Description
Technical field
This utility model belongs to contrary sequence method technical field of building construction, particularly relates to a kind of variable cross-section wall vertical support structure for contrary sequence method.
Background technology
Reverse construction main process is first along building basement axis or around construct diaphram wall or other supporting construction, interior of building has off position to build or lays intermediate sup-poning pile and post simultaneously, bears the support of superstructure deadweight and construction loads before base plate back cover as construction period.Then construct the beam slab floor structure on one layer of ground, as the support that diaphram wall rigidity is very big, successively downward earth excavation and build each layer underground structure subsequently, until base plate back cover.Simultaneously as the floor structure on one layer of ground completes, create condition for Superstructure Construction, it is possible to upwards successively carry out the construction of superstructure simultaneously.Such ground is upper and lower constructs simultaneously, until engineering terminates.
Current with the tier building of basement, skyscraper adopt full-reverse method construction time, need to having off position to build or laying intermediate sup-poning pile and column at interior of building, before base plate back cover, bear superstructure deadweight and the support of construction loads as construction period；This requires that vertical support structure has sufficiently large bearing capacity and stiffness, to ensure that the construction of superstructure can be unrestricted before bottom slab concreting.Meanwhile, need by arranging that shaped steel carries out lateral connection between vertical support column in work progress, thus ensureing that vertical upright column meets stability requirement.Need when later stage Underground Construction to relevant position to cut off column and connection shaped steel, then the structure such as basement wall and post of again constructing, cause the waste of engineering time and resource.
Utility model content
The purpose of this utility model is to provide the variable cross-section wall vertical support structure for contrary sequence method, when solving the construction of existing band basement tier building, intermediate sup-poning pile and column need to be set at interior of building, vertical support structural bearing capacity and rigidity requirement is high, need to arrange the technical problems such as shaped steel carries out lateral connection, complicated integral structure, operation sequence is many, subsequent treatment is loaded down with trivial details simultaneously.
To achieve these goals, this utility model provides a kind of variable cross-section wall vertical support structure for contrary sequence method, and described supporting structure is arranged in foundation ditch groove, comprising:
Basement wall, described basement wall includes basement wall steel reinforcement cage and basement wall body concrete；Described basement wall has the first thickness；
Wall foundation, described wall foundation includes wall foundation steel reinforcement cage and wall foundation concrete；Described wall foundation downwardly extends from the bottom of basement wall；Described wall foundation has the second thickness, and described second thickness is more than the first thickness；
The junction of basement wall and wall foundation is basement bottom board top mark high position.
This utility model is as above for the variable cross-section wall vertical support structure of contrary sequence method, and further, the reinforcing bar bottom basement wall steel reinforcement cage extends at an angle obliquely, integral with the bar connecting at steel reinforcement cage top, wall foundation.
This utility model is as above for the variable cross-section wall vertical support structure of contrary sequence method, and further, the overall structure of described basement wall and wall foundation is convex shape.
The beneficial effects of the utility model are:
First, the basis that cross section, this utility model wall foundation is big, bearing capacity and stiffness is all higher than routine, it is possible to when ensureing adverse construction method, superstructure height is unrestricted constructs.
Secondly, later stage only need to when basement is excavated to place absolute altitude by internal for basement form removable, while part basement wall of having constructed in advance, avoid body of wall cut and cut column, connect the work such as shaped steel, the cost duration is saved again in environmental protection, it is put things right once and for all, achieves many things at one stroke.
Basement wall, slightly larger than basement wall body section, is inserted in this wall foundation by cross section, this utility model wall foundation, forms a kind of vertical variable cross-section wall type component being made up of basement wall and wall foundation.Compared with common diaphram wall, this component basement wall body thickness less (mostly generally being 300mm or 400mm), the minimum thickness that conventional grooving machinery is capable of is 600mm, if body of wall all being made 600mm thickness, later stage carries out cutting can cause certain wasting of resources, do not meet the construction concept of environmental protection, also can strengthen workload simultaneously.
Tier building, skyscraper adopt frame structure, shear wall structure or combination, vertical force transferring structure going down load can be it can be used as, thus avoid later stage cutting column and the workload brought of shaped steel and waste, basement part-structure body of wall of also having constructed in the lump simultaneously.Now for providing enough bearing capacity and stiffness, need to be greatly increased a footpath or stake is long according to accepting upper load based on conventional supporting pile, thus bringing unnecessary waste, therefore base foundation is designed to wall foundation, and by integral to the reinforcing bar on basis and the reinforcing bar binding of upper wall body.This foundation pattern is bigger due to cross section, also higher with the bearing capacity that surrounding soil combined effect provides, there is bigger rigidity and stability in the large, with the load of the common degree superstructure of basement wall, it is ensured that the construction of superstructure can be smoothed out before bottom slab concreting.
