The utility model has the advantages of bearing capacity is high, construction convenience.
Description
Technical field
This utility model relates to the technical field of civil engineering, particularly relates to the precast concrete pile of industry and civil buildings, specifically, is a kind of jointing being applicable to square prefabricated concrete stake.
Background technology
Long precast concrete pile segmentation is manufactured, and carrying out joint connection in site in use has many advantages, and the danger the most easily transport, being damaged in transportation is little and freight is relatively low etc..But, use the problem that stub must solve securely each section of stub to be linked together.
Common precast concrete pile connects has welding and sulphide mastic to be anchored method both approaches.Sulphide mastic be anchored method pile extension be only applicable to that seismic fortification intensity is less than the engineering pile foundation of 7 degree and the softest in soil property, estimation pile sinking with no difficulty in the case of the most preferably use.When there being the pile foundation engineering of requirements for fortification against earthquake, for the highest stake of single pile design bearing capacity, it has to pass through thicker hard soil layer and the stake that is in large stretch of intensive pile group uses welding more.
The general about 20min of each welding point is soldered, and after weld seam natural cooling 8min, could continue injection or piling.Owing to the pile extension technology elapsed time of tradition welding is too much, and quality is affected by factors such as welding quality of workers, construction method, environment, is easier to the weld defects such as pore, slag inclusion, crackle and undercut occur, and these defects will directly affect weld strength.Being primarily subjected to shearing after squeezing into the soil body due to pile tube, weld strength is unsatisfactory for requirement, and welding seam breaking, upper and lower two pile bodies seriously can be caused to separate, and the bearing capacity of stake cannot meet the consequences such as design requirement.
In a word, current precast concrete pile jointing there is also low bearing capacity, and construction environment requires height, the problems such as difficulty of construction is big.Research and development can bear moment of flexure, shearing and pulling force and centering is good, speed of application is fast, steady quality, flames of anger operation, do not affected by construction environment and weather, the jointing of all-weather construction important engineer applied can be had to be worth.
Utility model content
Technical problem to be solved in the utility model is for the above-mentioned state of the art, and provides a kind of bearing capacity high, the precast concrete square pile jointing of easy construction.
The technical scheme that the above-mentioned technical problem of this utility model solution is used is:
A kind of precast concrete square pile jointing, wherein: include the joint end plate being arranged on precast concrete square pile end, four limits of joint end plate are each formed with embedded draw-in groove, jointing also includes buckle, buckle can snap in the embedded draw-in groove of two precast concrete square piles docked mutually simultaneously, makes two precast concrete square piles fix.
For optimizing technique scheme, the concrete measure taked also includes:
Extend to the outer surface direction of joint end plate to be formed inside above-mentioned embedded draw-in groove and buckle the end, embedded draw-in groove forms buckle shoulder outside the button end, buckle is C-shaped card, at the bottom of the button of the embedded draw-in groove that two precast concrete square piles docked mutually are inserted at the two ends of buckle respectively, buckle shoulder blocks the two ends of buckle makes buckle to exit.
The edge-smoothing transition of above-mentioned embedded draw-in groove, the edge, stage casing of buckle is provided with the acute angle suitable with embedded draw-in groove smooth edges, after buckle snaps in embedded draw-in groove, the embedded draw-in groove of acute angle filling-in seamlessly transit angle.
Above-mentioned joint end plate and buckle are steel design.
The bottom of above-mentioned embedded draw-in groove extends transversely through precast concrete square pile pile body, with the inner space of precast concrete square pile.
Above-mentioned embedded draw-in groove extends to, from the one side of joint end plate, the one side that joint end plate is adjacent.
Compared with prior art, a kind of precast concrete square pile jointing of the present utility model, can effectively fix two sections of precast concrete square piles, four limits of the joint end plate of this your utility model are each formed with embedded draw-in groove, and buckle snaps in draw-in groove fixing, and two square piles being connected can be made to obtain very firm shearing resistance, and arranging of buckle and draw-in groove is simple, construction extremely convenient, saves the plenty of time than welding, is suitable for large-scale use on building site.

Detailed description of the invention
Below in conjunction with accompanying drawing, embodiment of the present utility model is described in further detail.
As shown in Figures 1 to 5, a kind of precast concrete square pile jointing of the present utility model, including the joint end plate 1 being arranged on precast concrete square pile end, four limits of joint end plate 1 are each formed with embedded draw-in groove 11, jointing also includes buckle 2, buckle 2 can snap in the embedded draw-in groove 11 of two precast concrete square piles docked mutually simultaneously, makes two precast concrete square piles fix.
In embodiment, the internal formation to the extension of the outer surface direction of joint end plate 1 of embedded draw-in groove 11 buckles the end 12, embedded draw-in groove 11 forms buckle shoulder 13 outside the button end 12, buckle 2 is C-shaped card, at the bottom of the button of the embedded draw-in groove 11 that two precast concrete square piles docked mutually are inserted at the two ends of buckle 2 respectively 12, buckle shoulder 13 blocks the two ends of buckle 2 makes buckle 2 to exit.
In embodiment, the edge-smoothing transition of embedded draw-in groove 11, the edge, stage casing of buckle 2 is provided with the acute angle 21 suitable with embedded draw-in groove 11 smooth edges, after buckle 2 snaps in embedded draw-in groove 11, the embedded draw-in groove of acute angle 21 filling-in 11 seamlessly transit angle.
In embodiment, joint end plate 1 and buckle 2 are steel design.
In embodiment, embedded draw-in groove 11 extends to, from the one side of joint end plate 1, the one side that joint end plate 1 is adjacent.
Using method of the present utility model is as follows: long precast concrete pile segmentation manufactured, at each stub two ends anchor tip end plate 1, by two stub two ends docking in work progress, then buckle 2 is used to buckle in the embedded draw-in groove 11 of joint end plate 1, embedded draw-in groove 11 is distributed on four limits of square pile, each embedded draw-in groove 11 is intended to buckle into buckle 2, makes square pile interface can resist the shearing from all directions.
