Description

Technical Field

[0001] The utility model relates to the technical field of construction, and specifically relates to a ground leveling device. Background Art

[0002] When laying floors or thinly pasting rock slabs, it is necessary to precisely level the ground with mortar or concrete. For the mortar leveling in traditional construction, the larger the area, the greater the horizontal error of the manual scraping ruler. There are often horizontal errors of several centimeters. The common leveling methods are to use infrared rays to mark the height or use plaster blocks to mark points for leveling. Not only is the work efficiency low, but it is also extremely susceptible to the influence of the marking setting and the self-shrinkage of the plaster blocks. The flatness of the overall leveling is not ideal. The cost of adding self-leveling cement later is high and it cannot meet the requirements of the party A. Content of the Utility Model

[0003] In view of the problems existing in the prior art, the utility model discloses a ground leveling device, which comprises a galvanized plate, a bearing, positioning holes, fiber screws, screed bars, a positioning rod base, a positioning rod, a movable positioning ruler, and locking screws; four positioning holes are opened on the galvanized plate; the bearing is installed in the center of the upper surface of the galvanized plate; the lower end of the fiber screw is sleeved into the bearing, and the center of the upper end is hollow; one to five mounting screw holes are arranged on the screed bar, and a clamping block and a clamping groove which are matched with each other are respectively arranged at the left and right ends; the positioning rod base is clamped on the screed bar, and a positioning rod is vertically arranged in the center of the upper surface thereof; there are solid lines on the movable positioning ruler, which is installed on the positioning rod and can slide on the positioning rod. A screw hole is opened on the side surface of the movable positioning ruler, and a locking screw is installed in the screw hole.

[0004] As a preferred technical solution of the utility model, the positioning holes are arranged in an array.

[0005] As a preferred technical solution of the utility model, the fiber screw is one of a hollow inner cylindrical shape, an inner triangular shape, an inner hexagonal shape, and an inner octagonal shape; the bearing is one of a cylindrical shape, an inner triangular shape, an inner hexagonal shape, and an inner octagonal shape.

[0006] As a preferred technical solution of the utility model, the positioning rod is provided with scales.

[0007] The beneficial effects of the utility model: The utility model is simple to use. It can be fixed on the cement floor by injecting glue or fixed on the cement floor by nail guns. After connecting the screed bar to the fiber screw, the movable positioning ruler is used to quickly level the screed bar, and the fiber screw exposed on the screed bar is sheared. Then, a leveling ruler is used to scrape the mortar along the upper edge of the screed bar. The overall use is simple and convenient. After the leveling is completed, the screed bar and the fiber screw installed on it can be disassembled, cleaned and reused. Description of the Drawings

[0013] Example 1

[0014] As Figures 1 to 3 shown, the present invention discloses a ground leveling device, including a galvanized sheet 1, a bearing 2, a positioning hole 3, a fiber screw 4, a ribbing strip 5, a positioning rod base 6, a positioning rod 7, a movable positioning ruler 8, and a locking screw 9; four positioning holes 3 are provided on the galvanized sheet 1; the bearing 2 is installed in the center of the upper surface of the galvanized sheet 1; the lower end of the fiber screw 4 is sleeved into the bearing 2, and the center of its upper end is hollow; one to five mounting screw holes are provided on the ribbing strip 5, and a clamping block and a clamping groove that cooperate with each other are respectively provided at the left and right ends; the positioning rod base 6 is clamped on the ribbing strip 5, and a positioning rod 7 is vertically provided in the center of its upper surface; there are solid lines on the movable positioning ruler 8, which is installed on the positioning rod 7 and can slide on the positioning rod 7, and a screw hole is provided on its side, and a locking screw 9 is installed in the screw hole. The positioning holes 3 are arranged in an array, and nails can be directly driven and fixed on the cement floor, and glue can be injected and fixed on the mortar floor. The lower end of the fiber screw 4 is sleeved into the bearing 2 and can rotate. The center of the upper end is hexagonal, triangular, octagonal, etc., and an electric pistol drill or manual rotation can be used to adjust the height of the ribbing strip 5. The movable positioning ruler 8 can slide on the positioning rod 7 and is locked and fixed by rotating the locking screw 9.

[0015] Working principle of the utility model: When the utility model is in use, first place several galvanized sheets 1 at appropriate positions on the ground, then select the screeding strip 5 and install it on the fiber screw 4. Then adjust one of the screeding strips 5 to the preset height, and use the moving positioning ruler 8 to move to the adjustment point to adjust the other screeding strips 5 to the same height. The multiple screeding strips 5 can be connected together by the clamping block and slot at the ends, or they can be not connected to each other. After the adjustment is completed, glue can be injected and fixed through the positioning holes 3. Use the water nozzle scissors to cut the fiber screw 4 flush with the screeding strip 5. Finally, pour the mortar to the same height as the screeding strip 5, and use the straightedge to scrape the mortar flat along the screeding strip 5. Finally, the screeding strip 5 can be removed and hand-polished.
