The present invention relates to an apparatus and a method for this purpose.

Building materials that can be lifted by the device of the invention include, for example, mineral wool. It has an elastic core made of wool fibers, each flat surface of which is in contact with the surface of the wool plate. It is covered with a worn metal sheet. Do this to prevent damage to the plate. Building materials must be handled carefully, using the well-known clamp jaws. Jaw) type lifting equipment to be used for such plate lifting operations. I can't. For lifting of inherently light plates, suction pads allow members to be A variety of gripping members have been developed that are fixed to the flat surfaces of.

Despite the relatively light weight of the plate to be lifted, it is difficult to In order to ensure safety, and to prevent the adhesion of the suction pad, Considering the influence of factors, a considerable number of suction pads are required. Besides, this The gripping member of the lifting device is designed to fix the gripping member to the flat surface of the plate to be lifted. This requires sufficient free space on at least one surface of the plate.

The above drawbacks can be eliminated by the device and method of the present invention, according to which the It is now possible to grasp the end of the plate, and in some cases it is possible to It is even possible to grip the plate horizontally within a space corresponding to the thickness of the plate.

The main features of the device are set out in claim 1. The main feature of this method is the claim 11.

The invention is illustrated by the accompanying drawings, in which FIG. Fig. 2 shows the first fixing step in which the device of the invention is placed at the upper end of the material; The device of the present invention is fixed in a lifting position to a building material to be lifted as seen from the same direction. Fig. 3 shows the state in which the lift device is in the lifting position at the upper end of the building material when viewed from a flat surface. The present invention for lifting roof building materials is shown in a fixed state and FIG. An example of its application is shown below.

Most of the thickness of the type of plate building material that can be lifted by the device of the present invention is It consists of a core section 8 and plates 9.9° covering both sides of this core section. Ko The a part 8 is made of, for example, a mineral wool mat with appropriate strength, and is made of metal. covered with a sheet.

The upper end of the wall building material in Figures 1-3 is configured to achieve a connecting structure. In other words , each cover plate 9,9° extends slightly above the core portion 8 toward the core portion. A bead that extends along the length of a building material by being bent. is formed. These ribbed edges extend slightly towards the center of the building material. However, most of the upper end portion of the core portion 8 is left in a free state. illustrated In the embodiment, each rib edge has a tongue 10 in the longitudinal direction of the plate. A groove of a shape matching this tongue is formed in the lower end of the adjacent building material.

The roof construction material shown in FIG. 4 differs from the wall construction material described above in the configuration of the connecting end. This building material A plate cover 9 forming the lower surface of the core part 8 is attached to the top of the core part 8 similarly to the wall building material. Although the plate cover 9° that forms the upper surface is partially extended, the plate cover 9° cannot be bent outward. This creates a water seam (w) between two adjacent building material plates. afer seam) is formed. In addition, there is a tongue structure on the bottom surface. dgroovestructure)IO’ is also used for Unlike the furuzuke structure, the furuzuke structure actually has a longitudinal groove at the lower end of the wall building material. It fits better into the structure.

The lifting device of the invention first includes a beam l forming a frame. Wall construction The width of this beam of the lifting device intended for lifting of materials is preferably Consistent with thickness. On the other hand, in the case of a device whose purpose is to lift roof building materials, The width of this frame member is not critical. On the other hand, in the case of a lift device for wall building materials The length of the frame beam l can be freely selected, but in the case of a lift device for roof building materials, The length of the frame beam depends on the thickness of the building material being lifted. frame bee At least one gripping unit constituted by a shaft or similar member 2 is attached to the clamp. The shaft member is preferably formed at the center of the frame beam l in the width direction. It is placed in a through hole. This shaft member 2 has a clearance in the through hole. It is located in a state with a frame beam l, is rotatable relative to the frame beam l, and is It can be moved freely in the direction.

