Description

Technical Field

[0001] The present invention relates to the technical field of prefabrication of bridge beam structures, and specifically to a combined connection type concrete T-beam construction device. Background Technique

[0002] With the rapid development of China's economy, the construction volume and construction capacity of large-scale building transportation projects are also gradually increasing. During the construction of large bridges, prestressed concrete continuous T-beams are often used for construction, which has a relatively fast construction speed and high safety performance.

[0003] When pouring the combined connection type T-beam, a comb formwork is used to tightly fit the flange steel bar framework to close the flow channel of the concrete during pouring, reduce the risk of slurry leakage at the flange edge, and avoid defects such as honeycombing and pockmarks caused by slurry loss. When disassembling the comb formwork, due to the solidification of the concrete, the comb formwork will adhere to both sides of the T-beam and is difficult to disassemble. When disassembling the formwork, workers usually use hammers to strike the comb formwork to loosen the adhered parts, or use crowbars to insert from the formwork joints for disassembly. The labor intensity is large while the disassembly efficiency is low, and the force of manual formwork disassembly by workers is not easy to control, and it is easy to damage the concrete edges during formwork disassembly, affecting the finished product quality of the concrete T-beam. Summary of the Invention

[0004] The purpose of the present invention is to provide a combined connection type concrete T-beam construction device to solve the problem that the flange comb formwork on both sides is difficult to remove during the construction of T-beams in the prior art.

[0005] To achieve the above purpose, the present invention provides the following technical solution: A combined connection type concrete T-beam construction device, including a T-beam main body and a plurality of comb formworks adhered to the outside of the T-beam main body when the T-beam main body is poured. A plurality of distribution bars are formed on both sides of the T-beam main body. A device main body is provided on one side of one of the comb formworks. Two pipe plates are fixedly connected to the top of the device main body. A first limit plate is fixedly connected between the rear ends of the two pipe plates. A striking rod is provided at the bottom of the first limit plate. A support plate is provided at the rear side of the device main body. Two support wheels are provided at the front side of the device main body.

[0006] Preferably, both ends of the top of the striking rod are fixedly connected with first sliding rods. The top ends of the two first sliding rods penetrate through the first limit plate and are slidably connected to the first limit plate. First springs are sleeved on the outside of the two first sliding rods. The two ends of the two first springs are respectively in contact with the striking rod and the first limit plate.

[0007] Preferably, a second sliding rod is fixedly connected to the top of the knocking rod. The top of the second sliding rod penetrates through the first limiting plate and is slidably connected to the first limiting plate. The top of the second sliding rod is fixedly connected to a second limiting plate. A first motor is fixedly connected to the top of the device body. The output end of the first motor is fixedly connected to a cam. When the cam rotates, it drives the knocking rod to move up and down in cooperation with the first spring to continuously knock the comb template, so as to separate the comb template from the concrete of the T-beam body, eliminating the need for manual knocking and removal, and reducing the labor burden of workers.

[0008] Preferably, a fixing rod is arranged inside the device body. A sliding groove adapted to the fixing rod is formed at the rear side of the device body. The fixing rod is slidably connected inside the sliding groove. The rear side of the fixing rod is fixedly connected to a support plate. Second springs are fixedly connected to the upper and lower parts of the front end of the fixing rod respectively. One ends of the two second springs far away from the fixing rod are fixedly connected to the upper and lower inner walls of the device body respectively.

[0009] Preferably, a moving plate is slidably connected inside the device body. A positioning groove is formed inside the moving plate. Two moving blocks are slidably connected inside the positioning groove. Connecting plates are fixedly connected to the rear sides of the two moving blocks respectively. One sides of the two connecting plates are fixedly connected to two support wheels respectively. A third spring is fixedly installed between the tops of the two moving blocks. A limiting sliding groove adapted to the two moving blocks is formed at the bottom wall inside the device body. When the two moving blocks leave the device body from inside the limiting sliding groove, the two moving blocks move away from each other under the action of the third spring. At this time, the positions of the two moving blocks correspond to the inner side positions of the distribution bars.

[0010] Preferably, a transmission plate is fixedly connected to one side of the top of the moving plate. A threaded rod is rotatably installed inside the device body. The threaded rod penetrates through the transmission plate and is in threaded connection with the transmission plate. A second motor is fixedly connected to one side of the device body. The output end of the second motor is fixedly connected to the threaded rod. During operation, the second motor drives the moving blocks to move outwards from inside the device body. After the support wheels contact the distribution bars, they push the device body to move backwards, so that the support plate contacts the comb template. At this time, the support wheels and the support plate fix the device body between the comb template and the distribution bars.

