Description

Technical Field

[0001] This utility model relates to the field of bridge deck manufacturing, and in particular to an intermittent bridge deck forming mold. Background Technology

[0002] In existing bridge deck manufacturing technologies, there is no specific manufacturing equipment for intermittent bridge decks. Traditional manufacturing processes typically employ a single-piece sequential production model, where the production of the next bridge deck only begins after a series of processes, such as steel reinforcement binding, formwork installation, concrete pouring, curing, and demolding, have been completed for each individual bridge deck. This production method cannot achieve continuous operation, resulting in extremely low production efficiency, significantly extending the construction cycle, and making it difficult to meet the urgent needs of large-scale bridge construction projects.

[0003] Meanwhile, traditional manufacturing equipment lacks a precise positioning structure in the steel mesh positioning stage, making it difficult to accurately control the placement of steel bars. This can easily lead to deviations in the forming size of the steel mesh, affecting the structural strength of the bridge deck. In traditional processes, steel bars need to be tied manually in the casting mold during construction, and it is difficult to demold the formwork between multiple concrete sections. This manufacturing equipment improves the traditional bridge deck manufacturing method, making the entire manufacturing process smoother and improving construction efficiency. Utility Model Content

[0060] The manufacturing method of the above-described intermittent bridge deck manufacturing apparatus includes:

[0061] S1. Place the longitudinal reinforcement in the end positioning groove 304 in the shaping component 3, move the first steel bar support 306 to the marked position, and then tie the transverse reinforcement above the steel bar.

[0062] S2. While placing the longitudinal reinforcement, place the mold base 501 of the forming mold 5 on the vibrating table 4, start the positioning cylinder 405 to make the positioning plate 403 restrict the position of the mold base 501, and then connect the sling of the first winch 203 on the hoisting assembly 2 to the tied steel mesh 8.

[0063] S3. Lift the steel mesh 8 to a certain height, and then use the mobile motor 202 to move the steel mesh 8 to the top of the mold base 501, and place the horizontal bars in the corresponding second positioning slots 515 on the second steel support 504.

[0064] S4. Adjust the pull-up bolt 506 to bring the second steel bar support 504 to the calibration state, and then push the handle 514 to make the matching groove 511 on the closing plate 510 and the horizontal bar coaxial, thus completing the closure of the second positioning groove 515.

[0065] S5. Then use the pouring equipment to pour concrete at the designated position in the molding mold 5. After pouring is completed, start the vibrating motor 408. The vibrating motor 408 drives the convex plate 409 to make the vibrating plate 402 vibrate. After vibration is completed, wait for the concrete to set.

[0066] S6. After the concrete has initially set, the turning plate 508 is installed on both sides of the mold base 501, and then concrete is poured into the pouring groove 509 formed between the turning plate 508 and the mold base 501. During the initial setting of the concrete, the steel mesh 8 is tied in the shaping component 3.

[0067] S7, After pouring concrete, start the transverse motor 602 to move to both sides of the mold base 501, then connect the sling on the second winch 604 to the hoisting seat 507, hoist the mold base 501 to a certain height, start the transverse motor 602, hoist the forming mold 5 to the stationary platform 7, and wait for the secondary concrete to set.

[0068] S8. During the static setting process, the next mold base 501 can be placed on the vibrating table 4. After the previous static setting is completed, it is moved to the prefabrication yard for curing. When demolding, pull the handle 514 to make the closing plate 510 separate from the horizontal reinforcement, and rotate the pull bolt 506 to make the second steel reinforcement support 504 separate from the concrete, which facilitates subsequent demolding. After demolding, the mold base 501 is transported back to the manufacturing device for use.

[0069] S9. Repeat steps S1-S8 to complete the fabrication of the bridge deck.

[0070] Example 3

[0071] Further explanation in conjunction with Example 2, such as Figures 1-13 The structure shown illustrates in more detail the manufacturing process of an intermittent bridge deck manufacturing apparatus:

[0072] S1: Preparation for steel mesh binding:

[0073] The longitudinal reinforcement that meets the design requirements is placed in the end positioning groove 304 in the shaping component 3. The diameter and material of the longitudinal reinforcement are selected according to the design standards of the bridge deck, such as the common HRB400E steel bar. The size and spacing of the end positioning groove 304 are precisely designed to ensure that the longitudinal reinforcement is in the correct position.

[0074] Then, the first rebar support 306 is moved along the first guide rod 305 to the marked position. The marked position is determined by measuring tools according to the design dimensions of the rebar mesh 8. Then, horizontal bars are tied above the rebar strips. The horizontal bars are also HRB400E steel bars that meet the standards. During the tying process, iron wire is used to firmly tie the horizontal bars and the longitudinal bars. The specification of the iron wire is generally No. 22 galvanized iron wire to ensure the integrity of the rebar mesh 8 during subsequent handling and construction.

