横向天窗有不避风的和避风的两种类型。不避风的(见图1)适用于冷加工车间,常用折线形、拱形或三角形屋架;避风的适用于热加工车间,常用平行弦屋架,以便与通风采光天窗和挡风侧墙一起形成一个良好的避风井。本文着重讨论此类适用于热加工车间的横向天窗,亦即横向避风天窗(见图2)。以往的热加工车间大多沿用带挡风板的矩形天窗,亦即矩形避风天窗。这是一种上升式的天窗。它是在屋架上设置气楼而且大多采用寿命不长的石
There are two types of horizontal skylights that are not sheltered from wind and sheltered from wind. Non-sheltered (see Figure 1) is suitable for cold processing workshops, commonly used in the form of broken lines, arches or triangular roof trusses; sheltered wind is suitable for hot processing workshops, commonly used parallel string roof trusses, in order to form a good together with the ventilation skylights and windshield side walls Sheltered well. This article focuses on such horizontal transoms suitable for hot processing workshops, ie, lateral shelter windows (see Figure 2). In the past, most of the hot-workshops used rectangular windshields with wind deflectors, that is, rectangular wind-proof sunroofs. This is a rising sunroof. It is to set up gas buildings on the trusses and most of them use short-lived stones.
