Problems solved by technology
[0006] In order to solve the above-mentioned technical problems, the present invention provides a device for measuring instantaneous internal pressure of a building structure, to solve the problem that the internal pressure measuring device generally selects a building model for testing, and then calculates and obtains the experimental results through corresponding formulas. The building model is used as the experimental object, and the results obtained are theoretical values, and the existing internal pressure measurement device cannot control the size of the air inlet after the simulated window is damaged, so the data obtained from the experiment cannot truly reflect the building after the door and window are damaged. The pressure change inside the object, the accuracy is low, and the problem that it cannot truly reflect the test results

The invention discloses an instantaneous internal pressure measuring device for a building structure, relates to the technical field of internal pressure measuring devices, and solves the problem thatthe existing internal pressure measuring device generally selects a building model for testing and cannot truly reflect a test result. The instantaneous internal pressure measuring device for the building structure comprises an air inlet simulation mechanism and a window damage simulation mechanism. The air inlet simulation mechanism is movably connected to the middle part in the shell; and the window damage simulation mechanism is inserted into the simulation window frame in an interference-fit manner. The device can be directly placed beside the window inside the building to carry out an internal pressure measurement experiment, the size of the simulated window damage notch can be adjusted through the window damage mechanism, after the air inlet simulation mechanism is started, the change of the pressure in the building after air flow enters the building through the window damage simulation mechanism can be simulated, the numerical value can be measured by designing the air pressuremeasuring instrument in the building and the change of the air pressure in the building after the window is damaged can be truly simulated.
Description
technical field [0001] The invention belongs to the technical field of internal pressure measuring devices, and more specifically relates to an instantaneous internal pressure measuring device for building structures. Background technique [0002] When the window, glass, door, window or curtain wall of the building structure is suddenly damaged under the action of natural strong wind, the wind will flow into the building from the damaged hole, causing a large change in the wind pressure inside the building, and the wind flowing into the building The wind-induced internal pressure will also have a greater impact on the comfort of the indoor occupants and the stability of the pendants in the house. In order to study the above man-made or natural strong wind environment, the instantaneous internal pressure of the building structure increases sharply The influence of the inner layer structure and the distribution of wind pressure, the internal pressure measurement experiment is ...
