It is linear to adopt the linear bridge state that is close to into of this structure main push -towing rope.
Description
Technical field
This utility model relates to laterally drawing device, particularly relates to Spatial Cable face structural cables system laterally to drawing device.
Background technology
Along with the development of suspension bridge construction technology, select in than process in the Longspan Bridge form such as valley, river of crossing over and more favor in earth anchored suspension bridge.Common rope-suspension bridge cable system adopts vertical curve linear, the inadaptable higher esthetic requirement that the outward appearance of Urban Bridge and scenic spot bridge is proposed.Spatial Cable face structural cables system configurations not only new in structure, and Spatial Cable face structural system also improves bridge self wind resisting stability energy, is selected by the famous Bridge Design in many places.Because main cable erection is in freely sagging horizontal alignment after completing in crossing over the Longspan Bridge Spatial Cable face such as valley, river structure construction procedure, make it to the linear a great problem transforming into work progress of bridge completion state at vacant state.According to past construction experiences select after the tight cable of main push-towing rope completes hoist engine, jack at span centre by freely sagging main push-towing rope laterally to drawing, but work progress is constantly in the process of groping, it does not have the construction method of a set of mature and reliable.
Summary of the invention
The purpose of this utility model is in that to overcome the shortcoming of prior art, a kind of simple in construction is provided, achieve multiple spot to apply laterally drawing active force, make main push-towing rope generation lateral shift, reaching the effect expected with multi-section-line replacement circular arc, main cable alignment is horizontal to drawing device close to the Spatial Cable face structural cables system that bridge completion state is linear.
This utility model be the technical scheme is that
nullA kind of Spatial Cable face of the present utility model structural cables system is laterally to drawing device,The multipair main push-towing rope that it includes being separately fixed on twice main push-towing rope is to pulling seat，Two main push-towing ropes that pulling seat is included being separately mounted on twice main push-towing rope along direction across bridge by every a pair main push-towing rope are to pulling seat，Pulling seat is included pedestal by each main push-towing rope respectively，Having along horizontally disposed rope hole of intermediate symmetry in the upper and lower of described pedestal，Every a pair main push-towing rope rope hole to pulling seat is equipped with steel wire bundle，At every a branch of steel wire bundle two ends, the outer wall place of pulling seat is connected to ground tackle by main push-towing rope，Steel wire bundle is fixed on main push-towing rope on pulling seat by ground tackle,Protrude respectively laterally in the middle of the outer wall of described pedestal and be provided with horizontal plate and lower horizontal board，On described upper horizontal plate and lower horizontal board, coaxial line has the pin joint hole vertically arranged，Described pin joint hole is for connecting cord clip otic placode on pulling seat and main push-towing rope pulling seat will be acted on main push-towing rope.
The beneficial effects of the utility model: tool structure is simple, need to use pin to be connected with cord clip otic placode, then install stretch-draw material and equipment for easy for installation.By this utility model patent, it is achieved that multiple spot applies laterally drawing active force, makes main push-towing rope generation lateral shift, reach the effect expected with multi-section-line replacement circular arc.Main cable alignment is linear close to bridge completion state, improves follow-up cord clip lateral deflection angle adjustment and hoist cable, stiff girder lifting construction progress, it is ensured that construction quality, reduce construction cost, decrease construction management difficulty, provides guarantee for standardized construction.

Fig. 2 is that the main push-towing rope in the device shown in Fig. 1 is to pulling seat schematic diagram.
Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, this utility model is described in detail.
Spatial Cable face of the present utility model as shown in drawings structural cables system is laterally to drawing device, the multipair main push-towing rope that it includes being separately fixed on twice main push-towing rope is to pulling seat 2, two main push-towing ropes that pulling seat 2 is included being separately mounted on twice main push-towing rope along direction across bridge by every a pair main push-towing rope are to pulling seat 2, pulling seat 2 is included pedestal by each main push-towing rope respectively, intermediate symmetry in the upper and lower of described pedestal have along horizontally disposed rope hole 2-1, every a pair main push-towing rope rope hole 2-1 to pulling seat 2 is equipped with steel wire bundle 1, at every a branch of steel wire bundle 1 two ends, the outer wall place of pulling seat 2 is connected to ground tackle 3 by main push-towing rope, steel wire bundle 1 is fixed on main push-towing rope on pulling seat 2 by ground tackle 3.Protrude respectively laterally in the middle of the outer wall of described pedestal and be provided with horizontal plate and lower horizontal board, on described upper horizontal plate and lower horizontal board, coaxial line has the pin joint hole 2-2 vertically arranged, described pin joint hole 2-2 is for connecting pulling seat 2 and cord clip otic placode on main push-towing rope, it is achieved will pulling seat be acted on main push-towing rope.
The installation and application of this device is as follows:
Pulling seat 2 is separately positioned on by main push-towing rope the 1/4 of main span, 1/2,3/4 place, and be provided with on the main push-towing rope to pulling seat place installation cord clip, utilizing cord clip as main push-towing rope, pulling force to be born a little.With the otic placode on main push-towing rope cord clip, main push-towing rope being carried out pin joint to pulling seat 2, is tentatively installed by cord clip and prevent being pulled through journey main cable strand appearance jumping silk situation, cat road is counter to be hung to main push-towing rope.Laterally adopt multiple tracks steel wire rope (steel wire rope number of share of stock is determined by biasing force) to form steel wire bundle 1 drawing device, use jack tension steel wire bundle 1 to make jack tension power transmit into main push-towing rope laterally to drawing active force, and fix steel wire bundle 1 with ground tackle 3.
