Description

Technical Field

[0001] This invention relates to the field of weld-free post-installed embedded parts technology, specifically a prefabricated aluminum alloy weld-free post-installed embedded part for building curtain walls. Background Technology

[0002] Building curtain walls are commonly used external envelope structures for modern large and high-rise buildings. They consist of panels and a supporting structural system. Traditional curtain wall installation often relies on embedded parts to connect with the main structure. However, in actual projects, due to objective factors such as design changes, embedded part misalignment, or renovation of existing buildings, embedded parts often cannot meet the installation requirements. Therefore, post-installed embedded parts are needed as a remedial or alternative connection solution. Post-installed embedded parts refer to anchoring components that fix connecting members to the base material after the main structure concrete has been formed, using anchor bolts. Typical post-installed embedded parts include anchor plates, anchor bolts, and transition brackets. The anchor plates are connected to the concrete structure via anchor bolts, and the brackets are then connected to the curtain wall keel, forming a complete force transmission path. In building curtain wall engineering, post-installed embedded parts provide a flexible and adjustable fixed foundation for the curtain wall system. They are the core components connecting the curtain wall frame and the main structure and are widely used in scenarios such as missed or incorrect embedding of pre-embedded parts and curtain wall renovation. Traditional post-installed embedded components mostly adopt steel welded structures, requiring on-site welding of steel angle brackets to steel embedded plates. In actual construction, this necessitates on-site welding by professional welders, a cumbersome process requiring not only pre-welding preparation but also demanding environmental conditions. Therefore, we propose a prefabricated, weld-free aluminum alloy post-installed embedded component for building curtain walls. Summary of the Invention

[0006] Preferably, the anchor plate has a plurality of waist-shaped positioning holes, and the inner wall of the positioning holes has a limiting groove A and a limiting groove B respectively.

[0009] Preferably, a limiting strip B is fixedly connected to the positioning seat B, the limiting strip B is located in the limiting groove B, the limiting strip B and the limiting groove B are slidably connected, and two mounting grooves are opened on the side of the positioning seat B near the positioning seat A, and the two mounting grooves are respectively aligned with the mounting holes on the same side.

[0010] Preferably, a mounting plate is fixedly connected inside the fitting groove, a sleeve is fixedly connected to the mounting plate, the sleeve is located inside the mounting hole, a mounting rod is slidably connected inside the sleeve, the mounting rod is located inside the mounting groove, the end of the mounting rod away from the sleeve is fixedly connected to the inner wall of the mounting groove, and a mounting spring is fixedly connected between the mounting rod and the inner wall of the sleeve.

[0011] Preferably, wear-resistant lining plates are fixedly connected to the opposite sides of the two corner brackets, and guide grooves are provided at the top and bottom of the corner brackets. The upper rail and the lower rail are fitted into the guide grooves on the same side, and the upper rail and the lower rail are slidably connected to the guide grooves on the same side.

[0012] Preferably, the positioning seat A and positioning seat B are provided with threaded holes that are aligned with each other, the threaded holes are located between the two mounting holes, and mounting bolts are threaded into the threaded holes.

[0013] Preferably, each of the corner brackets and wear-resistant liners has a waist-shaped connection hole, and each of the connection holes is aligned with each other. The corner brackets and anchor plates are threadedly connected by fastening bolts.

