The device adopts a self-balancing loading system and cooperatively uses a loading and a data collection systems to have the advantages of simple operation, convenient loading and accurate and reliable detected data.
Description
Technical field
The utility model relates to a kind of on-the-spot novel test device that loads of existing structure beam slab stress performance that detects.
Background technology
Along with expanding economy, the fundamental construction of China has entered the newly-built stage of developing simultaneously with the transformation maintenance, and a large amount of engineering structures are faced with transforms maintenance, and wherein old-age group building building (room) lid or small-sized highway bridge generally adopt contignation.Because damage in use appears in part beams and slabs primitive architecture structural drawings disappearance, part beams and slabs, the part beams and slabs was once reinforced repair process, thereby being difficult to accurately estimate its stress performance, on-the-spot load test is that can the existing beams and slabs of check satisfy the most effective means that safe handling requires.At present temporary no suitable test unit, general with the method simulation loading of stacking sack cement or yellow sand, fragment of brick or discharging water by skin, can not carry out the overall process failure test, and workload is big, the load metering is inaccurate, has influenced the precision of beams and slabs security performance evaluation result.
Summary of the invention
The purpose of this utility model is the defective at above-mentioned conventional method, a kind of on-the-spot load testing machine that is used for estimating beams and slabs stress performance in existing building structure or the bridge structure is provided, this installation cost is low, adds carried convenient, and measurement data accurately and reliably.
The purpose of this utility model is achieved through the following technical solutions: the on-the-spot novel test device that loads of a kind of existing structure beam slab stress performance, comprise reaction beam, loading beam, reinforcing pull rod, seat angle and band steel steel plate, wherein seat angle and band steel steel plate are separately positioned on the beams and slabs, the two ends of lower surface, and become dismountable fixedly connected by coupling arrangement, four jiaos of reaction beam are passed through four reinforcing pull rods and are connected with seat angle, loading beam is placed on the span centre position of beams and slabs, when measuring, lifting jack places between reaction beam and the loading beam, and lifting jack is connected with oil pump and loads.
The on-the-spot novel test device that loads of above-mentioned a kind of existing structure beam slab stress performance also comprises the steel cushion block, is arranged between reinforcing pull rod and the seat angle, and its effect is to guarantee well interlock between reinforcing pull rod and seat angle.
The on-the-spot novel test device that loads of above-mentioned a kind of existing structure beam slab stress performance also comprises displacement meter, is arranged on beams and slabs both ends and span centre position, is used to measure the amount of deflection of beams and slabs.Concrete members or rebar surface paste foil gauge and measure its stress distribution.
This use is novel to have following beneficial effect:
(1) can carry out at the scene, avoid the existing structure beams and slabs is tested from delivering to testing laboratory after take out at the scene, thereby avoid huge workloads such as removal, lifting, transportation;
(2) form self equilibrium systems by reaction beam, loading beam, reinforcing pull rod, seat angle, the additional reaction frame that the scene need not be special, testing cost significantly reduces;
(3) can be used oil pump, lifting jack loading, and without the method simulation loading that the conventional on-site load test is stacked sack cement, yellow sand, fragment of brick or discharged water by skin, add carried convenient, loading velocity is controlled, and load numerical value is accurate;
(4) be used lifting jack and data acquisition system (DAS), can carry out the overall process failure test of beams and slabs, continuously, load one displacement curve in the accurate recording loading procedure, record cracking load, yield load, failing load and corresponding displacement.
The self-equilibrating loading system is adopted in this device design, is used to load and data acquisition system (DAS), and is simple to operate, add carried convenient, detect data accurately and reliably, can write down the overall process load-displacement curve, thereby the security and the normal usability of beams and slabs are made correct evaluation.Be applicable to the safety assessment before beams and slabs is transformed in existing building structure or the bridge structure, the safety assessment of damaged component, the check and the assessment of beams and slabs consolidation effect.
