the maximum length of the foot is 0 in the downward direction between the fulcrums of both ends of the load receiving bottom surface 7, that is, in the direction opposite to the panel lower surface. Even if a deformation of 3 mm occurs, since the bending of 0.3 mm is given in the direction opposite to the deformation direction, the load receiving bottom surface 7 is deformed to become a horizontal surface by lifting the panel and the load of the panel is supported by the entire surface. become.

Further, as shown in FIG. 4, it is also conceivable that only the upper surface of the cargo receiving bottom surface 7 that abuts on the lower surface of the panel is inflated in a bow shape so that the central portion has a thick shape. However, if the same material as the conventional one is used, the degree of deformation will be reduced by the thickness of the central part, so the maximum foot length will be set to less than 0.3 mm and the bottom 7 of the load receiving surface will be deformed during panel lifting. Care must be taken to make it a horizontal plane.

[0012]

[Effect of the device]

 As described in detail above, according to the present invention, even if the bottom surface of the receiving member of the receiving member is deformed downward between the fulcrums of both ends, that is, in the direction opposite to the lower surface of the panel, the deformation does not occur. Since the curved surface is deformed in the opposite direction, the cargo receiving bottom surface 7 is deformed by the panel hoisting and becomes a horizontal surface, and the weight of the panel can be evenly distributed and supported by the entire cargo receiving bottom surface of the receiving member. Therefore, the load is not concentrated on the corners of the bottom surface of the cargo receiving area, and the stress is not concentrated on the corners of the panel. At the same time, it is possible to prevent the panel corners from being chipped due to stress exceeding the strength of the panel, and to lift and move the panel without causing the panel corners to chip. It has an excellent effect that it can be done.
