Description

[Detailed description of the invention] The present invention relates to a concrete formwork support fitting, which supports concrete formwork that is erected oppositely when constructing a wall by pouring concrete on a concrete foundation or concrete wall. Concerning concrete formwork support fittings used as means.

Conventionally, regarding this type of metal fittings, for example, the architectural pier fastening metal fittings according to Japanese Utility Model Publication No. 1222/1983 shown in Fig. Washer 10
1 was fixed, and a formwork 103 and a horizontal butterfly 104 were placed and fixed on a rising part 102 connected to the upper end of this washer 101. However, such conventional products do not have a means for supporting and fixing the vertical flaps arranged in an intersecting manner on the horizontal flaps 104, and it is also necessary to temporarily form the rising portion 102 wide so that the vertical flaps and the horizontal flaps 104 can be mounted. Even if it were possible to install this type of metal fittings, it would be necessary to prepare these types of fittings for each building that will be installed in large numbers.
Not only is it uneconomical, but it is also troublesome to install, and there is a risk of lowering work efficiency.

The present invention was devised to improve the shortcomings of the conventional products, and its gist is that a fixed plate is fixed vertically to the side of the concrete foundation, and the upper end of this fixed plate is attached to the concrete foundation. An upper mounting table is arranged horizontally in a direction away from the upper mounting table, on which the formwork and the vertical and horizontal flaps that press the formwork are simultaneously placed, and an upper mounting table is connected to the lower end of the fixed plate so as to face the upper mounting table in substantially parallel relation to each other. a lower mounting table for placing and holding a receiving batter for receiving the building batter; a receiving piece connected upwardly at the tip of the upper placing table; It consists of a tightening bolt that presses and fixes the flaps and horizontal flaps in the direction of the concrete foundation.

Hereinafter, one embodiment of the present invention will be described based on FIGS. 2 to 4.

In the figure, 1 is a fixed plate, which is fixed vertically to the side of the concrete foundation F.
A groove 2 in the opposite direction is further formed in the steel plate having a groove-shaped cross section, and an elongated mounting hole 3 is bored in the upper part of the groove 2.

The groove portion 2 is formed so as to have a deep bottom toward the top, and has sloped sides (see FIG. 4).

In addition, in the figure, reference numeral 4 denotes an upper mounting table that is installed horizontally in the direction away from the concrete F at the upper end of the fixing plate 1, and has a groove 2 like the fixing plate 1. Spacer 5 is fitted.

A substantially triangular steel plate attached at a location where the upper mounting table 4 and the fixing plate 1 are connected is a reinforcing portion 6 that reinforces the upper mounting table 4.

At the tip of the upper mounting table 4, there is a receiving piece 7 extending upward.
A tightening bolt 8 is screwed into the receiving piece 7 toward the concrete foundation F. The tightening bolt 8 has a substantially disk-shaped stop portion 9 at one end located on the side of the concrete foundation F.

At the lower end of the fixed plate 1, a lower mounting table 10, which is approximately half the length of the upper mounting table 4 and facing approximately parallel to the upper mounting table 4, is installed in series. A stopper piece 11 is fixed to the tip.

Next, to explain the use of the present invention, as shown in Fig. 2, first, set the separator S buried in the concrete foundation F so that it is inserted into the mounting hole 3, and then attach the home tie to the separator S. (registered trademark) 12 is screwed in and tightened to fix it in a predetermined position in the vertical direction. At this time, since the attachment hole 3 is formed into a long hole, the fixing position can be finely adjusted. In addition, HomeTie (registered trademark) 1
Nuts or other fasteners may be used instead of 2. The formwork 13, the rectangular cylindrical vertical butterfly 14, and the horizontal butterfly 15 are placed on the upper mounting table 4 at the same time, and these are tightened with the tightening bolts 8.
The formwork 13, the rectangular cylindrical vertical butterfly 14, and the horizontal butterfly 15 are pressed toward the concrete foundation and completely fixed.

In this case, a stable fixed state is maintained by the action of the stopper portion 9. On the other hand, even if the outer part of the fixed plate 1 and the upper mounting table 4 that are connected to each other is curved, the formwork 13 is placed on the spacer 5 because the spacer 5 is fixed in the groove 2. The solid and stable immobilization is achieved by placing the sample in place (see Fig. 4).

In the illustrated example, a part of the lower ends of the two double-sided butterflies 14 are placed on the upper mounting table 4;
The width of the upper mounting table 4 may be made wide so that the entire lower end of the upper mounting table 4 can be placed thereon.

On the other hand, a receiving butter 16 is placed on the lower mounting table 10, and this receiving butter 16 is horizontally suspended between another lower mounting table 10 located at a predetermined interval.
Place the stand 14 on top. The receiving butter 16 is prevented from falling off by the retaining piece 11,
By forming a receiving piece 7 and a tightening bolt 8 in the same way as the upper mounting table 4 instead of this stopper 11, the receiving butter 1
6 may be completely fixed. Although a large load is applied to the fixed plate 1 and the upper and lower mounting tables 4 and 10, the overall robustness is sufficiently maintained by forming the groove portion 2 and the reinforcing portion 6.
The home tie 12 is formed with an inclined side surface.
There is no possibility that the fixing plate 1 will slip down after tightening.

Therefore, according to the present invention, concrete foundation F
A fixing plate 1 is fixed vertically to the side surface of the fixing plate 1, and a formwork 13 and a building butter 14 that holds down the formwork 13 and a horizontal The upper mounting table 4 on which the butterfly 15 is placed simultaneously, the receiving piece 7 that is connected upwardly at the tip of the upper mounting table 4, and the receiving piece 7 is hinged to hold the formwork 13 and the standing butter 14. and the horizontal butterfly 15 in the direction of the concrete foundation F, so that the fixing plate 1 can be fixed to the separator S and attached to the concrete foundation F, and the mold can be placed on the upper mounting table 4. Frame 13, height 14,
By placing the horizontal flaps 15 and tightening them with the tightening bolts 8, the entire formwork 13 can be firmly fixed and supported.

In addition, since the fixed plate 1 has a lower mounting table 10 which is arranged in series so as to face the upper mounting table 4 substantially parallel to the lower end thereof, and which places and holds the receiving butter 16 for receiving the raised butter 14, the metal fitting according to the present invention is provided. After attaching a plurality of holders, if the receiving butter 16 is placed horizontally between each lower mounting table 10, the standing butter 14 located between them can be placed on the receiving butter 16. Therefore, it is not necessary to attach this type of supporting metal fittings to each of the building blocks 14, and not only can work efficiency in formwork work be expected to be improved, but also the number of metal fittings used is small, which is extremely economical.

Since the fixing plate 1 is vertically fixed to the concrete foundation F by the separator S buried in the concrete foundation F, the support plate 1 is fixed on the support plate 16 placed on the lower mounting table 10. The lower end portion of the frame 14 is located below the lower end of the formwork 13 and the separator S, and the vertical butterfly 14 is located below the horizontal butterfly 15 located at the bottom.
Since the formwork 13 is firmly clamped by the concrete members, it is possible to strengthen the lower end of the formwork 13, which is subject to the strongest lateral pressure due to the load of concrete pouring, and to maintain the erected state of the formwork 14 itself. Stabilization can be achieved.

As explained above, the present invention has various practical effects such as firmly fixing and supporting formwork used during concrete pouring.
