Description

Rebar cap {Cap for Rebar}

The present invention relates to a rebar cap.

Rebar is a construction material that is extended in a bar shape and mainly provides tensile force, and is a mechanical structure that is very important in the fields of civil engineering and construction. In general, carbon steel is used as a material, and is mainly used when constructing a reinforced concrete structure together with concrete.

In general, when constructing a reinforced concrete structure, reinforcing bars are arranged and concrete is poured. Until the concrete casting is completed and the reinforcing bars are placed in the concrete, the reinforcing bars are exposed to the outside. Therefore, the safety of workers is threatened by the exposed reinforcing bars at the construction site of the reinforced concrete structure. For example, if a worker falls, there is a possibility that a human life accident may occur due to being stabbed at the end of an exposed reinforcing bar.

In order to solve this problem, various types of reinforcing bar caps have been developed, but there are problems in that it is not easy to combine and separate the reinforcing bars, and it is difficult to completely protect workers from the reinforcing bars due to structural weakness.

As shown in FIGS. 1 to 3, the reinforcing bar cap according to the present embodiment includes a base portion 110, a first extension portion 120 extending in one direction (A) from one end of the base portion 110, and a base portion. The second extension portion extends from the other end of the portion 110 to face the first extension portion 120, and extends from a predetermined point X toward one direction (A) so that the distance from the first extension portion 120 decreases. The main body 100 including 130, the first fastening part 200 formed to protrude from the first extension part 120, and the second fastening part 300 formed to protrude from the second extension part 130 include

The main body 100 serves to substantially surround the end of the reinforcing bar, is formed in a "c" shape as a whole, and may extend long in a direction (B) perpendicular to one direction (A). Therefore, the main body 100 can surround the ends of a plurality of rebars arranged side by side at once (see FIG. 2). Here, the main body 100 includes a base part 110, a first extension part 120, and a second extension part 130. Specifically, the base portion 110 may be formed in a flat plate shape and disposed to face the upper end of the reinforcing bar. In addition, the first and second extensions 120 and 130 are formed in a flat plate shape, the first extension 120 is disposed to face one side of the reinforcing bar, and the second extension 130 is the other side of the reinforcing bar. It can be arranged to face. As shown in FIG. 3, the first extension part 120 extends from one end of the base part 110 in one direction (A, for example, the downward direction), and at this time, the first extension part 120 extends in a straight line. It can be. In addition, the second extension part 130 extends from the other end of the base part 110 to face the first extension part 120, and the first extension part 120 moves toward one direction (A) from a predetermined point (X). It can be extended so that the distance between them decreases. That is, while the first extension part 120 extends in a straight line in one direction (A), the second extension part 130 is closer to the first extension part 120 in one direction (A) from a predetermined point (X). that can be extended. Therefore, the ends of the reinforcing bars can be inserted into the space between the first extension part 120 and the second extension part 130, and the first extension part 120 and the second extension part 130 have a relatively narrow gap. It may be fastened to the first and second fastening parts 200 and 300 in the region between the ends of the . Specifically, the second extension part 130 may include a 2-1 extension part 131 and a 2-2 extension part 133 . Here, the 2-1 extension part 131 extends from the other end of the base part 110 to a predetermined point X at a constant distance from the first extension part 120, and the 2-2 extension part 133 may extend from a predetermined point (X) toward one direction (A) such that the distance between them and the first extension part 120 decreases. That is, the second extension part 130 extends at a constant distance from the first extension part 120 from the other end of the base part 110 to a predetermined point X (the 2-1st extension part 131), It may obliquely extend from the predetermined point X so that the distance from the first extension part 120 decreases (the 2-2 extension part 133).

Meanwhile, the first extension part 120 may extend so that the distal end is farther apart from the base part 110 than the distal end of the second extension part 130 . That is, the end of the first extension 120 is disposed in one direction (A, downward direction) than the end of the second extension 130, and the first extension 120 is longer than the second extension 130. can be extended long. Due to this, it is easy to insert the reinforcing bar into the main body 100, and detailed information regarding this will be described later.

The first and second fastening parts 200 and 300 serve to fix the main body 100 to the end of the reinforcing bar, and the first fastening part 200 protrudes from the inner wall of the first extension part 120. and the second fastening part 300 is formed to protrude from the inner wall of the second extension part 130 . As such, since the first and second fastening parts 200 and 300 protrude from the inner walls of the first and second extension parts 120 and 130, when the reinforcing bar is inserted into the main body 100, the first and second fastening parts 200 , 300) may be fastened to both sides of the end of the reinforcing bar. At this time, the first and second fastening parts 200 and 300 are formed to protrude more as they get closer to the base part 110, and steps 200a and 300a are formed at the end (top) closest to the base part 110. do. The first and second fastening parts 200 and 300 may be fastened while the nodes of the reinforcing bars are caught on the steps 200a and 300a.

