Description

Technical Field

[0001] This utility model relates to the field of curtain wall technology, specifically to a weld-free adapter. Background Technology

[0002] In the field of building curtain wall engineering, the connection between the curtain wall and the main structure typically relies on adapters. Traditionally, welding is commonly used to fix the adapters to the main structure. Specifically, during construction, elongated holes are first drilled in the adapters to accommodate installation deviations. After the curtain wall position is adjusted, gaskets or connectors are welded between the adapters and the main structure to ensure the stability of the curtain wall system. However, this welding-dependent connection method has many drawbacks and fails to meet the stringent requirements of modern architecture for safety, health, environmental protection, and construction efficiency.

[0003] First, the welding process itself presents significant safety and health risks. The arc light, high-temperature spatter, and harmful gases (such as carbon monoxide, ozone, and nitrogen oxides) generated during welding directly threaten the health of construction workers, and long-term exposure may lead to occupational respiratory diseases or skin damage. In addition, high-temperature welding is prone to causing fires, especially when working in high-rise buildings or confined spaces, where the risks are further amplified.

[0004] Secondly, welding technology runs counter to the concept of green construction. Welding consumes a large amount of electricity, has high carbon emissions, and the welding fumes contain heavy metal particles and toxic compounds, causing pollution to the construction site and the surrounding environment.

[0005] Furthermore, welded structures are difficult to adjust or maintain flexibly. During curtain wall installation, due to errors in the main structure or environmental factors, the position of the transition pieces often needs to be fine-tuned multiple times. However, the welded connection is rigidly fixed, and disassembly requires cutting or damaging the weld, which is not only time-consuming and labor-intensive but also reduces the overall strength of the structure and increases later maintenance costs.

[0006] Therefore, this application provides a solderless adapter system to solve the above-mentioned problems. Utility Model Content

[0007] In view of this, the present invention provides a weld-free adapter to solve the problem that curtain walls and main structures are usually fixed by welding.

[0008] This utility model provides a solderless adapter, comprising:

[0009] The adapter includes a first adapter segment and a second adapter segment, wherein the first adapter segment and the second adapter segment are perpendicular to each other at the connection point; both the first adapter segment and the second adapter segment are provided with elongated holes;

[0010] A gasket having a first through hole and at least two first fixing holes, wherein a second fastener is inserted into the two first fixing holes of the gasket, the gasket being configured to be fixed by the second fastener to the surface of the first adapter section of the adapter, and the first through hole communicating with the elongated hole of the first adapter section;

[0011] The first fastener has one end inserted sequentially into the first through hole of the gasket and the elongated hole of the first adapter section, and the other end of the first fastener abuts against the outer surface of the gasket; and the first fastener is configured to be fixed to the main structure after being inserted into the elongated hole.

[0012] A first toothed washer has a second through hole and at least two second fixing holes. The two second fixing holes of the first toothed washer are adapted to insert a fourth fastener. The first toothed washer is configured to be fixed to the surface of the second transition section of the adapter by the fourth fastener.

[0013] The second toothed gasket has a third through hole and is adapted to the first toothed gasket.

[0014] The third fastener has one end inserted sequentially into the third through hole of the second toothed washer, the second through hole of the first toothed washer, and the elongated hole of the second transition section. The other end of the third fastener abuts against the outer surface of the second toothed washer, and the end of the third fastener inserted into the elongated hole of the second transition section is configured to be fixed to the main keel of the curtain wall.

[0015] The second through hole of the first toothed gasket is an oblong hole, which is aligned with the oblong hole of the second transition section.

[0016] In terms of installation, the operation process is relatively simple, requiring no complex welding procedures, which greatly shortens construction time and improves installation efficiency. From a maintenance perspective, due to the use of mechanical connections, subsequent maintenance can be performed non-destructively by removing the corresponding fasteners, facilitating the inspection and replacement of components on the curtain wall or transition device, effectively reducing maintenance costs. Regarding safety and health, it avoids open-fire welding, eliminating the threats to the health of construction workers caused by arc light, high-temperature spatter, and harmful gases generated during welding, while also reducing the risk of fire. Moreover, this device aligns with green environmental protection principles, reducing energy consumption and carbon emissions during the welding process.

[0017] In one alternative embodiment, the elongated holes on the first transition section and the second transition section are both formed along their respective width directions.

[0018] During installation, the elongated holes along the width provide more flexible adjustment space for the connection between the adapter and the main structure and the main curtain wall keel. Taking the connection between the adapter and the main structure as an example, if there is a certain dimensional deviation in the main structure or a slight error in the installation position, the position of the first fastener within the elongated hole can be finely adjusted in the width direction because the elongated hole is set along the width direction of the first adapter section. This allows the adapter to better fit the main structure. Similarly, similar adjustments can be made when connecting the adapter to the main curtain wall keel. After fine-tuning, the shims, toothed shims, and other components are fixed with appropriate fasteners to ensure the stability of the connection. This method of setting elongated holes further enhances the practicality of the device. It improves the installation accuracy and adaptability, better addresses minor differences in size and position between the main structure and the main curtain wall keel, and ensures the quality of curtain wall installation.

