Description
Technical field
The utility model relates to a kind of construction technology of building pile foundation engineering, is specifically related to the syndeton of a kind of concrete pile and cushion cap.
Background technology
Along with the raising of the significance level of modern building and the continuous increase of building height, the supporting capacity of ground is had higher requirement.The concrete pile foundation of building construction in the past mainly bears the vertical compression load, but present many pile foundations then will be born vertical compression load and vertical tension load simultaneously.More existing in recent years engineerings require to reduce under the pressure promotion of construction costs the investor, and concrete pile is applied in the anti-floating engineering, use as uplift pile.Stake has been made clear and definite regulation with being connected of cushion cap when only concrete pile being made compressive pile or pressure bearing pile on prior art rules or the atlas, but does not make clear and definite regulation when the uplift pile yet for concrete pile.At present when stake top mark height is higher than design elevation, the method of attachment that is used for the concrete pile of resistance to plucking engineering and cushion cap mainly is to go into the core concrete of filling out that concrete that reinforcing cage waters certain volume simultaneously forms certain-length after the stake again toward stake interpolation chamber by with saw stake device pile body simply being cut, be connected with cushion cap and realize being connected of stake and cushion cap by filling out core concrete and stake bonding of inwall and reinforcing bar, realize that the basic while of preformed pile stake top and cushion cap is stressed.But there is more problem in this method, as: only dependence is filled out core concrete and is born uplift resistance, and job site environment more complicated even more abominable sometimes, can cause an inner cavity water accumulation serious, inwall mud can't be cleaned out, it is wayward that construction trouble causes filling out the core concrete construction quality, core concrete often occurs filling out and be pulled out and influence the resistance to plucking quality and cause engineering problem etc.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, and a kind of simple in structure, safe and reliable, convenient and quick construction, the concrete pile of saving construction costs and the syndeton of cushion cap are provided.
The technical solution of the utility model is: the syndeton of a kind of concrete pile and cushion cap, comprise concrete pile, foundation platform, the hole that is connected, end plate, reinforcing bar, reinforcing stirrup and reinforcing bar heading, the stake top of described concrete pile is connected with foundation platform, be provided with reinforcing bar in the described concrete pile pile body, the upper surface of concrete pile pile concrete is stretched out in the upper end of reinforcing bar, described end plate is installed in the reinforcing bar heading place of reinforcing bar, be provided with the reinforcing stirrup that is used for fixing end plate below the end plate, be evenly equipped with a plurality of holes that are connected that are used for connecting reinforcement on the end face of end plate.
As preferably, the described hole that is connected comprises stretching screw hole and heavy muscle hole, is provided with the muscle groove between described stretching screw hole and the heavy muscle hole, and described reinforcing bar inserts the stretching screw orifice ring and is connected after passing the muscle groove on the heavy muscle hole.
As preferably, when described concrete pile is hollow pile, the utility model syndeton also comprises reinforcing cage and fills out core concrete, described reinforcing cage is arranged in the cavity of concrete pile, reinforcing cage is made up of the thin steel supporting plate of vertical muscle (promptly filling out core concrete interpolation reinforcing bar), stirrup and circle, the thin steel supporting plate of circle is connected the bottom of vertical muscle, has built in the cavity of the concrete pile of the thin steel supporting plate of circle top and has filled out core concrete, and the end face of end plate is stretched out in the upper end of described vertical muscle.
As preferably, the described core concrete of filling out adopts slightly expanded concrete, and filling out core concrete intensity is C10 ~ C80, fills out core length and be pile tube stake footpath or side's stake length of side of 0.5 times pile tube stake footpath or the stake length of side ~ 20, side times, and fills out core length and be not less than 0.5m.
As preferably, the diameter of the thin steel supporting plate of described circle is less than or equal to the length of side of diameter or side's stake inner chamber of pile tube inner chamber, and the thin steel supporting plate thickness of circle is not less than 2mm.The length of described vertical muscle upper end is determined that by design hoop " ┐ " shape or vertical configuration outwardly is processed on vertical muscle top, and the quantity of vertical muscle is 4 ~ 30, and diameter is 6mm ~ 50mm, and the diameter of described stirrup is more than or equal to 3mm, and the spacing of stirrup is 40mm ~ 400mm.
The utility model structure is applicable to when concrete pile construction is finished stake top, a back actual elevation and is higher than design elevation, and scope comprises all concrete tubular piles and side, concrete precast pile and castinplace pile, concrete solid pile and hollow pile.
Job practices of the present utility model is: need cut stake when at first stake top actual elevation is higher than design elevation after construction is finished, cut the stake back and keep original reinforcing bar of pile body and end plate, the end plate of concrete pile is installed in the heading place of reinforcing bar, and with reinforcing stirrup with its fixed-site, realize being connected once more of end plate and reinforcing bar, the reinforcing cage that will be welded with the thin steel supporting plate of circle is then put in the inner chamber of concrete pile, pours into a mould slightly expanded concrete at last to the inner chamber of stake, forms reinforcing bar and fills out core concrete; Core concrete to be filled out is poured into a mould ordinary concrete to the cushion cap basis that is connected with stake after reaching certain intensity again, thus final the realization being connected of stake and cushion cap basis.
The beneficial effects of the utility model are: 1, guaranteed being connected between concrete pile and the cushion cap, and more safe and reliable.Abandon to only depend in the past and fill out core concrete and bear uplift resistance, adopt outside reinforcing bar to be connected once more and fill out the system that the interpolation reinforcing bar in the core concrete forms and bear uplift resistance jointly, make that the building foundation is stable more, safety with end plate.
2, simple in structure, save engineering comprehensive and cause.Do not waste pile body is cut reinforcing bar and end plate after the stake, and realize utilizing once more.
3, improved the concrete pile foundation construction quality, reduced the phenomenon that causes cushion cap to separate because of buoyancy is excessive, effectively avoided the generation of engineering safety accident, significantly reduced engineering safety hidden danger with stake.
4, applied widely.Applicable to the bigger more piece stake of anti-pulling capacity, also be applicable to the single-unit stake that uplift resistance is less.
