Most of the materials that cannot be used any longer can be cleaned directly by engineering machinery, but the large amount of scaffolding and formwork piled up on the construction site cannot be cleaned directly by engineering machinery and need to be removed manually step by step. However, the scaffolding and formwork are mixed with each other, resulting in a complex internal structure that cannot be directly observed. Therefore, during manual dismantling, accidents such as structural collapse and injuries to personnel often occur. Therefore, during dismantling, it is necessary to support the material pile from the inside to ensure structural stability, but the commonly used jacks cannot meet the construction requirements. First, it is impossible to enter the interior to arrange the jacks; second, the jacks use point support, which cannot effectively support the material pile that is not an integrated structure; third, it is impossible to make adaptive adjustments according to the progress of dismantling, and there is still a risk of collapse during the dismantling process. The present invention provides a top-return support device and an operating method for template removal to solve the above problems. Summary of the invention

[0029] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the drawings of the specification. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.
[0030] In the description of the present invention, it should be understood that the terms "center", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", etc., indicating the orientation or position relationship are based on the orientation or position relationship shown in the drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention.
[0031] like Figure 1 , 2 As shown in Figures 3, 4 and 5, a top-return support device for template removal includes a base structure 1, an airbag structure 2, a strut structure 3 and a monitoring device, wherein the airbag structure 2 is arranged on the base structure 1, the strut structures 3 are arranged in groups on the periphery of the base structure 1, the base structure 1 and the strut structure 3 are arranged on the ground, and the monitoring device is arranged on the base structure 1, the airbag structure 2 and the strut structure 3.
[0032] The present invention is used to solve the problem of safe dismantling of a pile of materials mixed with formwork and scaffolding. Due to the long-term stacking of formwork and scaffolding, part of the structure is decayed, and structural collapse is very likely to occur during the dismantling process, which may lead to personal injury. In addition, since the internal structure of the pile is unclear and the space is small, effective support cannot be provided. Conventional return-to-top support means is to use a jack, but since the jack adopts point support, it is impossible to provide stable return-to-top support for the overall structure with a complex structure, and during the dismantling process, the fulcrum point is easily changed due to structural changes, which may lead to structural collapse and the jack toppling over and losing its supporting function. Moreover, the jacks need to be arranged in groups to achieve effective support, and the installation of the jacks requires personnel to enter the pile for installation, which poses a great safety hazard. The existing return-to-top support means cannot solve the problem of return-to-top support inside the material pile. The inflatable airbag 21 of the airbag structure 2 of the present invention makes surface contact with the bottom of the material pile after being inflated, thereby realizing surface return-to-top support, increasing the contact area of the return-to-top support, and thus ensuring the stability of the return-to-top support. After the support rod structure 3 is deployed, it cooperates with the inflatable airbag 21 to form a point-to-surface combination return-to-top support system, which can not only assist in strengthening the supporting effect of the inflatable airbag 21, but also greatly increase the overall area and support stability of the return-to-top support after the support rod structure 3 is deployed, thereby ensuring effective support for the material pile and avoiding collapse of the material pile during demolition operations.
[0033] The technical problem solved by the present invention is to ensure the stability of the overall structure of the material pile through the return-to-top support device, to avoid deformation or collapse of the material pile during the demolition process as much as possible, and even if the material pile collapses during the demolition operation, due to the supporting effect of the return-to-top support device, large-scale and large-scale collapse will not occur, which can effectively ensure the safety of the operators, and even if the material pile collapses, the return-to-top support device can be adjusted to ensure that it still has a stable supporting effect on the material pile. The working principle of the present invention is that after the inflatable airbag 21 is inflated and expanded, it contacts the bottom of the material pile and contacts the surface of the material pile to play a planar support effect on the material pile, and under the real-time monitoring of the pressure sensor, the pressure is adjusted according to the load above, so as to ensure sufficient planar contact and support effect. The support rod structure 3 arranged around the inflatable airbag 21 is expanded according to the spatial structure of the lower part of the material pile and the support requirements. After the support rod structure 3 is adaptively expanded according to the situation, the material pile is supported by point support around the inflatable airbag 21, and a point-surface combination of support is formed with the surface support of the inflatable airbag 21. The point-surface combination of support can effectively increase the support area, and thus has a better supporting effect on the material pile with unknown specific structure. The point support arranged on all sides not only plays a role of stabilizing and strengthening the surface support through the rigid structure, but also can improve the supporting effect of the surface support, limit its support shape, and ensure the stability of the return support.
[0034] like Figure 5 As shown, the airbag structure 2 includes an inflatable airbag 21, a gas cylinder and a valve. The inflatable airbag 21 and the gas cylinder are both arranged on the base structure 1, the inflatable airbag 21 is connected to the gas cylinder, and the valve is arranged on the inflatable airbag 21. During the demolition construction process, the structure may deform as a whole and collapse locally, which will cause the structure at the bottom of the pile to deform and also cause the load of the return support to change. Therefore, during the construction process, it is necessary to adjust the pressure of the inflatable airbag 21 so that its support height and return support force meet the support requirements, thereby ensuring the stability of the overall structure of the pile and avoiding the collapse of the pile as much as possible; when the internal pressure of the inflatable airbag 21 is increased, it can still provide support of sufficient height when the load it bears is increased; when the upper load is reduced, the internal pressure of the inflatable airbag 21 is reduced to avoid deformation of the pile structure caused by excessive return force.
