[0031] Please see Figure 1-6 This utility model provides a technical solution:

[0032] An end formwork for a precast concrete channel, comprising:

[0033] Template unit 1 includes a bottom mold 11, a main side mold 12 disposed on the upper end of the bottom mold 11 near both sides, a main end mold 13 disposed on the upper end of the bottom mold 11 near both ends for forming a precast concrete channel side wall pouring trough with the main side mold 12 and the bottom mold 11, a top mold 15 disposed on the upper end of the main side mold 12 and located between adjacent precast concrete channel side wall pouring troughs, and a top end mold 14 disposed at both ends of the upper part of the main side mold 12 for forming a precast concrete channel bottom pouring trough with the main side mold 12 and the top end mold 15.

[0034] The locking unit 2 includes a first locking component 21 for locking the main body end mold 13 and the top end mold 14 to one end of the main body side mold 12, and a second locking component 22 for locking the top bottom mold 15 and the top end mold 14.

[0035] It should be noted that when pouring precast concrete channel sidewalls of different lengths, a bottom mold 11 of the corresponding length and a main side mold 12 fixedly connected to the upper end of the bottom mold 11 are selected. The main end mold 13 is locked to both ends of the main side mold 12 by the first locking component 21. The top end mold 14 is fastened to both ends of the main side mold 12 by the second locking component 22 and is located on the upper end of the main end mold 13. Then, a top bottom mold 15 of the corresponding length is selected and locked to the lower part of the top end mold 14 by the second locking component 22 and is located between the adjacent precast concrete channel sidewall pouring grooves. Finally, concrete is poured into the precast concrete channel sidewall pouring groove and the precast concrete channel bottom pouring groove. This allows for flexible selection of the corresponding template according to the different sizes of precast concrete, resulting in a high template reuse rate.

[0036] A sealing strip 16 is provided between the main end mold 13 and the main side mold 12, and between the top end mold 14 and the main side mold 12, to prevent concrete from leaking from the gap between the main end mold 13 and the main side mold 12, and between the top end mold 14 and the main side mold 12 during the pouring process.

[0037] As an improvement, such as Figure 1 As shown, the bottom mold 11 is provided in two sets, which are used to cooperate with the main side mold 12 and the main end mold 13 to simultaneously pour the two side walls corresponding to the precast concrete channel.

[0038] Furthermore, an arc-shaped rotating plate 131 is fixedly connected to the lower end of the main body end mold 13;

[0039] The bottom mold 11 has two fixed ends connected to limiting arc plates 111, which are used to support the bottom of the arc-shaped rotating plate 131. The bottom of the arc-shaped rotating plate 131 is rotated and placed in the arc-shaped groove reserved at the upper end of the limiting arc plate 111.

[0040] As an improvement, such as Figure 1 , Figure 3 As shown, the first locking assembly 21 includes:

[0041] The first cylindrical nut 211 is evenly spaced from top to bottom along the main body side mold 12 near both ends. The first cylindrical nut 211 is threaded with a first positioning pin 2111 near both sides. The side of the main body side mold 12 is fixedly connected with a first main body ear plate 121 corresponding to one end of one of the first positioning pins 2111. The side of the main body end mold 13 is fixedly connected with a second main body ear plate 132 corresponding to one end of the other first positioning pin 2111. The first positioning pin 2111 passes through the upper part of the first main body ear plate 121 and the second main body ear plate 132 to the lower part.

[0042] The first locking nut 212 is threaded to the outside of the first positioning pin 2111 and located below the first main body ear plate 121 and the second main body ear plate 132, and is used to lock the first positioning pin 2111 between the first main body ear plate 121 and the second main body ear plate 132.

[0043] Furthermore, such as Figure 2 , Figure 5 As shown, a first top ear plate 141 is fixedly connected to the side of the top end mold 14, and the first top ear plate 141 is located directly above the second main body ear plate 132.

[0044] The first top ear plate 141 and the first main body ear plate 121 are positioned by the first positioning pin 2111 and the first cylindrical nut 211.

[0045] Furthermore, such as Figure 5 As shown, the second locking assembly 22 includes:

[0046] The second cylindrical nut 221 is provided in multiple sets and distributed on the outside of the top end mold 14 and the top bottom mold 15. The second cylindrical nut 221 is threaded with second positioning pins 2211 near both sides inside. The top bottom mold 15 is fixedly connected to the outside of the third top ear plate 151, and the top end mold 14 is fixedly connected to the outside of the second top ear plate 142.

