DETAILED DESCRIPTION

[0029] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0030] See also Figure 1-8The utility model embodiment discloses a high fault tolerance adjustable steel bar combination connector, which is used for connecting two adjacent steel bar skeleton components 1. The high fault tolerance adjustable steel bar combination connector includes: a connecting piece 2, an introduction piece 3, an adjustment piece 4 and a limit nut 5.

[0031] A first threaded section 6 is provided on the outer wall of the connecting member 2 , and a first threaded hole 7 is provided on the axis of the connecting member 2 .

[0032] The outer wall of the introduction member 3 is provided with a guide surface, and the axis of the introduction member 3 is provided with a second threaded hole 8 adapted to the first threaded section 6. The guide surface of the introduction member 3 can be an inclined plane or a conical surface.

[0033] The axis of the adjusting member 4 is provided with an introduction hole 9 and a third threaded hole 10 which are interconnected. The cross-sectional area of ​​the introduction hole 9 at the end away from the third threaded hole 10 is larger than the cross-sectional area at the end close to the third threaded hole 10. The introduction hole 9 is used to cooperate with the introduction member 3 to guide the connection between the connecting member 2 and the adjusting member 4. The third threaded hole 10 is adapted to the first threaded segment 6. Through the setting of the introduction hole 9, during the connection process of two adjacent steel frame members 1, the introduction member 3 can slide along the side wall of the introduction hole 9, and the extension direction of the third threaded hole 10 is located inside the introduction hole 9, so that during the connection process between the first threaded segment 6 and the third threaded hole 10, the first threaded segment 6 can smoothly enter the third threaded hole 10 and be threadedly connected with the third threaded hole 10 to realize the connection between the connecting member 2 and the adjusting member 4.

[0034] The limiting nut 5 is arranged at an end of the adjusting member 4 away from the connecting member 2 .

[0035] Among them, one of the connecting member 2 and the adjusting member 4 is threadedly connected to the end of one of the adjacent steel skeleton components 1, and the other of the connecting member 2 and the adjusting member 4 is threadedly connected to the end of the other adjacent steel skeleton components 1. The introduction hole 9 faces one end of the connecting member 2, and the introduction member 3 is connected to the first threaded segment 6. With the cooperation of the introduction member 3 and the introduction hole 9, the adjacent steel skeleton components 1 can be connected. The first threaded segment 6 is threadedly connected to the third threaded hole 10, and the limiting nut 5 contacts with the end of the adjusting member 4 to limit the adjusting member 4.

[0036] It should be noted that external threads are provided at the ends of two adjacent steel frame components 1, and the connecting piece 2 is threadedly connected to the external thread at the end of one of the two adjacent steel frame components 1 through the first threaded hole 7, and the third threaded hole 10 at the end of the connecting piece 2 away from the introduction hole 9 is threadedly connected to the external thread at the end of the other of the two adjacent steel frame components 1. The length of the first thread segment 6 is greater than the height of the introduction piece 3, so that the first thread segment 6 can have a certain screwing length with the third threaded hole 10. At the same time, when the first thread segment 6 is screwed with the third threaded hole 10, it can still be ensured that the third threaded hole 10 and its corresponding steel frame component 1 have a certain screwing length. During the connection process, the connecting member 2 is first connected to the external thread of one end of two adjacent steel frame components 1 through the first threaded hole 7, and the introduction member 3 is connected to the first threaded segment 6 of the connecting member 2 through the second threaded hole 8, and the third threaded hole 10 of the connecting member 2 away from the introduction hole 9 is connected to the external thread of the end of the other one of the two adjacent steel frame components 1. Under the guidance of the introduction member 3 and the introduction hole 9, the adjusting member 4 is screwed in the direction of the connecting member 2 so that the first threaded segment 6 of the connecting member 2 is connected to the third threaded hole 10 of the adjusting member 4, so as to realize the connection between the connecting member 2 and the adjusting member 4, and then realize the connection of the two adjacent steel frame components 1. A limit nut 5 is provided below the adjusting member 4. The limit nut 5 is provided so that after the adjusting member 4 is rotated to contact with the connecting member 2, or the connection length between the connecting member 2 and the adjusting member 4 reaches the connection required, the limit nut 5 is adjusted on the external thread at the end of the steel frame member 1 so that the limit nut 5 contacts with the adjusting member 4 to lock the adjusting member 4, thereby preventing the adjusting member 4 from loosening and affecting the connection strength of two adjacent steel frame members 1. With such a configuration, the ends of the two adjacent steel frame members 1 can ensure a reliable connection between the two adjacent steel frame members 1 within the allowable construction error, so as to achieve a fault-tolerant connection between the two adjacent steel frame members 1, thereby improving the on-site construction efficiency relative to the binding connection, and at the same time, when the steel frame member 1 is used as a vertical member, it can ensure a safe and reliable connection of the longitudinal force-bearing steel bars, thereby improving the longitudinal connection strength of the steel bars relative to the binding connection.

