Abstract

One sleeve hoops the two tiles to tightly clamp the steel bar joint; the shape is as follows: the steel bar splicing sleeve comprises a sleeve, two tiles and two spliced steel bars; the technical points of the structure are as follows: a sleeve is used for hooping two tiles, and the end parts of two jointed steel bars are tightly clamped between the two tiles.

Description

One sleeve hoops two tile tightly-clamped steel bar joints

Technical Field

The application relates to the building industry and the field of steel bar joints thereof.

Background

The steel bar joint in the building industry generally adopts lap welding, a screw thread joint or a mechanical cold extrusion sleeve at present, electroslag pressure welding is suitable for a vertical steel bar joint, and the joint method is not simple and convenient enough in construction; is simple and convenient.

Disclosure of Invention

The utility model discloses a, the technical problem that solve is: overcome above-mentioned drawback, adopt a sleeve, hoop two tiles, tightly press from both sides the technical paper of two quilt joint reinforcing bars. The product shape is as follows: the sleeve (1) has the inner wall taper consistent with the taper of the tiles (the outer wall after being attached to the steel bars), hoops the two tiles (2) and clamps the end parts of the two jointed steel bars (3). The plane of one end part of each of the two tiles is reserved with a prying and turning anchor (4), a starter is inserted into a clamping groove suitable for a gap at the end part of the tile, and the groove is replaced for multiple times to pry, turn and hammer for anchoring so as to prevent the vibration concrete sleeve from sliding; the outer walls of the two tiles are provided with barb nicks (5); the inner walls of the two tiles are provided with barb nicks (6); the inner walls of the two tiles are provided with reinforcing steel bar concave groove lines (7); the two tiles are internally provided with isolation belts (8); the sleeve is internally provided with a barb nicking (9); the end part of the big hole on the inner wall of the sleeve is chamfered (10). The beneficial effects are as follows: compared with the prior electroslag pressure welding which can only be used for vertical steel bar joints, the operation process is complex, and the quality is not stable enough; the connector has the advantages that not only can the vertical steel bars of the pillar be used, but also the transverse steel bar connector of the beam plate can be widely applied; compared with the existing mechanical equipment for applying the cold extrusion sleeve, the equipment is simpler; compared with the existing screw thread turning, the method is quicker and more convenient; the pulling force of two steel bars to be jointed is attached to the two tiles; the two tiles are locked by the sleeve hoop, namely, the two tiles are broken by the joint steel bar test in a destructive way, and the joint is intact; because the taper is proper, the inner hole of the sleeve is matched with the barbs on the outer walls of the two tiles and is tightened with the barbs; the sleeve is anchored by the plane of the end parts of the two tiles through prying, turning and hammering, and the possibility of retraction is avoided; but also has barb sculptures without slipping; the sectional areas of the two tiles and the sleeve are larger than that of the jointed steel bar, and no fracture occurs.

Drawings

FIG. 1: the steel bar joint is longitudinally and transversely cut to show a sleeve, two tiles and two jointed steel bars; FIG. 2: the two tiles are viewed from the top, sectioned at the vertical surface and flat, and barbs are arranged inside and outside the two tiles; FIG. 3: the sleeve is upward-looking, the vertical surface is cut off, and the plane is a plane, and the inner wall of the sleeve is provided with barbs. In the figure: (1) a sleeve; (2) two tiles; (3) two jointed steel bars; (4) prying, turning and anchoring; (5) the barbs on the outer walls of the two tiles are carved; (6) the inner walls of the two tiles are barbed and grooved; (7) grooving the reinforcing steel bars on the inner walls of the two tiles; (8) two inner isolated zones of tiles; (9) the inner wall of the sleeve is barbed and engraved; (10) the end part of the large hole on the inner wall of the sleeve is chamfered.

Detailed Description

Two tiles (2) are attached to two sides of a jointed reinforcing steel bar (3), an isolation belt (8) is arranged between the two jointed reinforcing steel bars (3), female screw grooves (7) in the inner walls of the two tiles are matched with the screw threads of the jointed reinforcing steel bar (3), one end of a large hole of a sleeve (1) is provided with a chamfer angle and downwards sleeves the two tiles (2), the sleeve (1) is struck to be tight by a hammer, a screwdriver is inserted into a clamping groove suitable for a gap of the end part of the tile, and the tile is repeatedly replaced, turned over and anchored (4) by the hammer; and (5) completing the joint.

Claims

1. A sleeve hoops two tiles and tightly clamps steel bar joint, and its shape, structure include: one sleeve (1), two tiles (2), hoop two and are connected reinforcing bar (3) tip, its characterized in that: the plane of the end part of one end of each of the two tiles is reserved with a prying and turning anchor (4) to prevent the vibration concrete sleeve from sliding; the outer arc walls of the two tiles are provided with two tile outer wall barb nicks (5); the inner arc walls of the two tiles are provided with two tile inner wall barb nicks (6); the inner walls of the two tiles are provided with two tile inner wall steel bar female groove lines (7); two tiles are internally provided with isolation belts (8).

2. The sleeve hooping two-tile clamp rebar junction according to claim 1, wherein: the internal taper of the sleeve is consistent with the shapes of the two tiles, the sleeve is internally provided with a sleeve inner wall barb nicking (9), and the end part of a large hole of the sleeve inner wall is chamfered.
