Description

Technical Field [0001] The present invention relates to a rotatable pile cap with spiral reinforcing rod,

The present invention relates to a pile cap for reinforcing concrete piles used in foundation work of a structure, in particular, it is constituted such that a plate body blocking a hollow portion of a large crush pile can be rotated 360 ° in any direction from its place, The present invention relates to a rotary reinforcing pile cap having a reinforced reinforced concrete structure which is constructed to be able to freely rotate two reinforcing reinforcing bars as a rotary plate.

In general, for the purpose of strengthening the ground in the foundation construction, hollow concrete pile or foundation pile is put into the ground, and then the head of the pile protruding from the ground is raised to a certain height And the concrete mortar is poured into the inside of the pile embedded in the ground. In order to reduce the material loss of the concrete mortar generated due to the concrete mortar being poured into the inside of the hollow foundation pile, The hollow section of the upper part of the pile is covered with a circular plate with reinforcing bars and then the prepared concrete mortar is pushed into the hollow part of the concrete pile to fix the hollow part and the reinforcing bars are fixed integrally from the concrete pile. A plurality of rebar reinforced from the concrete pile And the basic reinforcement work on the ground is completed by carrying out a foundation laying work for connecting the foundation (see Patent Document 2 below).

However, in order to interconnect the reinforcing bars introduced from the support plate of the pile cap with the foundation bars, in order to facilitate the interconnection work between the reinforcing bars installed in the pile cap and the foundation bars reinforced horizontally, Prior to pouring the concrete into the hollow of the pile, the supporting plate of the pile cap is rotated from the large crits file to the left and right directions so that the corresponding reinforcing bars are aligned with each other, and then the concrete is poured, And the support plate body is integrally fixed to the concrete pile.

A file cap for facilitating the adjustment of these reinforcing bars is a file cap described in Patent Document 1 described below. This file cap is already registered by the present applicant.

However, the pile cap proposed in the following patent document is constructed so that the rotation angle of the rotary plate provided with the reinforcing bars can be rotated only to a predetermined angle by a guide hole of a predetermined length provided on the circular plate, There is no other choice. This limitation of the rotation range makes it difficult to adjust the position of the reinforcing bars mutually, and as a result, it is difficult to operate the supporting plate body itself from the concrete file. As a result, unnecessary working time and manpower are required for installation work of the reinforcement cap, thereby reducing workability of the reinforcing pile cap.

Accordingly, there is a desperate need to develop a file reinforcement cap having reinforcing bars having at least two or more reinforced reinforcing bars that can be freely adjusted from a support plate to a desired position.

Rotational reinforcing pile cap 100 with mixed reinforcing bars according to the present invention, as shown in the drawings, has a hollow portion 2 (see Fig. 4) of pile 1 having a plurality of foldable blades 112, And a rotating circular plate 120 made of a metal material such as the fixed circular plate 110 which is coupled to the stationary circular plate 110 and rotates in 360 ° in either the left or right direction. . The fixed disk (110) and the rotating disk (120) constitute a plate for blocking the file.

A plurality of linear reinforcing bars 132 having a predetermined length are arranged in the vertical direction while being arranged in the same circular shape as the rotary disc 120 on the rotary disc 120 constituting the punching plate. The number of the linear reinforcing bars 132 may be arbitrarily changed in proportion to the size of the rotary disk 120. The linear reinforcing bars 132 can be firmly fixed to the rotary disk 120 by welding or riveting.

A spiral reinforcing bar 134 is installed at the entire outer periphery of the linear reinforcing bars 132 so as to be spirally wrapped from the lower end of the linear reinforcing bars 132 to the upper end thereof have. The helical reinforcing bars 134 are integrally fixed through a welding operation at a portion facing the linear reinforcing bars 132 to give a reinforcement that fixes the linear reinforcing bars 132 without movement. The spiral reinforcing bars 134 are combined with the straight reinforcing bars 132 to form a sound mixed reinforcing bar member 130. In this mixed reinforcing steel member 130, the linear reinforcing bars 132 are integrally fixed to the upper portion of the linear reinforcing bars 132 at a predetermined position so as not to move, so that the upper ends of the concrete piles 1 (see FIG. 4) A fixing member 140 for providing a locking projection 142 provided with a latching portion for catching is integrally fixed by a welding operation.

