Abstract
The invention provides a collapse prevention steel reinforcement cage. The collapse prevention steel reinforcement cage comprises a steel reinforcement cage main bar (1) which is vertically wound into a cylindrical shape, an a steel reinforcement cage stirrup (2) which is tied on the steel reinforcement cage main bar. One side close to of the steel reinforcement cage main bar (1) is provided with a expanded-base space section steel bar bracket. The expanded-base space section steel bar bracket consists of a plurality of parallel transverse steel bars (3) whose end portions on one side can rotate with respect to the steel reinforcement cage main bar (1) and a plurality of vertical steel bars (4) arranged on the transverse steel bars (3) by preset gaps. The transverse steel bars (3) are provided with pulling elements (5) which are able to fold or spread the expanded-base space section steel bar bracket. This steel reinforcement cage is able to increase the bearing capacity of expanded-base filling pile effectively, and prevent collapse of the expanded-base pile expanded-base space section.
Description
Technical field
The present invention relates to a kind of anti-collapse reinforcing cage.
Background technology
The upper and lower size of anti-collapse reinforcing cage of the prior art is the same, in work progress, because the lithosphere above expansion base space section is due to deadweight, or during placing of concrete, when concrete casting highly reach a certain height, the lateral pressure of conducting oneself with dignity due to mixed earth exceedes the retaining wall side bearing capacity critical point outside stake holes, and concrete racks shaping expansion base space section, easily cause expanding caving in of base space section, thus occur the phenomenon of concrete, mud loss.
Summary of the invention
The technical problem to be solved in the present invention is to provide a kind of anti-collapse reinforcing cage, improves the intensity of reinforcing cage, avoids expanding caving in of base space section.
For solving the problems of the technologies described above, the anti-collapse reinforcing cage of one of the present invention, comprises the main muscle of the reinforcing cage vertically encompassing tubular 1 and the reinforcing cage stirrup 2 of colligation on the main muscle of reinforcing cage.The main muscle 1 of described reinforcing cage is provided with near the side of bottom and expands base space section Steel bar rack, described expansion base space section Steel bar rack can be provided with many reinforcing bar vertical bars 4 according to preset distance and form on the reinforcing bar horizontal stripe 3 pulling a parts side end parallel to each other by many can rotate relative to the main muscle of reinforcing cage 1 and described reinforcing bar horizontal stripe 3, and reinforcing bar horizontal stripe 3 is provided with and pulls parts 5.The through hole 7 that described reinforcing bar horizontal stripe 3 is arranged through described reinforcing bar vertical bar 4 relevant position, and described reinforcing bar horizontal stripe 3 is provided with protruding 6, the height of protruding 6 is greater than the gap between through hole 7 and reinforcing bar horizontal stripe 3.The described parts 5 that pull can be the parts of rope, connecting rod and so on, and the distance of spacing near end between described reinforcing bar horizontal stripe 3 is less than the distance away from end.
In the present invention, a kind of anti-collapse reinforcing cage, expands base space section and is provided with Steel bar rack, can improve the intensity of reinforcing cage, avoids expanding base space section and causes caving in due to the pressure of rock stratum, top, strengthen the supporting capacity of bottom-enlarging filling pile.

Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the present invention is further detailed explanation.
The anti-collapse reinforcing cage of one of the present invention, comprises the main muscle of the reinforcing cage vertically encompassing tubular 1 and the reinforcing cage stirrup 2 of colligation on the main muscle of reinforcing cage.The main muscle 1 of described reinforcing cage is provided with near the side of bottom and expands base space section Steel bar rack.Described expansion base space section Steel bar rack can be provided with many reinforcing bar vertical bars 4 according to preset distance and form on the reinforcing bar horizontal stripe 3 pulling a parts side end parallel to each other by many can rotate relative to the main muscle of reinforcing cage 1 and described reinforcing bar horizontal stripe 3.After exerting a force to pulling parts 5, as shown in Figure 1, expand base space section Steel bar rack and close up, reinforcing bar horizontal stripe 3 is posted by the main muscle 1 of reinforcing cage, and meanwhile, this reinforcing cage also along with reinforcing bar horizontal stripe 3 one-tenth and reinforcing cage main muscle 1 less parallel, thus hangs in stake holes by reinforcing bar vertical bar 4.
After launching to expand base space section support, as shown in Figure 2, reinforcing bar horizontal stripe 3 is opened, with as shown in Figure 2, reinforcing bar horizontal stripe 3 is opened, the angle that main 1 one-tenth, the muscle of reinforcing cage is vertical nearly, and reinforcing bar vertical bar 4 is parallel with reinforcing cage main muscle 1, now toward concrete perfusion in stake holes or cement grout, form bottom-enlarging filling pile as shown in Figure 3.
As shown in Figure 4, reinforcing bar vertical bar 4 and reinforcing bar horizontal stripe 3 junction are provided with through hole 7, reinforcing bar horizontal stripe 3 is through described through hole 7, reinforcing bar horizontal stripe 3 is provided with 2 projections 6 in through hole both sides, the height of protruding 6 is greater than the gap of through hole 7 and reinforcing bar horizontal stripe 3, effectively can prevent the slip of reinforcing bar vertical bar 4 on reinforcing bar horizontal stripe 3 like this, again can after pulling parts 5 to exert a force, reinforcing bar vertical bar 4 closes up along with reinforcing bar horizontal stripe 3, presses close on the main muscle 1 of reinforcing cage outside reinforcing cage.The described parts 5 that pull are arranged on reinforcing bar horizontal stripe 3 near reinforcing cage main muscle 1 side, and can be rope, also can be movably connected in the connecting rod on reinforcing bar horizontal stripe 3.
Obviously, those skilled in the art can carry out various change and modification to the present invention and not depart from the spirit and scope of the present invention.Like this, if these amendments of the present invention and modification belong within the scope of the claims in the present invention and equivalent technologies thereof, then the present invention is also intended to comprise these change and modification.
