Description

Technical Field

[0001] This invention relates to the field of suspension bridge anchorage technology, and more specifically, to a suspension bridge anchorage top plate installation device and method. Background Technology

[0002] Anchorages in suspension bridges are devices that secure and traction the steel cables on a bridge, allowing the cables to connect and support the bridge.

[0003] Existing suspension bridge anchorages are prefabricated before construction, facilitating transportation and adaptation to geographical locations. However, the existing gravity anchorage front anchor chamber top cover requires in-situ casting of supports for the front anchor chamber due to prefabrication and hoisting. In addition, the anchor chamber is generally high and the structure is complex, making the erection of supports more difficult and risky. Dismantling the supports after casting is also difficult. Furthermore, since the cable strands are also located inside the chamber, dismantling the supports can easily damage them. Therefore, the in-situ casting method of supports has the disadvantages of construction risks and low construction efficiency. Summary of the Invention

[0004] The purpose of this invention is to provide a device and method for installing the top plate of a suspension bridge anchorage, which solves the problem that the installation of the top cover of the front anchorage chamber of a gravity anchorage requires the casting of a large number of supports, which leads to greater construction difficulty and risk, and is also inconvenient to dismantle, making the construction cumbersome and troublesome.

[0005] The embodiments of the present invention are achieved through the following technical solutions:

[0006] This invention provides a suspension bridge anchorage top plate installation device, including a main body, a front anchorage chamber provided on the inner wall of the middle part of the main body, a top cover provided on the top of the front anchorage chamber, a top beam provided at the bottom of the top cover, support brackets provided on both sides of the inner wall of the front anchorage chamber near the top, connecting side walls provided on both sides of the top cover, an installation groove provided on the top of the support bracket, and a correction component provided in the installation groove. The correction component swings along the axis under pressure.

[0007] Preferably, the straightening assembly includes a straightening block, a pressing block, a fitting groove, a stop block, a hinge shaft, and a pressing block. The straightening block is located in the middle of the mounting groove, the pressing block is located at the bottom of the straightening block, the fitting groove is located on one side of the straightening block, the stop block is connected to the middle of the fitting groove, the hinge shaft is located at both ends of the top of the stop block, and the pressing block is connected to the top of the hinge shaft.

[0008] Preferably, the bottom of the straightening block and the pressure block are connected to one end of the mounting groove via a hinge shaft.

[0009] Preferably, the pressure block mates with the mounting groove, and the bottom of the pressure block is connected to the groove in the middle of the mounting groove by a spring.

[0010] Preferably, the abutment and the fitting groove are engaged, and the top of the abutment is connected to the fitting groove via a hinge shaft, with only one end of the hinge shaft away from the abutment connected to the fitting groove.

[0011] Preferably, the extrusion block is a square block whose bottom is connected to one side of the hinge shaft by a spring, and one side of the extrusion block is an inclined surface.

[0012] Preferably, the fitting groove includes a defining block disposed at the top of the fitting groove.

[0013] Preferably, the limiting block is an inclined triangular protrusion, and the inclined surface of the limiting block fits and cooperates with the inclined surface of the abutment block.

[0014] Preferably, the installation method of a suspension bridge anchorage top plate installation device includes the following steps;

[0015] The first step is to assemble the prefabricated main body, and then prefabricate and pour the top cover and top beam in advance;

[0016] The second step is to cast supporting brackets on both sides of the inner wall of the front anchor chamber near the top after the main body is built.

[0017] The third step is to hoist and transport the prefabricated top cover and top beam after the supporting bracket is cast in place, and place them directly onto the supporting bracket through the top beam, thereby completing the placement of the top cover and the closure of the front anchor chamber.

[0018] The fourth step is to connect the top cover with the side walls by casting on both sides of the top cover, so that the top cover will form a whole with the two sides of the front anchor chamber through the connecting side walls.

[0019] In the third step, when the top beam is placed on the top cover, it will be lifted from below and pressed against the straightening component. The inclined surface of the straightening component and its axial deflection and closing under pressure will apply pressure to the suspended top cover, straightening it towards the center. This ensures that the top cover is placed accurately and avoids the need for later relocation.

[0020] The technical solutions of the embodiments of the present invention have at least the following advantages and beneficial effects:

[0021] 1. The supporting brackets and connecting sidewalls in this device can reduce the need for brackets to be erected for the top cover before connecting to the front anchor chamber, while also allowing the top cover to be integrally connected with the front anchor chamber during prefabrication and installation, thus increasing stability.

[0022] 2. The device is also equipped with a correction component, which can apply pressure to the top cover when it is installed from below, so as to avoid the top cover being moved and adjusted repeatedly during installation. Attached Figure Description

Detailed Implementation

[0032] In the description of this invention, it should also be noted that, unless otherwise explicitly specified and limited, the terms "set," "install," "connect," and "link" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0033] The following is combined with Figures 1 to 7 The present invention will be described in detail below.

