An integral staircase mold and its construction method

Abstract

An integral staircase mold and its construction method, the mold includes a stepped panel, a strip side panel, a channel steel connecting strip, a channel steel dragon frame, a lifting ring, an anchor hoop, an air vent, a vibrating hole, and a pouring port . The construction method includes the following steps: (1) making the integral staircase mold according to the design size of the stair treads; (2) hoisting the integral staircase mold on the formwork at the bottom of the stairs; (3) continuously pouring concrete from the pouring port , Vibrate while pouring until the pouring is full; (4) After the concrete reaches the specified strength, untie the fastening wire rods of the 4 anchor hoops, and lift the integral staircase mold. The invention can continuously pour concrete at one time, the construction method is simple, and the quality is easy to control, and the integral staircase mold has high rigidity, durability, can be used for multiple turnovers after one input, the mold is assembled and disassembled, and the operation is simple.

Description

technical field [0001] The invention relates to the field of building molds, in particular to an integral staircase mold and a construction method thereof. Background technique [0002] 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 st...

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
