[0002] With the development of ecological restoration construction projects, the construction technology of wall formwork engineering still needs to be improved to meet the requirements of wall construction, so as to provide a strong guarantee for ecological environment governance and ecological environment restoration project engineering.

[0003] Currently, related wall formwork erection structures, such as the Chinese patent "Bottom Support and Fixing Structure and Method of Wall Formwork" with the authorization announcement number CN108868133A, disclose a bottom support and fixing structure and method of a wall formwork, including a wall formwork and bottom through-wall tie rods and vertical support members exposed on both side walls of the bottom wall. The vertical support members are fixed tightly on both side walls through dovetail clamps, fastening nuts and bottom through-wall tie rods. The upper end faces of the vertical support members are flush. A horizontal support member is provided above the vertical support members. The vertical support members and the horizontal support member form a T-shaped structure in the vertical plane. The horizontal support member is flush with the reference line at the bottom of the wall formwork. The wall formwork is fixed above the horizontal support member through main keels, secondary keels and upper through-wall tie rods.

[0004] The following deficiencies exist in the above-mentioned related technologies: Related large-scale concrete pouring wall formwork erection devices are prone to insufficient formwork erection strength, resulting in the formwork bulging or even expanding after the concrete slurry is poured. Summary of the Invention

[0005] In order to improve the formwork erection strength and reduce the occurrence of formwork bulging or expanding, this application provides a formwork erection device and method for an energy-saving and heat-insulating wall.

[0006] In the first aspect, a formwork erection device for an energy-saving and heat-insulating wall provided by this application adopts the following technical solution:

[0007] A formwork erection device for an energy-saving and heat-insulating wall includes two relatively arranged heat-insulating formworks and a tie rod passing through the two heat-insulating formworks. Nuts for tightening the two heat-insulating formworks are threadedly installed at both ends of the tie rod. A plurality of inner support mechanisms for reducing the formwork expansion of the heat-insulating formworks are provided on one side where the two heat-insulating formworks are close to each other, and a plurality of outer support mechanisms for improving the stability of the heat-insulating formworks are provided on one side where the two heat-insulating formworks are far from each other.

[0008] By adopting the above technical solution, when setting up the thermal insulation formwork support device, the inner support mechanism is arranged between two thermal insulation formworks, which can limit the distance between the two thermal insulation formworks. The outer support mechanism is arranged on the outer sides of the two thermal insulation formworks to tighten the two thermal insulation formworks. When pouring concrete slurry between the two thermal insulation formworks, the inner support mechanism and the outer support mechanism act together to improve the support strength of the thermal insulation formworks.

[0009] Optionally, the inner support mechanism includes an adjustment pipe for limiting the thickness of the cast wall. The pull rod is coaxially arranged inside the adjustment pipe. Both ends of the adjustment pipe are provided with abutting plates that abut against the thermal insulation formworks, and the sides of the abutting plates away from the adjustment pipe abut against the thermal insulation formworks respectively.

[0010] By adopting the above technical solution, when installing the inner support mechanism, select an adjustment pipe with a suitable length so that the sum of the length of the adjustment pipe and the thickness of the two abutting plates is equal to the thickness of the wall to be cast. At the same time, the adjustment pipe and the abutting plates can limit the distance between the two thermal insulation formworks. When the pull rod tightens the two thermal insulation formworks under the action of the nut, the distance between the two thermal insulation formworks can be ensured to be constant; when the formwork is removed after the wall is cured and formed, the abutting plates and the adjustment pipe are fixed in the concrete wall, enhancing the wall strength. At the same time, due to the existence of the abutting plates, the contact area between the concrete and the thermal insulation formworks is reduced, facilitating the formwork removal work.

[0011] Optionally, the inner support mechanism further includes a tensioning assembly. The tensioning assembly includes a horizontal pipe. Both ends of the horizontal pipe are fixed with inclined pipes that are gradually inclined upward from the side close to the horizontal pipe to the side away from the horizontal pipe. The ends of the inclined pipes away from the horizontal pipe are rotatably connected to the abutting plates.

[0012] By adopting the above technical solution, when the concrete is poured between the two thermal insulation formworks, the horizontal pipe is subjected to the gravity of the downward flowing concrete. At this time, the inclined pipes drive the abutting plates to approach each other, so that the abutting plates can be more tightly abutted against the adjustment pipe, thereby reducing the occurrence of formwork bulging after the concrete is poured.