A longitudinal gripping claw 3 is arranged at the other end of the shaft member at right angles to the longitudinal axis of the shaft member. . In the lifting device for wall building materials, the width of the gripping claws 3 is such that the gripping claws 3 are It is arranged in the space left between the protruding edges of 9° and 9°, and is attached to the upper end of the core part The dimensions are such that it can be pressed freely. The length of the gripping claw 3 is When the building material is rotated transversely to the longitudinal direction, at least one trapezoid structure The dimensions are such that it protrudes below the structure 10. However, as shown in Figures 1 and 2 As such, it is preferable that the protrusion edges of both trapezoid structures 10 protrude below. roof building In the case of a material lifting device, the gripping claws 3 are preferably arranged only on one side from the shaft member 2. The length of the protrusion is determined by considering the position of the shaft member 2 and the protrusion of the trapezoid structure lO° on the lower surface of the building material. The dimensions are such that it protrudes below the strip edge.

In the case of a lifting device for wall construction materials, the lower surface of the frame beam l is the upper surface of the construction material to be lifted. It is structured in accordance with.

That is, a longitudinal groove is formed in the frame beam for receiving the tongue 10. roof building In the case of material lifting devices, such tongues and grooves are not required, but instead gripping At the end of the frame beam l with claws 3, the lower surface of the roof building material protrudes on the side of the gripping claws. It is desirable to provide a cam l° that fits into the groove of the trapezoid structure 10'.

In the case of a lift device for roof building materials, one end of the frame beam 1 is attached to the upper surface of the roof building material. A dedicated gripping member 11 for gripping the water seam portion I2 is attached. child The gripping member 11 is formed in a hook shape and is attached to a gripper disposed at the other end of the frame beam. It is fixed to the frame beam l by a shaft member 2 arranged in the same manner as the holding claws 3. grip The holding member 11 is dimensioned so that it can be bent into a hook shape behind the 12° flange edge of the water seam. It is considered a law. Instead of this hook-shaped gripping member 11, it is possible to grip the building material to be lifted. Another type of member, for example, a suction pad that grips the plate 9° forming the surface layer. It may also be provided with a code.

In the lifting device for wall construction materials in Figures 1 to 3, set the lifting device to the lifting position. When doing so, first rotate the gripping claw 3 in the direction of the frame beam l, then rotate the gripping claw 3 in the direction of the frame beam l. 1 on top of the upper end of the building material, as shown in FIG. After this, frame beam The shaft member 2 that protrudes through and the gripping claw 3 at the end of the shaft member 2 is placed on the elastic core layer 8 of the member. press it against the surface.

The elastic core layer is slightly elastically deformed, and as a result, the gripping claws 3 are rotated to a posture in the thickness direction of the building material. pressed into the building material to such an extent that it can be moved. In this position, the claws of the gripping member are As shown in FIG. There is. Then, rotate the lift arm 5 to a position in the direction of the frame beam 1, and It is locked in position within the locking member 6 fixed to the beam l. This lock member preferably also serves as a lifting eye for the device.

In the case of a lifting device for roof building materials, it is placed transversely to the building material to be lifted. , As a result, the above-described gripping member 11 is first fixed with the hook at the flange 12°. It's done in the back. After this, the cam l° of the frame member is pushed into the trapezoid structure of the building material. In rare cases, the shaft member 2 and the gripping claws 3 at the end of the shaft member 2 are elastically connected in the same manner as described above. is pressed against the layer 8, so that the gripping claw 3 is positioned below the protruding edge of the trapezoid structure 10'. The shaft member 2 is then rotated. In the lift device for roof construction materials, instead of the above rotation configuration, It is also possible to use structures such as: That is, in this structure, the shaft member The part corresponding to 2 moves within the slit formed in the longitudinal direction of the frame beam. Ru. In this case, when the gripping claw 3 is pressed against the upper surface of the core part 8, the gripping claw 3 Take the position shown in 4. The claw slides on the lower side of the protruding edge of the trapezoid structure and assumes this position. , is locked in the lift position by the member shown in FIG.

