Description

Technical Field

[0001] The invention relates to the technical field of building construction, and in particular to an adjustable pier structure. Background Art

[0002] With the construction of sports stadium facilities in my country, in order to meet the requirements of prefabrication and on-site aesthetics, more and more curved stands in sports stadiums are formed by prefabricated concrete stands assembled on curved sloping roof slabs. The use of prefabricated concrete stands on site reduces the difficulty of stand construction and greatly shortens the construction period. The clear water effect of prefabricated concrete stands also improves the overall forming effect of the stand area in the stadium.

[0003] At present, there are two main ways to connect the concrete prefabricated stand panels with the curved sloping roof slabs. The first is to use cast-in-place concrete to cast piers as the piers to top the prefabricated stand panels. However, this connection structure still uses conventional casting and formwork methods. Compared with prefabricated buildings, it has various problems such as low construction efficiency, insufficient environmental protection, and poor quality control. The second is to use steel beam embedded parts to connect and fix the concrete prefabricated stand panels. Specifically, pins are reserved on the main and secondary beams of the steel structure frame and the prefabricated stand panels. The pin connection realizes the combination and fixation of the main and secondary beams of the steel structure frame and the prefabricated stand panels. However, this connection structure has high requirements on the pin docking accuracy. The accumulated deviations caused by the on-site steel structure installation and the prefabricated stand panel installation can easily lead to subsequent inability to accurately position or step on empty space.

[0033] The following combination Figures 1 to 7 , describing embodiments of the present invention.

[0034] According to an embodiment of the present invention, an adjustable pier structure is provided, which is used to connect a curved sloping roof slab 100 and a prefabricated stand slab 200. The prefabricated stand slab 200 is provided in plurality, and the plurality of prefabricated stand slabs 200 are arranged in a horizontal direction. The first side of the bottom end of the prefabricated stand slab 200 is overlapped and fixed to the top end of the adjacent prefabricated stand slab 200 to form a stepped stand. The adjustable pier structure includes a connecting component and a pier column 300. The connecting component is arranged in the curved sloping roof slab 100. The pier column 300 is aligned one by one with the prefabricated stand slab 200. It should be set that the pier column 300 is set parallel to the vertical direction, the bottom end of the pier column 300 is welded and fixed to the connecting assembly, and a nut 310 is set at the top of the pier column 300. A reserved through hole 210 is set through the second side of the prefabricated stand plate 200 corresponding to the position of the nut 310. A bolt 320 is clearance-fitted in the reserved through hole 210. The bottom end of the bolt 320 extends to the outside of the reserved through hole 210 and is tightened to the nut 310. The outer wall of the bolt 320 and the surrounding wall of the reserved through hole 210 are filled with a concrete part 220.

[0035] The adjustable pier structure of this embodiment is provided with a pier column 300 corresponding to the position of the fulcrum of each prefabricated grandstand panel 200 (i.e., the second side of the bottom end of the prefabricated grandstand panel 200), and the bottom end of the pier column 300 can be directly welded and fixed to the connecting component to form a clear load transfer route, thereby realizing the stable connection of the prefabricated grandstand panel 200 to the curved sloping roof floor 100; at the same time, by assembling the bolt 320 in the reserved through hole 210 in a clearance fit manner, in the process of assembling the prefabricated grandstand panel 200 to the top end of the corresponding pier column 300, the bolt 320 can be adjusted in the reserved through hole 210 along the radial direction of the reserved through hole 210, thereby eliminating the accumulated deviation generated after the assembly and installation of multiple prefabricated grandstand panels 200, ensuring the positioning accuracy of the subsequent prefabricated grandstand panels 200, and thereby realizing the accurate and rapid installation of the prefabricated grandstand panels 200 and the curved sloping roof floor 100.

[0036] It should be noted that the pier columns 300, connecting components and prefabricated stand panels 200 are set up separately and transported to the site for assembly. The pier columns 300 can be independently prefabricated in a standardized manner in the factory. During the mass production process in the factory, advanced equipment and a strict quality control system are used to ensure that the dimensional accuracy, material properties, etc. of each pier column 300 meet high standards. The standardized design makes the pier columns 300 universal and interchangeable, reducing errors and uncertainties in on-site construction.

