Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

The present invention relates to an anchor bolt,
The present invention relates to a head structure of an insertion member such as a reinforcing bar.

[0002]

2. Description of the Related Art Conventionally, floor members, ceiling surfaces, wall surfaces, and other members (hereinafter, referred to as anchor bolts) are used as insertion bars, such as anchor bolts and reinforcing bars, as differential bars.
Floor. ), And using the fixed anchor bolts and long reinforcing bars or support members to attach mountings such as plates, hooks, and machines to the floor, ceiling, or wall surface, etc. First, it is necessary to rotationally press an anchor bolt into a hole formed in a floor, a ceiling, a wall, or the like. Therefore, after cutting off the tip of the anchor bolt to approximately 45 °, a nut (hereinafter, referred to as a hexagon nut) such as a hexagon nut or a hexagon double nut is screwed to the rear end (head screw shaft portion). A locking hole of a tool (embedding machine) is fitted into the screwed hexagon nut, and the tool is operated to rotationally press-fit the hexagon nut into the chemical filling hole. Then, cure. After curing, the anchor bolt and the reinforcing bar or the support member of the long object are connected.At this time, the hexagon nut of the anchor bolt is unscrewed or cut, and the unscrewed or cut screw shaft has a rear end. Obtain a crimping or welding process and attach the rebar or support member. An attachment or the like is attached or supported using the reinforcing bar or the support member. Therefore, there have been problems such as the necessity of operations such as screwing and unscrewing and cutting of the hexagon nut and the extremely troublesome operation.

[0003] It should be noted that although the content of the prior art is substantially the same as that of the prior art, the invention in which the head of the anchor bolt is improved is disclosed in Japanese Patent Laid-Open Publication
There is an invention of 7-62751. SUMMARY OF THE INVENTION It is an object of the present invention to make the diameters of the screw shafts of the embedded portion and the protruding portion different from each other so as to match the bolt hole diameter of the attachment. Therefore, although the improvement of the head is similar to the present invention, there is no similarity in the configuration.

[0004]

As described above, the configuration in which the hexagon nut is screwed to the rear end of the anchor bolt has a problem that requires labor and labor. In addition, when several hexagonal nuts are bundled when screwing and handling the hexagonal nut, the hexagonal nut becomes a hindrance, and there are problems such as poor binding and bulkiness. In the case where the rear end of the anchor bolt is cut and the reinforcing bar and the supporting member are pressed or welded, in a normal state, there is a problem that the hexagon nut becomes waste material and causes loss of material.

[0005]

According to the first aspect of the present invention, a hexagonal nut is not required, so that the labor and time required for the operation can be reduced, the troublesome operation can be eliminated, the cost can be reduced, or the binding, storage and storage can be facilitated. Furthermore, it aims at resource saving.

In the present invention, a locking portion for locking a tool is provided on the head of the anchor bolt, and the locking portion can be aligned with a locking hole of the tool. ,
A head structure of an insertion member such as an anchor bolt and a reinforcing bar, wherein the anchor bolt is inserted into a floor surface, a ceiling surface, a wall surface, and other members of a building.

Another object of the present invention is to make it possible to easily operate the locking portion by using a conventional tool.

In the present invention, the locking portion has a hexagonal nut shape.
This is a head structure of an insertion member such as an anchor bolt or a reinforcing bar having a nut shape such as a square nut shape or a triangle nut shape.

A third object of the present invention is to easily process a locking portion by using a conventional processing machine and to process a conventional product.

The present invention is directed to a head structure of an insertion member such as an anchor bolt and a reinforcing bar, wherein a locking portion is formed by utilizing plastic deformation by press working and homing.

[0011]

Embodiments of the present invention will be described.
After drilling the base material in the same manner as before, the inside of the hole is cleaned and the anchor bolt is embedded. First, a chemical capsule (cup) is inserted into the hole. About the end of the anchor bolt
Cut one side to 45 °, align the locking part with the locking hole of the tool as it is, break and stir the chemical capsule while rotating and hitting the anchor bolt, gently embed to the specified embedding depth, marking Stop the tool as soon as it reaches the construction surface (when the tip of the anchor bolt reaches the bottom of the hole). Remove the tool without moving the embedded anchor bolt. Then, after the curing time has elapsed, the attachment is engaged in installation, and the attachment is screwed and tightened using a hexagon nut. Then, the attachment is cut off, or the attachment is fixed via pressing, welding, or the like of the engagement. In addition, a reinforcing bar may be welded to the locking portion of the anchor bolt (the locking portion is a welding base material). In the anchor bolt of the present invention, the locking portion inserted into the locking hole of the screw shaft and the tool is configured to have substantially the same diameter or small diameter, so that the binding operation at the time of binding can be performed easily and easily. Or, there is no need to screw on and off the nut at the time of embedding the anchor bolt, and it is simple and useful for improving workability.

[0012]

An embodiment of the present invention will be described below.

1 is an anchor bolt main body, 111 is a screw portion, and 112 is a head. The locking portion 2 is formed on the head 112. The shape of the locking portion 2 is adapted to a locking hole of a tool socket or an adapter (not shown), and is a hexagon nut shape in FIG. 2, a square nut shape in FIG. 3, or a triangle (not shown). Nut shape, polygonal nut shape, etc. As a method of forming the locking portion 2, a method of forming the existing anchor bolt body 1 ′,
It may be a method of forming at the time of manufacturing. Then, for example, in the method of forming on the existing anchor bolt main body 1 ', a configuration in which the engaging portion uses plastic deformation by press working, homing processing, or the like can be considered. Further, as a method of forming at the time of manufacturing, a configuration utilizing a casting process, a configuration utilizing plastic deformation as described above, or the like can be considered. In addition, the locking part 2
Is ideally approximately 1.5 to 2.0 times the height of each nut screwed onto each existing anchor bolt body 1 '.

In the figure, reference numeral 3 denotes a screw, and 4 denotes a projection of the anchor bolt main body 1 or the reinforcing bar 5.

[0015]

According to the first aspect of the present invention, there is provided a head structure of an anchor bolt having a locking portion for locking a tool on a head of the anchor bolt, and aligning the locking portion with a locking hole of the tool. In this configuration, the anchor bolt is inserted into a wall, floor, ceiling, or other member of the building by operating the tool. Therefore, hexagon nuts are not required , reducing the labor and work
It is useful for eliminating work and reducing costs, or for binding, facilitating storage and storage, and further conserving resources.

The head structure of the anchor bolt according to the second aspect of the present invention is configured such that the locking portion has a nut shape such as a hexagonal nut shape, a square nut shape, and a triangular nut shape. Therefore,
There is a feature that the locking portion can be easily operated using a conventional tool.
