The present invention is a simple and robust connection between upper and lower reinforcing bars among reinforcing bars that are purchased for seismic use in all assembly walls when constructing multi-family houses such as high-rise buildings or apartment townhouses by the prefabricated construction method. It relates to a reinforcing bar connector of a prefabricated wall to improve the function of the rebar.

In general, the biggest influence on the construction period during the construction of high-rise buildings is the curing of the poured concrete, because the construction of the concrete is carried out on each floor by placing the formwork on the reinforcing steel and steel structures. One of the shortening methods is the prefabricated method, which assembles the cured wall according to the design according to the design, thus eliminating the need for concrete curing, which shortens the air.

However, the most problematic problem in the prefabricated construction method is the coincidence installation of the upper and lower walls, which can not tolerate some errors due to the characteristics of the reinforced concrete prefabricated walls. A little shift between days is common.

However, if possible, the rebars in each floor should be in a straight line, so the connection between the rebars is easy and the functions such as strength reinforcement and seismic action of the building can be sufficiently exerted, but as described above, some errors are common. The present invention is designed to provide a connector between reinforcing bars that can fully function even under such slight errors.

Conventionally, connection of reinforcing bars is generally 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 working time, both upper and lower rebars are welded alternately rather than in-situ welding. Not only were they not sufficiently welded, but there was also a heat deflection which gave a great impediment to the durability of the building.

Another method is to bundle up and down rebar with tie lines.

This caused more problems in maintaining the function and working than the above welding method, for example, loss of time, reduced strength, etc. In addition, the Utility Model Application No. 92-26536 filed on December 12, 2008 ), 93-4124 (filed on March 9, 993), and 93-18528 (filed on 93.9.16, etc.). In these cases, the above problems can be solved by using couplings, circular rings, and support bars. In case of the coupling method, it is difficult to bind when the upper and lower reinforcing bars are shifted a lot, and the circular ring method requires the manufacture of PC walls by inserting circular rings into U-shaped reinforcing bars. There was a problem such as damage, and when using the support bar, there was a problem such as troublesome binding, the present invention is to solve the above-mentioned problems. Neunda.

In order to achieve this purpose, the present application combines 2 ~ 4 holding plates at the ends of upper and lower reinforcing bars, inserts c-angles into angle holes of upper and lower holding plates, and fastens them with nuts to connect structural reinforcing bars easily and firmly. I would have to.

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, in the field of the present application, it can be easily installed manually by using a support tool, an angle, a nut, etc., and after the installation, it is also useful to be able to carry out various standards 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, the present invention as shown in the center is an arc portion 111 and both ends are The flat portion 112 is formed in the center of the flat portion 112, the angle hole 113 is drilled, and 2 to 4 sets are combined (the drawing shows only an example in which 2 sets are combined). Angle tab is formed of a holding plate (11) forming a cylinder that the reinforcing steel (2) is inserted closely, the U-shaped circular bar inserted into the upper and lower angle holes 113 at the same time and fastened with nuts 14 at both ends. It is composed of a c-shaped angle 12 having a (121).

It is preferable to form a plurality of irregularities on the inner surface of the arc portion 111 of the holding plate 11 of the above configuration.

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 bars that are 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 3) protrudes from the opening and is replaced, the tip of each of the reinforcing bar 2 is closely packed so as to enclose the arc 111 of the holding plate 11, and the arc 111 is 180 가. The arc is composed of two holding plates 11 and the arc portion 111 is formed of three holding plates 11, and the arc portion 111 is formed of four holding plates 11 having an arc of 90 degrees. The holding plate 11 of each pair is a flat plate 112 and the angle hole 113 to pass through each other in this state, the c-angle is inserted into the upper and lower angle holes 12 in this state and the angle Insert the washer 15 into the tab 121. The coupling is completed filled with a main surface and a nut (14).

In particular, even in the above structure, even if the upper and lower reinforcing bars 2 are slightly shifted (the marginal error of the auxiliary bar when assembled and used is within 2 to 3 mm), since the angle angle 12 can be easily combined, the material error can be easily accommodated. It is a preferable structure that can be.

In addition, the concave-convexities in the inner surface of the circular arc portion 111 of the holding plate 11 in the above structure, the friction between the holding plate 11 and the reinforcing bar (2) is raised to enable a solid support.

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