[Block fixed structure]
FIG. 9 is a front view of the block fixing structure of the embodiment of the present invention disassembled into the anchor bolt tubular member 1, the receiving member 30, the anchor bolt 40, the anchor 50, the cone 60, and the wheel stop block 70. FIG.
In the wheel stopper block 70, the anchor bolt cylindrical members 1 are embedded in the block holes 74h and 75h at the positions of the left and right cutouts 74 and 75, respectively. Anchor bolts 40 through which members 30 are inserted are inserted into anchor holes 81 and 82 of an installation surface 80, and anchors 50 having cones 60 dropped thereinto are screwed into anchor bolts 40 to install wheel stop blocks 70. Affixed to surface 80 .
In this case, an adhesive is further applied to the portion of the installation surface 80 on which the bottom surface of the wheel stop block 70 is placed, and the anchor block 70 is fixed to the installation surface 80 by the anchor bolts 40 screwed into the anchors 50 and the adhesive.

10 and 11 are vertical cross-sectional views of the anchor bolt cylindrical member 1, the anchor bolt 40, the anchor 50, and their vicinity in the process of fixing the wheel stop block 70 to the installation surface 80 with the anchor bolt 40 and the anchor 50. FIG. 10(a) shows a state in which the anchor bolt 40, which is screwed into the anchor 50 by inserting the receiving member 30 into the bolt shank 42, is set in the anchor bolt cylindrical member 1, and FIG. A state in which the anchor 50 plunges into the anchor hole 81 (82) by striking the bolt head 41 of the anchor bolt 40 is shown, and FIG. , and FIG. 11(b) shows a state in which screwing of the anchor bolt 40 into the anchor 50 is completed.
In the figure, 76 is an expansion hole, and P1 is a bolt head when the thin portion 33a of the receiving member 30 (wall contact portion 33) starts contacting the holding wall surface 13a of the tubular member main body 10 (receiving member holding portion 13). P2 is the vertical (Z-direction) position of the top end of the bolt head 41 when screwing of the anchor bolt 40 into the anchor 50 is completed (first position). second position).
The expansion hole 76 is a hole continuous with the second insertion hole SA2 formed when the wheel stopper block 70 is manufactured, and has a truncated cone shape.
In manufacturing the wheel stop block 70, the anchor bolt cylindrical member 1 having the fixed rod attached to the lower end of the cylindrical portion 17 is set in a formwork, concrete is poured into the formwork and hardened, and the fixed rod is removed from the hardened concrete. is withdrawn, the formwork is removed, and the expansion hole 76 is the hole formed in the block of hardened concrete by withdrawing the fixed rod.

A method of fixing the wheel stop block 70 to the installation surface 80 by the anchor bolts 40 and the anchors 50 will be described below.
First, as a preliminary preparation, a reference line (marker) or the like indicating the installation position of the car stop block 70 is provided on the installation surface, and an adhesive is applied to the installation surface 50 where the car stop block 40 is to be placed.
When the preparation is completed, the wheel stop block 70 is placed on the installation surface 80 along the reference line or the like indicating the installation position, and the concrete drill chucked by the screwdriver is inserted into the second insertion hole SA2 of the anchor bolt cylindrical member 1, Anchor holes 81 and 82 are drilled in the installation surface 80 with a concrete drill.
At this time, since the diameter of the rib tip hole 19 formed by the inner ribs 18a to 18h of the cylindrical portion 17 is smaller than the outer diameter of the concrete drill, the tips of the inner ribs 18a to 18h are scraped off by the concrete drill. The diameter of the tip hole 19 will be the same as the outer diameter of the concrete drill.
Next, the receiving member 30 is inserted into the bolt shank 42 of the anchor bolt 40 , the cone 60 is inserted into the anchor 50 , and the anchor bolt 40 is screwed until the lower surface of the anchor bolt 40 hits the upper surface of the projection 61 of the cone 60 .
After that, as shown in FIG. 10(a), the lower part of the anchor 50 into which the anchor bolt 40 is screwed is passed through the claw portion space of the tubular member upper portion 20 and into the tubular member main body 10 (holding space HK). , and set the anchor 50 to the anchor bolt tubular member 1 .
In this case, the diameter of the rib tip hole 19 widened to the outer diameter of the concrete drill is slightly larger than the outer diameter of the sleeve 52 (tapered portion 52b) of the anchor 50, and the lower portion of the anchor 50 (sleeve 52) has ribs 18a to 18h. is inside the

