Description
Technical field
It is espespecially a kind of space saving cradle structure, outstanding for several the present invention relates to bridge suspended pouring construction apparatus field
Hanging Basket system and a kind of construction method of several cantilever pourings that arm is poured.
Background technology
Hanging Basket is a kind of load-carrying members that can be slided or roll along back, is a movable operation platform.It anchors outstanding
Hang in the front end beam section constructed, the template of next beam section, reinforcing bar, prestress pipe can be carried out on Hanging Basket and is installed, is mixed
The operations such as solidifying soil perfusion and prestressed stretch-draw, grouting.After the circulation for completing a stage, Hanging Basket is to move forward and fixed, under progress
The outstanding filling of one section, is so recycled to cantilever pouring completion.Hanging Basket typically each has following part：It is load-carrying members, outstanding
Crane system, anchor, walking system and workbench.Wherein, load-carrying members are the main bearing members of Hanging Basket, and it bears to apply
Construction equipment and the total weight for newly pouring stage concrete, mainly include main longitudinal grider and preceding upper and lower crossbeam, rear upper and lower crossbeam, purlin
Frame, is usually to be welded into box-type section by shaped steel or steel plate group per part.
Traditional cantilever pouring template at least needs the length between 450mm, i.e., A, B as shown in Figure 1 from cradle structure outward flange
Degree need to be 450mm.This causes both sides problem：
First be design concrete structure apart from existing structure it is nearer when, can due to no sufficient space arrange cradle structure,
So that can not be constructed.
Next to that when carrying out two width or even several cantilever pourings, space is smaller between two width independence concrete structures under many situations,
Less than 900mm.Now due to arranging that two cradle structures carry out parallel synchronous traveling operation without sufficient space, can only misplace construction,
And the cradle structure first constructed also needs to stay enough advance spaces for the cradle structure progress cantilever pouring of another width, greatly extension
Duration.
The content of the invention
It is an object of the invention to provide a kind of space saving cradle structure, realize that cradle structure occupies sky under Construction State
Between diminution.A kind of Hanging Basket system and a kind of construction party of several cantilever pourings for several cantilever pourings is provided again
Method, realizes that cradle structure synchronous parallel is processed in several cantilever pourings.
The technical scheme that the present invention is provided is as follows：A kind of space saving cradle structure, including it is truss, preceding entablature, preceding
Sill, rear entablature and rear sill, pass through some first suspension rod phases between the rear entablature and the rear sill
Connection, the preceding entablature is connected with the preceding sill by some second suspension rods, and outermost two described first are hung
Bar passes through the hole to be provided for having completed concrete structure to set；
Complete to be connected with walking suspension bracket in concrete structure, being provided with the walking suspension bracket can be along Hanging Basket direct of travel
The nose girder of slip, it is described to lead fine strain of millet positioned at the unilateral or bilateral for having completed concrete structure；Outermost first suspension rod and most
Second suspension rod in outside is affixed with the nose girder respectively, is synchronized with the movement with the nose girder；Outermost two described first

Further, the truss of the 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 provided by the present invention, can bring following at least one beneficial effect：
1st, the Hanging Basket arrangement space when design concrete structure is nearer apart from existing structure, building structure can be solved the problems, such as
Design is more flexible, various.
2nd, for the multiple independent less situations of concrete structure spacing of several cantilever pourings, enough spaces are hung with multiple
Basket structure synchronization side by side parallel is constructed, and greatly reduces the duration.
3rd, a Guide beam structure is additionally increased, structure design is simple, cost economy, and can reach that traditional cantilever pouring is same
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
Space saving cradle structure is stated, the number of the space saving cradle structure is identical with the number of cantilever width, it is each described
Space saving cradle structure processes a width cantilever respectively.
Two or more independent less situations of concrete structure spacing for several cantilever pourings, because space saving is hung
The outermost suspension rod of basket structure is worked as between the construction of cradle structure side by side parallel, formwork for placing inside formwork for placing
Limited away from not taken up space by Hanging Basket.The space saving Hanging Basket knot described in side by side two or more so can be achieved
Structure synchronous processing, greatly reduces the duration.
