Description

Structure improved steel bar connector

Technical field

The utility model relates to a kind of structure improved steel bar connector, relates to a kind of structure improved continued access device that is used for carrying out continued access between reinforcing bar and reinforcing bar especially.

Background technology

As shown in Figure 1, when on beam, building, be that reinforcing bar 2a is established in weldering between two reinforcing bar 1a in the past, behind the relative overlap joint of reinforcing bar 2a with two ends, 20a bundlees connection with steel cable again.Yet, overlap reinforcing bar 2a by this way and can make that girder construction intensity is lower, thereby need the continued access device that left and right internal thread constituted, and be respectively equipped with left external screw thread and right external screw thread in the end that two reinforcing bar desires of blocking engage, so that two reinforcing bars are firmly connected by the continued access device.

But, above-mentionedly make left and right external screw thread respectively at two steel bar ends, the mode that is spirally connected with continued access device again with left and right internal thread, because thread rotary orientation is not easy to construction mutually on the contrary, simultaneously, more because after steel bar end makes its external screw thread moulding by the processing of turning or other mechanical system, its external diameter is compared little with former reinforcing bar, and easily in external screw thread place residual stresses, so the joint of two reinforcing bars is difficult to bear the external force identical with the reinforcing bar body in fact, and very easily be subjected to destroy, like this, certainly will influence the structural strength of beam.

Novel content

Main purpose of the present utility model is to overcome above shortcomings in the prior art, and then a kind of structure improved steel bar connector that reinforcing bar and reinforcing bar are carried out continued access of being used for is provided.

To achieve these goals, the utility model provides a kind of structure improved steel bar connector, can comprise first fastener, and the one end is in order to be fixed on the described reinforcing bar, and the other end is provided with first threaded portion; Second fastener, the one end is in order to be fixed in the end of described reinforcing bar, and the other end is provided with second threaded portion, and described second threaded portion is relative with described first threaded portion; And length adjustment part, its two ends have the threaded portion respectively, and the thread rotary orientation of described threaded portion is identical, and one of them is long than another, and corresponding with described first and second threaded portion respectively, so that described length adjustment part is bolted between described first and second fastener.

When adopting the utility model that reinforcing bar and reinforcing bar are carried out continued access, can be spirally connected, and need not at the construction field (site), reach burden the site operation personnel thereby reduce follow-up processing to reinforcing bar car system thread in the identical mode of thread rotary orientation.

Embodiment

Below with reference to accompanying drawings, technology contents of the present utility model is described in detail, wherein, all accompanying drawings only provide reference and explanation usefulness, are not to be used for the utility model is limited.

Fig. 2, Fig. 3 and Fig. 4 are respectively three-dimensional exploded view, the three-dimensional combination figure of the utility model first embodiment and are applied to floor map between two reinforcing bars.The utility model provides a kind of steel bar connector of architecture advances, and it is applied between two reinforcing bars 1 reinforcing bar 2 is carried out continued access, and this continued access device 3 comprises first fastener 30, second fastener 31 and length adjustment part 32.

First fastener 30 can be sleeve, and the one end has weld part 300, carries out affixedly on the reinforcing bar 1 in order to be welded on, and its other end then is provided with first threaded portion 301.In the present embodiment, this first threaded portion 301 is an inner bolt hole.

Second fastener 31 also can be sleeve, and the one end has weld part 310, in order to be welded on reinforcing bar 2 free-ended ends, to be used for engaging with reinforcing bar 2 and to be that one, the other end of second fastener 31 then are provided with second threaded portion 311.In the present embodiment, second threaded portion 311 also is an inner bolt hole.

Length adjustment part 32 can be microscler rhabodoid, and its two ends have the identical threaded portion of thread rotary orientation 320,321 respectively, and wherein threaded portion 321 is longer than the length of another threaded portion 320; In the present embodiment, threaded portion 320,321 is an external screw rod, and between threaded portion 320,321, be formed with the portion of revolving 322 of holding, hold the portion of revolving 322 surfaces embossing (figure slightly) can be set, hold for the people and can be convenient to application of force rotation when holding the portion 322 of revolving, or order holds the portion's of revolving 322 external forms and is hexagonal shape (figure slightly), can pull the portion of revolving 322 of holding for instruments such as spanners.In addition, two threaded portions 320,321 of length adjustment part 32 are corresponding with the threaded portion 301,311 of above-mentioned first and

second fastener

30,31 respectively; In other words, the threaded portion 320 (external screw rod) of length adjustment part 32 is in the threaded portion 301 (inner bolt hole) that screws in first fastener 30, another threaded portion 321 (external screw rod) then screws in the threaded portion 311 (inner bolt hole) of second fastener 31, so that this length adjustment part is screwed onto between first and second fastener.

Like this, by above-mentioned contexture, can obtain the structure improved steel bar connector of the utility model.

Consult Fig. 4 and shown in Figure 5 in the lump, when desiring between two reinforcing bars 1 reinforcing bar 2 to be set, the weld part 300 of first fastener 30 is welded on the reinforcing bar 1, the weld part 310 of second fastener 31 then welds mutually with reinforcing bar 2 free-ended ends.Then, the threaded portion 320 that will screw in the length adjustment part 32 of second fastener 31 more in advance screws in towards first threaded portion 301, because identical and two threaded portions, 320, the 321 length differences of thread rotary orientation, therefore, after short threaded portion 320 screws in first threaded portion 301, long threaded portion 321 still has the enough length and second threaded portion 311 to be spirally connected, and then can reinforcing bar 1 firmly be connected with reinforcing bar 2 by this continued access device 3, as shown in Figure 6.

In addition, be illustrated in figure 7 as the three-dimensional exploded view of the utility model second embodiment.Wherein, length adjustment part 32 also can be microscler sleeve, and its two threaded portion 320,321 is an inner bolt hole, and first and

second fastener

30,31 then is respectively rhabodoid, and first and second threaded portion 301,311 is all external screw rod.

The above only is a preferred embodiment of the present utility model; these embodiment are used for limiting protection domain of the present utility model; therefore, the equivalent structure that all utilization the utility model manuals and accompanying drawing content are carried out changes, and all is included in the scope of the present utility model.
