Problems solved by technology

At present, the commonly used method is to first generate the bottom reinforcement according to the rules of uniform distribution of the bottom reinforcement, then arrange the trusses symmetrically, and then manually observe the positions of the bottom reinforcement and the truss, and manually delete the bottom reinforcement distributed under the truss. Low efficiency, low replacement rate of trusses, and irregular arrangement of bottom bars

Embodiment Construction

[0050] The present invention will be further described below in conjunction with drawings and embodiments. The terms "first", "second", "third", etc. are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0051] Such as figure 1 As shown, a laminated floor truss arrangement method, including

[0052] Step S1: Calculate the number of trusses required. In this application, calculate by formula (4):

[0053] Formula (4):

[0054] n_hj=CEIL(k / q);

[0055] Where n_hj is the number of trusses;

[0056] q is the maximum spacing allowed between trusses.

[0057] In the prior art, it is usually required that the distance between the truss and the plate edge is not greater than 300mm, and the spacing is not greater than 600mm. Therefore, n_hj=CEIL(k / 600)

[0058] In this step, the CEIL function is used to obtain the calculation. The function of the CEIL function is to return the smallest integer greater than or equal to ...

Abstract

The invention discloses a composite floor truss and a bottom bar arrangement method. The composite floor truss arrangement method comprises the steps of S2, calculating the number of distances betweentrusses, and specifically solving the number through the building of a loop algorithm and a screening function. According to the bottom bar arrangement method, the bottom bars and the trusses can beautomatically arranged according to rules through the sizes of prefabricated parts and the distances between reinforcing steel bars, the trusses and the bottom bars are symmetrically arranged and areuniform and attractive, the steel content of the concrete prefabricated parts can be effectively reduced, the production cost of the part is saved, and the design efficiency of the composite floor trusses and the bottom bars is greatly improved.

Description

technical field [0001] The invention relates to the field of building technology, in particular to a method for arranging a laminated floor truss and bottom reinforcement. Background technique [0002] Truss laminated floor is a common component of prefabricated buildings at present. In the component design stage, in order to reduce the steel content of the floor and reduce the cost of the component, the lower chord reinforcement of the truss will be used as the stress reinforcement, thereby reducing part of the bottom reinforcement in the same direction as the truss. Based on the existing rules, how to replace and how to arrange trusses and bottom bars are difficult problems for designers. At present, the commonly used method is to first generate the bottom reinforcement according to the rules of uniform distribution of the bottom reinforcement, then arrange the trusses symmetrically, and then manually observe the positions of the bottom reinforcement and the truss, and man...
