Description

Technical Field

[0001] The present invention relates to the technical field, and specifically to a connecting clip for a cast-in-place concrete wall of a thermal insulation board. Background Art

[0002] A cast-in-place concrete wall refers to a wall formed by directly pouring concrete after formwork installation and steel bar binding at a building construction site. It has the characteristics of strong structural integrity, good seismic performance, and high durability. Its construction process includes formwork installation, steel bar arrangement, concrete pouring and vibration, curing, etc., and is commonly used in parts with high requirements for structural strength and stability such as building load-bearing walls, basement walls, or retaining walls. Compared with 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 the quality needs to be strictly controlled.

[0003] A thermal insulation board is a functional material used to reduce heat transfer and improve the heat insulation performance of buildings or equipment. It is usually made of lightweight materials with low thermal conductivity, such as polystyrene, polyurethane, rock wool, glass wool, or phenolic resin, etc. Its core principle is to block heat conduction, convection, and radiation through the closed-cell structure or fiber voids inside the material, thereby reducing heat loss or entry caused by the temperature difference between indoors and outdoors. In the construction field, thermal insulation boards are widely used in walls, roofs, floors, etc., which can significantly improve building energy efficiency and reduce heating or cooling energy consumption. Different materials of thermal insulation boards have different characteristics. For example, XPS boards have strong waterproofness and high compressive strength, rock wool boards have excellent fire resistance, and polyurethane boards have extremely low thermal conductivity. Users can select the appropriate type according to requirements such as fire resistance rating, environmental protection requirements, and cost budget. In addition, some high-end thermal insulation boards also have functions such as sound insulation, moisture-proof, and corrosion resistance, and are important basic materials in modern energy-saving projects.

[0004] When connecting a thermal insulation board to a wall, generally the thermal insulation board is directly pasted on the base wall through an adhesive, which is divided into two types: dot bonding and full bonding. This method is simple in construction and low in cost, but there may be potential safety hazards under extreme climatic conditions. Therefore, the mechanical anchoring method is now mostly adopted, that is, expansion bolts are used to penetrate the thermal insulation board and drive into the base of the wall to achieve the function of stable connection. In this process, workers need to pre-fix the thermal insulation board before driving in the expansion bolts, and the pre-fixation of the thermal insulation board requires the cooperation of another worker, which will lead to the problem of inconvenient construction. At the same time, the contact area between the expansion bolt and the thermal insulation board is small, and during the use process after the installation of the thermal insulation board, it is easy to fall off, affecting the safety of the building. For this reason, we propose a connecting clip for a cast-in-place concrete wall of a thermal insulation board. Summary of the Invention

Specific embodiments

[0035] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0036] Please refer to Figures 1-14 , the present invention provides a technical solution: a connecting clip for an insulation board and a cast-in-place concrete wall, including a cast-in-place concrete wall 1. A stable connection mechanism 3 is provided on the front surface of the cast-in-place concrete wall 1. An insulation board 2 is provided on the outer wall of the stable connection mechanism 3. The stable connection mechanism 3 is used to stably connect the insulation board 2 to the cast-in-place concrete wall 1.

