Description

Technical Field

[0001] The utility model relates to the field of building construction, in particular to a large-area concrete cushion leveling device. Background Art

[0002] The concrete cushion is the middle layer between the reinforced concrete foundation and the foundation soil. Its function is to make its surface flat to facilitate the tying of steel bars on it. It also plays a role in protecting the foundation. They are all plain concrete and do not require steel bars. If there are steel bars, it cannot be called a cushion and should be regarded as a foundation slab. Usually, it needs to be leveled on the concrete cushion.

[0003] Generally, workers manually apply concrete blocks to mark the ground leveling bars, and then use infrared rays to level the entire ground. After solidification, concrete is poured in different areas, and the areas are initially leveled by using ash cakes, and then the entire ground is leveled again. This practice is affected by the shape of the implementation area, the manual operation errors of on-site installation workers, the solidification shrinkage of concrete blocks, and the protection of finished products on site, which has a great impact on the flatness of the overall concrete cushion layer and the quality of the final finished surface. At the same time, the manual marking of concrete blocks is inefficient and the construction accuracy is poor. The later poured concrete is prone to poor integration with the position of precast concrete blocks, resulting in hollowing and cracking. Utility Model Content

[0018] The following is combined with Figure 1 This application is described in further detail.

[0019] An embodiment of the present application discloses a large-area concrete cushion leveling device, which requires vertical drilling of ash cakes by means of a drilling rod before use; the drilling rod includes three layers which are sequentially sleeved from the inside to the outside, wherein the innermost layer is a drill rod, the middle layer is a threaded barrel, and the outermost layer is a compacting barrel; the drill rod thread is inserted into the threaded barrel and both ends extend out of the threaded barrel, one end of the drill rod is a pointed head, and the other end is provided with a spirit level, i.e., a level bubble; the compacting barrel is sleeved outside the threaded barrel, and a compacting scraper is provided at one end of the compacting barrel close to the pointed head of the drill rod, and an annular handle is connected to the outer wall of the compacting barrel through a plurality of connecting rods.

[0020] When using the drilling rod, place the pointed head on the ash cake. After the horizontal bubble returns to the center, hold the threaded barrel or the top of the drill rod, lift the compacting barrel up and down, so that the compacting barrel impacts the ash cake and compacts it. After the ash cake is compacted, hold the threaded barrel to press the compacting barrel, rotate the drill rod, and make the drill rod move forward under the operation of the thread, so as to complete the vertical drilling on the ash cake, drill the positioning hole, and complete the rib marking.

[0021] In order to facilitate the determination of the depth of the positioning hole, a scale line is provided on the outside of the threaded barrel, and the depth of the positioning hole drilled can be known by observing the scale line.

[0022] The leveling device includes a scraper 2 and two slide rails 1, the two ends of the slide rails 1 are mounted on two ash cakes and the two slide rails 1 are arranged in parallel; positioning screws are provided below the two ends of the slide rails 1, and the positioning screws are inserted into the positioning holes of the ash cakes; the scraper 2 includes a slide rod 3 and a flat plate 4, the two ends of the slide rod 3 are respectively mounted on two adjacent slide rails 1, and two circular rings 41 are connected to the flat plate 4 by welding, and the two circular rings 41 are mounted on the slide rod 3, so that the flat plate 4 can slide along the length direction of the slide rod 3, and a drag rod 42 is also provided on the flat plate 4.

[0023] After the leveling device is assembled and placed, the concrete cushion layer can be scraped flat by dragging the flat plate 4 along the length direction of the slide rail 1 through the drag rod 42.

[0024] In order to prevent the slide rod 3 from falling off the slide rail 1 during sliding, a stop rod 31 is provided at both ends of the slide rod 3; at the same time, in order to enable the slide rail 1 to be erected on ash cakes with different spacings, long holes are opened at both ends of the slide rail 1, and one end of the positioning bolt 12 is threadedly connected with a nut after passing through the strip hole 11; the nut is turned away from the slide rail 1 to allow the positioning screw to slide in the strip hole 11, and when adjusted to the right position, the nut is turned to press against the slide rail 1 to limit the positioning screw.
