A wall panel with an adjustable aspect ratio and an actual measurement room

Abstract

The invention discloses a length-width ratio-adjustable wallboard and an actual measurement room, and belongs to the field of buildings for experiments. The wallboard is formed by a plurality of wallboard units via sequential splicing along the length direction, wherein each wallboard unit comprises a panel, a length board, a width board and a hinge; through adjusting the distances between sub-panels, the sub-panels can be separated to form mounting spaces for mounting the length boards and the width boards, so that the lengths of the panels are increased, and on the contrary, the lengths of the panels can be decreased; and through adjusting the distances between sub-length boards, the sub-length boards can be separated to form mounting spaces for mounting the width boards, so as to increase the width of the panels, and on the contrary, the widths of the panels can be decreased. Therefore, the invention can provide the actual measurement room capable of changing the height-width ratiosof the houses according to the experimentally detected lengths and widths of the to-be-adjusted wallboards, so as to compare and research the influences, on the roof wind pressure distribution, of the walls with different height-width ratios, thereby saving the experimental steps, reducing the cost and improving the correctness of the measured data.

Description

technical field [0001] The invention relates to the technical field of experimental buildings, in particular to a wallboard with an adjustable aspect ratio and a test room. Background technique [0002] Wind load is one of the important structural design loads of building structures. Many wind disaster surveys show that the damage caused by low-rise buildings accounts for more than half of the total losses, and the destruction and collapse of low-rise buildings with a large number of areas in wind disasters and the casualties caused by them are the main reasons for the huge losses caused by wind disasters. Since the 1970s and 1980s, the wind load problem of low buildings has attracted great attention from wind engineering workers and architects. [0003] The architectural shape and roof geometry of low-rise houses, including the height-to-width ratio, plane size, roof slope, roof form, etc. These factors can change the airflow pattern around the building and have a signifi...

AI Technical Summary

Problems solved by technology

So far, most of the wind pressure measurement and wind tunnel test research on low-slung houses has been carried out around various types of roofs. Due to the limitation of conditions, the influence of the height-to-width ratio of the house on the wind load is studied. When using this method, it is often necessary to establish multiple measured houses with different aspect ratios on site, and then conduct comparative inspections. Using this method for comparative inspections is not only low in efficiency and high in cost, but also due to the location of multiple houses with different aspect ratios. There are also large differences in the measurement results due to different locations.
