Concrete aluminum form external vibrating device

Abstract

This invention discloses an external vibratory compaction device for aluminum formwork concrete, relating to the technical field of concrete vibration. Its key technical features include: a guiding mechanism with a mounting seat slidably mounted on it; a vibrator mounted on the mounting seat; the vibration force of the vibrator is transmitted to the aluminum formwork through the guiding mechanism; and the movable mounting seat changes the vibration center of the vibrator acting on the aluminum formwork. The vibrator is slidably mounted outside the aluminum formwork via the mounting seat and guiding mechanism, allowing the vibration force to directly compact the concrete surface. This results in less air bubbles appearing on the surface of the concrete poured using the aluminum formwork after vibration, improving both the aesthetics and strength of the structure. Furthermore, during vibration, the mounting seat can slide along the guiding mechanism to adjust its relative position to the aluminum formwork, thereby changing the vibration center of the vibrator and ensuring more uniform compaction of the concrete surface, preventing poor compaction of concrete surfaces far from the vibrator.

Description

Technical Field

[0001] This invention relates to the technical field of concrete vibration, specifically to an external vibration device for concrete aluminum molds. Background Technology

[0002] Aluminum formwork construction is a new type of construction method with advantages such as light weight, easy assembly and disassembly, high rigidity, high precision, good stability, high load-bearing capacity, good concrete forming quality, high reusability, and safe and civilized construction. It is increasingly being accepted and used by construction companies. However, because the construction method of aluminum formwork differs from traditional formwork, many technological problems have arisen during actual construction.

[0003] During the concrete forming process, air bubbles often form on the concrete surface due to various factors such as materials, processes, and environmental conditions. Excessive air bubbles reduce the end-face volume of the concrete, resulting in a less dense interior and reduced strength. Simultaneously, a large number of air bubbles reduces the effective thickness of the reinforcing steel cover, accelerating the carbonation process on the concrete surface. Furthermore, a large number of air bubbles also negatively impacts the appearance of the concrete. Traditional vibration methods typically involve inserting a vibrator into the concrete, which effectively removes air bubbles inside the concrete but is less effective at removing air bubbles from the surface. Using a handheld vibrator, constantly moving it outside the aluminum mold, leads to worker fatigue over time, reducing the efficiency and effectiveness of the vibration process. Summary of the Invention

[0004] In view of the shortcomings of the existing technology, the purpose of this invention is to provide an external vibratory compaction device for aluminum formwork concrete. Its advantages are: the vibrator is slidably set on the outside of the aluminum formwork through the mounting base and guide mechanism, so the vibration force of the vibrator can directly vibrate the surface of the concrete, thereby making it less likely for air bubbles to appear on the surface of the concrete building poured by the aluminum formwork after vibration by this invention, and improving the aesthetics and strength of the building.

[0005] The above-mentioned objective of the present invention is achieved through the following technical solution:

[0006] An external vibratory compaction device for aluminum concrete formwork includes a guiding mechanism, which is disposed outside the aluminum formwork. A mounting base is slidably connected to the guiding mechanism, and a vibrator is disposed on the mounting base. The vibration force of the vibrator is transmitted to the aluminum formwork through the guiding mechanism.

[0007] In a preferred embodiment, the present invention can be further configured such that: the guiding mechanism includes two parallel slide rails, the mounting base includes a mounting plate and guide plates disposed on both sides of the mounting plate, and the two guide plates are slidably connected in two slide grooves respectively.

[0008] In a preferred embodiment, the present invention can be further configured such that: the mounting plate is slidably connected to the guide plate via a guide rod, the guide rod is sleeved with a spring, one end of the spring abuts against the mounting plate, and the other end of the spring abuts against the guide plate.

[0009] In a preferred embodiment, the present invention may be further configured such that: a mounting rod is provided between the two guide plates, a drive wheel is rotatably mounted on the mounting rod, the drive wheel abuts against the slide rail, and a drive assembly is provided between the mounting plate and the mounting rod, the drive assembly being able to drive the drive wheel to rotate.

[0010] In a preferred embodiment, the present invention can be further configured as follows: the driving assembly includes a first driving cylinder disposed at the end face of the mounting plate and a second driving cylinder disposed on the mounting rod. The first driving cylinder is inserted into the second driving cylinder. An elastic element is disposed inside the first driving cylinder. A driving rod is rotatably disposed inside the second driving cylinder. The inner diameter of the first driving cylinder is larger than the outer diameter of the driving rod. The elastic element abuts against the driving rod. The driving rod includes two driving parts along the axial direction. The two driving parts are provided with helical driving grooves in opposite directions. Two driving claws are elastically disposed on the inner wall of the first driving cylinder. The two driving claws are respectively opposite to the two driving parts and extend into the corresponding helical driving grooves.

