Description

Technical Field

[0001] This utility model relates to the field of prefabricated component production technology, and in particular to a modular vertical traffic core. Background Technology

[0002] Currently, various prefabricated shear wall structure systems are only designed and constructed for "ordinary" wall panels in terms of vertical structure, and have not yet addressed elevator shafts and their prefabricated integration, which are more difficult to construct on-site. Some structural systems even present difficulties in constructing edge components, making the construction of cylindrical structures like elevator shafts even more challenging.

[0003] Researching the prefabricated integration of elevator shafts and forming modular products can further reduce on-site construction difficulties, expand the application scope of prefabricated construction, and achieve "large-scale integration" in buildings. The longitudinally ribbed composite shear wall system has extensive construction experience in high-rise projects, providing a solid foundation and experience for the research on prefabricated integration of elevator shafts.

[0004] Therefore, how to provide a modular vertical traffic core that can reduce the difficulty of integrated construction while ensuring the smooth production of existing equipment, and whose doorway location should not affect production and installation, while meeting structural and construction specifications, is a technical problem that needs to be solved in this field.

[0005] Therefore, this utility model is proposed. Utility Model Content

Detailed Implementation

[0041] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present application, and not all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative effort should fall within the scope of protection of the present application.

[0042] Combination Figure 1-11This utility model provides a modular vertical traffic core, including a cylindrical structure 1 for accommodating a building's elevator. This cylindrical structure 1 can be either a single-door or double-door structure. The cylindrical structure 1 is formed by assembling multiple prefabricated components 2, with at least one prefabricated component having an elevator door 12. In a single-door structure, the elevator door is located on one of the prefabricated components; in a double-door structure, elevator doors can be located on two opposite prefabricated components. Each prefabricated component has edge cavities 3 on both sides. The edge cavities 3 between adjacent prefabricated components 2 correspond to each other and are assembled into a horizontally connected cast-in-place zone 4. Horizontal connecting reinforcing bars and vertical connecting reinforcing bars are arranged within the horizontally connected cast-in-place zone 4.

[0043] In this embodiment, there are four prefabricated components, each of which is a corner-type prefabricated component with a corner, or it can be called an L-shaped prefabricated component. The corner part of the component constitutes the corner part of the cylindrical structure 1.

[0044] The horizontal connecting reinforcement within the cast-in-place zone 4 includes horizontal reinforcing bars 5 extending from the edge of the precast component, and horizontal stirrups 6 disposed within the cast-in-place zone 4. The side ends of the horizontal reinforcing bars 5 extending from the edge of the precast component are closed structures, forming ring reinforcement to enhance the bond strength between the old and new concrete. The horizontal stirrups 6 extend from the edge cavity 3 on one side to the edge cavity 3 on the other side, further enhancing the connection strength of the cast-in-place zone.

[0045] The vertical connecting reinforcement includes straight reinforcement 7 or ring reinforcement with at least one closed structure at both ends. In this embodiment, it is a vertical ring reinforcement 8 with neither end being ring-shaped.

[0046] The straight reinforcing bars include a first straight reinforcing bar 9 located inside the horizontal stirrups 6 and a second straight reinforcing bar 10 located inside the horizontal reinforcing bars 5 extending from the edge of the precast component. The two straight reinforcing bars are respectively located on the side closer to the edge cavity 3 and the side closer to the center of the cast-in-place area, resulting in better vertical connection strength.

[0047] The ends of the straight reinforcing bars have threaded connections 11, which can be used when connecting vertical traffic cores on the upper and lower sides. Alternatively, for annular vertical reinforcing bars, the lower layer of vertical annular reinforcing bars can extend into the upper layer of cast-in-place area and overlap with the bottom of the upper layer of vertical annular reinforcing bars to enhance the vertical connection strength.

[0048] In some embodiments, at least one of the upper and lower ends of the annular reinforcing bar is a closed structure and is disposed inside the horizontal stirrup 6.

[0049] In some embodiments, the front and rear sides of the edge cavity 3 are respectively a longer long wing 31 and a shorter short wing 32, or the front and rear sides of the edge cavity have a wing 33 on only one side.

[0050] Furthermore, combined Figure 12-17 This paper introduces the vertical connection structures that can be used when connecting the upper and lower vertical traffic cores.

[0051] The traffic cores described above, including the upper traffic core 15 and the lower traffic core 16, have identical structures. The traffic cores further include a connecting structure linking the upper traffic core 15 and the lower traffic core 16, specifically:

[0052] In this embodiment, the upper traffic core 15 and the lower traffic core 16 are connected by a first connection structure, a second connection structure, or a third connection structure:

[0053] The first connection structure includes: the vertical connecting reinforcement of the upper traffic core 15 is a straight steel bar 7, and its bottom is connected to the top of the vertical connecting reinforcement (also a straight steel bar 7) of the lower traffic core 16 through a threaded connection part 11; the horizontal connecting cast-in-place area 4 of the upper traffic core 15 includes an upper section 13 and a lower section 14. The upper section 13 is a pre-cast concrete body, and the lower section 14 is a reserved cast-in-place area. With this connection structure, the upper section 13 can be pre-cast in the factory, making the traffic core a whole that is easy to transport to the construction site. When connecting the upper and lower traffic cores on site, only grouting is needed in the lower section 14 to achieve the connection, improving on-site construction efficiency. This connection method is particularly suitable when there are practical constraints, such as a large slope of the transport road, a narrow site, or a small lifting capacity of the tower crane, and when the modular vertical traffic core needs to be integrated on site, the vertical connecting reinforcement of the post-cast area is connected in the form of straight threads.

[0054] The second connection structure includes: the vertical connecting reinforcement of the upper traffic core 15 is straight steel bar 7, and its bottom is directly butt-joined with the top of the vertical connecting reinforcement (also straight steel bar 7) of the lower traffic core 16, or not connected; the horizontal connecting cast-in-place zone 4 of the upper traffic core 15 is pre-cast concrete from top to bottom. This is particularly suitable when the modular vertical traffic core is used in low-rise and multi-story structures, where the vertical reinforcement of the post-cast zone is designed as structural reinforcement and does not need to be connected.

[0055] The third connection structure includes: the vertical connecting reinforcement of the upper traffic core 15 is a closed ring (i.e., vertical ring reinforcement 8), and the top of the vertical connecting reinforcement of the lower traffic core 16 is also a closed ring (i.e., vertical ring reinforcement 8); the horizontal connection cast-in-place area 4 of the upper traffic core 15 includes an upper section 13 and a lower section 14, the upper section 13 is a pre-cast concrete body, and the lower section 14 is a reserved cast-in-place area; the top of the vertical connecting reinforcement of the lower traffic core 16 extends into the reserved cast-in-place area at the bottom of the upper traffic core 15 and overlaps with the bottom of the vertical connecting reinforcement of the upper traffic core 15. Similar to the first connection structure, this connection structure allows the upper section 13 to be pre-cast in the factory, making the traffic core a single unit for easy transport to the construction site. When connecting the upper and lower traffic cores on site, only grouting in the lower section 14 is needed to achieve the connection, improving on-site construction efficiency. Furthermore, the use of ring overlaps for the connection of the cast-in-place areas in both the upper and lower traffic cores enhances the anchorage strength of the cast-in-place areas.

[0056] The above description is only a preferred embodiment of this application. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of this application, and these improvements and modifications should also be considered within the scope of protection of this application.
