Different from the onshore structure in the construction environment, the erection of the support system requires the use of the structure itself as the support system for the next process. Therefore, how to effectively divide the structure and fully use its own bearing capacity for the construction of the next process to achieve stable support while meeting the safety and durability of the structure has become an important issue that needs to be studied in the prior art; at the same time, since the bottom surface of the working platform is close to the water surface, the bottom formwork is subject to the impact pressure of water waves. How to ensure the stable installation of the bottom formwork and side formwork is also a difficult problem faced by concrete construction on the water. Utility Model Content

[0023] like Figure 1-Figure 2As shown, the utility model discloses a cast-in-place support formwork installation structure, including a pile foundation steel casing 1, a cast-in-place support 2, a bottom formwork 3 and a side formwork 4. The pile foundation steel casing 1 is left in place after the pile foundation construction is completed for the subsequent installation of the cast-in-place support 2. The cast-in-place support 2 is fixedly connected to the pile foundation steel casing 1, and includes a main beam 2.1 and a distribution beam 2.2 fixedly connected to the main beam 2.1. The main beam 2.1 is arranged between the pile foundation steel casings 1 and is welded and fixed to the upper end of the pile foundation steel casing 1. The distribution beam 2.2 is connected in parallel to the side of the main beam 2.1, and the top surface of the distribution beam 2.2 is flush with the top surface of the main beam 2.1; the bottom formwork 3 is laid on the cast-in-place support 2, and a back rib is provided on the back of the bottom formwork 3. The back rib is intermittently welded to the distribution beam 2.2 on the cast-in-place support 2, which can increase the stability of the bottom formwork installation and prevent the bottom formwork from being subjected to the impact pressure of waves and affecting its stability. Multiple bottom molds are provided, and the multiple bottom molds are bolted and fixed, and double-sided tape is pasted between adjacent bottom molds to prevent leakage during subsequent concrete pouring.

[0024] The side form 4 is arranged at the end of the bottom form and is located above the cast-in-place support 2. The lower end of the side form 4 is connected to the main beam 2.1 through a tension screw 5. The main beam 2.1 adopts a double I-beam structure. In one embodiment of the present application, one end of the tension screw 5 passes through the side form 4 and is locked with the side form 4 by a nut, and the other end passes through the I-beam web on the side of the main beam 2.1 close to the side form 4 and is locked by a nut and a pad.

[0025] Since the main beam 2.1 of the present application adopts a double-work steel structure for the safety of construction, it is extremely inconvenient to fix the nut when the tension bolts are connected to the I-beam. Therefore, in another embodiment of the present application, a fixing rod 5.1 is provided on the side of the tension bolt, and a mounting hole for setting a pin 5.2 is provided near the end of the tension screw 5. The middle part of the fixing rod 5.1 is connected to the tension screw 5 through the pin 5.2, and the fixing rod 5.1 can rotate through the pin 5.2. When in use, the fixing rod 5.1 is parallel to the axis of the tension screw 5, the fixing rod 5.1 and the tension screw 5 are passed through the web of the I-beam, and then the fixing rod 5.1 is controlled to be perpendicular to the axis of the tension screw 5, so that the fixing rod 5.1 is against the web, and the tension screw 5 is connected to the web of the I-beam, thereby avoiding the process of installing nuts in a small space and making the installation more convenient.

[0026] The lower part of the side surface of the side form 4 is connected to the main beam 2.1 through the lower diagonal brace 6, and the upper part of the side surface is connected to the main beam 2.1 through the upper diagonal brace 7, wherein ear plates are welded on the side form 4 and the main beam 2.1, and the lower diagonal brace 6 and the upper diagonal brace 7 are connected and fixed to the ear plates at corresponding positions by bolts.

[0027] A channel steel 8 is provided at the upper end of the side form 4 , and the channel steel 8 is connected to the side form 4 through a tie rod 9 , and the channel steel 8 is connected to a steel bar 10 skeleton of a structure to be cast below through the steel bar 10 .

[0028] The present application retains the pile foundation steel casing 1 and uses the existing pile foundation steel casing 1 as a bearing structure for installing the cast-in-place bracket 2. There is no need to set up a new supporting structure. For water construction, the construction is more convenient and more efficient. In addition, the bottom mold is intermittently welded to the cast-in-place bracket 2 to ensure the stability of the bottom mold installation. The side mold 4 is provided with corresponding reinforcement measures at the bottom, top and sides, which has better stability.

[0029] The embodiments described above are merely descriptions of preferred implementation modes of the present invention, and are not intended to limit the scope of the present invention. Without departing from the design spirit of the present invention, various modifications and improvements made to the technical solutions of the present invention by ordinary technicians in this field should all fall within the protection scope determined by the claims of the present invention.
