Description

An automatic control device for flatness of cast-in-place concrete slabs

technical field

The patent of the invention relates to the field of construction engineering, in particular to an automatic control device for flatness of cast-in-place concrete slabs.

Background technique

Due to the advantages of good structural integrity, durable structure, and quick construction, the cast-in-place concrete structure is widely used in the current field of construction engineering. When pouring concrete, if there is a large deviation in the flatness of the cast-in-place concrete slab after pouring, it will cause unevenness on the floor of the subsequent house, and it will take extra manpower and material resources to level the protrusions or sag. Therefore, when pouring concrete, it is necessary to control and adjust the flatness of the cast-in-place concrete slab.

The traditional method of adjusting the flatness of the cast-in-place concrete slab is manual adjustment. The construction workers use a tape measure to measure the elevation of the concrete slab surface, and then use a scraper to level the concrete slab surface. Because the distance between the concrete slab and the ground is small, the construction personnel need to use a low posture such as squatting to make the line of sight flush with the tape measure when measuring the elevation. There is still a certain error in the elevation of the slab surface, and there will still be a certain height difference between the smoothed concrete slab surface and the ground.

Detailed ways

The technical solution of the present invention will be further described in detail below in conjunction with the accompanying drawings, but the protection scope of the present invention is not limited to the following description.

Referring to FIGS. 1 to 3 , an embodiment of the present invention provides an automatic control device for flatness of a cast-in-place concrete slab.

As shown in Figure 1, an automatic control device for flatness of cast-in-situ concrete slabs includes a base 1 and a bracket 2, the bracket 2 is fixedly mounted on the base 1, and one end of the bracket 2 is connected with a cross bar 3, so that A pressure wheel mechanism is connected to the cross bar 3; the pressure wheel mechanism can reciprocate horizontally along the cross bar 3, and the pressure wheel mechanism can reciprocate vertically.

As shown in Figure 2, the pressure wheel mechanism includes a pressure wheel 8 and a lifting device, and the lifting device includes a gear set 9 and a lifting rod 10; a servo motor for driving the gear set 9 to rotate is fixedly installed on the slider 5 11. The elevating rod 10 is provided with a rack 12 meshing with the gear set 9; the pressure wheel 8 is rotatably connected to the end of the elevating rod 10 through a bearing.

Because in the process of rolling the concrete slab back and forth along the horizontal direction, the pressure roller 8 needs to keep the height of the vertical direction of the pressure roller 8 constant; After moving up and down in the vertical direction, it can ensure that the lifting rod 10 will not slide in the vertical direction when the pressure roller 8 moves in the horizontal direction.

It should be noted that this group of movements is carried out separately from the telescoping movement of the piston rod of the cylinder 7 mentioned below and does not interfere with each other, which avoids the pressure exerted by the pressure roller 8 on various areas of the concrete slab that may be caused by the two groups of movements at the same time Inhomogeneity, resulting in wavy undulations on the concrete slab surface, further ensures the flatness of the concrete slab surface.

As shown in Fig. 3, described cross bar 3 is provided with slide rail 4, is slidably connected with slide block 5 on described slide rail 4, and described pressure wheel mechanism is fixedly connected with slide block 5; Described cross bar 3 quantity is Two, the number of the sliders 5 matches the number of the crossbars 3, the sliders 5 are fixedly connected with the moving rods 6, and one side of the bracket 2 is provided with a cylinder for driving the moving rods 6 to reciprocate in the horizontal direction 7. The end of the piston rod of the cylinder 7 is fixedly connected with the middle part of the moving rod 6 .

The telescopic movement of the piston rod of the cylinder 7 drives the moving rod 6 to reciprocate in the horizontal direction, and drives the pressure wheel mechanism to reciprocate in the horizontal direction through the slider 5, so that the contact surface with the concrete slab surface has dropped to the specified elevation The pressure wheel 8 can carry out rolling work on the concrete slab surface, and during the rolling process, the concrete higher than the elevation will be squeezed out from the gap between the supports 2, so as to ensure that the elevation of the concrete slab surface after rolling meets the predetermined Require.

The bracket 2 is provided with an infrared sensing device 13 for detecting the contact surface between the pressure roller 8 and the cast-in-situ concrete; 15 is installed on the protrusion 14.

After the required elevation is determined, the infrared sensing device 13 is fastened to the protrusion 14 corresponding to the scale line with the double ear screw 15, which can ensure that the elevation of the contact surface of the pressure wheel 8 and the concrete slab surface is always consistent when it descends , when the construction personnel transfer the present invention to another place with pouring concrete, there is no need to recalibrate the elevation as in the traditional way, and the work efficiency of concrete pouring work is improved.

The support 2 is provided with a control mechanism 16, the signal input end of the control mechanism 16 is connected with the infrared sensing device 13, and the signal output end of the control mechanism 16 is respectively connected with the cylinder 7 and the servo motor 11.

The pinch wheel 8 is an iron pinch wheel 8 or a steel pinch wheel 8; using chrome-plated iron or a steel alloy through quenching and grinding as the material of the pinch wheel 8 can make the surface of the pinch wheel 8 wear-resistant and smooth. While the surface of the board is smooth, the damage to the surface of the pressure roller 8 caused by scratching of the material in the concrete to the pressure roller 8 is reduced, thereby ensuring the service life of the present invention.

The working principle of the present invention is: after placing the present invention at the place to be poured, first fasten the infrared sensing device 13 on the corresponding scale line of the protrusion 14 according to the required elevation, and then pour concrete at the place to be poured until the concrete The board surface slightly exceeds the required elevation distance;

Then the present invention is opened, and the gear set 9 cooperates with the elevating rod 10 to lower the pressure roller 8 until the infrared sensing device 13 detects the pressure roller 8, which means that the pressure roller 8 has reached the height specified by the elevation, and the control mechanism 16 receives the infrared sensor. After the feedback information of the device 13, disconnect the power supply of the servo motor 11 and connect the power supply of the cylinder 7 at the same time, the piston rod of the cylinder 7 pushes the moving rod 6, and the moving rod 6 drives the slider 5 to move horizontally reciprocatingly along the slide rail 4. 5. The fixedly connected pressing wheel mechanism reciprocates along the horizontal direction at the same time, and the pressing wheel 8 can roll the concrete slab surface;

During the rolling process, the excess concrete above the elevation of the concrete slab will be slowly squeezed to both sides by the pressure roller 8. After the rolling work is completed, an instruction will be sent to the control mechanism 16, and the control mechanism 16 will control the lifting The rod 10 rises, the pressure roller 8 gradually lifts away from the concrete slab, and then the construction workers remove the present invention and simply clean up the residual concrete around the concrete slab to complete the finishing work.