[0011] In a preferred embodiment, the present invention can be further configured such that the drive wheels are a pair and symmetrically arranged, and the drive rod drives the drive wheels to rotate through a transmission assembly.

[0012] In a preferred embodiment, the present invention may be further configured such that the transmission assembly includes a first gear sleeved on the drive rod and a second gear sleeved on the drive wheel, wherein the first gear and the second gear mesh.

[0013] In a preferred embodiment, the present invention can be further configured such that: a third gear is also connected between the second gear and the first gear; the drive wheel can also spring along the axial direction when rotating; an annular guide groove is provided on the side wall of the slide rail; one of the annular guide grooves has an upwardly inclined first guide portion at one end of the slide rail; the other annular guide groove has a corresponding second guide portion; the shaft of the drive wheel includes a spring-like portion and a rotating portion; the rotating portion is rotatably connected to the spring-like portion; the second gear is sleeved on the rotating portion; a guide rod is provided on the spring-like portion; the guide rod is inserted into the annular guide groove; and the two guide rods always remain vertically misaligned.

[0014] In summary, the present invention has at least one of the following beneficial technical effects:

[0015] 1. The vibrator is slidably set on the outside of the aluminum formwork through the mounting base and guide mechanism. Therefore, the vibration force of the vibrator can directly vibrate the surface of the concrete, so that the concrete surface of the aluminum formwork after vibration by the present invention is less likely to have air bubbles, and the aesthetics and strength of the building are improved.

[0016] 2. During the vibration process, the mounting base can slide along the guide mechanism to adjust its relative position with the aluminum template, thereby changing the vibration center of the vibrator, making the vibrator vibrate the concrete surface more evenly, and preventing the concrete surface far from the vibrator from being poorly vibrated.

[0017] 3. Through the cooperation of the drive assembly, two drive wheels, and transmission assembly, the vibrator can achieve automatic reciprocating vibration operation. Furthermore, under the transmission of the drive assembly, the reciprocating motion of the mounting base fully utilizes the original vibration force of the vibrator as the driving force, making the vibrating device of this invention more environmentally friendly and energy-saving, and suitable for widespread use in building construction.

[0024] The present invention will be further described in detail below with reference to the accompanying drawings.

[0025] like Figures 1 to 5 As shown, this invention discloses an external vibratory compaction device for aluminum formwork concrete. It includes a guide mechanism 1, which is disposed outside the aluminum formwork. A mounting base 2 is slidably connected to the guide mechanism 1, and a vibrator 3 is mounted on the mounting base 2. The vibration force of the vibrator 3 is transmitted to the aluminum formwork through the guide mechanism 1. Here, the guide mechanism 1 spans across a wall panel constructed from multiple aluminum formworks. Furthermore, it is preferable to position the guide mechanism 1 in the middle of the wall panel. In this way, the vibration force from the vibrator 3 can be transmitted relatively directly to the concrete surface through the guide mechanism 1 and the aluminum formwork, and air bubbles adhering between the concrete and the aluminum formwork can be expected to be expelled.

[0026] This can be understood as the movable mounting base 2 changing the relative position between the vibrator 3 and the aluminum mold, thus altering the vibration center of the vibrator 3. In a fixed vibrator 3, the vibration force gradually weakens from the center outwards, potentially leading to insufficient vibration and excessive air bubbles on the concrete surface furthest from the vibrator 3. However, when the vibrator 3 is movable, timely movement of the vibrator 3 ensures thorough and uniform vibration of the entire concrete surface corresponding to the wall panel.

[0027] The vibrator 3 is preferably an eccentric motor. The guide mechanism 1 includes two parallel slide rails 4, and the mounting base 2 includes a mounting plate 5 and guide plates 6 disposed on both sides of the mounting plate 5. The two guide plates 6 are respectively fitted into the two slide rails 4, so that the mounting base 2 can slide smoothly along the slide rails 4. In actual construction, screw holes can be pre-drilled on the outside of the aluminum formwork, and the slide rails 4 can be installed on the aluminum formwork by screws or other fasteners.

[0028] The guide plate 6 and the slide rail 4 are connected by a dovetail tenon joint. Figure 2In this case, the end of the guide plate 6 is provided with a T-shaped block, and a T-shaped groove is opened in the slide rail 4. Through the engagement of the T-shaped dovetail, the mounting base 2 can not only slide smoothly along the slide rail 4, but the load-bearing strength between the mounting base 2 and the slide rail 4 is also correspondingly improved.

