Description

A two-way plastering screed auxiliary device Technical Field

[0001] This invention relates to the field of building construction technology, specifically to a two-way plastering and screeding aid. Background Technology

[0002] In traditional wall plastering, plastering spots or screeds are typically used to control the thickness, flatness, and verticality of the plaster. The specific procedure is as follows: First, a standard plastering spot is made at each corner of the wall and a line is drawn between them. Additional plastering spots are made at window sills and corners of walls. Then, a standard plastering spot is made at the bottom corner of the wall using a plumb line. Next, a screed is made approximately every 1-2 meters (using a plumb line to create a mortar strip between the upper and lower plastering spots), with the same height as the plastering spot. This process is called screeding. Finally, plaster is applied between the screeds to level the surface to the height of the screed. Plastering spots control the precision of individual points, while screeds control the precision of a line. The screeding process involves controlling the precision of a line through several points, and then controlling the precision of the entire surface through several lines.

[0003] However, the current common method of screeding involves manually applying an interface agent to the side of a ruler and then applying mortar or plaster. After adjusting the thickness of the screed using a level, the workers remove the ruler by tapping it when the mortar or plaster is semi-dry, thus separating the ruler from the screed. When making vertical screeds, the amount of mortar or plaster on the side of the ruler will definitely be greater than the amount required for the screed. Furthermore, the bottom of the horizontal screed is unsupported, which causes mortar or plaster to fall during the screeding process, affecting the screeding effect and wasting a certain amount of mortar. Summary of the Invention

[0004] The purpose of this invention is to overcome the shortcomings of the prior art and provide a two-way plastering screeding aid, which is equipped with a vertical screeding component and a horizontal screeding component, so that the horizontal and vertical screeding operations of the wall can be completed in one go when making screeds, effectively reducing the difficulty of horizontal screeding and greatly improving the efficiency of screeding.

[0005] To achieve the above objectives, the present invention provides a bidirectional plastering screeding aid. It is characterized by comprising a vertical screeding assembly and a horizontal screeding assembly. The vertical screeding assembly includes a vertical mounting plate, an air pump, a base plate, an adjusting plate, an air bladder, and a limiting rod.

The limiting rod is located at the upper part of the vertical mounting plate and is fixedly connected to it. The base plate and the limiting rod are located on the same side of the vertical mounting plate, and the distance from the top of the base plate on the side away from the vertical mounting plate to the vertical mounting plate is equal to the distance from the top of the limiting rod on the side away from the vertical mounting plate to the vertical mounting plate. The air bladder is located between the vertical mounting plate and the adjusting plate and is used to move the adjusting plate in a direction away from or towards the vertical mounting plate. The air pump is connected to the air bladder.

The connecting seat is located in the middle of the horizontal rib-forming assembly, the horizontal plate is located on the left and right sides of the connecting seat, the limiting plate is arranged parallel to the horizontal plate, the adjusting screw is threaded to the horizontal plate, and one end of the adjusting screw passes through the horizontal plate and is rotatably connected to the limiting plate.

[0007] The horizontal screed assembly is connected to the vertical screed assembly via a connecting seat.

[0008] Furthermore, the bidirectional plastering screed auxiliary device is characterized in that: the vertical screed assembly further includes a first guide ruler, a second guide ruler, a first connecting plate, and a second connecting plate. The first guide ruler and the first connecting plate are arranged along the length direction of the vertical plate and are disposed on the first edge of the vertical plate. The first guide ruler is hinged to the vertical plate. The first connecting plate is connected to the vertical plate and is arranged perpendicular to the vertical plate. The second guide ruler and the second connecting plate are also arranged along the length direction of the vertical plate and are disposed on the edge of the vertical plate opposite to the first edge. The second guide ruler is hinged to the vertical plate. The second connecting plate is connected to the vertical plate and is arranged perpendicular to the vertical plate. The edge connecting the base plate and the vertical plate is adjacent to the first edge.

[0009] The first straightedge is spaced apart from the first connecting plate, and the second straightedge is also spaced apart from the second connecting plate. The spacing between the first straightedge and the first connecting plate and the second straightedge and the second connecting plate are used to install the horizontal rib assembly.