[0013] Optionally, a connecting rod is also arranged between adjacent horizontal pipes.

[0014] By adopting the above technical solution, the connecting rod is arranged on the horizontal pipe to connect adjacent horizontal pipes. When the gravity of the falling concrete acts on the horizontal pipe, adjacent horizontal pipes can jointly bear the gravity of the concrete, so as to ensure that the abutting plates can tightly abut against the adjustment pipe in the direction of approaching each other, reducing the occurrence of formwork bulging.

[0015] Optionally, absorbent cotton cloth is also filled in the horizontal pipe and the inclined pipe. A water injection port communicating with the inclined pipe is opened on the abutting plate, and a plurality of water outlet holes are opened on the horizontal pipe.

[0016] By adopting the above technical solution, after the heat-insulating formwork is removed, it is usually necessary to water-cure the wall. Since the wall is vertically arranged, it is not easy for water to enter the wall. At this time, the horizontal pipe and the inclined pipe can serve as water-conducting channels. Water enters the inclined pipe from the water injection port and flows to the horizontal pipe. The water-absorbing cotton cloth can absorb water and provide water during the hydration reaction of the concrete. At the same time, the water-absorbing cotton cloth can reduce the situation that the water outlet on the horizontal pipe is blocked by concrete slurry.

[0017] Optionally, the outer support mechanism includes a reinforcing rod. The reinforcing rod is located on the side where the two heat-insulating formworks are away from each other. The pull rod penetrates through the reinforcing rod. The side of the reinforcing rod away from the heat-insulating formwork abuts against the nut. A fixing component is arranged on the side of the reinforcing rod close to the heat-insulating formwork. The fixing component is arranged along the height direction of the heat-insulating formwork and abuts tightly against the heat-insulating formwork.

[0018] By adopting the above technical solution, when the nut abuts tightly against the reinforcing rod, the heat-insulating formwork is tightened by the pulling force of the pull rod. At the same time, since there is a fixing component between the reinforcing rod and the heat-insulating formwork, the fixing component can support the heat-insulating formworks at different positions and heights, thereby reducing the situation that the heat-insulating formwork on the side away from the ground is inclined.

[0019] Optionally, the fixing component includes a fixing ring sleeved on the pull rod, and the fixing ring abuts against the side of the reinforcing rod away from the nut. Two fixing rods are also hinged on the fixing ring. The two fixing rods are symmetrically arranged with respect to the fixing ring. The length of the fixing rod is not less than the distance between the fixing ring and the heat-insulating formwork. Abutting strips are inserted at the ends of the fixing rods away from the fixing ring. The abutting strips are arranged along the length direction of the heat-insulating formwork and abut against the heat-insulating formwork.

[0020] By adopting the above technical solution, when the nut abuts tightly against the reinforcing rod, the reinforcing rod abuts tightly against the fixing ring, the fixing rod hinged to the fixing ring abuts tightly against the abutting strip, and the abutting strip abuts tightly against the heat-insulating formwork, giving a force that makes the two heat-insulating formworks approach each other, reducing the situation of formwork bulging. At the same time, a stable triangular structure is formed between the fixing rod and the heat-insulating formwork, and the fixing rod is arranged along the height direction of the heat-insulating formwork, which can reduce the overall inclination of the heat-insulating formwork and ensure the stability of the installation of the heat-insulating formwork.

[0021] In a second aspect, the formwork erection method of a formwork erection device for an energy-saving and heat-insulating wall provided by the present application adopts the following technical solution:

[0022] A formwork erection method of a formwork erection device for an energy-saving and heat-insulating wall includes the following steps:

[0023] S1: First, install the internal support mechanism between two thermal insulation formworks. Determine the length of the adjusting pipe according to the thickness of the wall to be cast. Insert both ends of the adjusting pipe into the abutting plates, and the abutting plates are in contact with the thermal insulation formworks. The tie rods penetrate through the thermal insulation formworks, the abutting plates and the adjusting pipe at the same time. Then, install the tightening assembly between the two abutting plates;

[0024] S2: Then, symmetrically install the external support mechanism on the sides of the two thermal insulation formworks away from each other. Place the abutting strips on the outside of the thermal insulation formworks, and insert the fixing rods into the abutting strips. At the same time, the fixing rings hinged to the fixing rods are coaxially inserted into the tie rods. The strengthening rods are inserted into multiple parallel tie rods at the same time, and one side of the strengthening rod is in contact with the fixing ring, and the other side of the strengthening rod is in contact with the nuts, and the nuts are threadedly connected to both ends of the tie rods;

[0025] S3: After the internal support mechanism and the external support mechanism are installed, a casting space is formed between the two thermal insulation formworks. After the concrete slurry is cast into the casting space, the wall casting work is completed.

