BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a method of assembling a reinforcing net and a device used therein, and more particularly, to a method of assembling a reinforcing net, The present invention relates to a method of assembling a reinforcing bar net so that it can be conveyed.

Generally, when constructing a high-rise building, concrete is laid on the floor to construct a floor, then a plurality of pillars are placed on the floor, concrete is laid on the floor, and a slab is constructed to construct the building one by one . At this time, a column or beam (hereinafter, referred to as "column") of the building is constructed by embedding a plurality of reinforcing bars in concrete so as to have sufficient durability, vibration resistance, compressive strength and tensile strength.

In order to construct the column, a new reinforcing bar must be connected to each reinforcing bar having an end protruding from the upper surface of the slab. That is, the coupler is coupled to the end of each reinforcing bar located on the upper surface of the slab, A new reinforcing bar is set up on the side of the coupler so that the new reinforcing bar is positioned on the upper side of the coupler by using a crane or by a worker directly. When the coupler is rotated, the end of the new reinforcing bar is inserted into the coupler, And a new reinforcing bar is connected and connected to each reinforcing bar of the slab in this manner.

Thereafter, a plurality of hoops are installed between the upper and lower portions of the reinforcing bars installed on the upper portion of the slab, and then the reinforcing rods and the hoops are combined with each other and the plurality of the rails are combined. Construction of a reinforcing net for construction, that is, a reinforcing net including a plurality of reinforcing bars, a hoop and a stay, is completed.

However, in the conventional reinforcing bar construction, in order to connect the reinforcing bars of the slab to the new reinforcing bars, a crane or an operator directly places new reinforcing bars on the upper portions of the reinforcing bars of the slab, And the new reinforcing bars are connected one by one to each other by rotating the coupler by rotating the coupler in a state where the reinforcing bars are connected to the reinforcing bars, , The cost and the like, and the work efficiency and the workability are deteriorated.

In addition, connecting the hoop and the carpet to each of the above-mentioned reinforcing bars increases the cost of construction due to the addition of a scaffolding structure such as a scaffolding which can be moved or workable as the worker moves, There is a problem in that there is a high risk of a safety accident in which a worker falls due to a carelessness or mistake of an operator or a erroneously installed footstep structure during work at a high place.

In order to solve this problem, Korean Patent Registration No. 10-0863974 'Pre-assembling method of reinforcing net for reinforced concrete column' is interposed, and a plurality of reinforcing bars, that is, a plurality of upper and lower and lower sides, A plurality of hoop rods and tie rods are installed on the outer circumferential surface thereof, and then a reinforcing net in which the hoop rope and the tie rope are joined to each reinforcing bar is assembled by a fastening line (not shown) The reinforcing bar is moved to the place where the net is to be installed and is positioned on the upper side of the mounting reinforcing bar protruding from the upper surface of the bottom concrete. Then, the coupler coupled to the mounting reinforcing bar is rotated so as to move toward the reinforcing bar net, Construction of the network is completed.

However, since the reinforcement bars of the reinforcing bar are coupled by the fastening lines in the pre-assembling method of the reinforcing bar for the conventional reinforced concrete columns, the reinforcing bars of the reinforcing bar are not rotated by the fastening lines, In order to connect the reinforcing bar and the mounting reinforcing bar of the slab, the coupler coupled to the mounting reinforcing bar is rotated to connect the reinforcing bar of the reinforcing bar to the reinforcing bar of the reinforcing bar.

Since the connection between the reinforcing bars of the reinforcing net and the reinforcing bars of the bottom concrete is made by the rotation of the coupler, the crane continues to hold the reinforcing net lifting state until the bonding operation between the reinforcing bars is completed There is a problem that the workability and the work efficiency are deteriorated because a large amount of time, manpower, and cost are required for the construction work of the reinforcing bar network.

When the lengths of the reinforcing bars are different from each other, only a part of the reinforcing bars of the reinforcing bar is fastened to the coupler. Of the reinforcing bars, the short reinforcing bars are not fastened to the coupler, The reinforcing bar can not be coupled with the reinforcing bar having a short length in the reinforcing net by the rotation of the coupler only in the state of the reinforcing bar, so that the overall durability, the vibration resistance, the compressive strength and the tensile strength of the reinforcing bar are lowered.

In addition, since the reinforcing bars are connected to the hoop and the hoist by the fastening lines, when the hoist net is erected with the crane, there is a problem that the entire reinforcing bars are twisted , The twisted reinforcing bar network can not be restored to its original state, so that the reinforcing bars of the reinforcing bar network can not be connected to the reinforcing bars of the floor concrete.

Korean Registered Patent No. 10-0863974 (October 10, 2008) Patent Registration No. 10-1457114 (November 11, 2014) Japanese Patent Application Laid-Open No. 10-2013-0115012 (Oct. 21, 2013)
