Description

Technical Field

[0001] This utility model relates to the field of building construction technology, and in particular to a screed pusher used in ground mortar leveling construction. Background Technology

[0002] In the construction and decoration industry, when leveling floors with mortar in small-scale projects and home renovations, to achieve a level and smooth mortar surface, it is necessary to first create several compacted elevation reference lines on the floor at predetermined intervals, using a laser-guided horizontal line as a benchmark. This is commonly known in the industry as "screeding lines," and creating these lines is fundamental to successful floor leveling. Currently, interior floor leveling typically uses non-slurry mortar with plasticity, commonly referred to domestically as semi-dry mortar. Semi-dry mortar is widely used for flooring in interior renovation projects both domestically and internationally. Existing methods involve first laying a layer of semi-dry mortar on the floor, then using an aluminum alloy ruler to press and create several compacted elevation reference lines at predetermined intervals, and finally leveling the entire floor using these reference lines. This method is very difficult to implement and requires a high level of skill and experience from the craftsman, necessitating repeated adjustments and pressing with a ruler to complete the task. Therefore, we have proposed a screeding tool for floor mortar leveling to solve these problems. Utility Model Content

[0003] This application provides a screed pusher for use in ground mortar leveling construction, which solves the problem of screeding in ground leveling construction. It can be used to push and smooth the mortar on the ground in a straight line with the help of a track.

[0004] This application provides a screed pusher for use in ground mortar leveling construction, including a groove assembly, an arm plate installed on the side of the groove assembly, a screw column provided at the lower end of the arm plate, a fulcrum screw rod installed on the side of the groove assembly, and a push plate body rotatably connected to the fulcrum screw rod;

[0005] The main body of the pusher plate consists of a pusher surface, a sloping pressing surface, and a smoothing surface. The upper end of the main body of the pusher plate is provided with a hole sleeve, which is connected to the fulcrum screw. The main body of the pusher plate is provided with a support plate, which has an arc-shaped hole. The screw column on the arm plate passes through the arc-shaped hole on the support plate, and a clamping element is provided on the screw column.

[0006] Preferably, a plurality of rollers are rotatably mounted on the inner wall of the chute assembly.

[0007] Preferably, it also includes a toothed plate installed on the shovel surface of the shovel body.

[0008] Preferably, the toothed plate is fixed to the pusher surface of the pusher plate body by toothed plate screws.

[0009] Preferably, the clamping element on the screw is a screw nut.

[0010] Preferably, the inclined pressing surface and the polishing surface are inclined together.

[0011] As can be seen from the above technical solution, this application provides a screed pusher for mortar leveling construction. In use, on the mortar-laid ground, at the set interval position, using the laser horizontal line as the observation and the local compaction of mortar points as support, a horizontally placed metal pipe is used as a track. The screed pusher is placed on the track. First, the main body of the pusher plate is rotated around the fulcrum screw so that the lower end of the arc-shaped hole stops at the screw column position and the clamping part is locked. At this time, the shovel end of the pusher surface contacts the mortar layer. By holding and pushing the sliding groove assembly, the screed pusher moves on the track to level the mortar layer in a straight line. Then, the main body of the pusher plate is rotated around the fulcrum screw so that the upper end of the arc-shaped hole stops at the screw column position and the clamping part is locked. At this time, the smoothing surface is parallel to the long side of the sliding groove assembly. The screed pusher is pushed on the track, and the mortar layer is smoothed by the inclined pressure surface and the smoothing surface. When the trowel is used to smooth the rough surface of the mortar layer, the horizontal position of the smooth surface is lower than that of the trowel tip, and the inclined pressure surface allows the rough mortar layer to be gradually pressed onto the smooth surface, achieving a linear smoothing and pressure application. In ground mortar leveling, horizontally placed metal pipes, using them as tracks, and employing screeding tools to create screeds in the mortar significantly improves the operability of ground mortar construction, reduces difficulty, and greatly enhances the efficiency and quality of screeding.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] 1. By setting up the chute assembly, arm plate and push plate body, the support surface formed by the track can be used for sliding to horizontally scrape and smooth the cement mortar.

[0014] 2. By adjusting the position of the arc-shaped hole on the screw relative to the screw post, the angle of the smearing plate body can be adjusted around the fulcrum screw, allowing the smearing plate body to switch between the pushing and pressing states.

[0015] In summary, this application utilizes a track installed on a metal pipe to stably slide along the track during ground leveling and screeding, allowing the mortar to be linearly leveled and smoothed. This achieves rapid screeding using the mortar itself, improving construction efficiency and quality. Attached Figure Description

[0022] To enable those skilled in the art to better understand the technical solutions in this application, the technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings.

