Abstract
The utility model discloses a trestle assembling platform which is located on a padded riverbed below a large-scale trestle. The trestle assembling platform is rectangular and comprises landing legs, a platform frame beam and a face plate, a group of the landing legs is respectively arranged on the platform along directions of two short edges, at least three groups of the landing legs are arranged on the platform along directions of two long edges at intervals, a ground beam is connected with the lower portion of each group of the landing legs and parallel to the short edges, the length of the ground beam is larger than that of the short edges of the platform, the space between two adjacent landing legs is larger than the width of a headrace channel on the surface of the riverbed, a baseboard is respectively arranged below the bottom surface of the ground beam and a corresponding landing leg, the area of the baseboard is larger than that of the section of the corresponding landing leg, a cross bracing is arranged between two adjacent ground beams, and a diagonal bracing is arranged between two adjacent landing legs. According to the trestle assembling platform, the technical problem that the trestle is difficult to assemble when construction sites of river trestles are small and space for assembling the trestle is insufficient is solved.
Description
Technical field
The utility model relates to a kind of assistance platform of making building unit, particularly a kind of platform that is used for the assembly unit steel trestle.
Background technology
When steel trestle was constructed, every section trestle all needed assembly unit at the scene to complete.General structure manufacture place is broad relatively, and traditional way is promptly in the assembly unit of enterprising broker's storehouse, the vacant lot bridge on a construction limit.Narrow and small when the job site, particularly when the job site of cross a river trestle assembly unit trestle insufficient space, be badly in need of the platform for lining that a kind of limited execution conditions capable of using directly use.
The utility model content
The purpose of the utility model provides a kind of trestle platform for lining, and solution cross a river trestle job site is narrow and small, during assembly unit trestle insufficient space, and trestle assembly unit difficult technologies problem.
For realizing above-mentioned purpose, the utility model adopts following technical scheme:
A kind of trestle platform for lining is positioned on the riverbed that pads below the large-scale trestle, and it is shaped as rectangle; It comprises supporting leg, table top Vierendeel girder and panel; Said platform respectively has one group of supporting leg at two short side directions, at two long side directions of said platform at least three group supporting legs is set at interval, is connected with elongated grade beam below every group of supporting leg; Said grade beam is parallel with minor face; And length is greater than the bond length of platform, and the spacing of two adjacent supporting legs is greater than the width of riverbed surface disposal ditches, also is connected with the base plate of its area greater than the supporting leg cross section below in the bottom surface of grade beam, corresponding to each supporting leg; Be connected with stull between said grade beam and the adjacent grade beam, be connected with diagonal brace between said supporting leg and the adjacent legs.
The web both sides of said grade beam can be welded with stiffened panel corresponding to the position below the supporting leg.
Said base plate can be steel plate or plank.
Said grade beam can be i iron or H shaped steel.
Said stull can be channel-section steel, angle steel or i iron.
Said supporting leg can be i iron or H shaped steel.
Said table top Vierendeel girder can be i iron, channel-section steel or H shaped steel.
Said diagonal brace can be round steel pipe or square steel pipe.
Compared with prior art the utlity model has following characteristics and beneficial effect:
It is narrow and small that the utility model has overcome cross a river trestle job site, during assembly unit trestle insufficient space, and trestle assembly unit difficult technologies problem, limited execution conditions capable of using are built on the riverbed.
The utility model main body is a steel work, builds and removes conveniently, has broad applicability, and safe.
Description of drawings
Below in conjunction with accompanying drawing the utility model is done further detailed explanation.
Fig. 1 is the structural representation of the utility model.
Reference numeral: 1-grade beam, 2-stull, 3-supporting leg, 4-diagonal brace, 5-table top Vierendeel girder, 6-stiffened panel, 7-panel, 8-base plate, 9-riverbed, 10-disposal ditches.
The specific embodiment
Embodiment is referring to shown in Figure 1, and a kind of trestle platform for lining is positioned on the riverbed 9 that pads below the large-scale trestle; It is shaped as rectangle, and it comprises supporting leg 3, table top Vierendeel girder 5 and panel 7, and said platform respectively has one group of supporting leg 3 at two short side directions; Two long side directions at said platform are provided with at least three group supporting legs at interval; Be connected with elongated grade beam 1 below every group of supporting leg, said grade beam 1 is parallel with minor face, and length is greater than the bond length of platform; The spacing of two adjacent supporting legs is greater than the width of riverbed surface disposal ditches 10; Also be connected with the base plate 8 of its area below in the bottom surface of grade beam 1, corresponding to each supporting leg 3, be connected with stull 2 between said grade beam 1 and the adjacent grade beam, be connected with diagonal brace 4 between said supporting leg 3 and the adjacent legs greater than the supporting leg cross section.
The web both sides of said grade beam 1 also are being welded with stiffened panel 6 corresponding to the position below the supporting leg 3.
In the present embodiment, desirable base plate 8 is a steel plate, and specification is 20X500X500, and grade beam 1 is the hot rolled H-shaped of HN400X200.Stull 2 is No. 10 channel-section steels.Supporting leg 3 is an i iron.Table top Vierendeel girder 5 is the H shaped steel of HW200X200.Diagonal brace 4 is the round steel pipe of diameter 80mm.
The method for using of the utility model: before the assembly unit trestle, pad the riverbed is smooth earlier, set up the trestle platform for lining; For guaranteeing the safety of platform; All channel-section steels preferably use more than No. 10, and grade beam 1 is placed on the node location of trestle, receive the influence of the field condition and the lifting appliance radius of gyration; The trestle platform for lining should shift to an earlier date unwrapping wire location, in order to avoid the trestle assembly unit exceeds the radius of gyration of mobile crane after good.After the trestle assembly unit is accomplished, remove platform for lining.
