Construction method for multi-layer concrete fold-line-shaped roof truss formwork pouring
The invention relates to the technical field of roof truss formwork installation, in particular to a construction method for pouring of a multi-layer concrete fold-line-shaped roof truss formwork. A roof truss formwork is preset on the ground and is made of thick steel plates, secondary keels and main keels are arranged on the outer side of the roof truss formwork, concrete is poured into the roof truss formwork, the distance between the upper surface of the concrete and the upper surface of the roof truss formwork is 50 mm, and a second-layer roof truss formwork is built on a formed first-layer fold-line-shaped roof truss; the steel roof truss formwork replaces a currently-adopted wooden formwork, the secondary keels and the main keels are arranged on the outer side of the steel roof truss formwork, formwork deformation is prevented, turnover is facilitated, the construction cost is reduced, and the quality of a fold-line-shaped roof truss is guaranteed; the clear distance between the main keels is controlled through the second locking nuts so that the width of the roof truss can be met; the height difference between the height of the roof truss formwork and the thickness of the fold-line-shaped roof truss is 50 mm, it can be guaranteed that the thickness of each layer of fold-line-shaped roof truss is the standard size in cooperation with the supporting blocks, and the roof truss formwork can be conveniently fixed through the supporting blocks.
本发明涉及屋架模板安装技术领域，具体是一种多层混凝土折线形屋架模板浇筑的施工方法。在地面上预设屋架模板，屋架模板由厚钢板制成，屋架模板外侧设置有次龙骨和主龙骨，在屋架模板内浇筑混凝土，混凝土上表面距离屋架模板上表面50mm，并在成型的第一层折线形屋架上搭建第二层屋架模板；钢制的屋架模板替换目前采用的木制模板，在外侧设置次龙骨和主龙骨，防止模板变形、利于周转、施工成本降低、保证折线形屋架质量，通过第二锁紧螺母控制主龙骨间的净距以满足屋架的宽度，利用第一锁紧螺母将主龙骨拧紧，通过屋架模板高度比折线形屋架厚度大50mm的高度差并搭配支撑块可以确保每一层折线形屋架的厚度为标准尺寸，并且通过支撑块方便屋架模板固定。
