Description

Technical Field

[0001] This invention relates to the field of flat slab construction technology, specifically a construction device for large-span flat slabs. Background Technology

[0002] Flat slabs are slab-column structural systems that eliminate primary and secondary beams, with the slab directly supported by columns or column capitals. Loads are transferred directly to the foundation through the slab, column capitals, and columns. They feature flat bottoms, high headroom, and good space utilization. They are available in solid flat slabs, hollow slabs, and prestressed flat slabs. The column grid is usually square or near-square, with a length-to-span ratio generally not exceeding 1.5. The slab thickness is not less than 150mm. Column capitals or support plates are installed at the top of the columns to enhance punching shear resistance. Double-layer, two-way reinforcement is used, and hidden beams are added in key areas for reinforcement. Construction is mainly by cast-in-place, requiring proper formwork support, rebar tying, hollow inner formwork fixing, and concrete vibration. They are suitable for large-span, large-space buildings such as garages, shopping malls, and factories.

[0003] In the process of concrete pouring for large-span flat slabs, a pouring device is needed to pour the concrete into the formwork of the slab. However, current construction devices typically use a single discharge port to discharge the delivered concrete, resulting in poor concrete uniformity. Furthermore, additional concrete vibration is required after pouring, making the construction efficiency of flat slab pouring low, affecting the construction schedule and quality. To address the above-mentioned technical deficiencies of existing technologies, a construction device for large-span flat slabs is provided to solve these problems. Summary of the Invention

[0004] The purpose of this invention is to provide a construction device for large-span flat slabs to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: A construction device for large-span flat slabs includes an installation frame and a horizontal frame. A U-shaped frame is mounted on the installation frame, and a drive assembly is installed on the installation frame to drive the U-shaped frame to reciprocate relative to the installation frame. A sliding adjustment assembly is installed inside the installation frame, and an adjustment seat is mounted on the sliding adjustment assembly. A pair of rotating frames are rotatably mounted on the adjustment seat. A rotating sleeve is rotatably mounted at the end of each rotating frame away from the adjustment seat. A rotating column is vertically slidably mounted on the rotating sleeve, and a vibrating frame is mounted at the lower end of the rotating column. The rotating frame has a slotted hole on which a sliding... A pin is installed at the end of the U-shaped frame. A guide strip hole is opened on the horizontal frame.

A horizontal pipe is fixed on the hanger. A corrugated pipe communicating with the horizontal pipe is installed on the horizontal pipe. Several discharge pipes communicating with the interior of the horizontal pipe are installed at the bottom of the horizontal pipe.

[0006] As an improvement of the present invention: the drive assembly includes a wheel rotatably mounted on the mounting frame, a connecting rod eccentrically hinged to the wheel, and one end of the connecting rod away from the wheel is hinged to the U-shaped frame.

[0007] As an improvement of the present invention: the drive assembly further includes a motor fixed on the mounting bracket, and the output shaft of the motor is connected to the rotating wheel via a pulley mechanism.

[0008] As an improvement of the present invention: the sliding adjustment assembly includes a threaded sleeve block fixed on the adjustment seat, a threaded rod rotatably mounted on the mounting frame is threadedly connected to the threaded sleeve block, an adjustment wheel is fixed to the end of the threaded rod, and a hand hole corresponding to the adjustment wheel is provided on the mounting frame.

[0009] As an improvement of the present invention: the excitation assembly includes a plurality of protrusions fixed at equal intervals on the horizontal frame, a guide wheel that abuts and matches the protrusions is fixed on the sliding frame, a tray is fixedly sleeved on the rotating column, a top plate is fixedly sleeved on the rotating sleeve, and a spring ring is fixed between the top plate and the tray.

[0010] As an improvement of the present invention: the excitation assembly further includes a transmission gear fixedly sleeved on the rotating sleeve, a spur rack that meshes with the transmission gear is fixed on the horizontal frame, and a retaining strip is fixed to the side wall of the rotating column, the retaining strip being slidably embedded in the inner wall of the rotating sleeve.

[0012] As an improvement of the present invention: a connecting plate is fixed to one end of the mounting bracket away from the horizontal frame.

[0013] Compared with the prior art, the beneficial effects of the present invention are: This invention uses multiple discharge pipes to evenly and disperse the concrete pumped into the horizontal pipe, effectively preventing the concrete from falling in small areas. The drive component drives the rotating frame to swing clockwise and counterclockwise alternately, which in turn drives the hanger to perform linear reciprocating motion. This ensures that the concrete discharged from the discharge pipes is evenly dispersed and poured, greatly improving the concrete pouring quality and construction efficiency of large-span flat slabs.