[0026] By adopting the above technical solutions, the internal support mechanism can support inside the thermal insulation formworks. The adjusting pipe ensures a constant distance between the two thermal insulation formworks. The gravity during casting is converted into the force that makes the two thermal insulation formworks approach each other, so that the abutting plates and the adjusting pipe are kept in a tightly abutted state, reducing the leakage of slurry at the connection between the adjusting pipe and the abutting plates. At the same time, it can reduce the direct extrusion of the concrete slurry on the thermal insulation formworks, thereby reducing the occurrence of formwork bulging; and the internal support mechanism solidifies with the concrete slurry to form the wall, improving the strength of the wall; after the wall is formed, the abutting plates are fixed on the wall surface, reducing the contact area between the thermal insulation formworks and the concrete wall surface, and thus achieving the effect of convenient form removal. After the form removal is completed, when the concrete wall surface needs to be watered and cured, the hollow structure of the tightening assembly provides a water conduction channel for watering and curing, providing sufficient water for the later hydration reaction of the concrete wall, and improving the strength of the wall after forming.

[0027] The external support mechanism is arranged on the outside of the two thermal insulation formworks. When the nuts tighten the strengthening rods, the fixing assembly can effectively support the thermal insulation formworks at different positions and heights, and at the same time can tighten the two thermal insulation formworks. The external support mechanism further improves the formwork support strength and reduces the occurrence of formwork bulging and formwork swelling.

[0028] In summary, the present application includes at least one of the following beneficial technical effects:

[0029] 1. The inner support mechanism can support inside the thermal insulation formwork. The adjusting pipe ensures a constant distance between the two thermal insulation formworks. By utilizing the gravity during pouring to convert it into the force for the two thermal insulation formworks to approach each other, the abutting plate and the adjusting pipe are kept in a tightly abutted state, reducing the leakage of slurry at the connection between the adjusting pipe and the abutting plate. Meanwhile, it can reduce the direct extrusion of the concrete slurry on the thermal insulation formwork, thereby reducing the occurrence of formwork bulging for the thermal insulation formwork;

[0030] 2. The inner support mechanism solidifies together with the concrete slurry to form an energy-saving and thermal insulation wall, improving the strength of the wall. After the wall is formed, the abutting plate is fixed on the surface of the wall, reducing the contact area between the thermal insulation formwork and the concrete wall surface, and thus achieving the effect of convenient form removal. After form removal, when the concrete wall surface needs to be watered for curing, the hollow structure of the tensioning component provides a water conduction channel for watering curing, providing sufficient water for the later hydration reaction of the concrete wall and improving the strength of the wall after formation;

[0031] 3. The outer support mechanism is arranged outside the two thermal insulation formworks. When the nut tightly abuts the reinforcing rod, the fixing component can effectively support the thermal insulation formworks at different positions and heights, and at the same time can tension the two thermal insulation formworks. The outer support mechanism further improves the formwork erection strength for the thermal insulation formworks, reducing the occurrence of formwork bulging and formwork swelling for the thermal insulation formworks.

[0032] 4. The wall formwork erection device of the present application is applied to the project works of ecological environment governance and ecological environment restoration, having good formwork erection strength and contributing to improving the strength of the wall after formation. The thermal insulation formwork is beneficial to improving the curing effect on the wall.

[0033] 5. Thermal insulation materials and recycled recycled aggregates are incorporated into the concrete slurry poured in the present application, making the resulting wall have good thermal insulation effect, reducing waste of resources, and having the effect of energy conservation and environmental protection.

Detailed implementation manners

[0039] The following will Figures 1-4 further describe the present application in detail.

[0040] An embodiment of the present application discloses a formwork erection device for an energy-saving and heat-insulating wall.

