Description
Technical Field
[0001] This invention relates to the field of curtain wall installation auxiliary equipment technology, and in particular to a pre-embedded component for building curtain walls and a construction method thereof. Background Technology
[0002] Building curtain walls refer to the non-load-bearing exterior wall cladding of a building, typically consisting of panels and a supporting structure behind them. The supporting structure is usually connected to the building's exterior wall using embedded curtain wall components. These embedded components are metal parts installed in the supporting structure to increase the stability and safety of the curtain wall. Embedded components are divided into steel plate embedded components and expansion bolt embedded components. The main types of embedded curtain wall components include anchors, supports, expansion joints, and lightning protection components.
[0003] The quality of embedded parts and installation of curtain walls have a significant impact on the safety and service life of curtain walls. When installing existing building curtain walls using embedded parts, it is necessary to manually fasten the building curtain wall to the embedded parts, which is troublesome and cannot meet the automatic locking and limiting of the building curtain wall. Furthermore, it is not convenient to adjust the installation of embedded parts according to the size of the building curtain wall. Summary of the Invention
[0004] To solve the above technical problems, a pre-embedded component for building curtain wall and a construction method are provided.
[0005] The technical solution of the present invention is achieved through the following scheme: a pre-embedded component for a building curtain wall, comprising a building exterior wall, a building curtain wall, and a plurality of channel-shaped positioning bodies. The building exterior wall abuts against the channel-shaped positioning bodies through pre-embedded connecting rods. Two pairs of channel-shaped positioning bodies are connected by a synchronous connection mechanism. The exposed end of the pre-embedded connecting rod passes through an axial anti-deviation seat and is connected to a locking nut. The locking nut can rotate from the exposed end of the pre-embedded connecting rod, so that the pre-embedded end of the pre-embedded connecting rod is fixed inside the building exterior wall. An automatic limiting unit is provided at the exposed end of the pre-embedded connecting rod. The building curtain wall is fixedly installed on the building exterior wall through the channel-shaped positioning bodies and the automatic limiting unit.
[0006] Through the above technical solutions, the automatic limiting unit at the exposed end of the pre-embedded connecting rod automatically locks and limits the building curtain wall, simplifying the installation process. The synchronous connection mechanism precisely adjusts the installation spacing of multiple slotted positioning bodies, enabling the installation of building curtain walls of different sizes. The axial anti-deviation seat effectively prevents radial displacement of the pre-embedded connecting rod during installation and use. The locking nut, in conjunction with the axial anti-deviation seat, ensures the stability of the connection between the pre-embedded connecting rod and the building exterior wall, improving the overall stability and safety of the curtain wall.
[0007] Preferably, the pre-embedded connecting rod includes a snap-fit rod and a limiting sleeve. The limiting sleeve is inserted into the exterior wall of the building, and the exposed end of the limiting sleeve is connected to the axial anti-deviation seat. The snap-fit rod passes through the axial anti-deviation seat and can be slidably installed in the limiting sleeve. The limiting sleeve is fixedly installed in the exterior wall of the building by the snap-fit rod.
[0008] Preferably, the outer surface of the limiting sleeve is provided with a plurality of guide grooves in a circular array. The snap-fit rod includes a central pull rod, a threaded rod, and a limiting rod. One end of the central pull rod is fixedly installed with a threaded rod, and the other end of the central pull rod is provided with a limiting rod. The other end of the limiting rod is rotatably provided with a limiting ring. The limiting ring is adapted to slide and connect inside the limiting sleeve. The outer surface of the limiting rod is provided with a plurality of top rings and a first swing bar group. The ends of the plurality of top rings and the plurality of first swing bar groups all face the limiting ring and are all linearly arranged along the axis of the limiting rod. The first swing bar group passes through the guide groove and is fixedly connected to the building exterior wall. The other end of the threaded rod is provided with a limiting unit groove. The top rings, the first swing bar group, and the limiting rod are umbrella-shaped.
