[0041] As shown in the description accompanying drawings Figures 1-6 The utility model provides a technical scheme: an assembled wall structure, the assembled wall is prefabricated structure, including a plurality of wallboard 1, positioning column 2 and positioning base 3.

[0042] In a preferred embodiment, as Figure 1 , Figure 2 and Figure 3As shown, the wallboard 1 is provided with locking strips 11 at both ends, which are engaged with locking slots 21 provided on both sides of the positioning column 2, so that the locking strips 11 are inserted into the locking slots 21 to form a locking structure, thereby ensuring the stability of the wallboard 1 and the positioning column 2 in geometry when they are connected. Meanwhile, a plurality of first through holes 13 are uniformly provided on the locking strips 11, which are used in cooperation with second through holes 23 provided on the positioning column 2. When the through bolts 5 are inserted through the first through holes 13 and the second through holes 23 at corresponding positions, the adjacent wallboard 1 and the positioning column 2 can be connected. This double insurance connection mode not only ensures the initial installation and positioning accuracy of the wallboard 1 and the positioning column 2, but also strengthens the overall structural strength through mechanical connection.

[0043] In a preferred embodiment, as shown in Figure 1 and Figure 2 The wall structure further comprises a top concrete connecting plate 4, which is provided at the upper end of the positioning column 2 and connected with the bolt hole 12 provided at the upper end of the locking strip 11 through the connecting bolt 6. Through the arrangement of the connecting plate 4, the locking strips 11 of two adjacent wallboards 1 can be connected during installation, thereby ensuring the integrity between the wallboard 1 and the positioning column 2 after installation, and also playing a shielding role to prevent rainwater from entering the wall through the connection gap between the locking strip 11 and the locking slot 2 during use, thereby affecting the quality of the wall.

[0044] In a preferred embodiment, as shown in Figure 1 and Figure 2As shown, the positioning base 3 comprises a concrete positioning base plate 31 and a positioning insert 32 embeddedly installed on the positioning base plate 31. Specifically, the positioning base plate 31 is a U-shaped plate-shaped concrete structure formed by pouring, and an arc-shaped accommodation groove 34 is arranged on the inner side of each side plate of the positioning base plate 31. The accommodation groove 34 is used in cooperation with the clamping block 22 arranged at the lower end of the positioning column 2. During installation, the accommodation groove 34 and the clamping block 22 are matched with each other to form a mortise and tenon type matching relationship. During the installation process, accurate positioning is achieved through arc surface guidance, and after the installation is completed, transverse limiting action is generated through the shape surface constraint. The positioning base plate 31 can guide the installation of the positioning column 2 during installation and limit the positioning column 2 after installation, thereby effectively ensuring the stability of the positioning column 2 after installation. The outer side of the side plates and the bottom plate of the positioning base plate 31 are provided with a plurality of embedded ribs 33. The embedded ribs 33 are used in cooperation with the wall base concrete to form mechanical engagement with the wall base concrete, thereby enhancing the anchoring performance of the positioning base plate 31 and the foundation structure. The positioning insert 32 is vertically embedded on the upper surface of the bottom plate of the positioning base plate 31 and is rigidly connected with the grouting sleeve 7 pre-set at the bottom of the positioning column 2 through the pressure grouting process. This combined connection mode not only ensures the perpendicularity control between the positioning column 2 and the positioning base plate 31, but also forms a continuous force transmission path through the grout anchor connection, thereby finally constructing a wall anchoring system with geometric positioning accuracy and structural integrity.

[0045] In a preferred embodiment, as shown in Figure 1 、 Figure 2 、 Figure 5 and Figure 6 , the grouting sleeve 7 is embedded in the inner side of the lower end of the positioning column 2, the upper end of the grouting sleeve 7 is threadedly connected with the main rib 24 in the positioning column 2, the lower end surface is flush with the bottom end surface of the positioning column 2 to realize accurate butt joint, and the grouting sleeve 7 is used in cooperation with the positioning insert 32 to form a matching connection system. During installation, the vertical force transmission path is formed through the axial insertion of the positioning insert 32 and the grouting sleeve 7. The grouting port 72 and the discharge port 73 pre-set on the outer wall of the grouting sleeve 7 both extend to the outer surface of the positioning column 2 and form an open type operation window, thereby facilitating the pressure grouting operation during on-site construction and ensuring that the grout can fully fill the internal cavity of the grouting sleeve 7 and effectively wrap the positioning insert 32. Finally, the reliable connection between the positioning column 2 and the positioning insert 32 is realized through the grout anchor connection process.

[0046] In a preferred embodiment, as shown in Figure 6As shown, the grouting port 72 and the discharge port 73 are both in communication with the internal pressure grouting cavity 74 of the grouting sleeve 7, and a plurality of annularly arranged flow limiting bosses 75 are arranged in the pressure grouting cavity 74. Through the arrangement of the flow limiting bosses 75, in the grouting process, the flow limiting bosses 75 can generate a progressive flow resistance effect on the grouting material, forcing the grouting material to form pressure accumulation in the annular cavity formed by adjacent bosses; at the same time, the pressure gradient drives the grouting material to generate a radial compaction effect, effectively eliminating the grouting cavity and improving the compaction degree of the grouting-steel bar interface; during grouting, the flow limiting bosses 75 control the flow path of the grouting material, ensuring that the grouting material and the surface of the positioning dowel 32 form a continuous force transmission interface. This construction measure not only guarantees the mechanical properties of the grout anchor connection, but also delays the penetration path of the corrosion medium through physical barriers, significantly improves the structural durability of the node connection, and finally ensures that the grouting sleeve 7 and the positioning dowel 32 form a reliable mechanical connection.

[0047] In a preferred embodiment, as shown in Figure 6 As shown, the lower end of the pressure grouting cavity 74 near the grouting port 72 is also provided with a rubber sealing element 71, which is used in cooperation with the positioning dowel 32 to tightly extrude the outside of the positioning dowel 32 after the positioning dowel 32 is installed, so as to prevent the mortar from flowing outwards through the installation gap of the positioning dowel 32 during the pressure grouting process.

[0048] The construction process of the assembly type wall structure of the utility model includes:

[0049] Firstly, in the process of wall base treatment, the positioning base 3 is poured into the wall base in a pre-buried and first-poured manner, and the position of the positioning base 3 can meet the installation of the wall panel 1; after the later-poured concrete solidifies, the positioning column 2 is hoisted on the upper side of the positioning base 3, and in the hoisting process, the positioning dowel 32 is inserted into the lower end of the grouting sleeve 7, and the lower end face of the positioning column 2 is controlled to tightly press on the inner side face of the bottom plate of the positioning base plate 31, then after the hoisting of the positioning column 2 is completed, the grouting port 72 is connected with the grouting hose for grouting, until the continuous discharge of the mortar at the discharge port 73, the grouting process is completed, and the grouting port 72 and the discharge port 73 are plugged; finally, after the mortar solidifies, the wall panel 1 is hoisted, and the adjacent wall panels 1 and the positioning column 2 are connected by using the through bolt 5 and the connecting plate 4, and the on-site installation of the assembly type wall is completed.

[0050] The above only describes the preferred embodiments of the utility model, and is not used to limit the protection scope of the utility model.