[0014] Compared with the prior art, the beneficial effects of the present invention are: 1. This invention transforms the traditional on-site welding method of post-installed embedded parts into a prefabricated construction mode of factory prefabrication and on-site bolt assembly by using anchor plates, upper rails, lower rails and corner brackets made of all-aluminum alloy materials. The anchor plate has waist-shaped positioning holes. During construction, the holes are first drilled and cleaned, and the anchor plate is fixed to the main structure with chemical anchors. Then, the corner brackets are slid into the rail slots and adjusted horizontally to the required position. The curtain wall steel keel and the corner brackets are connected and fixed with hexagonal bolts. Finally, stainless steel self-tapping screws are used to lock the corner brackets to the anchor plate to prevent slippage. The entire construction process does not require on-site welding, which effectively solves the problems of time-consuming and labor-intensive traditional welding processes, easy corrosion and fire hazards, and significantly improves installation efficiency and connection reliability. 2. This invention features a corrugated surface A on the inner top wall of the upper track and a corrugated surface B on the inner bottom wall of the lower track, with their slopes, troughs, and crests staggered. Combined with a guide rod held in place by a fixed spring within the corner code storage slot, the corner code can self-lock at any position during horizontal movement due to the friction between the guide rod and the corrugated surface, preventing it from sliding due to gravity or external force. Simultaneously, a chip removal port at the trough of corrugated surface B allows dust and debris falling into the track to be promptly discharged, preventing impurities from getting stuck between the guide rod and the corrugated surface, ensuring smooth sliding. This avoids the shortcomings of traditional sliding adjustment mechanisms that require additional locking devices or cannot be positioned at arbitrary locations, achieving stepless adjustment and instant self-locking of the corner code in the horizontal direction. 3. This invention uses sliding positioning seats A and B within the positioning holes of the waist-shaped structure of the anchor plate. The threaded holes on both seats guide the mounting bolts, ensuring they remain perpendicular to the structure when driven into the pre-drilled holes. This guarantees the verticality and reliability of the anchoring connection. Simultaneously, positioning seats A and B can slide synchronously along the positioning holes of the waist-shaped structure, facilitating flexible adjustment based on the actual position of the pre-drilled holes on the structure. After the mounting bolts are tightened, the compressed mounting spring continuously applies a reverse thrust to positioning seat A, creating a counterbalance with the bolt tightening pressure. This effectively prevents bolt loosening caused by minor vibrations over time, achieving precise adjustment of the anchoring position and long-term anti-loosening. Attached Figure Description

[0017] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0018] Please see Figure 1-8 This invention provides a technical solution: a prefabricated aluminum alloy weld-free post-installed embedded part for building curtain walls, including an anchor plate 1. An upper rail 2 and a lower rail 22 are fixedly connected to one side of the anchor plate 1. Two corner brackets 3 are slidably connected between the upper rail 2 and the lower rail 22. Wear-resistant lining plates 31 are fixedly connected to the opposite sides of the two corner brackets 3. Guide grooves 33 are provided at the top and bottom of the corner brackets 3. The upper rail 2 and the lower rail 22 are fitted into the guide grooves 33 on the same side. The upper rail 2 and the lower rail 22 are slidably connected to the guide grooves 33 on the same side. Each corner bracket 3 and the wear-resistant lining plate 31 are provided with waist-shaped connecting holes 32. Each connecting hole 32 is aligned with each other. Fastening bolts 35 are threadedly connected between the corner brackets 3 and the anchor plate 1.

[0019] Furthermore, during the installation of the building curtain wall, the anchor plate 1 is first fixed to the structure. Then, the two corner brackets 3 are placed between the upper track 2 and the lower track 22, and the horizontal position between the two corner brackets 3 is adjusted so that the two corner brackets 3 are attached to both sides of the curtain wall steel keel. Then, the corner brackets 3 are installed and fixed to the anchor plate 1 using fastening bolts 35. Finally, the two corner brackets 3 are connected and fixed to the curtain wall steel keel using hexagonal bolts.

[0020] Combined with appendix Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 7 As shown, the inner top wall of the upper track 2 is provided with a corrugated surface A21, and the inner bottom wall of the lower track 22 is provided with a corrugated surface B23. Both corrugated surfaces A21 and B23 are composed of slopes, troughs and crests. The slopes, troughs and crests of corrugated surfaces A21 and B23 are staggered. A chip discharge port 24 penetrating the lower track 22 is opened on the trough of corrugated surface B23. A positioning groove 25 is opened on the top of the crest of corrugated surface B23. The top and bottom of the corner bracket 3 near the anchor plate 1 are provided with a receiving groove 34. A guide rod 4 is slidably connected in the receiving groove 34. A fixing spring 41 is fixedly connected between the guide rod 4 and the inner wall of the receiving groove 34 on the same side. One end of the guide rod 4 in the two receiving grooves 34 contacts the corrugated surface A21 and corrugated surface B23 on the same side, respectively. The end of the guide rod 4 is a hemispherical structure.

