Description

Technical Field

[0001] The invention relates to the technical field of casting of concrete slabs, and in particular to a casting and forming device and a forming method of an assembled concrete slab. Background Art

[0002] Concrete slab is a green and environmentally friendly building material that uses cement, lime, silica sand and other siliceous materials as the main raw materials, and then adds different amounts of anti-corrosion treated steel mesh according to structural requirements.

[0003] According to the Chinese patent application with application number 201710770500.7, a method for preparing an autoclaved aerated concrete block includes the following steps: mixing pretreated zeolite powder, coal gangue, basalt powder, and light calcium carbonate evenly, adding urea, sodium lignin sulfonate, and water to mix evenly, adding microcrystalline paraffin and stirring, adding melamine resin and stirring, adding pyrophosphoric acid and mixing evenly, statically pressing and molding, and then autoclaving to obtain an autoclaved aerated concrete block. The pretreated zeolite powder is prepared by the following process.

[0004] When preparing concrete slabs, concrete slurry needs to be poured into the molding mold, and then the concrete slurry is pressed with a pressing plate. After the concrete slurry is solidified and formed, the pressing plate is removed to complete the production of the concrete slab. However, in actual operation, after the concrete slurry is poured into the molding mold, it is necessary to use a leveling device to level the concrete poured in the molding mold, which can ensure that each position in the molding mold is filled with concrete slurry and effectively prevent the appearance of surface potholes on the formed concrete slab.

The ends of the two L-shaped connecting plates 8 away from the vertical plates 7 are inserted into the inner cavity of the slide grooves, wherein the slide grooves can limit the trajectory of the L-shaped connecting plates 8 sliding up and down, which is beneficial to improve the stability of the two L-shaped connecting plates 8 sliding up and down, and at the same time push the two L-shaped connecting plates 8 to move away from the forming mold 2 until the flattening rollers 13 and the flattening blocks 5 are completely removed from the forming mold 2, and then pull the two L-shaped connecting plates 8 to move along the horizontal direction of the bottom plate 1, which is beneficial to the forming mold 2 to detach from the fixing parts and separate from the bottom of the bottom plate 1.

[0030] A linkage groove connected to the slide groove is provided on the side of one of the slide plates 4 away from the forming mold 2, wherein a brake block 20 is fixedly installed on one side of the L-shaped connecting plate 8 close to the supporting linkage groove, the brake block 20 passes through the linkage groove and extends to the outside of the slide plate 4, and a threaded hole is provided on the top of the brake block 20, a driving threaded rod 6 is installed in the inner cavity of the threaded hole through threaded cooperation, wherein a reciprocating motor for driving the threaded rod 6 to rotate is fixedly installed on the outer wall of the slide plate 4 close to the linkage groove, the reciprocating motor is started to rotate the driving threaded rod 6, and with the cooperation of the threaded hole, the distance moved by the brake block 20 in the vertical direction with the base plate 1 can be controlled, and the brake block 20 can be positioned after moving, which is beneficial to accurately control the distance between the bottom of the leveling roller 13 and the top of the concrete slurry, and is beneficial to the leveling block 5 to continuously level the concrete slurry.

[0031] A transmission threaded rod 19 is rotatably installed on one side of the inner cavity of the two sliding grooves 3, and a threaded groove compatible with the transmission threaded rod 19 is opened on one side of the two sliders 17. The free end of the transmission threaded rod 19 passes through the threaded groove and is rotatably connected to the other side of the inner cavity of the sliding groove 3. The two transmission threaded rods 19 are rotated at the same time, and the two sliders 17 are moved synchronously along the trajectory opened by the sliding groove 3 with the cooperation of the threaded groove. At the same time, the rotation direction of the transmission threaded rod 19 is changed, which is beneficial to controlling the moving direction of the two sliders 17 and the distance between the flattening roller 13 and the forming mold 2.

[0032] Furthermore, the sliding groove 3 can limit the sliding track of the slider 17, preventing the slider 17 from rotating together with the transmission threaded rod 19, thereby improving the stability of the slider 17 moving back and forth.

[0033] One end of the base plate 1 is symmetrically provided with through holes connected to the inner cavity of the sliding groove 3.

[0034] Example 2, please refer to Figure 1-5 , further improvements made on the basis of Example 1: A baffle plate 9 is arranged between the two vertical plates 7. The baffle plate 9 is located directly above the flattening roller 13, and the two ends of the baffle plate 9 are fixedly connected to the adjacent sides of the two vertical plates 7 respectively. When the flattening block 5 beats the concrete slurry, part of the concrete slurry is easy to adhere to the outer wall of the flattening block 5. As the flattening roller 13 rotates, the concrete slurry adhered to the outer wall is thrown to the inner wall of the baffle plate 9 under the action of centrifugal force, thereby blocking the splashing concrete slurry, and effectively reducing the adverse effects on the flattening of the concrete slurry.

[0035] A transmission rod 14 is provided directly above the baffle plate 9, and both ends of the transmission rod 14 are rotatably connected to the adjacent sides of the two vertical plates 7 respectively, and the outer wall of the transmission rod 14 is fixedly installed with a plurality of knocking blocks 15 for knocking the top of the baffle plate 9 along its own axial direction, wherein the knocking block 15 rotates eccentrically with the rotation of the transmission rod 14. When the knocking block 15 rotates eccentrically with the transmission rod 14, the end farther from the transmission rod 14 contacts the top of the baffle plate 9, thereby knocking the outer wall of the baffle plate 9 to make the baffle plate 9 vibrate. At this time, the concrete slurry attached to the inner wall of the baffle plate 9 quickly falls into the interior of the forming mold 2 and mixes with the concrete slurry again, preventing a large amount of concrete slurry attached to the inner wall of the baffle plate 9 from solidifying on its own inner wall and causing an adverse effect on the normal rotation of the flattening roller 13, and at the same time is conducive to the recycling of the concrete slurry.

[0036] The outer wall of the transmission rod 14 is fixedly sleeved with a driving gear 10, which is located between the two transmission gears 11, and the driving gear 10 and the transmission chain are engaged with each other. When the two transmission gears 11 rotate, the transmission chain rotates accordingly. At this time, the transmission chain transmits power to the driving gear 10, allowing the driving gear 10 to rotate, and the driving gear 10 transmits power to the transmission rod 14, which is beneficial to improving the convenience of rotating the transmission rod 14.

[0037] Mounting rings are symmetrically installed on the same side of the two vertical plates 7, and a concrete feed pipe 16 is arranged between the two mounting rings. Both ends of the concrete feed pipe 16 are inserted into the inner cavities of the two mounting rings. The two mounting rings are conducive to the installation and positioning of the concrete feed pipe 16, so that the concrete feed pipe 16 can move with the L-shaped connecting plate 8. The outer wall of the concrete feed pipe 16 is connected to a concrete slurry pouring pipe. The concrete slurry pouring pipe transfers the concrete slurry to the interior of the concrete feed pipe 16, and pours the concrete slurry into the interior of the forming mold 2 through the movement of the concrete feed pipe 16, which is conducive to the uniformity of the concrete slurry pouring in the forming mold 2.

[0038] A U-shaped reinforcing rib plate 12 is provided on the top of the material baffle plate 9, and one end of the U-shaped reinforcing rib plate 12 is fixedly connected to the tops of the two L-shaped connecting plates 8, wherein the U-shaped reinforcing rib plate 12 can connect the tops of the two L-shaped connecting plates 8 while improving the strength between the two L-shaped connecting plates 8.