[0009] Preferably, the automatic limiting unit is movably installed in the limiting unit slot. The automatic limiting unit includes a mounting slide, a support spring, a baffle, and a second swing bar. The baffle is fixedly installed in the limiting unit slot, and the mounting slide is slidably installed in the limiting unit slot. The mounting slide is connected to the baffle through the support spring. The bottom end of the second swing bar is rotatably connected to the mounting slide through a pin. The second swing bar is in an inclined state toward the slotted positioning body. The building curtain wall is sleeved on the end of the threaded rod and abuts against the second swing bar.
[0010] Preferably, the grooved positioning body includes a mounting groove plate, a positioning plate, and a hollow toothed plate. An elastic damping pad is snapped onto the outer side of the mounting groove plate near the building's exterior wall. Two hollow toothed plates are fixedly installed on the inner side of the mounting groove plate near the building's exterior wall. A positioning plate is fixedly installed on the top surface of the mounting groove plate. Several positioning teeth protrude from the positioning plate. A waist-shaped mounting hole is provided in the middle of the mounting groove plate between the elastic damping pad and the hollow toothed plate. The two hollow toothed plates are symmetrically installed on both sides of the waist-shaped mounting hole.
[0011] Preferably, the axial anti-deviation seat includes a limiting sleeve, a connecting seat, and a limiting pressure seat. The exposed section of the limiting sleeve passes through the waist-shaped mounting hole and is fitted with the limiting sleeve. The square section of the limiting sleeve is embedded in the connecting seat. The connecting seat is provided with symmetrically arranged ear plates. The connecting seat is inserted into the hollow toothed plate through the ear plates. The ear plates are detachably mounted with positioning teeth blocks by a locking knob. The positioning teeth blocks mesh with the hollow toothed plate. The limiting pressure seat is slidably mounted in the mounting groove plate and abuts against the side of the mounting groove plate away from the building's exterior wall. The limiting pressure seat is sleeved on the ends of the limiting sleeve and the limiting sleeve. A locking nut is rotatably mounted on the limiting pressure seat.
[0012] Preferably, the snap-fit rod, the limiting sleeve, and the axial anti-deviation seat are coaxially arranged, and the threaded rod passes through the limiting pressure seat and is connected to the locking nut.
[0013] The specific steps of the construction method for the embedded parts of the building curtain wall are as follows: Step A: Drill holes on the exterior wall surface of the building according to the dimensions of the building curtain wall. Two holes are set for each building curtain wall. Step B: Install the grooved positioning body to the exterior wall surface of the building; Step C: Adjust the spacing between the two grooved positioning bodies according to the dimensions of the building curtain wall; Step D: Install the pre-embedded connecting rod in the grooved positioning body, and lock it in place with the axial anti-deviation seat and locking nut; Step E: Fit the upper end of the building curtain wall onto the outside of the groove-shaped positioning body and the pre-embedded connecting rod to position the building curtain wall.
[0014] As a preferred option, the specific steps of step B include: d1, slide the limiting sleeve in the mounting groove plate and align it with the drilling position on the exterior wall of the building; d2, Install positioning teeth on the ear plate of the connecting seat. The positioning teeth mesh with the hollow tooth plate to fix the position of the limiting sleeve and insert it into the drill hole in the building exterior wall. d3, the snap-fit rod is inserted into the through hole of the limit pressure seat, and finally the threaded rod and the lock nut are screwed together; d4, Tighten the locking nut on the threaded rod, and the snap-fit rod will rotate while moving axially inward inside the limiting sleeve; d5, the first swing bar rotates to the guide groove of the limiting sleeve and extends outward, and the first swing bar is tightly attached and anchored to the inner wall of the drill hole in the building exterior wall.
[0015] Preferably, in step E, the upper part of the building curtain wall is positioned and engaged with the positioning plate by multiple positioning teeth. The threaded rod passes through the drilled hole in the building curtain wall. At this time, the building curtain wall pushes the second swing bar, causing the bottom end of the second swing bar to move the mounting slide in and out of the limiting unit groove of the central tie rod, thereby satisfying the requirement that the front end of the threaded rod be inserted into the inner side of the building curtain wall. Then, the support spring drives the mounting slide to reset through the support of the baffle. Thus, the second swing bar can automatically limit the building curtain wall under the support of the mounting slide, effectively maintaining the stable connection between the engaging rod and the building curtain wall.
