Description
Technical field
This utility model is related to a kind of buoyancy device of erecting steel truss girder on uplift pushing tow.
Background technology
With the fast development of Bridges in Our Country technology, the various type of bridges across rivers emerge in an endless stream, especially steel truss girder
With building height low, pattern is attractive in appearance, span is big etc., and advantage is widely used in railway, highway and urban track traffic.Mesh
Before, in the more city in coastal cities and inland river railway construction bridge, during overpass, large span letter often occurs
Prop up the situation that steel truss girder crosses over ship canal.Limited because the ship canal depth of water is not deep or by sluice gate, large-tonnage barge cannot
Enter waters operation and the iceound time is shorter, how to complete large-tonnage steel trusses floating and hauling construction becomes a great problem.
Content of the invention
For the above-mentioned problems in the prior art, this utility model provides one kind and is suitable to float bracket in ship canal
If the buoyancy device of steel truss girder, its Stability Analysis of Structures, using safe, economical and practical, ensure that leap ship canal steel truss girder floats
Bracket is provided as safety and the reliability of industry.
This utility model is achieved by the following technical solution: a kind of floating support of erecting steel truss girder on uplift pushing tow
Put, it is characterized in that: include combining, by some buoyancy tanks, the buoyancy aid being formed, described buoyancy aid is fixed with two groups of bottom distribution beam, every group
Bottom distribution beam top is fixedly installed a bracing frame being made up of steel pipe, and each support frame as described above top is fixedly installed one group
Top distribution beam, the top pushing up distribution beam described in every group is fixedly installed a support pier.
In order to improve bearing capacity and the stability of bracing frame, further, support frame as described above includes four rectangular cloth
The supporting steel pipe being vertically arranged put, is connected by joint steel pipe between described supporting steel pipe, in the outside of described supporting steel pipe
It is fixedly connected with the many reinforcement steel pipes arranging obliquely, the upper end strengthening steel pipe is connected with supporting steel pipe, strengthen steel pipe and prop up
Form triangular structure of right angle between support steel pipe, strengthen between steel pipe and strengthen between steel pipe and supporting steel pipe all by being connected steel
Pipe connects.Preferably, the overall structure that support frame as described above is formed for steel-pipe welding.
In order to improve using safety and reliability, two support frames as described above are symmetrical arranged in the distribution beam of bottom.It is symmetrical arranged
Two bracing frames the power that two groups of top distribution beam hand down uniformly can be delivered on buoyancy aid it is ensured that construction safety.
In view of the safety and reliability constructed it is preferable that described bottom distribution beam is assemblied to form by I-steel.
In this utility model, buoyancy aid is formed by connecting using buoyancy tank, buoyancy tank can via land transport to canal harbour or
Bank carries out assembly, and buoyancy tank is highly little, can not sail the waters not deep with the depth of water in barge container and carry out construction operation,
Which solve barge container can not sail into the ship canal not deep with waters cannot float bracket set Longspan Bridge construction difficult
Topic.This utility model Stability Analysis of Structures, safe and reliable, and it is short to process installation period, economical and practical, can be effectively ensured big across
Degree freely-supported steel truss girder floats safety and the reliability of support erection construction.

Specific embodiment
Below by embodiment and combine accompanying drawing to this utility model further instruction:
As shown in drawings, a kind of buoyancy device of erecting steel truss girder on uplift pushing tow, it is included by some buoyancy tanks according to one
The buoyancy aid 1 that mould-fixed combination is formed, described buoyancy aid 1 is fixed with two groups of bottom distribution beam 2, described bottom distribution beam 2 is by I-steel
It is assemblied to form.Every group of bottom distribution beam 2 top is fixedly installed a bracing frame being made up of steel pipe 3, on each support frame as described above 3
Portion is fixedly installed one group of top distribution beam 4, and the top pushing up distribution beam 4 described in every group is fixedly installed a support pier 5.Preferably, two
Individual bracing frame 3 is symmetrical arranged in bottom distribution beam 2.
Support frame as described above 3 includes four supporting steel pipes 31, and four supporting steel pipes 31 are in rectangular layout and are vertically arranged, four
Connected by joint steel pipe 32 between supporting steel pipe 31.It is fixedly connected with many in the outside of described supporting steel pipe 31 oblique to divide into
The reinforcement steel pipe 33 put, the upper end strengthening steel pipe 33 is fixed together with supporting steel pipe 31, strengthens steel pipe 33 and supporting steel
Form triangular structure of right angle between pipe 31.Strengthen between steel pipe 33 and strengthen between steel pipe 33 and supporting steel pipe 31 all by even
Connect steel pipe 32 to connect.Preferably, the overall structure that bracing frame 3 is formed for steel-pipe welding.
Other parts in the present embodiment adopt known technology, will not be described here.
This utility model Stability Analysis of Structures, safe and reliable, and structure is simple, and it is easy to process, processing installation period is short, its
Solve and can not sail the ship canal not deep with waters in barge container and cannot float the technical barrier that bracket sets Longspan Bridge,
Ensure that crossing over ship canal steel truss girder floats safety and the reliability that bracket is provided as industry, economic and practical is strong.