[0037] It should be noted that the pier columns 300 are mass-produced in the factory, and before being transported to the site for installation, the connecting components and the curved sloping roof slabs 100 are cast simultaneously, so that the connecting components are pre-buried in the curved sloping roof slabs 100, thereby reducing or eliminating the on-site technical downtime and helping to reduce the difficulty of construction technology.

[0038] It should be noted that after the bolt 320 is adjusted to the set position in the reserved through hole 210 along the radial direction of the reserved through hole 210, it is only necessary to inject slurry into the reserved through hole 210, and after the slurry solidifies into the concrete part 220, the two can be fixed to achieve quick installation.

[0039] It should be noted that, in this embodiment, the stepped stands are divided into a plurality of prefabricated stand panels 200, and the plurality of prefabricated stand panels 200 are arranged in sequence along the vertical direction, and the plurality of prefabricated stand panels 200 are overlapped end to end along the horizontal direction to achieve a "straight instead of curved" architectural effect. In addition, in the process of assembling the prefabricated stand panels 200 on the top of the corresponding pier columns 300, the bolts 320 can be adjusted in the reserved through holes 210 along the radial direction of the reserved through holes 210 to eliminate the installation deviation of replacing the curve with a straight line, thereby ensuring the positioning accuracy of the prefabricated stand panels 200, and thus achieving accurate and rapid installation of the prefabricated stand panels 200 and the curved sloping roof slabs 100.

[0040] It should be noted that, in this embodiment, the pier column 300 and the connecting assembly are separately set and fixed into one by welding. In the process of welding and fixing the pier column 300 and the connecting assembly, the fulcrum of the prefabricated stand panel 200 is used as a measurement reference, and the position of the pier column 300 relative to the connecting assembly is adjusted horizontally, and the welding position of the pier column 300 is accurately positioned, thereby eliminating the accumulated deviation generated after the assembly and installation of multiple prefabricated stand panels 200, ensuring the positioning accuracy of the prefabricated stand panels 200, and achieving the "straight instead of curved" architectural effect on the basis of accurate and rapid installation of the prefabricated stand panels 200 and the curved sloping roof floor 100.

[0041] It is understood that the first side and the second side mentioned in the text refer to the two opposite sides of the prefabricated viewing platform board 200 in the horizontal direction. For the convenience of description, this embodiment uses Figure 1The middle prefabricated viewing platform panel 200 is horizontally overlapped with one side of the adjacent prefabricated viewing platform panel 200 as a first side description.

[0042] like Figure 1 and Figure 2 As shown, in some embodiments, the connection assembly includes an embedded pad 410 and embedded steel bars 420, the number of the embedded pads 410 is the same as the number of the pier columns 300, the bottom end of the pier column 300 is connected to the top end surface of the embedded pad 410, and the top end surface of the embedded pad 410 is flush with the top end surface of the curved sloping roof slab 100; each end of the embedded pad 410 facing away from the pier column 300 is connected to the embedded steel bar 420. By setting the top surface of the embedded pad 410 flush with the top surface of the curved sloping roof floor 100, on the one hand, the vertical spacing between the embedded pads 410 and the corresponding prefabricated stand panels 200 is kept consistent, so that the height of each pier column 300 is kept consistent, which is conducive to reducing the difficulty of construction; on the other hand, it effectively avoids cracks in the concrete bonding surface between the embedded pad 410 and the curved sloping roof floor 100, thereby effectively avoiding subsequent leakage and facilitating waterproof node processing.

[0043] It should be noted that by connecting the embedded steel bar 420 to the end of the embedded pad 410 away from the pier column 300, the embedded steel bar 420 can be connected to the steel mesh of the curved sloping roof slab 100, so that in the process of synchronously pouring the connecting component and the curved sloping roof slab 100, the embedded pad 410 is not easy to be displaced, ensuring that the top surface of the embedded pad 410 is flush with the top surface of the curved sloping roof slab 100 after the pouring construction is completed, effectively avoiding the concave and convex phenomenon.

[0044] It should be noted that the embedded pad 410, embedded steel bars 420 and curved sloping roof slab 100 are separately arranged, and the embedded pad 410 can be independently prefabricated in a standardized manner in the factory. During the mass production process in the factory, advanced equipment and a strict quality control system are used to ensure that the dimensional accuracy, material properties, etc. of each embedded pad 410 meet high standards. The standardized design makes the embedded pad 410 universal and interchangeable, reducing errors and uncertainties in on-site construction.