The fixation of the lifting device to the end of the building material to be lifted is ensured by another feature of the invention. considered as something. According to this feature, the hinge between the lift arm 5 and the shaft member 2 A wedge surface of 4° is formed on the member 4 to serve as a clamp member. This wedge surface allows the lift When the arm 5 rotates to a horizontal position, the shaft member 2 can rise slightly, This rise allows gripping of the building material to be lifted, such as the ridged edge of the trapezoid structure or the water seam. Similarly, hold the member between the frame beam 1 and the gripping claw 3 with the frame beam l. It can be sufficiently tightened with the member 11.

A lift device for the purpose of lifting wall construction materials includes the above-mentioned lift member (shaft member 2, gripping claw Preferably, a pair of hinge members 4 and lift arms 5) are provided as shown in Factor 3. These lock members 6 cooperate with each other.

With this configuration, this lift device becomes a device (tool) that operates in an integrated manner. Ru. However, other configurations are of course possible within the scope of the invention, e.g. The equipment is equipped with only one lifting member (lifting 5 units). Good too. Additionally, the dimensions of the lift device may be increased to accommodate two or more lift members. ng 5ubpairs) may be arranged at appropriate intervals.

, the lift device for roof building materials is originally equipped with only the members shown in FIG. 4, and preferably, Use multiple devices to locate the building material to be lifted at multiple distances from each other. You may also choose to hold it.

As a modification of the embodiment described above, instead of the beam-shaped frame 1 described as one piece, Instead, use another type of frame structure, such as a box structure made of board material or a bent board structure. You may also use a structure formed by Using frame structures of various skeleton types It is also possible to

Instead of the shaft member 2 attached to the frame, it is inserted through the frame in the thickness direction. Using an extending and freely formed arm-like member, A gripping claw 3 is directly formed at one end, and a lift arm 5 or equivalent is formed at the other end. It is also possible to form the member directly and configure this arm member to be locked to the frame. good. In contrast to the configuration described above, it is possible to tilt the arm member 2 with respect to the frame. The grip claw 3 of the arm member 2 covers the cover in one inclined position. The gripping claw 3 is pressed against the lower side of the protrusion edge of the cover, and in another inclined position, the gripping claw 3 is pressed against the lower side of the protrusion edge of the cover. Lock the ridge edge of the arm member to the frame, and then lock the opposite end of the arm member to the frame. It may be configured so that This locking of the arm member 2 to the frame is performed as described above. It may also be carried out directly without using a lift arm, in which case e.g. It is locked to the ringlet 6 or elsewhere on the frame.

Instead of or in addition to rotating or tilting the shaft member or arm member 2, this For example, these members may slide in grooves extending through the frame. Good too. This makes it possible to rotate the shaft member 2 and gripping claw 3, for example in FIG. Instead, the gripping claws are pressed against the lower side of the protruding edges of the surface layer. Gripping claw 3 is a ski Designed to facilitate push-in movement and avoid damage to the surface of the core layer. can be done.

As mentioned above, in many applications, gripping only the ridge edge of one surface layer is difficult. The structure formed by the gripping claw 3 or the corresponding arm part 2 is used as a lift device. It is sufficient to have them prepared in advance. The edge of the building material at the opposite end of the lifting device Various methods are possible for supporting the opposite side of the part, an example of which is shown in Figure 4. This is the hook-shaped gripping member 11 shown. Instead of this member 11, other types of gripping parts can be used. It is also possible to use a material such as a suction pad that adheres to the surface layer 9°. surface If the layer 9' extends to the top of the core part 8, first insert it under the ridge edge of the surface layer. For example, a hook-shaped gripping member protruding from the frame 1 to one end thereof may be used as the gripping member. This member can be inserted under the ridge edge formed at 9° on the surface layer. be done. After this, the opposite end of the frame has a functional handle, for example as shown in Figure 4. It is locked under the protrusion edge of the surface layer 9 on the opposite side by the holding claw 3.
