Cross beam formwork support and design and construction method thereof

Abstract

The invention relates to the technical field of design and construction of building structure formwork supports, in particular to a cross beam formwork support and a design and construction method thereof. The design and construction method includes the following steps: firstly, a construction drawing of the cross beam formwork support is designed; secondly, checking of the bearing capacity is conducted; thirdly, the construction drawing is adjusted; fourthly, a beam bottom formwork tray is produced; fifthly, positioning and laying off of vertical rods are conducted; sixthly, a beam bottom formwork support is erected; seventhly, a beam bottom adjustable supporting brace is installed; eighthly, the beam bottom formwork tray is installed; ninthly, a beam bottom formwork main edge is installed; tenthly, beam bottom formwork secondary edges are installed; eleventhly, a beam bottom formwork panel is installed; and twelfth, cross beam reinforcement binding and beam side formwork installationare conducted. According to the cross beam formwork support and the design and construction method thereof, the key technical difficult problem of the vertical and horizontal cross beam bottom formwork main edge elevation difference can be effectively solved, the erection speed of the cross beam formwork support is increased 3 times than that of traditional technologies, factory processing and assembly construction of the beam bottom formwork tray are achieved, the beam bottom formwork tray is recycled hundreds of times, the comprehensive cost of construction can be greatly saved, and the requirements of energy conservation and consumption reduction and green construction are met.

Description

technical field [0001] The invention provides a well-shaped beam formwork support and a design and construction method thereof, which belong to the technical field of design and construction of building structure formwork supports, and are suitable for the design and construction of well-shaped beam formwork supports of various cross-sections and spans. Background technique [0002] In recent years, in order to meet the needs of shared large spaces such as film and television halls, conference rooms, and exhibition halls, there have been more and more structural designs of well-shaped beam buildings (roofs). However, the longitudinal horizontal rods under the beams of the traditional formwork support overlap at the crossing area of ​​the vertical and horizontal well-shaped beams, resulting in a height difference between the main flutes of the bottom formwork of the vertical and horizontal well-shaped beams. The main flute of the well-shaped beam bottom formwork in the direct...

AI Technical Summary

Problems solved by technology

However, the longitudinal horizontal rods under the beams of the traditional formwork support overlap at the crossing area of ​​the vertical and horizontal well-shaped beams, resulting in a height difference between the main flutes of the bottom formwork of the vertical and horizontal well-shaped beams. Square timber is fixed and leveled with steel nails for the main flute of the well-shaped beam bottom formwork in the direction

Not only is the construction difficult, the lining square timber is wasted, the main flute of the beam bottom formwork is damaged, and the construction period is affected, but the main flute of the beam bottom formwork after the lining is leveled is very unstable, causing the concrete at the bottom of the beam to bend; The bearing capacity of the second formwork does not meet the requirements, resulting in the cracking of the concrete of the well-shaped beam and affecting the bearing capacity and durability of the structure
