Description

Novel steel bar stress meter

Technical Field

The utility model belongs to foundation ditch engineering monitoring field especially designs a novel reinforcing bar stressometer.

Background

In some foundation pit projects, an inner support needs to be arranged. At present, reinforced concrete is commonly cast in situ or section steel is commonly used as an inner support. Generally, axial force monitoring of these internal supports is required. If the alarm value is exceeded, an alarm is given in time to inform the first party, design, construction and supervision to carry out on-site shutdown and emergency rescue.

For the support of the section steel, a surface stress meter can be welded on the surface of the section steel; for example, chinese patent publication No. CN208333716U discloses a novel steel bar stress gauge for a steel pipe pile, which includes a connecting rod brazed with the steel pipe pile, the connecting rod is provided with the stress gauge, the connecting rod is provided with two asbestos insulation layers, the two asbestos insulation layers are respectively located at two sides of the stress gauge, two ends of the connecting rod are both provided with welding scales, and the distance from the two ends of the connecting rod to the nearest welding scales is the same.

For the reinforced concrete inner support, two vibrating wire type reinforcing steel bar stressometers are bound in a reinforcing cage before concrete is poured in situ. A conventional bar stress gauge requires a bar of steel to be mounted at each end. So that the stress meter brings certain difficulties in the transportation and field handling processes.

The traditional installation method is that a steel bar and a stress gauge are connected, and then the steel bar stress gauge is bound in a steel bar cage by adopting a binding wire. This installation method requires a field technician to tie the tie wire, or else, a field rebar worker is required to assist in the field tie. In real-world projects, however, the rebar workers often do not assist field installers. Meanwhile, as the steel bar is heavier, more stress timers are installed on site at one time, and fatigue is easy to generate.

In addition, foundation pit engineering is to excavate the earthwork at night. Night vision can become more blurred relative to day time, and excavators tend to stand on the inner support beams for excavation. These factors increase the risk of the rebar stressor cable being damaged.

SUMMERY OF THE UTILITY MODEL

In view of the above problem, the utility model provides a novel steel bar stress meter has the advantage of being convenient for transport, on-the-spot simple to operate and indestructible.

The technical scheme of the utility model as follows:

the utility model provides a novel reinforcing bar stressometer for install in the interior support steel reinforcement cage of foundation ditch engineering, including the stressometer body and fixed at least one buckle structure who sets up on the stressometer body, the cable outside on the stressometer body is equipped with the protective sheath, and the terminal portion setting of cable is in the cable protection box.

The utility model discloses a stressometer, simple structure, simple to operate puts the cable in the protection box simultaneously, can reduce the risk of being destroyed by the machine of digging during the excavation.

Preferably, the number of the buckle structures is two, and the two buckle structures are respectively arranged at two ends of the stress meter body.

Preferably, the buckle structure include with the fixed draw-in groove of stressometer body and with draw-in groove one end articulated buckle, the free end of buckle pass through the bolt with the other end of draw-in groove and can dismantle fixedly. When the novel clamping groove is used specifically, the clamping groove is hinged to one end of the clamping buckle, and the bolt can be matched to conveniently install and disassemble.

Further, the inner groove face of the clamping groove is fixed with the stress meter body, and in the installation state, the clamping structure fixes the reinforcing steel bar in the reinforcing cage together with the stress meter body.

Preferably, a light-emitting body is arranged on a box cover of the cable protection box, and a battery connected with the light-emitting body is arranged in the cable protection box. After the luminous body is arranged on the box cover, the box cover has a luminous function, so that the risk of damage of an excavator during excavation can be reduced when the foundation pit engineering excavates the earth at night.

Furthermore, the luminous bodies are a plurality of lamp belts which are uniformly arranged on the box cover, so that the cable protection box is more striking at night.

Compared with the prior art, the utility model discloses following beneficial effect has:

the utility model discloses a set up buckle structure on the stressometer body, convenient and the fixed of reinforcing bar, put the cable in the protection box simultaneously to set up the luminous body on the lid of protection box, can reduce the risk of being destroyed by the excavator during the excavation.
