Description

Technical Field

[0001] This utility model relates to the field of curtain wall installation technology, and in particular to a limiting mechanism for stone curtain walls. Background Technology

[0002] In the field of modern building curtain wall installation technology, curtain walls, as the core decorative and functional components of building exterior walls, are widely used in various buildings such as high-rise buildings and commercial complexes due to their advantages in aesthetics, light transmission, energy saving and modular installation. The limiting mechanism of stone curtain walls, as the key connection carrier between the curtain wall system and the building exterior wall, plays a core role in achieving precise positioning and stable fixing of the curtain wall panels.

[0003] However, existing limiting mechanisms for stone curtain walls still have many technical defects in practical applications, making it difficult to meet the high reliability and practicality requirements of modern buildings for curtain wall systems. Some existing limiting mechanisms for stone curtain walls adopt integrated welding or multi-part cross-fastening designs. When it is necessary to replace damaged curtain wall panels or maintain internal connecting parts, a large number of related structures (such as the overall frame and adjacent curtain wall panels) need to be disassembled. The operation process is cumbersome, which not only increases the labor intensity of construction personnel, but also prolongs the maintenance cycle, resulting in a significant increase in maintenance costs. It is difficult to meet the actual needs of rapid inspection and convenient replacement of curtain walls. Therefore, this application proposes a limiting mechanism for stone 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 limiting mechanism for stone curtain walls to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model is implemented through the following technical solution: a limiting mechanism for a stone curtain wall, including a mounting base, which is provided with four sets arranged in a rectangular array and installed on the exterior wall of the building; The frame consists of several horizontal bars and several vertical columns. The horizontal bars and vertical columns are assembled into a grid shape, and the joints of the frame are respectively fitted onto four sets of rectangular mounting bases. There are four sets of mounting covers, which are respectively fitted onto the joint between the horizontal bar and the vertical column and connected to the corresponding mounting base. The connecting base is provided in four sets, each installed at the center of the outer wall of the mounting cover; The outer frame is fitted between four sets of connecting seats, and curtain wall panels are fixedly installed between the outer frames; The protective components are provided in four sets, located at the four corners of the outer frame, and the protective components can be connected to the corresponding connectors.

[0006] Furthermore, the connecting seat includes a base, a limiting block, and a connecting post. The base is fixedly installed at the center of the outer side of the mounting cover. Four limiting blocks are arranged in a circular array on the side of the base, and each of the four limiting blocks has a first threaded groove on its side. The limiting blocks are set as a quarter circle. The connecting post is fixedly installed at the center of the side of the base and located between the four limiting blocks. A second threaded groove is provided at the end of the connecting post.

[0007] Furthermore, each of the four corners of the outer frame has an arc-shaped notch, and an integrated limiting cover is installed at each of the four corner notches. Each limiting cover has a second countersunk hole on its outer side. The limiting covers at the four corners of the outer frame are tightly fitted onto the corresponding limiting blocks in the four sets of connecting seats. Furthermore, a third bolt connected to the first screw groove is inserted into the second countersunk hole on each limiting cover.

[0008] The protective assembly includes a compression plate, a sealing plate, and a screw. The side of the compression plate has four locking blocks arranged in a circular array. The compression plate is fitted into the notch at the corner of the outer frame and fits against the outside of the limiting cover. The center of the compression plate has a through-hole aligned with the connecting post. The screw is fixedly installed at the center of the side of the sealing plate, and the screw passes through the through-hole and is threaded into the second screw groove at the end of the connecting post. The sealing plate is located at the notch at the corner of the outer frame and fits tightly against the compression plate.

[0009] Furthermore, each third bolt has a slot on its head, the shape of which is adapted to the locking block, and the locking block on the side of the extrusion plate engages in the slot of the corresponding third bolt head.

[0010] Furthermore, interlocking notches are provided at the joints of the crossbars and columns, and four L-shaped limiting angle steels are installed in a circular array on the side of the mounting base. The four limiting angle steels are located at the four corners where the crossbars and columns are joined.

[0011] Furthermore, a third through hole is provided on each of the two right-angled sides of the limiting angle steel, and a first through hole is provided near the notch on the crossbar and column, which is aligned with the third through hole on the corresponding limiting angle steel. The mounting cover is set in a cross shape and is tightly fitted onto the joint of the crossbar and column.

[0012] Furthermore, grooves adapted to the shape of the limiting angle steel are provided at the four corners of the inner wall of the mounting cover, and second through holes aligned with the first through hole are provided at the four ends of the mounting cover. A second bolt is inserted through each second through hole and the corresponding first and third through holes.

[0013] Furthermore, the side of the mounting base has four first countersunk holes arranged in a circular array, and the four first countersunk holes are located between two adjacent limiting angle steels, with a first bolt inserted through each first countersunk hole.

[0014] Furthermore, the corner of the limiting cover near the connecting column is set in an arc shape, and the arc end of the limiting cover fits against the side wall of the connecting column.

