Abstract
Description
Technical Field
[0001] The present invention relates to the technical field of building construction, and in particular to a ribbing tool assembly and a construction method for ground mortar leveling construction. Background Art
[0002] In the building decoration industry, when performing mortar leveling construction on the ground, in order to make the mortar surface layer horizontal and flat, it is necessary to first use mortar to stack and form strip-shaped raised ribs on the ground based on the laser level line. In the industry, it is commonly known as ribbing. Doing a good job in ribbing is the foundation for doing a good job in ground leveling. Since non-paste mortar with plasticity is currently used for ground leveling in interior decoration, which is commonly known as semi-dry mortar in China, semi-dry mortar is generally used for floor construction in interior decoration projects at home and abroad. The existing construction method is to lay metal or PVC convex ribbing strips on the ground and bond and fix them to the ground with wet mortar. Usually, after the mortar solidifies the next day, mortar is filled and scraped flat in the spaces between the ribbing strips. This method has many operational drawbacks. Due to various factors such as the easy deformation of the ribbing strips after being squeezed by logistics transportation, it is not easy to accurately position during construction and errors will occur, and the mortar is easy to shift when it is not solidified, and at the same time, the consumable cost is also increased. The purpose of this application is to use a tool assembly to quickly make ribs with the mortar body during mortar construction and be able to perform the construction of filling the ribbing material at one time, which can significantly improve the operability of ground mortar construction, reduce the difficulty, enable young people who have just entered the industry to quickly get started, and can significantly improve the efficiency and quality of ribbing.

[0011] Preferably, it further includes a toothed plate installed on the main push plate body, and the toothed plate is fixed on the push shovel surface of the main push plate body by toothed plate screws.
[0012] Preferably, the pressing member on the screw rod column is a screwing nut.
[0013] This application also discloses a method for the construction of ground mortar leveling, based on the tool for screeding in the construction of ground mortar leveling described in any one of the above, including the following steps: S1. Place the laser level on the ground, detect the highest point of the ground undulation error by projecting the laser horizontal line, determine the thickness to be laid for the ground leveling mortar, and project a horizontal line. S2. Install the screeding bracket and adjust the height of the telescopic feet to make the long side of the cross bridge in a horizontal state. S3. Adjust the adjusting handle on the clamping device, move the main rod up and down. Place the track on the support arm of the screeding bracket. Referring to the laser horizontal line projected on the track, adjust the clamping device to move the main rod up and down, so that the track on the support arm at the lower end of the main rod is at the set height and in a horizontal state.
[0014] S4. Referring to the position and height on one side of the track, place the mixed mortar on the ground to form a ridge-shaped long strip. S5. Place the screeding push knife on the track, fit the chute assembly onto the track, swing the main body of the troweling plate around the fulcrum screw to the lower endpoint of the arc-shaped hole, tighten it by screwing the pressing member, hold the screeding push knife and push it on the track. The screeding push knife pushes the uneven mortar into a horizontal state, and the upper plane is a rough surface. S6. Then adjust the main body of the troweling plate to the upper end of the arc-shaped hole, hold the screeding push knife and push it on the track. The inclined pressing surface and the smoothing surface of the main body of the troweling plate press and smooth on the rough surface of the mortar to form a smooth rib.
[0015] As can be seen from the above technical solutions, the present application provides a screeding tool assembly applied to the construction of ground mortar leveling. During the construction process, place the laser level on the ground, detect the highest point of the ground undulation error through the projected laser horizontal line, determine the thickness to be laid for the ground leveling mortar, and project a horizontal line.
[0016] Mix the mortar and set it aside. Place the screeding brackets on the ground at appropriate intervals. The screeding brackets can be placed in two or multiple numbers according to the length factor of the track to be used later. Visually observe the horizontal display on the cross bridge, and adjust the height of the adjustable feet to make the cross bridge horizontal. Adjust the main rod on the clamping device, place the track on the support arm of the screeding bracket as the track, preferably using an aluminum alloy square pipe commonly used by bricklayers to scrape the mortar. Refer to the laser horizontal line projected on the pipe wall of the aluminum alloy pipe as a reference, adjust the clamping device to move the main rod up and down to align with the horizontal line, make the aluminum alloy pipe horizontal and at the set height. Place the mortar on one side of the aluminum alloy pipe, shape it into a strip and pat it firmly, making the upper end surface of the mortar slightly higher than the height of the horizontal line.