[0041] Referring to Figure 1 , a formwork erection device for an energy-saving and heat-insulating wall includes two vertically arranged heat-insulating formworks 1. The space between the two heat-insulating formworks 1 forms a space for pouring concrete slurry. A plurality of tie rods 2 are horizontally penetrated through the two heat-insulating formworks 1. The plurality of tie rods 2 are distributed at intervals in an array on the heat-insulating formworks 1. An inner support mechanism 3 is provided on one side of the two heat-insulating formworks 1 close to each other. The number of the inner support mechanism 3 is the same as that of the tie rods 2. A plurality of outer support mechanisms 4 are provided on one side of the two heat-insulating formworks 1 away from each other. And the outer support mechanisms 4 are symmetrically arranged with respect to the pouring space. The plurality of outer support mechanisms 4 are arranged along the height direction of the heat-insulating formworks 1. The tie rods 2 penetrate through the inner support mechanism 3, the outer support mechanism 4 and the heat-insulating formworks 1 at the same time. And nuts 21 are threadedly installed at both ends of the tie rods 2. Under the action of the tie rods 2 and the nuts 21, the inner support mechanism 3 and the outer support mechanism 4 enhance the erection strength of the heat-insulating formworks 1 and reduce the occurrence of formwork bulging and warping of the heat-insulating formworks 1.

[0042] The concrete slurry is obtained by mixing cement, water, recycled aggregate, sand, fly ash and heat-insulating materials such as perlite and glass wool, so that the cast wall has good heat-insulating effect, and at the same time realizes the recycling of waste recycled aggregate and reduces the waste of resources; the material of the heat-insulating formworks 1 is made of refractory material and heat-insulating material, so that it has heat-insulating and heat-preserving effects. When the wall casting is completed, it is necessary to spray water for curing at a specific temperature. The heat-insulating formworks 1 can reduce the heat dissipation during the wall curing and is beneficial to the wall having good strength after curing.

[0043] Referring to Figure 2, the inner support mechanism 3 includes an adjustment pipe 31 horizontally arranged between two thermal insulation templates 1. A pull rod 2 horizontally penetrates coaxially through the adjustment pipe 31. Vertical abutting plates 32 are inserted at both ends of the adjustment pipe 31. The side of the abutting plate 32 away from the adjustment pipe 31 abuts against the inner wall of the thermal insulation template 1. Through holes 321 horizontally communicating with the adjustment pipe 31 are formed in the abutting plates 32. On the side of the abutting plate 32 close to the adjustment pipe 31, a plugging ring 322 for inserting the end of the adjustment pipe 31 is also fixed. The diameter of the plugging ring 322 is larger than that of the through hole 321, so that the end of the adjustment pipe 31 can be horizontally inserted into the plugging ring 322, and the same pull rod 2 can horizontally penetrate through the adjustment pipe 31, the through hole 321 and the thermal insulation template 1 at the same time.

[0044] The length of the adjustment pipe 31 can be selected according to the actual thickness of the wall to be cast. The adjustment pipe 31 ensures that the distance between the two thermal insulation templates 1 remains constant. The sum of the widths of the adjustment pipe 31 and the abutting plates 32 inserted at both ends of the adjustment pipe 31 is equal to the thickness of the cast wall. Each pull rod 2 is inserted into the adjustment pipe 31, which is convenient for removing the pull rod 2 from the wall after the subsequent construction is completed, saving manpower.

[0045] Refer to Figure 1 and Figure 3 , the inner support mechanism 3 further includes a tensioning assembly 33 located between the two abutting plates 32, and the tensioning assembly 33 is located below the adjustment pipe 31. The projection of the tensioning assembly 33 and the adjustment pipe 31 in the vertical direction is not in the same plane. The tensioning assembly 33 includes a horizontally arranged horizontal pipe 331. Inclined pipes 332 are fixedly penetrated at both ends of the horizontal pipe 331. The inclined pipes 332 are gradually inclined upward from the side close to the horizontal pipe 331 to the side away from the horizontal pipe 331. The end of the inclined pipe 332 away from the horizontal pipe 331 is hinged to the abutting plate 32. Two rotating rods 3321 perpendicular to the axis of the inclined pipe 332 are fixed on the outer side wall of the inclined pipe 332. The axes of the two rotating rods 3321 are on the same straight line. A fixing hook 323 for inserting the rotating rod 3321 is fixed on the side of the abutting plate 32 close to the inclined pipe 332. The rotating rod 3321 is inserted into the fixing hook 323, so that the abutting plate 32 and the inclined pipe 332 can rotate on the vertical plane.

