Description

Special high-strength short pile for building reinforcement

Technical Field

The application relates to the technical field of building foundation reinforcement, in particular to a high-strength short pile for building reinforcement.

Background

The tubular pile is a reinforced concrete member for reinforcing a foundation mainly bearing a vertical load, and is divided into a prestressed concrete tubular pile, a prestressed concrete thin-wall tubular pile and a prestressed high-strength concrete tubular pile according to the concrete strength grade and the wall thickness.

Along with the comprehensive promotion of old district transformation work in cities and towns, in the work progress of carrying out old building transformation, often use the tubular pile to consolidate the basis of old building to strengthen old building's structural stability, at the reinforcement in-process, because old building form is various, the size differs, consequently need prefabricate the tubular pile of different length in advance according to the old building size of difference, so that the construction demand when prefabricated tubular pile can satisfy the basis and consolidate.

To the above-mentioned correlation technique, the inventor thinks that prefabricating the tubular pile of different length in advance needs prefabricating the tubular pile mould of different length, takes a lot of work and material when making the tubular pile mould to the tubular pile of longer length is inconvenient to dismantle and carry when the construction.

SUMMERY OF THE UTILITY MODEL

In order to improve the defect that tubular pile exists among the correlation technique, this application provides a special high strength short stake of refuting of building reinforcement.

The application provides a special high strength short pile of refuting of building reinforcement adopts following technical scheme:

the utility model provides a stake is refuted to special high strength weak point of building reinforcement, includes the pile body, is located the end plate at pile body both ends and buries a plurality of reinforcement muscle in the pile body underground, the length direction of reinforcement muscle is parallel with the length direction of pile body, reinforcement muscle tip with end plate fixed connection.

Through adopting above-mentioned technical scheme, foretell short pile of refuting has stable in structure, intensity height, the convenient advantage of preparation. When strengthening old building foundation, can select the short coaxial concatenation of refuting of different quantity according to concrete construction needs, and then assemble the tubular pile of the length that accords with the construction needs to the construction demand when can satisfying the foundation reinforcement to various old buildings. Refute the tubular pile of the required length of concatenation into construction through the weak point, need not to prefabricate the tubular pile mould of different length in advance on the one hand, saved construction cost and time, the foretell weak point of on the other hand refutes the stake and can transport to the construction site, then assembles the concatenation on the scene, refutes the stake for a short time and has the advantage of convenient to detach and transport in the transportation.

Optionally, the coaxial fixedly connected with of reinforcement muscle tip is spacing dish, spacing dish diameter is greater than the diameter of reinforcement muscle, set up the mounting hole that supplies spacing dish to pass on the end plate, the end plate in the hole of dodging that supplies the reinforcement muscle to pass is seted up to mounting hole one side, dodge the hole with the mounting hole intercommunication, the aperture of dodging the hole is less than the diameter of spacing dish.

Foretell structure is convenient for with reinforcing bar joint on the end plate to the follow-up welding operation of being convenient for can prevent through spacing dish that reinforcing bar from dodging downthehole droing, thereby has strengthened the short stability of refuting a skeleton, and then is favorable to improving the short holistic intensity of refuting a.

Optionally, a counter bore used for accommodating the limiting disc is formed in one side, away from the pile body, of the end plate, and the counter bore and the avoiding hole are coaxially arranged.

Through adopting above-mentioned technical scheme, make spacing dish be located the counter bore through setting to the counter bore to avoid spacing dish to bulge the end plate, can guarantee the aesthetic property of the stake of refuting for a short time on the one hand, on the other hand in follow-up centrifugal forming's in-process, the end plate lateral wall can be inseparable with the laminating of tubular pile mould, thereby be favorable to guaranteeing fashioned short steady quality of refuting the stake.

Optionally, the diameter of the counter bore is equal to the diameter of the limiting disc.

Through adopting above-mentioned technical scheme, spacing dish joint just can be in the counter bore to avoid spacing dish to rock in the counter bore, consequently strengthened the stability of being connected of reinforcement muscle and end plate, thereby be convenient for follow-up welding, and because spacing dish joint is in the counter bore, consequently can make the reinforcement muscle of different diameters remain stable. Foretell structure is favorable to reinforcing the stability of being connected of muscle and end plate, and then is favorable to improving short pile holistic stability and intensity of refuting.

Optionally, still include the stirrup, the stirrup is around locating a plurality ofly reinforcement bar periphery and with reinforcement bar fixed connection, the stirrup distributes along pile length direction spiral.

Through adopting above-mentioned technical scheme, when the stake skeleton is refuted to the preparation weak point, will strengthen muscle and end plate welding back, will add the muscle and weld with strengthening the muscle again, refute the holistic intensity of stake skeleton through setting up the stirrup and further strengthened the weak point, and then be favorable to improving the intensity of the fashioned weak point stake of refuting.

Optionally, a hoop plate is respectively disposed on one side of each of the two end plates, the hoop plate is cylindrical, the diameter of the hoop plate is equal to that of the end plate, and the hoop plate is coaxially and fixedly connected with the end plate.

Through adopting above-mentioned technical scheme, can effectively protect and wrap up the pile body perisporium through setting up the hoop board to improve the easy defect that produces the crack of pile body.

Optionally, the inner wall of the hoop plate is provided with a plurality of protrusions facing the center of the hoop plate along the circumferential direction.

Through adopting above-mentioned technical scheme, set up the interlock that the arch can strengthen pile body concrete and hoop plate to the stability of being connected of reinforcing pile body and hoop plate, and then be favorable to improving the holistic stability of short stake of refuting.

Optionally, the reinforcing rib is a twisted steel.

Through adopting above-mentioned technical scheme, the interlock power of reinforcement muscle and pile body concrete can further be strengthened to the reinforcement muscle of twisted steel to the pile body is refuted with the short connection stability of a skeleton, and then is favorable to improving the short holistic stability of stake of refuting.