[0037] In a preferred technical solution of this embodiment, the stable 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. Through holes 32 are 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 one end of the inner support arm 341 away from the inner wall of the connecting cylinder 34. A rotating ring member 343 is rotatably connected to the inner wall of the inner support ring 342. A rotating shaft member 344 is rotatably connected to the inner wall of the rotating ring member 343. A first protruding column 345 is fixedly installed on the back of the rotating ring member 343. An arc-shaped transmission rod 346 is rotatably connected to the outer wall of the first protruding column 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 column 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 column 345 is rotatably connected to the outer wall of the second protruding column 349. A translation strip 3481 is fixedly installed on the back of the sliding block 348. A thorn 3482 is fixedly connected to the outer wall of the translation strip 3481. A protruding block 3483 is fixedly connected to the side of the thorn 3482 away from the translation strip 3481. First, the stable connection mechanism 3 is installed on the cast-in-place concrete wall 1. After installing the stable connection mechanism 3, the insulation board 2 is installed. During the installation of the stable connection mechanism 3, first, a hole corresponding to the through hole 32 is opened on the cast-in-place concrete wall 1, and then an expansion bolt is passed through the through hole 32 and driven into the interior of the cast-in-place concrete wall 1, thus completing the installation of the stable connection mechanism 3. During the installation of the insulation board 2, the insulation board 2 is sleeved on the stable connection mechanism 3, and then the movable block 36 is rotated counterclockwise manually from the pull handle 361, which can drive the rotation of the rotating shaft member 344. At this time, the first engaging member 366 and the second engaging member 367 are in an engaged connection state and can be transmitted, thereby synchronously driving the rotation of the rotating ring member 343. During the counterclockwise rotation of the rotating ring member 343, one end of the arc-shaped transmission rod 346 will rotate on the first protruding column 345, and the other end of the arc-shaped transmission rod 346 will rotate on the second protruding column 349, and at the same time, a thrust will be generated on the second protruding column 349, prompting the sliding block 348 to slide on the outer wall of the fixing rod 347. During the sliding of the sliding block 348, the translation strip 3481 will be driven to translate toward the inner wall of the connecting cylinder 34, thereby prompting the thorn 3482 to be inserted into the interior of the insulation board 2, making the insulation board 2 stably connected to the outer wall of the stable connection mechanism 3, avoiding the problem of poor stability when only using expansion bolts for connection, and at the same time increasing the safety of the building.

[0038] In a preferred technical solution of this embodiment, a threaded rod 331 is rotatably connected to the outer wall of the back plate 33 and is located inside the connecting cylinder 34. A moving 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 moving sleeve 332. One end of the connecting rod 333 away from the moving sleeve 332 is rotatably connected to a supporting strip plate 334. The back surface of the supporting strip plate 334 is movably connected to the front surface of the back plate 33. A groove 335 is formed on the side of the supporting strip plate 334 away from the connecting rod 333. The front surface of the threaded rod 331 is fixedly connected to the back surface of the rotating shaft member 344. After the thorn 3482 is fully inserted into the interior of the heat preservation plate 2, the movable block 36 is pulled forward, which can cause the disconnection of the transmission state between the first engaging member 366 and the second engaging member 367. Then, the rotating shaft member 344 can be continuously rotated, thereby driving the threaded rod 331 to rotate. During the rotation of the threaded rod 331, the moving sleeve 332 can be prompted to slide backward on the outer wall of the threaded rod 331. At this time, because the supporting strip plate 334 is in a state of being attached to the back plate 33, through the transmission of the connecting rod 333, the supporting strip plate 334 can be prompted to slide toward the inner wall of the connecting cylinder 34 in a state of being attached to the back plate 33, realizing the opening function. The supporting strip plate 334 can then tightly abut against the inner side of the translation strip plate 3481 to limit the translation strip plate 3481. The convex block 3483 is made of elastic plastic. At the same time, the convex block 3483 will be inserted into the groove 335, so that the supporting strip plate 334 and the translation strip plate 3481 are firmly connected, thereby improving the stability of the limit on the translation strip plate 3481.

[0039] In a preferred technical solution of this embodiment, a connecting circular plate 362 is fixedly connected to the front surface of the rotating shaft member 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 surface of the sliding member 363. A pulling handle 361 is fixedly connected to the front surface of the movable block 36. A sliding sleeve 364 is fixedly connected to the back surface of the sliding member 363. A first elastic member 365 is fixedly installed between the adjacent sides of the sliding sleeve 364 and the connecting circular plate 362. The sliding sleeve 364 is slidably connected to the outer wall of the rotating shaft member 344. A first engaging member 366 is fixedly connected to the back surface of the sliding sleeve 364. A second engaging member 367 is fixedly connected to the front surface of the rotating ring member 343. The second engaging member 367 is movably connected to the inner wall of the first engaging member 366. After the rotating ring member 343 rotates 60°, the thorn 3482 can be fully inserted into the interior of the heat preservation plate 2, and at the same time, the support block 375 will also fully extend. At this time, the movable block 36 can be pulled forward. Through the transmission of the sliding member 363, the sliding sleeve 364 is prompted to slide forward on the outer wall of the rotating shaft member 344, thereby disconnecting the connection between the first engaging member 366 and the second engaging member 367 and releasing the transmission state. Then, the movable block 36 can be continuously rotated, that is, the function of continuously rotating the rotating shaft member 344 is realized.

