Description

Technical Field

[0001] This invention relates to the field of bridge construction equipment technology, specifically to a temporary construction platform for hydraulic climbing formwork and its usage method. Background Technology

[0002] Hydraulic climbing formwork is mainly used in the construction of tall structures in bridge engineering, such as main towers and high piers. Please see [link / reference]. Figure 1 A current hydraulic climbing formwork 200 has three vertically spaced construction platforms 210 at its top. These platforms are primarily used for installing reinforcing bars 450 and formwork. When the concrete pouring of the current construction segment 410 of the bridge's high-rise structure 400 is completed, but the concrete strength has not yet reached the required level for the hydraulic climbing formwork 200 to lift, the installation of the reinforcing bars 450 for the next construction segment needs to be carried out at the top of the current segment 410 to ensure smooth workflow. Although the current hydraulic climbing formwork has three construction platforms at the top, it is only suitable for installing the bottom reinforcing bars 450 of the next construction segment. Figure 1 The portion indicated by the solid line representing the 450mm rebar cannot accommodate the installation of the 450mm rebar at the top of the next construction segment, such as... Figure 1 The portion indicated by the dotted line for the 450mm medium reinforcement needs to have a temporary platform installed on the top construction platform 213 as an operating platform for reinforcement installation, in order to solve the reinforcement installation problem for the next construction segment.

[0003] The temporary platform in the prior art is usually an integral steel platform 500 welded from multiple steel sections. When it is necessary to install the reinforcing bars 450 of the next construction segment, a tower crane is used to lift the integral steel platform 500 from the ground and install it on the top construction platform 213 at the top of the hydraulic climbing formwork 200. The steel sections at the bottom of the integral steel platform 500 are fixed to the top construction platform 213 of the hydraulic climbing formwork 200 by welding. One side of the integral steel platform 500 extends to the installation position of the reinforcing bars 450 of the towering structure 400 to facilitate the installation of the reinforcing bars 450 by workers. However, when the hydraulic climbing formwork 200 is used for the construction of a tall structure 400 with a certain angle of inclination, the steel bars 450 inside the tall structure 400 also have a certain angle of inclination. When the hydraulic climbing formwork 200 needs to be lifted to carry out the construction of the next construction segment after completing the construction of the current construction segment 410, some of the steel bars 450 located above the integral steel platform 500 will hinder the lifting of the hydraulic climbing formwork 200. Therefore, when using the existing integral steel platform 500, it is necessary to disconnect the connection between the integral steel platform 500 and the top construction platform 213 of the hydraulic climbing formwork 200 by cutting or other means before the hydraulic climbing formwork 200 is lifted. After the integral steel platform 500 is lifted from the top construction platform 213 of the hydraulic climbing formwork 200 to the ground by using a tower crane, the hydraulic climbing formwork 200 is lifted. With the multi-segment casting of the main tower and other tall structures, this construction method requires multiple hoisting and installation of the integral steel platform 500, as well as multiple welding, fixing, and cutting operations of the integral steel platform 500. The construction is cumbersome and inefficient. At the same time, the traditional integral steel platform 500 is usually quite heavy, and there are significant construction risks during the hoisting process. Summary of the Invention

[0004] To address the aforementioned problems, a temporary construction platform for hydraulic climbing formwork is provided. This platform eliminates the need for multiple lifting operations using tower cranes or other lifting equipment, thereby improving construction efficiency and reducing construction risks.

[0005] To achieve the above objectives, the technical solution adopted by the present invention is as follows:

[0006] A temporary construction platform for hydraulic climbing formwork includes several supporting components and at least one support plate. The supporting components are spaced apart, and each supporting component includes a vertical pole and a support beam. The vertical pole is vertically oriented, and one end of the vertical pole is used to connect to a hydraulic climbing formwork construction platform. A connecting shaft is provided on the vertical pole. One end of the support beam is provided with a sliding groove, the length direction of which is parallel to the length direction of the support beam. The support beam is slidably sleeved on the connecting shaft through the sliding groove and can rotate relative to the vertical pole under force. The support beam can rotate in a retracted position and a working position under force: when the support beam is in the retracted position, the support beam is vertical and stacked on one side of the vertical pole; when the support beam is in the working position, the support beam is horizontal. The support plate is detachably laid on the top surface of the horizontally arranged supporting beams.

