Description

Technical Field

[0001] The present application relates to the field of construction, and in particular to a segmented prefabricated assembly structure of an extra-long pier. Background Art

[0002] A pier is a lower load-bearing object used to support the upper structure in civil engineering. It plays an important role in projects such as bridges, overpasses, ramp bridges and flyovers.

[0003] However, the construction method of pier columns in the existing technology is still mainly cast in place. From pier column reinforcement binding, formwork installation, concrete pouring to maintenance, it takes at least ten days and requires a large number of formworks, which prolongs the construction period of the pier columns and thus increases the construction cost of the pier columns. Utility Model Content

[0004] In order to improve the problem of the construction period of the pier column, the present application provides a segmented prefabricated assembly structure of an ultra-long pier column.

[0005] This application provides a segmented prefabricated assembly structure for an ultra-long pier column, which adopts the following technical solution:

[0006] A segmented prefabricated assembly structure for an extra-long pier includes a plurality of prefabricated columns, one end of each prefabricated column is connected to a fixed block, the other end of each prefabricated column is provided with a fixed cavity for embedding the fixed block, a solidification flow channel is provided on the circumferential outer wall of the fixed block, when the fixed block is embedded in the fixed cavity, the solidification flow channel is connected to the fixed cavity, the inner wall of the fixed cavity is provided with a casting flow channel, and the casting flow channel is connected to the solidification flow channel.

[0007] By adopting the above technical solution, multiple prefabricated columns are transported to the construction site, and the multiple prefabricated columns are spliced in sequence. The fixed blocks on the prefabricated columns are embedded in the fixed cavity on the previous prefabricated column, and the circumferential outer wall of the fixed block is pressed against the inner wall of the fixed cavity to form a limit. At the same time, the solidification flow channel is connected to the fixed cavity, and concrete is injected into the solidification flow channel through the pouring flow channel. The concrete in the solidification flow channel is solidified and formed, thereby completing the assembly of two adjacent prefabricated columns. The multiple prefabricated columns are assembled and fixed in sequence, and the construction of the super-long pier is completed. There is no need to go through the steps of tying the pier reinforcement, installing the formwork, pouring concrete, and curing at the construction site, thereby shortening the construction period of the pier and reducing the construction cost of the pier.

[0008] Optionally, an exhaust flow channel is opened on the inner wall of the fixed cavity, and the exhaust flow channel is connected to the solidification flow channel.

[0009] By adopting the above technical solution, when concrete fills the solidification flow channel through the pouring flow channel, the concrete squeezes the air in the solidification flow channel and discharges it from the exhaust flow channel. After the concrete fills the solidification flow channel, it fills the inner cavity of the exhaust flow channel, allowing users to directly observe the concrete pouring situation in the solidification flow channel, thereby improving the assembly efficiency of adjacent prefabricated columns.

[0010] Optionally, the prefabricated column is connected to a pushing assembly, which includes a pushing plate. The fixed cavity is provided with a pushing cavity for the pushing plate to slide on the inner wall facing the solidification flow channel, and the pushing plate can compact the concrete in the solidification flow channel.

[0011] By adopting the above technical solution, when concrete fills the solidification flow channel through the pouring flow channel, the pushing plate is driven to slide along the inner wall of the pushing cavity toward the solidification flow channel, and the pushing plate squeezes the concrete in the solidification flow channel, driving the air between the concrete in the solidification flow channel to be discharged from the exhaust flow channel, thereby achieving compaction of the concrete in the solidification flow channel, making it difficult for bubbles to remain in the concrete in the solidification flow channel, thereby improving the connection strength between adjacent prefabricated columns.

[0012] Optionally, the pushing assembly also includes a handle, and a sliding cavity for the handle to slide is opened on the surface of the prefabricated column, and the sliding cavity is connected to the pushing cavity. One end of the handle is flush with the surface of the prefabricated column and closes the sliding cavity, and the other end of the handle is connected to the surface of the pushing plate, and the sliding direction of the handle and the sliding direction of the pushing plate are parallel to each other.

