(21) Refer to FIG. 2 and FIG. 4, the fixing plate 30 which is provided with a plurality of insertion holes 31 is connected to and arranged around the bottom end of the free standing casing tube 5. The bolts 13 of the mounting base 10 are inserted through the insertion holes 31 respectively. The fixing plate 30 can be connected with the free standing casing tube 5 by welding or other common ways.

(22) As shown in FIG. 2 and FIG. 4, the respective nuts 40 are threaded on the respective bolts 13 of the mounting base 10 correspondingly so as to thread and fasten the fixing plate 30 on an upper surface a2 of the floor a.

(23) As shown in FIG. 1 and FIG. 2, the rough-in assembly 100 further includes a decorative cover 50 which is movably mounted to an outer peripheral wall of the free-standing casing tube 5 and abutting against the upper surface a2 of the floor a. Thereby the fixing plate 30, the respective bolts 13 and the nuts 40 are covered by the decorative cover 50 for aesthetic purposes.

(24) In this embodiment, the bottom plate 11 is secured on an upper surface b1 of the laminated wood b by a plurality of fasteners 112, as shown in FIG. 4 and FIG. 5. The fastener 112 can be, but not limited to, a screw. Other ways of fastening the bottom plate 11 are also possible.

(25) Refer to FIG. 7, besides the two locking slots 121, the tube-fixing portion 12 further includes two vertical plate portions 122 opposite to each other, a horizontal plate portion 123 connected between the vertical plate portions 122, two vertical notches 124 and two horizontal notches 125. The locking slots 121 are spaced apart from each other and arranged at both the vertical plate portions 122 and the horizontal plate portion 123. A part of the locking slot 121 located at the vertical plate portion 122 forms the vertical notch 124 and a part of the locking slot 121 arranged at the horizontal plate portion 123 forms the horizontal notch 125 while the vertical notch 124 and the horizontal notch 125 are communicating with each other. As shown in FIG. 6, both the cold-water connection tube 21 and the hot-water connection tube 22 are bent tubes each of which includes a horizontal portion 201, a vertical portion 202, and a curved portion 203 located between the horizontal portion 201 and the vertical portion 202.

Thus the vertical portions 202 of both the cold-water connection tube 21 and the hot-water connection tube 22 are locked and positioned firmly in the two locking portions 126 after being laterally mounted into the locking slots 121 correspondingly. The design of the curved side and the locking portion 126 ensures that both the cold-water connection tube 21 and the hot-water connection tube 22 are positioned in the locking slots 121 more tightly. This also helps the following connection and fixing of the cold-water inlet tube 4a and the hot-water inlet tube 4b.

(27) As shown in FIG. 7 and FIG. 8, the vertical plate portion 122 of the tube-fixing portion 12 horizontally extends outward to form a connection plate 127 which is fixed on the upper surface 111 of the bottom plate 11 by welding or other common ways.

(28) In this embodiment, as shown in FIG. 5, each of the bolts 13 of the mounting base 10 is projecting from the upper surface of the connection plate 127. The bolt 13 can be directly fixed on the upper surface of the connection plate 127 by welding. Or after the bolt 13 being passed through and positioned by the connection plate 127, the connection plate 127 is fixed on the upper surface 111 of the bottom plate 11 so that the head of the bolt 13 is clipped between and fixed by the connection plate 127 and the upper surface 111 of the bottom plate 11.

(29) As shown in FIG. 2, FIG. 3 and FIG. 4, it should be noted that the laminated wood b is used in combination with two pads b2 so that the lower surface of the floor a will not be in direct contact with the laminated wood b. The two pads b2 are stacked vertically and arranged between the floor a and the laminated wood b. Thus the floor a and the laminated wood b are spaced apart from each other. Each of the pads b2 is provided with an opening b3 which is having a certain size for receiving the mounting base 10 therein and for control of the length of the bolt 13 projecting from the mounting hole a1 of the floor a. In other words, plumbers first measures the dimensions of the site where they are going to install the free-standing faucet 1 (such as the thickness of the floor a) and the size of the components related to the free-standing faucet 1 (such as the mounting position of the cold-water supply pipe 6a and the hot-water supply pipe 6b) in order to produce the laminated wood b and the pads b2 with required thickness. The number of the pads is not limited. The pads b2 can even be directly formed on the laminated wood b. Alternatively, the two pads b2 are integrated into one part. The design of the pad b2 are not limited as long as the mounting base 10 can be fixed on the laminated wood b tightly and the length requirements for the bolt 13 projecting from the mounting hole a1 of the floor a are met. It should be noted that the laminated wood b and the pads b2 mentioned above are prepared or produced by the workers with reference to the product instructions of the present invention, thus they are not a part of the present rough-in assembly 100.

(30) As shown in FIG. 2 and FIG. 4, in order to install the free-standing faucet 1 of the present invention, firstly the mounting base 10 is fastened to and fixed on the upper surface b1 of the laminated wood b prepared in advance. Then the cold-water connection tube 21 and the hot-water connection tube 22 of the connection tube set 20 are respectively horizontally mounted into the two locking slots 121 of the tube-fixing portion 12 and connected to the cold-water supply pipe 6a and the hot-water supply pipe 6b correspondingly. Next the two pads 2 are stacked over and under the laminated wood b so that the mounting base 10 is located in the respective openings b3. Then the respective bolts 13 are inserted through the respective mounting holes a1 on the floor a and extending upward after the floor a being covered on the assembly. Now the respective insertion holes 31 of the fixing plate 30 on the bottom of the free standing casing tube 5 are fitted to the respective bolts 13 while the cold-water outlet end 212 of the cold-water connection tube 21 and the hot-water outlet end 222 of the hot-water connection tube 22 are respectively connected to and communicating with the cold-water inlet tube 4a and the hot-water inlet tube 4b. Then the nuts 40 are respectively threaded onto the bolts 13 and tightened to install and fasten the free-standing faucet 1 on the mounting base 10 smoothly. Lastly, the fixing plate 30 is covered with the decorative cover 50 and the installation of the free-standing faucet 1 has been completed.

