Description

Technical Field

[0001] The invention belongs to the technical field of chamber sealing tools, and in particular relates to a chamber sealing tool for grouting sleeves of assembled shear walls. Background Art

[0002] Prefabricated concrete structure is a concrete structure which takes prefabricated components as the main load-bearing components and is assembled and connected. The installation and splicing process of prefabricated shear wall is the process of connecting the embedded steel bars and embedded sleeves at the ends of the two wall panels to each other, and then connecting the two by on-site grouting. Before the above-mentioned grouting operation, since a 20mm splicing gap is required between the wall panels, it is necessary to fill the splicing gap with sealing mortar, so that the inside of the wall panel is isolated from the external environment. In this way, when the subsequent grouting is carried out, there will be no problem of slurry leakage along the splicing gap.

[0003] At present, the traditional treatment of the silo surface is carried out with a cement trowel as a tool. Since the silo surface is treated manually with a cement trowel, if the construction workers are not skilled, the mortar layer will be unevenly thick when the trowel is used to apply the mortar. The mortar in the excessively thick part is difficult to compact and voids are easily formed inside, while the excessively thin part cannot be fully filled, which directly affects the overall density. In addition, the trowel is mainly used for smearing and preliminary leveling, and it does not have a strong compaction function. If the construction workers simply apply the mortar on the silo surface with a trowel, the air in the mortar cannot be fully discharged, which will lead to insufficient density. Insufficient mortar density will cause gaps between the mortar and the base layer, forming hollows, which will reduce the bonding strength between the mortar and the base surface.

[0039] The PLC controller 7 is fixedly installed inside the scraping mechanism 1, and is electrically connected to the deflection support mechanism 2, the mortar density automatic detection and warning mechanism 3, the limit locking mechanism 4, the vibration tamping mechanism 5 and the tamping strength adjustment mechanism 6 respectively;

[0040] The battery pack 8 is fixedly installed in the scraping mechanism 1 and is used to supply power to the electronic mechanism.

[0041] The operating principle of the present invention is described as follows: the staff holds the handle 12 and uses the scraping plate 11 to scrape and smooth the sealing mortar filled between the two wall panels. During the scraping process, the ultrasonic detector 31 emits ultrasonic waves to the position of the sealing mortar after scraping. The ultrasonic detector 31 has an ultrasonic transmitting probe and a receiving probe. The transmitting probe emits ultrasonic waves into the sealing mortar. The ultrasonic waves propagate inside the structure and are reflected when encountering a loose area of ​​the sealing mortar. The receiving probe receives the reflected ultrasonic signal and infers the density of the sealing mortar by analyzing the propagation time of the reflected wave. Specifically, the receiving probe receives the reflected ultrasonic wave. The PLC controller 7 calculates the propagation time of the ultrasonic wave from emission to reception through the internal calculation and analysis module, which is recorded as t. The thickness L of the mortar structure is known, and the propagation speed v of the ultrasonic wave in the mortar is calculated according to the formula v=2L / t. The 2L here is because the ultrasonic wave travels a round trip from emission to reception. The higher the density of the mortar, the more uniform its internal structure and the fewer pores, and the faster the ultrasonic wave propagates in it; on the contrary, the lower the density of the mortar, the slower the ultrasonic wave propagation speed. The density of the mortar can be confirmed by calculating the ultrasonic wave propagation speed.

[0042] When the propagation speed of the ultrasonic wave in the sealing mortar is lower than the threshold value, the PLC controller 7 controls the alarm 32 to sound to remind the staff. At this time, the staff suspends the continued movement of the scraping plate 11, and the PLC controller 7 controls the electric telescopic rod 51 to push the tamping plate 54 to move gradually. In this process, the PLC controller 7 controls the servo motor 63 to operate. The servo motor 63 drives the conductive block 67 to rotate and move continuously in the control shell 61 through the rotating shaft 62 and the extension rod 66. When the conductive block 67 contacts the forward electrical connection block 64, the forward power supply circuit of the force electromagnetic plate 58 is connected. The force electromagnetic plate 58 is energized to generate the same magnetism as the force permanent magnet plate 57, thereby driving the reciprocating plate 55 and the reciprocating rod 53 to drive the tamping plate 54 to move toward the sealing mortar. When the conductive block 67 contacts the reverse electrical connection block 65, the reverse power supply circuit of the force electromagnetic plate 58 is connected, thereby making the force The force electromagnetic plate 58 is energized to generate a magnetism opposite to that of the force-bearing permanent magnetic plate 57, thereby driving the tamping plate 54 to move back. In the process that the conductive block 67 is constantly in contact with the forward electrical connection block 64 and the reverse electrical connection block 65, the tamping plate 54 is constantly moving back and forth, providing a vibrating force to the sealing mortar, thereby filling the sealing mortar densely, and the electric telescopic rod 51 continuously pushes the tamping plate 54 to continuously squeeze and fill the sealing mortar densely, and the PLC controller 7 automatically adjusts the moving stroke of the electric telescopic rod 51 and the working power of the servo motor 63 based on the sealing mortar density information fed back by the mortar density automatic detection and warning mechanism 3. Specifically, the smaller the detected density of the sealing mortar, the larger the moving stroke of the electric telescopic rod 51, and the higher the working power of the servo motor 63, so that the vibration intensity of the tamping plate 54 is greater, ensuring that the sealing mortar is densely filled, and the vibration process lasts for 10 seconds;

[0043] The PLC controller 7 then controls the electric push rod 41 to cooperate with the connecting seat 42 to drive the limit frame 43 to move downward, so that the limit frame 43 is separated from the limit connection with the support plate 22. The PLC controller 7 then controls the deflection motor 21 to drive the support plate 22 to deflect, so that the vibration tamping mechanism 5 moves to the position of one of the wall panels. The PLC controller 7 then controls the vibration tamping mechanism 5 to operate, so that the mortar adhered to the tamping plate 54 is printed on one side of the wall panel, and the sealing mortar with density problems is marked, which is convenient for the staff to quickly confirm the position and replenish the mortar later;

[0044] After all actions are completed, the alarm 32 sounds again to remind the staff to continue moving the scraping plate 11 to perform the scraping operation.

[0045] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
