Description

A seamless construction method for ultra-long hot-rolled concrete structures Technical Field

[0001] This invention relates to the technical field of seamless construction methods for ultra-long hot-rolled concrete structures, specifically a seamless construction method for ultra-long hot-rolled concrete structures. Background Technology

[0002] With the continuous development of the national economy, more and more high-rise buildings have appeared in cities. These high-rise buildings are constructed using concrete structures, which are composed of materials such as hot-rolled steel bars, cement, expansion agents, sand, stone, and antifreeze agents. Through the use of expansion agents, antifreeze agents, and other materials, the concrete structure can be effectively prevented from cracking due to factors such as drying shrinkage and thermal stress, thus achieving seamless construction of ultra-long hot-rolled concrete structures.

[0003] For example, Chinese Patent (Announcement No.: CN 114232788 A) discloses a seamless construction structure and method for ultra-long concrete structures, including a horizontal plate with vertical plates fixed at both ends. A vibrating plate is slidably installed between the two vertical plates, with the vibrating plate located above the horizontal plate. A drive box is fixed at the bottom of the horizontal plate, and a vibrating rod is slidably installed between the horizontal plate and the drive box. The drive box contains a vibrating component that drives the vibrating rod to move up and down. The top of the vibrating rod is fixedly connected to the vibrating plate, and a compression spring is sleeved on the vibrating rod, causing the concrete slurry to vibrate, increasing the fluidity of the concrete slurry, making the concrete evenly distributed. The vibration causes the concrete slurry particles to fill each other densely and fill the forming template frame, eliminating air bubbles and voids in the concrete slurry, improving the density and flatness of the concrete. No manual operation is required, reducing labor intensity. Electric demolding is quick and convenient.

[0004] However, the aforementioned patent has some shortcomings. Its forming template frame is fixed to the shaking plate through a structure such as connecting rods and limiting rods. The position of the connecting hole on the shaking plate for the connecting rod to pass through is fixed. This makes it inconvenient to change the forming template frame to different sizes, reducing the practicality of the device and limiting its use. Therefore, a seamless construction method for ultra-long hot-rolled concrete structures is proposed to solve the above problems. Summary of the Invention

[0005] To address the shortcomings of existing technologies, this invention provides a seamless construction method for ultra-long hot-rolled concrete structures, which has advantages such as convenient mold replacement. This solves the problems of the aforementioned patents, which are inconvenient to replace molds during use, have low practicality, and are limited in application.

[0006] To achieve the above objectives, the present invention provides the following technical solution: an ultra-long hot-rolled concrete structure, including a rectangular silo, a concrete template placed on the top surface of the rectangular silo, a fixing mechanism for fixing the concrete template on the rectangular silo, and a vibration mechanism for vibrating the concrete inside the concrete template inside the rectangular silo.

[0007] The fixing mechanism includes an active rod rotatably connected to the left side of the rectangular compartment. A rotating plate is fixed to the left end of the active rod. Two active wheels distributed left and right are fixed to the outer peripheral wall of the active rod. Two support plates distributed left and right are fixed to the top surface of the rectangular compartment. A screw is rotatably connected to the opposite side of each of the two support plates. A transmission wheel is fixed to the opposite end of each of the two screws. A belt is provided between the active wheels and the transmission wheels to enable transmission between them. A threaded cylinder is threadedly connected to the outer peripheral wall of the screw. An extrusion plate is fixed to the opposite side of each of the two threaded cylinders. Two guide rods that horizontally penetrate the support plates and are slidably connected to them are fixed to the opposite side of each of the two extrusion plates.

[0008] Furthermore, the vibration mechanism includes a motor fixed to the back of a rectangular chamber, and multiple circular rods equidistantly distributed on the left and right sides are rotatably connected between the front and rear inner walls of the rectangular chamber. The rear end of the rightmost circular rod is fixed to the output shaft of the motor. Gears are fixed on the outer peripheral wall of the circular rod, and two adjacent gears mesh with each other. Multiple circular plates distributed on the front and back sides are fixed on the outer peripheral wall of the circular rod. Multiple rotating shafts are fixed on the front of the circular plates. Connecting rods are rotatably connected to the outer peripheral wall of the rotating shafts. A striking hammer is fixed to the bottom end of the connecting rod.

