Long corridor floor support-free aluminum plastic formwork device

Abstract

The invention discloses a long corridor floor support-free aluminum plastic formwork device which comprises at least oneformwork unit, each formwork unit comprises two transverse side ribs, two longitudinal side ribs and a bottom plate, and the two transverse side ribs and the two longitudinal side ribs are sequentially connected at intervals to form a square frame structure in an enclosing mode; a longitudinal edge rib on one side of the frame structure is connected with the lower end of a beam formwork device, and a longitudinal edge rib on the other side of the frame structure is connected with the upper end of a wall column formwork device; the bottom plate is fixed to the bottom of the frame structure, and a pouring cavity is formed between the upper surface of the bottom plate and the inner wall of the frame structure; the transverse side ribs and the longitudinal side ribs are respectively made of aluminum profiles; and the bottom plate is made of a plastic material. The formwork device has the beneficial effects that the formwork units are of frame structures made of aluminum profiles, the bottom plates are made of plastic materials, the dead weight of the formwork device is greatly reduced, a vertical supporting vertical rod does not need to be adopted, the formwork device is suitable for a structural system with the large length-width ratio, the structure is simple, and the construction efficiency is greatly improved.

Description

technical field [0001] The invention relates to the field of building construction, in particular to a support-free aluminum-plastic mold device for floor slabs in long corridors. Background technique [0002] Aluminum alloy formwork is a metal formwork used for concrete pouring and forming. The aluminum alloy formwork has a simple reinforcement system, high component strength, large combination rigidity, high plate production precision, tight joints, not easy to deform, good formwork integrity, and strong shock resistance. , can be used multiple times, has many turnover times, and has the characteristics of beautiful concrete pouring and molding, and is widely used in construction projects. However, the traditional all-aluminum alloy formwork is heavier than the plastic formwork, so the floor formwork must require vertical support poles. For the narrow and long structural system of the corridor floor, the traditional formwork needs to be equipped with two vertical poles as...

Problems solved by technology

For the narrow and long structural system of the corridor floor, the traditional formwork needs to be equipped with two vertical poles as vertical supports, which will easily lead to narrow construction passages, reduce the efficiency of material transmission, increase the difficulty of construction personnel to pass through, and make the overall construction more difficult; And because the distance between the two poles vertically supporting the traditional long corridor is relatively close in the short side direction, forming a support system with a large slenderness ratio, in order to ensure stability, it is necessary to add horizontal poles to connect the poles with the surrounding wall columns or poles. The connection is fixed, adding extra measures
