Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of decorative construction of industrial and civil building projects, and particularly provides a stone anti-slip strip for the cement mortar plastered staircase step. Background Technique
[0002] At present, there are two common anti-slip measures for the external corners of cement mortar staircase steps: applying anti-slip strips with emery on the spot, or inlaying ribbed steel bars at the external corners of the steps. These two measures have the following disadvantages:
[0003] 1) Applying anti-slip strips with emery on the spot:
[0004] Applying anti-slip strips with emery on the spot is difficult to operate, requires high skills for the operator, and is prone to breakage and falling off during later use.
[0005] 2) Inlaying steel bars at the external corners of the steps:
[0006] The steel bars inlaid at the external corners of the steps become smooth on the surface after being rubbed by people walking for a long time and are prone to slipping.
[0007] 3) In view of the actual situation, it is particularly necessary to develop a technical measure with less investment, which can improve the anti-slip performance of the steps and enhance the aesthetics. Summary of the Invention
[0008] The purpose of the utility model is to invent a stone anti-slip strip for the cement mortar plastered staircase step, which solves the problems that the anti-slip strips with emery applied on the spot are prone to breakage and falling off during later use, and the steel bars inlaid at the external corners of the steps become smooth and slippery. It realizes less investment and improves the anti-slip performance and aesthetics of the cement mortar plastered staircase step.
[0009] The utility model is made of white granite, in the shape of a cuboid, with the specification of 50mm×20mm×Lmm (the length L should be adjusted according to the actual project, generally 900mm to 1200mm). The exposed surface of the anti-slip strip is flame-textured to form a rough surface with unevenness of 1 - 2mm, and the chamfer R of the exposed external corner is 5 - 10mm.
[0010] The manufacturing steps of the stone anti-slip strip are as follows:
[0011] First, process the stone strip according to the geometric dimensions required for the stone anti-slip strip 1, then chamfer one of the corners as Figure 1 shown to form a rounded corner, and finally use an oxyacetylene flame to flame-texture the exposed surface of the anti-slip strip to form a rough surface with unevenness of 1 - 2mm.
[0012] Before construction, customize the stone anti-slip strip 1 according to the attached drawings of this patent, and then do the conventional on-site preparation work, such as cleaning the structural surface of the reinforced concrete staircase 3, watering and moistening, measuring and setting out lines, mixing cement mortar, etc.
[0013] When constructing the staircase from bottom to top, first construct the platform and then construct the steps upward. When constructing the steps, first plaster the vertical surface, then press the stone anti-slip strip 1 on top, adjust the position to align the external corner with the line, then trim the vertical surface to make the corner guard fit tightly with the mortar on the vertical surface, and then use the stone corner guard as the horizontal reference for plastering the horizontal surface of the steps.
[0014] After the initial setting of the cement mortar plastering 2, carry out the first troweling, and the second troweling before the final setting. During the operation, the movements should be gentle to avoid disturbing the stone corner guard and causing hollowing.
[0015] Quality standard: After the anti-slip strip is inlaid, installed and corrected, the allowable deviation is 2 mm.
[0016] Advantages or positive effects
[0017] For this technology, the installation elevation and horizontal position deviation of the anti-slip strip are ±5 mm. After actual implementation, the measured results can meet the above technical indicators, and the overall qualified rate reaches 90%.
[0018] The principle of this technology is simple and the operation is convenient. Workers can master it only after a simple technical disclosure.
[0019] The advantages are that the anti-slip strip is simple to manufacture and convenient to construct. Before construction, customize and process the stone anti-slip strip, and inlay it at the external corner when plastering the cement mortar on the staircase steps, which plays a role in improving the anti-slip performance of the staircase steps; it can not only improve the anti-slip performance of the staircase steps, but also prevent the artificial knocking and damage of the staircase steps during use, improving the aesthetics, and the comprehensive effect is remarkable. Description of the drawings
[0020] Figure 1 It is a schematic diagram of the installation of the stone anti-slip strip for the staircase steps.
[0021] In the figure, the stone anti-slip strip 1, the cement mortar plastering 2, and the reinforced concrete staircase 3. Specific implementation method
[0022] Construction conditions:
[0023] 1) Material preparation:
[0024] Stone corner guard strip: The variety is white granite, and the specification is 50×20×1200 mm. (The length is adjusted according to the actual project). The surface is flamed, and the external corner is chamfered (R = 5 - 10 mm). Customized by the stone factory.
[0025] Cement mortar: Use 1:2.5 cement mortar, the cement is PO42.5, the sand is medium sand, and the mortar consistency is 30 - 40 mm.
[0026] 2) Tool preparation:
[0027] Infrared level, ink box, toothless saw, 1-meter spirit level, screed bar, tape measure, ash bucket, iron trowel, etc., sprayer.
[0028] 3) Measurement and setting out:
[0029] According to the 1-meter elevation control line of the wall surface and the designed ground elevation, in sequence, pop up the elevation line of the finished surface of the landing, the edge line of the landing, the inclined line of the stair section, the vertical grading control line of the outer corner of the step, and the horizontal line of the step riser.
[0030] Construction steps:
[0031] 1) Plastering of the landing
[0032] Based on the wall surface snap lines, make plastering control cakes on the landing to control the elevation of the landing. The elevation of the landing is taken as the key control point to avoid inconsistent elevations inside and outside the stairwell and large variations in the height of the stair steps.
[0033] Other construction contents such as cleaning, chiseling, wetting with water, slurry sweeping, and plastering finishing are not the key contents elaborated in this construction method and will not be described in detail.
[0034] 2) Plastering and pasting corner guards of the stair steps
[0035] For each flight of stairs, construct from bottom to top. First, construct the platform, and then construct the steps upward. When constructing the steps, first plaster the vertical surface, then press the stone corner guard on top, adjust the position to make the outer corner align with the line, then trim the vertical surface to make the corner guard fit tightly with the vertical surface mortar, and then plaster the tread surface based on the stone corner guard as the horizontal reference.
[0036] Carry out the first troweling when the cement mortar starts to set, and the second troweling before final setting. During the operation, the action should be gentle to avoid disturbing the stone corner guard and causing hollowing.
[0037] 3) Key construction techniques
[0038] The mortar consistency is 30 - 40 mm; the base layer is wetted with water in advance; the control lines are snapped on the wall surface; the surface of the stone is clean; after the construction of each step, avoid disturbing to prevent the stone corner guard from separating from the step mortar. Sprinkle water for curing after final setting, and the curing period is not less than 7 days.
