[0033] The utility model provides a kind of drawing measuring scale 10 suitable for stair construction, as shown in Figure 1 It includes: first cantilever 100, second cantilever 200, positioning assembly 300 and base 400, first cantilever 100 and second cantilever 200 are located on base 400.
[0034] As shown in Figure 2 Base 400 is provided with basic reference edge 401;First cantilever 100 is provided with first length reference edge 101, and first length reference edge 101 is perpendicular to basic reference edge 401;Second cantilever 200 is provided with second length reference edge 201, and second length reference edge 201 is perpendicular to basic reference edge 401, and the distance between second length reference edge 201 and first length reference edge 101 is adjustable.
[0035] The number of positioning assembly 300 is two, one of which is slidably arranged on first cantilever 100, and the other is slidably arranged on second cantilever 200, and the distance between positioning assembly 300 and basic reference edge 401 is adjustable.
[0036] In this embodiment, first cantilever 100 and second cantilever 200 are slidably arranged on base 400. Preferably, as shown in Figure 3 The end of first cantilever 100 and second cantilever 200 is provided with limiting piece 500, and limiting piece 500 is slidably arranged on base 400. And, base 400 is provided with limiting slot 410 parallel to basic reference edge 401, limiting piece 500 is provided with convex edge 510 matched with limiting slot 410, and limiting piece 500 is provided with locking bolt 520, and adjusting locking bolt 520 makes limiting piece 500 slide or fix on base 400.
[0037] It should be noted that the number and cross-sectional shape of limiting slot 410 and convex edge 510 can be adjusted adaptively according to actual needs. For example, in this embodiment, base 400 is provided with limiting slot 410 on side surface and upper surface, and the cross-section of limiting slot 410 on upper surface is L-shaped structure (as shown in Figure 3As shown in the figure, the cross section of the convex rib 510 corresponding to the L-shaped structure is also L-shaped structure. In this way, under the cooperation of the limiting groove 410 and the convex rib 510, the limiting piece 500 can smoothly slide on the base 400, thereby avoiding disengagement of the two.
[0038] In the embodiment, as shown in the figure, Figure 3 and Figure 4 As shown in the figure, the limiting piece 500 is provided with an extension plug 530, and the end of the first cantilever 100 and the second cantilever 200 is provided with a plug slot 110, which is adapted to the extension plug 530, so as to realize the connection of the limiting piece 500 with the first cantilever 100 or the connection of the limiting piece 500 with the second cantilever 200. In addition, the plug can be further fixed by a screw, so that the limiting piece 500 and the first cantilever 100 (or the second cantilever 200) are not easy to disengage and shake after being connected.
[0039] As shown in the figure, Figure 5 The positioning assembly 300 comprises a sleeve body 310, an adjusting screw 320 and a top holding piece 330. The sleeve body 310 is sleeved on the first cantilever 100 or the second cantilever 200. The adjusting screw 320 is provided on the sleeve body 310 through threaded connection, and the end of the adjusting screw 320 abuts against the first cantilever 100 or the second cantilever 200. The top holding piece 330 is provided on the sleeve body 310, and the end of the top holding piece 330 forms an abutting vertex 331. In work, the abutting vertex 331 is used for abutting against the edge of the ceramic tile to be cut, so as to realize the positioning of the drawing measuring ruler 10 on the ceramic tile, thereby facilitating the drawing of the area to be cut (the specific principle is described below).
[0040] Preferably, the base 400, the first cantilever 100 and the second cantilever 200 are all provided with a scale (not shown in the figure), so as to facilitate the accurate adjustment of the distance between the first cantilever 100 and the second cantilever 200 and the position of the positioning assembly 300 on the first cantilever 100 and the second cantilever 200 by the construction worker.
[0041] Preferably, the base 400 is provided with an inclined surface, and the edge of the inclined surface forms a basic reference edge 401. In this way, the design of the inclined surface makes the wall thickness at the basic reference edge 401 thinner, which is not easy to block the line of sight of the construction worker during drawing, thereby facilitating the construction worker to draw by using the drawing measuring ruler 10 suitable for the stair construction.
[0042] The working principle of the drawing measuring ruler 10 of the utility model will be described below in combination with the above structure:
[0043] It should be pointed out in advance that in the prior art, before the staircase is built, the designer determines the length, the number and the size of the steps according to the user's requirements, and then the construction personnel perform the construction. However, due to the lack of reference in the construction process, the built staircase steps are prone to obvious errors, which leads to the need for further finishing of the staircase, reducing the work efficiency; at the same time, it is not conducive to the subsequent skirting line laying. Through the drawing measuring ruler 10 of the utility model, the construction personnel can conveniently obtain a piece of wood board or skirting tile for construction reference, thereby providing real-time reference for the building staircase, reducing the construction error.
