Description

Technical Field

[0001] This application relates to the technical field of formwork support construction, and in particular to a tall formwork support system and its construction method. Background Technology

[0002] Tall formwork supports are mainly used to bear the huge load generated by concrete pouring. They are commonly used in the construction of high-rise building floor slabs and terraces where there is a high formwork height.

[0003] Currently, scaffolding structures are typically used for supporting tall formwork, and the construction process follows the sequence of "erecting from bottom to top layer by layer, and dismantling from top to bottom layer by layer after completion." Specifically, construction workers need to start from the ground and gradually install scaffolding components such as uprights and horizontal bars upwards until the designed height is reached; after the concrete reaches the designed strength, the components are then dismantled downwards, starting from the highest point.

[0004] Regarding the aforementioned technologies, traditional tall formwork scaffolding structures require workers to perform high-altitude operations during the erection and dismantling process. On the one hand, this poses significant safety hazards; on the other hand, the overall scaffolding erection process is cumbersome and has a long construction period, resulting in low overall construction efficiency. Therefore, there is room for improvement. Summary of the Invention

[0005] To improve the construction efficiency of tall formwork support structures, this application provides a tall formwork support system and its construction method.

[0006] This application provides a tall formwork support system and its construction method, which adopts the following technical solution:

[0007] A tall formwork support system includes a support mechanism and a lifting mechanism;

[0008] The support mechanism includes a support frame;

[0009] The support frame is assembled from several scaffolding units, which are distributed vertically. Each scaffolding unit includes several uprights, and the adjacent ends of the uprights of adjacent scaffolding units are connected by connectors.

[0010] The lifting mechanism includes a lifting frame and a lifting assembly. The lifting frame is hollow inside and has an opening at the top. An inlet and outlet are provided on one side of the lifting frame for the scaffolding unit to enter and exit the lifting frame. The lifting assembly includes a plurality of lifting winches located at the top of the lifting frame. The lifting winches are used to pull and hoist the scaffolding unit.

[0011] By adopting the above technical solution, the scaffolding units of the support frame can be prefabricated and assembled in advance, eliminating the need to erect the individual components of the scaffolding units in the construction area, effectively reducing on-site work steps. When assembling the support frame, the scaffolding units can be moved in from the inlet and outlet of the hoisting frame, and then gradually lifted and lowered to the designated height from bottom to top by the hoisting winch. After the subsequent new scaffolding units are moved into place, the adjacent scaffolding units are connected by connectors, realizing the support frame erection operation from bottom to top. When dismantling the support frame, the upper scaffolding units are pulled by the lifting components, and the lower scaffolding units are dismantled from the bottom of the upper scaffolding units, realizing the support frame dismantling operation from bottom to top. Compared with the traditional construction method, the entire process of assembling and dismantling the support frame does not require construction personnel to carry out high-altitude erection and dismantling operations, effectively avoiding the safety hazards of high-altitude operations, significantly shortening the construction cycle, and improving the overall construction efficiency.

[0012] Preferably, the support mechanism further includes a base support assembly located below the support frame. The base support assembly includes several adjustable base supports, each of which includes a base. A support screw is vertically arranged on the base, and a support nut is threaded onto the support screw.

[0013] Several adjustable base supports correspond one-to-one with several uprights of the scaffolding unit. The bottom end of the upright of the scaffolding unit located at the bottom of the support frame is sleeved on the top end of the support screw corresponding to the adjustable base support.

[0014] By adopting the above technical solution, the bottom scaffolding unit of the support frame can be vertically adjusted through the adjustable base. When dismantling the scaffolding unit later, the bottom scaffolding unit can be moved downward by rotating the support nut, so that the lower scaffolding unit can be better separated from the bottom of the upper scaffolding unit.

[0015] Preferably, the lifting mechanism further includes a top support conveying assembly, which is located inside the lifting frame and below the support frame. The top support conveying assembly is used to convey the scaffolding unit of the support frame and also to assist in supporting the support frame.

[0016] The top support conveyor assembly includes several top support conveyor belts, which are horizontally arranged. The input ends of the top support conveyor belts extend out of the inlet and outlet of the lifting frame. Several lifting drive components are provided at the bottom of each top support conveyor belt, which are used to drive the top support conveyor belts to move vertically up and down.

