  For example, in the beam located in the upper part of the partition wall, because the beam protrudes from the wall, the formwork alone cannot withstand the dead weight of the placed concrete, so it is in a situation where it can not go out so-called street, It is necessary to take appropriate load-bearing measures. For this reason, conventionally, as shown in FIG. 7, an appropriate pier D is interposed between the beam form A and the upper part of the wall form C. However, the load of the beam B cannot be fully borne, and it cannot be completely prevented from drooping when concrete is hit. In addition, there is a problem that such piers need to be replaced at different floor heights and cannot be used repeatedly.

  On the other hand, in the conventional technique, there is a technique in which a support member having a structure similar to that indicated by reference numeral S in FIG. However, the support member needs to be large with a length from the floor to the beam bottom. Inevitably, the weight also increased, and it was not possible to attach and remove one after another by swinging many of them, resulting in a problem that workability was not very good.

  Further, some of the prior materials are described as a support in Japanese Patent Laid-Open No. Hei 5-156809, and others are described as a metal fitting in Japanese Utility Model Laid-Open No. 7-38438. However, when these are used, it is necessary to attach the support support to the mold for the former, and it is necessary to latch the retainer to the mold for the latter. Therefore, these techniques cannot be applied anytime and anywhere.

  The support system for a beam formwork with a wall according to the present invention supports a beam formwork located at the upper part of the wall from below, and is a deformation typified by drooping at a portion protruding from the wall of the walled beam. In this way, a so-called street can be provided at the bottom of a beam such as a walled beam. In this case, it means almost the same as putting out the horizontal, but preventing drooping will also prevent the side of the beam from being dragged, so the finished condition of the bottom of the beam and the surrounding molding surface This leads to a significant improvement.

  The wall beam formwork supporting apparatus according to the present invention includes a main body and a screw rod. The main body is provided so as to be movable up and down by inserting a screw rod into the inside and screwing the main body into the screw. The vertical movement of the screw rod is an expansion / contraction adjusting means that enables the apparatus to be used in places where floor heights are different. For this reason, it is desirable that the main body has a cylindrical shape with a screw rod passing through, and has a female screw portion that is screwed with a male screw portion of the screw rod in place. The female thread portion can be provided on a part or the whole of the main body.

An engaging portion that engages with a wrench or other tool for rotating operation is provided at the lower end protruding further downward. It is desirable that the support plate be rotatable with respect to the screw rod in order to contact and support the beam formwork from below.

  Further, the engaging portion at the lower end of the screw rod is input means for rotationally driving the screw rod. Input can be manual or powered. Such an engaging portion may be convex such as a screw head larger than the diameter of the screw rod, or may be a concave portion smaller than the diameter of the screw rod. By having such an engaging portion, for example, work by a power machine such as an impact wrench can be performed, and workability can be remarkably improved.

  Since the present invention is constructed and operates as described above, the support system for the beam formwork with a wall can be applied anytime and anywhere, and the load of the cast concrete can be reliably ensured. There is an effect that it is possible to easily catch and pass the street at the bottom of the beam. Further, according to the present invention, it is possible to provide a support device for a wall-mounted beam form which is small, light, easy to handle, and does not burden the operator.