[0021] Furthermore, during the adjustment of the horizontal position of the corner bracket 3, a guide rod 4 is provided in the storage groove 34 at the top of the corner bracket 3. Under the elastic force of the fixing spring 41, the guide rod 4 is always pressed against the corrugated surface A21 of the upper track 2. Another guide rod 4 is provided in the storage groove 34 at the bottom of the corner bracket 3. Under the elastic force of the fixing spring 41, the guide rod 4 is always pressed against the corrugated surface B23 of the lower track 22. Due to the misaligned distribution of the slopes, troughs, and crests of the corrugated surfaces A21 and B23, the two guide rods 4 are always... At different phase positions, when the guide rod 4 at the bottom of the corner code 3 moves to the crest of the corrugated surface B23, the end of the guide rod 4 is slightly embedded in the positioning groove 25 opened at the top of the crest. At the same time, the guide rod 4 at the top of the corner code 3 moves to the trough of the corrugated surface A21. When the guide rod 4 at the bottom of the corner code 3 moves to the trough of the corrugated surface B23, the end of the guide rod 4 is slightly embedded in the edge of the chip discharge port 24 opened at the trough. At the same time, the guide rod 4 at the top of the corner code 3 moves to the trough of the corrugated surface A21. At the crest of A21, because the diameters of the positioning groove 25 and the chip discharge port 24 are slightly smaller than the diameter of the guide rod 4, the hemispherical end of the guide rod 4 can form a micro-fit with the edges of the positioning groove 25 and the chip discharge port 24 through its arc surface. This not only avoids the guide rod 4 from being completely inserted into the positioning groove 25 and the chip discharge port 24 and getting stuck, but also provides additional tangential resistance at the critical point, effectively preventing the corner bracket 3 from unstable slippage due to sudden changes in force state when the guide rod 4 passes through the crest or trough. This works in conjunction with the corrugated surface A21 and the corrugated surface B2. The staggered distribution of the three guide rods 4 ensures that the two guide rods 4 are always in a complementary state of being high and low, so that the corner bracket 3 can remain stable after being released at any position and will not slide on its own due to gravity or external force. At the same time, the groove structure of the lower track 22 is prone to accumulating dust and debris during installation. After these impurities fall on the corrugated surface B23, they will slide down the slope to the chip discharge port 24 at the trough and be discharged from the track from the chip discharge port 24. This effectively avoids impurities getting stuck between the guide rod 4 and the corrugated surface B23, ensuring smooth sliding.