[0045] It should be noted that before the connecting components and the curved sloping roof slab 100 are cast and constructed simultaneously, the fulcrum of the prefabricated stand slab 200 is used as the measurement reference, and the position of the embedded pad 410 relative to the curved sloping roof slab 100 is adjusted horizontally to accurately position the position of the embedded pad 410, eliminate the construction error of the curved sloping roof slab 100 (such as concrete vibration), and ensure the positioning accuracy of the prefabricated stand slab 200, thereby achieving the "straight instead of curved" architectural effect based on the accurate and rapid installation of the prefabricated stand slab 200 and the curved sloping roof slab 100.

[0046] It can be understood that, specifically, the embedded steel bars 420 and the embedded base plate 410 are connected by perforation plug welding, and the anchor points, quantity, and anchor length of the embedded steel bars 420 must meet the structural stress requirements.

[0047] In order to improve the connection strength between the pier column 300 and the embedded plate 410, as shown in FIG. Figure 2 and Figure 4 As shown, specifically, the bottom end of the pier column 300 is set as an inclined surface 340, and the inclined surface 340 is set parallel to the top surface of the embedded part pad 410.

[0048] Specifically, the top surface of the embedded component backing plate 410 is provided with a second anti-corrosion coating, so that the embedded component backing plate 410 has better weather resistance and extends the service life.

[0049] like Figure 2 As shown, specifically, the embedded steel bar 420 is arranged in an L-shape, with the first portion of the embedded steel bar 420 arranged parallel to the embedded base plate 410, and the second portion of the embedded steel bar 420 connected to the end of the embedded base plate 410 facing away from the pier column 300. This arrangement helps ensure that the embedded base plate 410 is not easily misaligned during the simultaneous casting of the connection assembly and the curved sloping roof slab 100, thereby ensuring that the top surface of the embedded base plate 410 is flush with the top surface of the curved sloping roof slab 100 after casting, effectively avoiding the phenomenon of concave and convex.

[0050] like Figure 2As shown, specifically, the vertical projection area of ​​the pier column 300 is smaller than the vertical projection area of ​​the embedded pad 410. This arrangement allows for extra space on the top surface of the embedded pad 410 for horizontal adjustment of the pier column 300 relative to it. This allows for the horizontal adjustment of the pier column 300 relative to the embedded pad 410 during welding and fixing of the pier column 300 to the embedded pad 410, using the fulcrum of the prefabricated viewing platform 200 as a measurement reference. This allows for precise positioning of the welding position of the pier column 300, eliminates accumulated installation deviations of the embedded pad 410, and ensures the positioning accuracy of the prefabricated viewing platform 200. This allows for the precise and rapid installation of the prefabricated viewing platform 200 and the curved sloping roof slab 100, thereby achieving a "straight instead of curved" architectural effect.

[0051] It can be understood that the horizontal adjustment here refers to the movement of the buttress column 300 in any direction on a horizontal plane perpendicular to the vertical direction.

[0052] like Figures 2 to 4 As shown, in some embodiments, the support column 300 is configured as a steel pipe column, and a steel plate 330 is welded to the top of the support column 300. Two nuts 310 are welded to the steel plate 330, and the two nuts 310 are arranged on opposite sides of the support column 300 along a first direction. This arrangement can, on the one hand, increase the number of connection nodes between the support column 300 and the prefabricated viewing platform panel 200, which is conducive to improving the stability of the connection. On the other hand, during the process of welding and fixing the nuts 310 to the steel plate 330, the position of the nuts 310 relative to the steel plate 330 can be horizontally adjusted using the fulcrum of the prefabricated viewing platform panel 200 as a measurement reference, accurately positioning the welding position of the nuts 310, eliminating the accumulated deviations generated after the assembly and installation of multiple prefabricated viewing platform panels 200, and ensuring the positioning accuracy of the prefabricated viewing platform panels 200. This achieves a "straight instead of curved" architectural effect based on the precise and rapid installation of the prefabricated viewing platform panels 200 and the curved sloping roof slab 100.

