Description
Fle number: 11187 - 001 Revision: 5 Date: 2006/12/14 Title of the Invention [0001] Precast Curb System and Method of Installation thereof Cross-Reference to Related Applications [0002] There is no cross-reference to related applications Field of the Invention [0003] The present invention generally relates to curbs, especially to precast curbs and their installation.
Background of the Invention [0004] 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 paidspecialised 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.
Objects of the Invention [0005] A first object of the present invention is to provide a curb which is precast.
File number: 11187 - 001 Revision: 5 Date: 2006/12/14 [0006] 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.

File number: 11187 - 001 Revision: 5 Date: 2006/12/14 [0006] 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.
[0007] 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.
[0008] 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.
Summary of the Invention [0009] A precast curb system and method of installation thereof, comprising a precast curb having an elongated shape, an underneath surface, the elongated shape being limited by two vertical surfaces, and a joint having means to constrain lateral and vertical movement of the precast curb, the joint being adapted to receive two adjacent precast curbs.
Summary of the Invention [0009] A precast curb system and method of installation thereof, comprising a precast curb having an elongated shape, an underneath surface, the elongated shape being limited by two vertical surfaces, and a joint having means to constrain lateral and vertical movement of the precast curb, the joint being adapted to receive two adjacent precast curbs.
[0010] The curbs of the present invention are molded prior to their installation in a controlled environment. The curbs are made of concrete and, in the 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.
[0011] 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 present method 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 F'ile number: 11187 - 001 Revision: 5 Date: 2006/12/14 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.
[0012] 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. A 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 underneath surface of the precast curb rest on the horizontal plate.
[0013] In another embodiment, the precast curb has a groove along the longitudinal axis on the underneath surface, 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 interconnected with the groove. It is to be noted that even if a precast curb is cut, the joints can still be used.
[0014] 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.
[0015] The features of the present invention which are believed to be novel are set forth with particularity in the appended claims.

Although the invention is described in terms of specific illustrative embodiments, it is to be understood that the embodiments described herein are by way of example only and that the scope of the invention is not intended to be limited thereby.
Detailed Description of the Preferred Embodiment [0028] A novel precast curb system and method of installation thereof will be described hereinafter. Although the invention is described in terms of specific illustrative embodiments, it is to be understood that the embodiments described herein are by way of example only and that the scope of the invention is not intended to be limited thereby.
[0029] Figure 1 shows a first embodiment of a precast curb 100 which has an underneath surface 110, lateral sides 130 and a steel rod 120.
[0030] Figure 2 shows a first embodiment of a joint 200 which may be used with the precast curb 100 of the Figure 1. The joint has a horizontal plate 240 and a first and a second vertical plates 220 and 225 fixed at the lateral edges of the horizontal plate 240. A
third vertical plate 230 extends between the middle of the first and the second vertical plates 220 and 225. This configuration of the plates defines two spaces 210 and 211.
third vertical plate 230 extends between the middle of the first and the second vertical plates 220 and 225. This configuration of the plates defines two spaces 210 and 211.
[0031] To install the precast curb 100 in situ, two joints 200 are disposed on the ground, which has been preferably prepared as usual for a curb (except that no formwork or in situ casting of concrete is necessary), at a distance corresponding to the length of a precast curb 100. The extremities of the precast curbs 100 and 101 are inserted in the spaces 210 and 211 of the joint 200, as shown in Figure 3. Thus, the lateral surfaces 130 of a precast curb 100 are comprise between the first and the second vertical surfaces 220 and 225 and the underneath surface 110 rests on the horizontal plate 240.
[0032] In Figure 4, a second embodiment of the precast curb 300 is shown. The precast curb 300 has an underneath surface 310 and a longitudinal groove 320 on the underneath File number: 11187 - 001 Revision: 5 Date: 2006/12/14 surface 310 of the precast curb 300. A second embodiment of a joint 400 is shown in Figure 5, and is adapted to receive the precast curb 300 of Figure 4. The joint 400 has a horizontal plate 410 and a vertical plate 420. The installation of the precast curb 300 is similar to the method described before. The joint 400 is disposed on the ground, preferably prepared as usual for a curb, at a distance corresponding approximately to the length of a precast curb 300. The joint 400 is inserted in two consecutive precast curbs 300 and 301 as shown in Figure 6.
[0033] Figure 7a shows a starting element used to begin the course of the curb with a slope 710 going up gradually to the level 720 of a precast curb. Figure 7b shows an element creating a passage 760 for vehicles which is preferably at the ground level. As for the starting element, the slope 770 goes up gradually to the level 780 of a precast curb.
[0034] To facilitate the handling of the precast curb, two slots 810 may be molded, as shown in Figure 8 to allow a standard lift truck to manipulate them.
[0035] Figures 9a, b and c show the elements used for corners (9a and 9b) and for subdivision (9c). As seen in 9a and 9b, a corner may have an arcuate form 920 or right angle form 910.
[0036] The preparation of the ground similar to that of curbs cast in situ. An example is detailed in Figure 10. On one side of the precast curb 990, the top layer is turf 950, followed by a layer of top soil 955 and a layer of fill 960. These layers and the precast curb 990 are disposed on layer of fil1965. On the paved side, there is the paving 970 on a layer of fill 975 which are disposed on the soi1980.
[0037] In Figure 11, another embodiment for the precast curb is shown. This precast curb may be used in the same way than the first embodiment for the installation, the joints, the starting element, the driveway element, the slots for the manipulation, the corners elements and the subdivision elements.
