Description

Technical Field

[0001] This invention relates to the field of building construction technology, and in particular to a plastering process and plastering device for building engineering. Background Technology

[0002] Exterior wall painting is a crucial step in building construction. Traditional wall painting is mainly done manually, resulting in low efficiency and high labor intensity. Furthermore, in existing processes, cement slurry is mostly applied to the wall surface using plastering tools and then compacted under pressure to achieve adhesion. For example, patent application number 202110693306.X discloses a construction device for building exterior walls.

[0003] However, the modification has the following disadvantages when in use: because the plastering mechanism of the device needs to move laterally during use, the horizontal sliding component, which serves as the horizontal travel guide of the plastering mechanism, must be installed on the wall to support the plastering mechanism. As a result, when the device is used outdoors, expansion bolts need to be drilled into the wall to fix the horizontal sliding component. This not only makes it more troublesome to change the operating position and carry out plastering work in other areas, but also the excessive drilling of holes in the wall will damage the waterproof performance of the wall.

[0050] 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.

[0051] Example 1: A plastering device for building construction, such as Figure 1 and Figure 2 As shown, the system includes a side support frame 1 and a movable plastering mechanism. The side support frame 1 includes a bottom horizontal support frame, a top horizontal support frame, and a vertical support rod 103. The top horizontal support frame is located directly above the bottom horizontal support frame. Both the top and bottom horizontal support frames include two first horizontal beams 101 that are spaced apart from each other and extend in the front-back direction. The front and rear ends of each first horizontal beam 101 are fixedly connected to second horizontal beams 102 that extend in the left-right direction. The two second horizontal beams 102 are fixedly connected to each other by the vertical support rod 103.

[0052] A push rod 2 extending backward is fixedly installed on the rear vertical support rod 103.

[0053] The bottom of the bottom horizontal support frame is equipped with traveling wheels 5, and the top of the top horizontal support frame is fixedly equipped with a winch 20.

[0054] The rear side of the side support frame 1 is detachably fixed with two first connecting parts 6 spaced apart on the left and right by bolts. The rear side of the first connecting parts 6 is connected with a slide rail by bolts. The slide rail extends in the vertical direction. The bottom of the slide rail is higher than the bottom of the traveling wheel 5, and the top of the slide rail is higher than the top of the side support frame 1. The front part of the slide rail is provided with a slider 13 that can move up and down.

[0055] In order to adapt the sliding rail to the construction needs of walls of different heights, such as Figure 1 , Figure 2 and Figure 3 As shown, in this embodiment, the slide rail includes multiple slide rail sections 7 that can be connected vertically. A crossbar 12 is detachably and rotatably connected between the upper ends of the two uppermost slide rail sections 7 on opposite sides, and the crossbar 12 extends in the left and right direction.

[0056] Specifically, such as Figure 1 and Figure 3 As shown, the upper ends of the two uppermost slide rail sections 7 on the left and right are fixedly provided with rotating connecting parts. The rotating connecting parts include second connecting plates 9. The second connecting plates 9 are fixedly provided on the opposite side of the two slide rails. The side of the second connecting plate 9 away from the slide rail is fixedly provided with an arc-shaped support plate 10 with an upper opening. The arc of the arc-shaped support plate 10 is greater than 180 degrees. The arc-shaped support plate 10 is provided with a first bearing 11 that can slide left and right. The end of the crossbar 12 is inserted into the two first bearings 11 on the left and right.

[0057] There is a gap between the end of the crossbar 12 and the second connecting plate 9, and the width of the gap between the end of the crossbar 12 and the second connecting plate 9 is greater than the left and right thickness of the first bearing 11, so that the crossbar 12 can be quickly disassembled and replaced.

[0058] The crossbar 12 is rotatably connected to the slide rail via a rotating connector, so that the crossbar 12 can rotate smoothly when subjected to the friction force of the sling 19, thereby reducing the friction force.

[0059] The slide rail section 7 is provided with two first internal threaded holes 701 spaced apart on the outer side away from the crossbar 12. The slide rail sections 7 after being joined together are connected by a first connecting plate 8. Two connecting screws spaced apart on the first connecting plate 8 are rotatably inserted. One end of the two connecting screws is inserted into the first internal threaded holes 701 of the two slide rail sections 7 respectively, and the connecting screws are threadedly connected to the first internal threaded holes 701.

[0060] The upper and lower ends of the slide rail section 7 are provided with multiple rectangularly distributed calibration holes 702. Calibration rods are inserted into the calibration holes 702 of two adjacent slide rail sections 7. The lower end of the calibration rod is inserted into the calibration hole 702 of the lower slide rail section 7, and the upper end of the calibration rod is inserted into the calibration hole 702 of the upper slide rail section 7.

[0061] The calibration rod serves two purposes: first, it facilitates quick calibration and connection of the two slide rail sections 7; second, it improves the shear resistance at the connection point of the two slide rail sections 7.