[0046] When the concrete slurry is poured between the two thermal insulation templates 1, the tensioning assembly 33 is affected by the gravity of the concrete slurry. Since the abutting plate 32 is rotatably connected to the inclined pipe 332, a force is given to the abutting plate 32 to move in the direction of approaching each other, so that the abutting plate 32 is more tightly abutted against both ends of the adjustment pipe 31, reducing the situation of formwork bulging caused by the injection of concrete slurry, and at the same time reducing the situation of slurry leakage from the connection between the adjustment pipe 31 and the abutting plate 32.

[0047] Refer to Figure 1 and Figure 4, a water injection port 324 communicating with the inclined pipe 332 is further opened on the abutting plate 32. The horizontal pipe 331 and the inclined pipe 332 are filled with absorbent cotton cloth 333. A plurality of water outlet holes 3311 are penetratingly opened on the circumferential surface of the horizontal pipe 331. When watering and curing are required after the wall is cast and formed, when watering and curing the wall surface, water enters the inclined pipe 332 from the water injection port 324 and flows into the horizontal pipe 331. The absorbent cotton cloth 333 can absorb the water entering the inclined pipe 332 to play a role in guiding and storing water, providing sufficient water for the subsequent hydration reaction of the concrete, improving the curing effect on the wall, and thus improving the strength of the wall after forming. The absorbent cotton cloth 333 also reduces the situation that the concrete slurry enters the horizontal pipe 331 from the water outlet holes 3311 and causes the concrete slurry to overflow reversely from the water injection port 324.

[0048] A connecting rod 34 is also lapped between adjacent horizontal pipes 331. The connecting rod 34 is wavy. The length direction of the connecting rod 34 is perpendicular to the axis of the horizontal pipe 331, and the projection of the connecting rod 34 and the water outlet holes 3311 on the vertical plane do not coincide. The connecting rod 34 connects adjacent horizontal pipes 331. When the concrete slurry is poured on the tensioning assembly 33, the connecting rod 34 can enable adjacent horizontal pipes 331 to jointly bear the gravity of the falling concrete slurry, thereby giving the abutting plate 32 a force to approach each other, reducing the situation of formwork bulging or swelling of the thermal insulation formwork 1 caused by the concrete pouring.

[0049] Refer to Figure 1 and Figure 2 , a plurality of vertically arranged wooden squares 11 are abutted on one side of the two thermal insulation formworks 1 away from each other. The wooden squares 11 are arranged at intervals along the length direction of the thermal insulation formwork 1. An abutting strip 12 is abutted on the side of the wooden square 11 away from the thermal insulation formwork 1. The abutting strip 12 is perpendicular to the wooden square 11, and the abutting strips 12 are arranged at intervals along the height direction of the thermal insulation formwork 1. The outer support mechanism 4 is located on the side of the abutting strip 12 away from the wooden square 11. The wooden squares 11 and the abutting strips 12 make the outer support mechanism 4 more evenly stressed when abutting against the thermal insulation formwork 1.

[0050] The outer support mechanism 4 includes a plurality of fixing components 41. The plurality of fixing components 41 are arranged along the height direction of the thermal insulation formwork 1. The installation quantity of the fixing components 41 can be adjusted according to the height of the wall to be cast.

[0051] The fixing component 41 includes a fixing ring 411 and a fixing rod 412. Two fixing rods 412 are symmetrically hinged on each fixing ring 411. The length of the fixing rod 412 is not shorter than the distance between the fixing ring 411 and the wooden square 11. The fixing ring 411 is coaxially sleeved on the pull rod 2. A plugging rod 4121 is fixed at one end of the fixing rod 412 away from the fixing ring 411. Plugging grooves 121 are formed on both the upper surface and the lower bottom surface of the abutting strip 12. The plugging grooves 121 can be used for the insertion or extraction of the plugging rod 4121. When the plugging rod 4121 is inserted into the plugging groove 121, the plugging fixation of the fixing rod 412 and the abutting strip 12 is realized.

[0052] A reinforcing rod 42 abuts against one side of the fixing ring 411 away from the fixing rod 412. The reinforcing rod 42 is vertically arranged, and a plurality of through holes 421 for the pull rod 2 to pass through are spaced apart on the reinforcing rod 42. The through holes 421 are aligned with the pull rod 2 one by one and are inserted into each other. The side of the reinforcing rod 42 away from the fixing ring 411 abuts tightly against the nut 21. Since the nut 21 is threadedly connected to the end of the pull rod 2, the fixing component 41 can be stably supported outside the wooden square 11.

