Construction method of large-span profile steel reinforced concrete beam
The invention discloses a construction method of a large-span profile steel reinforced concrete beam, which comprises the following steps that 1) a plurality of groups of scale guiding rule jacking pipe devices are installed on a bottom form of a to-be-installed profile steel reinforced concrete profile steel beam, and two scale guiding rule jacking pipe devices are oppositely arranged to form a group of supporting units; 2) the profile steel beam is hoisted to a position between the two scale guiding rule jacking pipe devices by adopting a crane, and an upper flange plate of the profile steelbeam is clamped by the scale guiding rule jacking pipe devices; 3) the scale guiding rule jacking pipe devices are jacked by adopting a jack, and the profile steel beam is driven to move to a specified position; 4) binding and welding are conducted on a bottom rib and a surface rib of the profile steel beam; 5) stirrups and stirrup lower cushion blocks are placed; and 6), after the crane is unloaded, a formwork is supported, and concrete is poured. For installation of a large-span profile steel reinforced concrete beam, the very good positioning, supporting and fixing effects are achieved, the structure is simple, a jacking pipe can achieve the very good supporting effect, the jacking position can be fixed according to needs, the construction efficiency is improved, and construction resources are saved.
本发明公开了一种大跨度型钢混凝土梁的施工方法，包括如下步骤：1）在待安装型钢混凝土型钢梁的底模上安装多组刻度靠尺顶升管装置，两个刻度靠尺顶升管装置相对设置形成一组支撑单元；2）采用起重机吊装型钢梁至两个刻度靠尺顶升管装置之间，将刻度靠尺顶升管装置卡紧型钢梁的上翼缘板；3）采用千斤顶对刻度靠尺顶升管装置进行顶升，带动型钢梁移动至指定位置；4）对型钢梁的底筋和面筋绑扎焊接；5）安放箍筋和箍筋下垫块；6）卸载起重机后，支护模板，浇筑混凝土。对于大跨度型钢混凝土梁的安装，具有很好的定位和支撑固定效果，结构简单，顶升管可以起到很好的支撑效果并能够根据需要固定顶托位置，提高了施工效率，节约了施工资源。
