Description

[Detailed Description of the Invention] << Industrial field of application >> The present invention is designed to grip a side edge of a horizontally arranged wall panel so that the wall panel stands upright, and the wall panels are sequentially adjacent to and parallel to a wall installation position of a building. The present invention relates to a trolley-type wall panel mounting device suitable for installation in a standing position.

<< Conventional technology >> For example, in a construction site, when a stacked wall panel is gripped one by one from the upper one and vertically erected and set up at a predetermined position in a building, a crane or the like is used. It is common to hang and transport. In this case, when the wall panel is in a standing state and there is a sufficient pace upward, it is possible to easily bring the wall panel into a vertical state by lifting one end portion of the wall panel. However, if there is not enough space, you have to lift the middle part of the wall panel,
Manual assistance is required to bring the wall panel upright.

In addition, depending on the construction site, it may be difficult to install a crane due to space constraints. In order to deal with such cases, in recent years, on a trolley that can move on the floor,
Various trolley-type wall panel mounting devices have been developed that are equipped with a clamp device for gripping the wall panel so that the wall panel can be easily picked up and set up even in a relatively small floor area. 19084, etc.).

However, in the conventional wall panel mounting device, the operation of picking up the upper surface of the wall panel in the horizontally placed state and the operation of vertically raising the wall panel after that are individually performed by different mechanisms. However, the work process also requires two steps, that is, a pick-up operation and a rotation start-up operation, and the work efficiency is reduced accordingly.

Therefore, the applicant has formed a gate shape as shown in FIG.
A base frame 3 in which a carriage 2 which can move freely is provided at the lower end of each of the support columns 1, a pair of parallel support arms 4 attached to each of the support columns 1 of the base frame 3 so as to be vertically movable, and A lifting operation mechanism 5 that lifts and lowers each support arm 4.
And a clamp device 8 that is rotatably attached to each support arm 4 via a horizontal fulcrum pin 6 and that grips and raises opposite side edges 7a of the wall panel 7 in a horizontally mounted state. The position of the center of gripping rotation of the wall panel 7 by the device 8, that is, the position of the fulcrum pin 6 is a constant distance from the compound gravity center position of the clamp device 8 and the wall panel 7 when the wall panel 7 is vertically erected. A wall panel mounting device that has been set at a position that is offset in the direction has already been proposed. (Actual application No. 1-82256 (Act No. 6-7176), etc.). This allows the wall panel 7 to be lifted above the center of gravity as the support arm 4 rises, so that the wall panel 7 is lifted.
With the simple mechanism, the operation of picking up and the vertical standing operation can be performed simultaneously.

<Problems to be Solved by the Invention> However, in the above proposal, as shown in FIG. 6, the center of gripping rotation of the wall panel 7 by the clamp device 8, that is, the position of the fulcrum pin 6 is the thickness of the wall panel 7. Since it is within the range of the direction, when the wall panel 7 is to be erected on the wall installation position of the building in parallel with the side edges sequentially adjacent to each other, the side of the already installed other wall panel 7 ' A gap corresponding to the insertion of the fulcrum pin 6 is required between the edge 7'a and the wall panel 7, so that the fulcrum pin 6 is once removed from the gap, and then the wall panel 7 is laterally shifted to remove the two wall panels. There was trouble, such as having to join the side edges.

The present invention has been made in view of such circumstances, and it is possible to simultaneously perform the operation of picking up the wall panel and the operation of vertically erecting the wall panel simultaneously, and the wall panel is sequentially adjacent to the wall installation position of the building. It is an object of the present invention to provide a wall panel mounting device that can be easily operated even when it is installed upright in parallel.

<< Means for Solving the Problem >> A wall panel mounting device according to the present invention comprises a pair of support arms mounted on a support stand erected on a carriage so as to be capable of moving up and down, and an elevating operation mechanism for elevating the respective support arms, A clamp device that is rotatably attached to each of the support arms and that grips and raises opposite side edges of the wall panel in a horizontally mounted state, the clamp device rotating outward on the surface side of the wall panel. It has a tongue-shaped clamp member that has a moving center position set and can be inserted into and removed from the wall panel front surface side, and an interlocking mechanism that rotates the clamp member in the rising direction of the wall panel as the support arms move upward. It is characterized by

<Operation> When the wall panel is installed in a standing position, the device is first placed near the wall panel in a horizontally mounted state or at a position where it can be straddled, and the support arm is lowered in this state. In this case, the clamp member is directed downward by the interlocking mechanism. Therefore, each clamp member of the clamp device is moved toward the approaching direction, and the side edges of the wall panel facing each other are gripped by the clamp members.

Next, the support arm is lifted by the lifting operation mechanism. When the support arm is lifted, the clamp member is rotated in the rising direction of the wall panel by the interlocking mechanism in association with the lifting operation, whereby the wall panel is erected in a vertical state with the fulcrum pin as the rotation center.

Further, the clamp member of the clamp device has a tongue shape and can be inserted into and removed from the surface side of the wall panel, and the pivot center position is set outside the surface of the wall panel. Not within range of direction. Therefore, even when the wall panel is to be erected in parallel on the wall installation position of the building with the side edges sequentially adjacent to each other, it is simply tongue-shaped between the side edges of the other wall panels already installed. It is sufficient if there is a small clearance for inserting the clamp member. After installing the wall panels, if the clamp members are pulled out from between the wall panels by inclining the clamp members in the thickness direction of the wall panels, etc., both wall panels can be easily installed in a standing state. You can

<< Embodiment >> An embodiment of the present invention will be described below with reference to the drawings.

