Relevant regulations by " Code for design of timber structures " GB 50005-2003, tooth plate connected node to the tooth plate that has indentation (indentation tooth plate) that uses present embodiment carries out extension test, and with the tooth plate that do not have indentation (indentation tooth plate not as a comparison case, the tooth plate of this Comparative Examples is except that not having the indentation, its material and other structural parameters are with the tooth plate of present embodiment), the tooth plate connected node to external import M20 tooth plate carries out extension test as a comparison in addition.Each test result writes down as following table:
| The tooth plate type | The node peak load, KN | Plate tooth ultimate bearing capacity, MPa | 0.38mm slippage place node rigidity, KN/mm | Peak load place node rigidity, KN/mm |
| The indentation tooth plate | 20.84 | 1.69 | 30.77 | 15.03 |
| Indentation tooth plate not | 18.29 | 1.38 | 35.36 | 15.85 |
| The M20 tooth plate | 23.22 | 1.81 | 51.41 | 33.28 |
Annotate: the structural type of node is that load is parallel to wood grain, and is parallel to the tooth plate main shaft.
Payload values in the table and rigidity value are the average of one group of specimen test value.
According to GB, the surperficial net area (A) of plate tooth ultimate bearing capacity test value=ultimate load/tooth plate.Minimum value/coefficient k in plate tooth ultimate bearing capacity (P)=tooth ultimate bearing capacity test value; To without flame treatment, the dimension stock of moisture content≤15%, k=1.69+0.24r; The ratio of r-dead load standard value and mobile load standard value, 1.0～5.0; If r＜1.0 or＞5.0 o'clock, then get r=1.0 or 5.0.
Rigidity value in the table is the secant rigidity value.
By test result as can be seen, the plate tooth ultimate bearing capacity of the tooth plate that has an indentation of the present utility model is apparently higher than indentation tooth plate not, prove absolutely that the indentation of plate tooth in the structure design of the present utility model has significantly strengthened the resistance to plucking ability of plate tooth, has also improved the bearing capacity of tooth plate connected node; Indentation tooth plate connected node of the present utility model the rigidity at 0.38mm slippage place and peak load place will be significantly less than not indentation tooth plate and M20 tooth plate, rigidity is more little, node just can absorb more energy when same load, illustrate that indentation tooth plate of the present utility model has made full use of the intensity of tooth plate steel plate, the anti-seismic performance of this indentation tooth plate connected node obviously is better than not indentation tooth plate and M20 tooth plate.
