Abstract
The utility model relates to a steel reinforcement cage with spacer bar, which comprises main bars, spiral steel bars and annular reinforcement bars; wherein, the main bars are evenly distributed along circumference and are welded together to form a cylindrical steel reinforcement cage through the spiral steel bar on the lateral side of the main bars, annular reinforcement bars are welded on the inner side of the cylindrical steel reinforcement cage coaxially, the main bars on the lower end of the cylindrical reinforcement cage gradually converge towards axis to form an inverted conical steel reinforcement framework, and a spacer bar is coaxially welded with the cylindrical steel reinforcement cage in the center of the bottom end of the inverted conical steel reinforcement framework. The steel reinforcement cage with spacer bar has simple integral structure, scientific and reasonable design, simple fabrication technique and lower production cost, convenient mounting, saves time and labor, and has better positioning ability.
Description
Technical field
The utility model relates to the reinforcing cage field, especially a kind of reinforcing cage with spacer bars.
Background technology
Reinforcing cage is one of foundation of civil work piling raw material commonly used, and its effect mainly is an intensity of strengthening foundation.The structure of reinforcing cage commonly used is to be uniformly distributed along the circumference and to be welded together by outside spiral reinforcement by isometric main muscle in the foundation of civil work construction at present, every interval is provided with a hoop reinforcing rib for one section on the main muscle, the reinforcing cage of this structure is employed fluid concrete foundation ditch formerly, the back adds in the job practices of reinforcing cage, though also can reinforcing cage be headed in the foundation ditch of fluid concrete by vibrating device, but there are the following problems always for this process: (1). the reinforcing cage location difficulty, skew easily in the construction, cause reinforcing cage bump foundation pit walls, therefore the reinforcing cage that at every turn all needs to extract certain-length could continue piling, prolong the piling time, reduced the efficient of piling; (2). reinforcing cage since during jacking judder be offset, be easy to cause the damage of reinforcing cage, increased the time of maintenance cost and piling; (3). the reinforcing cage of said structure just needs the vibration jacking in the piling beginning, has reduced concrete fullness coefficient.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, and a kind of reinforcing cage with spacer bars is provided, and this reinforcing cage is simple in structure, design science is reasonable, and manufacture craft is simple, and cost of production is lower, easy for installation, time saving and energy saving, have stationkeeping ability preferably.
The utility model solves its technical problem and is achieved through the following technical solutions:
A kind of reinforcing cage with spacer bars, constitute by main muscle, spiral reinforcement and hoop reinforcing rib, main muscle is uniformly distributed along the circumference and is welded to each other formation one cylindrical reinforcing bar cage by the spiral reinforcement outside it, the inboard coaxial welding of this cylindrical reinforcing bar cage has the hoop reinforcing rib, it is characterized in that: the main muscle of cylindrical reinforcing bar cage lower end all closes up to the axle center convergent and forms a turbination cage of reinforcement, and the bottom center of this turbination cage of reinforcement and column type reinforcing cage coaxial welding have a location reinforcing bar.
And the outside continuity of described turbination cage of reinforcement is welded with spiral reinforcement.
And the outside of described turbination cage of reinforcement is welded with the hoop reinforcing rib.
Advantage of the present invention and beneficial effect are:
1. the reinforcing cage that originally has spacer bars is made of main muscle, spiral reinforcement and hoop reinforcing rib, the main muscle of wherein cylindrical reinforcing bar cage lower end all forms a turbination cage of reinforcement to the axle center convergent, the bottom center welding one location reinforcing bar of this turbination cage of reinforcement, this kind reinforcing cage structure can increase the stability when installing, avoid reinforcing cage to damage because of the collision foundation pit walls, shorten the time of whole piling, improved operating efficiency.
2. the bottom center of turbination cage construction that originally has the reinforcing cage of spacer bars is fixed with spacer bars does not need to vibrate jacking mechanism in initial installation process, rely on self gravitation can sink in the concrete, reduced concrete influence has especially been improved concrete fullness coefficient.
3. the utility model overall structure is simple, and design science is reasonable, and manufacture craft is simple, and cost of production is lower, and is easy for installation and time saving and energy saving, has the reinforcing cage with spacer bars of stationkeeping ability preferably.
Description of drawings
Fig. 1 is a front view of the present utility model;
Fig. 2 is that the A-A of Fig. 1 is to the cross section cutaway view Amplified image.
The specific embodiment
The utility model is described in further detail below by specific embodiment, and following examples are descriptive, is not determinate, can not limit protection scope of the present invention with this.
A kind of reinforcing cage with spacer bars, by main muscle 1, spiral reinforcement 3 and hoop reinforcing rib 2 constitute, the quantity of this main muscle can be calculated according to the needs of operating mode, the quantity of present embodiment main muscle shown in the drawings is eight, eight main muscle are uniformly distributed along the circumference and the spiral reinforcement welding by its outside forms a cylindrical reinforcing bar cage, the inboard coaxial welding of this cylindrical reinforcing bar cage has the hoop reinforcing rib, the quantity of this hoop reinforcing rib can be provided with according to the needs of operating mode, the quantity of present embodiment hoop reinforcing rib shown in the drawings is three, eight main muscle of wherein cylindrical reinforcing bar cage lower end all close up to the axle center convergent and form a turbination cage of reinforcement, the bottom center of this turbination cage of reinforcement and reinforcing cage coaxial welding have a location reinforcing bar 4, and the outside continuity of turbination cage of reinforcement is welded with spiral reinforcement and hoop reinforcing rib.
The utility model operating principle:
After the foundation ditch of foundation of civil work is accomplished fluently, concrete perfusion, the reinforcing cage that will have spacer bars is connected with the vibration jacking mechanism, because installing and locating reinforcing bar and reinforcing cage lower end main reinforcement have formed a turbination cage of reinforcement, so when initial placement reinforcing cage, do not need vibration, only need to rely on the self gravitation of reinforcing cage to get final product, when reinforcing cage can not carry out jacking again by self gravitation, the Vibration on Start-up jacking mechanism, the reinforcing cage that will have spacer bars is in place.
Claims (3)
1. reinforcing cage with spacer bars, constitute by main muscle, spiral reinforcement and hoop reinforcing rib, main muscle is uniformly distributed along the circumference and is welded to each other formation one cylindrical reinforcing bar cage by the spiral reinforcement outside it, the inboard coaxial welding of this cylindrical reinforcing bar cage has the hoop reinforcing rib, it is characterized in that: the main muscle of cylindrical reinforcing bar cage lower end all closes up to the axle center convergent and forms a turbination cage of reinforcement, and the bottom center of this turbination cage of reinforcement and column type reinforcing cage coaxial welding have a location reinforcing bar.
2. the reinforcing cage with spacer bars according to claim 1 is characterized in that: the outside continuity of described turbination cage of reinforcement is welded with spiral reinforcement.
