Abstract
Description
Technical Field
[0001] The invention relates to a sealing device for on-site detection of air tightness of building exterior windows and a use method thereof, belonging to the technical field of on-site detection of air tightness of exterior windows. Background Art
[0002] Building exterior windows are an important part of the building envelope, playing the role of lighting, sun protection, ventilation, waterproofing and sound insulation. Data show that the energy loss through doors and windows accounts for 45% to 50% of the building's energy consumption, and exterior windows have become a weak link in my country's building energy conservation. With the application of new technologies and new materials, higher requirements have been put forward for the performance of exterior windows in civil buildings. Air tightness is an important indicator among the various performances of building exterior windows, which has a direct impact on watertightness, thermal insulation and sound insulation.
[0003] In order to fully achieve the goal of "new urban buildings implementing a building energy-saving standard of no less than 65%", the current building design standard "Public Building Energy-Saving Design Standard" GB50189-2015 clearly stipulates in 3.3.5 that the air tightness of building exterior windows should meet the following requirements: (1) The air tightness of exterior windows of buildings with more than 10 floors should not be lower than level 7, that is, the unit seam length 1.0 ≥ q1 [m 3 / (m·h)]>0.5, unit area 3.0≥q2[m 3 / (m 2 h)]>1.5; (2) The air tightness of the exterior windows of buildings with less than 10 floors should not be lower than Grade 6, that is, the unit seam length 1.5≥q1[m 3 / (m·h)]>1.0, unit area 4.5≥q2[m 3 / (m 2 ·h)]>3.0; In addition, 5.1.3 of the "Code for Acceptance of Quality of Building Decoration and Renovation Projects" GB50210-2001 and 6.2.2 of the "Code for Acceptance of Quality of Building Energy-saving Projects" GB50411-2007 clearly stipulate that the air tightness of the building's exterior windows must be re-inspected or physically inspected on site before the final acceptance to ensure that the air tightness of the building's exterior windows meets the relevant energy-saving design requirements.
[0004] At present, more and more attention is paid to the air tightness of building exterior windows, and the on-site inspection work is increasing year by year, and the requirements are also more stringent. The current "On-site Inspection of Building Exterior Windows" JG / T211-2007 in my country clearly stipulates that transparent plastic film (thickness ≥ 0.2mm) must be used for sealing during the inspection process. However, during the on-site air tightness inspection process, there are many sandy walls, and it is difficult to ensure the sealing degree by relying solely on plastic film; some building exterior windows have waterproof films on their surfaces, which further increases the difficulty of sealing and seriously affects the additional penetration and the accuracy of the measurement results. In the actual air tightness inspection process, the sealing plate is often small in size, which makes it difficult to meet the on-site inspection requirements. After the inspection, the removal of the sealing plate is difficult, time-consuming and labor-intensive, which seriously affects the efficiency of the air tightness inspection of building exterior windows. Summary of the invention
[0005] The purpose of the present invention is to provide a sealing device for on-site detection of air tightness of building exterior windows and a method of use, so as to overcome the deficiencies in the prior art.
[0006] The technical solution of the present invention is a sealing device for on-site detection of air tightness of building exterior windows, which is a spliced pressure frame formed by connecting four or more sealing strips.
[0007] Furthermore, a bolt hole is provided in the middle of the sealing strip, a latch plate is provided at one end of the sealing strip, a card hole is provided on the latch plate, a side plug hole and a rear plug hole are respectively provided at the other end of the sealing strip, and the side plug hole and the rear plug hole are perpendicular to each other, and a locking device is provided at the end of the sealing strip at the intersection of the side plug hole and the rear plug hole.
[0008] Furthermore, the locking device includes a mounting hole opened on the end of the sealing strip, two arc-shaped bosses are symmetrically arranged in the mounting hole, a gap is reserved between the two arc-shaped bosses, and a rotary pin is installed in the mounting hole. The rotary pin is composed of a knob, a rotary rod and a buckle from top to bottom. Limiting bosses are symmetrically arranged on the outer diameter of the rotary rod, and a spring is sleeved on the rotary rod between the limiting boss and the knob.
