Description

Technical Field

[0001] This invention relates to a green construction equipment and method for pouring and tamping post-cast structural columns, belonging to the field of building construction technology. Background Technology

[0002] Green construction refers to construction activities that, while ensuring basic requirements such as quality and safety, maximize resource conservation and minimize negative environmental impacts through scientific management and technological advancements, achieving "four savings and one environmental protection": energy conservation, land conservation, water conservation, material conservation, and environmental protection. Aluminum formwork is a commonly used formwork material in building construction. Due to its advantages such as light weight, high strength, and durability, it is widely used in green construction, for example, in the construction of post-cast structural columns.

[0003] When constructing post-cast structural columns, aluminum formwork typically only has a pouring port at the top, and the operational space above the pouring port is limited by the space constraints of the interior ceiling slab. Therefore, after the concrete is poured, it is impossible to use a traditional vibrator for compaction. The traditional construction method is to manually tap the formwork during the pouring process to compact the concrete through vibration transmission. This construction method not only has poor vibration effect, but more importantly, the formwork of the structural column is built close to the wall. While vibrating to compact the concrete, it also vibrates the masonry wall, causing deformation or displacement of the wall, which poses a risk to the building's quality and construction safety.

[0004] To address this, some existing patents have been disclosed to solve the drawbacks of traditional construction techniques. For example, Chinese patent application CN110409713A describes a method for segmented pouring of concrete for structural columns and a structure for pouring concrete for structural columns. The method involves opening at different heights in the formwork and pouring and vibrating the concrete segment by segment. While this method can achieve the purpose of inserting a traditional vibrator into the formwork to vibrate the concrete, it is limited to the pouring of the lower and middle structural columns. Since the vibrator's working end is a rigid rod structure with a considerable length, the pouring of the upper structural columns is still restricted by the space of the top floor slab, making it difficult to operate smoothly. Furthermore, multiple openings in the formwork require sealing devices, which increases the complexity of the formwork structure and the cumbersomeness of the operation.

[0005] Furthermore, for example, the Chinese patent application CN215631726U for a structural column grouting vibration device involves attaching the vibration mechanism to the end of the concrete slurry pumping pipe. The pumping pipe extends into the formwork, thereby driving the vibration mechanism to extend into the formwork for vibration. While this solution addressed the space limitation imposed by the top floor slab in the aforementioned prior art and could vibrate concrete at different depths or heights, it essentially uses the concrete pumping pipe as an attachment and traction device for vibration. The concrete pumping pipe needs to transport slurry, has a large working mass, and requires a relatively large pipe diameter. Vibration construction typically involves a reciprocating insertion and extraction method to compact the slurry. Obviously, controlling the vibration mechanism through the aforementioned concrete pumping pipe to achieve the reciprocating insertion and extraction operation is inconvenient and even impractical.

[0062] The present invention will now be described in detail with reference to the accompanying drawings and specific embodiments.

[0063] Example 1

[0064] See Figure 1 , 2 4. This invention discloses a green construction equipment for pouring concrete for post-cast structural columns, including an assembled aluminum formwork component 100, a suspended vibrating device 200, and a concrete pumping device 900 for pouring concrete slurry.

[0065] The modular aluminum formwork component 100 includes several sets of unit aluminum formwork 110 that can be stacked and assembled, and formwork support components 120 for supporting and constraining the unit aluminum formwork 110. The top unit aluminum formwork 110 is provided with a chute funnel 130. During construction, according to the height of the structural column, several unit aluminum formwork 110s of appropriate number and length are selected and spliced ​​together. The unit aluminum formwork 110 with the chute funnel 130 is set at the top of the modular aluminum formwork component 100. Subsequently, concrete slurry is poured and vibrated through the chute funnels 130 on both sides of the unit aluminum formwork 110.

[0066] like Figure 3 As shown, the unit aluminum mold 110 includes a symmetrically arranged front aluminum mold 111 and a rear aluminum mold 112. Both the upper and lower ends of the outer walls of the front aluminum mold 111 and the rear aluminum mold 112 are provided with back ribs 113. The back ribs 113 can be square tubes, and bolt holes are provided on the back ribs 113. The two back ribs 113 abutting each other are connected and locked together by a template pin 114. The template pin 114 includes a pin post and a pin plate. In use, the pin post is passed through the bolt holes of both back ribs 113 simultaneously. The pins are radially pierced through the pin column to prevent backlash, and the pins are wedge-shaped to further tighten and prevent loosening. The pins and pins used for template connection are existing technologies, and will not be described in more detail. The upper part of the front aluminum template 111 and the rear aluminum template 112 is provided with a slot 115. There are two chute funnels 130, which are respectively connected to the outside of the two slots 115. The chute funnel 130 used for pouring concrete slurry is a V-shaped sloping chute, which can successfully guide the concrete slurry into the template by using its sloping bottom surface.

