DETAILED DESCRIPTION

[0033] In order to make the personnel in the technical field better understand the technical solutions in the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings.

[0034] Referring to Figures 1-4 A kind of application in ground mortar leveling construction flush muscle support, for supporting track, track is the aluminum alloy pipe material commonly used by bricklayer, specifically, including cross bridge 1, cross bridge 1 two ends are equipped with rear stand leg 2 and front stand leg 3, form installation space in the middle, wherein rear stand leg 2 is equipped with two rear support foot 4, front stand leg 3 is equipped with one telescopic support foot 6 with height adjustable, three points form support surface by.By adjusting the height of rear support foot 4 or telescopic support foot 6, cross bridge 1 can be adjusted to level by observing horizontal display instrument 8, cross bridge 1 is also provided with clamping device, clamping device is located in installation space, for installing track;

[0035] Specifically, clamping device is adjustably provided with main rod 17, main rod 17 passes through cross bridge 1, main rod 17 can be adjusted up and down on cross bridge 1, the lower end of main rod 17 is also provided with track arm support 19, for supporting and installing track 34, and track arm support 19 can also make flush muscle push cutter along track 34 through in flush muscle support.Using, first, through laser level positioning confirmation reference surface, by adjusting the position of main rod 17, so that track 34 and the laser level line projected by laser level are consistent, that is, a horizontal reference surface, i.e.track 34, is obtained, and track 34 is used to flush muscle to preset mortar.

[0036] In this embodiment, during construction, the laser level is placed on the ground, the highest point of the ground undulation error is detected by projecting a laser level line, the thickness of the ground leveling mortar to be laid is determined, and a horizontal line is projected.

[0037] The mixed mortar is ready for use, and the reinforcing bar supports are placed on the ground at appropriate intervals. According to the length factor of the track to be used later, two or more reinforcing bar supports can be placed. The horizontal display instrument 8 on the cross bridge 1 is observed, and the height of the supporting leg is adjusted to make the cross bridge 1 horizontal. The main rod 17 on the clamping device is adjusted, and metal pipes are placed on the supporting arms 19 of the reinforcing bar supports to serve as tracks. The best choice is the aluminum alloy square pipe commonly used by masons to scrape the mortar. Refer to the laser level line projected on the wall of the aluminum alloy pipe as a reference. Adjust the clamping device to move the main rod 17 up and down to align the position with the horizontal line, make the aluminum alloy square pipe horizontal at the set height, place the mortar on one side of the aluminum alloy pipe, gather it into a strip shape and tamp it, so that the upper end surface of the mortar is slightly higher than the height of the horizontal line. Then, the subsequent process can push and smooth the mortar layer by the reinforcing bar pusher.

[0038] Further, in this embodiment, the telescopic supporting leg 6 is provided with a screw thread, and the telescopic supporting leg 6 is sleeved with a screw rod seat 7, which is fixed on the front vertical leg 3. During use, the height of one side of the cross bridge 1 can be adjusted by rotating the telescopic supporting leg 6, and the top end of the telescopic supporting leg 6 is provided with an adjusting knob to improve the convenience of adjusting the telescopic supporting leg 6.

[0039] Further, in this embodiment, the two rear supporting legs 4 are fixed on the rear vertical leg 2 by the supporting leg screws 5. The two rear supporting legs 4 on the rear vertical leg 2 can be folded in a fan shape around the supporting leg screws 5, improving the storage and portability of the reinforcing bar support.

[0040] Furthermore, in this embodiment, the clamping device includes a housing 9, which has a vertical through hole 10, a lever hole 11, and a fulcrum hole 12. The housing 9 also includes a tilting plate 13, which has a tilting plate hole 14, a fulcrum end 15, and a lever 16. The fulcrum end 15 is located within the fulcrum hole 12, serving as a pressure fulcrum for the tilting plate 13. The lever 16 passes through the tilting plate hole 11 and extends to one side of the housing 9. The tilt angle of the tilting plate 13 is adjusted by moving the lever 16. A spring 18 is located within the housing 9. The main rod 17 passes through the vertical through hole 10, the tilting plate hole 14, and the spring 18. The elastic force of the spring 18 causes the adjusted main rod 17 and the tilting plate to... The position of the piece 13 will not change. Specifically, when a downward load is applied to the main rod 17, the shearing force generated by the shearing hole 14 on the inclined shearing piece 13 on the main rod 17 is similar to the semi-circular foot catch principle used by electricians to climb utility poles. The force of the spring 18 keeps the inclined shearing piece 13 in the direction of the shearing force. The greater the force applied to the main rod 17, the greater the shearing force of the inclined shearing piece 13, and the more firmly it is locked onto the main rod 17. When the shearing handle 16 is pinched upward, the shearing force of the inclined shearing piece 13 is instantly lost, and the main rod 17 can move up and down arbitrarily and stay in any position, thereby allowing the track support arm 19 to move up and down arbitrarily and lock in position.

