The present application will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0031] It should be noted that, in order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the present invention is further described in detail below with reference to the accompanying drawings and specific embodiments.

[0032] Depend on Figure 1 The adjustable support frame for building formwork shown in the figure includes a base 1, and hydraulic components are fixedly connected to both sides of the base 1. The hydraulic components are rotatably connected to a bracket 2 and a support plate 3 respectively connected to the top surface of the base 1 for limited rotation. The top surface of the support plate 3 is slidably connected to a bidirectional movable component. The top surface of the movable component is fixedly connected to a first support component for lifting the building formwork, and a second support component is provided on the top surface of the first support component, and the second support component is rotatably connected to the top of the bracket 2; the first support component and the second support component are connected through a gear 12. The top surface of the first support component and the top surface of the second support component are respectively provided with a plurality of first sliding holes, and the top surface of the second support component is slidably connected to a plurality of support bars 4, and the top surface of the support bars 4 is provided with second sliding holes corresponding to the first sliding holes; the second sliding hole is connected to a vibration component for exciting a skeleton 5 of reinforced concrete, and the vibration component is fixedly connected to the building formwork and the skeleton 5 respectively. A vibrator connected to an external excitation device is provided in the vibration component, which can transmit vibration to the skeleton through the vibration component. It is a prior art and will not be described in detail here. The same side of the bracket 2 and the support plate 3 is fixedly connected with a limiting plate 33 , and one side surface of the two limiting plates 33 abuts against the bracket 2 and the support plate 3 , respectively.

[0033] In the present invention, the first support assembly and the second support assembly are lifted by using a hydraulic component, which can not only adjust the heights of the first support assembly and the second support assembly to facilitate the support of the formwork, but also facilitate the direct laying of the formwork on the first support assembly and the second support assembly, thus facilitating the installation of the formwork. During the process, the first support assembly and the second support assembly can slide in the opposite direction, increasing the support range of the present support frame and reducing the occupied area under the skeleton of the concrete. The vibration component arranged on the support bar 4 can utilize the large-area laying of the skeleton to expand the range and uniformity of the vibration of the concrete, improving the working efficiency.

[0034] As Figures 2-3 shown, the first support assembly includes a first slide plate 6, and a number of first slide holes are opened on the top surface of the first slide plate 6. The bottom surface of the first slide plate 6 is fixedly connected to the moving component. An installation groove 7 is opened in the middle of the top surface of the first slide plate 6. A support block 8 is slidably connected in the installation groove 7. A spring 9 is fixedly connected between the bottom surface of the support block 8 and the bottom surface of the installation groove 7. One end of the support block 8 close to the second support assembly is chamfered, so that when the second slide plate 17 moves in the opposite direction to the first slide plate 6, the second slide plate 17 can push the support block 8 downward to make way through the chamfer, realizing the smooth movement of the second slide plate 17 and the first slide plate 6. The top surface of the support block 8 and one end of the first slide plate 6 are respectively abutted against the bottom surface of the support bar 4, increasing the support points of the support bar 4 and thus enhancing the supporting force of the support bar 4. Through holes 10 are opened in the opposite side surfaces of the first slide plate 6. One end of the through hole 10 is adapted to and slidably connected to a supporting block 25. The other end of the through hole 10 is slidably connected to a pull plate 11. The end of the pull plate 11 extending out of the through hole 10 is fixedly connected to the second support assembly. The supporting block 25 is fixedly connected to the pull plate 11. Through the fixed connection of the pull plate 11 with the second slide plate 17 of the support bar 4, when the second slide plate 17 moves in the opposite direction to the first slide plate 6, the pull plate 11 can push the support block 8 into the through hole 10 to avoid interference between the supporting block 25 and the support block 8. A first rack 37 is fixedly connected to one side surface of the first slide plate 6. The first slide plate 6 is meshed with a gear 12 through the first rack 37.

[0035] Further, the moving component includes a T-shaped block 35 and a rotating shaft 36. A T-shaped groove is opened on the top surface of the support plate 3. The T-shaped block 35 is adapted to and slidably connected to the T-shaped groove. Two oppositely arranged support blocks are fixedly connected to the top surface of the T-shaped block 35. The two ends of the rotating shaft 36 are respectively rotatably connected to the two support blocks. The outer side surface of the rotating shaft 36 is fixedly connected to the bottom surface of the first slide plate 6, which can not only realize the sliding of the T-shaped block 35 in the T-shaped groove, but also realize the rotation of the first slide plate 6 around the rotating shaft 36.

