Abstract
The invention relates to a foundation-free simple steel platform structure for operation in a bridge shallow water area, which comprises a pier through steel bar, a support bracket, a main longitudinal beam, a distribution beam, a steel plate and a Bailey beam support, wherein one end of the main longitudinal beam is erected on the support bracket on the pier through steel bar, the other end of the main longitudinal beam is erected on the Bailey beam support on a steel trestle, the distribution beam is paved on the two main longitudinal beams, and the steel plate is arranged on the distribution beam to form a working platform. The invention utilizes the penetrating steel bar on the pier stud to support one end of the platform, avoids the steel pipe pile foundation under the traditional steel platform, simplifies the construction method of the steel platform, saves the resource investment and saves the construction cost on the premise of meeting the site construction requirement and ensuring the construction safety.
Description
Technical Field
The invention relates to a bridge near-water construction steel platform, in particular to a foundation-free simple steel platform for shallow water construction.
Background
At present, for bridge wading construction, temporary bridges and steel platforms are mostly required to be erected to provide working platforms for construction. Steel pipe piles are typically selected for steel platforms to transmit loads to the concrete pile foundation. Some bridges are not influenced by water flow during the river dry season, and with the arrival of the flood season, a steel trestle and a steel platform need to be erected to solve the influence of the water flow on the operation. On the other hand, the construction of the bridge is greatly advanced, and the application of some advanced equipment reduces the requirements of the engineering on the area, the bearing and the like of the steel platform.
Disclosure of Invention
The invention provides a foundation-free simple steel platform structure for operation in a bridge shallow water area, which is simple in structure and clear in stress system; the main beam can be erected on a support bracket of the pier penetrating steel bar by adopting profile steel, so that the pier penetrating steel bar support bracket is strong in universality, less in resource investment, convenient to dismantle and capable of being used for multiple times.
In order to achieve the purpose, the technical scheme of the invention is as follows: the utility model provides a simple and easy steel platform structure of no basis of operation in shallow waters of bridge, includes pier cross-core rod iron, support "bracket", main longitudinal girder, distribution roof beam, steel sheet, "bailey" roof beam support, main longitudinal girder one end is taken and is established on support "bracket" on pier cross-core rod iron, and the other end is taken and is established on "bailey" roof beam support on the steel trestle, lays the distribution roof beam on two main longitudinal girders, and the distribution roof beam overhead steel sheet forms work platform.
The diameter of the pier penetrating steel bar is 90 mm-150 mm. The main longitudinal beam is H-shaped steel or I-shaped steel, and the length of the main longitudinal beam is 10 m-15 m.
The invention has the beneficial effects that: the invention utilizes the penetrating steel bar on the pier stud to support one end of the platform, avoids the steel pipe pile foundation under the traditional steel platform, simplifies the construction method of the steel platform, saves the resource investment and saves the construction cost on the premise of meeting the site construction requirement and ensuring the construction safety.

The distribution beam 4 is arranged on the two main longitudinal beams 3, the steel plate 5 serving as a panel is arranged on the distribution beam 4 and used as a construction platform, one end of each main longitudinal beam 3 is erected on the support bracket 2 on the pier stud penetrating steel bar 1, and the other end of each main longitudinal beam is erected on the Bailey beam support 6 on the steel trestle 7.
The diameter of the pier penetrating steel bar 1 is 90 mm-100 mm, the length of the main longitudinal beam 3 is 10 m-15 m, the distribution beam 4 can be channel steel or I-steel, and the support bracket 2 is formed by welding steel plates with the thickness of 2 cm.
The specific operation method of the invention comprises the following steps:
(1) when the pier 8 is constructed, 100mm PVC pipes are buried in the reserved holes according to the scheme, and after concrete is poured, the pier penetrating steel bar 1 can be conveniently penetrated for use.
(2) A support bracket 2 is welded on a pier penetrating steel bar 1 of a pier 8.
(3) A 'Bailey' beam support 6 is arranged on a well-erected steel trestle 7 and is fixed. And then installing the main longitudinal beam 3, and paving the distribution beam 4 and the steel plate 5 to form a construction platform.
(4) And (4) mounting a ladder cage on the construction platform, laying a concrete pump pipe, and constructing the upper structure of the bridge.
(5) And after the bridge construction is finished, dismantling the bridge according to the reverse sequence of erection.
