Description

Technical Field

[0001] This invention relates to the field of continuous wall installation technology, and in particular to a prefabricated assembled steel underground continuous wall installation docking component. Background Technology

[0002] A diaphragm wall is a foundation engineering project where a trenching machine is used on the ground to excavate a narrow, deep trench along the perimeter of the deep excavation project, under the condition of mud wall protection. After cleaning the trench, a steel cage is suspended in the trench, and then underwater concrete is poured in using the tremie method to form a unit trench segment. This process is repeated segment by segment to build a continuous reinforced concrete wall underground, which serves as a water interception, seepage prevention, load-bearing, and water-retaining structure.

[0003] Currently, existing technologies connect multiple diaphragm walls together using bolts, and steel bars are used between the diaphragm walls in the deep trench to support each other and prevent the diaphragm walls from tilting. This connection method increases construction costs and delays construction progress. Therefore, this invention proposes a prefabricated assembled steel underground diaphragm wall installation and connection component. Summary of the Invention

The folding mechanism can also splice multiple pieces together during the folding process of the steel cage frame; the connecting component includes a fixed frame, a reinforcing bracket is fixedly connected to the outside of the fixed frame, and side protection sheet metal is fixedly connected to both ends of the fixed frame. Mounting sheet metal is fixedly connected to the surfaces of the two side protection sheet metals, and mounting holes are opened in each mounting sheet metal. Several evenly distributed rectangular support frames are fixedly connected inside the fixed frame.

[0006] In at least some embodiments, each of the rectangular support frames has a transverse sheet metal fixed to its upper and lower outer side walls, and each of the transverse sheet metal is configured as an L-shape.

[0007] In at least some embodiments, T-shaped sheet metal is fixed to the upper and lower sides of the inner sidewall of each rectangular support frame, and mounting bolts are installed in each mounting hole.

[0008] In at least some embodiments, the folding mechanism includes a connecting plate and a mounting plate. A central shaft is fixedly connected to one end of the lower surface of the connecting plate, and a mounting groove is provided at one end of the mounting plate. The central shaft is installed in the mounting groove, and the connecting plate is located above the mounting plate.

[0009] In at least some embodiments, limit blocks are fixedly connected to both ends of the lower surface of the connecting plate and the mounting plate, each limit block is located within the mounting sheet metal, and each limit block is provided with a threaded hole.

[0010] In at least some embodiments, the upper surface of the connecting plate is provided with an arc-shaped sliding groove, the upper surface of the mounting plate is provided with a through hole, one end of the through hole is provided with a limiting slot, and the inner sidewall of the through hole is provided with a limiting groove on the side near the limiting slot.

[0011] In at least some embodiments, a plug is provided in the limiting slot, a rotating connecting rod is fixedly connected to the upper surface of the plug, a side fixing rod is fixedly connected to both ends of the upper surface of the rotating connecting rod, a push-pull handle is fixedly connected between the two side fixing rods, a transmission connecting rod is rotatably installed on one side fixing rod, a slider is fixedly connected to one end of the lower surface of the transmission connecting rod, and the slider is slidably installed in the arc-shaped groove.

[0012] In at least some embodiments, a side sliding block is slidably installed in the limiting groove, and a clamping plate is fixedly connected between two side sliding blocks. One end of the clamping plate is in close contact with the insert block, and a connecting member is fixedly connected to the other end of the clamping plate. A pull rod is rotatably installed in the connecting member.

[0013] In at least some embodiments, a rotating seat is fixedly connected to the lower end of the pull rod, a lever is fixedly connected to one side of the rotating seat, and a push rod is fixedly connected to the other side of the rotating seat.

[0014] In at least some embodiments, a mounting ring is provided on one side of the mounting groove, a rotating seat is rotatably mounted in the middle of the mounting ring, the rotating seat is fixed to one side surface of the abutment plate, and an extension plate is fixed to one end of the mounting ring, with one side of the extension plate closely attached to the push rod.

