Description

Technical Field

[0001] This application relates to the technical field of concrete construction, and in particular to an electric chute for cast-in-place horizontal concrete structures and its usage method. Background Technology

[0002] The chute method offers unparalleled speed advantages over other methods when pouring large volumes of concrete. It is particularly suitable for pouring large-volume concrete components.

[0003] Currently, for ultra-long horizontal concrete structures such as airport terminals, truck-mounted concrete pumps cannot cover the area during concrete pouring, while ground-mounted pumps are cumbersome to set up and have a slow pouring speed. After the ground-mounted pump and pump pipes are set up, concrete can only be poured in the area near the pump pipe outlet.

[0004] Once traditional chutes are erected, they have the drawback of being fixed in position and unable to be moved, and can only be used for large-volume concrete pouring in a certain area. Summary of the Invention

[0005] In order to facilitate high-speed pouring of concrete components in any area during long-distance concrete transportation, this application provides an electric chute for horizontal cast-in-place concrete structures and a method of using it.

[0006] In a first aspect, this application provides an electric chute for horizontal cast-in-place concrete structures, employing the following technical solution:

[0007] An electric chute for horizontal cast-in-place concrete structures includes a main chute, branch chutes, and a conveyor belt. The conveyor belt is laid inside the main chute along its length. A branch outlet is provided on the main chute. One end of the branch chute is located on the outer wall of the main chute, with its connection point at the branch outlet. A corrugated section is provided between the branch chute and the main chute, with one end connected to the main chute and the other end connected to the branch chute. The corrugated section is used to adjust the horizontal and vertical position of the branch chute relative to the main chute. Multiple branch outlets are provided on a single section of the main chute, with adjacent branch outlets spaced apart along the length of the main chute and staggered on both sides of the main chute wall. The main chute consists of multiple sections, with adjacent sections overlapping at different heights. Branch legs are provided on the branch chute for adjusting its vertical height.

[0008] By adopting the above technical solution, the overall chute is composed of a main chute and branch chutes, and concrete is transported using a conveyor belt. Tower cranes can be used for hoisting, which facilitates installation and disassembly. The specific installation position can be adjusted according to the actual needs of the site. By opening multiple diversion ports on the main chute, the position of the branch chute can be easily set. Furthermore, due to the presence of corrugated sections, the position of the branch chute can be adjusted relative to the main chute, not only in the horizontal direction but also in the vertical direction. This achieves the effect of facilitating high-speed pouring of concrete components in any area during long-distance concrete transportation. High-speed concrete transportation is achieved through the conveyor belt.

[0009] Optionally, a sealing plate is inserted and connected to the main channel. The sealing plate is slidably disposed with the main channel, and the sliding direction is vertical and it is inserted into the main channel. The sealing plate is used to open or block the diversion port.

[0010] By adopting the above technical solution, when the branch channel is not required for diversion, the diversion port can be blocked by the blocking plate. The opening or blocking of the diversion port further improves the effect of high-speed concrete casting in any area near the main channel.

[0011] Optionally, a baffle is fixed on the main channel. One end of the baffle is fixedly connected to the inner wall of one side of the main channel, and the other end is inclined along the direction close to the center line of the main channel and is at a distance from the inner wall of the other side of the main channel. The overall inclination direction of the baffle is opposite to the flow direction of the concrete in the main channel. Along the flow direction of the concrete in the main channel, the baffle is located downstream of the diversion port and close to the diversion port.

[0012] By adopting the above technical solution, when concrete is transported in the main channel, some of the concrete will be blocked by the baffle. The concrete blocked by the baffle will flow into the branch channel through the diversion port. The presence of the baffle provides guidance and diversion for the concrete to flow into the branch channel.

[0013] Optionally, an extension plate is inserted into the baffle, with one end of the extension plate being inserted into the baffle and the other end being inserted into the inner wall of the main channel. The extension plate and the baffle vertically separate the internal space of the main channel.

