Description

Technical Field

[0001] This utility model relates to a prefabricated concrete wall for building construction, belonging to the field of prefabricated building technology. Background Technology

[0002] Precast concrete walls refer to wall structures made by manufacturing precast concrete components in a factory and then assembling and fixing them on the construction site. These wall structures are mainly composed of precast concrete components and are assembled and installed on site using reliable connection methods.

[0003] An existing patent (CN112922170B) describes a prefabricated concrete wall structure. In this device, after the wall panels are vertically inserted into the grooves on each set of bases, the bases support each set of wall panels. The bases significantly reduce ground settlement of each set of wall panels. Two sets of bases at the corners are vertically positioned, and the pre-embedded reinforcing bars inside adjacent sets of wall panels are connected and fixed to the uprights. This arrangement further connects adjacent sets of wall panels. The reinforcing bars on both sides of the wall panels are connected via the uprights. However, existing prefabricated wall panels require a concrete foundation for bottom support before installation, whereas this device… Although the base set in the middle is similar to a cast-in-place foundation, it cannot achieve a stable connection with the ground, thus reducing the overall stability of the building. Furthermore, there is no bottom concrete wall, and the vertical wall panels are directly connected to the ground, which cannot guarantee the connection stability between the subsequently poured ground concrete and the prefabricated concrete slab. Although the columns set in this device can connect adjacent walls, the connection method of relying solely on steel bars to the columns is not stable enough. There is no top-level connection structure at the top of the wall panels, and it is impossible to perform corresponding top-level connection treatment according to whether additional floors are added, so the concrete walls cannot be properly spliced. Utility Model Content

[0004] The purpose of this utility model is to provide a prefabricated concrete wall for building construction to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A prefabricated concrete wall for building construction includes a ground surface, a cast-in-place foundation, and foundation reinforcement. The cast-in-place foundation is located on the inner side of the ground surface. A bottom positioning post is located at the upper end of the cast-in-place foundation. A bottom concrete slab is located on the outer side of the lower end of the bottom positioning post. A side wall plate is located on the outer side of the upper end of the bottom concrete slab. A locking threaded post is located on the inner side of the lower side of the side wall plate. A hexagonal threaded sleeve is spirally connected to the outer side of the locking threaded post. Both the locking threaded post and the hexagonal threaded sleeve are slidably connected to the bottom positioning post. A top positioning post one is located at the upper end of the side wall plate. A top concrete slab is located on the outer side of the upper end of the top positioning post one. A top positioning post two is located at the right rear end of the top concrete slab.

[0007] Furthermore, the foundation is internally fixedly connected with foundation steel bars, the lower end of the foundation is fixedly connected with a pre-embedded metal plate, the upper end of the pre-embedded metal plate is fixedly connected with a pre-embedded positioning column, and the pre-embedded positioning column is rotatably connected to the bottom positioning column.

[0008] Furthermore, locking holes are provided on the inner upper end of the bottom positioning post, the inner lower end of the top positioning post one, and the inner upper and lower ends of the top positioning post two. Locking blocks are fixedly connected to the front and rear sides of the lower end of the bottom positioning post, the front and rear sides of the upper end of the top positioning post one, and the front and rear sides of the middle of the top positioning post two.

[0009] Furthermore, positioning holes are provided at the edges of both the bottom and top concrete slabs, and a limiting slot is provided at the middle of the positioning hole, the position of which corresponds to the position of the locking block.

[0010] Furthermore, a corner base column is fixedly connected to the upper corner of the bottom concrete slab, and a splicing protrusion is fixedly connected to the outer side of the corner base column. The splicing protrusion is fitted and connected to the side wall panel, and a splicing slot is provided on the side end face of the side wall panel.

[0011] Furthermore, an adjustment slot is provided on the upper end face of the top positioning post.

[0012] Furthermore, the locking threaded post and the hexagonal threaded sleeve are arranged at equal intervals. The locking threaded post and the hexagonal threaded sleeve located on the upper side are slidably connected to the side wall plate, the top positioning post one and the top positioning post two, respectively. The locking threaded post and the hexagonal threaded sleeve located on the side longitudinal direction are slidably connected to the side wall plate and the splicing protrusion plate, respectively.

[0013] The beneficial effects of this utility model are:

[0014] This invention utilizes pre-embedded metal plates and positioning columns to pre-cast concrete into the foundation, allowing the bottom positioning columns to protrude from the foundation. After the bottom concrete slab is secured to the outside of the positioning column, rotating the column causes the locking block on its outer side to engage in the limiting groove, thus fixing the bottom concrete slab in place. The side wall panel is then fitted onto the outside of the bottom positioning column and connected via a locking threaded post and a hexagonal threaded sleeve passing through the locking hole on the inside of the bottom positioning column. This ensures a stable connection between the bottom positioning column and the side wall panel, achieving mutual locking of the foundation, bottom concrete slab, and side wall panel, making the installation of prefabricated concrete buildings more secure. This invention utilizes the function of corner base columns to... It can be pre-cast on the foundation, and the side wall panels can be limited by splicing protruding plates. It is reinforced by hexagonal threaded sleeves and locking threaded posts. When it is necessary to assemble the top concrete slab, firstly, insert the top positioning post one into the preset hole groove at the upper end of the side wall panel, and then clamp the top concrete slab on the outside of the top positioning post one. Then, by inserting a flathead screwdriver into the adjustment slot and rotating it, the locking block on the outside of the top positioning post one can be locked in the limiting groove on the inside of the top concrete slab, so as to achieve a stable connection between the top concrete slab and the side wall panel. When it is necessary to build multiple layers, simply replace the top positioning post one with the second top positioning post. This makes the assembly of prefabricated concrete buildings more convenient and firm, and allows for splicing and use of different combinations. Attached Figure Description