[0007] Furthermore, when the support beam is in the working position, the end of the support beam away from the upright can be supported on the steel bars inside the towering structure of the bridge.

[0008] Furthermore, during the process of the support beam rotating from the recycling position to the working position, the support beam is slid to move backward away from the reinforcing bar; after the support beam rotates to the working position, it is slid again to extend horizontally towards the reinforcing bar until the end of the support beam away from the upright is supported on the reinforcing bar.

[0009] Furthermore, during the process of the support beam rotating from the working position to the recycling position, the support beam is first slid horizontally to move it away from the reinforcing bar until the overlap with the reinforcing bar is released, and then the support beam is rotated to the recycling position.

[0010] Furthermore, the top of the upright is provided with a mounting hole; the connecting shaft includes a connecting bolt and a locking nut, the connecting bolt includes a bolt head and a threaded part fixedly connected to the bolt head, the threaded part passes through the mounting hole, the locking nut is threadedly connected to the threaded part, and the locking nut and the bolt head are respectively located on opposite sides of the upright; the support beam is slidably and rotatably sleeved on the threaded part through the sliding groove, and the support beam is located between the upright and the bolt head.

[0011] Furthermore, the temporary construction platform for hydraulic climbing formwork also includes a support beam. The support member is connected to the construction platform of the hydraulic climbing formwork through the support beam. The support beam is used to be installed on the construction platform of the hydraulic climbing formwork. Several of the support members are spaced apart along the length direction of the support beam. The bottom end of the upright is welded to the support beam.

[0012] The present invention further provides a method for using the temporary construction platform for hydraulic climbing formwork, comprising the following steps:

[0013] S1, Install the temporary construction platform on the hydraulic climbing formwork: The hydraulic climbing formwork has at least two construction platforms arranged vertically, and the bottom ends of the uprights of several of the support members are installed on the top construction platform at the uppermost part of the hydraulic climbing formwork. In the initial state, the support beam is located at the retraction position.

[0014] S2, for the construction of high-rise bridge structures using hydraulic climbing formwork, after the concrete pouring of the current construction segment of the high-rise structure is completed using hydraulic climbing formwork, it is necessary to wait for the concrete strength to reach the design requirements before the hydraulic climbing formwork can be lifted. During the time period between the completion of the concrete pouring of the current construction segment and the concrete strength of the current construction segment reaching the design requirements, the reinforcement installation of the next construction segment of the high-rise structure is carried out, including the following steps:

[0015] S21. On the construction platform of the hydraulic climbing formwork, the steel bars at the bottom of the next construction segment are installed. The support beam is rotated from the retraction position to the working position. During the rotation of the support beam from the retraction position to the working position, the support beam is slid to move it backward away from the high-rise steel bars of the bridge structure. After the support beam is rotated to the working position, it is slid again to extend horizontally towards the steel bars until the end of the support beam away from the upright is supported on the installed steel bars, thus completing the lap of the support beam.

[0016] S22, After the support beams are spliced, support plates are laid on the top of several support beams to form a temporary construction platform, and the reinforcing bars located at the top of the next construction segment are tied on the temporary construction platform.

[0017] S3. After the concrete strength of the current construction segment reaches the design requirements, the support plate is first removed from the support beam. Then, the support beam is rotated to the recycling position. During the rotation of the support beam from the working position to the recycling position, the support beam is first slid horizontally to move it away from the reinforcing bar until the overlap with the reinforcing bar is released. Then, the support beam is rotated to the recycling position. Finally, the hydraulic climbing formwork is lifted to the next construction segment of the tall structure to carry out the concrete pouring of the next construction segment of the tall structure.

