Method for reinforcing steel bar position determination and spatial model construction in building wall

Abstract

The invention discloses a method for reinforcing steel bar position determination in a building wall and comprises the following steps that: an infrared radiation device is fixed on the outer side ofthe wall body to shoot an infrared thermogram; according to a situation that a heat source range is shaded, the reinforcing steel bar position in the wall body is judged, a hydroelectric position is further designed, and slotting installation is carried out. The invention simultaneously provides a method for spatial model construction and comprises the following steps that: the infrared radiationdevice is simultaneously fixed on the necessary point of a building space, then, movement is carried out in the building space, the infrared thermogram and distance data are dynamically collected, andfinally, the collected data is converted into building space model data which contains reinforcing steel bar data. By use of the method, a complex measurement process is omitted, the complexity degree of an algorithm is greatly lowered, processing efficiency is high, an error ratio is low, the reinforcing steel bar position in the wall body can be directly obtained, and a modeling method which issimple in operation, easy in realization and accurate in data is provided for designers, especially designers, in the decoration industry so as to bring convenience for later-stage design, revision and display.

Description

technical field [0001] The invention relates to a method for determining the position of steel bars in a building wall and constructing a space model, and belongs to the technical fields of infrared technology, perspective technology and modeling. Background technique [0002] In the process of decorating a new family house, it is often encountered that the walls such as the kitchen exterior wall, the bathroom and the bedroom share the same wall, the balcony and the bedroom share the same wall, etc. The wall is waterproof and anti-collapse, and it is determined to be a reinforced concrete structure (also known as a reinforced concrete structure) at the initial stage of building construction. It is called steel-concrete structure), often the hydropower master can only rely on guesswork to excavate the hydropower tank on the wall according to the customer's requirements when he cannot predict the distribution of steel bars in the wall, and the hydropower tank that is often open...

[0002] In the process of decorating a new family house, it is often encountered that the walls such as the kitchen exterior wall, the bathroom and the bedroom share the same wall, the balcony and the bedroom share the same wall, etc. The wall is waterproof and anti-collapse, and it is determined to be a reinforced concrete structure (also known as a reinforced concrete structure) at the initial stage of building construction. It is called steel-concrete structure), often the hydropower master can only rely on guesswork to excavate the hydropower tank on the wall according to the customer's requirements when he cannot predict the distribution of steel bars in the wall, and the hydropower tank that is often opened by electric hammer equipment is due to There are many pre-buried steel bars when developers build houses, so they can only open the surface of the wall (the thickness of the surface is generally between 3-5cm) and cannot continue to dig deeper. The master can only choose to re-excavate at a nearby location or directly Ways to rebar cut off to keep working

The consequences of doing so are, first, affecting the progress of the construction, and second, leaving potential safety hazards due to changes in the steel-concrete structure of the wall

Without the drawings provided by the developer, the plumber cannot determine the distribution area of ​​the wall reinforcement and the density of reinforcement in the area

[0003] Similarly, for decoration designers, although they have the structural drawings of the house type, the internal steel bars of the walls are not marked on the drawings, which also has great constraints on the design
