Abstract

The utility model provides a square pile with tooth-shaped joints. The square pile comprises an upper pile body and a lower pile body, wherein the pile head of the upper pile body is provided with the lower tooth-shaped joints which are fixedly connected with the upper pile body, the periphery of the pile head of the lower pile body is provided with the upper tooth-shaped joints, the upper tooth-shaped joints are fixedly connected with the upper pile body, and the lower tooth-shaped joints are meshed with and fixedly connected with the upper tooth-shaped joints. The square pile with the tooth-shaped joints can greatly increase the weld length and is easy to align.

Description

A kind of square pile of dentation type joint
Technical field
The utility model relates to a kind of ground stabilization square pile in building field, specifically a kind of square pile of dentation type joint.
Background technology
As everyone knows, concrete prefabricated square pile is used widely because of advantages such as its steady quality, easy constructions.During piling, there will be because geological conditions is bad or reason such as stake long deficiency etc., cause pile top position not reach bearing stratum depth, just need to carry out pile extension in this case.Traditional artificial Jointing mode, because soldered is too level and smooth, in welding process, two are easy to produce slippage, cause square pile contraposition inaccurate; Because weld seam overall length is shorter, the mechanical property of square pile joint is also difficult to guarantee completely, and then has influence on the quality of whole construction works simultaneously.
Utility model content
For above problem, the utility model provides the square pile that can increase considerably fusion length and be easy to a kind of dentation type joint of contraposition.
In order to realize the purpose of this utility model, the utility model provides a kind of square pile of dentation type joint.
A kind of square pile of dentation type joint, comprise upper piles and lower piles, the pile crown surrounding of described upper stake is provided with dentation lower contact, and dentation lower contact is fixedly connected with upper stake pile body, the described pile crown surrounding of lower is provided with dentation top connection, and dentation top connection is fixedly connected with a lower pile body, described dentation lower contact and dentation top connection are meshed and are fixedly linked.
Described dentation lower contact and dentation top connection are ferrous materials.
Reinforcing bar in described dentation lower contact and upper stake is weldingly connected, and the reinforcing bar in described dentation top connection and lower is weldingly connected.
Between described dentation lower contact and dentation top connection, be fixedly connected by welding.
The tooth length of described dentation lower contact is not less than 1/8 of the stake pile body cross section length of side, and the tooth length of dentation top connection is not less than 1/8 of lower the pile body cross section length of side.
The utility model also comprises damper, and described damper is fixed on pile head or lower pile head is inner.
beneficial effect
1, the utility model is not changing on the basis of existing system stake and construction technology, adopts the square pile of dentation type joint to increase substantially pile extension quality, obviously improves the mechanical properties such as tension, shearing resistance at pile extension position.
2, the utility model easy construction, energy automatic aligning, adopts dentation type joint greatly to increase fusion length, can improve bonding strength more than 30%.
3, dentation type joint employing welding manner of the present utility model is fixing more can strengthen bonding strength than using the component such as bolt to fix.
4, in the utility model because square pile belongs to slim-lined construction, the ability of opposing horizontal earthquake shearing and twisting resistance is poor, in upper stake or lower pile head position, damper is set, and can effectively resist the twisting resistance that earthquake puts on stake.
5, in the utility model, the tooth length of dentation lower contact is not less than 1/8 of the stake pile body cross section length of side, and the tooth length of dentation top connection is not less than 1/8 of lower the pile body cross section length of side and can improves and be welded to connect intensity.

The specific embodiment
Below in conjunction with Figure of description, the utility model will be further described.
Embodiment
As shown in Figure 1 to Figure 3
A kind of square pile of dentation type joint, comprise stake 1 and lower 2, the pile crown surrounding of described upper stake 1 is provided with dentation lower contact 3, and dentation lower contact 3 is fixedly connected with upper stake pile body, the described pile crown surrounding of lower 2 is provided with dentation top connection 4, and dentation top connection 4 is fixedly connected with a lower pile body, described dentation lower contact 3 and dentation top connection 4 are meshed and are fixedly linked.
Described dentation lower contact 3 and dentation top connection 4 are ferrous materials.
Described dentation lower contact 3 is weldingly connected with the reinforcing bar in upper stake 1, and described dentation top connection 4 is weldingly connected with the reinforcing bar in lower 2.
Between described dentation lower contact 3 and dentation top connection 4, be fixedly connected by welding.
The tooth length of described dentation lower contact 3 is not less than 1/8 of stake 1 length of side, and the tooth length of dentation top connection 4 is not less than 1/8 of lower 2 length of sides.
In square pile, also comprise damper 5, described damper 5 is fixed on stake 1 pile crown or lower 2 pile crowns are inner.
During operation, first adjust the position of upper stake, the axis of stake and the axis of lower are coincided as far as possible, in adjustment, stake slowly moves to the position that contacts, and when upper piles and lower piles fasten, illustrates that preformed pile connecting completes, and welds subsequently.