Then, the bolt head 41 of the anchor bolt 40 is hammered with a hammer, and as shown in FIG. plunge into.
At this time, although the outer diameter of the flange 51 of the anchor 50 is slightly larger than the diameter of the rib tip hole 19, the shaved inner ribs 18a to 18h are easily deformed, and the plunge of the flange 51 by striking the bolt head 41 is prevented. The inner ribs 18a to 18h scraped off are deformed to further widen the rib tip holes 19, and the flange 51 easily passes through the inner ribs 18a to 18h.
In addition, the outer diameter of the concrete drill is slightly larger than the outer diameter of the sleeve 52 of the anchor 50, and the inner diameter of the anchor hole 81 (82) is also slightly larger than the outer diameter of the sleeve 52. By hammering, the anchor 50 plunges into the anchor hole 81 (82).
In this case, since the diameter of the first insertion hole SA1 of the receiving member 30 is larger than the outer diameter of the bolt shaft portion 42 of the anchor bolt 40, the receiving member 30 slides down the bolt shaft portion 42 (body portion 42b). , the collar portion 32 or the reinforcing ribs 34a to 34h come into contact with the claws 23a to 23d of the cylindrical member upper portion 20 (FIG. 10(b) shows a state in which the reinforcing ribs 34a to 34h contact the claws 23a to 23d). ing).

After that, as the hammer continues to strike the bolt head 41 , the anchor 50 plunges into the anchor hole 81 ( 82 ) and the anchor bolt 40 descends, so that the lower surface of the bolt head 41 touches the receiving member 30 . When it comes into contact with the upper surface of the bolt head contact portion 31 and continues to be hammered, the flange portion 32 pushes apart the hook portions of the claw portions 23a to 23d of the cylindrical member upper portion 20 to widen the claw portion space, and the receiving member 30 is removed. As shown in FIG. 11(a), the thin wall portion 33a of the wall surface contact portion 33 contacts the holding wall surface 13a of the cylindrical member main body 10 (receiving member holding portion 13), and the flange 51 of the anchor 50 comes into contact with the anchor. It reaches the use hole 81 (82).
Since the outer diameter of the flange 51 is larger than the inner diameter of the anchor hole 81 (82), even if the hammer is continuously hammered into the bolt head 41, the flange 51 does not reach the installation surface around the anchor hole 81 (82). 80, the anchor 50 does not plunge into the anchor hole 81 (82) any more, the descent of the receiving member 30 is stopped, and the hammering into the bolt head 41 is completed.
In other words, the worker continues to strike the bolt head 41 with the hammer, but when the receiving member 30 stops descending, the thin wall portion 33a of the wall surface contact portion 33 contacts the holding wall surface 13a, and the flange 51 has reached the anchor hole 81 (82), and finishes hammering into the bolt head 41.
At this time, the thin portion 33a of the wall contact portion 33 contacts the holding wall surface 13a in a slightly elastically deformed state, and the upper surface of the bolt head 41 is at position P1 (first position).

