Description

Technical Field

[0001] This invention belongs to the field of building exterior stone curtain wall technology, and in particular relates to a building stone curtain wall expansion joint structure and its construction method. Background Technology

[0002] Expansion joints in curtain walls are movable connections installed between curtain wall components to accommodate structural thermal expansion and contraction, settlement, earthquakes, and wind loads. Their purpose is to prevent cracks or component damage caused by relative displacement. In stone curtain walls, expansion joints not only release structural displacement but also directly affect the flatness, aesthetics, waterproofing, and long-term durability of the facade. Traditional stone curtain wall expansion joints are recessed structures, where two adjacent stone slabs overlap at the expansion joint, with one slab closer to the building wall than the other. This type of expansion joint structure effectively compensates for asynchronous horizontal displacements between adjacent building structures.

[0003] However, the existing technology has the following technical problems and shortcomings: traditional expansion joints only allow linear displacement parallel to the horizontal direction of the stone slab, and cannot fully release the vibration of the stone slab perpendicular to the wall surface, as well as the asynchronous settlement of the building structure in the vertical direction. When uneven settlement or vibration perpendicular to the wall surface occurs, it can still lead to stress concentration on the stone, resulting in breakage or detachment. In addition, the stone cladding is not neat with the facade, and it is impossible to ensure that all stone slabs on the facade are on the same horizontal plane, affecting the overall aesthetics and uniformity of the curtain wall. Summary of the Invention

[0007] The building stone curtain wall expansion joint structure described above further includes the first stone curtain wall component comprising a first hanger, a second hanger, and a first stone panel. The first hanger is connected to a horizontal curtain wall frame, which is fixed to the outside of the first vertical curtain wall frame via an adapter. The second hanger is connected to the first stone panel via a stone fixing back bolt, and the second hanger is attached to the first hanger.

[0008] The building stone curtain wall expansion joint structure described above further includes a second stone curtain wall component comprising a first hanger, a second hanger, and a second stone panel.

[0010] The building stone curtain wall expansion joint structure of the present invention, as described above, further includes a sloping structure on the side where the first stone panel and the second stone panel are adjacent to each other, and an insertion surface corresponding to the sloping structure is provided on both sides of the expansion joint stone panel.

[0011] The building stone curtain wall expansion joint structure of the present invention, as described above, further includes adhesive strip connectors fixed to the adjacent sides of the first vertical curtain wall frame and the second vertical curtain wall frame, with gusseted adhesive strips connected between the two adhesive strip connectors.

[0012] This invention also provides a construction method for an expansion joint structure in a building stone curtain wall, wherein the expansion joint structure is as described in any of the preceding claims; the construction method includes the following steps: Step 1, pre-assembly installation: The first end of the telescopic rod is vertically installed inside the first mounting bracket, and the second end of the telescopic rod passes through the second mounting bracket; a helical spring is sleeved on the telescopic rod, and one end of the helical spring is fixed to the second end of the telescopic rod by a spring fixing nut; the expansion joint stone panel is connected to the outside of the first mounting bracket; Step 2: Install the first stone curtain wall component onto the first vertical curtain wall frame; preferably, the specific process of step 2 is as follows: fix the horizontal curtain wall frame to the outside of the first vertical curtain wall frame through the adapter, connect the first hanger to the horizontal curtain wall frame, then connect the second hanger to the first stone panel through the stone fixing back bolt, and finally hang the second hanger to the first hanger.

[0014] The beneficial effects of this invention are: By employing the axial engagement of the telescopic rod and the helical spring, the sliding engagement of the guide hole and the horizontal adjusting shaft, and the vertical sliding engagement of the guide pin and the guide groove, the expansion joint structure can simultaneously adapt to horizontal displacement, asynchronous vertical settlement, and vibration perpendicular to the wall surface, effectively overcoming the limitation of traditional expansion joints that can only release displacement in one direction.