[0014] By adopting the above technical solution, if only part of the branch channel is needed on a single main channel, the interior of the main channel can be partitioned by inserting an extension plate and using a baffle, thereby reducing unnecessary flow paths of concrete in the main channel and improving the efficiency of concrete transportation.

[0015] Optionally, the upper surface of the conveyor belt is recessed, with the recess located in the middle of the belt surface.

[0016] By adopting the above technical solution, the concrete gradually approaches the middle of the conveyor belt itself, thereby reducing the phenomenon of mortar flowing down from the gap between the conveyor belt and the inner wall of the main trough, and reducing the occurrence of concrete segregation.

[0017] Optionally, the overlap length between adjacent main channels is not less than 200mm; along the concrete conveying direction, each section of the main channel is inclined from low to high from one end to the other.

[0018] By adopting the above technical solution, the 200mm length ensures stable concrete delivery after the overlap between adjacent main chutes. The inclined direction of the main chutes, along with the concrete delivery direction, effectively causes the concrete to continuously travel from low to high. Firstly, this reduces concrete segregation. When the chute is laid inclined from high to low, the flow speed of the concrete increases, leading to the separation of aggregate and mortar, i.e., segregation. This affects the quality and strength of the concrete. Conversely, when the chute is laid inclined from low to high, the flow speed of the concrete slows down, thus reducing segregation. Secondly, it reduces delivery resistance. When the chute is laid inclined from low to high, the resistance to concrete flow decreases, making delivery easier. This is because concrete must overcome gravity and friction to flow in the chute; when the chute is laid inclined from low to high, the direction of gravity is the same as the direction of concrete flow, thus reducing delivery resistance.

[0019] Optionally, the conveyor belt has slots on its surface, which are opened along the width of the conveyor belt. Multiple slots are opened, and adjacent slots are spaced apart along the length of the conveyor belt. A sealing plate is inserted and sealed at the end of a single main trough, and the sealing plate is located at the lower end of the single main trough after it is inclined.

[0020] By adopting the above technical solution, the slot enhances the adhesion of concrete to the conveyor belt surface, making the conveyor belt transport concrete more effortlessly, and the sealing plate prevents concrete from slipping off the inclined conveyor belt surface.

[0021] Optionally, a vibration motor is fixed to the outer wall of the support groove.

[0022] By adopting the above technical solution and starting the vibration motor, the support trench can be vibrated, which makes it easier for the concrete to slide out of the support trench more quickly. At the same time, due to the presence of the corrugated section, the vibration of the support trench can minimize the vibration impact on the main trench.

[0023] Optionally, the branch leg includes an inner leg and an outer leg. One end of the inner leg is hinged to a support groove ball, and the other end is inserted into the outer leg. The outer leg is provided with a positioning bolt for fixing the position of the outer leg and the inner leg.

[0024] By adopting the above technical solution, the total length of the branch legs in the vertical direction can be adjusted, thereby changing the vertical height of the support groove. Since one end of the inner leg is ball-jointed with the support groove, the four branch legs cooperate with each other. At the same time, with the corrugated section, the support groove can produce a multi-angle tilt state relative to the main groove in the horizontal direction, which is more in line with the needs of actual engineering phenomena and the operation is more flexible.

[0025] Secondly, this application provides a method for using an electric chute for horizontal cast-in-place concrete structures, employing the following technical solution:

[0026] A method for using an electric chute for horizontal cast-in-place concrete structures includes the following steps:

[0027] S1. Hoist multiple main channels to the concrete pouring site and arrange them in a staggered, overlapping manner.

[0028] S2. Connect the branch channel to the main channel;

[0029] S3. Concrete pouring begins at the farthest end of the area to be poured, following a reverse construction sequence.

[0030] S4. Remove the corresponding sealing plate, and then use the support trench to pour the concrete in the area near the main trench.

[0031] S5. After the main channel is poured, it can be removed in sections.