[0017] Place the screeding push knife on the aluminum alloy pipe, fit the chute assembly onto the aluminum alloy pipe, swing the main body of the troweling plate around the fulcrum screw to the lower endpoint of the arc-shaped hole, lock it through the pressing member, hold the screeding push knife and push it on the track. The pushing surface shovels out a horizontal rough surface of the mortar on the mortar surface layer at its lower edge height. At this time, adjust the pushing surface to the upper end of the arc-shaped hole. At this time, the smoothing surface of the main body of the troweling plate is lower than the lower edge position of the pushing surface at the height difference of the horizontal line. Hold the screeding push knife and push it on the track. The inclined pressing surface and the smoothing surface press and smooth on the rough surface of the mortar, and thus a smooth surface is transversely pushed and plastered to serve as the rib reference surface. Usually, due to the portability of the aluminum alloy pipe, the length is limited, and the ribs need to be made in multiple sections and continuously formed into a longer section. Since the screeding push knife can pass through the screeding bracket along the track, the position of the screeding bracket can be changed to continuously make very long ribs on the ground. By this method, several ribs are made at the set intervals on the ground. After waiting for a few hours for the mortar to initially solidify, mortar can be filled between the ribs, and a scraper is relied on the ribs to scrape and press, so as to make a whole horizontal ground.
[0018] In this application, the mortar can be laid immediately without waiting for the initial setting of the mortar. A long strip-shaped thin sheet can be selected and placed on the troweled rib surface layer. It is best to choose a common polymer material thin strip with excellent flatness and resilience. Since the plastic accumulation of the dry-mixed mortar after compaction has a certain supporting force and the material tension of the thin strip strengthens a certain supporting force, the leveling bar can be relied on the strip-shaped thin sheet to scrape the filled mortar flat. Then, the thin sheet is removed and a little material is replenished here. Then, according to the later needs, the entire ground can be roughened or polished until the operation is completed.
[0019] Compared with the prior art, the beneficial effects of the present invention are as follows: 1. Through the setting of the cross bridge, front and rear vertical legs, a stable support platform can be formed for horizontal positioning and support of the track used in construction, and both the height and the inclination angle can be adjusted; 2. Through the setting of the clamping device, the track support arm can be clamped, the track can be installed, and the vertical height can be adjusted to achieve the purpose of adjusting and clamping the track; 3. Through the setting of the track support arm, the track can be supported, and the rib pushing blade can pass through the rib support bracket along the track without obstruction, achieving the purpose of connecting the head and tail of the mortar ribs during large-area construction; 4. Through the setting of the chute assembly, the arm plate and the pushing surface, the cement mortar can be leveled and polished on the support formed by the track; 5. By adjusting the angle of the pushing and spreading plate body on the rib pushing blade, the pushing and spreading plate body can be switched between the pushing state and the troweling state.
[0020] In summary, this application can form several horizontal support bodies by adjustment, place straight pipes, and form a horizontal track on an uneven ground to facilitate pushing and spreading mortar with the help of the track; it can also rely on the track and use a leveling tool to push and spread the uneven mortar to form a horizontal rib, and compact and polish it, so as to make multiple ribs. The mortar can be leveled on the ribs, greatly improving the operability and construction efficiency of the construction. BRIEF DESCRIPTION OF THE DRAWINGS

Detailed implementation manners
[0024] In order 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 in conjunction with the accompanying drawings.