[0014] 2. The vibrating frame set in this invention, driven by the excitation component, can not only vibrate up and down along the vertical direction with the rotating column, but also rotate clockwise and counterclockwise alternately due to the meshing transmission of the transmission gear and the linear reciprocating motion of the transmission gear relative to the horizontal frame. This allows the concrete poured in the formwork of the large-span flat slab to be vibrated in a timely manner, realizing the integrated synchronous operation of concrete pouring and vibration, which greatly improves the construction efficiency and quality of flat slab pouring.

[0018] First embodiment: Please refer to the appendix Figure 1 -Appendix Figure 7 A construction device for large-span flat slabs includes an installation frame 1 and a horizontal frame 5. A U-shaped frame 6 is mounted on the installation frame 1. A drive assembly for driving the U-shaped frame 6 to reciprocate relative to the installation frame 1 is also mounted on the installation frame 1. A sliding adjustment assembly is installed inside the installation frame 1. An adjustment seat 18 is mounted on the sliding adjustment assembly. A pair of rotating frames 7 are rotatably mounted on the adjustment seat 18. A rotating sleeve 21 is rotatably mounted at the end of each rotating frame 7 away from the adjustment seat 18. A rotating column 12 is vertically slidably mounted on the rotating sleeve 21. A vibrating frame 9 is mounted at the lower end of the rotating column 12. A strip-shaped hole 11 is opened on the rotating frame 7, and a component fixed to the U-shaped frame 6 is slidably mounted on the strip-shaped hole 11. The end pin 8, the horizontal frame 5 has a guide strip hole 29, the rotating sleeve 21 slides through the guide strip hole 29, the rotating sleeve 21 is fixedly sleeved with a limiting plate 24 that is slidably embedded on the horizontal frame 5, the horizontal frame 5 is slidably mounted with a sliding frame 20, the rotating column 12 is rotatably mounted on the sliding frame 20, the sliding frame 20 and the horizontal frame 5 are equipped with an excitation component for driving the vibration frame 9 to vibrate, the horizontal frame 5 is fixed with a hanger 28, the hanger 28 is fixed with a horizontal pipe 2, the horizontal pipe 2 is installed with a corrugated pipe 3 that communicates with it, the bottom of the horizontal pipe 2 is installed with several discharge pipes 4 that communicate with its interior, and the end of the mounting frame 1 away from the horizontal frame 5 is fixed with a connecting plate 27.

[0019] When constructing large-span flat slabs using this device, the connecting plate 27 is connected to the moving mechanism. The movement of the moving mechanism drives the construction device to move linearly, thereby moving the horizontal frame 5 and the horizontal pipe 2. The device is connected to an external concrete pumping mechanism through the corrugated pipe 3. Concrete enters the horizontal pipe 2 from the corrugated pipe 3 and is then discharged through multiple discharge pipes 4, thus enabling the pouring of the flat slab formwork.

[0020] The drive assembly of this device includes a rotating wheel 31 rotatably mounted on the mounting frame 1. A connecting rod 17 is eccentrically hinged to the rotating wheel 31. The end of the connecting rod 17 away from the rotating wheel 31 is hinged to the U-shaped frame 6. The drive assembly also includes a motor 19 fixed on the mounting frame 1. The output shaft of the motor 19 is connected to the rotating wheel 31 through a pulley mechanism 32.

[0021] With the above configuration, the motor 19 drives the rotating wheel 31 to rotate through the belt pulley mechanism 32. During the rotation, the rotating wheel 31 pulls the connecting rod 17, which causes the U-shaped frame 6 to reciprocate relative to the mounting frame 1. This causes the U-shaped frame 6 to drive the rotating frame 7 to rotate through the pin 8, and causes the horizontal frame 5 to slide reciprocally relative to the mounting frame 1. At this time, the position of the discharge pipe 4 can be adjusted back and forth, so that the discharge area of ​​the concrete can be automatically adjusted, and the concrete pouring is more uniform.

[0022] In addition, the sliding adjustment assembly of this device includes a threaded sleeve block 26 fixed on the adjustment seat 18, a threaded rod 10 rotatably mounted on the mounting frame 1 and threaded connection on the threaded sleeve block 26, an adjustment wheel 25 fixed at the end of the threaded rod 10, and a hand hole 30 corresponding to the adjustment wheel 25 is provided on the mounting frame 1.

