Description

Technical Field

[0001] This application relates to the field of building construction, and more specifically, to a device for casting and molding self-compacting concrete for decorative flooring. Background Technology

[0002] Self-compacting concrete, due to its high fluidity and self-compacting properties, can fill every corner of the formwork under its own weight without vibration, and is increasingly widely used in modern construction projects. For example, in decorative flooring projects, pre-formed self-compacting concrete is required. However, in actual construction, traditional pouring methods still have some problems. First, when pouring self-compacting concrete directly from a height, segregation is very likely to occur due to the difference in density and fluidity between aggregates and slurry, affecting the homogeneity and final strength of the concrete. Second, if the pouring points are too concentrated, the concrete will spread in a "springing" manner within the formwork, easily trapping air and forming bubbles. To address this, we have proposed a self-compacting concrete pouring and forming device for decorative flooring. Utility Model Content

[0003] To overcome the above shortcomings, this application provides a self-compacting concrete casting and molding device for decorative flooring, which aims to improve the problem of segregation that easily occurs during the material discharge process of existing self-compacting concrete casting and molding devices.

[0004] This application provides a self-compacting concrete casting and molding device for decorative flooring, including a mobile vehicle body. A conveying assembly for conveying self-compacting concrete is installed on the top of the mobile vehicle body. A hose is connected to the outlet end of the conveying assembly, an anti-segregation conduit is connected to the outlet end of the hose, and a buffer diffusion nozzle is connected to the outlet end of the anti-segregation conduit. A support assembly is also installed on the outer wall of the mobile vehicle body, and the support assembly clamps the buffer diffusion nozzle.

[0005] In one specific implementation, the conveying assembly includes a self-compacting concrete storage cylinder mounted on the mobile vehicle body, a conveying pump connected to the side wall of the self-compacting concrete storage cylinder, and a hose connected to the conveying pump.

[0006] In one specific implementation, a plurality of grid plates are fixedly installed on the inner wall of the anti-segregation conduit, and the plurality of grid plates are arranged at equal intervals.

[0007] In one specific implementation, several of the grid plates are inclined, and the inclination directions of two adjacent grid plates are opposite.

[0008] In one specific implementation, the buffer diffusion nozzle includes a U-shaped plate, the anti-segregation conduit is connected to the U-shaped plate, an adjustment component is fixedly installed on the outer wall of the U-shaped plate, and two adjustment blocks are installed on the adjustment component, both of which are slidably disposed inside the U-shaped plate.

[0009] In one specific implementation, a discharge plate is fixedly connected to the bottom of the U-shaped plate, and the discharge plate has several discharge holes. The bottoms of the two adjusting blocks are slidably in contact with the top of the discharge plate.

[0010] In one specific implementation, the adjustment assembly includes a drive rod and a double-ended screw. Both the drive rod and the double-ended screw are mounted on the outer wall of the U-shaped plate. The drive rod is connected to the double-ended screw in a transmission connection. Two connecting pipes are threaded onto the double-ended screw. Connecting rods are fixedly connected to the outer walls of the two connecting pipes. The two connecting rods are respectively fixedly connected to the two adjustment blocks.

[0011] In one specific implementation, two sealing tubes are fixedly installed on the outer wall of the U-shaped plate, and one end of each of the two connecting tubes is slidably disposed inside the two sealing tubes. The double-headed screw is rotatably disposed through the side wall of the two sealing tubes.

[0012] The beneficial effects of this application are as follows: By installing a conveying assembly on a mobile vehicle body, with the outlet end of the conveying assembly connected to a flexible hose, and the outlet end of the flexible hose connected to an anti-segregation conduit, the conveying assembly delivers self-compacting concrete through the hose to the anti-segregation conduit. Several staggered grid plates are installed on the inner wall of the anti-segregation conduit, effectively breaking up the falling concrete as it passes through, thus disrupting its segregation tendency and ensuring the uniformity of the concrete components. By connecting a buffer diffusion nozzle to the outlet of the anti-segregation conduit, the concrete, after being slowed down by the conduit, enters the buffer diffusion head with a larger cross-sectional area, further reducing the flow velocity and buffering the kinetic energy. Finally, the concrete is smoothly and evenly spread onto the casting surface in the form of multiple "small streams" through multiple discharge holes at the bottom, avoiding concentrated impact at a single point and effectively reducing the generation of air bubbles.

Detailed Implementation

[0016] The technical solutions in the embodiments of this application will now be described with reference to the accompanying drawings.

[0017] Please see Figure 1-5 This application provides a self-compacting concrete casting and molding device for decorative flooring, including a mobile vehicle body 10. A conveying assembly 20 for conveying self-compacting concrete is installed on the top of the mobile vehicle body 10. A hose 30 is connected to the outlet end of the conveying assembly 20, and an anti-segregation conduit 40 is connected to the outlet end of the hose 30. Specifically, the position of the anti-segregation conduit 40 can be controlled by holding it by hand. Furthermore, a buffer diffusion nozzle 50 is connected to the outlet end of the anti-segregation conduit 40, thereby controlling the position of the buffer diffusion nozzle 50 by controlling the anti-segregation conduit 40, so as to align the buffer diffusion nozzle 50 with the concrete molding mold and allow the concrete to enter the molding mold to complete the concrete casting and molding. A support assembly 60 is also installed on the outer wall of the mobile vehicle body 10. The support assembly 60 clamps the buffer diffusion nozzle 50. The support assembly 60 includes a fixing rod, one end of which is connected to an elastic sleeve. The elastic sleeve can clamp the anti-segregation conduit 40. Furthermore, a transparent window can be provided on the anti-segregation conduit 40 to facilitate observation of the internal situation.