[0018] Further, in step S1, a support beam is first installed on the top construction platform of the hydraulic climbing formwork. The support beam is fixed to the column position of the top construction platform of the hydraulic climbing formwork. Then, the bottom of the support member is welded and fixed to the top surface of the support beam.

[0019] Furthermore, several of the support plates are fully laid on the top surface of several of the support beams and temporarily tied and fixed to the support beams with steel wire.

[0020] By adopting the above technical solution, the present invention has the following beneficial effects:

[0021] The aforementioned temporary construction platform for hydraulic climbing formwork involves installing support components on the platform provided with the hydraulic climbing formwork before construction. The support plate is then placed on the platform. When the next construction segment of the high-rise bridge structure needs rebar tying, the support beam is rotated to the working position, and then the support plate is laid on the top surface of the support beam, providing a temporary platform for workers to install the rebar for the next construction segment. Before the hydraulic climbing formwork is lifted, the support plate is removed and placed on the platform. Then, the support beam is moved backward away from the rebar until the overlap with the rebar is severed. Finally, the support beam is rotated back to the retraction position, completing the removal of the temporary construction platform for the hydraulic climbing formwork. This avoids the rebar obstructing the lifting of the hydraulic climbing formwork and does not affect its ascent. The aforementioned temporary construction platform for hydraulic climbing formwork can be installed and dismantled entirely by manpower. It does not require multiple hoisting operations using tower cranes or other lifting equipment, thus reducing the time occupied by tower cranes. It effectively solves the problem of traditional large steel construction platforms needing to be dismantled and hoisted away before the hydraulic climbing formwork is raised, which is cumbersome. This improves construction efficiency and reduces construction risks. Attached Figure Description

[0038] Please also see Figure 1 and Figure 11 This invention provides a preferred embodiment of a temporary construction platform 100 for a hydraulic climbing formwork 200. In this embodiment, the top of the hydraulic climbing formwork 200 is provided with three vertically spaced construction platforms 210, which, from bottom to top, are a bottom construction platform 211, a middle construction platform 212, and a top construction platform 213. The structure of the hydraulic climbing formwork 200 is prior art and will not be described in detail here for brevity. The temporary construction platform 100 is installed on the top construction platform 213 to provide an operating platform for workers to perform tasks such as installing the crossbeam reinforcement of the bridge and tying the main tower reinforcement.

[0039] Please see also Figures 2 to 4 The temporary construction platform 100 includes several support members 10 and at least one support plate 30. The support members 10 are spaced apart. Each support member 10 includes a vertical pole 11 and a support beam 13. The vertical pole 11 is vertically arranged, and one end of the vertical pole 11 is used to connect to the construction platform 210 of a hydraulic climbing formwork 200. In this embodiment, the temporary construction platform 100 for the hydraulic climbing formwork 200 also includes a support beam 20. The support members 10 are connected to the construction platform 210 of the hydraulic climbing formwork 200 through the support beam 20. For details, please refer to [further details]. Figure 7 and Figure 8 The support beam 20 is used to be installed on the top construction platform 213 of the hydraulic climbing formwork 200. Preferably, the support beam 20 is fixed to the column 300 position of the top construction platform 213 of the hydraulic climbing formwork 200 by welding. The bottom surface of the support beam 20 can be fixed to the construction platform 210 by welding. Several support members 10 are spaced apart along the length direction of the support beam 20, and the bottom end of the upright 11 is welded to the top surface of the support beam 20. A connecting shaft 40 is provided on the upright 11. Specifically, the top of the upright 11 is provided with a mounting hole 110. The connecting shaft 40 includes a connecting bolt 41 and a locking nut 43. The connecting bolt 41 includes a bolt head 411 and a threaded part 413 fixedly connected to the bolt head 411. The threaded part 413 passes through the mounting hole 110. The locking nut 43 is threadedly connected to the threaded part 413. The locking nut 43 and the bolt head 411 are located on opposite sides of the upright 11. The cooperation between the locking nut 43 and the bolt head 411 can prevent the connecting shaft 40 from detaching from the upright 11.

