Abstract
The utility model provides a steel connector with a pretensioner; the steel connector comprises a sleeve, a fixture block, a nipple, a baffle ring and a spring; wherein the two sleeves are respectively screwed with the external diameter of the nipple by the screw threads of the internal holes at the tails of the two sleeves; the external screw threads of the nipple are respectively the left screw thread and the right screw thread; the internal screw threads of the two sleeves which are screwed with the nipples are also respectively the left screw threads and the right screw threads. The shapes of the sleeves are cones; a stop block is provided in the sleeves; two semi-cone fixture blocks are provided in each sleeve; pawls are provided inside the fixture blocks. A baffle plate which is linked with the inner cavity of the nipple as a whole is provided in the middle of the inner cavity of the nipple, which make the cavity of the left sleeve and the cavity of the right sleeve are separated and are respectively sealed. The spring is provided between the tail of fixture block in the cavity of the sleeve and the baffle ring; the baffle ring is blocked on the stop block. The steel connector sleeve can connect two steel bars together tightly so that the connector will not be cracked or drop off even if the steel bars are stretched to snap. The steel connector can be widely used when the steel bars are needed to be connected together and used in reinforced concrete constructions.
Description
Technical field:
The utility model provides a kind of reinforcing bar connector, and a kind of reinforcing bar connector that has pre-tightening apparatus particularly is provided.
Background technology:
In reinforced concrete construction, have a large amount of reinforcing bars to need to connect, the connection of reinforcing bar now mostly is to use the electric welding technology to solve, because the welding inconvenience of field or high-building construction, and the restriction of other technical condition, can not guarantee being perfectly safe of reinforcing bar connection.
Summary of the invention:
The utility model provides a kind of reinforcing steel bar connecting sleeve tube that has pre-tightening apparatus, utilize this reinforcing steel bar connecting sleeve tube to link together two reinforcing bars securely, also can not ruptured or come off even reinforcing bar breaks its bindiny mechanism, this reinforcing steel bar connecting sleeve tube needing can be widely used in the occasions such as reinforced concrete building of connecting reinforcement use.
The reinforcing bar connector that has pre-tightening apparatus that the utility model provides, it is by sleeve, fixture block, to silk, baffle ring, compositions such as spring, two sleeves screw by the screw thread of afterbody endoporus separately and screw thread to the silk external diameter respectively and connect, external screw thread to the silk both sides is respectively left hand thread and right-handed thread, with silk is screwed two internal thread of sleeve that connect, also be respectively left hand thread and right-handed thread, it is tapered that sleeve configuration becomes, be provided with limited block in the sleeve, be placed with two half cone type fixture blocks in each sleeve, the fixture block inboard is provided with pawl, to a dividing plate that combines as a whole with inner chamber is arranged in the middle of the silk inner chamber, make left, each self-enclosed independence of right sleeve chamber is provided with spring between fixture block tail end and the shelves ring in the sleeve chamber, the shelves ring is stuck on the limited block.
The reinforcing bar connector that has pre-tightening apparatus that the utility model provides, in use, reinforcing bar imports reinforcing bar connector along tooth, the steel bar end of insertion end withstands on the dividing plate in the silk inner chamber, because the effect of taper effect, two springs are oppressed two corresponding fixture block tail ends respectively, make the pawl and the reinforcing bar obvolvent of two corresponding fixture blocks, when screwing to silk, the dividing plate of silk is oppressed reinforcing bar to outer displacement, just be subjected to the effect of interlock of fixture block pawl and taper effect, make the pawl of two symmetrical fixture blocks shoot reinforcing bar, thereby make it more firm, can not become flexible.Have the both sides symmetry of the reinforcing bar connector of pre-tightening apparatus, structural principle is identical.The stressed sleeve of giving of fixture block, under the situation of sleeve tensile strength greater than reinforcing bar tensile strength, the reinforcing bar connector that has pre-tightening apparatus can be not destroyed.
The reinforcing bar connector that has pre-tightening apparatus that the utility model provides, utilize this reinforcing bar connector, can link together two reinforcing bars securely, avoided because the reinforcing bar that human factor causes connect not firm because of, also brought safer construction environment simultaneously to the job site.
Description of drawings:
Fig. 1 has the reinforcing bar connector assembling schematic diagram of pre-tightening apparatus.
Fig. 2 has in the reinforcing bar connector of pre-tightening apparatus the front view to silk.
Fig. 3 has in the reinforcing bar connector of pre-tightening apparatus the sectional view to silk.
Fig. 4 is the A-A sectional view among Fig. 1
Fig. 5 has the front view of the middle-grade ring of reinforcing bar connector of pre-tightening apparatus
The specific embodiment:
Further specify below in conjunction with embodiment and accompanying drawing.
1 reinforcing bar among the figure, 2 fixture blocks, 3 (7) sleeves, 4 springs, the 5 pairs of silks, 6 dividing plates,
8 pawls, 9 baffle rings, 10 limited blocks, 11 (12) external screw threads.
The utility model provides an embodiment of the reinforcing bar connector that has pre-tightening apparatus, by accompanying drawing as can be known, it is by sleeve 3, fixture block 2, to silk 5, baffle ring 9, spring 4 compositions such as grade, two sleeves 3 screw by the screw thread of afterbody endoporus separately and screw thread to the silk external diameter respectively and connect, external screw thread 11 (12) to the silk both sides is respectively left hand thread and right-handed thread, with silk is screwed two sleeve 3 internal threads that connect, also be respectively left hand thread and right-handed thread, it is tapered that sleeve configuration becomes, be provided with limited block 10 in the sleeve, be placed with two half cone type fixture blocks 2 in each sleeve, fixture block 2 inboards are provided with pawl 8, to a dividing plate 6 that combines as a whole with inner chamber is arranged in the middle of silk 5 inner chambers, make left, each self-enclosed independence of right sleeve chamber, be provided with spring 4 between fixture block 2 tail ends and the shelves ring 9 in the sleeve chamber, shelves ring 9 is stuck on the limited block 10.
The reinforcing bar connector that has pre-tightening apparatus that the utility model provides, in use, reinforcing bar imports reinforcing bar connector along tooth, the steel bar end of insertion end withstands on the dividing plate 6 in silk 5 inner chambers, because the effect of taper effect, two springs 4 are oppressed two corresponding fixture block tail ends respectively, make the pawl 8 and reinforcing bar 1 obvolvent of two corresponding fixture blocks 2, when screwing, the dividing plate 6 of silk 5 is oppressed reinforcing bars to outer displacement, just be subjected to the effect of 8 interlocks of fixture block upper inverted tooth and taper effect silk 5, make the pawl of two symmetrical fixture blocks shoot reinforcing bar, thereby, make it more firm, can not become flexible.Have the both sides symmetry of the reinforcing bar connector of pre-tightening apparatus, structural principle is identical.The fixture block 2 stressed sleeves 3 of giving, under the situation of sleeve 3 tensile strength greater than reinforcing bar tensile strength, the reinforcing bar connector that has pre-tightening apparatus can be not destroyed.