In addition to the embodiments described herein, those skilled in the art can employ other obvious technical solutions based on the content disclosed in the claims and specification of this application. These technical solutions include those that make any obvious substitutions and modifications to the embodiments described herein.

[0020] The accompanying drawings in this specification are schematic diagrams to aid in illustrating the concept of the invention, and schematically show the shapes of the various parts and their interrelationships. Please note that, in order to clearly demonstrate the structure of the components in the embodiments of the invention, the drawings are not drawn to the same scale. The same reference numerals are used to indicate the same parts.

[0021] The following combination Figures 1 to 6 This invention describes an embodiment of a building stone curtain wall expansion joint structure and its construction method, which includes: The first vertical curtain wall frame 40 and the second vertical curtain wall frame 50 are separated by an expansion joint. Figure 1In one specific building structure shown, a first vertical curtain wall frame 40 and a second vertical curtain wall frame 50 are fixed to the outer sides of two adjacent building walls, respectively. Preferably, decorative gypsum board 54 and an insulating rock wool layer 53 are fixed to the outer sides of the building walls. In one specific embodiment, adhesive strip connectors 51 are fixed to the adjacent sides of the first vertical curtain wall frame 40 and the second vertical curtain wall frame 50, and accordion adhesive strips 52 are connected between the two adhesive strip connectors 51.

[0022] The first stone curtain wall component 10 and the second stone curtain wall component 30 are connected to the first vertical curtain wall frame 40; the second stone curtain wall component 30 is connected to the second vertical curtain wall frame 50. The stone expansion joint assembly 20 includes a first mounting bracket 21, the outer side of which is connected to the expansion joint stone panel 22; as shown. Figure 5 As shown, the first mounting bracket 21 is hinged to the expansion joint stone panel 22 via a stone fixing bolt 14. At the hinge point, the first mounting bracket can rotate relative to the expansion joint stone panel. The first mounting bracket 21 is provided with a horizontally oriented guide hole 213; the first end of the telescopic rod 28 is vertically installed on the inner side of the first mounting bracket 21; the second mounting bracket 23 is provided with a first guide pin 231 and a second guide pin 232 on one side, and the second end of the telescopic rod 28 passes through the second mounting bracket 23; a helical spring 29 is sleeved on the telescopic rod 28, and one end of the helical spring 29 is fixed to the second end of the telescopic rod 28 via a spring fixing nut 281; after installation, the helical spring is in its original unstretched or uncompressed state. When the expansion joint stone panel is vibrated and moves perpendicular to the curtain wall surface, the end of the telescopic rod connected to the helical spring drives the helical spring to extend or compress. When the external vibration factor is eliminated, the helical spring drives the telescopic rod and the expansion joint stone panel to return to their original positions.

[0023] In a specific embodiment of the expansion joint structure of a building stone curtain wall, such as Figure 5 As shown, the first mounting bracket 21 includes a stone connecting part 211 and a horizontal guide part 212. The stone connecting part 211 is fixed to one side of the horizontal guide part 212.

The length of the expansion joint stone panel is determined according to the actual situation of the engineering design. For example, the height of the expansion joint stone panel can be between 60 cm and 120 cm. The expansion joint stone panel is preferably provided with two first mounting brackets spaced vertically apart, as well as a corresponding number of second mounting brackets, telescopic rods, and helical springs and other supporting components.