[0016] In summary, the present invention has the following beneficial effects: 1. This invention uses an automatic limiting unit at the exposed end of the pre-embedded connecting rod to automatically lock and limit the building curtain wall, simplifying the installation process. The synchronous connection mechanism precisely adjusts the installation spacing of multiple slotted positioning bodies, enabling the installation of building curtain walls of different sizes. The axial anti-offset seat effectively prevents radial displacement of the pre-embedded connecting rod during installation and use. The locking nut, in conjunction with the axial anti-offset seat, ensures the stability of the connection between the pre-embedded connecting rod and the building exterior wall, improving the overall stability and safety of the curtain wall.
[0017] 2. The limiting sleeve provides a stable installation foundation and precise positioning for the entire embedded connecting rod. During installation, the snap-fit rod can move accurately along the limiting sleeve, working in conjunction with the axial anti-deviation seat to avoid radial offset and ensure the accuracy of the embedded connecting rod installation position.
[0018] 3. The guide groove provides a unidirectional limiting reference for the first swing bar group on the snap-fit rod, which improves the installation stability of the entire curtain wall embedded part system. The circular array design of the guide groove ensures that after the first swing bar of the internal snap-fit rod extends, the entire device is subjected to uniform force in all directions inside the building exterior wall, which can better distribute the load transmitted from the building curtain wall and reduce local stress concentration.
[0019] 4. The building curtain wall pushes the second swing bar, causing the bottom end of the second swing bar to move the mounting slide inside and outside the limiting unit groove, thereby satisfying the insertion of the front end of the central tie rod into the inner side of the building curtain wall. Then, the support spring drives the mounting slide to elastically reset through the support of the baffle. Thus, the second swing bar can automatically limit the building curtain wall under the support of the mounting slide, effectively maintaining the stable connection between the central tie rod and the building curtain wall.
[0020] 5. The positioning teeth provide precise positioning points for embedding into the building curtain wall, ensuring that the building curtain wall is accurately installed in the predetermined position. The slotted positioning body can be adjusted within a certain range according to the actual situation when installing the slotted positioning body through the waist-shaped mounting holes to adapt to the installation requirements. At the same time, the two hollow toothed plates provide a reference for anti-deviation, further enhancing the stability of the slotted positioning body installation.
[0021] 6. The limiting sleeve and cooperating connecting seat effectively constrain the limiting sleeve in both the axial and radial directions, preventing axial displacement or radial swaying of the limiting sleeve during installation and use. This ensures accurate alignment and stable connection between the embedded connecting rod and the grooved positioning body. The limiting pressure seat can withstand the axial force from the limiting sleeve and the clamping rod and transfer it to the mounting groove plate, enhancing the load-bearing capacity of the entire structure. Furthermore, by rotating the locking nut, the clamping rod and the limiting sleeve are locked, enhancing the connection strength and ensuring the long-term stable operation of the entire embedded connection system.

[0024] To better understand the above-mentioned objectives, features and advantages of the present invention, the present invention will be further described below in conjunction with the accompanying drawings and embodiments.
[0025] Many specific details are set forth in the following description in order to provide a full understanding of the invention. However, the invention may also be practiced in other ways than those described herein. Therefore, the invention is not limited to the specific embodiments disclosed in the following specification. The invention will be further described in detail below with reference to the accompanying drawings.
[0026] Example 1: An embedded component for building curtain walls, such as Figures 1-15 As shown, the structure includes an exterior wall, a curtain wall, and several channel-shaped positioning bodies 1. The exterior wall abuts against the channel-shaped positioning bodies 1 via pre-embedded connecting rods 2. Two pairs of channel-shaped positioning bodies 1 are connected by a synchronous connection mechanism 6. The exposed end of the pre-embedded connecting rod 2 passes through an axial anti-deviation seat 23 and is connected to a locking nut 4. The locking nut 4 can rotate from the exposed end of the pre-embedded connecting rod, so that the pre-embedded end of the pre-embedded connecting rod 2 is fixed inside the exterior wall. An automatic limiting unit 24 is provided at the exposed end of the pre-embedded connecting rod 2. The curtain wall is fixedly installed on the exterior wall via the channel-shaped positioning bodies 1 and the automatic limiting unit 24. Preferably, there are two channel-shaped positioning bodies 1 in a single curtain wall pre-embedded component. The two channel-shaped positioning bodies 1 are connected by the synchronous connection mechanism 6 so that the two channel-shaped positioning bodies 1 are located on the same horizontal line. A single pre-embedded connecting rod 2 is installed on a single channel-shaped positioning body 1.
