Description

  The present invention relates to a vehicle stop block that is installed on an installation surface such as a parking lot and stops a vehicle at a predetermined position, and a hole cap used therefor.

  A vehicle stop block installed on the installation surface of a parking lot or the like for the purpose of stopping the vehicle at a predetermined position has a means for fixing the block to the installation surface so that the position will not shift or fall over even if a tire hits it. Various considerations have been made. Mainly, there is a demand for impact resistance so that the fixing means for the block does not loosen even if the tire strikes vigorously, and at the same time, improvement in workability is also demanded. As a conventional one, there is a method in which a hole is made in advance on an installation surface, and an anchor pin already embedded in a block is inserted therein to fill the hole with mortar or the like. However, this still has many problems in terms of anchor pin positioning, impact resistance, and workability. In contrast, a through hole is provided in the block, and the anchor pin is driven into the installation surface. The thing using the means to fix is created. For example, the following Patent Document 1 (Japanese Patent Application Laid-Open No. 11-159182) and the like make a shape in which the head of the anchor bolt and a predetermined portion of the anchor holder head are fitted together (for example, a tapered shape), It has a structure that can withstand more impact.

  However, according to Patent Document 1, the block is more difficult to move than the previously used car stop block, and the fixing performance is improved, but there is still room for improvement in the fitting state between the anchor bolt and the anchor holder. Therefore, when the tire collided strongly with the block, there was a problem that the bolt jumped up and damaged the muffler, the bumper and the like.

Also, if the hole cap protrudes from the upper surface of the block as before, it may hit the muffler or bumper, etc., and the muffler etc. may be scratched, or the hole cap may come off from the car stop or be damaged .
JP 11-159182 A

  The present invention eliminates the possibility of a car muffler etc. coming into contact with the hole cap, and prevents the hole cap from hitting the muffler or bumper to damage the muffler etc. It is an object to do.

[Claim 1]
The present invention has a flat top surface, a front surface provided with a reflector, a tubular shape in the receiving hole of the vehicle stopper block having a through hole in the vertical direction and the upper end of which is a receiving hole for a hole cap. A vehicle stop block having a hole cap having a plurality of leg portions, wherein the front portion inevitably faces the front surface of the vehicle stop block when the hole cap is attached to the receiving hole.

[Claim 2]
Further, the present invention is the vehicle stopper block according to claim 1, wherein the upper surface of the vehicle stopper block main body and the upper surface of the hole cap are flat.

  According to the present invention, since the upper surface of the hole cap and the upper surface of the block are not flat and projecting, there is no possibility that the muffler or the like of the car contacts the hole cap. Moreover, since the reflector provided on the front surface of the hole cap is exposed on the front surface of the vehicle stop block body, the hole cap can also function as a reflector.

It is the top view of the anchor holder 1, a sectional view, a side view, and a bottom view. FIG. FIG. 4 is a plan view, a front view, and a cross-sectional view of the car stopper block 21. It is explanatory drawing of the car stop. It is explanatory drawing of the car stop 60. FIG. FIG. 4 is a central longitudinal sectional view of the car stopper block 21. FIG. 4 is a plan view, a front view, a bottom view, and a side view of the hole cap 30.