[0053] The outer support mechanism 4 plays a role in stably supporting the two heat preservation templates 1, reducing the inclination of the heat preservation templates 1 at different positions and heights, enhancing the overall stability of the formwork support device. At the same time, when the nut 21 abuts tightly against the reinforcing rod 42, on the one hand, a tensile force is given to the two heat preservation templates 1 to reduce the formwork expansion of the heat preservation templates 1. On the other hand, the fixing component 41 is tightened, so that a stable triangular structure is formed between the fixing rod 412 and the heat preservation template 1, and the heat preservation templates 1 at different positions and heights can be stably supported.

[0054] The implementation principle of the formwork support device for an energy-saving and heat-preserving wall in the embodiment of the present application is as follows:

[0055] The inner support mechanism 3 can support inside the heat preservation template 1, which is convenient for determining the distance between the two heat preservation templates 1. The tensioning component 33 converts the gravity generated when the concrete slurry is poured into the force that makes the two heat preservation templates 1 approach each other, so that the abutting plate 32 and the adjusting pipe 31 remain in a tightly abutted state, reducing the leakage of the slurry at the connection between the adjusting pipe 31 and the abutting plate 32. At the same time, it can reduce the direct extrusion of the concrete slurry on the heat preservation template 1, thereby reducing the formwork expansion of the heat preservation template 1; and the inner support mechanism 3 is solidified together with the concrete slurry to form a wall, improving the strength of the wall; after the wall is formed, the abutting plate 32 is fixed on the wall surface, reducing the contact area between the heat preservation template 1 and the concrete wall surface, and then realizing the effect of convenient form removal and reducing unnecessary damage to the wall during form removal; after form removal, when the concrete wall needs to be watered and cured, the through holes 321 on the abutting plate 32 and the hollow structure of the tensioning component 33 provide a water conduction channel for watering and curing, improving the curing effect on the wall.

[0056] The outer support mechanism 4 is arranged on the outer sides of the two heat preservation templates 1. When the nut 21 abuts against the reinforcing rod 42, the fixing assembly 41 can effectively support the heat preservation templates 1 at different positions and heights, and can also tension the two heat preservation templates 1 at the same time. The outer support mechanism 4 further improves the support strength of the heat preservation templates 1 and reduces the occurrence of bulging and swelling of the heat preservation templates 1.

[0057] The wall formwork erection device of the present application is applied to the project of ecological environment governance and restoration, and has the advantages of high support strength and good wall maintenance effect.

[0058] A formwork erection method for a formwork erection device of an energy-saving and heat-insulating wall disclosed in an embodiment of the present application includes the following steps:

[0059] S1: First, install the inner support mechanism 3 between the two heat preservation templates 1. Determine the length of the adjusting pipe 31 according to the thickness of the wall to be cast. Insert the two ends of the adjusting pipe 31 into the abutting plates 32 respectively, so that the abutting plates 32 abut against the heat preservation templates 1. The tie rod 2 penetrates through the heat preservation templates 1, the abutting plates 32 and the adjusting pipe 31 at the same time, and then install the tensioning assembly 33 between the two abutting plates 32;

[0060] S2: Then symmetrically install the outer support mechanism 4 on the sides of the two heat preservation templates 1 away from each other. Place the abutting strip 12 on the outside of the heat preservation templates 1, and insert the fixing rod 412 into the abutting strip 12. At the same time, the fixing ring 411 hinged to the fixing rod 412 is coaxially inserted into the tie rod 2. The reinforcing rod 42 is inserted into a plurality of parallel tie rods 2 at the same time, and one side of the reinforcing rod 42 abuts against the fixing ring 411, and the other side of the reinforcing rod 42 abuts against the nut 21. The nut 21 is threadedly connected to both ends of the tie rod 2;

[0061] S3: After the inner support mechanism 3 and the outer support mechanism 4 are installed, a casting space is formed between the two heat preservation templates 1. After the concrete slurry is cast into the casting space, the wall casting work is completed.

[0062] The above are all the preferred embodiments of the present application, and the protection scope of the present application is not limited accordingly. Therefore, all equivalent changes made according to the structure, shape and principle of the present application should be covered within the protection scope of the present application.
