DETAILED DESCRIPTION OF THE INVENTION

[0001]

[Object of the invention]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an architectural member used at the time of floor construction in a building, and more particularly to an anchor bolt installation structure installed on a deck plate.

[0002]

BACKGROUND OF THE INVENTION In a steel building, when constructing a floor above a floor, a deck plate having an uneven shape is first laid on a steel beam so as to block a space between the floor and the floor. Conventionally, a lower end of a deck anchor bolt is welded at a predetermined position in the above-mentioned manner and is installed in a vertically raised state. The deck anchor bolt has a dimension sufficiently projecting from the upper surface of the mortar after the mortar is cast on the deck plate, and serves to fix the base by the projecting portion.

A conventional installation mode of this deck anchor bolt will be described with reference to the drawings.
Can be roughly set on the deck plate 4 laid on the steel beam F, as shown in FIG. 8 , when it is installed on the convex surface 4A of the deck plate 4, when it is installed on the concave surface 4B, It may be installed in the unit 4C. Therefore, since the heights at which the deck anchor bolts 2 'are installed are different, it is necessary to make the height of the deck anchor bolts 2' at the time of installation equal. Therefore, conventionally, for example, measures such as preparing deck anchor bolts 2'a, 2'b, and 2'c having three different lengths as shown in FIG. 12 in advance are taken. However, when the deck anchor bolt 2 'is installed on the slope 4C, the height of the deck anchor bolt 2' for the slope 4C is prepared in advance because the height varies steplessly at the inclined position. Even so, after all, it was necessary to trim the upper end and make the height equal to that of the other deck anchor bolts 2 '.

[0004] Even if the installation height of the deck anchor bolts 2 'can be made substantially constant by taking the above measures, the work of installing the deck anchor bolts 2' on the deck plate 4 is very troublesome. It was troublesome. Such a problem is caused by the convex portion 4A of the deck plate 4.
When it is installed on the inclined surface 4C, or when it is installed on the concave surface 4B, it is noticeable when it is installed on the slope 4C.
That is, the deck anchor bolt 2 'for the slope 4C
The welding of c was spot welding, and such a welding was difficult to perform because the width of the concave portion 4B was narrow. In addition, since the deck anchor bolt 2 'must be welded in a vertically raised state, it is very difficult for even a skilled worker to install the deck anchor bolt 2' on the slope 4C. Furthermore, since the number of joints is small, there is a concern in terms of strength, such as the deck anchor bolt 2'c being tilted during mortar casting.
In addition, due to the difficulty in performing the welding work as described above, there has been a failure that even an experienced worker may make a hole in the deck plate 4 during welding. Further, it is difficult to mark the installation position of the deck anchor bolt 2'c on the slope 4C, and the mark becomes unclear. As a result, the deck anchor bolt 2'c is displaced from the design site. There was also a problem of being provided.

[0005]

[Technical matters attempted to be developed] The present invention has been made in view of such a background, and a new deck anchor bolt installation that can easily and accurately install a deck anchor bolt on a deck plate. This is an attempt to develop components.

[0006]

According to a second aspect of the present invention, in addition to the above requirements, the bolt flange may further comprise:
It is a rectangular flat member, and its vertical length is next to the deck plate.
Having at least a length exceeding the length between the mating convex portions,
The horizontal length is set shorter than the length between the adjacent convex portions
It is characterized by having been done .

According to a third aspect of the present invention, in addition to the above requirements, the installation body may be a single flat anchor bolt.
It is formed by bending both ends of a plate-shaped member.
It is characterized by the following. The present invention aims to achieve the above object.

[0009]

According to the deck anchor bolt installation member of the first aspect, the deck anchor bolt and the deck anchor bolt are held at a constant height and in a state where the deck anchor bolt is kept at a constant height in a desired horizontal direction. Since it has the installation body provided with the setting position changing means for changing the setting position, a difficult operation such as welding to the slope of the deck plate is eliminated. In addition, there is no need to cut the upper ends of the deck anchor bolts and make the heights uniform, which has been conventionally performed. Furthermore, since the deck anchor bolt installation member of the present invention is installed at a rough position, and then the installation position of the deck anchor bolt is set using the set position changing means, for example, it is necessary to have no experience of installing the deck anchor bolt. Even those skilled in the art can easily and quickly and very accurately install the deck anchor bolts by positioning them vertically with respect to the deck plate.

Further, since the set position changing means is a long guide hole opened in the longitudinal direction of the installation body, horizontal movement is easy. Further, since the structure is simple, the production cost is not required, and the mortar flows well into the lower surface of the installation body from the opening of the guide long hole where the deck anchor bolt is not located.

Further, since the installation body has the legs, the above-mentioned effect is achieved, and it is not necessary to provide a spacer or the like when installing the deck anchor bolt installation member.
