Description

Technical Field

[0001] This utility model relates to the field of concrete structure technology, and in particular to a prefabricated concrete structure. Background Technology

[0002] Prefabricated concrete structures are a construction method that industrializes and standardizes traditional building processes. They involve prefabricating concrete components (such as beams, slabs, columns, and walls) in a factory, then transporting them to the construction site for reliable assembly. Compared to traditional cast-in-place concrete structures, prefabricated concrete structures offer numerous advantages. They significantly shorten the construction cycle because many components are prefabricated in the factory, requiring only assembly on-site, saving considerable time. Simultaneously, they reduce wet work on the construction site, lowering dust and noise pollution, making them more environmentally friendly.

[0003] A search revealed a Chinese utility model patent with patent number CN221399476U, which discloses a prefabricated concrete structure. Compared with existing technologies, this utility model patent with patent number CN221399476U, through the inclusion of protrusions, lower slots, reserved reinforcing bars, reinforcing bar holes, grouting holes, positioning holes, positioning columns, insertion holes, movable slots, gears, rack rods, internal hexagonal knobs, countersunk grooves, and through holes, enables multi-positioning combination assembly between the upper and lower walls.

[0004] After the upper and lower walls are assembled, the aforementioned device uses an internal hexagonal knob controlled through the through hole to extend the rack rod from the movable slot and insert it into the two side holes to achieve lateral positioning. Because the rack rod is set horizontally, in actual use, the internal hexagonal knob controls the rack rod to extend horizontally and insert into the two side holes to achieve lateral positioning. However, the horizontal setting of the rack rod makes it difficult to achieve effective longitudinal positioning on the plane. This may cause relative displacement between the walls when the structure is subjected to longitudinal forces (such as seismic forces, wind forces, etc.), affecting the stability and safety of the overall structure and increasing the risk of concrete cracking and damage. Therefore, in order to solve the above problems, a prefabricated concrete structure is proposed. Utility Model Content

[0005] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a prefabricated concrete structure.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A prefabricated concrete structure includes an upper wall and a lower wall. An assembly structure is provided between the upper wall and the lower wall. The assembly structure includes multiple positioning pins and positioning columns fixedly connected inside the lower wall. An assembly plate is installed at the bottom of the upper wall. The multiple positioning pins and positioning columns cooperate with each other with the assembly plate. Multiple transverse stress columns and longitudinal stress columns are movably connected between the upper wall and the lower wall.

[0008] The above technical solution further includes:

[0009] The assembly structure also includes: multiple supporting ribs are provided inside the upper wall, and the multiple supporting ribs and connecting plates are welded together as one unit, and the side of the connecting plate away from the upper wall is fixedly connected to the assembly plate.

[0010] Multiple lateral holes and longitudinal holes are provided through the locating pins and the assembly plate. A lateral stress column is slidably provided inside the lateral hole, and a longitudinal stress column is slidably provided inside the longitudinal hole.

[0011] The bottom of the assembly plate has multiple positioning grooves, and the positioning grooves and positioning pins slide relative to each other.

[0012] The bottom protrusion of the assembly plate is provided with a first buffer pad and a second buffer pad on both sides, and the first buffer pad and the second buffer pad slide relative to each other with the positioning pin. The bottom protrusion of the assembly plate is provided with a plurality of positioning holes, and the positioning holes slide relative to the positioning pin.

[0013] The positioning pin is threaded with a second fastening bolt and a first fastening bolt respectively. The first fastening bolt is located on the side of the first buffer pad near the connecting plate, and the second fastening bolt is located on the side of the second buffer pad near the lower wall.

[0014] A grouting hoop is provided between the upper wall and the lower wall. Grouting ports are symmetrically opened through the grouting hoop, and fixing bolts for locking are provided on the grouting hoop.

[0015] The multiple supporting ribs are cast integrally with the upper wall, and the multiple positioning pins and positioning columns are cast integrally with the lower wall.

[0016] This utility model has the following beneficial effects:

[0017] In this invention, the assembly structure enables omnidirectional lateral and longitudinal positioning between walls, effectively preventing relative displacement of the walls under stress. The design of lateral and longitudinal stress columns provides reliable stress support in both the lateral and longitudinal directions, thereby significantly improving the stability and safety of the overall structure.

[0018] In this invention, a reasonable assembly structure design can disperse stress and avoid stress concentration points in specific locations. By adopting a more uniform force distribution method, the risk of fatigue damage to concrete caused by stress concentration is reduced, and the service life of the structure is extended.

Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] Example

[0028] like Figures 1-5As shown, the present invention proposes a prefabricated concrete structure, including an upper wall 1 and a lower wall 2. An assembly structure is provided between the upper wall 1 and the lower wall 2. The assembly structure includes multiple positioning pins 7 and positioning columns 12 fixedly connected inside the lower wall 2. An assembly plate 9 is installed at the bottom of the upper wall 1. The multiple positioning pins 7 and positioning columns 12 cooperate with each other with the assembly plate 9. Multiple transverse stress columns 17 and longitudinal stress columns 18 are movably connected between the upper wall 1 and the lower wall 2.

[0029] An assembly plate 9 is installed at the bottom of the upper wall 1. During the assembly process, the positioning pins 7 and positioning posts 12 are inserted into the holes of the assembly plate 9 to achieve the initial positioning of the upper wall 1 and the lower wall 2. The multiple transverse stress posts 17 and longitudinal stress posts 18 set between the positioning posts 12 and the assembly plate 9 further enhance the positioning accuracy and stability between the upper wall 1 and the lower wall 2. The transverse stress posts 17 can transmit and disperse stress in the horizontal direction to prevent the wall from undergoing relative displacement under the action of horizontal force, and the longitudinal stress posts 18 can also transmit and disperse stress in the horizontal direction.

[0030] The assembly structure also includes: multiple support ribs 19 are provided inside the upper wall 1, and the multiple support ribs 19 and the connecting plate 5 are welded together. The side of the connecting plate 5 away from the upper wall 1 is fixedly connected to the assembly plate 9. Both the upper wall 1 and the lower wall 2 are provided with support ribs 19, which are used to support the casting of the upper wall 1 and the lower wall 2, forming an integral structural frame.

[0031] Multiple locating pins 7 and assembly plates 9 are connected by multiple transverse holes 13 and longitudinal holes 14. Transverse stress columns 17 are slidably arranged inside the transverse holes 13, and longitudinal stress columns 18 are slidably arranged inside the longitudinal holes 14. When the upper and lower walls are assembled, the multiple transverse stress columns 17 and longitudinal stress columns 18 are inserted into the transverse holes 13 and longitudinal holes 14 respectively, thereby enhancing the load-bearing capacity of the wall.

[0032] The bottom of the assembly plate 9 is provided with multiple positioning grooves 16, which slide relative to each other with the positioning pins 7; the bottom protrusion of the assembly plate 9 is provided with a first buffer pad 6 and a second buffer pad 8 on both sides, which slide relative to each other with the positioning pins 7; the bottom protrusion of the assembly plate 9 is provided with multiple positioning holes 15, which slide relative to each other with the positioning pins 7.

[0033] The positioning pin 7 is threaded with a second fastening bolt 10 and a first fastening bolt 11 respectively. The first fastening bolt 11 is located on the side of the first buffer pad 6 near the connecting plate 5, and the second fastening bolt 10 is located on the side of the second buffer pad 8 near the lower wall 2.

[0034] The positioning pin 7 is threaded with a second fastening bolt 10 and a first fastening bolt 11. The first fastening bolt 11 is located on the side of the first buffer pad 6 near the connecting plate 5 and is used to fasten the connection between the upper wall 1 and the assembly plate 9. The second fastening bolt 10 is located on the side of the second buffer pad 8 near the lower wall 2 and is used to fasten the connection between the lower wall 2 and the assembly plate 9.

[0035] A grouting hoop 3 is provided between the upper wall 1 and the lower wall 2. Grouting ports 4 are symmetrically opened through the grouting hoop 3. Fixing bolts for locking are provided on the grouting hoop 3.

[0036] After the upper and lower walls are properly fitted together, concrete is poured into the pouring hoop 3 through the grouting port 4, so that the upper wall 1 and the lower wall 2 form a whole at the pouring hoop 3, which enhances the connection strength. The pouring hoop 3 is equipped with fixing bolts for locking to ensure the stability of the pouring hoop 3 during the concrete pouring process. After the concrete at the connection point is dried, the contact between the pouring hoop 3 and the wall is released.

[0037] Multiple supporting ribs 19 are cast integrally with the upper wall 1, and multiple positioning pins 7 and positioning columns 12 are cast integrally with the lower wall 2, ensuring a firm connection between the positioning pins 7 and the lower wall 2. The positioning pins 7 not only transmit stress but also play a positioning role, ensuring the accurate relative position between the upper wall 1 and the lower wall 2.

[0038] In this embodiment, the upper wall 1 and the lower wall 2 are initially positioned and fixed by the positioning pin 7 and the positioning column 12; then, the stress between the walls is effectively transferred and dispersed by the synergistic effect of the transverse stress column 17 and the longitudinal stress column 18, thereby ensuring the stability and safety of the overall structure. Finally, the upper wall 1 and the lower wall 2 are formed into a whole by the set casting hoop 3.

[0039] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