[0009] Furthermore, a controller is fixed to the front of the rectangular compartment, and four foot pads are fixed to the bottom of the rectangular compartment.

[0010] Furthermore, an anti-slip sleeve is fixed on the outer peripheral wall of the rotating plate, two rectangular holes for the belt to pass through are opened on the top surface of the rectangular compartment, two guide holes for the guide rod to pass through and slide with it are opened on the left side of the support plate, multiple anti-slip protrusions are fixed on the opposite side of the two extrusion plates, and a limit block is fixed on the end of the guide rod away from the extrusion plate.

[0011] Furthermore, the concrete template is located between the two extrusion plates, and the multiple anti-slip protrusions are distributed in a rectangular array at equal intervals on the side of the extrusion plate facing the concrete template. The guide hole is fitted with the guide rod with a clearance.

[0012] Furthermore, the right end of the drive rod is rotatably connected to the inner right wall of the rectangular compartment, the two drive wheels are respectively positioned vertically opposite to the two transmission wheels, and the threads of the two screws are in opposite directions.

[0013] Furthermore, multiple circular plates on two adjacent circular rods are distributed at intervals, and multiple rotating shafts are distributed equidistantly along the circumference of the circular plates.

[0014] Furthermore, the striking hammer is a rubber hammer, the length of the connecting rod is equal to the distance between the topmost rotating shaft and the rectangular chamber, and the plurality of circular rods are all located directly below the concrete formwork.

[0015] In addition, a seamless construction method for ultra-long hot-rolled concrete structures is proposed, including the following steps:

[0016] Step 1: Select a concrete formwork of appropriate size and place it on the top surface of the rectangular silo;

[0017] Step 2: Rotate the rotating plate to fix the concrete formwork in place by the fixing mechanism;

[0018] Step 3: Place the hot-rolled steel bars into the concrete formwork and pour the concrete into the concrete formwork. Control the vibration mechanism through the controller to increase the fluidity of the concrete slurry and make the concrete evenly distributed in the concrete formwork.

[0019] Step 4: Rotate the rotating plate in the opposite direction to release the fixing mechanism from the concrete formwork, remove the concrete formwork and set it aside to wait for the concrete to solidify.

[0020] Step 5: Select a spare concrete formwork and repeat the above operation. After the concrete inside the adjacent concrete formwork has solidified, demold the formwork to obtain an ultra-long hot-rolled seamless concrete structure.

[0021] Compared with the prior art, the technical solution of this application has the following beneficial effects:

[0022] 1. This seamless construction method for ultra-long hot-rolled concrete structures involves pouring concrete using a concrete formwork for shaping. The formwork is fixed to a rectangular silo by a fixing mechanism. This mechanism facilitates the disassembly and replacement of the formwork with different sizes, reducing the limitations of the device and improving its practicality. Furthermore, it allows the formwork to be removed after pouring and set aside to allow for concrete curing, facilitating the use of spare formwork during construction and increasing the device's utilization rate, making it easier to promote and apply.

[0023] 2. This seamless construction method for ultra-long hot-rolled concrete structures utilizes a vibration mechanism to continuously strike the inner top wall of the rectangular formwork during concrete pouring. This vibration is transmitted into the formwork, increasing the fluidity of the concrete, resulting in a more uniform concrete distribution. It also eliminates air bubbles and voids in the concrete slurry, preventing cracks in the concrete structure and achieving a seamless construction effect. Attached Figure Description

Detailed Implementation

[0030] 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.

