Description

  The present invention is a vehicle stop block that is installed on the floor surface of a garage and contacts a vehicle tire, and is integrated with the vehicle stop block so as to penetrate a fixed pile used when the vehicle stop block is installed on the floor surface of the garage. It is related with the through-hole member with which it is provided.

  In order to define the parking position of the vehicle in the garage, a car stop block is installed on the floor surface of the garage. By bringing the vehicle tire into contact with the vehicle stop block, it is possible to define the parking position of the vehicle and prevent the vehicle from colliding with other vehicles, buildings, etc., or the tire from falling into a groove or the like. .

  Therefore, the vehicle stop block needs to have a structure that is not easily deformed or moved by the contact of the vehicle tire.

  Therefore, the conventional car stop block is made of concrete for easy molding and low cost, and is firmly fixed to the floor of the garage via fixed piles that penetrate vertically. (For example, refer to Patent Document 1).

  However, since the concrete car stopper block is poor in plasticity, if the fixed pile is directly driven from the upper surface to the floor surface of the garage, the car stopper block is cracked. For the same reason, it is also difficult to drill a through hole through which a fixed pile passes after molding.

  For this reason, when manufacturing a concrete car stopper block, the concrete before solidification is poured into the mold with the through-hole members arranged at predetermined positions in the mold, and the mold is removed after the concrete is solidified.

The through-hole member used for the vehicle stop block includes a cylindrical portion through which the shaft portion of the fixed pile penetrates below the storage portion that stores the head portion of the fixed pile. The upper surface of the storage portion is closed by the lid after the fixed pile has been driven.

  As described above, the through-hole member used for the car stopper block includes a storage portion and a cylindrical portion, and has a lid that is detachable on the upper surface of the storage portion, and has a relatively complicated shape. It is conceivable to form the hole member by resin molding.

  However, the through-hole member is disposed in advance in a predetermined position in the mold before the concrete is poured when the car stopper block is molded, and receives a compressive force by the concrete poured into the mold. For this reason, when a through-hole member is formed using a plastic resin as a raw material, the storage portion and the tubular portion contract due to the compressive force of the concrete poured into the mold.

  The cross-sectional shape of the hollow portion of the cylindrical portion is slightly larger than the cross-sectional shape of the shaft portion of the fixed pile so that the driving direction of the fixed pile can be guided. For this reason, when a cylindrical part shrink | contracts with the compressive force of concrete, the cross-sectional shape of a hollow part will become smaller than the cross-sectional shape of the axial part of a fixed pile, and the axial part of a fixed pile cannot be penetrated to a cylindrical part. .

  In general, concrete products including car stopper blocks are steam-dried in a steam environment at 80 to 100 ° C. At this time, the plasticity of the cylindrical portion made of resin increases, and the cylindrical portion is more easily contracted by the compressive force of the concrete. Become.

  In order to prevent this, it is conceivable to increase the thickness of the cylindrical portion or to form a rib on the outer surface of the cylindrical portion, but the amount of resin required for forming the through-hole member increases, which reduces the cost. There is a problem that causes an increase.

  In addition, since the resin molded product has a high surface smoothness and low affinity with concrete, a gap is formed between the resin tubular part and the concrete part, and cracks may occur during installation or use of the car stopper block. There is a problem that can cause it.

  The object of the present invention is to make the storage part for storing the head of the fixed pile made of resin, and to make the cylindrical part through which the shaft part of the fixed pile penetrates the metal as a material. It is possible to give the tubular part sufficient strength that it does not shrink due to the compressive force of the concrete without incurring rise, and it can prevent cracking during installation and use, and the shaft part of the fixed pile It is in providing the vehicle stop block which can be reliably penetrated to a cylindrical part, and the through-hole member for vehicle stop blocks.

  The vehicle stopper block according to the present invention includes a resin storage portion that stores the head of the fixed pile, a metal cylindrical portion that has an upper end fixed to a hole in a bottom surface of the storage portion, and a shaft portion of the fixed pile penetrates. It is characterized in that it is formed by pouring concrete into a formwork provided with a through-hole member made of and having the through-hole member arranged at a predetermined position.

  Further, the through hole member for the vehicle stop block according to the present invention has a resin storage portion for storing the head portion of the fixed pile, and an upper end portion fixed to the hole portion on the bottom surface of the storage portion, and the shaft portion of the fixed pile passes therethrough. And a metal cylindrical portion.