[0027] If three or more slotted positioning bodies 1 are used, connecting strips 302 need to be welded to both sides of the internal slotted positioning body 1.
[0028] The synchronous connection structure includes a central connecting strip 61, connecting sub-strips 62, and positioning plugs 63. Both ends of the front face of the central connecting strip 61 are slidably connected to the connecting sub-strips 62. The central connecting strip 61 is provided with multiple positioning plugs 63. The ends of the two connecting sub-strips 62 away from the central connecting strip 61 are fixedly connected to the mounting groove plate 11 of the groove-shaped positioning body 1. The connecting sub-strips 62 have sliding grooves that are adapted to the positioning plugs 63. The multiple positioning plugs 63 are linearly arranged on the central connecting strip 61. The distance between the two groove-shaped positioning bodies 1 can be finely adjusted according to the size of the building curtain wall.
[0029] like Figure 1 , Figure 8 , Figure 7 and Figure 10 As shown, the pre-embedded connecting rod 2 includes a snap-fit rod 21 and a limiting sleeve 22. The limiting sleeve 22 is inserted into the exterior wall of the building. The exposed end of the limiting sleeve 22 is connected to the axial anti-deviation seat 23. The snap-fit rod 21 passes through the axial anti-deviation seat 23 and can be slidably installed in the limiting sleeve 22. The limiting sleeve 22 is fixedly installed in the exterior wall of the building through the snap-fit rod 21. The limiting sleeve 22 has a through hole that matches the snap-fit rod 21, so that the snap-fit rod 21 can move smoothly inside it. The exposed end of the limiting sleeve 22 passes through the mounting groove plate 11 and is connected to the axial anti-deviation seat 23 inside the mounting groove plate 11. The axial anti-deviation seat 23 also has a hole at its axis to facilitate the insertion of the snap-fit rod 21.
[0030] like Figure 9 , Figure 10 , Figure 12 , Figure 13As shown, the outer surface of the limiting sleeve 22 has a circular array of guide grooves. The snap-fit rod 21 includes a central pull rod 211, a threaded rod 215, and a limiting rod 217. One end of the central pull rod 211 is fixedly installed with the threaded rod 215, and the other end of the central pull rod 211 is provided with the limiting rod 217. The diameters of the limiting rod 217, the central pull rod 211, and the threaded rod 215 increase sequentially from left to right. The threaded rod 215 is the main driving section of the snap-fit rod 21, which makes the limiting rod 217 and the building exterior wall fit together. The limiting sleeve 22 is anchored, and the other end of the limiting rod 217 is rotatably provided with a limiting ring 212. The limiting ring 212 is rotatably installed at the end of the limiting rod 217 via a bearing. The limiting ring 212 is cross-shaped, and the limiting sleeve 22 also has a cross-shaped sliding groove. The width of the limiting ring 212 is the same as the diameter of the central tie rod 211. The limiting ring 212 is slidably connected inside the limiting sleeve 22. The outer surface of the limiting rod 217 is provided with several top rings 213 and a first swing bar group 214. The top ring 213 and several first swing bar groups 214 all face the limiting ring 212 and are linearly arranged along the axis of the limiting rod 217. The first swing bar groups 214 are fixedly connected to the building exterior wall through guide grooves. The other end of the threaded rod 215 has a limiting unit groove 216. The top ring 213, the first swing bar groups 214 and the limiting rod 217 are umbrella-shaped. The first swing bar groups 214 are composed of multiple first swing bars arranged circumferentially relative to the axis of the limiting rod 217, and extend towards the top ring 213. Inclined and in close contact with the top ring 213, the overall shape unfolds in an umbrella shape. The multiple first swing bars of the first swing adjustment group are matched with the guide grooves on the limiting sleeve 22. When the locking nut 4 rotates counterclockwise to guide the locking rod 21 to move outward, the first swing bar group 214 is obstructed by the guide groove and unfolds. With the top ring 213 as the fulcrum, it automatically swings outward through the tilt angle to achieve rearward opening and anchoring with the building's exterior wall, forming a one-way limit. The top ring 213 and the limiting rod 217 are fixedly connected.