[0062] The rear side of the slider 13 is detachably fixed with a second connecting piece 14 by bolts, and the rear side of the second connecting piece 14 is detachably fixedly connected to the movable plastering mechanism.

[0063] In this embodiment, both the first connector 8 and the second connector 14 adopt a frame plate structure to facilitate the installation of bolts.

[0064] The mobile plastering mechanism includes a housing 15, which is a square box structure. The housing 15 contains a partition structure, such as... Figure 4 , Figure 5 and Figure 6 As shown, the partition structure is provided with a rear baffle 22, an inclined bottom plate 23 and a flat bottom plate 23 in sequence from back to front. The rear baffle 22 is set vertically, the inclined bottom plate 23 is set at an angle with the front higher than the back, and the flat bottom plate 23 is set horizontally.

[0065] The upper end of the rear baffle 22 is fixedly connected to the top plate of the housing 15, the lower end of the rear baffle 22 is fixedly connected to the front end of the inclined bottom plate 23, and the rear end of the inclined bottom plate 23 is fixedly connected to the front end of the flat bottom plate 23.

[0066] In order to quickly adjust the gap between the shell 15 and the wall surface during the plastering process, and to prevent mortar from overflowing from the left and right sides of the shell 15, such as Figure 5 and Figure 6 As shown, in this embodiment, there are gaps between the left and right sides of the rear baffle 22, the inclined bottom plate 23, and the inner walls of the left and right sides of the housing 15.

[0067] The left and right sides of the rear baffle 22 and the inclined bottom plate 23 are aligned front and back, and the left and right sides of the flat bottom plate 23 extend to the outside of the left and right ends of the inclined bottom plate 23.

[0068] The rear baffle 22 and the inclined bottom plate 23 are fixedly provided with first side plates 25 on the left and right sides, and the flat bottom plate 23 is fixedly provided with second side plates 26 on the left and right sides. The rear end of the first side plate 25 and the front end of the second side plate 26 are connected by a third side plate extending in the left and right direction. The tops of the first side plate 25, the second side plate 26 and the third side plate are all fixedly connected to the top plate of the housing 15.

[0069] A limiting baffle 28 capable of moving back and forth is provided in the gap between the second side plate 26 and the housing 15. The limiting baffle 28 has an L-shaped plate structure, and the thickness of the limiting baffle 28 is equal to the width of the gap between the second side plate 26 and the housing 15. The rear part of the limiting baffle 28 is connected to the front end of the electrically controlled telescopic rod 27, and the rear end of the electrically controlled telescopic rod 27 is fixedly connected to the rear side plate of the housing 15. In this embodiment, the electrically controlled telescopic rod 27 is an electric push rod (in other embodiments, a hydraulic cylinder, pneumatic cylinder, or other telescopic cylinder structure can also be used).

[0070] The front end of the limiting baffle 28 can extend to the front of the housing 15 under the push of the electrically controlled telescopic rod 27, and the front end of the limiting baffle 28 can enter the gap between the second side plate 26 and the housing 15 under the pull of the electrically controlled telescopic rod 27.

[0071] like Figure 4 , Figure 5 ,and Figure 6 As shown, the housing 15 is provided with a plurality of first smoothing mechanisms arranged at left and right intervals, and the first smoothing mechanisms are located below the partition structure.

[0072] The first smoothing mechanism includes a first rotating shaft 31 extending in the front-rear direction. The rear end of the first rotating shaft 31 is rotatably connected to the rear side plate of the housing 15. A first gear 33 is provided on the first rotating shaft 31. A vertically arranged first smoothing plate 32 is fixedly provided at the front end of the first rotating shaft 31. The first smoothing plate 32 is a circular plate structure.

[0073] The front panel of the housing 15 is provided with a plurality of first circular grooves spaced apart on the left and right. Each first circular groove corresponds to a first smoothing mechanism. The center of the first circular groove is provided with a first shaft hole that is open from front to back. The front end of the first rotating shaft 31 rotates through the first shaft hole. The first smoothing plate 32 is rotatably disposed in the first circular groove. The front side of the first smoothing plate 32 is flush with the front panel of the housing 15.

[0074] The housing 15 is provided with a plurality of second smoothing mechanisms arranged at left and right intervals, and the second smoothing mechanisms are located below the first smoothing mechanism.

[0075] The second smoothing mechanism includes a second rotating shaft 34 extending in the front-rear direction. The rear end of the second rotating shaft 34 is rotatably connected to the rear side plate of the housing 15. A second gear 36 is provided on the second rotating shaft 34. The second smoothing plate 35 is a circular plate structure.

[0076] The front panel of the housing 15 is provided with a plurality of second circular grooves spaced apart from left to right. Each second circular groove corresponds to a second smoothing mechanism. The center of the second circular groove is provided with a first shaft hole that is open from front to back. The front end of the second rotating shaft 34 rotates through the first shaft hole. The front end of the second rotating shaft 34 is fixedly provided with a vertically arranged second smoothing plate 35. The second smoothing plate 35 is rotatably disposed in the second circular groove. The front side of the second smoothing plate 35 is flush with the front panel of the housing 15.

