Description

Technical Field

[0001] The invention relates to a wall plastering construction reference structure and a construction method, belonging to the technical field of building construction. Background Art

[0002] In the existing wall plastering process, plasterers usually use common tools such as spirit levels or rulers to arrange wall plaster cakes. The spirit level is easily affected by indoor and outdoor light, resulting in excessive deviation between the plaster cake and its wall line and other plaster cake control points, and the distance between the plaster cakes cannot be accurately controlled. The plaster cakes are not arranged in a straight line, and the plumb bob method cannot ensure the vertical verticality of the plaster cake surface. This also causes the subsequent ribs that use the plaster cakes as a reference to be unable to remain flat, resulting in the entire wall surface being unable to be controlled in terms of flatness and verticality during the plastering process. Workers are also prone to scratching the surface of the ribs due to uneven ribs when plastering, which further increases the deviation in wall flatness and fails to meet acceptance requirements. Summary of the invention

[0003] In order to solve the above problems existing in the prior art, the present invention provides a wall plastering construction reference structure and a construction method.

[0004] The technical solution of the present invention is as follows:

[0005] A wall plastering construction reference structure comprises a plurality of plaster cakes attached to the wall surface and steel bars connected between two adjacent plaster cakes, wherein the plaster cakes are distributed in a rectangular lattice on the wall surface, the steel bars are connected between two laterally or longitudinally adjacent plaster cakes, and the front side surfaces of each plaster cake are flush with the front side surfaces of the steel bars to form a plaster surface leveling reference grid with a flat surface and perpendicular to the ground.

[0006] Among them, the upper, lower, left and right four side walls of the ash cake are all provided with positioning grooves, and the ends of the steel bars are embedded in the positioning grooves.

[0007] The ash cake is formed by pressing mud through a wall-attachable mold.

[0008] Wherein, the steel bar is a square structure, and the positioning groove fits and matches the end of the square steel bar on three sides.

[0009] Among them, it also includes a length compensation steel bar, and the length compensation steel bar is a retractable structure in the length direction.

[0010] Among them, the length compensation steel bar includes a first steel bar segment and a second steel bar segment, and the connecting ends of the first steel bar segment and the second steel bar segment are respectively provided with a tongue and groove, the front side surfaces of the tongue and groove and the tongue and groove are flush, and the two side walls of the tongue and groove are respectively provided with protrusions, and the two side walls of the tongue and groove are respectively provided with sliding grooves, and the protrusions are embedded in the sliding grooves and can slide along the length direction of the length compensation steel bar.

[0011] A construction method for a wall plastering construction reference structure comprises the following construction steps:

[0012] The first step is to wash and moisten the wall before arranging the ash cakes, and make the ash cakes after the conditions are met;

[0013] The second step is to fill the mortar cake mold with mortar, determine the first ash cake positioning point based on the wall plaster thickness line, illuminate the line emitted by the laser on the mold to overlap the wall control line, and make the level bubble on the mold located in the center, completing the first ash cake control point arrangement;

[0014] The third step is to control the distance between the ash cakes. The subsequent control points are controlled by laser projection between the molds and level bubbles to control the flatness and verticality of the ash cake grid until the wall grid is formed. When the ash cake is about to be formed and stabilized, remove the mold;

[0015] The fourth step is to select steel bars that are suitable for the length of the ash cake spacing to be controlled as ribs. The front side of each ash cake is flush with the front side of the steel bar. The steel bar is embedded in the positioning groove of the ash cake, that is, the surface is flat and perpendicular to the ash surface leveling reference grid on the ground. Only horizontal or vertical steel bars can be used according to actual needs. After correctness, start hanging the mesh and plastering;

[0016] Step 5: When applying the last layer of plaster, apply the mortar slightly thicker than the rib steel bar. Finally, use a scraping tool to roll and scrape off the excess mortar using the front surface of the steel bar as the reference for the thickness of the wall plaster.

[0017] Step 6. After the plaster is semi-dry and solidified, take out the reinforcement steel bars and use mud to repair the reinforcement seams.

[0018] The present invention has the following beneficial effects:

[0019] 1. The ash cake of the present invention is formed by pressing mud through a wall-attachable mold. The level bubble and laser installed on the ash cake mold can realize the rapid arrangement of the ash cakes, ensure the verticality and horizontality between the ash cakes, and establish a more scientific ash cake control grid. Compared with the manual ash cake, the mold ash cake surface is smoother, and there is no problem of uneven plastering surface angles and bumps caused by manual plastering shovels, thereby improving the qualified rate of ash cakes.

[0020] 2. The present invention adopts steel bars to replace traditional ribs, which are connected to the ash cakes through embedded grooves. The ash cake mold with grooves around can be used in conjunction with steel bars as ribs, eliminating the rib punching step. After it is almost formed, it can be removed and reused, effectively improving construction efficiency and quality.

