Embodiment 1

[0009] Embodiment 1: refer to figure 1 , figure 2 , image 3 . first to figure 2 The two ends of the shown screw are covered with external straight threads, and then the image 3 The screw sleeve shown in the figure taps out the internal straight thread, and finally at the construction site according to the architectural design requirements, several screws and screw sleeves are pressed figure 1 The structures shown are connected in sequence, and the interface between the two screws is roughly in the middle of the screw sleeve. figure 1 The connection method shown is one unit and has no limitation in three dimensions.

Embodiment 2

[0010] Embodiment 2: refer to figure 1 , figure 2 , Figure 4 . This embodiment is suitable for the situation that the two adjacent screws are inconvenient to rotate, and the same purpose as that of Embodiment 1 can be achieved only by rotating the screw sleeve. In this example, figure 2 Screw shown with Figure 4 The illustrated threaded sleeve with an undercut has opposite helix threads at both ends, and the threaded direction at one end of the screw rod is the same as the helical direction at one end of the helical sleeve. by figure 1 For example, as the left end of the left screw 1 is left-handed ( figure 1 Not given in), the right end is right-handed; then the left end of the screw sleeve 2 adjacent to it is right-handed, and the right end is left-handed.

Embodiment 3

[0011] Embodiment 3: refer to figure 1 , figure 2 , Figure 5 . This embodiment is suitable for connecting two screws with different diameters. Furthermore, there is no doubt that the screw rod and the screw sleeve in this embodiment can have the same helical direction as the screw rod and the screw sleeve in Embodiment 2.

Abstract

A strength straight thread connecting piece of concrete iron ends and connecting method are disclosed. Two ends of screw stem have outer straight thread. Coat has inner straight thread that matches with outer straight thread. The invention decreases the work force and improves the efficiency.

Description

Technical field: [0001] The invention relates to the technical field of building construction, in particular to a reinforcing bar end reinforced straight thread connector and a connecting method of a reinforced concrete frame structure of a building. Background technique: [0002] With the development of the construction industry, the amount of steel bars, the diameter of steel bars, and the density of steel bars are getting larger and larger. The connection method of thick-diameter steel bars has become the key to the design and construction of building structures, and directly affects project quality, construction speed, Economic benefits and construction safety. The traditional methods of connecting steel bars are mostly iron wire binding or electric welding. The above-mentioned methods are slow in construction, labor-intensive and inefficient. Invention content: [0003] The technical problem to be solved by the present invention is to provide a steel bar end reinforc...