[0009] At the same time, the present invention also provides a method for using the sealing device for on-site detection of air tightness of building exterior windows. First, the wall of the building exterior window is marked and positioned according to the position of the bolt holes on the spliced pressure frame and holes are drilled. Then, a transparent plastic film with a thickness of ≥0.2 mm is used to cover the exterior window. Then, according to the actual size of the building exterior window, a sealing strip is used to connect to form a spliced pressure frame, so that the spliced pressure frame can be pressed on all sides of the transparent plastic film. Then, expansion bolts are inserted into the bolt holes on the spliced pressure frame and the drilled holes on the wall and tightened, so that the spliced pressure frame is tightly pressed on the transparent plastic film. Finally, the periphery of the transparent plastic film is sealed with transparent tape to complete the sealing work of the building exterior window. After the entire building exterior window is sealed, the on-site air tightness detection of the building exterior window can be carried out.
[0010] In the above method, when connecting the sealing strips, adjacent sealing strips on the same straight line are connected by inserting the latch piece into the rear socket and are locked and fixed by a locking device; adjacent sealing strips in the vertical direction are connected by inserting the latch piece into the side socket and are locked and fixed by a locking device.

A locking device is provided at the intersection of the side plug hole 8 and the rear plug hole 9 at the end of the sealing strip 1. The locking device includes a mounting hole provided at the end of the sealing strip 1, two arc-shaped bosses 12 are symmetrically provided in the mounting hole, a gap is reserved between the two arc-shaped bosses 12, a rotary latch is installed in the mounting hole, and the rotary latch is composed of a knob 10, a rotary rod 14 and a buckle 13 from top to bottom, a limiting boss 15 is symmetrically provided on the outer diameter of the rotary rod 14, and a spring 11 is sleeved between the limiting boss 15 and the knob 10 on the rotary rod 14.
[0021] See also Figure 1 and Figure 6 , the method for using the sealing device for on-site detection of air tightness of building exterior windows is adopted. First, the wall of the building exterior window is marked and positioned according to the position of the bolt hole 7 on the spliced pressure frame 2 and a hole is drilled. Then, a transparent plastic film 3 with a thickness of ≥0.2 mm is used to cover the exterior window. Then, according to the actual size of the building exterior window, a sealing strip 1 is used to connect to form a spliced pressure frame 2, so that the spliced pressure frame 2 can be pressed on all sides of the transparent plastic film 3. Then, the expansion bolts 11 are inserted into the bolt holes 7 on the spliced pressure frame 2 and the drilled holes on the wall and tightened, so that the spliced pressure frame 2 is tightly pressed on the transparent plastic film 3. Finally, the periphery of the transparent plastic film 3 is sealed with a transparent tape, and the sealing work of the building exterior window can be completed. After the entire building exterior window is sealed, the on-site air tightness detection of the building exterior window can be carried out.
[0022] In the above method, when connecting the sealing strips 1, adjacent sealing strips 1 on the same straight line are connected by inserting the latch piece 5 into the rear plug hole 9, and are locked and fixed by a locking device; adjacent sealing strips 1 in the vertical direction are connected by inserting the latch piece 5 into the side plug hole 8, and are locked and fixed by a locking device. When the locking device is used to lock the adjacent sealing strips 1, the knob 10 is rotated to drive the rotary rod 14 to rotate together. When the limiting boss 15 on the rotary rod 14 rotates to the reserved gap between the two arc-shaped bosses 12, the buckle 13 can be pressed downward to make the buckle 13 snap into the snap hole 6 on the latch piece 5, thereby locking and fixing the adjacent sealing strips 1 together. Due to the presence of the spring 11, the spring 11 applies a constant pressure to the buckle 13, ensuring that the buckle 13 cannot be loosened from the snap hole 6 without external force, thereby achieving an anti-slip effect.
[0023] In summary, the present invention has a simple structure and is flexible and convenient to use. The spliced pressure frame 2 can be adjusted according to the size of the building's exterior windows, and can ensure that the spliced pressure frame 2 can be pressed around the transparent plastic film 3, so that the transparent plastic film 3 and the wall form a reliable seal, thereby improving the accuracy of the on-site air tightness measurement results of the building's exterior windows.
