[0028] In order to make the purpose, technical solution and advantages of the embodiments of the present disclosure clearer, the technical solution of the embodiments of the present disclosure will be clearly and completely described below in conjunction with the drawings of the embodiments of the present disclosure. Obviously, the described embodiments are part of the embodiments of the present disclosure, not all of the embodiments. Based on the described embodiments of the present disclosure, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present disclosure.

[0029] See also Figure 1-7 A groove prefabricated wall panel provided by an embodiment of the utility model comprises two parallel and spaced plate bodies 1 and a first rib body 2 connected between the two plate bodies 1. The first rib body 2 divides the space between the two plate bodies 1 into a plurality of vertically penetrating holes 3. The inner walls of the holes 3 close to the horizontal ends of the plate bodies 1 are provided with a plurality of vertically spaced grooves 4. An annular rib 5 is slidably connected in the groove 4. A limiting component for limiting the movement of the annular rib 5 in the groove 4 is provided on the annular rib 5.

[0030] Specifically, the plate body 1 and the first rib body 2 are integrally formed by concrete, and the first rib body 2 extends up and down and is as long as the plate body 1; the cavity 3 is used for pouring concrete, and the corresponding side of the cavity 3 close to the side of the plate body 1 is open, and when the two wall panels are horizontally butted, the open cavities 3 on both sides can form a common cavity 3 closed on four sides; the groove 4 is horizontally opened on the inner wall of the plate body 1; one end of the groove 4 extends to the side of the plate body 1, that is, the annular rib 5 can slide from this end of the groove 4 to extend out of the plate body 1; the horizontal length of the annular rib 5 is not greater than the horizontal length of the groove 4, that is, the annular rib 5 can be pre-received in the groove 4; the limit assembly limits the free sliding of the annular rib 5 in the groove 4, and also limits the annular rib 5 to remain in a position extending out of the groove 4 by half the length. In actual use of the present technical solution, one wall panel is fixed in position, and the annular rib 5 is pre-installed in the groove 4 of the reserved horizontal connecting end. Then, another wall panel is horizontally spliced ​​close to the former and the groove 4 of the connecting end of the wall panel is left empty. After the connecting ends of the two wall panels are close, a distance is first maintained so that the cavities 3 correspond and the grooves 4 also correspond one by one. Then the annular rib 5 is pulled out from the corresponding groove 4 and crosses the gap between the two wall panels to initially enter the groove 4 of the other wall panel. After the annular rib 5 extends out of the groove 4 where it is pre-installed by half its length, the limiting component limits the position of the annular rib 5. Then the connecting ends of the two wall panels are close to each other again, so that the annular rib 5 is transitioned between the two grooves 4. Finally, concrete is poured into the cavity 3. After the concrete solidifies, the horizontal connection of the two wall panels can be achieved without relying on additional formwork.

[0031] Compared with the prior art, the groove prefabricated wall panel proposed in the embodiment of the utility model is provided with a hole 3. When the two wall panels are horizontally spliced, the holes 3 at the ends of the two wall panels are butted, and the corresponding grooves 4 correspond horizontally one by one. Therefore, the annular rib 5 pre-installed in the groove 4 on one side can be transitioned to the two grooves 4 by sliding, and then the annular rib 5 is limited by the limiting assembly to maintain the position. Finally, concrete is poured into the hole 3. After the concrete solidifies, the horizontal connection of the two wall panels can be achieved without relying on additional templates, thereby improving the assembly efficiency.

[0032] As a preferred technical solution of this embodiment, the annular rib 5 includes an embedding portion 51 embedded in parallel with the groove 4 and a positioning portion 52 connecting the embedding portion 51 to form a ring. Specifically, the annular rib 5 is approximately in the shape of a rectangular ring, with the long side being the embedding portion 51 and the short side being the positioning portion 52. The length of the positioning portion 52 matches the inner wall spacing of the two corresponding grooves 4 set on the inner walls of the two plate bodies 1.

[0033] As the preferred technical solution of this embodiment, the limiting assembly includes a sleeve 6 elastically and movably arranged on the positioning portion 52, a mark block 7 is fixedly arranged on the sleeve 6, and a positioning groove 8 matching the mark block 7 is arranged on the inner wall of the groove 4. Specifically, the sleeve 6 moves along the length direction of the positioning portion 52, and the mark block 7 is arranged on the outside at the same horizontal height as the annular rib 5. One end of the mark block 7 can slide in the groove 4, and this end of the mark block 7 is triangular or trapezoidal, and the positioning groove 8 matches the shape of the end of the mark block 7; when the annular rib 5 extends out of half the length of the groove 4, the mark block 7 corresponds to the positioning groove 8.

[0034] As a further preferred technical solution of this embodiment, a convex ring 9 is fixedly provided in the middle of the positioning portion 52, and two sleeves 6 are symmetrically provided with the convex ring 9 as the center, and an elastic member 10 is connected between the convex ring 9. Specifically, the setting of the elastic member 10 enables the sleeve 6 to remain elastically away from the convex ring 9, that is, the sleeve 6 drives the block 7 to keep extending into the groove 4, and causes the block 7 to abut against the inner wall of the groove 4, thereby generating static friction, which can hinder the free movement of the annular rib 5 in the groove 4, and facilitate the pre-loading of the annular rib 5 into the groove 4, and then the wall panel can be transported and moved; in addition, when the annular rib 5 extends out of half the length of the groove 4, the block 7 corresponds to the positioning groove 8. At this time, under the action of the elastic member 10, the sleeve 6 drives the end of the block 7 to remain embedded in the positioning groove 8 to limit the position of the annular rib 5 relative to the groove 4.

[0035] As a further preferred technical solution of this embodiment, the elastic member 10 is configured as a spring, and the spring is sleeved on the positioning portion 52. Specifically, the elastic member 10 is a spring, which can be sleeved on the positioning portion 52 to reduce the volume of the parts.

[0036] In another embodiment of the utility model, a clamping ring 11 is fixedly provided at one end of the mark block 7 away from the groove 4. When the mark block 7 corresponds to the positioning groove 8, the clamping rings 11 on the two mark blocks 7 can be concentric and inserted into the vertical connecting ribs. Specifically, the two clamping rings 11 on the same side of the annular rib 5 are staggered up and down; when the two wall panels are horizontally butt-jointed and the transition of half of each side of the annular rib 5 is in the grooves 4 on both sides, that is, the two groups of mark blocks 7 at both ends of the annular rib 5 correspond to the positioning grooves 8 and are embedded, so the two groups of clamping rings 11 are concentric. When the upper and lower layers of annular ribs 5 are correctly placed, the upper and lower groups of concentric clamping rings 11 also correspond vertically. Therefore, each group of clamping rings 11 is vertically inserted through the connecting ribs, thereby realizing the connection between the connecting ribs and the annular ribs 5, and further restricting the movement of the mark block 7, thereby restricting the stability of the annular rib 5 relative to the groove 4 or the wall panel, which is beneficial to the subsequent concrete pouring to form a stable steel skeleton structure.

[0037] As a preferred technical solution of the above embodiment, a plurality of second ribs 12 are fixedly provided on the inner wall of the cavity 3 close to the horizontal ends of the plate body 1, and are arranged alternately with the grooves 4. Specifically, the second ribs 12 are integrally formed with the concrete of the plate body 1; the intervals left by the upper and lower adjacent second ribs 12 are for the movement of the annular ribs 5, and the second ribs 12 can be used as lifting points to facilitate the lifting of the wall panels.

[0038] The above only describes some exemplary embodiments of the present invention by way of illustration. It is undoubted that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
