Mold for stair step making

Abstract

The invention relates to technical field of building construction, and specifically discloses a mold for stair step making. The mold includes two parallel inclined bars; multiple main keels are detachably fixed on the inclined bars; the spacing distances between the main keels are equal to the spacing distances between stairs; kick plates are fixed on the main keels; vertical reinforcing steel pipes are fixed on the two sides of the inclined bars; and bar-shaped side plates are fixed on the vertical reinforcing steel pipes. The advantages of the mold are as follows: one-time pouring of stairsat stair sections can be realized through the mole; and the mold is convenient in usage and good in stair construction quality.

Description

technical field [0001] The invention relates to the technical field of building construction, in particular to a mold for making stair steps. Background technique [0002] At present, in the process of stair construction, stair treads and structural slabs are generally divided into the same construction section. When pouring concrete, because the stair section is more complicated than the slab, the slab is usually poured first, and then the stair tread is poured. Therefore, the setting time of the concrete of the stair tread is always slower than that of the slab concrete. When the slab concrete reaches the upper strength, the stair tread will However, people could not go up, which seriously delayed the construction; because the steps of the stairs are at different elevations, the concrete has fluidity. During the pouring process, under the action of gravity, the concrete easily flows out of the formwork and is not easy to control. Therefore, the concrete pouring of the stai...

When pouring concrete, because the stair section is more complicated than the slab, the slab is usually poured first, and then the stair tread is poured. Therefore, the setting time of the concrete of the stair tread is always slower than that of the slab concrete. When the slab concrete reaches the upper strength, the stair tread will However, people could not go up, which seriously delayed the construction; because the steps of the stairs are at different elevations, the concrete has fluidity. During the pouring process, under the action of gravity, the concrete easily flows out of the formwork and is not easy to control. Therefore, the concrete pouring of the stairs is intermittent and cannot be continuously constructed. Time-consuming and labor-intensive; the staircase is a passage for people and materials, and the finished product is easily damaged due to the concentration of people in the past; missing corners and potholes on the stairs are the biggest problems in the protection of the finished staircase