[0031] The limiting sleeve 22 constrains the axial movement path of the locking rod 21, guides the first swing strip group 214 to be anchored to the building's outer wall through the guide groove, and prevents the locking rod 21 from deflecting through the cross-shaped sliding groove and the limiting ring 212.
[0032] like Figure 1 , Figure 7 , Figure 8 , Figure 11 , Figure 12 and Figure 14As shown, the automatic limiting unit 24 is movably installed in the limiting unit slot 216. The automatic limiting unit 24 includes a mounting slide 241, a support spring 242, a baffle 243, and a second swing bar 244. The baffle 243 is fixedly installed in the limiting unit slot 216, and the mounting slide 241 is slidably installed in the limiting unit slot 216. The mounting slide 241 is connected to the baffle 243 through the support spring 242. The bottom end of the second swing bar 244 is rotatably connected to the mounting slide 241 through a pin, so that the second swing bar 244 has a certain degree of swing freedom. 4. The curtain wall is tilted towards the grooved positioning body 1. The curtain wall is fitted onto the end of the threaded rod 215 and abuts against the second swing bar 244. The support spring 242 provides elastic force support for automatic limiting. During the installation of the curtain wall, the support spring 242 is compressed and stores energy. When the curtain wall reaches the correct position, the spring releases energy, so that the second swing bar 244 always maintains the abutment force against the curtain wall. This effectively prevents the curtain wall from loosening or displacing due to external forces during use, enhances the stability and reliability of the limiting, and ensures the safe use of the curtain wall system.
[0033] The baffle 243 is fixedly installed in the limiting unit groove 216, providing stable support and positioning reference for the mounting slide 241 and the support spring 242, limiting the range of motion of the mounting slide 241 and the support spring 242, preventing them from shifting or falling off during the force process, ensuring the normal operation of the automatic limiting unit 24, and improving the reliability of the entire structure.
[0034] The slope of the limiting unit groove 216 abuts against the second swing bar 244.
[0035] like Figure 1 , Figure 2 , Figure 4 , Figure 5 and Figure 7As shown, the grooved positioning body 1 includes a mounting groove plate 11, a positioning plate 12, and a hollow toothed plate 14. An elastic vibration damping pad 5 is snapped onto the outer side of the mounting groove plate 11 near the building's exterior wall. The mounting groove plate 11 is shaped like a folded-down door. When the building curtain wall vibrates due to external factors, the elastic vibration damping pad 5 can absorb and disperse some of the vibration energy, reducing the transmission of vibration to the building's exterior wall. This not only reduces noise caused by vibration and improves the quality of the indoor environment, but also reduces damage to the building curtain wall and the building structure itself, extending their service life. The elastic vibration damping pad 5 has waist holes that match the waist-shaped mounting holes 15 of the mounting groove plate 11. Two hollow toothed plates 14 are fixedly installed on the inner side of the mounting groove plate 11 near the building's exterior wall. A positioning plate 12 is fixedly installed on the top surface of the mounting groove plate 11. Several positioning teeth 13 protrude from the positioning plate 12. The mounting groove 11 between the vibration pad 5 and the hollow toothed plate 14 has a waist-shaped mounting hole 15 in the middle. The two hollow toothed plates 14 are symmetrically installed on both sides of the waist-shaped mounting hole 15. The hollow toothed plate 14 protrudes outward from the inner cavity of the mounting groove 11 and has a toothed groove. It is a certain distance away from the inner side of the mounting groove 11. This distance is consistent with the thickness of the ear plate of the connecting seat 232. The ear plate of the connecting seat 232 is inserted into it. The positioning tooth block 234 is fixed in the toothed groove of the hollow toothed plate 14 by locking knob 233, thereby making the connecting seat 232 mesh and fixed, providing accurate positioning and reliable fixing effect, ensuring that the position of the connecting seat 232 on the hollow toothed plate 14 is accurate and will not move easily due to external force, thus effectively preventing axial displacement and improving the stability of the entire structure. The positioning ruler is a right trapezoid and is arranged in an orderly manner on the positioning plate 12.