[0011] Preferably, guide plates are fixedly connected to both sides of the device body. Two rotating wheels are rotatably installed between the two guide plates and the device body respectively. A handle is fixedly connected to the top of the T-beam body.

[0012] Compared with the prior art, the beneficial effects of the present invention are:

[0013] 1. In this application, when the second motor operates, it drives the threaded rod to rotate, causing the threaded rod to drive the support wheel to move forward and fit with the distribution bars. Subsequently, it pushes the main body of the device to move, making the support plate at the rear of the main body of the device closely adhere to the comb template. With the support plate and the support wheel, it is convenient for workers to fix the main body of the device on one side of the comb template. At this time, the knocking rod is directly above the comb template. When the first motor operates, it drives the knocking rod to strike the comb template, thereby separating the comb template from the T-beam main body, reducing the labor burden of workers and improving the working efficiency of demolding the T-beam main body.

[0014] 2. In this application, when working, the first motor drives the knocking rod to strike the comb template, thereby quickly separating the comb template from the T-beam main body, preventing excessive knocking force on the template during manual demolding and causing damage to the concrete edges and corners of the T-beam main body.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0020] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the present invention, rather than all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0021] Embodiment: As Figure 1 - Figure 4As shown in the figure, the present invention provides a technical solution for a combined connection type concrete T-beam construction device, including a T-beam main body 1 and a plurality of comb templates 2 adhered to the outer side of the T-beam main body 1 when the T-beam main body 1 is poured. A plurality of distribution bars 3 are formed on both sides of the T-beam main body 1. A device main body 4 is arranged on one side of one of the comb templates 2. Two pipe plates 5 are fixedly connected to the top of the device main body 4. A first limiting plate 6 is fixedly connected between the rear ends of the two pipe plates 5. A knocking rod 7 is arranged at the bottom of the first limiting plate 6. A support plate 14 is arranged at the rear side of the device main body 4, and two support wheels 25 are arranged at the front side of the device main body 4.

[0022] Both ends of the top of the knocking rod 7 are fixedly connected with first sliding rods 8. The top ends of the two first sliding rods 8 penetrate through the first limiting plate 6 and are slidably connected with the first limiting plate 6. First springs 9 are sleeved on the outer sides of the two first sliding rods 8. The two ends of the two first springs 9 are respectively in contact with the knocking rod 7 and the first limiting plate 6.

[0023] A second sliding rod 10 is fixedly connected to the top of the knocking rod 7. The top of the second sliding rod 10 penetrates through the first limiting plate 6 and is slidably connected with the first limiting plate 6. A second limiting plate 11 is fixedly connected to the top end of the second sliding rod 10. A first motor is fixedly connected to the top of the device main body 4. The output end of the first motor is fixedly connected with a cam 12. When the cam 12 rotates, it cooperates with the first spring 9 to drive the knocking rod 7 to move up and down to continuously knock the comb template 2, so that the comb template 2 is separated from the concrete of the T-beam main body 1, and there is no need for manual beating and demolition, reducing the labor burden of workers.

[0024] A fixed rod 13 is arranged inside the device main body 4. A chute adapted to the fixed rod 13 is opened at the rear side of the device main body 4. The fixed rod 13 is slidably connected inside the chute. The rear side of the fixed rod 13 is fixedly connected to the support plate 14. Second springs 15 are fixedly connected to the upper and lower parts of the front end of the fixed rod 13. The two ends of the two second springs 15 far from the fixed rod 13 are respectively fixedly connected to the upper and lower inner walls of the device main body 4.

[0025] A moving plate 18 is slidably connected inside the device main body 4. A positioning groove 21 is opened inside the moving plate 18. Two moving blocks 22 are slidably connected inside the positioning groove 21. Connecting plates 24 are fixedly connected to the rear sides of the two moving blocks 22. One side of each of the two connecting plates 24 is fixedly connected to one of the two support wheels. A third spring 23 is fixedly installed between the top ends of the two moving blocks 22. A limiting chute 26 adapted to the two moving blocks 22 is opened at the bottom wall inside the device main body 4. When the two moving blocks 22 leave the device main body 4 from inside the limiting chute 26, the two moving blocks 22 move away from each other under the action of the third spring 23. At this time, the positions of the two moving blocks 22 correspond to the inner side positions of the distribution bars 3.