[0041] In this utility model, see Figures 5-7 It also includes a screed pusher for leveling the mortar layer. The screed pusher includes a chute assembly 20, which is equipped with rollers 21. In use, the chute assembly 20 is fastened to the fixed track 34. The chute assembly 20 slides on the track 34 through the rollers 21. An arm plate 22 is installed on the side of the chute assembly 20. The arm plate 22 can be fixed to the chute assembly 20 with screws. A screw post 23 is provided at the lower end of the arm plate 22. A fulcrum screw 24 is also installed on the side of the chute assembly 20. A push plate body is rotatably connected to the fulcrum screw 24. The push plate body can rotate along the fulcrum screw 24. After being adjusted to a suitable position, it is used to scrape and smooth the mortar layer. Specifically, since the horizontal position of the track 34 is accurately positioned, the screed pusher sliding along the track 34 uses the track 34 as a reference to level and smooth the mortar layer.

[0042] The push and trowel plate body is composed of a push trowel surface 25, an inclined pressing surface 26 and a troweling surface 27. The push and trowel plate body has a hole sleeve 30 at the upper end, which is connected to the fulcrum screw 24. The push and trowel plate body rotates around the fulcrum screw 24 through the hole sleeve 30. The push and trowel plate body has a vertical support plate 31, which has an arc-shaped hole 32. The screw column 23 on the arm plate 22 passes through the arc-shaped hole 32 on the vertical support plate 31. A pressing element is arranged on the screw column 23. The pressing element on the screw column 23 is a screw nut 33. The screw nut 33 is used to fix and adjust the push and trowel plate body. When the push and trowel plate body rotates, the arc-shaped hole 32 moves on the screw column 23. When it moves to the adjusted position, the push and trowel plate body is fixed by rotating the pressing element, so as to level and trowel the cement mortar.

[0043] In this embodiment, first, the push and trowel plate body is rotated to contact the push trowel surface 25 with the mortar layer. By holding and pushing the sliding groove assembly 20 to move, the push trowel surface 25 is moved to push the mortar layer to be flat. Then, the inclined pressing surface 26 and the troweling surface 27 of the push and trowel plate body are rotated to contact the leveled mortar layer. The troweling surface 27 is used to trowel the leveled mortar layer. When the push and trowel plate body is pushed to trowel the rough surface of the mortar layer, the horizontal position of the troweling surface 27 is lower than that of the push trowel surface 25. The inclined pressing surface 26 is inclined to transition the rough mortar layer to the troweling surface 27, which reduces the resistance during troweling and improves the troweling quality.

[0044] Specifically, the reinforcing rib pusher is used on the aluminum alloy pipe, the sliding groove assembly 20 is attached to the aluminum alloy pipe, the push and trowel plate body is rotated to the lower end point of the arc-shaped hole 32 with the fulcrum screw 24 as the center, and the push and trowel plate body is locked by the pressing element. The reinforcing rib pusher is pushed on the track 34, and the push trowel surface 25 pushes the mortar layer to form a horizontal mortar rough surface. Then, the push trowel surface 25 is adjusted to the upper end of the arc-shaped hole 32. At this time, the troweling surface 27 of the push and trowel plate body is lower than the lower edge of the push trowel surface 25. The reinforcing rib pusher is pushed on the track 34, and the inclined pressing surface 26 and the troweling surface 27 are used to press and trowel the mortar rough surface to form a smooth surface as the rib reference surface. In general, the length of the aluminum alloy pipe is limited by its portability. The rib needs to be made in multiple segments to form a longer segment. Since the reinforcing rib pusher can pass through the reinforcing rib support along the track 34, the position of the reinforcing rib support can be changed to make a very long rib on the ground. In this way, several ribs can be made at intervals on the ground. After waiting for several hours, the mortar is initially solidified, and the mortar can be filled between the ribs. By relying on the ribs, the ground can be made level.

[0045] Further, in the embodiment, a toothed plate 28 is installed on the push screed body, and the toothed plate 28 is fixed on the push blade surface 25 of the push screed body by toothed plate screws 29. In use, the push screed body is rotated so that the toothed plate 28 is in contact with the mortar layer, which can reduce the moving resistance and can also distribute the mortar, forming a sawtooth-shaped mortar surface, which is beneficial to the uniform distribution of the mortar in the later stage and is more beneficial to leveling.

[0046] From the above technical solution, in use, the mortar can be filled and constructed immediately without waiting for the initial setting of the reinforcing bar mortar. A long thin strip can be selected and laid on the ribbed surface layer that is pressed and smoothed. A long thin strip of high polymer material with excellent flatness and resilience is the best choice. Because the semi-dry mortar has a certain supporting force after compaction, and the material tension of the long thin strip also strengthens the supporting force, the long thin strip can be scraped and filled with mortar, and then the long thin strip is removed and a small amount of material is added. Then, the entire floor can be processed by rubbing or smoothing until the work is completed.
