Description

Technical Field [0001] The present invention relates to a pile head reinforcing apparatus,

More particularly, the present invention relates to a pile head reinforcing apparatus for a pile head, and more particularly, to a pile head reinforcing apparatus for a pile head, which comprises a hanger and a reinforcing support holder, So that the installation work for reinforcing the head of the pile can be easily performed by a single worker, and at the same time, even after the concrete is poured to reinforce the head of the pile, The present invention relates to a pile head reinforcing apparatus for a stationary pile head, which is capable of minimizing corrosion due to contact with outside air and rainwater by preventing the reinforcing bars from being exposed to the outside.

In general, when constructing a building or a bridge, a steel pipe pile or a concrete pile is buried vertically with a hammer or the like on the ground, and then a vertical connection reinforcing bar is installed on the upper part of each pile to pour the expanded foundation concrete. In order to prevent deformation of the upper end of the pile due to the vertical load and sideways pressure acting on the upper and outer surfaces of the pile, a steel pipe or a pile head reinforcing structure is installed in the top portion of the pile supported by the pile.

Hereinafter, a head reinforcing structure of a pile according to the prior art is shown, and a pile reinforcing structure of a head of a concrete pile will be described as an example.

FIG. 1 is a perspective view of a pile head reinforcing apparatus according to the prior art, FIG. 2 is a perspective view of a pile head reinforcing apparatus according to the prior art, and FIG. 3 is a perspective view showing a pile head reinforcing apparatus Fig.

The pile head reinforcing apparatus 10 according to the related art as shown in Figs. 1 to 3 includes a bolt coupling means formed at an equal interval in the head portion which is a top face of a concrete pile (or a steel pipe pile 20) The lower end of which is coupled to each of the support plate 11 and the coupling holes 11a of the support plate 11 in which a plurality of engagement holes 11a are formed in the upper and lower outer peripheries, A plurality of bolting members 13 for hanging the hooking rods 12a of the hooking rods 12 to support the supporting plates 11, A nut member 14 screwed to the end of the bolt member 13 to prevent the hook 12a from coming off and fixing the bolt member 13 to the mounting groove 22 of the pile 20, And a plurality of through holes 15a are formed at equal intervals on the outer circumference of the bolt member 13 It consists geunji resin spacer 15 and a reinforcement supporting reinforced support member 16 for supporting a vertical connection reinforcement 17, which is fastened to the through hole (15a) of the spacer (15) through its center.

In the configuration of the pile head reinforcing apparatus 10 according to the related art as described above, the bolt coupling means for coupling the bolt members 13 for hanging are formed at equal intervals on the upper surface of the pile 20, And a mounting groove 22 formed by a V-shaped groove. The reason why the mounting groove 22 as the bolt connecting means is formed by the inverted triangular V-shaped groove is that when the mounting bolt member 13 is mounted on the mounting groove 22, the lower vertex of the mounting groove 22 The bolt head of the hanging bolt member 13 and the nut member 14 are caught on the inner and outer sides of the mounting groove 22 of the vertex portion when the bolt member 13 is engaged with the bolt member 13 on the mounting bolt member 13, So that the bolt member 13 can be fixed on the vertex of the mounting groove 22.

In the structure of the pile head reinforcing apparatus 10 according to the related art as described above, the fixing grooves 22 of the pile 20 and the coupling holes 11a of the support plate 11 are formed in the same number do. Therefore, when the hooking rod 12 is put on the using bolt member 13 which is fixed on the mounting groove 22, the hooking rod 12 is vertically slacked from the hanging bolt member 13 without turning.

The pile head reinforcing apparatus according to the related art as described above requires a pile mounting groove, a hooking bar, a hanging bolt member, and a rotating plate when the pile head reinforcing structure is supported on the head of a steel pipe pile or a concrete pile Workability and workability can be very good.

However, the pile head reinforcing apparatus according to the related art as described above requires many parts such as a mounting groove of a pile, a hooking rod, a bolt member for a hanging bolt, and a rotary plate.

In addition, the pile head reinforcing apparatus according to the related art as described above requires many parts such as a mounting groove of a pile, a hanger rod, a bolt member for hanging, and a rotary plate, so that the workability is good. However, There is a problem of delaying the air flow and increasing the construction cost.

[0006] On the other hand, as another conventional technique in which the above-mentioned problems are solved, a stationary pile head reinforcing apparatus (patent document 1) filed by the present applicant is disclosed.

The pile head reinforcing apparatus according to the related art is formed in a shape corresponding to the internal shape of a pile (steel pipe pile or concrete pile), and is installed at a certain depth of the pile, A plurality of vertically arranged reinforcing bars arranged vertically at upper portions of the vertical connecting steel bars and vertically connecting reinforcing bars arranged at regular intervals and being formed by bending the upper and lower portions of the vertical connecting steel bars and vertical connecting steel bars so that the placing pile head reinforcing apparatus is mounted on the head of the pile.

In other words, the prior art pile head reinforcing apparatus according to the related art is formed in a shape corresponding to the internal shape of the pile, and is installed at a predetermined depth of the pile, and is provided with a blocking plate for blocking a certain depth of the pile, Vertically connected reinforcing bars are arranged at regular intervals and are arranged in a row. Vertical connecting bars are used to reinforce the head of piles buried in the ground during the construction of buildings or structures of buildings or bridges. And a mounting part for bending a part of the upper part of the reinforcing bar to be mounted on the head of the pile.

As described above, the present invention provides a pier head reinforcing apparatus having a structure in which a mounting portion is formed on a vertically connecting reinforcing bar so that two-point support and five-point support can be performed, thereby further improving the workability of the passive head reinforcement structure, It is possible to greatly reduce the number of parts of the head-type head reinforcement structure, thereby facilitating the assembly work according to the construction.

In addition, as described above, it is possible to improve the price competitiveness through the structure in which the mounting portion is formed on the vertically connecting reinforcing bar, and to improve the workability due to the workability and assembly, thereby shortening the air.

However, as described above, since the mounting portion is exposed to the outside even after the concrete is poured to reinforce the head of the pile, the problem of the corrosion due to the contact with the external oxygen and the rainwater there was.

Further, since the construction in which the barrier plate and the plurality of vertically-connecting reinforcing bars are integrally formed is placed on the pile head, the worker can not easily deal with the heavy weight of the pile head and the worker must work together or use heavy equipment There is a problem that the efficiency of construction for reinforcing the pile head is remarkably lowered.

Therefore, it is possible to minimize the corrosion caused by the contact of outside air and rainwater by preventing the reinforcing bars, which are fixed on the pile, from being exposed to the outside even after the concrete is pushed for reinforcing the head of the pile, The research and development of a pile head reinforcement device is required.