[0026] One side of the top of the moving plate 18 is fixedly connected to a transmission plate 19. A threaded rod 20 is rotatably installed inside the device main body 4. The threaded rod 20 penetrates through the transmission plate 19 and is in threaded connection with the threaded rod 20. One side of the device main body 4 is fixedly connected to a second motor. The output end of the second motor is fixedly connected to the threaded rod 20. During operation, the second motor drives the moving block 22 to move outwards from inside the device main body 4. After the support wheel 25 contacts the distribution bar 3, it pushes the device main body 4 to move backward, so that the support plate 14 contacts the comb formwork 2. At this time, the support wheel 25 and the support plate 14 fix the device main body 4 between the comb formwork 2 and the distribution bar 3.

[0027] Guide plates 16 are fixedly connected to both sides of the device main body 4. Two rotating wheels 17 are rotatably installed between the two guide plates 16 and the device main body 4. A handle 27 is fixedly connected to the top of the T-beam main body 1.

[0028] It should be noted that the present invention is a combined connection type concrete T-beam construction device. When in use, the worker places the knocking rod 7 on the top of the comb formwork 2 through the handle 27. At this time, the device main body 4 is located between the two distribution bars 3. The rotating wheels 17 on both sides of the device main body 4 are placed above the two distribution bars 3 to support the device main body 4. Subsequently, the second motor works to drive the threaded rod 20 to rotate. The threaded rod 20 drives the moving plate 18 to move forward through the transmission plate 19. The two moving blocks 22 are always in contact with both sides of the limit chute 26 under the action of the elastic force of the third spring 23. At this time, the two moving blocks 22 move along the limit chute 26 and move away from each other. When the two moving blocks 22 leave the limit chute 26, at this time, the two moving blocks 22 drive the two support wheels 25 to enter the inner sides of the distribution bars 3 on both sides of the device main body 4. The threaded rod 20 continues to drive the moving plate 18 to move so that the moving block 22 fits with the distribution bar 3. When the support wheel 25 fits with the inner side of the distribution bar 3, the moving plate 18 cannot move. The threaded rod 20 continues to rotate to push the device main body 4 towards the direction of the comb formwork 2. When the support plate 14 at the rear of the device main body 4 is in close contact with the comb formwork 2, the second motor stops working. At this time, the device main body 4 is fixed on one side of the comb formwork 2 through the support wheel 25 and the support plate 14, and at the same time, the knocking rod 7 is located directly above the comb formwork 2.

[0029] Subsequently, the first motor starts to work to drive the cam 12 to rotate. When the main body 4 of the fixing device knocks the knocking rod 7 against the top of the comb template 2, the knocking rod 7 compresses the first spring 9. The second limiting plate 11 is fixed to the top of the knocking rod 7 through the second sliding rod 10. At this time, there is a certain distance between the top of the second limiting plate 11 and the cam 12. When the cam 12 rotates, the protrusion of the cam 12 contacts the second limiting plate 11. At this time, the cam 12 drives the second limiting plate 11 to move upward, so that the knocking rod 7 moves upward to compress the first spring 9. The cam 12 continues to rotate. When the protrusion of the cam 12 does not contact the second limiting plate 11, the knocking rod 7 is bounced towards the comb template 2 under the action of the elastic force of the first spring 9. The knocking rod 7 driven by the cam 12 continuously knocks the comb template 2, so that the concrete adhesion part between the comb template 2 and the T-beam main body 1 becomes loose. At this time, the comb template 2 is separated from the T-beam main body 1. The support plate 14 is slidably connected to the rear side of the device main body 4, and second springs 15 are fixedly connected between the front end of the support plate 14 and the upper and lower walls of the device main body 4, so that when the knocking rod 7 knocks the comb template 2, the support plate 14 can vibrate with the comb template 2 and will not affect the demoulding work of the comb template 2.

[0030] After the comb template 2 is separated from the T-beam main body 1, at this time, the first motor works to drive the two moving blocks 22 to re-enter the limit sliding grooves 26, so as to release the limit of the support plate 14 and the support wheels 25 on the device. At this time, the worker can remove the next comb template 2. When the support plate 14 does not contact the comb template 2, the comb template 2 falls from one side of the T-beam main body 1 under the action of gravity. At this time, the worker can collect the separated comb template 2.

[0031] For those skilled in the art, it is obvious that the present invention is not limited to the details of the above exemplary embodiments, and can be implemented in other specific forms without departing from the spirit or basic characteristics of the present invention. Therefore, from any point of view, the embodiments should be regarded as exemplary and non-limiting.
