Description

Technical Field

[0001] This invention relates to the technical field, specifically to a connecting clip for a cast-in-place concrete wall with insulation board. Background Technology

[0002] Cast-in-place concrete walls refer to walls formed by directly pouring concrete on-site after formwork is erected and steel reinforcement is tied. They are characterized by strong structural integrity, good seismic performance, and high durability. The construction process includes formwork installation, reinforcement arrangement, concrete pouring and vibration, and curing. They are commonly used for load-bearing walls, basement walls, or retaining walls—areas requiring high structural strength and stability. Compared to precast concrete walls, cast-in-place concrete walls can be seamlessly integrated with other parts of the building, but the construction period is longer and requires strict quality control.

[0003] Insulation boards are functional materials used to reduce heat transfer and improve the thermal insulation performance of buildings or equipment. They are typically made of lightweight materials with low thermal conductivity, such as polystyrene, polyurethane, rock wool, glass wool, or phenolic resin. Their core principle is to block heat conduction, convection, and radiation through the closed-cell structure or fiber gaps within the material, thereby reducing heat loss or entry caused by indoor-outdoor temperature differences. In the construction industry, insulation boards are widely used in walls, roofs, and floors, significantly improving building energy efficiency and reducing heating or cooling energy consumption. Different materials of insulation boards have different characteristics. For example, XPS boards are highly waterproof and compressive, rock wool boards have excellent fire resistance, and polyurethane boards have extremely low thermal conductivity. Users can choose the appropriate type based on their fire resistance rating, environmental requirements, and cost budget. Furthermore, some high-end insulation boards also have sound insulation, moisture-proof, and corrosion-resistant functions, making them an important basic material in modern energy-saving projects.

[0004] When connecting insulation boards to walls, they are typically glued directly to the base wall using adhesive, either spot-bonding or full-bonding. This method is simple and low-cost, but may pose safety hazards in extreme weather conditions. Therefore, mechanical anchoring is now more commonly used, where expansion bolts penetrate the insulation board and are driven into the wall base to achieve a stable connection. This process requires pre-fixing the insulation board by one worker before driving in the expansion bolts, which necessitates another worker's assistance, leading to inconvenience. Furthermore, the small contact area between the expansion bolts and the insulation board makes them prone to detachment after installation, affecting building safety. Therefore, we propose a connection clip for insulated boards in cast-in-place concrete walls. Summary of the Invention

[0005] The purpose of this invention is to provide a connecting clip for a cast-in-place concrete wall with insulation board, so as to solve the problems mentioned in the background art, which are inconvenient to construct by directly driving in expansion bolts and have poor connection stability.

A rotating ring is rotatably connected to the inner wall of the inner support ring. A rotating shaft is rotatably connected to the inner wall of the rotating ring.

[0008] Preferably, a first protruding post is fixedly installed on the back of the rotating ring, an arc-shaped transmission rod is rotatably connected to the outer wall of the first protruding post, a fixing rod is fixedly installed on the inner wall of the connecting cylinder, and a sliding block is slidably connected to the outer wall of the fixing rod.

[0009] Preferably, a second protruding column is fixedly connected to the back of the sliding block, and the end of the arc-shaped transmission rod away from the first protruding column is rotatably connected to the outer wall of the second protruding column.

[0010] Preferably, a translation strip is fixedly installed on the back of the sliding block, and a protrusion is fixedly connected to the outer wall of the translation strip. A protrusion is fixedly connected to the side of the protrusion away from the translation strip.

[0011] Preferably, a threaded rod located in the inner cavity of the connecting cylinder is rotatably connected to the outer wall of the back plate, a movable sleeve is threadedly connected to the outer wall of the threaded rod, a connecting rod is rotatably connected to the outer wall of the movable sleeve, and a support plate is rotatably connected to the end of the connecting rod away from the movable sleeve.

[0012] Preferably, the back of the abutment bar is movably connected to the front of the back plate, a groove is provided on the side of the abutment bar away from the connecting rod, and the front of the threaded rod is fixedly connected to the back of the rotating shaft.

[0013] Preferably, a connecting circular plate is fixedly connected to the front of the rotating shaft, a sliding member is slidably connected to the inner wall of the connecting circular plate, a movable block is fixedly connected to the front of the sliding member, and a pull handle is fixedly connected to the front of the movable block.

