AI Technical Summary
In the process of chiseling the old and new concrete junction surfaces of the shear wall, existing tools are inefficient and laborious due to the influence of steel bars, making it difficult to effectively chisel.
A concrete surface wool puller at the joint of the shear wall is designed, including a box, baffle, U-shaped hole, through hole and wool pull hook. The wool pull hook is connected by a spring, and the spring can be compressed to avoid resistance to steel bars and realize the hook-like structure. It automatically retreats, and other hooks can freely enter the wall for hair removal.
The burr ratio and working efficiency are improved, especially when the wall width is greater than 200mm, it can alternately burr on both sides to achieve a burr ratio of more than 90%.

Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of construction equipment, in particular to a concrete surface roughening device at a shear wall joint. Background Art
[0002] Since the conventional reinforcement of concrete shear wall is double-layer and bidirectional and the steel bar specifications are mostly below 18mm, the roughening area processed by ordinary workers using single-head roughening tools in one cycle is very limited, and the high-efficiency roughening tools cannot enter the wall due to the influence of steel bars. This makes it troublesome, laborious, inefficient and low-roughening work for workers to engage in the roughening of the interface between the new and old concrete of the shear wall. Summary of the invention
[0003] In view of this, the purpose of the utility model is to provide a concrete surface roughening device at the joint of a shear wall to solve the problems mentioned in the above background technology.
[0004] In order to achieve the above purpose, the technical solutions adopted are as follows:
[0005] The concrete surface roughening device at the joint of the shear wall comprises a box body, a baffle is vertically inserted inside the box body, the baffle is parallel to the side plates at both ends of the box body, a plurality of U-shaped holes are evenly spaced on the baffle, a row of through holes are evenly spaced on the side plate at one end of the box body, the through holes correspond to the U-shaped holes one by one, roughening hooks are penetrated on the through holes and the U-shaped holes, one end of the roughening hook outside the box body is hook-shaped, the whole is a rod-shaped structure, and the other end of the roughening hook passes through the U-shaped hole;
[0006] The roughening hook is provided with a spring between the baffle plate and the side plate of the box body with a through hole, one end of the spring is connected to the baffle plate, and the other end of the spring is connected to the roughening hook.
[0007] As a further improvement of the utility model, one end of the spring away from the baffle is connected to the rectangular clamping pad, and the rectangular clamping pad is fixedly installed on the napping hook.
[0008] As a further improvement of the utility model, a handle is fixedly mounted on the outer wall of the side plate at one end of the box body away from the napping hook, and a box cover is mounted on the upper part of the box body, and the box cover is hingedly mounted on the box body.
[0009] As a further improvement of the utility model, the spacing between the napping hooks is ≤30 mm, and the lower end of the rectangular card pad is attached to the bottom of the box body.
[0010] The beneficial effects of the utility model are:
[0011] The device has a simple structure. When the device is used for roughening, there is no need to deliberately avoid the steel bars. The roughening hooks that encounter the steel bars are compressed by the resistance of the steel bars and retreat into the box body without participating in the roughening work. The other roughening hooks that are not affected by the steel bars enter the shear wall to perform the roughening work. When the wall width is greater than 200mm, the roughening can be performed alternately on both sides of the wall to achieve the roughening rate and work efficiency, and the roughening rate is above 90%. BRIEF DESCRIPTION OF THE DRAWINGS
[0012] The drawings constituting a part of this application are used to provide a further understanding of the present invention. The illustrative embodiments of the present invention and their descriptions are used to explain the present invention and do not constitute an improper limitation on the present invention. In the drawings:
