[0020] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0021] Figures 2 and 3 The sealing structure is shown, which includes an integrated frame structure formed by splicing a frame a1 and a frame b2, and a split bladder arranged at the bottom of the integrated frame structure (the part in contact with the ground).

[0022] like Figure 5 As shown, there are multiple split-type capsules, which are evenly spaced and cover the bottom of the integrated frame structure. At the same time, each split-type capsule is completely independent and connected to the air source 4 through a separate air pipe 6.

[0023] The split bladder can achieve synchronous expansion or synchronous contraction as well as asynchronous expansion or asynchronous contraction.

[0024] The split airbag includes an elastic airbag a14 and an elastic airbag b24. The elastic airbag a14 and the elastic airbag b24 can be made of EPDM rubber, chloroprene rubber, natural rubber, nitrile rubber, silicone rubber, etc.

[0025] like Figures 1 to 6 As shown, a working method of a formwork sealing structure applied to a structural column formwork comprises the following steps: S1, according to the position of the structural column formwork reinforcement, frame a1 and frame b2 are spliced ​​together to form an integrated frame structure.

[0026] like Figure 4 As shown, in order to achieve the splicing of frame a1 and frame b2, a latch 15 extends from the side of the splicing portion a11 away from frame b2, and a slot 25 matching the latch 15 is provided at a corresponding position of frame b2.

[0027] The splicing of frame a1 and frame b2 can be completed by inserting the pin 15 into the slot 25. At the same time, in order to enhance the sealing of the splicing seam between frame a1 and frame b2, a soft sealing layer is provided at the splicing portion a11 of frame a1 and the splicing portion b21 of frame b2. The soft sealing layer is made of natural rubber, nitrile rubber, silicone rubber, etc.

[0028] S2, pre-pressure injection is performed on the split bladder.

[0029] Frame a1 and frame b2 are respectively provided with air pressure control components a13 and air pressure control components b23, which are respectively connected to the elastic airbag a14 and the elastic airbag b24 to obtain the air pressure inside the elastic airbag a14 and the elastic airbag b24, and to control the air pressure inside the elastic airbag a14 and the elastic airbag b24.

[0030] The air pressure control component a13 and the air pressure control component b23 are respectively provided with solenoid valves and pressure sensors with the same number as the elastic airbags a14 and the elastic airbags b24, wherein the solenoid valves are used to control the connection status between the elastic airbag a14 or the elastic airbag b24 and the air source 4, and the pressure sensors are used to obtain the air pressure inside the elastic airbag a14 and the elastic airbag b24.

[0031] When performing pre-pressure injection, according to the set pre-pressure, the controller 5 controls the solenoid valve to open, and the compressed gas in the gas source 4 is injected into each elastic airbag a14 and elastic airbag b24 respectively. After reaching the set pre-pressure, the controller 5 closes the solenoid valve to stop inflating the elastic airbag a14 and elastic airbag b24.

[0032] Among them, adjacent elastic airbags a14 are isolated from each other, and adjacent elastic airbags b24 are isolated from each other.

[0033] Different elastic airbags a14 or elastic airbags b24 can be inflated synchronously or asynchronously. After the air pressure in all elastic airbags a14 and elastic airbags b24 reaches the set pre-pressure, the controller 5 closes the solenoid valve.

[0034] The above-mentioned injection pre-pressure is used to initially expand the bladder, fit the template and reserve space, laying the foundation for subsequent high-pressure injection.

[0035] S3, the structural column formwork is supported based on the integrated frame structure.

[0036] A soft sealing layer is provided on the top of the splicing part a11 and the splicing part b21. The soft sealing layer is made of natural rubber, nitrile rubber, silicone rubber, etc. Its function is to improve the fit between the splicing part a11 and the splicing part b21 and the structural column formwork, and enhance the sealing between the splicing part a11 and the splicing part b21 and the structural column formwork.

[0037] S4, after the construction column formwork is supported, the split-type bladder is pressure-injected so that the sealing structure can seal between the construction column formwork and the ground.

[0038] The injection pressure must be sufficient to overcome the side pressure of the concrete and to block the gap between the structural column formwork and the ground after the elastic airbag a14 or the elastic airbag b24 expands. The specific injection pressure is set according to actual conditions.

[0039] S5, monitoring the pressure in the split bladder, and when identifying abnormal pressure in the split bladder, adjusting the pressure of the split bladders surrounding the abnormal split bladder to take over the function of the abnormal split bladder.

