Embodiment Construction

[0046] This embodiment takes the two-flail movable room frame as an example to describe in detail the wind load simulation test method for the main frame of the box-type movable room of the present invention. The windward side and the leeward side of the main body of the truss are respectively provided with three uprights 1 at equal intervals, one on each side, one central upright in the middle between the sides, and three oblique beams with an inclination angle of 20° on the top of the corresponding truss. °. The middle part of the frame between the inclined beams is the ridge. The height of the fence of the movable room is 2.6 meters, that is, the effective height of the columns is 2.668 meters, and the distance between the columns is 2 meters.

[0047] In the specific test process of this embodiment, the installation and fixation of the steel structure movable room frame is carried out at first, and the movable room frame is fixedly installed on the horizontal test site, b...

Abstract

The invention relates to a wind load simulation test method for a mobile house with a double-slope roof in the technical field of wind resistance detection of a mobile house. The wind load of the mobile house is converted into the wind load applied to the windward side by a transverse wind load simulation loading device and a wind suction simulation loading device. The equivalent static load of the multi-point loading on each main load-bearing component on the north wind side is carried out step by step multi-point loading test to measure the displacement and strain of each stressed beam column under various wind loads, and then evaluate and verify the activity room The wind resistance performance of the structure simplifies the loading method and graded loading process in the test process, and carries out graded loading and graded tests for the main load-bearing components. The safety of the test process is high, and it also solves the problem of wind resistance of large-scale movable houses. The problem of limited implementation of tests and wind tunnel tests.

Description

technical field [0001] The invention relates to the technical field of wind resistance detection of a steel structure frame of a prefab house with a double-slope roof, in particular to a wind load simulation test method for a prefab house with a double-slope roof. Background technique [0002] The steel structure double-slope roof mobile house is mainly based on standardized design, industrial processing and assembly installation to achieve special needs such as combination expansion, repeated disassembly and use, and plays an important role in field living, temporary troops and emergency support. Usually, mobile homes will face strong winds when they are used in the field, border defense and coastal areas. Therefore, it is necessary to focus on and investigate the structural wind resistance during design and product testing. However, it is difficult to choose a suitable site and a suitable wind force for the actual wind resistance test. Completion of relevant tests, wind tu...
