Pedestrian overpass UHPC prefabricated stair board production and hoisting splicing construction process
The invention discloses a pedestrian overpass UHPC prefabricated stair board production and hoisting splicing construction process which specifically comprises the following steps: S1, taking UHPC as a raw material, doping water and an additive, and stirring and mixing to obtain a UHPC pouring material; s2, UHPC prefabricated stair components are manufactured; s3, according to the structural characteristics of the prefabricated stair component, a hoisting point is arranged; s4, hoisting equipment is adopted for hoisting the prefabricated stair component; the invention relates to the technical field of prefabricated stair plates. According to the production and hoisting splicing construction process for the UHPC prefabricated stair board of the pedestrian overpass, the characteristics of the UHPC material are combined, traditional concrete stirring equipment is properly improved, whole-process fine monitoring is carried out on stirring of the UHPC material, parameters such as the stirring time, the stirring speed, the water consumption, the admixture dosage and the steel fiber dosage of a mixture are strictly controlled, and the production efficiency of the UHPC prefabricated stair board is greatly improved. And the UHPC mixture with various indexes meeting theoretical specification requirements is produced, so that the production and manufacturing requirements of prefabricated parts are met.
本发明公开了人行天桥UHPC预制楼梯板生产及吊装拼接施工工艺，具体包括如下步骤：S1、以UHPC作为原材料，掺入水及外加剂，搅拌混合，得到UHPC浇筑材料；S2、制作UHPC预制楼梯构件；S3、根据预制楼梯构件的构造特点，设置吊装点；S4、采用起重设备对预制楼梯构件进行吊装；本发明涉及预制楼梯板技术领域。该人行天桥UHPC预制楼梯板生产及吊装拼接施工工艺，结合UHPC材料特性，对传统混凝土搅拌设备进行适当改良，对UHPC材料搅拌实施全过程精细化监控，严格控制混合料搅拌时间、搅拌速率、用水量、外加剂摻量、钢纤维掺量等参数，生产出各项指标满足理论规范要求的UHPC混合料，以满足预制构件生产制作需求。