[0010] Furthermore, the bidirectional plastering screeding aid is characterized in that: both the first connecting plate and the second connecting plate are made of transparent material.

[0011] Furthermore, the bidirectional plastering screed aid is characterized in that: both the first connecting plate and the second connecting plate are provided with scale markings, and the scale markings are provided along the first connecting plate and the second connecting plate from the end away from the vertical plate to the end closer to the vertical plate.

[0012] Furthermore, the bidirectional plastering screeding aid is characterized in that: both the first connecting plate and the second connecting plate can be detachably installed on the vertical mounting plate.

[0013] Furthermore, the bidirectional plastering and screeding aid is characterized in that: the number of airbags is multiple, the multiple airbags are arranged sequentially along the length direction of the vertical plastering plate, and the multiple airbags are connected in series and connected to an air pump.

[0014] Furthermore, the bidirectional plastering and screeding aid is characterized in that: the connecting seat includes a connecting piece, a first fixing plate, a second fixing plate, and a rotating connecting member; one end of the connecting piece is connected to one end of the first fixing plate, and the connecting piece is perpendicular to the first fixing plate; the other end of the connecting piece is connected to one end of the second fixing plate, and the connecting piece is perpendicular to the second fixing plate.

[0015] The horizontal plate includes a left horizontal plate and a right horizontal plate. The other end of the first fixed plate is fixedly connected to one end of the left horizontal plate, and the other end of the second fixed plate is fixedly connected to one end of the right horizontal plate. The rotating connector is at least partially connected to the first fixed plate and at least partially connected to the second fixed plate. An arc-shaped groove is provided in the middle of the vertical plate. The rotating connector cooperates with the arc-shaped groove and can rotate within the arc-shaped groove after being inserted into it.

[0016] Furthermore, the bidirectional plastering screeding aid is characterized in that: elastic elements are provided on the ends of the first connecting plate and the second connecting plate near the horizontal screeding assembly;

[0017] The horizontal screed assembly is also provided with a slot that cooperates with the first guide ruler and the second guide ruler. When the horizontal screed assembly is rotated to a horizontal position, the first guide ruler and the second guide ruler are engaged in the slot.

[0018] This invention provides a bidirectional plastering screeding aid with the following advantages: By setting up a vertical screeding component and a horizontal screeding component, with the horizontal screeding component being housed inside the vertical screeding component, the screeding aid is more convenient to carry and move. Simultaneously, by inflating several sets of airbags with an air pump, the airbags can push the adjusting plate more smoothly. Furthermore, radially graduated markings are provided on the outside of the rotating connecting plate, allowing observation of the distance from the adjusting plate to the wall, thereby determining the screed thickness. The limiting groove on the horizontal screeding component further enhances the screeding effect. The vertical screed assembly collects excess mortar from within. The position of the limiting plate within the limiting groove is adjusted by rotating the adjusting screw, ensuring the distance from the limiting plate to the wall matches the required screed thickness. Mortar is then filled into the gap between the limiting plate and the wall, ensuring the total amount of mortar used in screed fabrication is approximately equal to the required amount. This results in more precise mortar usage. Furthermore, the vertical and horizontal screed assemblies are set perpendicularly, allowing for simultaneous horizontal and vertical screed fabrication of the wall, effectively reducing the difficulty of horizontal screed fabrication and significantly improving efficiency.

[0037] Embodiments of the invention will now be described in more detail with reference to the accompanying drawings. While some embodiments of the invention are shown in the drawings, it should be understood that the invention can be implemented in various forms and should not be construed as limited to the embodiments set forth herein. Rather, these embodiments are provided to provide a more thorough and complete understanding of the invention. It should be understood that the accompanying drawings and embodiments are for illustrative purposes only and are not intended to limit the scope of protection of the invention.