[0034] An anchorage top plate installation device for a suspension bridge includes a main body 1. A front anchorage chamber 101 is provided on the inner wall of the middle part of the main body 1. A top cover 102 is provided on the top of the front anchorage chamber 101. A top beam 1021 is provided at the bottom of the top cover 102. Support brackets 104 are provided on both sides of the inner wall of the front anchorage chamber 101 near the top. Connecting sidewalls 103 are provided on both sides of the top cover 102. An installation groove 1041 is provided on the top of the support brackets 104. A correction component is provided in the installation groove 1041. The correction component swings along the axis under pressure.

[0035] First, after the main body 1 is assembled, a front anchor chamber 101 is reserved. Then, the top cover 102 is prefabricated. At the same time, several top beams 1021 are connected to the bottom of the top cover 102. After the main body 1 is assembled, support brackets 104 are cast in place on both sides of the inner wall of the front anchor chamber 101 near the top. The top cover 102 is then hoisted onto the front anchor chamber 101 for installation. The top beams 1021 will abut against the support brackets 104 to bear the load. After the top cover 102 is placed, side walls 103 are cast in place on both sides. By connecting the side walls 103, the top cover 102 and the side wall of the front anchor chamber 101 are integrated, which increases the stability of the top cover 102. At the same time, it can reduce the construction steps of the bottom support of the top cover 102 and can be directly connected as a whole.

[0036] Furthermore, the corrective assembly includes a corrective block 105, a pressure block 1051, a fitting groove 1052, a stop block 1053, a hinge shaft 1054, and a pressing block 1055. The corrective block 105 is disposed in the middle of the mounting groove 1041, the pressure block 1051 is disposed at the bottom of the corrective block 105, the fitting groove 1052 is disposed on one side of the corrective block 105, the stop block 1053 is connected to the middle of the fitting groove 1052, the hinge shaft 1054 is disposed at both ends of the top of the stop block 1053, the pressing block 1055 is connected to the top of the hinge shaft 1054, and the bottom of the corrective block 105 is connected to the pressure block 1051. The pressure block 1051 is connected to one end of the mounting groove 1041 via a hinge shaft. The pressure block 1051 cooperates with the mounting groove 1041, and the bottom of the pressure block 1051 is connected to the groove in the middle of the mounting groove 1041 via a spring. The abutment block 1053 cooperates with the fitting groove 1052, and the top of the abutment block 1053 is connected to the fitting groove 1052 via a hinge shaft 1054. Only the end of the hinge shaft 1054 away from the abutment block 1053 is connected to the fitting groove 1052. The pressing block 1055 is a square block whose bottom is connected to one side of the hinge shaft 1054 via a spring, and one side of the pressing block 1055 is an inclined surface.

[0037] When the top cover 102 is hoisted and placed, the bottom top beam 1021 first abuts against the abutment block 1053 in the fitting groove 1052 on one side of the straightening block 105. Due to the inclined setting of the abutment block 1053, the top beam 1021 will slide and move closer along the center of the abutment block 1053, thereby enabling the top beam 1021 to be initially straightened. However, the top beam 1021 is easily swayed and corrected because it is suspended by hoisting.

[0038] The entire straightening block 105 is connected to the installation groove 1041 reserved during the casting of the supporting bracket 104 via the hinge shaft 1054. At the same time, the pressure block 1051 at the bottom of the straightening block 105 is connected to the groove in the installation groove 1041 via a spring, so that the entire straightening block 105 will deflect outward, increasing the center width, so that the top beam 1021 can enter between the two abutment blocks 1053 for contact and correction even when there is a certain deviation.

[0039] When the top beam 1021 is initially corrected by the abutment block 1053 and then placed downwards, pressure is applied to the abutment block 1053, causing the entire correction block 105 to reset and deflect. When the correction block 105 resets and closes, it will further actively apply pressure to correct the top beam 1021, allowing it to move and correct towards the center. As the top beam 1021 moves downwards, its weight will continuously force the correction block 105 to reset and close until the pressure block 1051 is completely fitted into the mounting groove 1041, so that the correction block 105 is placed vertically and fits against both sides of the top beam 1021, making it completely fit into the gap between the sides of the top beam 1021 and the top cover 102.

[0040] Furthermore, the fitting groove 1052 includes a limiting block 10521, which is disposed on the top of the fitting groove 1052. The limiting block 10521 is an inclined triangular protrusion, and the inclined surface of the limiting block 10521 fits and cooperates with the inclined surface of the abutment block 1053.

