Description

Technical Field

[0001] The invention belongs to the technical field of T-beam processing, and particularly relates to a self-propelled synchronous hydraulic T-beam template device and method. Background Art

[0002] With the rapid development of my country's economy and the implementation of highway network planning and construction, my country has ushered in another peak period in highway construction. In highway construction, factory prefabrication of bridge beams and slabs is an important measure to speed up bridge construction progress and save investment. As a result, the number of bridge prefabrication sites has also increased rapidly. Formwork is a common structure for prefabricating T-beams and other beams and slabs. Among them, hydraulic formwork has obvious advantages over ordinary steel formwork. In order to improve product quality, T-beam prefabricated hydraulic formwork has stood out in actual production applications. It has obvious advantages in safety, quality, efficiency and economy, and has been widely promoted and applied.

[0003] Self-propelled hydraulic formwork is a fixed-length formwork. The hydraulic T-beam formwork consists of five major parts: formwork system, support and reinforcement system, hydraulic system, walking system, and basic pedestal. The overall formwork in the formwork system is assembled from small formworks.

[0004] However, in order to ensure the smoothness and flatness of the finished T-beam surface, the existing hydraulic T-beam formwork often needs to be manually polished by a grinder on the raised positions on the surfaces of the two side formworks. When there are many raised positions, the labor intensity of the workers is undoubtedly increased. In addition, the probability of manual polishing causing wear to the side formwork body is high. In addition, it is inconvenient to apply a release agent to the side formwork surface, which makes it inconvenient to perform subsequent demoulding.

[0019] The present invention also provides a self-propelled synchronous hydraulic T-beam formwork device and method, comprising the following steps:

[0020] S1. When in use, first place the trolley on the track reserved on the site and allow the trolley to move on the track surface. Then the hydraulic T-beam formwork can be assembled on site, or the assembled finished product can be directly hoisted on the mold making site;

[0021] S2. Then, place the steel pedestal in the center between the two side formworks, and then loosen the fastening bolts on the surface of the telescopic adjustment rod between the two side formworks respectively. Then, according to the height of the steel pedestal, start the lifting hydraulic cylinders on both sides synchronously, and use the lifting hydraulic cylinders to drive the side formwork to move up as a whole, so that the bottom end of the side formwork is level with or slightly lower than the surface of the steel pedestal. Then, start the translation hydraulic cylinder synchronously, and use the translation hydraulic cylinder to drive the two side formworks to move closer to each other until both side formworks are in close contact with the two side surfaces of the steel pedestal.

[0022] S3. Then, the two ends of the two side formworks are sealed to form a sealed chamber between the side formworks and the steel pedestal. Then, concrete can be poured between the two side formworks. After the concrete solidifies and forms, the sealing plates at the ends of the two side formworks can be removed. Then, the translation hydraulic cylinders on both sides are driven to operate so that the side formworks on both sides are moved away from each other to achieve demoulding.

[0023] S4. Finally, the T-beam hydraulic formwork device can be moved to the next pouring point by the walking trolley for pouring;

[0024] S5. Before the next pouring, the operator starts to control the sanding belt to move on the side formwork surface, so as to grind the uneven parts of the side formwork surface. During this process, the air nozzle continuously blows air to the side formwork surface to clean the dust attached to the side formwork surface. At the same time, the cleaning brush can be used to keep the side formwork surface clean.

[0025] S6. After grinding once, while the grinding belt is returning to its original position, the release agent can be sprayed on the surface of the side formwork through the soft liquid discharge head, so that the release agent can be automatically applied to the side formwork without manual operation, saving time and effort. When the grinding belt is returned to its original position, S2 and S3 can be repeated to carry out the next round of T-beam casting.

