Description

Lower support type Hanging Basket in the bridge construction
Technical field
The utility model relates to the cradle structure in a kind of bridge construction.
Background technology
In bridge construction, Hanging Basket is to be used to have current the requirement and the relatively poor cast-in-place a kind of device of large-span concrete bridge cantilever of foundation condition.
Cradle structure commonly used at present comprises deck type triangle hanging basket, Diamond-Shape Form Traveler, bowstring type Hanging Basket and hybrid Hanging Basket or the like, and the Hanging Basket of these existing forms all is arranged on the top of beam body.The concreting state of various Hanging Baskets is similar with the suffered force mode of Hanging Basket walking states, be to guarantee stability in the cradle construction process, and is must pre-buried fining twisted steel on casting beams body heavy as back anchor or load balance.When hanging blue traveling anti-bearing, glide path and the glide path anchor bar of drawing must be set, wherein, the anti-bearing that draws passes to the beam body of having built by glide path and glide path anchor bar with pulling force, and the glide path anchor bar is clouded on the slideway of all box girder segments.Bottom die platform and external mold are hung traveling on the sliding outside beam, and the length of sliding beam must be built sections above two outward.Mainly there is following problem in this traditional deck type Hanging Basket in construction:
Need the fining twisted steel of pre-buried a greater number when 1, constructing, these built-in fittings are embedded in the case beam and can't reclaim, and cause waste of material;
2, the pre-buried required precision of glide path anchor bar is higher, and the utilization rate again of slideway is extremely low;
3, anti-setting of drawing bearing is comparatively complicated, uneconomical;
4, the space at beam body top is subjected to the restriction of deck type main truss cradle shelf structure, make beam body cage of reinforcement can only be according to the conventional method on bottom die platform the scene advance colligation, operation easier is big, influences the duration;
5, the deck type Hanging Basket moves slowly, must draw bearing to cooperate repeatedly to finish by counter in the process out of shape, time-consumingly takes a lot of work again;
The utility model content
The utility model is for avoiding above-mentioned existing in prior technology weak point, provide a kind of can improve Hanging Basket mode out of shape, and can will finish the cage of reinforcement integral body of colligation hang in and directly carry out the concreting operation in the bottom die platform space, with the lower support type Hanging Basket in the bridge construction of reduction of erection time.
The utility model technical solution problem adopts following technical scheme:
The design feature of the lower support type Hanging Basket in the utility model bridge construction is:
Have two and fall trapezoidal main couple, by upper chord, lower chord, be connected between upper chord and the lower chord montant to and brace constitute; At the afterbody of described upper chord and between the bottom surface of casting beams section box beam flange plate upper chord is set and shores jack, and a pair of bottom surface with the described section of casting beams box beam flange plate is set is the road wheel of supporting surface; Between the middle part of described upper chord and back top rail, the back upper hanger is set; The front end of described upper chord is connected with preceding top rail; Between the middle part of described lower chord and back lower transverse beam, suspension rod under the back is set; Before described between top rail and the preceding lower transverse beam before suspension rod be connected;
At described back top rail and between the end face of casting beams section cushion block has been set;
Each end basket longeron that be arranged in parallel is fixedly connected between described preceding lower transverse beam and the back lower transverse beam; The Hanging Basket bed die is fixedly installed on the end basket longeron, and the Hanging Basket side form is positioned at the inboard of described main couple.
Compared with the prior art, the utility model beneficial effect is embodied in:
1, the utility model can hang in the cage of reinforcement integral body of finishing colligation in the bottom die platform space by the mode out of shape of improving Hanging Basket, directly carries out the concreting operation, has shortened the site operation cycle greatly.
2, the utility model has been selected more rational force way, and stressed clear and definite, simple in structure, the recycling rate of waterused of each working stage of Hanging Basket improves, greatly economization embedded bar material and default operation.
3, the utility model utilizes the upper space of lower support type Hanging Basket, the space of whole cage of reinforcement hoisted in position is provided, its method is simple and reliable, the case beam concrete segment of having built provides the space for the colligation of beam body cage of reinforcement, utilize the synchronism of tie with reinforcing bar and concrete construction and Hanging Basket walking, shorten the construction period.
4, the utility model is according to lower support type Hanging Basket Move Mode, and Hanging Basket is out of shape more stable, and state out of shape no longer becomes the principal element of restriction Hanging Basket safety, has also shortened the Hanging Basket travel time simultaneously.
