Description

Technical Field

[0001] This utility model relates to the field of building curtain wall technology, and in particular to a hook-type hanger for large building curtain walls. Background Technology

[0002] In the field of modern architecture, building curtain walls have become a core component of the facade design of high-rise and large public buildings due to their advantages such as aesthetic decoration, energy saving and heat insulation and enhancement of the overall texture of the building. The stable installation of the curtain wall system depends on the hanging structure, which, as a key component connecting the curtain wall panels and the main structure of the building, directly determines the safety, durability and construction efficiency of the curtain wall.

[0003] In curtain wall mounting systems, angle steel plates are the core components that directly connect to the curtain wall panels. Their installation orientation must match the panel laying requirements (e.g., horizontal splicing, vertical splicing). However, existing mounting systems often use an integrated fixed structure for the angle steel plates, which lacks flexibility in installation orientation, resulting in different installation positions requiring angle steel plates with different structures. At the same time, most mounting systems only transfer loads through single-point bolt connections, failing to construct a stable support structure that can withstand multi-directional forces. This not only results in poor installation stability but also makes the connection nodes prone to loosening and unable to withstand complex external forces. In view of this, this application proposes a hook-and-loop mounting system for large building curtain walls. Utility Model Content

[0004] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a hook-type hanger for large building curtain walls to solve the problems mentioned in the background technology.

The first mating plate is inserted into the mating groove of the horizontal part of the fixing frame. A connecting plate is installed on the side of the first mating plate and fits against the outer side of the horizontal part of the fixing frame. A plate groove is provided at the end of the connecting plate away from the fixing frame. Angle steel plate, set as an inclined T-shape, with the horizontal and vertical parts of the angle steel plate adjustablely inserted into the plate groove at the end of the connecting plate; The support components are provided in four sets, which are respectively installed at the four corners of the side of the fixed plate and between the top and bottom ends of the connecting plate.

[0006] Optionally, the support components include diagonal braces, vertical bars, and horizontal bars. The diagonal braces are inclined at 45°, the vertical bars are installed vertically at the bottom of the diagonal braces, and the horizontal bars are installed horizontally at the top of the diagonal braces. Screw holes are provided at the ends of both the vertical bars and the horizontal bars.

[0007] Optionally, a first fixing post is installed at each of the four corners of the fixing plate mounting bracket, and a second fixing post is installed at the top and bottom of the connecting plate near the corner of the fixing bracket. Each first fixing post and each second fixing post has a threaded groove at its end. A first locking bolt is inserted into the threaded hole on the bottom vertical rod of the support member, which is threaded to the threaded groove on the corresponding second fixing post. A second locking bolt is inserted into the threaded hole on the top horizontal rod of the support member, which is threaded to the threaded groove on the corresponding first fixing post.

[0008] Optionally, a second mating plate is inserted into the upper and lower half of the mating groove of the vertical part of the fixing frame, and a side support plate located on the outside of the vertical part of the fixing frame is installed on the side of the two second mating plates. The two side support plates abut against the middle position of the top and bottom of the connecting plate, respectively.

[0009] Optionally, the four ends of the fixing frame are provided with first through holes for connecting grooves, and a first bolt is inserted into each first through hole.

[0010] Optionally, both ends of the first docking plate are provided with a first through-hole extending vertically, and the first bolts at both ends of the horizontal part of the fixing frame are respectively inserted into the first through-holes at both ends of the first docking plate. The ends of the two second docking plates away from the first docking plate are provided with a second through-hole extending horizontally, and the first bolts at both ends of the vertical part of the fixing frame are respectively inserted into the second through-holes at both ends of the two second docking plates.

[0011] Optionally, slots are provided at the top of the connecting plate and at the two corners away from the first mating plate. Triangular reinforcing plates are fixedly installed at the four corners of the vertical part of the angle steel plate. An extension plate connected to the horizontal part of the angle steel plate is provided at the end of the four reinforcing plates away from the vertical part of the angle steel plate. The four extension plates are respectively inserted into the corresponding slots on the connecting plate. Mounting holes are provided at the four corners of the horizontal part of the angle steel plate.

[0012] Optionally, two sets of positioning holes are provided at both ends of the top of the horizontal section of the angle steel plate, with three positioning holes in each set. Two through holes are provided at the top of the connecting plate, with the positions of the two through holes aligned with the positions of the two sets of positioning holes on the angle steel plate. A second bolt is inserted through each of the two through holes, and the two second bolts are inserted through the same position in the two sets of positioning holes.

[0013] Optionally, the dimensions of the horizontal section of the angle steel plate are the same as the dimensions of the plate groove, and the side of each reinforcing plate near the connecting plate is in contact with the surface of the connecting plate.

