Abstract
Description
Technical Field
[0001] This utility model relates to the field of fair-faced concrete wall processing technology, and in particular to a crack control structure for fair-faced concrete walls. Background Technology
[0002] Fair-faced concrete walls are reinforced concrete walls cast directly into shape without any additional finishing or plastering. Their natural and simple appearance showcases the inherent beauty of concrete, making them an environmentally friendly and highly durable building material. Because there is no additional finishing or plastering, crack control in fair-faced concrete walls is a crucial aspect of the design and construction process.
[0003] Existing crack control structures use induced cracks to control cracks during use. However, cracks in fair-faced concrete walls can be caused by a variety of factors. Vibration, as a core step in concrete construction, ensures thorough and uniform mixing of aggregates and cement paste, effectively removing air bubbles and excess water, thereby significantly improving the density and overall strength of the concrete. However, the current construction characteristics of prefabricated fair-faced concrete walls often require the pouring of multiple walls at once. In practice, due to factors such as tight construction schedules, space constraints, or human negligence, insufficient vibration often occurs in some fair-faced concrete walls, a phenomenon known as "missed vibration." This "missed vibration" not only directly affects the homogeneity of the concrete but also weakens the compactness of its internal structure, leading to more cracks and ultimately reducing the overall quality of the fair-faced concrete wall.

[0034] refer to Figures 1 to 6 This invention describes a crack control structure for fair-faced concrete walls according to an embodiment of the present invention.
[0035] like Figures 1 to 6 As shown, the crack control structure for fair-faced concrete walls according to an embodiment of this utility model includes: an installation structure 2, which includes a first connecting frame 21, which is U-shaped and has locking mechanisms at both ends. The first connecting frame 21 is locked onto the pouring pipe 1 by the locking mechanisms; a support structure 3, which is fixed to the installation structure 2. A connecting rod 4 is fixedly connected to one end of the support structure 3, and a driving structure 5 is fixedly connected to the end of the connecting rod 4 away from the support structure 3; and a vibrator 6, which is inserted into the driving structure 5. A vibrator pipe 8 is connected to the top of the vibrator 6, and a vibrator 9 is connected to the end of the vibrator pipe 8 away from the vibrator 6.
[0036] The locking mechanism includes a fixed arc plate 22, one end of which is movably connected to a movable arc plate 23 via a pivot. The fixed arc plate 22 and the movable arc plate 23 are both threadedly connected to a fastening nut 24. By rotating the fastening nut 24, the fixed arc plate 22 and the movable arc plate 23 are pressed against the surface of the casting pipe 1. A scale 25 is provided on the side of the first connecting frame 21 away from the locking mechanism.
[0037] The vibrator 6 is fixedly connected to the pouring pipe 1 through an installation and support mechanism. When the pouring pipe 1 moves during the pouring operation, it can naturally drive the vibrator 6 to move synchronously. After pouring, the material can be vibrated to avoid the phenomenon of "missed vibration" and thus control the cracks in the precast concrete wall. The vibrator 6 is inserted into the material, and the vibration of the material by the vibrator 6 makes the aggregate and cement paste in the concrete fully mixed, removes internal air bubbles and excess water, improves the density and strength of the concrete, and helps to reduce cracks caused by internal defects in the concrete. This method eliminates the traditional manual hand-held vibration method, greatly improves construction efficiency, and reduces the labor intensity of workers.