[0040] One end of the support beam 13 is provided with a groove 131. In this embodiment, the groove 131 is approximately waist-shaped, and its length direction is parallel to that of the support beam 13. The support beam 13 is slidably sleeved on the connecting shaft 40 through the groove 131 and can rotate relative to the upright 11 under force. Specifically, the support beam 13 is slidably and rotatably sleeved on the screw part 413 through the groove 131, and the support beam 13 is located between the upright 11 and the bolt head 411. When the locking nut 43 is rotated in the first direction under force, the locking nut 43 can move along the screw part 413 toward the upright 11 to abut against the upright 11, thereby clamping the support beam 13 by cooperating with the upright 11 through the bolt head 411, preventing the support beam 13 from rotating arbitrarily. When the locking nut 43 is subjected to force and rotates in a second direction opposite to the first direction, it can move along the screw portion 413 in a direction away from the upright 11 to release the support beam 13, thereby allowing the support beam 13 to rotate under the action of external force.

[0041] Please see also Figure 5 , Figure 6 , Figure 9 and Figure 10 In this embodiment, the support beam 13 can rotate in a retracted position and a working position: when the support beam 13 is in the retracted position, it is vertical and stacked on one side of the upright 11; when the support beam 13 is in the working position, it is horizontal, and the end of the support beam 13 away from the upright 11 can be supported on the reinforcing bars 450 of the bridge's elevated structure 400. In this embodiment, during the rotation of the support beam 13 from the retracted position to the working position, the support beam 13 is slid to move backward away from the reinforcing bars 450, thus moving it away from the reinforcing bars 450 inside the elevated structure 400 and preventing the reinforcing bars from obstructing the rotation of the support beam 13; after the support beam 13 rotates to the working position, it is slid again to extend horizontally towards the reinforcing bars 450 until the end of the support beam 13 away from the upright 11 is supported on the reinforcing bars 450 inside the elevated structure 400. During the rotation of the support beam 13 from the working position to the retraction position, the support beam 13 is first moved horizontally to move away from the internal steel bar 450 of the towering structure 400 until the overlap with the steel bar 450 is released, and then the support beam 13 is rotated to the retraction position.

[0042] The support plate 30 is detachably laid on the top surface of several horizontally arranged support beams 13. In this embodiment, the support plate 30 is a steel plank, and several support plates 30 are fully laid on the top surface of several support beams 13 of the support members 10, and are detachably connected to the support beams 13 by steel wire binding.

[0043] A preferred embodiment of the present invention also provides a method for using a temporary construction platform 100 for a hydraulic climbing formwork 200, comprising the following steps:

[0044] S1, Install a temporary construction platform 100 on the hydraulic climbing formwork 200: The hydraulic climbing formwork 200 has at least two construction platforms 210 arranged vertically, and the bottom ends of the uprights 11 of a number of support members 10 are installed on the top construction platform 213 at the top of the hydraulic climbing formwork 200. In the initial state, the support beam 13 is in the retracted position.

[0045] In this embodiment, in step S1, a support beam 20 is first installed on the top construction platform 213 of the hydraulic climbing formwork 200. The support beam 20 is fixed to the column 300 of the top construction platform 213 of the hydraulic climbing formwork 200 by welding. Then, the bottom of the upright 11 of the support member 10 is welded and fixed to the top surface of the support beam 20. In the initial state, the support beam 13 is in the retracted position. The locking nut 43 is rotated in the first direction, so that the locking nut 43 moves along the screw part 413 towards the upright 11, so as to clamp the support beam 13 between the bolt head 411 and the upright 11, so as to prevent the support beam 13 from shaking randomly during the operation of the hydraulic climbing formwork 200 and causing danger.