  First, the anchor holder used for the vehicle stop block of the embodiment will be described with reference to FIGS. 1 and 2. The anchor holder of this example was made using polypropylene. FIG. 1 is a plan view (a), a sectional view (b), a side view (c), and a bottom view (d) of the anchor holder 1. As shown in the sectional view (b), the anchor holder 1 is composed of a holder head 2 and a holder tube 3. These can be created in one piece, but can also be combined after creating them separately. In this embodiment, the holder head 2 and the holder tube 3 are combined separately after being created. The holder head 2 includes a protrusion 4 having an inwardly extending ridge 5 on the upper part, a peripheral groove 6 on the outer side of the protrusion 4, a peripheral wall 7 provided on the outer side of the peripheral groove 6, and a lower end of the peripheral wall. It consists of a peripheral flange 8. In the present embodiment, four protrusions 4 are erected and are arranged so that two pairs face each other as shown in the plan view (a). A space surrounded by the four protrusions 4 and below the ridge 5 is a bolt head receiving hole 12, which is for containing the bolt head when the anchor bolt is inserted. Moreover, the circumferential groove 6 is a space for the protrusion 4 to be pushed outward when the bolt head at the time of inserting the anchor bolt passes. After the insertion, the movement of the protruding portion 4 to the outside can be locked by fitting the leg portion of the hole cap here. The description when inserting the anchor bolt will be described later. The flange portion 8 at the lower end of the holder head 2 is provided so that the holder does not easily come off from the concrete when the anchor holder is embedded in the block.

  The holder tube portion 3 includes a tube portion main body 14 and a holder neck portion 15 that is formed in a flange shape at the top and is fitted to the holder head 2. The inside of the tube portion main body 14 is a bolt when an anchor bolt is inserted. A bolt shaft receiving hole 13 is provided for receiving the shaft. An inner peripheral rib 11 is provided on the inner side, and a tapered rib 10 connected to the outer peripheral rib 9 on the lower surface of the holder neck 15 is provided on the outer side. The outer peripheral surface of the cylindrical portion main body 14 has a tapered shape whose diameter decreases in the downward direction. Thus, when the anchor bolt 40 is inserted, a downward force acting on the holder cylindrical portion 3 causes the cylindrical portion to be inward. The force is converted into a constricting force, and the holder cylinder portion 3 tightens the anchor bolt 40. The inner peripheral rib 11 on the inner side often appears in the plan view (a) and the bottom view (d). Since the inner diameter of the inner peripheral rib 11 is slightly smaller than the diameter of the bolt shaft portion 42 of the anchor bolt 40, when the anchor bolt is inserted into the bolt shaft portion receiving hole, the convex rib is crushed, so that the anchor bolt And improve the adhesion of the anchor holder. The outer peripheral rib 9 functions to reinforce the holder neck 15 that supports the holder head 2. The tapered rib 10 connected thereto is tapered downward, and this also serves to increase the strength of the anchor holder. Further, as shown in FIG. 2, the outer diameter of the holder cylinder portion 3 immediately below the holder neck portion 15 that becomes the boundary between the holder head portion 2 and the holder cylinder portion 3 is outside the lower end of the bolt head portion 41 of the anchor bolt 40. It is smaller than the diameter. Concrete enters directly under the outer edge of the bolt head 41 (outside the holder tube). Thereby, since the impact at the time of driving the anchor bolt can be received not only by the resin portion of the holder but also by the concrete portion immediately below the outer edge of the bolt head 41, the strength of the anchor holder can be increased. It is possible to prevent the anchor holder from being damaged during driving.

  FIG. 2 shows a state in which the car stopper block 21 of the embodiment of the present invention is fixed to the installation surface to form the car stopper 20. The car stopper includes an anchor holder 1 shown in FIG. 1, a car stopper block 21 according to an embodiment of the present invention in which the holder is embedded, an anchor bolt 40 inserted into the holder, and a hole cap 30 fitted into the holder. ing.

  First, the vehicle stop block 21 according to the embodiment of the present invention will be described. FIG. 3 is a plan view (a), a side view (b), and a front view (c) of the vehicle stopper block 21 of the present embodiment. As shown here, the car stopper block is a substantially rectangular parallelepiped having a substantially trapezoidal longitudinal section. Two hole cap receiving holes 27 are provided in the block upper surface 22, and the anchor holders 1 are respectively embedded therein. Thereby, the through hole 25 is formed. Further, there is a marking portion 28 near the center of the inclined portion 23, and a name marking sticker or the like can be attached thereto. An adhesive can be applied to the bottom surface 24.

