Description

A curtain wall sealant aging detection device

【Technical field】

The utility model relates to a curtain wall sealant aging detection device.

【Background technique】

The building curtain wall is composed of a panel and a supporting structure system, which can have a certain displacement capacity relative to the main structure or a certain deformation capacity by itself, and is a building peripheral protective wall that does not bear the action of the main structure. Waterproofing is the basic performance requirement of curtain wall. According to the waterproofing method, it can be divided into glue injection waterproofing and structural waterproofing. Glue injection waterproofing is to use sealant to fill the gap between the panels or between the panels and the edge material to prevent rainwater from leaking into the room.

Since the sealant is an organic polymer material, the sealant between the panels of the curtain wall will age after a certain number of years of use, such as fine lines on the surface, cracks and unevenness, and in severe cases, the sealant will be broken or defective, making the Leakage occurred in the curtain wall, seriously affecting the use of the building.

The existing curtain wall detection technology is still limited to the visual inspection method for the aging and cracking of the sealant. Because there are many gaps in the curtain wall and they are connected with each other, when a leak is found indoors, it is often difficult to determine the leak point. Only a certain range of sealant can be removed, and the sealant is refilled after cleaning the gap injection surface, which is inefficient and causes manual and waste of material.

【Content of utility model】

The purpose of the utility model is to overcome the shortcomings of the prior art and provide a curtain wall sealant aging detection device with simple structure, low cost, convenient detection and short detection time.

The purpose of this utility model is achieved in that:

A curtain wall sealant aging detection device, characterized in that it includes a cup cover adsorbed on the outside of the curtain wall panel, a closed cavity is formed inside the cup cover, and a pipeline for filling the cavity with liquid is connected to the cup cover , the pipeline is provided with a switch and a flowmeter, and the cup cover is also provided with a pressure gauge for detecting the pressure of the liquid in the cavity.

The above-mentioned curtain wall sealant aging detection device is characterized in that a sealing rubber ring is provided between the cup cover and the curtain wall.

A curtain wall sealant aging detection device as described above is characterized in that the other end of the pipeline is connected to a liquid reservoir, the liquid reservoir is provided with a far-infrared liquid level controller, and the liquid reservoir is also connected to a proportional control valve and solenoid valves.

The above-mentioned curtain wall sealant aging detection device adjusts the pressure in the detection chamber in real time through the hydraulic control system to maintain a stable pressure value required by the design, and judges the aging and cracking of the sealant by observing the changes in the flow rate of the pressure gauge and the flow meter. Condition.

The beneficial effects of the utility model have:

1. Use sealing rubber rings around the edges of the curtain wall sealant aging detection device, and apply a pressure of not less than 15N to the detection device to fix it, preventing the detection device from detaching from the surface of the curtain wall under hydraulic pressure to form a closed cavity. When testing, the liquid pressure in the chamber adopts the maximum wind load design value (about 3-5KPa) required by the curtain wall design requirements. When the liquid flow fills the entire detection device, observe the changes in the flow rate of the pressure gauge and flowmeter. Within the selected time (for example, 30 seconds), if the flow rate into the pipeline is zero and the pressure remains stable, it means that the sealant layer is intact; if the flow rate is zero and the pressure changes slightly, it means that the sealant is aging and cracks appear; if The aging of the sealant is cracked, the crack is very small, no seepage flow velocity is formed, and the pulsation of the flow velocity can still judge its aging.

2. The curtain wall sealant aging detection device adopts the design of seepage fluid pressure according to 3-5KPa, which belongs to low-speed fluid, but the liquid pressure must be kept stable. The self-designed hydraulic control system of the utility model adjusts the pressure of the liquid in the liquid reservoir in real time, so that the liquid remains stable when it passes through the cavity of the detection device. Since the height of the liquid level of the liquid reservoir directly affects the pressure used by the detection device, the liquid level must be kept relatively stable. For this reason, a far-infrared liquid level controller is set above the liquid reservoir. When the liquid level drops, the output signal and the output flowmeter Give a signal to the proportional control valve, open the solenoid valve, and input the fluid with unstable pressure from the external or built-in hydraulic source to the liquid reservoir to keep the liquid level stable.

3. The utility model has the advantages of simple structure, low cost, convenient detection and short detection time.

【Detailed ways】

As shown in FIG. 1 , the curtain wall 100 is composed of a plurality of panels 101 , and the panels 101 are sealed with a sealant 102 .

As shown in Figure 2, a curtain wall sealant aging detection device includes a cup 1 adsorbed on the outside of the curtain wall panel (including the detected sealant seam), the cup 1 has a certain volume, so that the inside of the cup 1 can be used To hold a certain amount of liquid, a closed cavity 2 is formed in the cup cover 1, and the cup cover 1 is connected with a pipeline 3 for filling the cavity 2, and a switch 4 is provided on the pipeline 3 And a flow meter 5, the cup cover 1 is also provided with a pressure gauge 6 for detecting the pressure of the liquid in the cavity 2. A sealing rubber ring 7 is provided between the cup cover 1 and the curtain wall to ensure the sealing between the cup cover and the curtain wall panel (including the detected sealant joint), so that a closed cavity 2 is formed in the cup cover 1 .

As shown in Figure 2 and Figure 3, the other end of the pipeline 3 is connected with a liquid reservoir 8, the liquid reservoir 8 is provided with a far-infrared liquid level controller 81, and the liquid reservoir 8 is also connected with a proportional control valve 82 and an open solenoid valve 83.

The cup cover 1 of the present utility model can be a cube, a cuboid, a cylinder, and other irregular shapes.

According to the design requirements of the curtain wall, the design value of the maximum wind load that the curtain wall bears is used as the detection pressure in the utility model. In general engineering practice, the design value of wind load is less than 5KPa, so as a detection method, the seepage fluid pressure can be designed according to 3-5KPa, which belongs to low-speed fluid, but the liquid pressure must be kept stable. The utility model designs a hydraulic control system by itself to adjust the liquid pressure in the liquid reservoir in real time, so that the pressure of the liquid in the liquid reservoir can be kept stable when it enters the cavity 2 of the detection device through the switch 4 and the flow meter 5 . Since the liquid level height of the liquid reservoir 8 directly affects the pressure used by the detection device, it is required that the liquid level must remain relatively stable. For this reason, a far-infrared liquid level controller 81 is set up above the liquid reservoir 8. When the liquid level drops, the output signal and The output flowmeter gives a signal to the proportional control valve 82, and the electromagnetic valve 83 is opened to input fluid with unstable pressure from the external or self-contained hydraulic source 9 to the liquid reservoir 8 to keep the liquid level stable.

The surrounding edge of the curtain wall sealant aging detection device uses a sealing rubber ring 7 to apply a pressure of not less than 15N to the detection device to fix it, preventing the detection device from detaching from the surface of the curtain wall under the action of hydraulic pressure, and forming a closed cavity 2 . The maximum wind load design value of the curtain wall required by the design is used for calculation during the detection. The liquid pressure in the cavity is about 3-5KPa. When the liquid flow fills the entire detection device, observe the changes in the flow rate of the pressure gauge 6 and the flow meter 5. If within the selected time (for example, 30 seconds), the flow rate into the pipeline is zero and the pressure remains stable, it means that the sealant layer is intact; if the flow rate is zero and the pressure changes slightly, it means that the sealant is aging and cracks appear; if The aging of the sealant is cracked, the crack is very small, no seepage flow velocity is formed, and the pulsation of the flow velocity can still judge its aging.
