The specific embodiment
Understand for technical characterictic of the present utility model, purpose and effect being had more clearly, now contrast the description of drawings specific embodiment of the present utility model.Wherein, identical parts adopt identical label.
Describe structure and principle thereof with reference to the accompanying drawings in detail according to a kind of hollow concrete prestress square pile of the present utility model.
Fig. 1 is the reinforcement structure schematic diagram according to the hollow concrete prestress square pile of a specific embodiment of the present utility model; Fig. 2 is the vertical view of hollow concrete prestress square pile shown in Figure 1; Fig. 3 is the schematic cross-section of hollow concrete prestress square pile shown in Figure 1; Specifically, hollow concrete prestress square pile of the present utility model, comprise that cross section is square pile body, described pile body two ends respectively are connected with a metal end plate 3, described pile body comprises first reinforcing cage and second reinforcing cage of arranged concentric, described first reinforcing cage is positioned at the described second reinforcing cage inboard, fixedly connected with described metal end plate 3 respectively in the described first reinforcing cage two ends, described first reinforcing cage is first circular layout, described second reinforcing cage is second circular layout, and four angles of the cross section of described pile body are that stress is eliminated arc chord angle.
With the described metal end plate 3 that described first reinforcing cage is fixedlyed connected, make described hollow concrete prestress square pile can possess better impact resistance and much smaller pile crown breakage rate; Obtain bigger welding girth simultaneously,, make pile quality more excellent so the effective weld strength between every joint stake when fully having guaranteed pile extension has reduced described hollow concrete prestress square pile greatly and joint sealing-off or offset phenomena occur in construction.
Described pile body comprises first reinforcing cage and second reinforcing cage of arranged concentric, described first reinforcing cage is positioned at the described second reinforcing cage inboard, fixedly connected with described metal end plate 3 in the described first reinforcing cage two ends, also make the pile body of this hollow concrete prestress square pile can reduce or offset the tensile stress of the concrete 2 of the caused described pile body of load, thereby with the tension Stress Control of described pile body more among a small circle, can postpone thus concrete 2 the crack appearance and carry out, improve the cracking resistance and the rigidity of member.
Four angles of the cross section of described pile body are that stress is eliminated arc chord angle, so not only make the good looking appearance of this hollow concrete prestress square pile, and avoided too small because of the pile body corner of this hollow concrete prestress square pile, make pile body in hoisting process, steel wire be rubbed and the generation security incident that drops.
In a specific embodiment, described first reinforcing cage comprises a plurality of along the described pile body axially extended first main muscle 11 and first stirrup 12, and described first stirrup 12 shape in the shape of a spiral is welded on the described first main muscle 11; Described second reinforcing cage comprises a plurality of along the described pile body axially extended second main muscle 21 and second stirrup 22, and described second stirrup 22 shape in the shape of a spiral is welded on the described second main muscle 21, and the length of the described second main muscle 21 is than described first main muscle 11 weak points.
Described first stirrup 12 shape in the shape of a spiral is welded on the described first main muscle 11, being convenient to mechanization like this welds automatically, spiral helicine first stirrup 12 can make described first reinforcing cage possess good anti-flexible, torsional property simultaneously, same, described second stirrup 22 shape in the shape of a spiral is welded on and also can makes described second reinforcing cage possess good anti-flexible, torsional property on the described second main muscle 21; Therefore described first reinforcing cage and described second reinforcing cage also just can reduce the caused described pile body of load concrete 2 be subjected to flexure stress, thereby the flexure stress that is subjected to of pile body is controlled at more among a small circle, can postpone thus concrete 2 the crack appearance and carry out, improve the cracking resistance and the rigidity of member.
