Description

DETAILED DESCRIPTION OF THE INVENTION SUMMARY OF THE INVENTION A concrete block apparatus is described that is intended for use in end-to-end arrangements to create barriers, such as roads or parking lots.

The concrete block 1 has an elongated shape with a substantially triangular cross section with rounded side walls, and has a T-shaped metal piece 4,
Connected by 5. The T-shaped connecting piece is fixed to the end face of the block 1 when the block is cast, and is formed by providing horizontal bars 4'', 5''. The blocks 1 are connected by surrounding the two horizontal bars as described above with a tubular member 8 in an end-to-end position on the adjacent end surfaces of the two concrete blocks, and thereby fixedly connecting them. . The block can be provided with a device 31 for expanding its upper part and improving the block's ability to flexibly guide the vehicle onto the road. TECHNICAL BACKGROUND The present invention relates to a concrete block device that is connected end-to-end to define an enclosed area such as a road, parking lot, or the like.

This concrete block guides a car leaving the road back onto the normal road, minimizing possible damage to the car body and preventing the car from plunging into the roadway of oncoming traffic. The purpose is to The equipment used to connect concrete blocks of the type described above should be such that the blocks can be easily connected when placed in place and easily separated if necessary. This results in significant labor and expense savings.

To achieve these objects, the present invention provides a connecting member consisting of a generally T-shaped piece of metal installed at each end of the block and embedded in the block, the transverse bar of said T-shaped piece being embedded in the block. extending parallel to the relevant end faces of the concrete blocks, said crossbars are arranged in a connected manner so as to be surrounded by a tube with a similar crossbar of a connecting member fixed to the end faces of the adjacent concrete blocks, whereby the two It is characterized by combining and fixing blocks.

The connecting member in the present invention can be placed in a preferably semicircular notch formed approximately in the center of the end face of the concrete block.

According to another aspect of the invention, a connecting member of the type described above comprises:
It can also be located near the lower slope of the block, ie on the outer side of the block. In this case, the blocks can be substantially hollow, which makes it possible to suspend the concrete blocks on support rods. Many different suspension devices can be used for this purpose. Furthermore, the block can also be formed with only a single leg (side wall). In the latter case, the block is preferably fitted with a counterweight to ensure accurate positioning of the block. Additionally, according to another aspect of the invention, a single wall block can be formed as follows.

That is, a cutout can be provided in the suspended part, i.e. the top, of a single-wall block, into which a corresponding protrusion formed in the top of a similar single-wall block can be inserted, so that two single-wall blocks can be used to form block assemblies. It has been found that when a car hits a concrete block at a certain speed and angle of impact, the car often drives over the concrete block.

This risk is eliminated, albeit to a limited extent, by one aspect of the present invention. This embodiment features a circular rail intended to be attached to the top surface of a concrete block, which circular rail is softly rounded and enlarged at the top of the concrete block to prevent it from climbing over the sides of the concrete block. To improve the ability of concrete blocks to guide a car back to its normal driving path. These and additional features of the invention will be pointed out in the claims.

Hereinafter, the present invention will be described in more detail with reference to the accompanying drawings.

In the case of the groove 34, the circular rail 31 is simply slid at the end into the desired position, whereas in the case of the groove 35, the circular rail is placed over the holder 33 and then slid laterally to the desired position. position. The arms 36 of the holder 33 are designed to be elastically pressed against the inner surface of the circular rail so that the circular rail is fixed in a predetermined position on the upper surface of the concrete block 32. 14 and 15 each show a circular rail 31 and a concrete block 32 to be attached to each other.

Although FIG. 15 shows the groove 34 and the groove 35, when forming the circular rail 31 having the groove 35, the groove 34 and the groove 35 are shown.
Those skilled in the art will appreciate that the arm portion 36 of the holder 33 can be pressed against the inner surface of the circular rail 31 adjacent to the groove portion 35 by shaping the circular rail 31 to allow slight displacement. It should be obvious. Obviously, there is nothing to prevent designing the circular rail 31 as shown in Figure 15, if such a connection is desired. Figures 16 and 17 show the ends of the circular rails 31, which, as shown in these figures, are arranged in such a way as to prevent a motor vehicle attempting to drive onto the concrete blocks from hitting the edges. Biased and preferably asymmetrical.

In this regard, reference is made to the provision of an opening 37 corresponding to the cutout 38 in the end face of the concrete block 32, through which a rod supporting a traffic or road sign, for example, is accommodated and held. put. In this regard, it is also worth mentioning that the hollow circular rail 31 allows electrical wires and cables to be safely and protectedly extended inside it for road markings to be illuminated. In FIG. 18, a clamping member 39 is shown, which is made of sheet metal or plastic and is placed on the joint between two circular rails 31 installed in an end-to-end relationship. and is intended to be held in this position by its inherent elasticity. This tightening member 39 includes
A short pin 40 is provided in the opening 37, which is inserted, for example, by a clamping action. Finally, FIG. 19 shows a concrete block 3 with a shaft 41 supporting a roller 42 on its lower surface.
2, which facilitates movement of the block 32.

The circular rail does not have to have the same length as the concrete block 32, but since the circular rail 31 attached to the top surface of the block 32 provides a fixing effect, the block 32 is provided with the rollers 42 to facilitate its movement. In particular, they can be provided at unconnected locations. Conventional blocks had to be provided with legs so that, for example, a fork of a forklift could be inserted under the block to move the block. The circular rail 31 can, of course, adopt many other shapes than those illustrated, provided that it is prevented from driving over the concrete block and into the road on the opposite side of the block. shall be. Furthermore, the rails should have a shape that eliminates the tendency of the vehicle to sway and should guide the vehicle back onto the road quietly. Without going into detail, it will be apparent to those skilled in the art that various shapes of circular rails may serve this purpose. Furthermore, the circular rail 31 is preferably provided with openings 43 in which, for example, lighting lamps can be fitted. If desired, rubber pads could be inserted between the end faces of adjacent blocks. The present invention is not limited to the illustrated embodiments, and various modifications can be made within the scope of the present invention.