[0013] By adopting the above technical solution, one end of the handle is flush with the surface of the prefabricated column and closes the sliding cavity, and the other end of the handle is connected to the surface of the push plate. The handle provides a force point for the user. The user only needs to press the handle to drive the push plate to slide in the direction close to the solidification flow channel, thereby improving the compaction efficiency of the concrete in the solidification flow channel.

[0014] Optionally, the pushing assembly further comprises an elastic member 1, one end of the elastic member 1 in the elastic direction is connected to the inner wall of the sliding cavity, and the other end of the elastic member 1 in the elastic direction is connected to the handle surface, the elastic member 1 has an elastic force driving the handle to slide in the direction away from the sliding cavity, and the handle surface tends to be flush with the prefabricated column.

[0015] By adopting the above technical solution, when the user overcomes the elastic force of the elastic part and presses the handle to slide toward the pushing cavity, the pushing plate is driven to squeeze the solidified soil in the solidification flow channel. When the concrete in the solidification flow channel is compacted, the handle is released, the thrust on the handle disappears, and the elastic force of the elastic part drives the handle to slide in the direction away from the sliding cavity, and the surface of the handle is flush with the surface of the prefabricated column, realizing automatic resetting of the handle without the user having to manually drive the handle to slide, thereby improving the construction efficiency of the pier column.

[0016] Optionally, an air outlet is provided on the surface of the handle, and the air outlet is connected to the sliding cavity.

[0017] By adopting the above technical solution, the handle closes the sliding cavity. When the handle slides on the inner wall of the sliding cavity, the air pressure in the sliding cavity increases, the sliding cavity is connected to the air outlet, and the air in the sliding cavity is discharged through the air outlet, reducing the thrust of the handle sliding on the inner wall of the sliding cavity, thereby improving the construction efficiency of the pier column.

[0018] Optionally, a casting hole is opened on the surface of the handle, and the casting hole is connected to the sliding cavity.

[0019] By adopting the above technical solution, after the concrete in the solidification flow channel is compacted, the concrete is injected into the sliding cavity through the pouring hole, and at the same time, the air in the sliding cavity is driven to be discharged from the air outlet. After the concrete fills the sliding cavity, the concrete in the sliding cavity solidifies and is fixed, making it difficult for the handle to slide on the inner wall of the sliding cavity, thereby achieving the fixation of the handle on the prefabricated handle, thereby ensuring the structural strength of the pier column.

[0020] Optionally, the prefabricated column is connected to a positioning assembly, which includes a positioning column and an elastic member 2. The inner wall of the fixed cavity is provided with a positioning cavity for the positioning column to slide, and the sliding direction of the positioning column and the sliding direction of the push plate are parallel to each other. One end of the elastic member 2 in the elastic direction is connected to the inner wall of the positioning cavity, and the other end of the elastic member 2 in the elastic direction is connected to the surface of the positioning column. The elastic member 2 has the elastic force to drive the positioning column to slide in the direction away from the positioning cavity, and the end of the positioning column has a tendency to protrude from the inner wall of the fixed cavity, and the surface of the fixed block is provided with a positioning groove for the end of the positioning column to be embedded.

[0021] By adopting the above technical solution, when the fixed block is embedded in the fixed cavity, the positioning groove is connected to the positioning cavity, and the elastic force of the elastic member drives the positioning column to be embedded in the positioning groove. The circumferential outer wall of the positioning column presses against the inner wall of the positioning groove to form a limit, so that the fixed block is not easily offset on the inner wall of the fixed cavity, thereby improving the limit stability of the fixed block in the fixed cavity.

[0022] In summary, this application includes at least one of the following beneficial technical effects:

[0023] 1. The setting of fixing blocks and fixing cavities allows multiple prefabricated columns to be assembled and fixed in sequence, thus completing the construction of ultra-long piers. This eliminates the need for on-site steps such as pier reinforcement binding, formwork installation, concrete pouring, and maintenance. This shortens the construction period of the piers and reduces the construction cost.