[0032] By adopting the above technical solution, the chute is divided into multiple main chute sections and multiple branch chute sections. It is easy to install and disassemble by tower crane, and its position can be moved according to the actual site conditions. It uses a conveyor belt powered by electricity to realize long-distance concrete transportation. The multiple branch chute sections form tree root-like branches to facilitate high-speed pouring of concrete components at any location.

[0033] In summary, this application includes at least one of the following beneficial technical effects:

[0034] 1. The overall chute consists of a main chute and branch chutes, and uses a conveyor belt to transport concrete. It can be lifted by a tower crane to facilitate installation and disassembly. The specific installation position can be adjusted according to the actual needs of the site. By opening multiple diversion ports on the main chute, it is easy to set the position of the branch chute. Furthermore, due to the presence of corrugated sections, the position of the branch chute can be adjusted relative to the main chute, not only in the horizontal direction but also in the vertical direction. This achieves the effect of high-speed pouring of concrete components in any area during long-distance concrete transportation. High-speed transportation of concrete is achieved through the conveyor belt.

[0035] 2. The corrugated section, combined with the inner leg, is connected to the support groove by a ball joint. This allows the support groove to tilt at multiple angles relative to the main groove in the horizontal direction, which better meets the needs of actual engineering phenomena and makes the operation more flexible.

[0036] 3. The inclined direction of the main channel and the direction of concrete conveying will actually cause the concrete to be conveyed repeatedly from low to high, which can reduce concrete segregation and reduce conveying resistance. Attached Figure Description

[0041] The following is in conjunction with the appendix Figures 1-3 This application will be described in further detail.

[0042] This application discloses an electric chute for horizontal cast-in-place concrete structures.

[0043] refer to Figure 1 An electric chute for cast-in-place horizontal concrete structures includes a main chute 1 and branch chute 2. The main chute 1 is provided in multiple sections, with adjacent main chute 1 sections overlapping. Each section of the main chute 1 has at least one branch chute 2 on each side, thus forming branches of the main chute 1 and expanding the concrete transport range. A conveyor belt 11 is laid along the length of the main chute 1 inside the main chute 1 to transport the concrete. A diversion port 12 is opened on the main chute 1, located on the chute wall of the main chute 1, for connecting the internal passage of the main chute 1 with the internal passage of the branch chute 2.

[0044] refer to Figure 1 and Figure 2Multiple branch outlets 12 are provided on a single main channel 1. Adjacent branch outlets 12 are spaced apart along the length of the main channel 1 and are staggered on both sides of the main channel 1. The number of branch outlets 12 corresponds to the number of branch channels 2 installed on the main channel 1. A baffle 3, a sealing plate 13 and an extension plate 31 are provided on the main channel 1. The sealing plate 13 is inserted into the main channel 1 and is also slidably disposed with the main channel 1. The sliding direction is vertical and it is inserted into the main channel 1. The insertion point of the sealing plate 13 is located at the branch outlet 12. After the sealing plate 13 is completely inserted into the main channel 1, the sealing plate 13 completely blocks the branch outlet 12.

[0045] refer to Figure 1 and Figure 2 Both the baffle 3 and the extension plate 31 are located inside the main channel 1. One end of the baffle 3 is fixedly connected to the inner wall of one side of the main channel 1, and the other end is inclined along the direction close to the center line of the main channel 1, with a distance between it and the inner wall of the other side of the main channel 1. The extension plate 31 fills this distance. One end of the extension plate 31 is inserted into the end of the baffle 3, and the other end of the extension plate 31 is inserted into the inner wall of the main channel 1. The insertion direction of the extension plate 31 is vertical. When the extension plate 31 is completely inserted into the baffle 3 and the inner wall of the main channel 1, the baffle 3 and the extension plate 31 block the conveying passage inside the main channel 1. The overall inclination direction of the baffle 3 is opposite to the flow direction of the concrete in the main channel 1 and along the flow direction of the concrete in the main channel 1. The baffle 3 is located downstream of the diversion port 12 and close to the diversion port 12.