[0067] like Figure 4 As shown, the formwork support components 120 are distributed on both sides of the assembled aluminum formwork component 100. The formwork support component 120 includes at least two telescopic support rods 121. The lower fixed ends of each telescopic support rod 121 are hinged to a fixed hinge seat 122. The upper support ends of each telescopic support rod 121 are hinged to a support hinge seat 123. The fixed hinge seat 122 can be fixedly installed on the lower floor slab 300 by expansion bolts. Each support hinge seat 123 can be fixedly installed on different unit aluminum formwork 110 by bolts. In use, the unit aluminum formwork 110 uses at least two telescopic support rods 121 of appropriate length on one side to position and support the upper and lower ends respectively. The spacing, position and verticality of the front aluminum formwork 111 and the rear aluminum formwork 112 are determined by adjusting the length of the two telescopic support rods 121 respectively.

[0068] Specifically, the telescopic support rod 121 includes a double-ended threaded sleeve 1211. Telescopic screws 1212 are screwed to both ends of the double-ended threaded sleeve 1211. The ends of the two telescopic screws 1212 are hinged to a fixed hinge seat 122 and a support hinge seat 123, respectively. A double-eared handle 1213 is provided on the outer wall of the double-ended threaded sleeve 1211. The threads of the two telescopic screws 1212 have opposite directions of rotation. Rotating the double-ended threaded sleeve 1211 controls the synchronous extension and retraction of the telescopic screws 1212 at both ends. In use, the length of the telescopic support rod 121 can be adjusted by operating the double-eared handle 1213 to rotate the double-ended threaded sleeve 1211.

[0069] like Figure 5 As shown, the suspended vibratory compaction device 200 includes a shuttle-shaped vibratory compaction device 210 and a lifting traction rope 220 connected to the shuttle-shaped vibratory compaction device 210. It also includes a suspension frame 230 for suspending support and controlling the winding and release of the lifting traction rope 220. The lifting traction rope 220 pulls and controls the shuttle-shaped vibratory compaction device 210. During construction, it can be inserted into the template to simulate the up-and-down reciprocating insertion and extraction operation of a traditional vibratory compaction rod.

[0070] like Figure 6 As shown, when the vibrating device is working, it needs to be inserted into the formwork cavity of the structural column from the slot at the top of the formwork and perform reciprocating up and down insertion and extraction activities to simulate manual hand-held vibration. Since the cross-sectional size of the formwork cavity is small and contains components such as steel cages, the vibrating device needs to be able to move flexibly up and down in this working environment.

[0071] Therefore, the shuttle-shaped vibrating device 210 includes a shuttle-shaped outer shell 211, which is an olive-shaped structure that is large in the middle and small at both ends. This makes it easier for the tip to guide the device through the narrow gaps in the steel cage when it moves up and down. A double-headed vibrating motor 213 is fixedly installed in the middle of the inner cavity of the shuttle-shaped outer shell 211 through a motor bracket 212. Each of the two output shafts of the double-headed vibrating motor 213 is connected to an eccentric vibrating block 214. The lifting traction cable 220 is connected to the upper end of the shuttle-shaped outer shell 211 and is also electrically connected to the double-headed vibrating motor 213 for power supply. When the device is working, the double-headed vibrating motor 213 is started, which drives the eccentric vibrating blocks 214 at both ends to rotate at high speed. The high-frequency rotation using centrifugal force generates a vibration effect.

[0072] Furthermore, since the shuttle-shaped vibrating device 210 can be quickly lifted and pulled by the lifting traction cable 220, and the shuttle-shaped vibrating device 210 needs to rely on its own weight and vibration effect to sink when it descends, in the environment covered by concrete, especially when the viscosity of the concrete slurry is high or / and close to the compaction state, its sinking response speed is slow and it is easy to have sinking deviation problems. The working mode of the shuttle-shaped vibrating device 210 needs to realize reciprocating up and down insertion and extraction. In order to ensure construction efficiency, it is necessary to solve the problem of the speed of the vibrating device moving up and down in the concrete slurry.

