Embodiment Construction

[0030] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings.

[0031] A method for determining the shape parameters of a fixed sun visor net, the shape of a fixed sun visor net, such as figure 1 As shown, the surface is evenly opened with array distribution unit meshes 1, and each unit mesh 1 is surrounded by four oblique sheet units 2 with the same shape, and adjacent oblique sheet units 2 are rotationally symmetrical along the connecting line; the shape of the oblique sheet units 2 is determined The method is as follows:

[0032] 1) Model parameterization

[0033] Such as figure 2 As shown, a cube coordinate system whose length, width, and height are A, B, and H is established, the length of the projection of the oblique sheet unit along the height H direction in the end face of the cube is C, and the length of the transverse plate of the oblique sheet unit is X / 2. ...

Abstract

The invention discloses a method for determining fixed sunshade net shape parameters. The surface of the fixed sunshade net is uniformly provided with unit meshes distributed in an array. Each unit mesh is enclosed by four oblique slice units of the same shape. A method of determining the shape of the oblique slice unit specifically comprises the following steps of first, model parameterization; second, parameter selection optimization; third, performance indicator design; fourth, light transmittance feature calculation; and fifth, shape parameter determination. According to the method of determining the sunshade net shape parameters, the optical parameters of the sunshade net are acquired through three-dimensional modeling and lighting simulation calculation according to extreme lighting simulation experiments of cloud day or sunny day, so that the sunshade net shape parameters are determined. The method is applicable to different latitudes and shape design of sunshade nets of different lighting regions, and has high practicability and applicability.

Description

technical field [0001] The invention relates to the field of construction, in particular to a method for determining the shape parameters of a fixed sunshade net. Background technique [0002] With the development of my country's construction industry, a large number of civil buildings have been constructed, and various types of glass lighting roofs (glass roofs, glass skylights) and glass curtain walls have also begun to be widely used in hotels, restaurants, stations, airports, commercial cities, and department stores. , exhibition halls, gymnasiums, museums and hospitals, etc. [0003] Existing glass daylighting roofs and curtain walls are generally composed of glass and metal structures, and the glass surface has the characteristics of strong heat transfer and high thermal transmittance, which has a great impact on indoor thermal conditions; glass daylighting roofs and curtain walls have become architectural The most active and sensitive part of material heat exchange an...