[0023] See Figure 1-4 A screeding tool for mortar leveling construction is disclosed. This application utilizes a horizontally placed aluminum alloy square tube as a track for screeding. It includes a chute assembly 1, with rollers 2 rotatably mounted on the inner wall of the chute assembly 1. In use, the chute assembly 1 is fastened onto the horizontally placed track 15, and the chute assembly 1 slides on the track 15 through the rollers 2. An arm plate 3 is installed on the side of the chute assembly 1, and the arm plate 3 can be fixed to the chute assembly 1 with screws. A screw post 4 is provided at the lower end of the arm plate 3. A fulcrum screw 5 is also installed on the side of the chute assembly 1, and a pusher plate body is rotatably connected to the fulcrum screw 5. The pusher plate body can rotate along the fulcrum screw 5 and be adjusted to different positions to switch between scraping and smoothing functions of the mortar layer. Specifically, due to the straightness and load-bearing capacity of the track 15, the screeding tool sliding along the track 15 performs linear leveling and smoothing of the mortar layer with the track 15 as a reference.

[0024] Specifically, the main body of the pusher plate consists of a pusher surface 6, a beveled pressing surface 7, and a smoothing surface 8. The upper end of the pusher plate main body has a perforated sleeve 11, which is connected to the fulcrum screw 5. The pusher plate main body rotates around the fulcrum screw 5 through the perforated sleeve 11. The pusher plate main body has a support plate 12 with an arc-shaped hole 13. The screw rod 4 on the arm plate 3 passes through the arc-shaped hole 13 on the support plate 12. The screw rod 4 is equipped with a clamping component, which is a screw nut 14. By tightening or loosening the screw nut 14, the pusher plate main body is fixed and adjusted. When the pusher plate main body rotates, the arc-shaped hole 13 moves on the screw rod 4. When it moves to the adjustment position, the pusher plate main body is fixed by rotating the clamping component, thereby switching the pusher plate main body to perform the functions of pushing flat and smoothing.

[0025] This utility model also includes a toothed plate 9 installed on the push surface 6 of the push plate body. The toothed plate 9 is fixed to the push surface 6 of the push plate body by toothed plate screws 10. Specifically, the toothed plate 9 is provided with elongated mounting holes. When the toothed plate screws 10 are loose, the toothed plate 9 can slide along the push surface 6. After adjustment, it is fixed by the wing screws 10. At the same time, the toothed plate 9 can also be replaced according to the usage requirements. In use, the push plate body is rotated around the fulcrum screw, so that the toothed plate 9 comes into contact with the mortar layer. This can reduce the resistance of movement and also have the function of combing and distributing the mortar, forming a sawtooth mortar rough surface, which is conducive to the uniform distribution of mortar in the later stage and is more conducive to leveling.

[0026] In this invention, the inclined pressing surface 7 and the smoothing surface 8 are inclined together, so that the rough mortar layer can be gradually pressed onto the smoothing surface 8 through the inclined pressing surface 7, which plays a progressive pressing role and reduces the resistance during smoothing, while improving the smoothing quality.

[0027] As can be seen from the above technical solution, when performing mortar leveling on the ground in small-scale projects and home decoration projects, according to the required leveling thickness, semi-dry mortar is first fully laid on the ground. At this time, the surface of the mortar is not horizontal. On the ground with the semi-dry mortar laid, at the set intervals, using the laser horizontal line as an observation point and relying on the compaction of local mortar points, a long aluminum alloy square tube is placed horizontally as a track 15. The screed pusher is placed on the track 15. First, the main body of the pusher plate is rotated around the pivot screw 5 so that the lower end of the arc-shaped hole 13 stops at the position of the screw column 4 and the screw nut 14 is tightened. At this time, the shovel end of the pusher 6 contacts the mortar layer. By holding and pushing the sliding groove assembly 1, the screed pusher moves on the track 15 to level the mortar layer. Then, the main body of the pusher plate is rotated around the pivot screw 5 so that the arc-shaped hole 13 stops at the position of the screw column 4 and the screw nut 14 is tightened. At this time, the shovel end of the pusher 6 contacts the mortar layer. By holding and pushing the sliding groove assembly 1, the screed pusher moves on the track 15 to level the mortar layer. Then, the main body of the pusher plate is rotated around the pivot screw 5 so that the arc-shaped hole 13 stops at the position of the screw column 4 and the screw nut 14 is tightened. 13. The upper end stops at the screw column 4 and the screw nut 14 is tightened. At this time, the smoothing surface 8 is parallel to the long side of the sliding groove assembly 1. The screed pusher is pushed on the track 15. The mortar layer is smoothed by the inclined pressure surface and the smoothing surface 7. When the main body of the pusher plate is pushed to smooth the rough surface of the mortar layer, since the horizontal position of the smoothing surface 8 is lower than the horizontal height difference of the pusher surface 6, and there is an inclined setting of the inclined pressure surface 7, the rough mortar layer can be transferred and pressed onto the smoothing surface 8 through the inclined pressure surface 7. This achieves the effect of straight-line pushing, pressing and smoothing of the mortar. By using this method to make screeds for the ground mortar, several ribs with the same height are made at the set intervals and compacted and smoothed. Then, a ruler is used to support the two ribs and the fully laid mortar is scraped smooth to complete the leveling construction of the entire ground. Using this method significantly improves the operability of ground mortar construction, reduces the difficulty, and improves efficiency and quality.
