Abstract

PURPOSE:To secure required and sufficient tensile and suppressing strength by inserting a bar into a cylinder having a cutout at its one end, pressurizing the cylinder at its side of a leading end from back radiation directions, forming a projection on an outer periphery of the bar, and fixing the cylinder to an outer periphery of an insertion portion of the bar. CONSTITUTION:A cylinder 1 having a cutout 1a at its one end and a bar 2 are provided, while the bar 2 is inserted into the cylinder from the other end for preparing an insertion portion 2a. Pressure is applied to the cylinder 1 in a longitudinal and perpendicular direction of the bar 2, and in the back radiation direction on the side of the other end of the cylinder 1, from plural directions P. An outer periphery on the side of a leading end of the insertion portion 2a of the bar 2 is substantially formed as a projection 2b. The cylinder 1 is fixed to the outer periphery of the insertion portion 2a of the bar 2 by pressurizing. The thus prepared cylinder 1 of an anchor bolt is reduced in its diameter by pressurizing from the longitudinal and perpendicular directions of the bar 2, and from the back radiation directions P bringing about such a state that the leading end of the bar 2 is projected in an outer peripheral direction to form the projection 2b. It is thus possible to prevent the bar 2 from escaping from the cylinder 1 even they are pulled in the opposite directions.

Description

Detailed Description of the Invention

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an anchor bolt manufacturing method, an anchor bolt, and an anchor bolt cylinder. That is, the present invention relates to an anchor bolt in which a cylinder and a rod of an anchor bolt having a cylinder having a vertically long cutout portion at one end are prevented from falling off under any external pressure or restraint force.

The rod referred to in the present invention includes not only a columnar rod, which is commonly called, but also a deformed rod having a streak protrusion on its outer periphery as shown in the right end of FIG. 29, and its shape is not limited. or,
Anchor bolts are iron building materials consisting of wedges, tubes and rods that are embedded in the concrete of both in order to strengthen the connection strength between the concrete foundation surface and the superstructure at the construction site.

[0003]

2. Description of the Related Art Conventional anchor bolts are shown in FIGS.
As shown in FIG. 1, a cylinder having a vertically long notch at one end was crimped to one end of the deformed bar. Therefore, pressure is applied from the outer circumference of the cylinder (Fig. 2).
6, FIG. 27, FIG. 31) and pressures P, P1 pass through the other end of the cylinder as shown in FIG.
It is transmitted from part 1 in the P2 direction, and part of it is projected into part N2.

As a modification of the above application, Japanese Patent Application No. 3-
There was 264242. This feature is that the cylinder 1 and the deformed bar 2
In order to increase the crimping force, the deformed rod 2 is heated at a high temperature and then inserted into the cylinder 1, and the crimping force is improved by pressing and crimping from the outer periphery of the cylinder 1 toward the center of the deformed rod 2 in the reverse radial direction. I was letting it.
Since the crimping force was improved in this way, it was thought that sufficient crimping force could be obtained only by pressing the arbitrary positions of the cylinder 1 and the insertion portion 2a of the deformed rod 2. This application (Japanese Patent Application No. 3-
No. 264242) is accompanied by an example according to FIGS. 33 to 35 and given a tentative explanation, but the idea of “protruding portion (2b, 3a to 3g)” in the present application described later is completely described. However, it was thought that sufficient press-fitting force could be obtained only by applying strong pressure, and the deformed bar 2 would not fall out of the cylinder 1.

In any case, in the above-mentioned conventional example, the deformed rod 2 is inserted into the cylinder 1, and pressure is applied from the outside of the cylinder 1 to press the insertion portion 2a of the deformed rod 2 with the cylinder 1 so as to closely contact the two. Let
It was something that did not fall out.

DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described in detail with reference to the embodiments shown in the drawings. An embodiment will be described with reference to FIGS. It is composed of a cylinder 1 having a notch 1a at one end and a rod 2. Insert the rod 2 from the other end of the cylinder 1 to a predetermined center position and insert the insertion portion 2a.
And The outer periphery of the position (or the tip) of the rod 2 near the tip (or tip) of the rod 2 is substantially pressed by pressing the rod 2 toward the other end of the rod 2 from one or more directions P in the direction perpendicular to the longitudinal direction of the rod 2 from the reverse radial direction. Formed as a projecting protrusion 2b. When the pressure is applied in this way, the cylinder 1 adheres to the outer periphery of the insertion portion 2a of the rod 2. The anchor bolt manufactured by the above method is the anchor bolt manufactured by the manufacturing method.

