Description

Technical Field

[0001] This utility model relates to the field of building connectors, specifically to a rebar conversion connection device. Background Technology

[0002] Against the backdrop of the country's vigorous development of prefabricated buildings, the application of precast concrete components in prefabricated buildings is also increasing. However, due to factors such as complex construction site environments, insufficient component manufacturing precision, and the skill level of on-site construction personnel, the product quality and installation progress of prefabricated components are difficult to control, which in turn leads to an increase in the overall cost of prefabricated buildings.

[0003] The existing connection methods for precast components mainly have the following problems: 1. Traditional wet connection: the area of ​​post-cast concrete is large, the amount of on-site pouring is large, the anchoring steel bars in the joint area are numerous and complex, and there are difficulties in concrete pouring, which seriously affects the overall structural quality and safety of prefabricated buildings; 2. Sleeve grouting connection: there are problems such as incomplete grouting, difficulty in steel bar alignment, blockage of grouting holes preventing grouting, and high cost; 3. Dry connection such as bolts: the connection strength is weak, and the requirements for component manufacturing accuracy, on-site installation accuracy, and the technical level of construction personnel are high.

[0006] The adjustable rebar connection mechanism is connected to the first rebar and the second rebar at both ends via conversion joints; the adjustable rebar connection mechanism allows the axes of the first rebar and the second rebar to deviate within a preset range.

[0007] Preferably, the adjustable rebar connection mechanism includes a conversion sleeve, a connecting rod, an eccentric adjusting ring, a fixing nut, and a connecting cylinder;

[0008] The eccentric adjusting ring is provided with an elongated hole;

[0009] The main body of the connecting rod is a rod body, and a snap-fit ​​part is provided at one end of the rod body; the rod body of the connecting rod passes through the elongated hole of the eccentric adjusting ring;

[0010] One end of the conversion sleeve is connected to the conversion connector, and the other end is a sleeve structure that is connected to the fixing nut by threads. The fixing nut restricts the locking part of the connecting rod and the eccentric adjusting ring within the sleeve structure of the conversion sleeve. The rod body can slide within the elongated hole of the eccentric adjusting ring, and the eccentric adjusting ring can also rotate.

[0011] The end of the connecting rod without a locking part is connected to the adapter via a connecting cylinder.

[0019] 2) Radial deviation compensation is achieved through the elongated hole of the eccentric adjustment ring and the sliding structure of the connecting rod, breaking through the limitations of rigid connection in existing technology.

[0020] 3) The locking part of the fixing nut is precisely controlled to control the length of screwing in, preventing over-locking and failure of the adjustment function. Attached Figure Description

[0025] To make the objectives, features, and advantages of this utility model more apparent and understandable, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the embodiments described below are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0026] like Figures 1 to 3 As shown, a rebar conversion connection device is used to connect a first rebar 1 and a second rebar 2, including an adjustable rebar connection mechanism and a conversion joint 3;

[0027] The adjustable rebar connection mechanism is connected to the first rebar 1 and the second rebar 2 at both ends via conversion joints 3; the adjustable rebar connection mechanism allows the axes of the first rebar 1 and the second rebar 2 to deviate within a preset distance range.

[0028] Specifically, the adjustable rebar connection mechanism includes a conversion sleeve 4, a connecting rod 5, an eccentric adjusting ring 6, a fixing nut 7, and a connecting cylinder 8;

[0029] The eccentric adjusting ring 6 is provided with an elongated hole;

[0030] The main body of the connecting rod 5 is a rod body, and a snap-fit ​​part is provided at one end of the rod body; the rod body of the connecting rod 5 passes through the elongated hole of the eccentric adjusting ring 6;

[0031] One end of the conversion sleeve 4 is connected to the conversion connector 3, and the other end is a sleeve structure that is connected to the fixing nut 7 by threads. The fixing nut 7 restricts the locking part of the connecting rod 5 and the eccentric adjusting ring 6 within the sleeve structure of the conversion sleeve 4. The rod body of the connecting rod 5 can slide in the elongated hole of the eccentric adjusting ring 6, and the eccentric adjusting ring 6 can also rotate.

[0032] The end of the connecting rod 5 without a locking part is connected to the conversion connector 3 via the connecting cylinder 8.

[0033] As a further embodiment, the fixing nut 7 is provided with a protruding screw-stopping part, which is used to limit the length of the fixing nut 7 screwed into the sleeve structure, so that the fixing nut 7 can lock the locking part of the connecting rod 5 and the eccentric adjusting ring 6, while the eccentric adjusting ring 6 can still rotate freely.

[0034] As a further embodiment, the interface specifications of the conversion joints 3 at both ends of the adjustable rebar connection mechanism are consistent.

[0035] As a further embodiment, the two ends of the adjustable steel bar connection mechanism are connected to the conversion joint 3 by threads.

[0036] The adapter 3 has external threads, and the adjustable rebar connection mechanism has internal threads at both ends. The adapter 3 has a protruding mounting portion. This design facilitates installation and prevents over-screwing.

[0037] Conventional adjustable rebar connection mechanisms allow for a certain distance deviation between the axes of the first rebar 1 and the second rebar 2. However, for rebars of different diameters, different components need to be replaced. For example, in this embodiment, without the adapter 3, multiple specifications of adapter sleeves 4 and connecting sleeves 8 need to be manufactured to accommodate rebars of different diameters. In this invention, however, all components of the adjustable rebar connection mechanism do not need to be manufactured in multiple specifications to accommodate rebars of different diameters; only multiple specifications of adapter 3 need to be manufactured. The adapter 3 is simple to process, and if the specifications at both ends of the adjustable rebar connection mechanism are consistent, universal replacement can be made at both ends of the adjustable rebar connection mechanism to accommodate rebars of different diameters.

[0038] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
