Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of surface roughening of composite slabs, specifically to a surface roughening device for prefabricated composite slabs that is easy to adjust. Background Technology
[0002] When pouring reinforced concrete into precast composite slabs, the surface needs to be roughened. A search revealed Chinese patent CN217257114U, which discloses a roughening device for precast composite slabs, belonging to the field of composite slab technology. The device includes support legs on both sides of the composite slab conveyor belt, with a top plate fixedly connected to the top of each support leg, and a roughening mechanism fixedly connected to the bottom of the top and bottom via an adjustment mechanism. In this invention, when the composite plate needs to be roughened, the first fixing bolt can be loosened to separate it from the internal hinge shaft, and the fixing seat can be pulled to move outside the hinge shaft to adjust the relative distance between the roughening plates on both sides. This allows the roughening plates to be staggered and fixed on both sides of the pre-embedded reinforcing bars, adapting to the need for staggered roughening adjustment in the pre-embedded area of the composite plate's reinforcing bars, improving the durability of the roughening plates and brush strips. When the bottom conveyor belt moves the composite plate, the roughening plates create roughening grooves on the surface of the composite plate, and the slurry at the joint is swept and blocked by the brush strip on one side, improving the uniformity of roughening. However, when this roughening device is in use, after the brush strip performs roughening work, the working surface of the brush strip will be covered with reinforced concrete, and it cannot be cleaned in time during continuous work, causing the reinforced concrete on the brush strip to solidify and become difficult to clean. This results in a large roughening space in subsequent work, thus reducing the efficiency of the device. Utility Model Content
[0003] To address the shortcomings of existing technologies, this utility model provides an easily adjustable surface roughening device for precast composite slabs. This solves the problem that during the roughening process, reinforced concrete adheres to the working surface of the brush strips after roughening, and this adhesion cannot be cleaned promptly during continuous operation. This leads to the concrete solidifying on the brush strips, making cleaning difficult and resulting in a larger roughening area in subsequent operations, thus reducing the device's efficiency.
[0004] To achieve the above objectives, this utility model provides the following technical solution: a precast composite slab surface roughening device that is easy to adjust, comprising a U-shaped frame and scrapers. A rotating rod is rotatably connected inside the U-shaped frame. A rotary motor is fixedly installed on the right side wall of the U-shaped frame. The output shaft of the rotary motor is fixedly connected to the end of the rotating rod through the inside of the side wall of the U-shaped frame. Roughening plates are fixedly installed at equal intervals on the rod wall. A movable plate is slidably connected inside the U-shaped frame. Multiple scrapers are provided and fixedly installed at equal intervals on the bottom surface of the movable plate. Adjacent scrapers are respectively arranged on both sides of the roughening plates and respectively abut against the side wall of the roughening plates.
[0005] Preferably, the two side walls inside the U-shaped frame are provided with limiting grooves, and the two ends of the movable plate are respectively slidably connected to the inside of the limiting grooves. The two side walls of the movable plate are in contact with the side walls inside the limiting grooves, so as to stabilize the position of the movable plate and prevent the scraper from being misaligned during installation.
[0006] Preferably, the movable plate is internally threaded with a fixing bolt, the length of which is greater than the width of the movable plate. The fixing bolt is connected to the side wall of the limiting groove through the internal thread of the movable plate, thereby enabling convenient installation and removal of the movable plate.
[0007] Preferably, limit plates are symmetrically arranged below the U-shaped frame. The limit plates are slidably connected to the inside of the two side walls of the U-shaped frame. A support seat is fixedly installed at the bottom of each limit plate. A screw is fixedly connected to the top surface of each support seat. Threaded tubes are rotatably connected to the inside of the two side walls of the U-shaped frame. The screws are threadedly connected to the inside of the threaded tubes. A reciprocating motor is symmetrically fixedly installed on the top surface of the U-shaped frame. The output shaft of the reciprocating motor is fixedly connected to the top surface of the threaded tube through the inside of the U-shaped frame, thereby enabling the threaded tube to rotate easily and the U-shaped frame to move up and down.
[0008] This utility model provides an easily adjustable surface roughening device for precast composite slabs. It features the following:
[0009] Beneficial effects:
[0010] 1. The adjustable surface roughening device for precast composite slabs allows the roughening plates to be rotated by a rotary motor, enabling the brush plates to rotate and roughen the surface of the composite slab with poured concrete. This facilitates the cleaning of the concrete adhered to the surface of the roughening plates by a scraper.