The cylinder 1 of the anchor bolt manufactured by the above-described method is made perpendicular to the longitudinal direction of the rod 2 and is pressed from the reverse radial direction P to be reduced in diameter, and the tip of the rod 2 is projected in the outer peripheral direction. Since the protrusion 2b is formed, it cannot be pulled out or pulled out by pulling the cylinder 1 and the rod 2 in opposite directions. Further, even if the cylinder 1 is fixed and the rod 2 is bent three times again to exert a restraining force, since the protrusion 2b exists, even if the cylinder 1 or the rod 2 is deformed by external pressure, it cannot be easily pulled out.

Different embodiments of the present invention shown in FIGS. 4 to 7 will be described. In the following description of the present embodiment, the same components as those of the above-described embodiment of the present invention will be designated by the same reference numerals and will not be described. A description will be given based on FIGS. 4 to 7. Mainly different from the embodiment of the present invention,
That is, the recess 1b is formed in the center of the inner surface of the cylinder 1. Since this recess 1b is formed, it is perpendicular to the longitudinal direction of the rod 2 and the direction closer to the other end of the cylinder 1 than the opposite radial direction is one or more directions P.
When pressure is applied from the pressure P1, the pressure P1 is transmitted to the other end of the cylinder 1 and the other end of the cylinder 1 is reduced in diameter to be transmitted as pressure P2 inside the rod 1, and part of the pressure P2 is pressure P3, which is a recess 1b on the inner surface of the cylinder 1. Transmitted in the direction. Pressure P1, P2, P transmitted in this way
3, the pressure corresponding to the N1 portion of the rod 2 is pressure P1, P2, P3.
The rod 3 disperses and moves in the direction, and the protruding portion 3 is formed in the protruding portion N2 in the linear direction of the rod 2 and the recessed portion 1b of the cylinder 1.

That is, the recess 1b is prepared as an escape area for a portion corresponding to the N1 portion pushed out by the pressure P1, so that the protrusion 3a can be easily and surely formed. Since the protruding portion 3a is larger than the inner diameter of the other end of the cylinder 1, the tensile strength and the suppression strength are higher than those in the above-described examples. The shape of the recess 1b may be one or more recesses, or may be a groove-like recess, and the position where the recess 1b is formed is the insertion portion 2a except the other end of the cylinder 1. It may be anywhere as long as it is included.

Description will be made with reference to FIGS. 8 and 9. The main difference from the embodiment of the present invention is that the pressure P is applied so that the protrusion 3a becomes a conical protrusion 3b. At this time, the other end of the cylinder 1 may be formed in a truncated cone shape, and the rod 2 may be inserted into the truncated cone cylinder 1c at the other end to apply pressure from the reverse radial direction P.

Description will be made with reference to FIGS. 10 and 11. The main difference from the embodiment of the present invention is that a protrusion 1d is formed on the inner surface of the other end of the cylinder 1. The protrusion 1 is formed on the inner surface of the other end.
When the rod 2 is inserted into the cylinder 1 in which d is formed and pressure is applied from the reverse radial direction P, the outer peripheral portion 3c of the tip of the rod 2 is substantially the protruding portion 2b,
The same effect as 3a is brought about.

Description will be made with reference to FIGS. The main difference from the embodiment of the present invention is that the rod 2 is inserted from the other end of the cylinder 1 having the cutout portion 1a to form the insertion portion 2a, and from the outer circumference of the cylinder 1 from the reverse radial direction P perpendicular to the longitudinal direction of the rod 2. That is, a predetermined position (between FF in the figure) of the cylinder 1 is pressurized (in the figure, pressure is applied only from above). When the pressure is applied in this manner, the GG end surface can be represented as shown in FIG. 13, and the rods 2 in FIG. 13 are dispersed and shown in FIG. That is, the protrusion 3e protrudes in a direction perpendicular to the pressurizing direction and perpendicular to the longitudinal direction of the rod 2, and the tip of the rod 2 substantially remains as the protrusion 3d.

Since the method of manufacturing the anchor bolt and the anchor bolt manufactured in this way are as shown in FIG.
The other end and the rod 2 are fixed and cannot be easily pulled out. Therefore, since there are both the rod 2 tip 3d and the protrusion 3e, that is, the shapes of the GG end face and the rod 2 tip (the rod 2 tip is circular) between FF in FIG. For example, cylinder 1 and stick 2
Even if insufficient insertion of the insertion portion 2a of the cylinder occurs,
I can't pull it out.

Description will be made with reference to FIGS. The main difference from the embodiment of the present invention is that it is applied in the vertical direction on the drawing, that is, from the outer peripheral direction of the cylinder 1 toward the center of the rod 2 in two opposite directions on a straight line perpendicular to the longitudinal direction of the rod 2. That is, the pressure is applied (in FIGS. 16 to 18, the pressure is applied from the upper and lower two directions in the drawings). Since the pressure is applied as described above, the projecting portion 3f projects at right angles to the pressing direction in the direction perpendicular to the longitudinal direction of the rod 2,
Similar to the above-mentioned embodiment, by the tip outer peripheral portion 3d and the protruding portion 3f, the same operational effect as the above-mentioned embodiment can be obtained.

