Description
- There is no cross-reference to related applications
- The present invention generally relates to curbs, especially to precast curbs and their installation.
- Curbs are border members having a vertical component used to separate a paved section such as a parking or a road from another section which may be, for example, a turf strip, a different area or a road. Usually, these curbs are cast in situ and the major part of the curb is under the ground to provide a high stability and resistance to collision. It also helps also to keep the curd in place notwithstanding the pressure applied by the pavement on one side and by the ground on the other side. A main disadvantage of the usual construction method is that curbs have to be cast in particular weather conditions because of the need for proper curing of the concrete. Furthermore, many highly paid specialised workers are needed for the different steps involved in the construction of an in situ concrete curb and there is nowadays a lack of such specialized workers.
- A first object of the present invention is to provide a curb which is precast.
- Another object of the present invention is to provide a precast curb system and method of installation that allows the curb to be removed after its installation without sustaining any damage and reused thereafter.
- A further object of the present invention is to provide a method of installation of a precast curb having at least the same resistance than cast in situ curbs.
- Other and further objects and advantages of the present invention will be obvious upon an understanding of the illustrative embodiments about to be described or will be indicated in the appended claims, and various advantages not referred to herein will occur to one skilled in the art upon employment of the invention in practice.
- The aforesaid and other objectives of the present invention are realized by generally providing a precast curb system, comprising a precast curb having a top, a bottom, a pair of lateral sides and two ends and a joint adapted to be placed between two adjacent precast curbs, the joint having means to constrain relative lateral and vertical movement between adjacent precast curbs.
- The curbs of the present invention are molded prior to their installation in a controlled environment. The curbs are made of concrete and, in a preferred embodiment, are steel reinforced with at least one steel rod. The curbs may be tapered to facilitate their removal from the mold or for aesthetic reasons.
- A first advantage of the present invention is that the precast curbs may be installed in almost any weather conditions. The curing of concrete needs particular environmental conditions and it is most difficult to have these conditions in certain regions, especially in winter and rainy conditions. Also, the method disclosed in the present document requires fewer steps than the usual method for constructing curbs cast in situ. Indeed, in the latter, the formwork has to be made first, reinforcing bars are installed, expansion joints are installed, the concrete is cast into the formworks, workers prepare the concrete (raping and vibrating) and finally the concrete is allowed to cure. Time is critical because the concrete has to be cast quickly otherwise it has to be discarded. Furthermore, the curing period lasts a number of days before the formwork is removed and the earthwork may be completed. The precast curbs of the present invention are manufactured in a controlled environment away from their installation site and are installed directly on the construction site.
- The present invention provides a method of installation of a plurality of precast curbs having a bottom and two ends comprising the following steps; placing a pair of joint, each joint having means to constrain relative lateral and vertical movement between adjacent precast curbs, each joint being placed on the ground at a predetermined distance from each other corresponding to the length of the curb to be installed, and placing each end of a precast curb on one of the joints.
- The joint is used to align adjacent precast curbs and to maintain their relative position. In a first embodiment, the joint is H-shaped; a first and a second vertical plates extend vertically from a horizontal plate. A third vertical plate extends between the lateral plates at the middle of the first and the second vertical plates and two spaces are created to receive an extremity of two adjacent precast curbs. The bottom of the precast curb rest on the horizontal plate.
- In another embodiment, the joint is also H-shaped and adapted to follow the shape of a precast curb which has a frustum section. The joint comprise a first plate and a second plate, their top extremities leaning toward each other and a third plate or other attachment means extending between the first and the second plate. The angle between the first plate and the second are at the same angle than the angle between the lateral sides of the precast curb. This joint provides a high stability between adjacent precast curbs.
- In still another embodiment, the precast curb has a groove along the longitudinal axis on the bottom, adapted to receive a joint. The corresponding joint is a horizontal plate from which a plate extends vertically, on the middle line of the horizontal plate. Two adjacent precast curbs are disposed on the joint, the third plate being received by the grooves of two adjacent precast curbs interconnected with the groove. It is to be noted that even if a precast curb is cut, the joints can still be used.
- The precast curb may also be made in various forms such as corners and T-shaped forms, for example. For driveways, the precast curb may have a lower part to be at the ground level on the road side to allow the passage of cars.
- To displace a precast curb, slots may be molded on the bottom of the precast curb allowing a lift truck or other similar equipment to lift the precast curb. It is also possible to mold two longitudinal recesses along the precast curb, allowing a grip to lift and displace the precast curb.
- The joint may be made from a variety of materials, as long as it can resist the local weather and the forces exerted by adjacent precast curbs. The joint may be made from, for example, certain type of plastics, composites or metal.
- It is to be noted that although the element composing the constraining means, or joints, have been described as plates in the present document, equivalents having a sufficient rigidity to support the relative movements of and between precast curbs may be used. These equivalents may be, for example, rods, grids, gratings or any other suitable devices.
- The features of the present invention which are believed to be novel are set forth with particularity in the appended claims.
- The above and other objects, features and advantages of the invention will become more readily apparent from the following description, reference being made to the accompanying drawings in which:
