[0020] Prefabricated construction is a construction method in which prefabricated components are manufactured in a factory and assembled on the construction site. Its standardized and efficient manufacturing characteristics give it the advantages of high efficiency and high quality. Existing prefabricated walls are generally composed of three parts: the wall body, the top beam of the wall body, and the ground beam. The top beam and the ground beam are often installed separately at the top and bottom of the wall body, and there is often no connection between the top beam and the ground beam. Therefore, the overall integrity of the prefabricated wall is not strong enough, and it cannot form a complete load-bearing system. As a result, the overall structural strength of existing prefabricated walls is not high enough.

[0021] See Figures 1 to 8 This invention provides a prefabricated wall.

[0022] The prefabricated wall includes a wall body 100, a ground beam 200, and a top beam 300. The wall body 100 has an internal cavity 101 containing ribs 400. The wall body 100 also contains reinforcing bars 500, one end of which extends to the top of the wall body 100, and the other end extends to the bottom. The ground beam 200 is positioned at the bottom of the wall body 100 and has multiple first reinforcing bar holes 201. The insertion holes 201 are arranged at intervals along the extension direction of the ground beam 200. The end of the insertion bar 500 extending to the bottom of the wall 100 is inserted into the first insertion hole 201 for fixation. The top beam 300 is used to be installed on the top of the wall 100. The top beam 300 is provided with a plurality of second insertion holes 301. Each second insertion hole 301 is arranged at intervals along the extension direction of the top beam 300. The end of the insertion bar 500 extending to the top of the wall 100 is inserted into the second insertion hole 301 for fixation.

[0023] In this type of prefabricated wall, the top beam 300 and the ground beam 200 are connected to each other by reinforcing bars 500 inserted in the wall 100. Therefore, the top beam 300 and the ground beam 200 are not installed separately at the top and bottom of the wall 100, but are pulled together by reinforcing bars 500. As a result, the overall integrity of the prefabricated wall is better and the overall structural strength of the prefabricated wall is also higher.

[0024] Wall 100 is a hollow structure printed by a 3D printing device. Rib 400 is also printed at the same time as wall 100.

[0025] Among them, the rib plate 400 bends and extends along the length of the wall 100 to form a support structure inside the wall 100, thereby strengthening the structural strength of the wall 100.

[0026] In some embodiments, along the length of the wall 100, the rib 400 extends from one end of the wall 100 to the other end in a wave-like structure, with the crests and troughs of the rib 400 connected to the inner wall of the wall 100, and the rib 400 being at the same height as the wall 100.

[0027] In some embodiments, the top beam 300 is a channel steel structure. The clear dimension of the bottom of the channel of the top beam 300 is larger than the width of the wall 100, so that the top beam 300 can be smoothly installed on the top of the wall 100.

[0028] The ground beam 200 is located at the bottom of the wall 100. The ground beam 200 is provided with a plurality of first reinforcing bar holes 201. Each first reinforcing bar hole 201 is arranged at intervals along the extension direction of the ground beam 200. Each first reinforcing bar hole 201 is set in correspondence with each second reinforcing bar hole 301.

[0029] The bottom of the top beam 300 is provided with multiple second insertion holes 301. Each second insertion hole 301 is arranged at intervals along the extension direction of the top beam 300. A insertion bar 500 is inserted through the middle of each wave of the rib plate 400. One end of the insertion bar 500 inserted inside the wall 100 is inserted into the second insertion hole 301 of the top beam 300 and then fixed by a fastening nut. The other end of the insertion bar 500 is inserted into the first insertion hole 201 of the ground beam 200 and fixed.

[0030] In some embodiments, the top beam 300 is provided with a plurality of observation holes 304, and the observation holes 304 are arranged at intervals along the extension direction of the top beam 300. The observation holes 304 are arranged alternately with the second insertion holes 301. When the top beam 300 is installed on the top of the wall 100, the observation holes 304 are used to observe the insertion of the reinforcing bar 500 into the second insertion hole 301, and the alignment of the centerline of the top beam 300 with the centerline of the top of the wall 100.

[0031] To ensure the stability of the reinforcing bar 500 inside the wall 100, in some embodiments, a positioning device 600 is provided in the cavity 101. The positioning device 600 is installed on the reinforcing bar 500. The end of the positioning device 600 is an arc-shaped structure. The positioning device 600 can rotate relative to the reinforcing bar 500. One end of the positioning device 600 is used to press against the rib plate 400, and the other end of the positioning device 600 is used to press against the inner wall of the wall 100.

[0032] Specifically, the positioning device 600 is located in the middle of the interior of the wall 100. The positioning device 600 includes a base plate 610, a first side plate 620, and a second side plate 630. A through hole 611 for inserting the reinforcing bar 500 is opened in the middle of the base plate 610. The first side plate 620 and the second side plate 630 are both fixed to both ends of the base plate 610 and located on the same side of the base plate 610. Both the first side plate 620 and the second side plate 630 are set as an outwardly arched arc structure. During installation, the wall 100... Each waveform inside the 0 is provided with a positioning device 600 in the middle. The insert 500 passes through the through hole 611 of the positioning device 600. The arched side of the first side plate 620 abuts against the inner wall of the wall 100, and the arched side of the second side plate 630 abuts against the crest or trough of the rib plate 400. Thus, the positioning device 600 fixes the insert 500. The arched arc structure makes it easy to rotate the positioning device 600 to abut against the crest or trough of the rib plate 400.

