Abstract
Disclosed is a precast concrete element suspended connecting device comprising an embedded reinforcement and a suspended ring, one end of the embedded reinforcement is fixedly connected with a screw cap, the suspended ring is fixedly connected with one end of a bolt, the screw cap and the bolt are connected actively, the suspended ring is high-strength cable or a welded integration of steer ring and bolt. One or more bends are provided at the tail of the embedded reinforcement according to bearing ability needs. The utility model embeds reinforcement with screw cap in the building block and is engaged with screw with suspended ring, the device is not only convenient to connect and suspend, but also is instant to detach the suspended ring after suspending thereby saving late cutting action, the detached suspended ring is reusable thereby saving reinforcement and reducing project cost, the functions of the connecting device are extensive.
Description
Technical field
The utility model relates to the technological improvement of concrete prefabricated element, is specifically related to a kind of linkage that makes things convenient for the concrete prefabricated element lifting.
Background technology
Develop rapidly along with architectural construction technology, the prefabricated units of steel concrete are used widely in growing field, for example bridge, pipeline tunnel, industry and civilian construction or the like, but the employing concrete prefabricated element is the reduction of erection time both, the surcharges such as rack template of also having saved site operation simultaneously reduce construction costs.The lifting of concrete prefabricated element is for convenience installed, and the common practice is when embedded bar at present, adopts the way that exposes joint.Promptly,, crane lifts by crane installation so that linking up with at the surperficial reserved steel bar hoisting ring of prefabricated units.The problem that this structure exists be these reserved steel bar hoisting rings after lifting is finished, not only need with special machine with embedded bar expose suspension ring cutting, and cut ring can not reuse, and can only reclaim as scrap iron, must increase construction cost.
The utility model content
At the prior art above shortcomings, the purpose of this utility model provides a kind of convenient a kind of concrete prefabricated element lifting linkage that lifts, effectively reduces construction cost.
The purpose of this utility model is achieved in that a kind of concrete prefabricated element lifting linkage, comprises embedded bar and hoisting ring, it is characterized in that the fixedly connected nut of an end of embedded bar, the fixedly connected bolt of hoisting ring; Described nut and bolt flexibly connect.
Described hoisting ring is welded by high strength steel strand or steel loop and bolt.
The afterbody of described embedded bar is provided with one or more according to the needs of bearing capacity and bends up.
Compared to existing technology, the utlity model has following advantage:
1,, and be used with the bolt of band suspension ring by the pre-buried reinforcing bar that has nut in prefabricated units, not only convenient the connection and lifting, and also lifting goes back the quick release suspension ring after finishing, and saved the later stage cutting action;
2, the hoisting ring (strap bolt) after the dismounting can repeated multiple times use, and has saved reinforcing bar, reduces construction costs;
3, guarantee that as seen building unit has smooth beautiful outward appearance, have only the nut mouth;
4, the function of described linkage can also be expanded: such as the installation that is used for the bridge guard against error railing, perhaps installation of stair or the like in the building construction can substitute the way that is connected of traditional boring and setscrew, improves speed of application;
5, the afterbody of embedded bar bends up and can improve bearing capacity, and has transmission force property preferably, and the problem of effectively avoiding stress to concentrate allows Edge Distance less, can be used for thin prefabricated units;
6, production technology is simple.
Description of drawings
Fig. 1 is the structural representation of the utility model one embodiment;
Fig. 2 is the partial top view of Fig. 1;
Fig. 3 is a kind of function extended mode of the utility model schematic diagram.
The specific embodiment
As shown in Figure 1 and Figure 2, concrete prefabricated element lifting linkage of the present utility model flexibly connects by the embedded bar 5 of the fixedly connected nut 4 of an end with nut 4 and the hoisting ring 1 of strap bolt 2 is formed, and described nut 4 flexibly connects with bolt 2; Hoisting ring 1 is welded by high strength steel strand or steel loop and bolt.Embedded bar 5 is located among the concrete prefabricated element 1O during use, and nut 4 is located at the surface of concrete prefabricated element 10.Among the figure, F is that the concrete prefabricated element lifting is subjected to force direction.
The afterbody of described embedded bar is provided with one or more according to the needs of bearing capacity and bends up 6.
The length of reserved steel bar 5 is selected according to bearing capacity, and bearing the member dead weights of different sizes, the afterbody of reinforcing bar can be provided with as required and one or morely bend up 6, thereby can better bear the shear force that is transmitted by nut in hoisting process.Simultaneously, shearing bearing capacity can also be greatly enhanced by the chevron shaped auxiliary reinforcement 7 on the embedded bar vertical direction.Auxiliary reinforcement 7 can effectively be connected by plastics pullover 3 with main reinforcement 5.
Adopt the utility model by bolt and nut suspension ring are connected easily with prefabricated units, lifting can also be dismantled after finishing fast, has saved the later stage cutting action; And suspension ring can repeated multiple times use saving reinforcing bar, reduction construction costs; Guarantee that simultaneously as seen building unit has smooth beautiful outward appearance, have only the nut mouth.
Referring to Fig. 3, the function of described linkage can also be expanded: connect guardrail 9 by bolt 8, substitute the way that is connected of traditional boring and setscrew, improve speed of application greatly.Such as the installation of stair in the railing of bridge road or the building construction or the like.
