Background
In the process of building high-rise buildings or multi-story buildings, a stair mold is needed to manufacture stairs, the buildings with small construction amount are customized according to requirements, the repeated utilization rate is low, therefore, the cost for manufacturing the stair template by using the metal material is high, the wood mold is adopted in the actual construction process to carry out splicing type more use, however, in the splicing process by using the wood mold, due to the material problem of the wood mold, deformation is easy to occur in different modes of the splicing mode in the fixing process, so that the stair step has the construction quality problems of mold expansion, irregular yin and yang angles, poor verticality and the like during construction, in order to solve the partial deformation problem, the prior art Chinese patent CN 202882417U discloses a stair template structure, which is extruded in a limiting groove by arranging a limiting groove on a stair step side template and combining the limiting block, the deformation of the tread template is prevented, but the technical scheme has the following defects: 1, the thicknesses of the positioning block, the axe tip and the stepping template are only smaller than or equal to the width of the limiting groove, otherwise, the positioning block, the axe tip and the stepping template cannot be positioned in the limiting groove, and under the condition, the stepping template inevitably has local inclination or gaps, so that the problem of uneven poured stepping end surface and the problem of internal and external corners are caused; 2, if the thickness of the positioning block, the axe tip and the mark time template is larger than the width of the limit groove, and the positioning block, the axe tip and the mark time template are forcibly inserted into the limit groove, the notching part of the mark time side template at the side of the limit groove is inevitably deformed backwards or forwards, other mark time end faces are deformed, and under extreme conditions, the mark time side template is cracked, and the whole mold is scrapped.
Disclosure of Invention
For solving the defect that prior art exists, the utility model provides a stair are marked time and are prevented rising leak protection and strengthen template device can improve the problem that the mould expands is stepped on to the stair greatly to simple process need not consume extra building material resource.
In order to achieve the above purpose, the utility model adopts the following technical scheme: an anti-expansion and anti-leakage reinforced template device for stair treads comprises stair side templates and tread templates, wherein the stair side templates are provided with regularly arranged limiting grooves, the tread templates are inserted in the limiting grooves, and is fixed in the limit groove by extrusion of a limit device, the limit device comprises a first fixed plate, a second fixed plate and a wedge-shaped strip, the first fixing plate is positioned in the limit groove at the lower side end of the stepping template, a square wedge is arranged at the side end of the first fixing plate, the total thickness of the first fixing plate, the square wedge and the step template is equal to the thickness of the limiting groove, the second fixing plate is positioned at the side end of the stepping template above the first fixing plate, the wedge-shaped strip is positioned between the second fixing plate and the side wall of the limiting groove, the wedge-shaped strips are extruded downwards through the diameter difference of the wedge-shaped strips, and the upper parts of the second fixing plate and the step template are extruded in the limiting groove; the beneficial effects of this technical scheme lie in: the first fixing plate is positioned at the bottom, and in practice, even if the total thickness of the first fixing plate and the square wedge is slightly smaller than the residual width of the limiting groove, the lower part of the step template is only slightly wider, so that the walking form is met; because the second fixing plate is pushed downwards by the downward extrusion of the wedge-shaped strips and by utilizing the diameter difference of the wedge-shaped strips, the combination of the upper part of the tread template and the tread template is very tight, the condition of a concave-convex corner cannot occur, and the deformation cannot occur.
Preferably, the stair side template outside the limiting groove is provided with a reinforcing plate arranged along the limiting groove; the beneficial effects of this technical scheme lie in: the stair side template at the side end of the limiting groove is effectively prevented from being inclined forwards or backwards and cracking under the condition that the wedge-shaped strip is excessively extruded.
Preferably, the wedge-shaped strip is a triangular wedge-shaped strip; the beneficial effects of this technical scheme lie in: the triangular linear plane can be utilized to realize the attachment of one side end and the side wall of the stair side template at the side end of the second fixing plate or the limiting groove, and the downward smoothness is improved.
