Description
Technical Field
The utility model relates to a building bored concrete pile construction technical field, concretely relates to major diameter strikes bores bored concrete pile steel reinforcement cage anti-floating structure.
Background
In the construction process of the concrete filling pile, the force borne by the reinforcement cage is the resultant force of floating friction generated by upward movement of slurry and concrete mixture and the friction of the concrete buried in the lower part, the self weight of the reinforcement cage and the pressure generated by fixation of the reinforcement cage, if the floating support acting force exceeds the downward acting force, the steel reinforcement cage floats upwards, the construction quality of the bored pile is directly influenced, therefore, the anti-floating problem of the large-diameter cast-in-place pile reinforcement cage is a key problem influencing the structural quality, the anti-floating and anti-floating measures of the cast-in-place pile reinforcement cage lead to the reinforcement cage floating upwards in the concrete pouring process, the pile foundation quality is influenced, the traditional method adopts the steps that the reinforcement cage steel bars are welded on the pile casing to carry out anti-floating fixation, however, the method bends the reinforcing steel bars to influence the structure quality, and each pile foundation needs to be welded, so that time and labor are wasted, and materials are wasted.
Disclosure of Invention
The anti structure that floats of bored concrete pile steel reinforcement cage is bored in major diameter impact to the not enough of above-mentioned prior art, its simple structure, easy dismounting, quick has reduced workman's intensity of labour, and save material has stronger practicality.
In order to solve the technical problem, the utility model discloses the technical scheme who takes is, a major diameter strikes bores bored concrete pile steel reinforcement cage anti-floating structure, including protecting a section of thick bamboo, still include a plurality of correspondences and weld the arc ring on protecting a section of thick bamboo for the cover is located on the steel reinforcement cage vertical reinforcement and top confined vertical steel pipe, and is inserted and locates the intra-annular horizontal steel pipe of arc, is equipped with the steel pipe clamp that is used for coming the two to be connected between vertical steel pipe and horizontal steel pipe, still includes that both ends are connected respectively in protecting a section of thick bamboo and the stake machine on be used for fixed coupling assembling who protects a section of thick bamboo.
Foretell major diameter strikes and bores bored concrete pile steel reinforcement cage anti-floating structure, coupling assembling includes by dual-purpose in respectively protecting the arc of a section of thick bamboo inner wall and outer wall contact, and locate the joint spare that is used for and protects a section of thick bamboo joint that is used for of connecting the two at two arc tops, be equipped with first slope side pipe on the connecting plate, be equipped with a footpath and be less than the second slope side pipe of first slope side pipe on stake machine, still including inserting the first support side pipe of locating in first slope side pipe, and the second that both ends were pegged graft with second slope side pipe and first support side pipe respectively supports side pipe, first, be equipped with the bolt hole that is used for the two to connect on two support side pipes, be equipped with stud in the bolt hole.
The utility model discloses the beneficial effect of major diameter percussion drill bored concrete pile steel reinforcement cage anti-floating structure is, its simple structure, and save material has stronger practicality. Combine a whole with a steel reinforcement cage and a pile casing through horizontal steel pipe, vertical steel pipe, joint spare and arc ring, coupling assembling will protect a section of thick bamboo and be connected with the stake machine, and is more firm to the fixed of a section of thick bamboo, and then prevents steel reinforcement cage come-up, and coupling assembling easy dismounting, quick, reduced workman's intensity of labour, effectively improve bored concrete pile efficiency of construction.

Detailed Description
The invention is described in detail below with reference to the figures and the embodiments.
As shown in fig. 1, 2, 3 and 4, the anti-floating structure of the large-diameter percussion drill bored concrete pile steel reinforcement cage comprises a protective casing 1, a plurality of arc rings 2 correspondingly welded to the protective casing, a vertical steel pipe 3 which is sleeved on the vertical steel bars of the steel reinforcement cage and has a closed top, and a horizontal steel pipe 4 which is inserted in the arc rings, wherein a steel pipe clamp 5 for connecting the vertical steel pipe and the horizontal steel pipe is arranged between the vertical steel pipe and the horizontal steel pipe, and the anti-floating structure further comprises a connecting assembly which is connected with the protective casing and a pile driver 14 at two ends and is used for fixing the protective casing. Coupling assembling includes by dual-purpose in protecting an inner wall and outer wall contact's arc 6 respectively, and locate two arc tops be used for with the joint spare 13 of a protection section of thick bamboo joint that is used for of connecting 7 constitution of the two, be equipped with first slope side pipe 8 on the connecting plate, be equipped with a footpath on the stake machine and be less than the second slope side pipe 9 of first slope side pipe, still including inserting the first support side pipe 10 of locating in first slope side pipe, and both ends respectively with second slope side pipe and the second support side pipe 11 of the square grafting of first support side pipe, first, be equipped with the bolt hole that is used for the two to be connected on the second support side pipe, be equipped with stud 12 in the bolt hole. The connecting assembly is used for connecting the pile casing with the pile machine and can be arranged in a mirror image mode, and the stability of the pile casing is further guaranteed.
Of course, the above description is not intended to limit the present invention, and the present invention is not limited to the above examples, and the changes, modifications, additions or substitutions made by those skilled in the art within the scope of the present invention should also belong to the protection scope of the present invention.
