[0001] This invention relates to the field of pier construction platform technology, and in particular to a pier construction platform with a large slope prefabricated guide beam. Background Technology

[0002] Incremental launching is a common construction method in bridge construction, mainly used for the construction of long-span bridges such as suspension bridges and cable-stayed bridges. It involves using temporary supports and launching equipment to gradually advance the main structure of the bridge, thereby achieving the bridge's crossing.

Furthermore, it avoids the inefficiency of flexible installation when constructing a single section of bridge, as many piers require extensive work. During construction, the rectangular and curved construction platform mechanisms are integrated using positioning and locking mechanisms and connecting tension adjustment mechanisms, ensuring stability and reliability. Utilizing the existing shape of the pier for installation and locking further eliminates the need for multiple embedded parts, saving construction materials. Attached Figure Description

[0027] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0028] Reference Figures 1-6 A construction platform for pier columns on a prefabricated guide beam with a large slope includes a pier column 1. Support columns 2 are provided at both ends of the top of the pier column 1. An inclined groove 3 is opened at the center of the top of the pier column 1. A rectangular construction platform mechanism 4, an arc-shaped construction platform mechanism 5, a positioning and locking mechanism 6 and a connecting tension adjustment mechanism 7 are respectively provided on the top of the pier column 1.

[0029] To enable auxiliary operations during bridge jacking construction using a construction platform, the rectangular construction platform mechanism 4 and two arc-shaped construction platform mechanisms 5 are assembled into the pier column 1 construction platform to realize the bridge jacking construction action. The rectangular construction platform mechanism 4 includes transverse steel cables 41 and longitudinal steel cables 42. Multiple transverse steel cables 41 and multiple longitudinal steel cables 42 are perpendicularly connected to each other. The gaps where multiple transverse steel cables 41 and multiple longitudinal steel cables 42 are connected are set as positioning installation slots 43. Transverse crossbars 44 are fixedly installed at both ends of multiple longitudinal steel cables 42.

[0030] Specifically, this is implemented by laying multiple transverse steel cables 41 and multiple longitudinal steel cables 42 on both sides of the inner wall of the inclined groove 3 at the top of the pier 1, so that the transverse crossbars 44 at both ends are located on both sides of the pier 1 to form a construction platform for operation.

[0031] To connect and install the rectangular construction platform, frame connecting rods 45 are fixedly installed at both ends of the horizontal crossbar 44, guardrail connecting rods 46 are fixedly installed on the arc surface of the horizontal crossbar 44, and multiple guardrail connecting rods 46 are linearly arranged around the axis of the horizontal crossbar 44. Horizontal foot pedals 47 are fixedly installed at the bottom of multiple guardrail connecting rods 46.

[0032] Specifically, this is achieved by installing a frame connecting rod 45 and a guardrail connecting rod 46 on the surface of the horizontal bar 44, so that the horizontal step pedal 47 is connected to the horizontal bar 44 and placed in a horizontal position.

[0033] To enhance the secure installation and protection of the horizontal foot pedal 47, guardrails 48 are fixedly installed at both ends of the two frame connecting rods 45. Guardrail bars 49 are fixedly installed on the arc surface of the guardrails 48 and one end surface of the horizontal foot pedal 47. Multiple guardrail bars 49 are arranged linearly around the axis of the guardrails 48. Tie rods 410 are also fixedly installed on the arc surface of both ends of the guardrails 48. Both ends of the tie rods 410 are fixedly installed on the surface of the longitudinal steel cable 42.

[0034] Specifically, a rectangular construction platform is formed by the guardrail 48, the frame connecting rod 45, the horizontal stepping board 47, and the horizontal crossbar 44, which is located on both sides of the pier 1. At the same time, the guardrail bars 49 are used for protection around the platform to prevent construction workers from falling. The tie rod 410 is used to lift one end of the rectangular construction platform to increase the tension and prevent the rectangular construction platform from tipping over.

[0035] Furthermore, a rectangular construction platform mechanism 4 is set up so that during construction, the connectors of multiple transverse steel cables 41 and multiple longitudinal steel cables 42 are vertically intersected and placed inside the inclined groove 3 at the top of the pier 1, and the rectangular construction platforms at both ends are located on both sides of the pier 1. After construction, it can also be disassembled and removed, which is highly flexible.

