Description

[Detailed description of the invention] (Industrial application field) The present invention is a concrete formwork panel used for wall construction, especially a concrete formwork panel commonly referred to as a large panel.
This relates to a concrete formwork panel support used when supporting a large concrete formwork panel with the height of one floor on an existing wall on the lower layer.

(Prior art and its problems) The concrete formwork panel support used as described above is, for example, disclosed in Japanese Utility Model Application Publication No. 1, No. 59-78456.
As shown in the figure, there is a main body including a wall attachment part and a panel receiving part, a panel receiving screw that is threaded vertically through the panel receiving part, and this panel receiving screw. It consists of a panel pressing fixing screw that presses the panel placed on the upper end panel receiving seat toward the existing wall side, but conventional concrete formwork panel supports of this type do not allow the concrete formwork panel to be It was not possible to support the panel at a sufficient distance from the existing wall surface. Therefore, when attaching tiles to the concrete formwork panel first, it is not possible to separate the concrete formwork panel sufficiently from the column when attaching the tiles to the concrete formwork panel part adjacent to the column. The problem was that the reinforcing bars got in the way, making it very difficult to install the tiles in advance.

In order to eliminate such drawbacks, it has been considered to provide a panel support part that supports the panel so that it can slide in the front and back direction outside the upper end panel receiving seat of the panel receiving screw, but in this case, the panel support part In order to press and transfer the upper panel onto the panel receiving seat using the panel pressing and fixing screw, the panel receiving seat is set at a lower lower limit height than the panel supporting portion, and the panel receiving seat is set at a lower lower limit height than the panel supporting portion. The level of the panel must be adjusted by raising the panel receiving seat using the panel receiving screws from the state where the panel is placed on the seat. In other words, the level adjustment work performed by rotating the panel receiving screw cannot be performed in an unloaded state where the panel does not receive any load, so not only does it require a very large rotational operating force, but it can also be done safely and efficiently. Unable to perform the relevant work.

(Means for Solving the Problems) The present invention aims to provide a concrete formwork panel support that can solve the conventional problems as described above. A main body comprising a panel support section and a panel support section, a panel support member that is long in the front and rear horizontal direction and supports a concrete formwork panel so as to be slidable in the front and rear directions, and a panel placed on the panel support material. and a panel pressing fixing screw that presses toward the front end of the panel, and both front and rear ends of the panel receiving material can be raised and lowered by two front and rear height adjustment screws that are threaded through the panel receiving portion of the main body. The point is that I supported it.

(Example) An example of the present invention will be described below based on the attached illustrative drawings.

In FIGS. 1 to 3, reference numeral 1 denotes a main body, which is shaped like a shelf holder and is composed of a wall attachment part 2 and a panel holder part 3. 4 is a panel support member long in the front and rear horizontal direction that supports the concrete formwork panel 5 so as to be slidable in the front and rear directions;
It is supported by the panel receiving portion 3 of the main body 1 by two height adjusting screws 7a, 7b that thread through nut members 6a, 6b fixed to the front and rear of the panel receiving portion 3 at two locations. Reference numeral 8 denotes a panel receiving member detachment preventing member that penetrates the panel receiving portion 3 so as to be able to rise and fall and is provided with a retaining flange 8a at the lower end, and the upper end thereof is attached to the panel receiving member 4 with a pin 8b.
It is locked by. Reference numeral 9 denotes a screw for pressing and fixing the panel, which screws through the member 10 connected upwardly from the outer end of the panel receiving portion 3 of the main body 1 in the front-rear direction, and has a disc spring 9a for pressing the panel at the inner end. Rotatably mounted.

To explain how to use it, as shown in FIG. 2, attach the attachment part 2 of the main body 1 near the upper end of the existing wall surface 11, and insert the anchor 12, the bolt 13 that can be screwed into the anchor 12, and the attachment hole provided in the attachment part 2. (See Fig. 1) Use 14 to secure it. Next, the height of the panel support material 4 is adjusted by raising and lowering the height adjustment screws 7a and 7b together with other panel supports installed at approximately the same level, and then the concrete formwork panel 5 is moved to the panel support. Place it on the material 4.

If tiles are to be attached to the concrete formwork panel 5 first, the panel press fixing screws 9 should be retracted to the retract limit as shown in the figure, and the concrete formwork panel 5 should be moved as far as possible from the panel receiving material 4. By placing it near the rear end, it is possible to pre-install the tiles without being disturbed by the reinforcing bars 15 of the column.

The concrete formwork panel 5 placed on the panel support material 4 is attached to the end plate spring 9a of the panel press fixing screw 9 and the concrete formwork panel 5 as necessary.
The panel pressing and fixing screws 9 are rotated and advanced with the square flap material 16 interposed between them, and the concrete formwork panel 5 is pushed forward by the panel press and fixing screws 9 and attached to the existing wall surface 11. Move it until the bottom edge of the panel touches it.

In the embodiment shown in FIGS. 1 to 3, the height of the pressing action of the screws 9 for pressing and fixing the panel against the concrete formwork panel 5 changes by adjusting the height of the panel receiving material 4. As shown, a member 10 for supporting the panel pressing and fixing screw 9 can be provided to protrude from the rear end of the panel receiving member 4.

(Operations and Effects of the Invention) According to the concrete formwork panel support of the present invention, which can be implemented as described above, the concrete formwork panel is long in the front-rear direction and can be raised and lowered as a whole using height adjustment screws. Since tiles can be supported by adjustable panel supports, when installing tiles on a concrete formwork panel, the concrete formwork panel should be supported at a sufficient distance from the existing wall surface and the tiles can be installed in advance. Moreover, even in this case, the height adjustment of the panel support material can be done in advance in an unloaded state where the concrete formwork panel is not supported, so the concrete formwork panel The height adjustment can always be done easily, safely and efficiently. In other words, both the front and rear ends of the panel receiver, which is movably arranged on the panel receiver of the main body, are supported by the two front and rear height adjustment screws, so that the panel receiver is not shown in the figure. It was possible to obtain the above-mentioned effects by configuring the concrete form panel to be long, several times as thick as the concrete formwork panel.