Specifically, the second fastening part 300 is formed at the end of the second extension part 130, and the first fastening part 200 may be formed closer to the base part 110 than the second fastening part 300. there is. That is, the first fastening part 200 and the second fastening part 300 may be formed at positions (different heights) that do not correspond to each other. The first and second fastening parts 200 and 300 are fastened to the node of the reinforcing bar. When formed at positions corresponding to each other (same height), the first and second fastening parts 200 and 300 are simultaneously fastened to the reinforcing bar, It can be difficult to connect to and separate from. However, since the first and second fastening parts 200 and 300 of the reinforcing bar cap according to the present embodiment are formed at positions that do not correspond to each other (different heights), the first and second fastening parts 200 and 300 are attached to the reinforcing bar one by one. It is fastened, so it is easy to connect and separate the reinforcing bars. 4A to 4E, when the reinforcing bar is inserted into the space between the first extension part 120 and the second extension part 130, after the reinforcing bar is fastened to the second fastening part 300 ( 4c), and may be fastened to the first fastening part 200 (see FIG. 4d). Therefore, the reinforcing bars can be easily fastened to the first fastening part 200 and the second fastening part 300 .

On the other hand, the main body 100 extends from the end of the second extension 130, and the third extension 140 extends so as to increase the distance from the first extension 120 toward one direction (A, downward). may further include. At this time, the first extension part 120 extends in a straight line in one direction (A), whereas the second extension part 130 is closer to the first extension part 120 in one direction (A) from a predetermined point (X). After the second extension part 130, the third extension part 140 extends away from the first extension part 120 in one direction (A). In this way, since the third extension part 140 extends away from the first extension part 120 in one direction (A, downward direction), there is a gap between the first extension part 120 and the third extension part 140. Since the spacing is relatively large, it is easy to insert the reinforcing bars into the main body 100 (see FIGS. 4A to 4B).

Meanwhile, the first extension part 120 may extend so that the distal end is farther apart from the base part 110 than the distal end of the third extension part 140 . That is, the end of the third extension 140 may be disposed in one direction (A, lower direction) than the end of the third extension 140 .

In this way, since the end of the first extension 120 is disposed in one direction (A, downward direction) than the end of the second extension 130 or the end of the third extension 140, the reinforcing bar is first extended in the first extension. After coming into contact with the inner wall of the part 120, it slides and is guided by the inner wall of the first extension part 120. As a result, the reinforcing bar can be naturally inserted into the space between the first extension 120 and the second extension 130 while being guided by the inner wall of the first extension 120 (see FIGS. 4A to 4E) . That is, in the process of inserting the reinforcing bar into the main body 100, the first extension part 120 may serve to guide the reinforcing bar.

Meanwhile, the second fastening part 300 may integrally extend from the inner wall of the third extension part 140 . In this case, inner walls of the second fastening part 300 and the third extension part 140 may be formed to be closer to the first extension part 120 toward the base part 110 . That is, the second fastening part 300 is extended while maintaining the inclined direction of the inner wall of the third extension part 140 (the inclined direction getting closer to the first extension part 120 toward the base part 110) as it is. Accordingly, the second coupling part 300 may protrude from the inner wall of the second extension part 130 having an inclination direction opposite to that of the inner wall of the third extension part 140 . Therefore, in the process of inserting the reinforcing bars into the main body 100, after the reinforcing bars come into contact with the inner wall of the third extension part 140 (see FIG. 4B), they can naturally pass over the second fastening part 300 (see FIG. 4b). see 4c). However, as shown in FIG. 3, the inclination D1 of the second fastening part 300 in one direction (A) is smaller than the inclination D2 of the third extension part 140 in one direction (A). can That is, the inclination of the second coupling part 300 may be smaller than the inclination of the third extension part 140 . Therefore, in the process of inserting the reinforcing bar into the main body 100, the reinforcing bar can easily ride over the second fastening part 300.

In addition, the second support part 420 may extend along the outer wall of the base part 110 in one direction (A) and in a vertical direction (B, a direction in which the main body 100 is extended). More specifically, the first support portion 410 is formed in plurality along a direction perpendicular to one direction (A) (B, the direction in which the body 100 extends long), and the second support portion 420 is the base portion 110 It can be formed long along the outer wall of. In this case, the first support part 410 and the second support part 420 may cross each other vertically. The main body 100 can structurally secure sufficient rigidity by the first and second support portions 410 and 420 .

In addition, as shown in FIG. 5 , in order to connect a plurality of main bodies 100 to each other, first and second coupling parts 500 and 600 may be formed in the main body 100 . Specifically, the first end 100a of the main body 100 and the main body 100 are connected to both ends of the main body 100 based on a direction perpendicular to one direction (A) (B, the direction in which the main body 100 is extended). It can be defined as the second end (100b) of. Here, the first coupling portion 500 may be formed at the first end portion 100a, and the second coupling portion 600 coupled to the first coupling portion 500 may be formed at the second end portion 100b.