[0025] See Figures 1-7 , a ribbing tool assembly for floor mortar screeding construction, including a ribbing support for supporting the track 34. The track 34 is an aluminum alloy pipe commonly used by bricklayers. Specifically, the ribbing support includes a cross bridge 1. The two ends of the cross bridge 1 are provided with a rear vertical leg 2 and a front vertical leg 3, and an installation space is formed in the middle. Among them, the rear vertical leg 2 is provided with two rear support legs 4, and the front vertical leg 3 is provided with a height-adjustable telescopic support leg 6. A support surface is formed by three points. There is a horizontal display instrument 8 on the cross bridge 1. In this application, the horizontal display instrument 8 can select a bubble level. When adjusting, observe the horizontal display instrument 8, and the cross bridge 1 can be adjusted to be horizontal by adjusting the height of the rear support leg 4 or the telescopic support leg 6. A clamping device is also installed on the cross bridge 1. The clamping device is located in the installation space and is used for installing the track 34; Specifically, a main rod 17 is adjustably arranged on the clamping device. The main rod 17 passes through the cross bridge 1 and can be adjusted up and down on the cross bridge 1. A track support arm 19 is further arranged at the lower end of the main rod 17 for supporting and installing the track 34. Moreover, the track support arm 19 can also enable the screeding push knife to pass through the screeding bracket along the track 34. During use, first, the reference plane is located and confirmed through a laser level. By adjusting the position of the main rod 17, the track 34 is made to coincide with the laser horizontal line projected by the laser level, and a horizontal reference plane, that is, the track 34, can be obtained. The preset mortar is screeded through the track 34.
[0026] In the present invention, threads are provided on the telescopic feet 6. A screw seat 7 is sleeved on the telescopic feet 6 in a threaded manner, and the screw seat 7 is fixed on the front leg 3. During use, the height on one side of the cross bridge 1 can be adjusted by rotating the telescopic feet 6. Moreover, an adjustment knob is arranged at the top end of the telescopic feet 6 to improve the convenience of adjusting the telescopic feet 6.
[0027] In the present invention, the two rear feet 4 are superposed and fixed on the rear leg 2 through the foot screws 5. The two rear feet 4 on the rear leg 2 can be fan-folded with the foot screws 5 as the axis, which improves the storage and portability of the screeding bracket.
[0028] In the present invention, the clamping device includes a housing 9. There are a vertical through hole 10, a lever hole 11, and a fulcrum hole 12 in the housing 9. An inclined lever 13 is further arranged in the housing 9. There are a lever hole 14, a fulcrum end 15, and a lever handle 16 on the inclined lever 13. Among them, the fulcrum end 15 is located in the fulcrum hole 12 to serve as a pressure fulcrum for the inclined lever 13. The lever handle 16 passes through the lever hole 11 and extends to one side of the housing 9. By pulling the lever handle 16, the inclination angle of the inclined lever 13 is adjusted. There is a spring 18 in the housing 9. The main rod 17 passes through the vertical through hole 10, the lever hole 14, and the spring 18. Due to the elastic force of the spring 18, the positions of the adjusted main rod 17 and the inclined lever 13 will not change anymore. Specifically, when a downward negative gravity acts on the main rod 17, since the lever hole 14 on the inclined lever 13 generates a shearing force on the main rod 17, similar to the principle of the semi-circular foot buckle for an electrician to climb a telegraph pole, the force of the spring 18 causes the inclined lever 13 to maintain the direction of the shearing force. The greater the force acting on the main rod 17, the greater the shearing force of the inclined lever 13, and thus the firmer the clamping of the main rod 17. When the lever handle 16 is pinched upward, the shearing force of the inclined lever 13 is instantly lost, and the main rod 17 can move up and down arbitrarily and stay at any position, so that the track support arm 19 can move up and down arbitrarily and be fixed in position.