[0024] 2. The exhaust channel is set up. Concrete is filled into the solidification channel first and then into the exhaust channel cavity. This allows the user to directly observe the concrete pouring status in the solidification channel, thereby improving the assembly efficiency of adjacent prefabricated columns.

[0025] 3. The setting of the push plate realizes the compaction of the concrete in the solidification flow channel, making it difficult for bubbles to remain in the concrete in the solidification flow channel, thereby improving the connection strength between adjacent prefabricated columns.

[0029] The following is combined with Figure 1-2 This application is described in further detail.

[0030] The embodiment of the present application discloses a segmented prefabricated assembly structure of an ultra-long pier. Figure 1 and Figure 2 The segmented prefabricated assembly structure of the super-long pier includes a plurality of prefabricated columns 1. A fixing block 2 is integrally formed and fixed at one end of the prefabricated column 1 in the length direction. A fixing cavity 11 for the fixing block 2 to be embedded is provided at the other end of the prefabricated column 1 in the length direction. A solidification flow channel 21 is provided on the circumferential outer wall of the fixing block 2. When the fixing block 2 is embedded in the fixing cavity 11, the solidification flow channel 21 is connected to the fixing cavity 11. A casting flow channel 12 is provided on the bottom wall of the fixing cavity 11. The casting flow channel 12 passes through the outer wall of the prefabricated column 1 in the depth direction and is connected to the solidification flow channel 21. When the prefabricated column 1 is placed on the upper surface of the prefabricated column 1 When the fixing block 2 is embedded in the fixing cavity 11 on the previous prefabricated column 1, the pouring flow channel 12 is connected to the fixing cavity 11. When the concrete is filled into the solidification flow channel 21 through the pouring flow channel 12, the concrete in the solidification flow channel 21 solidifies, and the assembly of two adjacent prefabricated columns 1 is completed. The above steps are continued to assemble multiple prefabricated columns 1 in sequence, and the construction of the super-long pier is completed. There is no need to go through the steps of tying the pier reinforcement, installing the formwork, pouring concrete and curing at the construction site, which shortens the construction period of the pier and thus reduces the construction cost of the pier.

[0031] Reference Figure 2An exhaust channel 13 is provided on the inner wall of the fixed cavity 11. The exhaust channel 13 penetrates the outer wall of the prefabricated column 1 and is connected to the solidification channel 21. When the concrete fills the solidification channel 21, the air in the solidification channel 21 is discharged from the exhaust channel 13, so that bubbles are not easily retained between the concrete in the solidification channel 21, thereby improving the structural strength of the two adjacent prefabricated columns 1. At the same time, the concrete filling the solidification channel 21 fills the exhaust channel 13, so that the staff can directly observe the filling status of the concrete in the solidification channel 21, thereby improving the construction efficiency of the prefabricated column 1.

[0032] Reference Figure 2 The prefabricated column 1 is equipped with a positioning assembly 3, which can initially limit the fixed block 2 to the fixed cavity 11. The positioning assembly 3 includes a positioning column 31 and an elastic member 32. The inner wall of the fixed cavity 11 is provided with a positioning cavity 14 for the sliding of the positioning column 31. The sliding direction of the positioning column 31 is parallel to the length direction of the prefabricated column 1. The elastic member 32 can be a compression spring or a tension spring. In the embodiment of the present application, the elastic member 32 is a compression spring with a certain deformation ability. One end of the elastic member 32 in the elastic direction is fixed to the inner wall of the positioning cavity 14, and the other end of the elastic member 32 in the elastic direction is fixed to the surface of the positioning column 31. The elastic member 32 has an elastic force that drives the positioning column 31 to slide in the direction away from the positioning cavity 14, and the end of the positioning column 31 tends to protrude from the inner wall of the fixed cavity 11.

[0033] Reference Figure 2 When the locking cam 31 is unlocked, the locking cam 31 is unlocked and the locking cam 31 is unlocked, so that the cam 31 can be unlocked when the locking cam 31 is unlocked.

