Problems solved by technology

The two patents are threaded connections, which need to be threaded in the end of the steel bar and the anchor plate. The threads need to be processed in the factory. The tightening torque value needs to be controlled when the anchor plate is installed on site, and the construction quality is difficult to control.
Welding method such as figure 2 As shown, perforated plug welding is generally used, and the construction quality is limited by the welder's level, on-site construction conditions, weather, temperature and other conditions, and once the construction quality is unqualified, the rework workload will be large

Embodiment

[0038] Such as Figure 4 As shown, insert the steel bar 5 into the self-contained sleeve 2 on the end anchor plate, the end of the steel bar goes deep into the bottom of the sleeve, and turn the anchor plate sleeve 2 properly so that the rib side of the steel bar 5 is aligned with the sleeve 2. threaded hole 3; several pointed screws 4 are screwed into the threaded hole 3 and tightened successively; tighten the pointed screw 4 with an electric wrench until the nut on the screw is broken to form an anchoring device for the tensile steel bar 5, such as Figure 5 shown.

[0039] The specifications of the anchoring device components in this embodiment are as follows:

[0040] Anchor plate: thickness 32mm, diameter 96mm.

[0041] Sleeve: wall thickness 6mm, outer diameter 54mm, inner diameter 42mm, length 160mm, the surface of the inner wall is sandblasted or scored.

[0042] Threaded holes: Select 5 threaded holes with an inner diameter of 8mm and arrange them at equal interval...

Abstract

The invention discloses a reinforcement anchorage, comprising an anchor plate, screws and rebars. The anchor plate comprises a sleeve which is provided with holes; the rebars are inserted into the sleeve; the screws are mounted in the holes of the sleeve to fix the rebars. By using the reinforcement anchorage, anchoring length of the rebars is decreased, mounting the anchor plate is convenient and simple, and controlling is easy.

Description

technical field [0001] The invention relates to a steel bar anchoring device and an installation method, belonging to the field of civil engineering. Background technique [0002] The steel bar anchorage plate is a component composed of the anchor plate and the steel bar. It is a new type of steel bar anchorage. It uses the bond strength between the steel bar and the concrete and the pressure bearing capacity of the anchor plate to jointly bear the tensile force on the steel bar, so that the tensile strength of the steel bar get the most out of it. This kind of reinforcement anchorage method can effectively avoid the defects caused by the traditional reinforcement straight anchor or curved anchor in the design and construction, such as the congestion of reinforcement in the node area, the collision of the main reinforcement and the bending reinforcement, and the size of the component cannot meet the anchorage length. The steel bar anchorage plate reduces the anchorage lengt...