[0017] By adopting the above technical solution, when setting up the support frame, the scaffolding units can be placed at the input ends of several top support conveyor belts, and then transported to the inner cavity of the lifting frame by the top support conveyor belts. This helps to reduce the impact of space limitations in the inner cavity of the lifting frame on the placement and movement of the scaffolding units. With the setting of the lifting drive component, on the one hand, before the scaffolding units are transported by the top support conveyor belt, the lifting drive component can be used to drive the top support conveyor belt to move the scaffolding units upward, so as to lift the scaffolding units off the ground, so as to facilitate the smooth transport of the scaffolding units by the top support conveyor belt. On the other hand, after the support frame is set up, the lifting drive component can be used to drive the top support conveyor belt to move upward and abut against the bottom of the support frame, so as to support and limit the bottom of the support frame.

[0018] Preferably, the inner cavity of the lifting frame is provided with two limiting components, which are located at the top and bottom of the lifting frame, respectively.

[0019] The limiting component includes a limiting part and a first driving member. The limiting part includes two limiting conveyor belts, which are respectively supported on opposite sides of the inner cavity of the lifting frame and are vertically arranged. The first driving member is used to drive the two limiting conveyor belts to move relative to each other.

[0020] When the hoisting winch pulls and lowers the scaffolding unit, the first driving component drives the two limiting conveyor belts to abut against both sides of the scaffolding unit, and the two limiting conveyor belts cooperate with the hoisting winch to drive the scaffolding unit to move.

[0021] By adopting the above technical solution, when the scaffolding unit is hoisted and lowered by the hoisting winch, the first drive component of the limiting assembly first drives the two vertical limiting conveyor belts to move relative to each other until they abut against both sides of the scaffolding unit. During the vertical movement of the scaffolding unit, the two limiting conveyor belts assist the scaffolding unit in smooth lifting and lowering by moving synchronously on their own. On the one hand, this helps to reduce the swaying of the scaffolding unit; on the other hand, it can limit the lateral position of the scaffolding unit, preventing the scaffolding unit from deviating during lifting or lowering and thus colliding with the inner wall of the hoisting frame, which helps to ensure that the scaffolding unit always moves along the preset trajectory.

[0022] Preferably, a temporary support assembly is also provided inside the lifting frame, the temporary support assembly including a support part and a second driving component;

[0023] The support includes two support members, which are located on opposite sides of the inner cavity of the lifting frame. The second driving member is used to drive the two support members to move relative to each other.

[0024] When the lifting assembly pulls and hoists the scaffold unit to the top of the lifting frame, the second driving member drives the two supporting members to move relative to each other to the bottom of the scaffold unit to provide temporary support for the scaffold unit.

[0025] By adopting the above technical solution, after the scaffolding unit is lifted and placed to the top of the lifting frame by the hoisting winch, the second drive component of the temporary support assembly drives the two support components to move relative to each other to the bottom of the scaffolding unit. The two oppositely arranged support components are used to lift and limit the bottom of the scaffolding unit, preventing the scaffolding unit from moving downward due to its own weight or external load, thus preventing it from affecting the subsequent movement, positioning and connection of the scaffolding unit.

[0026] Preferably, the connector includes a connecting sleeve coaxially fixed to the top of the upright, and the upright located in the upper part of the scaffold and the connecting sleeve located in the lower part of the scaffold are inserted into each other.

[0027] By adopting the above technical solution, when connecting adjacent scaffolding units, simply insert the bottom end of the upright of the upper scaffolding unit into the connecting sleeve at the top of the upright of the lower scaffolding unit to quickly achieve positioning and connection between the two, which facilitates the assembly and disassembly of adjacent scaffolding units.

[0028] Preferably, a number of lifting jacks are provided on the bottom outer side of the lifting frame, the lifting jacks are arranged vertically downwards, and the bottom end of the piston rod of each lifting jack is equipped with casters.

[0029] By adopting the above technical solution, when moving the lifting frame, the jacking jack drives the corresponding casters to move down, so that the casters touch the ground and the bottom of the lifting frame is lifted off the ground, making it easier for the lifting frame to move through the casters. After the lifting frame is moved into place, the jacking jack drives the casters to move up and retract, so that the bottom of the lifting frame contacts the ground.

