The column 3 is further provided with joint pieces 4 for fixing the end beam 1 and cross-beam 2 to facilitate the connection to the beams 1, 2.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a structure of a floor frame used in a rooftop balcony or the like.

[0002]

2. Description of the Related Art Conventionally, in a floor frame used for a rooftop balcony or the like, either a girder beam and a girder beam are directly joined or a connecting plate is interposed between the girder beams and girder beams. (For example, the actual exploitation 57-18
7909).

[0003]

Among the above-mentioned conventional floor frames, in the case of the type in which the girder beam and the girder beam are directly joined,
Even if there is a slight dimensional error in the beam, there is a drawback that it is likely to cause an error in the entire floor frame. In the case of the type in which the gable beam and the girder beam are joined by interposing a connecting plate therebetween, there is a problem that positioning with the lower floor is not easy and another positioning portion is required.

Therefore, according to the present invention, when a long girder beam and a girder beam are joined, even if there is a dimensional error in the beam, they can be joined easily and accurately so as not to cause an error in the entire floor frame. , And when supporting the floor frame on the lower floor,
It is an object to provide a structure of a floor frame that can be easily and accurately positioned.

[0005]

According to the present invention, in order to solve the above problems, a column having a height slightly higher than the height of the beam is provided at a corner where the gable beam and the girder beam are joined at a right angle. The floor frame was constructed by joining the ends of the gable beam and girder beam to this column. In addition, a positioning concavo-convex portion that fits with each other is provided in the center of the lower end surface of this pillar and in the center of the upper end surface of the pillar on the lower floor on which this pillar is placed to facilitate positioning with the lower floor. A joint piece for fixing the beam and girder beam was provided to facilitate the connection with the beam.

[0006]

In the floor frame of the present invention, the short column is interposed between the gable beam and the girder beam, so that they can be joined accurately and easily. Further, when the floor frame is supported on the lower floor, the positioning concave-convex portions are fitted to each other, whereby the positioning can be performed easily and accurately.
When connecting the gable beam and the girder beam to the joint piece attached to the pillar, the dimensional error between the gable beam and the girder beam can be absorbed here, and the gable beam and the girder beam can be joined more accurately and easily. .

[0007]

An embodiment of the present invention will be described with reference to the drawings. FIG. 1 is a perspective view of a floor frame according to the present invention.

In the figure, gable beams 1 are joined at right angles to each other.
And the girder 2 form a floor frame of the balcony. At the corner where gable beam 1 and girder beam 2 join at a right angle,
A pillar 3 having a low height is provided. Therefore, the gable beam 1 and the girder beam 2 are joined to each other at right angles through the pillar 3.
The pillar 3 has a height approximately equal to that of the beam, that is, a height slightly higher than the height of the gable beam 1 and the girder beam 2. A pair of parallel joint pieces 4 are provided. The end portions of the girder beam 1 and the girder beam 2 are respectively joined to the surfaces of the pillar 3 at right angles and connected to the joint piece 4.

A positioning recess 5 is formed in the center of the lower end surface of the pillar 3. On the other hand, in the center of the upper end surface of the pillar 6 on the lower floor on which the pillar 3 is placed, a convex portion 7 for positioning that fits into the concave portion 5 of the pillar 3 is formed. 8 is a beam on the lower floor.

In the floor frame of this embodiment, however, the beams 1 and 2 can be joined accurately and easily by interposing the short column 3 between the girder beam 1 and the girder beam 2. Further, when the floor frame is supported on the lower floor, by fitting the positioning convex portion of the pillar on the lower floor into the concave portion of the pillar 3, the positioning can be easily and accurately performed. Since the gable beam 1 and the girder beam 2 are connected to the joint piece 4 attached to the pillar 3, the dimensional error between the gable beam 1 and the girder beam 2 is absorbed here, and the gable beam 1 and the girder beam 2 are joined accurately and easily. be able to.

As a matter of course, the present invention is not limited to the above embodiments, and various design changes and the like made within the scope of the present invention are also included in the scope of the present invention. . For example, this floor frame can be applied not only to balconies, but also the positioning concave and convex portions 5 and 7 on the columns 3 and 6 are optional, and which side is provided on which side is free. is there.

[0012]

As described above, in the present invention, the column 3 having a height slightly higher than the height of the beams 1 and 2 is provided at the corner where the gable beam 1 and the girder beam 2 are joined at a right angle. , This pillar 3
Since the floor frame is configured so that the end portions of the gable girder 1 and the girder beam 2 are joined to each other, the short pillar 3 is interposed between the gable girder 1 and the girder beam 2 so that they can be joined accurately and easily. can do.

Further, since the positioning concave and convex portions 5 and 7 which are fitted to each other are provided in the center of the lower end surface of the pillar 3 and the center of the upper end surface of the pillar 6 on the lower floor on which the pillar 3 is placed, the floor frame of the lower floor is installed. In the case of supporting it on the upper side, the positioning concave-convex portions 5 and 7 are fitted to each other, whereby the positioning with the lower floor can be performed easily and accurately. Further, since the pillar 3 is provided with the joint piece 4 for fixing the gable beam 1 and the girder beam 2,
The pillar 3 and the beams 1 and 2 can be easily connected, and the dimensional error of the beams 1 and 2 can be absorbed here, so that the gable beam 1 and the girder beam 2 can be accurately and easily joined.
