Description

Technical Field

[0001] The present invention belongs to the technical field of engineering construction auxiliary equipment, and particularly relates to a wall plastering leveling device and a using method thereof. Background Art

[0002] In the process of engineering construction, especially in building construction, usually a plumb bob or a theodolite is used to guide the vertical line of the lower layer to the upper layer. By using this method, the flatness of the wall plastering is measured. After the overall plastering leveling is completed, the wall is measured again to ensure the quality. The above method needs to be measured twice before and after, which is time-consuming and there are errors in the two operations, resulting in inaccurate testing.

[0003] Secondly, the existing plastering leveling process often relies on manual experience. When constructing, experienced workers are selected to use a large square ruler for leveling. However, the leveling method often cannot effectively ensure the overall quality of the plastering, and there is also a risk of wall cracking in the later stage due to different thicknesses of the plastering positions. Summary of the Invention

[0010] The first side wall is provided with slag discharge holes, and the second side wall is provided with wire hanging holes;

[0011] When in use, the first limiting part and the second limiting part are arranged in parallel up and down on the wall surface, and at the same time, the first side wall of the limiting ruler in the first limiting part is arranged in the opposite direction to the first side wall of the limiting ruler in the second limiting part.

[0012] Further, the slag discharge holes are circular, used to discharge the extruded plastering material, so that the first side wall in the limiting ruler is evenly pressed against the wall surface.

[0013] Furthermore, the wire hanging holes are of a "concave" structure, and the measuring wires are wound around the upper and lower groups of the wire hanging holes, so that the flatness of the wall is measured using the distance between the measuring wires and the wall.

[0014] Furthermore, the spacing between the slag discharge holes is 5-20 cm, and the diameter of the slag discharge holes is 2-5 cm.

[0015] Furthermore, the slag discharge holes are evenly arranged on the first side wall.

[0016] Furthermore, the spacing between the wire hanging holes is 10-20 cm.

[0017] Furthermore, the wire hanging holes are evenly arranged on the second side wall.

[0018] Furthermore, positioning holes are provided at both ends of the first side wall of the limit ruler.

[0019] Furthermore, the connecting component includes a positioning screw and a positioning nut. The positioning screw passes through the positioning hole, and the other end is locked with the positioning nut, so as to connect and fix a corresponding set of positioning rulers on the wall.

[0024] S4: passing the measuring rope through the wire hanging holes of the first limiting part and the second limiting part, with one end of the measuring rope being fixedly connected to the wire hanging hole of the first limiting part and the other end being connected to the wire weight;

[0025] S5: Observe the distance between the lower end of the measuring rope and the inner wall of the wire hanging hole of the second limiting portion, so as to determine whether the first limiting portion and the second limiting portion are aligned in the gravity direction;

[0026] S6: tighten or loosen the first limiting portion or the second limiting portion by adjusting the positioning nut so that the first line portion is flush with the second limiting portion in the gravity direction;

[0041] The present invention will be described in detail below with reference to the drawings and specific embodiments.

[0042] This embodiment provides a wall plastering leveling device, as Figure 1-6 shown, which includes a first limiting part arranged at the upper part of the wall and a second limiting part arranged at the lower part of the wall. Both the first limiting part and the second limiting part are assembled by two limiting rulers 10 and four connecting components 20. The limiting ruler 10 includes a first side wall 11 and a second side wall 12 with the same length and the same width. One side of the first side wall 11 and the second side wall 12 is vertically and fixedly connected together to form a structure of a 90° angle steel. The lengths of the first side wall 11 and the second side wall 12 are adapted to the width of the wall.

[0043] The first side wall 10 is parallel to the wall surface and is tightly attached to the wall surface. A slag discharge hole 13 is arranged thereon for discharging excess plaster when tightly pressed against the wall surface. A string hanging hole 15 is arranged on the second side wall 12. The shape of the hole is similar to a "concave" structure. The concave opening is vertically oriented towards the direction of the first side wall 11, and the width of the opening is slightly narrower than the width of the bottom of the opening, which is beneficial to fixing the line so that it is stable in the string hanging hole 15.

[0044] The connecting component 20 includes a positioning screw and a positioning nut. The two limiting rulers 10 are arranged on the two side surfaces of the wall with their first side walls 11 facing each other, and then are connected together by the positioning bolt and the positioning nut. The two limiting rulers 10 are connected and fixed to the wall by using the positioning holes 14 arranged at both ends of the first side wall 11.

