[0002] With the rapid development of urban rail transit construction, the requirements for construction efficiency and quality of subway stations are increasing. Precast assembly structures, due to their advantages such as fast construction speed, controllable quality, and minimal environmental impact, are gradually being used in subway station construction. However, traditional technologies still have the following prominent problems in the connection between precast wall panels and the foundation structure: Insufficient connection reliability: Existing connection structures mostly rely on bolt fixing or welding, which are prone to loosening due to vibration, settlement or construction errors, affecting the overall structural safety. Installation accuracy is difficult to guarantee: the wall panels are prone to misalignment during installation, requiring repeated adjustments, resulting in low construction efficiency and difficulty in achieving rapid centering and positioning; The construction process is complex: traditional connection methods require the cooperation of many people or the use of large machinery, which is cumbersome to operate, has a long construction period, and is costly. Poor adaptability: Under different geological conditions or structural forms, traditional connection structures are difficult to assemble quickly and reliably, which limits the promotion and application of prefabrication technology.

[0015] Compared with the prior art, the beneficial effects of the present invention are: 1. The station wall panel assembly of the present invention is inserted and installed on the top of the wall panel connecting arm assembly. The wall panel connecting arm assembly is pre-cast at a fixed casting position. The anchoring arm at the bottom of the wall panel connecting arm assembly is embedded in the cast concrete. The wall panel connecting arm assembly is fixed through the curing of the concrete. The anchoring claw increases the anchoring force when the wall panel connecting arm assembly is fixed, thereby increasing the reliability of the wall panel connecting arm assembly when fixed.

[0016] 2. The wall panel connecting arm assembly of the present invention has a connecting drive arm assembly at the top center, and multiple sets of fastening arm assemblies and multiple sets of locking arm assemblies are provided on the top edge of the wall panel connecting arm assembly. When the station wall panel assembly is installed and inserted into the wall panel connecting arm assembly, the station wall panel assembly abuts against the connecting drive arm assembly, causing the multiple sets of fastening arm assemblies to extend outward synchronously and fasten onto the back plate of the station wall panel assembly. At the same time, the multiple sets of fastening arm assemblies of the present invention extend outward synchronously around the installation cone arm platform. Through the support of the multiple sets of fastening arm assemblies on the station wall panel assembly, the center of the station wall panel assembly and the center of the wall panel connecting arm assembly are aligned, that is, the alignment processing between the station wall panel assembly and the wall panel connecting arm assembly is realized during the installation process.

[0017] 3. This invention uses multiple sets of locking arm assemblies to lock the assembly and insertion of the station wall panel assembly. When the station wall panel assembly is inserted for assembly, the mounting cone arm platform pushes multiple locking cross arms outward synchronously through locking wedge blocks. After the station wall panel assembly is in place, the locking wedge blocks are reset by pushing springs, thereby limiting and locking the top of the mounting cone arm platform.

[0040] The construction method for the connection structure of prefabricated assembled subway station wall panels includes the following steps: S1. During the pouring and fixing stage of the wall panel connecting arm assembly 200, the anchor arm 202 at the bottom of the wall panel connecting arm assembly 200 is embedded in the poured concrete. The wall panel connecting arm assembly 200 is fixed through the curing of the concrete. The anchoring force of the wall panel connecting arm assembly 200 is increased by the anchoring claw 203. S2. During the insertion and assembly stage of the station wall panel assembly 100, the mounting cone arm platform 103 at the bottom of the subway station wall panel 101 is inserted into the wall panel connecting arm seat 201. At this time, the mounting cone arm platform 103 applies a downward force to the connecting drive arm assembly 300, thereby realizing the downward movement of the connecting drive arm assembly 300. S3. During the assembly stage of fastening arm assembly 400 to station wall panel assembly 100, when the connecting drive arm assembly 300 moves downward, the conical structure of the drive cone arm 301 will drive multiple fastening arm assemblies 400 to extend outward synchronously.

S4. During the assembly and locking stage of the station wall panel assembly 100 by the locking arm assembly 500, when the station wall panel assembly 100 is inserted for assembly, the mounting cone arm platform 103 pushes multiple locking cross arms 501 outward synchronously through the locking inclined block 504. When the station wall panel assembly 100 is in place after being inserted for assembly, the locking inclined block 504 is pushed back to its original position by the push spring 503, so that the locking inclined block 504 limits and locks the top of the mounting cone arm platform 103.