[0046] S2, the high-rise structure 400 of the bridge is constructed using hydraulic climbing formwork 200. After the concrete pouring of the current construction segment 410 of the high-rise structure 400 is completed using hydraulic climbing formwork 200, the formwork 200 can only be lifted after the concrete strength reaches the design requirements. During the time period from the completion of the concrete pouring of the current construction segment 410 of the high-rise structure 400 to the concrete strength of the current construction segment 410 reaching the design requirements, the reinforcement 450 of the next construction segment of the high-rise structure 400 is installed, including the following steps:

[0047] S21, on the construction platform 210 of the hydraulic climbing formwork 200, the steel bar 450 located at the bottom of the next construction segment is installed. The support beam 13 is rotated from the retraction position to the working position. During the rotation of the support beam 13 from the retraction position to the working position, the support beam 13 is slid and moved backward away from the steel bar 450. After the support beam 13 is rotated to the working position, the support beam 13 is slid and extended horizontally towards the steel bar 450 until the end of the support beam 13 away from the upright 11 is supported on the installed steel bar 450, thus completing the lap of the support beam 13.

[0048] In this embodiment, the towering structure 400 of the bridge is the main tower. The steel bars 450 inside the main tower include main bars 451 extending along the length of the main tower and connecting short bars 453 welded to the main bars 451. On the construction platform 210 of the hydraulic climbing formwork 200, the main bars 451 located at the bottom of the next construction segment are installed, and then the connecting short bars 453 are welded to the installed main bars 451.

[0049] In this embodiment, before rotating the support beam 13 from the retracted position to the working position, the locking nut 43 is rotated in the second direction, causing the locking nut 43 to move away from the upright 11 along the screw portion 413, thereby releasing the support beam 13 and facilitating its rotation. After the end of the support beam 13 away from the upright 11 is supported on the installed connecting short steel bar 453, the locking nut 43 is rotated in the first direction, causing the locking nut 43 to move closer to the upright 11 along the screw portion 413, thereby clamping the support beam 13 between the bolt head 411 and the upright 11, improving the stability of the support beam 13.

[0050] S22, after the overlapping of the support beams 13 is completed, support plates 30 are laid on top of the support beams 13 to form a temporary construction platform 100, and the reinforcing bars 450 located at the top of the next construction segment are tied on the temporary construction platform 100. In this embodiment, the support plates 30 are fully laid on the top surface of the support beams 13 and temporarily tied to the support beams 13 with steel wire.

[0051] In this embodiment, during the binding operation of the steel bar 450 at the top of the next construction segment, a safety rope 600 is set at the top of the main steel bar 451. During the construction process, the construction personnel wear safety belts throughout the process, and the safety belts are connected to the safety rope 600 to protect the construction personnel.

[0052] S3, after the concrete strength of the current construction segment 410 reaches the design requirements, the support plate 30 is first removed from the support beam 13, and then the support beam 13 is rotated to the retraction position. During the rotation of the support beam 13 from the working position to the retraction position, the support beam 13 is first moved backward away from the reinforcing bar 450 by horizontal sliding until the lap of the short reinforcing bar 453 connecting with the reinforcing bar 450 is released. Then the support beam 13 is rotated to the retraction position. Finally, the hydraulic climbing formwork 200 is lifted to the next construction segment of the towering structure 400 to carry out the concrete pouring of the next construction segment of the towering structure 400.

[0053] In this embodiment, before rotating the support beam 13 to the retraction position, the locking nut 43 is rotated in the second direction, causing the locking nut 43 to move away from the upright 11 along the screw portion 413, thereby releasing the support beam 13 and facilitating its rotation. After the support beam 13 is rotated to the retraction position, the locking nut 43 is rotated in the first direction, causing the locking nut 43 to move closer to the upright 11 along the screw portion 413, thereby clamping the support beam 13 between the bolt head 411 and the upright 11, preventing the support beam 13 from swaying freely. The removed support beam 13 can be placed on the construction platform 210 of the hydraulic climbing formwork 200 for lifting together with the hydraulic climbing formwork 200.