[0037] In a further embodiment, a connecting nut 11 is provided on one end of the first threaded section 6 away from the adjusting member 4, and the first threaded hole 7 extends from one end of the connecting nut 11 to the inside of the connecting member 2. The connection nut 11 is provided to facilitate the rotation of the connecting member 2 so as to connect the connecting member 2 to the external thread at the end of the steel frame member 1.

[0038] In a further embodiment, the first threaded hole 7 is arranged throughout the connecting member 2 along the axis of the connecting member 2. By arranging the first threaded hole 7 as a through-body structure, the screwing length of the external thread of the connecting member 2 and the end of the steel frame member 1 can be increased to a certain extent, thereby improving the connection strength of the connecting member 2 and the steel frame member 1.

[0039] In a further embodiment, there is a limiting boss at the junction of the introduction hole 9 and the third threaded hole 10, and the limiting boss is used to limit the introduction member 3. Through the action of the limiting boss, the introduction member 3 can be limited in the introduction hole 9; in a further optimized embodiment, a positioning component can also be provided between the inner wall of the introduction hole 9 and the outer wall of the introduction member 3, and the limiting component includes a matching positioning protrusion and a positioning groove, one of which is provided on the outer wall of the introduction member 3, and the other is provided on the inner wall of the introduction hole 9. The setting of the limiting component plays a limiting role when the introduction member 3 enters the introduction hole 9. At the same time, after the introduction member 3 completely enters the introduction hole 9, after the bottom end of the introduction member 3 contacts the limiting boss, when the adjusting member 4 is rotated, the adjusting member 4 drives the introduction member 3 to move along the first threaded section 6 toward the connecting member 2, that is, the second threaded hole 8 and the third threaded hole 10 have opposite threaded directions.

[0040] In a further embodiment, the shape of the adjusting member 4 is a hexagonal prism structure. The adjusting member 4 with a hexagonal prism shape is convenient for the adjusting member 4 to be rotated by a wrench. In other embodiments, the shape of the adjusting member 4 can also be set to other structures, as long as two relative limiting planes are set on its outer wall to facilitate the wrench to engage to realize the rotation of the adjusting member 4.

[0041] In a further embodiment, the height of the introduction hole 9 is equal to the height of the introduction member 3. This arrangement ensures that after the introduction member 3 is completely sunk into the introduction hole 9, the upper end of the introduction member 3 is flush with the upper end surface of the connecting member 2, and when the connecting member 2 and the adjusting member 4 are connected and in contact, the ends of the adjusting member 4 and the introduction member 3 jointly bear the axial pressure.

[0042] In a further embodiment, preferably, the introduction member 3 is a truncated cone structure, so that the introduction member 3 has an equal force at each circumferential position.

[0043] In this specification, each embodiment is described in a progressive manner, and each embodiment focuses on the differences from other embodiments. The same or similar parts between the embodiments can be referred to each other. For the device disclosed in the embodiment, since it corresponds to the method disclosed in the embodiment, the description is relatively simple, and the relevant parts can be referred to the method part.