[0029] An application of the present application to a ribbing tool assembly for floor mortar leveling construction further includes a ribbing push knife for leveling the mortar layer. The ribbing push knife includes a chute assembly 20 provided with rollers 21. During use, the chute assembly 20 is buckled on the fixed track 34, and 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, and the arm plate 22 can be fixed to the chute assembly 20 by screws. A screw column 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 main push and smear plate is rotatably connected to the fulcrum screw 24. The main push and smear plate can rotate along the fulcrum screw 24 and is used to scrape and smooth the mortar layer after being adjusted to a suitable position. Specifically, since the horizontal position of the track 34 is accurately positioned, the ribbing push knife sliding along the track 34 levels and smooths the mortar layer with the track 34 as a reference; Specifically, the main push and smear plate is composed of a push shovel surface 25, an inclined pressure surface 26, and a smoothing surface 27. There is a hole sleeve 30 at the upper end of the main push and smear plate. The hole sleeve 30 is connected to the fulcrum screw 24. The main push and smear plate rotates around the fulcrum screw 24 with the hole sleeve 30 as the origin. There is a vertical support plate 31 on the main push and smear plate, and an arc-shaped hole 32 is provided on the vertical support plate 31. The screw column 23 on the arm plate 22 passes through the arc-shaped hole 32 on the vertical support plate 31. A pressing member is provided on the screw column 23. The pressing member on the screw column 23 is a screwing nut 33. The main push and smear plate is fixed and adjusted by the tightness of the screwing nut 33. When the main push and smear plate rotates, the arc-shaped hole 32 moves on the screw column 23. After moving to the adjustment position, the main push and smear plate is fixed by rotating the pressing member, thereby leveling and smoothing the cement mortar; Specifically, first rotate the main push and smear plate so that the push shovel surface 25 contacts the mortar layer, and drive the push shovel surface 25 to move by holding and pushing the chute assembly 20 to move, so as to level the mortar layer. Then rotate the inclined pressure surface 26 and the smoothing surface 27 of the main push and smear plate to contact the leveled mortar layer, and the smoothing surface 27 is used to level the plane of the leveled mortar layer. When pushing the main push and smear plate to smooth the rough surface of the mortar layer, since the horizontal position of the smoothing surface 27 is lower than the horizontal height difference position of the push shovel surface 25, and there is an inclined setting of the inclined pressure surface 26, the rough surface mortar layer can be transitionally pressed and covered onto the smoothing surface 27 through the inclined pressure surface 26, and the mortar is progressively pressed and covered and smoothed, reducing the resistance during smoothing and improving the smoothing quality at the same time.
[0030] In the present invention, a toothed plate 28 installed on the main push and smear plate is fixed to the push shovel surface 25 of the main push and smear plate by toothed plate screws 29. During use, rotate the main push and smear plate so that the toothed plate 28 contacts the mortar layer, which can not only reduce the resistance of movement, but also has the function of combing and distributing the mortar, forming a serrated mortar rough surface, which is beneficial to the uniform distribution of the later mortar and is more conducive to leveling.
[0031] The present invention also includes a method for ground mortar leveling construction, based on the above-mentioned rib punching device for ground mortar leveling construction, comprising the following steps: S1. Place the laser level on the ground, detect the highest point of the ground undulation error by projecting a laser horizontal line, determine the thickness of the ground leveling mortar to be laid, and project a horizontal line; S2. Install the rib bracket and adjust the height of the telescopic legs to make the long side of the cross bridge horizontal; S3. Adjust the adjustment handle on the clamping device to move the main rod up and down, place the track on the support arm of the rib bracket, refer to the laser horizontal line projected on the track, adjust the clamping device to move the main rod up and down, and make the track on the support arm at the lower end of the main rod at the set height and in a horizontal state.
[0032] S4. Place the mixed mortar on the ground to form a ridge-shaped strip based on the position and height of one side of the track; S5. Place the rib pusher on the track, fit the slide assembly on the track, swing the push plate body to the lower end of the arc hole with the fulcrum screw as the center, screw the clamping piece to tighten, hold the rib pusher and push it on the track, the rib pusher will push the uneven mortar into a horizontal state, and the upper plane will be rough; S6. Then adjust the main body of the push-and-paste board to the upper end of the arc-shaped hole, hold the rib-punching push knife and push it on the track, and press and smooth the inclined pressure surface and the smoothing surface of the main body of the push-and-paste board on the rough surface of the mortar to form smooth ribs.
[0033] It can be seen from the above technical solution that in some embodiments, during construction, a laser level is placed on the ground, the highest point of the ground undulation error is detected by projecting a laser horizontal line, the thickness of the ground leveling mortar to be laid is determined, and a horizontal line is projected.
[0034] Mix the mortar for use, place the rib brackets on the ground at appropriate intervals. Two or more rib brackets can be placed according to the length of the track to be used later. Visually observe the level indicator 8 on the cross bridge 1, and adjust the height of the front support 6 to make the cross bridge 1 horizontal. Adjust the main rod 17 on the clamping device to move up and down, place the track 34 on the bracket 19 of the rib bracket as a track, and use the aluminum alloy square tube commonly used by bricklayers to scrape the mortar as the best. Refer to the laser horizontal line projected on the tube wall of the aluminum alloy pipe as a reference, adjust the clamping device to move the main rod 17 up and down to align with the horizontal line, so that the aluminum alloy pipe is in a horizontal state and at the set height, and place the mortar on one side of the aluminum alloy pipe, gather it into a strip shape and pat it down, so that the upper end surface of the mortar is slightly higher than the established ground level to be implemented.
