Description

Technical Field

[0001] This utility model relates to the field of building engineering equipment technology, specifically a vibration device for preventing cracks in concrete structural systems in building engineering. Background Technology

[0002] A concrete vibrator is a machine that uses vibration to compact concrete. Types include immersion vibrators, attached vibrators, plate vibrators, and vibrating tables for compacting precast concrete components. They are widely used on construction sites and in concrete product factories, such as in rural road construction. When pouring concrete from a concrete mixer into components, air bubbles must be removed and the concrete compacted to ensure a dense bond, eliminate honeycomb and pitting defects, improve strength, and guarantee the quality of the concrete components.

[0003] An existing patent for a concrete vibrator, patent number CN206016277U, includes an electric motor, a vibrating rod, and a flexible hose connecting the electric motor and the vibrating rod. The vibrating rod contains a circumferential vibration assembly, which includes a rotating shaft connected at one end to the flexible hose. The vibrating rod also contains an axial vibration assembly, which includes an impact part and a transmission part. The transmission part is located at the other end of the rotating shaft and, driven by the rotating shaft, the impact part performs axial reciprocating motion. The electric motor drives the flexible hose to rotate, which in turn drives the rotating shaft inside the vibrating rod to rotate. During the rotation of the rotating shaft, the circumferential vibration assembly causes the vibrating rod to vibrate circumferentially. Simultaneously, the rotation of the rotating shaft, through the transmission part, drives the impact part to generate an axial impact, which in turn causes the vibrating rod to vibrate axially. Thus, the entire vibrating rod produces a three-dimensional vibration pattern, enhancing both the vibration intensity and the range of vibration influence.

[0004] However, the vibrator in patent authorization number CN206016277U is manually operated during the vibration of concrete. This can easily lead to the vibrator being inserted obliquely into the concrete, resulting in uneven vibration or omission of certain areas, which can cause cracks in the concrete. Therefore, we propose a vibration device for preventing cracks in concrete structural systems in building engineering to solve the above-mentioned problems. Utility Model Content

[0005] The purpose of this utility model is to provide a vibration device for preventing cracks in concrete structural systems in building engineering, so as to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A vibration device for preventing cracks in concrete structural systems in building engineering includes an electric motor, a flexible hose connected to the power output end of the electric motor, and a vibrating rod connected to the flexible hose. The outer wall of the vibrating rod is provided with graduation lines in the axial direction.

[0008] The vibrating rod is fitted with an external threaded sleeve on its outer side. The end of the external threaded sleeve is integrally formed with a claw, and multiple claws are arranged in the radial position of the external threaded sleeve. The end of the claw is integrally formed with an inclined surface away from the surface of the vibrating rod.

[0009] The outer threaded sleeve is connected to the inner threaded sleeve by a threaded connection. A float plate is installed at the end of the outer wall of the inner threaded sleeve. A limiting flange is integrally formed on the inner side of the end of the inner threaded sleeve near the float plate, and the inner diameter of the limiting flange is smaller than the outer diameter of the outer threaded sleeve.

[0010] In a preferred embodiment of this utility model, a timer is installed at the end of the hose closest to the motor.

[0011] In a preferred embodiment of this utility model, three claws are specifically provided, and the included angle between the corresponding external threaded sleeve axis lines of two adjacent claws is 120°.

[0012] In a preferred embodiment of this utility model, the surface of the claw end near the vibrator is integrally formed with protruding teeth.

[0013] In a preferred embodiment of this utility model, the float is made of PVC material, and the inner side of the float has a hollow structure.

[0014] In a preferred embodiment of this utility model, the outer wall of the external threaded sleeve is provided with anti-slip texture.

[0015] In a preferred embodiment of this utility model, both the external threaded sleeve and the internal threaded sleeve are made of polyamide.

[0016] Additional aspects and advantages of this invention will be set forth in part in the description which follows, and in part will be obvious from the description, or may be learned by practice of the invention.

[0017] Adjust the external threaded sleeve to the appropriate position of the vibrator according to the concrete pouring depth and the scale line. Then insert the vibrator into the concrete, so that the bottom end of the vibrator abuts against the base layer. Make the insertion depth of the vibrator match the pouring depth of the concrete. At the same time, make the float plate float on the surface of the concrete to prevent the vibrator from tilting. This can ensure that the effective action of the vibrator can be directly applied to the concrete, avoiding uneven vibration or omission of some areas due to tilting insertion, thereby preventing cracks from appearing in the concrete after it has set.

[0018] During the concrete vibration process, a timer should be used to keep track of the vibration time at each insertion point. The vibration time should be controlled between - and - seconds. If the vibration time is too short, the concrete may not be sufficiently compacted, while if the time is too long, the concrete may segregate. Vibration should continue until the concrete surface shows a layer of slurry, no longer sinks, and no more air bubbles emerge. This can also prevent cracks from appearing in the concrete after it has set. Attached Figure Description

[0025] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.

