Movable acrylic stair mold

Abstract

The invention relates to a movable acrylic stair mold. The movable acrylic stair mold is characterized in that a plurality of supports are vertically arranged on a base at intervals along the length direction of a stair, a plurality of cross beams are horizontally arranged on the supports in parallel, sliding grooves are formed in the cross beams, a plurality of adjusting seats are arranged on thecross beams, and adjusting bolts are screwed on the adjusting seats; and the adjusting bolts on every two adjacent adjusting seats vertically abut against the outer sides of the two vertical sides ofany L-shaped corner pipe plate, so that the L-shaped corner pipe plates are rotated, stretched and abutted against on the adjusting seats, the distance between the L-shaped corner pipe plates and back push plate members is adjusted, and the distance between any L-shaped corner pipe plate and the corresponding vertical edge of the next L-shaped corner pipe plate is adjusted. The mold has the advantages that the structure is compact and stable, the height of different steps can be met, span stairs can be poured, and the adjustment is convenient and rapid.

Description

technical field [0001] The invention relates to a staircase mold, in particular to a movable acrylic staircase mold. Background technique [0002] The stair construction of traditional stair steel mold building construction is divided into on-site pouring or prefabrication and on-site assembly. Due to the cumbersome assembly of molds for on-site pouring and long pouring and solidification period, it cannot meet the requirements of rapid construction. However, the molds used in the existing stair prefabrication are integral welded structures. , make a set of molds according to one size and model. The mold is dedicated to a fixed size and model. Most of the sealing plates in the concrete are made of wood and steel plates. The surface roughness of the wood and steel plates will affect the demoulding effect when the concrete is demoulded. At the same time, the steel plates are heavy and inconvenient for pouring and hoisting. Contents of the invention [0003] In view of the a...

[0002] The stair construction of traditional stair steel mold building construction is divided into on-site pouring or prefabrication and on-site assembly. Due to the cumbersome assembly of molds for on-site pouring and long pouring and solidification period, it cannot meet the requirements of rapid construction. However, the molds used in the existing stair prefabrication are integral welded structures. , make a set of molds according to one size and model. The mold is dedicated to a fixed size and model. Most of the sealing boards are made of wood and steel plates. The surface roughness of the wood and steel plates will affect the demoulding effect when the concrete is demoulded. At the same time, the weight of the steel plates is heavy, and it is inconvenient to pour and lift.
