As shown in fig. 2, this embodiment provides a method for measuring and calculating a reinforcement of an assembled precast column, including:
step one, defining digital information of prefabricated column components, including component names, section width/height, slurry sitting height, prefabricated height, post-cast height, longitudinal bar information, stirrup information, field embedded steel bar engineering quantity and up/down encryption range;
adjusting the calculation setting and the node setting of the prefabricated column, calculating the engineering quantity of the reinforcement of the prefabricated column, wherein the engineering quantity of the reinforcement of the prefabricated column is only calculated by the prefabricated column, and the engineering quantity of the reinforcement of the post-pouring part comprises calculation parameters of the reinforcement and calculation parameters of the on-site embedded reinforcement;

and step four, estimating the engineering quantity of the prefabricated column steel bars, including summarizing, calculating, finishing and selecting one or more prefabricated column primitives, obtaining the engineering quantity of the steel bars, editing information according to the type and the diameter of the steel bars, and displaying the stirrups of the post-cast part of the prefabricated column at the corresponding positions of the column in real time according to the calculated arrangement mode.
In some embodiments, the modeling entity of the prefabricated column consists of three units including a post-casting unit, a prefabricated unit and a sitting pulp unit and is displayed, but the attributes of the three units are combined together for display in the attributes, and the display mode that the attributes do not need to be distinguished from the unit display enables a user to avoid the trouble of switching the unit for multiple times.
Name of the component: default is YZ-n, named according to the name of the prefabricated column given in the drawing, and the prefabricated column corresponds to the floor plan when being conveniently drawn.
Cross-sectional width/height: according to the input of a drawing, the width/height of the cross section of the prefabricated column plays a role in all three unit bodies of the prefabricated column, and the overlooking cross section size of the whole prefabricated column is determined.
Setting the height of the mortar: the height of the column bottom slurry setting part determines the height of the slurry setting unit and the initial position of the prefabricated unit.
Prefabrication height: the height of the concrete of the prefabricated column processed part in a factory determines the height of the prefabricated unit and the initial position of the post-cast unit.
Post-pouring height: the height of the part of the precast column which needs to be poured with concrete again on site is also the range of the stirrups which need to be calculated when the precast column is poured on site. The height is calculated through the top-bottom height difference of the prefabricated column, the sitting-down-size is reduced, and the prefabricated height is calculated, so that a user does not need to input manually.
Longitudinal bar information: the input of the longitudinal bar information can be input according to the original longitudinal bar input mode of the pillar. However, the longitudinal bars of the prefabricated column are prefabricated directly in the engineering, so that even if the longitudinal bars are input, the longitudinal bars cannot be calculated again. The longitudinal bars are input here to facilitate drawing of the post-cast area stirrups of the prefabricated column.
Stirrup information: the stirrup information (including the stirrup in the node area) has no change with the stirrup input mode of the original frame column. In the prefabricated column, only stirrups (including column stirrups and joint area stirrups) within the height range of the post-cast part are calculated during calculation, and stirrups of the prefabricated part and the grout sitting part are not calculated.
Embedding reinforcing steel bars in the field: and inputting the information of the embedded steel bars, and automatically calculating the steel bars embedded in the lower-layer column or the prefabricated column through calculation setting and node setting.
Upper/lower encryption range: the private attributes of the primitives are used for controlling the range of the upper and lower encryption zones of the column stirrup. If the encryption zone range is set for the primitive at this point, the encryption zone is calculated according to the set length at that point. However, for the prefabricated column, the encryption area is usually prefabricated in advance in the factory, so that only the calculation of the encryption area range is performed for the on-site post-cast part, that is, even if the encryption area length is input here, the encryption area is usually not calculated.
In some embodiments, the calculating the parameters of the stirrup in the second step comprises:
starting the initial position of the stirrup of the post-cast part of the precast column from the top end of the precast part;
when the number of the stirrups of the prefabricated column is calculated, rounding the number of the stirrups;
the length setting atlas of the stirrup encryption area of the post-cast part of the precast column has a standard.
In some embodiments, the calculating parameters of the on-site embedded steel bars in the second step include:
the connection mode of the upper-layer longitudinal bars and the lower-layer longitudinal bars of the prefabricated columns is connected with the steel bars of the lower-layer columns in a mode of reserving sleeves at the bottoms, and the calculation of the on-site embedded steel bars is realized in a mode of combining calculation setting and node setting;
the cast-in-place post of on-spot pre-buried indulges the muscle in lower floor or prefabricated post and stretches into the sleeve of this layer of prefabricated column bottom, confirm that embedded steel stretches into prefabricated post sleeve length according to the reinforcing bar diameter, increase the node that on-the-spot embedded steel stretches into prefabricated post promptly in the node setting, the length that the node the inside stretched into prefabricated post part can set up to d1, add the length d 1's that an on-the-spot reinforcing bar stretches into prefabricated post setting table again and stretch into different lengths in the sleeve of prefabricated post according to the diameter correspondence layer length that gives in the calculation setting.
