Area calculation of architectural cheese bay window and protective railing


I don’t like cheese

.

I opened a new channel “architectural cheese”

.

Recently, I looked at the drawings and studied the bay window

.

There is still a lot of knowledge in it

.

First, I explained the term: bay window (bay window)   For windows protruding from the outer wall of the building, the sill of bay window (bay window) shall be only a part of the wall and have a certain height from the floor

.

According to code for calculation of building area of Building Engineering (gb2019) 1, the area of bay window (bay window) with height difference between sill and indoor floor less than 0.45M and clear height of structure more than 2.10m shall be calculated as 1 / 2 of the peripheral horizontal area of its enclosure structure

.

.

The building area shall not be calculated for the convex (floating) window with the height difference between the windowsill and the indoor floor less than 0.45M and the clear height of the structure less than 2.10m, and the convex (floating) window with the height difference between the windowsill and the indoor floor more than 0.45M

.

When it comes to bay windows, the protective railings must not be ignored

.

In 5.8.2 of the code for design of residential buildings (gb0096-2011), when setting bay windows, the following provisions shall be met: when the sill height is less than or equal to 0.45M, the protective height shall not be less than 0.9m from the sill surface

.

Basis: the bay window table with height less than or equal to 0.45M is easy to cause unconscious climbing, and its effective protection height shall be calculated from the bay window table, and the height shall not be less than 0.9m

.

When the clear height from the bottom of the openable window sash opening to the window top is less than 0.9m, protective facilities shall be provided at the opening

.

The protection height shall not be less than 0.9m from the windowsill surface

.

To sum up, the two regulations show that the opening leaf of the bay window can be touched in time and can be protected from the windowsill position; If it cannot be touched in time, it shall be pasted with windows for protection

.

At this time, at 12:36 a.m

on August 1, 2021, the registered supervision engineer checked the score on Friday, passed the exam, and was ready to write an article on the preparation strategy, praising more than 20 arrangements! I wish you all no insomnia and no hair loss in August! You can also take a look at the detailed structure of fine decoration of model rooms in other articles (I) what attention should be paid to the ceiling with light steel keel? Beamless floor = unscrupulous floor? Development and construction application – “complete five certificates” do you know? Finally, click “watching” below before you go!.