[0036] For a further optimized solution, the second support assembly includes a bracket 13. The bottom surface of the bracket 13 is rotatably connected to the top surface of the support 2. A first chute 15 is provided on the side surface at the top end of the bracket 13. A slider 14 is slidably connected in the first chute 15. A driving member 16 is fixedly connected to the side surface of the slider 14, and the driving member 16 is fixedly installed in the first chute 15. A second slide plate 17 is fixedly connected to one side surface of the slider 14. A second chute for slidably connecting with the support bar 4 is provided on the top surface of the second slide plate 17, and a number of first slide holes are provided on the bottom surface of the second chute; the bottom surface of the second slide plate 17 is fixedly connected to one end of the pull plate 11; a gear 12 is rotatably connected to the bottom end of the bracket 13. A second rack is provided on one side surface of the second slide plate 17, and the second slide plate 17 is engaged with the gear 12 through the second rack; the bottom surface of the second slide plate 17 is slidably connected to the top surface of the first slide plate 6.

[0037] Furthermore, a number of pointed protrusions are provided on the top surface of the support bar 4, which is convenient for increasing the friction between the support bar 4 and the bottom surface of the formwork, so as to realize that the support bar 4 does not move when the second slide plate 17 is adjusted.

[0038] Furthermore, the driving member 16 is a conventional electric cylinder or hydraulic cylinder, which can realize pulling the slider 14 to expand and contract in the first chute 15. It is prior art and will not be elaborated here.

[0039] Furthermore, the first rack 37 and the second rack adopt a conventional transmission method, which is prior art and will not be elaborated here. The second rack is not shown in the figure.

[0040] As Figures 4-6 shown, the vibration assembly includes a closed ring 18. The closed ring 18 is embedded in the building formwork. A vibration cylinder 19 is slidably connected in the inner cavity of the closed ring 18. The top surface of the vibration cylinder 19 is closed. The vibration cylinder 19 is fixedly connected to an oscillator communicated with an external vibration excitation device. The inner cavity of the closed ring 18 is communicated with the second slide hole. A cross beam 20 is fixedly connected to the top end of the vibration cylinder 19. Auxiliary vibration assemblies are respectively rotatably connected to both ends of the cross beam 20. The auxiliary vibration assemblies are slidably connected to the side surface of the vibration cylinder 19. A fixed ring 21 is sleeved outside the auxiliary vibration assemblies, and the fixed ring 21 is fixedly connected to the framework 5. A card slot 34 adapted to the cross beam 20 and the auxiliary vibration assemblies is provided on the top surface of the closed ring 18, which is convenient for the vibration cylinder 19 excited by vibration to fit with the closed ring 18, avoiding the vibration cylinder 19 being cast into the concrete.

[0041] For a further optimized solution, the auxiliary vibration component includes a rolling wheel 22 and two guide plates 23. The rolling wheel 22 is hollow. A hollow tooth-pulling ring 24 is fixedly connected to the inner cavity side wall of the rolling wheel 22. One end of the tooth-pulling ring 24 is rotatably connected to one end of the cross beam 20. A number of tooth pullers are circumferentially and equidistantly arranged on the inner cavity side wall of the tooth-pulling ring 24. An elastic piece 26 is arranged in the inner cavity of the rolling wheel 22. The elastic piece 26 is made of spring steel and can elastically bounce and switch between different tooth pullers. A fixing rod 27 is fixedly connected to the middle of the elastic piece 26, and the fixing rod 27 is fixedly connected to one end face of the cross beam 20. The two ends of the elastic piece 26 are respectively detachably connected to a corresponding tooth puller. A fixing disc 28 is fixedly connected to the end face of the tooth-pulling ring 24 far from the cross beam 20, and the periphery of the fixing disc 28 is detachably connected to the inner cavity of the rolling wheel 22. Preferably, the periphery of the fixing disc 28 is screwed to the inner cavity side wall of the rolling wheel 22. On one side of each of the two ends of the elastic piece 26, a limiting block 29 is symmetrically arranged about the center line of the fixing rod 27. One end of the limiting block 29 is fixedly connected to the side of the fixing rod 27, and the other end is slidably connected to the inner cavity side wall of the tooth-pulling ring 24. The limiting block 29 can limit the two-way elastic movement of the elastic piece 26 and can only bend towards the side away from the limiting block 29. The top surface of the guide plate 23 is inclined, and the two guide plates 23 are symmetrically arranged about the axis of the vibration cylinder 19. A gap is arranged between the facing sides of the two guide plates 23, and the gap can be adapted to the diameter of the rolling wheel 22 to facilitate the downward movement of the auxiliary vibration component through the gap. A number of arc-shaped guide grooves 30 are arranged on the top surface of the guide plate 23. The guide grooves 30 are adapted to the rolling wheel 22 and can limit the movement of the auxiliary vibration component when the vibrator is not operating. The side surface of the guide plate 23 is fixedly connected to the inner side surface of the fixing ring 21.

[0042] Further, the gap between the facing sides of the two guide plates 23 is arranged opposite to the card slot 34, which is convenient for the auxiliary vibration component to be adapted to and engaged with the card slot 34.

