Fig. 3 is a K-way partial view of fig. 2.
The symbols in the drawings illustrate that: the stair comprises stair side templates 1, limiting grooves 2, step templates 3, square wood back ridges 4, axe tips 5, step template bottom lines 6, step vertical stepping lines 7, step top surfaces 8, template bracing strips 9, step width A, step height B, height difference S and limiting groove width L.
Detailed Description
The present invention will be described in detail with reference to the following preferred embodiments.
As shown in fig. 1-3, a structure for limiting and installing the grooves of the stair step template comprises a stair side template 1, wherein the stair side template 1 is provided with a limiting groove 2, the front side edge of the limiting groove 2 coincides with a step vertical stepping line 7 of a stair, the bottom surface of the limiting groove inclines towards the front side, and the height difference S between the front end and the rear end of the bottom surface of the limiting groove is 20-30 mm. Template 3 of marking time sets up in spacing recess 2 inside front position, and spacing recess 2 rear side is provided with square timber back of the body stupefied 4, and square timber back of the body stupefied 4 rear side sets up axe point 5, and axe point 5 is the triangle-shaped structure, and axe point 5 is inserted and is pushed up square timber back of the body stupefied 4 and template 3 of marking time tightly in spacing recess 2. The front side of the limiting groove 2 coincides with a step vertical stepping line 7 of the stair, and the front end of the bottom surface of the limiting groove 2 coincides with a step top surface 8 of the stair. The width L of the limiting groove is 120-150 mm.
The utility model adopts the steps of sawing a limiting groove on the side template of the stair, placing the step template in the groove, tightly pointing the step template in place by using an axe, and achieving the effects of accurate installation and positioning of the step template, no deformation and no sinking by utilizing the limiting effect of the groove.
The method for building and laying the bottom template of the stair support is the same as the conventional construction method, but the horizontal height difference of the same position at the two sides of the bottom template is strictly controlled, and the height difference cannot exceed 3 mm.
On the stair side plate template, according to the size and the height of stair marking time, the bottom line and the vertical stepping line of the marking time template are popped up, then a limiting groove is sawn according to the bottom line and the vertical line, the width of the limiting groove is 120-150 mm, the bottom of the limiting groove inclines 20-30 mm to the side of the marking time template, and the marking time template can be conveniently installed and smoothly placed in place. As shown in fig. 1.