[0029] Preferably, the vibrator 3 is installed on the outward-facing end face of the mounting plate 5. This allows the vibrator 3 to apply a relatively vertical vibration force to the aluminum mold, resulting in a more uniform vibration effect. To prevent excessive rigidity between the mounting seats 2, the mounting plate 5 is slidably connected to the guide plate 6 via a guide rod 7. The diagram shows the guide rod 7 installed on the end face of the mounting plate 5 facing away from the vibrator 3. A corresponding guide hole is provided on the guide plate 6, into which the guide rod 7 is inserted, allowing the mounting plate 5 and the guide plate 6 to slide relative to each other. Furthermore, a spring 8 is fitted over the guide rod 7. One end of the spring 8 abuts against the mounting plate 5, and the other end abuts against the guide plate 6. Thus, when the vibrator 3 vibrates, the mounting plate 5, under the action of the vibration force, presses the spring 8 between the mounting plate 5 and the guide plate 6. Understandably, this not only avoids excessive rigidity of the mounting base 2 and buffers and relieves the force of the rigid connection through the spring 8, but also the spring 8 plays a certain role in noise reduction, making the vibratory device disclosed herein more environmentally friendly.

[0030] Due to the potential reaction between the aluminum formwork and the concrete surface, air bubbles continuously adhere to the concrete surface during the pouring process. Therefore, continuous vibration of the exterior of the aluminum formwork is necessary to minimize bubble formation. This implies that the vibrating device disclosed herein needs to be constantly moved to vibrate the exterior of the aluminum formwork. However, if a common motor-driven mechanism were used, these mechanisms would experience reduced service life or malfunctions under the long-term vibration of the vibrator 3.

[0031] Therefore, a mounting rod 9 is provided between the two guide plates 6, and a drive wheel 10 is rotatably mounted on the mounting rod 9. The drive wheel 10 abuts against the slide rail 4. A drive assembly 11 is provided between the mounting plate 5 and the mounting rod 9, and the drive assembly 11 can drive the drive wheel 10 to rotate. The drive assembly 11 can convert the axial force generated when the mounting plate 5 vibrates into rotational force. With the drive wheel 10 abutting between the two slide rails 4, the rotational force of the drive assembly 11 is used to drive the rotational power of the drive wheel 10, thereby driving the entire mounting base 2 to move along the slide rail 4.

[0032] Under the guidance of the guide rod 7, the vibration force of the vibrator 3 will be converted into a part of the regularity of the mounting plate 5, that is, the mounting plate 5 can provide a constant linear driving force for the drive assembly 11.

[0033] like Figure 2 , Figure 3 As shown, the drive assembly 11 includes a first drive cylinder 12 disposed at the end face of the mounting plate 5 and a second drive cylinder 13 disposed on the mounting rod 9. The first drive cylinder 12 is coaxially inserted into the second drive cylinder 13, and the first drive cylinder 12 is located at the end face of the mounting plate 5 opposite to the vibrator 3. An elastic element 14 is disposed inside the first drive cylinder 12, and a drive rod 15 is rotatably disposed inside the second drive cylinder 13. The inner diameter of the first drive cylinder 12 is larger than the outer diameter of the drive rod 15, and the elastic element 14 abuts against the drive rod 15. The elastic element 14 here is as follows: Figure 2 The image shows spring 8.

[0034] The drive rod 15 includes two drive sections 16 along the axial direction. Each drive section 16 has several helical drive grooves 17 circumferentially formed, and the helical drive grooves 17 on the two drive sections 16 are arranged in opposite directions. The inner wall of the first drive cylinder 12 is provided with two drive claws 18, which correspond to the two drive sections 16 respectively, and the drive claws 18 extend into the helical drive grooves 17 of the corresponding drive sections 16.

[0035] As the first drive cylinder 12 moves axially towards the mounting rod 9, the drive claw 18 closer to the mounting rod 9 will push the corresponding spiral drive groove 17, causing the drive rod 15 to rotate. At this time, the other drive claw 18 will bounce, exhibiting a state of continuously passing through several drive grooves on the corresponding drive part 16. When the first drive cylinder 12 returns to its original position away from the mounting rod 9, the usage states of the two drive claws 18 switch with each other, thereby converting the reciprocating bounce of the second drive cylinder 13 into the unidirectional rotation of the drive rod 15.

