Curved cast-in-place concrete beams and construction methods based on shaped quick-release aluminum formwork

Abstract

The invention relates to an arc-shaped cast-in-place concrete beam based on set-shaped and quick-disassembling aluminum formworks. The arc-shaped cast-in-place concrete beam is characterized in that transverse stiffening ribs and longitudinal groove type stiffening ribs are arranged on a beam outside formwork and a beam inside formwork; an upper edge rib aluminum plate is arranged on the beam inside formwork; a floor formwork is mounted on the upper edge rib aluminum plate; pin slots are formed in the transverse stiffening rib at the bottom, and pin joint structures are arranged in the corresponding pin slots; a beam bottom formwork is in pin joint with the beam outside formwork and the beam inside formwork; T-shaped fastening pieces are arranged at end parts of the beam outside formwork and the beam inside formwork, a fast support port is formed in the beam bottom formwork, a storage plate is arranged below the fast support port, and two pipe ribs are further arranged at the bottom of the beam bottom formwork. According to the structure and a construction method, location and construction quality of the arc-shaped beam formworks can be effectively controlled, economic efficiency and safety of construction are guaranteed, so that the formwork design is simple, convenient and fast, processing and mounting are convenient, and better economic and technical benefits are produced.

Description

technical field [0001] The invention relates to a construction method for an aluminum formwork arc-shaped cast-in-place beam, in particular to an arc-shaped cast-in-place concrete beam based on a shaped and quick-release aluminum formwork and a construction method. technical background [0002] In recent years, with the progress of society and the improvement of people's living standards, housing is no longer a simple residence, but a variety of buildings. Unique buildings abound, and architectural beauty often Reflected by curves, curved beams are often encountered in structural construction. If such curved beam formwork is improperly designed, it will result in high construction costs, long construction process time, and difficult construction quality assurance. [0003] The construction of reinforced concrete cast-in-place structures has always attached great importance to formwork engineering. In practice, the construction of curved beams in frame structure engineering, ...

AI Technical Summary

Problems solved by technology

The curvature of the curved beam changes a lot, which brings great difficulties to formwork design marking and processing of the curved formwork. Moreover, the curved formwork consumes a lot of materials and the construction cost is high.

At the same time, the construction flow of the normal floor structure is fast. If the curved edge beam is constructed with ready-made formwork, it will not be able to keep up with the construction flow of the structure, which will affect the construction progress of the overall structure.

The bamboo plywood commonly used at present has a smooth surface, easy demoulding, and elasticity, but it is not conducive to the accurate positioning of the curved beam side formwork

[0004] In view of this, it is urgent to invent a construction method for curved cast-in-place beams with fast construction speed, good construction quality, and rapid construction in view of the construction difficulties such as difficult control of the geometric size of the curved cast-in-place concrete beam formwork and complicated installation.
