Abstract
An end plate for inter-pile purely-mechanical connection comprises a plate body (1), and is characterized in that transverse or longitudinal connectors (2) are welded on the plate body (1), two ends of each connector (2) are respectively provided with internal threaded holes for screwing in pile-connecting bolts. The end plate is quick and convenient to connect and high in quality, and pressure resistance and uplift resistance are improved evidently.
Description
Technical field
The utility model relates to a kind of connection of concrete pile and uses accessory, is connected the end plate of usefulness between the demanding stake of especially a kind of resistance to compression and extraction-resistant behavior and the stake, specifically a kind of and between pure mechanical connection use end plate.
Background technology
As everyone knows, preformed pile is the maximum pile foundation material of present use amount, and it comprises Pretensioned spun concrete piles, pretensioning prestressed concrete hollow square pile, the solid side's stake of pretensioning prestressed concrete, prefabricated solid side's stake.At present, above-mentioned pile foundation material has changed the preparation method of cast in situs in the past when producing, adopt the guaranteed factory floor streamline of quality production technology more.
Concrete pile is the very big slender member of a kind of draw ratio.End plate is often used at two ends during making, and main purpose has: one, when making prestressed pile, make whole, the average stretch-draw of whole all tendons of pile; Two, strengthen the intensity of stake end, make it in work progress, can bear bigger pressure; Use when three, stake and stake are welded to connect.
In the pile foundation construction process, between stake and the stake to be connected be an important construction technology, this technology influences bigger to the resistance to compression of single pile resistance to plucking and pile foundation.At present, this connected mode mainly is to connect through welded end plate at the construction field (site), can also weld with the angle steel reinforcement at four angles of stake for precast square pile, strengthens the reliability that stake and stake are connected.But the defective of these methods also is that significantly mainly contain: 1, the construction technology quality is wayward, and the quality of welding is difficult to carry out mechanics and detects; 2, the site operation uncertainty is more, constructional difficulties, and labor strength is big, and welding quality is difficult for guaranteeing.
Summary of the invention
The purpose of the utility model is to mainly low through the bonding strength that is welded to connect existence between existing stake and the stake; Labour intensity is big; The problem of difficult quality control; A kind of pure mechanical connection of utility model, need not weld job can satisfy instructions for use the stake with between pure mechanical connection use end plate.
The technical scheme of the utility model is:
Pure mechanical connection is used end plate between a kind of stake and the stake, and it comprises plate body 1, it is characterized in that being welded with on the described plate body 1 connector 2 that traverses or pass through, and the two ends of described connector 2 respectively are processed with an internal thread hole 3 that supplies the pile extension bolt to screw in.
Described connector 2 is cross, groined type or parallel lines and arranges.
Described connector 2 is the steel of other structures such as round steel structure or steel plate.
Described plate body 1 is side's plate with holes, side's plate not with holes or the plectane with holes that matches with pile body, and the hole of described side's plate with holes or plectane with holes is unthreaded hole or screw.
The beneficial effect of the utility model:
1, the utility model help strengthening stake with between the quality that is connected.
2, the utility model helps reducing working strength of workers, improves workman's efficiency, improves workman's labor safety coefficient.
3, the utility model can make stake quicker with being connected of stake so that the piling extraction-resistant behavior significantly improves, more stable quality, reliable.
Description of drawings
Fig. 1 is the structural representation of existing end plate.Its face shaping can be various forms, can be hollowcore slab (a) like Fig. 1; Also can be solid slab (like Fig. 1 b); Can be square, also can be circular (like figure c).
Fig. 2 is the structural representation of the utility model.
Fig. 3 is the user mode schematic perspective view of the utility model on hollow square pile.
Fig. 4 is the user mode schematic perspective view of the utility model on the circular hollow pile tube.
The specific embodiment
Below in conjunction with accompanying drawing and embodiment the utility model is further described.
As shown in Figure 2.
Pure mechanical connection is used end plate between a kind of stake and the stake, and it comprises plate body 1, is welded with the connector 2 that traverses or pass through on the described plate body 1; The length of connector 2 should and the boundary line on the relative both sides of end plate between length be complementary; An operation requirement of mould in the time of should guaranteeing to cast, for side's stake, the length and the length of side of connector 2 are complementary; For the pipe stake, the length of connector 2 can be the chord length that diameter or length are not less than diameter 3/4.The two ends of described connector 2 respectively are processed with an internal thread hole 3 that supplies the pile extension bolt to screw in, and this screwed hole 3 is used the obstruction that can take off and blocked when the system stake, block and can't use to prevent that concrete from getting into.Described connector 2 is cross, groined type or parallel lines and arranges.Described connector 2 is the steel of other structures such as round steel structure or steel plate, and described plate body 1 is side's plate with holes, side's plate not with holes or the plectane with holes that matches with pile body, and the hole of described side's plate with holes or plectane with holes is unthreaded hole or screw.
Fig. 3, the 4th, the utility model multi-form the syndeton sketch map of end plate, it also be final stake with between the syndeton sketch map.
The utility model does not relate to all identical with the prior art prior art that maybe can adopt of part to be realized.
