Description

Technical Field

[0001] The invention relates to the technical field of building construction, in particular to a concrete slope leveling device and method. Background Art

[0002] At present, it is common to find the slope of structures or buildings during the construction of basement structures in the construction industry. As far as the current situation of the industry is concerned, the conventional methods for slope control in concrete slope construction are: ash cake control method, column rebar one-meter line control method, and manual leveling method. The above three concrete slope control methods have major drawbacks: 1. The ash cake control method requires first measuring with a level and making ash cakes of the designed elevation on the ground at a certain distance. The ash cakes need to be arranged and adjusted one by one, which takes a long time, especially in large-scale construction, and the efficiency is low. At the same time, the ash cakes are easily collided with construction equipment, washed away by rain or damaged by humans, resulting in the failure of the reference point. Moreover, once the concrete is covered during the pouring process, it is often impossible to confirm the height of the concrete. The position of the ash cake is determined, and the construction quality is not high; 2. The one-meter line control method for column dowels. When pouring concrete, the slope-finding workers need to hold a ruler larger than one meter and measure from the one-meter line down to the concrete surface to ensure the slope of the concrete. Because the spacing between the column dowels is too large, the one-meter line cannot cover the entire construction site, so it can only ensure the accuracy of some positions. Most positions are judged by the naked eye and experience, and the accuracy is not high; 3. The manual leveling method requires one person to walk into the construction site with a tower ruler, place the tower ruler on the concrete surface to measure the elevation and calculate whether the current slope of the concrete meets the requirements according to the design drawings. This method requires continuous calculation and back and forth concrete finishing. The accuracy rate is high but the construction efficiency is extremely poor. Summary of the invention

[0027] The present invention is further described below in conjunction with specific embodiments, the purpose of which is only to provide a better understanding of the content of the present invention. Therefore, the examples given do not limit the protection scope of the present invention.

Among them, a battery for powering the vibration motor 2 and the level 6 is also provided on the scraping base plate 1.

[0029] When the scraping device of the present invention is used for construction, the tower ruler 10 is first placed on the front side of the concrete slope leveling and scraping device to ensure that the tower ruler 10 is placed vertically relative to the horizontal ground; then the worker needs to observe the scale D1 indicated by the laser beam 8 emitted by the level 6 on the tower ruler 10, hold the handle 7 and press down the scraping plate 1 to adjust the inclination angle of the scraping plate 1, wherein the inclination angle of the scraping plate 1 can be adjusted according to the horizontal distance between the front end of the scraping plate 1 and the tower ruler 10, the horizontal distance between the laser emission point of the level 6 and the tower ruler 10, and the scale D2 indicated by the laser beam 8 emitted by the level 6 on the tower ruler 10 after the scraping plate 1 is pressed down. After adjusting to the preset inclination angle, hold the handle 7 and drag the scraping device. While the scraping plate 1 scrapes the concrete for slope leveling, the vibration generated by the vibration motor 2 can also make the concrete more dense. The device can monitor and adjust the inclination angle of the scraping plate 1 in real time through the laser beam 8 emitted by the level 6 in cooperation with the tower ruler 10, ensuring the precise control of the concrete slope; avoiding the problems of human error and insufficient precision in the traditional ash cake control method, and is suitable for projects with high precision requirements. In addition, the vibration motor 2 installed on the scraping plate 1 can vibrate the concrete during the scraping process to improve the compactness of the concrete; reducing the subsequent separate vibration steps, and improving the overall quality of the concrete.

[0030] The support rod 3 is tilted, and the support rod 3 tilts from bottom to top toward the side away from the scraping bottom plate 1, and the angle between the support rod 3 and the scraping bottom plate 1 is greater than or equal to 75°; the support rod 3 is tilted (angle ≥75°) to ensure the stability of the device and the convenience of operation.

[0031] A baffle plate 9 is provided on one side of the scraping plate 1 near the handle 7, and the baffle plate 9 is arranged tilted upward; in this embodiment, the baffle plate 9 has an inclination angle greater than or equal to 45°. The baffle plate 9 is provided to prevent concrete from overflowing onto the scraping plate 1 when workers drag the device, and the concrete sinks as it is dragged, thereby improving the practicability of the device and the convenience of construction.

[0032] Two support frames 11 are arranged on the side of the scraping plate 1 away from the handle 7. The two support frames 11 are respectively located at the two ends of the scraping plate 1. A curing film winding cylinder is detachably connected between the two support frames 11, and a curing film 12 is wound on the curing film winding cylinder. An insertion rod 13 is slidably inserted on the support frame 11, and the insertion rod 13 is provided with an external thread. A locking nut 14 is threadedly connected to the inner and outer sides of the insertion rod 13; a bearing is arranged on one end of the insertion rod 13 located on the inner side of the support frame 11, and the outer diameter of the bearing is adapted to the inner diameter of the curing film winding cylinder, and the two ends of the curing film winding cylinder are inserted on the two bearings.