[0014] Preferably, a sliding sleeve is fixedly connected to the back of the sliding member, and an elastic element is fixedly installed between the sliding sleeve and the adjacent side of the connecting circular plate. The sliding sleeve is slidably connected to the outer wall of the rotating shaft. A first clamp is fixedly connected to the back of the sliding sleeve, and a second clamp is fixedly connected to the front of the rotating ring. The second clamp is movably connected to the inner wall of the first clamp.

[0015] Preferably, an arc-shaped block is fixedly installed on the front side of the front plate, a rotating arm located on the front side of the front plate is fixedly installed on the outer wall of the rotating ring, a smooth rod is fixedly installed on the inner wall of the rotating arm, an L-shaped sliding arm is slidably connected to the outer wall of the smooth rod, and a support block is fixedly installed at the end of the L-shaped sliding arm.

The end of the second elastic element away from the inner wall of the rotating arm is fixedly connected to the outer wall of the L-shaped sliding arm.

[0017] Compared with the prior art, the beneficial effects of the present invention are:

[0018] This invention, through the overall design of a stable connection mechanism, allows users to first install the stable connection mechanism on a cast-in-place concrete wall, and then insert and install the insulation board. During the process, no workers are required to pre-fix the position of the insulation board, reducing the labor intensity of workers and improving the convenience of installation.

[0019] As the user rotates the handle counterclockwise, the rotating ring rotates, causing one end of the arc-shaped transmission rod to rotate on the first protruding post and the other end on the second protruding post. This generates a thrust on the second protruding post, causing the sliding block to slide on the outer wall of the fixed rod. This allows the translation strip to move towards the inner wall of the connecting cylinder, thus causing the protrusion to insert into the interior of the insulation board. This securely connects the insulation board to the outer wall of the stable connection mechanism, avoiding the poor stability issues associated with using only expansion bolts. It also increases the building's safety. Furthermore, the rotation of the rotating ring simultaneously causes the rotating arm to rotate as a whole and retract from the inner side of the arc-shaped block. Through the initial elastic force of the second elastic element, the L-shaped sliding arm slides on the outer wall of the smooth rod, causing the support block to extend from the side of the front plate and move to the front of the insulation board. This allows the insulation board to be positioned on the outer wall of the connecting cylinder from the front, further increasing the stability of the insulation board installed on the stable connection mechanism.

Detailed Implementation

[0035] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0036] Please see Figures 1-14 The present invention provides a technical solution: a connecting clip for a cast-in-place concrete wall with insulation board, including a cast-in-place concrete wall 1, a stabilizing connecting mechanism 3 is provided on the front side of the cast-in-place concrete wall 1, an insulation board 2 is provided on the outer wall of the stabilizing connecting mechanism 3, and the stabilizing connecting mechanism 3 is used to stabilize the insulation board 2 to the cast-in-place concrete wall 1.