[0034] Reference Figure 2The prefabricated column 1 is equipped with a pushing assembly 4, which can compact the concrete in the solidification flow channel 21. The number of pushing assemblies 4 can be one, two or more. In the embodiment of the present application, the number of pushing assemblies 4 is multiple, and multiple pushing assemblies 4 are connected to the outer peripheral surface of the prefabricated column 1 at intervals. The pushing assembly 4 includes a pushing plate 41, a handle 42 and an elastic member 43. The fixed cavity 11 is provided with a pushing cavity 15 for the pushing plate 41 to slide on the inner wall toward the solidification flow channel 21. The surface of the prefabricated column 1 is provided with a sliding cavity 16 for the handle 42 to slide. The sliding cavity 1 6 penetrates the outer wall of the prefabricated column 1 in the depth direction and is connected to the pushing cavity 15, and the end of the handle 42 is welded and fixed to the surface of the pushing plate 41; the elastic member 43 can be a compression spring or a tension spring. In the embodiment of the present application, the elastic member 43 is a compression spring with a certain deformation ability. One end of the elastic member 43 in the elastic direction is fixed to the inner wall of the sliding cavity 16, and the other end of the elastic member 43 in the elastic direction is fixed to the surface of the handle 42. The elastic member 43 has the elastic force to drive the handle 42 to slide in the direction away from the sliding cavity 16, and the surface of the handle 42 tends to be flush with the surface of the prefabricated column 1.

[0035] Reference Figure 2 When concrete fills the solidification channel 21 through the pouring channel 12, the staff overcomes the elastic force of the elastic member 43 and drives the handle 42 to slide toward the sliding cavity 16, driving the push plate 41 to squeeze the concrete in the solidification channel 21, driving the air in the concrete in the solidification channel 21 to be discharged from the exhaust channel 13, thereby compacting the concrete in the solidification channel 21, thereby improving the connection strength between adjacent prefabricated columns 1.

[0036] Reference Figure 2 The handle 42 is provided with air outlet holes 421 and casting holes 422 at intervals on its surface. The axis of the air outlet hole 421 and the axis of the casting hole 422 are parallel to each other, and the axis of the air outlet hole 421 and the sliding direction of the handle 42 are parallel to each other. The air outlet hole 421 passes through the outer wall of the handle 42 along its own axis and is connected to the sliding cavity 16. The casting hole 422 passes through the outer wall of the handle 42 along its own axis and is connected to the sliding cavity 16. When the concrete fills the sliding cavity 16 through the casting hole 422, the air in the sliding cavity 16 is discharged from the air outlet hole 421. After the concrete fills the sliding cavity 16 and solidifies, the handle 42 is not easily offset in the sliding cavity 16, thereby achieving the fixation of the handle 42 on the prefabricated column 1.

[0037] The implementation principle of the segmented prefabricated assembly structure of an ultra-long pier column in the embodiment of the present application is as follows: when the fixing block 2 on the prefabricated column 1 is embedded in the fixing cavity 11 of the next prefabricated column 1, the solidification flow channel 21 is connected to the fixing cavity 11, and the concrete is filled in the solidification flow channel 21 through the pouring flow channel 12. The air in the solidification flow channel 21 is discharged from the exhaust flow channel 13, so that it is not easy for bubbles to remain between the concrete in the solidification flow channel 21, thereby improving the structural strength of the two adjacent prefabricated columns 1. At the same time, the concrete filled in the solidification flow channel 21 fills the exhaust flow channel 13, so that the staff can directly observe the filling status of the concrete in the solidification flow channel 21, thereby improving the construction efficiency of the prefabricated column 1, repeating the above steps to assemble and fix multiple prefabricated columns 1 in turn, and completing the construction of the ultra-long pier column. There is no need to go through the steps of pier column steel bar binding, template installation, concrete pouring and maintenance at the construction site, shortening the construction period of the pier column, and thus reducing the construction cost of the pier column.

[0038] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