[0033] When installing the curing film winding tube, first loosen the locking nut 14, adjust the insertion rod 13, insert the curing film winding tube between the two insertion rods 13, and then tighten the locking nut 14. When disassembling, loosen the locking nut 14, adjust the insertion rod 13, remove the curing film winding tube, and then tighten the locking nut 14.

[0034] A counterweight is provided at the bottom of the hemispherical inner seat 502 .

[0035] There are several locking pieces, which are evenly distributed along the hemispherical jacket 501. The locking pieces are locking screws threadedly connected to the hemispherical jacket 501. The A end of the locking screw is located on the outside of the hemispherical jacket 501, and the B end is located on the inside of the hemispherical jacket 501. When the B ends of the several locking screws are all in contact with the outer wall of the hemispherical inner seat 502, the hemispherical inner seat 502 is locked.

[0036] The method for performing concrete slope leveling using a concrete slope leveling device comprises the following steps:

[0037] S1: First, place the ruler 10 in front of the concrete slope leveling device to ensure that the ruler 10 is placed vertically relative to the horizontal ground; at the same time, record the horizontal distance X1 between the front end of the leveling base plate 1 and the ruler 10, and the horizontal distance X2 between the laser emission point of the level 6 and the ruler 10;

[0038] S2: When the scraped bottom plate 1 is in a horizontal state, observe the scale D1 indicated by the laser beam 8 emitted by the level 6 on the tower ruler 10; calculate the slope adjustment movement unit S1;

[0039] S3: Holding the handle 7, the scraping plate 1 is driven to rotate through the inclined rod 4 and the support rod 3. The level 6 is always in a horizontal state. By observing the scale D2 indicated by the laser beam 8 emitted by the level 6 on the tower ruler 10, the inclination angle of the scraping plate 1 is adjusted in combination with the slope adjustment moving unit S1;

[0040] S4: After adjusting to the preset tilt angle, the position of the level 6 is locked by a locking member;

[0041] S5: At intervals, an elevation control line is set on the reference object around the construction site with D2 as the elevation, and the handle 7 is held to drag the scraping device to perform a slope finding and scraping operation. During the slope finding and scraping operation, it is necessary to make sure that the level bubble in the level 6 is located in the middle position, and at the same time, the laser beam 8 of the level is projected on the elevation control line; while the scraping plate 1 scrapes the concrete for slope finding and flattening, the vibration generated by the vibration motor 2 can also make the concrete more compact;

[0042] S5: After the first slope leveling and scraping operation is completed, the curing film winding cylinder is installed between the two support frames 11, and the curing film 12 is pulled and placed on the concrete after the first slope leveling and scraping operation, and then the handle 7 is held to drag the scraping device. At this time, the vibration motor 2 is turned off. While the second slope leveling and scraping operation is being performed, the curing film 12 moves with the scraping device and is laid on the concrete. During the second slope leveling and scraping operation, it is necessary to ensure that the level bubble in the level 6 is in the middle position, and at the same time, the laser beam 8 of the level is projected on the elevation control line.

[0043] The method can perform slope finding, leveling and compaction during the first slope finding and leveling operation, and can perform slope finding, leveling and compaction during the second slope finding and leveling operation. The maintenance film 12 can be laid while the second leveling is being performed, thereby improving the construction efficiency and the construction quality.

[0044] For example, when the horizontal distance X1 between the front end of the scraping plate 1 and the tower ruler 10 is 500mm, and the horizontal distance X2 between the laser emission point of the level 6 and the tower ruler 10 is 2000mm, when the level 6 is in a horizontal state, the scale D1 indicated by the laser beam 8 emitted by the level 6 on the tower ruler 10 is 1000mm; the slope adjustment movement unit S1 is calculated to be 20mm, that is, the scale indicated by the laser beam 8 on the tower ruler 10 moves up and down by 20mm, which is 1% of the slope; taking the required slope of 5% as an example, the handle 7 is held by the inclined rod 4. And the support rod 3 is pressed down to scrape the bottom plate 1. After the bottom plate 1 is pressed down and scraped, when the laser beam 8 emitted by the level 6 hits the scale D2 indicated on the tower ruler 10 to be 900mm, the slope is adjusted to 5%; at regular intervals, an elevation control line is set with an elevation of 900mm on the reference objects around the construction site; the concrete slope scraping device is placed on the poured concrete, and the first slope scraping operation and the second slope scraping operation are performed. During the operation, it is necessary to make sure that the horizontal bubble in the level 6 is in the middle position. At the same time, the laser beam 8 of the level is projected on the elevation control line.

[0045] The above description is only the preferred embodiment of the present invention, and does not limit the scope of rights of the present invention. All equivalent changes made by using the contents of the present invention specification and its drawings are included in the scope of rights of the present invention.
