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...

Examples

Embodiment 1

[0034] A method for loading a bridge support frame with prefabricated components, comprising the following steps:

[0035] 1) if figure 1 , figure 2 , image 3 As shown, the prefabricated component 1 is made, and the prefabricated component is block-shaped, and the upper surface of the prefabricated component is provided with horizontal grooves 2 that cross vertically and horizontally (that is, "ten" shape), and the intersection of horizontal grooves 2 (that is, the intersection of vertical and horizontal) place) is fixed with a first hook 3; the side of the prefabricated component is provided with a vertical groove 4 (the vertical groove is connected with the horizontal groove, and in this embodiment, the left and right sides are provided with vertical grooves), the vertical A second suspension hook 5 is fixed in the groove 4 (the second suspension hook is positioned at the middle part of the vertical groove);

[0036] 2) After the construction of the bridge support frame...

Embodiment 2

[0041] It is basically the same as Embodiment 1, except that the material of the prefabricated component is cast iron.

Embodiment 3

[0043] It is basically the same as Embodiment 1, except that the material of the prefabricated component is cast steel.
