Abstract

The present invention relates to a high-strength concrete pile, and the foundation and coupling structure of the upper portion of the concrete pile in the foundation or groundwork of construction or civil engineering. It provides a circular plate and a rubber pad, and provides a fixed plate and wires fastened to the upper outer circumferential surface of the concrete pile so that the reinforcement and the circular plate can be fixed inside the concrete pile to prevent concrete from flowing into the pile when laying the foundation concrete. The head reinforcement structure of the pile.

Description

Reinforcement assembly of concrete file and building foundation}

The present invention relates to the head reinforcement structure of high-strength concrete piles in the foundation ground in the construction or civil engineering foundations, and relates to the joint reinforcement structure of the concrete pile and the foundation when the foundation is laid after arranging the head of the concrete pile.

In general, concrete pile foundation is one of the ways to reinforce the ground in case of deep foundation or soft ground in construction or civil engineering. It is the most used form in Korea at present.

In the conventional case, the concrete pile is entered into the ground to a certain depth, and the head of the concrete pile exposed to the upper ground is crushed to couple various fastening members to the exposed steel wire so that the reinforcing coupling is made, but the head crushing is performed. The process has been pointed out in terms of structural safety by causing longitudinal cracking of concrete and corrosion of internal steel wires.

Recently, the head of concrete pile exposed to the upper part of the ground is cut to a certain height, and concrete foundation and upper head reinforcement are installed in the hollow of concrete pile to install upper foundation concrete, but the internal hollow cross section of concrete pile is irregular. Difficulties and loss of concrete during pouring have been pointed out as problems.

An object of the present invention is to solve such a problem in the prior art, by cutting at a certain height of the concrete pile without breaking the upper end of the concrete pile and installing the head reinforcement assembly in the hollow portion of the concrete pile hollow In reinforcing the tofu by pouring and curing,

Circular plate and wire fixing plate for fixing to the upper part of the concrete pile resisting the load of the reinforced concrete is formed integrally and easy to assemble and install, the head reinforcement assembly of the concrete pile to solve the loss of concrete during concrete pouring The purpose is to provide.

The present invention is designed to reinforce the head of the concrete pile, the concrete pile is cut at a certain height and is installed on the top of the hollow part to maintain the horizontal state when placing concrete for reinforcing the head and rubber pads are installed along the edge of the circular plate. To prevent concrete loss caused by irregular hollow sections of concrete piles when concrete is being poured, and has a plurality of grooves in the circumferential direction in which the reinforcing steel mesh can be fixed on the upper surface of the circular plate, A head reinforcement is provided at the top of the concrete pile so that the circular plate can support the load by means of fixing plates and wires.

As described above, the concrete pile head reinforcement assembly of the present invention provides a head reinforcement assembly which can resist the load of the concrete when reinforcing by placing concrete in the hollow portion of the concrete pile and the loss of concrete during concrete pouring. It is designed to prevent the construction of circular plate, fixed plate, connecting wire and reinforcing reinforcing bar, and provides simple head reinforcing assembly that is easy to install during construction.

Figure 3 is a front view when installing the head reinforcement assembly according to the present invention.
Figure 4 is an enlarged view of the joint of the upper end of the head reinforcement assembly and the concrete pile in accordance with the present invention.
Figure 5 is an enlarged view of the joint of the head reinforcement assembly and the concrete pile hollow according to the present invention.

The present invention relates to a head reinforcement device of a concrete pile, the circular plate 200 and the concrete pile is cut to the upper end 700 of the concrete pile inclined to a certain depth in the ground and fitted to the hollow portion 800 to a predetermined depth Reinforcing reinforcing bar 400 and the reinforcing bar and the circular plate 200 therein to provide a fixed plate 500 and the wire 600 is fastened to the outer peripheral surface of the upper end 700 of the concrete pile to be fixed inside the concrete pile The head reinforcement assembly 100 of the concrete pile, the configuration is largely divided into a circular plate 200, reinforcing bar network 400, fixed plate 500 and the wire 600.

The circular plate 200 is formed with a plurality of vertical rebar mounting groove 210 in the circumferential direction on the upper surface to allow the vertical rebar 410 of the reinforcing steel mesh 400 is seated, the formwork to prevent concrete when reinforcing concrete is poured Play a role. The outer diameter of the circular plate 200 is smaller than the inner diameter of the concrete pile and the rubber pad 300 is installed along the edge of the circular plate 200 to prevent the concrete loss due to the irregular hollow portion 800 cross section of the concrete pile when placing concrete Make sure

The fixing plate 500 is fastened to the fastening of the wire 600 in the U-shape so as to cover the outer circumferential surface of the cut concrete pile upper end 700, the fixing plate 500 and the circular plate with a wire 600 200 is fastened.

The upper end of the reinforcing steel mesh 400 is provided with a spacer on the vertical reinforcing bars 410 so as to be spaced apart from the inner surface of the hollow portion 800 of the concrete pile in order to prevent the flow and ensure the coating thickness when concrete is poured.
