Abstract
The utility model provides a deep basal pit integrated configuration annular inner support, includes reinforced concrete annular beam, stand and bracing piece, the stand erects in the foundation ditch bottom, and reinforced concrete annular beam is located the stand upper end, the bracing piece is located between reinforced concrete annular beam and the vertical supporting construction of foundation ditch, characterized by the bracing piece is steel structural rod, and its both ends are connected with reinforced concrete annular beam and the vertical supporting construction of foundation ditch respectively. The utility model discloses can simplify construction process, reduction of erection time, reduce cost implements deep basal pit excavation process and atress in-process, can in time adjust steel construction support member according to the foundation ditch monitoring condition, makes the member atress more reasonable, optimize.
Description
Technical field
The utility model relates to building, municipal engineering field, relates in particular in the deep foundation ditch combining structure annular to support.
Background technology
The annular inner supporting structure that the interior support of traditional deep foundation pit support is adopted mainly be made up of annular girder, column and support bar, but annular girder and support bar all adopts single reinforced concrete structure.Support in this reinforced concrete structure annular and have following problems: 1, annular girder in the annular inner supporting structure and support bar all adopt reinforced concrete structure can cause the construction period long; 2, full steel bar concrete annular inner supporting structure is removed long in time limit; 3, influence basement construction; Noise is big when 4, abolishing, and is big to the influence of surrounding enviroment; 5, full steel bar concrete annular inner supporting structure integral body is from great, and column and stand column pile are many, the cost height; 6, soil excavation inconvenience.
The utility model content
The purpose of this utility model is in order to solve the deficiency that the above-mentioned background technology exists, to propose interior support of deep foundation ditch combining structure annular of a kind of steel work and reinforced concrete structure combination, make it can simplify construction technology, the reduction of erection time, reducing cost.
For achieving the above object, the utility model adopts following technical scheme: support in a kind of deep foundation ditch combining structure annular, comprise steel bar concrete annular girder, column and support bar, described column is erected in the foundation ditch bottom, steel bar concrete annular girder position is by upright supports, described support bar is characterized in that described support bar is the steel work bar between steel bar concrete annular girder and the vertical supporting and protection structure of foundation ditch, its two ends are connected with the vertical supporting and protection structure of steel bar concrete annular girder and foundation ditch respectively.
What the link position of described steel work support bar and the vertical supporting and protection structure of foundation ditch preferably was arranged in the vertical supporting and protection structure of foundation ditch encloses the purlin place.
Weld with the metallic object that is embedded in the vertical supporting and protection structure of steel bar concrete annular girder and foundation ditch respectively at described steel work support bar two ends.
Preferred steel pipe of described steel work support bar or deformed steel.
The utlity model has following advantage:
1, the annular girder body adopts reinforced concrete structure, and other support bar adopts steel work, and it has given full play to the advantage of two kinds of structures, maximize favourable factors and minimize unfavourable ones, and the reinforced concrete structure convenient formation, material pressurized performance is good; Steel work is easy for installation as other straightway support bar, tension, pressure all can, the integral construction cycle is short.
2, interior support integral deadweight is light, and the column and the stand column pile of employing are few, and cost is low.
3, soil excavation is convenient.
4, the steel work support part divides dismounting convenient, and is little to underground cell structure construction infection, and the duration is short.
5, it is little to ambient influnence that dismounting is divided in the steel work support part.
6, because steel work has solderability, from heavy and light, stress performance good (pressurized, tension are all excellent), in implementing Deep Excavation and loading process, can monitor situation according to foundation ditch, in time adjust the steel work supporting rod, make rod member more reasonable stress, optimization.
Description of drawings
Fig. 1 is the vertical view that the utility model is positioned at deep foundation ditch.
Fig. 2 is an A-A sectional view among Fig. 1.
The specific embodiment
Referring to Fig. 1 and Fig. 2, the utility model comprises steel bar concrete annular girder 1, column 2 and support bar 3, and described column 2 is erected in the foundation ditch bottom, its upper end bearing bar concrete annular girder 1, and column 2 preferably adopts steel work, as the shaped steel of steel pipe, profile iron and so on.Described support bar 3 is the steel work bar, between steel bar concrete annular girder 1 and the vertical supporting and protection structure 4 of foundation ditch, its two ends respectively be embedded in steel bar concrete annular girder and the vertical supporting and protection structure of foundation ditch in enclose purlin place 5 be connected the metallic object welding.Described steel work support bar is deformed steels such as steel pipe or H shaped steel i iron, channel-section steel, angle steel, and the combination between the combination between the combination between steel pipe and the steel pipe, deformed steel and the deformed steel or steel pipe and the deformed steel.
Claims (4)
1, supports in a kind of deep foundation ditch combining structure annular, comprise steel bar concrete annular girder, column and support bar, described column is erected in the foundation ditch bottom, the steel bar concrete annular girder is by upright supports, described support bar is between steel bar concrete annular girder and the vertical supporting and protection structure of foundation ditch, it is characterized in that described support bar is the steel work bar, its two ends are connected with the vertical supporting and protection structure of steel bar concrete annular girder and foundation ditch respectively.
2, according to supporting in the described deep foundation ditch combining structure of claim 1 annular, what the link position that it is characterized in that described steel work support bar and the vertical supporting and protection structure of foundation ditch was arranged in the vertical supporting and protection structure of foundation ditch encloses the purlin place.
3, according to supporting in claim 1 or the 2 described deep foundation ditch combining structure annulars, it is characterized in that described steel work support bar two ends respectively with the metallic object welding that is embedded in the vertical supporting and protection structure of steel bar concrete annular girder and foundation ditch.
