Abstract
The utility model provides a fender post with an anti-uplifting toothed groove for underground engineering. The bottom and the middle part of a fender post main body are respectively provided with an inward-sunken anti-uplifting toothed groove; and by adopting the structure, only local projection is added outside a structural plate for the anti-uplifting toothed groove, the stress requirement of the fender post can be satisfied by utilizing the thickness of a protection wall or a main bar protection layer, the overall stress effect of the structure and the fender post is good, simpleness in operation is achieved, and the overall waterproof performance is not damaged. The fender post is simple to produce and has low cost and simple process. The quality is easy to control, the difficulty that waterproof leakage of an anti-lifting pillar or an anti-lifting anchoring rod, the test period is long and the sealing of the soleplate is late can be overcome, and unfavorable influence for constructing a coping beam later can be avoided; and at the same time, through the construction of the coping beam, the fender post is safer and more reliable, and double insurance can be achieved.
Description
Technical field
The utility model provides a kind of underground construction with the fender post that has the anti-floating teeth groove, is applied to adopt the underground construction of castinplace pile as space enclosing structure, belongs to the architectural engineering construction technique field.
Background technology
The city underground underground station often relates to the structure anti-floating, and the design of traditional anti-floating adopts uplift piles, uplift anchor, bottom girder tighten control distortion, capping beam etc.
Adopt uplift pile and uplift anchor to prevent penetration by water to base plate; Binding site is as controlling the improper percolating water that very easily causes; Perform uplift pile simultaneously and can relate to bigger safety problem again, the same resistance to plucking that all need carry out with uplift anchor is tested, and early seals deleterious impact for base plate;
Adopting a kind of method of anti-floating capping beam is to need behind the top board construction pile body to be handled, cutter stake bar planting construction capping beam, and the method operating expenses is higher, and simultaneously, the bar planting connection is compared often shorter with the life-span of structure, and quality is unreliable.Adopting anti-floating capping beam another kind method is to reduce going along with sb. to guard him the dowel crown beam; Guan Liang strengthens and interlocks in order to capping beam between later stage and structure roof; But the method Guan Liang is lower than original ground, and upper slope is protected improper easy generation moderate finite deformation, and the operating space was little when capping beam was poured into a mould between top board and hat beam simultaneously; Leakiness is poured into a mould on top easily, and is very unfavorable to later anti-floating controlled deformation.
Summary of the invention
The utility model provides a kind of underground construction with the fender post that has the anti-floating teeth groove, and it is more convenient flexibly that capping beam, anti-float anchor rod, uplift pile are set, and do not influence the outer waterproof of structure.
The technical solution of the utility model is following:
Comprise that fender post body and interior cage of reinforcement thereof constitute, be respectively equipped with an anti-floating teeth groove that caves inward at the bottom and the medium position of fender post body; Bend according to designing requirement master muscle at the structural slab position during fender post construction; Accurately locate and to guarantee that position deviation meets the demands solid in order to later stage anti-floating teeth groove down; Adopt mortar to smear benefit the anti-floating teeth groove behind the excavation pit, teeth groove and structural entity cast, stressed jointly to realize stake and agent structure.
The good effect of the utility model is: adopt structure anti-floating teeth groove only need outside structural slab, increase outside the part and choose; Fender post utilizes retaining wall or main tendon protective layer thickness can satisfy force request; The whole stressed effect of structure and fender post is good, easy and simple to handle, and water tight integrity is not damaged.The utlity model has and be simple and easy to work, with low cost, technology is simple.Quality is easy to control, has overcome the water leakage and the late difficult problem of test period elongated base plate sealing of uplift pile or uplift anchor, avoids the later stage to perform the adverse effect of capping beam, can combine capping beam to perform simultaneously, safety and reliability, double insurance.
Description of drawings
Fig. 1 is the utility model structure principle chart;
Wherein, 1, fender post body; 2, anti-floating teeth groove; 3, cage of reinforcement.
The specific embodiment
According to shown in Figure 1; The utility model comprises that fender post body 1 and interior cage of reinforcement 3 thereof constitute; The bottom of fender post body 1 and medium position are respectively equipped with an anti-floating teeth groove 2 that caves inward; In fender post when construction,, accurately locate and to guarantee that position deviation meets the demands solid in order to the down of later stage anti-floating teeth groove 2 according to the bending of designing requirement master muscle at the structural slab position, and the anti-floating teeth groove 2 with fender post body 1 behind the excavation pit adopts mortars to smear benefit; Anti-floating teeth groove 2 and structural entity cast, stressed jointly to realize fender post and agent structure.
Claims (1)
1. a underground construction comprises that with the fender post that has the anti-floating teeth groove fender post body and interior cage of reinforcement thereof constitute, and it is characterized in that: the bottom of fender post body and medium position are respectively equipped with an anti-floating teeth groove that caves inward.
