Abstract

A rebar connector is disclosed which includes a first segmented member engageable with the first rebar, a second segmented member engageable with a second rebar and the sleeve for connecting the members together.

Description

Rebar connector

The present invention relates to a kind of rebar connector.

Commonly used piling technology in building trade generally comprises and makes a call to a stake hole, many is inserted in the hole with certain interval by the long reinforcing bar that reinforcing bar constituted that links together, then several steps such as cement injection in the stake hole.Because according to different geological conditions, a stake hole that has may be very dark, therefore usually needs many reinforcing bars are contacted one by one to be fixed up to form a continuous long reinforcing bar.

The process of piling sees also Fig. 1 a-1c, and (1), as shown in Figure 1a, equipment 10 is used to get a hole 20; (2), shown in Fig. 1 b, reinforcing bar 30 is inserted in the hole with certain interval, and reinforcing bar 32 links together in the junction, constitutes a long reinforcing bar; (3), shown in Fig. 1 c, behind these long reinforcing bar fix in position, the form of cement with cement paste 40 poured in the hole 20, thereby forms a concrete stake.

The existing technology that reinforcing bar 30 is connected together is that these reinforcing bars are tied together from the side.In order to carry out such connection, according to international standard, the overlap length between two reinforcing bars must equal 52 times of bar diameter.This will cause a large amount of wastes of material.

Also have much other methods that is used for connecting reinforcement.In a kind of method therein, reinforcing bar to be connected is crimped onto together by a curling adapter sleeve.But the shortcoming of this method need to be a coiled up device and to need very big operating space.Link together owing to usually need be in a limited space reinforcing bar be curled each other, therefore the range of application of this method is very limited.Another method is to add screw thread in the end of reinforcing bar, utilize a threaded adapter sleeve that two reinforcing bars are coupled together then, because in order to connect two reinforcing bars, the external threading of having to will be threaded earlier is connected on the reinforcing bar, and then an other reinforcing bar rotated in the cover that into is threaded, therefore very trouble operates.But also need to carry out tapping to end reinforced.The inventor proposed a kind of improving one's methods at this point, all screwed middleware inside and outside this method is utilized, and this middleware is attached on the every reinforcing bar to be connected.The above-mentioned cover of mentioning that is threaded can entirely be set on the middleware by screw thread, and twists back again, thereby is threaded with second middleware.The shortcoming of this method is, still needs reinforcing bar is carried out tapping, and will cause the raising of cost to the additional processing of reinforcing bar.

Therefore, the objective of the invention is to propose a kind of improved rebar connector.

According to an aspect of the present invention, propose a kind of rebar connector here, comprising: first link of the section of being divided into is used for being connected with one first reinforcing bar; Second link of the section of being divided into is used for being connected with one second reinforcing bar; An adapter sleeve is used for above-mentioned link is linked together.

Best described link comprises a groove that is used to hold the corresponding rib on the reinforcing bar at least, and the inside of described adapter sleeve has the screw thread that is used to be connected with the outside of described link.

Described connector can also be included in described link is connected to before the adapter sleeve, and with the device that all sections part of described link is fixed together, this device is preferably an O shape ring, or is other elastic components.

Describe the present invention below in conjunction with accompanying drawing.

Fig. 1 a-1c is used to represent that three of the concrete stake strengthened by reinforcing bar form the stage.

Figure 2 shows that the sectional view of the embodiment of the invention.

Figure 3 shows that parts explosion embodiment illustrated in fig. 2.

Fig. 2,3 illustrates the embodiment that is used for the connector of reinforcing bar connection of the present invention.This connector is marked by label 100, and is connected between first reinforcing bar 102 and second reinforcing bar 104 with the form of the middle connector 32 of Fig. 1 b.

Connector 100 comprise first a link 200a who is used for, be divided into section 102 that be connected with first reinforcing bar with one be used for, structure 104 that be connected with second reinforcing bar similarly, the also second parts 200b of the section of being divided into.As shown in Figure 3, first and

second link

200a, 200b comprise two

section part

202a, 204a and 202b, the 204b of semicircle column piece form respectively.Each section part all has a plurality of

groove

206a, 206b, is used to hold the rib 106 on the reinforcing bar.

And also has outer peripheral face groove 208a, a 208b on each

section part

202a, 202b, 204a, 204b.

O shape ring

300a, 300b can put into these grooves, are fixed on the reinforcing bar with the section part with two correspondences.

Have external screw thread 209a, 209b on the outer peripheral face of

parts

200a, 200b, and these screw threads are continuous between two corresponding semicircle column pieces.

Connector 100 also has the adapter sleeve 400 of a hollow cylinder.The inner surface 402 of this adapter sleeve 400 is provided with internal thread, is used for cooperating with external threaded surface 209a, 209b on parts 200a, the 200b.

In use, the both sides that the section part 202a of

parts

200a, 202b lay respectively at reinforcing bar 102, and groove 206a and rib 106 align.Then O shape ring 300a is set on the external threaded surface 209a of two section parts, enters among the groove 208a until it, thereby

section part

202a, 204a are fixed on the reinforcing bar 102.

Can parts 200b be fixed on second reinforcing bar 104 by same mode.

Then adapter sleeve 400 is threaded onto on the parts 200a, and it is screwed to the position of dotted line among Fig. 2.Parts 200b is aimed at adapter sleeve 400, adapter sleeve 400 is twisted get back to the position shown in Fig. 2 solid line then, thereby reinforcing bar 102,104 can be connected together.

The advantage of rebar connector of the present invention is and needn't carries out extra processing or reinforcing bar does not need extra action to reinforcing bar that the end that does not for example need to rotate reinforcing bar makes it to be connected with the cover that is threaded.The section part 202,204 can directly be attached on the reinforcing bar of existing structure, and by again be threaded the cover match, thereby reinforcing bar is connected together.

The above embodiment of the present invention is not determinate.For example, although the above-mentioned section form that part is two and half parts can be used a plurality of sections parts, and all sections part there is no need to hold the whole periphery of reinforcing bar, also can be part periphery for example.In addition, although adapter sleeve and link can connect by other connected mode between them by being threaded togather, for example adapter sleeve can be set on the link, and is then that they are welded together.In addition, although top with the section part with before adapter sleeve is connected, utilize 0 shape ring that the section part is fixed together, they also can be by operator's hand or other connected mode, for example bundlees by wire or fixing mode links together.
