DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an improvement of a self-supporting construction method of a foundation beam for allowing a plurality of foundation beams constituting a foundation part to stand independently before the fixing work.

[0002]

2. Description of the Related Art In order to construct a building in a stable state, a foundation must first be constructed stably and accurately on the ground. As an example of the construction of such a foundation, an excavation hole is formed at a predetermined location in the installation area of the building, an independent foundation is constructed for each of the excavation holes, and a foundation beam is hung on the independent foundation, and the entire foundation is The constituent independent basic forms are used.

In such a form of the independent foundation, work is performed in which the foundation beams are installed between the independent foundations in a direction orthogonal to each other or in parallel on a straight line and fixedly connected thereto. A jig is used to make the foundation beams self-supporting so that they do not fall down.

FIG. 4 is an explanatory view showing an example of a conventional self-supporting method for foundation beams. As shown in the drawing, the foundation beams 110a and 110b are installed so as to be substantially orthogonal to each other, and they are later fixed by concrete at the orthogonal joints, but they must be left standing until the fixing operation is performed. Must. Therefore, for example, flat plate receiving portions 114 are attached to both ends of a steel pole 112, and one receiving portion 114 is brought into contact with the foundation beam 110, and the other receiving portion 114 is brought into contact with the installation ground side to be installed. Thus, the foundation beam 110 is supported. Such pole-type self-supporting jigs 116 are installed on both side surfaces of the foundation beam 110, respectively, to prevent the installed foundation beam 110 from overturning due to vibration or impact during work.

[0005]

The above-mentioned conventional jig for self-supporting foundation beams needs to be installed at least one on each side of the installed foundation beams, and the foundation beams installed on the entire foundation are required. In order to support it, a very large number of pole-shaped self-supporting jigs 116 are required. Further, the pole-shaped self-supporting jig 116 is made of steel or the like in order to make the strength sufficient, so that the weight is heavy. Therefore, transporting a large number of the self-supporting jigs 116 and performing the installation work requires an extremely large amount of labor, and there is a problem that the efficiency of the foundation installation work is reduced. Also, this kind of jig 116
Since it protrudes into the working area inside and outside the foundation beam 110, it is necessary to perform the work while avoiding this, and this also reduces the work efficiency.

SUMMARY OF THE INVENTION The present invention has been made to solve the above problems, and an object thereof is to maintain a stable self-standing state of a foundation beam arranged between independent foundations by a member having a simple structure. It is an object of the present invention to provide a method of self-supporting foundation beams that can be performed without reducing the work area.

[0007]

In order to achieve the above object, a method for self-supporting a foundation beam according to claim 1 comprises a holding portion fitted to an upper end of a foundation beam to be connected, A straight-line connecting portion that supports a connecting rod parallel to the longitudinal axis of the foundation beam that is linearly connected on the side surface, and a longitudinal axis of the foundation beam that is orthogonally connected on the upper surface of the holding portion. An orthogonal connecting portion that supports the connecting rod in an intersecting state, and a self-standing construction method of a foundation beam using a self-supporting jig including:
The foundation beam is installed linearly or orthogonally, and the holding part of the self-supporting jig is fitted to an upper end portion of the foundation beam installed linearly or orthogonally, and the self-supporting jig is mounted. Then, the connecting rod is supported by straight connecting portions provided on the side surfaces of the self-supporting jig or orthogonal connecting portions provided on the upper surface and fixed via fixing means, and the foundation beam is straight or It is characterized by being connected orthogonally.

According to a second aspect of the present invention, the foundation beam is installed in a straight line, and a wedge is formed in a gap between the connecting rod supported by the straight connecting portion and the foundation beam. The material is driven.

[0009]

According to the self-standing construction method of the foundation beam according to the first aspect, the self-supporting jig is attached to each upper end of the foundation beam to be connected, and the straight connection part or the orthogonal part of the self-standing jig is connected. The connecting rod is supported by the connecting part and is fixed via fixing means. Thereby, the foundation beams support each other. In other words, if any impact is applied to one of the foundation beams and a force is generated in the direction of falling, the other foundation beam joined by the self-supporting jig and the connecting rod supports this, and the foundation beam is securely prevented from overturning can do.

Further, according to the self-standing construction method, the foundation beam can be self-supported by using a self-standing jig and a connecting rod having a relatively simple structure, and labor for installing a heavy jig is reduced. The work area can be reduced because the jig does not protrude significantly outside the foundation beam.

Further, since the self-standing jig is provided with both the straight connecting portion and the orthogonal connecting portion, the connecting rod is supported by the straight connecting portion when the foundation beam is arranged on a straight line. When the foundation beams are arranged orthogonally, the connecting rod can be supported by the orthogonal connecting portion. Therefore, the jig for self-supporting can be used regardless of whether the installation direction of the foundation beam is orthogonal or linear.

Next, according to the independent construction method of the foundation beam according to the second aspect, the wedge member is fitted into the gap between the connection rod and the foundation beam, so that the connection rod is firmly fixed and the foundation beam is securely attached. Can support and become independent.