[0041] When the top beam 1021 is straightened and the straightening block 105 actively deflects and applies pressure, the abutment block 1053, due to space constraints, will be pressed and deflected into the fitting groove 1052 via the hinge shaft 1054. Simultaneously, a limiting block 10521 is provided at the top of the hinge shaft 1054, and the inclined surface of the limiting block 10521 abuts against the inclined surface of the pressing block 1055 to limit its movement. This prevents the abutment block 1053 from easily contracting when the top beam 1021 initially abuts against it, allowing for further correction. During the initial correction, only when the correcting block 105 is reset and the abutment block 1053 is pressed will the hinge shaft 1054 be forced to rotate. The inclined surface of the limiting block 10521 will press against the inclined surface of the pressing block 1055, causing the limiting block 10521 to retract into the groove. This allows the abutment block 1053 to retract, allowing the correcting block 105 to completely fit against both sides of the top beam 1021. At the same time, the pressing block 1055 will also be deflected by the retraction of the abutment block 1053 and will be positioned in the fitting groove 1052 without protruding and affecting the fit.

[0042] Furthermore, a method for installing a suspension bridge anchorage top plate mounting device includes the following steps;

[0043] The first step is to assemble the prefabricated main body 1, and then prefabricate and cast the top cover 102 and the top beam 1021 in advance.

[0044] The second step is to cast supporting brackets 104 on both sides of the inner wall of the front anchor chamber 101 near the top after the main body 1 is built.

[0045] The third step is to hoist and transport the prefabricated top cover 102 and top beam 1021 after the supporting bracket 104 is cast in place, and place them directly onto the supporting bracket 104 through the top beam 1021, thereby completing the placement of the top cover 102 and the closure of the front anchor chamber 101.

[0046] The fourth step is to connect the top cover 102 with the side walls 103 by casting on both sides of the top cover 102, so that the top cover 102 will form an integral whole with the two sides of the front anchor chamber 101 through the connecting side walls 103.

[0047] In the third step, when the top beam 1021 is placed on the top cover 102, the top beam 1021 will abut against the straightening component when it is hoisted from below. The inclined surface of the straightening component and the axial deflection and closing under pressure will apply pressure to the suspended top cover 102, so that the top cover 102 will be straightened towards the center. This will ensure that the top cover 102 is placed accurately and avoids subsequent movement.

[0048] The following is a detailed implementation process of this invention: First, after the main body 1 is assembled, a front anchor chamber 101 is reserved. Then, the top cover 102 is prefabricated, and several top beams 1021 are connected to the bottom of the top cover 102. After the main body 1 is assembled, support brackets 104 are cast in place on both sides of the inner wall of the front anchor chamber 101 near the top. Then, the top cover 102 is hoisted onto the front anchor chamber 101 for installation. The top beams 1021 will abut against the support brackets 104 for load-bearing. After the top cover 102 is placed, side walls 103 are cast in place on both sides of it. 3. This allows the top cover 102 to be integrally set with the side wall of the front anchor chamber 101, thereby increasing the stability of the top cover 102. It also reduces the number of steps required to assemble the bottom support of the top cover 102, enabling direct, integral connection. When the top cover 102 is hoisted and placed, the bottom top beam 1021 first abuts against the abutment block 1053 in the fitting groove 1052 on one side of the straightening block 105. Due to the inclined setting of the abutment block 1053, the top beam 1021 slides along the center of the abutment block 1053, thus allowing for initial straightening of the top beam 1021. Meanwhile, the top beam 1021... Because the suspended installation makes it prone to swaying and correction, the entire straightening block 105 is connected to the pre-reserved installation groove 1041 during the casting of the supporting bracket 104 via a hinge shaft 1054. Simultaneously, the pressure block 1051 at the bottom of the straightening block 105 is connected to the groove in the installation groove 1041 via a spring, causing the entire straightening block 105 to deflect outwards, widening its center width. This allows the top beam 1021 to contact and correct between the two side abutment blocks 1053 even with some deviation. After the top beam 1021 is initially corrected by the abutment blocks 1053, it continues to... When the device is placed upright, pressure is applied to the abutment block 1053, causing the entire correction block 105 to reset and deflect. When the correction block 105 resets and closes, it further applies active pressure to the top beam 1021 to correct it, allowing it to move towards the center. When the top beam 1021 is below, the weight will continuously force the correction block 105 to reset and close until the pressure block 1051 is completely fitted into the mounting groove 1041, so that the correction block 105 is placed vertically and fits against both sides of the top beam 1021, making it completely fit into the gap between the sides of the top beam 1021 and the top cover 102.

[0049] The above are merely preferred embodiments of the present invention and are not intended to limit the present invention. Various modifications and variations can be made to the present invention by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the scope of protection of the present invention.
