Abstract
Disclosed is a captive clamping plate, and guide traction wire ropes used for the existing buildings are connected with anchors through hoisting rings, which easily results in separation between lifting rings and nut plates. The captive clamping plate is composed of a round clamping plate (1), and a U-shaped clamping notch (2) and two bolt holes (3) are arranged on the round clamping plate. The captive clamping plate is used as a constituent fitting for the guide traction hoisting rings.
Description
Technical field:
The utility model relates to a kind of anti-drop device of architectural use, is specifically related to a kind of slip-off preventing clamp.
Background technology:
The guiding haulage cable of present architectural use is connected with the anchor cup by suspension ring, and its connecting device has two parts, and one is the inner nut plate, and it two is a terminal filament button, and the other end is the suspension ring of annulus.Its inner nut plate thickness is 3 centimetres, diameter and anchor cup interior diameter are adopted screw thread precession anchor cup inwall unanimously, and there is the keyhole of 3 cm diameters at inner nut plate center, is used to install suspension ring, behind inner nut plate precession anchor cup,, finish being connected of steel rope and anchor cup with suspension ring precession inner nut plate.Because inner nut plate centre hole screw thread and suspension ring screw thread are the fine limit work screw thread, its friction drag is very little, promptly can rotate by very little twisting resistance, comes off easily, and is little if execute-in-place is screwed into screw thread, easier suspension ring and the nutplate problem that comes off that occurs.
Summary of the invention:
The purpose of this utility model provides a kind of slip-off preventing clamp, and is simple in structure, easy to install.
Above-mentioned purpose realizes by following technical scheme:
The slip-off preventing clamp, its composition comprises: circular clamp has U-shaped draw-in groove and two bolts hole on the described circular clamp.
The beneficial effects of the utility model:
The U-shaped draw-in groove of this product is used in the rope traction device, can prevent suspension ring rotations and the nutplate problem that comes off, it is installed in the anchor rim of a cup, nutplate can not protrude in the anchor rim of a cup like this, suspension ring also are stuck and rotation phenomenon can occur, prevent the damage of the anchor cup screw thread that coming off of the process of lifting by crane caused.
Description of drawings:
Accompanying drawing 1 is the structural representation of this product.
The specific embodiment:
Embodiment 1:
The slip-off preventing clamp, its composition comprises: circular clamp 1 has U-shaped draw-in groove 2 and two bolts hole 3 on the described circular clamp.
Described circular clamp external diameter is consistent with the anchor cup, the effect of bolt hole is circular clamp to be connected (the flat mouth of anchor cup leaves interior screw thread) with anchor cup outer wall, during concrete the installation, suspension ring be connected with the inner nut plate finish after, circular clamp is installed in the anchor rim of a cup, nutplate can not protrude in the anchor rim of a cup like this, suspension ring also are stuck and rotation phenomenon can occur, prevent anchor cup and king-post collision that coming off of the process of lifting by crane caused, damage anchor cup screw thread, influence the installation of sealing off and covering anchorage screw, avoided extension rope potential safety hazard.
Claims (1)
1. slip-off preventing clamp, its composition comprises: circular clamp is characterized in that: have U-shaped draw-in groove and two bolts hole on the described circular clamp.