[0047] The second locking nut 222 is threaded to the end of the second positioning pin 2211 and located on the side of the second top ear plate 142 and the third top ear plate 151, for locking the second positioning pin 2211 between the second top ear plate 142 and the third top ear plate 151.

[0048] It should be added that the first positioning pin 2111 and the second positioning pin 2211 are respectively provided with threads that match the first locking nut 212 and the second locking nut 222 near their ends. The main body side mold 12 is fixedly connected to the bottom mold 11. The first cylindrical nut 211 is provided with a threaded hole 2112 inside that corresponds to the outer side of the first positioning pin 2111, so that when the first cylindrical nut 211 is rotated, the corresponding two sets of first positioning pins 2111 can extend and retract relative to the first cylindrical nut 211.

[0049] It should be noted that: in the specific implementation process of this utility model, if... Figure 1-4 As shown, when pouring precast concrete channel sidewalls of different lengths, a bottom mold 11 of corresponding length and a main side mold 12 fixedly connected to the upper end of the bottom mold 11 are selected. The arc-shaped rotating plate 131 at the lower end of the main end mold 13 is placed inside the limiting arc plate 111. Sealing strips 16 are installed at the openings at both ends of the main side mold 12. Then, the main end molds 13 corresponding to the openings at both ends of the main side mold 12 are rotated respectively, so that the main end molds 13 close the openings formed by the main side mold 12 and the bottom mold 11. Then, the first cylindrical nut 211 is used to close the openings. The ends of the two corresponding first positioning pins 2111 are respectively inserted into the first main body ear plate 121 and the second main body ear plate 132, and the first positioning pins 2111 are locked by the first locking nut 212. When the first cylindrical nut 211 is rotated, the first cylindrical nut 211 moves along the inside of the first cylindrical nut 211 through the threaded hole 2112 and the thread on the outside of the first positioning pin 2111, so that the main body end mold 13 abuts against the side opening of the main body side mold 12, forming a precast concrete channel side wall pouring groove.

[0050] Subsequently, the top end mold 14 is placed on top of the main body end mold 13. The ends of the two corresponding first positioning pins 2111 inside the first cylindrical nut 211 are inserted into the first top ear plate 141, and the other ends are inserted into the first main body ear plate 121 at the same height as the first top ear plate 141 and locked by the first locking nut 212. Rotating the first cylindrical nut 211 causes the first positioning pin 2111 to move along the inside of the first cylindrical nut 211 through the threaded hole 2112 and the threaded engagement with the outer side of the first positioning pin 2111. This allows the top end mold to... 14 is pressed against one side of the main body side mold 12. The top bottom mold 15 of the corresponding length is selected. The third top ear plate 151 and the second top ear plate 142 are locked by the second positioning pin 2211 in the second cylindrical nut 221. The top bottom mold 15 is fixed to the bottom of the top end mold 14 and located between the adjacent concrete channel side wall pouring grooves. Finally, concrete is poured into the precast concrete channel side wall pouring groove and the precast concrete channel bottom pouring groove. Thus, the template of the corresponding length can be flexibly selected according to the precast concrete of different lengths. The template has a high reuse rate and low production cost.

[0051] The locking principle of the second locking component 22 for the top end mold 14 and the top bottom mold 15 is the same as that of the first locking component 21, and will not be described again.

[0052] like Figure 1 , Figure 4-5 As shown, in addition, when pouring the bottom of precast concrete channels of different spans, the spacing between adjacent bottom molds 11 is first adjusted to the required span distance. After the main end mold 13 is locked to the main side mold 12 and forms a precast concrete channel side wall pouring groove with the bottom mold 11 using the first locking assembly 21, the top end mold 14, which is adapted to the span, is placed on the upper end of the main end mold 13 and fastened to one side of the main side mold 12 by the first positioning pin 2111 inside the first cylindrical nut 211. Then, the selected... Select the top bottom mold 15 corresponding to the span, and fasten it to the lower part of the top end mold 14 and between the adjacent precast concrete channel side wall pouring grooves through the second positioning pin 2211 inside the second cylindrical nut 221, forming the bottom pouring groove of the precast concrete channel corresponding to the required span. Finally, pour concrete into the precast concrete channel side wall pouring groove and the precast concrete channel bottom pouring groove, so that the bottom of the precast concrete channel with different spans can be flexibly adjusted, further improving the utilization rate and versatility of the template.
