Description

Technical Field

[0001] This invention relates to the field of beam bridge construction technology, specifically to a concrete pouring template for the construction of a top-launching type steel plate composite beam bridge. Background Technology

[0002] With the rapid development of mountain roads, due to the rugged terrain and particularly harsh transportation and construction conditions, the incremental launching steel plate composite beam bridge is a better construction choice considering factors such as transportation. The construction of the incremental launching steel plate composite beam bridge requires the pouring of concrete slabs, and concrete pouring formwork is an indispensable tool.

[0003] Existing concrete pouring formwork mostly relies on vibrating motors to directly vibrate and defoam the concrete during use. However, vibration at a certain frequency and intensity is insufficient to efficiently improve the uniformity and defoaming effect of the concrete. The concrete in the formwork is not uniformly distributed after pouring, and it is difficult to quickly and evenly distribute the concrete using only a vibrating motor. Vibrating motors are more suitable for defoaming than for even distribution, which has drawbacks. This invention designs a top-push type concrete pouring formwork for the construction of steel plate composite beam bridges to solve the above problems. Summary of the Invention

[0004] The purpose of this invention is to provide a concrete pouring formwork for the construction of a top-push type steel plate composite beam bridge, in order to solve the problem mentioned in the background art that most of the concrete is directly vibrated and defoamed by a vibrating motor. However, the vibration of a certain frequency and intensity is difficult to efficiently improve the uniformity and defoaming degree of the concrete. The position of the concrete in the freshly poured formwork is not uniform enough, and it is difficult to quickly and evenly distribute the concrete by a vibrating motor alone.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a concrete pouring formwork for the construction of a top-push type steel plate composite beam bridge, comprising a formwork 1, a formwork 2 disposed at the upper end of the formwork 1, the formwork 2 located on the upper end face of the formwork 1, a limiting hole being provided between the formwork 1 and the formwork 2, a connecting mechanism being provided at the position between the exterior of the formwork 1 and the formwork 2, and a defoaming mechanism being provided at the lower end face of the formwork 1.

[0006] The defoaming mechanism includes a fixed plate, ball bearings, a bottom frame, a connecting pad, a vibration motor, and a drive mechanism. There are two fixed plates, which are fixedly connected to both sides of the lower end face of the template. The ball bearings are slidably embedded in the lower end of the fixed plate. The bottom frame is set outside the fixed plate, and the fixed plate and the bottom frame are connected by a connecting pad. The vibration motor is fixedly connected to both sides of the lower end face of the template.

[0007] Preferably, the drive mechanism includes a connecting plate, a drive motor, a cam, and a through hole, with the connecting plate fixedly connected between two fixed plates.

[0008] Preferably, the drive motor is located in the middle of the bottom frame, the output end of the drive motor is fixedly connected to the cam, the through hole is opened inside the connecting plate, the cam is located inside the through hole, and the through hole is an elliptical hole.

[0009] Preferably, the connecting mechanism includes a connecting frame, a plate, a hinge, a mounting plate, and a fastening mechanism. The plate is fixedly connected to one side of the template one, and the mounting plate is fixedly connected to one side of the template two.

[0010] Preferably, the connecting frame is connected to the plate body via a hinge, and the connecting frame is U-shaped.

[0011] Preferably, the fastening mechanism includes a pull ring, a spring, a limiting pin, and a baffle, with the limiting pin sliding through the interior of the connecting frame.

[0012] Preferably, the baffle is fixedly connected to the outer surface of the limiting pin, and the spring is sleeved on the outside of the limiting pin, with the spring in contact with the baffle.

[0013] Preferably, the pull ring is fixedly connected to the upper end face of the limiting pin, and the lower end of the limiting pin is inserted into the interior of the mounting plate.

[0014] Compared with the prior art, the beneficial effects of the present invention are: the connecting frame is moved by the hinge, and the limiting pin is pulled upward by the pull ring. When the connecting frame contacts the mounting plate, the pulling force on the pull ring is released, and the baffle can be pushed under the action of the spring. This allows the limiting pin to be inserted into the inside of the mounting plate, connecting the connecting frame and the mounting plate, thus realizing the connection between template one and template two. The operation is quick and stable, and it is also convenient for subsequent demolding.

[0015] The drive motor starts, causing the cam to rotate. The cam then contacts the perforation, pushing the connecting plate back and forth. This, in turn, moves the fixing plate, which moves inside the base frame via ball bearings. During this movement, the connecting pad deforms, sealing the gap between the fixing plate and the base frame to prevent debris from falling in. This also helps to evenly distribute the concrete between formwork one and formwork two, expelling air bubbles. Then, the vibration motor is started to vibrate formwork one and formwork two at a high frequency, expelling small air bubbles from the concrete. First, large vibrations evenly distribute the concrete and expel some air bubbles, followed by high-frequency small vibrations to expel smaller air bubbles. This staged process greatly improves the efficiency of concrete pouring while ensuring its quality, making it quite practical.