[0014] Optionally, countersunk holes are provided at the four corners of the side of the fixing plate, and fixing bolts are inserted through the four countersunk holes. The beneficial effects of this utility model are: The angle steel plate adopts a "tilted T-shaped" structure. Its horizontal and vertical parts are inserted into the plate groove at the end of the connecting plate by hook-and-loop fasteners. With the multiple sets of positioning holes on the horizontal and vertical parts of the angle steel plate and the second through hole of the connecting plate, the installation orientation and extension length of the angle steel plate can be flexibly adjusted by the detachable locking of the second bolt. With the insertion of the first connecting plate into the connecting groove on the fixing frame (the first connecting plate can be inserted into the connecting groove of the horizontal part or the connecting groove of the vertical part of the fixing frame), the state of the second connecting plate, the connecting plate and the angle steel plate (horizontal or vertical state) can be changed. Compared with the existing integrated fixed angle steel plate, there is no need to replace the special hangers for different curtain wall panel splicing directions (horizontal and vertical), which is suitable for a variety of installation scenarios.

[0015] The support components are connected to the second fixed column of the connecting plate and the first fixed column of the fixed plate via bolt holes on the vertical and horizontal bars, respectively, using hook-type bolts. The 45° inclined diagonal bracing forms a diagonal support between the fixed plate and the connecting plate. Compared with the existing single-point bolt connection, this hook-type support structure distributes the load to the four corners of the fixed plate and the upper and lower ends of the connecting plate, significantly improving its shear and bending resistance. It can effectively resist complex external forces such as strong winds and earthquakes, and prevent the connection nodes from loosening.

[0016] After the second connecting plate is inserted into the hook-type connecting groove of the vertical part of the fixing frame, its outer side support plate directly abuts against the middle position of the top and bottom of the connecting plate, forming longitudinal auxiliary support for the connecting plate. In conjunction with the four support members, it can prevent the middle part of the connecting plate from deforming under stress, and further improve the overall installation accuracy and durability of the curtain wall.

[0018] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0019] Please see Figures 1-7This utility model provides a technical solution: a hook-type bracket for a large building curtain wall, including a fixing plate 1, which is a rectangular plate. A cross-shaped fixing frame 2 is installed on the front side of the fixing plate 1. A U-shaped mating groove is opened on the side of the fixing frame 2 away from the fixing plate 1. A first mating plate 31 is inserted into the mating groove in the horizontal part of the fixing frame 2. The cross section of the first mating plate 31 is the same as and fits the cross section of the mating groove. A connecting plate 32 is installed on the side of the first mating plate 31 and fits against the outer side of the horizontal part of the fixing frame 2. A plate groove 33 is opened at the end of the connecting plate 32 away from the fixing frame 2. An angled bracket is inserted into the plate groove 33. The steel plate 41 and the angle steel plate 41 are set in an inverted T-shape. The horizontal and vertical parts of the angle steel plate 41 are adjustable and inserted into the plate groove 33 at the end of the connecting plate 32. Support members 5 are set at the four corners of the side of the fixed plate 1 and between the top and bottom ends of the connecting plate 32. Assembly is achieved by plugging and hooking, without complicated welding, and the installation and disassembly are convenient. The angle steel plate 41 is hooked and adjustable. The first docking plate 31 is adapted to the convex docking groove, which can flexibly adapt to different curtain wall splicing requirements. The four sets of support members 5 connect the corners of the fixed plate 1 and the upper and lower ends of the connecting plate 32 to form a three-dimensional support, distribute the load, and improve the overall deformation resistance.

[0020] like Figure 2 and Figure 4 As shown, the support member 5 includes a diagonal brace 51, a vertical rod 511, and a horizontal rod 512. The diagonal brace 51 is inclined at 45°. The vertical rod 511 is installed vertically at the bottom end of the diagonal brace 51, and the horizontal rod 512 is installed horizontally at the top end of the diagonal brace 51. Screw holes are provided at the ends of both the vertical rod 511 and the horizontal rod 512. The 45° diagonal brace 51 can efficiently decompose vertical pressure and horizontal wind force, greatly enhancing shear and bending resistance. The screw hole design at the ends of the vertical rod 511 and the horizontal rod 512 allows for quick connection of the fixing plate 1 and the connecting plate 32 through the first locking bolt 52 and the second locking bolt 53, facilitating later maintenance and adjustment.

[0021] like Figure 3 and Figure 4As shown, first fixing posts 12 are installed at the four corners of the mounting bracket 2 on the fixing plate 1, and second fixing posts 37 are installed at the top and bottom of the connecting plate 32 near the corners of the mounting bracket 2. Each first fixing post 12 and each second fixing post 37 has a threaded groove at its end. A first locking bolt 52, which is threaded into the threaded groove on the corresponding second fixing post 37, is inserted into the threaded hole on the bottom vertical rod 511 of the support member 5. A first locking bolt 52, which is threaded into the threaded groove on the corresponding second fixing post 37, is inserted into the threaded hole on the top horizontal rod 512 of the support member 5. The second locking bolt 53 with the threaded groove on the upper screw groove uses the first fixing post 12 on the fixing plate 1 and the second fixing post 37 on the connecting plate 32 as the connection base points of the support member 5. The screw groove and the screw hole are precisely matched. With the cooperation of the first locking bolt 52 and the second locking bolt 53, the support member 5 is accurately positioned and installed to avoid uneven force. The double locking of the first locking bolt 52 (vertical rod 511 and second fixing post 37) and the second locking bolt 53 (horizontal rod 512 and first fixing post 12) ensures the long-term stability of the support structure.

