Abstract
The utility model relates to a hanging construction platform for concatenation of steel box girder support method has articulated 3 at least montants on the steel box girder assembles the horizontal bridge of support to two adjacent and high level flat link rods respectively, and the montant symmetry that articulates on two flat link rods sets up, along a montant vertical interval welding bracket of vertical every, sets up a supporting beam between two high brackets of equal height on two relative montants in the same direction as the bridge, lays the platform panel on the supporting beam. The utility model discloses platform height-adjustable adopts the assembled structure, and installation and dismantlement are fast, and material reuse rate is high.
Description
Technical Field
The utility model relates to a construction technical field is assembled to bridge steel case roof beam, concretely relates to hanging welding operation platform that is used for construction is assembled to steel case roof beam support method festival section.
Background
The steel structure bridge is usually constructed by adopting a support method when steel box girders are spliced, supports are erected between piers, a plurality of prefabricated steel box girder segments are hung on the supports, and constructors weld the end parts of the adjacent steel box girders. During construction, a construction platform needs to be arranged on the support, and the height of the platform is usually set according to the height of a welder. The common construction platforms are welded on the support, once the construction platforms are arranged, the height of the construction platforms is fixed, and in the process of assembling and welding the steel box girder, the height of a welding part is changed, and in addition, the change of workers is large, and the operation platform with the fixed height brings inconvenience to construction; and the platform needs to be cut when being disassembled, so that the support and the platform material are damaged, and the material reuse rate is influenced.
Disclosure of Invention
The utility model aims at providing a hanging construction platform to the above-mentioned problem that present steel box girder welding construction platform exists, do not need the welding to fix on the support to platform height-adjustable, convenient construction.
The technical scheme of the utility model as follows:
the utility model provides a hanging construction platform that is used for steel box girder support method to splice which characterized in that: at least 3 vertical rods are respectively hung on two adjacent horizontal connecting rods with the same height in the transverse bridge direction of the steel box girder assembling support, the vertical rods hung on the two horizontal connecting rods are symmetrically arranged, a bracket is welded on each vertical rod at certain intervals along the longitudinal direction of the vertical rod, a supporting beam is erected between the brackets with the same height on two vertical rods opposite to the bridge direction, and a platform panel is laid on the supporting beam.
The utility model is a rod type assembly structure, which occupies smaller space when being stored, does not need welding construction when being installed, only needs to hang the vertical rod on the flat link rod of the bracket, screws up the fixing bolt, then sets up the beam on the bracket, and then lays the upper panel, thus completing the installation of the welding operation platform; in the welding operation process of the steel box girder, the cross girder can be erected on a bracket with a proper height on the vertical pole according to the operation height and the height of a welder, so that the height of the welding operation platform can be adjusted; when the platform is disassembled, the support structure and the platform component can not be damaged, the repeated utilization rate of materials is improved, and the construction cost is saved.

Detailed Description
As shown in fig. 1, fig. 2 and fig. 3, the utility model discloses it has 3 at least montants 3 to articulate respectively on two adjacent and equal-height flat connecting rods 2 of support 1 cross bridge assembled at the steel box girder, and the 3 symmetry settings of montant that articulate on two flat connecting rods 2, along a montant longitudinal interval welding bracket 4 of vertical every on every montant 3, set up a supporting beam 5 between two equal-height brackets 4 on two relative montants in the same direction as the bridge supporting beam upper berth is equipped with platform panel 6.
The structure of the vertical rods 3 is as shown in fig. 4, a buckle 31 is arranged at the upper end of each vertical rod 3, and the buckle 31 is a frame-shaped structure with an opening at one side. The buckle card is on the support parallel connection, and fixing bolt 32 has been inserted between the upper and lower limit of buckle opening side.
The utility model discloses during the implementation, for guaranteeing a supporting beam stability, be equipped with the limiting plate 41 that makes progress outstanding in 4 both sides of every bracket, a supporting beam 5's tip supports at 4 top surfaces of bracket and inject between two limiting plates 41.
As shown in fig. 5, the utility model discloses during the installation, with the buckle card of every montant 3 upper end on the flat link rod 2 of support 1 is assembled to the steel box girder, preset the screw to wearing on buckle opening side's roof and the bottom plate, insert the bolt in the screw and screw up the nut at the bolt both ends, fix the montant on flat link rod. According to the height of the welding part of the steel box girder 7 and the height of constructors, a support beam 5 is selected to be erected on a bracket 4 with a proper height, and then a panel is laid on the support beam, so that the platform installation is completed. When the height of the platform needs to be adjusted, the supporting beams are adjusted to be supported on the other pair of brackets, and the panels are paved again. After the welding construction of the steel box girder of one construction point is completed, the platform can be disassembled and installed to the next construction point for continuous construction.
