Description

A kind of Portable reinforcing steel bar tensile strength detection means
Technical field
The utility model is related to detection device technical field, more particularly to a kind of Portable reinforcing steel bar tensile strength detection dress Put.
Background technology
Reinforced bar engineering is the most important thing in construction, has obtained more and more widely should at present in construction With.In order to strengthen the control to reinforcing bar presentation quality, enter during the entering of reinforcing steel bar and using the preceding presentation quality tackled into factory's reinforcing bar Row checks (exhaustive test).Reinforcing bar should straight, not damaged, surface must not have crackle, greasy dirt, graininess or sheet to become rusty always, bend Reinforcing bar is used after must not striking directly as steel bar stress.Reinforcing bar is most important to the bearing capacity of concrete structure member, to its quality It should require as strict as possible.
The tensile strength of reinforcing bar is a very important technical indicator of reinforcing bar.It is typically by steel to be checked in the prior art The tensile strength detection that laboratory carries out reinforcing bar is taken in muscle sampling to.The drawbacks of this detection means is to be examined at the scene Survey, the sample for taking laboratory to is likely to be the high-quality reinforcing bar prearranged, and may adulterate is applied to after sensing In building, the hidden danger so brought to construction quality.
Utility model content
The purpose of this utility model be to overcome the defect of prior art there is provided one kind it is simple in construction, be easy to carry, can be with The Portable reinforcing steel bar tensile strength detection means detected at the construction field (site) to steel bar stretching intensity.
The technical solution adopted in the utility model is:
A kind of Portable reinforcing steel bar tensile strength detection means, it is characterised in that:Device includes circular base and top plate, Central position is provided with the mounting hole of identical size on the base and top plate, and the mounting hole is into matching somebody with somebody in frustum and mounting hole Then the spring chuck of the taper of conjunction, reinforcing bar two ends to be detected wear spring clip through the mounting hole on base and top plate Cover reinforcing bar two ends to be detected and reinforcing bar is encased in mounting hole together with spring clip set, still set between the base and top plate There is the electric hydraulic lifting jack of 2~4 synchronous workings, be evenly distributed between the base and top plate, each described electronic Connect at the top of piston rod of hydraulic jack between top plate provided with independent a pressure sensor and pressure sensor with controller Connect, prefastened timing, spring clip be enclosed in the mounting hole of frustum shape occur it is relative slide, force spring chuck to draw in and by steel Muscle, which is held tightly, to be fixed, and then proceedes to promote base and top plate to promote both to occur relative slide and by pressure by electric hydraulic lifting jack Sensor record steel bar stretching until fracture when pressure and be converted into tensile strength.
Further, offered respectively at the base upper surface and the corresponding position of top plate lower surface lower locating slot and Upper locating slot, electric hydraulic lifting jack lower end can be plugged into lower locating slot, electric hydraulic lifting jack piston rod part and pressure Sensor can be plugged into locating slot, realize the quick location and installation of electric hydraulic lifting jack between base and top plate.
Further, a lead, the lead lower end and base spiral shell are additionally provided between the base and top plate Line is connected, and top plate is passed through on the vertical direction of upper end, dismounting is easily installed, and play guide effect.
Further, air-bubble level is housed on the base, base keeps horizontality during test, reinforcing bar is only erected Nogata to stretching.
The beneficial effects of the utility model are:
Compared with prior art, the utility model Portable reinforcing steel bar tensile strength detection means, it is simple in construction, be easy to take Band, can carry out tensile strength detection to reinforcing bar at the construction field (site), prevent from adulterating and bring quality to endanger to engineering.This practicality In new, the clamping of reinforcing bar is carried out using the mounting hole of frustum and the spring clip set of cooperation, and spring clip is enclosed on mounting hole cunning The quick fixation that the reinforcing bar locking being through in spring chuck is clamped and realizes reinforcing bar is gradually tightened up when dynamic.Due in bottom plate and top plate Being provided with is used for lower locating slot and upper locating slot that electric hydraulic lifting jack Fast Installation is positioned, and achievable device is quickly assembled into Position and dismounting, adapt to the quick detection requirement of job site.