[0038] As shown in Figures 1, 2, 3, 4, 5, and 6, this embodiment discloses a bidirectional plastering screeding aid, which includes a vertical screeding component 100 and a horizontal screeding component 200; wherein, the horizontal screeding component 200 is connected to the vertical screeding component 100 via a connecting seat 204; the vertical screeding component 100 includes a vertical mounting plate 101, an air pump 103, a base plate 104, an adjusting plate 105, an airbag 106, and a limiting rod 107, the vertical... An adjustment groove 108 is provided on the vertical plate 101. The adjustment plate 105 is arranged parallel to the vertical plate 101 and located within the adjustment groove 108. The bottom plate 104 is located at the lower part of the vertical plate 101 and is arranged along the lower edge of the vertical plate 101. The limiting rod 107 is located at the upper part of the vertical plate 101 and is fixedly connected to the vertical plate 101. The bottom plate 104 and the limiting rod 107 are located on the same side of the vertical plate 101, and the bottom plate... The distance from the side of 104 away from the vertical plate 101 to the vertical plate 101 is equal to the distance from the side of the limiting rod 107 away from the vertical plate 101 to the vertical plate 101. The airbag 106 is disposed between the vertical plate 101 and the adjusting plate 105 and is used to drive the adjusting plate 105 to move away from or towards the vertical plate 101. The air pump 103 is connected to the airbag 106. A horizontal rib-scraping assembly 200 is also included, comprising water... The assembly includes a flat plate 201, a limiting plate 202, an adjusting screw 203, and a connecting seat 204. The connecting seat 204 is located in the middle of the horizontal rib assembly 200. The horizontal plate 201 is located on the left and right sides of the connecting seat 204. The limiting plate 202 is arranged parallel to the horizontal plate 201. The adjusting screw 203 is threadedly connected to the horizontal plate 201, and one end of the adjusting screw 203 passes through the horizontal plate 201 and is rotatably connected to the limiting plate 202.

[0039] In this embodiment, by setting up a vertical screed assembly 100 and a horizontal screed assembly 200, the horizontal and vertical screeding operations of the wall can be completed in one go during screed fabrication, effectively reducing the difficulty of horizontal screeding and greatly improving screeding efficiency. Meanwhile,

[0040] By inflating the airbag 106 with the air pump 103, the airbag 106 can push the adjusting plate 105. The adjusting plate 105 squeezes out the excess mortar between itself and the wall, so that the thickness of the screed reaches the required height. The excess mortar flows into the space between the horizontal screed assembly 200 and the wall for horizontal screeding. This ensures that the total amount of mortar used when making the screed is basically equal to the amount of mortar required for the screed, making the mortar usage more precise.

[0041] As shown in Figure 3, the vertical rib assembly 100 further includes a first guide ruler 109, a second guide ruler 110, a first connecting plate 111, and a second connecting plate 112. The first guide ruler 109 and the first connecting plate 111 are arranged along the length direction of the vertical plate 101 and are disposed on the first edge of the vertical plate 101. The first guide ruler 109 is hinged to the vertical plate 101. The first connecting plate 111 is connected to the vertical plate 101 and is arranged perpendicular to the vertical plate 101. The second guide ruler 110 and the second connecting plate 112 are also arranged along the length direction of the vertical plate 101 and are disposed on the vertical plate 101. On the edge opposite to the first edge on plate 101, the second straightedge 110 is hinged to the vertical plate 101, and the second connecting plate 112 is connected to the vertical plate 101 and is perpendicular to the vertical plate 101. The edge where the base plate 104 and the vertical plate 101 are connected is adjacent to the first edge. The first straightedge 109 is spaced apart from the first connecting plate 111, and the second straightedge 110 is also spaced apart from the second connecting plate 112. The spacing between the first straightedge 109 and the first connecting plate 111 and the spacing between the second straightedge 110 and the second connecting plate 112 are used to install the horizontal rib assembly 200.

[0042] In this embodiment, the first guide ruler 109 and the second guide ruler 110 are hinged to the vertical plate 101. When the plastering screeding aid is not in use, the first guide ruler 109 and the second guide ruler 110 are turned outwards and the horizontal screeding assembly 200 is rotated to a vertical position. At this time, the horizontal screeding assembly 200 can be stored inside the vertical screeding assembly 100, making the screeding aid easier to carry and move. The first guide ruler 109 and the second guide ruler 110 can be hinged to the vertical plate 101 using hinges.

