In order to solve the problems of the technologies described above, the technical scheme that the utility model adopts is to provide precast concrete cross pile, comprise pile body, in described pile body, be provided with many reinforcing bar keel, the cross section of described pile body is " cross " type, protuberance forms 4 fins, and 4 described fins arrange along the length direction of described pile body, and the bottom of described pile body is provided with and imports end.

In technique scheme, 4 described fins are arranged symmetrically with the central axis of described pile body.

In technique scheme, the width of 4 described fins is all identical, is 1/3 of described pile body overall width.

In technique scheme, the width of 4 described fins is identical, is 1/2 of described pile body overall width.

In technique scheme, the bottom of described fin is inclined-plane, forms described importing end.

In technique scheme, many described reinforcing bar keel are located at respectively the inside of the fin of described pile body.

In technique scheme, many described reinforcing bar keel one end are positioned at described importing end, and the other end passes the end face of described pile body.

In technique scheme, described reinforcing bar keel are provided with reinforcing cage.

In technique scheme, be provided with multiple stirrups in the inside on the top of described pile body, the two ends of every two described stirrups are separately fixed on described reinforcing bar keel and form cross, and arrange along the length direction interval of pile body.

In technique scheme, the length of described pile body is 4-9m.

Precast concrete cross pile of the present utility model adopts " cross " type structure, and be provided with import end, saved material, high, the prefabricated convenience of bearing capacity, construct fast, improved economic benefit, the precast concrete cross pile of different length has facilitated piling construction simultaneously.

Detailed description of the invention

Below in conjunction with accompanying drawing, the utility model is described in detail.

Referring to figs. 1 through Fig. 4, as shown in Figure 1, precast concrete cross pile 100 of the present utility model comprises pile body 110, imports end 120 and reinforcing bar keel 130, and reinforcing bar keel 130 are located at the inside of pile body 110, and importing end 120 is positioned at the bottom of pile body 110.

As shown in Figure 2, the quantity of reinforcing bar keel 130 is many, is fixed with reinforcing cage 132 and stirrup 134 on reinforcing bar keel 130.Reinforcing bar keel 130 are fixed together by stirrup 134.

The first embodiment as shown in Figure 3,4 fins 140 are arranged symmetrically with the central axis of pile body 110, and the width of 4 fins 140 is all identical, is 1/3 of pile body 110 overall widths.

The second embodiment as shown in Figure 4, the width of 4 fins 140 is all identical, is 1/2 of pile body 110 overall widths.The width of middle fin 140 is 1/2 of pile body 110 overall widths.

Under same circumference, adopt the precast concrete cross pile 100 of symmetrical " cross " type to save the area of section, reduced the use amount to concrete and reinforcing bar simultaneously, small investment, has reached and has saved the object of producing material.

The bottom of fin 140 is inclined-plane, forms and imports end 120.Introduction segment 120 can be also " wedge shape ", and two inclined-planes of " wedge shape " lay respectively at the upper of relative fin 140.The existence that imports end 120 makes the easier ground the inside that is driven into of precast concrete cross pile 100, drives piles also more convenient.

The quantity of reinforcing bar keel 130 is many, and many reinforcing bar keel 130 are separately fixed at the inside of fin 140 on pile body 110.One end of reinforcing bar keel 130 is positioned at and imports end 120, and the other end passes the end face of pile body 110.Many reinforcing bar keel 130 have strengthened the longitudinal load-bearing power of precast concrete cross pile 100, have also increased the structural strength of precast concrete cross pile 100.Simultaneously reinforcing bar keel 130 pass the end face of pile body 110, have also facilitated being connected of extraneous building and precast concrete cross pile 100.

As shown in Figure 5, be provided with reinforcing cage 132 in pile body 110, reinforcing cage 132 is fixed on reinforcing bar keel 130, has effectively strengthened the bearing capacity of precast concrete cross pile 100.

As shown in Figure 3, Figure 4, inside on the top of precast concrete cross pile 100 is provided with multiple stirrups 134, the two ends of every two stirrups 134 are separately fixed on reinforcing bar keel 130 and form cross, and multiple criss-cross stirrup 134 structures are arranged along the length direction interval of pile body 110, have effectively been strengthened the stability of precast concrete cross pile 100 junctions.

The length of pile body 110 is 4-9m, can customize according to different engineerings, have stake compared with short, section is little, from the feature of heavy and light." cross " type section is straight line, and formwork erection is convenient, and precast concrete cross pile 100 can, at factory's Prefabrication in batches, be also extremely suitable for building-site prefabricated, and carry very convenient.

The utility model is not limited to above-mentioned preferred forms, and anyone should learn the structural change of making under enlightenment of the present utility model, every with the utlity model has identical or close technical scheme, within all falling into protection domain of the present utility model.