[0019] In one optional implementation, the number of the third fasteners is two, and the number of the second toothed washers is two;

[0020] The two third fasteners are spaced apart.

[0021] In one optional embodiment, both the first toothed pad and the second toothed pad have strip-shaped grooves on their adjacent sides, and the strip-shaped grooves on the first toothed pad and the second toothed pad engage with each other.

[0022] In one alternative implementation, one adapter is fixed to each side of the main structure.

[0023] In one alternative implementation, both the first fastener and the third fastener are anchor bolts.

[0024] In one alternative embodiment, both the second fastener and the fourth fastener are screws.

[0025] In one optional embodiment, both the first fixing hole and the second fixing hole are screw holes. Attached Figure Description

[0035] In the field of building curtain wall engineering, the connection between the curtain wall and the main structure 7 usually relies on the adapter 1. In traditional technology, the adapter 1 and the main structure 7 are generally fixed by welding. Specifically, during construction, an elongated hole needs to be drilled in the adapter 1 to accommodate installation deviations. After the curtain wall position is adjusted, the gasket 2 or connector is fixed between the adapter 1 and the main structure 7 by welding, thereby ensuring the stability of the curtain wall system. However, this welding-dependent connection method has many drawbacks and is difficult to meet the stringent requirements of modern buildings for safety, health, environmental protection, and construction efficiency.

[0036] First, the welding process itself presents significant safety and health risks. The arc light, high-temperature spatter, and harmful gases (such as carbon monoxide, ozone, and nitrogen oxides) generated during welding directly threaten the health of construction workers, and long-term exposure may lead to occupational respiratory diseases or skin damage. In addition, high-temperature welding is prone to causing fires, especially when working in high-rise buildings or confined spaces, where the risks are further amplified.

[0037] Secondly, welding technology runs counter to the concept of green construction. Welding consumes a large amount of electricity, has high carbon emissions, and the welding fumes contain heavy metal particles and toxic compounds, causing pollution to the construction site and the surrounding environment.

[0038] Furthermore, the welded structure is difficult to adjust or maintain flexibly. During curtain wall installation, due to errors in the main structure or environmental factors, the position of the adapter 1 often needs to be finely adjusted multiple times. However, the welded connection is rigidly fixed, and disassembly requires cutting or damaging the weld, which is not only time-consuming and labor-intensive but also reduces the overall strength of the structure and increases later maintenance costs. Therefore, this embodiment provides a weld-free adapter system to solve the above problems.

[0039] The following is combined with Figures 1 to 5 The following describes embodiments of the present invention.

[0040] According to an embodiment of the present invention, a solderless adapter is provided, including an adapter 1, a gasket 2, a first fastener 3, a first toothed gasket 4, a second toothed gasket 5, and a third fastener 6. The adapter 1 includes a first adapter segment 101 and a second adapter segment 102, which are perpendicular to each other at the connection point. Both the first adapter segment 101 and the second adapter segment 102 have elongated holes. The gasket 2 has a first through hole and at least two first fixing holes. Second fasteners 9 are inserted into the two first fixing holes of the gasket 2. The gasket 2 is configured to be fixed to the surface of the first adapter segment 101 of the adapter 1 by the second fasteners 9, and the first through hole communicates with the elongated hole of the first adapter segment 101. One end of the first fastener 3 is sequentially inserted into the first through hole of the gasket 2 and the elongated hole of the first adapter segment 101, and the other end of the first fastener 3 abuts against the outer surface of the gasket 2. The first fastener 3 is configured to be inserted into the elongated hole. The first toothed gasket 4 is provided with a second through hole and at least two second fixing holes. The two second fixing holes of the first toothed gasket 4 are suitable for inserting a fourth fastener 10. The first toothed gasket 4 is configured to be fixed to the surface of the second transition section 102 of the adapter 1 by the fourth fastener 10. The second toothed gasket 5 is provided with a third through hole. The second toothed gasket 5 is adapted to the first toothed gasket 4. One end of the third fastener 6 is sequentially inserted into the third through hole of the second toothed gasket 5, the second through hole of the first toothed gasket 4 and the elongated hole of the second transition section 102. The other end of the third fastener 6 abuts against the outer surface of the second toothed gasket 5. The end of the third fastener 6 inserted into the elongated hole of the second transition section 102 is configured to be fixed to the main keel 8 of the curtain wall.

[0041] The second through hole of the first toothed gasket 4 is an oblong hole, which is aligned with the oblong hole of the second adapter section 102.