[0043] In this embodiment, both the first connecting plate 111 and the second connecting plate 112 are made of transparent material.

[0044] The first connecting plate 111 and the second connecting plate 112 are both provided with scale markings 114, which are arranged along the first connecting plate 111 and the second connecting plate 112 from the end away from the vertical plate 101 to the end closer to the vertical plate 101.

[0045] Both the first connecting plate 111 and the second connecting plate 112 can be detachably mounted on the vertical mounting plate 101.

[0046] The rotating connecting plate is made of transparent material, which makes it easy to observe the position of the adjusting plate 105 and determine the height of the punching rib. At the same time, the rotating connecting plate is equipped with a scale, which can be used to quickly determine and control the height of the punching rib, thereby improving the efficiency of punching the rib.

[0047] In this implementation, the first connecting plate 111 and the second connecting plate 112 can be made of transparent plexiglass. The rotating connecting plate is detachably mounted on the vertical mounting plate 101 using a plug-in method, allowing for easy installation and removal. Specifically, a slot with a width similar to the rotating connecting plate is cut on the side of the vertical mounting plate 101 where the rotating connecting plate is mounted. The rotating connecting plate can then be inserted into the slot, forming a detachable connection. When the rotating connecting plate becomes contaminated or damaged after the plastering process, it can be removed and replaced with a new one, thus extending the service life of the plastering screeding aid.

[0048] In this embodiment, there are multiple airbags 106, which are arranged sequentially along the length of the vertical plate 101. The multiple airbags 106 are connected in series and connected to the air pump 103.

[0049] Multiple airbags 106 are arranged in sequence, which makes it more stable when the airbags 106 push the adjustment groove 108, resulting in higher rib density, higher strength, and better overall rib formation.

[0050] As shown in Figures 5 and 6, the connecting seat 204 includes a connecting piece 205, a first fixing plate 206, a second fixing plate 207, and a rotating connector 208. One end of the connecting piece 205 is connected to one end of the first fixing plate 206, and the connecting piece 205 is perpendicular to the first fixing plate 206. The other end of the connecting piece 205 is connected to one end of the second fixing plate 207, and the connecting piece 205 is perpendicular to the second fixing plate 207.

[0051] The horizontal plate 201 includes a left horizontal plate 209 and a right horizontal plate 210. The other end of the first fixing plate 206 is fixedly connected to one end of the left horizontal plate 209, and the other end of the second fixing plate 207 is fixedly connected to one end of the right horizontal plate 210. The rotating connector 208 is at least partially connected to the first fixing plate 206 and at least partially connected to the second fixing plate 207. The vertical plate 101 has an arc-shaped groove 113 in the middle. The rotating connector 208 cooperates with the arc-shaped groove 113, and the rotating connector 208 can rotate within the arc-shaped groove 113 after being inserted into it.

[0052] In this embodiment, the vertical screed assembly 100 and the horizontal screed assembly 200 are rotatably connected, and the horizontal screed assembly can be housed inside the vertical screed assembly. There are two sets of limiting rods 107, which are symmetrically fixedly connected to the top two sides of one side of the vertical plate 101. The bottom plate 104 is fixedly connected to the bottom of the vertical plate 101 on the side away from the air pump 103. An adjustment groove 108 is provided on the front end face of the vertical plate 101. An adjustment plate 105 is slidably connected inside the adjustment groove 108. An airbag 106 is provided on the adjustment plate 105 and the vertical plate 101. The airbag 106 is connected to the adjustment plate 105 and the vertical plate 101 by bonding. An arc-shaped groove 113 for installing the horizontal screed assembly 200 is provided on the inner part of the middle of the vertical plate 101.