[0054] The temporary construction platform 100 used for the hydraulic climbing formwork 200 is equipped with support components 10 on the construction platform 210 of the hydraulic climbing formwork 200 before construction. The support plate 30 is then placed on the construction platform 210. When it is necessary to tie the reinforcing bars 450 of the next construction segment of the high-rise bridge structure 400, the support beam 13 is rotated to the working position, and then the support plate 30 is laid on the top surface of the support beam 13, thus providing a space for construction personnel to install the next construction segment. A temporary platform 100 for the hydraulic climbing formwork 200 is used. Before the hydraulic climbing formwork 200 is lifted, the support plate 30 is removed and placed on the construction platform 210 of the hydraulic climbing formwork 200. Then, the support beam 13 is moved backward away from the steel bar 450 until the overlap with the steel bar 450 is released. Then, the support beam 13 is rotated to the retraction position, thus completing the removal of the temporary construction platform 100 for the hydraulic climbing formwork 200. This avoids the steel bar 450 from obstructing the lifting of the hydraulic climbing formwork 200 and does not affect the climbing of the hydraulic climbing formwork 200. The temporary construction platform 100 used for the hydraulic climbing formwork 200 can be installed and dismantled entirely by manpower. It does not require multiple lifting operations using tower cranes or other lifting tools, reducing the time occupied by tower cranes. It effectively solves the problem of the traditional large steel construction platform needing to be dismantled and lifted away before the hydraulic climbing formwork 200 is lifted, which is cumbersome. This improves construction efficiency and reduces construction risks.

[0055] The temporary construction platform 100 used for the hydraulic climbing formwork 200 has a support beam 13 supported at one end by a vertical pole 11 and at the other end by the reinforcing steel bars 450 of the elevated bridge structure 400. This simplifies the structure of the temporary construction platform 100, reducing the amount of steel used. Compared to traditional bulky steel platforms, it is lighter, reducing the construction risks associated with high-altitude heavy lifting operations. Furthermore, the design of the chute 131 allows the support beam 13 to move closer to or further away from the reinforcing steel bars 450 of the elevated bridge structure 400, ensuring that the support beam 13 can smoothly connect to or disconnect from the reinforcing steel bars 450 of the elevated bridge structure 400.

[0056] The temporary construction platform 100 used in the hydraulic climbing formwork 200 has a connecting shaft 40 including a connecting bolt 41 and a locking nut 43. When the support beam 13 rotates to the working position or the retracted position, the locking nut 43 can be used to clamp the support beam 13 with the upright 11, thereby improving the stability of the support beam 13. When the locking nut 43 is rotated to move it away from the upright 11, the support beam 13 can be released, allowing it to rotate under force.

[0057] The temporary construction platform 100 used for the hydraulic climbing formwork 200 is installed by welding the support beam 20 to the column 300 of the construction platform 213 at the top of the hydraulic climbing formwork 200. Then, the bottom of the upright 11 of the support member 10 is welded and fixed to the top surface of the support beam 20. This installation method ensures that when the support member 10 is in the retracted state, it is roughly on the same vertical line as the column 300 of the hydraulic climbing formwork 200, avoiding the support member 10 from obstructing the lifting of the hydraulic climbing formwork 200. Therefore, the hydraulic climbing formwork 200 can be lifted without removing the support member 10, avoiding repeated welding and cutting operations of the temporary construction platform 100.

[0058] The above description is a detailed description of the preferred embodiments of the present invention. However, the embodiments are not intended to limit the scope of the patent application of the present invention. All equivalent changes or modifications made under the technical spirit of the present invention should fall within the patent scope covered by the present invention.
