Description

Technical Field

[0001] The utility model relates to the field of precast T-beam formwork pouring, and particularly relates to a precast T-beam hydraulic formwork device. Background Art

[0002] A T-beam refers to a beam with a T-shaped cross-section. The two sides that protrude are called flanges, and the middle part is called the beam rib. Since the T-beam is formed by removing the tensile zone concrete that has no effect on the flexural strength in a rectangular beam. It has the same flexural strength as the original rectangle, which can not only save concrete but also reduce the self-weight of the beam body and improve the spanning ability. Therefore, T-beams are widely used in current road and bridge construction.

[0003] Like other precast beam types, precast T-beams also require formwork to complete the precast process. Currently, for precast T-beams, the formwork design form of loose assembly and disassembly is still the most commonly used. The traditional formwork of loose assembly and disassembly adopts the combination of formwork and truss, and uses upper and lower tie rods for tension reinforcement. During installation, the formwork is connected piece by piece with bolts in the beam length direction to achieve the required beam length for pouring. Since the formwork needs to be installed and removed piece by piece, the installation and removal time is relatively long, and the work efficiency is low. Each time the formwork is disassembled and assembled, a hoisting device needs to be used frequently, increasing the construction cost; due to repeated disassembly and assembly of the formwork, the formwork is extremely easy to be knocked and deformed during hoisting, which brings difficulties to the later formwork adjustment work. At the same time, the formwork surface is extremely easy to be damaged, affecting the appearance of the finished T-beam.

[0004] Therefore, a precast T-beam hydraulic formwork device is proposed to solve the above technical problems. Summary of the Utility Model

[0005] The technical problem solved by the utility model lies in the problems that the existing formwork disassembly and assembly require a large amount of time, the work efficiency is low, and at the same time, the disassembly and assembly of the formwork require frequent use of hoisting equipment, increasing the construction cost.

[0006] To solve the above technical problems, the technical solutions adopted by the utility model are as follows:

[0007] A prefabricated T-beam hydraulic formwork device includes a base, on which a base plate is laid. On the left and right sides of the base plate, there is a moving track arranged along the axis direction of the base. A moving vehicle body is arranged on the moving track. A transverse moving groove extending to the side wall of the moving vehicle body close to the base is arranged on the moving vehicle body, and a side formwork vertically arranged is arranged in the transverse moving groove. It also includes a horizontally arranged hydraulic cylinder arranged on the outer side of the upper surface of the moving vehicle body, and the piston rod end of the hydraulic cylinder is fixedly connected to the outer wall of the side formwork. On the outer sides of the tops of the side formworks on the left and right sides, an L-shaped connecting plate is respectively fixedly connected, and the L-shaped connecting plates are arranged facing each other.

Specific embodiments

[0017] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model, so as to have a further understanding of the concept of the present utility model, the technical problems to be solved, the technical features constituting the technical solutions, and the technical effects brought about.

[0018] As Figures 1 to 3 shown, a precast T-beam hydraulic formwork device includes a base 1, a base plate 2 is laid on the base 1, and a moving track 3 arranged along the axis direction of the base 1 is provided on each of the left and right sides of the base plate 2. A moving vehicle body 4 is arranged on the moving track 3. A transverse movement groove extending to the side wall of the moving vehicle body 4 close to the base 1 is provided on the moving vehicle body 4, and a vertically arranged side formwork 6 is arranged in the transverse movement groove; it also includes a horizontally arranged hydraulic cylinder 7 arranged on the outer side of the upper surface of the moving vehicle body 4, and the piston rod end of the hydraulic cylinder 7 is fixedly connected to the outer wall of the side formwork 6; an L-shaped connecting plate is respectively fixedly connected to the outer sides of the tops of the side formworks 6 on the left and right sides, and the L-shaped connecting plates are arranged facing each other; an installation plate 9 extending outward is further provided at the top of the L-shaped connecting plate, and a plurality of vertically arranged driving motors 10 are fixedly arranged on the installation plate 9 at equal intervals along the axis direction of the base plate. A horizontal reinforcing bar 11 is fixed on the output shaft of the driving motor 10, and overlapping hooks 12 that can be hooked to each other are arranged at the ends of the horizontal reinforcing bars 11 on the two side formworks 6.

