[0029] like Figure 1 to Figure 7 As shown, the present invention provides an assembled building wall, comprising: a wall 1, two adjacent walls 1 are spliced ​​by a first positioning component and a second positioning component, the first positioning component comprises a positioning groove 2 arranged on one of the two adjacent walls 1, and a positioning plate 3 arranged on the other of the two adjacent walls 1, the positioning plate 3 cooperates with the positioning groove 2, two groups of oppositely arranged inner side walls in the positioning groove 2 are both provided with a first inclined edge 201 inclined away from the center direction of the positioning groove 2, a plurality of limit blocks 202 are arranged side by side on the two opposite side walls in the length direction of the side wall of the wall 1 in the positioning groove 2, a limit groove 203 is formed between two adjacent limit blocks 202 on the same side wall, and the limit groove 203 is formed between the two adjacent limit blocks 202 on the same side wall. 3, the two side walls opposite to each other in the width direction of the side wall of the wall 1 are provided with second inclined edges 204 inclined away from the center direction of the limiting groove 203, the positioning plate 3 is provided with a limiting block 301 that matches the limiting groove 203 one by one, the second positioning component includes two relatively arranged sliders 4 slidably mounted on the bottom wall of the positioning groove 2, and a slide groove 5 arranged on the positioning plate 3, the slide groove 5 can cover the slider 4 and the slider 4 can be limited to slide in the slide groove 5, the limiting block 202 is provided with a socket 205, the two relatively arranged sockets 205 are located on the same axis, the positioning plate 3 is slidably mounted with an insertion rod 302 that matches the socket 205, and sliding the slider 4 can enable the insertion rod 302 to be inserted into the socket 205.

[0030] When the two adjacent walls 1 are joined, the wall 1 is hoisted to a preset position by a hoisting device, and the positioning plate 3 slides into the positioning groove 2. The design of the first inclined edge 201 allows a gap to exist between the bottom wall of the positioning plate 3 and the top wall of the positioning groove 2, thereby increasing the positioning range. The first positioning assembly realizes the rough positioning of the positioning plate 3 and the positioning groove 2. During the process of the positioning plate 3 sliding into the positioning groove 2, due to the limitation of the first inclined edge 201, the positioning plate 3 directly slides into the positioning groove 2 to achieve a perfect fit, so as to limit the adjacent wall 1 in the horizontal direction of the side wall of the wall 1. At this time, the slide groove 5 covers the setting of the slider 4, and then the slider 4 is slid to drive the insertion rods 302 on both sides to slide and extend into the insertion hole 205, thereby limiting the adjacent wall 1 in the axial direction of the side wall of the wall 1.

[0031] This solution can roughly position the wall 1 during splicing through the first positioning component, and limit the displacement of adjacent walls 1 in the horizontal direction of the side wall of the wall 1, and can achieve a seamless effect without the need for auxiliary devices; the adjacent walls 1 can be fixed through the second positioning component to limit the displacement of adjacent walls 1 in the axial direction of the side wall of the wall 1; thereby achieving rapid assembly and improving assembly efficiency.

[0032] In one embodiment of the present invention, the positioning plate 3 is provided with mounting holes 303 corresponding to the insertion holes 205 one by one, the mounting holes 303 are connected to the slide groove 5, the insertion rod 302 is slidably installed in the mounting holes 303, the first end of the insertion rod 302 extends to the slide groove 5 and an extrusion block 304 is fixed therein, and a spring 305 is fixedly installed between the extrusion block 304 and the inner wall of the adjacent slide groove 5.

[0033] In this solution, before the positioning plate 3 is matched with the positioning groove 2, the second end of the insertion rod 302 does not extend out of the mounting hole 303. When the positioning plate 3 is matched with the positioning groove 2, the slide groove 5 covers the slider 4, and the two sliders 4 are located between the two oppositely arranged extrusion blocks 304. Then, the two sliders 4 are slid so that the sliders 4 drive the extrusion blocks 304 to slide, thereby inserting the insertion rod 302 into the insertion hole 205. During disassembly, the two sliders 4 are slid so that the two sliders 4 are close to each other. At this time, under the action of the spring 305, the insertion rod 302 returns to the mounting hole 303 for easy disassembly.

[0034] In one embodiment of the present invention, a tooth column 101 is rotatably mounted on the wall 1, and the axial direction of the tooth column 101 is consistent with the length direction of the side wall of the wall 1. The tooth column 101 is arranged between two sliders 4, and a rack 401 meshing with the tooth column 101 is fixedly arranged on the two sliders 4. The racks 401 on the two sliders 4 are arranged symmetrically about the axis of the tooth column 101. The first slider of the two sliders 4 is provided with a groove 402 that cooperates with the rack arranged on the second slider. The first end of the tooth column 101 is provided with a There is a keyway 102, and a screw 103 is keyed in the keyway 102. The side wall of the wall 1 is provided with a threaded hole 104 that cooperates with the screw 103. The screw 103 is limitedly threadedly connected in the threaded hole 104. Rotating the screw 103 to move the screw 103 axially to a first limiting position can enable the two sliders 4 to move away from each other so that the insertion rod 302 can be inserted into the insertion hole 205. Reversely rotating the screw 103 to move the screw axially to a second limiting position can enable the two sliders 4 to move closer to each other so that the insertion rod 302 can be disengaged from the insertion hole 205.