  A method of forming the car stop block 21 is as follows. First, set the formwork (not shown) so that the bottom of the finished state is on top. The mold has a projection that can be formed with a hole cap receiving hole 27 in advance, and the holder head 2 of the anchor holder 1 can be joined to the mold, so that the anchor is attached to this portion of the set mold. Attach holder 1. In this embodiment, as shown in FIGS. 3A and 3B, two anchor holders 1 are attached to one block. The anchor holder is used for positioning so that the anchor bolt can be inserted straight, and for improving the impact resistance of the block itself by being in close contact with the anchor bolt. By embedding the anchor holder 1, a through hole 25 can be formed in the block 21 as shown in both FIGS. 3 (b) and 3 (c). In this embodiment, a boss for forming the expanded hole portion 26 in the anchor holder 1 is attached to the tip of the holder tube portion 3. Thereafter, the concrete is poured into the mold and demolded after curing. In this way, the vehicle stop block 21 of this embodiment in which the anchor holder 1 is embedded can be manufactured.

  FIG. 2 shows a state in which the anchor bolt 40 is inserted into the car stopper block 21 of the embodiment of the present invention thus formed. The anchor bolt 40 is entirely made of metal, and a bolt head 41 is integrally formed by forging or the like. The anchor bolt is driven into the installation surface by hitting with a hammer or the like from above or by using a driving machine such as a hammer drill. The anchor bolt 40 needs to be driven to such an extent that it can pass through the car stopper block 21 and be fixed to the ground below it, so that it must be somewhat longer than the height of the block. The driving waste generated when driving in can be accommodated in the expanded portion 26 of the block 21. Thereby, it can prevent that the block 21 is lifted from the ground by driving waste. The anchor bolt has a pointed tip in view of ease of driving operation.

  When the anchor bolt is driven, first, the bolt shaft portion 42 is inserted while crushing the inner peripheral rib 11 of the holder tube portion. Thereby, the adhesiveness of a holder and a bolt increases. Next, at the stage where the bolt head 41 passes through the protrusion 4, the protrusion 4 is once spread outward because the bolt head 41 passes through the portion of the protrusion 5. Then, after the bolt head 41 has passed through the protrusion 4, the protrusion 4 returns to its original position due to elasticity. In this way, the bolt head 41 is accommodated in the space of the bolt head receiving hole 12 in the holder head 2. At this time, the bolt head 41 is pressed from above by the ridge 5, so that the bolt head 41 does not jump above the protrusion 4. Further, as shown in FIG. 2, by fitting the leg portion 32 of the hole cap 30 into the circumferential groove 6 of the holder head 2, the force of the protrusion 4 to spread outward is suppressed, so that the bolt head It is possible to further prevent the portion 41 from jumping up.

  As shown in FIGS. 2 and 7, the hole cap 30 of the present invention includes a cap upper surface 31, leg portions 32, and a reflector 33. As described above, the hole cap 30 is fitted by fitting the leg portion 32 to the circumferential groove 6 of the holder head 2. The cap upper surface 31 has a planar shape, and the cap upper surface 31 and the block upper surface 22 become flat when fitted on the holder head 2. Since the cap does not protrude from the upper surface of the block, the vehicle body such as a muffler is not damaged even if the tire hits the block, and the cap is not damaged. Further, a well-known reflecting mirror is used for the reflector fitted on the front surface, so that it is possible to notify the driver of the presence of the block by being reflected by a car light or the like even in a dark place. Thus, the hole cap 30 of the present invention fulfills a number of functions with a single component. 7A is a plan view, FIG. 7B is a front view, FIG. 7C is a bottom view, and FIG. 7D is a side view.

  The vehicle stop block 21 of the present embodiment can be fixed to the installation surface by known means, for example, a means for attaching and fixing a known anchor member having a retaining function at the tip of the anchor bolt.

