Description

  The present invention relates to a roadblocking barricade, and more particularly to a roadblocking barricade for a forced approaching vehicle.

  In recent years, for example, forced entry into airports and important buildings has frequently occurred due to runaway vehicles using cars all over the world. Therefore, it is an urgent task to eradicate runaway vehicles in order to ensure safety and peace from the harmful effects of these runaway vehicles. Conventionally, in order to forcibly stop these runaway vehicles, for example, a car tire puncture forcing tool (see Reference 1) in which a number of hollow fine needles are embedded in a prismatic sponge or a number of spikes are fixed to a belt. Vehicle entry blocking belts (refer to Document 2) and vehicle stop devices (refer to Document 3) in which hollow needles are implanted upwards on an extendable arm member are known.

  The conventional vehicle stop device is designed to stop the vehicle by damaging the pneumatic tire of the vehicle by laying it on the road surface, and has the advantage of being able to immediately respond to an emergency situation and reliably stopping the vehicle Have However, for vehicles that are permitted to pass, it is necessary to remove or dismantle the vehicle entry prevention device each time the vehicle is passed, and the operation of re-laying must be repeated when cracking down. There was a point.

  In addition, steel electric or hydraulic vehicle intrusion prevention devices (TT280, TC14, manufactured by Sojitz Avisys Corporation: see non-patent literature) are known.

  However, since the electric or hydraulic vehicle intrusion prevention device requires a separate power source, the manufacturing cost is high and a large installation work is required.

FIG. 1 shows an external perspective view of the entire roadblocking barricade 1 according to Embodiment 1 for carrying out the present invention. In FIG. 1, a barricade 1 is laid as an emergency line for inspecting violent criminals using automobiles on a road, for example. For example, the barricade 1 is manually assembled at a site where a police officer tries to make an emergency line on a road, and is laid so as to cross the entire width of the road.

  The barricade 1 is generally formed using a plurality of bases 2, a plurality of connecting members 6, a large number of spike members 15 and 18, and a large number of pole members 22 and 23.

  As shown in FIGS. 2 and 3, the base plate 2 is typically formed using a rectangular iron plate, and a large number of through holes 4 are dispersed on the board surface. In addition, the shape of the base | substrate 2 is not restricted to a rectangle, A parallelogram, a long ellipse, the polygon which has a parallel long side, etc. may be sufficient. The substrate 2 is not limited to an iron plate, and may preferably be a steel plate or a synthetic resin plate having high mechanical strength (rigidity). The dimensions (length × width × thickness) of the base 2 are, for example, 250 mm × 500 mm × 5 mm to 500 mm × 1000 mm × 10 mm, which is convenient for carrying and assembling work.

  The large number of through holes 4 provided in the base 2 are preferably arranged in a matrix. In this way, by regularly arranging a large number of through-holes 4 on the entire board surface of the base 2, a linear inclined wheel passage region described later in detail can be easily defined.

At least two or more base connection holes 5 are provided at the edge of each side of the base 2 according to the size of the base 2. In the board | substrate 2 shown in FIG. 1, the three board | substrate connection holes 5 are provided in the both ends and intermediate part of each edge | side. As shown in FIG. 4, the edges of adjacent sides of adjacent bases 2 are connected using metal connecting plates (connecting members) 6 provided with long holes 7 and 7 at both ends, respectively, A board 3 is formed. The strip-shaped board 3 forming the base of the barricade 1 shown in FIG. 1 has five bases 2 connected in series in the width direction of the road and two bases in the length direction of the road, for a total of 5 × 2 = 10 bases. 2 are connected by using a total of 39 connecting plates 6. In order to connect the adjacent bases 2 with the connecting plate 6, a pair of base connecting holes 5, 5 provided at the edge portions of the opposing sides of both bases 2 and the long holes 7, 7 at both ends of the connecting plate 6 are provided. The bolts 8 are inserted so as to overlap each other, and the base plate 2 is sandwiched between the head of the bolt 8 and a nut (not shown) that is screwed to the lower end of the bolt so as to be adjacent to each other. Both bases 2 are connected so as to be separable. In this base connection, instead of the connection plate 6 and the bolt 8, a U-shaped connection fitting (not shown) in which they are integrated is used, and the both leg bolts are connected to the edges of the opposite sides of the two bases 2. The two bases 2 may be connected by being fitted into a pair of base connecting holes 5 and 5 provided in the base plate.
The base connecting hole 5 may use the through hole 4.