Next, the bolt head 41 of the anchor bolt 40 is rotated with a wrench in the tightening direction, and the bolt shaft 42 (male threaded portion 42a) is screwed into the female threaded portion 52a of the anchor 50 (sleeve 52).
Due to the tightening pressure of the anchor bolt 40 due to this screwing, a compressive force in the vertical direction (Z direction) acts on the receiving member 30, the thin portion 33a of the wall contact portion 33 is deformed, and the receiving member 30 descends. .
At this time, the deformation of the thin portion 33a shifts from elastic deformation to plastic deformation, and the compressive force acting on the receiving member 30, that is, the tightening pressure of the anchor bolt 40 increases as the amount of deformation of the thin portion 33a increases.
At the same time, the anchor bolt 40 (bolt shaft portion 42) presses the upper surface of the convex portion 61 of the cone 60 to move the cone 60 downward, and the peripheral surface of the truncated cone portion 62 moves the inner wall of the expanded portion 52c of the anchor 50 to the radius. The inner diameter of the expanded portion 52c is expanded, and the outer peripheral surface of the expanded portion 52c is pressed against the inner wall of the anchor hole 81 (82).
As the bolt shaft portion 42 (male thread portion 42a) continues to be screwed into the anchor 50 (female thread portion 52a), plastic deformation of the thin portion 33a progresses and the tightening pressure of the anchor bolt 40 increases. further descends, and as shown in FIG. When the hook portions of the claw portions 23a to 23d cover the top surface of the flange portion 32, the plastic deformation of the thin portion 33a of the wall contact portion 33 reaches its limit, and the receiving member 30 is no longer deformed. can no longer be screwed into the anchor 50, the upper surface of the bolt head 41 reaches position P2 (second position), and the screwing of the bolt shaft 42 into the anchor 50 is completed.
At this time, the thin portion 33a of the wall surface contact portion 33 is the distance δ, for example, 2 mm to 5 mm (preferably 3 mm to 4 mm), and the tightening pressure of the anchor bolt 40 is a magnitude suitable for fixing the wheel stop block 70 to the installation surface 80 (does not damage the wheel stop block 70 or the anchor bolt cylindrical member 1). or force to press the wheel stop block 70 against the mounting surface 80 as firmly as possible without crushing the threads of the male threaded portion 42a and the female threaded portion 52a), for example, 1/5 to 2 of the bending strength of the wheel stop block 70. /3 (preferably 1/4 to 1/2).
In the anchor 50, the cone 60 moves downward δ, and the pressing force with which the outer peripheral surface of the expanded portion 52c presses against the inner wall of the anchor hole 81 (82) is the same as when the car tire collides with the car stop block 70. The impact force is large enough to resist the pull-out force that tries to pull out the anchor 50 from the anchor hole 81 (82).
In other words, the operator continues to screw the bolt shaft portion 42 into the anchor 50, but the hook portions of the claws 23a to 23d cover the upper surface of the collar portion 32, and the bolt shaft portion 42 cannot be screwed into the anchor 50. By this, it is sensed that the tightening pressure of the anchor bolt 40 has reached a level suitable for fixing the wheel stop block 70 to the installation surface 80, and the screwing of the bolt shank 42 into the anchor 50 is completed.

As described above, in the block fixing structure shown in FIG. 9, the anchor bolt tubular member 1 is embedded in the wheel stopper block 70, and the anchor bolt tubular member 1 includes the tubular member main body 10 and the tubular member upper portion 20. The member main body 10 includes a second insertion hole SA2 through which the bolt shaft portion 42 of the anchor bolt 40 is inserted, and a receiving member holding portion 13 having a holding wall surface 13a. A receiving member 30 is inserted through the bolt shaft portion 42 of the bolt 40. The receiving member 30 includes a bolt head contact portion 31 which is a thick portion, a flange portion 32, and a wall contact portion 33 having a thin portion 33a. , the anchor bolt 40 screwed into the anchor 50 is driven through the second insertion hole SA of the anchor bolt cylindrical member 1, the anchor 50 enters the anchor hole 81 (82), and is driven into the bolt head 41. As a result, the lower surface of the bolt head 41 contacts the upper surface of the bolt head contact portion 31, the claw portions 23a to 23d of the cylindrical member upper portion 20 are spread by the flange portion 32, and the thin portion 33a of the wall contact portion 33 contacts the holding wall surface 13a and the upper surface of the bolt head 41 comes to position P1 (first position), the bolt shaft 42 (male thread 42a) is screwed into the female thread 52a of the anchor 50 (sleeve 52), As a result, the thin portion 33a of the wall contact portion 33 is deformed, the receiving member 30 is lowered, and the upper surface of the bolt head portion 41 is lowered to the position P2 (second position) (at this time, the claw portions 23a to 23d are at their original positions). and covers the collar portion 32), and screwing is performed until the deformation of the thin portion 33a reaches its limit and the receiving member 30 no longer deforms. It can be fixed to the installation surface 80 as firmly as possible, and if the anchor bolt 40 is screwed too much into the anchor 50, the threads of the male threaded portion 42a and the female threaded portion 52a will be crushed, and the anchor bolt cylindrical member 1 and the wheel stop block 70 will be damaged. As a result, it is possible to prevent the wheel stop block 70 from becoming unfixed to the installation surface 80. - 特許庁

