Description

Technical Field

[0001] This invention relates to the field of continuous beam construction technology, and specifically to a hanging basket for continuous beam construction. Background Technology

[0002] The formwork is a core piece of equipment in cantilever construction, and its performance directly affects the safety and quality of bridge construction. After the formwork is assembled, a pre-stressing test must be conducted to eliminate inelastic deformation, measure elastic deformation data, and verify the formwork's load-bearing capacity and safety, providing a basis for the formwork elevation of subsequent cantilever segments.

[0003] Currently, the main pre-compression solutions for hanging baskets are: (a) Traditional surcharge preloading method: including sandbag method, steel bar surcharge method, water tank method, etc., that is, sandbags, steel bars or water tanks are directly hoisted on the bottom formwork of the hanging basket, and preloading test is carried out by loading and unloading in stages as required. This method has the following defects: (1) complex process, long test cycle and high cost; (2) high-altitude surcharge operation, the height of the surcharge is high, and there is a very high safety risk.

[0004] (II) Reaction Frame Hydraulic Preloading Method: This method utilizes a reaction frame in conjunction with jacks for preloading. For example, patent CN202787086U discloses a preloading device for cantilever casting construction using a suspended formwork. It employs a counter-pressure precision-rolled threaded steel rod, with a hydraulic jack installed at the upper end and the lower end pre-embedded in the foundation. Preloading of the suspended formwork is achieved through tensioning. While this method saves working space, it still requires pre-embedding precision-rolled threaded steel in the foundation, causing damage to the existing structure. Furthermore, the reaction frame installation is complex, and the amount of high-altitude work remains significant.

[0005] (iii) Ground tensioning preloading method: As disclosed in patent CN211285289U, this method uses upper and lower anchoring components, and replaces the load with the reaction force of tensioned steel strands. This type of solution moves the power source to the ground, which reduces the load at high altitudes to some extent, but the connection between the jacks and the hanging basket still requires high-altitude operations.

[0006] In summary, existing technologies for continuous beam construction using hanging baskets all require extensive high-altitude operations during preloading, including the surcharge method, the reaction frame hydraulic preloading method, and the ground tensioning preloading method. The surcharge method requires hoisting sandbags at height; the reaction frame hydraulic preloading method requires installing reaction frames and jacks at height; and the ground tensioning preloading method requires threading steel strands at height. These high-altitude operations are not only inefficient but also pose serious safety hazards. In the ground tensioning preloading method, existing technologies generally employ a "ground power + flexible force transmission" model. For example, pulley blocks are installed at the bottom of the membrane, and steel strands are connected to the hanging basket by passing them around the pulley blocks. The bending of the steel strands and the friction of the pulley blocks cause significant errors in load transfer, making it difficult to accurately simulate actual construction loads. Summary of the Invention

[0007] In order to solve the above-mentioned technical problems, or at least partially solve the problems of large amount of high-altitude work, high safety risks and low load accuracy in the ground tensioning and preloading method, this disclosure provides a hanging basket for continuous beam construction.

[0008] To achieve the aforementioned objectives, the present invention provides a hanging basket for continuous beam construction, comprising a hanging basket on which a template is installed, a bottom basket connected to the bottom of the template, a counterweight block placed on the bottom basket, a connector provided at the bottom of the template, a preloading box connected to the top of the bottom basket via steel strands, a hook provided at the top of the preloading box, and a pair of lifting lugs provided on both sides of the preloading box, the preloading box being able to be suspended by the hooks at the bottom of the connector by a hoisting method.

[0009] Optionally, the connector includes a main frame, a channel, and a suspension rod. The top of the main frame is fixedly connected to the bottom of the template. The channel is located in the middle of the main frame. Two hooks are provided. The hooks can enter the interior of the main frame from the channel. The suspension rods are located at the bottom of both sides of the channel. The hooks can be suspended on the suspension rods by moving downwards inside the channel.

[0010] Optionally, limit rods are provided on both sides of the bottom of the connector, and limit holes are provided on both sides of the top of the pre-compression box. When the hook is fitted onto the suspension rod from top to bottom, the limit rod is fitted onto the limit hole from top to bottom.