[0035] In this solution, the first limiting position is the first side wall of the threaded hole 104 close to the tooth column 101, and the second limiting position is the second side wall of the threaded hole 104 away from the tooth column 101. When the screw 103 is rotated until the screw 103 abuts against the first side wall of the threaded hole 104, there is no need to continue rotating the screw 103 due to the resistance of the first side wall; when the screw 103 is rotated until the screw 103 abuts against the second side wall of the threaded hole 104, there is no need to continue rotating the screw 103 due to the resistance of the second side wall; before the positioning plate 3 is inserted into the positioning groove 2, the screw 103 is located at the second limiting position. The distance between the two relatively arranged sliders 4 is the shortest, so that when the positioning plate 3 is inserted into the positioning groove 2, the slide groove 5 can easily cover the slider 4; after the positioning plate 3 is inserted into the positioning groove 2, the screw 103 is rotated so that the screw 103 is axially in the first limit position. When the screw 103 rotates, since the screw 103 is connected to the tooth column 101 through the keyway 102, the tooth column 101 can rotate, thereby driving the two sliders 4 away from each other, so that the insertion rod 302 is inserted into the socket 205; by setting the screw 103, the stability of the slider 4 after driving the insertion rod 302 to insert into the socket 205 is guaranteed.

[0036] In one embodiment of the present invention, a buffer groove 6 connected to the positioning groove 2 is provided on the wall 1, the top wall of the buffer groove 6 and the bottom wall of the positioning groove 2 are located in the same plane, a support plate 601 is slidably installed in the buffer groove 6, and an elastic pad 602 is fixedly installed between the support plate 601 and the bottom wall of the buffer groove 6.

[0037] In this solution, after the positioning plate 3 slides along the positioning groove 2, it falls into the positioning groove 2, and the positioning plate 3 is buffered by the elastic pad 602 and the support plate 601, thereby improving the safety of the installation process.

[0038] In one embodiment of the present invention, two symmetrical L-shaped limit plates 501 are fixedly provided on the top wall of the slide groove 5, and a limit slide groove for installing a spring 502 is formed between the two L-shaped limit plates 501. The spring 502 is installed in the limit slide groove for limiting sliding. The spring 502 can slide out of the slide groove 5 along the length direction of the limit slide groove, and can limit sliding along the width direction of the limit slide groove.

[0039] In this solution, after the slide groove 5 covers the slider 4, the top wall of the slider 4 abuts against the spring leaf 502, and can squeeze and deform the spring leaf 502, so that the two ends of the spring leaf 502 extend in the direction close to the L-shaped limit plate 501 respectively. At this time, the top wall of the slider 4 abuts against the spring leaf 502, and the spring leaf 502 is arranged to prevent the cavity formed by the positioning plate 3 and the positioning groove 2 from being deformed due to thermal expansion and contraction.

[0040] In one embodiment of the present invention, the sliding block 4 is provided with a third inclined edge 403 on the side close to the insertion rod 302 , and the extrusion block 304 is in contact with the third inclined edge 403 on the side close to the third inclined edge 403 .

[0041] In this solution, by providing the third inclined edge 403 , when the positioning plate 3 slides into the positioning groove 2 , it can slide down along the third inclined edge 403 provided on the sliding block 4 .

[0042] A construction method for an assembled building wall comprises the following steps:

[0043] S1: When splicing two adjacent walls 1, after the first wall of the two walls 1 is fixedly installed at a preset position, the second wall of the two walls 1 is hoisted by a hoisting device to be close to the first wall, and after rough positioning by the first positioning component, the positioning plate 3 on the second wall slides down along the first inclined edge 201 on the positioning groove 2 on the first wall so that the positioning plate 3 and the positioning groove 2 are automatically matched, wherein, before the rough positioning, the screw rod 103 needs to be rotated so that the screw rod 103 is axially in the second limiting position so that the two sliders 4 are at the shortest distance, so that when the slide groove 5 covers the slider 4, the two sliders 4 are located between the two extrusion blocks 304;

[0044] S2: Rotate the screw rod 103 to move the screw rod 103 axially to the first limiting position, so as to drive the tooth column 101 to rotate, so as to drive the two racks 401 to move in opposite directions to move the two sliders 4 away from each other so as to insert the insertion rod 302 into the insertion hole 205 .

[0045] The working principle of the present invention is as follows: when splicing two adjacent walls 1, after the first wall of the two walls 1 is fixedly installed at a preset position, the screw rod 103 is rotated so that the screw rod 103 is axially located at the second limiting position so that the two sliders 4 are at the shortest distance, such as Figure 2, and then the second wall of the two walls 1 is hoisted by the hoisting equipment to be close to the first wall, so that the positioning plate 3 slides into the positioning groove 2. After the positioning plate 3 slides into the positioning groove 2, it falls on the support plate 601 and plays a buffering role through the elastic pad 602. After the positioning plate 3 and the positioning groove 2 are closed together, the slide groove 5 covers the slider 4, and the two sliders 4 are located between the two insertion rods 302. Then the screw rod 103 is rotated to make the screw rod 103 axially in the first limit position. When the screw rod 103 rotates, since the screw rod 103 is connected to the tooth column 101 through the keyway 102, the tooth column 101 can rotate, thereby driving the two racks 401 to move away from each other, so that the two sliders 4 move away from each other, thereby pushing the insertion rod 302 into the insertion hole 205 through the slider 4.

[0046] Finally, it should be noted that the above preferred embodiments are only used to illustrate the technical solutions of the present invention rather than to limit it. Although the present invention has been described in detail through the above preferred embodiments, those skilled in the art should understand that various changes can be made in form and details without departing from the scope defined by the claims of the present invention.
