BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an anchor bolt used when constructing a post-installed anchor on a concrete floor surface, a wall surface, a ceiling surface or the like, and a construction method thereof.
[0002]
2. Description of the Related Art Conventionally, post-installed anchors are classified into adhesive type anchors and main body driven anchors, each of which has many types. FIG. 10: shows the construction example of the post-construction anchor of the conventional adhesive type anchor. As shown in FIG. 10 (1), the concrete skeleton 9 is perforated with holes for embedding the capsule 15 in which the adhesive is enclosed, and as shown in FIG.
After cleaning the perforations with, insert the capsule 15 as shown in FIG. 10 (3), then insert the anchor bolt 18 with stirring as shown in FIG. 10 (4), and cure the adhesive as shown in FIG. 10 (5). Then, the concrete and anchor bolts are fixed to each other to complete the attachment of the anchor bolts. Depending on the type of adhesive, it is not necessary to stir the anchor bolt, and there is a method of hitting the anchor bolt with a hammer to mix the adhesive and fixing the anchor bolt. In the present invention, a capsule (for example, MU anchor) containing the hammer-driving type adhesive is used, or a method of injecting the adhesive into the perforation with an injection gun is adopted.
[0003]
The biggest problem in the conventional construction of post-installed anchor bolts is that if there is a reinforcing bar in the concrete and a hole for the anchor bolt encounters this reinforcing bar, the post-installed anchor bolt will be It can not be installed (except when the length of the post-installed anchor is short). In order to secure the strength of the post-installed anchor bolts, it is necessary to have a predetermined embedding length in the concrete.
Due to the presence of rebar at a depth of mm, when the anchor bolt drilling encounters this rebar, it cannot take the regular length of the anchor bolt. This can be explained using the figure
In FIG. 11, D is the case where the anchor bolt 18 does not encounter the reinforcing bar 12, and the regular anchor length L of the anchor bolt 18 can be taken. On the other hand, E is perforation 1
The case where 0 encounters the reinforcing bar 12 and cannot take the regular anchor length L is shown. In addition, 26 is a surface of the concrete skeleton 9. Further, F is a fogging allowance.
A conventional method for solving this problem is shown in FIG.
As shown in (1), rebar 12 is separated from the place where it hits the rebar.
There was no choice but to drive the anchor bolt 18 at an angle of about 30 ° to avoid it. After hitting the anchor, the anchor bolt was bent as shown in FIG. 12 (2) by applying force so that the anchor bolt was vertical to the concrete surface. However, when the above-mentioned anchors are slanted, the position on the concrete surface is likely to be displaced, the construction is difficult, and the anchor bolts are locally applied to the anchor bolts, causing various problems such as strength problems. For this reason,
Good work could not be done unless it was a fairly skilled worker, and there was a failure in construction. In addition, the bolt diameter is M1
Although it is easy with 6 thickness, it is difficult for human beings with M20 or more, and at present, unavoidably large anchor bolts are unavoidable and the anchor is constructed by cutting the reinforcing bar with a diamond cutter. .
According to the present invention, when a post-construction anchor is constructed on a concrete floor surface, a wall surface, a ceiling surface, etc., when the reinforcing bar in the concrete and the hole for the anchor bolt encounter the reinforcing bar, the position of the anchor to be constructed is set. It is an object of the present invention to provide an anchor bolt that can be accurately installed at the position without change and has a predetermined strength, and an installation method thereof.
[0006]
SUMMARY OF THE INVENTION The present invention provides an anchor bolt to be post-installed on a concrete skeleton, which comprises a shaft core of a mounting screw portion protruding outside the concrete and an anchor bolt portion embedded in concrete. A composite anchor bolt having an eccentric shaft center.
The present invention also provides a first anchor bolt, which has a shorter anchor length than the cover allowance, and a mounting bolt portion which is longer than the cover allowance and is exposed to the outside of the concrete. A second anchor bolt not having the first anchor bolt, the first anchor bolt and the second anchor bolt,
It is a composite anchor bolt characterized in that it has a connecting member for connecting the anchor bolts.
Also, according to the present invention, the embedding depth of the first anchor bolt can be adjusted, the second anchor bolt and one end portion of the connecting member are integrally formed, and the other end portion of the connecting member is formed. It is a composite anchor bolt characterized in that a female screw portion that is screwed with the screw portion of the first anchor bolt is formed. Here, it is preferable to appropriately form the threaded portion over the entire surface of the first anchor bolt.
It is preferable that the distance between the respective axes of the first anchor bolt and the second anchor bolt is about 30 to 150 mm. It is preferable that the connecting member has a rectangular cross section, or a semi-circular shape having a flat upper side, or a circular shape.
