Technical Field
[0001] This application relates to the field of cast-in-place floor leveling technology, and in particular to a construction device and method for leveling cast-in-place floor slabs. Background Technology
[0002] With the development of urbanization, buildings are closely related to our lives. In order to provide high-quality buildings faster and better, prefabricated construction is adopted in the construction of building floors. In the construction process, composite slabs are spliced together and then concrete is poured on the composite slabs. Then the concrete is leveled. For example, the patent application number CN202110039399.4 discloses a prefabricated construction floor leveling device. In the process of leveling the floor, the vibration device has no supporting structure on the lower side. During the vibration leveling process, uneven local laying of concrete will cause a large difference in the height of the leveled floor, resulting in an uneven floor. Summary of the Invention
[0003] The purpose of this application is to provide a construction equipment and method for leveling cast-in-place floor slabs, in order to solve the technical problem that "when the vibration device has no supporting structure on the underside, uneven concrete distribution will cause a large difference in the height of the leveled floor, resulting in an uneven floor surface" during the vibration leveling process.
[0004] Firstly, the cast-in-place floor slab leveling construction equipment provided in this application adopts the following technical solution:
[0005] A leveling construction device for cast-in-place floor slabs includes a limiting component for limiting the thickness of concrete, and a leveling mechanism placed on the limiting component. The leveling mechanism is used to vibrate and uniformly compact the concrete laid on the composite slab. The limiting component is installed between the composite slabs. The leveling mechanism includes a vibrating frame, a leveling bucket installed on one side of the vibrating frame for leveling the concrete, and a scraper plate installed on the side of the vibrating frame away from the leveling bucket. A first tilting component for controlling the tilting of the leveling bucket is installed inside the vibrating frame. A second tilting component for controlling the tilting of the scraper plate is installed inside the vibrating frame. A support bar is provided at the upper end of the limiting component. The support bar is parallel to the composite slab.
[0006] By adopting the above technical solution, a leveling bucket for leveling concrete is installed on the vibrating frame. During the movement of the leveling mechanism, the leveling bucket pushes the concrete that is piled up on the composite plate to the lower part of the concrete, so that the concrete is evenly spread on the composite plate.
[0007] The first flipping component controls the angle of the leveling bucket, keeping a certain distance between the leveling bucket and the upper side of the support bar, so that the leveled concrete maintains a uniform thickness and the vibrated concrete is evenly spread on the composite slab.
[0008] The second flipping component controls the flipping of the scraper plate, which then fits into the concrete to level the vibrated concrete.
[0009] Optionally, the limiting assembly includes a bonding plate installed on the lower side of the composite plate, multiple traction rods fixed on the bonding plate, a tension rod attached to the upper side of the composite plate, a traction nut installed on the traction rod, and a support bar installed on the fixed end of the traction rod; the traction rods are of equal length; the traction nut is used to adjust the distance between the tension rod and the bonding plate, so that the tension rod and the bonding plate generate a clamping force, locking the limiting assembly between adjacent composite plates.
[0010] By adopting the above technical solution, the undersides of the bonding plate and the composite plate are bonded together. The traction rod passes through the gap between the composite plates and then passes through the tension rod and is locked with the traction nut. This locks the limiting component between adjacent composite plates. Finally, the support strip is installed on the upper end of the traction rod. Since the traction rods are of the same length, the support strip is parallel to the bonding plate after it is installed at the top of the traction rod. Therefore, the support strip and the composite plate are also parallel structures. This allows the leveling mechanism to vibrate from the upper side of the limiting component. The vibrated concrete is flush with the upper side of the support strip, making the concrete poured on the upper side of the composite plate more evenly laid. After leveling, the unevenness of the floor surface caused by uneven concrete laying is reduced.
[0011] By attaching the bonding plate to the underside of the composite plate, attaching the tension rod to the upper side of the composite plate, and passing the traction rod through the gap between the composite plates, the composite plates are spliced together more neatly.
[0012] Optionally, the support bar has a snap-fit groove on the side where it connects with the traction rod to engage with the traction rod; an abutment rod is fixed on the support bar to abut against the tension rod; and an abutment groove is provided on the side where the tension rod connects with the abutment rod to allow the abutment rod to be inserted.
[0013] By adopting the above technical solution, the top of the traction rod is engaged in the engagement groove, and the abutment rod is engaged in the abutment groove, which facilitates the quick installation of the support bar.