[0018] See Figure 1The conveying assembly 20 includes a self-compacting concrete storage cylinder 210, which is mounted on the mobile vehicle body 10. A conveying pump 220 is connected to the side wall of the self-compacting concrete storage cylinder 210. A hose 30 is connected to the conveying pump 220. The self-compacting concrete storage cylinder 210 is used to store self-compacting concrete, and the conveying pump 220 conveys the concrete into the hose 30.

[0019] See Figure 4 Several grid plates 410 are fixedly installed on the inner wall of the anti-segregation conduit 40. Specifically, the grid plates 410 allow concrete to pass through. The grid plates 410 are arranged at equal intervals and are all inclined. The inclination directions of two adjacent grid plates 410 are opposite. When the concrete flows through, it will be cut, dispersed and mixed multiple times by these interlaced grid plates 410, thereby effectively inhibiting segregation.

[0020] See Figure 3 The buffer diffusion nozzle 50 includes a U-shaped plate 510 and an anti-segregation conduit 40 connected to the U-shaped plate 510. Specifically, the top of the U-shaped plate 510 has a through-hole, and the bottom of the anti-segregation conduit 40 is tapered and connected to the through-hole. An adjustment component 520 is fixedly installed on the outer wall of the U-shaped plate 510. Two adjustment blocks 530 are installed on the adjustment component 520. Both adjustment blocks 530 are slidably disposed inside the U-shaped plate 510. By adjusting the distance between the two adjustment blocks 530, the size of the outlet of the U-shaped plate 510 can be adjusted to adapt to different sizes of templates or narrow, densely reinforced pouring areas.

[0021] See Figure 3A discharge plate 540 is fixedly connected to the bottom of the U-shaped plate 510. The discharge plate 540 has several discharge holes 550. The bottoms of two adjusting blocks 530 are slidably in contact with the top of the discharge plate 540. Concrete is discharged from the discharge holes 550. The adjusting assembly 520 includes a drive rod 5210 and a double-ended screw 5220. Both the drive rod 5210 and the double-ended screw 5220 are installed on the outer wall of the U-shaped plate 510. The drive rod 5210 and the double-ended screw 5220 are connected in a transmission connection. Specifically, a transmission box is fixedly installed on the outer wall of the U-shaped plate 510. One end of the drive rod 5210 rotatably passes through the side wall of the transmission box, while the cylindrical part of the double-ended screw 5220 rotatably passes through the transmission box. A first bevel gear is installed at one end of the moving rod 5210, while a second bevel gear is fitted on the double-ended screw 5220. The first bevel gear and the second bevel gear are meshed together. Both the first bevel gear and the second bevel gear are located inside the transmission box. Two connecting pipes 5230 are threaded onto the double-ended screw 5220. Connecting rods 5240 are fixedly connected to the outer walls of the two connecting pipes 5230. The two connecting rods 5240 are fixedly connected to the two adjusting blocks 530 respectively. By rotating the driving rod 5210, the driving rod 5210 drives the double-ended screw 5220 to rotate, thereby causing the two connecting pipes 5230 to move. The two connecting pipes 5230 drive the two connecting rods 5240 to move, so as to adjust the distance between the two adjusting blocks 530.

[0022] See Figure 5 Two sealing tubes 560 are fixedly installed on the outer wall of the U-shaped plate 510. Specifically, each of the two sealing tubes 560 has a mounting block fixedly connected to its outer wall. Both mounting blocks are fixedly connected to the outer wall of the U-shaped plate 510. One end of each of the two connecting tubes 5230 is slidably installed inside the two sealing tubes 560. The double-headed screw 5220 is rotatably installed through the side wall of the two sealing tubes 560.

[0023] When this self-compacting concrete casting and molding device for decorative flooring is in operation: the moving vehicle 10 moves the conveying component 20 to the molding mold, then moves the anti-segregation conduit 40 to move the buffer diffusion nozzle 50 to the molding mold. The self-compacting concrete is conveyed through the conveying component 20 into the hose 30, and then enters the anti-segregation conduit 40 through the hose 30. The self-compacting concrete passes through the grating plate 410, is broken up by the grating plate 410, and enters the U-shaped plate 510. Finally, the concrete is discharged into the molding mold through several discharge holes 550 for molding and is used for floor decoration. When the mold opening is too small, the drive rod 5210 is rotated, which drives the double-headed screw 5220 to rotate. The double-headed screw 5220 drives the two connecting pipes 5230 to move. The two connecting pipes 5230 drive the two adjusting blocks 530 to move towards each other through the two connecting rods 5240, thereby narrowing the outlet of the U-shaped plate 510 and allowing the concrete to be accurately discharged into the molding mold.