  In this configuration, the storage portion for storing the head of the fixed pile is made of resin, and the cylindrical portion through which the shaft portion of the fixed pile passes is made of metal, and the upper end of the cylindrical portion The portion is fixed to the hole in the bottom surface of the storage portion. Therefore, the storage portion is formed by resin molding that easily forms a relatively complicated shape, and the cylindrical portion that should guide the driving direction of the shaft portion of the fixed pile is formed of a metal material having sufficient strength.

  According to the present invention, the storage portion that stores the head portion of the fixed pile is made of resin, so that the storage portion can have a relatively complicated shape and the cylindrical portion has sufficient strength. By using a metal material as the material, it is possible to secure a hollow portion through which the shaft portion of the fixed pile penetrates even if compressive force is applied from the concrete poured into the mold during the manufacture of the car stopper block. The driving direction can be accurately guided.

  In particular, even when concrete is solidified by steam drying, the plasticity of the metallic cylindrical portion does not increase, and the cylindrical portion can be reliably prevented from contracting.

  In addition, the surface of a metal pipe such as an aluminum alloy that is the material of the cylindrical part has low smoothness and high affinity with concrete, so that a gap is formed between the solidified concrete and the cylindrical part. No cracking can be prevented during installation or use.

  FIG. 1 is an assembly view showing a configuration of a through hole member 10 for a car stopper block according to an embodiment of the present invention. The through-hole member 10 includes a storage portion 1, a lid body 2, and a cylindrical portion 3. The storage part 1 and the lid body 2 are formed by resin molding. As an example, the storage unit 1 includes an upper step portion 1A, a middle step portion 1B, and a lower step portion 1C each having a cylindrical shape whose outer diameters are sequentially reduced, and the upper and lower surfaces are open. A lid 2 is detachably fitted to the upper surface of the storage unit 1. A plurality of ribs 11 each having a wedge shape are formed on the outer peripheral surfaces of the middle step portion 1B and the lower step portion 1C. A plurality of flanges 12 are formed at the lower end of the upper stage 1A. A plurality of vertical slits 13 are formed in the lower step portion 1C.

  The cylindrical portion 3 is formed by cutting a metal cylindrical pipe such as an aluminum alloy into a predetermined length. As an example, the upper end portion 31 of the cylindrical portion 3 is formed with two locking holes 32. The upper end portion 31 of the cylindrical portion 3 is inserted from the bottom surface side of the storage portion 1 into the hole portion 16 opened to the bottom surface of the storage portion 1 including the portion where the locking holes 32 are formed.

  FIG. 2 is a cross-sectional view of the through-hole member 10. Inside the storage portion 1, a fitting portion 14, a head storage portion 15, and a hole portion 16 are formed in this order from top to bottom. The inner diameter of the fitting portion 14 is substantially equal to the outer diameter of the lid body 2. A recess 17 is formed in the fitting portion 14 over the entire circumference. By fitting the protrusion 21 (see FIG. 1) into the recess 17, the lid body 2 is fitted and held in the fitting portion 14.

  The inner diameter of the head storage portion 15 is sufficiently larger than the outer diameter of the head 41 of the fixed pile 4. A step portion 18 is formed between the head storage portion 15 and the hole portion 16. The inner diameter of the stepped portion 18 is smaller than the outer diameter of the head 41 of the fixed pile 4 and slightly larger than the outer diameter of the shaft portion 42. The inner diameter of the hole portion 16 is substantially equal to the outer diameter of the cylindrical portion 3. The inner diameter of the cylindrical portion 3 is slightly larger than the outer diameter of the shaft portion 42 of the fixed pile 4.

  As an example, protrusions 19 are formed at two locations on the inner peripheral surface of the hole 16. When the upper end portion 31 of the tubular portion 3 is inserted into the hole portion 16, the protrusion 19 is fitted into the locking hole 32 of the tubular portion 3. Thereby, the upper end portion 31 of the cylindrical portion 3 is fixed to the hole portion 16.

  Since the storage portion 1 is formed of resin as a raw material and the plurality of slits 13 are formed in the lower step portion 11 </ b> C, when the upper end portion 31 of the cylindrical portion 3 is inserted into the hole portion 16, the projection 19 The portion having the protrusion 19 in the lower step portion 11 </ b> C is elastically deformed to the outside by the contact between the cylindrical portion 3 and the outer peripheral surface of the cylindrical portion 3. Thereby, the upper end portion 31 of the cylindrical portion 3 can be easily inserted into the hole portion 16.

