Telescopic formwork support beam

Abstract

The invention discloses a telescopic formwork support beam. The telescopic formwork support beam comprises a sub beam, a main beam, ribs, pin bolts and pin holes, wherein the main beam is a ladder-shaped strip truss, upper and lower edges of the main beam are steel pipes, and the two steel pipes are fixedly connected by the ribs, and the tilting angles of the ribs on the two ends are equal; 6-10 axial equally-spaced pin holes are respectively arranged on the two ends of the upper and lower edges of the main beam, the sub beam is an open shaped frame, the upper and lower edges of the sub beam are steel pipes, and the outer end of the sub beam is fixedly connected by two tilting ribs along the same direction; the tilting angles of the ribs connected with the sub beam are equal to that of the ribs connected with two ends of the main beam; and the upper and lower edges of the open end of the sub beam are respectively axially inserted into pipes on the two ends of the main beam to form a nesting structure, and the sub beam is positioned relatively to the axial mounting position of the main beam by making the pin bolt traverse the pin hole. The telescopic formwork support beam is in a truss structure, the length of the beam is adjustable, and the structure strength is good; and during the mounting process, the mated vertical top brace is less, thus the auxiliary materials are saved, and the traffic space of the construction site is improved; and more importantly, the telescopic formwork support beam can be repeatedly used and the use cost can be saved.

Description

technical field [0001] The invention relates to a formwork for building construction, in particular to a formwork support beam for building construction. Background technique [0002] Casting in place is one of the main construction tasks in contemporary architectural engineering. The model built for the component to be poured must have a stable support. The support beam is a basic load-bearing component. In addition to rigidity and strength requirements, convenience for construction and installation and application cost must also be considered during fabrication. In today's engineering, steel pipes are generally used to build bent frames, and wooden squares or steel pipes are used as support beams on the bent frames. This kind of tailor-made support beams is accurate in size, installed in place, and reliable in support, which can meet the construction quality of on-site pouring. Require. However, the support beams fabricated on site in the project have disadvantages such ...

AI Technical Summary

Problems solved by technology

However, the support beams manufactured on site in the project have disadvantages such as large amount of materials, heavy weight, long manufacturing hours, non-adjustable length, and destructive demolition after use. These problems not only restrict the construction progress but also increase the construction cost.