[0031] Please refer to Figures 1-4. This embodiment describes an ultra-long hot-rolled concrete structure, including a rectangular silo 1. A concrete formwork 2 is placed on the top surface of the rectangular silo 1. A fixing mechanism 3 is provided on the rectangular silo 1 to fix the concrete formwork 2. During use, concrete is poured and shaped using the concrete formwork 2. The concrete formwork 2 is fixed to the rectangular silo 1 by the fixing mechanism 3. The fixing mechanism 3 facilitates the disassembly and replacement of the concrete formwork 2 with different sizes, reducing the limitations of the device and improving its practicality. It also allows the concrete formwork 2 to be removed after pouring and placed aside to wait for the concrete to solidify, facilitating the use of spare concrete formwork 2 during construction, increasing the utilization rate of the device, and making it easier to promote its use. The rectangular silo 1 is equipped with a vibration mechanism for vibrating the concrete inside the concrete formwork 2. 4. When pouring concrete into the concrete formwork 2, the vibration mechanism 4 continuously strikes the inner top wall of the rectangular chamber 1, thereby transmitting vibration into the concrete formwork 2, increasing the fluidity of the concrete inside the concrete formwork 2, making the concrete distribution more uniform, eliminating air bubbles and voids in the concrete slurry, avoiding cracks in the concrete structure, and achieving a seamless construction effect. A controller 5 is fixed on the front of the rectangular chamber 1, and four foot pads 6 are fixed on the bottom of the rectangular chamber 1. It should be noted that the control method of this application is controlled by the controller 5. The control circuit of the controller 5 can be implemented by simple programming by those skilled in the art. The power supply is also common knowledge in the art. Furthermore, this application is mainly used to protect mechanical devices, so the control method and circuit connection will not be explained in detail here.

[0032] The fixing mechanism 3 includes an active rod 301 rotatably connected to the left side of the rectangular chamber 1. A rotating plate 302 is fixed to the left end of the active rod 301. Two driving wheels 303, arranged left and right, are fixed to the outer peripheral wall of the active rod 301. Two support plates 304, arranged left and right, are fixed to the top surface of the rectangular chamber 1. In use, a concrete template 2 of appropriate size is selected and placed on the top surface of the rectangular chamber 1. The rotating plate 302 is rotated, which drives the active rod 301 to rotate. The active rod 301 drives the two driving wheels 303 to rotate. Screws 305 are rotatably connected to opposite sides of the two support plates 304. The threads of the two screws 305 are opposite in direction. A transmission wheel 306 is fixed to the opposite ends of the two screws 305. A transmission wheel 306 is provided between the driving wheel 303 and the transmission wheel 306 to facilitate transmission between them. The belt 307 is dynamically connected, and the outer peripheral wall of the screw 305 is threaded with a threaded cylinder 308. On the opposite side of the two threaded cylinders 308, an extrusion plate 309 is fixed. On the opposite side of the two extrusion plates 309, two guide rods 310 are fixed and slidably connected to the horizontally penetrating support plate 304. The two drive wheels 303 drive the two transmission wheels 306 to rotate synchronously and in the same direction through the belt 307. The two transmission wheels 306 drive the two screws 305 to rotate synchronously and in the same direction. Since the threads of the two screws 305 are opposite, the two screws 305 push the threaded cylinders 308 to move relative to the guide rods 310, thereby causing the two extrusion plates 309 to press the concrete formwork 2 for fixation. Then, some hot-rolled steel bars are placed in the concrete formwork 2, and concrete can be poured.

[0033] In this embodiment, an anti-slip sleeve 311 is fixed on the outer peripheral wall of the rotating plate 302. The anti-slip sleeve 311 facilitates the operation of rotating the active rod 301. The top surface of the rectangular chamber 1 has two rectangular holes 312 for the belt 307 to pass through. The left side of the support plate 304 has two guide holes 313 for the guide rod 310 to pass through and slide with it. Multiple anti-slip protrusions 314 are fixed on the opposite side of the two extrusion plates 309. The concrete template 2 is located between the two extrusion plates 309. The multiple anti-slip protrusions 314 are distributed in a rectangular array at equal intervals on the side of the extrusion plate 309 facing the concrete template 2. The anti-slip protrusions 314 help to increase the friction between the extrusion plate 309 and the concrete template 2, thereby improving the stability of the fixation. A limit block 315 is fixed at the end of the guide rod 310 away from the extrusion plate 309. The guide hole 313 is clearance-fitted with the guide rod 310. The limit block 315 prevents the guide rod 310 from disengaging from the guide hole 313 and causing inconvenience.

[0034] The right end of the drive rod 301 is rotatably connected to the inner right wall of the rectangular compartment 1, and the two drive wheels 303 are respectively positioned vertically opposite to the two transmission wheels 306.