[0021] 3. The surface of the steel strip of the present invention is hard, smooth and has no bumps. It is not easy to be scratched during plastering, and the flatness of the wall plastering can be controlled to a greater extent. In particular, a length compensation steel strip is arranged on the side of the wall to realize length adjustment so that the plaster surface leveling reference grid can completely cover the wall surface. At the same time, the tongue and groove mortise and tenon connection structure is adopted, so that the length compensation steel strip can ensure that the surface is flat without height difference when the length adjustment is satisfied, thereby ensuring that the surface of the entire plaster surface leveling reference grid is flush and perpendicular to the ground.

[0029] The present invention will be described in detail below with reference to the accompanying drawings and specific embodiments.

[0030] See also Figure 1A wall plastering construction reference structure comprises a plurality of plaster cakes 1 attached to the wall surface and steel bars 2 connected between two connected plaster cakes 1, the plaster cakes 1 are distributed in a rectangular lattice on the wall surface, the steel bars 2 are connected between two laterally or longitudinally adjacent plaster cakes 1, and the front side surfaces of each plaster cake 1 are flush with the front side surfaces of the steel bars 2 to form a plaster surface leveling reference grid with a flat surface and perpendicular to the ground. During construction, the grid of each plaster surface leveling reference grid is not hung with a mesh for plastering, and the plastering surface is controlled to be flush with the front side surfaces of the surrounding steel bars 2, so that the entire wall plaster surface is controlled to be flush and perpendicular to the ground, thereby achieving leveling and vertical control;

[0031] See also Figure 2 The upper, lower, left and right side walls of the ash cake 1 are all provided with positioning grooves 11, and the ends of the steel bars 2 are embedded in the positioning grooves 11. The depth of each positioning groove 11 is consistent to ensure that the connecting surface heights of the steel bars 2 and the positioning grooves 11 are consistent. The steel bars 2 are of a square structure, and the positioning grooves 11 fit and match the ends of the square steel bars 2 on three sides.

[0032] See also Figure 4-5 The ash cake 1 is formed by pressing mud through a wall-attachable mold. A level bubble 41 is provided on the upper side of the ash cake mold 4, and laser emitters 42 are provided on the other four sides, namely, the lower, left and right sides. The level bubble 41 is used to ensure that the ash cake mold 4 is aligned. The laser emitters 42 on the other four sides can emit laser rays and compare them with reference objects in the horizontal or vertical direction to ensure that the coordinates of the current ash cake pressing position are accurate.

[0033] See also Figure 3 Since the length and width of the construction wall are uncertain, it is not certain that an integer number of steel bars 2 can be set, so the structure also includes a length compensation steel bar 3, which is a retractable structure in the length direction, by adjusting the length of the length compensation steel bar 3;

[0034] Specifically, the length compensation steel bar 3 includes a first steel bar segment 31 and a second steel bar segment 32. The connecting ends of the first steel bar segment 31 and the second steel bar segment 32 are respectively provided with a tongue and groove 33 and a tongue and groove 34. The front sides of the tongue and groove 33 and the tongue and groove 34 are flush, and the two side walls of the tongue and groove 33 are respectively provided with protrusions 35. The two side walls of the tongue and groove 34 are respectively penetrated by a slide groove 36. The protrusion 35 is embedded in the slide groove 36 and can slide along the length direction of the length compensation steel bar 3 to change the length of the length compensation steel bar 3. Any length adjustment can be achieved within the adjustment stroke range. The tongue and groove mortise and tenon connection structure is adopted, so that the length compensation steel bar 3 can ensure a flat surface without height difference when the length adjustment is satisfied, thereby ensuring that the entire gray surface leveling reference grid surface is flush and perpendicular to the ground.

[0035] Based on the above-mentioned wall plaster surface leveling structure, the present invention also provides a construction method of a wall plastering construction reference structure, comprising the following construction steps:

[0036] The first step is to wash and moisten the wall before arranging the ash cakes, and make the ash cakes after the conditions are met;

[0038] The third step is to control the distance between the ash cakes. The control points thereafter are projected by the laser 3 between the molds and the level bubble 4 to control the flatness and verticality of the ash cake grid until the wall grid is formed. When the ash cake is about to be formed and is stable, remove the mold;

[0039] The fourth step is to select steel bars 2 that are suitable for the length of the ash cake spacing to be controlled as the ribs. The front side of each ash cake 1 is flush with the front side of the steel bars 2. The steel bars 2 are embedded in the positioning grooves 11 of the ash cake 1. That is, the surface is flat and perpendicular to the ash surface leveling reference grid on the ground. Only horizontal or vertical steel bars can be used according to actual needs. After correctness, start hanging the mesh and plastering;

[0040] Step 5: When applying the last layer of plaster, apply the mortar slightly thicker than the reinforcing steel bar 2, and finally use a scraping tool to roll and scrape off the excess mortar using the front surface of the steel bar 2 as the reference for the thickness of the wall plaster;

[0041] Step 6. After the plaster is semi-dry and solidified, take out the reinforcement steel strip 2 and repair the reinforcement seam with mud.
