Abstract
The utility model discloses a variable-reinforcement anti-pulling square concrete pile. The variable-reinforcement anti-pulling square concrete pile is composed of concrete and a steel reinforcement framework, wherein the steel reinforcement framework is formed by arraying steel reinforcements in a square shape, and fixing the steel reinforcements via hoop reinforcements; and draw reinforcements are arranged on the diagonal lines of the steel reinforcements which are arrayed in a square shape, and the draw reinforcements and the hoop reinforcements are arranged in the same plane, so as to form the steel reinforcement framework. According to the variable-reinforcement anti-pulling square concrete pile disclosed by the utility model, the anti-pulling capacity and the overall performance of the steel reinforcement framework are further improved by virtue of the draw reinforcements which are arranged in a diagonal crossing manner, thus guaranteeing no deformation of the steel reinforcement framework, and then guaranteeing the pile-forming quality of the concrete pile; and moreover, the lateral circumference areas of round piles with the same diameter are increased via square sections, thus improving the anti-pulling capacity of the concrete pile during use, guaranteeing project quality, reducing the dosage of concrete and the dosage of the steel reinforcements, and reducing project expense.
Description
Affiliated technical field
The utility model relates to a kind of building foundation field product, specifically a kind of change arrangement of reinforcement resistance to plucking square concrete stake.
Background technology
Develop rapidly along with economic construction, highrise building and some other large-scale municipal structure are more and more, pile foundation due at the vertical compression bearing capacity and control reliability that sedimentation provides with and the adaptability of various geological conditionss has been subject to increasing application.Be widely used at present the square concrete stake as the resistance to compression foundation pile that also mainly bears straight down in the realm of building construction, mainly vertical reinforcement and the concrete by stirrup and elongated uniform section area consists of.the impact that be connected with perpendicular muscle by self deadweight and stirrup due to cage of reinforcement, no matter be prefabricated or carry out cast in situs, reinforcing bar all can produce distortion or displacement in various degree, distortion, and when adopting cast in situs, the external force that concreting produces can increase the weight of the distortion of reinforcing bar, will cause so the stressed and different design of the inhomogeneous and cage of reinforcement of thickness of concrete cover, thereby changed the stressed proterties of square concrete stake, can not bring into play by designing requirement the ability of its intensity and resistance to deformation, and in different directions Load Combination situation, when especially bearing pulling force straight up, the factor that reduces gradually of the suffered pulling force of considering soil lateral development of resistance not, and adopt elongated equivalent arrangement of reinforcement, namely wasted reinforcing bar, have and really to bring into play its extraction-resistant behavior, when having affected safety of building, concrete and reinforcing bar have been wasted.
Summary of the invention
The problem that exists when having square compressed concrete stake as uplift pile now in order to solve, the utility model provides the stake of a kind of change arrangement of reinforcement resistance to plucking square concrete, the stake of this resistance to plucking square concrete not only has good resistance to plucking, and can effectively keep the resistance to plucking ability of concrete pile when gradually reducing quantity of reinforcement, saved simultaneously reinforcing bar and concrete.
The technical scheme that its technical problem that solves the utility model adopts is: it is to be made of concrete and cage of reinforcement, wherein cage of reinforcement is by square arrangement with reinforcing bar, by stirrup, it is fixed, and being provided with lacing wire on the diagonal of the reinforcing bar of square arrangement, lacing wire and stirrup are arranged in same plane.The utility model utilization is resistance to plucking and the overall performance that diagonal angle lacing wire arranged in a crossed manner has further improved cage of reinforcement; thereby guarantee that cage of reinforcement is indeformable; and with increasing the concrete in tension area by the intersection lacing wire; to guarantee the pile quality of concrete pile; also reducing maintenance concrete pile resistance to plucking ability in use under the amount of reinforcement prerequisite simultaneously; guarantee workmanship, saved amount of reinforcement.
The beneficial effects of the utility model are: not only have good skeleton and support and connection function; and can effectively guarantee the pile quality of concrete pile; the uplift resistance that keeps the concrete pile of the identical length of side when reducing rolled steel dosage; guaranteed safety of building; product structure is simple; cost is low, easily promotes the use of.

1,2,3, the 4-reinforcing bar code description in figure:; The 5-stirrup; 6,7-lacing wire; 8,9,10,11-reinforcing bar; The 12-concrete.
The specific embodiment
As shown in Figure 1, the utility model is made of concrete (12) and cage of reinforcement, wherein cage of reinforcement includes reinforcing bar (1,2,3,4), stirrup (5) and lacing wire (6,7) composition, the reinforcing bar arrangement that is square, be fixed by stirrup, as shown in Figure 2, in use the stirrup of varying number can be set according to designing requirement, to form skeleton and to guarantee that cage of reinforcement is indeformable, increase its stability and shear resistance.Be provided with lacing wire on the diagonal of the reinforcing bar of square arrangement, be positioned at same plane with stirrup, lacing wire can be played fixedly reinforcing bar, prevents the distortion that cage of reinforcement produces when being subjected to own wt or External Force Acting, stability and the pulling test strength of cage of reinforcement have been promoted, thereby also guaranteed the pile quality of concrete pile, make concrete pile have good resistance to plucking effect, and then can guarantee construction engineering quality.
As shown in Figure 3, when needs adopt the concrete pile of large-size, can set up reinforcing bar (8,9,10,11) by designing requirement.Need to prove, the reinforcing bar of setting up, stirrup and lacing wire quantity all can increase according to actual conditions, and are not limited only to the quantity that exemplifies in the utility model scheme.
Claims (2)
1. one kind becomes the stake of arrangement of reinforcement resistance to plucking square concrete, includes cage of reinforcement and concrete, and wherein cage of reinforcement is made of reinforcing bar, the stirrup of arranging that be square, and it is characterized in that: be provided with lacing wire on the diagonal of the reinforcing bar of square arrangement.
2. a kind of change arrangement of reinforcement resistance to plucking square concrete according to claim 1 stake, it is characterized in that: lacing wire and stirrup are in same plane.