[0022] like Figure 1 , Figure 2 and Figure 3 As shown, a second docking plate 61 is inserted into the upper and lower halves of the vertical docking groove of the fixing frame 2. Side support plates 62 located on the outside of the vertical part of the fixing frame 2 are installed on the sides of the two second docking plates 61. The two side support plates 62 are respectively abutted at the middle position of the top and bottom of the connecting plate 32. After the second docking plate 61 is inserted into the vertical docking groove of the fixing frame 2, the side support plates 62 abut against the middle of the top and bottom of the connecting plate 32, filling the unsupported gap in the middle of the connecting plate 32 and preventing it from bending and deforming due to force. The side support plates 62 and the four sets of support members 5 form a support system at the upper and lower ends and the middle, further dispersing the load and improving the resistance of the hanging parts to external forces.

[0023] like Figure 3 As shown, the four ends of the fixing frame 2 are provided with first through holes 21 that penetrate the docking groove. A first bolt 22 is inserted through each first through hole 21. After the first bolt 22 passes through the first through hole 21, it can lock the position of the first docking plate 31 and the second docking plate 61 in the docking groove.

[0024] like Figure 1 , Figure 2 and Figure 3As shown, both ends of the first docking plate 31 have a vertically penetrating first through-hole 311. The first bolts 22 at both ends of the horizontal part of the fixing frame 2 are respectively inserted into the first through-holes 311 at both ends of the first docking plate 31. The ends of the two second docking plates 61 away from the first docking plate 31 each have a horizontally penetrating second through-hole 611. The first bolts 22 at both ends of the vertical part of the fixing frame 2 are respectively inserted into the second through-holes 611 at both ends of the two second docking plates 61. The first docking plate 31 can be inserted into the docking groove of the horizontal part or the docking groove of the vertical part of the fixing frame 2, depending on the installation situation. The two second docking plates 61 are adapted and adjusted according to the installation position of the first docking plate 31 so that the two side support plates 62 are located on both sides of the connecting plate 32. The first docking plate 31 and the second docking plate 61 in different installation states can be locked in position by the first bolts 22.

[0025] like Figure 5 , Figure 6 and Figure 7 As shown, slots 34 for penetrating the plate groove 33 are provided at the top of the connecting plate 32 and at the two corners away from the first connecting plate 31. Triangular reinforcing plates 42 are fixedly installed at the four corners of the vertical part of the angle steel plate 41. An extension plate connected to the horizontal part of the angle steel plate 41 is provided at the end of the four reinforcing plates away from the vertical part of the angle steel plate 41. The four extension plates are respectively inserted into the corresponding slots 34 on the connecting plate 32. Mounting holes 411 are provided at the four corners of the horizontal part of the angle steel plate 41. The triangular reinforcing plates 42 and the extension plates on the vertical part of the angle steel plate 41 form a "triangular support + extension fixation" structure to enhance the strength of the angle steel plate 41. The angle steel plate 41 restricts the range of movement by inserting the extension plates into the slots 34. The position of the angle steel plate 41 can be fixed by the subsequent second bolt 36.

[0026] like Figure 5 , Figure 6 and Figure 7 As shown, two sets of positioning holes 43 are provided at both ends of the top of the horizontal section of the angle steel plate 41, with three positioning holes 43 in each set. The top of the connecting plate 32 has two through holes 35 that run vertically through each other. The positions of the two through holes 35 are aligned with the positions of the two sets of positioning holes 43 on the angle steel plate 41. A second bolt 36 is inserted through each of the two through holes 35, and the two second bolts 36 are inserted through the same position in the two sets of positioning holes 43. The two sets of positioning holes 43 on the horizontal section of the angle steel plate 41 cooperate with the second through holes 35 on the connecting plate 32. By selecting different positioning holes 43 for locking, the length of the angle steel plate 41 extending out of the plate groove 33 can be flexibly adjusted, improving its installation adaptability.

[0027] like Figure 6 and Figure 7As shown, the dimensions of the horizontal and vertical portions of the angle steel plate 41 are the same as those of the plate groove 33. The side of each reinforcing plate 42 near the connecting plate 32 is in contact with the surface of the connecting plate 32. The dimensions of the horizontal and vertical portions of the angle steel plate 41 are perfectly matched with the plate groove 33, and they fit seamlessly after insertion, avoiding uneven stress. The surface of the reinforcing plate 42 is in contact with the surface of the connecting plate 32, which further increases the contact area, so that the load is evenly transferred and local stress concentration is reduced. The gapless fit can also prevent the angle steel plate 41 from shaking and generating noise and wear, extend the service life of the hanger, and reduce maintenance costs.

[0028] like Figure 1 and Figure 3 As shown, countersunk holes 11 are provided at the four corners of the side of the fixing plate 1, and fixing bolts 111 are inserted through the four countersunk holes 11. The fixing plate 1 can be installed in position through the fixing bolts 111 in the four countersunk holes 11.

[0029] Although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole. The technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
