Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention, when building a steel frame of a building such as a high-rise building, constitutes a joint portion of a column column, a support column or a beam made of H steel, etc., and is a steel frame supporting joint called a dice or a joint for supporting and connecting the steel frame. It is about ingredients.

[0002]

[Prior art]

 Conventionally, this type of steel frame support fitting is made by bending an iron plate into a U-shape and welding a joint part by applying a supplementary plate to one side, or four side plates having a square shape, a trapezoidal shape, etc. It has been constructed by welding the joints according to the required shape to form the column main body, and welding and joining the diaphragms to be the connecting plates to both ends of the column main body.

[0003]

[Problems to be solved by the device]

 However, the joint portion of the steel frame that constitutes the skeleton of the building is, of course, required to have sufficient strength for supporting the construction and complete welded joint.

However, if the steel-framed support joint itself is formed by welding, there remains concern about whether or not the welded portion is completely welded, and a flaw inspection of the welded portion becomes necessary. .

[0005] The flaw detection inspection of the welded portion has a mechanism that requires a UT inspection (ultrasonic flaw detection inspection) by an ultrasonic liquid by a third party organization after the self-inspection, and in addition to the inspection cost, the inspection is performed. It takes time and often affects the progress of the original building construction work.

Further, when the diaphragm is welded and joined to the column, there is a problem that welding distortion occurs in the diaphragm, and it takes much time and cost to correct it.

[0007]

[Means for Solving the Problems] The present invention addresses the above-mentioned problems, and a column forming a main body and a diaphragm forming a connecting portion are integrally formed by form molding. It has been resolved.

[0008]

[Action]

 Forming such as casting, forging, or die casting can be used, so that materials such as cast steel, castings, and resins can be selected according to the purpose of use, and the shape can be freely configured according to the actual conditions of use.

Since it is integrally formed, the existence of a welded joint is eliminated and the need for UT inspection is eliminated, so the time loss required for inspection is eliminated, and there is no problem of rework after UT inspection, and a stable production schedule is possible. It was set up and it was possible to carry out the process work reliably.

Further, if the radius portions of the diaphragm and the column are configured to be large, it is possible to avoid concentration of stress applied to the diaphragm.

【Example】

 Embodiments of the present invention will be described below with reference to the drawings. Reference numeral 1 is a column which constitutes the main body, and diaphragms 2 and 2 are integrally formed at both ends together with a lower reinforcing rounded portion 3. In addition, a hollow portion 6 is formed in the column 1 for weight adjustment. Reference numeral 7 is a hole for molding the hollow portion 6 of the main body.

The end faces of the column pillars A1 and A2 are welded to the diaphragms 2 and 2, respectively, so that a vertical joint is formed.

In the horizontal joint, the column 5 is provided with a joint 5 for receiving the transverse beam in each required direction, and the transverse beam is superposed on the joint 5 to form a bolted joint by the bolt holes 4, 4.

The joints 5 provided in the column 1 are provided in any direction such as one direction, two directions, and three directions as needed, and the angle with respect to the column 1 is not limited to horizontal, and can be set to the front downward and the front upward. The angle can be set.

Further, the shape is also set to a free shape such that the width of the cross beam is made to correspond to the width of the joint by tapering or stepping.

The joints 5, 5, ... Receiving the transverse beams have conventionally been welded and joined on site, but if standardization is possible, these joints 5, 5 ,. Forming by molding is more effective because it eliminates the dangerous and troublesome work of welding and joining on-site.

.., which are conventionally welded and joined on site, are sandwiched between the diaphragms 2 and 2 as shown in FIG. 4 and joined, and the diaphragms are joined as shown in FIG. When it was made the same level as the end face of No. 2, it was necessary to prepare the weld end face with a scrap processing machine etc., but if it is integrally formed, no consideration is necessary.

Further, if necessary, a deformed steel frame support joint tool as shown in FIGS. 2 and 3 is integrally formed by molding.

[0019]

[Effect of device]

 Since the present invention is configured as described above, it eliminates the time loss required for UT inspection and rework after inspection, enables stable production schedule of steel frame support fittings, and greatly improves the efficiency of steel frame installation work. It was made.

Further, there is an effect that a product having a uniform and uniform precision by integral molding can be molded into a shape suitable for the actual situation and supplied.

[Correction content]

The joints 5, 5, ..., Which are conventionally welded and joined in a factory and on-site, are sandwiched between the diaphragms 2 and 2 as shown in FIG. 4 and joined, and as shown in FIG. When the level of the end face of the diaphragm 2 is set to the same level, it was necessary to maintain the weld end face by a scalloping machine or the like, but if it is integrally formed, there is no need to consider it.

Further, since the welding work is eliminated, it is possible to save labor and increase production. If casting is used, the quality is uniform and the product quality can be maintained. Furthermore, there is an effect that a product having a uniform and uniform accuracy can be molded into a shape suitable for the actual situation and supplied by integral molding.