[0033] It should be noted that the shape of the second side plate 630, which is used to abut against the crests and troughs of the rib plate 400, is set to an arched shape that can adapt to the crests and troughs.

[0034] In some other embodiments, the positioning device 600 may also be provided with chamfered triangular structures on both sides of the base plate 610, and the positioning device 600 is fixed between the rib plate 400 and the inner wall of the wall 100 by the chamfered triangular structures.

[0035] In some embodiments, a membrane bag 700 is provided on the inner side of the wing plate 303 of the top beam 300, and a grouting hole 302 corresponding to the membrane bag 700 is provided on the wing plate 303, and the grouting hole 302 communicates with the membrane bag 700.

[0036] Specifically, multiple membrane bags 700 are provided between the inner side of the flange 303 of the top beam 300 and the wall 100. Each membrane bag 700 is arranged at intervals along the length of the wall 100. Multiple grouting holes 302 are opened on the flange 303 of the top beam 300. Each grouting hole 302 is arranged at intervals along the extension direction of the top beam 300. Each grouting hole 302 is connected to a membrane bag 700. After the top beam 300 and the ground beam 200 are installed at the top and bottom of the wall 100, grout is injected into the membrane bags 700 through the grouting holes 302. Under the pressure of the grout, the membrane bags 700 expand and fill the irregular pores between the inner side of the flange 303 of the top beam 300 and the wall 100. After the grout solidifies and hardens, the flange 303 of the top beam 300 is in close contact with the wall 100, ensuring that the top beam 300 is firmly installed at the top of the wall 100.

[0037] In order to connect multiple walls 100, in some embodiments, two adjacent walls 100 are aligned and connected by multiple connecting devices 800, with each connecting device 800 spaced apart along the height direction of the wall 100.

[0038] The connecting device 800 includes a connecting rod 810, a waterstop 820, a pad 830, and a nut 840. The side of the wall 100 is provided with an assembly step 104. The connecting rod 810 passes through the splice seam of the two mating walls 100. The nut 840 is tightened on the connecting rod 810 and embedded in the assembly step 104 of the two walls 100. The nut 840 is pressed on the pad 830. The waterstop 820 is pressed on the bottom of the assembly step 104 through the pad 830. The connecting rod 810 pulls the two pads 830, so that the two pads 830 are pressed into the assembly steps 104 of the two adjacent walls 100.

[0039] In order to improve the aesthetics of the joint between two adjacent walls 100, in some embodiments, a decorative strip 900 is provided at the joint between two adjacent walls 100, and the connecting rod 810 of each connecting device 800 is connected to the decorative strip 900.

[0040] Specifically, the decorative strip 900 covers the opening of the mounting steps 104 of the two adjacent walls 100, the decorative strip 900 is kept horizontal with the wall surface of the two adjacent walls 100, and the end of the connecting rod 810 passes through the decorative strip 900 to fix the decorative strip 900.

[0041] In addition, the connecting rod 810 is a flower-shaped bolt structure. Specifically, the end of the connecting rod 810 is designed with a flower-shaped structure 901. This allows the decorative strip 900 to extend from the end of the connecting rod 810, thus enhancing its aesthetic appeal.

[0042] In some embodiments, concrete grout is also injected into the joint between two adjacent walls 100.

[0043] After two adjacent walls 100 are connected by the connecting device 800, concrete grout is injected into the joint between the two adjacent walls 100. The concrete grout solidifies in the front and rear decorative strips 900 and the joint, improving the connection strength.

[0044] The present invention also provides a method for installing prefabricated walls, comprising the following steps: Precast top beam 300 and ground beam 200; A 100mm wall was printed using a 3D printing device. Insert a reinforcing bar 500 through the wall 100 and fix the reinforcing bar 500 in the wall 100 by a positioning device 600; The wall 100 is hoisted onto the ground beam 200, so that the reinforcing bar 500 is fixed in the first reinforcing bar hole 201 of the ground beam 200. The top beam 300 is suspended on the top of the wall 100. Through the observation hole 304, the center line of the top beam 300 is aligned with the center line of the top of the wall 100. The reinforcing bar 500 is aligned and inserted into the second reinforcing bar hole 301. Then the second reinforcing bar hole 301 is fixed to the top beam 300.

[0045] In some embodiments, grout is injected into the grouting holes 302 of the top beam 300, and under the grouting pressure, the membrane bag 700 expands to fill the gap between the inner walls 100 of the flanges 303 of the top beam 300.

[0046] In some embodiments, two adjacent walls 100 are connected by a connecting device 800, and then a decorative strip 900 flush with the wall surface is provided at the joint of the two adjacent walls 100. The decorative strip 900 is connected to the connecting rod 810 of the connecting device 800, and concrete grout is injected into the joint of the two adjacent walls 100.