[0043] For a further optimized solution, the hydraulic component includes a connecting plate 31 rotatably connected to the opposite side surfaces of the support 2 and the support plate 3 respectively. A hydraulic cylinder 32 is rotatably connected to the side surface of the connecting plate 31. One end of the hydraulic cylinder 32 is rotatably connected to the side surface of the base 1. The bottom end of the hydraulic cylinder 32 is inclined towards the end of the base 1 far from the support 2.

[0044] A supporting method for an adjustable support frame of a building formwork includes the following steps:

[0045] S1. Equipment layout: Move this support frame to the target position.

[0046] Using a transfer tool, move this support frame to the position where formwork needs to be lapped on the skeleton.

[0047] S2. Layout of formwork: Lower the first support component and the second support component by using the hydraulic components, place a number of formworks on the top surface of the second support component, and raise the first support component and the second support component until the formwork is close to the skeleton 5.

[0048] Start the hydraulic cylinder 32. By pulling the connecting plate 31, the bracket 2 and the support plate 3 are respectively pulled away from the limiting plate 33. Since the top surface of the bracket 2 is flush with the bottom surface of the first slide plate 6, the second slide plate 17 will lower its lifting height, facilitating the laying of formwork on its top surface. Before laying the formwork, by starting the driving member 16, the slider 14 is pushed to move in the first chute 15, thereby driving the second slide plate 17 fixedly connected to the slider 14 to move. Since the second slide plate 17 and the first slide plate 6 are in meshing transmission through the gear 12, the first slide plate 6 will move in the opposite direction of the second slide plate 17. During the movement of the first slide plate 6, the supporting block 8 provided on the top surface of the first slide plate 6 will be released from the suppression of the second slide plate 17 and will be ejected under the elastic force of the spring 9 and will abut against the bottom surface of the support bar 4. At the same time, the movement of the second slide plate 17 will drive the pull plate 11 to pull the supporting block 25 into the installation groove 7 and abut against the bottom surface of the supporting block 8, realizing the support of the supporting block 8 and avoiding the increase in deflection and the weakening of the supporting force at both ends of the support bar 4 due to the influence of gravity and the pressure of the formwork.

[0049] S3. Placement of the vibration component: Place the bottom end of the vibration component on the formwork, and the top end of the vibration component is fixedly connected to the skeleton 5.

[0050] The closed ring 18 is fixedly installed on the formwork, and the vibrating cylinder 19 is slidably connected to the closed ring 18. The fixed ring 21 is welded to the skeleton 5, which is convenient for being cast integrally with the concrete later, increasing the strength of the concrete skeleton. The guide plate 23 is fixedly connected to the inner wall of the fixed ring 21, and the top surface of the guide plate 23 is inclined, which can facilitate the rolling wheel 22 to move along the inclined surface and then slide into the card slot 34 through the gap between the two guide plates 23. The rolling wheel 22 is arranged in the guide groove 30, and further, in order to improve the frictional driving force between the rolling wheel 22 and the guide groove 30, a rubber layer is coated on the outer surface of the rolling wheel 22.

[0051] S4. Support the formwork: Fix the positions of all components at the current angle, connect the auxiliary vibration component to the external excitation device, and realize the resonance of the skeleton 5 through the conduction of vibration energy.

[0052] When everything is ready, concrete is poured on the top surface of the formwork. When a certain amount of concrete is poured, the external vibration equipment is started, the vibrator vibrates, and drives the vibration cylinder 19 to vibrate. The vibration cylinder 19 transmits the vibration to the guide plate 23, and the guide plate 23 transmits the vibration to the fixed ring 21, and then transmits the vibration to the entire steel skeleton 5. Through the overall vibration of the skeleton 5, the covering concrete is vibrated at the same time, which not only expands the range and uniformity of the concrete excitation, but also improves the work efficiency. During the vibration process of the vibrator, the vibration cylinder 19 transmits the vibration to the rolling wheels 22 at both ends of the vibration cylinder 19 through the crossbeam 20. Under high-speed vibration, the rolling wheels 22 continuously rub against the guide groove 30, causing the rolling wheels 22 to rotate. At the same time, the toothed ring 24 inside the rolling wheel 22 rotates accordingly, and then shifts the spring piece 26. The spring piece 26 continuously switches the teeth engaged at both ends, causing the rolling wheel 22 to enter the gap between the two guide plates 23 along the inclined surface of the guide plate 23. At this time, the excitation is stopped, and the auxiliary vibration assembly moves downward under the action of gravity. The vibration cylinder 19 passes through the first sliding hole and the second sliding hole respectively until the auxiliary vibration assembly and the crossbeam 20 are engaged in the card slot 34, thereby achieving complete sealing of the closed ring 18 to prevent concrete from invading the closed ring 18 and causing leakage.

[0053] The above are merely preferred embodiments of the present application, but the scope of protection of the present application is not limited thereto. Any changes or substitutions that can be easily conceived by a person skilled in the art within the technical scope disclosed in this application should be included in the scope of protection of the present application. Therefore, the scope of protection of the present application should be based on the scope of protection of the claims.