[0015] The beneficial effects of this utility model are: The system adopts a layered and detachable structure: the curtain wall panel is fixed to the outer frame, and the outer frame is fixed by the limiting cover and the limiting block of the connecting seat, and by the third bolt. The sealing plate and the extrusion plate of the protective component are also detachably connected by screws and clips. During maintenance, there is no need to disassemble the overall frame such as horizontal bars and columns or adjacent curtain wall panels. Only the sealing plate and the extrusion plate need to be removed in sequence and the third bolt needs to be removed to replace the target curtain wall panel individually. The operation process is simplified, the labor intensity is reduced, and the maintenance cycle is significantly shortened, which perfectly meets the actual needs of rapid inspection and convenient replacement of curtain walls.

[0016] The horizontal bars and vertical columns are precisely spliced ​​into a grid frame through interlocking notches. The joints of the frames are engaged with the rectangular array of mounting bases. The L-shaped limiting angle steel of the mounting bases restrains the frame position from the four corners to prevent misalignment. The cross-shaped mounting cover is fitted with limiting angle steel through a groove, and a second bolt passes through the mounting cover, horizontal bars, vertical columns and limiting angle steel to form a rigid connection between the mounting base, frame and mounting cover. This can improve the stability of the connection between the structures, thereby improving the safety of the curtain wall of high-rise buildings.

[0017] In the protective assembly, the clamping block of the extrusion plate is matched and engaged with the groove of the third bolt head, which can restrict the circumferential rotation of the bolt and prevent the bolt from loosening due to long-term vibration; the sealing plate is tightly attached to the extrusion plate, covering the corner notch of the outer frame, and together with the fitting structure of the extrusion plate and the limit cover, a closed protective space is formed to block rainwater and dust from entering the interior of the connector and prevent corrosion of components such as the bolt groove of the connecting column and the bolt thread.

[0019] 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.

[0020] Please see Figures 1-9This utility model provides a technical solution: a limiting mechanism for a stone curtain wall, including mounting bases 1. Four sets of mounting bases 1 are arranged in a rectangular array and installed on the exterior wall of the building. A frame is erected between the four sets of mounting bases 1. The frame consists of horizontal bars 21 and vertical columns 22, which are assembled into a grid shape. The joints of the frame are respectively engaged with the four rectangularly distributed mounting bases 1. Mounting covers 3, which connect to the corresponding mounting bases 1, are fitted at the joints of the horizontal bars 21 and vertical columns 22. Connecting seats 4 are installed at the center of the outer wall of each mounting cover 3. An outer frame 51 is provided between the four sets of connecting seats 4. Curtain wall panels 52 are fixedly installed between the outer frames 51. Protective components 6 are provided at the four corners of the outer frames 51, and the protective components 6 can be connected to the corresponding connecting seats 4. Through the modular design of four sets of mounting seats 1 rectangular array installation, grid frame assembly, mounting cover 3, connecting seat 4, outer frame 51 and protective components 6 layered cooperation, the curtain wall panels 52 are accurately positioned and stably fixed. It also breaks the limitations of the existing integrated welding or cross fastening design, and provides a detachable structural foundation for the subsequent replacement of curtain wall panels 52 and maintenance of internal components, effectively simplifying the operation process and reducing labor intensity and maintenance costs.

[0021] like Figure 5 and Figure 7 As shown, the connecting seat 4 includes a base 41, a limiting block 42, and a connecting post 43. The base 41 is fixedly installed at the center of the outer side of the mounting cover 3. Four limiting blocks 42 are arranged in a circular array and installed on the side of the base 41. Each of the four limiting blocks 42 has a first threaded groove on its side. The limiting blocks 42 are set as a quarter circle. The connecting post 43 is fixedly installed at the center of the side of the base 41 and located between the four limiting blocks 42. A second threaded groove is opened at the end of the connecting post 43. The limiting blocks 42 can be precisely fitted with the limiting cover 53 of the outer frame 51 to achieve radial limiting and prevent loosening of the connection. The first threaded groove of the limiting block 42 and the second threaded groove of the connecting post 43 provide independent and precise installation interfaces for the outer frame 51 and the protective component 6, respectively. The structure is compact and the functional areas are clearly defined, which not only ensures the stability of the connection, but also provides a clear assembly path for the subsequent disassembly and assembly of components.

[0022] like Figure 5 , Figure 7 and Figure 9As shown, each of the four corners of the outer frame 51 has an arc-shaped notch. An integrated limiting cover 53 is installed at each of the four corner notches of the outer frame 51. Each limiting cover 53 has a second countersunk hole on its outer side. The limiting covers 53 at the four corners of the outer frame 51 are tightly fitted onto the corresponding limiting blocks 42 in the four sets of connecting seats 4. A third bolt 44, connected to the first threaded groove, is inserted into the second countersunk hole on each limiting cover 53. The arc-shaped notches at the corners of the outer frame 51 are adapted to the shape of the connecting seat 4, avoiding... No structural interference; the integrated limiting cover 53 tightly fits the limiting block 42, which can effectively limit the horizontal and vertical displacement of the outer frame 51 and improve positioning accuracy; the second countersunk hole is connected to the third bolt 44 and the first screw groove, which not only realizes the firm and detachable connection between the outer frame 51 and the connecting seat 4, making it convenient for the disassembly and assembly of the outer frame 51 during later maintenance, but also the design of the second countersunk hole can hide the head of the third bolt 44, avoiding the head of the third bolt 44 from protruding, reserving a flat space for the installation of the protective component 6, and ensuring the coordination of the overall structure.