[0036] like Figure 1 , Figure 3 , Figure 4 , Figure 6 , Figure 7 , Figure 8 and Figure 12As shown, the axial anti-deviation seat 23 includes a limiting sleeve 231, a connecting seat 232, and a limiting seat 3. The exposed section of the limiting sleeve 22 passes through the waist-shaped mounting hole 15 and is fitted with the limiting sleeve 231. The square section of the limiting sleeve 231 is embedded in the connecting seat 232. The connecting seat 232 is provided with symmetrically arranged ear plates. The connecting seat 232 is inserted into the hollow toothed plate 14 through the ear plates. The ear plates are detachably mounted with positioning tooth blocks 234 through the locking knob 233. The positioning tooth blocks 234 engage with the hollow toothed plate 14. The limiting seat 3 is slidably installed in the mounting groove plate 11 and abuts against the side of the mounting groove plate 11 away from the building's exterior wall. The limiting seat 3 is fitted with... At the ends of the limiting sleeve 231 and the limiting sleeve 22, a locking nut 4 is rotatably installed on the limiting seat 3. The limiting sleeve 231 is cylindrical at both ends and square in the middle. The main body of the connecting seat 232 is square. The square part of the limiting sleeve 231 is embedded in the square body of the connecting seat 232. Thus, the connecting seat 232 cooperates with the limiting sleeve 231 to effectively prevent the limiting sleeve 22 from axially deflecting. The connecting seat 232 is the main mechanical locking. The limiting seat 3 is located at the hook of the mounting groove plate 11 and slides with it. When the locking rod 21 is inserted, the locking nut 4 of the limiting seat 3 is screwed to the threaded rod 215 of the locking rod 21.
[0037] The snap-fit rod 21, the limiting sleeve 22 and the axial anti-deviation seat 23 are coaxially arranged to prevent the tilting of the grooved positioning body 1 or the deformation of the building curtain wall caused by eccentric force from the source. The threaded rod 215 passes through the limiting pressure seat 3 and is connected to the locking nut 4.
[0038] The limiting pressure seat 3 is a convex part consisting of a square base plate and a central cylinder. It has a through hole at the center and a locking nut 4 is rotatably installed at the center of the square base plate.
[0039] Example 2: A construction method for embedded parts in a building curtain wall, such as... Figures 1-15 As shown, it includes the following steps: Step A: Drill holes on the exterior wall surface of the building according to the dimensions of the building curtain wall. Two holes are set for each building curtain wall. The size of the hole drilled in the building exterior wall is consistent with the diameter of the insertion end of the limiting sleeve 22, and the size of the hole drilled in the building curtain wall is consistent with the threaded rod 215 of the snap-fit rod 21.
[0040] Step B: Install the grooved positioning body 1 against the surface of the building's exterior wall; The building exterior wall and the mounting groove plate 11 abut against each other through the elastic damping pad 5. At this time, the drilled holes on the building exterior wall correspond to the waist holes on the elastic damping pad 5 and the waist-shaped mounting holes 15 on the mounting groove plate 11.
[0041] Step C: Adjust the spacing between the two channel-shaped positioning bodies 1 according to the dimensions of the building curtain wall; By using the synchronous connection mechanism 6 and adjusting the spacing between the two mounting slots 11 according to the dimensions of the building curtain wall, the central connecting strip 61 can keep the two connecting sub-strips 62 in a coaxial state through multiple positioning plugs 63. Due to the sliding groove on it, the distance between the two mounting slots 11 can be adjusted by pulling the connecting spokes so that the two mounting slots 11 are on the same horizontal line. Finally, after the adjustment and fixing installation is completed, the central connecting strip 61 can be removed and reused.
