Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Field of Application 1] The present invention relates to a supporting and fixing device for a mold frame. More particularly, it relates to support and anchorage devices for concrete wall molds.

[Background of the Invention] In [No. 159-263428 (hereinafter referred to as the earlier invention), the present applicant proposed a truncated conical fixing fitting for fixing the lower part of a single panel assembly in a predetermined position. There is. In other words, the previous invention has a truncated conical metal fitting located between the inner and outer panels of the plastic frame (as shown in Fig. 5).
5) and an inverted truncated conical metal fitting (5C) installed in advance on the lower end face of a slab type frame, as shown in FIG.

All of those gold Rf51 (5C) have female threads (5C).
1), (53) are engraved, and screws (52) are attached to them.
, (53'), the panel assembly itself can be fixed in a predetermined position.

Since these metal fittings (5) and (5C) are formed in the shape of a truncated cone or an inverted truncated cone, they can be easily handled from the solidified concrete and can be used repeatedly.

[Problems to be Solved by the Invention] A truncated conical metal fitting (5) is attached to the lower end of the concrete wall mold as a spacer and fixing member, and a truncated conical metal fitting (5) is attached in advance to the lower end of the slab mold as a spacer and fixing member. Since the installed inverted truncated conical metal fittings (5C) work together, the mold frame is usually sufficiently fixed in place.

However, in construction work that requires a large load or in which it is necessary to fix the shape of the concrete wall with strict precision, the inverted truncated conical metal fittings (5C) are attached to the slab-type frame panel (81) using screws (53°). There are cases where it is insufficient to simply fix the material.

The present invention has been proposed to eliminate such inconveniences, and its main purpose is to provide a supporting and fixing device for concrete wall forms with high constant strength.

[Means for Solving Problem E] The form frame support determining device of the present invention fixes the form of a concrete wall, which is made up of individual inner and outer panels and inner and outer joists, into a truncated cone shape near the lower end of the line. It is configured to be supported and fixed by a metal fitting and a screw, and also supported and fixed by another truncated conical metal fitting and a screw on the lower end surface of the slab type frame, It is characterized in that it is configured so that another truncated conical metal fitting previously installed on the side end surface is supported and fixed to the floorboard of the downstairs floor via a support and a fixing member provided at the lower end of the support.

Further, the truncated conical metal fittings installed in advance on the slab mold frame to support and fix the concrete wall mold are:
It is preferable to support the slab type frame with a support via a panel of the slab type frame, or to fix it with a screw to the flange of a finger member that supports the slab type frame, and to support the flange with a support.

[Function] The truncated conical metal fittings that support and fix the concrete wall mold can be supported by erecting a support from the floor below and placing its tip directly under the back of the mold frame on which the metal fitting is placed. Alternatively, this can be achieved by once tightening the metal fittings with screws to the flanges of the finger members for supporting the slab-type frame, and supporting the seven flanges with the struts in the same manner as described above.

[Embodiment] Fig. 1 is a partially sectional front view showing an embodiment of the support fixing device of the present invention, and Fig. 2 shows a preferred embodiment of the top end portion of the support window 91I device shown in Fig. 1. 1 Main part FIG. 3 is an enlarged cross-sectional view of a main part showing a preferred example of fastening the fixing member at the lower end of the support and fixing device shown in FIG. Figure 5 is a partial cross-sectional front view showing a state in which the fixing member is directly supported and fixed to the joist at the lower end of the concrete wall instead of the above-mentioned supporting and fixing device. FIG. 6 is a cross-sectional view showing an example of a conventional fixing member. FIG. 6 is a cross-sectional view showing an example of a conventional fixing member in which a concrete wall mold is provided with support windows i at both ends of a slab mold frame.

In Fig. 1, the inverted truncated conical metal fitting (5C) shown in Fig. 6 is used as a support and fixing device, and this is attached to a panel (81) of a slab mold frame with a screw (53'). While supporting and fixing the concrete wall mold, the entire mold frame is attached to the slab mold frame panel (8) using the metal fittings (5C).
1) from the back side with a support post (9), and further attach the support support (
9) The lower end of the present invention is supported and fixed on the floor below via the fixing member (5A)! ! Company i (S) is shown. As shown in FIG. 1, the receiving end of the metal fitting (5C) can be simply supported by abutting against the back surface of the panel (81) of the slab type frame via the plate (8), or a second supporting end. As shown in the figure, once screw the inverted truncated conical metal fitting (5C) (53°) to the flange (82a) of finger 0 (82).
), and a hollow support member (91) screwed to the upper end of the support column (9) is brought into contact with the lower surface of the flange (82a) for support.

In either case, as shown in FIG. 3, the branch office (9) is screwed and fitted at its lower supporting and fixing end by a fixing member (5A) embedded in the slab on the floor in advance. The fixing member (5A) has an inverted truncated conical metal fitting (5E) with a plurality of small screw holes (56) formed on the outer edge and a large screw hole (61) in the center, and is a vertically adjustable connecting base (5F) in which small screw holes (57) and (58) are drilled as in IJm, and a male screw that screws into the large screw hole (61) is formed on the curved part. It consists of.

To use those WliRs, first, before assembling the slab type frame, attach the support (9)! l! While standing upright, insert the threaded rod (59) and screw (60) at the tip into the screw holes (58) and (57) of the fixing member (5A), which has been buried in a predetermined position on the floor during the construction. Temporarily screw together, the support member (91) of the support (9) is brought into contact with the flange (82a) of the finger member (82), and the connection base (5F) is fixed to the height of 81. While adjusting the support column (9) up and down, screw it into the screw hole (56) with another screw to fix the support column (9). After laying the slab type frame between the finger members (82), an inverted truncated conical metal fitting (5C) is placed on the slab type frame surface above the support member (91), and the support member (91 ) from the hollow part and tighten the screw (53°) to fix it. If you place a concrete wall mold on top of it,
The load of this type is transferred from the inverted truncated conical metal fitting (5C) to the support member (91), and then to the support (9) and fixed member (5A).
Since it is directly supported and fixed on the floor below, it does not lose its shape.

Of course, instead of placing the inverted truncated cone-shaped metal fitting (5C), it may be fixed in the state shown in Figure 6. In that case, the support determination device (S) can be used repeatedly, and construction works such as high-rise buildings can be carried out. It is also extremely convenient.

In addition, as shown in Fig. 4, the concrete of the slab is poured first, and the fixing member (5A) is placed at a predetermined position on the slab.
! l! The concrete may be fixed by directly tightening the screws (63) to the joists (71) of the mold.

[Effects of the Invention] According to the present invention, the supporting and fixing of the concrete wall mold in the previous invention is performed reliably, thereby improving the quality of construction work. Also, design? 7i It goes without saying that this also applies to heavy construction work.
