Description
The present invention relates to a concrete pile, and more particularly to a concrete pile produced by centrifugal molding.
In general, in the case of erecting a building or structure, in order to support the upper structure according to the condition of the ground or the load of the building or structure, the foundation construction to reinforce the ground.
As a result, a shallow foundation or a deep foundation is performed according to various conditions such as the load of the structure and the ground conditions. The case where the root width ratio is 1 or less is called the shallow foundation, and the case where the root width ratio is 1 or more is defined as the deep foundation. .
In the case of the shallow foundation, the structure is directly supported on the ground without using the pile, and the pile is used to reinforce the bearing force when the ground under the structure cannot support the load of the upper structure.
The piles can be classified into steel pipe piles, concrete piles, composite piles, etc., depending on the material.
Recently, PHC piles manufactured by centrifugal force and autoclave curing are widely used among concrete piles. The PHC pile is a high-strength pile with a pretensioning method. The allowable compressive stress of the concrete is so large that it can withstand a great celebration. The prestress is introduced into the concrete to provide excellent impact strength and excellent tensile stress.
1 is a diagram showing such a conventional PHC file. As shown in FIG. 1, in the conventional PHC pile, a
In order to increase the tip bearing capacity of the PHC pile formed as described above, a reinforcing
However, in the PHC pile according to the prior art, since the lower shoe plate is not a structural member that bears a load, it is generally formed to have a thin thickness in consideration of economical efficiency, so that the PC steel wire is deformed to the member when being tensioned with a strong tensile force. There was a prone problem.
In addition, in the conventional PHC pile, the reinforcement plate as a structural member that bears a load in order to reinforce the tip bearing capacity of the pile has to be installed separately in the field or factory after curing the concrete of the PHC pile. There was a problem that the installation of a large reinforcing plate was not easy.
An embodiment of the present invention is to provide a concrete pile manufacturing apparatus and a concrete pile manufacturing method using the same, which can increase the tip bearing capacity, despite the simplified lower structure of the concrete pile.
According to one embodiment of the invention, it is formed in a plate shape, a plurality of insertion hole blocking projections protruding on one surface is disposed in the circumferential direction, characterized in that formed through the plurality of formwork coupling holes through the outer side of the insertion hole blocking projections Provided is a blocking plate for producing a concrete pile.
The inside of the insertion hole blocking protrusion is formed to further protrude a concrete pile hollow blocking protrusion.
On the other hand, according to another embodiment of the present invention, it is formed in a plate shape, a plurality of reinforcing plate coupling holes are arranged in one circumferential direction, characterized in that formed through the plurality of formwork coupling holes through the outer side of the reinforcing plate coupling hole. A blocking plate for producing a concrete pile is provided.
According to another category of the present invention, a formwork for forming a concrete pile; A reinforcing plate located at one end of the formwork; And a blocking plate positioned on an opposite surface of the formwork with the reinforcing plate interposed therebetween, wherein the blocking plate is fixed to the formwork, and the reinforcing plate is formed by passing through a plurality of insertion holes into which the tension member is inserted. The surface of the contact with the reinforcing plate is provided with a concrete pile manufacturing apparatus characterized in that the insertion hole blocking portion is formed to be inserted into the insertion hole.
The insertion hole blocking portion includes an insertion hole blocking protrusion protruding from a surface of the blocking plate contacting with the reinforcing plate.
The insertion hole blocking part includes a reinforcing plate coupling hole formed to penetrate to communicate with the insertion hole of the blocking plate, and the insertion hole blocking bolt fastened to the reinforcing plate coupling hole and the insertion hole.
The reinforcing plate, the locking step is formed that can be caught on the inner peripheral surface of the formwork.
According to another category of the invention, the present invention comprises the steps of preparing a reinforcing bar assembly by assembling the tension member, the reinforcing bar assembly into the lower formwork; Disposing a reinforcing plate at one end of the lower formwork; Fixing the tension member to a tension hole formed in the reinforcement plate; Installing a blocking plate installed on an opposite side facing the lower formwork of the reinforcing plate; Fixing the other end of the tension member to a tension device; Injecting concrete into the lower formwork and fastening the upper formwork to the lower formwork; Driving the tension device to tension the tension member; Curing after the centrifugal molding in the tensioned state of the tension member; And after curing, the step of removing the blocking plate; provides a method for manufacturing a concrete pile integrated reinforcement plate comprising a.
The installing of the blocking plate may be performed by bolting the blocking plate to the reinforcing plate.
A plurality of insertion holes through which the tension member is inserted are formed in the reinforcing plate, and a thread is formed in the inner diameter of the insertion hole, and the blocking plate is formed through the reinforcing plate coupling hole to communicate with the insertion hole. It is preferable to fasten the reinforcing plate coupling hole and the insertion hole with an insertion hole blocking bolt.
The installing of the blocking plate may further include fixing to the lower formwork.
In the fixing of the lower formwork, it is preferable that the blocking plate formed with a plurality of formwork coupling holes is bolted to the lower formwork through the formwork coupling holes.
According to one embodiment of the present invention, the following effects are expected. However, it is not necessarily falling within the scope of the present invention if all of the following effects are exerted.
Conventionally, after the tension member is fixed to the lower shoe plate, the lower shoe plate is fixed to the support plate for fixing in order to fix the lower shoe plate when the tension member is tensioned, and after curing the poured concrete, demoulding the fixing support plate again, and reinforcing plate Although the construction process was complicated and the procedure was cumbersome, such as fixing to the lower shoe plate again, according to the present invention, there is no need for the lower shoe plate and the fixing support plate. Simultaneous with the demoulding, since the reinforcing block is installed on the concrete pile, the manufacturing process is simple and the component parts can be omitted, thereby reducing the manufacturing cost.
In addition, the blocking plate not only prevents the concrete from leaking through the holes of the reinforcing plate, but also the reinforcing plate is fixed between the blocking plate and the formwork, thereby preventing the reinforcing plate from being deformed when the tension member is tensioned.
In particular, the blocking plate is firmly fixed to the reinforcement plate by using the insertion hole blocking bolt, so that the blocking plate and the reinforcing plate behaves as a composite member with respect to the load, so that the load supporting ability (the ability to hold the tension member without being deformed against the tensile force) is It can be much increased.
Due to such an effect, it is possible to prevent the thickness from being thicker than necessary in order to prevent deformation occurring when the reinforcing plate is tensioned.