[0036] The two coaxially arranged drive units 16, in conjunction with the two drive claws 18, offer a smaller stroke and higher response accuracy, making them more suitable for applications using the vibration force of a vibrator as the driving force. Within the small spring-like range of the mounting plate 5, both drive units 16 can respond, thereby driving the mounting base 2 to move stably and reliably. In the above solution, the spring-like range of the first drive cylinder 12 needs to be sufficient to drive the drive column into the inflection point of the V-shaped drive groove, which places certain requirements on the accuracy of the spring-like range of the mounting plate 5. Clearly, in the preferred case where the spiral drive grooves 17 are sufficiently dense in the drive assembly 11 shown in this solution, the small spring-like range of the mounting plate 5 can still stably drive the mounting base 2 to move.

[0037] Preferably, there are two drive wheels 10 facing each other on the left and right, and the drive rod 15 drives the two drive wheels 10 to rotate through the transmission assembly 19. The arrangement of the two drive wheels 10 will make the movement of the mounting base 2 more stable and reliable. The transmission assembly 19 includes a first gear 20 sleeved on the drive rod 15 and a second gear 21 sleeved on the rotating shaft of the two drive wheels 10, and the first gear 21 meshes with the second gear 21.

[0038] See appendix Figure 2 One of the second gears 21 is connected to the first gear 20 by a third gear 22, meaning that a third gear 22 is rotatably mounted between the shaft of the drive wheel 10 on the left side of the mounting plate 5 and the drive rod 15. The third gear 22 is also engaged between the second gear 21 and the first gear 20 on the left side. Thus, assuming all four gears mesh simultaneously, due to the reversal of the third gear 22's transmission, the drive wheel 10 on the left side will have a rotation direction opposite to that of the drive wheel 10 on the right side. In other words, by controlling the engagement and disengagement of the second gear 21 and the third gear 22 on the left side, and by controlling the engagement and disengagement of the second gear 21 and the first gear 20 on the right side, the two drive wheels 10 with opposite rotation directions can be switched to act as driving forces individually, thereby achieving the reversing movement of the mounting base 2.

[0039] like Figure 2 As shown, the drive wheel 10 can also spring along the axial direction when rotating. The shaft of the drive wheel 10 includes a springing part 27 and a rotating part 28. The rotating part 28 is rotatably connected to the springing part 27, and the second gear 21 is sleeved on the rotating part 28. The springing part 27 can be connected to the mounting rod 9 by a spring 8, thereby realizing the overall springing of the shaft. For example, after the shaft springs as a whole, it can drive the disengagement or engagement of the two gears.

[0040] like Figure 4 , Figure 5 As shown, to achieve automatic reversing of the mounting base 2, annular guide grooves 23 are provided on the opposite sidewalls of both slide rails 4. For ease of description, the slide rail on the left in the attached figure will be referred to as the first slide rail 4, and the slide rail on the right will be referred to as the second slide rail 4. Specifically, the annular guide groove 23 on the first slide rail 4 is located at the first end of the slide rail 4 (see attached figure). Figure 1 The right end of the middle slide rail has an upwardly inclined first guide portion 24; the annular guide groove 23 on the second slide rail 4 is located at the second end of the slide rail 4 (attached). Figure 1 The right end of the middle slide rail has an upwardly inclined second guide portion 25. In addition, a guide rod 26 is provided on the side wall of the spring part 27, which is adapted to the corresponding annular guide groove 23.

[0041] The two guide rods 26 always remain vertically offset, attached Figure 2When the left guide rod 26 is fitted into the upper channel of the corresponding annular guide groove 23, the right guide rod 26 is fitted into the lower channel of the corresponding annular guide groove 23.

[0042] Appendix Figure 2 When the left guide rod 26 is fitted into the upper channel of the corresponding annular guide groove 23, the left second gear 21 disengages from the third gear 22. Simultaneously, the right second gear 21 engages with the first gear 20, and then the mounting base 2 moves from one end to the other. As the right guide rod 26 continuously enters the second guide portion 25, the right second gear 21 gradually disengages from the first gear 20. At the same time, the left guide rod 26, under the action of elastic force, quickly enters the lower channel of the corresponding annular guide groove 23, and the left second gear 21 re-engages with the third gear 22, after which the mounting base 2 moves in the opposite direction. The movement process of the left guide rod and the first guide portion is similar to that of the right guide rod and the second guide portion, and therefore will not be described again.

[0043] In summary, the automatic reciprocating vibration operation of the vibrator 3 can be achieved through the cooperation of the drive component, two drive wheels and transmission component, so that the surface of the vibrated concrete is less prone to air bubbles.

[0044] The embodiments described herein are preferred embodiments of the present invention and are not intended to limit the scope of protection of the present invention. Therefore, all equivalent changes made in accordance with the structure, shape, and principle of the present invention should be covered within the scope of protection of the present invention.