[0011] Optionally, the hook includes a vertical portion, an inclined portion, and a U-shaped portion. The bottom end of the vertical portion is fixedly connected to the top of the pre-pressing box, the bottom end of the inclined portion is connected to the top of the vertical portion, the U-shaped portion is in an inverted state, and one end of the U-shaped portion is connected to the top of the inclined portion. The inner cavity width of the U-shaped portion is set to match the outer diameter of the suspension rod. The two inclined portions are oriented in opposite directions. When the hook enters the channel, the suspension rod is located within the range of the vertical portion in the height direction.

[0012] Optionally, the pre-compression box is equipped with a through-hole jack, and multiple steel strands are equidistantly arranged around the through-hole jack in a circumferential direction. The top ends of the steel strands are connected to the through-hole jack, and when the through-hole jack extends, it can lift the bottom basket to a suspended state through the steel strands.

[0013] Optionally, the through-hole jack includes a fixed part and a movable part. A central sleeve is provided at the center of the through-hole jack. The top of the central sleeve is fixedly connected to the movable part. An elastic element is fixedly connected to the inner top wall of the central sleeve. A connecting plate is fixedly connected to the bottom end of the elastic element. The connecting plate slides with the central sleeve in the height direction. The top of the steel strand is fixedly connected to the connecting plate.

[0014] Optionally, the inner diameter of the bottom end of the central sleeve is smaller than the outer diameter of the connecting plate, and the cavity length of the central sleeve is smaller than the maximum extension distance of the elastic element. When the hook is flush with the channel, the bottom of the connecting plate is supported by the bottom of the central sleeve.

[0015] Optionally, a guide wheel is provided at the center of the top of the active part, and a guide rail is fixedly provided at the top of the channel. One end of the guide rail extends from the channel and extends to the outside of the template. The guide wheel guides the pre-compression box to move by moving the top of the guide rail into the channel, so that the hook enters the channel.

[0016] Optionally, a lifting space is provided between the top of the guide rail and the top wall of the channel, and when the through-hole jack lifts the bottom basket, the guide wheel moves upward within the lifting space.

[0017] Optionally, the guide wheel includes a guide rod and a wheel body. The guide rod includes a vertical section and a horizontal section fixedly connected to the top of the vertical section. The bottom end of the vertical section is fixedly connected to the top center of the movable part. The end of the horizontal section away from the vertical section extends from between the two hooks to the outside of the hooks. The wheel body is rotatably mounted at both ends of the horizontal section. The middle of the guide rail is provided with a through groove for the movement of the vertical section.

[0018] The technical solution provided in this disclosure has the following advantages compared with the prior art: 1. The combination of the connector, preloading box, hook, and steel strand in this application allows the preloading box to be directly suspended to the bottom of the connector by hoisting, eliminating the need for high-altitude operations when connecting the bottom basket and the template, thus improving both work efficiency and safety. On the other hand, after the template and the bottom basket are connected, a combined connection method of upper rigid connection and lower flexible connection is formed. The upper rigid connection has a better force transmission effect and horizontal constraint effect, resulting in higher load accuracy and improving the accuracy of the preloading test. The lower flexible connection can improve the adaptability and adjustment capability of the bottom basket position.

[0019] 2. The through-hole jack of this application raises the bottom basket to a suspended state, so that the weight of the bottom basket and the counterweight blocks forms a preload on the hanging basket. During the placement and removal of the counterweight blocks, the bottom basket can remain on the ground, which makes the bottom basket more stable and facilitates the placement and removal of the counterweight blocks, thereby improving the construction efficiency and safety of the preload operation.

[0020] 3. The cooperation of the center sleeve, elastic element, connecting plate and through-hole jack in this application allows the elastic element and steel strand to apply a downward pulling force to the pre-pressure box during the hoisting process, so that the pre-pressure box can maintain its posture more stably and facilitate the docking operation between the pre-pressure box and the connector.

[0021] 4. The coordination of the guide wheel, guide rail, and elastic element in this application allows the steel strand to be inclined when the guide wheel falls onto the guide rail during the hoisting of the pre-compression box, and the elastic element to be stretched. The horizontal component of the elastic force of the elastic element is applied to the pre-compression box, forming an auxiliary force that moves the pre-compression box toward the connector. At the same time, by controlling the extension and retraction of the through-hole jack, the horizontal tension of the elastic element on the pre-compression box can be adjusted, thus making it easier to connect the pre-compression box with the connector.

