Abstract
The utility model relates to a prestressing reinforced concrete pipe pile, the outer lateral surface of which is provided with friction grooves. The friction grooves are preferably arranged between projection lines of longitudinal reinforcing steel bars of the pipe pile toward the outer lateral surface of the pipe pile. The end parts of adjacent friction grooves are alternatively arranged. The friction grooves are additionally arranged on the side surface of the pipe pile to increase the surface friction force of the side surface. The friction force and the bearing capacity of the pipe pile arranged in the groundwork are increased through the action of transversal friction grooves, vertical friction grooves or obliquely straight or curved edge friction grooves which are distributed on the surface of the pipe pile, and meanwhile, the utility model has the advantages of material saving, and low cost.
Description
The utility model relates to a kind of stake that is used for building lot, particularly prestressed reinforced concrete pipe pile.
Prestressed reinforced concrete pipe pile of the prior art, its external surface smoother, in use, the frictional force of pile tube side surface is less, and frictional force is less to the bearing capacity of stake.
The purpose of this utility model is at the deficiencies in the prior art, and it is bigger to propose a kind of side surface frictional force, can increase the prestressed reinforced concrete pipe pile of the bearing capacity of stake.
The purpose of this utility model is reached by following technical scheme.The utility model is a kind of prestressed reinforced concrete pipe pile, is characterized in that the lateral surface of pile tube is provided with the friction groove.Like this, horizontal, the vertical or oblique straight flange by being distributed in stake surface or the effect of bent limit friction groove make that the frictional force of pile tube obtains increasing in the ground, have improved the bearing capacity of pile tube; Save material simultaneously, reduced cost.
Purpose of the present invention can also further reach by following measure.Aforesaid prestressed reinforced concrete pipe pile is characterized at the pile tube longitudinal reinforcement friction groove being set between the projection line of pile tube lateral surface.To guarantee concrete cover to reinforcement thickness, do not influence the cross section performance of stake.
Purpose of the present invention can also further reach by following measure.Aforesaid prestressed reinforced concrete pipe pile is characterized in that between the end of adjacent friction groove be to be staggered.To reduce the loss of same rigidity of section, increase pile tube and the native rubbing action that bonds.
The utility model has compared with prior art been set up the friction groove at the side surface of pile tube, and the skin friction of side surface is increased, and has improved the bearing capacity of pile tube.

Fig. 1, Fig. 2 embodiment of the present utility model.Contrast Fig. 1, Fig. 2 below, further describe implementer's case of the present utility model, Fig. 1, Fig. 2 are a kind of prestressed reinforced concrete pipe pile 3, and every longitudinal reinforcement 4 is provided with a vertical straight flange friction groove 2 between the projection line 1 of pile tube lateral surface in pile tube 3.The lateral cross section myopia of groove 2 is for trapezoidal.The rubbing action of the vertical straight flange friction groove 2 by being distributed in pile tube 3 surfaces improves frictional force and has made 10%, and the bearing capacity of pile tube 3 is strengthened, and has reduced cost.
Fig. 3, Fig. 4 another embodiment of the present utility model.Contrast Fig. 3, Fig. 4 below, another implementer's case of the present utility model is described, Fig. 3, Fig. 4 are another kind of prestressed reinforced concrete pipe pile 13, and every longitudinal reinforcement 14 is provided with two vertical straight flange friction grooves 12 between the projection line 11 of pile tube lateral surface in pile tube 13.Between the end of adjacent friction groove 12 is to be staggered.The lateral cross section of groove 12 is a del.By increasing pile tube 13 and native rubbing action.Frictional force has improved 15%, and the bearing capacity of pile tube 13 is strengthened, and this structure is convenient in demoulding when producing.
Fig. 5, Fig. 6 another embodiment of the present utility model.Contrast Fig. 5, Fig. 6 below, another implementer's case of the present utility model is described, Fig. 5, Fig. 6 are another kind of prestressed reinforced concrete pipe pile 23, and every longitudinal reinforcement 24 is provided with a vertical bent limit friction groove 22 between the projection line 21 of pile tube lateral surface in pile tube 23.Groove 22 is arcuate bottom.Like this, increased the bond rubbing action of pile tube 23 with soil, frictional force has improved 13%, and the bearing capacity of pile tube 23 is to strengthening.
