The present invention relates to a reinforcing bar connector of a prefabricated wall used to connect a reinforcing bar embedded in a prefabricated wall. More specifically, it is easy to use a reinforcing bar that acts as a seismic for up and down prefabricated walls. It is to provide auxiliary materials to make strong connection.

In particular, in the case of a high-rise building constructed by a prefabricated method, the reinforcing bars on the upper and lower floors meet each other by design or use, so that the connection of the reinforcing bars is difficult or difficult to exert sufficient functions as seismic reinforcing bars. It is intended to solve the given.

As is well known, when constructing a prefabricated building, reinforcing bars of seismic function are inevitably installed, and it is most desirable that the reinforcing bars installed on each floor are connected in a straight line. It is impossible for all layers to be completely straight by back.

However, it is possible to achieve sufficient function as seismic reinforcing bars and secure solid support of prefabricated walls by closely connecting reinforcing bars even under such errors.

For this purpose, the connection of reinforcing bars is conventionally performed as follows. The most common connection method is welding by connecting by welding, which exposes the following problems.

It includes excessive loss of time due to welding, large number of welding personnel, reliability of welding and thermal deformation due to welding.In case of shortening of work time, both upper and lower rebars are welded alternately rather than in situ usage. Not only could it be welded, but heat deformation occurred, which gave a great impediment to the durability of the building.

Another method is to tie up and down both bars with ties.

This caused more problems in maintaining the function and work than the above welding method, for example, loss of time, strength reduction, etc. In addition, the Utility Model Application No. 92-26536 (filed on December 26, 92) filed by the applicant No. 93-4124 (filed 9/9/93) and 93-18528 (filed 9/9/9), in which case the above problems are solved by using couplings, circular rings, and support bars. In case of using the coupling method, it is difficult to bind when the upper and lower rebars are shifted a lot.How to use the circular ring requires the manufacture of PC walls by inserting circular rings into the U-shaped reinforcing bars. There was a problem such as, when using the support bar, there was a problem such as cumbersome binding, the present invention has a purpose to solve such problems as described above. It is.

In order to achieve the object of the present application, the reinforcing bar of the prefabricated wall is a deformed bar or a number of irregular irregularities are formed at the end of the reinforcing bar, and the reinforcing bar is inserted into the insertion holder and the reinforcing bar and the space portion of the insertion holder. The concrete is firmly filled to reinforce the reinforcing bar and the support. The upper and lower support sections are bolted to form a connection between the reinforcing bars.

Therefore, even if there is a slight difference in the position of the upper and lower reinforcing bars, it effectively connects them to maintain the seismic function.

In addition, the present application can be easily installed by hand using support bars, bolts, nuts, etc. in the field, and after the installation, it is useful to be able to carry out various specifications without fear of deviation.

When described in detail with reference to the following preferred embodiments based on the accompanying drawings as follows.

Figure 1 is a configuration state diagram of the present invention, Figure 2 is an exploded state view of the present invention and Figure 3 is a cross-sectional view of the AA line of Figure 1, as shown in the cylindrical insertion into which the deformed tip of the reinforcing bar (2) is inserted Holder 11 is a high reinforcing steel bar 2 is in close contact with the stepped 113 at the inlet to form a predetermined space therein, the inlet hole 114 and the outlet hole (left and right) in the middle of the coupling holder 11 115 is perforated and integrally joined to the outer circumference of the coupling holder 11, and the support (1) formed of a connecting plate 12 of the flat plate in which the lateral holes 121 in the transverse direction are perforated, The coupling holder 11 of the support 1 is inserted into the reinforcing bar 2 and the concrete 4 is injected and fixed in the inner space so that the long holes 121 of the connecting plates 12 face each other. The bolt 13 having the washer 15 inserted into the long hole 121 is inserted through the nut 13 and inserted into the nut 13.

In the above configuration, the coupling holder 11 is more preferably penetrated by the screw bolt 112 so as to be penetrated into the screw bolt 112 from the outer circumferential surface thereof.

4 is an installation state diagram showing a state installed in the prefabricated wall of the present invention.

In this way, the main structure of the present application is to connect the reinforcing steel that is inevitably required to be installed in the so-called prefabricated building method (PC method) for each floor, so that a building having excellent durability and strength can be provided even if it is high-rise. When the reinforcing bar (2) of the protruding from the opening is replaced by inserting the front end of each of the reinforcing bar (2) into the coupling holder 11 is in close contact with the stepped portion 113 of the coupling holder 11 and the space inside When the concrete (4) is injected into the area through the inlet hole 114, the air is discharged through the discharge hole 115, and the internal space is filled with the concrete (4), and after the concrete (4) is solidified The coupling holder 11 of the reinforcing bar 2 and the support 1 is firmly fixed, and thereafter, the long hole 121 of the connecting plate 12 of the support 1 bound to the upper and lower reinforcing bars 2. ) Face the washers (15) Insert the silver bolt 13 and tighten with the nut 14 to make a strong coupling between the upper and lower reinforcing bars (2), especially in the above structure, even if the upper and lower reinforcing bars (2) slightly shifted (reinforcement bar when using assembly) Limit error is within 2 ~ 3mm) Material can be firmly joined by inserting washer 15 or perforated plate between upper and lower connecting plate 12 and by bolt 13 nut 14 It is a structure that can accommodate itself.

In addition, in the above structure, in particular, when a large load is applied between the reinforcing bar 2 and the support 1, a plurality of screw holes 111 are drilled in the joining holder 11 to connect the reinforcing bar 2 to the joining holder 11. After inserting and fixing into the screw hole 112, the concrete 4 is injected through the inlet hole 114 and grouted to be firmly supported even under a large load.

Therefore, the present application has all the characteristics that can provide a significant economic and durability improvement compared to the conventional binding method.