[0026] Compared with the prior art, the present invention has the following beneficial effects: the present invention has a scientific and reasonable structure and is safe and convenient to use:

[0027] 1. The synchronous hydraulic T-beam formwork assembly is equipped. On the one hand, it can improve the integrity, maneuverability and safety of the T-beam formwork device, which can greatly improve the quality of T-beam prefabrication construction. At the same time, it effectively ensures safety and improves construction efficiency, which has strong promotion value. On the other hand, it shortens the time for formwork installation and removal. After the T-beam is poured, there is no need to remove the formwork before the next T-beam is poured, which effectively avoids the high lifting frequency and safety risks of conventional formwork such as collision and lodging;

[0028] By providing a support frame, side formwork webs, side formwork, transverse I-beams, oblique supports, vertical I-beams, fixed seats, oblique connecting rods, counterweight platforms, guardrails and fixed bosses, when pouring the T-beam, the side formwork on both sides can be controlled to contact with the steel pedestal, so that a sealed chamber is formed between the side formwork and the steel pedestal, and then concrete can be poured into the sealed chamber to complete the pouring of the T-beam, which can improve the integrity, maneuverability and safety of the T-beam formwork device, greatly improve the quality of T-beam prefabrication construction, and effectively ensure safety and improve construction efficiency;

[0029] Furthermore, by using vertical I-beams, rectangular grooves and threaded support columns, after the position of the side formwork is determined, the threaded support columns can be rotated so that the threaded support columns come into contact with the ground, thereby providing a certain support to the side formwork.

[0030] Moreover, through the use of slide rails, sliding seats, translation hydraulic cylinders, lifting hydraulic cylinders and fixed bosses, the relative distance and height between the two side templates can be adjusted according to the size and height of the steel base. It has a wide range of applications and does not require demolding and reinstallation, making it more convenient to use.

[0031] 2. A grinding and dust cleaning component is provided to grind the surface of the side formwork after use to smooth it out, preventing residual concrete from adhering to the surface of the side formwork, ensuring the flatness of the side formwork surface, and thus improving the quality of subsequent T-beam casting. There is no need for manual grinding with a grinder, which on the one hand reduces the labor intensity of workers, and on the other hand helps to ensure the grinding quality;

[0032] By providing a vertical plate, a first screw, a driving motor, an L-shaped movable frame, a sliding plate, a telescopic adjustment rod, a fastening bolt, a limit fixing plate and a grinding belt, before the next round of T-beam casting is carried out, the operation of the driving motor is controlled to drive the first screw to rotate, and the L-shaped movable frame is driven to move by the rotation of the first screw, and the limit fixing plate is driven to move by the movement of the L-shaped movable frame. The cooperation of the limit fixing plate can drive the grinding belt to grind the uneven position of the side template surface during the movement to ensure the flatness of the side template surface;

[0033] In combination with the use of solid connecting plates and cleaning brushes, the movement of the cleaning brushes during grinding can clean up the floating and sinking of the side template surface caused by grinding;

[0034] In conjunction with the use of a hollow connecting plate, an air jet nozzle, a first rotating rod, an extrusion wheel, an elastic rubber airbag, a connecting air pipe, a corrugated hose, an air outlet pipe and an air inlet pipe, during the grinding process, the first rotating rod can be driven to rotate, and then the extrusion wheel can be driven to roll and squeeze on the surface of the elastic rubber airbag, so that the gas in the elastic rubber airbag can be squeezed out and enter the corrugated hose through the air outlet pipe, and finally blown toward the side template through the air jet nozzle, which can assist in cleaning the bristles and improve the cleaning efficiency of the surface of the opposite side template.

[0035] 3. A release agent spraying component is provided, which can automatically apply the release agent to the surface of the opposite template after grinding, eliminating the need for manual application and saving time and effort;

[0036] Through the coordinated use of the release agent holding box, the hollow cylinder, the moving rod, the liquid outlet pipe, the third one-way valve, the liquid inlet pipe, the fourth one-way valve, the hollow porous plate, the soft liquid outlet head, the connecting pipe and the piston, during grinding, the moving rod is driven to move by the movement of the L-shaped moving frame, and the piston is driven to move in the hollow cylinder by the movement of the moving rod, so that the hollow cylinder is in a negative pressure state. At this time, the release agent in the release agent holding box can enter the hollow cylinder through the liquid inlet pipe. In the process of the grinding belt returning to its initial state, the L-shaped moving frame moves in the reverse direction and drives the moving rod to move in the reverse direction. Then, the release agent in the hollow cylinder can be sprayed onto the surface of the side template through the hollow porous plate and the soft liquid outlet head through the action of the piston, thereby realizing spraying the release agent on the side template, without wasting much manpower and saving labor costs.

