Abstract
The invention provides a slat type connector connecting solid square pile which comprises an upper pile section, a lower pile section, an upper pile section steel cap, a lower pile section steel cap and steel slats. The upper pile section steel cap and the lower pile section steel cap are formed by connection of steel plates, are connected with main ribs of the lower pile section and the upper pile section respectively and are pre-embedded at the top of the square pile, and the upper pile section steel cap and the lower pile section steel cap are in butt joint through a plurality of steel slats, so that the slat type connector connecting solid square pile is formed. The slat type connector connecting solid square pile overcomes the shortcomings of difficulty in welding, instability in welding and easiness in deformation and the like in comparison with conventional angle steel welding, is simple and convenient to weld, improves pulling-resistant capability by over 30%, improves working efficiency by over 30%, reduces potential safety hazards of foundation engineering and further guarantees safety of structures. A connecting method is simple and convenient, the working efficiency is improved by over 20%, the potential safety hazards of foundation engineering are reduced, and the safety of the structures is further guaranteed.
Description
Technical field
The present invention relates to a kind of precast square pile syndeton, particularly a kind of strip type joint connects solid side's stake.
Background technology
Piling as the foundation pile engineering has pile tube, all kinds of side stake, castinplace pile, drilled pile etc.In work progress, all to prove the length of foundation pile based on the ground situation.Thereafter, in a planned way to some concrete joint stake enforcements welding successively.Therefore, the joint construction of welding how between joint stake, and how its quality can directly influence each item index performances such as the bearing capacity, bending resistance, resistance to plucking, shearing resistance of foundation pile.So the concrete pile joint quality is an important ring of whole quality of pile, also is the important component part of Antiseismic building, the case of collapsing of building has obtained enough checkings both at home and abroad, is paid close attention to by professional domain.
At present, the form of passing through four bights of angle steel welding pile body between the pile cover of joint stake two ends is generally adopted in the connection of concrete square pile joint stake.This type of attachment is difficult for welding, weld insecure, welding is yielding, cause a little less than whole bending resistance of welded construction, resistance to plucking, the shear resistance.Simultaneously, because pile cover is very near from concrete, electric welding heat can cause serious internal construction infringement to pile crown position concrete during welding.The detecting operation of in addition, returning the detection tabs quality through the angle steel welded construction between the steel cap brings difficulty.Design a kind of rational in infrastructurely, be prone to welding, can not injure pile body in the welding, be convenient to the pile joint structure that soldered each item quality index detects after the welding, put a important topic the pile foundation those skilled in the art.
Summary of the invention
To structural deficiency in the prior art; The purpose of this invention is to provide a kind of strip type joint and connect solid side's stake; Avoided shortcomings such as difficult welding, welding is insecure, welding is yielding, made that welding is simple and easy, convenient, a raising resistance to plucking ability is more than 30%, increased work efficiency more than 30% with conventional angle steel welding; Reduce the potential safety hazard of Foundation Design, further guaranteed the safety of structure.
For realizing above-mentioned purpose; The technical scheme that the present invention adopts provides a kind of strip type joint and connects solid side's stake; Wherein: this side stake includes stake joint, following joint, goes up a joint steel cap, a following steel cap and the steel plate bar of saving; Said joint stake steel cap and the joint stake steel cap down gone up is that steel plate is connected and processes, respectively with saidly go up the stake joint, following main muscle that saves is connected, and push up a pre-buried side of being located at; The said joint steel cap of going up passes through many steel plate bars butt joints with following joint stake steel cap, and formation strip type joint connects solid side's stake.
The said longitudinal centre line of going up joint stake steel cap and joint stake steel cap butt joint down on same axis, said following the outline misalignment < 5mm who saves of stake joint that go up.
Effect of the present invention is to have avoided difficult welding, welded shortcomings such as insecure, yielding with conventional angle steel welding; Weld simple and easy, convenient, improve the resistance to plucking ability more than 30%; Increase work efficiency more than 30%, reduced the potential safety hazard of Foundation Design, further guarantee the safety of structure.Connected mode is simple and easy, convenient, increase work efficiency more than 20%, reduced the potential safety hazard of Foundation Design, further guarantees the safety of structure.
Description of drawings
Fig. 1 is that strip type joint of the present invention connects solid side's pilework sketch map;
Fig. 2 is the A-A schematic cross-section of Fig. 1.
Among the figure:
1, go up joint stake 2, joint stake 3 down, go up a joint stake steel cap 4, a joint stake steel cap 5, steel plate bar down
The specific embodiment
Reaching embodiment in conjunction with the accompanying drawings connects solid side's pilework to strip type joint of the present invention and illustrates.
As shown in Figure 1; Strip type joint of the present invention connects solid side stake, and this side stake includes stake joint 1, following joint 2, goes up a joint stake steel cap 3, joint stake steel cap 4 and steel plate bar 5 down, and said going up saved a steel cap 3 and processed for steel plate is connected with a following steel cap 4 that saves; Be connected with the said main muscle of going up stake joint 1, following joint 2 respectively; And stake stake top, the pre-buried side of being located at, said joint stake steel cap 3 and the joint stake steel cap 4 down gone up be through 5 butt joints of many steel plate bars, forms the strip type joint and connect solid side.
The said longitudinal centre line of going up joint stake steel cap 3 and joint stake steel cap 4 butt joints down is on same axis, and the said stake joint 1, following gone up saves 2 outline misalignment < 5mm.
As shown in Figure 2, be example with stake type 350*350, last joint stake steel cap 3 all is to be welded with steel plate with a following joint stake steel cap 4, driving cap is welded on the main muscle, is embedded in the stake top.Steel plate bar 5 is of a size of 80mm*400mm*8, and two every quantity is welded on the four sides of pile cover of the joint stake up and down that fixes totally 8 uniformly.
Adopt strip type joint of the present invention to connect solid side's pilework, improved the resistance to plucking ability more than 30%, increase work efficiency more than 30%, reduced the potential safety hazard of Foundation Design, further guarantee the safety of structure.
