Problems solved by technology

[0002] At this stage, tall girders and slabs are mostly identified through manual image checking. For large public buildings or other large-volume cast-in-place concrete projects, the number of structural drawings and the number of tall girders and slabs are large, and manual map recognition takes a lot of time and cannot be accurate. , no omissions, need to be improved urgently

Embodiment Construction

[0015] The present invention will be further described in detail below in conjunction with the examples.

[0016] 1. Load Calculation Method

[0017] Calculate according to JGJ130-2011 "Safety Technical Code for Fastener Type Steel Pipe Scaffolding in Building Construction".

[0018] 1.1 Calculation method of total construction load

[0019] (1) The composition of the load:

[0020] Average load = permanent load (reinforced concrete self-weight + template wood self-weight) × sub-item factor + construction uniform live load × sub-item factor Reinforced concrete self-weight = plate thickness (m) × 25KN / m3 (reinforced concrete when calculating the average load The specific gravity is 25KN / m3)

[0021] Self-weight of formwork wood: 0.3KN / m2 (the value is 0.3KN / m2 when calculating the average load)

[0022] Construction uniform live load: 3KN / m2

[0023] (2) Calculation of the thickness of bearing members with uniform distribution:

[0024] 1.2×(25M+0.3)+1.4×3≥15 to get M≥0.3...

Abstract

The invention relates to a high girder plate one-key identification method based on a BIM technology. The erection height of the high girder plate is 8m or above; the total construction load is 15 kN / m < 2 > or above, the concentrated line load is 20 kN / m or above, the floor or beam color in the model is changed through elevation between an upper layer plate and a lower layer plate in the model and REVIT API by utilizing C # language coding and limiting conditions in the model, and the floor or beam color is highlighted and displayed in the model. According to the method, a BIM model is utilized, C # language coding is utilized through REVIT API, tools for automatically identifying high girders, plates and other components defined in template supporting engineering are manufactured, one-key identification of the high girders and the plates is achieved, and an accurate basis is provided for compiling a high and large formwork construction scheme; and the identified high girder plate isvisually displayed to managers and workers in a three-dimensional manner, so that project field safety management is assisted.

Description

technical field [0001] The invention relates to the technical field of BIM technology for identifying loads of tall girder slabs, and specifically refers to a one-key identification method for tall girder slabs based on BIM technology. Background technique [0002] At this stage, tall girders and slabs are mostly identified through manual image checking. For large public buildings or other large-volume cast-in-place concrete projects, the number of structural drawings and the number of tall girders and slabs are large, and manual map recognition takes a lot of time and cannot be accurate. , No omissions, need to be improved urgently. Contents of the invention [0003] The technical problem to be solved by the present invention is to overcome the shortcomings of the prior art and provide a one-key recognition method for tall girder slabs based on BIM technology. [0004] In order to solve the above technical problems, the technical solution provided by the present inventio...
