Abstract
The utility model relates to a connector for T-shaped or I-shaped piles resisting the lateral force for a prefabricated reinforcing steel bar in the bracing of foundation pit and side slope engineering, two pile heads of two piles to be connected are thickened, an embedded force transmission bar, preserved grooves and connecting position holes are arranged, and inserted in the connecting position holes of the upper and lower pile heads through pin rods, the embedded transmission bars of the upper and lower pile heads are welded and connected through a short connecting bar, so that the T-shaped or I-shaped piles with lateral force resistant of a prefabricated reinforcing steel bar can be conveniently and quickly connected, in addition, the connector has larger bending resistant and shearing resistant capability, and is relatively low in manufacture cost.
Description
Technical field
The present invention relates to a kind of being connected of bracing of foundation pit and slope project prefabricated reinforced concrete lateral force resistance T shape or the stake of worker's shape that be used for.Prefabricated reinforced concrete T shape or the stake of worker's shape are the lateral force resistance stake types of promoting recently in bracing of foundation pit and the slope project, and the present invention provides a kind of simple, convenient and be connected pattern reliably for this type of T shape or the stake of worker's shape.
Background technology
Going along with sb. to guard him in engineering or the slope project of each field excavation construction of civil engineering, cantilever campshed, campshed add support or campshed to add anchor pole be the common form of going along with sb. to guard him.Traditional and the most the most frequently used campshed way is a bored pile at present, and there is constructs bothers, speed is slow, cost is high, need mud to transport outward shortcomings such as contaminated environment.Advantages such as prefabricated reinforced concrete lateral force resistance T shape or the stake of worker's shape are the new technologies of developing in recent years, and it has, and speed of application is fast, reliable in quality, cost are low are compared traditional bored pile, and its cost can save 30%～40%.But, designing pile length dark to excavation of foundation pit requires long situation, and the length of actual production stake is owing to be subjected to lifting and the transport restrictions can not be long, and what surpass limited length can only be at building-site with the stake spreading.How to solve the connection of this type of lateral force resistance fender post, for site operation provides a kind of convenience, jointing is extremely important reliably, is directly connected to this The application of new technique and popularization.
Summary of the invention
The present invention be directed to a kind of easy jointing of prefabricated reinforced concrete lateral force resistance T shape in the bracing of foundation pit engineering or the stake of worker's shape exploitation.This jointing have make simple, cost is low, on-the-spot location and advantage such as easy to connect, make the fender post after the connection under lateral forces, can bear the moment of flexure and the shearing of designing requirement, solved prefabricated reinforced concrete lateral force resistance T shape or the stake of worker's shape are subjected to length restriction in going along with sb. to guard him shortcoming.
The utility model solves the technical scheme that its technical problem adopts
Core feature of the present utility model is: prefabricated reinforced concrete lateral resisting T shape or worker's shape pile head, promptly descend pile crown (1) and last pile crown (2), it is the connector that is used to connect, its cross section thickeies, and has disposed the pre-buried power transmission muscle of pile crown (3), pile crown and reserved groove (4), pile crown positioning steel tube hole (5) and pile crown resistance to compression and strengthen (7b) (7c) (7d) (7e) of constructional reinforcement (7a); By inserting pile crown connection location and shearing resistance pin rod (6), the two-sided short muscle (9) that is welded to connect, realize that upper and lower pile crown connects fast, stake forms integral body about making, and can bear moment of flexure and shearing under lateral forces by designing requirement.
Description of drawings
Fig. 1 is the connection elevation of prefabricated reinforced concrete lateral force resistance T shape or the stake of worker's shape, Fig. 2 is the connection lateral view of prefabricated reinforced concrete lateral force resistance T shape or the stake of worker's shape, and Fig. 3 is the A-A section among Fig. 1, and Fig. 4 is the B-B section among Fig. 1, Fig. 5 is the C-C section among Fig. 1, and Fig. 6 is a pile crown way drawing.
Among the figure, the 1st, following pile crown; The 2nd, last pile crown; The 3rd, the pre-buried power transmission muscle of pile crown; The 4th, pile crown is reserved groove; The 5th, pile crown positioning steel tube hole; The 6th, pile crown connects location and shearing resistance pin rod; 7a, 7b, 7c, 7d, 7e are that the pile crown resistance to compression strengthens constructional reinforcement; The 8th, the pile body prestress reinforcement; The 9th, connect short muscle.
The specific embodiment
According to prefabricated reinforced concrete lateral force resistance T shape or the stake of worker's shape be located by connecting at the scene should construct simple, speed of application is fast and can bear the moment of flexure that caused by lateral force and the requirement of shearing, the specific embodiment of the invention is as follows:
1, down the stake cross section of pile crown (1) and last pile crown (2) thickeies, and has disposed (7b) (7c) (7d) (7e) of enhancing constructional reinforcement (7a), and increase pile crown intensity prevents that extrusion and collision makes pile crown impaired in the pile extension process.The length of thickening pile crown is between 500～1500mm, and thickness is between 200～500mm.
2, following pile crown (1) and last pile crown (2) both sides have disposed the pre-buried power transmission muscle of pile crown (3) of aligned in position, and every power transmission muscle head is provided with pile crown and reserves groove (4), and half exposes to make the pre-buried power transmission muscle of pile crown (3) head.The quantity of the pre-buried power transmission muscle of pile crown (3) and diameter can be selected between 2～4 and Φ 20～30mm according to the design force request.
3, the pile crown positioning steel tube hole (5) that has disposed aligned in position in the middle part of following pile crown (1) and the last pile crown (2), as the pin hole of pile crown connection location and shearing resistance pin rod (6), the diameter of pin rod (6) and steel pipe hole (5) internal diameter are complementary.Pile crown positioning steel tube hole (5) is connected the diameter of location and shearing resistance pin rod (6) and selects for use between Φ 25～40mm according to the design force request with pile crown.
4, after the stake scene was located by connecting up and down, pile crown connects the location and shearing resistance pin rod (6) is inserted in the pile crown positioning steel tube hole (5) of stake up and down, plays location and shearing resistance effect; The short muscle of connection (9) is placed in the pile crown of stake up and down and reserves in the groove (4), and be connected together with the pre-buried power transmission muscle of pile crown (3) double welding of stake up and down, play interconnect function, transmit the stress between the stake up and down, wherein, the diameter of the short muscle of connection (9) is identical with pre-buried power transmission muscle (3) with material.