  As shown in FIG. 1, two wheel passage areas 11, 11 extending linearly parallel to each other at an inclination angle from the front end to the rear end are defined on the board surface of the belt-like board body 3. Both wheel traffic areas 11, 11 both have a width that is slightly larger than the pneumatic tire width of both wheels of the automobile (vehicle) and extend in parallel with each other with an interval corresponding to the interval between the both wheels. By frequently changing the inclination angles of the two-wheel passage areas 11 and 11 with respect to the front end and the rear end of the belt-like disc body 3, it is possible to prevent the vehicle passage area from being read by a driver or the like of the forced approaching vehicle. Note that the wheel passage region may be a single wheel passage region (not shown) having a width corresponding to the width of the vehicle body of the automobile (vehicle).

  With the exception of two parallel wheel passage areas 11 and 11 defined on the surface of the belt-like board body 3, it is dispersed in the middle part 13 between both wheel passage areas and the outer parts 14 and 14 on both sides of both wheel passage areas. A bolt lower end portion 17 of a spike member 15 having a wedge-shaped pointed head 16 as shown in FIG. 5 and a spike member having a triangular pyramid-shaped pointed head 19 as shown in FIG. 18 bolt lower end portions 20 are inserted, and nuts 21 are fastened to the bolt lower end portions 17 and 20 from the back side of the base 2 to be fixed upright on the board surface of the base 2, that is, bolts are planted. The spike member is not limited to the above, and may be a spike member having a conical cusp. The length of the pointed head 16 of the spike member 15 and the pointed head 19 of the spike member 18 are pierced into the pneumatic tire wheel of the automobile (vehicle) that intends to break through the barricade 1 and forced by puncturing the pneumatic tire. In particular, the size is such that the automobile (vehicle) can be stopped. In addition, among the large number of through holes 4 that are dispersedly arranged on the outer side portions 14 and 14 on both sides of the wheel passage area on the surface of the board 3, an appropriately selected through hole 4 has a medium as shown in FIG. The pole member 23 having the actual cylindrical portion 24 is bolted by the same method as the method for fixing the spike members 15 and 18 described above. The length of the cylindrical portion 24 of these pole members 23 is slightly larger than the height of the bottom of the vehicle body of the automobile (vehicle), and hits the bottom of the automobile body where the barricade 1 is to be forced to break through. It is formed to break and force it to stop. Note that the pole member 23 is not planted in the intermediate portion 13 between the two wheel passage areas 11 that are parallel to each other, and a vehicle that is permitted to pass passes through both wheel passage areas 11 and 11. The vehicle can be safely passed without any damage to the vehicle.

  Bolts such as spike members 15, 18, pole members 23, etc. are not planted at all in the through-holes 4 existing in the two parallel wheel passage areas 11, 11 defined on the surface of the belt-like board 3. The blank state is set. It should be noted that some of the through holes 4 existing in both wheel traffic areas 11 and 11 are appropriately selected until immediately before the vehicle (vehicle) permitted to pass passes through both wheel traffic areas 11 and 11. Several spike members 15, 18 and bolt lower end portions 17, 20, 25 of the pole member 23 are inserted into the through-hole 4 (not shown), and are attached in an upright manner so that they can be pulled out without being bolted by the nut 21. Immediately before the vehicle (vehicle) permitted to pass passes through the wheel passing areas 11, 11, the spike members 15, 18 and the pole member 23 are extracted, and the vehicle allowed to pass passes through the both wheel passing areas 11, 11. 11 can be safely passed, and the forcible stop function of the automobile (vehicle) forcibly entering the barricade 1 can be sufficiently secured.