[Fixing the car stop block with an anchor pin]
A description will be given of a case in which the bollard blocks are fixed by anchor pins instead of anchor bolts and anchors.
When the installation surface on which the car stop block is installed is not a concrete surface but a surface that is not as hard as a concrete surface such as an asphalt surface, the car stop block is fixed to the installation surface by anchor pins instead of anchor bolts and anchors.
12(a) is a plan view of the anchor pin, and FIG. 12(b) is a front view of the anchor pin. In the figure, 90 is the anchor pin, 91 is the head portion, 91a is the bowl portion, and 91b is the step portion. , 92 is a shaft portion, and 93 is a tip portion.
The anchor pin 90 is a metal rod-like member with a circular cross section for fixing the wheel stop block to the installation surface, and is composed of a head portion 91 , a shaft portion 92 and a tip portion 93 .
The head portion 91 includes a bowl portion 91a and a stepped portion 91b protruding upward from the upper surface of the bowl portion. This is the portion that comes into surface contact with the wall surface 13a.
The stepped portion 91b is a portion that receives impact from the driving machine when the anchor pin 90 is driven into the installation surface by the driving machine. 91b is stored.
The shaft portion 92 is inserted through the second insertion hole SA2 of the anchor bolt cylindrical member 1 (cylindrical member main body 10) embedded in the car stop block, and a vertical hole in the car stop block that is continuous with the second insertion hole SA2. The outer diameter of the shaft portion 92 is the same as the diameter of the rib tip hole 19 formed by the tip ends of the inner ribs 18a to 18h of the cylindrical member main body 10. As shown in FIG.
A tip portion 93 is a tip portion of the anchor pin 90 that is continuous with the shaft portion 92, and has a sharp conical shape so that the anchor pin 90 can be driven into an installation surface such as an asphalt surface.

FIG. 13 is a front view of the structure for fixing the bollard block using anchor pins, disassembled into the anchor bolt cylindrical member 1, the anchor pin 90, and the bollard block 70. In the figure, 80' is the installation surface, and FIG. The same symbols are attached to the same ones as the block fixing structure shown.
The block fixing structure using anchor pins is similar to the block fixing structure using anchor bolts and anchors (see FIG. 9). In the wheel stop block 70, the anchor bolt cylindrical members 1 are embedded in the block holes 74h and 75h at the positions of the left and right cutouts 74 and 75, respectively. The anchor pin 90 is inserted, and the tip portion and part of the shaft portion of the anchor pin 90 are driven into the installation surface 80' such as an asphalt surface, thereby fixing the wheel stopper block 70 to the installation surface 80'.
Specifically, the anchor block 70 is fixed to the installation surface 80' by the anchor pin 90 as follows.
First, the tip portion 93 and the shaft portion 92 of the anchor pin 90 are inserted through the second insertion hole SA2 and the expansion hole 76 of the anchor bolt tubular member 1 (tubular member main body 10), and the tip of the tip portion 93 is positioned on the installation surface 80'. The holder (part to be hit) of the driving machine is applied to the stepped portion 91b of the head 91 of the anchor pin 90, and the anchor pin 90 is driven by the driving machine, and the anchor pin 90 is installed from the tip 93. Plunge into surface 80'.
By driving the anchor pin 90, the anchor pin 90 enters the installation surface 80' from the tip portion 93, the head portion 91 gradually descends, and the bowl portion 91a is inserted into the peripheral wall portion 21 of the cylindrical member upper portion 20. It enters, spreads the claws 23a, 23b, 23c, and 23d and crawls under them. As a result, the claws 23a, 23b, 23c, and 23d prevent the anchor pins from jumping up due to the impact of the tire hitting the car stop block after the car stop block is installed.
Then, the anchor pin 90 is driven until the peripheral surface of the bowl portion 91a contacts the holding wall surface 13a of the cylindrical member main body 10. As shown in FIG.
At this time, the portion of the peripheral surface of the bowl portion 91a excluding the upper portion contacts the holding wall surface 13a of the cylindrical member main body 10, and a portion of the head portion 91 (bowl portion 91a) is held by the receiving member holding portion 13, and the claw portion 23a is held. , 23b, 23c, and 23d cover the upper surface of the bowl portion 91a, and the stepped portion 91b is accommodated in the peripheral wall portion 21 of the upper portion 20 of the tubular member.