[0075] S2: Placement and positioning of molding die:

[0076] While placing the longitudinal ribs, place the mold base 501 of the forming mold 5 on the vibrating table 4. Before placing the mold base 501, check whether its surface is flat, whether it is deformed or damaged, and ensure that it can be used normally. After placing it, start the positioning cylinder 405. The working pressure of the positioning cylinder 405 is generally set to 0.4-0.6MPa. Through the extension of its output shaft, the positioning plate 403 is pushed up to limit the position of the mold base 501 and prevent the mold from shifting during subsequent operations.

[0077] At the same time, the sling of the first winch 203 on the hoisting assembly 2 is connected to the tied steel mesh 8. When connecting, ensure that the connection between the sling and the steel mesh 8 is firm and reliable, and use a special hook or clamp for connection.

[0078] S3: Lifting and placement of steel mesh:

[0079] The first winch 203 is started to lift the steel mesh 8 to a certain height. The lifting height is adjusted according to the actual operating space to ensure that the steel mesh 8 will not collide with surrounding equipment during movement. Then, the mobile motor 202 drives the lifting assembly 2 to move on the lifting guide rail 105, moving the steel mesh 8 above the mold base 501. During the movement, through observation and operation control, the transverse bars of the steel mesh 8 are aligned one-to-one with the second positioning grooves 515 on the second steel bar support 504 in the forming mold 5, ensuring the accurate position of the steel mesh 8 in the mold.

[0080] S4: Adjustment and sealing of molding die:

[0081] Adjust the pull-up bolt 506. By rotating the pull-up bolt 506, the second steel bar support 504 moves along the second guide rod 505 to reach the calibration state. This calibration state ensures that the position of the steel mesh 8 in the mold meets the standard according to the design requirements of the bridge deck.

[0082] Then, push the handle 514 to move the closing plate 510 laterally between the tail seat 512 and the front seat 513, so that the matching groove 511 on the closing plate 510 and the horizontal rib are coaxial, thus completing the closure of the second positioning groove 515 and preventing concrete leakage during concrete pouring.

[0083] S5: Concrete pouring and vibration:

[0084] Using professional concrete pouring equipment, such as a concrete pump, concrete material conforming to the design mix ratio is transported to the designated position in the molding mold 5 for pouring. The concrete mix ratio is designed according to the design strength grade of the bridge deck. During the pouring process, the pouring speed and height must be controlled to avoid concrete segregation.

[0085] After pouring is completed, start the vibrating motor 408. The working frequency and excitation force of the vibrating motor 408 are adjusted according to the slump of the concrete and the pouring thickness. The vibration time is generally 2-5 minutes. The vibrating motor 408 drives the convex plate 409 to make the vibrating plate 402 vibrate. The vibration causes the air bubbles inside the concrete to be expelled, making the concrete dense and bonded. After vibration is completed, wait for the concrete to set. The initial setting time depends on the concrete mix ratio and the ambient temperature, and is generally between 2-4 hours.

[0086] S6: Preparation and Operation for Secondary Pouring:

[0087] After the concrete has initially set, the turning plates 508 are installed on both sides of the mold base 501. During installation, ensure that the turning plates 508 are tightly connected to the mold base 501. This can be achieved by tightening with bolts. After installation, concrete is poured into the pouring groove 509 formed between the turning plates 508 and the mold base 501. The concrete mix ratio and pouring requirements for this pour are the same as the first one. During the initial setting of the concrete, the steel mesh 8 is tied to the shaping component 3 to prepare for the next production and improve production efficiency.

[0088] S7: Lifting and stationary placement of molding dies:

[0089] After the second concrete pour, start the transverse motor 602 to move the transverse component 6 to both sides of the mold base 501. During the movement, pay attention to the positional relationship between the transverse component 6 and the forming mold 5 to ensure accurate alignment. Then, connect the sling on the second winch 604 to the lifting seat 507. After the connection is secure, start the second winch 604 to lift the mold base 501 to a certain height. Then start the transverse motor 602 to lift the forming mold 5 onto the stationary platform 7 and wait for the second concrete pour to initially set. During the lifting process, keep it stable to avoid shaking or collision of the forming mold 5.

[0090] S8: Subsequent Processing and Circular Production

[0091] During the settling process, the next mold base 501 can be placed on the vibrating table 4 to start a new round of production. After the previous settling is completed, when the concrete reaches a certain strength, the forming mold 5 is moved to the prefabrication yard for curing. The curing method can be natural curing or steam curing, depending on the actual situation.

[0092] During demolding, pull handle 514 to detach the closing plate 510 from the horizontal reinforcement, and then rotate pull bolt 506 to detach the second steel reinforcement support 504 from the concrete to facilitate subsequent demolding. After demolding, inspect and clean the mold, and transport the mold base 501 back to the manufacturing device for later use.

[0093] Repeat steps S1-S8 to continuously complete the bridge deck fabrication. Throughout the entire production process, strictly follow the operating procedures to ensure product quality and production safety.