[0023] like Figure 8 As shown, the protective component 6 includes a compression plate 61, a sealing plate 64, and a screw 65. The side of the compression plate 61 is equipped with four locking blocks 62 in a circular array. The compression plate 61 is fitted into the notch at the corner of the outer frame 51 and fits against the outer side of the limiting cover 53. The center of the compression plate 61 has a through-hole 63 aligned with the connecting post 43. The screw 65 is fixedly installed at the center of the side of the sealing plate 64, and the screw 65 passes through the through-hole 63 and is threaded into the second threaded groove at the end of the connecting post 43. The sealing plate 64 is located at the notch at the corner of the outer frame 51 and fits tightly against the compression plate 61.

[0024] like Figure 8 As shown, each third bolt 44 has a slot 441 on its head. The shape of the slot 441 is adapted to the slot 62. The slot 62 on the side of the pressing plate 61 is engaged in the slot 441 on the head of the third bolt 44 corresponding to the position.

[0025] The clamping block 62 of the extrusion plate 61 engages with the groove 441 of the head of the third bolt 44, which can directly prevent the third bolt 44 from loosening and avoid failure of the outer frame 51 connection. The double-layer bonding structure of the extrusion plate 61 with the limiting cover 53 and the sealing plate 64 with the extrusion plate 61 can seal the corner notch of the outer frame 51, prevent dust and rainwater from entering the internal components, and extend the service life. The screw 65 passes through the through-hole 63 and connects to the second screw groove of the connecting column 43, which not only fixes the protective component 6, but also further strengthens the overall connection strength between the outer frame 51 and the connecting seat 4. Moreover, all components can be disassembled without affecting subsequent maintenance operations.

[0026] like Figure 5 and Figure 6As shown, the joints of the crossbar 21 and the column 22 are provided with interlocking notches. The side of the mounting base 1 is equipped with four L-shaped limiting angle steels 13 in a circular array. The four limiting angle steels 13 are located at the four corners where the crossbar 21 and the column 22 are joined.

[0027] like Figure 4 , Figure 5 and Figure 6 As shown, a third through hole 131 is provided on each of the two right-angled sides of the limiting angle steel 13. A first through hole 201 is provided near the notch of the crossbar 21 and the column 22, which is aligned with the third through hole 131 on the corresponding limiting angle steel 13. The mounting cover 3 is set in a cross shape and is tightly fitted at the joint of the crossbar 21 and the column 22.

[0028] like Figure 4 , Figure 5 and Figure 6 As shown, grooves 33 that fit the shape of the limiting angle steel 13 are provided at the four corners of the inner wall of the mounting cover 3, and second through holes 32 that are aligned with the first through hole 201 are provided at the four ends of the mounting cover 3. A second bolt 31 is inserted through each second through hole 32 and the corresponding first through hole 201 and third through hole 131.

[0029] The crossbar 21 and the column 22 are interlocked by notches, which initially improves the stability of the splicing. The four L-shaped limiting angle steels 13 correspond to the splicing corners and, together with the second bolt 31, pass through the second through hole 32, the first through hole 201 and the third through hole 131, which can evenly transfer the force of the frame to the mounting base 1 and avoid excessive local stress. The cross-shaped mounting cover 3 is tightly fitted at the splicing point, and the groove 33 is adapted to the limiting angle steel 13, which not only protects the splicing part from external damage, but also further strengthens the connection through the second bolt 31. The overall structure not only ensures the stability of the frame installation, but also facilitates the individual disassembly and maintenance of the frame components.

[0030] like Figure 5 As shown, the side of the mounting base 1 has four first countersunk holes 11 arranged in a circular array. The four first countersunk holes 11 are located between two adjacent limiting angle steels 13. A first bolt 12 is inserted through each first countersunk hole 11. The first bolt 12 can be used to firmly fix the mounting base 1 to the exterior wall of the building. The design of the first countersunk holes 11 can hide the head of the first bolt 12, so that the head of the first bolt 12 does not protrude and will not interfere with the installation of the frame and the mounting cover 3. This ensures the close fit between the mounting base 1 and the subsequent components, and ensures the compactness and assembly accuracy of the overall structure.

[0031] like Figure 2 and Figure 9 As shown, the corner of the limiting cover 53 near the connecting post 43 is set in an arc shape, and the arc end of the limiting cover 53 is in contact with the side wall of the connecting post 43.

[0032] 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, and 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.
