1. Field
The present application relates to concrete barriers. More specifically, the present application is directed to a connector and connection system to provide improved connection for various peripheral devices to the concrete barriers.
2. Brief Discussion of Related Art
A variety of modular concrete barrier systems (e.g., Jersey barrier systems) have been employed to separate lanes of traffic, re-route traffic especially during construction, provide crowd control at various events, as well as other applications. These systems are commonly used for temporary and in some cases semi-permanent applications.
One type of a modular concrete system is known as a J-J hooks concrete barrier system, which includes a plurality of concrete barriers. Adjacent concrete barriers lock with respect to one another using J-type connectors (hooks) disposed along the sidewalls of the concrete barriers. The J-J hooks concrete barrier system provides a self-aligning, easily modifiable and/or removable system. Specifically, an independent concrete barrier can be removed without disturbing the concrete barriers adjacent to that concrete barrier. Moreover, the barriers can be easily moved/adjusted in a desired direction.
The industry currently uses costly methods to attach various peripheral devices (e.g., lighting, fencing, and signage) to the concrete barriers. Generally, the barriers are drilled to attach saddle-mounted units for lighting, fencing, signage, and/or applications. On average, at least four (4) anchors (e.g., bolts) are required to attach the saddle of the unit to the concrete barrier. Moreover, two (2) mechanics are required to attach and/or remove each unit.
It is therefore desirable to provide a connector and connection system to provide improved connection for various peripheral devices to the concrete barriers, reducing costs associated with their attachment and removal.
In accordance with an embodiment, there is disclosed a connector to slip-fit into a gap between concrete barriers having a lock that engages the concrete barriers. The connector includes a saddle member and a fork member.
The saddle member includes a base to be disposed over the gap and partially atop the concrete barriers. The fork member extends below the base of the saddle member. The fork member includes an elongated base and legs that extend below the elongated base. The legs are to straddle the lock that engages the concrete barriers.
In accordance with another embodiment, a connection system is disclosed. The connection system includes at least a connector to slip-fit into a gap between concrete barriers having a lock that engages the concrete barriers.
Similarly, the saddle member includes a base to be disposed over the gap and partially atop the concrete barriers. The fork member extends below the base of the saddle member. The fork member includes an elongated base and legs that extend below the elongated base. The legs are to straddle the lock that engages the concrete barriers.
The connection system can also include a peripheral device that is connectable to the connector. The peripheral device includes an extension pole and a device. The device extends in relation to the extension pole. The device can be a fence device, a sign device and a light device.
These and other purposes, goals and advantages of the present application will become apparent from the following detailed description of example embodiments read in connection with the accompanying drawings.
Some embodiments are illustrated by way of example and not limitation in the figures of the accompanying drawings in which:
A connector and a connection system to provide improved connection for various peripheral devices to the concrete barriers are disclosed herein. In the following description, for the purposes of explanation, numerous specific details are set forth in order to provide a thorough understanding of example embodiments. It will be evident, however, to one skilled in the art, that an example embodiment may be practiced without all of the disclosed specific details.
Each pair of concrete barriers 102, 104 includes a lock 106 and slots 112, 114 along the sidewalls. The lock 106 removeably secures the barriers 102, 104 in relation to one another. The lock 106 includes reciprocally positioned J-type connectors (hooks) 108, 110 disposed along the sidewalls of the concrete barriers 102, 104. Reciprocal connectors 108, 110 can engage one another to secure the concrete barrier 102 in relation to the concrete barrier 104.
The slots 112, 114 extend along the sidewalls of the concrete barriers 102, 104 such that the concrete barriers 102, 104 can be disposed abutting one another, in which case the reciprocal connectors 108, 110 are inserted at least partially into the slots 112, 114. When the reciprocal connectors 108, 110 are engaged, a gap 116 is defined between the concrete barriers 102, 104 and the slots 112, 114.
The connector 200 is provided with a slip-fit connection that slides into the gap 116 (cross-like gap) created by the barriers 102, 104 of the system 100. The connector 200 includes a saddle member 202 and a fork member 204. The connector 200 can be cast in one piece, or can be cast in several pieces that are welded together at seams 206, 208, for example. The saddle member 202 is described in greater detail with reference to
At this point it is sufficient to mention that—as the connector 200 is slip-fit into the gap 116—the saddle member 202 is disposed over the gap 116 and partially atop each of the concrete barriers 102, 104. Moreover, the fork member 204 slides into the gap 116 and is disposed atop the lock 106 and straddles the lock 106 (e.g., reciprocal connectors 108, 110). This provides a simple yet rugged and durable connection to the concrete barriers 102, 104 of the system 100.