[0030] A construction method for high-rise formwork support, using the aforementioned high-rise formwork support system, includes the following steps:

[0031] S1: First section of scaffolding unit moved into place: Move the scaffolding unit into the bottom of the hoist frame cavity;

[0032] S2: Scaffolding unit lifting: The scaffolding unit located at the bottom of the lifting frame is lifted to the top of the lifting frame by the lifting winch at the top of the lifting frame;

[0033] S3: Moving and positioning the ordinary section scaffolding unit: Move the scaffolding unit to the bottom of the hoist frame and align it with the upper scaffolding unit;

[0034] S4: Connection and fixing of adjacent scaffolding units: Connect and fix the adjacent ends of the uprights of the two scaffolding units at different times using connectors;

[0035] S5: Repeat steps S2 to S4 until the assembly of the support frame is completed.

[0036] By adopting the above technical solution, the scaffolding units of the support frame are assembled from bottom to top using a lifting mechanism. Compared with the traditional construction method of erecting scaffolding units layer by layer on site, there is no need to carry out high-altitude operations. This is conducive to improving the construction efficiency of the support frame while effectively avoiding the risks of high-altitude operations.

[0037] In summary, this application includes at least one of the following beneficial technical effects:

[0038] 1. Each scaffolding unit supporting the frame can be prefabricated in advance. During construction, modular assembly and dismantling operations can be carried out, effectively reducing on-site work and improving overall construction efficiency.

[0039] 2. During the erection and dismantling of the support frame, the lifting mechanism can be used to dismantle and assemble each scaffold unit layer by layer from bottom to top, eliminating the need for high-altitude operations and effectively reducing construction safety hazards.

[0040] 3. By setting the limiting component, during the process of lifting the scaffolding unit by the lifting component, the first driving component of the limiting component can drive the two limiting conveyor belts to move towards each other to clamp and limit the scaffolding unit, and assist the scaffolding unit to move vertically, effectively limiting the swaying and displacement of the scaffolding unit during the lifting process.

[0051] The following is in conjunction with the appendix Figure 1-8 This application will be described in further detail.

[0052] This application discloses a tall formwork support system and its construction method.

[0053] A tall formwork support system, referring to Figure 1 It includes a support mechanism and a lifting mechanism. The support mechanism is used to bear the load of tall formwork, and the lifting mechanism is used to assist in the erection and dismantling of the support mechanism.

[0054] Reference Figure 2 and Figure 3 The support mechanism includes a support frame 1 and a base support assembly. The support frame 1 is assembled from several scaffolding units 11, which are distributed from top to bottom. The scaffolding units 11 adopt existing modular scaffolding; each scaffolding unit 11 includes several uprights 111, several horizontal bars, and several diagonal braces.

[0055] Reference Figure 2 and Figure 4 The adjacent ends of the opposing uprights 111 of adjacent scaffolding units are connected by a connector. The connector includes a connecting sleeve 13 coaxially fixed to the top of the upright 111. The bottom end of the connecting sleeve 13 is welded and fixed to the top end of the upright 111 using a ring welding process. The bottom end of the upright 111 of the upper scaffolding unit 11 is inserted into the connecting sleeve 13 of the lower scaffolding unit 11 to achieve a stable connection between adjacent scaffolding units 11, while also facilitating the quick assembly and disassembly of adjacent scaffolding units 11.

[0056] Reference Figure 2 and Figure 3The base support assembly is located below the support frame 1 and includes several adjustable base supports 12. Each adjustable base support 12 includes a base 121, which is flat. A support screw 122 is vertically welded to the base 121, and a support nut 123 is threaded onto the support screw 122. Each adjustable base support 12 corresponds one-to-one with a number of uprights 111 of the scaffolding unit 11. The bottom end of the upright 111 of the scaffolding unit 11 located at the bottom of the support frame 1 is sleeved onto the top end of the support screw 122 of the corresponding adjustable base support 12, and the bottom end of the upright 111 overlaps with the support nut 123. By rotating the support nut 123, the vertical position of the support frame 1 can be finely adjusted. During construction, the base support assembly can be adjusted according to the actual situation to ensure that the support frame 1 is in a horizontal and stable state.

