Description

[Detailed description of the invention] The invention has a pair of formworks facing each other for pouring concrete, at least one of the formworks is inclined, and a This invention relates to a butterfly material support fixture for fixing a vertical butterfly material so that its upper part intersects with a support provided on the outside of the other formwork.

As is well known, formwork is used when concrete is poured.

The formwork is held in place by rods called buffing materials.

However, for example, as shown in Figure 1, when one formwork a must be installed at a certain angle, the formwork is supported by buffing material during construction, and the buffing material is placed at a predetermined angle. In order to hold the formwork at an angle, it is connected to the support C installed diagonally from the outside of the other formwork at its upper end A, thereby holding formwork A at a predetermined angle, and then connecting both formworks with a connecting fitting. I was doing work such as.

The work of joining the bar-shaped buffing bars and the bar-shaped supports C in this way is extremely troublesome, and since the buffing bars are provided at regular intervals, construction takes a considerable amount of time, reducing work efficiency. I felt bad.

Furthermore, since a considerable force is applied to the buffing material during the connection, a simple material will not have sufficient strength.

For example, as described in Japanese Utility Model Publication No. 48-20900, if the buffing material is simply surrounded and fixed with metal fittings, the metal fittings will slide and the strength will not be sufficient.

SUMMARY OF THE INVENTION Accordingly, an object of the present invention is to provide a buffing material support fixture that can be easily connected to the upper part of the buffing material to the support, which can be easily removed, and whose angle can be adjusted.

According to the present invention, a pair of side walls and a bottom wall sandwiched between the side walls are bent into a substantially U-shape, and a through hole is formed in the bottom wall, and a through hole is formed in the bottom wall. The provided connecting means connects the other butterfly material support and fasteners so that they can rotate back to back, and the pair of side walls has a length into which a wedge is driven for tightening or fixing the buffing material or support material. A hole is formed, and the bottom wall is formed with sawtooth-like locking means toward the space.

Therefore, by fitting one of the metal fittings into the buffing material and inserting a wedge into the waist elongated hole, the metal fitting and the buffing material can be combined, and since the locking means bites into the buffing material, they can be integrated.

Then, the other metal fitting may be rotated at a predetermined angle with respect to the one metal fitting and fixed with a bolt, and the support column may be similarly fixed with a wedge.

Therefore, the connection can be made by simply driving a wedge into a long hole.

Moreover, since one metal fitting and the other metal fitting are rotatable, they can be adjusted according to the intersecting angle between the buffing material and the support.

Since the locking member bites into the buff material and the support by driving the wedge, the metal fittings do not shift and can be integrated with sufficient strength.

It can be easily disassembled by removing the wedge.

In order to prevent the wedge from being lost when implementing the present invention, it is preferable that the wedge is connected to the stopper body with a flexible string such as a chain.

Embodiments of the present invention will be described below with reference to FIGS. 2 and 3.

The butterfly material supporting and fastening fittings 1 according to the present invention are used as a set of two as shown in FIG. 3, one of which is shown in FIG.

As shown in FIG. 2, the fastener 1 has a pair of side walls 2 and 3 facing each other and a bottom wall 4 sandwiched between the side walls, which are made of a single sheet of steel, for example, in a substantially U-shape. The walls 2, 3.4 are bent, and a buffing material or a support is inserted and fixed into the space formed by the walls 2, 3.4.

As mentioned above, the fasteners 1 are rotatably connected back to back (see Fig. 3), and for this purpose, the bottom wall 4 is provided with a through hole 5, and the side walls 2 and 3 are provided with buffing material. Alternatively, elongated holes 7 and 8 for driving wedges 6 are bored at an appropriate distance from the bottom wall 4 in consideration of the size of the support.

A bata material or support is inserted into the space A, and the wedge 6 is inserted into the long hole 7.
, 8, the stopper 1 is fixed to the batten material or the support, but in order to further strengthen this fixation, the bottom wall 4 is provided with a locking means facing toward the space A. For example, a sawtooth shape 9 that bites into the buffing material is formed.

Furthermore, the ends of the side walls 2 and 3 of the fastener 1 are bent outward to facilitate insertion of the batten material or strut, and at the same time to improve strength.

The wedges 6 driven into the elongated holes 7 and 8 of the side walls 2 and 3 are made of a copper plate like the stopper, but as shown in the figure, they are connected to the stopper 1 with a chain-like string 10. , which helps prevent loss.

Since the butterfly material supporting fastener according to the present invention is constructed as described above, when using it, the two fasteners 1 should be placed so that the bottom wall 4 is facing back to back as shown in FIG.
are rotatably connected by a connecting means 11 such as a bolt or nut, a buffing material b (indicated by chain lines in FIG. 3) is attached to one stopper, and a support (not shown) is attached to the other. By inserting the waist wedges 6 into the respective elongated holes 7 and 8 to appropriate positions, the buffing material and the support column C (see FIG. 1) are connected with the fasteners so that the angle can be adjusted freely.

Therefore, as shown in FIG. 1, the concrete formwork a can be easily constructed at any angle of inclination.

When disassembling concrete after it has been constructed, it is best to perform the operations described above in reverse.

As explained above, according to the present invention, the buffing material and the column are connected in an adjustable angle by the extremely simple operation of driving a wedge, and the concrete formwork can be easily constructed at any angle. That's what you get.

Furthermore, when the wedge is driven in, the butterfly material or support is firmly fixed to the stopper, and since the sawtooth-like locking means is provided on the bottom wall, the connection is made even more firmly.

As mentioned above, the butterfly support and fasteners have various superior effects compared to conventional ones.

Another advantage is that the entire structure can be press-formed from a sheet material such as a steel plate at low cost.