[0038] An installation structure 2 is installed on the outer surface of the pouring pipe 1. A support structure 3 is fixedly connected to the inner side of the installation structure 2. A connecting rod 4 is fixedly connected to one end of the support structure 3, and a driving structure 5 is fixedly connected to the end of the connecting rod 4 away from the support structure 3. The installation structure 2 includes a first connecting frame 21 and a scale 25. By setting the scale 25, the operator can accurately adjust the vibrator 6 to the required height according to the indication on the scale 25, thereby ensuring that each vibration operation achieves the best effect. Fixed arc plates 22 are fixedly connected to both sides of one end of the first connecting frame 21. A movable arc plate 23 is movably connected to one end of each fixed arc plate 22 through a rotating shaft. A fastening nut 24 is threaded between the fixed arc plate 22 and the movable arc plate 23. The scale 25 is set on the first connecting frame 21 away from the fixed arc plate. At one end of 22, both the movable arc plate 23 and the fixed arc plate 22 are interlaced and connected to the outer surface of the pouring pipe 1; the support structure 3 includes a limiting structure 31, a sliding block 32, a fixed block 33, a limiting frame 34, and a spring 35. The sliding block 32 is movably interlaced and connected to the outer surface of the limiting structure 31. The fixed block 33 is fixedly connected to one end of the outer surface of the sliding block 32. The limiting frame 34 is fixedly connected to the end of the fixed block 33 away from the sliding block 32. The spring 35 is sleeved on the outer surface of the limiting structure 31. The limiting structure 31 is fixedly connected between the two inner walls on the inner side of the first connecting frame 21; a vibrating rod 6 is movably interlaced and connected inside the driving structure 5. An installation plate 7 is fixedly interlaced and connected to the outer surface of the vibrating rod 6. A vibrating pipe 8 is fixedly connected to the top of the vibrating rod 6. A vibrator 9 is fixedly connected to the end of the vibrating pipe 8 away from the vibrating rod 6.
[0039] Depend on Figures 1 to 3 It is known that the limiting structure 31 includes a screw 311, a rotating column 312, a connecting ring 313, a support block 314, and a sliding frame 315. The rotating column 312 is threaded to one side of the outer surface of the screw 311. The connecting ring 313 is bearing-connected to the outer surface of the rotating column 312. The connecting ring 313 is connected to the rotating column 312 through the bearing, so that the connecting ring 313 will not rotate when the rotating column 312 is adjusted. The support block 314 is fixedly connected to the outer surface of one end of the connecting ring 313. The sliding frame 315 is fixedly connected to the end of the support block 314 away from the connecting ring 313. The screw 311 is fixedly connected between the two inner walls on the inner side of the first connecting frame 21.
[0040] As can be seen from the above, rotating the rotating column 312 causes it to shift on the outer surface of the screw 311, which in turn causes the connecting ring 313 to move downward. The connecting ring 313 causes the support block 314 to move downward, which in turn causes the sliding block 32 to move the fixed block 33 downward. The fixed block 33 causes the limiting frame 34 to slide outside the first connecting frame 21. As the sliding block 32 moves downward, it compresses the spring 35, causing the spring 35 to contract. When the limiting frame 34 moves, it causes the connecting rod 4 to move downward. The connecting rod 4 causes the driving structure 5 to move downward, which in turn causes the vibrating rod 6 to move. This allows the height of the vibrating rod 6 to be adjusted according to the mold, preventing the vibrating rod 6 from directly vibrating the joints of the template and reducing damage to the concrete surface caused by vibration.
[0041] Preferably, the limiting frame 34 is movably inserted into the outer surface of one end of the first connecting frame 21, and the spring 35 is fixedly connected between the sliding block 32 and the inner side of the mounting structure 2; the sliding frame 315 is slidably connected to the outer surface of the first connecting frame 21.
[0042] As can be seen from the above, the limiting frame 34 is inserted through the outer surface of the first connecting frame 21, thereby improving the stability of the sliding block 32 in raising and lowering. The sliding frame 315 is slidably connected to the outer surface of the first connecting frame 21 and has a through groove at one end. The scale 25 can be seen during the adjustment process, so the height of the vibration can be precisely controlled.
[0043] refer to Figure 6 As shown, the driving structure 5 includes a connecting seat 51, a second connecting frame 52, a connecting plate 53, and a pull rod 55. The second connecting frame 52 is fixedly connected to the outer surface of one end of the connecting seat 51. The connecting plate 53 is fixedly connected to the end of the second connecting frame 52 away from the connecting seat 51. Two fixing plates 54 are fixedly connected to one end of the connecting plate 53. The pull rod 55 is movably inserted between the two fixing plates 54 through a rotating shaft. The connecting seat 51 is movably inserted into the vibrator 6.
[0044] As can be seen from the above, pulling the tie rod 55 causes the two fixed plates 54 to move, the fixed plates 54 cause the connecting plate 53 to move downward, the connecting plate 53 causes the connecting seat 51 to move downward through the second connecting frame 52, the connecting seat 51 causes the vibrator 6 to move downward, and the vibrator 6 is inserted into the material. The vibrator 6 is used to vibrate the material, so that the aggregate and cement paste in the concrete are fully mixed, the internal air bubbles and excess water are removed, the density and strength of the concrete are improved, and cracks caused by internal defects in the concrete are reduced.
