Spoon-shaped steel formwork for junction part of elliptic cylinder and straight wall, formwork system and construction method

Abstract

The invention discloses a spoon-shaped steel formwork for a junction part of an elliptic cylinder and a straight wall, a formwork system and a construction method, and relates to the field of buildingconstruction. The spoon-shaped steel formwork for the junction part of the elliptic cylinder and the straight wall comprises a circular arc part and a junction part. The circular arc part is formed by a plurality of circular arc sections which are sequentially connected in the up-down direction; the junction part is formed by a plurality of junction sections which are sequentially connected in the up-down direction, each junction section comprises a junction plate, a second upper connecting plate horizontally connected to the upper edge of one side of the junction plate, a second lower connecting plate horizontally connected to the lower edge of one side of the junction plate, and second side connecting plates vertically connected to the two side edges of the junction plate; each junctionplate comprises a rectangular plate segment and a circular-arc-shaped plate segment, wherein the side edges of the rectangular plate segment and the side edge of the circular-arc-shaped plate segmentare in welded connection; and the bending radian of the circular arc part is consistent with the bending radian of the circular-arc-shaped plate segments of the junction part. The central angle corresponding to a circular arc of each circular-arc-shaped plate segment of the junction part is 19 degrees. The problems that the forming effect of circular arc parts of wood formworks assembled on siteis poor, and the force bearing performance of the structure cannot be well ensured through a rear bar planting mode are solved.

Description

technical field [0001] The invention relates to the field of building construction, in particular to a spoon-shaped steel formwork at the junction of an elliptical column and a straight wall, [0002] Formwork systems and construction methods. Background technique [0003] In the modern construction industry, it is often encountered that arc cylinders are connected to vertical components such as shear walls. This part is a key part of stress concentration and stress mutation. The construction quality of this part of the component has a great impact on the construction The mechanical performance has a great influence. There is currently no efficient and quality-guaranteed construction technology and formwork products for this working condition. Usually, there are two ways to meet the concrete components that are connected with special-shaped components and common components. One is to make special-shaped components or straight-section components first, and then plant reinfo...

Problems solved by technology

[0004] The purpose of the present invention is to provide a spoon-shaped steel formwork, a formwork system and a construction method at the junction of an elliptical column and a straight wall. It is necessary to solve the poor forming effect of the on-site assembled wooden formwork at the arc position, and the method of post-planting reinforcement cannot ensure the structure well.