The present invention also provides a first anchor bolt,
It is a composite anchor bolt in which the second anchor bolt and the connecting member are integrally formed. Here, a threaded portion may be formed on the entire outer circumference as appropriate.
Further, the present invention is a composite anchor characterized in that a plurality of anchor bolts are integrally arranged at a predetermined distance centering on a mounting screw portion protruding from the concrete skeleton. It is a bolt.
Further, the present invention is the composite anchor bolt, wherein the concrete embedding portions of the first anchor bolt and the second anchor bolt have a round bar shape or a reinforcing bar shape.
In the method of constructing the composite anchor bolt of the present invention, when the anchor bolt is post-constructed on the concrete frame, the anchor is encountered at the position where the anchor is to be properly constructed and the anchor where the reinforcement is not encountered. First
And a second perforation, a groove is provided between the first and second perforations, and two anchor bolts are integrally formed with the connecting member in the first and second perforations and the groove. It is characterized by constructing anchor bolts.
When the anchor bolt is post-installed on the concrete frame and the position of the reinforcing bar is not known, when the first drilling hole of the post-installing anchor encounters the reinforcing bar, the first drilling hole is looked into. , The situation of the encounter is (A)
Whether the perforation hit the rebar in the north-south direction, or (B)
Determine whether the perforation hit the east-west rebar or (C) the perforation hit east-west north-south direction, and in the case of (A), either the left or right diagonal direction of the rebar is selected. In the case of (B), either one of the vertical and diagonal directions of the reinforcing bar is selected, and in the case of (C), one of the vertical and diagonal directions of the reinforcing bar is selected. Then, in the selected direction, at a position spaced apart from the first perforation by a predetermined distance, a second perforation is formed at a regular depth deeper than the fogging margin, the first perforation and the second perforation. Forming a groove into which the connecting portion of the composite anchor fits between the perforations of the first anchor bolt, the first anchor bolt whose anchor length is shorter than the cover allowance, and the mounting screw which is longer than the cover allowance and goes out of concrete Second anchor bolt having no portion, and the first anchor Belt and the second composite anchor bolt respectively the first having a coupling member for coupling the anchor bolt drilling, is characterized in that it comprises the step of construction in the second perforation and the grooves.
[0015]
[Function] Normally, as shown in Fig. 1, the reinforcing bar is arranged like a grid, so if the position of the reinforcing bar is not known, the position of the position where the piercing of the construction anchor will encounter the reinforcing bar 10 after the first time. There are three types, A, B, and C in Figure 1. A is the case where the rebar in the north-south direction hits the hole, B is the case where the rebar is hit in the east-west direction, and C is the case where the rebar cross section in the north-south direction is hit. The black circles in the figure indicate the positions where the anchor holes have encountered the reinforcing bars. In the case of a general structure, the diameter of the reinforcing bar is about 10 to 22 mm and the pitch of the reinforcing bar is about 100 to 25 mm.
It is 0 mm.
The present inventor can determine whether the pattern is A, B, or C by looking through the perforation of the first post-installed anchor. The pattern A can be laterally or diagonally left and right, and the pattern B can be vertically or vertically diagonally. In the C pattern, it was found that there could be no reinforcing bars in the immediate up and down directions or the left and right oblique directions. Therefore, one of these directions is selected, and a certain distance X (about 30 to 30) from A, B, and C is selected.
It has been found that drilling a hole having a required anchor length can be performed with a probability of almost 100% by setting a rule to drill a drilled hole at a position (150 mm). White circles in the figure indicate the positions of the selected perforations. Focusing on this distance X, the present inventor has invented a composite anchor bolt and a method of constructing the composite anchor bolt described below.

Reference numeral 2 is a first anchor bolt having a shorter anchor length than the cover allowance, which is to be installed in a drilling hole that encounters a reinforcing bar, and an adhesive portion 3 having a groove on an outer peripheral surface for fixing the anchor bolt 2 and a connecting member. It is composed of a bolt portion 4 that is screwed into the female screw portion 6 of 5.
Reference numeral 7 is a second anchor bolt whose anchor length is longer than the cover allowance and which does not have a mounting screw portion which is exposed to the outside of the concrete, and which has a groove for fixing the anchor bolt 7 on its outer peripheral portion. It is composed of a portion 8 and the tip is fixed to the connecting member 5. 9 is a concrete frame.
