Description

Technical Field

[0001] This utility model belongs to the field of building curtain wall air tightness testing technology, specifically a sealing frame for building curtain wall air tightness testing. Background Technology

[0002] Driven by the "dual carbon" goals, the construction industry is accelerating its transformation towards green and low-carbon development. As an important component of the building's external envelope, the airtightness of the building curtain wall directly affects the building's thermal insulation performance and energy consumption level. According to statistics, the energy loss caused by insufficient airtightness of the curtain wall can account for 15% to 25% of the building's total energy consumption. Therefore, accurate airtightness testing has become a key link in ensuring the energy-saving effect of buildings.

[0003] Traditional building curtain wall airtightness testing sealing frames mostly adopt a structure of rigid materials spliced ​​together with elastic sealing strips. In practical applications, such frames have exposed several technical bottlenecks: First, the sealing performance is limited by material aging and installation errors. Ordinary rubber sealing strips are prone to hardening and cracking under the influence of environmental factors such as ultraviolet rays and high and low temperatures, leading to sealing failure. At the same time, small bumps or unevenness on the curtain wall surface or installation tilt can prevent the sealing strip from being evenly compressed, forming leakage channels. Second, the fixing methods have limitations. Although bolt anchoring or mechanical clamps can provide stable fixing, drilling holes in the curtain wall structure is required during installation, which is not only time-consuming and labor-intensive, but may also damage the waterproof and anti-rust coating of the curtain wall.

[0004] Therefore, a sealing framework for testing the air tightness of building curtain walls is proposed to address the above issues. Utility Model Content

[0005] To address the problems mentioned in the background art, this utility model provides a sealing frame for testing the air tightness of building curtain walls. It has the advantages of improving air tightness by inflating and expanding to adapt to the curtain wall surface, achieving non-destructive and rapid installation using suction cups and strong magnetic blocks and adapting to curtain walls of various materials, and precisely controlling the fixing force and position by combining displacement adjustment components.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a sealing frame for airtightness testing of building curtain walls, comprising a frame body, a sealing plate installed on the frame body, an airbag sealing assembly installed on the frame body, and an adsorption fixing assembly and a magnetic fixing assembly respectively installed on the frame body;

[0007] The airbag sealing assembly includes an airbag strip located on the rear side of the frame body. Part of the airbag strip is embedded in the frame body. The airbag strip is connected to an embedding tube. One end of the embedding tube is connected to a pipe joint. The pipe joint is connected to an air guide tube. The air guide tube is connected to an inflation pump.

[0008] The adsorption and fixing component includes a first fixing plate fixed at the four corners of the frame body, the first fixing plate is connected to a first displacement adjustment component, and the first displacement adjustment component is connected to a suction cup.

[0009] The magnetic fixing assembly includes a second fixing plate fixed at the four corners of the frame body, the second fixing plate is connected to a second displacement adjustment assembly, and the second displacement adjustment assembly is connected to a strong magnetic block.

[0010] Preferably, a pressure detection connection port is installed on the sealing plate on the front side of the frame body, and two pressure detection probes are installed on the inner wall of the frame body.

[0011] Preferably, the left and right sides of the frame body are fixedly connected with symmetrically arranged fixing ears, and fixing holes are provided on the fixing ears.

[0012] Preferably, a pressure relief valve is installed on the sealing plate on the right side of the frame body.

[0013] Preferably, both the first displacement adjustment component and the second displacement adjustment component are composed of a threaded rod, a threaded tube, and a connecting bearing. The threaded rod is threadedly connected to the threaded tube, and the end of the threaded tube is connected to a suction cup or a strong magnetic block through the connecting bearing.

[0014] Preferably, a locking bolt is installed on the threaded tube, with the end of the locking bolt abutting against the threaded rod.

[0015] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0016] 1. The airbag sealing assembly of this utility model significantly improves the sealing performance of the sealing frame through the coordinated work of the airbag strip, embedded tube, pipe joint, air guide tube and air pump. Before testing, the airbag strip is inflated by the air pump. After the airbag strip expands, it can fit tightly against the curtain wall surface. Even if there is some unevenness or installation error on the curtain wall surface, the expanded airbag can adaptively fill the gap. Compared with traditional sealing strips, its sealing effect is better, which can effectively reduce gas leakage during the testing process and improve the accuracy of air tightness test data.

[0017] 2. This utility model forms a diversified fixing system by combining adsorption fixing components and magnetic fixing components with fixing ears on the frame body. Among them, the adsorption fixing components use the negative pressure adsorption force generated by the suction cup to achieve fast and stable installation without damaging the glass curtain wall surface, which is particularly suitable for glass curtain wall inspection with high requirements for surface integrity. The magnetic fixing components use the magnetic force of strong magnets to firmly adhere to metal curtain walls, and the installation process does not require additional tools, greatly improving inspection efficiency. For special curtain walls that are not suitable for adsorption or magnetic fixing, the fixing ears on the left and right sides of the frame body can be used to fix them by drilling bolts, ensuring that the sealing frame can be stably installed under various complex working conditions. The three fixing methods complement each other, ensuring the reliability of the fixing and allowing for flexible selection according to the curtain wall material and site conditions, significantly enhancing the versatility and applicability of the sealing frame.

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0029] like Figures 1 to 5 As shown, this utility model provides a sealing frame for testing the air tightness of building curtain walls, including a frame body 1, a sealing plate 2 installed on the frame body 1, an airbag sealing assembly 3 installed on the frame body 1, and an adsorption fixing assembly 4 and a magnetic fixing assembly 5 respectively installed on the frame body 1.

