Description
[technical field]
The utility model relates to a kind of negative-pressure air-flow that utilizes and detects the aging device of curtain wall fluid sealant.
[background technology]
Building curtain wall is made up of panel and support system, opposing body structure can have certain displacement ability or self have certain deformability, does not bear the building external revetment of the suffered effect of agent structure.Waterproof is the Essential Performance Requirements of curtain wall, divides by waterproof type, is divided into injecting glue waterproof and constructional waterproofing.Injecting glue waterproof adopts fluid sealant the gap filling between panel or between panel and receipts sapwood material, stops rain leakage to indoor.
Because fluid sealant is a kind of high-molecular organic material, the fluid sealant of curtain wall between the certain time limit rear panel of use there will be aging situation, and as surface fine crack be full of cracks out-of-flatness, time serious, the phenomenons such as fracture or defect appear in fluid sealant, make curtain wall occur seepage, have a strong impact on buildings and use.
Existing curtain wall detection technique, for the season cracking situation of fluid sealant, is also limited to visual method.Because curtain wall gap is many and mutually through, when indoor discovery seepage, be often difficult to determine breakthrough, the fluid sealant of a certain scope can only be removed, again note fluid sealant behind clean injecting glue face, gap, efficiency is low, and causes waste that is artificial and material.
Also have and utilize seepage flow fluid mechanics to detect the aging new technology of curtain wall fluid sealant, but owing to need detect under hydraulic pressure effect, must apply extra pressure to pick-up unit prevents pick-up unit under hydraulic action, departing from curtain wall surface, so that stationary installation forms airtight cavity, the scope of application limits to some extent.
[utility model content]
The purpose of this utility model is to overcome the deficiencies in the prior art part, adopt negative-pressure air-flow detection technique, plus external applied load is not needed just can fixing the closing with cavity of implement device to detect so that realization is quick, there is provided a kind of structure simple, cost is low, easy to detect, detection time is short, novel curtain wall fluid sealant degradation detecting device applied widely.
The purpose of this utility model is achieved in that
A kind of negative-pressure air-flow that utilizes detects the aging device of curtain wall fluid sealant, it is characterized in that it comprises utilizes principle of negative pressure to be adsorbed on detecting device outside curtain wall panel voluntarily, a closed cavity is formed in described detecting device, described detecting device is provided with the detecting device vacuum meter for measuring display detecting device internal vacuum, described detecting device is connected with forevacuum tank by pipeline, pipeline is provided with the vacuum degree regulator of band valve, and forevacuum tank is connected with vacuum pump.
Utilize negative-pressure air-flow to detect the aging device of curtain wall fluid sealant as above, it is characterized in that being sealed with soft colloid between described detecting device and curtain wall.
Utilize negative-pressure air-flow to detect the aging device of curtain wall fluid sealant as above, it is characterized in that described forevacuum tank is provided with the forevacuum tank vacuum meter detecting forevacuum tank internal vacuum.
The beneficial effects of the utility model have:
One, the vacuum detector edge of negative-pressure air-flow detection fluid sealant aging equipment uses soft colloid to seal, square, rectangular parallelepiped, right cylinder can be made by the shape of detected object owing to adopting principle of negative pressure vacuum detector and other is irregularly shaped, different curtain wall panels and fluid sealant surface type of attachment thereof can be adapted to.Soft colloid (plasticine) is coated in bottom and curtain wall fluid sealant junction seal, vacuum detector is equivalent to vacuum cup, easily fixes, and can be adsorbed on curtain wall surface voluntarily, does not need plus external applied load or facility can form airtight cavity.
The vacuum acquirement devices such as two, negative-pressure air-flow detects the vacuum detector of fluid sealant aging equipment or claims sucking disk outer-shell to be connected with vacuum regulator, forevacuum tank access vacuum pump, vacuum detector or claim sucker and forevacuum tank all vacuum meter to be housed.Open vacuum pump vacuum governor the vacuum tightness of forevacuum tank is regulated at-3000Pa, then access detecting device.During detection, detecting device inner sealing chamber vacuum degree maintains-3000Pa, if fluid sealant is in normal operating conditions, its vacuum tightness remains unchanged; If fluid sealant is aging, produce be full of cracks, even if its crackle is very small, but because bottom communicates with air, under atmospheric pressure effect, gas also can be infiltrated by bottom and form negative-pressure air-flow, and air current flow can make detecting device internal vacuum produce significant change, can judge that it is aging.
Three, the utility model structure is simple, and easily fixing, applied widely, cost is low, easy to detect, and detection time is short.
[accompanying drawing explanation]
Figure l is structural drawing of the present utility model;
Fig. 2 is the placement schematic diagram of device of the present utility model on curtain wall.
[embodiment]
As shown in Figure 1, a kind of negative-pressure air-flow detects fluid sealant aging equipment, it is characterized in that it comprises the vacuum detector 1 utilizing principle of negative pressure to be adsorbed on curtain wall panel (comprising the sealing glue-line of detection) outside voluntarily, a closed cavity 2 is formed in described detecting device 1, cavity 2 is provided with the detecting device vacuum meter 3 for detector for measuring 1 internal vacuum, described detecting device 1 is connected to forevacuum tank 5 by pipeline 4, pipeline 4 is provided with the valvular vacuum degree regulator 6 of band, and forevacuum tank 5 is connected with vacuum pump 7.
The utility model regulates the vacuum tightness in cavity 2 to keep stable by the vacuum degree regulator 6 of band valve in real time, monitoring the change of vacuum tightness in cavity 2, judging fluid sealant season cracking situation by observing detecting device vacuum meter 3.Pipeline 4 other end is connected with forevacuum tank 5, forevacuum tank 5 is also provided with the vacuum tank vacuum meter 9 detecting internal vacuum, can control the vacuum tightness of forevacuum tank 5 inside after opening vacuum pump 7 on demand.
As shown in Figure 1 and Figure 2, vacuum detector 1 of the present utility model can be square, rectangular parallelepiped, right cylinder and other is irregularly shaped.Be sealed with the soft colloid 8 of different-thickness between cavity 2 and curtain wall, adapt to curtain wall panel 10 and sealing glue-line 11 operating mode thereof of different connection form.
As shown in Figure 2, when the utility model is according to curtain wall sealing structure glue ageing management, vacuum detector 1 is placed on curtain wall panel 10 (comprising the sealing glue-line 11 of detection) outside, vacuum detector internal vacuum maintains-3000Pa, if fluid sealant is unaged, when being in normal safe state, even if there is atmospheric pressure acting force, but because local resistance loss coefficient convergence is infinitely great, bottom also airless penetrates into vacuum detector 1 inside, and in detecting device 1, vacuum tightness does not change.If there is catabiosis, even if its be full of cracks degree is also very small, local resistance loss coefficient is very large, under atmospheric pressure effect, air-flow all can be had to infiltrate vacuum detector 1 from micro gap, detecting device internal vacuum changes immediately, thus can Quick curtain wall fluid sealant whether normal operating conditions.