[0023] When it is necessary to adjust the maximum stroke range of the discharge pipe 4, the threaded rod 10 is driven to rotate by rotating the adjusting wheel 25. The threaded rod 10 drives the threaded sleeve block 26 and the adjusting seat 18 connected to it to move. At this time, the adjusting seat 18 can slide relative to the mounting frame 1, thus achieving the adjustment effect of the initial position of the adjusting seat 18. This facilitates adaptive adjustment according to the pouring area of ​​the flat slab, making the concrete pouring operation more convenient and efficient.

[0024] Second embodiment: Please refer to the appendix Figure 1 -Appendix Figure 7 In addition to the first embodiment, the vibration component in this construction device includes several protrusions 23 fixed at equal intervals on the horizontal frame 5, guide wheels 22 that abut and match the protrusions 23 are fixed on the sliding frame 20, a tray 34 is fixedly sleeved on the rotating column 12, a top plate 33 is fixedly sleeved on the rotating sleeve 21, and a spring ring 13 is fixed between the top plate 33 and the tray 34.

[0025] With the above settings, during the swinging process of the rotating frame 7, the rotating frame 7 drives the rotating sleeve 21 to slide relative to the horizontal frame 5, so that the limiting plate 24 on the rotating sleeve 21 slides and engages with the horizontal frame 5 to achieve guidance and limitation. During this process, the sliding frame 20 drives the guide wheel 22 installed on it to slide. The guide wheel 22 pushes against multiple protrusions 23 one by one, so that the rotating column 12 can move up and down in the vertical direction under the elastic support of the spring ring 13, so that the vibrating frame 9 can move up and down and vibrate the poured concrete, effectively improving the concrete pouring quality of the flat slab.

[0026] In addition, the excitation assembly also includes a transmission gear 16 fixedly sleeved on the rotating sleeve 21, a spur rack 15 fixed on the horizontal frame 5 that meshes with the transmission gear 16, and a retaining strip 14 fixed on the side wall of the rotating column 12, the retaining strip 14 being slidably embedded in the inner wall of the rotating sleeve 21.

[0027] Based on the above structural configuration, during the reciprocating motion of the rotating sleeve 21 relative to the horizontal frame 5, the transmission gear 16 meshes with the rack 15, enabling the transmission gear 16 to drive the rotating sleeve 21 to rotate. At this time, the rotating sleeve 21 drives the rotating column 12 to rotate through the clamping strip 14, and the rotating column 12 drives the vibrating frame 9 to rotate. This enables the vibrating frame 9 to vibrate the concrete poured into the formwork of the flat slab. Combined with the vertical reciprocating motion of the vibrating frame 9, air bubbles inside the concrete can be effectively eliminated, making the concrete densely bonded and eliminating phenomena such as honeycomb and pitting, thereby improving its strength and ensuring the quality of the flat slab.

[0028] In addition, the vibrating frame 9 is slidably sleeved on the rotating column 12, and a locking post 35 is threadedly connected to the vibrating frame 9. The end of the locking post 35 abuts against the side wall of the rotating column 12. The vibrating frame 9 can be vertically slidably adjusted relative to the rotating column 12. The vibrating frame 9 and the rotating column 12 are locked and fixed by the locking post 35, so that the initial height of the vibrating frame 9 can be adjusted to adapt to the concrete pouring thickness of the flat slab, ensuring that the concrete of the flat slab is fully vibrated and improving the construction quality of the flat slab.

[0029] In summary, this invention uses multiple discharge pipes 4 to evenly and disperse the concrete pumped into the horizontal pipe 2, effectively preventing the concrete from falling in small areas. The drive assembly drives the rotating frame 7 to alternately swing clockwise and counterclockwise, allowing the horizontal frame 5 to drive the hanger 28 in linear reciprocating motion. This ensures that the concrete discharged from the discharge pipes 4 is evenly distributed during pouring, significantly improving the concrete pouring quality and construction efficiency of large-span flat slabs. The vibrating frame 9, driven by the vibration assembly, not only vibrates vertically along with the rotating column 12, but also rotates clockwise and counterclockwise due to the meshing of the transmission gear 16 and the rack 15, and the linear reciprocating motion of the transmission gear 16 relative to the horizontal frame 5. This ensures timely vibration of the concrete poured into the large-span flat slab formwork, achieving integrated and synchronous operation of concrete pouring and vibration, greatly improving the construction efficiency and quality of flat slab pouring.