[0045] Preferably, the connecting seat 51 is installed together with the mounting plate 7; the second connecting frame 52 is configured as an arc-shaped structure; and the connecting rod 4 is fixedly connected between the limiting frame 34 and the connecting seat 51.
[0046] As can be seen from the above, installing the mounting plate 7 and the connecting seat 51 improves the stability of the vibrating rod 6 installation.
[0047] refer to Figure 1 and Figure 3 As shown, the first connecting frame 21 is configured as a U-shaped structure.
[0048] As can be seen from the above, firstly, the fixed arc plate 22 is inserted through the outer surface of the pouring pipe 1 to ensure that each piece is firmly attached. Then, by flexibly adjusting the position of the movable arc plate 23, one end of it is tightly attached to the fixed arc plate 22, forming a stable and adjustable clamp structure, which enhances the firmness of the installation. The movable arc plate 23 and the fixed arc plate 22 are locked with the fastening nut 24 to ensure that the entire installation structure 2 is firmly installed on the pouring pipe 1, forming an integrated moving unit. In this way, when the pouring pipe 1 moves during the pouring operation, it can naturally drive the vibrator 6 to move synchronously, eliminating the traditional manual hand-held vibration method, greatly improving construction efficiency, reducing the labor intensity of workers, ensuring the uniformity and compactness of concrete vibration, and further improving the quality of the project.
[0049] Furthermore, this invention is designed and applied in the process of casting fair-faced concrete production. The casting pipe 1 is installed on a gantry frame, and the fixed arc plates 22 are all inserted through the outer surface of the casting pipe 1. The movable arc plate 23 is pulled so that one end of the movable arc plate 23 is tightly attached to the fixed arc plate 22, and then fixed by the fastening nut 24, so that the mounting structure 2 is installed on the outer surface of the casting pipe 1. The vibrator 6 is inserted into the connecting seat 51, and the mounting plate 7 is installed together with the connecting seat 51, so that the device can be assembled. The rotating column 312 is rotated, and the rotating column 312 is displaced on the outer surface of the screw 311, driving the shaft of the screw 311 to move. The connecting ring 313 moves downward, causing the support block 314, which is fixedly connected to it, to move downward. The support block 314 slides on the outer surface of the first connecting frame 21. As the screw 311 moves downward, it pushes the sliding block 32, which is in close contact with it, to move downward. The sliding block 32 causes the fixed block 33, which is fixedly connected to it, to move downward. The fixed block 33 causes the limiting frame 34, which is fixedly connected to it, to slide outside the first connecting frame 21. As the sliding block 32 moves downward, it compresses the spring 35, causing the spring 35 to contract. When the limiting frame 34 moves, it causes the connecting rod 4, which is fixedly connected to it, to move downward. The connecting rod 4 drives the fixedly connected driving structure 5 to move downwards, which in turn drives the vibrating rod 6 to move, thereby adjusting the height of the vibrating rod 6 according to the mold. When the material is poured into the mold through the pouring pipe 1, the vibrator 9 is activated, causing the vibrating rod 6 to start and pull the pull rod 55. The pull rod 55 drives the two fixed plates 54 movably connected to it to move downwards. The fixed plates 54 drive the connecting plate 53 fixedly connected to them to move downwards. The connecting plate 53 drives the connecting seat 51 to move downwards through the second connecting frame 52 fixedly connected to it. The connecting seat 51 drives the vibrating rod 6 to move downwards, so that the vibrating rod 6 is inserted into the material. The concrete is vibrated by the vibrator 6, which fully mixes the aggregate and cement paste in the concrete, removes internal air bubbles and excess water, improves the density and strength of the concrete, and helps to reduce cracks caused by internal defects in the concrete. When the connecting seat 51 is displaced, it will drive the connecting rod 4 fixedly connected to it to move. The connecting rod 4 drives the limiting frame 34 to slide downward on the outer surface of the first connecting frame 21. At the same time, the limiting frame 34 drives the sliding block 32 to slide on the outer surface of the screw 311 through the fixing block 33, and squeezes the spring 35, causing the spring 35 to contract, so that the depth of the vibrator 6 inserted into the material can be precisely controlled.
[0050] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