[0037] And when used in conjunction with a trowel, the release agent on the surface of the side template can be evenly spread, thereby improving the uniformity of the release agent application and facilitating demoulding in the later stage. BRIEF DESCRIPTION OF THE DRAWINGS

The grinding belt 49 can contact the surface of the side template 33 under the action of the limiting fixing plate 48, so that the grinding belt 49 can be used to grind the protrusions formed by demoulding on the surface of the side template 33 to ensure that the surface of the side template 33 is flat and smooth.

[0074] The working principle and use process of the present invention are as follows: first, the walking trolley 2 is placed on the track reserved on the site, and the walking trolley 2 is allowed to move on the track surface. Then, the hydraulic T-beam formwork can be assembled on site, or the assembled finished product can be directly hoisted on the mold making site without frequent disassembly and assembly. This can improve the integrity, maneuverability and safety of the T-beam formwork device, greatly improve the quality of T-beam prefabrication construction, and effectively ensure safety and improve construction efficiency.

[0075] Then, the steel pedestal 1 is placed in the center between the side templates 33 on both sides, and then the fastening bolts 47 on the surface of the telescopic adjustment rod 46 between the two side templates 33 are loosened respectively. Then, according to the height of the steel pedestal 1, the lifting hydraulic cylinders 314 on both sides are synchronously started, and the lifting hydraulic cylinders 314 are used to drive the supporting frame 31 to move upward as a whole. The overall upward movement of the supporting frame 31 then drives the side templates 33 to move upward as a whole, so that the bottom end of the side template 33 is flush with the surface of the steel pedestal 1 or slightly lower than the surface of the steel pedestal 1. Then, the translation hydraulic cylinder 317 is synchronously started, and the translation hydraulic cylinder 317 is used to drive the two side templates 33 to move closer to each other until both side templates 33 are in close contact with the two side surfaces of the steel pedestal 1.

[0076] Then, the two ends of the two side templates 33 are sealed to form a sealed chamber between the side templates 33 and the steel pedestal 1. Then, concrete can be poured between the two side templates 33. After the concrete solidifies and forms, the sealing plates at the ends of the side templates 33 on both sides can be removed. Then, the translation hydraulic cylinders 317 on both sides are driven to operate so that the side templates 33 on both sides are separated from each other to achieve demoulding.

[0077] Then the T-beam hydraulic formwork device can be moved to the next pouring point by the walking trolley 2 for pouring;

[0078] Before the next pouring, the user first starts to tighten the fastening bolts 47 to limit the position of the limiting fixing plate 48 so that the grinding belt 49 can contact the surface of the side formwork 33. Then, the driving motors 43 on both sides are started synchronously to operate. The driving motor 43 drives the first screw 42 to rotate. The rotation of the first screw 42 drives the L-shaped moving frame 44 to move. The movement of the L-shaped moving frame 44 then drives the limiting fixing plate 48 to move accordingly. The movement of the limiting fixing plate 48 can drive the grinding belt 49 to grind the uneven positions on the surface of the side formwork 33 during the movement to ensure the flatness of the surface of the side formwork 33.

[0079] During this process, the movement of the limiting fixing plate 48 can drive the solid connecting plate 410 to move along with it, and the movement of the solid connecting plate 410 can drive the cleaning brush 411 to move on the surface of the side template 33, thereby cleaning the surface of the side template 33 caused by grinding;

[0080] During this process, the L-shaped moving frame 44 moves and can drive the gear 418 to rotate on the surface of the gear plate 419. The rotation of the gear 418 drives the first rotating rod 416 to rotate. The rotation of the first rotating rod 416 drives the extrusion wheel 417 to roll on the surface of the counterweight platform 311. During the rolling process, the extrusion wheel 417 can sequentially squeeze the elastic rubber airbag 420, so that the gas in the elastic rubber airbag 420 close to the side of the extrusion wheel 417 is transmitted in turn through the connecting air pipe 421 along the direction of the extrusion wheel 417, and then transported to the corrugated hose 427 through the air outlet pipe 422 at the end, and then transported to the hollow connecting plate 412 through the corrugated hose 427, and finally sprayed to the surface of the side template 33 through the air nozzle 413, which can assist the cleaning bristles 411 to improve the cleaning efficiency of the surface of the side template 33;

[0081] During this process, the movement of the L-shaped moving frame 44 drives the moving rod 53 to move, and the movement of the moving rod 53 drives the piston 511 to move in the hollow cylinder 52, so that the hollow cylinder 52 is in a negative pressure state. At this time, the release agent in the release agent storage box 51 can enter the hollow cylinder 52 through the liquid inlet pipe 56 for storage;

