Embodiment Construction
[0009] In conjunction with the accompanying drawings, the present invention will be described in further detail.
[0010] The invention discloses a knocker for construction engineering, which comprises a pointed head (1), a fixed rod (2), a movable ring (3) and a collar (4).
[0011] When in use, put the collar (4) on the connecting pipe (7) first, align the tip (1) on the template (5) to be fixed, and keep the movable ring (3) centered on the connecting pipe (7) , located on the other side of the template (5), the plane of the collar (4) and the connecting pipe (7) form an angle greater than 90 degrees; hit the collar (4) horizontally with a hammer, and then hit the pointed end with a hammer (1) on the back side, so that the tip (1) and the template (5) are tightly fixed together; hit the end of the fixed rod (2) connected with the movable ring (3) with a hammer, and the tip (1) is continuously embedded template (5), and the movable ring (3) constantly moves towards the lowe...

The invention discloses a knocker for construction engineering, which comprises a pointed head, a fixed rod, a movable ring and a collar. When in use, first put the collar on the connecting pipe so that the tip is aligned with the template to be fixed; hit the collar with a hammer horizontally, and then hit the back of the tip with a hammer to make the tip and the template tightly Fix together; use a hammer to hit the end of the fixed rod connected with the movable ring, the pointed end is continuously embedded in the mold plate, and the movable ring is constantly moving to the lowest point of the collar at the position of the collar, the movable ring is lower than the horizontal angle, and the fixed rod is not It only needs to be in contact with the connecting pipe until it reaches the limit. At this time, the formwork, the connecting pipe and the vertical pipe are firmly fixed together by knocking. At the end of the project, you only need to hit the fixing rod and the collar at the opposite position to disassemble the knocker, so that the knocker can be recycled. The invention has the advantages of simple structure, convenient and fast use, excellent effect, recyclable use, avoiding waste of building materials, and is an indispensable tool for construction engineering.
Description
technical field [0001] The invention relates to a construction engineering appliance, in particular to a construction engineering knocker, which belongs to the technical field of construction engineering. Background technique [0002] In the construction site, it is often necessary to fix the steel pipe fixed in the concrete with the mold above to ensure that the mold will not be deformed when the concrete is poured. The existing technology adopts steel bars, wooden strips and steel nails to fix the mould. Although it can play the role of fixing the mould, it is time-consuming and laborious to install and disassemble. Such devices are disposable and have the disadvantage of wasting building materials. Contents of the invention [0003] In order to solve the above-mentioned problems in the prior art, the present invention discloses a knocker for construction engineering, which includes a pointed head, a fixed rod, a movable ring and a collar. When in use, put the collar on...
