Obviously, the described embodiments are part of the embodiments of the present invention, rather than all of the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0025] In the description of the present invention, it should be noted that the orientation or positional relationship indicated by terms such as "upper", "lower", etc. is based on the orientation or positional relationship shown in the accompanying drawings, and is only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and thus cannot be understood as a limitation to the present invention. In addition, the terms "first", "second", and "third" are only used for descriptive purposes and cannot be understood as indicating or implying relative importance.

[0026] This embodiment provides a prefabricated wall, as Figure 1 shown. The prefabricated wall includes: a precast column 1 and a precast wall panel 2.

[0027] As Figure 1 shown, at least one side of the precast column 1 is provided with a wall panel connection groove 11. Specifically, when the precast column 1 is located at the two edges of a wall, then one side of the precast column 1 is provided with a wall panel connection groove 11; when the precast column 1 is located in the middle of a wall (not at the two edges), then the opposite two sides of the precast column 1 are both provided with wall panel connection grooves 11 (Figure 1 and Figure 2All are shown in this case); when the precast column 1 is located at the intersection of two intersecting walls, wall panel connection grooves 11 are provided on three sides (the two walls intersect in a T shape) or four sides (the two walls intersect in a cross shape) of the precast column 1.

[0028] As Figure 2 As shown, the end of the precast wall panel 2 is embedded in the wall panel connection groove 11, and there is a first gap 11a between the end and the bottom of the wall panel connection groove 11; a plurality of connection holes 21 are provided in the end of the precast wall panel 2 embedded in the wall panel connection groove 11. The plurality of connection holes 21 all extend from inside the wall panel connection groove 11 to outside the wall panel connection groove 11, and the plurality of connection holes 21 are all communicated with the first gap 11a to form a grouting channel.

[0029] Specifically, there is a first gap 11a between the end of the precast wall panel 2 and the bottom of the wall panel connection groove 11, which means that the depth of the end of the precast wall panel 2 embedded in the wall panel connection groove 11 is less than the depth of the wall panel connection groove 11. For example, if the depth of the wall panel connection groove 11 is 100 mm, the depth of the end of the precast wall panel 2 embedded in the wall panel connection groove 11 can be 50 mm.

[0030] Specifically, if the precast wall panel 2 is a solid wall panel, the connection holes 21 can be formed by embedding a hole-forming mold at its end when preparing the precast wall panel 2; when the precast wall panel 2 is a lightweight hollow wall panel, that is, as Figure 4 shown, when there is a through hole 22 in the precast wall panel 2, a plugging material 23 can be provided at a preset position in the through hole 22, and the part of the through hole 22 from the hole opening to the plugging material 23 forms the connection hole 21. Specifically, the shape of the connection hole 21 can be square, circular, etc., which is not limited here.

[0031] In the prefabricated wall of the present application, by providing the wall panel connection groove 11 on the precast column 1, and setting the end of the precast wall panel 2 to be embedded in the wall panel connection groove 11, and there is a first gap 11a between the embedded end and the bottom of the wall panel connection groove 11, and then a plurality of connection holes 21 that extend from inside the wall panel connection groove 11 to outside the wall panel connection groove 11 and are communicated with the first gap 11a are provided in the embedded end, a grouting channel with the first gap 11a as the main part and a T-shaped structure formed at a plurality of connection holes 21 is formed between the precast column 1 and the precast wall panel 2, so that the precast column 1 and the precast wall panel 2 can be firmly connected through the grouting material in the grouting channel, and the internal parts of the precast column 1 and the precast wall panel 2 are connected in a bite manner through the grouting material injected into the T-shaped structure, further improving the stability of the connection between the precast column 1 and the precast wall panel 2, and further making the prefabricated wall have higher safety and stability.

[0032] In this application, in order to further improve the connection stability of the prefabricated wall, the width of the notch of the wall panel connection groove 11 can also be set to be greater than the width of the bottom of the wall panel connection groove 11, that is, there is a second gap 11b between the precast column 1 and the side wall surface of the precast wall panel 2 at the notch. The second gap 11b is a filling gap. Thus, when the precast column 1 is embedded in the wall panel connection groove 11, there is a second gap 11b that can be filled between the precast column 1 and the side wall surface of the precast wall panel 2 at the notch. The filling material in the second gap 11b can improve the connection stability of the entire prefabricated wall while improving the sealing of the grouting channel and preventing the leakage of grouting material from affecting the grouting effect. Specifically, the filling material in the second gap 11b can be set as slightly expanded fine aggregate concrete. Of course, other types of filling materials can also be set. In this application, the wall panel connection groove 11 can be set as a trapezoidal groove. More specifically, it can also be set as an isosceles trapezoidal groove.

[0033] In this application, in order to further improve the connection stability of the prefabricated wall, the connection hole 21 can also be set to extend outside the wall connection groove. Specifically, still taking the depth of the wall panel connection groove 11 as 100 mm and the depth of the end of the precast wall panel 2 embedded in the wall panel connection groove 11 as 50 mm as an example, the depth of the connection hole 21 can be set to be greater than 50 mm, such as 100 mm, 200 mm, etc.

[0034] In this application, the prefabricated wall can also include a precast fence base 3, and the precast fence base 3 and the precast column 1 can be connected through a grouting sleeve structure. Specifically, as Figure 3 shown, reinforcing bars 31 can be arranged in the precast fence base 3, and grouting sleeves 12 corresponding to the reinforcing bars 31 can be arranged at the bottom end of the precast column 1. When the precast column 1 is connected to the precast fence base 3, each reinforcing bar 31 is inserted into the corresponding grouting sleeve 12, and then after grouting and sealing at the bottom of the precast column 1, grouting is carried out in the grouting sleeve 12 to realize the connection between the precast column 1 and the precast fence base 3. At this time, the bottom end of the precast wall panel 2 and the precast fence base 3 can also be connected through a grouting sleeve structure.

[0035] In this application, the precast wall panel 2 and the precast fence base 3 can also be connected by screws arranged in the first threaded holes and the second threaded holes by setting a first threaded hole at the bottom end of the precast wall panel 2 and a second threaded hole corresponding to the first threaded hole on the precast fence base 3.

[0036] Obviously, the above embodiments are merely examples given for clear illustration and not limitations on the implementation manners. For those of ordinary skill in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to enumerate all implementation manners here. And the obvious changes or modifications derived therefrom still fall within the protection scope of the present invention.
