Problems solved by technology

The diameter of traditional straight thread connectors is less than 30mm, which can no longer meet the requirements of the development of the modern construction industry, and there are major safety hazards; most of the connections between steel bars use wire binding or electric welding, and the construction speed is slow and labor-intensive. Intensive, inefficient

Embodiment 1

[0009] Embodiment 1: refer to figure 1 , figure 2 , image 3 , the two ends of the screw rod of this embodiment have external straight threads respectively, and there are internal straight threads matching the external straight threads on the screw in the screw sleeve, and the external straight threads of the screw rod are screwed into the internal straight threads of the screw sleeve, and the matching The diameter of the internal straight thread and the external straight thread is 30mm-40mm. In this embodiment, the diameters of the two ends of the screw and the screw sleeve are the same and the direction of rotation is the same (see 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 is tapped with internal straight thread, and finally pressed at the construction site figure 1 The structure shown is alternately screwed to the screw and the screw sleeve with the same diam...

Embodiment 2

[0010] Embodiment 2: refer to figure 1 , figure 2 , Figure 4 , the two ends of the screw rod of the present embodiment have external straight threads respectively, and there are internal straight threads matched with the external straight threads on the screw rod in the screw sleeve, the external straight threads of the screw rod are screwed with the internal straight threads of the screw sleeve, and the two ends of the screw rod The direction of rotation of the outer straight thread is opposite, the inner straight thread of the screw sleeve is divided into two sections, and the direction of rotation of the two sections of the inner straight thread of the screw sleeve is opposite. The matching inner straight thread and outer straight thread have a diameter of 30mm-40mm. In this embodiment, the diameters at the two ends of the screw and the screw sleeve are the same and the direction of rotation is opposite (see Figure 4 ). This embodiment is suitable for occasions where...

Embodiment 3

[0011] Embodiment 3: refer to figure 1 , figure 2 , Figure 5 , in this embodiment, the diameters of the two ends of the screw and the screw sleeve are different and the direction of rotation is the same. The two ends of the screw rod of this embodiment have outer straight threads respectively, and there are inner straight threads matched with the outer straight threads on the screw in the screw sleeve, the outer straight threads at one end of the screw rod are larger than the outer straight threads at the other end of the screw rod, The inner straight thread of the screw is larger than the inner straight thread at the other end of the screw sleeve, the outer straight thread of the screw is screwed into the inner straight thread of the screw sleeve, and the diameter of the matching inner straight thread and outer straight thread is 30mm to 40mm. Compared with embodiment 1, this embodiment only has the outer straight thread of the screw rod at one end and the inner straight ...

Abstract

The invention relates to the technical field of building construction, in particular to a reinforcement end reinforced large-diameter straight thread connector for a reinforced concrete frame structure of a building and a connecting method thereof. The reinforcement end reinforced large-diameter straight thread connector comprises a screw and a screw sleeve; two ends of the screw are provided with an external straight thread respectively; an internal straight thread matched with the external straight threads on the screw is formed in the screw sleeve; the external straight threads of the screw are screwed with the internal straight thread of the screw sleeve; and the diameters of the internal straight thread and the external straight threads which are matched are 30 to 40 millimeters. The connecting method for the reinforcement end reinforced large-diameter straight thread connector alternately screws the screw and the screw sleeve with the same diameter and the same screwing direction in turn to make the screwing lengths of the screw and the screw sleeve meet the requirements of design and construction. The connector and the connecting method improve the tensile strength of reinforcement, reduce the potential safety hazard, greatly lighten the labor intensity of building constructors, improve the building construction efficiency, and have the advantages of convenient construction, stable quality, obvious economic benefit, convenience for field management, safe production and the like.

Description

technical field [0001] The invention relates to the technical field of building construction, in particular to a steel bar end reinforced large-diameter straight threaded connector of a reinforced concrete frame structure of a building and a connecting method thereof. Background technique [0002] With the increasing development of the modern construction industry, especially after a strong earthquake occurred in Wenchuan, Sichuan, my country on May 12, 2008 and caused heavy casualties and economic losses, all walks of life have raised concerns about the amount of steel connectors and steel bars used in traditional building concepts. , the diameter of the steel bar, and the density of the steel bar are questioned, which has attracted great attention from the construction industry. The above problems directly affect the construction quality, construction speed, economic benefits and construction safety of construction projects. The diameter of traditional straight thread conn...
