Description

  The present invention relates to a rebar net assembly method and an apparatus used therefor, and more specifically, each main bar of a rebar net and each main bar of a slab to be installed for constructing columns and beams are easily and easily coupled to each other. The present invention also relates to a method for assembling a reinforcing bar net that can be transferred.

  Generally, when constructing high-rise buildings, after placing concrete on the bottom and constructing the bottom surface, constructing a plurality of pillars on the top of the bottom surface, then placing concrete on the top and constructing the slab While constructing the building one layer at a time. At this time, the pillars and beams of the building (hereinafter referred to as “columns”) are constructed by embedding a plurality of reinforcing bars in concrete so that they have sufficient durability, earthquake resistance, compressive strength, tensile strength, and the like.

  Here, in order to construct the column, new reinforcing bars must be connected and connected to each reinforcing bar located on the upper surface of the slab. That is, the end of each reinforcing bar positioned on the upper surface of the slab. After each coupler is coupled to each coupler, a new reinforcing bar is placed on the upper side of each coupler, that is, after an operator places a new reinforcing bar directly or using a crane and is positioned on the upper side of the coupler. When the coupler is rotated, the end of the new reinforcing bar is inserted into the coupler and fastened, so that the reinforcing bar of the slab and the new reinforcing bar are connected and joined together. A new reinforcing bar is connected to each reinforcing bar.

  Next, after installing a plurality of hoops between the upper and lower parts of the reinforcing bars installed in a standing manner on the top of the slab, the reinforcing bars and the hoops are combined with a binding string and a plurality of hooks are connected. By joining the reinforcing bars, the construction of the reinforcing bar network for constructing the pillars of the building, that is, the reinforcing bar network in which the plurality of reinforcing bars, the hoops and the reinforcing bars are combined, is completed.

  However, in this conventional rebar network construction, in order to connect and connect each rebar of a slab and a new rebar, a crane or an operator directly stands a new rebar one above each rebar of the slab. Work to position, rotate the coupler in a state where the new rebar is supported by the crane, work to connect and connect each rebar of the slab and new rebar one by one, hoop and rebar to each rebar There is a problem in that work efficiency and workability are reduced due to many occurrences of work time, manpower, cost, etc. for constructing a reinforcing bar net because the work to be joined is done at a high place.

  In addition, the coupling work for connecting the hoop and the reinforcing bar to each of the raised reinforcing bars is performed at a high place, so that the worker can move or install a step structure such as a workable scaffolding and Not only does the work cost increase and workability decrease due to the addition of the work process to dismantle the step structure, but also due to carelessness of the operator, missing hands, or a step structure that is installed incorrectly when working at a high place. There was a high risk of safety accidents that caused workers to crash.

  Therefore, in order to solve this problem, the Korean Patent Registration No. 10-0863974 discloses a method of pre-assembling a reinforcing bar net for a reinforced concrete column. After arranging the muscles and the side muscles in the form of a column and installing a plurality of hoops and tie bars on the outer peripheral surface, the hoops and tie bars are connected to each reinforcing bar by fastening lines (not shown). After reassembling the rebar net, it was transferred to the place where the rebar net was to be installed using a crane and positioned on the upper part of the mounting rebar protruding from the upper surface of the bottom concrete, and then coupled to the mounting rebar Since the coupler is rotated so as to be moved to the reinforcing bar network side and the mounted reinforcing bar and the reinforcing bar net are coupled, the construction of the reinforcing bar net is completed.

  However, in the conventional method of assembling the reinforcing bar net for the conventional reinforced concrete column, each reinforcing bar and the hoop are coupled by a fastening line, and the reinforcing bar cannot be rotated by the fastening line. In order to connect each reinforcing bar of the mesh and the mounting reinforcing bar of the slab, the reinforcing bar of the reinforcing bar network is fastened by rotating the coupler connected to the mounting reinforcing bar, so that the reinforcing bar of the reinforcing bar network and the mounting reinforcing bar are Combined with each other.

  Here, the connection between the reinforcing bars of the reinforcing bar network and the reinforcing bars on the bottom concrete side is made by rotating the coupler, so that the crane lifts the reinforcing bar network until the connecting work between the reinforcing bars is completed. Since the state must be maintained continuously, it takes a lot of time, manpower, and cost to follow the rebar net construction work, and there is a problem that workability and work efficiency are lowered.

  And when the lengths of the reinforcing bars of the reinforcing bar net are different from each other, only a part of the reinforcing bars of the reinforcing bar net are fastened to the coupler, and among the reinforcing bars of the reinforcing bar network, the short reinforcing bars are It is not fastened to the coupler and is floating in the air, i.e., the short rebar cannot be connected to the mounted rebar by the rebar net only by the rotation of the coupler. There was a problem that the property, compressive strength, and tensile strength decreased.

  Further, since each reinforcing bar of the reinforcing bar net and the hoop and the reinforcing bar are connected by a fastening line, when the reinforcing bar net is raised by a crane, a phenomenon of twisting at the connecting part of each reinforcing bar and the hoop occurs. There is a problem in that the rebar mesh is twisted, and since the twisted rebar mesh cannot be restored to its original state, each rebar of the rebar mesh cannot be connected to and attached to the bottom concrete rebar.