[0015] Compared with the prior art, the advantages and positive effects of the present invention are as follows:

[0016] In this invention, the limiting blocks on the lower surfaces of the connecting plate and the mounting plate are inserted into the mounting sheet metal. Then, the limiting blocks and the mounting sheet metal are firmly connected together by mounting bolts. The connecting plate and the mounting plate are set horizontally, and the central axis of the connecting plate moves into the mounting groove. Then, pushing the lever will drive the pulling rod and the push rod to rotate around the rotating seat. When one side of the push rod contacts the extension plate, it will drive the extension plate mounting ring to rotate around the rotating seat. Then, the mounting ring can install the central axis between the mounting ring and the mounting groove, thus completing the splicing of the connecting plate and the mounting plate, and then assembling the two steel cage frames.

[0017] In this invention, pulling the lever pushes the abutment plate to move horizontally along the limiting groove. One end of the abutment plate then fixes the insert block in the limiting slot, thus fixing the transmission link. After the connecting plate and the mounting plate are assembled, pulling the push-pull handle moves the slider along the arc-shaped slide groove via the transmission link. When the slider moves to one end of the arc-shaped slide groove, the transmission link and the transmission link become parallel, and the two steel cage frames become parallel, thus achieving the docking of the two steel cage frames. Simultaneously, when the slider moves to the other end of the arc-shaped slide groove, the transmission link and the transmission link... The connecting plate and the mounting plate will rotate around the central axis, thus folding the steel cage frame. This folding facilitates the adjustment of the angle of the steel cage frame and allows for the placement of prefabricated components between the steel cage frames, thereby accelerating construction efficiency and enabling the rapid construction of curved walls. Through the rapid assembly and splicing of the connecting plate and the mounting plate, the two steel cage frames are connected, facilitating the subsequent pouring of continuous walls. Furthermore, after the connecting plate and the mounting plate are spliced, they can rotate around the central axis to adjust the angle of the two steel cage frames, thereby achieving the rapid construction of curved walls.

[0018] In this invention, the rectangular support frame, T-shaped sheet metal, and horizontal sheet metal need to be inserted into both sides of the continuous wall during the prefabrication process. After the concrete of the steel cage frame has solidified, it can be firmly connected to the continuous wall. The rectangular support frame, T-shaped sheet metal, and horizontal sheet metal can form a solid rectangular support structure, thereby strengthening the support and seismic resistance of the steel cage frame. By fixing the frame, reinforcing the bracket, and side protection sheet metal, the concrete at both edges of the steel cage frame can be protected. On the one hand, it strengthens the support of the steel cage frame, and on the other hand, it can also protect the corners of the steel cage frame. Attached Figure Description

[0029] To better understand the above-mentioned objectives, features, and advantages of the present invention, the present invention will be further described below in conjunction with the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0030] Numerous specific details are set forth in the following description in order to provide a full understanding of the invention. However, the invention may also be practiced in other ways than those described herein, and therefore the invention is not limited to the specific embodiments disclosed in the following specification.

[0031] Implementation examples, based on Figures 1-9 This invention provides a prefabricated assembled steel diaphragm wall installation and connection component, including a steel cage frame 100. Connecting components 200 are provided on both sides of the steel cage frame 100. A folding mechanism 300 is installed between each adjacent connecting component 200. The folding mechanism 300 can also splice multiple sections together during the folding process of the steel cage frame 100. Figure 3 As shown, the connecting component 200 includes a fixed frame 201, a reinforcing bracket 202 fixedly connected to the outside of the fixed frame 201, and side protection sheet metal 203 fixedly connected to both ends of the fixed frame 201. Mounting sheet metal 204 is fixedly connected to the surface of each of the two side protection sheet metal 203, and each mounting sheet metal 204 has a mounting hole 205. Several evenly distributed rectangular support frames 206 are fixedly connected inside the fixed frame 201. The fixed frame 201, the reinforcing bracket 202, and the side protection sheet metal 203 can protect the concrete at both edges of the steel cage frame 100, thereby strengthening the support of the steel cage frame 100 and protecting the corners of the steel cage frame 100.

