Glodon GTJ Civil Engineering Quantity is an important task before the grid is established after the creation of the project- Floor settings
In the past, when the reinforcement calculation and the civil engineering calculation were calculated separately, we generally carried out the reinforcement calculation first, and used the structural elevation, which was convenient for the layout of the components and the elevation setting of the elementsAfter the reinforcement calculation is completed, it will be imported into the civil engineering calculation, and the floor elevation will be modified to the building elevation, and the calculation of civil engineering decoration components will be carried out.
Since GTJ2018, we have been discussing the issue of floor table setting, and practice has proved that here we have to correctly set the floor height and floor number according to the floor elevation on the structural drawings, as for why we do not use the building elevation to set the floor height, welcome to discuss in the comment area.
Can multiple layers be set up as one layer?
Or is the level set incorrectly?
What about not even setting the floor elevation and manually modifying the elevation of the element throughout the process of establishing the element?
What is the influence of the floor height setting in the process of civil engineering modeling?
The following is explained one by one according to the impact on the takeoff.
Software default height 3More than 6 meters for ultra-high formwork, 3The starting height of 6 meters is the bottom of the layer, and it also meets the requirements of the quota rules of most provinces, so there is a requirement for the elevation of the bottom of the layer, if the setting is not correct, the engineering quantity calculation of the super-high template will be wrong.
According to the previous question, the multi-layer is set to one layer, then the engineering quantity of the super-high formwork will be calculated very much, and at the same time 3A 6-meter non-super-high formwork will also be undercounted. In the case of incorrect layer height settings and manual modification of the element level, the superelevation template is also incorrectly calculated, because there is a problem with the starting height, which is the case in real life. For example, I did a factory project before, with an east-west span of more than 360 meters, and an indoor floor of about 100 meters near the east exterior wall000, the indoor floor within 20 meters of the west exterior wall is -6000, the middle is an inclined plane, the outer walls on the north and south sides are shear walls, and the bottom elevation of each section is different, in this case, the super-high template should be calculated, and the bottom elevation is set to 000 or -600 is incorrect, and the calculation rules of the superelevation formwork can only be modified in the calculation settings to the floor slab that intersects or tangents to the bottom of the column.
It needs to be said that different provinces have different calculation rules for superelevation templates, such as Gansu Province in 3More than 6 meters is not segmented, height "36 and height 46 hours of how much engineering is how much engineering quantity, 46> Height" 36 o'clock unified according to the super high for 46 meters for quantity calculation.
The Inner Mongolia 2017 building decoration quota is calculated according to the contact area between the formwork and the concrete, and the ultra-high formwork is not calculatedShaanxi Province's 09 quota, the template is in accordance with more than 36 meters to calculate the super-high formwork, with the super-high part of the concrete engineering quantity "m" calculation;Some regions will also press 36 meters per 12 meter segment calculation (the software defaults to 1 meter segment, which can be modified by yourself).
These must be modified in the calculation settings in order to increase the amount correctly.
The ultra-high template is not an ultra-high increase fee, let alone a vertical transportation fee, the three are essentially different, and they all need to be priced, pay attention to the distinction according to the quota rules.
Similar to the super-high formwork, the bottom elevation software of the scaffold is obtained by default as the "layer bottom elevation", for the wall column where the outdoor floor is the slope and the different bottom elevation of the same layer, the engineering quantity obtained by the scaffold from the bottom elevation calculation by default is definitely wrong, and the software calculation settings need to be modified according to the actual situation of the project, as follows, the bottom elevation I still choose the floor slab that intersects or tangential with the bottom of the column.
Multi-layer setting to a layer will definitely affect the amount of calculation, first of all, the super-high template is wrong, the reinforcement of the column will definitely be less than the lap and encryption stirrups of the embedded part, and most of the components need to establish layering in the modeling process, which brings unnecessary trouble When the floor is set, the elevation setting error will of course also affect the takeoff, but some engineering projects have complex structures that can not be taken into account, at this time, it is necessary to pay more attention to the calculation settings and node settings of the software After modifying the calculation settings, the whole process of manually modifying the elevation is of course also possible, which is suitable for the inconsistent elevation of the components, and the above situations are often encountered when the unified floor elevation cannot be established, such as industrial buildings, such as the podium part of a residential building, as well as large public buildings with complex structures, etc. It does not mean that the calculation settings of the software must be modified, but we must understand the principle of Glodon GTJ software for calculating engineering quantities, and modify the calculation settings of the software in order to obtain the most accurate engineering quantities.
Software is just a tool, and the calculation needs to use your brain, thank you for reading.