[0016] Of course, any product implementing this invention does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0025] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0026] Please see Figures 1 to 5 The present invention provides a concrete pouring formwork technical solution for the construction of a top-push type steel plate composite beam bridge: including formwork 1, formwork 2 is set at the upper end of formwork 1, formwork 2 is located at the upper end face of formwork 1, a limiting hole 3 is opened between formwork 1 and formwork 2, a connecting mechanism 11 is set at the position between the exterior of formwork 1 and formwork 2, and a defoaming mechanism is set at the lower end face of formwork 1.

[0027] The defoaming mechanism includes a fixed plate 4, ball bearings 5, a bottom frame 7, a connecting pad 8, a vibration motor 6, and a drive mechanism. There are two fixed plates 4, which are fixedly connected to both sides of the lower end face of the template 1. The ball bearings 5 ​​are slidably embedded in the lower end of the fixed plate 4. The bottom frame 7 is set outside the fixed plate 4. The fixed plate 4 and the bottom frame 7 are connected by the connecting pad 8. The vibration motor 6 is fixedly connected to both sides of the lower end face of the template 1.

[0028] Concrete slurry is poured into the interiors of formwork 1 and formwork 2. Then, drive motor 10 starts, rotating cam 21. Cam 21 then contacts the perforation 20, pushing connecting plate 9 back and forth. This moves fixing plate 4, which moves inside the base frame 7 via ball bearings 5. During this movement, connecting pad 8 deforms, sealing the gap between fixing plate 4 and base frame 7 to prevent debris from falling in. This also evenly distributes the concrete between formwork 1 and formwork 2, expelling air bubbles. Then, the vibration motor 6 is started to vibrate the template 1 and template 2. The vibration frequency is high, which can expel small air bubbles in the concrete. The driving mechanism includes a connecting plate 9, a driving motor 10, a cam 21 and a through hole 20. The connecting plate 9 is fixedly connected between two fixed plates 4. The driving motor 10 is set in the middle of the bottom frame 7. The output end of the driving motor 10 is fixedly connected to the cam 21. The through hole 20 is opened inside the connecting plate 9. The cam 21 is located inside the through hole 20. The through hole 20 is an elliptical hole.

[0029] The connecting mechanism 11 includes a connecting frame 13, a plate 15, a hinge 14, a mounting plate 16, and a fastening mechanism. The plate 15 is fixedly connected to one side of the template 1, and the mounting plate 16 is fixedly connected to one side of the template 2. The connecting frame 13 is connected to the plate 15 through the hinge 14. The connecting frame 13 is U-shaped. The fastening mechanism includes a pull ring 19, a spring 18, a limiting pin 12, and a baffle 17. The limiting pin 12 slides through the inside of the connecting frame 13. The baffle 17 is fixedly connected to the outer surface of the limiting pin 12. The spring 18 is sleeved on the outside of the limiting pin 12 and contacts the baffle 17. The pull ring 19 is fixedly connected to the upper end face of the limiting pin 12, and the lower end of the limiting pin 12 is inserted into the inside of the mounting plate 16.

[0030] A specific application of this embodiment is as follows: When pouring concrete for a bridge, the reinforcing bars need to be arranged in the formwork beforehand, with both ends of the reinforcing bars placed in the limiting holes 3. At this time, formwork 1 and formwork 2 are separated. After arranging the reinforcing bars, formwork 2 is connected to formwork 1. First, the connecting frame 13 is moved by the hinge 14, and at the same time, the limiting pin 12 is pulled upward by the pull ring 19. When the connecting frame 13 contacts the mounting plate 16, the pulling force on the pull ring 19 is released, and the baffle 17 can be pushed under the action of the spring 18. This allows the limiting pin 12 to be inserted into the interior of the mounting plate 16, connecting the connecting frame 13 and the mounting plate 16. This achieves the connection between formwork 1 and formwork 2, which is quick and stable, and facilitates subsequent demolding. Then, the concrete slurry is poured into the interior of formwork 1 and formwork 2. Then, the drive motor 10 starts and drives the cam 21 to rotate. The cam 21 then contacts the perforation 20, which pushes the connecting plate 9 back and forth. This then drives the fixing plate 4 to move. The fixing plate 4 moves inside the bottom frame 7 via the ball bearings 5. During the movement, the connecting pad 8 deforms, which seals the gap between the fixing plate 4 and the bottom frame 7, preventing debris from falling in. This shakes the concrete between template 1 and template 2 evenly, allowing air bubbles to escape. Then, the vibration motor 6 is started to vibrate template 1 and template 2. The vibration frequency is high, which allows small air bubbles in the concrete to escape. First, the large wave motion evenly distributes the concrete and removes some air bubbles. Then, the high-frequency small wave motion removes small air bubbles. This staged treatment can greatly improve the efficiency of concrete pouring and ensure the quality of the pouring, making it quite practical.
