Bollard – Maybe You’ve Asked Yourself The Reasons You Might Need This..

Posted on January 29, 2019 in Womens Clothing

Bollards are used in a number of applications, for one of several purposes. You need just to keep a sharp eye to view bollards around us every day. In parking lots, driveways, and drive-thru lanes, bollards are used 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 very important for protecting pedestrians in addition to guarding storage racks and capital equipment from fork truck collisions.

Other industries which locate a heavy use of steel security bollards include automated car wash facilities, self-storage facilities, gas stations and convenience stores, propane dispensing, and parking garages, among others.

Foundation mounted bollards are typically installed in certainly one of two ways. The initial, most inexpensive way, is to use a plate mounted bollard. These bollards are steel pipes welded to your flat steel plate that can 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 inside the concrete and bolt on the bollard with expansion or screw anchors.

The down-side for this installation method, when used in combination with a rigid bollard, is the fact that anchors are usually not sufficiently strong to stand up to anything over a minor collision. The plate anchors often are pulled up and maybe the plate bends, leaving a post which leans and is no longer capable of properly serve its purpose. Plate mounted bollards often require constant maintenance and replacement.

The next technique for installing bollards involves utilizing a longer steel pipe and burying a part from it deep in the earth. This technique affords the bollard a lot more strength than surface mounted, however it may be very costly to set up if the surface is concrete and already poured. Installation in this case requires coring an opening in the surface utilizing an expensive diamond bladed coring saw. These machines along with their blades are costly and require water cooling, developing a mess during installation. After the concrete is cored as well as the bollard is at place, the hole should be backfilled with concrete to secure the bollard. For additional strength, these bollards are frequently filled with concrete, too. Even though the bollard pipe itself is relatively inexpensive, this installation technique is costly and time-consuming.

Although quite strong, there are significant disadvantages to core installations. Most significantly, there is no give this technique upon impact. Though desired in high security applications, any vehicle impacting this kind of bollard is going to be significantly damaged as well as its passengers in danger of injury. Loads carried by fork trucks may also be thrown because of the jarring impact likely to occur. Further, the bollard or its foundation can be damaged by this type of impact, again leaving a tilted and fewer effective barrier requiring costly maintenance to improve. Usually the steel bollard is beyond repair and must be replaced with an entirely new bollard.

Another downside of this type of installation is that it is a permanent installation with little flexibility for movement. In factory applications, equipment is often moved and rearranged. Bollards utilized to protect equipment or storage racks which are core-installed usually are not easily moved. The concrete surrounding the bollard has to be broken out and also the large remaining hole filled, leaving a factory floor packed with unsightly patches. If the bollard is reusable after removal, the entire expensive installation process begins over at the new location.

Some designs have been developed to make an effort to solve these complications with the use of plastic or spring loaded bollards, however these designs have problems with an absence of strength. In the event the plastic is of insufficient stiffness, the complete purpose of access denial is lost. On the other hand, very stiff plastic designs have had difficulty with long lasting durability. Minor collisions often wear away at such devices, and in outdoor applications UV degradation turns into a concern.

Designed and patented in Europe by Belgian inventor Gerard Wolters is a unique system which solves most of the problems related to traditional foundation mounted bollards. In other words, the device uses a compressed rubber base to behave 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 technique is connected to concrete using concrete anchor screws. These anchors affix the base component on the adapter, which pre-compresses the elastomer from the ground. The base and adapter pieces are made from a unique ductile cast iron, making the pieces less brittle than typical cast iron, and also has a very low (-40 degrees) brittleness temperature. The steel pipe which functions as the bollard post is actually a typical steel pipe inserted into the adapter. Standard pipe can be used to provide the final user the flexibleness to weld fencing using standard components if necessary. Concrete fill is not required inside the bollard pipe, though is permitted. In reality, sign posts can be inserted to the post and concrete completed place.

Upon collision, the pipe and adapter are permitted to tilt within the base, forcing the adapter to help compress the elastomer in the direction of the impact. The elastomer absorbs a lot of the power in the impact and lengthens the deceleration time of the vehicle. The elastomer is of sufficient strength to then rebound, usually pushing the automobile from the bollard and going back to a vertical position. The tilt of the pipe is restricted to approximately 20 degrees after which the bollard will become rigid.

Bollards are created in a selection of sizes, each of which can be suitable for various expected collision speeds and masses. Further, modular connectors which can be used to create fencing and guards from multiple base units have already been designed to eliminate welding. By making use of multiple base units, the ultimate strength in the rebounding bollard unit could be increased.

These new bollards utilize the more simple approach to surface installation, greatly reducing installation costs, while keeping the flexibleness to move bollards as conditions warrant. This is accomplished with no normal disadvantage of lack of strength, since the elastomer in the bollard system greatly cuts down on the maximum impact forces placed on the base anchors. The reason being deceleration of the impacting vehicle is far less severe than throughout an impact with a rigid bollard. Energy is transferred to the elastomer instead of directly to a rigid post, decreasing the harsh impact of a relatively immovable object.

This leads straight to the most important benefits of the brand new bollard system and that is certainly the reduction of injury to both offending vehicles and also to the bollard system itself. Direct harm to vehicles is reduced because of the reduction of peak impact force seen by the vehicle. It will not only avoid harm to the car, but the possibility of trouble for a passenger is likewise reduced. When it comes to a fork lift in a factory or warehouse, the possibility of a thrown load is also reduced, avoiding the potential for bystander injury and stock loss.

Finally, injury 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 foundation. This simplifies and eliminates maintenance while preserving an attractive facility.

These bollards must be placed on concrete, as an asphalt surface is not really of adequate strength to anchor the bollard system. Considering the replacement costs of damaged bollards, however, it could be cost effective to pour a concrete pad and eliminate numerous years of costly maintenance and asphalt repair. As earlier mentioned, each bollard is sized for expected loads with regards to mass and speed. Should that limitation be exceeded, it is easy to break a component of the program. Most likely that concerns the post, adapter, or base. Fortunately, the device is modular and simply 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 removing the concrete screw anchors and replacing the component.

The SlowStop Bollard product is a revolutionary 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 stainless steel bollards themselves is greatly reduced as a result of absorption of impact energy by an elastomer hidden inside the bottom of the bollard. This elastomer allows the bollard to tilt when impacted and return upright afterward. SlowStop Bollards are quick and inexpensive to install, flexible since they are easily moved, and simple to maintain if there is the necessity. Safety fencing and barriers are easily created using modular connectors, avoiding the need to weld pipe together.