[0044] Specifically, first, the designer determines the number and size of the steps, for example, the number of steps is 11, and the width of each step is 28 cm and the height is 16 cm, and the height of the skirting line is 10 cm.
[0045] Then, during the construction, the construction personnel take out the drawing measuring ruler 10, slide to adjust the first cantilever 100 and the second cantilever 200, so that the distance L between the first length reference edge 101 and the second length reference edge 201 is 28 cm, that is, the width of the step; and adjust the position of the positioning assembly 300 on the first cantilever 100 and the second cantilever 200, wherein the positioning assembly 300 of the first cantilever 100 is adjusted to the scale mark 16 cm (that is, the height of the step), and the positioning assembly 300 of the second cantilever 200 is adjusted to the scale mark 26 cm (that is, the height of the step plus the height of the skirting line).
[0046] Then, the construction personnel stick the drawing measuring ruler 10 against the flat tile 20 (or wood board), so that the abutting vertices 331 of the two positioning assemblies 300 abut against the straight edges of the tile. At this time, the drawing measuring ruler 10 surrounds a trapezoidal area on the surface of the tile, as shown in Figure 6 The construction personnel draw the area on the surface of the tile with a pen. Then, the drawing measuring ruler 10 is translated, and the first length reference edge 101 is moved to the originally second length reference edge 201, at this time, the drawing measuring ruler 10 surrounds a same trapezoidal area again, and the construction personnel draw again, so that two same and adhered trapezoidal areas are obtained (as shown in Figure 7 With the same method, 11 trapezoidal areas (that is, corresponding to the number of steps) are drawn. Then, the trapezoidal areas are cut out as a whole (as shown in Figure 8 The skirting tile used for construction reference can be obtained. Finally, the tile (or wood board) is laid on the wall, and the construction personnel can refer to it to perform the construction, thereby reducing the construction error of each step.
[0047] In practice, part of the stairs is added with skirting line on the side close to the wall after the completion of the construction, in this case, due to the obvious error between the multi-step, the prior art adopts the combined way to realize the paving, that is, cutting the ceramic tile into multiple triangular plates and multiple rectangular plates, and then combining them with each other, so as to make up the error. However, this combined way has the following disadvantages: first, it will cause the stair skirting line to have many link seams, and the aesthetic property is poor; second, the staff needs to cut the ceramic tile frequently, which will cause more loss and low work efficiency.
[0048] In this case, the drawing measuring ruler 10 of the utility model can draw the accurate shape of the multi-step on the complete ceramic tile, so as to cut out the complete skirting line ceramic tile. The specific operation is as follows: first, the construction worker measures and records the size of each step, during which the construction worker can use other measuring tools to measure, or can use the first cantilever 100 or the second cantilever 200 to measure; then, the construction worker adjusts the drawing measuring ruler 10 according to the measured data and the steps of the above working principle, and then draws the shape of the multi-step on the flat ceramic tile (as shown in Figure 8 Finally, the drawn area is cut off and paved on the wall. In this way, the skirting line of the multi-step is prepared as a whole, and the problem of the prior art that the aesthetic property is poor and the work efficiency is low is solved.
[0049] In the embodiment, the first cantilever 100 and the second cantilever 200 are fixed relative to the limiting piece 500, and the limiting piece 500 can be detached from the base 400, so as to facilitate the storage of the drawing measuring ruler 10.
[0050] In other embodiments, the limiting piece 500 is arranged on the first cantilever 100 or the second cantilever 200 by rotating around the shaft (not shown in the figure). In this way, the first cantilever 100 and the second cantilever 200 can rotate relative to the limiting piece 500, and when not in use, the limiting piece 500 does not need to be detached, and only needs to be rotated to be close to the base 400, so as to realize the folding storage.
[0051] In addition, there are many ways to adjust the distance between the first length reference edge 101 and the second length reference edge 201. For example, in other embodiments, the first cantilever 100 is fixedly arranged on the base 400, and the second cantilever 200 is slidingly arranged on the base 400, so that the distance between the first length reference edge 101 and the second length reference edge 201 can be changed by adjusting the second cantilever 200 only; for another example, in other embodiments, the base 400 is a telescopic structure that can be adjusted, and the first cantilever 100 and the second cantilever 200 are respectively fixed at the two ends of the base 400, so that the distance between the first length reference edge 101 and the second length reference edge 201 can also be changed by changing the telescopic length of the base 400.
[0052] In summary, the utility model discloses a drawing measuring scale 10 suitable for stair construction to solve the low efficiency of the prior art stair step construction, the unevenness, and the unattractive stair skirting line problem, thereby facilitating the operation of the construction staff, and improving the work efficiency.

It should be pointed out that for ordinary skilled persons in the art, without departing from the concept of the utility model, a number of modifications and improvements can be made, which all belong to the protection scope of the utility model. Therefore, the protection scope of the utility model patent should be subject to the appended claims.
