DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION In order to connect a ground floor structure to a steel basement, anchor bolts are usually welded to the roof panel of the steel basement. The present invention relates to a steel basement roof panel in which a connection plate is welded instead of directly welding the anchor bolt.

[0002]

2. Description of the Related Art In recent years, in many cases, basements are often provided even in houses. In addition, in order to shorten the construction period and to save labor in construction, this kind of basement is entirely provided with a steel plate for roof and a steel plate, a steel plate for a wall and a steel plate. 2. Description of the Related Art A method of constructing a steel panel formed of a steel sheet for a floor and a mold steel by appropriately connecting on-site with a connecting bolt or the like and assembling the panel by a so-called prefabricated method has been widely implemented.

[0003] Generally, a ground floor structure such as a house is constructed on a steel basement.

In this case, the steel basement and the ground floor structure are
In order to make a strong and reliable connection, anchor bolts are provided vertically toward the outer upper surface of the roof panel of the steel basement, but conventionally, for example, as disclosed in JP-A-5-62186, steel plates constituting the roof panel In this case, the anchor bolt is directly welded to the outer upper surface of the roof panel, or a hole is formed in the roof panel so that the anchor bolt penetrates, and the anchor bolt is directly welded to the steel shape forming the panel through the hole.

[0005] Fig. 4 shows an example of a perspective view of a steel basement, in which anchor bolts are directly welded to steel plates constituting a roof panel of the steel basement. FIG. 5 is a diagram in which an anchor bolt is welded to a steel pattern forming a roof panel.

[0006]

However, the above-described method of attaching the anchor bolt has the following problems. (B) Welding anchor bolts to a flat surface requires skill and is difficult. (B) Therefore, the anchor bolt attached by such a method may lack reliability in strength. (C) In addition, since panels manufactured and assembled in a factory are assembled on site, the panels may be obstructed during transportation or stacking of the panels or during lifting assembly, and may be bent or broken.

The present invention has been made in view of the above problems, and provides a roof panel with a connecting plate for a steel basement, which is highly reliable in terms of strength, has good workability, and is easy to handle.

[0008]

SUMMARY OF THE INVENTION A steel basement is provided.
Connection plate is welded to the steel form of the roof panel
And cut out the steel plate to avoid the connection plate
Weld over the steel plate provided and weld it to the connection plate.
Of steel basements characterized by connecting floor structures
The gist of the invention is that it is a roof panel with a connection plate.

A second aspect of the present invention is to construct a roof panel of a steel basement.
The steel sheet to be formed, contact dissolve the connection plate, pre for the connection
Characterized by connecting a ground floor structure to a floor
Roof panels with connecting plates for basement
To the effect.

[0010]

The operation of the present invention is as follows. (A) Since the connection plate is welded to the steel plate or roof steel for the panel, the anchor plate is directly attached to the steel plate or steel.
Welding is easier than spot welding . (B) Since the welded part is a line weld , the surface of the connection plate
It is resistant to tension, compression, shear and bending acting in and out of plane . (C) Since the anchor bolt does not travel longer than the panel, it does not hinder the panel during transportation, stacking, and lifting assembly, and is less likely to bend or break.

[0011]

BRIEF DESCRIPTION OF THE DRAWINGS FIG. FIG. 1A is a side view of one embodiment of the present invention. (B) is a front view and (c) is a top view. A steel plate 2 provided with a notch 3 is welded to a shape steel 1 constituting a roof panel of a steel basement, and a connection plate 4 is attached to the shape steel 1,
Weld perpendicular to the profile. For example, a wing plate bolt 5 is attached to the connection plate 4 with a bolt / nut 6 to form an anchor bolt. It goes without saying that various methods of attaching the anchor bolt to the connection plate 4 are conceivable and direct welding is also possible. In this case, since the anchor bolt and the welding surface are not perpendicular to the point, welding is easy and the strength is guaranteed.

FIG. 2 is a perspective view of a portion in which the connection plate is welded to the mold steel.

FIG. 3 is a view in which a mold steel 7 serving as a base of a structure directly connected to an upper floor is connected to a connecting plate by bolts. Of course, welding can also be performed.

[0014]

The effects of the present invention are as follows. (A) Since the connection plate is wire-welded to the roof steel plate or steel plate constituting the panel, the anchor plate is directly attached to the steel plate or steel plate.
Welding is easier than spot welding . (B) Since the welded part is a line weld , the surface of the connection plate
It is resistant to tension, compression, shear and bending acting in and out of plane . (C) Since the anchor bolt does not travel longer than the panel, it does not hinder the panel during transportation, stacking, and lifting assembly, and is less likely to bend or break.
