Arching device for large-span beam and construction method
An arching device for a large-span beam comprises a screw rod and a sleeve and is characterized in that the size of the screw rod is 100 * 100 * 5mm, a top plate is fixedly welded to the center of the top end of the screw rod and is perpendicular to the screw rod, and an E-shaped clamping hoop is movably arranged at the bottom end of the screw rod and is locked through a nut; the sleeve is a galvanized steel pipe, the sleeve sleeves the outer side of the middle part of the screw rod, and the arching value of the large-span beam is adjusted by using the length of the sleeve; steel pipes are clamped on the two sides of the mountain-shaped clamping hoop respectively, so that the two steel pipes are arranged on the two sides of the bottom of the casing pipe. The arching device for the large-span beam and the construction method have the advantages that the beam arching device is simple in structure and convenient to manufacture, the quality problems of concrete cracks, impressions and the like caused by drooping of a formwork support and overlarge deflection in the pouring process of the large-span beam are solved, the arching height of the beam arching device is convenient to control, and the construction efficiency is improved. The construction efficiency is high; and the construction progress is fast.
一种用于大跨度梁的起拱装置，包括螺杆、套管，其特征在于：所述螺杆的尺寸为100x100x5mm，螺杆的顶端中心固焊有顶板，顶板与螺杆垂直，螺杆的底端活动设有山型卡箍，山型卡箍由螺母锁紧；所述套管为镀锌钢管，套管套合在螺杆的中部外侧，并用套管长度调节大跨度梁起拱值；其中：山型卡箍的两侧分别夹有钢管，使两根钢管置于套管底部两侧。本发明的用于大跨度梁的起拱装置及施工方法具有梁起拱装置结构简单、制作方便，解决大跨度梁在浇筑过程中模板支撑下垂、挠度过大引起的混凝土裂纹及观感等质量问题，梁起拱装置起拱高度控制方便，施工效率高和施工进度快的优点。
