- the anchor channel of the plate welding method according to the present invention corresponds to (e) of FIG. 4, compared to the case of the anchor channel of FIG. 1 according to the related art, the acupressure stress ⁇ is the smallest due to the geometrical feature. This can be seen from the description. Therefore, it is possible to understand more improved anchoring performance compared to the conventional anchor channel.
- FIG. 5 is a view for explaining the structural dynamic characteristics of the channel connecting portion of the anchor channel of the plate welding method and the anchor channel according to the prior art according to the present invention.
- the plate welded anchor channel 10 according to the present invention is more improved anchoring because the occurrence of deformation of the anchor portion 30 is coupled to the upper surface 24 of the channel significantly compared to the conventional anchor channel (Anchorage) Provides performance.
- FIG. 5A is a diagram showing that deformation such as a dotted line occurs on the upper surface 24 of the channel 4 due to the tensile force acting on the stem 2. Such a case corresponds to (a), (b), and (c) of FIG. 1 showing the anchor channel of the prior art.
- FIG. 5B is a diagram showing that deformation such as a dotted line occurs in the anchor head 3 due to a tension force acting on the stem 2. This case corresponds to Fig. 1 (d) showing the anchor channel of the prior art.
- Figure 5 (c) shows a portion of the anchor channel 10 of the plate welding method according to a preferred embodiment of the present invention, since the stem plate 40 and the channel 20 is coupled by direct welding method of Figure 5 It is a figure shown for comparison with the generation
- the anchor channel of the plate welding method according to the present invention since the anchor head is formed by welding the plate, the anchor channel formed through the rolling molding is more geometrically improved than the anchor channel according to the prior art. It has the advantage of being able to cope with small quantity and many kinds of products by being able to easily produce products of various specifications while showing the anchoring performance.
- the stem plate having holes when the stem plate having holes is applied to the anchor channel, the local pressure stress acting on the concrete from the anchor head is further lowered, thereby further improving the anchoring performance of the anchor channel. Therefore, the plate welded anchor channel can have the best effect in terms of anchoring performance in recent construction trends to connect more and more heavy and important facilities to concrete structures, but to improve safety.
- the anchor channel of the plate welding method according to the present invention can easily implement the production of stable welding quality and excellent performance and high production efficiency by the recent very advanced welding control technology and production automation technology.
