Technical Field

[0001] This utility model relates to the technical field of T-shaped keel connectors, and in particular to a pre-embedded curtain wall keel T-shaped connector. Background Technology

[0002] In the field of modern architecture, curtain walls, as an important component of building facades, not only serve to decorate buildings and enhance their aesthetics, but also need to meet multiple performance requirements such as windproofing, rainproofing, heat insulation, and thermal insulation. Curtain wall construction is divided into two methods: pre-embedded installation and post-embedded installation.

[0003] In the installation of embedded curtain walls, the T-shaped connector is a key component that connects the curtain wall keel to the embedded parts of the main structure. Its performance directly affects the installation accuracy, structural stability and service life of the curtain wall system.

[0004] However, when traditional T-type connectors are connected to groove-type embedded parts, the friction between the head of the T-bolt and the inner wall of the embedded part groove is small. When subjected to external forces such as large lateral wind loads, the curtain wall keel is prone to move along the length of the embedded part groove, affecting the safety and stability of the curtain wall connection. Utility Model Content

[0005] To overcome the above deficiencies, this utility model provides a pre-embedded curtain wall keel T-shaped connector, which aims to solve the problem that the curtain wall keel is prone to move along the length direction of the pre-embedded part slot when subjected to external forces such as large lateral wind loads, affecting the safety and stability of the curtain wall connection.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a pre-embedded curtain wall keel T-shaped connector, comprising an embedded part, wherein a rectangular cavity is formed inside the embedded part, and a groove one and a groove two are formed on one side of the embedded part, the groove one and the groove two are connected in the vertical direction, and the rectangular cavity is connected to the groove one and the groove two in the horizontal direction. A plurality of T-bolts are arranged inside the embedded part, one end of the outer wall of the T-bolt passes through the groove one, and a stabilizing ring is slidably connected to the outer wall of one end of the T-bolt. The stabilizing ring is arranged inside the groove one, and a stabilizing component is arranged on one side of the stabilizing ring. One side of the stabilizing component is arranged on the inner wall of the embedded part.

[0007] The above technical solution solves the problem that the curtain wall keel tends to move along the length of the embedded part slot when subjected to large lateral wind loads and other external forces, thus affecting the safety and stability of the curtain wall connection. This is achieved through the sliding connection of T-bolts and stabilizing rings, the connection of stabilizing rings and stabilizing components, and the connection of stabilizing components and embedded parts.

A reinforcing block is fixedly connected to one side of the T-bolt, and a fastening bolt is threadedly connected to one side of the reinforcing block. The outer wall of one end of the fastening bolt passes through both sides of the reinforcing block, and a washer is provided on the outer wall of one end of the fastening bolt. One side of the washer fits against one side of the partition, and an internal hexagonal hole is opened at one end of the fastening bolt.

[0011] Preferably, a guide rod is slidably connected to the outer wall of one end of the partition, and the end of the guide rod away from the fastening bolt passes through a groove.

[0012] Preferably, the embedded part is provided with a limiting rod inside, one side of the limiting rod is fixedly connected to the inner wall of one side of the rectangular cavity, and a sliding groove matching the limiting rod is opened on one side of the T-bolt. The outer wall of the limiting rod and the inner wall of the sliding groove of the T-bolt are both frosted.

[0013] Preferably, the stabilizing component includes a turnbuckle nut, both ends of which are threadedly connected to studs. One end of the stud away from the turnbuckle nut is threadedly connected to one side of the stabilizing ring, and the other end of the stud away from the turnbuckle nut is threadedly connected to the inner wall of the groove.

[0014] Preferably, the stabilizing component includes a limiting block, a tensioning bolt is threaded to one side of the stabilizing ring, the opposite ends of the two tensioning bolts are designed with hemispherical threads, the outer wall of the tensioning bolt is threaded with a limiting nut, the opposite ends of the two tensioning bolts pass through both sides of the limiting block, the two limiting nuts are respectively disposed on both sides of the limiting block, and the outer walls of both sides of the limiting block are in contact with the inner walls of both sides of the groove.

[0015] This utility model has the following beneficial effects: 1.

[0018] 4. In this utility model, the stabilizing components are designed as a tension bolt, a limiting block, and a limiting nut. The position of the limiting block is limited by the interference between the outer wall of the limiting block and the inner wall of the groove. The position of the tension bolt is limited by the threaded connection between the limiting nut and the tension bolt, thereby providing support for the curtain wall and improving the horizontal stability of the curtain wall.

[0021] The technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0022] Example 1: Reference Figure 1 , Figure 2 and Figure 3 This utility model provides an embodiment of a pre-embedded curtain wall keel T-shaped connector, including a pre-embedded part 2. The pre-embedded part 2 has a rectangular cavity 14 inside. The pre-embedded part 2 has a groove 10 and a groove 21 on one side. The groove 10 and the groove 21 are connected in the vertical direction. The rectangular cavity 14 is connected to the groove 10 and the groove 21 in the horizontal direction. A plurality of T-bolts 7 are provided inside the pre-embedded part 2. The outer wall of one end of the T-bolt 7 passes through the groove 10. A stabilizing ring 8 is slidably connected to the outer wall of one end of the T-bolt 7. The stabilizing ring 8 is located inside the groove 10. A stabilizing component 4 is provided on one side of the stabilizing ring 8. One side of the stabilizing component 4 is located on the inner wall of the pre-embedded part 2.