[0057] Reference Figure 1 and Figure 5 The lifting mechanism includes a lifting frame 2, a lifting component, a top support conveying component 23, a limiting component 24, and a temporary support component 25.

[0058] Reference Figure 5 and Figure 6 The hoisting frame 2 is hollow inside with an opening at the top. An inlet / outlet is located on one side of the hoisting frame 2, allowing the scaffolding unit 11 to enter and exit the cavity of the hoisting frame 2. The hoisting frame 2 adopts a metal frame structure. Several lifting jacks 211 are fixed to the bottom of the outer side of the hoisting frame 2, with the lifting jacks 211 arranged vertically downwards. The piston rods of the lifting jacks 211 are all equipped with casters 212. Specifically, the lifting jacks 211 are hydraulic jacks.

[0059] When it is necessary to move the lifting frame 2, the jack 211 drives the corresponding casters 212 to move downwards, so that the casters 212 abut against the ground. At the same time, the bottom of the lifting frame 2 is lifted off the ground, making it easier for the lifting frame 2 to move via the casters 212. After moving into position, the jack 211 drives the casters 212 to move upwards and retract, so that the bottom of the lifting frame 2 contacts the ground, ensuring the stability of the lifting frame 2.

[0060] Reference Figure 5 and Figure 6 The lifting assembly includes several lifting winches 22 mounted on the top of the lifting frame 2, with the winches 22 evenly distributed on opposite sides of the top of the lifting frame 2. The lifting winches 22 are used to assist in the traction and hoisting of the scaffolding unit 11. Specifically, the lifting winches 22 are electric winches, and the ends of the wire ropes of the lifting winches 22 are equipped with bow-shaped shackles for securely connecting to the crossbars at the top of the scaffolding unit 11.

[0061] Reference Figure 5 and Figure 6The top support conveyor assembly 23 is located below the support frame 1. The top support conveyor assembly 23 assists in conveying the scaffolding unit 11 and also assists in supporting the support frame 1. Specifically, the top support conveyor assembly 23 includes two parallel top support conveyor belts 231, which are horizontally arranged. The input ends of both top support conveyor belts 231 extend beyond the inlet and outlet of the lifting frame 2. The top support conveyor belts 231 are specifically made of metal conveyor belts with good load-bearing capacity. Several lifting drive components 232 are provided at the bottom of each top support conveyor belt 231. The lifting drive components 232 are used to drive the top support conveyor belts 231 to move vertically. Specifically, the lifting drive component 232 includes a lifting cylinder, the bottom end of which is fixed to the ground, and the top end of the piston rod of which is connected to the bottom of the top support conveyor belt 231 frame.

[0062] By extending the input end of the top support conveyor belt 231 outside the inlet and outlet of the hoisting frame 2, the scaffolding unit 11 to be assembled can be placed outside the hoisting frame 2 at the input ends of the two top support conveyor belts 231 during actual construction. The two top support conveyor belts 231 then transport it into the hoisting frame 2, which helps to avoid the situation where the scaffolding unit 11 is affected by the limited internal space of the hoisting frame 2.

[0063] Before the scaffolding unit 11 is transported by the top support conveyor belt 231, the lifting drive component 232 can be used to drive the top support conveyor belt 231 to move the scaffolding unit 11 upward, so as to lift the bottom end of the upright 111 of the scaffolding unit 11 off the ground, so as to facilitate the smooth transport of the scaffolding unit 11 by the top support conveyor belt 231. After the support frame 1 is in place, the lifting drive component 232 can also be used to drive the top support conveyor belt 231 upward and abut against the scaffolding unit 11 at the bottom of the support frame 1, so as to support and limit the support frame 1.

[0064] Reference Figure 1 and Figure 5 The inner cavity of the hoisting frame 2 is provided with two limiting components 24, which are located at the top and bottom of the inner cavity of the hoisting frame 2, respectively.

