Abstract
The utility model provides a kind of steel box-girder installation bracket equipped with safe operation platform, the operating platform that connection one extends horizontally outward in the end of two I-shaped goosenecks of cradle top, platform side and two I-steel beam-ends are welded, the construction personnel passway of rectangle is equipped among platform, ladder is equipped between the lateral bar and operating platform bottom of the top between outermost two steel columns of bracket direction across bridge, it is welded among the lower end of ladder and lateral bar, the construction personnel passway on upper end and operating platform is welded far from the side of steel column.The utility model problem narrow for operating space at the top of existing steel box-girder installation falsework, sets up operating platform at bracket both ends, under the premise of not influencing steel box-girder installation, provides the operating space of safety spaciousness for construction personnel.
Description
Technical field
The utility model relates to steel box girder bridge technical field of construction, and in particular to a kind of facing for steel box-girder installation
When bracket.
Background technique
Steel box girder bridge has many advantages, such as that big span, short construction period and working procedure are simple, is widely used in across existing
The science of bridge building of road.When steel box-girder installation, need to set up multiple falseworks, each falsework below steel box-girder
Including direction across bridge two rows of steel columns disposed in parallel, every steel column lower end is supported in ground base, every row's steel column it is upper
End is connected by I-shaped gooseneck, is connected by diagonal brace with lateral between adjacent steel column.
When steel box-girder installation, sand cylinder or jack to be installed in cradle top, be used for temporary support steel box-girder, and right
Steel box-girder absolute altitude is adjusted and controls；After steel box-girder is adjusted in place, sand cylinder or very heavy heights of roofs are reduced, steel box-girder is fallen on into bridge
On pier support.It needs to be operated at the top of falsework by construction personnel in work progress.But falsework headspace is narrow
It is narrow, operating space and walking passageway of the plank as construction personnel can only be set up between the horizontal-associate bar between two rows of steel columns, no
Only construction is inconvenient, and since most of constructing operations are positioned at the progress of bracket both ends, face do-nothing operation and be highly detrimental to ensure
The safety of construction personnel.
Summary of the invention
The purpose of this utility model is that can not ensure construction personnel's safety operation for existing steel box-girder mounting bracket
Problem provides a kind of steel box-girder installation bracket equipped with safe operation platform, facilitates construction, and ensure the peace of construction personnel
Entirely.
The technical solution of the utility model is as follows:
A kind of steel box-girder installation bracket equipped with safe operation platform, the bracket includes that direction across bridge is disposed in parallel
The lower end of two rows of steel columns, every steel column is supported in ground base, is connected between adjacent steel column by diagonal brace and lateral
It connects, the upper end of every row's steel column is connected by I-shaped gooseneck, it is characterised in that: the connection one in the end of two I-shaped goosenecks
The operating platform extended horizontally outward along I-shaped gooseneck, the side of the operating platform and I-steel beam-end are welded, behaviour
Make the construction personnel passway that rectangle is equipped among platform, the lateral of the top between outermost two steel columns of direction across bridge
Be equipped with ladder between bar and operating platform bottom, welded among the lower end of the ladder and the lateral bar, the upper end of ladder and
It is welded far from the side of steel column construction personnel passway on operating platform.
The utility model attended operation platform on existing steel box-girder installation falsework, and operating platform is in bracket
Both ends extend outwardly, and under the premise of not influencing to install steel box-girder on bracket, have expanded cradle top space significantly, can be to construction
Personnel provide the spacious operating environment of safety, facilitate construction personnel in steel column and I-steel cross rail top setting sand cylinder or
Jack, and the adjustment control steel box-girder absolute altitude in steel box-girder installation, are able to satisfy construction requirement, and can sufficiently ensure constructor
Member's safety.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model direction across bridge；
Fig. 2 be the utility model along bridge to structural schematic diagram；
Fig. 3 is the planar structure schematic diagram of operating platform frame.
Specific embodiment
As shown in Figure 1 and Figure 2, the utility model bracket includes direction across bridge two rows of steel columns 1 disposed in parallel.Every row's steel is vertical
Column has more, two for being located at bracket one end in row's steel column is merely illustrated in Fig. 1, the structure of the bracket other end is identical.Often
The lower end of root steel column 1 is supported in ground base 2, face between two adjacent steel columns 1 and between two rows in every row
It between two steel columns, is all connected by diagonal brace 3 and lateral 4, the upper end of every row's steel column is connected by I-shaped gooseneck 5, two
The operating platform 6 that the end connection one of root I-shaped gooseneck 5 extends horizontally outward along I-shaped gooseneck 5, the operating platform 6
Side and 5 end of I-shaped gooseneck are welded；The construction personnel passway of rectangle is equipped among the operating platform 6, in direction across bridge
Ladder 7 is equipped between outermost two steel columns 1 between the lateral 4 and operating platform bottom of the top, under the ladder 7
It holds and is welded among the lateral 4, side of the construction personnel passway far from steel column on the upper end and operating platform of ladder 7
Welding.
In above structure, on the other hand channel of 7 one side of ladder as construction personnel's down operation platform 1 is made
For the support of platform, stabilization is played to platform, and platform and bracket is made to connect into a firm entirety.Construction personnel Ke Tong
It crosses round-trip on the channel that ladder is set up between platform and bracket lateral and carries out corresponding constructing operation.
As shown in figure 3, the operating platform 6 include it is horizontally disposed by more horizontally disposed cross bars 61 and Duo Gen and with cross
The rectangular platform frame that the vertical vertical pole 62 of bar is welded into is laid with flat surface plate on the platform framework.After being laid with platform panel,
The top surface of platform panel will be flushed with the top surface of I-shaped gooseneck 5.
When the cross bar 61 of platform framework is connect with vertical pole 62, construction personnel passway 63 is reserved among platform framework,
When being laid with platform panel, corresponding passway is also set with the corresponding position in construction personnel passway on platform framework.
Further, the utility model in the specific implementation, can be in side of the operating platform 6 far from steel column and and I-steel
The parallel two sides of crossbeam 5, are respectively set platform guardrail 8, form a semi open model operating platform, can both construction personnel be protected to pacify
Entirely, and facilitate construction personnel in steel column and I-steel cross rail top setting sand cylinder or jack, and adjustment control steel box-girder
The operation such as absolute altitude.
