A modular self-adaptive door and window opening adjustable formwork system and its construction method

Abstract

A modular self-adaptive door and window opening adjustable formwork system and its construction method. The formwork unit includes an adjustable corner seat, an adjustable formwork and an adaptive support rod; The opening and closing angle is flexibly controlled by the angle adjustment rod to meet the requirements of various corner angles; the adjustable formwork is set between adjacent adjustable corner seats, which is an adjustable steel formwork; the self-adaptive support rod is set on the relative adjustable formwork Between them, the length is adjustable, forming a solid support for the adjustable formwork around; when the wall thickness is large, multiple formwork units can be arranged side by side to make the total thickness of the adjustable formwork system suitable for the wall. The present invention can adapt to the reserved formwork of any size of door and window openings through modular combination and adjustable components, can formwork with various angles and special shapes, and can also adapt to any wall thickness through combination. The construction method is simple and easy to operate, and can be turned over many times Using it can make the hole one-time forming and can guarantee the construction quality, improve the construction efficiency and save raw materials.

Description

technical field [0001] The invention relates to the technical field of adjustable formwork construction, in particular to an adaptive formwork system and a construction method for reserved construction of openings of doors and windows. Background technique [0002] In the construction of the main structure of buildings such as residential buildings, office buildings or commercial buildings, it is often necessary to reserve holes in the concrete walls for the configuration of doors and windows or strong and weak distribution boxes and other structures. At present, the construction of such openings generally uses traditional methods such as film-coated multi-layer boards as panels, wooden squares as keels, and adhesive tape on the surface for reserved construction. The adjustable formwork of this method can only be used once, and the adjustable formwork keel needs to be cut again when encountering different sizes and specifications, resulting in a great waste of materials.

Problems solved by technology

[0003] The purpose of the present invention is to provide a self-adaptive door and window opening reserved construction adjustable formwork system and its construction method, which solves the poor adjustability of the adjustable formwork existing in the current construction, and the adjustable formwork keels need to be cut separately in case of different sizes and specifications. The technical problems of great waste of materials and high cost, as well as the poor strength of the adjustable formwork will easily cause the concrete to expand after the concrete is poured, and the wall will easily have quality defects after the formwork is removed.