When the anchor pin 90 is driven by the driving machine as described above, since the outer diameter of the shaft portion 92 of the anchor pin 90 is the same as the diameter of the rib tip hole 19, the shaft portion 92 of the anchor pin 90 is Movement in the diametrical direction (X, Y directions) is restricted by the eight inner ribs 18a-18h.
As a result, in the middle of driving the anchor pin 90, particularly in the initial stage of driving, if the tip of the tip portion 93 hits the aggregate in the installation surface 80' such as an asphalt surface and is not inclined, the anchor pin will not tilt. A shaft portion 92 of the anchor pin 90 is guided by the eight inner ribs 18a to 18h. ' will be typed perpendicular to '.
On the other hand, in the middle of driving the anchor pin 90, particularly in the initial stage of driving, the tip of the tip portion 93 hits the aggregate in the installation surface 80' such as an asphalt surface and tries to shift, and the axis of the anchor pin 90 is shifted to the second position. When tilted with respect to the axis of the insertion hole SA2, the inner rib on the side opposite to the side on which the head 91 tilts among the inner ribs 18a to 18h is pushed by the shaft portion 92 and deformed, and the anchor pin 90 is tilted and driven. It will happen.
As a result, while the anchor pin 90 is being driven into the installation surface 80', it is possible to prevent the wheel stop block 70 from deviating from its initial position on the installation surface 80'.
Further, when the driving of the anchor pin 90 into the mounting surface 80' is completed, the bowl portion 91a is held by the receiving member holding portion 13 of the tubular member main body 10. Since the holding wall surface 13a of the holding portion 13 is also the same spherical surface, even if the anchor pin 90 is driven into the installation surface 80' at an angle, the anchor pin 90 is perpendicular to the installation surface 80'. As in the case of driving, the peripheral surface of the bowl portion 91a is in surface contact with the holding wall surface 13a of the receiving member holding portion 13, and the impact force from the bowl portion 91a to the receiving member holding portion 13 due to the impact of the driving machine is It is distributed over the entire holding wall surface 13a.
As a result, even if the driving of the anchor pin 90 by the driving machine is continued even after the bowl portion 91a of the anchor pin 90 contacts the receiving member holding portion 13, the receiving member holding portion 13 will not be damaged by the striking of the driving machine from the bowl portion 91a. The receiving member holding portion 13 (cylindrical member main body 10) is prevented from being damaged and the wheel stop block 70 from being damaged or cracked due to the impact force.

The receiving member, the cylindrical member for the anchor bolt with the receiving member, the block fixture, and the block fixing structure of the present invention are such that the anchor bolt is inserted through the cylindrical member embedded in the block, and the anchor bolt is accommodated in the cylindrical member. Then, when the block is fixed to the concrete surface by screwing the anchor bolt into the anchor driven into the concrete surface, etc., the degree of pressing of the anchor bolt against the block can be visually confirmed from the outside. , the screw thread of the bolt can be prevented from being crushed and the cylindrical member and the block can be prevented from being damaged, and can be used as a block such as a wheel stop block for stopping a vehicle at a predetermined position.
