Abstract

The present invention relates to a fall prevention safety device that can prevent safety accidents in the work process of various steel pipe piles.

According to the present invention, in the case of steel pipe piles that are variously used for ground reinforcement such as building foundations, machine foundations, bridges, retaining wall foundations, etc., construction works are performed using driving operations, and the predetermined work is completed near the ground. At this time, the steel pipe pile is a steel pipe type, so there is a deep hole inside, and the hole is deep and contains groundwater or seawater depending on the working area. The purpose is to provide a steel pipe pile fall safety device. In order to achieve the above object, the present invention firmly connects a round band-shaped iron band on the upper part of the steel pipe and a cross-shaped square pipe on the inner part of the iron band, and connects the screws to one part of the iron band. Forming the steel strip to the upper part of the steel pipe pile and tighten the screws of the connection to secure the safety device to be able to loosen and dismantle if necessary, characterized in that it has a safety device for preventing the steel pipe pile fall.

The present invention relates to a safety device for preventing steel pipe piles from falling down. The cross-shaped square pipes are fixed to each other on the inner side of a round band-shaped steel band, and a portion of the steel band is formed by connecting a screw to tighten the steel strip body. It is related to the steel pipe pile fall prevention safety device that is supported on the steel pipe piles by inserting the top of the pile and tightening the screws of the connection to form a fall prevention safety device to prevent accidents that may occur in case of accident.

In general, various kinds of conventional steel pipe piles do not have any special measures or are slightly larger after work. Most of them are temporarily mounted by welding with reinforcing bars using steel reinforcement and then forcedly removed when arranging heads. It has a standard of more than 900mm, and it is usually supported over 20m underground and it is located near the ground because the foundation work should be done at the upper part of the steel pipe pile after the work is completed. Therefore, groundwater or seawater is one of the vulnerable parts of our society, which can cause danger to workers if there is no safety device, and can be used for dead bodies of criminals.

Therefore, the object of the present invention is to solve the conventional problems, in order to prevent the fall of the operator or the work tool during the steel pipe pile work in the form of a round band-shaped steel strip and a square pipe that fits the steel pipe pile diameter inside the cross in the cross shape It is connected to each other and the connection part is attached to the one part of the steel strip so that it can be tightened, and this iron band is inserted on the upper part of the steel pipe pile, and the screw of the connection part can be tightened and fixed so that it can withstand the direct load. It can be easily removed by unscrewing the connection screw if it is necessary to prevent human injury or safety accidents in the course of work, and to be able to reuse it in subsequent work or other steel pipe pile work. The purpose is to prevent accidents in advance.

According to the present invention, the iron band 100, the square pipe 110, the connecting portion 120, the screw 130, etc. using a round band-shaped iron band 100 and the cross-shaped square pipe inside the iron band 100 (110) is fixed to the iron strip 100 and connected to each other, and one part of the iron strip 100 to form an angle to each other and to form a connection portion 120 to form a hole so as to fit the screws 130 in each angle portion By inserting the inner side of the steel strip 100 into the upper pipe pile and tightening the screw 130 of the connecting portion 120, the safety device is fixed to the upper steel pipe pile to withstand the direct load can act as a safety device and follow-up work or For demolition is a steel pipe pile fall prevention safety device to be released by dismantling the screw 130 to be reused in other steel pipe piles.

1 is a planar configuration diagram according to the present invention, a cross-shaped square pipe 110 of the round band-shaped iron strip 100 and the iron strip 100 are connected to each other and each part in an angle shape in one portion of the iron strip 100. Form a hole in the angle and put the connecting portion 120 to insert the screw 130, the iron strip 100 is inserted into the top of the steel pipe pile, and tightening the screw 130 of the connecting portion 120 to the steel pipe pile and this safety The devices are fixed to each other and made a safety device to withstand the direct load, and if necessary to remove it by loosening the screw 130 of the connecting portion 120 if removed.

Figure 2 is a structural diagram (cross-sectional view) installed on the steel pipe pile by the present invention is connected to the cross-shaped square pipe (110) of the iron strip 100 and the inner side of the iron strip 100 and connected to one part of the iron strip 100 ( 120 and put the screw 130 in the connection portion 120 to insert the steel strip 100 to the upper pipe pipe pile and tighten the screw 130 installed in the connection portion 120 to be fixed to the steel pipe pile outer diameter It is a structural diagram (section view) so that the safety device can be fixed on the steel pipe pile.

Figure 3 is a state diagram of the steel pipe pile fall prevention device is installed on the steel pipe pile as a state diagram of the embodiment.

The steel pipe pile fall safety device is able to withstand the load in the form of a lattice and more in addition to the cross shape according to the diameter of the steel pipe pile, and can function as a safety device for the steel pipe pile fall prevention.

As described above, according to the present invention, it is a useful design that can prevent accidents in which a worker, a person, a work tool, etc. fall into a steel pipe pile when working various steel pipe piles at a construction site.

Claims (1)
