Description
TECHNICAL FIELD
[0001] The utility model relates to the field of building outer window sealing detection, especially relates to a sealing device for building outer window air tightness on-site detection. BACKGROUND
[0002] The building outer window air tightness on-site detection is a detection process of forming a static pressure box by using a sealing device, a surrounding structure and an outer window, blowing air from the static pressure box to the two sides of the detection object through a wind supply system to form a positive and negative pressure difference, and then measuring and calculating the detection result by a detection system. The sealing device and the surrounding structure form the static pressure box, and the connections should be well sealed. The sealing device can be easily combined, and the connection with the surrounding structure should also have sufficient rigidity.
[0003] The traditional method is to paste high-grade plastic cloth around the inner wall of the window to achieve sealing requirements. The authorized announcement No. CN204357268U discloses a building outer window on-site air tightness experimental on-site sealing device on May 27, 2015, and specifically discloses a sealing device for building outer window air tightness on-site detection. SUMMARY
[0004] The utility model aims at the deficiency of prior art, provides a sealing device for building outer window air tightness on-site detection.
[0005] The technical scheme of the utility model is implemented in the following way:
[0006] A sealing device for on-site testing of the airtightness of building exterior windows includes walls, windows, roof slabs, and floor slabs. Sealing gaskets are installed around the window openings on the interior walls. These gaskets are connected to airtight covers, which are then pressed together to form a sealing frame. Sealing plates are connected to the four corners of the sealing frame. Sealing shaft support lugs are installed on the sealing plates, connecting to the sealing shaft. A sealing shaft sleeve is fitted onto the sealing shaft, connecting to an upper support rod. The other end of the upper support rod is rotatably connected to a sealing adjustment bolt via a sealing pressure bearing. The sealing adjustment bolt is threadedly connected to a lower support rod, the other end of which is connected to a support shaft. The set consists of a support shaft sleeve, a support shaft connected to a support shaft lug, a support shaft lug connected to a support shaft lug base plate, a support shaft lug base plate connected to a sliding sleeve, a sliding sleeve connected to an adjustable upper square tube, an upper square tube base plate connected to an upper square tube base plate, an upper square tube base plate pressed against the roof panel via an upper anti-slip pad, a bearing seat connected to a support pressure bearing, a support pressure bearing connected to a support adjustment bolt, a support adjustment bolt threadedly connected to a lower round tube, a lower round tube base plate connected to a lower round tube base plate, and a lower round tube base plate pressed against the roof panel via a lower anti-slip pad.
[0007] Preferably, the upper end of the support adjusting bolt is provided with a support adjusting bolt retainer.
[0008] Preferably, the upper end of the sealing adjusting bolt is provided with a sealing adjusting bolt retainer.
[0009] Preferably, the sliding sleeve is threaded with a locking screw, which is tightly connected to the upper square tube.
[0010] Preferably, the contact surface between the top square tube bottom plate and the top anti-slip pad is provided with anti-slip texture.
[0011] Preferably, the contact surface between the bottom plate of the lower cylindrical tube and the lower anti-slip pad is provided with anti-slip texture.
[0012] This utility model has the following advantages:
[0013] 1. The sealing device used for on-site testing of the airtightness of the building's exterior windows involves pressing the sealing frame against the airtight cover using the corresponding sealing gasket. A wrench is used to clamp and rotate the sealing adjustment bolt, increasing the distance between the upper and lower support rods. The friction between the lower top round tube base plate, the lower anti-slip pad, and the floor slab, as well as between the upper top square tube base plate, the upper anti-slip pad, and the roof slab, is transmitted through the upper top square tube, the lower top round tube, and the support adjustment bolt to the sliding sleeve. The sliding sleeve then transmits this force to the support shaft hanger base plate. The support shaft hanger base plate, through the support shaft hanger, support shaft, support shaft sleeve, lower support rod, sealing adjustment bolt, upper support rod, sealing pressure shaft sleeve, sealing pressure shaft, and sealing pressure shaft support hanger, transmits the force to the sealing pressure plate. The sealing pressure plate then transmits this force to the sealing frame, applying pressure to tightly seal the airtight cover, sealing gasket, and interior wall surface. This method does not damage the wall surface, nor does it peel off the interior decorative layer. It eliminates the cost of construction repairs and is reusable. Attached Figure Description
