Abstract
A kind of modified hollow square pile, it comprises first segment prefabricated tubular pile (1) and second section prefabricated tubular pile (2), described first segment prefabricated tubular pile (1) is positioned at immediately below described second section prefabricated tubular pile (2), described first segment prefabricated tubular pile (1) is longitudinally welded with two pieces of hollow little steel pipes (3), reinforcing cage (4) is positioned at described first segment prefabricated tubular pile (1) and the inside of second section prefabricated tubular pile (2), the bottom of described reinforcing cage (4) is provided with supporting plate (5), described first segment prefabricated tubular pile (1) has reinforcing bar pin (6) with the weld of second section prefabricated tubular pile (2), described reinforcing bar pin (6) is positioned on described hollow little steel pipe (3), described the first prefabricated tubular pile (1) is welded together by weldment (7) with the second prefabricated tubular pile (2) weld outside, which overcome existing joint and there is the shortcoming of durability and overall employing fixed point gate spool pile joint waste concrete, it has the advantage that ensure that joint intensity He provide pile tube bearing capacity.
Description
Technical field
The utility model relates to square pile technical field, more specifically a kind of modified hollow square pile.
Background technology
Hollow square pile and pile tube are a kind of comparatively economic pile-type.At present, the connection between stake and stake, adopting in construction is traditional welding or mechanical connection comparatively widely.Because welding quality man's activity is comparatively large, welding point place corrosion resistance is poor.Especially, when considering that resistance to plucking uses, uplift resistance imports lower joint stake (first segment prefabricated tubular pile) into mainly through weld, and often joint determines the uplift resistance of whole pile.
In engineering normal in order to reinforcing joint by the whole pouring reinforcement concrete of whole pile core, a large amount of steel concrete wastes can be caused; Just because of joint exists endurance issues, some areas are even put into effect and are provided against pile tube or hollow square pile for resistance to plucking.
Therefore, research and develop a kind of requirement that both can reach uplift resistance, the modified hollow square pile saving again Reinforced Concrete Materials becomes a urgent and important job.
Summary of the invention
The purpose of this utility model is the deficiency overcoming above-mentioned background technology, and proposes a kind of modified hollow square pile.
A kind of modified hollow square pile of the utility model.It comprises first segment prefabricated tubular pile and second section prefabricated tubular pile, described first segment prefabricated tubular pile is positioned at immediately below described second section prefabricated tubular pile, described first segment prefabricated tubular pile is longitudinally welded with two pieces of hollow little steel pipes, reinforcing cage is positioned at described first segment prefabricated tubular pile and the inside of second section prefabricated tubular pile, the bottom of described reinforcing cage is provided with supporting plate, described first segment prefabricated tubular pile and the weld of second section prefabricated tubular pile have reinforcing bar pin, described reinforcing bar pin is positioned on described hollow little steel pipe, be fixed together by weldment between the first described prefabricated tubular pile and the second prefabricated tubular pile.
In technique scheme: have foamed glue in described two pieces hollow little steel pipes.
The utility model tool has the following advantages: 1. because the link of pile tube or hollow square pile weakness is in joint, by the joint fixed point concreting core to pile tube or hollow square pile, thus strengthens the durability of joint, ensure that the intensity of joint; 2. improve the bearing capacity especially uplift resistance of pile tube or hollow square pile.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the concrete detail drawing at the utility model A place.
In figure: first segment prefabricated tubular pile 1, second section prefabricated tubular pile 2, hollow little steel pipe 3, reinforcing cage 4, supporting plate 5, reinforcing bar pin 6, weldment 7.
Detailed description of the invention
Illustrate below in conjunction with accompanying drawing and describe performance of the present utility model in detail, but they do not form restriction of the present utility model, only for example.Illustrate that advantage of the present utility model will become clearly and easy understand by this simultaneously.
Known with reference to accompanying drawing: a kind of modified hollow square pile of the utility model, it is characterized in that: it comprises first segment prefabricated tubular pile 1 and second section prefabricated tubular pile 2, described first segment prefabricated tubular pile 1 is positioned at immediately below described second section prefabricated tubular pile 2, described first segment prefabricated tubular pile 1 is longitudinally welded with two pieces of hollow little steel pipes 3, reinforcing cage 4 is positioned at described first segment prefabricated tubular pile 1 and the inside of second section prefabricated tubular pile 2, the bottom of described reinforcing cage 4 is provided with supporting plate 5, described first segment prefabricated tubular pile 1 has reinforcing bar pin 6 with the weld of second section prefabricated tubular pile 2, described reinforcing bar pin 6 is positioned on described hollow little steel pipe 3, the first described prefabricated tubular pile 1 and the second prefabricated tubular pile 2 weld outside are welded together by weldment 7, the first described prefabricated tubular pile 1 and the second prefabricated tubular pile 2 internal material are foamed glue (as Fig. 1).
Technological principle of the present utility model: when producing pile tube, weld separately two pieces of hollow little steel pipes 3 at first segment prefabricated tubular pile 1 end plate place.In first segment prefabricated tubular pile 1, filled and process rubber seal carries out the production of normal pile tube or hollow square pile after closing.
When constructing, normally squeeze into first segment prefabricated tubular pile 1, the reinforcing cage 4 (back cover) of certain length is put into the first prefabricated tubular pile 1, reinforcing cage 4 is fixed on the hollow little steel pipe 3 buried underground in pile tube by inserting a reinforcing bar pin 6, then is inserted in second section prefabricated tubular pile 2 by normal construction operation.Outside carries out welding or being mechanically connected.When first segment prefabricated tubular pile 1 dozen is to ground, according to the length of reinforcing cage in stake 4, the side's of calculating amount is directly by stake apical pore button concreting.Continue after building to construct routinely.
Because the link of pile tube or hollow square pile weakness is in joint, by the joint fixed point concreting core to pile tube or hollow square pile, thus strengthens the durability of joint, ensure that the intensity of joint.Provide the bearing capacity especially uplift resistance of pile tube or hollow square pile.
Other unspecified part is prior art.