[0023] In this embodiment, Figure 1 The orientation is indicated by the front, back, left, and right sides. Specifically, in use, first, fix the embedded part 2 and the casting template together. Then, pour concrete to integrate the embedded part 2 with the wall. Remove the concrete layer on the front side of the embedded part 2, exposing the groove 10. Next, place the T-shaped end of the T-bolt 7 flat, pass it through the middle of the groove 10, and enter the rectangular cavity 14. Then, rotate the T-bolt 7 so that its T-shaped end is placed vertically and fits against the front inner wall of the rectangular cavity 14, thus completing the installation of the T-bolt 7. Finally, put the stabilizing ring 8 on the T-bolt 7. The outer wall of the threaded end slides into the interior of the groove 10, threading one side of the stabilizing component 4 to one side of the stabilizing ring 8, and fixing the other side of the stabilizing component 4 to the inner wall of the embedded part 2, thereby completing the horizontal limiting of the T-bolt 7. Through the adjustment of the stabilizing component 4 itself, the T-bolt 7 can also be moved horizontally, thus solving the problem that when subjected to large lateral wind loads and other external forces, the curtain wall keel is prone to move along the length direction of the embedded part 2 slot, affecting the safety and stability of the curtain wall connection.

[0024] Reference Figure 1 On the other side of the embedded part 2, multiple connectors 1 are fixedly connected.

[0025] Specifically, the design of connector 1 increases its contact area with the wall, thereby helping to improve the stability of embedded part 2.

[0026] Reference Figure 1 Two clamping plates 3 are provided on one side of the embedded part 2, and there are two T-bolts 7. One end of the outer wall of the T-bolt 7 passes through both sides of the clamping plate 3.

[0027] Specifically, by passing two T-bolts 7 through the two clamping plates 3 respectively and fixing the clamping plates 3 with bolts or other fixing methods, the keel is then installed between the two clamping plates 3, thereby achieving the fixing of the curtain wall keel.

[0028] Reference Figure 2 and Figure 3 The inner walls between the upper and lower sides of the embedded part 2 are fixedly connected with partitions 17. The side walls between the two partitions 17 are pre-set with a gap. A reinforcing block 13 is fixedly connected to one side of the T-bolt 7. A fastening bolt 15 is threadedly connected to one side of the reinforcing block 13. The outer wall of one end of the fastening bolt 15 passes through both sides of the reinforcing block 13. A washer 16 is provided on the outer wall of one end of the fastening bolt 15. One side of the washer 16 fits against one side of the partition 17. An internal hexagonal hole 18 is opened at one end of the fastening bolt 15.

[0029] Specifically, when the T-shaped end of the T-bolt 7 is placed inside the rectangular cavity 14, the outer wall of the reinforcing block 13 passes through the groove 11 and enters the interior of the rectangular cavity 14. During this process, there is a pre-set gap between the outer wall of the reinforcing block 13 and the inner wall of the groove 11. When the T-shaped end of the T-bolt 7 is rotated to fit against the front inner wall of the rectangular cavity 14, so that the threaded hole on the reinforcing block 13 is aligned with the threaded end of the fastening bolt 15, an Allen wrench of the corresponding type is used to pass through the threaded hole of the reinforcing block 13 and insert into the interior of the Allen hole 18 to thread the reinforcing block 13 and the fastening bolt 15 together, but not to fix them. Then, the T-bolt 7 is moved, which moves the fastening bolt 15 to the designated position. Then, the fastening bolt 15 and the reinforcing block 13 are fixed. At this time, the stability of the T-bolt 7 is further improved by the fit of the partition plate 17 and the washer 16, which helps to improve the load-bearing capacity of the embedded part 2.

[0030] Reference Figure 1 and Figure 3 A guide rod 6 is slidably connected to one end of the outer wall of the partition 17, and the end of the guide rod 6 away from the fastening bolt 15 passes through the groove 10.

[0031] Specifically, when making the threaded connection between the reinforcing block 13 and the fastening bolt 15, the threaded end of the fastening bolt 15 can be adjusted by holding one end of the guide rod 6 with your hand, so that the threaded hole of the reinforcing block 13 and the threaded end of the fastening bolt 15 are aligned, thereby helping to improve the installation efficiency of the curtain wall keel.

[0032] Reference Figure 2 and Figure 3The embedded part 2 is provided with a limiting rod 12 inside. One side of the limiting rod 12 is fixedly connected to the inner wall of one side of the rectangular cavity 14. A matching groove for the limiting rod 12 is opened on one side of the T-bolt 7. The outer wall of the limiting rod 12 and the inner wall of the groove of the T-bolt 7 are both frosted.