[0035] Furthermore, the valve includes an inlet valve and an outlet valve, both of which are solenoid valves and are connected to a control device, and the opening and closing of the inlet valve and the outlet valve are controlled by the control device. The inlet valve is arranged between the inflatable airbag 21 and the gas cylinder, and the inlet valve is controlled to inflate and pressurize. The outlet valve is arranged on the inflatable airbag 21, and the outlet valve is controlled to deflate and reduce the pressure.
[0036] like Figure 1 , 4As shown, further, the base structure 1 includes a base 11 and an adjusting rod group 12, and the adjusting rod group 12 is arranged on the base 11 at intervals, and the expansion and retraction of the support rod structure 3 are realized by telescoping. Each adjusting rod group 12 can be independently telescoped as needed to meet the requirements of the expansion size. The support rod structure 3 is arranged at the outer end of the adjusting rod group 12, and the airbag structure 2 is arranged on the base 11.
[0037] like Figure 4 , 5 As shown, further, the adjusting rod group 12 is connected to the control device, and the extension and retraction are realized by the control device. The adjusting rod group 12 includes a fixed sleeve and a telescopic rod. The fixed sleeve is hingedly connected to the base 11, and a hinge structure with a spring reset function is adopted. When the inflatable airbag 21 is not under pressure, the above structure can enable the adjusting rod group 12 to provide sufficient supporting force for the inflatable airbag 21, and will not cause the base 11 to contact the ground. When the inflatable airbag 21 is under pressure, the inflatable airbag 21 is forced to contact the ground together with the base 11 downward. After the pressure is released, the hinged structure is The reset function of the structure allows the base 11 to rise off the ground; the telescopic rod is movably arranged in the fixed sleeve and is extended and retracted in the fixed sleeve by electric control; the support rod structure 3 is hingedly connected to the outer end of the telescopic rod; after the inflatable airbag 21 is inflated and bears a certain pressure, the inflatable airbag 21 will press down so that the bottom surface of the base 11 contacts the ground, playing a role of stable support; after the inflatable airbag 21 squeezes the base 11, the two ends of the adjustment rod group 12 are hinged to achieve the downward displacement of the base 11 and contact with the ground, thereby ensuring the stability of the support.
[0038] like Figure 1 , 2 As shown in , 5 , further, the support rod structure 3 includes a movable base 31 and a lifting push rod 32 , the movable base 31 is vertically arranged at the outer end of the adjusting rod group 12 , and the lifting push rod 32 is vertically arranged in the movable base 31 .
[0039] Preferably, the support rod structure 3 is a hydraulic rod with crawler wheels at the bottom, which is connected to a control device and can move to the construction position by itself. A pressure sensor is provided on the lifting push rod 32. After the lifting push rod 32 is raised and the pressure it bears reaches a set value, it stops rising to provide stable support.
[0040] Furthermore, the monitoring device includes a pressure sensor, a position sensor and a control device. The pressure sensor is arranged on the airbag structure 2 and the strut structure 3, monitors the pressure in the inflatable airbag 21 and on the lifting push rod 32 in real time, transmits the pressure value to the control device, and controls the inflation and deflation of the inflatable airbag 21 and the lifting and lowering of the lifting push rod 32 after calculation. After the pile structure undergoes local deformation or collapse, such as partial collapse, which causes the pressure on one or several lifting push rods 32 to increase, and the pressure on the remaining lifting push rods 32 to decrease, the pressure in the inflatable airbag 21 increases. After the pressure sensor monitors the pressure change, it transmits the data to the control device, and after calculation, controls the lifting push rod 32 with increased pressure to descend, and controls the lifting push rod 32 with reduced pressure to rise. In the process of lifting and lowering adjustment of the lifting push rod 32, the inflatable airbag 21 is adjusted in real time to ensure that the pressure in the inflatable airbag 21 is within a stable range and the pressure value on the lifting push rod 32 does not fluctuate significantly, thereby achieving stable support for the pile. The position sensor is arranged on the base structure 1, and the position of the device is determined by the position sensor. The pressure sensor and the position sensor are connected to the control device.
[0041] Furthermore, a mobile power source is provided on the support rod structure 3, and the mobile power source is connected to the valve, the mobile base 31 and the monitoring device to provide energy for the valve, the mobile base 31 and the monitoring device.
[0042] Furthermore, the top of the lifting push rod 32 is hemispherical, and anti-skid grooves are arranged at intervals on the spherical surface to play an anti-skid role and improve the supporting stability of the lifting push rod 32.
[0043] Furthermore, the bottom of the mobile base 31 is provided with track wheels.

[0045] S1, device in place: determine the working position of the device according to the position and space of the removed template, then shrink the device to the initial state, and use the remote control drive device to move it to the working position;

[0047] S3, removing the formwork: the formwork is removed from the outside by means of a tower crane or a crane in cooperation with manual labor. If the formwork collapses and presses on the inflatable airbag 21 and the lifting push rod 32 during the removal process, the air pressure of the inflatable airbag 21 and the height of the lifting push rod 32 are adjusted in real time according to the pressure value monitored in real time by the pressure sensor to ensure that the inflatable airbag 21 and the lifting push rod 32 can provide sufficient supporting force to support the collapsed material pile and ensure the stability of the material pile structure. Then, the formwork is removed and the pressure of the inflatable airbag 21 and the height of each lifting push rod 32 are adjusted in real time to provide support.
[0048] S4, device retraction: after the template is removed, the inflatable airbag 21 is controlled to be deflated, the lifting push rod 32 is reset and the support rod structure 3 is retracted, and the device is controlled to move to the next construction position.
