Abstract
The utility model relates to a pedestal is assembled to steel case arch rib festival section, including many stands that support on concrete foundation, many stands transversely are provided with the multirow along the pedestal, and the spandrel girder has been set up at every row of stand top, and every spandrel girder both ends set up a reaction frame respectively, and the reaction frame includes montant and diagonal brace, and the montant is equipped with supporting platform towards one side take the altitude department in the middle of the spandrel girder, is equipped with horizontal jack on the supporting platform, lies in a plurality of sliding cushion of equidistance welding between two reaction frames on the spandrel girder. The utility model discloses a jack top pushes away the arch rib festival section and carries out position adjustment, can effectively reduce intensity of labour, and the cushion that slides simultaneously can reduce the frictional force of arch rib festival section bottom, makes the arch rib festival section remove easier to avoid causing the damage to the arch rib structure.
Description
Technical Field
The utility model relates to a steel case arched bridge construction technical field, concretely relates to pedestal that is used for steel case arch rib to assemble.
Background
The main arch rib of the steel box arch bridge adopts a box-shaped section, is generally processed in a section mode in a factory and is transported to a construction site for assembly. Because the arch rib line shape is arc, the requirement on the seam precision is higher during assembly. At present, when assembling construction is carried out, the arch rib segments are firstly hoisted on the pedestal by large-scale hoisting equipment, and the swing amplitude is large when the crane hoists, so that the positions of the arch rib segments need to be manually pushed and adjusted, the labor intensity is high, and the butt joint precision is not easy to control.
Disclosure of Invention
The utility model aims at the above-mentioned problem, improve the pedestal is assembled to current steel box arch rib festival section, reduce constructor intensity of labour to improve the arch rib festival section and assemble the precision.
The technical scheme of the utility model as follows:
the utility model provides a pedestal is assembled to steel case arch rib section, includes that many support the stand on concrete foundation, many stands transversely are provided with the multirow along the stand, and spandrel girder, its characterized in that have been set up at every row of stand top: the two ends of each bearing beam are respectively provided with a reaction frame, each reaction frame comprises a vertical rod, the lower end of each vertical rod is welded with the corresponding bearing beam, an inclined supporting rod is welded between each vertical rod and the end part of each bearing beam, a supporting platform is arranged at a position, facing the middle of each bearing beam, of each vertical rod at a certain height, and a transverse jack is arranged on each supporting platform; a plurality of sliding cushion blocks are welded between the two reaction frames at equal intervals on the bearing beam.
The utility model discloses establish the jack in pedestal both sides, establish the cushion that slides at pedestal supporting beam top surface, push away through the jack and remove about the arch rib festival section and carry out position adjustment, can effectively reduce intensity of labour, the cushion that slides simultaneously can reduce the frictional force of arch rib festival section bottom, makes the arch rib festival section remove easier to avoid causing the damage to arch rib structure.
Drawings
Fig. 1 is a schematic cross-sectional structure of the present invention;
fig. 2 is a schematic side view of the present invention.
Detailed Description
As shown in fig. 1 and 2, the utility model comprises a plurality of columns 2 supported on a concrete foundation 1, wherein the columns are transversely provided with a plurality of rows along a pedestal, a bearing beam 3 is arranged on the top of each row of columns 2, two ends of each bearing beam 3 are respectively provided with a reaction frame, the reaction frame comprises a vertical rod 4 with the lower end welded with the bearing beam, an inclined strut 5 is welded between the vertical rod 4 and the end part of the bearing beam, a supporting platform 6 is arranged at a certain height of the vertical rod 5 towards one side of the middle of the bearing beam, and a transverse jack 7 is arranged on the supporting platform 6; a plurality of sliding cushion blocks 8 are welded on the bearing beam 3 between the two reaction frames at equal intervals.
The utility model discloses during the concrete implementation, supporting platform 6 can adopt ordinary bracket structure, including the roof that a level set up, the curb plate of a vertical setting of roof one side welding, welding strength board between curb plate and roof, the curb plate is in with the montant welding of reaction frame or through bolt fixed connection, jack 7 transversely sets up on the roof.
The sliding cushion block 8 is used for supporting the arch rib and enabling the arch rib to move on the sliding cushion block so as to realize the adjustment of the position of the arch rib. In order to reduce the frictional resistance between the arch rib and the sliding cushion blocks, each sliding cushion block 8 is provided with a smooth arc-shaped top surface, and a layer of butter is coated on the arc-shaped top surface.
When the arch rib sections are assembled, the two arch rib sections 9 are hung between the two reaction frames on the pedestal by the crane, the arch rib sections are supported on the sliding cushion blocks 8 on the bearing beam, the jacks 7 on the reaction frames on the two sides of the arch rib push the arch rib sections to move left and right, the end parts of the two arch rib sections are aligned, and the labor intensity of workers can be reduced; after the arch rib sections are aligned, the jack 7 keeps a tight jacking state, welding between the two arch rib sections is carried out, the arch rib sections can be prevented from being displaced during welding, and welding precision is guaranteed.