[0030] The airbag sealing assembly 3 includes an airbag strip 31 located on the rear side of the frame body 1. Part of the airbag strip 31 is embedded in the frame body 1. The airbag strip 31 is connected to an embedding tube 32. One end of the embedding tube 32 is connected to a pipe joint 33. The pipe joint 33 is connected to an air guide tube 34. The air guide tube 34 is connected to an air pump 35. Before testing, the airbag strip 31 is inflated by the air pump 35. After the airbag strip 31 expands, it can fit tightly against the curtain wall surface. Even if there is some unevenness or installation error on the curtain wall surface, the expanded airbag can adaptively fill the gap. Compared with traditional sealing strips, its sealing effect is better, which can effectively reduce gas leakage during the testing process and improve the accuracy of air tightness test data.

[0031] The adsorption fixing component 4 includes a first fixing plate 41 fixed at the four corners of the frame body 1. The first fixing plate 41 is connected to a first displacement adjustment component 42. The first displacement adjustment component 42 is connected to a suction cup 43. The adsorption fixing component 4 can achieve fast and stable installation without damaging the surface of the glass curtain wall through the negative pressure adsorption force generated by the suction cup 43. It is particularly suitable for glass curtain wall inspection with high requirements for surface integrity.

[0032] The magnetic fixing component 5 includes a second fixing plate 51 fixed at the four corners of the frame body 1. The second fixing plate 51 is connected to a second displacement adjustment component 52, and the second displacement adjustment component 52 is connected to a strong magnetic block 53. The magnetic fixing component 5 can be firmly attached to the metal curtain wall by means of the magnetic force of the strong magnetic block 53. No additional tools are required during the installation process, which greatly improves the inspection efficiency.

[0033] Specifically, a pressure detection connection port 6 is installed on the sealing plate 2 on the front side of the frame body 1, and two pressure detection probes 7 are installed on the inner wall of the frame body 1. The pressure detection connection port 6 is used to connect external detection equipment, introduce pressure signals, and realize the regulation and monitoring of the pressure in the sealed cavity. The two pressure detection probes 7 are installed on the inner wall of the frame to perform multi-point real-time detection, ensure data reliability, and assist in judging the airtightness of the curtain wall.

[0034] Furthermore, the left and right sides of the frame body 1 are fixedly connected with symmetrically arranged fixing ears 8, and fixing holes 9 are opened on the fixing ears 8, which provides an additional mechanical fixing method for the sealed frame. When the adsorption fixing component 4 or the magnetic fixing component 5 is not applicable, the frame can be connected to the curtain wall or the main structure by bolts passing through the fixing holes 9 to ensure the stability of the frame.

[0035] Furthermore, a pressure relief valve 10 is installed on the sealing plate 2 on the right side of the frame body 1. The pressure relief valve 10 is installed on the sealing plate 2 on the right side of the frame body 1. During the airtightness test, if the pressure in the sealed cavity exceeds the safety threshold, the excess pressure can be released quickly and automatically to prevent the excessive pressure from damaging the frame or curtain wall structure. At the same time, after the test, the pressure relief valve 10 can quickly balance the air pressure inside and outside the cavity, making it easy to disassemble the sealed frame safely and conveniently.

[0036] It is worth noting that both the first displacement adjustment component 42 and the second displacement adjustment component 52 are composed of a threaded rod 421, a threaded tube 422, and a connecting bearing 423. The threaded rod 421 is threadedly connected to the threaded tube 422, and the end of the threaded tube 422 is connected to the suction cup 43 or the strong magnetic block 53 respectively through the connecting bearing 423.

[0037] It is worth noting that a locking bolt is installed on the threaded tube 422. The end of the locking bolt abuts against the threaded rod 421. The locking bolt on the threaded tube 422 can fix the threaded rod 421 after the position and pressure of the suction cup 43 or the strong magnetic block 53 are adjusted, so as to prevent it from being displaced due to vibration, pressure changes or other factors during the detection process.

[0038] Among them, the air pump 35 and the air pressure detection probe 7 are existing technologies and will not be described in detail; at the same time, this utility model also includes a power supply, a controller and a switch, etc., which are not the main technical points of this patent and will not be described in detail.

[0039] Working principle and process: When using this building curtain wall airtightness testing sealing frame, first select the fixing method according to the curtain wall material. If it is a glass curtain wall, rotate the threaded tube 422 in the first displacement adjustment component 42, and use its threaded connection with the threaded rod 421 to adjust the position and adsorption force of the suction cup 43. After adjustment, use the locking bolt on the threaded tube 422 to hold the threaded rod 421 in place. If it is a metal curtain wall, rotate the threaded tube in the second displacement adjustment component 52 in the same way to adjust the position and adsorption force of the strong magnet 53, and fix it with the locking bolt. For special cases... Alternatively, the fixing holes 9 of the fixing ears 8 on the left and right sides of the frame body 1 can be used to fix it with bolts. After fixing, the air pump 35 is connected to the air guide pipe 34, and the air bag strip 31 is inflated through the pipe joint 33 and the embedded pipe 32 to form a sealed chamber. Then, the air pressure detection equipment is connected through the air pressure detection connection port 6, and the air pressure in the chamber is monitored by the two air pressure detection probes 7 on the inner wall of the frame body 1. If the pressure in the sealed chamber is too high during the detection process, the pressure can be released through the pressure relief valve 10 on the sealing plate 2 on the right side of the frame body 1 to ensure detection safety and data accuracy.
