Abstract
The utility model provides a lath type connector connecting solid square pile. The square pile comprises an upper segment pile, a lower segment pile, an upper segment pile steel cap, a lower segment pile steel cap and steel laths. The upper segment pile steel cap and the lower segment pile steel cap are formed by steel plate connection, are connected with main ribs of both the upper segment pile and the lower segment pile and are pre-embedded at the top of the square pile. The upper segment pile steel cap and the lower segment pile steel cap are in butt joint through a plurality of steel laths, and the lath type connector connecting solid square pile is formed. The lath type connector connecting solid square pile has the advantages of overcoming the shortcomings of being difficult to weld, not firm to weld and easy to deform and the like in comparison with conventional angle steel welding, being simple and convenient to weld, improving pull-resistant capability by over 30%, improving working efficiency by over 30%, reducing potential safety hazards of foundation engineering and further guaranteeing safety of structures. The lath type connector connecting solid square pile is simple and convenient in connecting mode, improves working efficiency by over 20%, reduces the potential safety hazards of foundation engineering, and further guarantees safety of the structures.
Description
Technical field
The utility model relates to a kind of precast square pile syndeton, and particularly a kind of strip type joint connects solid square pile.
Background technology
Piling as the foundation pile engineering has pile tube, all kinds of square pile, castinplace pile, drilled pile etc.In work progress, all to prove the length of foundation pile according to the ground situation.Thereafter, in a planned way to successively welding of some concrete joint stake enforcements.Therefore, the joint construction of welding how between joint stake, and how its quality can directly affect the indices 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 welding four bights of pile body between the pile cover of joint stake two ends by angle steel is generally adopted in the connection of concrete square pile section stake.This type of attachment is difficult for welding, and not prison welding is solid, welding is yielding, causes a little less than the whole stake of welded construction bending resistance, resistance to plucking, the shear resistance.Simultaneously, during welding since pile cover from concrete very close to, electric welding heat can cause serious internal construction infringement to pile crown position concrete.The detection operation of in addition, returning the detection tabs quality by the angle steel welded construction between the steel cap brings difficulty.Design a kind of rational in infrastructurely, easily welding can not injure pile body in the welding, is convenient to the pile joint structure that the every quality index of soldered detects after the welding, has put an important topic the pile foundation those skilled in the art.
Summary of the invention
For structural deficiency in the prior art, the purpose of this utility model provides a kind of strip type joint and connects solid square pile, the shortcomings such as difficult welding, not prison welding is solid, welding is yielding have been avoided with conventional angle steel welding, make welding simple and easy, convenient, improve a resistance to plucking ability more than 30%, increase work efficiency more than 30%, reduce the potential safety hazard of Foundation Design, further guaranteed the safety of structure.
For achieving the above object, the technical solution adopted in the utility model provides a kind of strip type joint and connects solid square pile, wherein: this square pile includes joint stake, the stake of lower joint, upper joint stake steel cap, lower joint stake steel cap and steel plate bar, described upper joint stake steel cap is that the steel plate connection is made with lower joint stake steel cap, main muscle with described upper joint stake, lower joint stake is connected respectively, and be embedded in advance square pile stake top, described upper joint stake steel cap and lower joint stake steel cap form the strip type joint and connect solid square pile by many steel plate bar docking.
The described upper longitudinal centre line that saves a steel cap and the docking of lower joint stake steel cap saves the outline misalignment＜5mm of stake under the described upper joint stake on same axis.
Effect of the present utility model is to have avoided the shortcomings such as difficult welding, not prison welding be solid, yielding with the welding of conventional angle steel, weld simple and easy, convenient, improve the resistance to plucking ability more than 30%, increase work efficiency more than 30%, reduce the potential safety hazard of Foundation Design, further guaranteed 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 the utility model strip type joint connects the solid square pile structural representation;
Fig. 2 is the A-A schematic cross-section of Fig. 1.
Among the figure:
1, upper joint stake 2, lower joint stake 3, upper joint stake steel cap 4, lower joint stake steel cap 5, steel plate bar
The specific embodiment
Reaching by reference to the accompanying drawings embodiment is illustrated strip type joint connection solid square pile structure of the present utility model.
As shown in Figure 1, strip type joint of the present utility model connects solid square pile, this square pile includes joint stake 1, lower joint stake 2, upper joint stake steel cap 3, lower joint stake steel cap 4 and steel plate bar 5, described upper joint stake steel cap 3 be connected joint stake steel cap 4 to make for the steel plate connection, main muscle with described upper joint stake 1, lower joint stake 2 is connected respectively, and being embedded in advance square pile stake top, described upper joint stake steel cap 3 and lower joint stake steel cap 4 form the strip type joint and connect solid square pile by 5 docking of many steel plate bars.
The longitudinal centre line of described upper joint stake steel cap 3 and 4 docking of lower joint stake steel cap on same axis, the outline misalignment＜5mm of described upper joint stake 1, lower joint stake 2.
As shown in Figure 2, take stake type 350*350 as example, upper joint stake steel cap 3 and lower joint stake steel cap 4 all are to form with Plate Welding, and 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 up and down joint stake that fixes totally 8 uniformly.
Adopt the utility model strip type joint to connect the solid square pile structure, 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.
