Abstract
A method for testing wind pressure resistance of film-coated glass comprises the following steps: step one, confirming that a curtain wall test piece meets design requirements; secondly, breaking the filmed glass, but ensuring that the whole glass or glass fragments cannot fall off, knocking the central part of the glass by toughened glass, and cutting a crack in the middle of the glass by using a glass cutter for semi-toughened or ordinary glass, wherein the length of the crack is not less than 200 mm; and step three, repeatedly pressurizing and detecting, wherein the detected pressure difference takes a standard value of 0.4 time of the designed wind load as an average value, 1/4 of the average value as amplitude, and positive and negative pressure fluctuation detection is carried out, the fluctuation pressure period is 5-7 s, and the fluctuation frequency is not less than 10 times. The method is a test method for evaluating the wind pressure resistance of the broken filmed glass, clearly provides a concept and a test method of the residual wind pressure resistance of the filmed glass after being broken, and is beneficial to quantitative evaluation of the safety performance of the filmed glass after being broken.
Description
Technical field
The present invention relates to a kind of pad pasting glass test method of security performance after broken of evaluating, a kind of test method testing pad pasting glass wind pressure resistant strength within the broken rear short time.
Background technology
At present, building glass scene Filming Technology has been obtained for a certain degree of development, building glass adhesive cover products is the most perfect, and formulated a series of product standard, but still suffer from many problems, topmost, the safety of pad pasting engineering is the most sufficiently studied, such as, the main purpose of pad pasting is that " variable interval " after preventing toughened glass crushing comes off, but, how many blast can be born after pad pasting toughened glass crushing, the edge structure impact the most how problem on pad pasting glass safety, all lacks in-depth study.
So far, not for pad pasting glass evaluation methodology of resisting wind press capacity after broken, the existing evaluation to pad pasting glass resisting wind press capacity is also only limitted to resisting wind press capacity during pad pasting glass good working condition, its shortcoming is: (1) cannot reflect pad pasting glass security performance after broken, is unfavorable for pad pasting the evaluation of resisting wind press capacity after toughened glass crushing；(2) cannot reflect that edge constructs the impact of security performance after pad pasting toughened glass crushing.
Summary of the invention
It is an object of the invention to provide the resisting wind press capacity test method of a kind of pad pasting glass, the existing evaluation to resisting wind press capacity during pad pasting glass good working condition will be solved and cannot reflect the technical problem of pad pasting glass security performance after broken.
For achieving the above object, the present invention adopts the following technical scheme that the resisting wind press capacity test method of a kind of pad pasting glass, it is characterised in that step is as follows: step one, confirmation curtain wall test specimen meet design requirement；Step 2, break pad pasting glass into pieces, but must ensure that glass is overall or glass fragment can not come off, safety glass should tap the centre of glass, half tempered or simple glass should the standardized crackle of portion's diamant in glass, crack length is no less than 200mm；Step 3, repeatedly pressurizeing detection, detection pressure differential, with 0.4 times of designed wind load standard value as meansigma methods, with the 1/4 of meansigma methods as wave amplitude, carries out positive/negative-pressure surge detection, and the surge pressure cycle is 5s～7s, and fluctuation number of times is no less than 10 times；Step 4, following situations occurs for the moment, off-test；1) glass entirety comes off；2) adhering film to glass tear；3) edge a part or whole part connects disconnection；4) glass fragment comes off.
The diaphragm of described pad pasting glass should be intact, and pad pasting glass should come off without glass fragment, and pad pasting glass edge connecting structure should be intact.
Compared with prior art the invention have the characteristics that and beneficial effect: the invention provides the evaluation methodology remnants wind pressure resistant strength test method of a kind of pad pasting glass resisting wind press capacity, a kind of method of testing evaluating pad pasting glass resisting wind press capacity after broken, to determine pad pasting glass, especially pad pasting safety glass security performance in the short time after broken.
The present invention clearly proposes the pad pasting glass broken rear remaining concept of wind pressure resistant strength, test method, is conducive to the security performance after crushing pad pasting glass to carry out quantitative assessment, can reflect pad pasting glass security performance after broken.
The present invention which kind of edge of more specific judgement can construct the security performance after crushing pad pasting glass advantageously, and the engineer applied of pad pasting glass is had great importance.
Detailed description of the invention
The step of resisting wind press capacity test (the i.e. building glass safe pad pasting remnants wind pressure resistant strength test) method of this pad pasting glass is as follows.
Step one, confirmation curtain wall test specimen meet design requirement.
Step 2, break pad pasting glass into pieces, but must ensure that glass is overall or glass fragment can not come off, safety glass should tap the centre of glass, half tempered or simple glass should the standardized crackle of portion's diamant in glass, crack length is no less than 200mm.
Step 3, repeatedly pressurizeing detection, detection pressure differential, with 0.4 times of designed wind load standard value as meansigma methods, with the 1/4 of meansigma methods as wave amplitude, carries out positive/negative-pressure surge detection, and the surge pressure cycle is 5s～7s, and fluctuation number of times is no less than 10 times.This step is exactly the wind pressure resistant strength of the broken rear pad pasting glass of test, i.e. pad pasting glass remnants wind pressure resistant strength.
Step 4, following situations occurs for the moment, off-test；1) glass entirety comes off；2) adhering film to glass tear；3) edge a part or whole part connects disconnection；4) glass fragment comes off.
In above-mentioned steps, the diaphragm of described pad pasting glass should be intact, and pad pasting glass should come off without glass fragment, and pad pasting glass edge connecting structure should be intact.
The detection device used in above-mentioned steps should meet the requirement of existing national standards " building curtain wall airtight, watertight, resisting wind press capacity detection method " GB/T 15227 resisting wind press capacity detection device, the installation of test specimen should be consistent with engineering, the stickup of safe pad pasting and the connecting structure with frame should meet design requirement, test specimen answers maintenance 2 weeks, and in double glazing, abate answered after maintenance completes by the glass of non-pad pasting.