[0053] It can be understood that the cross-sectional area of ​​the steel plate 330 perpendicular to the vertical direction is larger than the cross-sectional area of ​​the pier column 300 perpendicular to the vertical direction.

[0054] It is understood that the first direction in the text refers to the width direction of the prefabricated viewing platform board 200. Figure 4 The first direction in FIG is described as the width direction of the prefabricated viewing platform panel 200 .

[0055] Specifically, the outer side wall of the buttress column 300 is provided with a first anti-corrosion coating, so that the buttress column 300 has better weather resistance and extends its service life.

[0056] like Figure 2 and Figure 3As shown, specifically, the outer wall of the prefabricated stand panel 200 is provided with a grouting port 230 connected to the reserved through hole 210, so as to facilitate pouring high-grade non-shrinkage cement-based grouting material into the reserved through hole 210, filling the gap between the reserved through hole 210 and the bolt 320, and improving the connection stability.

[0057] In some embodiments, a height adjustment component is provided between the pier column 300 and the prefabricated grandstand board 200, and the height adjustment component is sleeved outside the nut 310 and the bolt 320; by selecting height adjustment components of different height sizes to be filled between the pier column 300 and the prefabricated grandstand board 200, the height position of the prefabricated grandstand board 200 can be fine-tuned, thereby realizing the function of vertical adjustment of the prefabricated grandstand board 200.

[0058] It should be noted that the height adjustment component is sleeved on the nut 310 and the bolt 320 to limit the extreme position of the horizontal movement of the height adjustment component, effectively preventing the height adjustment component from falling out from between the pier column 300 and the prefabricated stand board 200.

[0059] Specifically, the height adjustment assembly includes a separately provided rubber support 510 and a plurality of rubber gaskets 520. The rubber support 510 is sleeved outside the nut 310 and the bolt 320, and the rubber gasket 520 is sleeved outside the bolt 320. The rubber gasket 520 is arranged between the rubber support 510 and the prefabricated stand panel 200. By providing the rubber support 510 and the rubber gasket 520 separately, a corresponding number of rubber gaskets 520 can be flexibly selected and stacked on top of the rubber support 510 according to the needs of on-site installation, thereby obtaining height adjustment assemblies of different heights and sizes, thereby realizing the function of vertically adjusting the prefabricated stand panel 200.

[0060] like Figure 6 As shown, in some embodiments, the connection assembly includes a plurality of connecting secondary beams 430, the number of the connecting secondary beams 430 is the same as the number of the pier columns 300, and the bottom ends of the pier columns 300 are connected to the top ends of the connecting secondary beams 430; the connecting secondary beams 430 provided with the curved sloping roof slab 100 are used as the installation basis to reduce the assembly process.

[0061] The connecting secondary beam 430 is arranged parallel to the second direction, which refers to the tangent direction of the top point of the portion of the curved sloping roof slab 100 that overlaps with the connecting secondary beam 430 along the thickness direction of the curved sloping roof slab 100 .

[0062] like Figure 7As shown, in some embodiments, the curved sloping roof slab 100 is provided with a main beam 110 at one end vertically away from the buttress column 300. The connecting assembly includes a plurality of leveling supports 440, the number of which is the same as the number of the buttress columns 300. The bottom ends of the leveling supports 440 are welded and fixed to the main beam 110. The leveling supports 440 have a horizontally arranged top surface, and the bottom ends of the buttress columns 300 are connected to the top surfaces of the leveling supports 440. With this arrangement, the straight cut facilitates welding and fixing the buttress columns 300 to the top surfaces of the leveling supports 440.

[0063] It should be noted that this embodiment can achieve all-round adjustment of horizontal and vertical adjustments, meeting the all-round adjustment of the bottom end of the pier column 300 and the curved sloping roof floor 100, and the top end of the pier column 300 and the prefabricated grandstand panel 200; the installation accuracy of the pier column 300 is controlled layer by layer, realizing the rapid assembly construction and green construction of the prefabricated grandstand panel 200.

[0064] Although the embodiments of the present invention have been described with reference to the accompanying drawings, those skilled in the art may make various modifications and variations without departing from the spirit and scope of the present invention, and such modifications and variations shall all fall within the scope defined by the present invention.
