[0027] In summary, the present application has the following beneficial technical effects:
[0028] The structure includes an outer formwork, an inner formwork, end formwork, reinforcing members, internal concrete tie rods, and external concrete tie rods. One end of the outer formwork is fitted onto the formwork block. The inner formwork is located inside the outer formwork, and the end formwork is located between the outer and inner formworks, forming a cavity that fits the formwork block. The reinforcing member abuts against the outer formwork on one side along the bridge width direction, and the reinforcing member has near-concrete holes and far-concrete holes along the direction from near to far from the formwork block. One end of the internal concrete tie rod is connected to the inner formwork, and the other end of the internal concrete tie rod sequentially passes through the through holes and near-concrete holes on the outer formwork and connects to the reinforcing member. One end of the external concrete tie rod is connected to the inner formwork, and the other end of the external concrete tie rod sequentially passes through the through holes and near-concrete holes on the outer formwork and connects to the reinforcing member.

The setting of the reinforcing member, inner and outer concrete tie rods can not only strengthen the connection between the outer and inner molds, thus reinforcing the outer mold and ensuring construction safety, but also ensure that only the inner concrete tie rods will come into contact with the concrete when the user pours concrete into the mold cavity. This will not only prevent the formation of too many holes that need to be repaired on the finished bridge, but also eliminate the need for the user to open many rows of through holes for tie rods along the length of the bridge between the outer and inner molds, thus facilitating the reuse of the outer and inner molds.

[0038] Specifically, the end of the reinforcing member 3 connected with the whole-molding tie rod 7 away from the whole-molding tie rod 7 can be welded on the outer mold 1.
[0039] Referring to Figure 3 , Figure 4 , Figure 5 and Figure 6In the second embodiment, the in-concrete tie rod 4 comprises a screw rod 41, a rotating sleeve 42, two telescopic blocks 43 and a transmission unit 44. The screw rod 41 is provided with external threads at both ends for screwing nuts. The reinforcing member 3 abuts against the nut screwed on one end of the screw rod 41. The rotating sleeve 42 is sleeved on the screw rod 41. Two dovetail grooves 421 are formed on the end of the rotating sleeve 42 away from the outer mold 1 in the direction approaching or away from the screw rod 41. The two dovetail grooves 421 are mirror-symmetrically centered on the central axis of the rotating sleeve 42. The bottom end of each telescopic block 43 is provided with a dovetail protrusion matched with the dovetail groove 421, and the telescopic block 43 is slidably connected with the dovetail groove 421 via the dovetail protrusion. The transmission unit 44 comprises a rotating column 441 and a driving gear 442. One end of the rotating column 441 is inserted into the inside of the end of the rotating sleeve 42 away from the reinforcing member 3 and is rotationally connected with the inner wall of the rotating sleeve 42. The other end of the rotating column 441 is connected with the rotating shaft of the driving gear 442. A handle 443 is further connected with the rotating shaft of the driving gear 442. A gear rack is provided on the telescopic block 43 along the length direction of the dovetail groove 421 and is engaged with the driving gear 442. The external threads at both ends of the screw rod 41 are opposite in rotation direction. A connecting screw hole is formed on the end of the rotating column 441 away from the driving gear 442 and is matched with the external thread of the end of the screw rod 41 away from the reinforcing member 3.
[0040] Taking the external thread on the end of the screw rod 41 close to the reinforcing member 3 as left-handed thread (counterclockwise rotation is rotated into the direction close to the reinforcing member 3, and clockwise rotation is rotated out of the direction away from the reinforcing member 3) as an example, the implementation principle of the second embodiment provided by the present application is as follows:
[0041] Since the user needs to screw the nut on one end of the screw rod 41 first when installing the in-concrete tie rod 4, and then sequentially passes the other end of the screw rod 41 through the far-concrete hole formed on the reinforcing member 3, the through hole formed on the outer mold 1, the PVC pipe 8 arranged between the outer mold 1 and the inner mold 2, and the through hole formed on the inner mold 2 into the inner mold 2, and finally installs the nut on the other end of the screw rod 41 inside the inner mold 2, the user needs someone to hold the reinforcing member 3 to ensure that the reinforcing member 3 does not fall off during the process of moving from the outside of the outer mold 1 to the inside of the inner mold 2, or the end of the reinforcing member 3 away from the far-concrete hole falls down around the out-concrete tie rod 5 under the condition that the out-concrete tie rod 5 has been fixed, which will cause the installation of the in-concrete tie rod 4 to fail;
[0042] The rotation sleeve 42 is arranged so that the user can first screw the nut on one end of the screw rod 41, then screw the other end of the screw rod 41 into the threaded hole of the rotating column 441 through the rotation sleeve 42, then insert the screw rod 41, the rotation sleeve 42 and the transmission unit 44 into the inner mold 2 together, then hold the rotation sleeve 42 and rotate the screw rod 41 clockwise, at this time the nut on the end of the screw rod 41 away from the rotating column 441 will be tightened in the direction away from the reinforcing member 3, and will not be loosened in the direction close to the reinforcing member 3, so that the user can drive the two telescopic blocks 43 away from each other and abut the reinforcing member 3, the outer mold 1 and the inner mold 2 between the telescopic blocks 43 and the nut of the screw rod 41, so as to preliminarily fix the reinforcing member 3, and then the user can directly move to the inside of the inner mold 2 without the help of others, hold the rotation sleeve 42 and the handle 443 and rotate the handle 443 counterclockwise to detach the rotation sleeve 42 and the transmission unit 44 from the end of the screw rod 41 away from the reinforcing member 3, and finally screw the nut on the end of the screw rod 41, so as to facilitate the user to install the screw rod 41.
[0043] The working principle of the hanging basket outer mold few pull rod formwork system of the present application in use is as follows:
[0044] The arrangement of the reinforcing member 3, the concrete inner counter-pull rod 4 and the concrete outer counter-pull rod 5 can not only strengthen the connection between the outer mold 1 and the inner mold 2, play a role in reinforcing the outer mold 1 and ensuring construction safety, but also make only the concrete inner counter-pull rod 4 contact the concrete when the user pours concrete into the mold cavity, so that too many holes that need to be repaired are not formed on the formed bridge, and the user does not need to open many rows of through holes for passing the pull rods along the length direction of the bridge between the outer mold 1 and the inner mold 2, so as to facilitate the reuse of the outer mold 1 and the inner mold 2.
[0045] It should be noted that the above are preferred embodiments of the present application, and do not limit the protection scope of the present application, therefore: any equivalent changes made according to the structure, shape, principle of the present application should be covered within the protection scope of the present application.