Korean Registered Patent Publication No. 10-0863974 (2008.10.10.)

  The present invention has been proposed to solve the problems in the prior art as described above, and each reinforcing bar of the reinforcing bar net to be installed for constructing the column and the hoop are joined by a fixing clip. The main bars of the rebar net are rotated with the main bars of the rebar net being lifted and transported by the crane positioned at the couplers connected to the main bars of the slab. It is an object of the present invention to easily connect and connect the main reinforcing bars of the reinforcing bar network and the main reinforcing bars of the slab easily and fastened to the coupler.

  Further, by connecting an auxiliary coupler to a coupler connected to each main bar of the slab, the auxiliary coupler easily guides each main bar of the reinforcing bar network to the coupler, and of course, each main bar of the reinforcing bar network is connected to the auxiliary coupler. By separating the crane that has lifted the rebar net in the state where the end portion of the rebar is inserted, not only the work efficiency and workability according to the rebar net work are improved, but also the rebar with the crane separated. By rotating the main bars of the net and inserting and fastening the ends of the main bars of the reinforcing bar network into couplers connected to the main bars of the slab, all the main bars of the reinforcing bar network and the main bars of the slab can be connected together.

Transfer the rebar net to the main bar The connection of each main reinforcing bar of the reinforcing bar net and each main reinforcing bar of the slab is achieved by connecting each main bar end of the transferred reinforcing bar net to each main reinforcing bar of the slab via the coupler. A step of inserting, a step of separating the jig and the fixing base from the reinforcing bar network in which the ends of the main bars are respectively inserted in the auxiliary coupler, and the reinforcing bar network in which the jig and the fixing base are separated. Each of the main bars of the slab is connected to each of the main bars of the slab by inserting and fastening the main bars of the reinforcing bar network to the coupler connected to the main bars of the slab by rotating the main bars of the slab; Disassembling the auxiliary coupler from the coupler to which the main reinforcing bars of the reinforcing bar network are connected and coupled .

  According to the present invention as described above, the main bars of the rebar net to be installed for constructing the pillars are coupled to the hoops by the fixing clips, so that the main bars of the rebar net to which the fixing clips are coupled. Since each main bar of the reinforcing bar net that is lifted and transferred by the crane is positioned on a coupler coupled to each main bar of the slab, each main bar of the reinforcing bar network is rotated to rotate the main bar of the reinforcing bar network to the coupler. Since the ends of the main bars are inserted and fastened, the main bars of the reinforcing bar net and the main bars of the slab can be easily and easily connected to each other, and loss of time, manpower, cost, etc. in accordance with the reinforcing bar network construction work Of course, there is an effect of improving work efficiency and workability.

Thus, not only the above-mentioned main bars can be easily coupled, but also the reinforcing bar net is lifted with the end of each main bar of the reinforcing bar net inserted into the auxiliary coupler. By separating the crane from the reinforcing bar net, there is an effect of improving work efficiency and workability according to the construction work of the reinforcing bar net.

  At the same time, by rotating each main bar of the reinforcing bar net in a state where the crane is separated, the end of each main bar of the reinforcing bar net can be inserted and fastened to a coupler coupled to each main bar of the slab, Reinforcing bar main bars and slab main bars can be joined together, so the main reinforcing bar nets and slab main bars are completely maintained while maintaining the overall durability, seismic resistance, compressive strength, and tensile strength of the reinforcing bar network. There is also an effect of improving work efficiency and workability according to the joint work between the two.

  And, since the main bars and the hoops of the reinforcing bar net are connected by a fixing clip, when the reinforcing bar net is lifted by a crane, by preventing the phenomenon that the portion connecting the main bars and the hoop of the reinforcing bar net is twisted, Not only can the entire rebar mesh be twisted, but each rebar can be rotated by a fixed clip that connects each rebar to the hoop even if each rebar rebar and hoop is twisted in the process of lifting the rebar mesh. Therefore, the reinforcing bar network is restored to its original state, and the main bars of the reinforcing bar network are accurately positioned on the main bars of the slab, so that the connecting work between the main bars is very convenient.

The connecting connection between the main bars of the reinforcing bar network and the main bars of the slab is as follows.
Inserting each of the main bar ends of the transferred rebar mesh into the auxiliary couplers connected to the main bars of the slab via the couplers, respectively.
Separating the jig and the fixing base from the reinforcing bar network in which the ends of the main bars are respectively inserted into the auxiliary coupler;
Each rebar of the reinforcing bar net is inserted into the coupler coupled to each main bar of the slab by rotating each main bar of the reinforcing bar net from which the jig and the fixing base are separated, and each of the reinforcing bar nets Coupling the main bars to the main bars of the slab;
Disassembling the auxiliary coupler from the coupler to which the main bars of the reinforcing bar network are connected and coupled ;
A method for connecting and connecting reinforcing bar nets.