Therefore, they have no substantial technical significance. Any modifications to the structure, changes in the proportional relationships, or adjustments to the size, without affecting the effects and objectives that the present invention can produce, should fall within the scope of the technical content disclosed in the present invention. It should be noted that in this specification, relational terms such as "first" and "second" are only used to distinguish one entity from several other entities, and do not necessarily require or imply any actual relationship or order between these entities.

[0026] like Figures 1 to 3 As shown, this embodiment discloses a hanging basket for continuous beam construction, including a hanging basket 1, a template 2 installed on the hanging basket 1, a bottom basket 3 connected to the bottom of the template 2, a counterweight block placed on the bottom basket 3, a connector 4 provided at the bottom of the template 2, and a preloading box 6 connected to the top of the bottom basket 3 by a steel strand 5. A hook 7 is provided at the top of the preloading box 6, and a pair of lifting lugs are provided on both sides of the preloading box 6. The preloading box 6 can be suspended by the hook 7 at the bottom of the connector 4 by hoisting.

[0027] The connector 4 can be fixed to the bottom of the template 2 by bolting or welding. During the fabrication of the template 2, the connector 4 can be directly fixed to the bottom of the template 2, thus eliminating the need for fixing the connector 4 to the bottom of the template 2 during the on-site assembly of the hanging basket 1. In this embodiment, four connectors 4 are provided at the bottom of the template 2.

[0028] When lifting the pre-compression box 6 by crane, a four-hook method is adopted, with two pairs of hooks working in conjunction with two pairs of lifting lugs to better maintain the balance of the pre-compression box 6 and facilitate the connection between the hook 7 and the connector 4, thereby making it easier to connect the pre-compression box 6 and the connector 4.

[0029] When the hanging basket is used for pre-compression, the pre-compression box 6 is connected to the connector 4 by hoisting, so that the bottom basket 3 and the template 2 can be connected. The whole process does not require high-altitude operation, which has higher safety and convenience.

[0030] After the pre-compression box 6 is connected to the connector 4, the pre-compression box 6 and the connector 4 are in a rigid suspension state, with strong force transmission performance and stability. The bottom basket 3 is suspended at the bottom of the pre-compression box 6 by the steel strand 5, so that the position of the bottom basket 3 can be adjusted adaptively.

[0031] like Figure 4 As shown, the connector 4 includes a main frame 401, a channel 402, and a suspension rod 403. The top of the main frame 401 is fixedly connected to the bottom of the template 2. The channel 402 is located in the middle of the main frame 401. There are two hooks 7. The hooks 7 can enter the interior of the main frame 401 through the channel 402. The suspension rods 403 are located at the bottom of both sides of the channel 402. The hooks 7 can be suspended on the suspension rods 403 by moving downward inside the channel 402.

[0032] By fixing the top of the main frame 401 to the bottom of the template 2, the connector 4 can be fixedly installed to the bottom of the template 2. When hoisting the pre-compression box 6, the height of the hook 7 is matched with the channel 402 by controlling the crane. Then, the height of the pre-compression box 6 is maintained, and the pre-compression box 6 is moved horizontally. After the hook 7 enters the channel 402, the pre-compression box 6 is lowered. The hook 7 can be put on the suspension rod 403 from top to bottom, thus completing the docking of the pre-compression box 6 and the connector 4.

[0033] After the pre-compression box 6 and the connector 4 are connected, the pre-compression box 6, under its own weight, allows the hooks 7 to be stably suspended on the suspension rods 403, making them less prone to detachment. At the same time, the two hooks 7, together with the two suspension rods 403, can effectively limit the movement in the horizontal direction, reducing the swaying of the pre-compression box 6 and improving its stability.

[0034] like Figure 2 and Figure 5 As shown, limit rods 8 are provided on both sides of the bottom of the connector 4, and limit holes 9 are provided on both sides of the top of the pre-compression box 6. When the hook 7 is fitted onto the suspension rod 403 from top to bottom, the limit rods 8 are fitted onto the limit holes 9 from top to bottom. When the pre-compression box 6 and the connector 4 are connected, the limit rods 8 can improve the stability between the pre-compression box 6 and the connector 4 by inserting into the limit holes 9, thereby improving safety.

