Description

Technical Field

[0001] The present invention belongs to the technical field of building construction, and more specifically, relates to a system and method for quickly aligning non-standard prefabricated components for bridges. Background Art

[0002] The precast component alignment device is a crucial component that directly determines whether the overall assembly between the precast component and the upper and lower bridge piers meets requirements. It primarily achieves precise positioning of the precast component and the upper and lower bridge piers through its guidance and adjustment.

[0003] At present, the positioning devices used when installing prefabricated components between upper and lower piers mostly rely on mechanical methods to adjust the horizontal and vertical directions, such as hydraulic jack systems and construction platforms. These devices mainly use the working principle of the mechanical system to perform subtle adjustments to achieve the purpose of precise positioning.

[0004] However, for objects with large volume and weight, the use of mechanical methods for precision adjustment requires the construction platform to support the entire object, which increases construction costs. At the same time, it has high requirements for the mechanical system itself, and it is necessary to operate the mechanical system in a limited space and make subtle observations to ensure that the entire adjustment meets the requirements. There are defects such as limited construction space and inconvenient operation, which seriously affect construction efficiency. Therefore, there is an urgent need for a prefabricated component precision and rapid alignment system that is not restricted by construction space, does not rely on a construction platform, can effectively reduce construction costs, can quickly and accurately perform positioning operations, and is easy to construct. Summary of the Invention

[0005] In response to the above defects or improvement needs of the prior art, the present invention provides a system and method for rapid alignment of non-standard prefabricated components for bridges, wherein a lifting wall for lifting the prefabricated components is provided inside the prefabricated components, a plurality of positioning recesses are provided on the outer bottom of the prefabricated components, and positioning tenons respectively matching the plurality of positioning recesses are provided on the second pier. A special crane is used to lift the lifting wall and then lift the prefabricated component and place it on the first pier. The crane operator finely adjusts the crane so that the positioning recesses on the prefabricated concrete cap beam shell are aligned and installed on the positioning tenon on the first pier, thus completing the entire alignment process; a plurality of spacers protruding from the lower surface of the prefabricated component are prefabricated at the bottom of the lifting wall. The spacer load-bearing block is used to ensure that the positioning tenon is not stressed when the prefabricated component falls on the first pier. After the positioning is completed, the positioning tenon can be removed and recycled. The present invention adopts the mortise and tenon principle, and the structure is simple, which is convenient for construction and production. At the same time, the positioning tenon is designed to be detachable, which is convenient for recycling and can effectively save costs. The construction is not restricted by space and does not rely on the construction platform, which can effectively reduce construction costs and can perform positioning operations quickly and accurately, and the construction is simple. It can solve the problems of the existing positioning device using mechanical methods to perform precision adjustment, which requires the construction platform to be set up, resulting in high construction costs, and at the same time there are construction space limitations and inconvenient operations that seriously affect construction efficiency. It is very creative.

[0014] Furthermore, the prefabricated component is prefabricated from concrete and has a hollow structure.

[0015] Furthermore, a first notch is provided at the bottom of the prefabricated component for the second pier to pass through.

[0024] S500: The prefabricated components are completely lowered so that the multiple spaced load-bearing blocks at the bottom of the lifting wall all fall on the first pier column. This completes the entire alignment and installation process of the prefabricated components.

[0025] S600: Then, the positioning tenons are removed from the first pier column in sequence for recycling.

The construction is not limited by space and does not rely on the construction platform, which can effectively save construction costs, is simple and efficient, and is highly creative.

[0041] Furthermore, if Figure 1-Figure 3As shown, the prefabricated component 1 is mainly prefabricated from concrete and is a non-standard component; the prefabricated component 1 in this embodiment is a prefabricated cap beam shell, which is a hollow boat-shaped structure; the bottom of the prefabricated component 1 is provided with a first notch 12 for the second pier 3 to pass through; the second pier 3 refers to the pier located above the first pier 2; the bottom of the prefabricated component 1 is provided with a second notch 13 with an opening facing downward that matches the shape and size of the upper surface of the first pier; during work, a crane is used to lift the prefabricated component and pass the first notch through the second pier so that the positioning notch on the prefabricated component is aligned with the positioning tenon on the first pier, and the prefabricated component is lowered so that the second notch of the prefabricated component is just located on the first pier. The construction is simple, does not rely on the construction platform, and can effectively save construction costs.

[0042] Furthermore, if Figure 1-Figure 3 As shown, the lifting wall 4 is a rectangular plate structure, which is arranged in the hollow structure of the prefabricated component 1 and is cast as a whole with the prefabricated component 1 through concrete, which provides great convenience for the crane to lift the prefabricated component; the lifting walls 4 are preferably two, and are arranged in parallel and spaced on both sides of the first notch 12 on the prefabricated component, so that when the crane lifts the prefabricated component, the force is balanced, the construction is smooth, it is not restricted by the construction space, and it is safe and efficient.

[0043] Furthermore, if Figure 1-Figure 3 As shown, the top side of the first pier 2 is provided with a positioning groove 21 with the same number and spacing as the positioning notches on the prefabricated component and corresponding to each other. The positioning grooves 21 are rectangular grooves, and each positioning groove 21 is provided with a positioning tenon 5 that can be inserted into the positioning notch 11 on the prefabricated component. The positioning tenon 5 is provided with a mounting hole 51 for mounting the positioning tenon on the first pier for positioning; the shape and size of one end of the positioning tenon 5 close to the bottom of the positioning groove 21 matches the positioning groove 21, and is rectangular, and is connected to the bottom of the positioning groove 21 through the mounting hole 51; the end of the positioning tenon 5 away from the bottom of the positioning groove 21 is connected to the positioning groove 21 on the prefabricated component The shapes and sizes of the recesses match, and the end portion of the positioning tenon 5 away from the bottom of the positioning groove protrudes a certain height from the upper surface of the first pier 2 and can be inserted into the positioning recess 11, so that the alignment of the prefabricated component and the first pier is more accurate; the number of the positioning tenons 5 and the positioning recesses 11 is the same, and both are multiple, preferably 4, which increases the accuracy and speed of positioning; during construction, the crane operator fine-tunes the crane so that the various positioning recesses on the prefabricated component are aligned with the corresponding positioning tenons installed on the first pier. The construction does not rely on the construction platform and is not restricted by the construction space. The structure is simple, the construction is convenient, and it is safe and efficient.

[0044] Furthermore, if Figure 1-Figure 3As shown, there are multiple spacer load-bearing blocks 6 at the bottom of the lifting wall 4, which are rectangular block structures protruding from the bottom of the lifting wall and fitting with the upper surface of the first pier column, and preferably 4, which can balance the force between the prefabricated component and the first pier column to prevent excessive stress from causing damage to the pier column and the positioning tenon, thereby increasing construction costs; the spacer load-bearing blocks 6 protrude from the lower surface of the prefabricated component 1 by a certain height, which is greater than the height of the positioning tenon 5 protruding from the upper surface of the first pier column 2. Such a design can ensure that the positioning tenon 5 is fully aligned with the positioning recess 11 and after the spacer load-bearing blocks 6 are completely lowered onto the first pier column, there is still a gap between the positioning tenon 5 and the positioning recess 11. On the one hand, leaving a gap can make the prefabricated component and the first pier column more convenient, more accurate and faster to achieve positioning effect. On the other hand, it can make the positioning tenon 5 not subject to force and avoid damage. Moreover, after the positioning between the prefabricated component and the pier column is completed, the positioning tenon can be conveniently disassembled for recycling. The structure is simple and construction costs can be saved.
