Description

Device for fabricating the reinforcement

The present invention relates to an apparatus for assembling reinforcing bars, comprising: an assembling jig for supporting a plurality of reinforcing bars in parallel and restricting movement; and a transportation device configured to move the assembling jig to the installation site and to elevate the assembling jig To a device for assembling reinforcing bars.

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an apparatus for assembling steel reinforcing bars to easily connect various types of reinforcing bars.

The present invention relates to an apparatus for assembling steel reinforcing bars, which is capable of setting a plurality of reinforcing bars on the ground, thereby improving ease of use and significantly shortening the construction time.

The present invention is characterized in that a plurality of reinforcing bars transferred by a transporting device are constructed so that an operator can be separated from the ground without rising on the upper side of the assembly jig and the fall prevention portion and the fall prevention portion are provided respectively in the transportation device and the assembly jig, To a device for assembling a reinforcing bar so as to be able to do so.

The present invention relates to an apparatus for assembling a reinforcing bar equipped with an adjustment restricting member so that the insertion depth can be adjusted in consideration of the position of the upper end of a reinforcing bar provided in advance in setting a reinforcing bar on the assembling jig.

The present invention relates to an apparatus for assembling reinforcing bars, which can separate reinforcing bars by connecting a plurality of reinforcing bars to a main frame and then moving the conveying device in one direction.

The present invention relates to an apparatus for assembling a reinforcing bar in which an assembly jig is selectively detachable from a transportation device and an elevator workbench is attached to allow an operator to ride.

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, The operation of coupling the reinforcing bars of the slab and the new reinforcing bars one by one, and the operation of coupling the hoops and the rest of the reinforcing bars to each other are performed at a high place, the structure of the coupler used therefor is complicated There has been a problem that working efficiency and workability are reduced due to many occurrences of time, manpower, and cost.

Further, since the operation of connecting the hoop and the stay to each of the above-mentioned reinforcing bars is performed at a high place, installation work such as a scaffolding such as a scaffold that can be moved or workable by workers is added, 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 and the hoops of the reinforcing bar are joined by the fastening lines in the pre-assembling method of the conventional reinforcing bars for reinforced concrete columns, the reinforcing bars are not rotated by the fastening lines, In order to combine the reinforcing bars with the mounting reinforcing bars of the slab, the reinforcing bars of the reinforcing net are connected to each other by rotating the coupler coupled to the mounting reinforcing bars.

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 net is fastened to the coupler. Among the reinforcing bars of the reinforcing net, 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 by the rotation of the coupler only by the rotation of the coupler, so that the overall durability, the vibration resistance, the compressive strength and the tensile strength of the reinforcing bar are deteriorated.

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.

To solve such a problem, Korean Patent No. 10-1457114 discloses a structure as shown in Fig.

The reinforcing net 40 including the main rope 41 and the stay 43 is assembled on the ground and the main rope 41 can be installed on the upper portion of the jig 10 provided with the plurality of mounting holes 11a A fixing table 30 is provided.

The fixing table 30 is provided with a coupler 50. The coupler 50 is fixed to a fixing hole formed in the fixing table 30 and is coupled to the main shaft 41. [

However, the related art has the following problems.

That is, after connecting the reinforcing bar 40 to the main rods 41 located at the lower side, the reinforcing bar 40 must be separated from the jig 10, the coupler 50, and the fixing block 30, Therefore, there is a problem that it takes much time to disassemble.

Further, in order to separate the reinforcing net 40 from the jig 10, a worker must climb to the top of the jig 10 to directly release the reinforcing net 40, which may cause a safety accident, which is not preferable.
