Method for loading bridge support frame with prefabricated part

Abstract

The invention relates to a method for loading a bridge support frame with a prefabricated part, which is characterized by comprising the following steps: (1) producing a fabricated part which are provided with a horizontal groove and a vertical groove respectively on the upper surface and the lateral surface; (2) hoisting the prefabricated part on a bridge support frame of a first construction segment with a crane after construction of the bridge support frame, firstly paving a first-layer prefabricated part on the bridge support frame, then paving a second-layer prefabricated part on the first layer, and so forth till a design load weight of the bridge support frame of the first construction segment is achieved, passing through the horizontal groove with a horizontal wire rope to fasten a first hook on the prefabricated part of the same layer after each layer of prefabricated part is paved, and passing through the vertical groove with a vertical wire rope to fasten a second hook between the upper and lower adjacent prefabricated parts; and (3) moving the prefabricated part on the bridge support frame of the previous construction segment to the bridge support frame of the next construction segment for loading till the bridge support frame of the final construction segment is loaded. The invention has the characteristics of high efficiency, good safety and reusability of loading materials and prefabricated parts.

Description

technical field [0001] The invention belongs to the fields of civil engineering and bridge engineering, and in particular relates to a method for loading a bridge support frame. Background technique [0002] In order to ensure that the bridge support frame does not sink when the bridge slab is poured with concrete, it is often necessary to load the bridge support frame first after the bridge support frame is erected. The traditional method of loading the bridge support frame is to use the method of artificially stacking sand bags, which is simple and convenient. But there are also the following problems: 1. The bridge support frame is generally high, and the labor intensity of manual sand bagging is high; 2. The bridge support frame is characterized by long lines and large area, and the efficiency of manual sand bag stacking is low; 3. The specific gravity is small, so the sandbags occupy a lot of land and need to be stacked at a high height, making it more difficult to loa...

Problems solved by technology

But there are also the following problems: 1. The bridge support frame is generally high, and the labor intensity of manual sand bagging is high; 2. The bridge support frame is characterized by long lines and large area, and the efficiency of manual sand bag stacking is low; 3. The specific gravity is small, so the sandbags occupy a lot of land and need to be stacked at a high height, making it more difficult to load and unsafe; 4. Due to the high height of the pile, a large number of people pile sandbags at high altitudes, which is unsafe; 5. The progress is slow , will prolong the time of sealing the road, which is not good for residents to travel; 6. There is a gap between the sand bags, and the loading tonnage measurement is inaccurate
