Abstract
The utility model relates to a construction platform for installation of steel trestle superstructure, including upper mounting plate and lower platform, upper mounting plate and lower platform are the rectangle frame construction, follow two vertical welding intervals in the rectangle frame and equal the longeron of trestle steel-pipe pile diameter, the longeron upper berth is equipped with the platform panel, upper mounting plate and lower platform are connected through the montant within a definite time, upper mounting plate and lower platform cover are established on two trestle steel-pipe piles, two brackets of horizontal symmetry welding along the trestle on the every trestle steel-pipe pile, two longerons of lower platform support on the bracket. The utility model discloses sound construction, the installation is stable, can provide safe and reliable's operation environment for the operation personnel on water.
Description
Technical Field
The utility model belongs to the technical field of aquatic bridge construction, when relating to aquatic steel trestle construction, be used for carrying out the construction platform of steel trestle superstructure installation.
Background
The construction of the bridge in water is usually carried out by erecting a steel trestle as a construction channel, and the steel trestle adopts a steel pipe pile as a lower supporting structure. After the steel pipe piles are inserted and driven, the upper structure of the trestle needs to be installed among the steel pipe piles, and the trestle comprises the parallel connection among the steel pipe piles and the welding of a bearing beam at the top of the steel pipe. The bucket of crawler crane is usually adopted as operation platform in the construction at present, and constructor carries out welding operation on water on the bucket, and the construction risk is big, and the security is low.
Disclosure of Invention
The utility model aims at the above-mentioned problem, provide a construction platform, support personnel's construction safety for steel landing stage superstructure installation.
The technical scheme of the utility model as follows:
the utility model provides a construction platform for steel trestle superstructure installation which characterized in that: the steel pipe pile lifting platform comprises an upper platform and a lower platform, wherein the upper platform and the lower platform are both rectangular frame structures, two longitudinal beams with the distance equal to the diameter of a trestle steel pipe pile are longitudinally welded in the rectangular frame, a platform panel is laid on the longitudinal beams, two steel pipe pile jacks are arranged on the platform panel between the two longitudinal beams according to the distance between the two trestle steel pipe piles, the upper platform and the lower platform are connected through a vertical rod, and guardrails are arranged on the peripheries of the upper platform and the lower platform; the upper platform and the lower platform are sleeved on the two trestle steel pipe piles, two brackets are welded on each trestle steel pipe pile along the trestle in a transverse symmetrical mode, and the two longitudinal beams of the lower platform are supported on the brackets.
The utility model discloses processing is accomplished on land, and through the track hoist and hang the cover on the steel-pipe pile, the platform passes through the bracket support on the steel-pipe pile, and two longerons centre gripping steel-pipe piles of platform, stable in structure is firm, can provide safe and reliable's operation environment for the operation personnel on water. Two-layer about the platform sets up, can carry out trestle steel-pipe pile parallel connection and upper portion spandrel girder installation respectively, can hang after a set of steel-pipe pile installation and continue construction on a set of steel-pipe pile next, but reuse.

FIG. 1 is a vertical view along the direction of the trestle of the present invention;
the input 2 is a schematic plane structure diagram of the utility model;
fig. 3 is a vertical view of the horizontal trestle of the present invention.
Detailed Description
As shown in fig. 1, 2 and 3, the utility model comprises an upper platform 1 and a lower platform 2, wherein the upper platform and the lower platform are both rectangular frame structures, two longitudinal beams 3 with the distance equal to the diameter of the trestle steel pipe pile are welded in the rectangular frame along the longitudinal direction, a platform panel 4 is laid on the longitudinal beams, two steel pipe pile jacks are arranged between the two longitudinal beams on the platform panel according to the distance between two adjacent trestle steel pipe piles, the upper platform and the lower platform are connected through a vertical rod 5, and guardrails 6 are arranged on the peripheries of the upper platform and the lower platform; the upper platform and the lower platform are sleeved on the two trestle steel pipe piles 7, two brackets 8 are welded on each trestle steel pipe pile 7 along the trestle in a transverse symmetrical mode, and the two longitudinal beams 3 of the lower platform 2 are supported on the brackets 8.
In order to facilitate the passage of constructors between the upper platform and the lower platform, the utility model discloses can set up cat ladder 9 between upper platform and lower platform during specific implementation.
The upper platform and the lower platform of the utility model are pre-processed on land, and the brackets are welded on the steel pipe pile in advance at a preset height before the steel pipe pile is inserted and beaten; after the trestle steel pipe piles are inserted and driven, the upper platform and the lower platform are sleeved on the two steel pipe piles by the crawler crane, constructors can weld the steel pipe pile parallel connection on the lower platform, and the steel pipe pile top bearing beam is welded on the upper platform. After welding, temporarily removing the part of the platform panel between the two longitudinal beams, and hoisting the platform to the next group of steel pipe piles by using a crawler crane to continue construction.
Claims (2)
1. The utility model provides a construction platform for steel trestle superstructure installation which characterized in that: the steel pipe pile lifting platform comprises an upper platform and a lower platform, wherein the upper platform and the lower platform are both rectangular frame structures, two longitudinal beams with the distance equal to the diameter of a trestle steel pipe pile are longitudinally welded in the rectangular frame, a platform panel is laid on the longitudinal beams, two steel pipe pile jacks are arranged on the platform panel between the two longitudinal beams according to the distance between the two trestle steel pipe piles, the upper platform and the lower platform are connected through a vertical rod, and guardrails are arranged on the peripheries of the upper platform and the lower platform; the upper platform and the lower platform are sleeved on the two trestle steel pipe piles, two brackets are welded on each trestle steel pipe pile along the trestle in a transverse symmetrical mode, and the two longitudinal beams of the lower platform are supported on the brackets.
