Abstract
The utility model discloses a kind of charger of single-beam static test, comprise multiple load-on module be made up of the lumps of wood and sandbag, in a load-on module, the horizontal and vertical lumps of wood base being arranged in sequence with many lumps of wood respectively and being formed, the lumps of wood is provided with a boring every certain distance, fixed by boring bolt at the horizontal lumps of wood and longitudinal lumps of wood, the top of lumps of wood base is provided with one deck sandbag.The utility model facility simple to operate, can ensure again the safety of staff simultaneously, makes by adopting the mode adding loading multistage loadings, be applicable to work as and load the loading structure that the number of plies reaches more than 3 layers, load mode is more firm, and unlikely landing ensures the safety of field officer.<b/>
Description
Technical field
The utility model belongs to dead-load detection apparatus field, is specifically related to a kind of charger for single-beam static loading experiment.
Background technology
Bridge static loading test is by the assigned address of static load action on bridge, then the parameter such as static displacement, static(al) strain, crack of bridge structure is tested, thus to a kind of loading test that the serviceability of bridge structure under load action and use ability are made an appraisal.Static test uses maximum, modal fundamental test in Test on Bridge Loading.
Bridge structure static test, generally can be realized by the loading equipemtn of gravity or other types.The loading procedure of static test starts from scratch progressively to increase progressively, until till predetermined load.Static test understands the important means of architectural characteristic, not only directly solving the static problem of structure with it, exactly when carrying out dynamic test of structure, generally also first will carry out static test, to measure structure dependent parameter.
Utility model content
Problem to be solved in the utility model is: for above-mentioned the deficiencies in the prior art, provide a kind of structure simple, add carried convenient and be suitable for high-rise loading, ensure emphatically the charger of the single-beam static loading experiment of experimental site worker safety.
The technical solution adopted in the utility model is: a kind of charger of single-beam static loading experiment, comprise multiple load-on module be made up of the lumps of wood and sandbag, in a load-on module, the horizontal and vertical lumps of wood base being arranged in sequence with many lumps of wood respectively and being formed, the lumps of wood is provided with a boring every certain distance, fixed by boring bolt at the horizontal lumps of wood and longitudinal lumps of wood, the top of lumps of wood base is provided with one deck sandbag.
Further, the described lumps of wood is of a size of 5 × 10 × (300 ~ 400) cm, and the distance of adjacent two borings is 40cm.
Further, the quality of described sandbag is 0.8 ~ 1.2 ton.
The beneficial effect that the utility model produces is: the utility model facility simple to operate, the safety of staff can be ensured again simultaneously, the mode adding loading multistage loadings is made by adopting, be applicable to work as and load the loading structure that the number of plies reaches more than 3 layers, load mode is more firm, unlikely landing, ensures the safety of field officer.

Fig. 1 is the structural representation of load-on module;
Fig. 2 is the structural representation of lumps of wood base;
Fig. 3 is the structural representation of charger;
Fig. 4 is the loading diagram of static test.
Embodiment
Below in conjunction with accompanying drawing, the utility model is further described.
As shown in Figure 1, the utility model is a kind of charger of single-beam static loading experiment, and this device forms primarily of multiple load-on module 5, and each load-on module 5 comprises lumps of wood base and is arranged on the sandbag 2 on lumps of wood base.
As shown in Figure 2, lumps of wood base is made up of the lumps of wood 1 that six transverse and longitudinals are staggered, each all adopts the lumps of wood 1 being of a size of 5 × 10 × (300 ~ 400) cm, the every 40cm of every root lumps of wood 1 bores the circular hole 3 of a 1.0 ~ 1.1mm, lumps of wood base adopts M12 × 120 stainless steel bolt 4 to reinforce, and the large I of grid formed adjusts with the size of piling loading.
As shown in Figure 3, when carrying out load test, by testing the loading length of single-beam and loading the quantity that width chooses load-on module 5, and on lumps of wood base, place the sandbag 2 that quality is 0.8 ~ 1.2 ton.Sandbag 2 is directly placed in the place contacted with beam face, placement of multiple layers load-on module 5 successively on sandbag 2.
As shown in Figure 4, when measurement single-beam length is the load-carrying ability of 4400cm, carry to each 4.5m cloth of from left to right with span centre by adopting, it is 9m that cloth carries overall length, direction across bridge cloth carries length 1.9 ~ 2.1m, the loaded seat lumps of wood adopts 5 × 10 × 300cm, employing average quality is the sandbag of 1 ton, test is evenly load, load intensity is 134kN/m, totally 9 meters long, 1.8 meters wide, amount to 120 tons, about can place 18 sandbags for every layer, load 7 layers, when being wherein loaded into last one deck, each placement 6 sandbags about span centre, modes of emplacement is the same with other layer, under this trial load effect, span centre maximal bending moment is 11847kNm.The load effciency coefficient of this test is 11847/11892.44=0.996, meets the area requirement of 0.95 ~ 1.05 of communications and transportation ministerial standard " highway bridge load-bearing capacity detecting appraisal code " (JTG/T J21-2011) defined.
Claims (3)
