Abstract
The utility model discloses a kind of prefabricated reinforced concrete triangular foundation pile, comprise the pile body reinforcing bar of structure triangular in shape, described pile body reinforcing bar is fixed with the auxiliary muscle of triangular structure, the end points of described auxiliary muscle is separately fixed on the mid point on each limit of triangle of pile body reinforcing bar, described auxiliary muscle is fixed on described pile body reinforcing bar by muscle hoop, each angle of the triangular structure of described pile body reinforcing bar is provided with corner cut trimming, concrete perfusion in the space enclosed between described pile body reinforcing bar and auxiliary muscle.The advantage of technical solutions of the utility model is mainly reflected in: when stake cross-sectional area is identical, makes pile body girth maximum, thus the vertical ultimate bearing capacity of single pile standard value of friction pile and point friction pile under identical geological conditions is maximized; Reach the target of saving construction costs.Further, smart structural design, anti-shot ability is comparatively strong, and higher, the prestressed, reinforced process of intensity is easier.
Description
Technical field
The utility model relates to a kind of prefabricated reinforced concrete triangular foundation pile, belongs to construction engineering technical field.
Background technology
Along with the quickening of urbanization process, urban population is more and more intensive, and add the not reproducible of land resources, urban architecture is inevitably to Development of High-rise Buildings.In the process, foundation pile is widely used as a kind of common deep foundation form.The cost of foundation pile accounts for the proportion of whole construction costs very greatly, so selects to find the emphasis that a kind of suitable pile-type is Foundation Design cost control in other words, is necessary.
At present, widely used foundation pile in China's construction work, its cross section is mostly square and circular.Building expert is thought: the size of the bearing capacity of foundation pile and its surface area has direct relation.As everyone knows, leg-of-mutton girth is then far longer than square and circular girth.To this, people just think and change existing square and circular foundation pile into triangle, but caused by triangle foundation pile own form, anti-shot ability is poor, intensity is poor, prestressed, reinforced process is more difficult problem that it exists in test, brings many worries to every aspect for a long time.
Utility model content
The purpose of this utility model is exactly to solve the above-mentioned problems in the prior art, provides a kind of prefabricated reinforced concrete triangular foundation pile higher than Prefabricated Reinforced Concrete Square Pile vertical ultimate bearing capacity of single pile standard value under identical cost.
The purpose of this utility model is achieved through the following technical solutions:
A kind of prefabricated reinforced concrete triangular foundation pile, comprise the pile body reinforcing bar of structure triangular in shape, described pile body reinforcing bar is fixed with the auxiliary muscle of triangular structure, the end points of described auxiliary muscle is separately fixed on the mid point on each limit of triangle of pile body reinforcing bar, described auxiliary muscle is fixed on described pile body reinforcing bar by muscle hoop, each angle of the triangular structure of described pile body reinforcing bar is provided with corner cut trimming, concrete perfusion in the space enclosed between described pile body reinforcing bar and auxiliary muscle.
The advantage of technical solutions of the utility model is mainly reflected in: when stake cross-sectional area is identical, makes pile body girth maximum, thus the vertical ultimate bearing capacity of single pile standard value of friction pile and point friction pile under identical geological conditions is maximized; Reach the target of saving construction costs.Further, smart structural design, anti-shot ability is comparatively strong, and higher, the prestressed, reinforced process of intensity is easier.
Accompanying drawing explanation
Fig. 1 is the schematic cross-section of the foundation pile of prior art;
Fig. 2 is the schematic cross-section of foundation pile of the present utility model.
Detailed description of the invention
The purpose of this utility model, advantage and disadvantage, by for illustration and explanation for the non-limitative illustration passing through preferred embodiment below.These embodiments are only the prominent examples of application technical solutions of the utility model, allly take equivalent replacement or equivalent transformation and the technical scheme that formed, all drop within the claimed scope of the utility model.
A kind of prefabricated reinforced concrete triangular foundation pile that the present embodiment discloses, comprise the pile body reinforcing bar 2 of structure triangular in shape, described pile body reinforcing bar 2 is fixed with the auxiliary muscle of triangular structure, the end points of described auxiliary muscle is separately fixed on the mid point on each limit of triangle of pile body reinforcing bar 2, described auxiliary muscle is fixed on described pile body reinforcing bar 2 by muscle hoop, each angle of the triangular structure of described pile body reinforcing bar 2 is provided with corner cut trimming 4, concrete perfusion 3 in the space enclosed between described pile body reinforcing bar 2 and auxiliary muscle.
The vertical ultimate bearing capacity of single pile standard value of precast reinforced concrete pile can be calculated as follows:

By the vertical ultimate bearing capacity of single pile standard value Q of above formula visible friction pile and point friction pile under the same conditions
ukdepend on the size of pile body girth u, u is larger, Q
uklarger.Therefore the technical program is led to when stake cross-sectional area is certain, makes a section girth the longest, realizes in the maximum target of identical cost Single Pile ultimate vertical bearing capacity standard value with this.
Refer to Fig. 1 and Fig. 2, the utility model prefabricated reinforced concrete triangle stake pile body section length of side 1 is 600mm, and the corner cut length of side 4 is 50mm, and the area A calculating triangle stake is 152637 mm
2, girth u is 1650mm.And the Prefabricated Reinforced Concrete Square Pile area A that the length of side is 400mm is 160000 mm
2, girth u is 1600mm.As can be seen here, two kinds of pile-type are under the prerequisite of pile body girth u almost equal (namely vertical ultimate bearing capacity of single pile standard value is almost equal), and the pile body cross-sectional area of triangle stake is less than square pile, thus reach the target of saving construction costs.Further, due to the particular design of the present embodiment structure, anti-shot ability is comparatively strong, and higher, the prestressed, reinforced process of intensity is easier.
The utility model still has numerous embodiments, all employing equivalents or equivalent transformation and all technical schemes formed, and all drops within protection domain of the present utility model.