[0032] like Figure 4 As shown, each rectangular support frame 206 has a horizontal sheet metal 208 fixedly connected to its upper and lower outer sidewalls.

Each mounting hole 205 has a mounting bolt 209 installed in it. The rectangular support frame 206, T-shaped sheet metal 207, and horizontal sheet metal 208 need to be inserted into both sides of the continuous wall during the prefabrication of the continuous wall. After the concrete of the steel cage frame 100 has solidified, they can be firmly connected to the continuous wall. The rectangular support frame 206, T-shaped sheet metal 207, and horizontal sheet metal 208 can form a solid rectangular support structure, thereby strengthening the support and seismic resistance of the steel cage frame 100.

[0033] like Figures 6-9The folding mechanism 300 shown includes a connecting plate 302 and a mounting plate 311. A central shaft 306 is fixedly connected to one end of the lower surface of the connecting plate 302. A mounting groove 315 is formed at one end of the mounting plate 311, and the central shaft 306 is installed in the mounting groove 315. The connecting plate 302 is located above the mounting plate 311. Limiting blocks 301 are fixedly connected to both ends of the lower surfaces of the connecting plate 302 and the mounting plate 311, respectively. Each limiting block 301 is located within the mounting sheet metal 204, and each limiting block 301 has a threaded hole. An arc-shaped sliding groove 303 is formed on the upper surface of the connecting plate 302. A recessed hole 313 is formed through the upper surface of the mounting plate 311, and a limiting slot 312 is formed at one end of the recessed hole 313. A limiting groove 314 is formed on the inner side wall of the recessed hole 313 near the limiting slot 312. An insert block 309 is provided in the limiting slot 312. A rotating connecting rod 308 is fixedly connected to the upper surface of the insert block 309. Side fixing rods 310 are fixedly connected to both ends of the upper surface of the rotating connecting rod 308. A push-pull handle 307 is fixedly connected between the two side fixing rods 310. A transmission connecting rod 304 is rotatably mounted on one side fixing rod 310. A slider 305 is fixedly connected to one end of the lower surface of the transmission connecting rod 304. The slider 305 is slidably mounted in the arc-shaped sliding groove 303. A side sliding block 323 is slidably mounted in the limiting groove 314. A pressing plate 325 is fixedly connected between the two side sliding blocks 323, with one end of the pressing plate 325 tightly abutting against... The insert block 309 has a connector 324 fixedly connected to the other end of the abutment plate 325. A pull rod 322 is rotatably installed inside the connector 324. A rotating seat 319 is fixedly connected to the lower end of the pull rod 322. A lever 321 is also fixedly connected to one side of the rotating seat 319, and a push rod 320 is fixedly connected to the other side of the rotating seat 319. An installation ring 316 is provided on one side of the mounting groove 315. A rotating seat 317 is rotatably installed in the middle of the installation ring 316. The rotating seat 317 is fixedly connected to one side surface of the abutment plate 325. An extension plate 318 is fixedly connected to one end of the installation ring 316. One side of the extension plate 318 is in close contact with the push rod 320. The limiting block 301 on the lower surface of the connecting plate 302 and the mounting plate 311 is inserted into the mounting sheet metal 204. Then, the limiting block 301 and the mounting sheet metal 204 are firmly connected together by the mounting bolts 209, and the connecting plate 302 and the mounting plate 311 are set horizontally. The central axis 306 of the connecting plate 302 will move into the mounting groove 315. Then, pushing the lever 321 will drive the pulling rod 322 and the push rod 320 to rotate around the rotating seat 319. When one side of the push rod 320 contacts the extension plate 318, it will drive the mounting ring 316 of the extension plate 318 to rotate around the rotating seat 317. Then, the mounting ring 316 can install the central axis 306 between the mounting ring 316 and the mounting groove 315, thus completing the splicing of the connecting plate 302 and the mounting plate 311, and then assembling the two steel cage frames 100.Simultaneously, the pull rod 322 on one side can push the abutment plate 325 to move horizontally along the limiting groove 314. One end of the abutment plate 325 will fix the insert block 309 in the limiting slot 312, thereby fixing the rotating connecting rod 308. After the connecting plate 302 and the mounting plate 311 are assembled, pulling the push-pull handle 307 will move the slider 305 along the arc-shaped slide groove 303 by rotating the connecting rod 308 and the transmission connecting rod 304. When the slider 305 moves to one end of the arc-shaped slide groove 303, the rotating connecting rod 308 will move horizontally along the arc-shaped slide groove 303. Rod 308 and transmission connecting rod 304 will be in a parallel state, and the two steel cage frames 100 will be in a parallel state, thus achieving the docking of the two steel cage frames 100. Simultaneously, when slider 305 moves to the other end of arc-shaped slide 303, the rotating connecting rod 308 and transmission connecting rod 304 will rotate. To facilitate the pouring of the continuous wall, the connecting plate 302 and mounting plate 311 are set to a quick assembly splicing method. Then, the connecting plate 302 and mounting plate 311 will rotate around the central axis 306, achieving the folding of the steel cage frame 100. This folding facilitates the adjustment of the angle of the steel cage frame 100. Furthermore, after splicing, the connecting plate 302 and mounting plate 311 can rotate around the central axis 306 to adjust the angle of the two steel cage frames 100, thereby achieving the rapid construction of the arc-shaped wall.