[0073] Therefore, the lower end of the shuttle-shaped outer shell 211 is a flat end, and a conical auger drill bit 215 is provided on the flat end. The conical auger drill bit 215 and the shuttle-shaped outer shell 211 form a complete olive-shaped external structure. A drilling drive motor 216 is fixedly installed inside the shuttle-shaped outer shell 211. The output shaft of the drilling drive motor 216 extends out of the lower end of the shuttle-shaped outer shell 211 and is connected to the conical auger drill bit 215. Through this structural design, while maintaining its original shuttle-shaped external structure, the shuttle-shaped vibrating device 210 can be actively pulled by the conical auger drill bit 215 during its sinking process. On the one hand, it can accelerate the sinking response speed of the shuttle-shaped vibrating device 210 and meet its high-efficiency working requirements of reciprocating up and down insertion and extraction. On the other hand, the vertically downward conical auger drill bit 215 can improve the problem of the shuttle-shaped vibrating device 210 being prone to deviation when sinking by its own weight.

[0074] Furthermore, due to the pointed structure of the shuttle-shaped vibrating device 210, the effect at both ends is relatively weak during actual vibration. The shuttle-shaped vibrating device itself is limited by its small size in the working environment, thus resulting in low vibration efficiency. The eccentric vibrating blocks 214 connected to the upper and lower ends of the double-headed vibrating motor 213 are installed in opposite orientations, based on the central symmetry of the center point of the double-headed vibrating motor 213. That is, when the motor rotates, the centrifugal force of the eccentric vibrating blocks 214 at the upper and lower ends is in opposite directions. In the working state, the upper and lower ends of the shuttle-shaped vibrating device 210 generate a swirling vibration effect on the surrounding concrete, such as... Figure 13 As shown, the dynamic trajectory of the central axis of the shuttle-shaped vibrating device 210 is similar to that of an hourglass, which just compensates for the small pointed ends of the shuttle-shaped vibrating device 210. Under dynamic conditions, the external trajectory of the shuttle-shaped vibrating device 210 can form a cylindrical shape, thereby eliminating the aforementioned problem of weak vibration effect caused by the small pointed ends of the shuttle-shaped vibrating device 210.

[0075] The lifting traction rope 220 is a multi-strand cable including a power supply wire and a load-bearing steel wire 217. The load-bearing steel wire 217 is slightly longer than the power supply wire. Since the lifting traction rope 220 needs to overcome the resistance of the concrete slurry to pull the shuttle-shaped vibrating device 210 during operation, the load-bearing steel wire 217 is built into it. When the working tension is high, the load-bearing steel wire 217 takes priority, thereby protecting the wire from being pulled apart or broken.

[0076] like Figure 7 As shown, the suspension frame 230 includes a longitudinal support column 231 and a transverse cantilever beam 232. The transverse cantilever beam 232 is installed on the upper end of the longitudinal support column 231 to form an L-shaped suspension frame structure. The transverse cantilever beam 232 is provided with several pulley blocks 233 for guiding and supporting the lifting traction cable 220. The lifting traction cable 220 passes through each pulley block 233 and extends to the front end of the transverse cantilever beam 232 and connects to the shuttle-shaped vibrating device 210 to adapt to the position of the upper end slot of the formwork of the structural column.

[0077] Both the longitudinal support column 231 and the transverse cantilever beam 232 adopt a telescopic structure, which can be adaptively adjusted according to the height of different structural columns and the distance between the equipment and the wall. The telescopic beam and column structure can be adjusted manually or by electric, hydraulic, or pneumatic means. The specific design of the telescopic rod structure and the telescopic principle are existing technologies and will not be described in detail in this embodiment.

[0078] In addition, the suspended vibratory compaction device 200 also includes a transport trolley 240, with longitudinal support columns 231 fixedly installed on the transport trolley 240. The transport trolley 240 is equipped with a placement platform 250, and a power supply control cabinet 260 is installed on the placement platform 250. The lifting traction cable 220 is electrically connected to the power supply control cabinet 260.

