Description
Technical field
The present invention relates to a kind of quantitative hammer for Site Detection roof color steel plate security.
Background technology
After roof color steel plate service life is longer, or the factor due to factory building technique, such as high temperature, high humidity, acid mist influence, and roof color steel plate corrosion, rotten situation can occur, some is also very serious, rotten may wear.The industrial premises of metallurgical class is often provided with dormer for the needs of technique productions in roofing, and its internal roof boarding is more easy to rotten rotten, and is not easy to be noticeable, serious potential safety hazard is brought to the operating personnel for entering deashing inside dormer.
Currently used detection means is to use calibrator to detect color steel thickness to judge its security, but because the thickness of color steel is relatively partially thin, the reaction of calibrator is insensitive, and the problem of bigger is for corrosion and the rotten color steel worn, the usual None- identified of thickness gauge, therefore under these conditions, color steel can not implement effective thickness measuring.
Another detection means is directly measured using slide measure, because live color steel is large area tiling, people is located above color steel, therefore only color steel edge ability measure thickness, middle part can not measure, therefore measurement data is not used to the judge of color steel security.
How the security of roof color steel plate people from station is judged, by the color steel of corrosion whether also in safe range, never proper method is used for field test, but is a urgent problem to be solved.When color steel bending resistance deficiency, it may appear that the deformation of larger roofing downwarp formula, is typically not in momentary breakdown phenomenon, the people walked on roofing has dangerous premonition；But when the shear resistance deficiency of color steel, meeting momentary breakdown, the people walked on roofing understands moment and fallen.
The content of the invention
The technical problems to be solved by the invention are to provide a kind of quantitative hammer for Site Detection roof color steel plate security, the defects of this quantitative hammer overcomes traditional roof color steel Thickness sensitivity mode, can effective detection roof color steel plate security performance, avoid color steel corrosion or rotten caused potential safety hazard, and it is simple in construction, it is easy to operate.
To solve above-mentioned technical problem, the quantitative hammer that the present invention is used for Site Detection roof color steel plate security includes sleeve pipe, connecting screw and some circular steel plates, some circular steel plate arranged stackeds and center is provided with through hole, the connecting screw penetrates the central through hole of some circular steel plates and both ends are fastened using packing ring and nut, the connecting screw is located at described sleeve pipe top together with some circular steel plates, and the diameter of some circular steel plates is less than the internal diameter of described sleeve pipe.
Further, the connecting screw bottom is spherical.
Further, described sleeve pipe surface is provided with altitude scale line.
Further, a diameter of 81mm of the circular steel plate, thickness 25mm, weight 1Kg.
The quantitative hammer for being used for Site Detection roof color steel plate security due to the present invention employs above-mentioned technical proposal, i.e. this quantitative hammer includes sleeve pipe, connecting screw and some circular steel plates, some circular steel plate arranged stackeds and center is provided with through hole, connecting screw penetrates the central through hole of some circular steel plates and both ends are fastened using packing ring and nut, connecting screw is located at cannula tip together with some circular steel plates, and the diameter of some circular steel plates is less than the internal diameter of sleeve pipe.The defects of this quantitative hammer overcomes traditional roof color steel Thickness sensitivity mode, can effective detection roof color steel plate security performance, avoid color steel corrosion or potential safety hazard caused by rotting, and simple in construction, it is easy to operate.
Brief description of the drawings
The present invention is described in further detail with embodiment below in conjunction with the accompanying drawings：
Fig. 1 is the quantitative hammer structural representation that the present invention is used for Site Detection roof color steel plate security.
Embodiment
Embodiment is as shown in Figure 1, the quantitative hammer that the present invention is used for Site Detection roof color steel plate security includes sleeve pipe 1, connecting screw 2 and some circular steel plates 3, the arranged stacked of some circular steel plates 3 and center is provided with through hole, the connecting screw 2 penetrates the central through hole of some circular steel plates 3 and both ends are fastened using packing ring and nut, the connecting screw 2 is located at the top of described sleeve pipe 1 together with some circular steel plates 3, and the diameter of some circular steel plates 3 is less than the internal diameter of described sleeve pipe 1.
Preferably, the bottom of connecting screw 2 is spherical.Reliable impact of the connecting screw bottom to color steel when dropping hammer that spherical ensure that, avoids sharp termination from being damaged to caused by color steel, improves the reliability of detection.
Preferably, the surface of described sleeve pipe 1 is provided with altitude scale line 11.Altitude scale line is conveniently adjusted height of the fall so that detection is more accurate.
Preferably, a diameter of 81mm of the circular steel plate 3, thickness 25mm, weight 1Kg.Circular steel plate is easy to make, the foundation that nominal weight can calculate as drop impact power.
Reached the phenomenon that can be destroyed after certain value by punching based on color steel, be equal to the state of color steel shear resistance deficiency of the people when being walked on roofing, you can the security after the corrosion of Site Detection color steel.As shown in Figure 1,When quantitatively hammering examinations into shape using this,The shear resistant capacity of roof color steel plate 4 is derived according to the deployment scenarios of the thickness of color steel 4 and roof purline synthesis first,3 numbers of circular steel plate and height of the fall that this is quantitatively hammered into shape according to shear resistant capacity adjustment,Then sleeve pipe 1 is placed in the measuring point of color steel 4,Connecting screw 2 and circular steel plate 3 are located at the top of sleeve pipe 1 and adjust height of the fall,Circular steel plate 3 drives connecting screw 2 in the interior motion of dropping hammer of sleeve pipe 1 after unclamping connecting screw 2,Sleeve pipe 1 plays a part of guiding,The now bottom of connecting screw 2 impact roof color steel plate 4,I.e. when the impulsive force of certain value impacts roof color steel plate 4,Such as fail to puncture color steel 4,Illustrate that the color steel 4 at the measuring point has certain shear resistance,Its residual thickness is not less than the force value of the punching,And the force value of the punching may be set to the minimum value of the safety of roof color steel plate 4；Such as the bottom of connecting screw 2 breakdown color steel 4, then illustrate that the residual thickness of the color steel 4 is less than safety value, potential safety hazard be present.After quantitatively being hammered into shape by this to roof color steel plate multiple spot examinations, the security performance of roof color steel plate can be reviewed comprehensively, it is ensured that the safety of roofing operating personnel.
This quantitative hammer can realize that multipoint random detects for roof color steel plate at the scene, according to the requirement of roof color steel plate least residue thickness, by change circular steel plate number can the impulsive force dropped hammer of quantitative adjusting, it is and simple in construction, it is easy to carry, facilitates the implementation of detection operation.