[0034] The working principle of this invention is as follows: First, the rectangular support frame 206, T-shaped sheet metal 207, and horizontal sheet metal 208 are connected together with the reinforcing cage frame 100 by bolts. The rectangular support frame 206, T-shaped sheet metal 207, and horizontal sheet metal 208 can form a solid rectangular support structure, thereby strengthening the support and seismic resistance of the reinforcing cage frame 100. By fixing the frame 201, reinforcing bracket 202, and side protection sheet metal 203, the concrete at both edges of the reinforcing cage frame 100 can be protected, thus strengthening the support of the reinforcing cage frame 100 and protecting the reinforcing steel. The corners of the cage frame 100 provide protection. The limiting blocks 301 on the lower surfaces of the connecting plate 302 and mounting plate 311 are inserted into the mounting sheet metal 204. The limiting blocks 301 and mounting sheet metal 204 are then securely connected together using mounting bolts 209. With the connecting plate 302 and mounting plate 311 positioned horizontally, the central axis 306 of the connecting plate 302 moves into the mounting groove 315. Pushing the lever 321 then causes the pulling rod 322 and push rod 320 to rotate around the rotating seat 319. When one side of the push rod 320 contacts the extension plate 318, it drives the extension... The mounting ring 316 of plate 318 rotates around the rotating seat 317, and then the mounting ring 316 can install the central shaft 306 between the mounting ring 316 and the mounting groove 315, thus completing the splicing of the connecting plate 302 and the mounting plate 311, and then assembling the two steel cage frames 100. At the same time, the pull rod 322 on one side can push the clamping plate 325 to move horizontally along the limiting groove 314. One end of the clamping plate 325 will fix the insert 309 in the limiting slot 312, thereby fixing the rotating connecting rod 308. After the connecting plate 302 and the mounting plate 311 are spliced, the pull rod 322 can be used to fix the connecting plate 308. The push-pull handle 307 can be moved by rotating the connecting rod 308 and the transmission connecting rod 304, causing the slider 305 to move along the arc-shaped slide groove 303. When the slider 305 moves to one end of the arc-shaped slide groove 303, the rotating connecting rod 308 and the transmission connecting rod 304 will be in a parallel state, and the two steel cage frames 100 will be in a parallel state, thereby realizing the docking of the two steel cage frames 100. At the same time, when the slider 305 moves to the other end of the arc-shaped slide groove 303, the rotating connecting rod 308 and the transmission connecting rod 304 will rotate, and then the connecting plate 302 and the mounting plate 311 will rotate around the central axis 306, realizing the folding of the steel cage frame 100. The folding is to facilitate the adjustment of the angle of the steel cage frame 100, and to facilitate the placement of prefabricated components between the steel cage frames, thereby speeding up the construction efficiency.

Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments that can be applied to other fields.