[0014] The support bar and tension bar are supported at multiple points by the action of the traction bar and the abutment bar, making the structure more stable after the support bar is installed.
[0015] Optionally, the tension rod has connecting grooves at both ends for connecting to the concrete frame.
[0016] By adopting the above technical solution, the concrete clamp is snapped into the connecting grooves opened at both ends of the tension rod. The concrete clamp limits the horizontal displacement of the tension rod, making the tension rod, traction rod and support bar structure more stable, preventing the support bar from shifting significantly during vibration, and making the leveled floor surface more flat.
[0017] Optionally, a vibration generating assembly for generating vibration is installed on the vibrating frame; the vibration generating assembly includes a rotating shaft installed on the vibrating frame, a polarizing plate installed on the rotating shaft, and a driving component for driving the rotating shaft to rotate; a battery for powering the driving component, the first tilting component, and the second tilting component is installed on the vibrating frame.
[0018] By adopting the above technical solution, the drive component drives the rotating shaft to rotate at high speed. The polarizing plate installed on the rotating shaft generates inertia, causing the vibrating frame to vibrate, thus compacting the concrete and expelling the gas inside the concrete. Powered by a battery, the use of electrical wires is reduced.
[0019] Optionally, a vibration chamber is provided inside the vibrating frame; the rotating shaft and polarizing plate are installed inside the vibration chamber; the end of the vibration chamber is sealed by a sealing ring.
[0020] By adopting the above technical solution, the rotating shaft and polarizing plate work inside the vibration chamber. The end of the vibration chamber is sealed by a sealing ring, and the rotating shaft passes through the sealing ring and is driven by a driving component. This reduces the entry of concrete and the impact of sand and gravel on the rotating shaft and polarizing plate, making the leveling mechanism work more stably.
[0021] Optionally, traction lugs are installed on both sides of the vibratory frame.
[0022] By adopting the above technical solution, one end of the traction rope is fixed to the traction ear, and the leveling mechanism is pulled by the traction equipment, so that the vibrator moves horizontally on the upper side of the support bar.
[0023] Optionally, the bottom of the vibrating frame is a flat structure, while the sides are raised.
[0024] By adopting the above technical solution, the concrete is pressed under the vibrating frame during the movement of the vibrating frame. When the inclined part of the vibrating frame comes into contact with the concrete during the movement of the vibrating frame, the vibration causes the part that is higher than the upper side of the support bar to vibrate and then decrease in height. After being leveled by the leveling part, it is finally leveled by the scraper, so that the concrete surface after leveling is more flat.
[0025] Secondly, the construction method of the cast-in-place floor slab leveling equipment provided in this application adopts the following technical solution:
[0026] A construction method for a cast-in-place floor slab leveling construction device, comprising the following steps:
[0027] Step 1, Installation of Limiting Components: First, pass the traction rod through the gap between the laminated plates, then pass the tension rod through the traction rod, so that the laminated plate, traction rod and tension rod form an "T" structure, and the laminated plate is clamped between the tension rod and the laminated plate; then lock the traction nut to the traction rod, so that the tension rod and the laminated plate are clamped together; finally, attach the support bar to the upper end of the traction rod.
[0028] Step 2, cleaning the surface of the laminated board: First, use a broom to clean the sand off the surface of the laminated board, and then use a vacuum cleaner to clean the fine dust off the surface of the laminated board.
[0029] Step 3, Wetting the surface of the composite slab: Spray water onto the surface of the composite slab using a spraying device to ensure that the composite slab fully absorbs water;
[0030] Step 4: Pour concrete onto the upper side of the composite slab: Pour concrete onto the upper side of the composite slab using a concrete pump, with the thickness of the concrete extending one to three centimeters above the upper side of the support strip.
[0031] Step 5, Leveling mechanism adjustment: Place the vibratory frame on the concrete, with the lower side of the vibratory frame parallel to the limiting component;
[0032] Step 6, Adjusting the leveling bucket: Control the leveling bucket to rotate using the first tilting component, so that the lower side of the leveling bucket is one to three centimeters higher than the upper side of the support bar;
[0033] Step 7, adjust the scraper plate; control the scraper plate to fit against the upper side of the support bar using the second flipping component;
[0034] Step 8: Move the leveling mechanism; lock the traction rope to the traction ear, and use the traction device to pull the leveling mechanism to move and compact the concrete, while simultaneously pushing the concrete that is higher than the set height to a lower position; the scraper plate scrapes the vibrated concrete to level it during the movement.