[0077] A drive motor 37 is fixedly installed on the rear side of the housing 15. The output shaft of the drive motor 37 rotates through the rear side plate of the housing 15. A drive gear 37 is fixedly installed on the output shaft of the drive motor 37. There is a gap between the rear end of the drive motor 37 and the crossbar 12. A transmission chain 39 that meshes with each other is wound around the drive gear 37, the first gear 33 and the second gear 36.

[0078] likeFigure 7 As shown, the second trowel plate 35 and the first trowel plate 32 are installed in a staggered manner in the left and right direction so that the second trowel plate 35 can smooth the gap between adjacent first trowel plates 32.

[0079] By employing a first smoothing mechanism and a second smoothing mechanism in conjunction with the front panel of the housing 15, the smoothness of the plaster surface is significantly improved during the plastering process.

[0080] The housing 15 has a buffer chamber 29 separated by a partition structure. A mortar outlet is provided on the front panel of the housing 15, and the mortar outlet is connected to the buffer chamber 29.

[0081] The top of the housing 15 is provided with a grouting port 16. The bottom of the grouting port 16 is connected to the buffer chamber 29. The top of the grouting port 16 is connected to one end of the grouting pipe 17. The grouting pipe 17 is a flexible pipe that can be bent. The other end of the grouting pipe 17 is connected to the grout pumping mechanism.

[0082] Specifically, in this embodiment, such as Figure 1 As shown, the mortar pumping mechanism includes a mortar tank 3 and a concrete pump 4; the mortar tank 3 is located on the top of the bottom horizontal support frame, the concrete pump 4 is fixedly located on the top of the top horizontal support frame, the inlet of the concrete pump 4 is connected to one end of the grouting pipe 21, the other end of the grouting pipe 21 extends downward into the mortar tank 3, and the outlet of the concrete pump 4 is connected to the other end of the grouting pipe 17.

[0083] The mortar box 3 is used to store mortar so that when it is used, the grouting pipe 17 does not need to be set too long and connected to the concrete pump at the mortar mixing tank. This is to prevent the grouting pipe 17 from getting tangled when the side support 1 moves to adjust the plastering position, which would affect the mortar discharge speed.

[0084] A lifting ring 18 is fixedly provided on the rear side of the housing 15. The lifting ring 18 is detachably and fixedly connected to one end of the sling 19, and the other end of the sling 19 passes around the crossbar 12 and is connected to the winch 20.

[0085] A plastering process for building construction includes the following steps: S1. First, according to the required wall height, install a slide rail of appropriate height on the side frame 1. Then, install the horizontal bar 12 and the movable plastering mechanism on the slide rail. Connect the movable plastering mechanism to the winch 20 through the sling 19. The sling 19 passes around the horizontal bar 12, so that the horizontal bar 12 is used for the steering and support of the sling.

[0086] S2. Remove the burrs from the wall surface to be worked on, then wet the wall surface and push the device to the side of the wall to be worked on. The initial position is selected at the corner between the wall and the other side wall.

[0087] If the construction wall is an interior wall, the left or right side of the housing 15 is pressed against the other side of the wall, and the electric telescopic rod 27 away from the corner is extended to push out the limiting baffle 28 so that the vertical distance between the front end of the limiting baffle 28 and the front panel of the housing 15 is equal to the design thickness of the ash layer.

[0088] If the wall surface to be constructed is an outdoor wall surface, align the left or right side of the shell 15 with the other side of the wall surface, connect the movable plastering mechanism to the grout pumping mechanism through the grouting pipe 17, control the two electrically controlled telescopic rods 27 to extend simultaneously, push out the limiting baffle 28, so that the vertical distance between the front end of the limiting baffle 28 and the front panel of the shell 15 is equal to the design thickness of the mortar layer.

[0089] S3. By moving the side support 1, the front end of the limiting baffle 28 is pressed against the construction wall, the position adjustment of the shell 15 is quickly completed, and the bottom of the shell 15 is pressed against the ground.

[0090] S4. Start the mortar pumping mechanism to inject mortar into the buffer chamber 29 inside the housing 15. At the same time, start the winch 12 to slowly pull the housing 15 up. The mortar in the buffer chamber 29 flows out from the mortar outlet on the front panel of the housing 15 and is smoothed by the continuously rising front panel of the housing 15.

[0091] S5. After the plastering of the area is completed, stop the mortar pumping mechanism, move the side support 1 to move the mortar outlet to the second construction position, release the hoisting cable 19, so that the bottom of the shell 15 is back against the ground, and repeat step S4.

[0092] S6. Repeat steps S4 to S5 until the plastering of the wall surface is completed.

[0093] Example 2: A plastering device for building construction.