[0036] To set up a construction platform on the arc-shaped surface of the pier 1, the arc-shaped construction platform mechanism 5 includes a binding steel cable 51, a transverse arc-shaped steel cable 52, and a longitudinal arc-shaped steel cable 53. The surface of the binding steel cable 51 is wrapped around the support column 2. The two ends of the binding steel cable 51 are respectively fixedly installed with a connecting locking seat 54 and a connecting transition block 55. The surface of the connecting locking seat 54 is provided with a locking hole 56, and the surface of the connecting transition block 55 is provided with a transition hole 57. The inner wall of the locking hole 56 is threaded with a locking rod 58. The locking rod 58 is located on one side of the connecting transition block 55, and the arc surface of the locking rod 58 is movably sleeved with the inner wall of the transition hole 57.

[0037] Specifically, during installation, the binding steel cable 51 is used to bind and connect the support column 2, thereby laying multiple longitudinal arc-shaped steel cables 53 around the surface of the support column 2 on the arc-shaped surface of the pier 1. At the same time, multiple transverse arc-shaped steel cables 52 are used to connect and strengthen the reliability. When the binding steel cable 51 is connected, the connecting locking seats 54 at both ends contact the connecting transition block 55, pass through the locking rod 58 to make it threaded and locked. The connecting locking seats 54 are controlled to squeeze the connecting transition block 55, thereby controlling the binding steel cable 51 to be locked on the surface of the support column 2.

[0038] In order to connect the arc-shaped construction platform and the rectangular construction platform into a whole, one end of each of the multiple longitudinal arc-shaped steel cables 53 is fixedly connected to the surface of the binding steel cable 51, and multiple transverse arc-shaped steel cables 52 are perpendicularly connected to the surface of the multiple longitudinal arc-shaped steel cables 53. Arc-shaped crossbars 59 are fixedly installed at the bottom of each of the multiple longitudinal arc-shaped steel cables 53, and connecting frames 510 are fixedly installed at both ends of the arc-shaped crossbars 59. One side surface of the connecting frame 510 is connected to the surface of the frame connecting rod 45 by screw threads.

[0039] Specifically, connecting frames 510 are set on both sides of the arc-shaped construction platform, thereby controlling one side surface of the connecting frame 510 to be connected to the opposite surface of the rectangular construction platform by screw threads to form an integral whole, thus forming an integral construction platform on the four sides of the pier 1, which facilitates the bridge jacking construction operation.

[0040] Vertical connecting rods 511 are fixedly installed on the arc surface of the arc-shaped crossbar 59. Multiple vertical connecting rods 511 are linearly arranged around the arc axis of the arc-shaped crossbar 59. Arc-shaped foot pedals 512 are fixedly installed at the bottom of multiple vertical connecting rods 511. Arc-shaped guardrail 513 is fixedly installed at one end of the connecting frame 510.

[0041] Specifically, in the operation of the arc-shaped construction platform, multiple vertical connecting rods 511 are used to control the arc-shaped horizontal bar 59 and the arc-shaped foot pedal 512 to connect the whole, forming an arc-shaped construction platform with the arc-shaped guardrail 513.

[0042] Vertical guardrails 514 are fixedly installed on the surface of the curved guardrail 513 and the top of one end of the curved foot pedal 512. Multiple vertical guardrails 514 are linearly arranged around the curved axis of the curved guardrail 513. Reinforcing connecting rods 515 are also fixedly installed on the arc surface of the curved guardrail 513. The tops of multiple reinforcing connecting rods 515 are fixedly installed on the surface of multiple longitudinal curved steel cables 53.

[0043] Specifically, during construction, multiple reinforcing connecting rods 515 on the surface are used to ensure a secure connection on one side of the curved construction platform, preventing it from tipping over during construction. Multiple vertical guardrails 514 are used to protect the curved perimeter to prevent personnel from falling during construction, thus enhancing the safety of the construction.

[0044] In order to realize the action of locking the rectangular construction platform mechanism 4 inside the inclined groove 3, the positioning and locking mechanism 6 includes positioning blocks 61. Multiple positioning blocks 61 are fixedly installed in the middle of the inner bottom wall of the inclined groove 3. The surface of the positioning blocks 61 is slidably inserted into the inner wall of the positioning installation groove 43. The top of each of the four positioning blocks 61 is connected to a U-shaped pressure plate 62 by screw threads. The bottom of the U-shaped pressure plate 62 is in contact with the surface of multiple transverse steel cables 41 and the surface of multiple longitudinal steel cables 42.