(31) Refer to FIG. 9, FIG. 10 and FIG. 11, another embodiment is disclosed. The difference between this embodiment of a rough-in assembly 101 and the above embodiment of the rough-in assembly 100 is in that: the rough-in assembly 101 is suitable for the cold-water supply pipe 6a and the hot-water supply pipe 6b arranged vertically while the rough-in assembly 100 is applied to the cold-water supply pipe 6a and the hot-water supply pipe 6b disposed horizontally. Thus the bottom plate 11 and the tube-fixing portion 12 of the mounting base 10 are a bit different from those of the above embodiment. More specifically, the bottom plate 11 of the mounting base 10 is fastened on the upper surface b1 of the laminated wood b and is provided with a through hole 113 that allows the cold-water connection tube 21 and the hot-water connection tube 22 of the connection tube set 20 to insert therethrough. Thus the connection tube set 20 is passed through the laminated wood b. As shown in FIG. 12, both the cold-water connection tube 21 and the hot-water connection tube 22 are straight tubes vertically inserted through the through hole 113 while those of the above embodiment are bent tubes. The tube-fixing portion 12 is a piece of plate provided with a plurality of positioning holes 128 and two openings that form the two locking slots 121. By the respective bolts 13 being inserted through and positioned in the respective positioning holes 128, the tube-fixing portion 12 (the piece of plate) can be abutting against and positioned on the upper surface 111 of the bottom plate 11.

(32) More specifically, as shown in FIG. 12 and FIG. 13, the locking slot 121 is a slotted hole having one side thereof as an insertion side 121a and the other side thereof as a locking side 121b. The width of the insertion side 121a is larger than that of the locking side 121b so that both the cold-water connection tube 21 and the hot-water connection tube 22 are able to be inserted through the insertion sides 121a and then horizontally sliding into the locking sides 121b correspondingly.

(33) A support circular flange 213 and a circular flange 223 are respectively formed on an outer peripheral wall of the cold-water connection tube 21 and an outer peripheral wall of the hot-water connection tube 22. The diameter of both the support circular flanges 213, 223 is between the width of the insertion side 121a and the width of the locking side 121b so that the wall surface of the support circular flange 213/223 is abutting against and supported by the upper surface at the locking side 121b of the piece of plate (the tube-fixing portion 12).

(34) Refer to FIG. 14 and FIG. 15, a further embodiment is disclosed. A rough-in assembly 102 of this embodiment and the rough-in assembly 101 of the above embodiment have similar structures. The difference between the rough-in assembly 102 and the above rough-in assembly 101 is in that: the bottom plate 11 is fastened on the lower surface b4 of the laminated wood b in this embodiment instead of being fastened on the upper surface b1 of the laminated wood b in the above embodiment. The respective bolts 13 extending upward from the upper surface of the upper surface 111 of the bottom plate 11 are passed through the laminated wood b and inserted through the respective positioning holes 128 of the tube-fixing portion 12 so that the tube-fixing portion 12 is abutting against and positioned on the upper surface 111 of the bottom plate 11. In order to make the bolts 13 pass through the laminated wood b smoothly, the laminated wood b is provided with a hole b5 which is formed or prepared in advance by the workers.

(35) The installation of the rough-in assembly 101 of the second embodiment and the rough-in assembly 102 of the third embodiment is mostly the same as that of the rough-in assembly 100 of the first embodiment. The difference between the installation of the second and the third embodiments and that of the first embodiment is in that: the cold-water connection tube 21 and the hot-water connection tube 22 of the second and the third embodiments are straight tubes which are inserted through the through hole 113 of the bottom plate 11 and the wider insertion side 121a of the respective locking slots 121 on the tube-fixing portion 12 firstly and then moved horizontally to be mounted and secured firmly at the locking side 121b with smaller width.

(36) In summary, the rough-in assembly 100, 101 or 102 of the present invention includes no passage in the mounting base so that there is no need to produce the base integrally by casting copper-based alloys. The rough-in assembly used in combination with only copper-based pipes has features of simple structure and easy production.

(37) Thus the production cost is dramatically reduced. Moreover, the bottom plate 11 of the rough-in assembly 100, 101 or 102 is directly disposed on the laminated wood b. The design puts most of the weight of the free-standing faucet 1 on the laminated wood b. The free-standing faucet 1 is secured more stably and firmly after installation compared with the prior arts because that the laminated wood b provides a larger contact surface. Thus the free-standing faucet 1 will not shake or move around while in contact with users' hands in use.

(38) Additional advantages and modifications will readily occur to those skilled in the art. Therefore, the invention in its broader aspects is not limited to the specific details, and representative devices shown and described herein. Accordingly, various modifications may be made without departing from the spirit or scope of the general inventive concept as defined by the appended claims and their equivalent.