[0033] Specifically, the vertical positioning of the T-bolt 7 is achieved by the fit between the outer wall of the limiting rod 12 and the inner wall of the groove on the T-bolt 7, and the horizontal stability of the T-bolt 7 is further improved by the frosted design.

[0034] Reference Figure 1 , Figure 2 and Figure 3 The stabilizing component 4 includes a turnbuckle nut 9, with studs 5 threaded to both ends of the turnbuckle nut 9. One stud 5 is threaded to one side of the stabilizing ring 8 at the end away from the turnbuckle nut 9, and the other stud 5 is threaded to the inner wall of the groove 10 at the end away from the turnbuckle nut 9.

[0035] Specifically, when installing the stabilizing component 4, firstly, thread the two studs 5 to both ends of the turnbuckle 9, then thread one of the studs 5 to one side of the stabilizing ring 8. Pass the stabilizing ring 8 through the threaded end of the T-bolt 7 and slide it into the groove 10. By rotating the other stud 5, the end of the stud 5 furthest from the turnbuckle 9 is threaded onto the inner wall of the horizontal side of the groove 10, thus completing the installation of the stabilizing component 4. When fine-tuning of the T-bolt 7 is required, the distance between the two studs 5 can be adjusted by rotating the turnbuckle 9, thereby adjusting the horizontal position of the T-bolt 7. When the curtain wall is subjected to lateral wind loads or external forces, the rigid connection between the turnbuckle 9 and the two studs 5, and the threaded connections between the two studs 5 and the embedded part 2 and the T-bolt 7 respectively, provide support for the curtain wall, preventing it from sliding horizontally, thus improving the safety and stability of the curtain wall connection.

[0036] Example 2: Reference Figure 2 , Figure 4 and Figure 5 The stabilizing component 4 includes a limiting block 20. One side of the stabilizing ring 8 is threaded with a tension bolt 19. The opposite ends of the two tension bolts 19 are designed with hemispherical threads. The outer wall of the tension bolts 19 is threaded with a limiting nut 21. The opposite ends of the two tension bolts 19 pass through both sides of the limiting block 20. The two limiting nuts 21 are respectively set on both sides of the limiting block 20. The outer walls of both sides of the limiting block 20 are in contact with the inner walls of both sides of the groove 10.

[0037] Specifically, in this embodiment, a certain length of one end of the tension bolt 19 is semi-cylindrical, and the outer wall is provided with external threads. When the semi-cylindrical ends of the two tension bolts 19 are joined together, they form a complete threaded column. When installing the stabilizing component 4, the other complete threaded ends of the two tension bolts 19 are respectively threaded to the opposite sides of the two stabilizing rings 8. Then, the rotation angle of the two tension bolts 19 is adjusted so that one end of the two tension bolts 19 is combined into a complete threaded column. Before this, two limit nuts 21 and limit blocks 20 are inserted into one of the tension bolts 19. The limit block 20 is located in the middle of the two limit nuts 21. Then, the limit blocks are moved... The positions of the positioning block 20 and the two limiting nuts 21 are such that the outer wall of the limiting block 20 fits against the inner wall of the groove 11, and the two limiting nuts 21 clamp and fix the limiting block 20 through the threaded connection of the limiting nuts 21 and the tension bolt 19. When the curtain wall is subjected to lateral wind load or external force, the position of the limiting block 20 is limited by the interference between the outer wall of the limiting block 20 and the inner wall of the groove 11, and the position of the tension bolt 19 is limited by the threaded connection of the limiting nuts 21 and the tension bolt 19, so that the two T-bolts 7 cannot move horizontally, thereby supporting the curtain wall and preventing it from sliding horizontally, thus improving the safety and stability of the curtain wall connection.

[0038] Working principle: In use, the T-bolts 7 and stabilizing components 4 are installed first. When the curtain wall is subjected to lateral wind loads or external forces, if the stabilizing component 4 consists of studs 5 and turnbuckles 9, the rigid connection between the turnbuckles 9 and the two studs 5, and the threaded connection between the two studs 5 and the embedded parts 2 and T-bolts 7 respectively, will support the curtain wall and prevent it from sliding horizontally. If the stabilizing component 4 consists of tension bolts 19, limit blocks 20 and limit nuts 21, the interference between the outer wall of the limit block 20 and the inner wall of the groove 11 will limit the position of the limit block 20. The threaded connection between the limit nuts 21 and the tension bolts 19 will limit the position of the tension bolts 19, preventing the two T-bolts 7 from moving horizontally. This will support the curtain wall and prevent it from sliding horizontally, thus solving the problem that the curtain wall keel is prone to move along the length of the groove of the embedded parts 2 when subjected to large lateral wind loads or other external forces, affecting the safety and stability of the curtain wall connection.

[0039] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