[0019] The working principle of the device of the utility model is as follows: The hydraulic formwork mainly includes a hydraulic cylinder 7 and side formworks 6. The piston rod ends of the hydraulic cylinders 7 extend inwards from the outside of both sides, driving the side formworks 6 on both sides to close towards the middle, so as to quickly realize the approach and closing of the side formworks. Then, start the driving motor 10 to make the horizontal reinforcing bars 11 on both sides at the same position move towards the central axis direction of the base plate 2, so that the overlapping hooks 12 overlap with each other, and the position of the side formwork 6 is reinforced, avoiding the impact of the poured concrete during the pouring process causing the side formworks 6 on both sides to fall outwards, effectively ensuring the reinforcement and shaping of the side formwork 6 of the device of the utility model and facilitating the subsequent pouring operation. When demoulding is required after pouring is completed, start the driving motor 10 to rotate in the reverse direction to make the overlapping hooks 12 unhook, and then drive the side formwork 6 to retract through the hydraulic cylinder 7 to complete the demoulding process. Then, use the moving vehicle body 4 to move along the moving track 3 to transport the side formwork 6 to the next pouring stage to be carried out, avoiding the scattered assembly and disassembly of the formwork.

[0020] As a preferred embodiment, it further includes a secondary vehicle body 13 arranged on the base plate 2. An installation box 14 is fixed on the secondary vehicle body 13. The installation box 14 includes an upper box body and a lower box body. A demoulding agent box 15 is arranged at the top of the upper box body. A water pump 16 is arranged in the upper box body. The water inlet of the water pump 16 is connected to the bottom of the demoulding agent box 15. The water outlet of the water pump 16 passes through the side wall of the installation box 14 and is connected to a vertically arranged spray pipe 17 outside the installation box 14. An oil spray head 18 facing the side formwork 6 and the base plate 2 is arranged on the spray pipe 17.

[0021] In this embodiment, a structure for a rapid spraying demoulding machine is provided. Specifically, a demoulding agent is stored in the demoulding agent box 15. The water pump 16 pumps the demoulding agent out of the demoulding agent box 15 and pumps it into the spray pipe 17 outside the installation box 14. The oil spray head 18 on the spray pipe 17 sprays the demoulding agent onto the side formwork 6. As the secondary vehicle body 13 travels along the axis direction of the base 1 on the base plate 2, the side formworks 6 on both sides are integrally sprayed completely, quickly completing the spraying and brushing process of the demoulding agent, effectively avoiding manual application of the demoulding agent, reducing the labor intensity of construction workers and ensuring the spraying effect of the demoulding agent at the same time. It should be noted that since the steel reinforcement cage usually needs to be hoisted inside the T-beam, the above-mentioned secondary vehicle body 13 needs to complete the spraying of the demoulding agent before the hoisting and binding of the steel reinforcement cage to avoid the smooth movement of the secondary vehicle body 13 being blocked by the steel reinforcement cage.

[0022] As a further embodiment, an air compressor pump 19 is arranged in the lower box body. The air compressor pump 19 is provided with an air pipe 20 facing the traveling direction of the secondary vehicle body 13. The air pipe 20 passes through the side wall of the installation box 14 and is connected to an air jet head. The air jet head is inclined towards the base plate 2 and the side formwork 6 in the traveling direction of the secondary vehicle body 13.

[0023] In this embodiment, the purpose of setting the air compression pump 19 is to spray high-pressure gas towards the base plate 2 and the side formwork 6 in front of the secondary car body 13 through the air pipe 20 and the jet head. With the help of the high-speed air flow, it can assist in surface cleaning of the base plate 2 and the side formwork 6, avoiding the influence of residual debris on the appearance of the precast T-beam after pouring.

[0024] As a preferred embodiment, a triangular reinforcing plate is also provided at the connection between the L-shaped connecting plate and the side formwork 6.

[0025] In this embodiment, the function of setting the reinforcing plate is to increase the connection strength between the L-shaped connecting plate and the side formwork 6.

[0026] As a preferred embodiment, the height of the lower surface of the side formwork 6 is lower than the height of the upper surface of the base plate 2, and a seepage-proof cushion layer is provided at the overlapping part of the side formwork 6 and the base plate 2.

[0027] In this embodiment, a specific positional relationship between the side formwork 6 and the base plate 2 is provided. Among them, the height of the lower surface of the side formwork 6 is lower than the height of the upper surface of the base plate 2, which can ensure that the side formwork 6 abuts against the base plate 2 under the action of the hydraulic cylinder 7, and cooperate with the seepage-proof cushion layer to effectively ensure the sealing degree between the side formwork 6 and the base plate 2, effectively avoiding slurry leakage.