[0046] refer to Figure 2 and Figure 3 Along the concrete conveying direction, each section of the main trough 1 is inclined from low to high from one end to the other. The overlap between adjacent main troughs 1 is a staggered overlap, that is, the starting end of the rear main trough 1 is also its lower end, placed below the end of the front main trough 1, which is also below the higher end of the front main trough 1. The length of the staggered overlap between adjacent main troughs 1 is not less than 200mm.

[0047] refer to Figure 1 and Figure 2 The conveyor belt 11 has slots 4 on its surface, which are opened along the width direction of the conveyor belt 11. Multiple slots 4 are opened, and adjacent slots 4 are spaced apart along the length direction of the conveyor belt 11. The upper part of the conveyor belt 11 is concave, and the concave part is located in the middle of the belt surface, that is, a V-shaped conveyor belt 11 is adopted. A sealing plate 5 is inserted and sealed at the end of the single main trough 1. The sealing plate 5 is located at the lower end of the single main trough 1 after it is inclined. The insertion direction is vertical. When the sealing plate 5 is fully inserted into the end of the main trough 1, the sealing plate 5 seals the end of the main trough 1.

[0048] refer to Figure 1 and Figure 2 The bottom of the main channel 1 is fixed with a main channel support leg 8. The main channel support leg 8 has its own length adjustment capability, that is, it can use a telescopic rod. A tripod 81 is fixed at the bottom of the main channel support leg 8, so that the main channel support leg 8 can adapt to uneven terrain.

[0049] refer to Figure 1 and Figure 2 A corrugated section 21 is provided between the support groove 2 and the main groove 1. One end of the corrugated section 21 is connected to the main groove 1, and the other end is connected to the support groove 2. The corrugated section 21 can be connected to the main groove 1 or the support groove 2 by bolts, which is simple to operate and convenient to assemble and disassemble. Since the corrugated section 21 has the property of expansion and contraction, it is used to adjust the position of the support groove 2 relative to the main groove 1 in the horizontal and vertical directions. A branch leg 7 is provided at the bottom of the support groove 2. The branch leg 7 includes an inner leg 71 and an outer leg 72. One end of the inner leg 71 is ball-jointed to the support groove 2, and the other end is inserted into the outer leg 72. A positioning bolt 73 is provided on the outer leg 72. Multiple bolt holes are opened on the outer leg 72, and adjacent bolt holes are spaced apart along the length of the outer leg 72. The positioning bolt 73 passes through the corresponding bolt hole and is threaded to the inner leg 71, thereby realizing the relative fixation of the positions of the inner leg 71 and the outer leg 72. The specific structure of the main groove support leg 8 can also be set to be the same as that of the branch leg 7, so as to realize the length extension and transformation of the main groove support leg 8 itself.

[0050] refer to Figure 2 A vibration motor 6 is fixed on the outer wall of the support groove 2. The vibration motor 6 is located at the bottom of the support groove 2 and at the end of the support groove 2 away from the main groove 1. The vibration motor 6 can accelerate the falling of concrete on the support groove 2. After the support groove 2 is erected on the main groove 1, the end of the support groove 2 away from the main groove 1 is inclined downward, which facilitates the sliding of concrete on the support groove 2.

[0051] The implementation principle of an electric chute for cast-in-place horizontal concrete structures according to an embodiment of this application is as follows: The chute is composed of a main chute 1 and branch chute 2, and concrete is transported by a conveyor belt 11. It can be hoisted by a tower crane to facilitate installation and disassembly. The specific installation position can be adjusted according to the actual needs of the site. By opening multiple diversion ports 12 on the main chute 1, the position of the branch chute 2 can be set. Due to the presence of corrugated sections 21, the position of the branch chute 2 can be adjusted relative to the main chute 1, not only in the horizontal direction but also in the vertical direction. This achieves the effect of facilitating high-speed pouring of concrete components in any area during long-distance concrete transportation. The high-speed transportation of concrete is achieved by the conveyor belt 11.