FIG. 1 shows a schematic structure of a wall panel mounting device according to this embodiment, and FIGS. 2 to 4 show its detailed structure and the wall panel starting operation.

As shown in FIG. 1, a gate-shaped base frame 11 is provided, and the base frame 11 has a pair of right and left vertical support columns 12, and each support column 12 is slidable on the lower cylinder 12a and the lower cylinder 12a. It can be expanded and contracted by the upper rod 12b that is movably inserted. And
The upper rod 12b of each column is vertically driven by the cylinder mechanism 13. Also. The lower ends of the columns 12 are supported on a floor surface 14 by a carriage 15 which is rotatable in any direction.

Support arms 16 each having a substantially L-shaped side face are attached to each of the support columns 12 of the base frame 11 in parallel with each other, and each support arm 16 can be moved up and down by the lift mechanism 17 to each of the support columns 12. The up-and-down operation mechanism 17 is, for example, a wire moving mechanism that uses a wire or the like that responds to the expansion and contraction of the column 12. That is, the wire 18 connected to the support arm 16 is connected to the lower tube 12a of the support column 12 via the sheave 19 at the upper end of the upper rod 12b of each support column 12.
Sheave 19 when it is fastened to the column and the column 12 extends upward.
As the support arm 16 is lifted by the wire 18, the support arm 16 is suspended by the wire 18, and when the support column 12 is contracted downward, the support arm 16 is suspended by the wire 18 as the sheave 19 is lowered.

A clamp device 21 for gripping the wall panel 20 is attached to the tip of each support arm 16. The clamp device 21 is capable of sliding a pair of substantially L-shaped tongue-shaped clamp members 22 each having one piece 22a that grips opposite side edges of the wall panel 20 and the other piece 22b of each clamp member 22. A holding member 23 which is long in the left and right direction and which is provided on the holding member 23, and a cylinder mechanism 24 as a clamp member interval setting mechanism which slides in the opposite direction to adjust the facing gap of the clamp member 22 are provided. At both ends of the holding member 23 of the clamp device 21, bracket portions 25 are provided in a shape bent to the side opposite to the clamp member 22, and the bracket portions 25 are fulcrum pins.
It is supported by the tip of the support arm 16 by 26 so as to be vertically rotatable. As a result, the clamp member 22 of the clamp device 21 has a rotation center position set outward on the front surface side of the wall panel 20, and can be inserted into and removed from the front surface side of the wall panel 20.

Further, an interlocking mechanism that rotates the clamp member 22 in the rising direction of the wall panel 20 as the support arms 16 move up.
27 are provided. This interlocking mechanism 27 includes a support arm 16
It is considered to be a rope moving mechanism that responds to the lifting and lowering of the wire. That is, the upper end of the holding member 23 and the support arm 16
Sheaves 28, 29, 30 are provided on the sheaves 28, 29, 30.
One end of a wire 31 wound around 30 is fixed to one sheave 29, and the other end of the wire 31 is attached to the lower tube 12 of the column 12.
It is attached to a. When the support arm 16 is raised, the sheaves 28, 29, 30 are raised, and the holding member 23 is turned upward by the wire 31, and when the support arm 16 is lowered, the sheaves 28, 29, 30 are lowered. With holding member 23
Is rotated downward by the wire 31.

Next, the creation will be described with reference to FIGS.

When mounting the wall panel 20 on a stand, first of all, the gate-shaped base frame
11 is arranged at a position where the wall panel 20 in the horizontally mounted state can be groined, and the support arm 16 is lowered in this state. in this case,
The clamp member 22 is directed downward by the interlocking mechanism 27. Therefore, each clamp member 22 of the clamp device 21 is moved to the approaching side in the opposing direction, and the wall panel 20 is moved by the clamp member 22.
Grip the opposite side edges of.

Next, the support arm 16 is lifted by the lifting operation mechanism 17. When the support arm 16 is raised, the clamp member 22 is rotated in the rising direction of the wall panel 20 by the interlocking mechanism 27 in association with the raising operation, whereby the wall panel 20 causes the fulcrum pin 26 to move.
Stand upright with the center of rotation as the center of rotation.

Further, the clamp member 22 of the clamp device 21 has a tongue shape,
The pivot point 26 is not within the range of the wall panel 20 in the thickness direction because it can be inserted into and removed from the front surface side of the wall panel 20 and the pivot center position is set outside the front surface side of the wall panel 20. Therefore, even when attempting to hang the wall panel 20 at the wall installation position of the building in parallel with the side edges sequentially adjacent to each other, the space between the side edges of the other wall panels 20 ′ already installed is simply increased. A small gap for inserting the tongue-shaped clamp member 22 is sufficient. Then, after the wall panel 20 is installed, if the clamp member 22 is pulled out from between the wall panels 20 by performing an operation such as slightly tilting the clamp member 22 toward the front surface side of the wall panel 20, the both wall panels 20, 20 'can be easily joined. It can be installed in a standing state.

<Effects of the Invention> As described above, according to the wall panel mounting device of the present invention, the operation for picking up the wall panel and the vertical standing operation can be simultaneously performed by a simple mechanism, and the wall panel can be installed in the building. Even in the case where they are placed adjacent to the wall installation position one after another and stand upright in parallel, the operation can be easily performed.