[0053] The horizontal mortar screed assembly 200 includes two sets of horizontal plates and two sets of fixing plates. The two sets of horizontal plates are a left horizontal plate 209 and a right horizontal plate 210, and the two sets of fixing plates are a first fixing plate 206 and a second fixing plate 207. Each set of horizontal plates has a fixing plate fixedly connected to one adjacent end. The two sets of fixing plates are fixedly connected to each other via a connecting piece 205. Each set of fixing plates has a connecting seat 204 fixedly connected to its front end. A limiting groove is formed on each horizontal plate, and a limiting plate 202 is slidably connected inside the limiting groove. An adjusting screw 203 is rotatably connected to the front end of each horizontal plate, with one end of the adjusting screw 203 passing through the horizontal plate and rotatably connected to the limiting plate. A set of guide plates for draining excess mortar is fixedly connected to the side of the limiting rod 107 away from the mortar.

[0054] In this embodiment, elastic elements 102 are provided on one end of the first connecting plate 111 and the second connecting plate 112 near the horizontal punching assembly 200.

[0055] The horizontal rib-straightening assembly 200 is also provided with a slot that cooperates with the first straightedge 109 and the second straightedge 110. When the horizontal rib-straightening assembly 200 is rotated to a horizontal position, the first straightedge 109 and the second straightedge 110 are engaged in the slot.

[0056] In this embodiment, by rotating the horizontal screed assembly 200, the vertical screed assembly 100 and the horizontal screed assembly 200 can form a cross shape, allowing the device to simultaneously screed the wall in both vertical and horizontal directions. During screeding, excess mortar squeezed out can be guided to the interior of the horizontal screed assembly 200 through the guide plate, preventing mortar from flowing along the wall and effectively avoiding excessive mortar application during screeding, thus preventing mortar waste.

[0057] One set of limiting rods, adjacent to the base plate 104, is vertically arranged with a first guide ruler 109 and a first connecting plate 111. The other set of limiting rods, adjacent to the base plate 104, is vertically arranged with a second connecting plate 112 and a second guide ruler 110. Specifically, after the horizontal rib assembly 200 is housed inside the vertical rib assembly 100, both sides of the horizontal rib assembly 200 are blocked by the first guide ruler 109 and the first connecting plate 111. The first guide ruler 109 is rotatably connected to the front end face of the vertical plate 101 via a hinge, and the first connecting plate 111 is fixedly connected to the front end face of the vertical plate 101. The first connecting plate 111 is made of transparent plastic, and radial markings are provided on its outer surface. A set of guides is set on each side of the vertical screed assembly 100, with one set of guides on top and the other set on the bottom, so that the horizontal screed assembly 200 can only rotate in the direction of the vertical screed assembly 100 where the guides are set. The distance from the adjustment plate 105 to the wall can be observed through the scale markings on the outside of the first connecting plate 111, and the thickness of the screed can be determined.

[0058] A gap is provided between the first straightedge 109 and the first connecting plate 111, and an elastic element 102 is fixedly connected to the side adjacent to the first straightedge 109 and the first connecting plate 111.

[0059] Specifically, by compressing the elastic element 102, the horizontal punching assembly 200, after rotating to be perpendicular to the vertical punching assembly 100, can further rotate a distance equal to the compression of the elastic element 102 in the direction of the elastic element 102. At this time, when the straightedge is rotated to be perpendicular to the vertical plate 101, the horizontal punching assembly 200 rotates under the push of the elastic element 102, causing the straightedge to engage in the corresponding slot on the horizontal punching assembly 200. The elastic element 102 can be an elastic pad made of rubber.

[0060] The air pump 103 is connected to the airbag 106 via an air tube. The airbag 106 is cylindrical and has several sets of airbags connected in series radially. When the air pump 103 inflates the airbag 106, the volume of the airbag 106 increases. When the airbag 106 increases in size, it moves the adjusting plate 105 between the adjusting groove 108 and the two sets of limiting rods 107.

[0061] During the screeding process, mortar is added between the two sets of limiting rods 107. The mortar falls above the base plate 104. The volume of the airbags 106 is adjusted by the air pump 103, which in turn changes the position of the adjusting plate 105. The adjusting plate 105 compresses the mortar. When the mortar height is higher than the limiting rods 107, the mortar overflows through the limiting rods 107 and finally flows into the horizontal screeding assembly 200. When the air pump 103 inflates the airbags 106, the air pressure in the airbags 106 is equal due to the air pressure, resulting in a more stable push of the adjusting plate 105 by the airbags 106.

