How Grilled quantities and drawings should be aware of the problem
First, do not be afraid, do not be intimidated by drawing a thick, steel sheet Foshan actually very simple, as long as you get down to seriously look at and easy to follow, but the first not to rush to get the drawing to pick up the drawings Pa map, I think first of all to see throughout the drawings are completely and see what you want to dig up some of the drawings is what is the pipe gallery, frames, ladders, etc., carefully look at the requirements of technical description of the drawings, there is every a marked, throughout the drawings to see if and where do not understand, you want to look around carefully in conjunction with, until understand this. Understand the future, do not rush to dig up map, to look at the drawings to be grilled specified node maps, to know what is the column strong axis, what is the weak axis of column, beam and read beam convergence, convergence of beams and columns combination node graph, also known as clear in some detail, such as cantilever: at one end of the beam and the column or beam steel pick, and the other end with the hinge beam, beam type / FL, then indicate left steel, beam type / FR indicating right steel pick. Draft requirements Grilled drawing quantities must be clear, to prepare for the future to know how the investigation was initially counted, not the same subheading in the draft must be clearly labeled, such as the amount of which is the framework for some, the amount of which is a joint platform some, as well as the draft of the type of steel Q235B, Q345B distinction must understand.
The following can be sequentially by number of drawings to Pa map, although it is a sequence diagram a steak, but when combined with grilled FIG also around, and do not count and do not count re-exposed. Beam Elevation in accounting do not have a fixed plan elevation drawings on, because the more intuitive in the accounting plan, the elevation in the count if in the accounting of weight, and in some elevation in elevation beam no details the plan, then the elevation to its accounting quantities, as everything is a plan view elevation 10m, 20m, 30m, 12m elevation and elevation there, and to its accounting quantities, but to pay attention to some details of the small platform there is no such level, this level do not have accounted for its engineering capacity in elevation, the small platform in the future plan in its accounting of quantities can be, in the accounting plan was relatively simple and intuitive and is not exposed. There is no plan in the accounting quantities cantilever bracing, so in elevation in accounting to project the amount of cantilever bracing.
When accounting plan is best not to be considered a plan even if the level of the ladder all the elevation, so easy to calculate weight and more trouble, for example, you forget this layer count ladder when the plane 10m of elevation, to the elevation of 20m layer also forget this layer ladder, then the ladder counted two most likely from 10m on 20m or 20m at 10m ladder ladder, two ladder is actually a ladder. After another count isochronous engineering, unified calculation ladders, so can not go to the same elevation rate test, not easy to count heavy dew is not easy to count, and to count the number of different ladder, there can be calculated the same quantities of a ladder, just after the number is multiplied by a ladder on it, and has been able to come up with a detailed accounting of the ladder after ladder, to avoid the accounting of a ladder to find a detail, counted after the close up the next count a ladder looking ladder detail, so can greatly improve the efficiency and accuracy of accounting.
When the length of the accounting column to pay attention to the column foot elevation, but also the thickness of the floor and lose column capitals plate column base plate thickness can be seen from the drawing, but no detailed drawings in capitals plate thickness, not the same column capitals have different thickness plate, the thickness from the junction diagram can be found. Foshan is steel gusset accounting accounting quantities in a difficult, so before accounting gusset plates must be read carefully to count the node in the node graph board. When accounting gusset plates, if rectangular gusset plates are not regular, and most graphically longest side broadside in a rectangular area of accounting, to identify what kind of steel beam is then, what is hinged beam, not the same beam the corresponding bearing beam is not the same node board are not the same, so the accounting node board also pay attention to the type of bearing beams corresponding, when the node node combination accounting board to be careful not to count the weight, but also the column node graph to distinguish between the top and the middle of the column to count, and the two beams at a height greater than 50 and less than 50 nodes map is not the same, should pay attention to distinguish to count.
It means the accounting quantities in some special way it works amount calculated manufacturing apparatus, such as when the accounting sector platform engineering, the way to its size and the number of manufacturing required angle ring mold calculated to prevent re looking for trouble in the future. End count all quantities can be based on standardized after accounting the number required over the probe H-beam, based on technical accounting measures Foshan steel erection reinforcement weight.
