Description of the invention (2) Mechanical structure ’However, if there is a sudden structure in the mortar and hardening treatment, a fragile structure may occur. In order to solve this problem, there is a mechanical connection method called um u + ， ^, which is referred to as an upsetting method (upsetting) has been proposed. This side of our factory ‘,, " end tile end part heating 'is then forged in the axial direction. However, 'this method causes material loss due to shortening the length of the slub steel bars. In addition, since the heating is performed only at the connection end, the structure of the material changes with and without heating, which causes a problem that the elongation becomes small. Due to the heating of the part, the connection end part is weakened during impact, and the structure is irregularly distributed: In order to solve this problem, another cold treatment method, which is different from the above method, is generated. This method uses high pressure in the axial direction of the bamboo reinforcement to forge the connection end part at normal temperature, as shown in Figure 5. In processing, the first method forms a cutting thread at the connection end portion, and the second method is to form a rolled thread after the cutting process for skimming the slag due to damage to the connection end is completed. The first method, Techniport SA has been developed and disclosed in Korean Patent Publication No. 94-831 1 and US Patent No. 5, 1 5 8, 5 27. The second method was developed by the British CCL and disclosed in British Patent No. 2,286,782A. However, the 'bamboo reed's bar undergoes work hardening, which results in a very high tensile strength and hardness and a rapid decrease in impact energy absorption.

It can be found that the ferrite and peralite structures in FIG. 7A grow long and continuous in the axial direction, while the metallographic structure shown in FIG. 6A shows orthogonality, respectively. After upsetting and forging, the axial structure of the material and the original material. According to the 7B image, it can be found that the ferrite and peralite tissues are uniformly distributed; the "metallographic structure of the part after the forging process in the figure" is very non-convex. From here The structure after forging is irregular. SUMMARY OF THE INVENTION In order to solve the above problems, the object of the present invention is to provide a thread for reinforcing concrete manufactured at the joint end of a bamboo reinforcement, and to connect the structure with the bamboo reinforcement by this method & gt In addition, the present invention can also be used to manufacture the joints and joints of bamboo reinforcements in the present invention to achieve the following purposes: ^ 1. Without cutting treatment, it can maintain the existing fibrous structure; 2. No need The forging process deals with 'reinforcing structural weaknesses due to workpiece hardening; in order to understand this' according to the present invention, a method for manufacturing a bamboo-steel rebar connecting end for strengthening concrete is characterized by swaging, (swag i ng) steps, and bamboo joints. The ribs and nodes of the steel bar are swaged at room temperature. Depending on the degree of manufacture, the maximum diameter of the connecting end is slightly larger than this bamboo steel.

Figure 1A illustrates the pre-manufactured reinforced concrete reinforced concrete slub rebar. The slub rebar (100) is composed of a cylinder (10), and the ribs (30) and nodes (20) around the outside are formed at equal distances. In addition, depending on the length of the reinforcing bar, the connecting end portion (40) related to the middle portion of the reinforcing bar may be normally bent. Figure 1B shows the swaging process. At normal temperature, a steel bar is inserted into a die consisting of two or more pieces or rollers using hydraulic or mechanical forces (front and side views are shown in Figures 8A and 8B, respectively). For swaging. Figure 1A shows that the projected ribs of the connecting end part (40) and the nodes are stamped and the bamboo rod steel bars (100) have the same diameter (11) as the cylinder. 'In this method, the central axis of the cylinder and the central axis of the forged part are concentric.

Description of the invention (7) The treatment is similar to that of Fig. 1C ', the plane is cut by plane cutting and chamfering, and the edges around this section are cut into planes. FIG. 1E shows a state in which the bamboo reinforcement is processed and modified. In this way, the fixing force of the bamboo reinforcement can be improved when the bamboo reinforcement is treated to prevent the thread ^ corners from being damaged *. And the threaded portion (60) formed by the outer peripheral surface of the rolled swaging portion (50) is similar to that shown in Fig. 1E. In addition, the outer diameter (61) of the rolled threaded portion (60) formed is equal to or slightly larger than the diameter (11) of the cylinder (10). … In this way, the metallographic structure of the threaded portion of the material according to this invention is not cut, and the threaded portion can be manufactured according to plasticity, which can improve the mechanical strength, and the metallographic = structure becomes denser, while maintaining the existing structure inside the connecting end Therefore, this connection end can withstand large loads and impacts. 6M and 3B show a photo of a connection end structure according to the present invention, and FIG. 3A is a metallographic diagram of the axial direction of the bamboo reinforcement. The continuity with the Plei iron structure appears more clearly and the structure becomes tighter. Fig. 3B is a metallographic structure diagram of the bamboo rebar orthogonal to the axial direction. The result is closer than that of Fig. 7B. For example, we can manufacture different types of threads, such as ring-shaped gravel double or triangular threads, and each other can be manufactured. The production of ring-shaped threads is better. For example: Figure 2 A and Figure 2B show the threads that can be manufactured. Edge = = pattern production: the thread of the thread is not raised, and at the same time, the fixing force is enhanced, and the thread is thickened in the full-cut silver, so the resistance is strong, and if not only

Although 'shown in FIG. 1A as a reinforced concrete ribbed (300) and node (20) reinforced concrete slub rebar (100), the present invention is not limited to this slub rebar can also be formed by diagonal lines or X-shaped lines . ^ Figure 4 shows the method described above for forming reinforced concrete to connect different bamboo rebars. This uses a coupler (200) with a nut (Figure 4β, 4C) 'in each different bamboo rebar (100) The connecting end is formed into the shape of the rolled thread portion (60), and the rolled thread portion (60) is connected by coupling. 8A and 8B respectively show a front view and a side view of a cylindrical body, in which a deformable rod—inserted into the deformable rod 2 and composed of two or more pieces or a roller system, and then the hydraulic pressure or driving force is used to make Used in this deformable rod, the protruding rib portion 6 or the node 4 of the connecting end portion 8 can be pressed in so that its diameter is substantially equal to the diameter of the deformable rod 2. As described above, according to the present invention, at the construction or civil engineering site, for strengthening concrete, the joint end of the bamboo reinforcement can be manufactured without damaging the steel structure of the joint end, and the mechanical strength of the joint end can be enhanced. In addition, ‘this connection end can be made by swaging die and rolling, so construction will be easier’ and the construction cost can be reduced accordingly. In particular, the connection