[0035] like Figure 2 As shown, the hook 7 includes a vertical portion 701, an inclined portion 702, and a U-shaped portion 703. The bottom end of the vertical portion 701 is fixedly connected to the top of the pre-pressing box 6. The bottom end of the inclined portion 702 is connected to the top end of the vertical portion 701. The U-shaped portion 703 is in an inverted state, and one end of the U-shaped portion 703 is connected to the top end of the inclined portion 702. The inner cavity width of the U-shaped portion 703 is set to match the outer diameter of the suspension rod 403. The two inclined portions 702 are oriented in opposite directions. When the hook 7 enters the channel 402, the suspension rod 403 is located within the vertical portion 701 in the height direction.

[0036] To facilitate the entry of hook 7 into channel 402, the size of channel 402 is larger than the size of the area enclosed by the two hooks 7. After hook 7 enters channel 402, when hook 7 is misaligned with suspension rod 403 laterally, during the lowering of pre-compression box 6, the inclined portion 702 contacts suspension rod 403. Suspension rod 403 can correct the position of pre-compression box 6, so that suspension rod 403 can be aligned with the bottom opening of U-shaped portion 703 before entering U-shaped portion 703. This improves the docking accuracy between pre-compression box 6 and connector 4, eliminating the need for repeated adjustments of pre-compression box 6 using a crane, thus facilitating docking of pre-compression box 6 with connector 4.

[0037] like Figure 5 As shown, a through-hole jack 10 is provided inside the pre-compression box 6. Multiple steel strands 5 are equidistantly arranged around the through-hole jack 10 in a circumferential direction, and the top of the steel strands 5 is connected to the through-hole jack 10. When the through-hole jack 10 extends, it can lift the bottom basket 3 to a suspended state through the steel strands 5.

[0038] Using the through-hole jack 10 to suspend the steel strands 5 makes it easier to set up the steel strands 5. At the same time, multiple steel strands 5 improve the safety of the pre-loading operation. In the initial state, the bottom basket 3 can be placed directly on the ground, making it easier to place and remove the counterweights. During the pre-loading test, the bottom basket 3 is lifted to a suspended state using the through-hole jack 10, thus achieving pre-loading of the hanging basket 1.

[0039] like Figure 6 and Figure 7 As shown, the through-hole jack 10 includes a fixed part and a movable part. A central sleeve 11 is provided in the center of the through-hole jack 10. The top of the central sleeve 11 is fixedly connected to the movable part. An elastic element 12 is fixedly connected to the inner top wall of the central sleeve 11. A connecting plate 13 is fixedly connected to the bottom end of the elastic element 12. The connecting plate 13 slides with the central sleeve 11 in the height direction. The top of the steel strand 5 is fixedly connected to the connecting plate 13.

[0040] In this embodiment, the elastic element 12 is an elastic telescopic rod. In the initial state, the through-hole jack 10 is in the retracted state, and the elastic element 12 is in its shortest state. When the crane lifts the preload box 6 to a height where the hook 7 is flush with the channel 402, the elastic element 12 is pulled up. At this time, the steel strand 5 exerts a downward pulling force on the preload box 6, which can cooperate with the crane to help stabilize the posture of the preload box 6, making the posture of the preload box 6 and the hook 7 more stable during the process of the hook 7 entering the channel 402.

[0041] The two pairs of lifting lugs are distributed on the side wall of the pre-compression box 6 parallel to the orientation of the channel 402, with the bottom of the lifting lugs open. When lifting the pre-compression box 6, four hooks are used in conjunction with two pairs of lifting lugs for lifting. When the pre-compression box 6 is lifted to a height where the hook 7 is flush with the channel 402, the two hooks closest to the channel 402 are loosened, so that the two hooks closest to the channel 402 automatically detach and disengage from the pre-compression box 6.

[0042] At this time, the pre-compression box 6 is suspended separately by another pair of hooks. The length of the steel strand 5 allows the pre-compression box 6 to tilt at its bottom away from the channel 402 under its own weight. Then, by controlling the upward extension of the movable part, the tension on the steel strand 5 is increased. The reaction force exerted by the steel strand 5 on the pre-compression box 6 can straighten the pre-compression box 6, adjust the posture of the pre-compression box 6 so that the hook 7 is facing the channel 402, making it easier for the pre-compression box 6 to connect to the connector 4.