[0041] The working principle of this invention is as follows: To solve the foundation fixing problem during the installation of the station wall panel assembly 100, the station wall panel assembly 100 is inserted and installed on the top of the wall panel connecting arm assembly 200. The wall panel connecting arm assembly 200 is pre-cast at a fixed casting position. Specifically, the wall panel connecting arm assembly 200 includes a wall panel connecting arm seat 201, an anchoring arm 202 is fixedly installed at the bottom of the wall panel connecting arm seat 201, and an anchoring claw 203 is provided on the anchoring arm 202. A first guide side groove 205 is opened on the top outer wall of the wall panel connecting arm seat 201. A second guide side groove 207 is provided on the bottom outer wall, and a return spring 204 is fixedly installed at the bottom of the wall panel connecting arm seat 201. A guide vertical groove 206 is provided in the middle of the inner wall of the wall panel connecting arm seat 201. When the wall panel connecting arm assembly 200 is poured and fixed, the anchoring arm 202 at the bottom of the wall panel connecting arm assembly 200 is embedded in the poured concrete. The wall panel connecting arm assembly 200 is fixed by the curing of the concrete. The anchoring claw 203 increases the anchoring force when the wall panel connecting arm assembly 200 is fixed. In this way, the reliability of the wall panel connecting arm assembly 200 is increased.

[0042] Based on the above, in order to solve the problem of rapid assembly of the station wall panel assembly 100, the wall panel connecting arm assembly 200 of the present invention is provided with a connecting drive arm assembly 300 at the top center, and multiple sets of fastening arm assemblies 400 and multiple sets of locking arm assemblies 500 are provided on the top edge of the wall panel connecting arm assembly 200. When the station wall panel assembly 100 is installed and inserted into the wall panel connecting arm assembly 200, the station wall panel assembly 100 abuts against the connecting drive arm assembly 300 during assembly, causing the multiple sets of fastening arm assemblies 400 to extend outward and fasten onto the back plate of the station wall panel assembly 100 simultaneously. Specifically, the fastening arm assembly 400 includes a fastening mechanism. A horizontal arm 401 is provided with a roller 402 and a clamping end plate 403 at one end, and a clamping arm frame 405 at the other end. A clamping block 406 is provided on the top of the clamping arm frame 405. A clamping spring 404 is fitted on the clamping horizontal arm 401. The clamping horizontal arm 401 slides through the second guide side groove 207 and the wall panel connecting arm seat 201. The clamping spring 404, the clamping end plate 403, and the roller 402 are located inside the wall panel connecting arm seat 201, and the clamping arm frame 405 is located outside the wall panel connecting arm seat 201. The clamping spring 404 pushes the clamping end plate 403, and the roller 402... 2. Inside the wall panel connecting arm seat 201, there is an inward pushing structure. The roller 402 abuts against the drive cone arm 301. In actual use, during the insertion and assembly stage of the station wall panel assembly 100, the mounting cone arm 103 at the bottom of the subway station wall panel 101 is inserted into the wall panel connecting arm seat 201. At this time, the mounting cone arm 103 applies a downward force to the connecting drive arm assembly 300, realizing the downward movement of the connecting drive arm assembly 300. When the connecting drive arm assembly 300 moves downward, the cone-shaped structure of the drive cone arm 301 will drive multiple snap-fit ​​arm assemblies 400 to extend outward synchronously. Through the synchronous extension of the snap-fit ​​arm assemblies 400... The fastening block 406 at the top of the fastening arm 405 is fastened into the fastening slot 105 on the multiple installation limiting arms 104. Through this structure, the station wall panel assembly 100 and the wall panel connecting arm assembly 200 can be quickly assembled. At the same time, the multiple sets of fastening arm assemblies 400 of this invention expand outward synchronously around the installation cone arm platform 103. Through the support of the multiple sets of fastening arm assemblies 400 on the station wall panel assembly 100, the center of the station wall panel assembly 100 and the center of the wall panel connecting arm assembly 200 are aligned. That is, during the installation process, the alignment between the station wall panel assembly 100 and the wall panel connecting arm assembly 200 is achieved.

[0043] To address the locking issue during assembly of the station wall panel assembly 100 onto the wall panel connecting arm assembly 200, this invention employs multiple locking arm assemblies 500 to lock the assembly and insertion of the station wall panel assembly 100. Specifically, each locking arm assembly 500 includes a locking cross arm 501, with a cross arm end plate 502 and a locking inclined block 504 fixedly mounted at both ends. A push spring 503 is fitted onto the locking cross arm 501. The locking cross arm 501 slides through the wall panel connecting arm seat 201 via a first guide side groove 205. The locking inclined block 504 and the push spring 503 are located inside the wall panel connecting arm seat 201, while the cross arm end plate 502 is located outside the wall panel connecting arm seat 201. The push spring 503 pushes the locking inclined block 504, which is in an inward pushing structure inside the wall panel connecting arm seat 201. When the station wall panel assembly 100 is inserted for assembly, the mounting cone arm platform 103 pushes multiple locking cross arms 501 outward synchronously through the locking inclined block 504. After the station wall panel assembly 100 is inserted into place, the push spring 503 pushes the locking inclined block 504 to reset, thereby limiting and locking the top of the mounting cone arm platform 103. Through this structure, the station wall panel assembly 100 is locked on the wall panel connecting arm assembly 200, ensuring the firmness of the station wall panel assembly 100 when assembled on the wall panel connecting arm assembly 200.