Description will be made with reference to FIGS. The main difference from the embodiment of the present invention is that the rod 2 inserted in the tube 1
The embodiment of (0030) is applied at two points between FF of the insertion portion 2a. That is, M in FIGS.
-On the M end face and the KK end face, from the outer peripheral direction of the cylinder 1 toward the center of the rod 2, two opposite 2 on a straight line perpendicular to the longitudinal direction of the rod 2
That is, pressure was applied from each direction.

Since the pressure is applied from each of the two directions as described above, the protrusion 3f is formed on the MM end face and the protrusion 3 is formed on the KK end face.
g protrudes, and in combination with 3d at the tip of the rod 2, the rod 2 is prevented from coming off and coming off from the cylinder 1 in a double and triple manner. 90 at right angles
FIG. 21 is a view rotated by 90 °, and FIGS. 21 and 22 are also views rotated by 90 ° in the direction perpendicular to the longitudinal direction of the rod 2.

Since the anchor bolt is constructed as described above, the rod 2 cannot be pulled out from the cylinder 1 regardless of the fixing force or the adhesion force (even if the fixing is insufficient).
The accident caused by the stick 2 separating from the cylinder 1 and falling off has disappeared.

The pressing direction in each of the above-mentioned embodiments is not limited to the direction shown and described, and the protruding portion 2 is formed on the outer circumference of the rod 2.
b, 3a to 3g can be formed in any direction, and the positions and shapes of the protruding portions 2b, 3a to 3g are once pressed and fixed so that the cylinder 1 and the rod 2 are pulled from both ends. Also, any position and any shape may be used as long as the position and the shape are such that they do not fall off or fall out even if the force is applied. Further, in the present invention, the protruding portions 2b, 3 are provided at one end of the rod 2.
a to 3g is formed, one end of the rod 2 is inserted into the other end of the cylinder 1, and the rod 2 is enclosed by the inner surface of the cylinder 1 having the same shape as the surface of one end of the rod 2 and one end of the cylinder 1 and the rod 2. If they are fixed, it does not matter what shape they are and how they are fixed.

Description will be made with reference to FIG. The main difference from the embodiment of the present invention is that a step 1e is formed at a predetermined position on the inner surface of the cylinder 1 having a notch 1a at one end.
The projection 1f may be used (FIG. 25), and any shape may be used as long as the rod 2 cannot be inserted further into the back]. One end of the rod 2 is inserted from the other end of the cylinder 1 and brought into contact with the step portion 1e. With the rod 2 in contact with the step portion 1e of the cylinder 1, the outer peripheral direction of the cylinder 1, that is, the reverse radial direction P
The pressure is applied from the direction perpendicular to the longitudinal direction of the rod 2. With the above-described structure, an anchor bolt having an insertion portion 2a of a constant length can be manufactured at all times, and an inexpensive product with stable quality can be obtained.

[0036]

According to the anchor bolt of the present invention,
The effects listed below can be obtained. 1) Since the protruding part is formed on the tip and the tip of the rod, and the other end of the cylinder is attached to the insertion part of the rod, the rod will drop from the cylinder even if the cylinder and the rod are not completely and firmly fixed. An anchor bolt having a high tensile strength and a strong suppressing strength was obtained without separation. 2) Since the recess is formed in the center of the inner surface of the cylinder, the recess serves as an escape area for the pressurized member, and the protrusion can be formed easily and reliably by applying a relatively low pressure. 3) Since a substantial protrusion is formed regardless of the protrusion,
It has become possible to easily and reliably form the protrusion with a relatively low pressure.

4) Since pressure is applied from the outer peripheral direction of the cylinder to the opposite radial direction from the direction perpendicular to the longitudinal direction of the rod to form a protruding portion on the rod, the cylinder and the rod do not come off even if the fixing force is insufficient. , There was no accident due to the stick falling off the cylinder. As a result, defective products due to insufficient adhesion disappeared, and the manufacturing cost of anchor bolts was reduced. 5) At multiple positions, pressure was applied from the outer peripheral direction of the cylinder toward the center of the deformed bar in the direction perpendicular to the longitudinal direction of the deformed bar, and a bulge portion was formed on the deformed bar. Disappeared.

6) Since the step is formed at a predetermined position on the inner surface of the cylinder, anyone can make the insertion length of the deformed rod inserted into the cylinder constant,
Anchor bolts of stable quality can be obtained, and since the insertion length is constant regardless of who does it, co-stable and reliable anchor bolts can be made by no one skilled in the art, thus reducing the manufacturing cost of the anchor bolts.

7) As a result, it was possible to obtain an anchor bolt which is safe at low cost and does not drop the rod from the cylinder, that is, the tensile strength and the suppressing strength are both strong.
