Description
Technical field
The utility model relates to a kind of expansion joint section bar positioning devices of high-speed railway bridge.
Background technology
With the rapid development of China express railway construction, high speed railway construction scale and quantity are increasing, bridge knot
Structure with its structure durability it is strong, long lifespan, take up an area the advantages such as smaller, great proportion is occupied in high-speed railway structure.Bridge
Beam telescopic device is the important component in bridge superstructure, passes through bridge floor tie-beam and beam（Or abutment）.Flexible gap is set
It is set to and corrodes and be stained beam for Deck Water Leakage（Pier）Body, bearing, the most important approach for checking facility and pier.Expansion gap device
Setting requirements in both directions parallel, perpendicular to bridge axes, can freely stretch, solid and reliable, train driving is out-of-date
It should smooth out, without kick and noise；It can prevent rainwater and rubbish soil from penetrating into obstruction；Installation checks, maintenance, eliminates dirt all
Want simple and convenient.At setting expansion joint, deck paving will disconnect.
For present high-speed railway bridge using a kind of quick-replaceable rubber strip expansion joint, critical piece is aluminium alloy abnormal shape
Material.After the completion of fish tail and waterproof layer construction is treated during construction, expansion joint installation can be carried out.In the installation process of expansion joint, account for
It is exactly the installation and positioning of aluminium alloy extrusions with construction time longest process.Because expansion joint setting requires its installation horizontal, it is
Ensure expansion joint aluminium alloy deformed bar installation horizontal accuracy, need during traditional construction artificial direction across bridge multiple spot high using square positioning
Profile shapes is risen into location and installation using tools such as crowbars after degree.It is constructed by the method, finds to deposit using traditional positioning method
In following shortcoming：（1）Because that square need to be used to position, easily there is mistake in worker's metrology operation；（2）It is lifted using this mode
Section bar construction accuracy is not easy to grasp, and deviation easily occurs in horizontal elevation；（3）This mode construction efficiency is relatively low, causes artificial timely
Between waste.
Invention content
The purpose of this utility model aiming at the deficiency present in the prior art, and provides a kind of expansion joint section bar and determines
Expansion joint can be completed using the bridge floor protective layer for pouring completion without manually measuring rising height point by point in position device, the device
The horizontal elevation positioning of section bar, saves time and manpower, and horizontal elevation accurate positioning, ensure that matter is installed at expansion joint
Amount.
This programme is achieved by the following technical measures：A kind of expansion joint section bar positioning device, including supporting mechanism
With section bar suspension gear, the supporting mechanism includes two cross bars, two longitudinal rods is fixed between two cross bars；The type
Material suspension gear includes the vertical bar being fixed on supporting mechanism, and supporting rod is set in vertical bar, is provided with and hangs on supporting rod
Chain, the front end of chain sling are provided with the hook for lifting section bar.The guide pipe for passing through chain sling is provided on supporting rod.It leads
It is flexibly connected to pipe with supporting rod.
The vertical bar is two, and supporting rod is fixed between two vertical bars, and vertical bar is fixed on two longitudinal rods
Between cross bar on.Filler strip is provided with below longitudinal rod.
The advantageous effect of this programme can be learnt according to the narration of said program, due to having cross bar and longitudinal direction in this scenario
Bar can play the role of to whole device support it is fixed, be convenient for lifting；Vertical bar can support chain sling, be hung convenient for hook
Section bar is filled, has guide pipe can be to pass through chain sling, and guide pipe is flexibly connected with supporting rod, guide pipe can rotate, can basis
Need of work adjusts the direction of guide pipe, is easily installed section bar；Supporting rod is fixed between two vertical bars, can be caused in this way
Whole device is more secured, avoids moving when using；Filler strip is set below longitudinal rod, due to stretching in installation rubber strip
During seam, need that placement steel plate is needed to prevent its structure from destroying on the section bar of expansion joint, have the presence of filler strip that can just make to stretch in this way
The hoisting height of seam section bar reaches the position specified, otherwise will be relatively low.It can be seen that the utility model and prior art phase
Than there is substantive distinguishing features and progress, the advantageous effect implemented is also obvious.
Description of the drawings
Fig. 1 is the structure diagram of specific embodiment of the present invention.
Fig. 2 is the structure diagram of longitudinal rod.
In figure, 1 is cross bar, and 2 be longitudinal rod, and 3 be vertical bar, and 4 be hook, and 5 be chain sling, and 6 be supporting rod, and 7 be guide pipe,
8 be filler strip.
Specific embodiment
In order to clarify the technical characteristics of the invention, below by a specific embodiment, and its attached drawing is combined, it is right
This programme is illustrated.
By attached drawing as can be seen that the expansion joint section bar positioning device of this programme, suspends machine in midair including supporting mechanism and section bar
Structure, the supporting mechanism include two cross bars 1, two longitudinal rods 2 are fixed between two cross bars 1；The section bar suspends machine in midair
Structure includes the vertical bar 3 being fixed on supporting mechanism, and supporting rod 6 is set in vertical bar 3, chain sling 5 is provided on supporting rod 6,
The front end of chain sling 5 is provided with the hook 4 for lifting section bar.The guide pipe 7 for passing through chain sling 5 is provided on supporting rod 6.
Vertical bar 3 is two, and supporting rod 6 is fixed between two vertical bars 3, and vertical bar 3 is fixed on the cross bar between two longitudinal rods 2
On 1.The lower section of longitudinal rod 2 is provided with filler strip 8.
When constructing at expansion joint, the present apparatus is placed on beam seam both sides and has been poured on the protective layer of completion, adjusting apparatus is extremely
Suitable position keeps chain sling 5 vertical with the section bar that need to be promoted；Aluminium alloy extrusions is tangled with the hook 4 of section bar suspension gear and is hung
It rises to device bottom surface, then welds vertical spacer bar, ensure the stabilization of section bar；Using expansion joint fast-positioning device without people
Work measures rising height point by point, and the horizontal elevation that expansion joint section bar can be completed using the bridge floor protective layer for pouring completion is positioned,
Time and manpower, and horizontal elevation accurate positioning are saved, ensure that expansion joint installation quality.