[0043] like Figure 7 As shown, the inner diameter of the bottom end of the center sleeve 11 is smaller than the outer diameter of the connecting plate 13, and the cavity length of the center sleeve 11 is smaller than the maximum extension distance of the elastic element 12. When the hook 7 is flush with the channel 402, the bottom of the connecting plate 13 is supported by the bottom of the center sleeve 11. This arrangement can prevent the elastic element 12 from being overstretched, thus protecting the elastic element 12.

[0044] like Figure 2 , Figure 3 and Figure 5 As shown, a guide wheel 14 is centrally located at the top of the movable part, and a guide rail 15 is fixedly installed at the top of the channel 402. One end of the guide rail 15 extends from the channel 402 to the outside of the template 2. The guide wheel 14 guides the preload box 6 to move into the channel 402 by moving the top of the guide rail 15, and can keep the height of the hook 7 always adapted to the channel 402, so that the hook 7 can enter the channel 402 more accurately. Specifically, the guide rail 15 is parallel to the width direction of the continuous beam, and the end of the guide rail 15 away from the middle of the continuous beam extends to the outside of the template 2 in an exposed state, thereby avoiding interference between the hanging basket 1 and the crane boom during the hoisting operation, so that the boom can move the preload box 6 outside the hanging basket 1 and move the guide wheel 14 onto the guide rail 15.

[0045] During the hoisting of the pre-compression box 6 and the connector 4, the pre-compression box 6 is first hoisted onto the guide wheel 14 and placed on the guide rail 15 using a crane. In this state, the guide rail 15, in conjunction with the guide wheel 14, provides suspension and stability for the pre-compression box 6. At this time, the horizontal component of the tension force exerted by the elastic element 12 on the pre-compression box 6 points towards the channel 402. By slowly releasing the tension force on the pre-compression box 6 through the operation of the crane, the pre-compression box 6 can automatically move into the channel 402 under the action of the horizontal component of the elastic element 12, achieving a more convenient and safer docking operation between the pre-compression box 6 and the connector 4.

[0046] As the preload box 6 moves toward the connector 4, the horizontal tension applied by the elastic element 12 to the preload box 6 will decrease. At this time, by controlling the movable part to extend upward, the top of the steel strand 5 can be pulled upward further, which can compensate for the horizontal tension of the steel strand 5 on the preload box 6, thereby better assisting the preload box 6 in docking with the connector 4.

[0047] like Figure 2 and Figure 4 As shown, a lifting space is provided between the top of the guide rail 15 and the inner top wall of the channel 402. When the through-hole jack 10 lifts the bottom basket 3, the guide wheel 14 moves upward within the lifting space. During pre-compression, the guide wheel 14 disengages from the guide rail 15, causing the guide rail 15 to deform due to excessive force.

[0048] like Figure 2 , Figure 3 and Figure 5 As shown, the guide wheel 14 includes a guide rod 1401 and a wheel body 1402. The guide rod 1401 includes a vertical section and a horizontal section fixedly connected to the top of the vertical section. The bottom end of the vertical section is fixedly connected to the top center of the movable part. The end of the horizontal section away from the vertical section extends from between the two hooks 7 to the outside of the hooks 7. The wheel body 1402 is rotatably mounted at both ends of the horizontal section. The guide rail 15 is provided with a through groove 16 for the movement of the vertical section in the middle.

[0049] During the operation of connecting the pre-compression box 6 to the connector 4, when the pre-compression box 6 is hoisted to the height of the hook 7 and the channel 402, the wheel 1402 is on the side of the hook 7 facing the channel 402, so that the guide wheel 14 will not interfere with the guide rail 15 and the hook 7 during the process of placing the guide wheel 14 on the guide rail 15, making the operation more convenient.

[0050] Although embodiments of the invention have been described in conjunction with the accompanying drawings, those skilled in the art can make various modifications and variations without departing from the spirit and scope of the invention, and such modifications and variations all fall within the scope defined by the appended claims.
