Description
Technical field
The utility model relates to building field Reinforcing Steel Bar In Reinforced Concrete Structure and connects, specifically a kind of different-diameter reinforcing bar connector.
Background technology
Steel Bars in Concrete Structure anchoring be connected very general, mechanical joining methods conventional is at present by end reinforced car silk to be connected, then utilizes screwed column type sleeve by two bar connecting.This method first needs to carry out cutting straightening to steel bar end oblique angle or non-straight portion, then in advance to needing the reinforcing bar connected to carry out car silk respectively, by turnbarrel, car silk braid cylinder half length is inserted in a wherein reinforcing bar, again by an other reinforcing bar alignment sleeve, Swiveling Rebar makes it to second half length of sleeve, thus reaches the object of bar connecting.This method car silk cut to lengthen difficulty, if car filament length is spent short, connecting reinforcement can not be tightened completely; If car filament length spends length, the partial threads exposed after connection reduces the bearing capacity of reinforcing bar, needs larger operating space Swiveling Rebar when mounted, and the method substitutes for second consolidation engineering reinforcing bar, and new-old concrete anatomical connectivity is all difficult to be suitable for, the reinforcing bar for different-diameter cannot connect.
Utility model content
For solving the above-mentioned deficiency of prior art, the utility model provides a kind of structure simple, and operation easier is little, and efficiency of construction is high, the different-diameter reinforcing bar connector that bar connecting mechanical property easily ensures.
A kind of different-diameter reinforcing bar connector, comprise steel bushing, screw rod, tooth line, described steel bushing has two sections of internal diameters differences and the hollow tubular structure be interconnected, the clean internal diameter of steel bushing is more bigger than bar diameter to be connected, the sidewall of described steel bushing is provided with multiple bolt hole corresponding with screw rod along its length, in the corresponding inserting bolt hole of screw rod, the inside wall of the corresponding bolt hole of described steel bushing is provided with tooth line.
Further, the clean internal diameter of steel bushing should 2mm larger than bar diameter.
Further, larger than bar diameter 8 ~ 10 times of described steel bushing length, the thickness of steel sleeve is not less than 5mm.
Further, described bolt hole is evenly arranged by spacing 25mm, and diameter of bolt hole is 13mm or 16mm.
The utility model is without the need to carrying out Qie Ping and the process of car silk to steel bar end, during installation, reinforcing bar is without the need to rotating, and action required space is little, and onsite application is convenient, and efficiency of construction is high, and bar connecting mechanical property easily ensures.

Fig. 2 is the lateral view of the utility model different-diameter reinforcing bar connector.
In figure: 1-steel bushing, 2-screw rod, 3-tooth line, 4-bolt hole, 5-reinforcing bar.
Detailed description of the invention
Below in conjunction with the accompanying drawing in the utility model, the technical scheme in the utility model is clearly and completely described.
As shown in Figure 1, the utility model different-diameter reinforcing bar connector comprises steel bushing 1, screw rod 2, tooth line 3, and described steel bushing 1 has two sections of internal diameters differences and the hollow tubular structure be interconnected, and the clean internal diameter of steel bushing 1 is more bigger than bar diameter to be connected.The sidewall of described steel bushing 1 is provided with multiple bolt hole 4 corresponding with screw rod 2 along its length, and in the corresponding inserting bolt hole 4 of screw rod 2, the inside wall of the corresponding bolt hole 4 of described steel bushing 1 is provided with tooth line 3, can ensure reinforcing steel bar bear reliable delivery.
During installation, first insert larger diameter reinforcing bar 5 until sleeve variable cross-section place, use torque spanner that screw rod 2 is screwed onto design load, then insert the less reinforcing bar 5 of diameter until prop up the reinforcing bar inserted, use torque spanner that screw rod 2 is screwed onto design load.Described steel bushing 1 length should be large 8 ~ 10 times of reinforcing bar 5 diameter and is advisable, and steel sleeve thickness must not be less than 5mm.Bolt hole 4 should be evenly arranged by spacing 25mm, and bolt hole 4 diameter preferentially selects 13mm or 16mm.
Fig. 2 is the lateral view that reinforcing bar connector of the present utility model is shown, the clean internal diameter of steel bushing 1 should 2mm larger than reinforcing bar 5 diameter, before reinforcement installation, should check that whether screw rod 2 screw thread is intact.The quantity of tooth line 3 can arrange a place or two places according to bar diameter.
The utility model different-diameter reinforcing bar connector is applicable to that rebar spacing is little, the situation of mechanically actuated insufficient space, execute-in-place comparatively ordinary cartridge joint efficiency also has and significantly improves, because the clean internal diameter of steel bushing is more bigger than bar diameter, without the need to carrying out Qie Ping and the process of car silk to steel bar end, during installation, reinforcing bar is without the need to rotating, and action required space is little, easy to use, efficiency of construction is high, and bar connecting mechanical property easily ensures.
The above; be only detailed description of the invention of the present utility model; but protection domain of the present utility model is not limited thereto; anyly belong to those skilled in the art in the technical scope that the utility model discloses; the change that can expect easily or replacement, all should be encompassed within protection domain of the present utility model.Therefore, protection domain of the present utility model should be as the criterion with the protection domain of claim.
