[0002] During the main structure construction phase of a building, steel bar tying is particularly important. The traditional steel bar tying overlap method is to ensure that the overlap length meets the design requirements, and the steel bar tying spacing is arranged by feeling. Although there are quality management personnel on site to check, it is still easy to have the tying spacing be too large or too small, or even miss a tie.

[0003] The existing application number is 201320102449.X, which is a non-destructive lap joint device for steel bars, comprising a U-shaped lock buckle, a gusset plate and a bolt. The upper part of the U-shaped lock buckle is threaded to form a threaded section, the gusset plate penetrates the threaded section of the U-shaped lock buckle, and the gusset plate is provided with a bolt that matches the threaded section. Although the non-destructive lap joint device for steel bars can meet the requirements for lap joint fixation of steel bars, it can only press the steel bars tightly together, and cannot meet the requirements for lap joint spacing, resulting in poor final lap joint quality.

[0007] As a further improvement of the above technical solution:

[0008] The spacing adjustment mechanism comprises an adjustment screw rod, which is movably arranged in two overlapping plates, and an adjustment nut is arranged on both sides of each overlapping plate.

[0009] One end of the adjusting screw is provided with a screwing portion.

[0010] The spacing adjustment mechanism includes an adjustment screw, which is inserted into two lap plates, threadedly connected to one lap plate, movably sleeved to the other lap plate, and respectively arranged on adjustment nuts on both sides of the lap plate.

[0011] The clamping mechanism comprises a first hoop body and a second hoop body, the outer side of the first hoop body is fixed on the lap plate, one end of the first hoop body and the second hoop body are hinged, and the other end is connected by a locking piece.

[0012] The first hoop body and the second hoop body are both arc-shaped.

[0013] The axis of the first hoop body extends along the length direction of the lap plate.

[0014] The first hoop body is welded to the lap plate.

[0015] The locking element is a locking bolt.

[0016] The overlapping plates are square in shape.

[0017] Compared with the prior art, the advantages of the utility model are:

[0018] When the steel bar lap joint device of the utility model is used, each clamping mechanism on one lap joint plate is clamped to one steel bar, and each clamping mechanism on another lap joint plate is clamped to another steel bar; the spacing between the two lap joint plates is adjusted by each spacing adjustment mechanism so that the two steel bars meet the lap spacing requirement.