[0040] In a preferred technical solution of this embodiment, an arc-shaped block 37 is fixedly installed on the front surface of the front plate 35. A rotating arm 371 located on the front surface of the front plate 35 is fixedly installed on the outer wall of the rotating ring member 343. A smooth rod 372 is fixedly installed 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 installed 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 member 374 is fixedly connected to the inner wall of the rotating arm 371. One end of the second elastic member 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 process of installing the heat preservation board 2, manually rotate the movable block 36 counterclockwise from the pull handle 361, which can drive the rotating shaft member 344 to rotate. At this time, the first engaging member 366 and the second engaging member 367 are in an engaged connection state and can be transmitted, thereby synchronously driving the rotating ring member 343 to rotate. The rotating ring member 343 will drive the entire rotating arm 371 to rotate. The second elastic member 374 is in a stretched state in the initial state. After the entire rotating arm 371 rotates, the support block 375 will withdraw from the inside of the arc-shaped block 37. At this time, the arc-shaped block 37 cannot limit the support block 375. Through the initial elastic force of the second elastic member 374, the L-shaped sliding arm 373 can be driven to slide on the outer wall of the smooth rod 372, prompting the support block 375 to extend from the side of the front plate 35 and move to the front surface of the heat preservation board 2, thereby limiting the heat preservation board 2 on the outer wall of the connecting cylinder 34 from the front surface.

[0041] Working principle: When in use, first design the installation point on the cast-in-place concrete wall 1 according to the actual size of the insulation board 2, open a hole corresponding to the through hole 32 on the cast-in-place concrete wall 1, and then drive the expansion screw through the through hole 32 into the inside of the cast-in-place concrete wall 1, and then complete the installation of the stable connection mechanism 3, then put the insulation board 2 on the stable connection mechanism 3, and then manually rotate the movable block 36 counterclockwise from the handle 361, rotate 60°, and drive the rotating shaft 344 to rotate. At this time, the clamp 1 366 and the clamp 2 367 are in a state of bite connection, and transmission can be carried out. The rotating ring 343 is synchronously driven to rotate. During the counterclockwise rotation of the rotating ring 343, one end of the arc transmission rod 346 is prompted to rotate on the No. 1 raised column 345, and the other end of the arc transmission rod 346 is prompted to rotate on the No. 2 raised column 349. At the same time, a thrust is generated on the No. 2 raised column 349, prompting the sliding block 348 to slide on the outer wall of the fixed rod 347. During the sliding of the sliding block 348, the translation strip 3481 is simultaneously driven to translate toward the position of the inner wall of the connecting cylinder 34, thereby prompting the spur 3482 to be inserted into the interior of the insulation board 2, and the rotating ring 343 will also The rotating arm 371 is driven to rotate as a whole, and the support block 375 will be withdrawn from the inner side of the arc block 37. The arc block 37 cannot limit the support block 375 at this time. The initial elastic force of the second elastic member 374 can drive the L-shaped sliding arm 373 to slide on the outer wall of the smooth rod 372, prompting the support block 375 to extend from the side of the front plate 35, and then the insulation board 2 can be limited to the outer wall of the connecting cylinder 34 from the front. Then the movable block 36 is pulled toward the front, and the sliding sleeve 364 is prompted to slide toward the front on the outer wall of the rotating shaft 344 through the transmission of the sliding member 363. This disconnects the clamp 1 366 and the clamp 2 367, releasing the transmission state, and 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, and then the supporting strip 334 slides toward the inner wall of the connecting cylinder 34 in a state of being in contact with the back plate 33, thereby realizing the opening function. The supporting strip 334 can then tightly abut against the inner side of the translation strip 3481, limiting the translation strip 3481, and completing the installation of the insulation board 2.