[0045] By the above content, a second limiting part is arranged at the lower end of the wall. It should be noted here that, first, the first side walls 11 of the limiting rulers 10 forming the first limiting part and the limiting rulers 10 of the second limiting part are arranged in the same direction; second, the distance between the first limiting part and the second limiting part is not greater than the length of the scraping bar used for later leveling.

[0046] To sum up, as Figure 1 shown, two groups of corresponding limiting rulers 10 and connecting components form the first limiting part at the upper end and the second limiting part at the lower end, forming an overall leveling device assembly.

[0047] When both the first limiting part and the second limiting part are pressed tightly against the wall surface, due to the unevenness of the plastered wall surface, the limiting ruler 10 will be bent during the pressing process, which not only causes damage to the limiting ruler 10, but also makes it impossible to carry out the next leveling work, and the construction quality cannot be guaranteed. To solve this problem, a plurality of slag discharge holes 13 are provided on the first side wall 11 of the limiting ruler, and the aperture of the slag discharge holes 13 is not less than 2 cm, but it cannot be too large. The best aperture range is 2-5 cm. At the same time, the setting spacing of the slag discharge holes is preferably between 5-20 cm, and they are evenly arranged on the first side wall 11. Such a structure can effectively discharge the excess plaster during the pressing process, so as to keep the limiting ruler 10 parallel to the wall reference surface and will not cause damage to the limiting ruler 10.

[0048] Furthermore, to solve the problem of repeatedly measuring the wall flatness, a wire hanging hole 15 is provided on the second side wall 12 of the limiting ruler 10. A measuring rope is hung through the wire hanging hole 15 to directly measure the wall flatness, eliminating the process of finding a reference again and arranging relevant instruments, and realizing the dual use of the leveling device assembly.

[0049] Sometimes, the wall not only needs to measure the flatness in the vertical direction, but also the flatness in the horizontal direction. To solve this problem, a plurality of wire hanging holes 15 are provided on the second side wall 12 of the limiting ruler 10. The spacing of the wire hanging holes 15 is preferably set within the range of 10-20 mm, and they are evenly arranged on the second side wall 12. The corresponding spacing can also be adjusted according to the measurement accuracy requirements. In this way, the distance between each line and the wall is measured, and the difference between different distances is used to judge the quality of the wall horizontal flatness.

[0050] In the actual construction process, a method for using a wall plastering leveling impurity is as follows:

[0051] S1: First, before construction, it is necessary to lay out the lines for the wall to be leveled and set the reference line.

[0052] S2; Then, a set of limiting rulers 10 are placed on both sides of the upper end of the wall and are connected and fixed to both sides of the wall through positioning screws and positioning nuts to form the first limiting part.

[0053] S3: Repeat the above steps to set the second limiting part on the wall. The distance between the first limiting part and the second limiting part is set according to the length of the scraping bar, and it should be noted that the distance should be less than the length of the scraping bar.

[0054] S4: After that, pass the measuring rope through the wire hanging holes 15 of the first limiting part and the second limiting part. One end is fixedly connected to the wire hanging hole 15 of the first limiting part, and the other end is connected to a plumb bob.

[0055] S5: Observe the distance between the lower end of the measuring rope and the inner wall of the wire-hanging hole 15 of the second limiting part, so as to judge whether the first wire part and the second limiting part are flush in the gravity direction.

[0056] S6: By adjusting the positioning nut, clamp or loosen the first limiting part or the second limiting part to make the first wire part and the second limiting part flush in the gravity direction.

[0057] S7: After the above steps are completed, the wall can be leveled. Place the two ends of the screed bar on the first side walls 11 of the first limiting part and the second limiting part respectively, and then push the screed bar to level the wall plastering.

[0058] S8: After leveling, pass the measuring rope through the wire-hanging holes 15 of the first limiting part and the second limiting part, fix one end to the wire-hanging hole 15 of the first limiting part, and fix the other end to the wire-hanging hole 15 of the second limiting part.

[0059] S9: Observe the distance between the measuring rope and the wall surface, calculate the flatness of the wall surface, and further judge whether it meets the requirements of the leveling construction quality according to relevant standards.

[0060] The above has described the embodiments of the present invention in detail. The above content is only the preferred embodiments of the present invention and cannot be considered as limiting the scope of implementation of the present invention. All equivalent changes and improvements made according to the scope of the application of the present invention shall still fall within the scope covered by the patent of the present invention.