[0037] In a preferred embodiment, the stabilizing connection mechanism 3 includes a positioning circular plate 31, which is detachably connected to the outer wall of the cast-in-place concrete wall 1. A through hole 32 is provided on the outer wall of the positioning circular plate 31. A back plate 33 is fixedly connected to the side of the positioning circular plate 31 away from the cast-in-place concrete wall 1. A connecting cylinder 34 is fixedly connected to the side of the back plate 33 away from the positioning circular plate 31. A front plate 35 is fixedly connected to the side of the connecting cylinder 34 away from the back plate 33. An inner support arm 341 is fixedly installed on the inner wall of the connecting cylinder 34. An inner support ring 342 is fixedly installed at the end of the inner support arm 341 away from the inner wall of the connecting cylinder 34. A rotating ring 343 is rotatably connected to the inner wall of the inner support ring 342. A rotating shaft 344 is rotatably connected to the upper part. A first protruding post 345 is fixedly installed on the back of the rotating ring 343. An arc-shaped transmission rod 346 is rotatably connected to the outer wall of the first protruding post 345. A fixing rod 347 is fixedly installed on the inner wall of the connecting cylinder 34. A sliding block 348 is slidably connected to the outer wall of the fixing rod 347. A second protruding post 349 is fixedly connected to the back of the sliding block 348. The end of the arc-shaped transmission rod 346 away from the first protruding post 345 is rotatably connected to the outer wall of the second protruding post 349. A translation strip 3481 is fixedly installed on the back of the sliding block 348. A spike 3482 is fixedly connected to the outer wall of the translation strip 3481. The side of the spike 3482 away from the translation strip 3481... The fixed connection has a protrusion 3483. The stable connection mechanism 3 is pre-installed on the cast-in-place concrete wall 1. After the stable connection mechanism 3 is installed, the insulation board 2 is installed. During the installation of the stable connection mechanism 3, a hole corresponding to the through hole 32 is first opened on the cast-in-place concrete wall 1. Then, the expansion bolt is driven into the interior of the cast-in-place concrete wall 1 through the through hole 32, thus completing the installation of the stable connection mechanism 3. During the installation of the insulation board 2, the insulation board 2 is fitted onto the stable connection mechanism 3. Then, the movable block 36 is manually rotated counterclockwise from the pull handle 361, which can drive the rotating shaft 344 to rotate. At this time, the first clamp 366 and the second clamp 367 are in a meshing connection state, which can carry out transmission and thus synchronize. The rotating ring 343 rotates counterclockwise, causing one end of the arc-shaped transmission rod 346 to rotate on the first protruding column 345 and the other end to rotate on the second protruding column 349. This generates a thrust on the second protruding column 349, causing the sliding block 348 to slide on the outer wall of the fixed rod 347. As the sliding block 348 slides, it also causes the translation strip 3481 to move towards the inner wall of the connecting cylinder 34, thereby causing the protrusion 3482 to insert into the interior of the insulation board 2. This ensures that the insulation board 2 is securely connected to the outer wall of the stable connection mechanism 3, avoiding the problem of poor stability when using only expansion bolts, and increasing the safety of the building.

[0038] In a preferred embodiment, a threaded rod 331 located in the inner cavity of the connecting cylinder 34 is rotatably connected to the outer wall of the back plate 33. A movable sleeve 332 is threadedly connected to the outer wall of the threaded rod 331. A connecting rod 333 is rotatably connected to the outer wall of the movable sleeve 332. A support plate 334 is rotatably connected to the end of the connecting rod 333 away from the movable sleeve 332. The back of the support plate 334 is movably connected to the front of the back plate 33. A groove 335 is provided on the side of the support plate 334 away from the connecting rod 333. The front of the threaded rod 331 is fixedly connected to the back of the rotating shaft 344. After the protrusion 3482 is fully inserted into the interior of the insulation plate 2, the movable block 36 is pulled forward, which can cause the transmission between the first clamp 366 and the second clamp 367 to be disconnected. Then, the rotating shaft 344 can continue to be rotated. The rotation causes the threaded rod 331 to rotate. During the rotation of the threaded rod 331, the movable sleeve 332 slides backward on the outer wall of the threaded rod 331. At this time, because the abutment plate 334 is in a state of being attached to the back plate 33, through the transmission of the connecting rod 333, the abutment plate 334 can slide towards the inner wall of the connecting cylinder 34 in a state of being attached to the back plate 33, realizing the opening function. The abutment plate 334 can then tightly abut against the inner side of the translation plate 3481, limiting the translation plate 3481. The protrusion 3483 is made of elastic plastic. At the same time, the protrusion 3483 is inserted into the inside of the groove 335, so that the abutment plate 334 and the translation plate 3481 are firmly connected, thereby improving the stability of limiting the translation plate 3481.

[0039] In a preferred embodiment, a connecting circular plate 362 is fixedly connected to the front of the rotating shaft 344. A sliding member 363 is slidably connected to the inner wall of the connecting circular plate 362. A movable block 36 is fixedly connected to the front of the sliding member 363. A pull handle 361 is fixedly connected to the front of the movable block 36. A sliding sleeve 364 is fixedly connected to the back of the sliding member 363. An elastic member 365 is fixedly installed between the sliding sleeve 364 and the adjacent side of the connecting circular plate 362. The sliding sleeve 364 is slidably connected to the outer wall of the rotating shaft 344. A locking member 366 is fixedly connected to the back of the sliding sleeve 364. The rotating ring 343 is fixedly connected to the front of the connecting circular plate 362. The first part is fixedly connected to the second part 367, which is movably connected to the inner wall of the first part 366. After the rotating ring 343 rotates 60°, the protrusion 3482 can be fully inserted into the interior of the insulation board 2, and the support block 375 will also be fully extended. At this time, the movable block 36 can be pulled forward. Through the transmission of the sliding part 363, the sliding sleeve 364 is caused to slide forward on the outer wall of the rotating shaft 344, thereby disconnecting the connection between the first part 366 and the second part 367, releasing the transmission state, and then the movable block 36 can continue to rotate, that is, to realize the function of continuing to rotate the rotating shaft 344.