The base plate 302 is configured to be disposed over the gap 116 and partially atop each of the concrete barriers 102, 104. The peripheral plates 304, 306 extend below the base plate 302 and are configured to extend at least partially along the front and back walls of the concrete barriers 102, 104.
As illustrated, the peripheral plates 304, 306 are angled with respect to one another and outwardly from the base plate 302 to accommodate the sloping configuration of the front and back walls of the concrete barriers 102, 104 over which the saddle member 202 is disposed. The angulation of the peripheral plates 304, 306 can be adjusted depending on the configuration of the front and back walls of the concrete barriers 102, 104. For example, the peripheral plates 304, 306 can be parallel for certain configurations of the concrete barriers 102, 104 where the front and back walls of the concrete barriers 102, 104 are parallel.
The connector sleeve 308 is configured to connect to extension poles for various peripheral devices, e.g., lighting, fencing, and signage. Examples of these peripheral devices are described in greater detail with reference to
The base 402 includes an elongated top 404, bottom 410, and sloping sides 406, 408. The elongated top 404 and bottom 410 can be planar. The angulation of the sides 406, 408 with respect to the elongated top 404 of the fork member 204 matches the configuration of the peripheral plates 304, 306 with respect to the base plate 302 of the saddle member 202.
The flanges 412, 414 extend transversely to the elongated top 404 and bottom 410 of the base 402. The flanges 412, 414 are sized and dimensioned to extend into the slots 112, 114 of the concrete barriers 102, 104. The top and bottom of the flanges 412, 414 can be co-planar with respect to the top 404 and bottom 410, respectively. The bottom 410 of the base 402 and the bottoms of the flanges 412, 414 can thus be disposed in a planar configuration atop the lock 106. The configuration of the bottom 410 and the bottoms of the flanges 412, 414 can be adjusted with respect to a different lock between the concrete barriers 102, 104.
The legs 416, 418 extend below the base 402 and are to be disposed along the height of the gap 116. For example, the length of the legs 416, 418 can approximate the height from the bottom of the concrete barriers 102, 104 up to the top of the lock 106, such that the legs can straddle the lock 106.
As illustrated in
Examples of these peripheral devices are described in greater detail with reference to
The connector 200 is slip-fit into the gap 116. Accordingly, the saddle member 202 is disposed over the gap 116 and partially atop each of the concrete barriers 102, 104. The fork member 204 slides into the gap 116 and straddles the lock 106. This provides a simple yet rugged and durable connection to the concrete barriers 102, 104 of the system 100.
Specifically, the flanges 412, 414 extend into the slots 112, 114 of the concrete barriers 102, 104. The bottom 410 of the base 402 and bottoms of the flanges 412, 414 are thus disposed in a planar configuration atop the lock 106.
The extension pole 704 is sized and dimensioned to fit into the connector sleeve 308 or over a connector rod (not shown). One or more connectors 710, 712 (e.g., bolts) engage the extension pole 704 to secure the extension pole 704 in relation to the connector sleeve 308. Similarly, the extension pole 704 can fit over the connector rod and be secured by the one or more connectors 710, 712. Extension poles of different heights can be provided for various lighting applications, as indicated by the diagonal lines along the height of extension pole 704.
The lighting fixture 706 is secured or mounted to the extension pole 704. For example, the lighting fixture 706 is welded 708 to the extension pole 704. Various other connections of the lighting fixture 706 to the extension pole 704 can be provided.
The extension poles 804, 806 are sized and dimensioned to fit over the connector rods or into the connector sleeves 308 of respective connectors 200, which can be disposed in several gaps 116 formed between pairs of concrete barriers, one of which pairs (concrete barriers 102, 104) is illustrated in
The fencing 808 can be attached to the extension poles 804, 806 in a conventional or yet to be developed manner. Moreover, the fencing 808 can be replaced with a canopy (not shown), which can be provided over rows of concrete barriers.
The extension pole 904 is sized and dimensioned to fit over the connector rod or into the connector sleeve 308. One or more connectors 910 (e.g., bolts) engage the extension pole 904 to secure the extension pole 904 in relation to the connector rod or the connector sleeve 308. Poles of different heights can be provided for various signage applications, as indicated by the diagonal lines along the height of extension pole 904.
The sign 906 is secured or mounted to the extension pole 904. For example, the sign can be welded 908 to the extension pole 904. Various other connections of the sign 906 to the extension pole 904 can be provided.
It should be noted that one or more peripheral devices, such as lighting devices 702, fencing devices 802, and signage devices 902, or other peripheral devices, can be provided in various combinations along the concrete barrier system 100, which includes a multiplicity of concrete barriers and to which the peripheral devices can be connected using connectors 200.
