Description

The new reinforcing steel bar connector

Technical field

The utility model relates to the building machinery field, and specifically, the utility model relates to a kind of new reinforcing steel bar connector that reinforcing bar connects that is used for.

Background technology

The length of reinforcing bar is generally between 6 meters to 9 meters, and during actual building operations, a lot of situation reinforcing bar length is arranged more than tens meters, so just the reinforcing bar more than two need be coupled together to reach the building operations requirement.Traditional method of attachment is to adopt overlap welding or butt welding, because high-temperature soldering diminishes reinforced steel bar strength, and welding quality also can't guarantee, and material, time-consuming is taken a lot of work, taken in welding.

What existing improved technology adopted is to adopt threaded sleeve that two end bars are coupled together, and so just need go out screw thread at the end reinforced car of needs connection, processes difficult like this, and the thread quality that processes can't guarantee.When reality was used, bonding strength was not enough, often breaks away from, and this tends to cause waste owing to screw thread fragile causing in transportation, also can't guarantee construction quality.

At the deficiency that above prior art exists, the special the utility model that proposes.

The utility model content

For realizing above-mentioned utility model purpose, the technical scheme of reinforcing bar connector provided by the utility model is: a kind of new reinforcing steel bar connector, comprise that butt joint encases two semicircle branch sleeves of reinforcing bar, the branch sleeve diameter is greater than bar diameter, branch sleeve two ends after the butt joint are truncated cone shape, and there is screw thread on the surface; The branch sleeve two ends cooperate respectively and are equipped with pulloverly, and pullover is hollow tube-shape, the truncated cone shape of pullover cavity for matching with the branch sleeve both ends and installing, and the cavity inner surface has the retaining screw thread.

The both ends of the surface tapering of described branch sleeve butt joint postforming grade is less than the tapering of cavity in pullover.

The inner surface of described each semicircle branch sleeve is provided with and the staggered rib that cooperates of screw thread steel, is provided with sawtooth between the described rib.

The taper seat at described branch sleeve two ends is the straight line conical surface or the arcuation conical surface; Described pullover cavity is and the corresponding straight line conical surface of sleeve two ends shape or the arcuation conical surface.

Described pullover external surface is a hex nut.

The tapering α of the taper seat at two ends, described two semicircle branch sleeve butt joint backs is 5-65 °; The tapering β of described pullover cavity is 5-65 °.

The tapering α of the taper seat at two ends, described two semicircle branch sleeve butt joint backs is 8-45 °; The tapering β of described pullover cavity is 8-45 °.

The tapering α of the taper seat at two ends, described two semicircle branch sleeve butt joint backs is 12-30 °; The tapering β of described pullover cavity is 12-30 °.

The tapering α of the taper seat at two ends, described two semicircle branch sleeve butt joint backs is 8 °; The tapering β of described pullover cavity is 12 °.

The beneficial effects of the utility model are: the utility model is applicable to the connection of reinforcing bar, the bonding strength height, and stability is strong, processing is simple, and is with low cost, easy for installation, be fit to very much the construction site Fast Installation, saving of work and time has higher utility and promotion prospect.

Below in conjunction with accompanying drawing the specific embodiment of the present utility model is described in detail.

The specific embodiment

Fig. 1 is the assembling schematic diagram of the utility model reinforcing bar connector embodiment 1, Fig. 2 is Fig. 1 user mode figure, as shown in Figure 1, 2, the utility model reinforcing bar connector comprises that butt joint encases two semicircle branch sleeves 2 of reinforcing bar 1, branch sleeve 2 diameters are greater than reinforcing bar 1 diameter, branch sleeve 2 two ends after the butt joint are truncated cone shape, and there is screw thread 3 on the surface; Branch sleeve 2 two ends cooperate respectively that to be equipped with pullover 4, pullover 4 be hollow tube-shape, the truncated cone shape of pullover 4 cavitys for matching with branch sleeve 2 both ends and installing, and the cavity inner surface has retaining screw thread 5.

The both ends of the surface tapering α of branch sleeve 2 butt joint postforming grade is less than the tapering β of pullover 4 interior cavitys; The tapering α of the taper seat at two ends, two semicircle branch sleeve 2 butt joint backs can choose at 5-65 °; The tapering β of pullover 4 cavity can choose at 5-65 °; Preferable technical scheme is that α chooses between 8-45 °, and β also chooses at 8-45 °; Preferably α is between 12-30 °, and β is between 12-30 °.In the present embodiment, α is 8 °, and β is 12 °

Fig. 3 is the structural representation of branch sleeve among Fig. 1, Fig. 4 be among Fig. 3 A to view, Fig. 5 be among Fig. 3 B to view, shown in Fig. 3,4,5, the inner surface of each semicircle branch sleeve 2 is provided with the screw thread 6 staggered ribs 7 that cooperate with reinforcing bar 1 external surface, is provided with sawtooth 8 between the rib 7.

The taper seat at branch sleeve 2 two ends is the straight line conical surface or the arcuation conical surface, and pullover 4 cavity is and the corresponding straight line conical surface of sleeve two ends shape or the arcuation conical surface.The straight line conical surface that present embodiment adopts.

Fig. 6 is a lateral view pullover among Fig. 1, goes out as shown in Figure 6, and pullover 4 external surface is a hex nut.

When actual installation is used, reinforcing bar 1 end part aligning that two ends need be connected, then two semicircular branch sleeves 2 are placed on the junction, rib 7 in the branch sleeve 2 embeds the screw thread 6 of reinforcing bar 1 external surface, then with pullover 4 two side ends of being inserted in branch sleeve 2 respectively, with the mutual opposite spin of spanner, utilize the retaining screw thread 5 in pullover 4 to tighten with the screw thread 3 of branch sleeve 2 external surfaces, though because alignment between the branch sleeve 2, so leave one section space, so pullover 4 during gradually to branch sleeve 2 middle part displacements, constantly push the conical surface of branch sleeve 2, final state is that sawtooth 8 contracts on the rib 7 are gone into the surface of reinforcing bar 1, has so just formed very firm connection, has reached the effect of one integrated mass.

The utility model also can have other variation; as well known to the skilled person; the foregoing description only plays the exemplary role in the above-mentioned utility model protection scope; for those of ordinary skills; also have a lot of conventional distortion and other embodiment in the protection domain that the utility model limited, these distortion and embodiment will be within the protection domains that the utility model awaits the reply.
