DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a support for supporting an inclined structure such as a form of a concrete stair or a precast concrete stair, and a method of installing the inclined structure.

[0002]

2. Description of the Related Art Conventionally, for example, a form of a cast-in-place concrete staircase is installed by obliquely supporting an inclined surface of the form with a plurality of supports from below so as to have a predetermined inclination angle. . On the other hand, the conventional support 30 has a structure having a horizontal base plate 31 at the lower end and a horizontal receiving plate 32 at the upper end, as shown in FIGS.
The structure is supported by a horizontal receiving plate 32.
Therefore, when supporting an inclined surface such as a form of a concrete staircase with a support, if the support is set up vertically, only the edge of the receiving plate hits the inclined surface, and the receiving plate and the inclined surface are in line contact with each other and the axis of the support is The formwork is supported in an offset load state at a position deviated from the above, and it becomes very unstable.

[0003] For this reason, for example, when the formwork 35 of the cast-in-place concrete stairs is installed, the inclined surface 36 is supported by the receiving plate 32 of the support 30 erected vertically, as shown in FIG. It is performed by any of the methods shown in an enlarged manner. That is, a joist 33 composed of approximately 90 × 90 square timber and a square timber of different size of the crosspiece 34 are superposed and arranged at right angles (in the inclined direction and the width direction), and the corners of the square timber are substantially aligned with the axis of the receiving plate. By installing, adjust to become uneven load,
Further, a slip stopper 37 is provided in a space between the inclined surface of the timber and the receiving plate.
Is inserted and fixed with nails. And, since only the support which stands upright is unstable, the support is usually set up obliquely so that the support plate of the support comes into surface contact with the inclined surface of the inclined structure as shown in FIG. Support is provided by a combination of a vertical support 30 and an oblique support 30 '.

[0004]

Therefore, in the conventional method of installing an inclined structure using supports, the supports must be supported by a large number of supports in a combination of a vertical state and an oblique state, and the support by individual supports is required. The work is complicated, inefficient and unstable. In order to adjust the angle of the inclined structure, there is a problem that the work of fixing the inclined surface and the support is unstable, so that the work is dangerous, difficult to perform, requires skill, and takes a long time. .

SUMMARY OF THE INVENTION The present invention has been made in view of the above circumstances, and is intended to stabilize a slope of an inclined structure such as a formwork of a concrete stair or a precast concrete stair only by erecting a support vertically. The support for the inclined structure installation method, which can easily adjust the horizontal and vertical of the inclined structure, can reduce the number of supports, and the installation work is safe, easy and efficient An object of the present invention is to provide an installation method of an inclined structure.

The upper column tube 7 can be appropriately adjusted in the length direction by a known adjusting means 8 such as an adjusting screw.

The receiving plate 3 is fixed to the top of the upper column tube 7. As shown in an enlarged view in FIG. 2, the top of the upper column tube is open, and an inclined structure of the inclined structure is formed in the opening. A support 10 that supports the inclined surface 2 is detachably inserted and attached. The support 10 has an inclined support plate 11 which is engaged in surface contact with the inclined surface 2 of the inclined structure, and in this embodiment, a vertical member 1 for fixing the inclined support plate 11 in an inclined state.
3 and a horizontal plate 12 are formed in a right-angled cross section,
An insertion pipe 14 for being inserted into the top of the support body 4 is fixed to the lower surface of the horizontal plate 12. The inclined support plate 11 of the support 10 is formed so as to have a gradient substantially similar to the inclination angle of the stairs with respect to the axis of the support. Therefore, only by erecting the support vertically, the entire inclined support plate of the support can be brought into surface contact with the inclined surface 2 of the inclined structure to support the inclined structure. Can be stably supported.

The support 10 only needs to have the inclined support plate 11 that satisfies the above conditions, and its shape is not particularly limited. In addition, the material is made of metal in the present embodiment, but is not particularly limited, and is not limited to metal, and may be wood or plastic depending on the application.
