Description

Technical Field

[0001] The utility model belongs to the technical field of building engineering construction, in particular to a concrete plate vibrator for building construction. Background Art

[0002] Concrete is an important construction material in construction projects and the foundation for the construction of various buildings. The construction quality of concrete has a huge impact on the stability and aesthetics of the building structure. The flat plate vibrator can improve the density of concrete during paving and perform preliminary leveling and compaction of the concrete surface layer. When the flat plate vibrator is working, the vibration force forces the concrete to vibrate, causing the accumulation state of the cement mortar to change from loose to dense, thereby improving the construction quality.

[0003] The existing flat plate vibrator combines a vibration motor with a leveling ruler to achieve the functions of leveling and compaction. However, in actual application, the construction area of ​​concrete is often different. When the construction area is large, the small-sized leveling ruler reduces the construction efficiency; when the construction area is small, the large-sized leveling ruler increases the difficulty of construction. In addition, during the construction process, workers need to hold the flat plate vibrator for a long time, which increases the risk of construction workers suffering from hand-arm vibration disease.

[0025] like Figure 1 , Figure 2As shown, a fixing device 9 for fixing the end of the folding ruler 6 close to the vibrating motor 7 is provided. Through the fixing device 9, the folding ruler 6 can be stored above the vibrating ruler main board 5-1.

[0026] like Figure 2 , Figure 3 As shown, the fixing device 9 includes a fixing seat 9-1 with a socket, the fixing seat 9-1 is installed on one end of the folding ruler 6 close to the vibrating motor 7, the vibrating ruler main board 5-1 is provided with a support 9-2 with a socket matched with the fixing seat 9-1, and the sockets of the fixing seat 9-1 and the support 9-2 can be inserted with a pin 9-3 with a ring handle 9-4, a pair of positioning columns 9-5 are provided on the vibrating ruler main board 5-1 on both sides of the ring handle 9-4, and the vibrating ruler main board 5-1 is also provided with a buckle 9-6 for fixing the ring handle 9-4.

[0027] like Figure 4 , Figure 5 As shown, the first groove 10 and the second groove 11 are provided on both sides where the vibrating ruler main board 5-1 and the folding ruler 6 are connected, and the first groove 10 and the second groove 11 are provided with a limit frame 12. The first groove 10 and the second groove 11 are connected to form a slide rail 13, and a movable sliding steel plate 14 is provided in the slide rail 13. The length of the sliding steel plate 14 is less than or equal to the length of the first groove 10 of the vibrating ruler main board 5-1, and the sliding steel plate 14 can be received in the first groove 10 of the vibrating ruler main board 5-1.

[0028] The limit frame 12 in this embodiment is used to ensure that the sliding steel plate 14 does not move in the slide rail 13. The rigid sliding steel plate 14 ensures the consistency of vibration of the vibrating ruler main board 5-1 and the folding ruler 6, ensuring that the folding ruler 6 can achieve the initial leveling function synchronously with the vibrating ruler main board 5-1 after being opened.

[0029] like Figure 6 As shown, the spring shock absorber 3 includes an upper sleeve 3-1 and a lower sleeve 3-2, the outer diameter of the upper sleeve 3-1 and the inner diameter of the lower sleeve 3-2 are matched and installed, and a shock absorbing spring 3-4 is installed inside the upper sleeve 3-1 and the lower sleeve 3-2, and the top of the upper sleeve 3-1 and the bottom of the lower sleeve 3-2 are both equipped with anti-slip rubber 3-3, and the top of the upper sleeve 3-1 and the bottom of the lower sleeve 3-2 are also provided with internal threads 3-5 that are compatible with the first connecting rod 2-1 and the second connecting rod 2-2. The top and bottom of the spring shock absorber 3 are both provided with internal threads 3-5, which are precisely matched with the external threads of the first connecting rod 2-1 and the second connecting rod 2-2, and then tightened by nuts, thereby ensuring the stability and reliability of the connection.

[0031] like Figure 1 , Figure 4 As shown, both sides of the second connecting rod 2-2 are connected to the upper ends of a pair of diagonal bracing rods 4, and the lower ends of the diagonal bracing rods 4 are fixedly connected to the mounting vertical plate 5-2, thereby improving the stability of the equipment.

[0032] The working principle of the utility model is:

[0033] After the vibrating motor 7 installed on the vibrating ruler main board 5-1 is powered on and started, its own vibration will drive the vibrating ruler main board 5-1 to vibrate synchronously. The first connecting rod 2-1 and the second connecting rod 2-2 are respectively connected to the faucet handle 1 and the mounting vertical plate 5-2. When working, the worker can adjust the working area by holding the faucet handle 1 and moving it. The spring shock absorber 3 connected to the first connecting rod 2-1 and the second connecting rod 2-2 eliminates the vibration of the mechanical structure through the shock-absorbing spring 3-4 and the anti-slip rubber 3-3. A vibration-damping air cushion is also provided on the faucet handle 1 to further weaken the vibration transmitted to the worker's hands.

[0034] When the construction area is small, the worker will store the folding ruler 6 above the vibrating ruler main board 5-1. When the folding ruler 6 is completely close to the vibrating ruler main board 5-1, the pin 9-3 can be inserted into the support 9-2 on the vibrating ruler main board 5-1 and the fixed seat 9-1 on the folding ruler 6 in turn. When fully inserted, the annular handle 9-4 of the pin 9-3 is just restricted within a pair of positioning columns 9-5, and the buckle 9-6 is fastened to start the operation.

[0035] When the construction area is large, the worker opens the folding ruler 6 to both sides of the vibrating ruler main board 5-1. When the folding ruler 6 is fully unfolded, the first groove 10 of the vibrating ruler main board 5-1 and the second groove 11 of the folding ruler 6 together form a slide rail 13. At this time, the sliding steel plate 14 originally accommodated in the first groove 10 of the vibrating ruler main board 5-1 can be moved out along the slide rail 13. In order to ensure the stability and accuracy of the sliding steel plate 14 during movement, its position is limited by the limit frame 12 installed on the vibrating ruler main board 5-1 and the folding ruler 6. Once the sliding steel plate 14 is correctly positioned and fixed, the operation can begin. The unfolded folding ruler 6 exhibits excellent rigidity and flatness during the operation, ensuring the accuracy and efficiency of the operation.