[0065] The limiting assembly 24 includes a limiting part and a first driving member 242. The limiting part includes two vertically arranged limiting conveyor belts 241, which are respectively supported on opposite sides of the inner cavity of the lifting frame 2. The first driving member 242 is used to drive the two limiting conveyor belts 241 to move relative to each other. The first driving member 242 includes two first driving cylinders, which are respectively installed on opposite outer sides of the lifting frame 2, and the piston rods of the two first driving cylinders are respectively connected to the corresponding limiting conveyor belts 241.

[0066] With the setting of the limiting component 24, when the top support conveyor component 23 moves the scaffold unit 11 into the lifting frame 2, the first drive component 242 drives the two limiting conveyor belts 241 so that the two first limiting conveyor belts 241 respectively abut against the opposite sides of the scaffold unit 11, thereby positioning the scaffold unit 11. Subsequently, when the scaffold unit 11 is vertically hoisted down by the hoisting winch 22 at the top of the lifting frame 2, the first drive component 242 drives the two limiting conveyor belts 241 to abut against the sides of the scaffold unit 11 respectively, and the two limiting conveyor belts 241 move synchronously to assist the scaffold unit 11 in smooth lifting and lowering. On the one hand, this helps to reduce the swaying of the scaffold unit 11; on the other hand, it can limit the lateral position of the scaffold unit 11, preventing the scaffold unit 11 from deviating during lifting or lowering and thus colliding with the inner wall of the lifting frame 2, ensuring that the scaffold unit 11 always moves along the preset trajectory.

[0067] Reference Figure 5 and Figure 7 The hoisting frame 2 is also equipped with a temporary support assembly 25, which includes a support part and a second drive member 252. The support part includes two support members, which are located on opposite sides of the inner cavity of the hoisting frame 2. The second drive member 252 is used to drive the two support members to move relative to each other.

[0068] The support component includes several horizontally arranged support blocks 251, which are evenly distributed on opposite sides of the limiting conveyor belt 241. The second drive component 252 includes several second drive cylinders horizontally arranged on both sides of the lifting frame 2. Each of the second drive cylinders corresponds to one of the support blocks 251 of the support component, and the piston rods of the second drive cylinders are connected to the corresponding support blocks 251.

[0069] When the lifting assembly pulls and lowers the scaffold unit 11 to the top of the lifting frame 2, the second drive member 252 drives the two support members to move relative to each other to the bottom of the scaffold unit 11, and the support block 251 of the support member abuts against the crossbar at the bottom of the scaffold unit 11 to provide temporary support for the scaffold unit 11 and limit the scaffold unit 11 from moving downward due to its own weight or external load.

[0070] A construction method for a tall formwork support system, referring to Figures 1 to 8 The above-mentioned tall formwork support system includes the following steps:

[0073] S1.2: Positioning of scaffold unit 11: The first driving member 242 drives the two limiting conveyor belts 241 to abut against both sides of the scaffold unit 11 to position the scaffold unit 11. After positioning is completed, the first driving member 242 drives the two limiting conveyor belts 241 to reset.

[0074] S2: Lifting of scaffolding unit 11: The scaffolding unit 11 located at the bottom of the lifting frame 2 is lifted and lowered to the top of the lifting frame 2 by the lifting winch 22 at the top of the lifting frame 2. The specific steps are as follows:

[0075] S2.1: Connect the cables of each hoisting winch 22 to the top horizontal bar of the scaffolding unit 11;

[0076] S2.3: Start the hoisting winch 22 and slowly lift the scaffolding unit 11 using wire ropes. During the lifting process, the first drive member 242 of the lower limiting component 24 drives two limiting conveyor belts 241 to abut against both sides of the scaffolding unit 11, and the two limiting conveyor belts 241 work together to lift the scaffolding unit 11. When the scaffolding unit 11 rises to the upper area of ​​the hoisting frame 2, the first drive member 242 of the lower limiting component 24 drives the two corresponding limiting conveyor belts 241 to reset. At the same time, the first drive member 242 of the upper limiting component 24 drives the two corresponding limiting conveyor belts 241 to abut against both sides of the scaffolding unit 11, and the two limiting conveyor belts 241 work together to lift the scaffolding unit 11 until the scaffolding unit 11 moves into place.

[0077] S2.3: Temporary support limit of scaffolding unit 11: The second drive member 252 drives the support blocks 251 of the two support members to move to the bottom of the scaffolding unit 11 to temporarily support and limit the scaffolding unit 11.