[0045] Specifically, the rectangular construction platform mechanism 4 is controlled by the positioning and locking mechanism 6 for installation, locking, and positioning. During installation, the positioning installation slot 43 is inserted into the surface of the positioning block 61. The U-shaped pressure plate 62 is taken out and squeezed against the surface of the transverse steel cable 41 and the longitudinal steel cable 42. The two ends are placed on the top of the positioning block 61 and connected by screws. After the pier 1 is installed, it can be disassembled and taken to the top of another pier 1 for installation and use, which enhances flexibility.

[0046] The connecting tension adjustment mechanism 7 realizes the action of adjusting the installation position of the two arc-shaped construction platform mechanisms 5 to balance the gravity. The connecting tension adjustment mechanism 7 includes a pull head 71, and the two pull heads 71 ​​are arranged opposite to each other inside the two arc-shaped construction platform mechanisms 5 and are movably sleeved with the arc surface of the locking rod 58. One end of the locking rod 58 is also threadedly connected to a locking block 72. The two locking blocks 72 press against each other. The two ends of the two pull heads 71 ​​are respectively fixedly installed with a left adjusting rod 73 and a right adjusting rod 74. The surface of the left adjusting rod 73 is provided with a left-hand thread, and the surface of the right adjusting rod 74 is provided with a right-hand thread. The inner wall of the left-hand thread and the inner wall of the right-hand thread are both threadedly connected to an adjusting tube 75. The two ends of the adjusting tube 75 are provided with limit blocks 76, and the two limit blocks 76 are threadedly connected to the left adjusting rod 73 and the right adjusting rod 74 respectively.

[0047] Specifically, during construction, the connecting tension adjustment mechanism 7 controls the connection of the arc-shaped construction platform mechanism 5 at both ends to form a whole. The weight of the construction platform is counteracted by the two support columns 2, thereby dispersing its weight and preventing it from falling and being damaged due to excessive weight. During the connection, the adjustment tube 75 is rotated to control the left adjustment rod 73 and the right adjustment rod 74 at both ends to move towards each other and tighten.

[0048] By setting a rectangular construction platform mechanism 4 and an arc-shaped construction platform mechanism 5 on the top of pier 1, an integrated construction platform is formed around the top of pier 1. This construction platform is highly flexible, can be installed and operated during use, and can be disassembled when not in use. This avoids the problems associated with setting many embedded parts on the top of pier 1, which leads to complicated post-processing, high processing costs, and a certain impact on the appearance quality of the pier body. Furthermore, installation and disassembly are inconvenient, and many pier 1 construction operations are required when constructing a whole section of the bridge, making flexible installation and use impossible and inefficient. During construction, the positioning and locking mechanism 6 and the connecting tension adjustment mechanism 7 are used to control the rectangular construction platform mechanism 4 and the arc-shaped construction platform mechanism 5 to form an integral whole, making it reliable and stable. The existing shape of pier 1 is used for installation, locking, and support, further avoiding the effect of setting multiple embedded parts and saving construction materials.

[0049] Working principle: During the bridge construction jacking process, the rectangular construction platform mechanism 4 is first controlled by the lifting equipment to reach the top of the pier 1. The connectors of the transverse steel cable 41 and the longitudinal steel cable 42 are placed above the inclined groove 3, so that the positioning installation groove 43 is inserted into the positioning block 61. At the same time, the construction platforms at both ends are symmetrically installed and placed horizontally. After the rectangular construction platform mechanism 4 is installed.

[0050] Using lifting equipment to control the arc-shaped construction platform mechanism 5, the binding steel cable 51 is bound around the support column 2, and the connectors that make the transverse arc-shaped steel cable 52 and the longitudinal arc-shaped steel cable 53 vertically connected are laid on the arc-shaped surface at the top of the pier 1, controlling the arc-shaped construction platform to be placed vertically. After the arc-shaped construction platform mechanisms 5 on both sides of the pier 1 are installed, the left adjustment rod 73 and the right adjustment rod 74 at both ends are controlled by the connecting tension adjustment mechanism 7 to move towards each other, driving the two arc-shaped construction platform mechanisms 5 at both ends to move closer together, so that their vertical gravity is balanced, and the rectangular construction platform mechanism 4 and the arc-shaped construction platform mechanism 5 are connected into a whole by the control connecting frame 510.

[0051] The above are merely preferred embodiments 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.
