Abstract
The utility model relates to the field of engineering detection, in particular to a fixture for quickly unloading a planted rib drawing detection method; the method is characterized in that: the clamping piece is arranged in the anchor fixing part, bolt holes are formed in the side part of the anchor fixing part, and the jacking bolt penetrates into the bolt holes; therefore, when the jacking bolt is screwed down, the clamping piece and the anchorage device fixing part are closed and clamped, and when the jacking bolt is unscrewed, the clamping piece is loosened and can be easily taken down. The scheme redesigns the anchorage device, changes the anchorage device into a partially fixed and partially movable mode, and forms a whole by the anchorage device fixing part, the sliding groove and the screw hole. The driving screw controls the movable part of the anchorage device to move in the chute.
Description
Technical Field
The utility model relates to the field of engineering detection, in particular to a clamp for quickly unloading a planted rib drawing detection method.
Background
Along with the transformation of national policies, the building construction mode of large-dismantling and large-building is adjusted into the building repair and reconstruction and the PC assembly type building, the post-reinforcement anchoring technology is widely applied to the structural reinforcement and the assembly type building masonry structure, the chemical method reinforcement is the chemical method reinforcement planting glue planting reinforcement of the building engineering, called as the planting reinforcement for short, also called as the planting reinforcement, is a reinforcement post-anchoring technology on the existing earthquake-resistant reinforcement engineering of the building structure, and is a good choice for the application of the reinforcement of the structure planting reinforcement and the fastening of heavy load. The drawing test is a common test for detecting whether the post-anchoring technology of the steel bar is qualified or not.
At present, a clamp used for a bar planting drawing test is generally formed by two parts, wherein one part is a clamping piece, the inside is cylindrical and is carved with parallel grains, and the outside is conical. The other part is an anchorage device, the outer part is a cylinder, and the inner part is a cone. When the drawing test is carried out, the jack jacks up the anchor to provide upward pulling force, then the anchor restrains the clamping piece from the side surface through the wedge effect, the embedded steel bar is clamped, and the pulling force is transmitted to the embedded steel bar. However, after the loading is finished, the clamping pieces are tightly engaged with the anchorage device due to overlarge stress, so that the unloading is difficult, the anchorage device is usually knocked by a large impact load to be separated, the anchorage device is easily damaged, and the working efficiency is seriously influenced.
Disclosure of Invention
The utility model aims to overcome the defects and provides a quick unloading clamp for a bar planting drawing detection method, which is easy to use and has a good effect.
In order to achieve the above object, the present invention is realized by:
a clamp for quickly unloading a planted rib drawing detection method comprises an anchor fixing part, clamping pieces and a puller bolt, wherein the anchor fixing part is hollow, the bottom of the anchor fixing part is provided with a hole, the clamping pieces are arranged inside the anchor fixing part, the side part of the anchor fixing part is provided with a bolt hole, and the puller bolt penetrates through the bolt hole; therefore, when the jacking bolt is screwed down, the clamping piece and the anchorage device fixing part are closed and clamped, and when the jacking bolt is unscrewed, the clamping piece is loosened and can be easily taken down.
The clamp is quickly unloaded by the bar planting drawing detection method, and the contact surface between the anchor fixing part and the clamping piece is a conical surface.
The scheme redesigns the anchorage device, changes the anchorage device into a partially fixed and partially movable mode, and forms a whole by the anchorage device fixing part, the sliding groove and the screw hole. The driving screw controls the movable part of the anchorage device to move in the chute.
Drawings
Fig. 1 is a schematic structural view of the present clamp.
Detailed Description
The utility model is further illustrated by the following specific examples.
As shown in fig. 1, a rapid unloading clamp for a planted bar drawing detection method comprises an anchor fixing part 1, a clamping piece 2 and a puller bolt 3, wherein the anchor fixing part 1 is hollow and is provided with a hole at the bottom, the clamping piece 2 is arranged inside the anchor fixing part 1, a bolt hole is formed in the side part of the anchor fixing part 1, and the puller bolt 3 is inserted into the bolt hole; so, when tightening bolt 3 was screwed up, clamping piece 2 and ground tackle fixed part 1 closed and press from both sides tightly, and when tightening bolt 3 was unscrewed, the clamping piece was not hard up, can easily take off.
The clamp is quickly unloaded by the bar planting drawing detection method, and the contact surface between the anchor fixing part 1 and the clamping piece 2 is a conical surface.
The scheme redesigns the anchorage device, changes the anchorage device into a partially fixed and partially movable mode, and forms a whole by the anchorage device fixing part, the sliding groove and the screw hole. The driving screw controls the movable part of the anchorage device to move in the chute.
Claims (2)
1. The utility model provides a planting muscle is drawn and is detected quick uninstallation anchor clamps of method, characterized by: the clamping piece is arranged inside the anchorage device fixing part, a bolt hole is formed in the side part of the anchorage device fixing part, and the jacking bolt penetrates into the bolt hole.
2. The clamp for rapidly unloading the implanted steel bar drawing detection method according to claim 1, which is characterized in that: the contact surface between the anchor fixing part and the clamping piece is a conical surface.