Locking holes 14 are also provided on the front and rear lower ends of the bottom positioning post 3, the front and rear upper ends of the top positioning post 1 8, and the middle of the top positioning post 2 10. Locking blocks 15 are fixedly connected to both the front and rear sides. Positioning holes 16 are provided at the edges of the bottom concrete slab 4 and the top concrete slab 9. A limiting groove 17 is provided in the middle of the positioning hole 16, and the position of the limiting groove 17 corresponds to the position of the locking block 15. By setting up the pre-embedded metal plate 12 and pre-embedded positioning post 13, it can be pre-cast inside the poured foundation 2, and the bottom positioning post 3 can protrude from the poured foundation 2. After the bottom concrete slab 4 is clamped on the outside of the positioning post, the bottom positioning post 3 is... The rotation allows the locking block 15 on the outside of the bottom positioning post 3 to engage in the limiting slot 17, thus limiting and fixing the bottom concrete slab 4. The side wall plate 5 is then fitted onto the outside of the bottom positioning post 3 and connected through the locking threaded post 6 and the hexagonal threaded sleeve 7 passing through the locking hole 14 on the inside of the bottom positioning post 3. This allows the bottom positioning post 3 to be stably connected to the side wall plate 5, achieving mutual locking of the poured foundation 2, the bottom concrete slab 4, and the side wall plate 5, making the installation of the prefabricated concrete building more secure.

[0024] Please refer to Example 2 Figure 1 , Figure 3 and Figure 4The difference between this embodiment and Embodiment 1 is as follows: A top positioning post 8 is provided at the upper end of the side wall panel 5; a top concrete slab 9 is provided on the outer side of the upper end of the top positioning post 8; a second top positioning post 10 is provided at the right rear end of the top concrete slab 9; a corner base post 18 is fixedly connected at the upper corner of the bottom concrete slab 4; a splicing protrusion 19 is fixedly connected to the outer side of the corner base post 18; the splicing protrusion 19 is fitted and connected to the side wall panel 5; a splicing slot is provided on the side end face of the side wall panel 5; an adjustment slot 20 is provided on the upper end face of the top positioning post 8; locking threaded posts 6 and hexagonal threaded sleeves 7 are equally spaced; the locking threaded posts 6 and hexagonal threaded sleeves located on the upper side are slidably connected to the side wall panel 5, the top positioning post 8, and the second top positioning post 10, respectively; the locking threaded posts 6 and hexagonal threaded sleeves 7 located on the longitudinal side are slidably connected to the side wall panel 5 and the splicing protrusion 19, respectively. The dynamic connection utilizes the corner base column 18 to pre-cast onto the foundation 2, and the splicing protrusion plate 19 can limit the side wall panel 5.

When it is necessary to assemble the top concrete slab 9, firstly, the top positioning column 18 is inserted into the preset hole groove at the upper end of the side wall panel 5, and the top concrete slab 9 is clamped on the outside of the top positioning column 18. Then, by inserting a flathead screwdriver into the adjustment slot 20 and rotating it, the locking block 15 on the outside of the top positioning column 18 can be locked in the limiting slot 17 on the inside of the top concrete slab 9, so as to achieve a stable connection between the top concrete slab 9 and the side wall panel 5. When it is necessary to build multiple layers, simply replace the top positioning column 18 with the top positioning column 20. This makes the assembly of prefabricated concrete buildings more convenient and firm, and enables splicing and use of different combinations.

[0025] The working principle of this utility model is as follows: When in use, the pre-embedded metal plate 12 and pre-embedded positioning post 13 are pre-cast inside the foundation 2, allowing the bottom positioning post 3 to protrude from the foundation 2. After the bottom concrete slab 4 is secured to the outside of the positioning post, the bottom positioning post 3 is rotated, causing the locking block 15 on the outside of the bottom positioning post 3 to engage in the limiting slot 17, thus fixing the bottom concrete slab 4. The side wall plate 5 is then fitted onto the outside of the bottom positioning post 3, and connected via a locking threaded post 6 and a hexagonal threaded sleeve 7 passing through the locking hole 14 on the inside of the bottom positioning post 3. This ensures a stable connection between the bottom positioning post 3 and the side wall plate 5, achieving mutual locking of the foundation 2, the bottom concrete slab 4, and the side wall plate 5. This makes the installation of prefabricated concrete buildings more secure and utilizes the corner base... The function of column 18 is to precast it on the foundation 2, and to limit the side wall panel 5 through splicing protrusion plate 19. It is reinforced by hexagonal threaded sleeve 7 and locking threaded column 6. When it is necessary to assemble the top concrete slab 9, firstly, insert the top positioning column 18 into the preset hole groove at the upper end of the side wall panel 5, and then clamp the top concrete slab 9 on the outside of the top positioning column 18. Then, by inserting a flathead screwdriver into the adjusting slot 20 and rotating it, the locking block 15 on the outside of the top positioning column 18 can be locked in the limiting slot 17 on the inside of the top concrete slab 9, so as to achieve a stable connection between the top concrete slab 9 and the side wall panel 5. When it is necessary to build multiple layers, simply replace the top positioning column 18 with the top positioning column 20, making the assembly of prefabricated concrete buildings more convenient and firm, and enabling splicing and use of different combinations.
