Abstract

The utility model discloses a wire rope hanging bracket platform for reinforcement of arch bridges, wherein the wire rope hanging bracket platform is low in construction investment and cost and facilitates rapid and standardized construction. The wire rope hanging bracket platform is composed of a hanging ring, a turn buckle, wire ropes, rope clips, a hawser cable, transverse rods, longitudinal rods, transverse tie rods, guardrails, handles, bamboo scaffold board baffles, bamboo scaffold board floor boards, safety nets and the like. The hanging ring is arranged through an original main arch ring in a rebar planting anchorage mode; one end of the turn buckle is hung to the hanging ring, and the other end of the turn buckle is connected with the wire rope; the wire rope is anchored to and hangs the transverse rods through the rope clips; the longitudinal rods are arranged on the transverse rods at certain intervals; the dense transverse tie rods are arranged between the adjacent transverse rods; the bamboo scaffold board floor boards are transversely laid on the longitudinal rods; the edge protective guardrails are vertically arranged on the transverse rods; the handles are hung between the two longitudinal rods through the wire ropes; the bamboo scaffold board baffles are arranged on the inner sides of the guardrails; the safety nets are hung on the two sides respectively. The wire rope hanging bracket platform is suitable for building of under-arch platforms for reinforcement of all large-span deck type concrete arch bridges.

Description

Cable hanger platform for Arch Bridges Strengthening

Technical field

The utility model relates to a kind of cable hanger platform for Arch Bridges Strengthening and sets up process.

Background technology

At present, be directed to operation platform under the arch of reinforcing across footpath deck type concrete arch-type bridge main arch ring greatly, mainly take floor stand formula, movable hanging basket formula.Floor stand formula, is divided into full hall formula floor stand and steel pipe floor stand.Shortcoming: will have suitable supporting capacity requirement to ground or basis, highly increase along with arch is lower, support consumption increases, long construction period, construction cost is high.For crossing over river regime, exist and be subject to Flood impact safety risk hidden danger; For crossing over coulee situation, transporting bracket cost is high, rehandling difficulty.Movable hanging basket formula, by bridge floor counterweight walking dolly, elongated Hanging Basket under mounting arch.Shortcoming: along with the height change of spandrel construction, need to adjust the lower cradle construction height and position of arch, and take part bridge deck width.In addition, Hanging Basket self operating space is limited, causes the lower construction working face of arch fully to carry out restricted, long construction period, and construction cost is high.

Summary of the invention

Main purpose of the present utility model is to provide a kind of cable hanger operation platform for Arch Bridges Strengthening, to eliminate the above-mentioned shortcoming of current employing technology.

The utility model has the advantages that, can utilize former main arch ring that lower suspension centre is set, adopt conventional fastener type scaffold tubes to set up suspension bracket, support consumption is few, and the cycle of setting up is short, be not subject to underbridge clearance and environmental influence, it is less that construction period is affected by Flood water level, can meet porous full of setting up, guaranteed fully carrying out of porous construction working face, construction input and cost are low, safe and reliable, are convenient to standardized construction.

Concrete technical scheme of the present utility model, the lower cable hanger platform of arch is mainly comprised of suspension ring, flower basket bolt, wire rope, wire clips, cable wind rope, cross bar, vertical pole, lateral ties bar, railing, handrail, bamboo scaffold floor baffle plate, bamboo scaffold floor bed board and safety net etc.Wherein descend suspension centre by suspension ring shape is processed into in reinforcing bar one end, one end is implanted main arch ring structure and is carried out anchoring.Flower basket bolt two ends adopt CO type, and one end hangs on suspension ring, and one end, by wire clips connecting steel wire ropes, act as the tightness of steel wire rope degree that regulates.Cross bar, vertical pole, lateral ties bar, railing all adopt conventional fastener type scaffold tubes.Wire rope hangs cross bar by wire clips anchoring, and cross bar adopts the single spreading of clasp, and adopt two of rotary buckles side by side overlapping mode with whole load-bearing, adopt 2 scaffold tubes to overlap side by side, and rotary buckle is set is across a certain distance fastened into integral body mutually.On cross bar, mutually set up across a certain distance vertical pole, and between adjacent crossbars, arrange and encrypt lateral ties bar, between cross bar or lateral ties bar and vertical pole, all adopt right-angle coupler to be connected, bamboo scaffold floor bed board is laterally laid on vertical pole.Face bound defence rail and vertically set up on cross bar, handrail adopts wire rope to be hung between two vertical railings, and railing inner side arranges bamboo scaffold floor baffle plate, and both sides respectively hang close order safety net.In addition, by being set, cable wind rope strengthens the wind resisting stability of whole suspension bracket.
