Description
Technical field
The present invention relates to bridge suspended pouring construction apparatus field, espespecially a kind of space saving cradle structure, hang for several
Hanging Basket system and a kind of construction method of several cantilever pourings that arm pours.
Background technology
Hanging Basket is a kind of load-carrying members that can slide along back or roll, and is a movable operation platform.Its anchoring is outstanding
Hang in the front end beam section of construction, the template of next beam section, reinforcing bar, the installing of prestress pipe can be carried out on Hanging Basket, mix
Solidifying soil perfusion and the operation such as prestressed stretch-draw, grouting.After completing the circulation in a stage, Hanging Basket moves forward and fixing, under carrying out
The outstanding filling of one sections, is so recycled to cantilever pouring and completes.Hanging Basket typically each has following ingredient：Load-carrying members, outstanding
Crane system, anchor, walking system and work platformses.Wherein, load-carrying members are the main bearing member of Hanging Basket, and it bears and applies
Construction equipment and the total weight newly pouring stage concrete, main inclusion main longitudinal grider and front upper and lower crossbeam, rear upper and lower crossbeam, purlin
Frame, every part is usually and is welded into box-type section by shaped steel or steel plate group.
Traditional cantilever pouring template at least needs 450mm from cradle structure outward flange, i.e. length between A, B as shown in Figure 1
Degree need to be 450mm.This causes both sides problem：
First be design concrete structure apart from existing structure nearer when, can due to do not have sufficient space arrangement cradle structure,
So that cannot be carried out constructing.
When next is by two width or even several cantilever pourings, under a lot of situations, between two width independence concrete structures, space is less,
Less than 900mm.Now because no sufficient space arranges that two cradle structure carry out parallel synchronous traveling operation, can only misplace construction,
And the cradle structure first constructed also needs the cradle structure for another width to carry out cantilever pouring stays enough advance spaces, greatly extend
Duration.
Content of the invention
It is an object of the invention to provide a kind of space saving cradle structure, realize cradle structure under Construction State and occupy sky
Between reduce.Provide a kind of Hanging Basket system for several cantilever pourings and a kind of construction party of several cantilever pourings again
Method, realizes cradle structure synchronous parallel processing in several cantilever pourings.
The technical scheme that the present invention provides is as follows：A kind of space saving cradle structure, including truss, front entablature, front
Sill, rear entablature and rear sill, by some first suspension rod phases between described rear entablature and described rear sill
Connect, described front entablature is connected by some second suspension rods with described front sill, and outermost two described first are hung
Bar passes through the hole to be provided setting having completed concrete structure；
Complete to be connected with walking suspension bracket in concrete structure, described walking suspension bracket is provided with can be along Hanging Basket direct of travel
Slide nose girder, described lead fine strain of millet be located at the described unilateral or bilateral having completed concrete structure；Outermost described first suspension rod and
Described second suspension rod in outside is affixed with described nose girder respectively, is synchronized with the movement with described nose girder；Outermost two described first
It is provided with adapter, described adapter is located above described nose girder on suspension rod.
Outermost for cradle structure suspension rod is passed through completed concrete structure setting, in the inner side of formwork for placing, eliminates
Original structure middle hanger is located at the space additionally occupying outside formwork for placing.On the one hand design concrete structure can be met apart from existing
The installation space problem of cradle structure when building is nearer, on the other hand for two or more independent concretes of several cantilever pourings
The less situation of structure pitch, has enough spaces to make cradle structure synchronization side by side parallel construction, greatly reduces the duration.
Further, described walking suspension bracket is provided with plain-barreled roll, moves ahead for nose girder sliding.The nose girder resistance of motion is little, Hanging Basket
Structure is run smooth.
Further, described completed to be provided with preburied component in concrete structure, described walking suspension bracket is completed with described
Concrete structure is welded to connect by described preburied component.
Further, described nose girder is Two bors d's oeuveres nose girder.
Further, positioned at outermost described second suspension rod apart from formwork for placing edge 1000-2000mm.
Further, the truss of described space saving cradle structure is triangular truss.Triangular structure is stable, can
There is more uniform distribution of force in cradle structure, advance reliable and stable.
The space saving cradle structure being provided by the present invention, can bring following at least one beneficial effect：
1st, can solve the problems, such as when design concrete structure Hanging Basket arrangement space when nearer, building structure apart from existing structure
Design is more flexible, various.
2nd, the less situation for the multiple independent concrete structure pitch of several cantilever pourings, has enough spaces can multiple hang
Basket structure synchronization side by side parallel is constructed, and greatly reduces the duration.
3rd, additionally increase a Guide beam structure, structure design is simple, cost economy, and it is same to reach traditional cantilever pouring
Equal strength and rigidity.
The invention also discloses a kind of Hanging Basket system for several cantilever pourings, it includes：The multiple institutes being arranged side by side
State space saving cradle structure, the number of described space saving cradle structure is identical with the number of cantilever width, described in each
Space saving cradle structure processes a width cantilever respectively.
The less situation of two or more independent concrete structure pitch for several cantilever pourings, because space saving is hung
The outermost suspension rod of basket structure is within formwork for placing, therefore when the construction of cradle structure side by side parallel, between formwork for placing
Limited away from not taking up space by Hanging Basket.So can achieve two or more described space saving Hanging Basket knots side by side
Structure synchronous processing, greatly reduces the duration.
The invention also discloses a kind of construction method of several cantilever pourings, comprise the following steps：
S10, complete one group of 0# block construction of several cantilevers；
S20, in the respectively connect setting walking suspension bracket of 0# block described in a group, and arrange and can advance along Hanging Basket on walking suspension bracket
