Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a panel catcher for supporting the lower end of a formwork panel.

As a construction method used when constructing walls, columns, etc. that have a steel-framed reinforced concrete structure or reinforced concrete structure and whose surfaces are finished with tiles, tiles are pasted on the inner surface of the form panel in advance and concrete is poured. A construction method is known in which these tiles are integrally attached to a concrete frame.

When constructing an exterior wall using the above-mentioned construction method, a formwork panel support jig called a panel catcher is usually used.

The case of constructing an exterior wall using the panel catcher will be explained with reference to FIGS. 1 and 2. In FIG. 1, reference numeral 1 indicates the already constructed exterior wall, 2 indicates an external scaffold, and 3 indicates a formwork panel. , 4 indicate panel catchers, respectively.

As shown in FIG. 2, the panel catcher 4 includes a vertical portion 6 having a bolt insertion hole 5, a horizontal portion 7 extending perpendicularly from the upper end of the vertical portion 6, and an upper portion extending upward from the tip of the horizontal portion 7. vertical portion 8 extending to
and a press plate 9 screwed onto the horizontal part 7 and at the tip.
The bolt 10 is rotatably attached to the bolt 10, and the bolt 12 is screwed into the vertical portion 8 and has a press plate 11 rotatably attached to the tip thereof.

When constructing an exterior wall using the conventional panel catcher 4 described above, the panel catcher 4 is first fixed to the exterior wall 1 via bolts 13 and nuts 14. Next, the form panel 3 used in constructing the outer wall 1 is lifted upward using a crane or the like, and then the same form panel 3 is placed on the panel catcher 4 fixed to the outer wall 1. At the same time,
The upper end is placed in an inclined state by leaning against the external scaffold 2 (see Fig. 1). Next, after affixing tiles 15 to the inner surface of this formwork panel 3 in the inclined state, this formwork panel 3 is placed vertically and the formwork panel 3 is placed on the inside of the same formwork panel 3 (on the right side in the figure). An inner formwork panel (not shown) is placed facing the formwork panels, and concrete is poured between these formwork panels.

By the way, when constructing an exterior wall using the conventional panel catcher 4 as described above, when constructing a normal exterior wall that does not have columns etc. on the inside, it can be constructed by the method described above. However, when constructing an exterior wall with columns on the inside, the main reinforcements 16 and hoop reinforcements 17 placed in advance will get in the way, so the tiles 15 cannot be placed inside the form panel 3 in the state shown in FIG. There was a problem in that it was not possible to secure a working space for pasting, and therefore construction could not be carried out using the method described above. For this reason, conventionally, when constructing an exterior wall with columns on the inside, a corbel 18 is provided in advance on the outside part of the column C.
A method has been adopted in which a formwork panel 3 is temporarily placed on top of the tile and a tile 15 is pasted thereon, and then the formwork panel 3 is moved onto a panel catcher 4 and set at a regular position.

In this way, when constructing an exterior wall using the conventional panel catcher 4, when constructing an exterior wall with pillars C on the inside, a new
8 and resetting the form panel 3 moved onto the support 18 onto the panel catcher 4, these operations are extremely troublesome and prolong the construction period. There were other drawbacks.

This invention was developed in view of the above circumstances, and there is no need to provide a special corbel, and tiles can be pasted by simply moving the formwork panel to the end of the horizontally extending overhang. The object of the present invention is to provide a panel catcher that can easily secure a work space for the work and shorten the construction period. The panel catcher according to the present invention has a vertical part that is fixed in contact with the upper side of the already cast foundation or wall, and a vertical part that extends perpendicularly from the upper end of the vertical part and has a It is provided at a horizontal overhang on which a formwork panel and a work scaffolding board are placed at the same time, and at a side that intersects with the vertical part of the horizontal overhang, and supports the lower end of the formwork panel and moves in the vertical direction. It is characterized by comprising a support plate and a pressing plate that moves horizontally orthogonally to the horizontal extension and presses the formwork panel.

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

FIG. 3 shows a panel catcher according to the present invention. This panel catcher 21 includes a vertical portion 22 that is fixed in contact with the upper side of the outer wall, a horizontal projecting portion 23 that extends perpendicularly from the upper end of the vertical portion 22, and a tip of the horizontal projecting portion 23. Reinforcing inclined portion 2 connecting the lower end of the vertical portion 22
The main component is a support consisting of 4.
The support has a structure in which multiple channel steels are joined by welding.

At the intersection of the vertical portion 22 and the horizontal projecting portion 23, a fixed member 25 made of angle iron is provided.
is fixed perpendicularly to each of these parts 22 and 23, and a bolt insertion hole 26 is bored in the vertical surface of this fixed member 25.

On the other hand, a formwork panel support part 27 that supports the lower end of the formwork panel 3 is provided at one end of the horizontal projecting part 23 and intersecting with the vertical part 22 . This formwork panel support section 27 includes a bracket 28 with an L-shaped cross section that is detachably attached to the horizontal extension section 23 via bolts 28a.
A bolt 30 is screwed into the vertical part of the bracket 28 so as to be perpendicular to the vertical part, and a press plate 29 is rotatably attached to the tip thereof, and A bolt 32 is screwed together with the bolt 32 passing through the horizontal upper surface and the horizontal projecting portion 23, and a support plate 31 is rotatably attached to the tip.

Further, the length of the horizontal projecting portion 23 is set to be, for example, 500 mm or more so as to secure a work space for pasting tiles, and a formwork panel 3 and a work scaffold are provided on the top of the horizontal projecting portion 23 as shown in FIG. The plate 33 can be placed at the same time.
Note that 34 is a stopper that determines the movement limit position of the formwork panel 3.

Next, a case will be described in which an outer wall is constructed using the panel catcher having the above configuration. First, as shown in FIG. 4, a plurality of panel catchers 21 are fixed to the upper side of the existing outer wall 1 at predetermined intervals with bolts 13 and nuts 14, and then the fixed panel catchers 21 are The formwork panel 3 is temporarily placed vertically on the horizontal projecting portion 23 in contact with the stopper 34. Next, a scaffolding board 33 is fixed on the horizontal overhanging part 23 of the panel catcher 21 and inside the formwork panel 3, and a worker stands on this scaffolding board 33 to remove the temporarily placed formwork panel 3. The work of pasting the tiles 15 on the inner surface is performed. At this time, the bracket 28 is attached to the scaffolding board 3.
3, it may be removed by unscrewing the bolt 28a.

When the work of pasting the tiles 15 is completed, the scaffolding board 33 is removed, the formwork panel 3 is shifted to the right as shown by the arrow in FIG. 4, and placed on the formwork panel support part 27. It is used as formwork for the outside of the exterior wall (see Figure 5). On the other hand, an inner formwork panel (not shown) is placed inside this formwork panel 3 in a state facing the same formwork panel 3, and concrete is poured between these formwork panels.

In addition, in the above embodiment, the case where an intermediate floor is constructed is explained as an example, and the panel catcher 21 is attached to the outer wall 1 of the lower floor that has already been constructed. Without limitation, it can be attached to the foundation in cases such as when building the lowest floor.

As explained above, the present invention has a horizontal overhang that can secure not only a space for temporarily placing formwork panels but also a work space for pasting tiles. Even if the tile is installed, there is no need to install a new support or move the formwork panel onto the support, just move the formwork panel to the tip side while it is placed on the horizontal overhang. Therefore, the tile pasting work can be shortened, and the entire construction work can be shortened.