In this composite anchor bolt, the portion above the upper surface of the connecting member 5 is outside the surface of the concrete skeleton 9. That is, it goes out into the air or water. On the other hand, the lower part from the upper surface of the connecting member 5 is embedded inside the concrete skeleton 9, and is fixed integrally with the concrete skeleton 9 by an adhesive at the bonding portions 3 and 8. The strength of the adhesive force with the concrete skeleton 9 is mainly determined by the surface area of the anchor bolt of the adhesive portion 8 × the adhesive strength per unit area. That is, the longer the length of the adhesive portion 8, the greater the adhesive force. Supplementally, the adhesive portion 3 of the first anchor bolt 3
Adhesive force is generated, but it is excluded from the calculation.
With this adhesive force, the pull-out force applied to the bolt portion 4 of the first anchor bolt 2 can be obtained. Further, in most cases, the shearing force applied to the bolt portion 4 can be obtained by the cross-sectional area of the anchor bolt embedded in the concrete skeleton. The material of the anchor bolt is SS400, stainless steel, aluminum, cast iron, S
CS or the like is used.
Next, an example of construction of this composite anchor bolt will be described with reference to the drawings. 3 (1), (2),
(3) and (4) are explanatory views showing sequential construction steps. First, when the anchor bolt is post-installed on the concrete skeleton 9 and the position of the reinforcing bar is unknown, if the first drilling 10 of the post-installing anchor encounters the reinforcing bar 12, then the first drilling 10 is looked into. The situation of the encounter was (A) whether the perforation hit the north-south rebar, (B) the perforation hit the east-west rebar, or (C) whether the perforation hits the north-south rebar. In the case of (A), one of the left and right or diagonal directions of the reinforcing bar is selected, and in the case of (B), one of the vertical and diagonal directions of the reinforcing bar is selected. Is selected, and in the case of (C), one of the upper and lower diagonal directions of the reinforcing bar is selected. And.
A predetermined distance X from the first perforation 10 in the selected direction.
The second perforation 11 is drilled at a predetermined depth beyond the reinforcing bar 12 at the position where the bar is placed. At this time, it is convenient to draw an arc of radius X around the first perforation 10 and mark the position of the next perforation 11 on this arc in the selected direction. In FIG. 3 (1), the point P is the position where the construction anchor is to be hit.
Next, as shown in FIG. 3B, the first perforation 1
A groove 14 into which the connecting member 5 is fitted is formed between 0 and the second perforation 11 with a disc sander equipped with a diamond cutter blade and a vibration drill. Then, after cleaning the first perforation 10, the second perforation 11 and the groove 14, the above-mentioned adhesive capsule 15 is inserted into the first perforation 10 and the second perforation 11, and the composite anchor bolt 1 according to the present invention. Hammer in. Then, the construction is completed by caulking the gap between the concrete frame 9 and the connecting member 5 and waiting for the adhesive to harden.
FIG. 4 shows an example in which the composite anchor bolt 1 of the present invention is applied to a wall surface, 16 is a concrete wall surface, and 1 is a concrete wall surface.
Reference numeral 7 indicates a support angle. 18 is a normal anchor bolt.
FIG. 5 shows an example in which the composite anchor bolt 1 of the present invention is applied to a floor surface, 19 is a concrete floor surface, and 2 is a concrete floor surface.
0 indicates a support unit. In FIGS. 6A and 6B,
The first anchor bolt 2 has a bolt portion 4 on its entire outer surface.
Has a structure formed. The second anchor bolt 7 and one end of the connecting member 5 are integrally formed, and the other end of the connecting member 5 is provided with a female screw portion 6 that is screwed with the bolt portion 4 of the first anchor bolt 2. Has been formed. With such a configuration, the relative positions of the first anchor bolt 2 and the second anchor bolt 7 can be adjusted according to the construction, which is convenient. When the first anchor bolt 2 and the connecting member 5 are integrally formed, the length of the first anchor bolt 2 is cut according to the depth to the reinforcing bar and the length is adjusted.
The shape of the composite anchor bolt of the present invention is not limited to that described above, and for example, the first anchor bolt, the second anchor bolt, and the connecting member are integrally formed, and FIG. As shown in FIG. 8, or with the mounting bolt portion 22 protruding outside the concrete frame as a center, the screw portion 21 is formed on the entire outer periphery as shown in FIG. Book anchor bolt 2
You may use suitably what arrange | positioned 3 integrally. Further, the concrete embedded portions of the first anchor bolt and the second anchor bolt may have a shape other than a screw, for example, a round bar shape or a reinforcing bar shape.
Although the adhesive type anchor bolt has been described above as an example, the composite anchor bolt of the present invention can also be applied to a post-installation anchor bolt of a driving type. Figure 9
Shows such an example. In FIG.
Reference numeral 24 is a driving type (wedge type) anchor bolt.