[0035] Place the screeding push knife on the aluminum alloy pipe 34, fit the chute assembly 20 onto the aluminum alloy pipe, pivot the main body of the troweling plate around the fulcrum screw 24 to the lower endpoint of the arc-shaped hole 32, and lock it with the pressing member. Hold the screeding push knife and push it on the track 34. The pushing and scraping surface 25 will scrape out a horizontal mortar rough surface on the mortar surface layer at the height of its lower edge. At this time, adjust the pushing and scraping surface 25 to the upper end of the arc-shaped hole 32 and lock it. At this time, the troweling surface is parallel to the long side of the chute assembly 20. At this time, the troweling surface 27 of the main body of the troweling plate is lower than the position of the lower edge of the pushing and scraping surface in terms of the height difference on the horizontal line. Hold the screeding push knife and push it on the track 34. The inclined pressing surface 26 and the troweling surface 27 will press and trowel on the mortar rough surface. In this way, push and press horizontally to create a smooth surface as the rib reference surface. Usually, due to the limited length of the aluminum alloy pipe for portability, the ribs need to be made in multiple sections and connected into a longer section. Since the screeding push knife can pass through the screeding support along the track, the position of the screeding support can be changed to continuously make very long ribs on the ground. In this way, several ribs are made at the intervals set on the ground. After waiting for a few hours for the mortar to initially solidify, mortar can be filled between the ribs. Rely on the ribs with a scraping bar to scrape and press, so as to create an overall horizontal ground.
[0036] In this application, mortar can be filled and constructed immediately without waiting for the mortar to initially set. A long strip-shaped thin sheet can be selected and laid on the troweled and pressed rib surface layer. It is best to choose a common polymer material thin strip with excellent flatness and resilience. Since the dry-mixed mortar has a certain supporting force after being compacted and the material tension of the thin strip strengthens a certain supporting force, a scraping bar can rely on the strip-shaped thin sheet to scrape and level the filled mortar. Then remove the thin sheet and make a little supplementary material here. Then, according to the later needs, the entire ground can be roughened or troweled until the operation is completed.
[0037] In some embodiments, the screeding push knife can also be used alone for screeding and leveling. When performing mortar leveling construction on the ground in small-area projects and home improvement projects, according to the thickness of the ground that needs to be leveled, first spread semi-dry mortar evenly on the ground. At this time, the surface of the spread mortar is in a non-horizontal state. On the ground where the semi-dry mortar has been spread, at the set spacing positions, with the laser horizontal line as the observation reference and relying on the local compaction of the mortar at some points, horizontally place a long aluminum alloy square tube as the track 34. Place the screeding push knife on the track 34. First, rotate the push and smear plate body around the fulcrum screw 24 so that the lower end of the arc-shaped hole 32 stops at the position of the screw column 23 and tighten the screw nut 33. At this time, the shovel end of the pushing surface contacts the mortar layer. By holding and pushing the chute assembly to move the screeding push knife on the track 34, the mortar layer is leveled. Then, rotate the push and smear plate body around the fulcrum screw 24 so that the upper end of the arc-shaped hole 32 stops at the position of the screw column 23 and tighten the screw nut. At this time, the polishing surface 27 is parallel to the long side of the chute assembly 20. Push the screeding push knife on the track, and level the leveled mortar surface through the inclined pressure surface 26 and the polishing surface 27. When pushing the push and smear plate body to level the rough surface of the mortar layer, since the horizontal position of the polishing surface is lower than the horizontal height difference position of the shovel end of the pushing surface, and due to the inclined setting of the inclined pressure surface, the rough surface mortar layer can be transitionally pressed and covered onto the polishing surface through the inclined pressure surface 26, achieving the effect of linearly pushing, pressing, and covering and polishing the mortar. Using this method to screed the mortar, several ribs with the same height that are compacted and polished are made at the set spacing. Then, rely on a ruler on two ribs and scrape the evenly spread mortar to complete the entire ground leveling construction. Using this method significantly improves the operability of ground mortar construction, reduces the difficulty, and improves the efficiency and quality.
