Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a formwork panel for forming a concrete wall, and to an improvement of a fixed frame for a pier attached to the formwork panel.

[0002]

2. Description of the Related Art Recently, concrete formwork panels have been mounted to reinforce formwork panels for the purpose of reducing the cost of the formwork panel by improving the weight and durability of the formwork panel and by repeatedly using it. The fixed frame for the used piers has been changed from conventional wood to aluminum. The fixed frame made of aluminum has an L-shaped cross section, and is attached to a frame panel of a normally rated size by bolting or screwing.

[0003]

By the way, in order to assemble a concrete formwork at a construction site, a plurality of formwork panels are horizontally connected and each edge is integrated by adjacent fixed frames. Although it is assembled into a wall with the whole structure, when removing the frame after hitting concrete, if there is an obstacle on the floor in front of the frame panel when removing the framed form panel, aluminum fixing The veneer plate may not be removed without removing the frame.At this time, the aluminum fixed frame is bolted or screwed, so the bolts or screws must be removed one by one, which is troublesome. The work efficiency was inferior.

Further, since there is a protrusion such as a pillar in the middle, it is less likely that the formwork panel will fit in the corner of the pillar or the wall, and the width will be narrower at almost the corner than a single formwork panel. There is room for Therefore, when the formwork with the rated size cannot be used, it is often the case that the veneer plate without the fixed frame is cut to the required width to adjust the dimensions. In addition, it is necessary to attach a fixed frame made of aluminum to the edge position according to the cutting width of the veneer plate.

However, the aluminum fixed frame must be bolted or screwed, and when veneer plates having different widths are required depending on the location, the aluminum fixed frame is bolted or screwed to these veneer plates one by one. Therefore, the work is extremely troublesome and time-consuming, the work on site is significantly delayed, and the work efficiency is poor. Therefore, an object of the present invention is to provide an aluminum fixing frame for a pier that solves such problems.

[0006]

In order to achieve the above object, the present invention is a frame for a stake that is fixedly adhered along the longitudinal direction of a concrete formwork panel and is supported on the surface of the formwork panel. A side is provided upright, a storage groove having a wider width in the inner side than the outlet is formed along the inner longitudinal direction of the supporting side, and wood or the like can be nailed in the storage groove. It is composed of a packing material.

[0007]

[Function] A fixing frame for a tree is brought into contact with the front surface of the veneer plate constituting the form panel along the longitudinal direction thereof, and a plurality of nails are hammered at appropriate intervals from the rear surface, and the tips are stored through the outlet portion. Holding the wood in the groove Fixes the frame for the pier by piercing the material. Also, since it is nailed, the frame for the pier can be easily removed from the plywood board by using a bar or the like.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of a pier fixed frame A in a concrete form panel of the present invention will be described below with reference to the drawings.
1 and 2 show a fixed frame A for a wooden pier made of an elongated aluminum.
And a form panel P cut into a suitable width as shown in FIG.
The veneer plate B is attached and fixed along the longitudinal direction of both sides.
In the figure, reference numeral 1 denotes a supporting side portion which is erected perpendicularly to the veneer plate B, and the outer central portion is recessed to provide a recessed portion 2 and upper and lower portions are formed with receiving portions 3a and 3b. In addition, the recessed portion 2 is provided with a plurality of insertion holes 4 through which fasteners (not shown) for continuously fixing the adjacent form panel panels to each other are formed at appropriate intervals along the longitudinal direction.

Therefore, a protruding side portion 5 perpendicular to the supporting side portion 1 is provided inside the supporting side portion 1, and a bent side portion substantially parallel to the supporting side portion 1 is provided at the tip of the protruding side portion 5. 6 is integrated,
The supporting side portion 1, the protruding side portion 5, and the bent side portion 6 form a storage groove 7 along the longitudinal direction. The storage groove 7
The inner sides of the bent side portion 6 and the supporting side portion 1 facing the bent side portion 6 are tapered surfaces 8 and 8 narrowed toward the outlet portion 7a so that the width of the inner portion 7b is wider than that of the outlet portion 7a. It is formed. Then, the holding material 9 which can be nailed is packed in the storage groove 7. In this embodiment, as the holding member 9, a slender timber having the same cross section as the storage groove 7 is inserted.

FIG. 3 shows a formwork panel P in which a wooden frame A made of aluminum is attached and fixed along both side edges of one side surface of a veneer plate B cut to an appropriate width. D indicates a horizontal fixed frame. Figure 6
Shows a plan view showing the outline of the construction site. As shown in the upper left part, _three formwork panels P ₁ , P ₂ , P ₃ having the rated dimensions are connected in parallel, and the formwork panel P is interposed between them. is there. Furthermore,
Although not shown, each form panel P, a long auxiliary plate laterally are connected to the lower edge of P ₁ to P _3. Form panel P ₁ , P ₂ ,
P ₃ is a conventional timber fixing frame O having an L-shaped cross section, and is bolted 13 to each. And FIG.
As shown in Fig. ₁₀ , the right end of the form panel P1 and the left end of the form panel P are aligned, and the receiving portions 3a, 3a and the receiving portions 3b, 3b of the aluminum frame fixing frames O and A are brought into contact with each other. Then, the fasteners are inserted into both the insertion holes 4 and 4 and are connected and fixed to each other. The same applies to the left end of the formwork panel P. Further, at the time of removing the frame, since the frame A for frame P is fastened with the nail N, the frame A can be easily removed by prying with a bar or the like, and the plywood B can be easily removed by removing the auxiliary plate.

Further, form panels of P _{4 and} later are sequentially connected in parallel on the surface of the pillar Pi. At this time, the form panel P ₃
When a gap S shorter than the width of the formwork panel P ₃ is left between the right end face of the column and the left end face of the pillar Pi, the veneer plate B is cut in accordance with the gap S as shown in FIG. Form panel P

Install by hitting nail N through. In addition, the fixing frame A ′ for the pier shown in FIG. The fixed frame A'for the pier is slightly different from the fixed frame A for the pier shown in FIG. 1, and in this embodiment, the supporting side portion 1 is provided in parallel with the protruding side portion 5 via the extended side portion 10, The extension side portion 10 is formed by penetrating an insertion hole 11 into which a nail is driven. The other structure is the same as the fixed frame A for the pier. And the formwork panel Ps
From the above, a nail N is driven into the holding member 9 in the storage groove 7. Since the storage groove 7 is narrowed toward the outlet portion 7a side, the holding member 9 inside does not come out, and the fixing frames A and A'for the pier are firmly fixed by the nail N.

As shown in FIG. 8, the formwork panel Ps is arranged between the formwork panels P ₃ and P ₄ , and the fixed frame O for the pier on the right end of the formwork panel P ₃ and the left end of the formwork panel Ps. The fixing frames A are brought into contact with each other, and the fasteners are inserted into the respective insertion holes 4 and 4 provided in the supporting side portions 1 of the two fixing frames O and A for the piers to form frame panels P ₃ and Ps.
Connect and fix. In addition, the fixed frame A'for the pier is the extended side portion 1
