[0031] Example:

[0032] Reference Figures 1-7A formwork support device for a cantilevered staggered balcony includes a wall 1 and a guide rail 3 installed on the wall 1. It also includes: a sliding block 4 slidably connected inside the guide rail 3; a lifting rod 5 fixedly connected between the bottom of the guide rail 3 and the sliding block 4; and a fastening rod 6 fixedly connected between the top of the guide rail 3 and the sliding block 4; horizontal columns 7 fixedly connected to the sliding block 4 on the side near the fastening rod 6; beams 8 fixedly connected to the sliding block 4 on the side near the lifting rod 5; a side formwork support mechanism provided on the side of the horizontal columns 7 that is close to each other, used to support the side of the balcony according to the length of the balcony side; and a positioning column 10 fixedly connected to the side of the horizontal columns 7 that is close to each other; a fastening mechanism provided on the side of the positioning column 10 near the wall 1, used to support the balcony side away from the wall 1. The support mechanism is set on the beam and column 8 and is used to support the bottom of the balcony. The first side aluminum formwork 18, the second side aluminum formwork 22 and the bottom aluminum formwork 33 are respectively set on the side near the side support mechanism, the tight formwork mechanism and the support mechanism, and are used to enclose the receiving space on the outside of the wall 1. It also includes a connecting rod 11 hinged between the telescopic part of the beam and column 8 and the telescopic part of the horizontal column 7. When the horizontal column 7 extends outward, the connecting rod 11 first rotates and then drives the telescopic part of the beam and column 8 to extend outward. It also includes a connecting column 9 fixedly connected below between the two sets of guide rails 3. Both the beam and column 8 and the connecting column 9 are telescopic structures. A second support column 25 is fixedly connected between the telescopic parts of the beam and column 8. A reinforcing rib 12 is hinged between the fixed part of the connecting column 9 and the second support column 25, and the reinforcing rib 12 is a telescopic structure.

[0033] In this embodiment, when constructing the balcony formwork, the guide rail 3 is first fixed to the side of the wall 1 near the balcony opening 2 using expansion bolts. The equipment is then adjusted to a designated height using the lifting rod 5. Subsequently, the bottom aluminum template 33 is lifted to the designated height using the support mechanism. Then, the first side aluminum template 18 and the second side aluminum template 22 are sequentially fixed to the side of the bottom aluminum template 33 using the side support mechanism and the tightening mechanism. This creates a space that matches the size of the balcony, formed by the first side aluminum template 18, the second side aluminum template 22, and the bottom aluminum template 33. It should be explained that... To ensure the airtightness of the containment space, sealant is usually applied to the joints of the first aluminum formwork 18, the second aluminum formwork 22, and the bottom aluminum formwork 33 to prevent leakage during pouring. Furthermore, before setting up the formwork, the distance between the guide rails 3 and the length of the horizontal column 7 can be adjusted according to the size of the balcony. During this process, the positions of the support points of the first aluminum formwork 18, the second aluminum formwork 22, and the bottom aluminum formwork 33 can be automatically adjusted to ensure their stability before pouring can proceed.

[0034] Reference Figure 1 , Figure 4 and Figure 5The side support mechanism includes a fixed hydraulic rod 13 fixedly connected to one side of the horizontal column 7. A first sliding sleeve 14 is slidably connected to the horizontal column 7. A first movable hydraulic rod 15 is fixedly connected to the side of the first sliding sleeve 14 near the fixed hydraulic rod 13. A first side fixing plate 17 is fixedly connected to the ends of both the fixed hydraulic rod 13 and the first movable hydraulic rod 15. A first adjusting hydraulic rod 16 is fixedly connected between the fixed hydraulic rod 13 and the first movable hydraulic rod 15 on the same side. The horizontal column 7 is a telescopic structure. The horizontal column 7 and the first adjusting hydraulic rod 16 are connected by a pipe. When the horizontal column 7 extends outward, the first adjusting hydraulic rod 16 extends outward.

[0035] In this embodiment, after the horizontal column 7 is moved to the specified height, the distance between the fixed hydraulic rod 13 and the first movable hydraulic rod 15 is adjusted according to the length of the horizontal column 7 (i.e., according to the height and width of the balcony). This adjusts the position of the fulcrum according to the width of the balcony, ensuring the stability of the first side fixed plate 17 during pouring. It should be noted that the first movable hydraulic rod 15 is at least one set, and the number of the first movable hydraulic rod 15 can be appropriately increased according to the size of the balcony. A first adjusting hydraulic rod 16 is set between adjacent first movable hydraulic rods 15.