  The inner diameter of the hole portion 16 is slightly smaller than the outer diameter of the tubular portion 3, and the upper end portion 31 of the tubular portion 3 is press-fitted into the hole portion 16 and fixed to the hole portion 16. Good. In this case, it is not necessary to form the locking hole 31 in the cylindrical portion 3, and it is not necessary to form the slit 13 and the protrusion 19 in the storage portion 1.

  Moreover, although the accommodating part 1 is exhibiting the complicated shape compared with the cylindrical part 3, it can be formed easily and cheaply by resin molding. On the other hand, the cylindrical portion 3 having a cylindrical shape can be easily and extremely inexpensively formed by cutting a pipe into a predetermined length. Since the cylindrical part 3 is metal, it can obtain sufficient intensity | strength with thin thickness compared with the case where it forms with resin.

  In addition, the cylindrical part 3 does not necessarily need to be a cylindrical shape. The cross-sectional shape of the hollow portion of the cylindrical portion 3 is not necessarily similar to the cross-sectional shape of the shaft portion 42 of the fixed pile 4 as long as the shape is substantially circumscribed to the shaft portion 42 of the fixed pile 4.

  FIG. 3 is a view for explaining a manufacturing method of the car stopper block 20 using the through hole member 10. When manufacturing the vehicle stop block 20 using the through-hole member 10, first, the mold 50 that defines the outer diameter of the vehicle stop block 20 is installed with the upper surface side of the vehicle stop block 20 facing down. As an example in the mold 50, the concrete before solidification is poured into the mold 50 in a state where the through-hole members 10 are arranged upside down at two predetermined positions.

  The formwork 50 is configured by at least the upper surface of the car stopper block 20 and the surfaces corresponding to the four side surfaces.

  At this time, a compressive force acts on the outer peripheral surface of the through-hole member 10 from the concrete. Since the housing part 1 of the through-hole member 10 is made of resin, it shrinks due to the compressive force acting from the concrete. However, since the inner diameter of the head storage portion 15 is sufficiently larger than the outer diameter of the head 41 of the fixed pile 4, the head 41 of the fixed pile 4 cannot be stored. On the other hand, since the cylindrical portion 3 of the through-hole member 10 is made of metal, it does not shrink due to the compressive force acting from the concrete, and the shaft portion 42 of the fixed pile 4 cannot be stored.

  The car stopper block 20 is formed by removing the mold 50 after the concrete is solidified. In the vehicle stop block 20, the through hole member 10 is used as a through hole through which the fixed pile 4 should pass.

  A plurality of flanges 12 are formed on the outer periphery of the through-hole member 10. For this reason, even if the concrete shrinks to some extent when solidified, the collar portion 12 does not come into contact with the concrete positioned above, and the through-hole member 10 does not come out of the car stopper block 20 upward.

  Even when the concrete in the mold 50 is solidified by steam drying, the plastic cylindrical portion 3 does not increase in plasticity and the cylindrical portion 3 does not shrink.

  Further, the surface of a metal pipe made of an aluminum alloy or the like as a material for the cylindrical portion 3 has low smoothness and high affinity with concrete. For this reason, a gap is not formed between the solidified concrete and the cylindrical portion 3, and it is possible to prevent the occurrence of cracks during installation or use of the car stopper block 10.

  FIG. 4 is a diagram for explaining a method of installing the vehicle stop block 20. When installing the car stopper block 20, the car stopper block 20 is placed at a predetermined position on the floor surface 60 of the garage, and the shaft portion 42 of the fixed pile 4 is inserted into the through hole member 10 from above. Thereafter, the head 41 of the fixed pile 4 is hit with a hammer from above, and the shaft portion 42 of the fixed pile 4 is driven into the floor surface 60 of the garage.

  As shown in FIG. 2, when the lower end portion of the head portion 41 of the fixed pile 4 comes into contact with the stepped portion 18 in the storage portion 1 of the through-hole member 10, the lower end portion of the head portion 41 of the fixed pile 4 and the floor surface of the garage The step portion 18 and the cylindrical portion 3 in the housing portion 1 of the through-hole member 10 are sandwiched between the first and second portions 60 and 60. As a result, the vehicle stop block 20 is fixed at a predetermined position on the floor surface 60 of the garage. Thereafter, the lid body 2 is fitted to the upper surface of the storage portion 1 of the through-hole member 10.

It is an assembly drawing which shows the structure of the through-hole member 10 for the vehicle stop block which concerns on embodiment of this invention. 3 is a cross-sectional view of a through-hole member 10.
