[0022] The utility model will be described clearly and completely in the following with the drawings and examples:

[0023] As Figures 1 to 3 The utility model discloses a template structure for open caisson construction, including a plurality of standard section templates 1, the standard section template 1 adopts the steel sheet to make, and this embodiment can be used for the production of square open caisson, also can be used for the production of circular open caisson, wherein when being used for producing square open caisson, the improvement of the application is mainly used at the side wall of open caisson, and the adjacent standard section template 1 between the corner of open caisson does not adopt the connecting mode of the following convex block 2 recess 3, directly carries out the conventional contact connection, then sets up the strengthening measure of the cable-stayed seat of prior art commonly used on the standard section template 1 on both sides of the corner and tightens high-strength screw.

[0024] The embodiment takes the construction of a circular caisson as an example, one end of the standard segmental formwork 1 protrudes and is provided with a connecting protrusion 2, and the other end is recessed to form a groove 3 structure; when two adjacent standard segmental formworks 1 are connected, the protrusion 2 is located in the groove 3; wherein the groove 3 is provided with a positioning plate 4 which can be adjusted in the width direction of the standard segmental formwork 1, and the sum of the lengths of the positioning plate 4 and the protrusion 2 in the width direction of the standard segmental formwork 1 is less than the length of the groove 3 in the same direction, so as to provide a moving space for the positioning plate 4 and facilitate the installation of the protrusion 2, which only needs to be horizontally connected with the adjacent two standard segmental formworks 1, without the need for insertion from top to bottom, thereby reducing the difficulty of installation and disassembly.

[0025] It is worth noting that since all formworks need to be closed to form a circular structure during the construction of the circular caisson, the last standard segmental formwork 1 needs to be hoisted and inserted, and only one standard segmental formwork 1 needs to be hoisted during disassembly, but this does not affect the convenient operation of the horizontal connection between the remaining standard segmental formworks 1, reduces the number of hoisting frequency, to a certain extent, reduces the complexity of operation, and also reduces the safety hazard. In addition, the structure of the formwork in the embodiment is used as a reference, since the inner and outer two sets of formworks need to be arranged coaxially during the construction of the caisson, the structure of the inner formwork is only needed to be adjusted by moving the structure features of the outer side protruding part of the standard segmental formwork 1 to the position of the inner side. Figure 2 Further, the structure of the standard segmental formwork 1 is adjusted by moving the structure features of the outer side protruding part to the position of the inner side.

[0026] Further, the structure of the standard segmental formwork 1 is adjusted by moving the structure features of the outer side protruding part to the position of the inner side.

[0027] As shown in FIG. 1, the standard segmental formwork 1 is provided with a protrusion 2 at one end thereof in the length direction, and a groove 3 at the other end thereof in the length direction. Figure 3 As shown in FIG. 1, the standard segmental formwork 1 is provided with a protrusion 2 at one end thereof in the length direction, and a groove 3 at the other end thereof in the length direction. Figure 3The example driving slope 11 gradually increases in slope from the end close to the protrusion 5 to the end away from the protrusion 5; in the working state, the two driving slopes 11 abut to realize positioning abutment of the positioning plate 4, so that the positioning plate 4 is closely attached to the protrusion 2, the tightness of the contact between the protrusion 2 and the inner wall of one side of the groove 3 is enhanced, and the tightness of the connection between the two standard segment templates 1 is further improved. In the initial state, the first positioning part 9 is located away from the protrusion 5, when the nut 7 moves along the axis of the bolt 6, the support sleeve 8 moves synchronously, thereby moving the first positioning part 9, the driving slope 11 on the first positioning part 9 contacts and pushes the driving slope 11 on the second positioning part 10 to move along the axis direction of the second positioning part 10, thereby pushing the positioning plate 4 to closely abut against the protrusion 2, as the nut 7 is screwed into place, the positioning plate 4 and the protrusion 2 realize complete close contact, ensuring the tightness of the connection between the adjacent standard segment templates 1. In this embodiment, the positioning movement of the positioning plate 4 and the connection of the two standard segment templates 1 can be carried out synchronously, greatly improving the convenience of operation.

[0028] In this embodiment, the length of the driving slope 11 on the second positioning part 10 is preferably greater than the length of the driving slope 11 on the first positioning part 9, the distance of the first positioning part 9 moving along the second positioning part 10 can be appropriately increased, so that the first positioning part 9 gradually pushes the second positioning part 10 to move as the support sleeve 8 moves along the axis of the bolt 6, increasing the tightness of the contact between the positioning plate 4 and the protrusion 2. In this example, a first limiting groove 12 is formed in the bolt 6 along the axis direction thereof, and a first limiting block slidingly located in the first limiting groove 12 is arranged in the support sleeve 8. In this way, the support sleeve 8 can be limited, avoiding synchronous rotation of the support sleeve 8 when the nut 7 rotates, ensuring the movement of the support sleeve 8 along the axis of the bolt 6.

[0029] Further, the first positioning part 9 can be adjusted radially along the support sleeve 8, and after the driving slope 11 is worn, the position of the first positioning part 9 can be adjusted appropriately to compensate for the distance generated between the first positioning part 9 and the second positioning part 10, so as to ensure the positioning effect. Specifically, a adjusting sleeve 13 is vertically arranged on the support sleeve 8, the adjusting sleeve 13 is internally provided with an internal thread, the adjusting sleeve 13 is threadedly connected with an adjusting screw 14, and the first positioning part 9 is slidingly arranged in the adjusting sleeve 13. By rotating the adjusting screw 14, the first positioning part 9 can be pushed to move towards the second positioning part 10, so as to adjust the distance between the first positioning part 9 and the second positioning part 10. Preferably, the adjusting screw 14 is rotationally connected with the first positioning part 9, the adjusting sleeve 13 is internally provided with a second limiting groove 15, the first positioning part 9 is provided with a second limiting block 16, and the second limiting block 16 is slidingly arranged in the second limiting groove 15. The connection between the adjusting screw 14 and the first positioning part 9 can increase the integrity of the two, and improve the convenience of the adjusting operation. In addition, the end of the positioning plate 4 away from the second positioning part 10 is provided with a rubber pad, so as to increase the tightness of the contact between the positioning plate 4 and the protrusion 2, and reduce the wear caused by the contact between the two.

[0030] In use, the protrusion 2 on one standard segment template 1 is inserted into the groove 3 on another standard segment template 1, the contact area of the two standard segment templates 1 is increased through the connection of the protrusion 2 and the groove 3, and the original gap trajectory of the two standard segment templates 1 is changed, so that the gap is changed from a straight line to a broken line structure with an angle. The stability of the connection of the standard segment template 1 is enhanced, and the probability of slurry running is reduced. The length of the groove 3 along the width direction of the standard segment template 1 is greater than the length of the protrusion 2 along the direction, so that the horizontal movement of the two adjacent standard segment templates 1 for butt joint is facilitated, and the installation and disassembly difficulty is reduced. While the two adjacent standard segment templates 1 are connected through the bolts 6, the positioning plate 4 can be adjusted to complete the positioning and abutment of the protrusion 2 by the positioning plate 4. The operation is simple, fast and convenient, and has high practicality.