[0080] S3.2: Positioning of scaffold unit 11: The first drive unit 242 drives the two limiting conveyor belts 241 to abut against both sides of the scaffold unit 11 to position the scaffold unit 11. After positioning is completed, the first drive unit 242 drives the two limiting conveyor belts 241 to reset.

[0081] S4: Connection and fixing of adjacent scaffolding units 11: Connect and fix the adjacent ends of the two scaffolding units 11 relative to the uprights 111 using connectors. Specific steps are as follows:

[0082] S4.1: The second driving element 252 drives the support blocks 251 of the two support members to retract and return to their original positions;

[0083] S4.2: The hoisting winch 22, together with the two limiting conveyor belts 241 of the upper limiting component 24, moves the corresponding scaffolding unit 11 downward so that the bottom end of the upright 111 of the upper scaffolding unit 11 is inserted into the connecting sleeve 13 at the top end of the upright 111 of the lower scaffolding unit 11, ensuring a tight and secure connection.

[0084] S4.3: Disconnect the connection between the hoisting winch 22 cable and the corresponding scaffolding unit 11, and the first drive member 242 of the upper limit assembly 24 drives the two corresponding limit conveyor belts 241 to reset.

[0085] S5: Repeat steps S2 to S4 until the assembly of support frame 1 is completed.

[0086] When installing the final section of scaffolding unit 11, after the top support conveyor belt 231 moves the scaffolding unit 11 into place, an adjustable base support 12 is installed at the bottom end of each upright 111 of the scaffolding unit 11.

[0087] After the end scaffolding unit 11 is installed, the lifting drive 232 drives the corresponding top support conveyor belt 231 to move upward so that the top support conveyor belt 231 abuts against the bottom of the support frame 1. The first drive 242 of each limiting component 24 drives the two limiting conveyor belts 241 to abut against the two sides of the support frame 1 respectively, so as to support and limit the support frame 1.

[0088] S6: Removal of support frame 1:

[0089] S6.1: Traction limit of upper scaffolding unit 11: Connect and fix the cables of each hoisting winch 22 to the top crossbar of the second to last scaffolding unit 11 of the support frame 1; tighten the cables of each hoisting winch 22 to traction limit the support frame 1.

[0090] S6.2: Upper scaffolding unit 11 clamping and limiting: The first driving member 242 of the upper limiting component 24 drives the two limiting conveyor belts 241 to abut against both sides of the scaffolding unit 11 respectively, so as to clamp and limit the scaffolding unit 11.

[0091] S6.3: Lower scaffolding unit 11 moves downward: When dismantling the first section of scaffolding unit 11 of the support frame 1, rotate the support nut 123 of the adjustable base 12 downward; the first drive member 242 of the lower limiting component 24 drives the two limiting conveyor belts 241 to abut against both sides of the scaffolding unit 11 respectively, and the lower scaffolding unit 11 moves downward through the cooperation of the two limiting conveyor belts 241 of the lower limiting component 24;

[0092] S6.4: Transfer of lower scaffold unit 11: The first drive member 242 of the lower limiting component 24 drives the two limiting conveyor belts 241 to reset, so as to release the limitation on the lower scaffold unit 11; the two supporting conveyor belts 231 cooperate to carry the lower scaffold unit 11 out of the lifting frame 2 through the inlet and outlet.

[0093] S6.5: Release of upper scaffold limit: The first drive member 242 of the upper limit assembly 24 drives the two limit conveyor belts 241 to reset, thereby releasing the limit on the upper scaffold unit 11; the upper scaffold unit 11 is lowered into place by the cooperation of each lifting winch 22.

[0094] S6.6: Disconnect the hoisting winch 22 from the scaffolding unit 11;

[0095] S6.7: Repeat steps S6.1 to S6.6 until the support frame 1 is completely removed.

[0096] In this embodiment, the lifting mechanism is used to assemble each scaffolding unit 11 of the support frame 1 from bottom to top. Compared with the traditional construction method of erecting each component of the scaffolding unit 11 layer by layer on site, there is no need to carry out high-altitude operations, which helps to improve the construction efficiency of the support frame 1 while effectively avoiding the risks of high-altitude operations.

[0097] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