[0022] Combined with appendix Figure 1 , Figure 4 , Figure 5 , Figure 6 and Figure 7As shown, the anchor plate 1 has several waist-shaped positioning holes 11. The inner walls of the positioning holes 11 are respectively provided with limiting grooves A12 and B13. The width of limiting groove A12 is greater than the width of limiting groove B13. The anchor plate 1 has several sets of scale grooves 14, each set of scale grooves 14 located on one side of a corresponding positioning hole 11. Positioning seats A5 and B6 are slidably connected within the positioning holes 11. A limiting strip A53 is fixedly connected to the positioning seat A5, which is located within the limiting groove A12. The limiting strip A53 and the limiting groove A12 are slidably connected. A rubber strip 54 is fixedly connected to the side of the limiting strip A53 closest to the positioning seat B6. Two fitting grooves 52 are provided on the side of the positioning seat A5 away from the positioning seat B6. Each fitting groove 52 has an installation hole 51. A limiting strip 54 is fixedly connected to the positioning seat B6. A limiting strip B62 is located within a limiting groove B13 and is slidably connected to the limiting groove B13. Two mounting grooves 61 are provided on the side of the positioning seat B6 near the positioning seat A5, and these two mounting grooves 61 are aligned with mounting holes 51 on the same side. A mounting plate 73 is fixedly connected within a fitting groove 52, and a sleeve 7 is fixedly connected to the mounting plate 73. The sleeve 7 is located within the mounting hole 51, and a mounting rod 71 is slidably connected within the sleeve 7. The mounting rod 71 is located within the mounting groove 61, and the end of the mounting rod 71 furthest from the sleeve 7 is fixedly connected to the inner wall of the mounting groove 61. A mounting spring 72 is fixedly connected between the mounting rod 71 and the inner wall of the sleeve 7. Aligned threaded holes 8 are provided on both the positioning seat A5 and the positioning seat B6, and the threaded holes 8 are located between the two mounting holes 51. Mounting bolts 81 are threadedly connected to the threaded holes 8.

[0023] Furthermore, when fixing the anchor plate 1 to the structure, holes are first pre-drilled in the structure. Then, the anchor plate 1 is attached to the surface of the structure, and the positioning seat A5 is manually moved along the positioning hole 11 to align the threaded hole 8 with the pre-drilled hole on the structure. During the adjustment process, the positioning seat A5 drives the positioning seat B6 to move synchronously through the cooperation of the sleeve 7 and the mounting rod 71. After alignment, the mounting bolt 81 is screwed into the threaded hole 8. Using the guiding effect of the threaded hole 8, the mounting bolt 81 is kept perpendicular to the structure and driven into the pre-drilled hole. When tightening the mounting bolt 81, the bolt head applies a thrust to the positioning seat A5, pushing the positioning seat A5 to move towards the positioning seat B6. At this time, the positioning seat A5 drives the limiting strip A53 and the rubber strip 54 to move synchronously. Until the rubber strip 54 adheres to the inner wall of the limiting groove A12, the pressure provided by the mounting bolt 81 and the friction generated by the rubber strip 54 work together to lock the positioning seats A5 and B6 in their current positions within the positioning hole 11. This prevents the tightness of the mounting bolt 81 from being affected by minor vibrations caused by external forces over a long period of time. As the positioning seat A5 moves toward the positioning seat B6, the sleeve 7 and the mounting rod 71 contract relative to each other, simultaneously compressing the mounting spring 72. After the mounting bolt 81 is fixed, the mounting spring 72 continuously applies a counter-force to the positioning seat A5 in the opposite direction to the bolt thrust. The two counter-forces balance each other, which is equivalent to applying a continuous pre-tightening holding force to the threaded connection, thereby further improving the anti-loosening stability of the mounting bolt 81.