[0035] Please refer to Figures 2 and 5. In this embodiment, the vibration mechanism 4 includes a motor 401 fixed to the back of a rectangular chamber 1. Multiple circular rods 402, equidistantly distributed from left to right, are rotatably connected between the front and rear inner walls of the rectangular chamber 1. The rear end of the rightmost circular rod 402 is fixed to the output shaft of the motor 401. Gears 403 are fixed to the outer peripheral wall of the circular rod 402, with adjacent gears 403 meshing. Multiple circular plates 404, distributed front to back, are fixed to the outer peripheral wall of the circular rod 402. When concrete is poured into the concrete formwork 2, the motor 401 is started, driving the rightmost circular rod 402 to rotate. The rightmost circular rod 402 then transmits power to the left via the gears 403. The circular rod 402 on the left side rotates synchronously, and the circular rod 402 drives the circular plate 404 to rotate. Multiple rotating shafts 405 are fixed on the front of the circular plate 404. A connecting rod 406 is rotatably connected to the outer peripheral wall of the rotating shaft 405. A hammer 407 is fixed at the bottom end of the connecting rod 406. Furthermore, the circular plate 404 causes the multiple rotating shafts 405 to revolve around the circular rod 402. When the circular rod 402 reaches a certain speed, the connecting rod 406 will be perpendicular to the circular rod 402. At this time, the hammer 407, which has rotated to the top, will strike the inner top wall of the rectangular chamber 1 and generate vibration, so as to make the concrete in the concrete formwork 2 more evenly distributed and eliminate air bubbles and voids in the concrete slurry.

[0036] In this embodiment, multiple circular plates 404 are distributed at intervals on two adjacent circular rods 402, multiple rotating shafts 405 are distributed at equal intervals along the circumference of the circular plates 404, the striking hammer 407 is a rubber hammer, the length of the connecting rod 406 is equal to the distance between the topmost rotating shaft 405 and the rectangular chamber 1, and the multiple circular rods 402 are all located directly below the concrete formwork 2.

[0037] In addition, a seamless construction method for ultra-long hot-rolled concrete structures is proposed, including the following steps:

[0038] Step 1: Select a concrete formwork 2 of appropriate size and place it on the top surface of the rectangular chamber 1;

[0039] Step 2: Rotate the rotating plate 302 to fix the concrete formwork 2 with the fixing mechanism 3;

[0040] Step 3: Place the hot-rolled steel bars into the concrete formwork 2 and pour the concrete into the concrete formwork 2. Control the vibration mechanism 4 through the controller 5 to vibrate, increase the fluidity of the concrete slurry, and make the concrete evenly distributed in the concrete formwork 2.

[0041] Step 4: Rotate the rotating plate 302 in the opposite direction to release the fixing mechanism 3 from fixing the concrete formwork 2, remove the concrete formwork 2 and place it aside to wait for the concrete to solidify.

[0042] Step 5: Select spare concrete formwork 2 and repeat the above operation. After the concrete inside the adjacent concrete formwork 2 has solidified, demold to obtain an ultra-long hot-rolled seamless concrete structure.

[0043] The working principle of the above embodiments is as follows:

[0044] (1) When using it, select a concrete template 2 of appropriate size and place it on the top surface of the rectangular silo 1. Rotate the rotating plate 302. The rotating plate 302 drives the active rod 301 to rotate. The active rod 301 drives the two active wheels 303 to rotate. The two active wheels 303 drive the two transmission wheels 306 to rotate synchronously and in the same direction through the belt 307. The two transmission wheels 306 drive the two screws 305 to rotate synchronously and in the same direction. Since the threads of the two screws 305 are opposite, the two screws 305 push the threaded cylinder 308 to move relative to the guide rod 310, thereby causing the two extrusion plates 309 to press the concrete template 2 for fixation. Then, place some hot-rolled steel bars into the concrete template 2, and then pour concrete.

[0045] (2) After concrete is poured into the concrete formwork 2, the motor 401 is started. The motor 401 drives the rightmost circular rod 402 to rotate. The rightmost circular rod 402 is transmitted to the left through the gear 403, so that the left circular rod 402 rotates synchronously. The circular rod 402 drives the circular plate 404 to rotate. The circular plate 404 causes multiple rotating shafts 405 to revolve around the circular rod 402. When the circular rod 402 reaches a certain speed, the connecting rod 406 will be perpendicular to the circular rod 402. At this time, the hammer 407, which has rotated to the top, will strike the inner top wall of the rectangular chamber 1 and generate vibration, so that the concrete in the concrete formwork 2 is distributed more evenly and the air bubbles and voids in the concrete slurry are eliminated.
