Abstract
The utility model discloses a kind of shaped steel stress meter, shaped steel internal force is difficult to solve the problems, such as in geotechnical engineering monitoring designs.The utility model is made of fixing device, attachment device, stress meter, wire guide；The fixing device is to be welded with the other steel of building materials ad eundem, outer end with shaped steel to be measured, and inner end is connected with attachment device, and outer end configuration is rectangle, and inner end shape is circle, to transmit the internal force come from shaped steel, and is directed on stress meter；The attachment device is connecting stress meter and fixing device；The stress is calculated as vibratory stress gauge, the stress intensity collected by the vibration frequency identified sign for measuring string wire；The wire guide is the outlet of stress meter data circuit, and stress meter circuit is connect by arriving line traffic control with external stress collecting device.The utility model is simple in structure, be easily installed, engineering practicability is strong, and can effectively solve the problems, such as that shaped steel Internal Force Monitoring is difficult.
Description
Technical field
The utility model belongs to geotechnical engineering technical field of measurement and test, and in particular to a kind of shaped steel stress meter more particularly to one
The kind shaped steel stress meter coaxial with shaped steel stress to be measured.
Background technology
The end of the eighties in last century, China start to introduce SMW engineering methods.But the adhesion strength between soil cement and shaped steel at present
Research it is also insufficient, it is considered that the bonding between soil cement and shaped steel is a kind of flexible adhesion, and adhesion strength cannot be with
Rigid bond between concrete and rebar is compared.This is not meant to imply that cement mixing method does not work to shaped steel, experiment
Research shows that soil cement can improve the package action of shaped steel the rigidity of shaped steel, shaped steel unstability is prevented.Therefore, it is necessary to carry out type
Steel and the research of the soil cement mechanism of action.At present, shaped steel internal force is monitored in experiment usually using Reinforcement Stress-count, but reinforcement stresses
Meter is usually cylinder, and a protrusion can be caused when being welded on shaped steel surface, is easily destroyed in construction；And Reinforcement Stress-count
Main shaft not with shaped steel stress overlapping of axles, monitoring result is inaccurate.Therefore, it is necessary to a kind of shaped steel stress meter of utility model,
To meet the needs of monitoring shaped steel internal force.
Invention content
The purpose of this utility model is to provide a kind of shaped steel stress meter, which not only can effectively solve shaped steel internal force
The problem of monitoring is difficult, and it is simple in structure, be easily installed, Technological Economy it is feasible.
Technical solution adopted in the utility model is：A kind of shaped steel stress meter, it is by fixing device (1), attachment device
(2), stress meter (3), wire guide (4) composition；The fixing device (1) be with the other steel of building materials ad eundem, outer end is with treating
Shaped steel welding is surveyed, inner end is connected with attachment device (2), and outer end configuration is rectangle, and inner end shape is circle, to transmit from type
Steel and the internal force come, and are directed on stress meter (3)；The attachment device (2) is connecting stress meter (3) and fixing device
(1)；The stress meter (3) be vibratory stress gauge, the stress collected by the vibration frequency identified sign for measuring string wire
Size；The wire guide (4) is the outlet of stress meter data circuit, and stress meter circuit is acquired by arriving line traffic control with external stress
Equipment connects.
The construction usage method of the utility model is：A kind of shaped steel stress meter, in use, first according to intensity of shaped steel etc.
Grade chooses corresponding fixing device, one and the equal-sized notch of stress meter is then opened on shaped steel, then answer assembled
In power meter peace side to the notch of shaped steel, stress meter is fixed finally by weld seam.
The operation principle of the utility model is：String wire in stress meter by varying strength stress when the frequency vibrated not
Together, the size for the internal force that stress meter is subject to can be conversed according to the vibration frequency of string wire.Fixing device passes through by rectangle to circle
Shape it is excessive, internal force suffered on shaped steel indentation, there section is transmitted to section as on circular stress meter, so as to accurate
Measure stress meter suffered by internal force size.
The beneficial effects of the utility model are：It is consistent when shaped steel stress meter is installed to above shaped steel with shaped steel, appearance
Face is smooth, is not easy to destroy in construction；It is simple in structure, be easily installed, engineering practicability it is strong, and stress meter main shaft and shaped steel internal force
Effect overlapping of axles, the internal force suffered by shaped steel can accurately be measured.
Description of the drawings
Fig. 1 is the structure diagram of the utility model.
Marginal data：(1)-fixing device；(2)-attachment device；(3)-stress meter；(4)-wire guide.
Specific embodiment
The utility model is described further below in conjunction with the accompanying drawings.
As shown in Figure 1, the utility model include a kind of shaped steel stress meter, it by fixing device (1), attachment device (2), should
Power meter (3), wire guide (4) composition；The fixing device (1) is and building materials ad eundem other steel outer end and shaped steel to be measured
Welding, inner end are connected with attachment device (2), and outer end configuration is rectangle, and inner end shape is circle, to transmit from shaped steel
Internal force, and be directed on stress meter (3)；The attachment device (2) is connecting stress meter (3) and fixing device (1)；Institute
The stress meter (3) stated be vibratory stress gauge, the stress intensity collected by the vibration frequency identified sign for measuring string wire；Institute
The wire guide (4) stated is the outlet of stress meter data circuit, and stress meter circuit is connected by arriving line traffic control with external stress collecting device
It connects.
The utility model is described in detail in above example, and the scope of protection of the utility model is with claims
Subject to.
