Abstract
The utility model relates to a walking beam bottom working platform for strengthening a cable-stayed bridge concrete box beam. The working platform comprises a working platform body which comprises a plurality of hanger frames which are arranged on two sides of the working platform body in parallel and a bottom basket support, the hanger frames comprise vertical supports and bearing beams, and bottom ends of the hanger frames are connected with two ends of the bottom basket support; and walking systems are arranged on the inner sides on the upper portions of the hanger frames. The walking beam bottom working platform has the advantages that by aid of a novel structure design, in prior bridge strengthening construction, a prior bridge can be used, sufficient operation space is provided for beam bottom strengthening operation by arranging the walking beam bottom working platform, the platform can move horizontally along the walking direction of the bridge and can cross bridge floor stay cables and hanger rods to reach a next operation plane successfully, a scaffold is not needed to be erected or a bridge inspection van is not needed to be used in water or valleys, and the working platform is safe and efficient and economical and practical.
Description
Technical field
The utility model relates to a kind of cable stayed bridge concrete case beam reinforcing and makes platform with walking beam basic skill or training.
Background technology
Along with different types of rridges more and more appear in the middle of the productive life, the demand that bridge maintenance is reinforced also increases day by day, and the conditionally complete of the maintenance strengthening construction condition of existing bridge when newly-built is different.Reinforcing operation all constructs below the beam face, especially for the water Bridge or cross over the high-altitude bridge of cheuch, adopt conventional full framing or bridge detection vehicle operation, efficient is low, and cost is high, especially reinforces in the job execution at the bottom of the suspension cable beam, platform movement need stride across suspension cable, suspension rod, tear rope open, change rope, the links such as affixing steel plate, affixing carbon fabric, crack, defect mending, not only complex steps, and security performance and the actual effect of using are all had a greatly reduced quality.Therefore provide a kind of novel bridge maintenance strengthening construction platform, thereby overcome the above problems, imperative.
The utility model content
The purpose of this utility model is to provide a kind of cable stayed bridge concrete case beam to reinforce and makes platform with walking beam basic skill or training, on the basis of the basic function that satisfies existing bridge maintenance reinforcement platform, and security performance and the result of use of further Perfect the work platform.
The purpose of this utility model is to be achieved through the following technical solutions:
A kind of cable stayed bridge concrete case beam is reinforced and is made platform with walking beam basic skill or training, comprise the working platform body, described working platform body comprises the some suspension brackets that be arranged in parallel in both sides and end basket support, and described suspension bracket comprises vertical support frame and spandrel girder, and described suspension bracket bottom is connected with basket support two ends, the end; Described suspension bracket upper inner is provided with running gear.
Further, be equipped with raker beam between described vertical support frame and the spandrel girder and between described suspension bracket and the end basket support.
The beneficial effects of the utility model are: by the structure design of innovation, so that in existing Bridge repair and reinforcement construction, can utilize existing bridge, by being arranged in walking working platform at the bottom of the beam, provide enough working spaces for reinforcing operation at the bottom of the beam, platform can move horizontally along the bridge direction of traffic, can stride across bridge floor suspension cable and suspension rod, arrive smoothly the next scope of operation, and not need to set up in water or in the mountain valley scaffold or use bridge inspection vehicle, safe and efficient, economic and practical.
Description of drawings
The below is described in further detail the utility model with reference to the accompanying drawings.
Fig. 1 is that the described a kind of cable stayed bridge concrete case beam of the utility model embodiment is reinforced the structural representation of making platform with walking beam basic skill or training.
Among the figure:
1, suspension bracket; 2, running gear; 3, end basket support; 4, raker beam.
The specific embodiment
As shown in Figure 1, the described a kind of cable stayed bridge concrete case beam of the utility model embodiment is reinforced and is made platform with walking beam basic skill or training, comprise the working platform body, described working platform body comprises the some suspension brackets that be arranged in parallel 1 in both sides and end basket support 3, described suspension bracket 1 comprises vertical support frame and spandrel girder, and described suspension bracket 1 bottom is connected with basket support 3 two ends, the end; Described suspension bracket 1 upper inner is provided with running gear 2.Between described vertical support frame and the spandrel girder, and be provided with raker beam 4 between described suspension bracket 1 and the end basket support 3.
During concrete the use, form agent structure by suspension bracket 1, end basket support 3 and running gear 2, but running gear 2 can be arranged to the combination of walking dolly and track or the combination of other flexible motion; The every side in working platform upstream and downstream forms the suspension centre system by five suspension brackets, when the hanging basket reach needs to cross over suspension rod or suspension cable, removes suspension bracket spandrel girder, raker beam, after the load-bearing girder span is got over suspension rod, this spandrel girder, raker beam is installed again.Successively by suspension rod or suspension cable, whole hanging basket can arrive next operating area by suspension cable to other suspension bracket spandrel girder smoothly by that analogy.After the hanging basket walking put in place, bridge floor upstream and downstream suspension bracket spandrel girder carried out improving the hanging basket safety to drawing with wire rope.Basket leaves enough spaces apart from case beam base plate at the bottom of the hanging basket, for the operation of different types of rridges maintenance and reinforcement.
Working platform installation and the course of work during use are as follows:
1) at the bottom of bridge, hanging basket is assembled in placely, with crane hanging basket is winched to bridge floor, installation in position;
When 2) walking, run into suspension cable, open foremost suspension bracket spandrel girder and diagonal brace, utilize trailer system (hoist engine or Chain block) pulling hanging basket at the uniform velocity to move ahead in orbit.
3) after spandrel girder passes through suspension cable, install this spandrel girder and diagonal brace, open next root spandrel girder and diagonal brace, the rest may be inferred, until whole hanging basket passes through suspension cable.
4) after hanging basket walking puts in place, with smart prick screw-thread steel with hanging basket at the bottom of basket and case beam base plate hang and connect the safety of raising hanging basket.
5) after the hanging basket walking put in place, bridge floor upstream and downstream suspension bracket spandrel girder carried out improving the hanging basket safety to drawing with wire rope.
The utility model is not limited to above-mentioned preferred forms; anyone can draw other various forms of products under enlightenment of the present utility model; no matter but do any variation in its shape or structure; every have identical with a application or akin technical scheme, all drops within the protection domain of the present utility model.
