Detailed Description

In order to make the technical means, creation features, achievement purposes and functions of the present invention easy to understand, the present invention is further described below with reference to the following embodiments.

As shown in fig. 1 to 2, a concrete stair template comprises a stair bottom die 1, a pull-insert type material cleaning port 2, a stair width positioning batten 3, a stair side die 4, a side template back ridge 5, a side template U-shaped clamping groove 6, a riser template 7 and a split bolt 8; stair side forms 4 are installed on 1 both sides of stair die block, and stair width is injectd to stair width location flitch 3 in both sides on the stair die block 1, and U type draw-in groove is seted up to stair side forms 4, and the outside sets up the stupefied 5 of side form back of the body, and in the U type draw-in groove of stair side forms 4 was inserted to kick template 7, kick template 7 was fixed by two built-in flitch fossil fragments of two blocks of former blocks back and forth, and the space is established to the staying in the middle of the flitch, and split screw 8 fastens stair side forms 4 with the fossil fragments.

Specifically, a drawing and inserting type material cleaning port 2 with the width of 50mm is arranged at the position 11/3 of the stair bottom die.

Specifically, the stair bottom die 1 comprises a stair bottom plate, the lower portion of the bottom plate adopts 40-80 battens as bottom back ridges, and two sides of the bottom plate adopt 40-40 battens to limit the width of the stair and serve as side formwork back ridges 5.

Specifically, the distance between the opposite pulling screws 8 is not more than 1000mm or two steps are arranged at intervals.

Specifically, the skirting board template 7 is formed by fixedly arranging two batten keels in a front wood template and a rear wood template, and a gap of 3cm-5cm is reserved between the battens.

The working process and principle are as follows: after the stair template support frame is installed and leveled, a stair bottom plate is firstly placed, the lower part of the bottom plate adopts 40-80 battens @200 back ridges, the width of the stair is limited by 40-40 battens on two sides of the bottom plate, the stair bottom plate also serves as the back ridges of the side template, and a stair construction joint at 1/3 of the bottom plate) is provided with a 50mm wide discharge port and can be manufactured by drawing a batten); secondly, installing a stair side template, determining the horizontal position of a stair kickplate by the side template according to the cross section size of the stair step, cutting a U-shaped clamping groove with the width of 70mm, and improving the rigidity of the side template by adopting 40-40 battens and 40-80 battens as back ridges on the outer side of the side template; inserting the skirting template into the U-shaped clamping groove of the side template, wherein the skirting template is formed by fixedly arranging two batten keels in the front and rear two wood templates, a gap of 3-5 cm is reserved between the battens so as to conveniently penetrate through a split bolt to clamp the skirting panel, the front and rear template surfaces are used in turn, the turnover rate of the skirting template is ensured, the length of the template is equal to that of the stair step skirting surface, and the height of the template is equal to that of the stair step skirting surface; and finally, the side die is relatively fastened by adopting a pair of pull screws with the diameter of 14 and a wood keel, the distance between the pair of pull screws is not more than 1000mm or two steps are arranged at intervals, and the side formwork and the skirting formwork are ensured not to displace.

Based on the above, the structure of the utility model adopts the novel assembled stair template, which can be used in a whole building all the time, increasing the turnover times of the template, the construction can be carried out for 60 times, and the turnover times of the general wooden template are 8 times; the installation is simple, the disassembly is convenient, the labor cost is reduced, and the working efficiency is improved; the problem of mixing of the stair concrete construction joint is avoided, and the quality of concrete is ensured; the common quality problems of overlarge cross section size and elevation deviation of the stair component, unsmooth and straight stepping internal and external corners and the like can be completely eliminated.