[0040] Since there are many types of objects that can destroy the split bladder structure at the construction site, such as steel piles, wires, construction tools, etc., in order to ensure its stable and normal operation during the use of this sealing structure, it is also necessary to monitor the pressure inside the split bladder.

[0041] Under normal conditions, the split airbag body is not damaged, and the elastic airbag a14 or the elastic airbag b24 has normal pressure during the inflation process.

[0042] Under abnormal conditions, the split airbag body is damaged (such as perforated or cut, resulting in air leakage), and abnormal pressure occurs in the elastic airbag a14 or the elastic airbag b24 during the inflation process.

[0043] Under abnormal conditions, when the pressure of the split bladder is abnormal, it will lead to insufficient expansion, which will cause the squeezing force between it and the adjacent split bladder to decrease, resulting in insufficient sealing performance.

[0044] When the controller 5 identifies that the pressure of one of the split-type bladders (either the elastic airbag a14 or the elastic airbag b24) is abnormal, it adjusts the air pressure enhancement expansion degree of the surrounding split-type bladders according to the position of the split-type bladder, thereby supplementing the function of the split-type bladder with abnormal pressure and avoiding affecting the casting process of the structural column formwork.

[0045] like Figure 3 and 5 As shown, the structure of the frame a1 includes a splicing portion a11, and a mounting plate a12 extends from the side of the splicing portion a11 away from the frame b2. An air pressure control component a13 is provided on the mounting plate a12. The bottom of the splicing portion a11 has a number of elastic airbags a14 arranged at equal intervals, and the elastic airbags a14 cover the bottom of the splicing portion a11. Solenoid valves and pressure sensors with the same number as the elastic airbags a14 are provided in the air pressure control component a13. The elastic airbags a14 are connected to the air source 4 through the air pipe 6. The solenoid valves and pressure sensors are arranged on the pipeline. The controller 5 is respectively communicated with the solenoid valves and pressure sensors arranged in the air pressure control component a13.

[0046] like Figure 3 and 5As shown, the structure of the frame b2 includes a splicing portion b21, and a mounting plate b22 extends from the side of the splicing portion b21 away from the frame a1, and an air pressure control component b23 is provided on the mounting plate b22. The bottom of the splicing portion b21 has a number of elastic airbags b24 arranged at equal intervals, and the elastic airbags b24 cover the bottom of the splicing portion b21. The air pressure control component b23 is provided with solenoid valves and pressure sensors with the same number as the elastic airbags b24. The elastic airbags b24 are connected to the air source 4 through the air pipe 6. The solenoid valves and pressure sensors are set on the pipeline, and the controller 5 is respectively communicated with the solenoid valves and pressure sensors set in the air pressure control component b23.

[0047] like Figure 4 As shown, the integrated frame structure is fixed by a detachable lock 3, including a fixing seat a31 and a fixing seat b, wherein the fixing seat a31 is arranged on the surface of the splicing part a11, and the fixing seat b is arranged on the surface of the splicing part b21. After the frame a1 and the frame b2 are spliced ​​together, the fixing seat a31 and the fixing seat b can be connected by a screw rod 33, and a rotating handle 34 is movably provided at one end of the screw rod 33.

[0048] The screw rod 33 is threadedly connected to the fixing seat a31 and the fixing seat b respectively. After the pin 15 is inserted into the slot 25, the screw rod 33 is rotated by rotating the handle 34 to connect the fixing seat a31 and the fixing seat b together to achieve the fixation of the integrated frame structure after splicing.

[0049] The above-mentioned detachable buckle can also adopt other forms. As long as it can realize the fixation of the integrated frame structure after splicing, it can be used in the above-mentioned structure. The above-mentioned detachable buckle disclosed is only a structural form of the detachable buckle used after the integrated frame structure is spliced, and should not be regarded as a limitation to this application.

[0050] It should be noted that the specific models and specifications of the controller 5, solenoid valve, and pressure sensor need to be selected and determined based on the actual specifications of the device. The specific selection calculation method adopts the existing technology in this field, so it will not be described in detail.

[0051] The power supply and principles of the controller 5 , the solenoid valve, and the pressure sensor are clear to those skilled in the art and will not be described in detail here.

[0052] Obviously, those skilled in the art may make various changes and modifications to the present invention without departing from the spirit and scope of the present invention. Thus, if such changes and modifications fall within the scope of the claims and their equivalents, the present invention is intended to include such changes and modifications.
