Embodiment Construction

[0027] refer to figure 1 , the present invention a kind of counterweight method of suspension platform, comprises the following steps:

[0028] A) Selection of counterweight area 3: after a certain distance from the beam end to the mid-span direction, the area within a certain range is the counterweight area;

[0029] B) Selection of the counterweight position in the counterweight area 3: carry out the counterweight on the flange plates 2 on both sides of the beam surface in the counterweight area 3;

[0030] C) counterweight: a suspension counterweight mechanism 1 is set on the two flange plates 2;

[0031] D) Counterweight limit: through the limit mechanism 4, the suspension counterweight mechanism 1 is horizontally limited.

[0032] The area within a certain range starting from the end of the transition section of the box chamber of the self-beam near the mid-span direction is the counterweight area 3 .

[0033] The area within 1 / 4 of the side span length is the counterw...

Abstract

The invention discloses a counterweight method of a suspension platform. The method comprises the following steps: A) counterweight area selecting: starting from a beam end to a certain distance in a midspan direction, and taking an area within a certain range as a counterweight area; B) counterweight position selection of the counterweight area: performing counterweight on flange plates on two sides of a beam surface in the counterweight area; C) counterweight: arranging suspension counterweight mechanisms on the two flange plates; and D) counterweight platform limiting: horizontally limiting the suspension counterweight mechanism through a limiting mechanism. Compared with the prior art, the bridge floor space can be saved, and subsequent construction is facilitated.

Description

【Technical field】 [0001] The invention relates to the technical field of box girder construction, in particular to the technical field of a counterweight method for a suspended platform. 【Background technique】 [0002] During the construction of the bridge erecting machine, due to the large load of the bridge erecting machine, excessive unbalanced bending moments will be generated on the beam body, and it is usually necessary to counterweight the bridge erecting machine at the side span. In addition, due to the progress of beam transportation, it is necessary to ensure that there is enough space for beam transportation on the bridge deck, and the traditional beam top counterweight is no longer applicable. 【Content of invention】 [0003] The purpose of the present invention is to solve the problems in the prior art, and propose a counterweight method for suspending the platform, which can save bridge deck space and facilitate subsequent construction. [0004] In order to a...