[0026] Please refer to Figure 1-4 A vibration device for preventing cracks in concrete structure systems in building engineering includes an electric motor 1, a flexible hose 2 connected to the power output end of the electric motor 1, and a vibrating rod 3 connected to the flexible hose 2. The outer wall of the vibrating rod 3 is provided with scale lines 4 in the axial direction.

[0027] The vibrating rod 3 is fitted with an external threaded sleeve 5 on its outer side. The end of the external threaded sleeve 5 is integrally formed with a claw 6, and multiple claws 6 are arranged in the radial position of the external threaded sleeve 5. The end of the claw 6 is integrally formed with an inclined surface 7 on the surface away from the vibrating rod 3.

[0028] The outer threaded sleeve 5 is threadedly connected to the inner threaded sleeve 8. A float plate 9 is installed at the end of the outer wall of the inner threaded sleeve 8. A limiting flange 10 is integrally formed on the inner side of the end of the inner threaded sleeve 8 near the float plate 9, and the inner diameter of the limiting flange 10 is smaller than the outer diameter of the outer threaded sleeve 5.

[0029] When using the concrete structure crack prevention vibratory compaction device in this construction project, the pouring depth of the concrete is first measured. Then, the external threaded sleeve 5 and the internal threaded sleeve 8 are fitted onto the vibratory rod 3. The external threaded sleeve 5 is then adjusted to the appropriate position according to the position of the scale line 4. By screwing the internal threaded sleeve 8, its end contacts the inclined surface 7, causing the claw 6 to retract and hold the vibratory rod 3 tightly. At the same time, the reverse force of the claw 6 can effectively prevent the internal threaded sleeve 8 from loosening. Then, the vibratory rod 3 is inserted into the concrete, so that the bottom end of the vibratory rod 3 abuts against the base layer, and the insertion depth of the vibratory rod 3 is matched with the pouring depth of the concrete. At the same time, the floating plate 9 floats on the surface of the concrete to prevent the vibratory rod 3 from tilting. This ensures that the effective action of the vibratory rod 3 can be directly applied to the concrete, avoiding uneven vibration or omission of certain areas due to tilted insertion, thereby preventing cracks from appearing in the concrete after later setting.

[0030] A timer 11 is installed at one end of the hose 2 near the motor 1. During the concrete vibration process, the timer 11 is used to keep track of the vibration time at each insertion point. The vibration time should be controlled between 20 and 30 seconds. If the vibration time is too short, the concrete may not be sufficiently compacted, while if the time is too long, the concrete may segregate. Vibration should continue until the concrete surface shows a slurry, no longer sinks, and no more air bubbles emerge. This can also prevent cracks from appearing in the concrete after it has set.

[0031] Specifically, three jaws 6 are provided, and the included angle between the corresponding external threaded sleeve 5 axis lines between two adjacent jaws 6 is 120°.

[0032] The end of the claw 6 has protruding teeth integrally formed on the surface near the vibrating rod 3; the float 9 is made of PVC and the inner side of the float 9 is hollow; the outer wall of the external threaded sleeve 5 is provided with anti-slip texture; both the external threaded sleeve 5 and the internal threaded sleeve 8 are made of polyamide.

[0033] During the clamping process of the claw 6, the protruding teeth are tightly attached to the outer wall of the vibrator 3, so that the external threaded sleeve 5 can be stably fixed at the vibrator 3; the float plate 9 floats horizontally on the surface of the concrete to prevent the vibrator 3 from tilting, which can ensure that the effective action of the vibrator 3 can be directly applied to the concrete.

[0034] The working principle of this utility model is as follows: First, the pouring depth of the concrete is measured. Then, the external threaded sleeve 5 and the internal threaded sleeve 8 are fitted together onto the vibrator 3. Then, the external threaded sleeve 5 is adjusted to a suitable position according to the position of the scale line 4. By screwing the internal threaded sleeve 8, its end contacts the inclined surface 7, causing the claw 6 to retract and hold the vibrator 3 tightly. At the same time, the reverse force of the claw 6 can effectively prevent the internal threaded sleeve 8 from loosening. Then, the vibrator 3 is inserted into the concrete, so that the bottom end of the vibrator 3 abuts against the base layer, and the insertion depth of the vibrator 3 is matched with the pouring depth of the concrete. At the same time, the floating plate 9 floats on the surface of the concrete to prevent the vibrator 3 from tilting, which can ensure that the effective action of the vibrator 3 can be directly applied to the concrete.

[0035] Although embodiments of the present invention have been shown and described, those skilled in the art will understand that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the claims and their equivalents.
