Description
Technical field
It the utility model is related to the construction of main rope of suspension bridge pretension, more particularly to a kind of structure for main rope of suspension bridge pretension
Part.
Background technology
In the construction of suspension bridge, main cable erection is most important, and the wherein tight cable construction of main push-towing rope is to ensure that main push-towing rope diameter reaches to set
Meter requires, main cable strand does not rouse silk, reaches the important step of force request, when tight cable is directly carried out using cable compacting machine, can cause
Main push-towing rope diameter does not meet phenomena such as design requirement, main push-towing rope drum silk, has a strong impact on main cable construction quality, is applied so that influenceing main cable erection
Work or even whole suspension bridge construction quality, schedule delays, cost increase.
The content of the invention
The shortcomings that the purpose of this utility model is to overcome prior art, there is provided one kind can guarantee that main cable construction quality and
Improve the component for main rope of suspension bridge pretension of efficiency of construction.
To solve prior art problem, technical solution adopted in the utility model is：
A kind of component for main rope of suspension bridge pretension, including the rectangular steel plates being made up of symmetrical two halves steel plate, two
Two semicircle orifices are symmetrically provided with half steel plate, described two semicircle orifices form horizontally disposed one of an axis
Circular hole, described circular hole are used for through main rope of suspension bridge, and two steel columns are vertically respectively welded at the outer of two halves steel plate
At wall, hole is had at the top of two steel columns, a screw rod passes through out of two steel columns perforate and passes through spiral shell
Bolt is fixedly linked with steel column, and bottom otic placode is welded with the bottom of each steel column, is provided with described bottom otic placode
Connecting hole, described connecting hole are used to connect chain block.
The utility model has advantages below：
1. component can ensure that main cable alignment is smooth, main push-towing rope does not rouse silk, ensure that applying for main push-towing rope before main push-towing rope formally tight cable
Working medium amount；
2. component can repeatedly, in circulation use, improve efficiency of construction, reduce construction cost；
3. component is gathered materials on the spot, preparation method is simple.
Brief description of the drawings
Fig. 1 is the structural representation of the component of main push-towing rope pretension cable of the present utility model；
Fig. 2 is the A-A sectional drawings of the structure shown in Fig. 1；
Fig. 3 is that the structure shown in Fig. 1 uses schematic diagram.
Embodiment
In order to further appreciate that invention, features and effects of the present utility model, following examples are hereby enumerated, and match somebody with somebody
It is as follows to close accompanying drawing detailed description：
Refering to Fig. 1~Fig. 3, a kind of component for main rope of suspension bridge pretension, including be made up of symmetrical two halves steel plate
Rectangular steel plates 1, are symmetrically provided with two semicircle orifices on two halves steel plate, and described two semicircle orifices form an axis along level
The circular hole that direction is set, described circular hole are used to vertically weld respectively through main rope of suspension bridge 6, two steel columns 2
It is connected at the outer wall of two halves steel plate, has hole at the top of two steel columns 2, a screw rod 5 is opened from two steel columns 2
Pass through in hole and be fixedly linked by bolt 4 with steel column, bottom otic placode 3 is welded with the bottom of each steel column 2,
Connecting hole is provided with described bottom otic placode 3, described connecting hole is used to connect chain block 7.
As shown in figure 3, during pretension cable, main rope of suspension bridge 6 is passed through into component circular hole, according to main push-towing rope actual conditions adjusting screw rod
5, chain block 7 is passed through to the connection hole of bottom otic placode 3, now screw rod is loose that two halves steel plate can be inside along screw rod
Slide, using manual adjustment chain block 7, you can carry out the pretension of main push-towing rope 6, steel disc can be used by rousing silk such as appearance during pretension cable
Combed and be aided with gavel and beaten, ensure pretension cable construction quality.
After the completion of pretension cable, fixed using stainless steel band at pretension cable.
Depending on device actual size of the present utility model is with job site actual conditions.
Main push-towing rope pretension cable component of the present utility model, it is that pretension cable is carried out to main push-towing rope before the tight cable of main push-towing rope in suspension bridge construction
A kind of component, structure manufacture is convenient, using simple, in practical application can repeatedly, recycle, both ensured that the tight cable of main push-towing rope was constructed
Quality, construction cost is reduced again, there is good practicality.
Above by reference to drawings and examples, component of the present utility model is schematically described, the description does not limit
Property processed.The construction technical staff of this area is understood that use, in actual applications, the making side of each part in the utility model
Some changes may occur for formula, and other staff may also make similar Design under its enlightenment.As long as it is pointed out that
Design aim of the present utility model, all obvious changes and its similar Design are not departed from, is all contained in the utility model
Protection domain within.
