Abstract
The present invention provides a guide device for connecting concrete files. The guide device for connecting a concrete file includes a fixed body part detachably installed on an upper end of a lower file to be buried in the ground; A guide body disposed along the upper circumference of the fixed body and guiding the lower end of the upper file introduced from the upper portion to the upper end of the lower file to guide the lower end of the upper file to the upper end of the lower file; And a weld portion provided at an upper end of the fixed body portion and welding the lower end of the upper file and the upper end of the lower file when the lower end of the upper file and the upper end of the lower file are in uniform contact.
Description
The present invention relates to a guiding device for connecting concrete piles, and more particularly, it relates to a guiding device for connecting concrete piles, more particularly, to guiding upper files to be vertically connected to upper ends of lower piles and welding when end portions of piles are uniformly contacted with each other. And a guide device for connecting concrete piles, which can remove moisture generated around a welded part in real time.
Normally, the reinforcing plate is welded to the inner circumferential surface of the steel pipe file, the cover plate is welded to the upper end of the steel pipe file, and the steel pipe is welded around the lid plate.
This requires laborers to individually weld the cover plate and the rebar in the field, which increases labor and production costs.
Further, welding heat causes deformation, cracks, weakening of the texture and corrosion of the welded portion.
In addition, there is a problem that welding may be dropped due to a small welding area, and the structure may be damaged due to a weak vertical load.
There is also a bolt-type steel pipe pile head reinforcement method. This is accomplished by piercing a number of bolt holes on the side of the steel pipe with hydraulic air, inserting the bolt-type steel pipe pile head reinforcement cover plate into the steel pipe, assembling the bolt on the side of the steel pipe file, Assemble the lower cast iron and the reinforcement bar, fasten the normal rebar and screws to the circular cover plate, assemble the reinforced base of the expanded base and pour the concrete.
This is because there is no on-site welding process and the use of a prefabricated cover plate is expected to shorten the construction time, but it is difficult to carry and transport the cover plate.
Further, a cruciform reinforcing plate is inserted into the inside of the steel pipe and welded to the inside of the steel pipe, the circular lid plate and the steel pipe pile head are welded to each other, and a plurality of vertical reinforcing bars are fillet welded around the outer side face of the steel pipe pile, Assemble the rebar and place concrete on it.
This is because the steel pipe file does not require concrete filling to the inner side, but it is difficult to weld the steel pipe in the field, and it is difficult to assemble the reinforced foundation steel, transportation is difficult, and construction cost is high.
It is an object of the present invention to provide an apparatus and a method for guiding upper files to be vertically connected to upper ends of lower files and automatically performing welding when ends of the files are uniformly contacted with each other, And a guide device for connecting a concrete file which can be removed in real time.

The guide device for connecting a concrete file includes a fixed body part detachably installed on an upper end of a lower file to be buried in the ground; A guide body disposed along the upper circumference of the fixed body and guiding the lower end of the upper file introduced from the upper portion to the upper end of the lower file to guide the lower end of the upper file to the upper end of the lower file; And a weld portion provided at an upper end of the fixed body portion and welding the lower end of the upper file and the upper end of the lower file when the lower end of the upper file and the upper end of the lower file are in uniform contact.
The welding portion may include a plurality of pressure sensors installed at a plurality of positions on the upper circumference of the lower pile and measuring the contact pressures of the lower pile of the upper pile guided around the lower pile and a rail installed along the lower end of the guide body, A welder installed to move along the rail and welding the upper end of the lower file and the lower end of the upper file that are in contact with each other through an external power source as they are moved, a linear motor for controlling the movement of the welder, And a controller for driving the linear motor and the welder to weld the upper periphery of the lower pile and the lower end of the upper pile when the measured contact pressures fall within a predetermined error range.
It is preferable that the guide body portion includes a support member, a plurality of pressure members, and a plurality of cylinders.
The pressing member may have a rounded end and be elastically protruding through an elastic spring at an end of the shaft.
The support member is installed along the upper circumference of the fixed body and is formed to protrude outward.
The plurality of pressing members are installed adjacent to each other along the upper circumference of the fixed body portion.
Each of the plurality of cylinders includes a shaft to be expanded and contracted, and a cylinder body for receiving a control signal from the controller to expand and contract the shaft.
The end of the shaft is connected to the plurality of pressing members.
The cylinder body is hinge-connected to the upper end of the support member.
As the shaft of each of the plurality of cylinders is expanded and contracted, the plurality of pressing members are rotated.
Wherein the controller is configured to expand and contract the axis of each of the plurality of cylinders so that the contact pressures measured from the plurality of pressure sensors are included in the error range to independently rotate each of the plurality of pressing members, It is preferable to allow the circumference to be pressed at a plurality of positions.
A moisture removing portion may be provided around the upper end of the fixed body portion.
The moisture removing unit may include a cover member extending outward from the upper end of the fixed body to cover the welded portion from the upper portion of the fixed body portion and a cover member disposed at a plurality of positions of the lower end of the cover member to heat the introduced outside air, And a plurality of blowers for forcibly supplying the water to the welding part and drying and removing the moisture generated in the welding part.
Each of the plurality of blowers is preferably repeatedly rotated so as to be swingable through rotation motors driven by a signal from the controller.
In the present invention, the upper file is guided to be vertically connected to the upper end of the lower file, and when the end portions of the files are uniformly contacted with each other, the welding is automatically performed to remove moisture generated around the weld in real time It has the effect of giving.