[0042] Step D: Install the pre-embedded connecting rod 2 in the grooved positioning body 1, and lock it in place with the axial anti-deviation seat 23 and the locking nut 4; d1, slide the limiting sleeve 22 in the mounting groove plate 11 and align it with the drilling position on the exterior wall of the building; When the positioning tooth block 234 is not installed, the limiting sleeve 22, the limiting pressure sleeve 231, the connecting seat 232 and the limiting pressure seat 3 can be finely adjusted radially to the left and right on the waist-shaped mounting hole 15 so as to align with the drilling hole on the building's exterior wall.
[0043] d2, Install positioning tooth block 234 on the ear plate of connecting seat 232. Positioning tooth block 234 meshes with hollow tooth plate 14 to fix the position of limiting sleeve 22 and insert it into the drill hole of building exterior wall. Remove the positioning tooth block 234 and press it into the tooth groove of the hollow tooth plate 14 to form inter-tooth meshing. Then tighten the locking knob 233 to lock the positioning tooth block 234, thereby maintaining the installation stability of the connecting seat 232 through the hollow tooth plate 14 and the positioning tooth block 234.
[0044] d3, the snap-fit rod 21 is inserted into the through hole of the limit pressure seat 3, and finally the threaded rod 215 is screwed into the locking nut 4; d4, tighten the locking nut 4 on the threaded rod 215, and the snap rod 21 will rotate while moving axially inward inside the limiting sleeve 22; d5, the first swing bar rotates to the guide groove of the limiting sleeve 22 and extends outward, the first swing bar is tightly attached to and anchored to the inner wall of the drilling hole in the building exterior wall.
[0045] The locking nut 4 drives the threaded rod 215, which in turn causes the central tie rod 211 and the limiting rod 217 to rotate axially and move forward inside the limiting sleeve 22. Then, the limiting rod 217 drives multiple first swing bar groups 214 to rotate relative to the limiting sleeve 22 through multiple top rings 213. Then, the front ends of the multiple first swing bars can extend and unfold in the guide groove of the limiting sleeve 22, and fit tightly against the inner wall of the drill hole to realize the end pre-embedding operation.
[0046] The sides of the limiting ring 212 and multiple top rings 213 are inserted into the inner side of the guide groove. The limiting ring 212 and the top ring 213 guide the locking rod 21 to slide axially relative to the limiting sleeve 22. At this time, the drill hole is sealed through the waist-shaped mounting hole 15. Then, under the unidirectional limiting action of multiple first swing bars, the limiting sleeve 22 is kept stably connected to the building exterior wall.
[0047] Step E: Fit the upper end of the building curtain wall onto the outside of the groove-shaped positioning body 1 and the pre-embedded connecting rod 2 to position the building curtain wall; The upper part of the building curtain wall is positioned and engaged with the positioning plate 12 by multiple positioning teeth 13. The threaded rod 215 passes through the drilled hole in the building curtain wall. At this time, the building curtain wall pushes the second swing bar 244, causing the bottom end of the second swing bar 244 to drive the mounting slide 241 to move in and out of the limiting unit groove 216 of the central tie rod 211, thereby satisfying the requirement that the front end of the threaded rod 215 be inserted into the inner side of the building curtain wall. Then, the support spring 242 drives the mounting slide 241 to reset through the support of the baffle 243. Thus, the second swing bar 244 can automatically limit the building curtain wall under the support of the mounting slide 241, effectively maintaining the stable connection between the engaging rod 21 and the building curtain wall.
[0048] When the building curtain wall is fitted onto the end of the threaded rod 215, it will compress the second swing bar 244, which is tilted towards the grooved positioning body 1. After being stressed, the second swing bar 244 rotates around the pin of the mounting slide 241, and at the same time pushes the mounting slide 241 to slide in the limiting unit groove 216 and compress the support spring 242. As the building curtain wall continues to be installed, when the installation is completed, the building curtain wall releases the compression of the second swing bar 244. The elastic force of the support spring 242 will drive the mounting slide 241 to reset, so that the second swing bar 244 resets and tightly abuts against the building curtain wall, thereby realizing the automatic limiting function. There is no need for manual operation of fasteners, which greatly improves the installation efficiency and reduces the installation time and labor costs.