[0036] Reference Figure 1 , Figure 3 , Figure 4 and Figure 5 The clamping mechanism includes multiple sets of second sliding sleeves 19 slidably connected to the positioning column 10. A second movable hydraulic rod 20 is fixedly connected to the side of the second sliding sleeve 19 closest to the wall 1. A second side fixing plate 21 is fixedly connected to the end of the second movable hydraulic rod 20 away from the second sliding sleeve 19. A second adjusting hydraulic rod 23 connected to the second movable hydraulic rod 20 is fixedly connected to the second sliding sleeve 19. The positioning column 10 is a telescopic structure. The positioning column 10 and the second adjusting hydraulic rod 23 are connected by a pipe. When the positioning column 10 extends outward, the second adjusting hydraulic rod 23 extends outward.

[0037] In this embodiment, when installing the guide rail 3, the positioning column 10 will extend or retract appropriately according to the length of the balcony, thereby driving the second adjusting hydraulic rod 23 to extend or retract and adjust the position of the support point of the second side aluminum template 22. It should be explained that the number of the second movable hydraulic rods 20 can be appropriately increased according to the length of the balcony, and the second movable hydraulic rod 20 at the center position of the positioning column 10 is in a fixed state. The second adjusting hydraulic rod 23 is added to the adjacent second movable hydraulic rods 20, so that the second side fixing plate 21 is evenly distributed on the side of the second side aluminum template 22.

[0038] Reference Figure 1 and Figure 4It also includes a balcony opening 2 opened on the wall 1. The dimensions between the two sets of first-side aluminum templates 18 match the dimensions of the balcony opening 2. The first-side aluminum templates 18 are perpendicular to the wall 1, and the second-side aluminum templates 22 are parallel to the wall 1. The two ends of the second-side aluminum templates 22 match the outer walls of the first-side aluminum templates 18.

[0039] In this embodiment, it should be explained that the balcony opening 2 is opened from the inside of the building to the outside. Usually, a steel cage is also set in the wall 1 to increase the quality of the balcony pouring. The pouring of the balcony mainly involves pouring the bottom of the balcony, while the side walls of the balcony can be directly installed or stacked on the bottom foundation.

[0040] Reference Figure 3 , Figure 6 and Figure 7 The support mechanism includes a first support column 24 fixedly connected between beams and columns 8. A third sliding sleeve 26 is slidably connected to the beams and columns 8. A movable column 27 is fixedly connected between the third sliding sleeves 26 on both sides. Multiple sets of fourth sliding sleeves 28 are slidably connected to both the first support column 24 and the movable column 27. A column 29 is fixedly connected to the top of the fourth sliding sleeve 28. A bottom fixing plate 30 is fixedly connected to the end of the column 29 away from the fourth sliding sleeve 28. The first support column 24 and the movable column 27 are telescopic structures. The fourth sliding sleeves 28 are slidably connected to the fixing parts of the first support column 24 and the movable column 27. The bottom fixing plate 30 is located on the same horizontal plane and is in contact with the bottom aluminum template 33. It also includes a third adjusting hydraulic rod 31 fixedly connected to the movable column 27 and the fixed part of the first support column 24. The third adjusting hydraulic rod 31 is connected to the column 29. The third adjusting hydraulic rod 31 is connected to the corresponding first support column 24 and movable column 27 through a pipe. When the first support column 24 and movable column 27 extend outward, the third adjusting hydraulic rod 31 extends outward. It also includes a supporting hydraulic rod 32 fixedly connected between the telescopic part of the first support column 24, the telescopic part of the movable column 27, and the telescopic parts of two adjacent sets of movable column 27. The supporting hydraulic rod 32 is connected to the horizontal column 7 through a pipe. When the supporting hydraulic rod 32 extends outward, the horizontal column 7 extends outward.

[0041] In this embodiment, the third adjusting hydraulic rod 31 and the supporting hydraulic rod 32 are extended or retracted according to the width and height of the balcony. It should be explained that the number of columns 29 can also be appropriately increased according to the length and width of the balcony. When there are many columns 29, the column 29 at the center position can be fixedly connected to the first supporting column 24 and the moving column 27. At the same time, the position of the columns 29 is adjusted by the third adjusting hydraulic rod 31 and the supporting hydraulic rod 32 so that the columns 29 are evenly distributed at the bottom of the bottom aluminum formwork 33. In order to improve the stability of the formwork, pressure sensors can be set on the first side fixing plate 17, the second side fixing plate 21 and the bottom fixing plate 30. This is a conventional method in the prior art, so it will not be described in detail.

[0042] Reference Figure 1 The lifting rod 5, fixed hydraulic rod 13, first movable hydraulic rod 15, second movable hydraulic rod 20 and column 29 are all electrically driven and are used to adjust the height of the equipment and to make the first side aluminum template 18, the second side aluminum template 22 and the bottom aluminum template 33 fit together.

[0043] It should be explained that the first adjusting hydraulic rod 16, the second adjusting hydraulic rod 23, the third adjusting hydraulic rod 31, and the supporting hydraulic rod 32 all include two sets of compression chambers. When the hydraulic oil in one set of compression chambers is extracted, it is in an extended state, and when the hydraulic oil in the other set of compression chambers is extracted, it is in a contracted state. This is a conventional method in the prior art, so it will not be described in detail.

[0044] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
