Tool type stair mold

Abstract

The invention provides a tool type stair mold. The tool type stair mold comprises a step mold assembly. The step mold assembly comprises a base plate. Step mold fixing positions are arranged on the base plate. A plurality of step molds which are closely arranged are detachably fixed on the step mold fixing positions. The base plate comprises a plurality of joint plates which are fixed together bybolts. Step mold fixing positions are arranged on the joint plates. At least one step mold can be fixed on each joint plate. Support frames are arranged on two sides of the base plate. Side sealing plates which can move in the width direction of the base plate are arranged on the support frames. The lower end edges of the side sealing plates are matched with the step molds. By the adoption of thestair mold, only the step molds need to be replaced, the number of the joint plates, the support frames and moving frames need to be increased or decreased and the matched side sealing plates need tobe replaced when the shape and size of a stair change; the combination of the plurality of parts can meet the requirements of a new design scheme; the universal rate of the parts is high; and waste ofthe molds after the design size is replaced is avoided.

Description

technical field [0001] The invention relates to the technical field of building construction, in particular to a tool-type staircase mold. Background technique [0002] With the development of modern industrial technology, building houses can be manufactured in batches and in sets by adopting prefabricated structures like machine production. Just transport the prefabricated building components to the construction site and assemble them. Greatly reduce on-site pouring operations. [0003] As an indispensable structure of a building, stairs can also be prefabricated in a factory and then assembled and installed. The molds used in the prefabrication of existing stairs are usually integral welded structures. A set of molds is made according to one size and model. The mold is dedicated to a fixed size and model, and cannot be used in multiple sizes and models. When pouring stairs with different heights and spans, Different molds need to be replaced, which increases the mold ma...

The molds used in the prefabrication of existing stairs are usually integral welded structures. A set of molds is made according to one size and model. The mold is dedicated to a fixed size and model, and cannot be used in multiple sizes and models. When pouring stairs with different heights and spans, Different molds need to be replaced, which increases the cost of mold making