[0035] By adopting the above technical solution
[0036] Before vibration, secure the limiting components to the composite slab and clean the dust from the upper side of the slab to minimize its impact on the adhesion between the slab and the concrete. Before laying the concrete, spray water onto the composite slab to allow it to fully absorb water before pouring the concrete. This prevents the slab from absorbing excessive water from the newly poured concrete, allowing it to react fully and reach the desired strength. Pour the concrete one to three centimeters above the top of the support strip, allowing it to drop to near flush with the top of the support strip after vibration, resulting in a smoother, more even concrete surface.
[0037] The leveling mechanism is placed on the concrete. After vibration, the vibrating frame moves downward, with its lower side parallel to the limiting component, so that the vibrating frame moves down and fits against the support bar.
[0038] The lower side of the leveling bucket should be one to three centimeters higher than the upper side of the support bar. Push the protruding part away so that after the vibrating frame is vibrated, the concrete drops to the same level as the upper side of the support bar, thus making the leveling smoother and reducing errors.
[0039] In summary, this application includes at least one of the following beneficial technical effects:
[0040] 1. The underside of the bonding slab and the composite slab are bonded together. The traction rod passes through the gap between the composite slabs and then through the tension rod and is locked with the traction nut. The traction rod is locked to the composite slab. Finally, the support bar is installed on the upper end of the traction rod. Since the traction rods are of the same length, after the support bar is installed at the top of the traction rod, the support bar and the bonding slab are parallel to each other. Therefore, the support bar and the composite slab are also parallel structures. Thus, when the leveling mechanism vibrates from the upper side of the limiting component, the support bar is used as a reference plane. The vibrated concrete is flush with the upper side of the support bar, which makes the concrete poured on the upper side of the composite slab more evenly laid. After leveling, the unevenness of the floor surface caused by uneven concrete laying is reduced. Attached Figure Description

[0051] The following is in conjunction with the appendix Figure 1 - Appendix Figure 8 This application will be described in further detail below.
[0052] Example 1: A construction device for leveling cast-in-place floor slabs, referring to... Figure 1 It includes at least two limiting components 2 for limiting the thickness of concrete, the limiting components 2 being fixed between adjacent composite plates 1; a support strip 25 is fixed at the upper end of the limiting components 2, the support strip 25 being parallel to the composite plate 1; and a leveling mechanism 3 for leveling the concrete is placed on the upper side of the support strip 25.
[0053] Reference Figure 2 The leveling mechanism 3 includes a vibrating frame 31. A leveling bucket 32 for leveling concrete is hinged to one side of the vibrating frame 31. The leveling bucket 32 is controlled to rotate by a first rotating member 34 (which is a motor) fixed to the vibrating frame 31, so that the leveling bucket 32 is kept at a height of one to three centimeters above the upper side of the support bar 25. A scraper plate 33 for scraping the vibrated concrete is hinged to the vibrating frame 31 away from the leveling bucket 32. The scraper plate 33 is controlled to rotate by a second rotating member 35, which controls the leveling process. The plate 33 flips over (the second flipping component 35 is a motor) to control the scraper plate 33 to fit against the support strip 25. When the leveling mechanism 3 moves on the limiting component 2, the leveling bucket 32 is in front and the scraper plate 33 is behind. The leveling bucket 32 scrapes away the excessively high part of the concrete. After vibration, the concrete height is reduced. Then the scraper plate 33 uses the upper surface of the support strip 25 as a reference to level the concrete surface, so that the leveled cast-in-place floor slab is more flat and reduces the occurrence of unevenness of the floor surface after leveling due to uneven concrete laying.
[0054] During the movement of the vibrating frame 31, the leveling bucket 32 shovels the part of the concrete that is higher than the set height into the leveling bucket 32. When it moves to a lower position of the concrete, the concrete in the leveling bucket 32 automatically flows out of the leveling bucket 32 under the action of vibration and is supplemented to the lower position of the concrete, so that the concrete is flatter after leveling.