  In order to install the car stopper block 21 of the present embodiment, first, an adhesive is applied to the bottom surface of the car stopper block 21 and is placed at a predetermined installation place to be temporarily fixed. Next, the anchor bolt 40 is inserted into the through-hole 25 of the anchor holder 1 from above and driven into the installation surface using a hammer drill or the like. The driving is finished until the bolt head 41 is received in the bolt head receiving hole 12, and when the state shown in FIG. After that, if the hole cap 30 is fitted, it is completed. By performing this together with the two anchor holders, the car stopper 20 is fixed to the installation surface.

  Shown in FIG. 4 is a car stopper 50, which has a car stopper block 51 in which a cylindrical joint part 52 connected to the anchor holder 1 is embedded to form a vertical through hole on an installation surface with an anchor bolt 40. It is fixed and fitted with a hole cap 30. The height of the car stop block is usually 120mm, and the anchor holder 1 is made to correspond to this, so for higher blocks, use joint parts according to the height of the block By doing so, it can respond to each block of different height. Since the basic anchor holder 1 may be of the same shape, it can be used in various applications. In addition, although the joint part 52 of a present Example is externally fitted and joined to the front-end | tip of the anchor holder 1, as long as the height can be added, it may be a junction part of what shape. It is the same as the car stopper 20 described above except that the joint parts are joined.

  As a method for fixing the car stopper, a method in which the anchor bolt is not driven in from the top can be used as a method other than the above. Also in this fixing method, the vehicle stop block and the hole cap of the above embodiment can be used. As shown in FIG. 5, the anchor bolt 61 is first inserted into the anchor holder 1 before the car stopper block 21 is placed at the installation location. The anchor bolt 61 is a metal bolt having a normal hexagonal head 63. In this case, a plastic bolt head 66 is provided by sliding. Since this method does not drive anchor bolts onto the installation surface, a plastic head is sufficient in strength. When the bolt head 66 is properly seated in the bolt head receiving hole 12 in the holder head 2, the anchor bolt 61 is tightened with the nut 62 from the widened hole portion 26 of the car stopper block 21. Thus, the anchor bolt 61 is fixed to the anchor holder 1 by tightening with a nut from the bottom. After tightening with a nut in this way, a buried hole 64 for embedding a bolt tip projecting from the bottom surface 24 of the block 21 and fixing it to the ground at a predetermined installation location of a car stop is made, and a mortar 65, a bond, etc. Then, the bolt tip portion is embedded. Also by this fixing method, the vehicle stop block can be firmly fixed to the ground, and the effect of the anchor bolt structure of the present invention can be obtained, so that the impact resistance can be kept high. Further, since the anchor bolt is fixed to the vehicle stop block, there is no possibility of jumping out of the block due to an impact.

  FIG. 6 is a central longitudinal sectional view of the car stopper block 21. A marking portion 28 formed in the central portion of the inclined portion 23 has a concave curved surface shape. The curvature radius R in the longitudinal section of the concave curved surface of the marking portion 28 is set so that the tire of the assumed minimum diameter of the automobile does not contact (a curvature radius smaller than the minimum tire diameter). It is also possible to avoid contact with a tire of an automobile. A name sticker is usually affixed to this part. As a result, the name sticker affixed to this portion is not easily erased, and the sticker itself is difficult to peel off.

  As shown in FIG. 6, one plastic insert 70 for mounting the auxiliary anchor 71 is embedded in the center portion of the lower surface of the car stopper block 21. The auxiliary anchor is attached as necessary, and the car stopper block 21 may be installed without being attached. When installing the auxiliary anchor, before installing the block 21, the auxiliary anchor 71 is driven into the insert 70 in advance and installed by screwing or the like, and thereafter, a predetermined installation surface is opened, and an adhesive 73 such as bond or mortar is applied. The protruding portion of the auxiliary anchor 71 is embedded in the injected embedded hole 72. Thereby, a block can be temporarily fixed to an installation place, and more firm impact resistance can be given. A reinforcing bar, a bolt, etc. can be used as an auxiliary anchor.
