Description

[Detailed Description of the Invention] [Industrial field of application] The present invention relates to a form supporting material used when supporting an outer surface of a concrete form by pressing it.

[Conventional technology]

When supporting a concrete formwork with a required support, it has been conventionally practiced to interpose a steel pipe end thick material between the support and the formwork.

[Problems to be solved by the device]

The above steel pipe end thick material is only interposed between the mold and the support, and cannot be fixed by means for integrating with the mold, for example, by nailing. Therefore, there is a problem that the positioning becomes inaccurate. In addition, there is also a drawback that the steel is heavy due to its characteristics.

On the other hand, wood shavings have been used for a long time as formwork support materials, but due to their lack of durability, they cannot be used repeatedly over a long period of time, and in recent years they are more expensive than steel products. There is.

Therefore, an object of the present invention is to provide a lightweight and inexpensive form supporting material which can be nailed.

[Means for Solving the Problems]

In order to achieve the above-mentioned object, the present invention is constructed by combining a main member 1 made of aluminum and an auxiliary member 2 made of wood in a form supporting material having a required length having a square cross section as a whole. The main body 1 forms a central body portion 3 over the entire length, four corner portions 4 are integrally provided at the four corners of the central body portion 3, and the outer surfaces 5 and 6 intersecting the four corner portions 4 at 90 degrees, Inner side surfaces 7 and 8 that intersect the outer surfaces 5 and 6 at 90 degrees are formed, and grooves 9 are formed by the inner side surfaces 7 and 8 facing each other at each of the four corners 4 and the body portion 3. Of these grooves 9, The outer surfaces 5 and 6 of the four corners 4 and the auxiliary member 2 having a uniform height are fitted and integrated into at least two grooves 9 that face each other across the body 3.

[Action]

The above-mentioned formwork support material is integrated with the formwork 11 by applying the surface into which the auxiliary member 2 is fitted to the surface of the concrete formwork 11 and driving the nail 12 from the back surface of the formwork 11 to the part of the auxiliary member 2. Plan. The support plate 14 of the support 13 is applied to the surface on the side opposite to the above, and nails 15 are driven from the support plate 14 into the portion of the auxiliary member 2 to be fixed as necessary.

〔Example〕

The formwork support shown in the accompanying drawings generally has a square cross section similar to that of a conventional steel pipe end thick material. This form supporting member is composed of a combination of a main member 1 made of an extruded aluminum member and an auxiliary member 2 made of wood.

The main member 1 has an overall center and a body portion 3. In the case of the figure, the body 3 has a cross-sectional shape of four trapezoids arranged at diagonal positions, and the lower end of the hypotenuse of each trapezoid is continuous with each other. The four corners 4 of the modified pentagon are integrally formed at the four corners of the body 3, that is, the top of the trapezoid.

Each of the four corners 4 forms two right-angled portions of the entire formwork support, two outer surfaces 5 and 6 that intersect at 90 degrees, and an inner surface 7 that intersects each outer surface 5 and 6 at 90 degrees. 8 and the trapezoidal apex described above and an integral slope 17.

As a result of such four corners 4 being formed at the four corners of the body 3,
A portion surrounded by the inner side surfaces 7 and 8 of each of the four corner portions 4 facing each other and the wall of the body portion 3 becomes a groove 9 extending over the entire length.

One such groove 9 is formed on each of the upper and lower surfaces and the left and right surfaces that face each other.

The auxiliary member 2 is formed in a rectangular cross section so as to fit snugly in the groove 9 and is fitted in each groove 9 and simultaneously bonded and integrated.

The auxiliary member 2 may be fitted only in the two grooves 9 on the surfaces facing each other, and the remaining two grooves 9 may be left bare without any fitting.

The formwork support material of the embodiment is configured as described above, and as shown in FIG.
The support 12 is pressed against the lower surface of the mold 1, and the nail 12 is driven into the auxiliary material 2 from the upper surface of the mold 11 to fix the nail 11 to the mold 11. Further, the support plate 14 of the support 13 and the nail 15 are used for fixing. After completing such preparations, concrete 18 is poured.

In addition, although the above has described the case where the formwork 11 is supported from the lower surface, when using the formwork 11 vertically to pour concrete, a method of supporting by pressing the side face of the formwork 11 is also used. is there. In addition, the wall portion of the body portion 3 serving as the bottom surface of the groove 9 is bent inward in the illustrated case so as to exert strength in the length direction.

[Effect of device]

As described above, this invention uses the aluminum body 3
The main member 1 having the four corners 4 maintains the required strength, and the auxiliary member 2 made of wood is combined with the main member 1, so that the form 11 and the nail can be nailed together. Further, since it is a combination of aluminum and wood, it is lighter in weight than steel pipes, and since wood is used only in the parts necessary for nailing, the amount of wood used may be small. Therefore, there is an effect that the price is not as high as on the left.
