Abstract

PURPOSE:To standardize the work in site by fitting anchor bolts and drawing resistance metal fittings on an an-anchor plate. CONSTITUTION:On an anchor plate main-body 11 made of a square steel plate, anchor bolts 21 with four heads 21a are fitted, to compose an anchor plate 10. After that, through the side edge central sections of the anchor plate main- toy 11, nail holes 11a are bored. When the anchor plate 10 is embedded in a wall, then in a form for forming the wall, by nails with the use of the nail holes 11a bored through the side edges of the anchor plate main-body 11, the anchor plate 10 is temporarily held at a specified place. Besides, in a state that the heads 21a of the anchor bolts 21 are entwined with the reinforcements of the wall, the form is filled up with concrete. Besides, the concrete is solidified and after that, by removing the form therefrom, the anchor plate 10 is embedded to be fixed in the wall in a state that the surface of the anchor plate main-body 11 is exposed on the wall surface.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an anchor plate used for fixing a relatively light and small structure to a floor, a wall or the like.

[0002]

2. Description of the Related Art For example, in the case of taking an anchor on a floor, a method of embedding an anchor bolt in a concrete foundation, solidifying the anchor bolt, and attaching a framed pedestal metal member to the anchor bolt is adopted.

When an anchor is attached to a wall, usually,
After reinforced concrete has been solidified and solidified, drill holes are made where necessary, bolts are inserted there, and mortar is filled in and fixed. The member to be fixed to the bolt is attached by welding or the like.

[0004]

As described above, the conventional method is large-scale and the construction is troublesome. An object of the present invention is to provide a small and simple anchor plate.

[0005]

The anchor plate of the present invention comprises an anchor plate body and anchor bolts and pull-out resistance fittings attached thereto.

[0006]

[Operation] An anchor bolt is attached to the anchor plate body, which is small and easy to handle.

[0007]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to FIG.

The anchor plate 10 is constructed by attaching an anchor bolt 21 having four heads 21a to an anchor plate body 11 made of a rectangular steel plate. A nail hole 11 a is formed at the center of the side edge of the anchor plate body 11.

The anchor plate 10 is installed in the factory by attaching the anchor bolts 21 to the anchor plate body 11.
Make it in advance. FIG. 2 shows a method of embedding the anchor plate 10 when embedding it in a wall. (A) Using the nail hole 11a formed in the side edge of the anchor plate body 11 in the mold 15 for forming the wall, the nail 16 is used to move the anchor plate 10 to a predetermined place based on the design drawing. Temporarily stop. Then, the head 21a of the anchor bolt is entangled with the reinforcing bar 17 of the wall. In this state, the mold 15 is filled with concrete. (B) After the concrete is solidified, the mold 15 is removed, so that the anchor plate 10 is embedded and fixed in the wall with the surface of the anchor plate body 11 exposed on the wall surface.

Further, FIG. 3 shows a state when it is fixed to the floor. In this example, the anchor plate body 11
A bolt hole 11b for fixing the structure is formed therein. The structure can be fixed by using the bolt holes 11b.

Further, as described above, the anchor plate body 1
When the anchor plate 10 in which the bolt hole 11b is formed in 1 is used by embedding it in the wall, the bolt hole may be used to temporarily fix the frame 15 from the outside of the frame 15. Then, after removing the form, the bolt holes can be used for fixing the structure.

In the above example, the anchor plate body 1
Although 1 is made of a quadrangular steel plate, the shape of the anchor plate body 11 is not limited to a quadrangular shape, and may be, for example, a rectangular shape, a triangular shape, or a round shape depending on the shape of the structure to be fixed. Also, the material of the anchor plate body 11 is
Not only a steel plate, but also a forged product or a cast product may be used.

Further, the anchor plate body is not limited to a flat plate-shaped one, and may be an anchor plate body 12 having projections 12a formed thereon, as shown in FIG. 4, corresponding to the shape of the lower part of the structure to be fixed. Good. Further, as shown in FIG. 5, for example, the anchor plate body 13 may be formed with a rectangular recess 13a for a prism. In addition,
The shape of the recess 13a may be a round shape for a round pillar, and may be an appropriate shape corresponding to the shape of the structure to be fixed. The anchor bolt 21 may be attached to the anchor plate body 11 by welding or screwing.

Further, the shape of the anchor bolt 21 is not limited to the above-mentioned headed bolt, but may be a rib bar to increase pullout resistance, or the end portion may be bent in a U shape. In the case where the end portion is bent in a U shape, the pullout resistance can be further increased by locking the bent portion to the bar arrangement.

As a measure for increasing the pullout resistance, a pair of headed anchor bolts 21 may be passed through an angle member 22 and fixed to the anchor plate body 11 as shown in FIG. Instead of this angle member, a round or square washer may be attached to each anchor bolt 21 to design the pullout resistance to an arbitrary size.

[0016]

As described above, the anchor plate of the present invention is small in size and easy to handle. Then, by manufacturing the factory in advance, it is possible to manufacture the anchor plate whose quality is controlled according to the schedule. This allows
Can standardize on-site construction. In this way, significant cost savings are possible.