[0082] When the grinding belt 49 moves to the other side of the side template 33, the grinding work is completed by default. At this time, the driving motor 43 is reversed, and then the first screw 42 is driven to reverse, and the first screw 42 is reversed, and then the L-shaped movable frame 44 is driven to move in the opposite direction. The reverse movement of the L-shaped movable frame 44 can drive the movable rod 53 to move in the opposite direction. The movable rod 53 moves in the opposite direction, and then the release agent in the hollow cylinder 52 can be sprayed onto the surface of the side template 33 through the hollow porous plate 58 and the soft liquid outlet head 59 through the action of the piston 511, thereby spraying the release agent on the side template 33 without wasting much manpower, saving labor costs;

[0083] During this process, since the uneven positions on the surface of the side template 33 have been polished, the reverse movement of the sanding belt 49 can, on the one hand, assist in the secondary polishing of the side template 33, and can polish again the positions that were not polished in the first time, and on the other hand, can evenly spread the release agent sprayed on the surface of the side template 33. In conjunction with the function of the screed plate 512, the release agent can be evenly applied to the surface of the side template 33, which is convenient for subsequent demoulding.

[0084] During this process, as the squeezing wheel 417 rolls in the reverse direction, the elastic rubber airbag 420 can sequentially absorb external air into the elastic rubber airbag 420 through the air inlet pipe 423, so that the elastic rubber airbag 420 is in a filled state again.

[0085] Until the grinding belt 49 returns to its initial position and the drive motor 43 is stopped, the next round of T-beam casting can be carried out without removing the formwork, which effectively avoids the high lifting frequency and safety risks of bumping and falling of conventional formwork, has a wide range of applications, and is relatively convenient to use.

[0086] The present invention also provides a self-propelled synchronous hydraulic T-beam formwork device and a method for using the same, comprising the following steps:

[0087] S1. When in use, first place the trolley 2 on the track reserved on the site and allow the trolley 2 to move on the track surface. Then the hydraulic T-beam formwork can be assembled on site, or the assembled finished product can be directly hoisted on the mold making site;

[0088] S2. Then, the steel pedestal 1 is placed in the center between the side templates 33 on both sides. Then, the fastening bolts 47 on the surface of the telescopic adjustment rod 46 between the two side templates 33 are loosened respectively. Then, according to the height of the steel pedestal 1, the lifting hydraulic cylinders 314 on both sides are synchronously started. The lifting hydraulic cylinders 314 are used to drive the side templates 33 to move upward as a whole, so that the bottom end of the side template 33 is flush with or slightly lower than the surface of the steel pedestal 1. Then, the translation hydraulic cylinder 317 is synchronously started. The translation hydraulic cylinder 317 is used to drive the two side templates 33 to move closer to each other until both side templates 33 are in close contact with the two side surfaces of the steel pedestal 1.

[0089] S3. Then, the two ends of the two side templates 33 are sealed to form a sealed chamber between the side templates 33 and the steel pedestal 1. Then, concrete can be poured between the two side templates 33. After the concrete solidifies and forms, the sealing plates at the ends of the side templates 33 on both sides can be removed. Then, the translation hydraulic cylinders 317 on both sides are driven to operate so that the side templates 33 on both sides are moved away from each other to achieve demoulding.

[0090] S4. Finally, the T-beam hydraulic formwork device can be moved to the next pouring point by the walking trolley 2 for pouring;

[0091] S5. Before the next pouring, the operator starts to control the sanding belt 49 to move on the surface of the side formwork 33, thereby grinding the uneven parts of the side formwork 33. During this process, the air nozzle 413 continuously blows air to the surface of the side formwork 33 to clean the dust attached to the surface of the side formwork 33. At the same time, the cleaning brush 411 can be used to keep the surface of the side formwork 33 clean.

[0092] S6. After grinding once, while the grinding belt 49 is returning to its initial position, the release agent can be sprayed on the surface of the side formwork 33 through the soft liquid discharge head 59, so that the release agent can be automatically applied to the side formwork 33 without manual operation, saving time and effort. When the grinding belt 49 is returned to its initial position, S2 and S3 can be repeated to carry out the next round of T-beam casting.
