Description

Technical field [0001] The invention relates to a civil construction tool, in particular to a detection hammer for civil construction. Background technique [0002] At present, in building construction, after the concrete elements or walls are whitewashed, the wall bulges or forms a cavity due to various factors. The hollow drum is caused by the presence of air in the original masonry and the powder ash layer. When testing, tap the plaster layer and leveling layer with a hollow hammer or a hard object to make a buzzing sound. The "empty drum" in the quality of a house generally refers to the gap between the floor, wall, ceiling decoration layer (plastered or pasted brick) and the structural layer (concrete or brick wall) due to poor bonding and weak bonding. The drum phenomenon is commonly known as "two-layer skin". The hollow drum inspection hammer is a commonly used hollow drum inspection tool, and is an indispensable acceptance tool for quality inspectors and home inspectors...

Problems solved by technology

Small hammer hollowing detection hammers are usually used in China, but the small hammer type detection hammer can only be used for hollowing detection on lower walls and floors, and after a long time of use, the hammer head is easy to fall off the handle during the detection process

In addition, the handle and hammer shaft of the above-mentioned detection hammer are fixed in length and cannot be freely expanded and contracted. For buildings that are too high, the length may not be enough, and a longer handle and hammer shaft need to be remade; for buildings that are too low, it may be due to It is too long to affect the detection, and it is also necessary to remake the shorter handle and hammer shaft