Calculating parameters of stirrups: the prefabricated column only calculates the stirrups of the post-pouring part, and common stirrups calculation parameters are set for the characteristics.
The initial position of the stirrup of the post-cast part of the precast column starts from the top end of the precast part, but there is no accurate way in conventional calculation and atlas provisions, so the embodiment sets the part as adjustable content for self-adjustment by the user.
Prefabricated post stirrup radical calculation mode, the result that the stirrup calculated is an integer certainly, but in the reality often all is the decimal according to the result that interval and column height calculated, just need do the root of stirrup and get the integer calculation this moment, and this embodiment provides the several different modes of getting the integer and supplies the user to select from the line.
The length setting atlas of the hooping encryption area of the post-cast part of the precast column has standards, each precast column primitive in each project is different, the precast column primitive is set according to the requirements of the atlas, and the mode which can be set by a user is reserved.
Calculating parameters of the on-site embedded steel bars: the connection mode of the upper and lower layer longitudinal bars of the prefabricated column is different from that of the cast-in-place column, and the form of a sleeve reserved at the bottom is used for being connected with the steel bars of the lower layer column. This requires the design of such new connection means. The embodiment provides a mode that calculation setting and node setting supplement each other to realize the calculation of the on-site embedded steel bars.
The field embedded longitudinal bar in the cast-in-place post of lower floor or the prefabricated post needs to stretch into the sleeve of this layer of prefabricated column bottom, and the different telescopic length that corresponds of diameter of reinforcing bar is just different, and this embodiment provides one kind and confirms the calculation method that the embedded reinforcing bar stretches into prefabricated post sleeve length according to the reinforcing bar diameter. The node that on-spot embedded steel bar stretched into precast column is increased in the node setting promptly, and the length that the node inside stretched into precast column part can set up to d1, adds the length d 1's that an on-spot reinforcing bar stretched into precast column setting table again in the calculation setting, and the diameter that the on-spot embedded steel bar just given in the calculation setting corresponds layer length and stretches into different lengths in the sleeve of precast column like this.
If the length given in the drawing is not directly not taken, the length required in the drawing can be directly input at the position d1, for example, 8 × d or 500.
The d1 value in the calculation setting table is not required to input a number, and if the length required to extend into the precast column is the height of the set slurry plus the corresponding length of the sleeve or a direct multiple of the longitudinal ribs, a calculation formula such as 20+8 x d can be input in the calculation setting d1 setting table for representation.
In some embodiments, the cast-in-place column at the bottom of the prefabricated column in the third step comprises two different construction forms, and the cast-in-place column reinforcing steel bars can extend into the prefabricated column when extending into the prefabricated column and can not extend into the prefabricated column to be anchored at the top of the column.
In some embodiments, when the column is cast-in-place at the top of the column in the third step, the length of the longitudinal bar of the column, which extends into the cast-in-place column, is reserved, the steel bar of the cast-in-place column on the upper part is directly lapped with the steel bar reserved from the prefabricated column on the spot, and the actual position of the steel bar of the cast-in-place column at the top of the prefabricated column is set.
Prefabricating a cast-in-place column at the bottom of the column: the sleeve is left at the bottom of the prefabricated column, and the cast-in-place column steel bar can stretch into the prefabricated column to stretch into the prefabricated column and cannot stretch into the prefabricated column to be anchored at the top of the column. This embodiment gives two different configurations of the cast-in-place column top rebar, one that is extendable and one that is not extendable. The green fonts in the two calculation nodes can be input by self, and the same d1 value extending into the prefabricated column sleeve can be redefined and modified in the calculation rule (the calculation setting is the same as the field embedded steel bars).
Prefabricating a cast-in-place column at the top of the column: prefabricated post is indulged the muscle and is reserved the length that stretches into cast-in-place post, and the cast-in-place post reinforcing bar in upper portion is direct to carry out the overlap joint with the reinforcing bar that prefabricated post was reserved out behind the scene and calculate, and this embodiment provides the node and sets up the real position of the cast-in-place post reinforcing bar in prefabricated capital portion, and the user can self-define the initial position who sets up the vertical muscle of cast-in-place post. Wherein the corner ribs and the edge ribs can be arranged separately.