[0079] like Figure 7 As shown, to realize the winding and releasing operation of the lifting traction rope 220, the suspended vibrating device 200 also includes a winding mechanism 270, which is installed on the longitudinal support column 231. The winding mechanism 270 includes a hollow shaft 271 with one end fixed to the longitudinal support column 231. An I-beam drum 272 is rotatably mounted on the hollow shaft 271 through a bearing. A handle 273 is rotatably mounted on the outer wall of one side plate of the I-beam drum 272. The lifting traction rope 220 is wound on the I-beam drum 272, and the wound end passes through the inner cavity of the hollow shaft 271 and is electrically connected through a conductive slip ring 274. The conductive slip ring 274 is designed to prevent the lifting traction rope 220 from twisting. During operation, the winding and releasing operation of the lifting traction rope 220 can be driven by rotating the I-beam drum 272 through the handle 273.

[0080] like Figure 8-10As shown, since the shuttle-shaped vibrating device 210 needs to be inserted into the inner cavity of the template during operation, it uses a reciprocating up-and-down insertion method to simulate manual hand-held vibration. After the shuttle-shaped vibrating device 210 is inserted into the inner cavity of the template, the construction operator cannot directly observe the current height of the shuttle-shaped vibrating device 210 from the outside. During the alternating operation of retraction and lifting, it is quite difficult to judge the actual height position of the shuttle-shaped vibrating device 210 based on the operator's memory.

[0081] Therefore, the suspended vibratory compaction device 200 also includes a monitoring mechanism 280, which is mounted on the longitudinal support column 231;

[0082] The monitoring mechanism 280 includes an upper mounting column 281 and a lower mounting column 282, which are respectively fixed to the support column 231. The lower mounting column 282 is fitted with a clutch sleeve 284 at its cantilever end. A clutch sliding column 286 with a limit plate 285 at its end is fixedly provided on the end face of the lower mounting column 282 cantilever end. The clutch sliding column 286 passes through the end face of the clutch sleeve 284. A reset spring 287 is fitted on the clutch sliding column 286. The two ends of the reset spring 287 abut against the end face of the clutch sleeve 284 and the limit plate 285, respectively. A clutch pull ring 288 is provided on the end face of the clutch sleeve 284.

[0083] A first second-stage synchronous pulley 283 is rotatably mounted on the fixed end side of the lower mounting column 282, and a clutch roller 289 is rotatably mounted on the side wall of the clutch sleeve 284. The lifting traction rope 220 is arranged between the clutch roller 289 and the first second-stage synchronous pulley 283. A second second-stage synchronous pulley 2810 and a third second-stage synchronous pulley 2811 are rotatably mounted on the upper mounting column 281 and the longitudinal support column 231, respectively. The small pulley of the first second-stage synchronous pulley 283 and the large pulley of the second second-stage synchronous pulley 2810 are connected by a first winding rope 2812, and the small pulley of the second second-stage synchronous pulley 2810 and the large pulley of the third second-stage synchronous pulley 2811 are connected by a second winding rope 2813.

[0084] Two parallel fixed slide rods 2814 are provided on the front side of the longitudinal support column 231. The upper and lower ends of the two fixed slide rods 2814 are fixedly installed on the longitudinal support column 231 through slide rod seats 2815. A pointer lifting block 2816 is slidably installed on the two fixed slide rods 2814. The small wheel of the third second-stage synchronous pulley 2811 is connected to the pointer lifting block 2816 through a lifting winding rope 2817. A height scale line 2818 is fixedly installed on one side of the fixed slide rod 2814. A counterweight lead block 2819 is provided at the bottom of the pointer lifting block 2816 to provide its own weight and facilitate the timely return of the pointer lifting block 2816.

[0085] During operation, under normal conditions, the clutch roller 289 and the first and second stage synchronous pulleys 283 are in a state of mutual abutment and clamping of the lifting traction cable 220. When the lifting traction cable 220 is wound or released, the first and second stage synchronous pulleys 283 will roll accordingly, thereby changing the height position of the pointer lifting block 2816 through the wheel system transmission. When the clutch roller 289 is manually disengaged from the first and second stage synchronous pulleys 283, the lifting traction cable 220 is released from the clamped state, and its winding or releasing state will no longer change the height position of the pointer lifting block 2816 through the wheel system transmission. Based on this working principle, before the concrete slurry is poured, The shuttle-shaped vibrating device 210 is inserted into the bottom of the template cavity. Note that during the descent of the shuttle-shaped vibrating device 210, when the clutch roller 289 separates from the first and second-stage synchronous pulleys 283, the pointer lifting block 2816 descends to its lowest point, and the shuttle-shaped vibrating device 210 also descends to the lowest point of the template cavity. Then, the clutch roller 289 and the first and second-stage synchronous pulleys 283 are controlled to abut against each other, clamping the lifting traction cable 220. When the lifting traction cable 220 is subsequently wound or released, it will cause the pointer lifting block 2816 to change its height position. The height position of the shuttle-shaped vibrating device 210 can be accurately determined through the side height scale line 2818. To ensure clamping and prevent detachment, the outer circumference of the clutch roller 289 and the first and second-stage synchronous pulleys 283 is provided with a cable-holding groove that matches the outer diameter of the lifting traction cable 220.