[0040] In a preferred embodiment, an arc-shaped block 37 is fixedly mounted on the front of the front plate 35. A rotating arm 371 located on the front of the front plate 35 is fixedly mounted on the outer wall of the rotating ring 343. A smooth rod 372 is fixedly mounted on the inner wall of the rotating arm 371. An L-shaped sliding arm 373 is slidably connected to the outer wall of the smooth rod 372. A support block 375 is fixedly mounted at the end of the L-shaped sliding arm 373. The outer wall of the support block 375 is movably connected to the inner wall of the arc-shaped block 37. A second elastic element 374 is fixedly connected to the inner wall of the rotating arm 371. The end of the second elastic element 374 away from the inner wall of the rotating arm 371 is fixedly connected to the outer wall of the L-shaped sliding arm 373. During the installation of the insulation board 2, the movable block 36 is manually rotated counterclockwise from the pull handle 361. When the rotating shaft 344 rotates, the first clamp 366 and the second clamp 367 are engaged and can transmit power, which in turn drives the rotating ring 343 to rotate synchronously. The rotating ring 343 will drive the rotating arm 371 to rotate as a whole. The second elastic element 374 is initially stretched. After the rotating arm 371 rotates as a whole, the support block 375 will be withdrawn from the inside of the arc block 37. At this time, the arc block 37 cannot limit the support block 375. Through the initial elastic force of the second elastic element 374, the L-shaped sliding arm 373 can be driven to slide on the outer wall of the smooth rod 372, causing the support block 375 to extend from the side of the front plate 35 and move to the front of the insulation plate 2, thereby limiting the insulation plate 2 on the outer wall of the connecting cylinder 34 from the front.

[0041] Working principle: In use, firstly, design the installation points on the cast-in-place concrete wall 1 according to the actual dimensions of the insulation board 2. Then, drill holes on the cast-in-place concrete wall 1 corresponding to the through holes 32. Next, insert expansion bolts through the through holes 32 into the interior of the cast-in-place concrete wall 1, thus completing the installation of the stable connection mechanism 3. Then, fit the insulation board 2 onto the stable connection mechanism 3. Finally, manually rotate the movable block 36 counterclockwise from the pull handle 361 by 60°. This will drive the rotating shaft 344 to rotate. At this time, the first clamp 366 and the second clamp 367 are in a meshing connection, allowing for transmission. Simultaneously, the rotating ring 343 rotates counterclockwise, causing one end of the arc-shaped transmission rod 346 to rotate on the first protrusion 345 and the other end to rotate on the second protrusion 349, generating a thrust on the second protrusion 349. This causes the sliding block 348 to slide on the outer wall of the fixed rod 347. As the sliding block 348 slides, it simultaneously causes the translation strip 3481 to move towards the inner wall of the connecting cylinder 34, thereby causing the protrusion 3482 to insert into the interior of the insulation plate 2. The rotating ring 343 also... The rotating arm 371 rotates as a whole, causing the support block 375 to retract from the inside of the arc-shaped block 37. At this point, the arc-shaped block 37 can no longer limit the support block 375. Through the initial elastic force of the second elastic element 374, the L-shaped sliding arm 373 slides on the outer wall of the smooth rod 372, causing the support block 375 to extend from the side of the front plate 35. This allows the insulation plate 2 to be limited to the outer wall of the connecting cylinder 34 from the front. Subsequently, the movable block 36 is pulled forward, and through the transmission of the sliding element 363, the sliding sleeve 364 slides forward on the outer wall of the rotating shaft 344. This disconnects the connection between clip 366 and clip 367, releasing the transmission. Then, the movable block 36 can continue to rotate. When the rotating shaft 344 continues to rotate, it can drive the threaded rod 331 to rotate, causing the movable sleeve 332 to slide backward on the outer wall of the threaded rod 331. This causes the support plate 334 to slide towards the inner wall of the connecting cylinder 34 in a state of adhering to the back plate 33, realizing the opening function. The support plate 334 can then press tightly against the inner side of the translation plate 3481, limiting the translation plate 3481, thus completing the installation of the insulation board 2.