[0042] In the installation and construction of building curtain walls, the working process of this weld-free adapter is as follows: First, the adapter 1 is connected to the main structure 7. The gasket 2 is fixed to the surface of the first adapter section 101 of the adapter 1 using the second fastener 9, ensuring that the first through hole on the gasket 2 communicates with the elongated hole of the first adapter section 101. Next, one end of the first fastener 3 is passed through the first through hole of the gasket 2 and the elongated hole of the first adapter section 101 in sequence, so that the other end of the first fastener 3 abuts against the outer surface of the gasket 2. Then, the end of the first fastener 3 inserted into the elongated hole is fixed to the main structure 7, thus the first adapter section 101 of the adapter 1 is firmly connected to the main structure 7.

[0043] Next, the main curtain wall keel 8 and the adapter 1 are connected. The first toothed washer 4 is fixed to the surface of the second adapter section 102 of the adapter 1 using the fourth fastener 10, and then the matching second toothed washer 5 is placed. Then, one end of the third fastener 6 is inserted sequentially into the third through hole of the second toothed washer 5, the second through hole of the first toothed washer 4, and the elongated hole of the second adapter section 102, so that the other end of the third fastener 6 abuts against the outer surface of the second toothed washer 5. Finally, the end of the third fastener 6 inserted into the elongated hole of the second adapter section 102 is fixed to the main curtain wall keel 8, thus completing the installation of the entire weld-free adapter device.

[0044] This weld-free adapter has demonstrated significant effectiveness in practical applications. In terms of installation, its operation is relatively simple, eliminating the need for complex welding procedures, greatly shortening construction time and improving installation efficiency. From a maintenance perspective, due to the mechanical connection method, subsequent maintenance can be performed non-destructively by removing the corresponding fasteners, facilitating inspection and replacement of components on the curtain wall or adapter, effectively reducing maintenance costs. Regarding safety and health, it avoids open-fire welding, eliminating the threats to the health of construction workers caused by arc light, high-temperature spatter, and harmful gases generated during welding, while also reducing the risk of fire. Furthermore, this device aligns with green environmental protection principles, reducing energy consumption and carbon emissions during the welding process.

[0045] In one embodiment, the elongated holes on the first transition section 101 and the second transition section 102 are both opened along their respective width directions.

[0046] During installation, the elongated holes along the width direction provide more flexible adjustment space for the connection between the adapter 1 and the main structure 7 and the main curtain wall keel 8. Taking the connection between the adapter 1 and the main structure 7 as an example, if there is a certain dimensional deviation or slight error in the installation position of the main structure 7, the position of the first fastener 3 within the elongated hole can be finely adjusted in the width direction because the elongated hole is set along the width direction of the first adapter section 101, so that the adapter 1 can better fit the main structure 7. Similarly, similar adjustments can be made when connecting the adapter 1 and the main curtain wall keel 8. After fine-tuning, the corresponding fasteners are used to fix the shims 2, toothed shims 2, and other components to ensure the stability of the connection. This method of setting elongated holes further enhances the practicality of the device. It improves the installation accuracy and adaptability, and can better cope with minor differences in size and position between the main structure 7 and the main curtain wall keel 8, ensuring the quality of curtain wall installation.

[0047] In one embodiment, such as Figure 3 As shown, there are two third fasteners 6 and two second toothed washers 5; the two third fasteners 6 are spaced apart.

[0048] The two spaced third fasteners 6 and two second toothed washers 5, compared with a single fastener and toothed washers 2, can more evenly distribute the load transmitted by the main curtain wall keel 8, effectively reduce the risk of excessive local stress on the adapter 1, make the connection between the adapter 1 and the main curtain wall keel 8 more stable and reliable, improve the safety and stability of the entire curtain wall system, and reduce safety hazards caused by loose connections.

[0049] In one embodiment, the first toothed gasket 4 and the second toothed gasket 5 are provided with strip-shaped grooves on their adjacent sides, and the strip-shaped grooves on the first toothed gasket 4 and the second toothed gasket 5 are engaged with each other.

[0050] The toothed gasket 4 and the second toothed gasket 5 interlock with each other, greatly enhancing their friction and engagement force. When subjected to external forces such as vibration or wind, the two toothed gaskets 2 are unlikely to rotate relative to each other, effectively preventing the third fastener 6 from loosening. This ensures a stable and reliable connection between the adapter 1 and the main curtain wall keel 8, improving the safety and stability of the entire curtain wall system and reducing the risk of safety accidents caused by loose connections.

[0051] In one embodiment, such as Figure 4 As shown, a connector 1 is fixed on each side of the main structure 7.

[0052] In one embodiment, both the first fastener 3 and the third fastener 6 are anchor bolts.

[0053] In one embodiment, both the second fastener 9 and the fourth fastener 10 are screws. Both the first fixing hole and the second fixing hole are screw holes.

[0054] Although embodiments of the present invention have been described in conjunction with the accompanying drawings, those skilled in the art can make various modifications and variations without departing from the spirit and scope of the present invention, and such modifications and variations all fall within the scope defined by the appended claims.