A configuration in which the rotary disk 120 is rotated 360 degrees from the fixed disk 110 will be described with reference to FIG. 3 as shown in FIG. 3 is an enlarged view of the portion "A" in Fig.

As shown in the drawing, the rotary disk 120 is configured to be able to rotate in any direction in either the left or right direction from the fixed disk 110 (see FIG. 4). This rotation of the rotary disc 120 is achieved by the guide bosses 116 having a substantially L-shaped configuration and protruding downwardly from the rotary disc 120 at predetermined intervals along the circumference of the rotary disc 120, 4) supported by the guiding jaws 116 by the structure in which the rotary disk 120 is movably coupled to the peripheral edge 114 of the central hole 113 of the rotary disk 120.

This rotational movement makes it possible to adjust the position of the mixed reinforcing steel member 130 while rotating and moving the fixed position of the mixed reinforcing steel member 130 to a desired position. Thus, compared to the configuration in which the pile cap provided in the conventional patent document is rotated at a limited angle, The effect is improved.

Fig. 4 is a view showing a state in which a rotary reinforcing pile cap 100 according to the present invention is installed on a hollow portion 2 of a foundation concrete pile 1. Fig.

The pile cap 100 for rotary reinforcement according to the present invention is inserted into the hollow portion 2 of the foundation concrete pile 1 in which the head assembly has been completed in advance and is inserted into the mixed reinforcing steel member 130 And the protrusion 142 of the fixing member 140 protruding in all directions is supported in a state of being hooked on the upper surface of the pile 1 so that the fixed disc 120 is coupled with the rotating disc 120 The blocking plate is installed so as to close the hollow portion 2 of the foundation concrete pile 1. [ Further, the mixed reinforcing steel member 130 installed from the rotary disk 120 is provided as a reinforcing member of an incandescent work projected from the upper end of the foundation concrete pile 1 and connected to the foundation steel. In this case, The concrete is inserted into the hollow portion 2 of the foundation concrete pile 1 for convenience of connecting the other mixed reinforcing steel member 130 of the cap 100 to the reinforcing bars used for the foundation foundation. It is necessary to adjust the positions of the mixed reinforcing steel member 130 to match with each other before the pile 100 is inserted. The pile cap 100 of the present invention is formed by a rotary disk 120 coupled to the fixed disk 110, It can be freely rotated and moved in 360 degrees. In addition, the present invention has the effect of further enhancing the reinforcement of the foundation pile by using the mixed reinforcing steel member 130 in addition to the convenience of the position adjustment operation of the mixed reinforcing steel member 130 as described above.

The sharpened cutting portions of the upper ends of the mixed reinforcing steel member 130 are formed into a hemispherical surface portion 136 forming a smooth curved surface or formed as a bent portion 138 so that the work process of the workers or the transportation of the pile cap In the course of the process, workers are stabbed at the sharp top of the reinforcing bars to protect themselves from safety hazards such as injuries to the body. In order to prevent such safety accidents, there has been proposed a structure in which a rubber cap or the like is installed at the upper end of reinforcing bars. However, there is a difficulty and inconvenience that the rubber cap must be covered at the upper end of the reinforcing bars. And the rubber cap is torn or separated from the rubber cap.

The present invention makes it possible to freely rotate the rotary plate provided with the mixed reinforcing bars in a desired direction, thereby making it possible to more conveniently and freely set the position of the reinforcing bars at the time of work. Further, by using the mixed reinforcing bars, This gives us the advantage of making the base file more robust.
