Bollards are utilized in a myriad of applications, for one of several purposes. You need just to keep a sharp eye to see bollards around us every day. In parking lots, driveways, and drive-thru lanes, bollards are utilized to protect buildings, teller machines, utilities like gas meters, electrical equipment and fire hydrants, handicap parking signs, gate entry keypads, and to restrict access to undesired areas. In factories and warehouses, bollards are important for safeguarding pedestrians as well as guarding storage racks and capital equipment from fork truck collisions.
Other industries which locate a heavy usage of where to buy bollards include automated car wash facilities, self-storage facilities, gas stations and convenience stores, propane dispensing, and parking garages, amongst others.
Foundation mounted bollards are usually placed in one of two ways. The first, most inexpensive way, is to use a plate mounted bollard. These bollards are steel pipes welded to your flat steel plate that may be anchored to your hard surface using concrete anchors. This process of installation is fast and inexpensive, requiring the installer to drill four to eight holes in the concrete and bolt down the bollard with expansion or screw anchors.
The downside for this installation method, when used with a rigid bollard, is the fact that anchors are usually not sufficiently strong to withstand anything over a minor collision. The plate anchors often are pulled up and maybe the plate bends, leaving a post which leans and is not capable of properly serve its purpose. Plate mounted bollards often require constant maintenance and replacement.
The 2nd technique for installing bollards involves employing a longer steel pipe and burying a part of it deep in the ground. This technique affords the bollard a lot more strength than surface mounted, however it could be extremely expensive to put in in the event the surface is concrete and already poured. Installation in cases like this requires coring an opening within the surface using an expensive diamond bladed coring saw. These machines as well as their blades are costly and require water cooling, developing a mess during installation. When the concrete is cored as well as the bollard is at place, the hole has to be backfilled with concrete to secure the bollard. For additional strength, these bollards are frequently loaded with concrete, as well. Though the bollard pipe is comparatively cheap, this installation strategy is costly and time-consuming.
Although very strong, you can find significant disadvantages to core installations. Above all, there is no share with this technique upon impact. Though desired in high security applications, any vehicle impacting this kind of bollard is going to be significantly damaged and its passengers in danger of injury. Loads carried by fork trucks can also be thrown due to the jarring impact likely to occur. Further, the bollard or its foundation could be damaged by such an impact, again leaving a tilted and fewer effective barrier requiring costly maintenance to improve. Often the steel bollard itself is beyond repair and should get replaced with an entirely new bollard.
Another disadvantage of this kind of installation is it is a permanent installation with little flexibility for movement. In factory applications, tools are often moved and rearranged. Bollards utilized to protect equipment or storage racks which are core-installed are certainly not easily moved. The concrete surrounding the bollard must be broken out and also the large remaining hole filled, leaving a factory floor packed with unsightly patches. If the bollard itself is reusable after removal, the whole expensive installation process is started over on the new location.
Some designs happen to be developed to make an effort to solve these issues through the use of plastic or spring loaded bollards, however these designs are afflicted by too little strength. If the plastic is of insufficient stiffness, the entire function of access denial is lost. On the other hand, very stiff plastic designs have gotten difficulty with long-term durability. Minor collisions often wear away at such devices, and then in outdoor applications UV degradation turns into a concern.
Designed and patented in Europe by Belgian inventor Gerard Wolters is really a unique system which solves many of the problems related to traditional foundation mounted bollards. In other words, the system uses a compressed rubber base to act being an energy absorbing mass. This elastomer allows the bollard to tilt slightly when impacted, in all the different 20 degrees from vertical, then return upright while still stopping the colliding vehicle.
This method is mounted on concrete using concrete anchor screws. These anchors affix the base component over the adapter, which pre-compresses the elastomer against the ground. The base and adapter pieces are created from a special ductile cast iron, making the pieces less brittle than typical cast iron, and has a very low (-40 degrees) brittleness temperature. The steel pipe which functions as the bollard post is a typical steel pipe inserted in to the adapter. Standard pipe is utilized to give the final user the flexibility to weld fencing using standard components if required. Concrete fill is not needed within the bollard pipe, though is permitted. In fact, sign posts could be inserted to the post and concrete completed place.
Upon collision, the pipe and adapter can tilt inside the base, forcing the adapter to help compress the elastomer toward the impact. The elastomer absorbs most of the vitality of the impact and lengthens the deceleration duration of the automobile. The elastomer is of sufficient strength to then rebound, usually pushing the car away from the bollard and going back to a vertical position. The tilt of the pipe has limitations to approximately 20 degrees after which the bollard will become rigid.
Bollards are designed in a selection of sizes, every one of that is appropriate for various expected collision speeds and masses. Further, modular connectors which may be used to create fencing and guards away from multiple base units have already been created to eliminate welding. By using multiple base units, the greatest strength from the rebounding bollard unit can be increased.
These new bollards make use of the much simpler way of surface installation, greatly reducing installation costs, while maintaining the flexibleness to move bollards as conditions warrant. This can be accomplished minus the normal disadvantage of insufficient strength, since the elastomer within the bollard system greatly reduces the maximum impact forces put on the base anchors. This is because deceleration of your impacting vehicle is much less severe than during an impact using a rigid bollard. Energy is transferred to the elastomer as opposed to straight to a rigid post, reducing the harsh impact of the relatively immovable object.
This leads straight to the most significant benefits of the brand new bollard system and that is certainly the lowering of injury to both offending vehicles and to the bollard system itself. Direct damage to vehicles is reduced because of the reduction of peak impact force seen through the vehicle. This will not only avoid injury to the car, but the chance of trouble for a passenger is likewise reduced. With regards to a fork lift in a factory or warehouse, the possibility of a thrown load can also be reduced, avoiding the chance of bystander injury and stock loss.
Finally, damage to the bollard as well as its foundation is reduced. Because the post is constructed of strong steel pipe, it maintains its strength, but because of its forgiving nature, much less force is transferred to the building blocks. This simplifies and eliminates maintenance while preserving an great looking facility.
These bollards should be placed on concrete, as an asphalt surface is not really of adequate strength to anchor the bollard system. Taking into consideration the replacement costs of damaged bollards, however, it could be affordable to pour a concrete pad and eliminate years of costly maintenance and asphalt repair. As mentioned before, each bollard is sized for expected loads with regards to mass and speed. Should that limitation be exceeded, it really is possible to break a part of the device. Most likely that concerns the post, adapter, or base. Fortunately, the system is modular and easily repaired. Posts could be replaced by loosening several set-screws, wwbpkl and replacing, and re-tightening the set screws. Adapter and Base components may be replaced by carefully eliminating the concrete screw anchors and replacing the component.
The SlowStop Bollard product is a progressive cool product which solves lots of the problems involved with bollard collisions along with installation and maintenance issues. Injury to vehicles, passengers, vehicle loads, and the removable bollards with locks themselves is cut down tremendously due to the absorption of impact energy by an elastomer hidden inside the base of the bollard. This elastomer allows the bollard to tilt when impacted and return upright afterward. SlowStop Bollards are quick and inexpensive to set up, flexible because they are easily moved, and simple to keep if there is the need. Safety fencing and barriers are easily created using modular connectors, avoiding the necessity to weld pipe together.