[0055] Refer to Figure 3 , Figure 4 , the limiting component 2 includes a fitting plate 21 fixed to the lower side of the laminated board 1. A plurality of traction rods 22 for passing through the laminated board 1 are vertically fixed on the fitting plate 21. A tension rod 23 is installed on the upper side of the laminated board 1. The traction rod receives the threaded rod 24 to lock the traction rod 22 on the tension rod 23. A support bar 25 is fixedly connected to the upper end of the traction rod 22. The lengths of the traction rods 22 are equal. After the support bar 25 is installed, it is parallel to the laminated board 1, so that the thickness of the concrete is uniform after leveling with the upper surface of the support bar 25 as the reference; thus, the floor surface of the cast-in-place floor slab after leveling is flatter, reducing the occurrence of unevenness on the floor surface after leveling caused by uneven laying of concrete.
[0056] During the installation process of the fitting plate 21, the lower side of the laminated board 1 is wetted, and then a layer of cement is covered on the upper side of the fitting plate 21. After the fitting plate 21 is fixed, a closed structure is formed with the lower side of the laminated board 1, reducing the leakage of concrete during the pouring of concrete. At the same time, there is no need to install templates at the splicing positions between the laminated boards 1, reducing the installation of templates.
[0057] Refer to Figure 5 , after the fitting plate , the traction rod 22, the tension rod 23 and the traction nut 24 are locked, they form a "soil" character structure, generating a clamping force on the upper and lower sides of the laminated board 1, making the connection between the laminated boards 1 more stable.
[0058] Refer to Figure 6 , the laminated board 1 includes a concrete bottom slab 11, prestressed steel bars 12 embedded in the concrete bottom slab 11 and extending out of the concrete bottom slab 11, a concrete truss 13 fixed on the concrete bottom slab 11, and a concrete tie bar 14 fixed on the upper side of the concrete truss 13; the concrete truss 13 is a triangular structure, the lower side is fixedly connected to the prestressed steel bar 12 buried in the concrete bottom slab 11, and the upper end is fixedly connected to the concrete tie bar 14, so that the structure is more stable after the concrete is combined with the concrete truss 13 and the concrete tie bar 14 after solidifying on the upper side of the laminated board 1.
[0059] Refer to Figure 4 , Figure 5A snap-fit groove 26 is provided on the lower side of the support bar 25 to connect with the traction rod 22, so as to facilitate quick connection between the support bar 25 and the traction rod 22. After the support bar 25 and the traction rod 22 are connected, the support bar 25 and the traction rod 22 are welded together to make the support bar 25 more firmly fixed.
[0060] Two abutment rods 27 are fixed on the lower side of the support bar 25. The abutment rods 27 are distributed on both sides of the traction rod 22. An abutment groove 28 is provided on the upper side of the tension rod 23 where it connects with the abutment rod 27, making it easier to insert the abutment rod 27. After the abutment rod 27 is inserted into the abutment groove 28, it is welded again. Under the action of the abutment rod 27 and the traction rod 22, the support bar 25 is connected to the traction rod 22 at multiple points. The multi-point support makes the support bar 25 more stable.
[0061] To make the installation of the limiting component 2 more secure, connecting grooves 29 are made at both ends of the tension rod 23 to connect with the concrete frame 13. After the connecting grooves 29 are connected to the concrete frame 13, the tension rod 23 is welded and fixed together with the concrete frame 13, so that the limiting component 2 is more secure.
[0062] Reference Figure 7 Figure 8 shows a pair of vibration generating components 36 symmetrically installed on the vibrating frame 31 to generate vibration in the vibrating frame 31. The vibration generating components 36 include a rotating shaft 361 rotatably mounted on the vibrating frame 31, multiple vibration-generating polarizing plates 362 fixed on the rotating shaft 361, and a driving component 363 (the driving component 363 is a drive motor) fixed on the vibrating frame 31 to drive the rotating shaft 361 to rotate. The driving component 363 drives the rotating shaft 361 to rotate, and the vibrating frame 31 vibrates under the action of the inertia of the polarizing plates 362, expelling gas from the concrete.
[0063] Reference Figure 9 A circular vibration chamber 365 is provided inside the vibrating frame 31. The rotating shaft 361 and the polarizing plate 362 are set inside the vibration chamber 365. The two ends of the vibration chamber 365 are sealed by the sealing ring 366, which can reduce the influence of sand and gravel on the vibration generating component 36 and make the leveling mechanism 3 work more stably.
