Description
Technical field
The present invention relates to the detection models and its making of technical field of ships more particularly to a kind of ship key node position
Method.
Background technology
Ship partial structurtes in shipping will produce larger stress, and the stress generated for key area must be had
The transmission and release of effect ensure that structure is not present such as right-angled intersection, three pieces of plate welding positions to three point alignments of this key area
Installation deviation is just particularly important, and corresponding shipyard can all select to check and check that center is aligned with template when building.
But same key node position can generally be directed to the same section in this way due to the case where there are more thickness combinations
Point makees multiple models according to plate thickness difference, and sometimes up to more than ten, such model was both inconvenient to carry, and is easy mixed
Confuse, omit and make troubles to construction.
Invention content
The purpose of the present invention is to overcome the above shortcomings and to provide a kind of detection model of ship key node position and its systems
Make method, the measurement of a key node can be completed by only doing a template for the same key node position.
The object of the present invention is achieved like this：
A kind of production method of the detection model of ship key node position, it is comprised the following steps that：
The first step：Design standard detects model：It chooses three kinds and refers to plate thickness t1, t2 and t3, the plate thickness of inclined plate is t1, the plate of riser
Thickness is t2, and the plate thickness of transverse slat is t3, t1=21.5mm, t2=14.5mm, t3=24.5mm, in the case where ensureing center line alignment,
Model is detected according to reference to board thickness design；It is a that regulation detection model, which measures the distance between side and riser, inclined plate and transverse slat it
Between angle be@；
Second step：Calculate the detection corresponding a values size of model：Calculation formula is a=0.5 (t1/sin@+t3/tan@- t2), i.e. t1
=21.5mm, t2=14.5mm, t3=24.5mm, when@=45.38 °, detection model measures the distance between side and plate thickness a=30；
Third walks：Calculate other different plate thickness a value sizes：For other combination plate thickness, when being detected with the detection model, core
Corresponding a values are calculated, a values in the case of this all plate thickness of CM node locations is calculated this, measurement table is made；
4th step：Make detection sample：1：1 is detected the material cutting of sample, is ready for 1：1 drawing confirms detection sample
The precision and accuracy of making, and third party is allowed to confirm；
5th step：Construction：The installation of the same CM nodes, inspection work are completed according to qualified detection model and measurement table is examined
Make.
A kind of detection model of ship key node position, the detection model side are plane, and another upper lateral part is one
Inclined-plane, the inclined-plane are bonded completely with inclined plate, and a groove is equipped with below inclined-plane, and transverse slat stretches into groove, and groove section below is flat
Face referred to as measures side, parallel with riser.
Compared with prior art, the beneficial effects of the invention are as follows：
It is the configuration of the present invention is simple, easy to use, it chooses and refers to plate thickness, make standard form according to reference to plate thickness, construction can root
According to qualified template and measurement table is examined, only the installation of the same CM nodes completed with a general model, check work, avoided

Lower making step：
1, design standard detects model：It chooses three kinds and refers to plate thickness t1, t2 and t3, the plate thickness of inclined plate 1 is t1, the plate thickness of riser 3
For t2, the plate thickness of transverse slat 2 is t3, there is the plate thickness of ten kinds of specifications in conventional shipbuilding, wherein seven kinds in zonule compared with
Few application, remaining three kinds of plate thickness by maximum probability are applied to, these three plate thickness are 21.5mm, 14.5mm and 24.5mm, are being ensured
In the case that center line is aligned, model 4 is detected according to reference to board thickness design, 4 side of detection model is plane, on the other side
Portion is an inclined-plane, which is bonded completely with inclined plate 1, and a groove is equipped with below inclined-plane, is stretched into groove convenient for transverse slat 2, groove
Section below is plane, referred to as measures side, parallel with riser 3.
For ease of subsequently measuring, it is a, inclined plate 1 and transverse slat 2 that now regulation detection model 4, which measures the distance between side and riser 3,
Between angle be@.
2, it calculates and detects the corresponding a values size of model, a=0.5 (t1/sin@+t3/tan@- t2), i.e. t1=21.5mm, t2=
14.5mm, t3=24.5mm, when@=45.38 °, detection model measures the distance between side and plate thickness a=30.
3, other different plate thickness a value sizes are calculated：For other combination plate thickness, when being detected with the detection model 4, core
Corresponding a values are calculated, such as t1=21.5mm, when t2=16.0mm, t3=24.5mm, the calculating according to the corresponding a values of detection model above is public
Formula obtains a=29.25mm to calculate, and calculates this values in the case of this all plate thickness of CM node locations, i.e. table 1, as follows：
