Abstract
The utility model relates to a concrete thickness detection ruler. It is difficult to control the thickness of concrete floors in a building engineering construction process, so in order to solve the above technical scheme, the detection ruler comprises a handle and main ruler; the whole detection ruler is T-typed; scales are arranged on the main ruler; and a zero scale is arranged on the lower end part of the main ruler. The detection ruler is characterized in that the main ruler is in the shape of a cylinder; a vernier is arranged on the main ruler; the vernier is in the shape of an inverted frustum; a central hole is arranged in the vernier; a threaded through hole inclining upwards is arranged in the side wall of the vernier; the threaded through hole is communicated with the central hole; the diameter of the central hole is slightly larger than that of main ruler; a braking screw is arranged on the vernier; and the braking screw passes through the threaded through hole and presses the main ruler in an upwards-inclining manner. The detection ruler is simple and easy to operate, measuring errors are small and the detection ruler can be widely applied to various building construction measuring work.
Description
Technical field
The utility model relates to a kind of survey instrument, particularly a kind of concrete thickness detection ruler.
Background technology
Concrete is one of contemporary topmost civil engineering material, and it is by consolidating material, and gather materials (also referred to as aggregate) and water are prepared by a certain percentage, through stirring the moulding of vibrating, the artificial stone that maintenance under certain condition forms.In the time of structure of reinforced concrete, unit in charge of construction normally makes a kind of reinforcing bar inserted link by oneself, and with the bar reinforcement brachymemma steel bar end of burn-oning in bottom, bar dowel head equates with the thickness of institute casting concrete apart from the distance of bottom, plays a kind of spacing effect.The unit in charge of construction also having checks and controls the concrete thickness of building with level meter and Sopwith staff.In use all there is certain shortcoming in these two kinds of instruments, reinforcing bar inserted link generally can only be for detection of a kind of thickness, and level meter and Sopwith staff need two people to operate, and operation steps is more loaded down with trivial details.
Utility model content
The utility model will solve thickness of concrete floor technical matters rambunctious in Building Construction, and a kind of concrete thickness detection ruler is provided.
For solving the problems of the technologies described above, this concrete thickness detection ruler comprises handle and main scale, it is T-shaped that entirety is, on main scale, there is scale, 0 scale is located at the bottom of main scale, it is characterized in that: described main scale is cylindrical, which is provided with vernier, vernier is inversed taper platform shape, and has center pit, has tapped through hole obliquely on vernier lateral wall, tapped through hole communicates with center pit, the slightly larger in diameter of center pit, in the diameter of main scale, is also provided with clamping screw on vernier, clamping screw is against on main scale obliquely through tapped through hole.
Design like this, vernier is by clamping screw control, and while inserting main scale, loosening clamping screw, moves on vernier is convenient, and main scale is tightened clamping screw after stopping moving, and vernier is fixed, accuracy of reading.
As optimization, the bottom of described main scale is inversed taper platform shape.So design, while inserting concrete, resistance is little, easy to use, laborsaving.
This concrete thickness detection ruler utilizes 8Cr16 steel higher hardness, certain feature such as corrosion stability and good process performance as detecting main scale, on main scale, there is scale, take millimeter as unit, main scale is shaped as T-shaped, T-shaped horizontal segment is shorter, as handle, facilitate personnel to operate, add the vernier design of a same material that can move up and down on main scale, can, according to different slab thicknesses, adjust the position of vernier, after fixing, the floor of building in concrete process is carried out to thickness detection, and vernier thickness is 13mm.
The utility model concrete thickness detection ruler can accurately detect the requirement whether thickness of concrete floor meets concrete construction quality acceptance specification, and simple to operation, avoided slab thickness do not reach design and acceptance specification require the potential safety hazard and the economic loss that cause, be widely used in various building construction measurement operations.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, this concrete thickness detection ruler is described further:
Fig. 1 is the structural representation of this concrete thickness detection ruler;
Fig. 2 is the cursor structure enlarged diagram of this concrete thickness detection ruler;
Fig. 3 is the main scale bottom structure enlarged diagram of this concrete thickness detection ruler.
In figure: 1 is that handle, 2 is that main scale, 3 is that bottom, 4 is that vernier, 5 is clamping screw.
Embodiment
Embodiment one: as Figure 1-3, this concrete thickness detection ruler comprises handle 1 and main scale 2, it is T-shaped that entirety is, on main scale 2, there is scale, 0 scale is located at the bottom 3 of main scale, main scale is cylindrical, which is provided with vernier 4, vernier 4 is inversed taper platform shape, and have a center pit, on vernier 4 lateral walls, have tapped through hole obliquely, tapped through hole communicates with center pit, the slightly larger in diameter of center pit is in the diameter of main scale, on vernier 4, be also provided with clamping screw 5, clamping screw 5 is against on main scale 2 obliquely through tapped through hole, the bottom 3 of described main scale 2 is inversed taper platform shape.
Claims (2)
1. a concrete thickness detection ruler, comprises handle and main scale, and it is T-shaped that entirety is, on main scale, have scale, 0 scale is located at the bottom of main scale, it is characterized in that: described main scale is cylindrical, which is provided with vernier, vernier is inversed taper platform shape, and has center pit, has tapped through hole obliquely on vernier lateral wall, tapped through hole communicates with center pit, the slightly larger in diameter of center pit, in the diameter of main scale, is also provided with clamping screw on vernier, clamping screw is against on main scale obliquely through tapped through hole.
2. concrete thickness detection ruler as claimed in claim 1, is characterized in that: the bottom of described main scale is inversed taper platform shape.