[0086] When the clutch roller 289 is disengaged from the first and second stage synchronous pulleys 283, the clutch pull ring 288 is manually pulled outward, causing the clutch sleeve 284 to move outward against the spring force of the return spring 287. Since the clutch roller 289 is mounted on the clutch sleeve 284, the clutch roller 289 will move outward with the clutch sleeve 284, increasing the distance between the clutch roller 289 and the first and second stage synchronous pulleys 283, thus achieving disengagement. Similarly, when clamping is required, the clutch pull ring 288 is released, and the clutch sleeve 284 will automatically return to its original position under the return spring force of the return spring 287, decreasing the distance between the clutch roller 289 and the first and second stage synchronous pulleys 283, thus achieving clamping.

[0087] The various wheel components shown in the figure are actually for adjusting the transmission ratio. The lifting height of the shuttle vibrating device 210 needs to be reflected on the surface of the device's column through a scale in the design of this device. In order to facilitate observation, the height of the scale area is limited, and the ratio of the scale height to the actual height cannot be 1:1. Therefore, the transmission ratio is changed through the second second-order synchronous wheel 2810, the third second-order synchronous wheel 2811, and the first winding rope 2812. For example, a transmission ratio of 10:1 is used. When the lifting height of the shuttle vibrating device 210 is 10cm, the lifting height of the pointer lifting block 2816 is 1cm. This ensures accurate monitoring while facilitating observation and scale area layout.

[0088] In this device mechanism, the pointer lifting block 2816 can slide freely up and down on the fixed slide bar 2814. The upward traction force is provided by the lifting traction cable 220 driving the wheel system transmission, and the downward force is provided by its own weight and the counterweight lead block 2819. When the lifting traction cable 220 is wound up and drives the shuttle-shaped vibrating device 210 to rise, the pointer lifting block 2816 rises accordingly according to the transmission ratio. Conversely, when the lifting traction cable 220 is released and causes the shuttle-shaped vibrating device 210 to fall, the pointer lifting block 2816 falls accordingly according to the transmission ratio.

[0089] like Figure 11-12 As shown, since the shuttle-shaped vibrating device 210 needs to be operated by reciprocating up and down insertion and withdrawal to simulate manual hand-held vibration, it is designed for ease of operation and labor saving.

[0090] The suspended vibratory compactor 200 also includes a compaction mechanism 290, which is mounted on a longitudinal support column 231.

[0091] The tamping mechanism 290 includes a mounting plate 291 fixed to a longitudinal support column 231. A tamping roller 292 is rotatably mounted on the fixed end side of the mounting plate 291, and a notched disc wheel 293 is rotatably mounted on the cantilever end side of the mounting plate 291. One edge of the notched disc wheel 293 has a notch 294. When the non-notched part of the circumference of the notched disc wheel 293 is close to mesh, it can clamp the lifting traction cable 220. A tamping motor 295 for driving the notched disc wheel 293 is mounted on the back of the mounting plate 291. In order to ensure clamping and prevent detachment, the outer circumference of the notched disc wheel 293 and the tamping roller 292 is provided with a cable clamping groove that matches the outer diameter of the lifting traction cable 220.

[0092] When reciprocating vibration is required, the lifting traction cable 220 is inserted into the groove between the notched disc wheel 293 and the tamping roller 292. The tamping motor 295 is started to drive the notched disc wheel 293 to rotate. When the non-notched part of the notched disc wheel 293 is close to the tamping roller 292, the lifting traction cable 220 is clamped and driven to wind up. When the notched disc wheel 293 rotates to the notched part being close to the tamping roller 292, the lifting traction cable 220 is released. This realizes the reciprocating winding and releasing of the lifting traction cable 220, which realizes the reciprocating lifting of the shuttle-shaped vibrating device 210 to simulate manual hand-held vibration. Of course, when the tamping mechanism 290 is not needed, the tamping motor 295 can be stopped by controlling the notched disc wheel 293 so that the notch 294 faces the tamping roller 292.