[0011] 2. The adjustable surface roughening device for precast composite slabs allows the movable plate to move out through the cooperation between the movable plate and the scraper, facilitating the cleaning of the scraper on the movable plate. Attached Figure Description

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0018] Example 1
[0019] Please see Figure 1-4This utility model provides an easily adjustable surface roughening device for precast composite slabs, including a U-shaped frame 1 and scrapers 9. A rotating rod 4 is rotatably connected inside the U-shaped frame 1. A rotary motor 5 is fixedly installed on the right side wall of the U-shaped frame 1. The output shaft of the rotary motor 5 is fixedly connected to the end of the rotating rod 4 through the inside of the side wall of the U-shaped frame 1. Roughening plates 3 are fixedly installed at equal intervals on the rod wall of the rotating rod 4. A movable plate 2 is slidably connected inside the U-shaped frame 1. Multiple scrapers 9 are provided and fixedly installed at equal intervals on the movable plate. On the bottom surface of 2, adjacent scrapers 9 are respectively set on both sides of the roughening sheet 3 and are respectively attached to the side wall of the roughening sheet 3. When roughening the precast composite slab, the composite slab is under the U-shaped frame 1, so that the roughening sheet 3 roughens the surface of the composite slab. Turn on the rotary motor 5, so that the rotating rod 4 drives the roughening sheet 3 to rotate, thereby enabling the roughening sheet 3 to rotate between the two scrapers 9, and the surface of the roughening sheet 3 can be cleaned by the scrapers 9, which can prevent the edges of the roughening sheet from sticking to the concrete.
[0020] Example 2
[0021] In this embodiment, as Figure 1-4 As shown, the two side walls inside the U-shaped frame 1 are provided with limiting grooves 11. The two ends of the movable plate 2 are slidably connected to the inside of the limiting grooves 11. The two side walls of the movable plate 2 are in contact with the side walls inside the limiting grooves 11. The movable plate 2 is internally threaded with a fixing bolt 12. The length of the fixing bolt 12 is greater than the width of the movable plate 2. The fixing bolt 12 is connected to the inside of the side wall of the limiting groove 11 through the internal thread of the movable plate 2. When disassembling the scraper 9, rotating the fixing bolt 12 causes the fixing bolt 12 to disengage from the inside of the side wall of the U-shaped frame 1, which loosens the position of the movable plate 2, thereby making it easy to disassemble the movable plate 2 and facilitate cleaning of the scraper 9.
[0022] Example 3
[0023] In this embodiment, as Figure 1-4 As shown, limit plates 6 are symmetrically arranged below the U-shaped frame 1. The limit plates 6 are slidably connected to the inside of the two side walls of the U-shaped frame 1. Support seats 8 are fixedly installed at the bottom of the limit plates 6. Screws 7 are fixedly connected to the top surface of the support seats 8. Threaded tubes 13 are rotatably connected to the inside of the two side walls of the U-shaped frame 1. The screws 7 are threadedly connected to the inside of the threaded tubes 13. Reciprocating motors 10 are symmetrically fixedly installed on the top surface of the U-shaped frame 1. The output shafts of the reciprocating motors 10 are fixedly connected to the top surface of the threaded tubes 13 through the inside of the U-shaped frame 1. According to the height of the surface of the stacked plate, the reciprocating motors 10 are turned on to rotate the threaded tubes 13, thereby making it easy to move the position of the U-shaped frame 1 up and down and adjust the position of the roughening sheet 3.
[0024] It should be noted that in this embodiment, when using an easily adjustable prefabricated composite slab surface roughening device, such as... Figure 1-4 As shown, according to the height of the surface of the precast composite slab, the reciprocating motor 10 is turned on, causing the threaded tube 13 to rotate, thereby facilitating the up-and-down movement of the U-shaped frame 1 and adjusting the position of the roughening plate 3. When roughening the precast composite slab, the composite slab is located below the U-shaped frame 1, allowing the roughening plate 3 to roughen the surface of the composite slab. The rotary motor 5 is turned on, causing the rotating rod 4 to drive the roughening plate 3 to rotate, thereby allowing the roughening plate 3 to rotate between the two scrapers 9 and clean the surface of the roughening plate 3 through the scrapers 9, preventing the edges of the roughening plate from sticking to concrete. When disassembling the scrapers 9, the fixing bolt 12 is rotated, causing the fixing bolt 12 to disengage from the side wall of the U-shaped frame 1, thereby loosening the position of the moving plate 2, making it easy to disassemble the moving plate 2 and facilitate cleaning of the scrapers 9.