[0024] Working principle: First, pre-drill reserved holes on the main building structure and determine the fixing position of anchor plate 1. Use tools such as electric hammer to drill pre-drilled holes on the concrete structure that match the installation bolts 81, and clean the dust in the holes. Then, the anchor plate 1 is attached to the surface of the structure, so that the positioning hole 11 on the anchor plate 1 is roughly aligned with the pre-drilled hole area. Then, the positioning seat A5 is manually moved along the positioning hole 11. At the same time, the scale groove 14 on the anchor plate 1 is observed to precisely adjust the position of the positioning seat A5 so that the threaded hole 8 on the positioning seat A5 and the positioning seat B6 are completely aligned with the pre-drilled hole on the structure. During the adjustment of the positioning seat A5, the positioning seat A5 drives the positioning seat B6 to move synchronously through the cooperation of the sleeve 7 and the mounting rod 71 to ensure that the two positioning seats always remain aligned. Next, the mounting bolt 81 is passed through the threaded hole 8. Using the guiding effect of the threaded hole 8, the mounting bolt 81 is kept perpendicular to the surface of the structure. It is then smoothly driven into the pre-drilled hole on the structure. The mounting bolt 81 is then tightened to lock the positioning seats A5 and B6. A wrench is used to tighten the mounting bolt 81, and the bolt head applies a pushing force to the positioning seat A5, pushing it towards the positioning seat B6. At this time, the positioning seat A5 drives the limiting strip A53 and the rubber strip 54 to move synchronously until the rubber strip 54 fits into the inner part of the limiting groove A12. The pressure provided by the mounting bolt 81 and the friction generated by the rubber strip 54 work together to lock the positioning seat A5 and positioning seat B6 in their current positions within the positioning hole 11. At the same time, as the positioning seat A5 moves toward the positioning seat B6, the sleeve 7 and the mounting rod 71 retract relative to each other and compress the mounting spring 72. After the mounting bolt 81 is fixed, the mounting spring 72 continuously applies a counter-force to the positioning seat A5 in the opposite direction to the bolt thrust. The two counter-forces balance each other, effectively preventing the mounting bolt 81 from loosening due to long-term minor vibrations. Then, place the two corner brackets 3 between the upper track 2 and the lower track 22 respectively, so that the guide groove 33 at the top of the corner bracket 3 is engaged with the upper track 2, and the guide groove 33 at the bottom of the corner bracket 3 is engaged with the lower track 22. At this time, the two corner brackets 3 can slide horizontally along the track direction. Meanwhile, the guide rod 4 in the storage groove 34 at the top of the corner bracket 3 is always pressed against the corrugated surface A21 of the upper track 2 under the elastic force of the fixed spring 41, and the guide rod 4 in the storage groove 34 at the bottom of the corner bracket 3 is always pressed against the corrugated surface B23 of the lower track 22 under the elastic force of the fixed spring 41. At this point, based on the position of the curtain wall steel keel, the corner bracket 3 is pushed to slide along the upper track 2 and the lower track 22, so that the two corner brackets 3 are respectively in contact with the two sides of the steel keel. During the sliding process, due to the misaligned distribution of the slopes, troughs and crests of the corrugated surfaces A21 and B23, the two guide rods 4 are always in different phase positions. When the guide rod 4 at the bottom of the corner bracket 3 moves to the crest of the corrugated surface B23, the hemispherical end of the guide rod 4 is slightly embedded in the positioning groove 25 at the top of the crest. At this time, the guide rod 4 at the top of the corner bracket 3 is exactly located at the trough of the corrugated surface A21; when the guide rod 4 at the bottom of the corner bracket 3 moves to the trough of the corrugated surface B23... At this time, the end of the guide rod 4 is slightly embedded in the edge of the chip discharge port 24 at the trough. At this time, the guide rod 4 at the top of the corner code 3 is exactly located at the crest of the corrugated surface A21. This micro-embedding effect not only avoids the guide rod 4 from being completely inserted into the positioning groove 25 or the chip discharge port 24 and getting stuck, but also provides additional tangential resistance at the critical point between the crest and the trough, preventing the corner code 3 from unstable slippage due to the sudden change in force state when the guide rod 4 passes through the crest or trough. At the same time, the dust and debris accumulated in the groove structure of the lower track 22 will slide down the slope of the corrugated surface B23 to the chip discharge port 24 at the trough and be discharged from the chip discharge port 24 to the outside of the track, ensuring smooth sliding. After the two corner brackets 3 are adjusted to the required positions, use the fastening bolts 35 to lock the corner brackets 3 to the anchor plate 1. Then, use hex bolts to pass through the connection holes 32 on the wear-resistant liner 31 and the corner brackets 3 in sequence to connect and fix the wear-resistant liner 31 together with the corner brackets 3 to the curtain wall steel keel. The connection hole 32 has a waist-shaped structure, which can finely adjust the alignment of the keel. The wear-resistant liner 31 is attached to the surface of the steel keel, which plays a role in wear resistance and buffering. At this time, the installation of the entire post-embedded part is completed.
