Description

Technical Field

[0001] The invention relates to the technical field of bridge construction, and in particular to a synchronous construction device and a construction method for a main beam of a cable-stayed bridge with a reduced-scale simulation. Background Art

[0002] A cable-stayed bridge, also known as a cable-tensioned bridge, is a type of bridge in which the main beam is directly pulled on the bridge tower by many cables. It is a structural system composed of a pressure-bearing tower, tensioned cables and a bending beam. As a cable system, the cable-stayed bridge has a greater span capacity than a beam bridge and is the main type of long-span bridge. A cable-stayed bridge is composed of many steel cables directly connected to the tower to lift the bridge deck. It is mainly composed of a main tower, a main beam and cable-stayed cables.

[0003] When constructing a cable-stayed bridge, the general construction method is to construct the main tower first, and then construct the main beam after the main tower construction is completed.

[0037] The construction method of the scaled simulation cable-stayed bridge cable main tower main beam synchronous construction device comprises the following steps:

[0038] S. Construction equipment installation:

[0040] S. Adjustment of the horizontal construction hanging basket position:

[0041] After the installation of the horizontal construction hanging basket is completed, the first electric push rod is controlled to work, and the first electric push rod can drive the horizontal fixing seat to rise and fall, thereby driving the horizontal construction hanging basket to rise and fall, and adjusting the height of the horizontal construction hanging basket;

[0042] By controlling the first driving member to work, the first driving member can drive the first threaded rod to rotate, and when the first threaded rod rotates, the first slider can be driven to move inside the first slide slot, and when the first slider moves, the horizontal construction hanging basket can be driven to move through the first connecting rod, and the position of the horizontal construction hanging basket can be adjusted, so as to facilitate the subsequent construction of the cables on both sides of the main beam;

That is, when the horizontal construction basket moves a certain distance, the vertical construction basket rises a certain distance, that is, when the main beam is constructed for a certain length, the main tower can be constructed to a certain height. At the same time, when the main tower and main beam are under construction, the movable horizontal construction basket and the vertical construction basket are used to realize the construction of the cables on both sides, thereby realizing the synchronous construction of the cables, main tower and main beam on one side of the cable-stayed bridge. Finally, the synchronous construction of the cables, main tower and main beam on the other side of the cable-stayed bridge is completed in the same way.

Due to the synchronous construction, the construction steps are shortened, time is saved, and construction efficiency is improved. At the same time, fewer construction auxiliary devices are used, material consumption is reduced, and it is beneficial to reduce construction costs.

That is, when the horizontal construction basket 21 moves a certain distance, the vertical construction basket 30 rises a certain distance, that is, when the main beam is constructed for a certain length, the main tower can be constructed for a certain height. At the same time, when the main tower and the main beam are constructed, the movable horizontal construction basket 21 and the vertical construction basket 30 are used to realize the construction of the cables on both sides, thereby realizing the synchronous construction of the cables, the main tower and the main beam.

[0107] The specific working process of the present invention is as follows:

[0108] When constructing a cable-stayed bridge, the construction device needs to be constructed first. Before the main tower and main beam are synchronously constructed, the base 11 is constructed at a suitable position, the vertical mounting frame 22 is fixedly mounted on one side of the upper end of the horizontal mounting frame 12, the main beam construction assembly is mounted on the horizontal mounting frame 12, the main tower construction assembly is mounted on the vertical mounting frame 22, and the synchronous drive assembly is installed between the horizontal mounting frame 12 and the vertical mounting frame 22. Finally, the horizontal mounting frame 12 is fixedly mounted on the top of the multiple groups of bases 11, thereby completing the construction of the construction device;

[0109] Subsequently, when the cable-stayed bridge is being built, the third electric push rod 34 works, and the third electric push rod 34 drives the horizontal slide plate 14 to move to the side away from the vertical mounting frame 22, so as to realize the horizontal laying construction of the main beam. At the same time, when the horizontal slide plate 14 moves, the vertical slide plate 24 can be driven to move upwards through the first guide wheel 31, the second guide wheel 32 and the steel rope 33, so as to realize the vertical construction of the main tower, that is, when the horizontal construction hanging basket 21 moves a certain distance, the vertical construction hanging basket 30 rises a certain distance, that is, when the main beam is constructed for a certain length, the main tower can be constructed for a certain height;

[0110] At the same time, when the main tower and the main beam are under construction, the first electric push rod 17 is controlled to work, and the first electric push rod 17 can drive the horizontal fixing seat 43 to rise and fall, thereby driving the horizontal construction hanging basket 21 to rise and fall, and adjusting the height of the horizontal construction hanging basket 21; by controlling the first driving member 19 to work, the first driving member 19 can drive the first threaded rod 18 to rotate, and when the first threaded rod 18 rotates, it can drive the first slider 16 to move inside the first slide groove 15, and when the first slider 16 moves, it can drive the horizontal construction hanging basket 21 to move through the first connecting rod 20, and adjust the position of the horizontal construction hanging basket 21, so as to facilitate the subsequent construction of the cables on both sides of the main beam;

[0111] The second electric push rod 27 is controlled to work, and the second electric push rod 27 can drive the vertical fixing seat 44 to move. The vertical fixing seat 44 can adjust the distance between the vertical construction hanging basket 30 and the main tower when it moves; the second driving member 45 is controlled to work, and the second driving member 45 can drive the second threaded rod 28 to rotate. When the second threaded rod 28 rotates, it can drive the second slider 26 to move inside the second slide groove 25. When the second slider 26 moves, it can drive the vertical construction hanging basket 30 to move through the second connecting rod 29, and adjust the position of the vertical construction hanging basket 30, so as to facilitate the subsequent construction of the cables on both sides of the main tower;

[0112] The movable horizontal construction hanging basket 21 and the vertical construction hanging basket 30 are used to realize the construction of the cables on both sides, thereby realizing the synchronous construction of the cables, the main tower and the main beam;

[0113] Finally, the same method is used to complete the synchronous construction of the cables, main towers and main beams on the other side of the cable-stayed bridge. Example

[0114] In order to ensure the safety of the construction workers, a protective net is set on the outside of the horizontal construction hanging basket 21 and the vertical construction hanging basket 30, so that the horizontal construction hanging basket 21 and the vertical construction hanging basket 30 are in a fully enclosed state to ensure the safety of the construction workers. At the same time, a layer of dense mesh can be set on the outside of the protective net to prevent small objects or tools from falling from the horizontal construction hanging basket 21 or the vertical construction hanging basket 30, and a safe passage can be built on the main beam after the construction is completed for the construction workers to pass through, further increasing the protection effect of the device.