[0062] The size and position of the rotating connector 208 are adapted to the arc groove 113, and the horizontal punching rib assembly 200 is rotatably connected to the vertical punching rib assembly 100 through the rotating connector 208. It should be noted that the assembly of the rotating connector 208 and the arc groove 113 must be tight, and the friction after assembly must be large enough so that the horizontal punching rib assembly 200 will not fall out of the vertical punching rib assembly 100 when the side of the vertical punching rib assembly 100 with the limiting rod 107 is facing down.

[0063] A slot is provided on the upper end of the horizontal plate 201 and the connecting piece 205 on one side. The width of the slot is equal to the thickness of the straightedge. The slot is used to hold the straightedge. A slot is also provided on the lower end of the horizontal plate 201 and the connecting piece 205 on the other side.

[0064] Specifically, when the horizontal screed assembly 200 is perpendicular to the vertical screed assembly 100, the straightedges on both sides of the front end face of the vertical screed assembly 100 will be inserted into the slots on the two sets of horizontal plates 201, so that the position of the straightedges is fixed and will not rotate outward of the vertical screed assembly 100 during the screeding operation.

[0065] It should be noted that the thickness of the connecting piece 205 is thin enough, that is, the thickness of the connecting piece 205 is less than the required thickness of the rib, and the maximum thickness of the connecting piece 205 is no more than 15mm.

[0066] The working principle of the bidirectional plastering screeding auxiliary device in this embodiment is as follows: During screeding operations, the vertical screeding component 100 and the horizontal screeding component 200, after being unfolded, are supported by a support frame and attached to the wall where screeding operations are required. Mortar is transported through a mortar delivery pipe to the space between the two sets of limiting rods 107. At this time, the mortar is supported by the base plate 104 and will be placed between the adjusting plate 105 and the wall. Then, air is blown into the airbag 106 by the air pump 103, so that the distance between the adjusting plate 105 and the wall is reduced evenly. The distance is further reduced by the engraving on the outside of the first connecting plate 111. The distance between the adjusting plate 105 and the wall is observed to be the required screed thickness. Excess mortar added earlier will be squeezed by the adjusting plate 105 and fall into the horizontal screed assembly 200. Refer to the scale markings and rotate the adjusting screw 203 to adjust the position of the limiting plate 202 from the wall so that the distance between the limiting plate 202 and the wall is the required screed thickness. Then fill the gap between the limiting plate 202 and the wall with mortar. After the mortar dries, remove the screed auxiliary device along the vertical direction of the wall to complete the horizontal and vertical screeding operations of the wall.

[0067] This invention provides a bidirectional plastering screeding aid, which, by setting up a vertical screeding component 100 and a horizontal screeding component 200, with the horizontal screeding component 200 retractable inside the vertical screeding component 100, makes the screeding aid more convenient to carry and move. Simultaneously, by inflating several sets of airbags 106 with an air pump 103, the airbags 106 can push the adjusting plate 105 more smoothly. Furthermore, radially graduated markings are provided on the outside of the connecting plate, allowing observation of the distance from the adjusting plate 105 to the wall, thereby determining the screed thickness. A limiting groove on the horizontal screeding component 200 collects excess mortar from inside the vertical screeding component 100. The limiting groove is formed on the horizontal plate 201, and the limiting plate 202 is installed in the limiting groove. Then, the position of the limiting plate 202 inside the limiting groove is adjusted by rotating the adjusting screw 203 so that the distance from the limiting plate 202 to the wall is equal to the required thickness of the screed. Then, mortar is filled into the gap between the limiting plate 202 and the wall so that the total amount of mortar used when making the screed is basically equal to the amount of mortar required for the screed. The amount of mortar used is more precise. Furthermore, the vertical screed component 100 and the horizontal screed component 200 are set vertically, so that the horizontal and vertical screeding operations of the wall can be completed in one go when making the screed. This effectively reduces the difficulty of horizontal screeding and greatly improves the efficiency of screeding.