[0064] Reference Figure 7 In order to facilitate the movement of the leveling mechanism 3, a battery 37 is fixed on the vibrating frame 31 to supply power to the drive component 363, the first flipping component 34 and the second flipping component 35. The use of wires is reduced by powering the battery 37, so that the leveled concrete is not scratched by the wires.
[0065] A pair of traction ears 364 for connecting traction ropes are fixedly connected to both sides of the upper end of the vibrating frame 31; the vibrating frame 31 is moved with the traction rope installed on the traction ears 364 in the direction of the leveling bucket 32 in front and the scraper plate 33 behind, so as to vibrate and level the concrete.
[0066] Reference Figure 8 The bottom of the vibratory frame 31 is a flat structure, which contacts the upper side of the support bar 25. The two sides are raised structures. The raised structures first contact the concrete above the bottom of the vibratory frame 31. Under the action of vibration, the gas inside the concrete above the support bar 25 is discharged, the height decreases, and it is flush with the upper side of the support bar 25.
[0067] The implementation principle of this application embodiment is as follows:
[0068] The limiting component 2 is fixedly installed between the composite slabs 1 and 2. The leveling mechanism 3 is placed on the support bar 25 to vibrate the concrete, expelling the air from the concrete and making the concrete more compact and the resulting structure more stable. A leveling bucket 32 is set on one side of the vibrating frame 31, and a scraper plate 33 is set on the side of the vibrating frame 31 away from the leveling bucket 32. As the leveling mechanism 3 moves along the support bar 25, the leveling bucket 32 is in front and the scraper plate 33 is behind. The leveling bucket 32 removes the excessively high part of the concrete, leaving a height of 1 to 3 cm from the top of the support bar 25. After the leveling mechanism 3 vibrates, the concrete height drops to a position flush with the upper surface of the support bar 25, and then is leveled by the scraper plate 33. This reduces the occurrence of uneven floor surface after leveling due to uneven concrete laying.
[0069] This application also discloses a construction method for a cast-in-place floor slab leveling construction device. The construction method using the aforementioned cast-in-place floor slab leveling construction device includes the following steps:
[0070] Step 1, Installation of Limiting Component 2: First, pass the traction rod 22 through the gap between the composite plates 1, then pass the tension rod 23 through the traction rod 22, so that the bonding plate 21, the traction rod 22 and the tension rod 23 form an "T" structure, and the composite plate 1 is clamped between the tension rod 23 and the bonding plate 21; then lock the traction nut 24 to the traction rod 22, so that the tension rod 23 and the bonding plate 21 are clamped together; finally, snap the support bar 25 onto the upper end of the traction rod 22.
[0071] Step 2, cleaning the upper surface of the composite board 1: First, use a broom to clean the sand off the surface of the composite board 1, and then use a vacuum cleaner to clean the fine dust off the upper surface of the composite board 1.
[0072] Step 3, Wet the surface of the composite board 1: Spray water onto the surface of the composite board 1 using a spraying device to allow the composite board 1 to fully absorb water.
[0073] Step 4: Pour concrete onto the upper side of composite slab 1: Pour concrete onto the upper side of composite slab 1 using a concrete pump. The thickness of the concrete should be one to three centimeters higher than the upper side of the support strip 25.
[0074] Step 5, Adjustment of leveling mechanism 3: Place the vibrating frame 31 on the concrete, with the vibrating frame 31 perpendicular to the support bar 25 and the lower side of the vibrating frame 31 parallel to the support bar 25.
[0075] Step 6, Adjustment of leveling bucket 32: Control the leveling bucket 32 to rotate by the first tilting component 34 so that the lower side of the leveling bucket 32 is one to three centimeters higher than the upper side of the support bar 25;
[0076] Step 7: Adjust the scraper plate 33; control the scraper plate 33 to fit against the upper side of the support bar 25 by using the second flipping component 35.
[0077] Step 8: The leveling mechanism 3 moves; the traction rope is locked to the traction ear 364, and the leveling mechanism 3 is pulled by the traction device to move the leveling mechanism 3 to compact the concrete. At the same time, the leveling bucket 32 pushes the concrete that is higher than the set height to the lower position; the scraper plate 33 scrapes the vibrated concrete to level it during the movement.