[0024] The first sidewalls of the two connecting angle steels 25 are respectively fixed to the corresponding first vertical curtain wall frame 40 and second vertical curtain wall frame 50 by angle steel connecting bolts 26. The bracket guide plate 24 is fixed to the second sidewall of the connecting angle steel 25 by angle steel connecting bolts 26. The bracket guide plate 24 has a guide groove 241 on the side facing the second mounting bracket 23. The position of the guide groove 241 corresponds to the first guide pin 231 and the second guide pin 232 of the second mounting bracket 23. In a preferred embodiment, the width of the guide groove is greater than the diameter of the guide pin, so that the guide pin has a certain range of movement. For example, the guide groove is a T-shaped structure, the guide pin is a T-shaped structure, and the width of the part of the guide pin inserted into the guide groove is less than the width of the guide groove. One end of the horizontal adjustment shaft 27 is fixed to the second sidewall of the connecting angle steel 25, and the other end of the horizontal adjustment shaft 27 faces the first mounting bracket 21. The first mounting bracket 21 is installed on the horizontal adjustment shaft 27 through the guide hole 213. The second mounting bracket 23 is connected to the guide groove 241 of the bracket guide plate 24 by the guide pin.

[0025] In a specific embodiment of the expansion joint structure of a building stone curtain wall, combined with Figure 1 and Figure 3 As shown, the first stone curtain wall assembly 10 includes a first hanger 12, a second hanger 13, and a first stone panel 15. The first hanger 12 is connected to the horizontal curtain wall frame 11, which is fixed to the outside of the first vertical curtain wall frame 40 via an adapter 41. The second hanger 13 is connected to the first stone panel 15 via a stone fixing back bolt 14, and is attached to the first hanger 12. The second stone curtain wall assembly 30 includes a first hanger 12, a second hanger 13, and a second stone panel 35. The first hanger 12 is connected to the horizontal curtain wall frame 11, which is fixed to the outside of the second vertical curtain wall frame 50 via an adapter 41. The second hanger 13 is connected to the second stone panel 35 via a stone fixing back bolt 14, and is attached to the first hanger 12.

[0026] like Figure 1 As shown, after installation, the expansion joint stone panel 22 is located between the first stone panel 15 and the second stone panel 35, and the outer surfaces of the first stone panel 15, the expansion joint stone panel 22, and the second stone panel 35 are on the same plane. In a preferred embodiment, the first stone panel 15 and the second stone panel 35 are respectively provided with inclined structures on their adjacent sides, and the two sides of the expansion joint stone panel 22 are respectively provided with insertion surfaces corresponding to the inclined structures.

[0027] This invention also provides a construction method for an expansion joint structure in a building stone curtain wall, wherein the expansion joint structure in the building stone curtain wall is any of the above embodiments; the construction method includes the following steps: Step 1, pre-assembly installation: The first end of the telescopic rod 28 is vertically installed inside the first mounting bracket 21, and the second end of the telescopic rod 28 passes through the second mounting bracket 23; the helical spring 29 is sleeved on the telescopic rod 28, and one end of the helical spring 29 is fixed to the second end of the telescopic rod 28 by the spring fixing nut 281; the expansion joint stone panel 22 is connected to the outside of the first mounting bracket 21. Step 2: Install the first stone curtain wall component 10 onto the first vertical curtain wall frame 40; specifically: fix the horizontal curtain wall frame 11 to the outside of the first vertical curtain wall frame 40 through the adapter 41, connect the first hanger 12 to the horizontal curtain wall frame 11, then connect the second hanger 13 to the first stone panel 15 through the stone fixing back bolt 14, and finally hang the second hanger 13 onto the first hanger 12.

[0028] Step 3: The first sidewall of the connecting angle steel 25 is fixed to the corresponding first vertical curtain wall frame 40 and second vertical curtain wall frame 50 by angle steel connecting bolts 26; the bracket guide plate 24 is fixed to the second sidewall of the connecting angle steel 25 by angle steel connecting bolts 26; one end of the horizontal adjustment shaft 27 is fixed to the second sidewall of the connecting angle steel 25. Step 4: Install the pre-components from Step 1 onto the horizontal adjustment shaft 27 and the bracket guide plate 24. Insert the horizontal adjustment shaft 27 into the guide hole 213 provided in the first mounting bracket 21. Insert the first guide pin 231 and the second guide pin 232 into the corresponding guide grooves 241 on the bracket guide plate 24, respectively. Step 5: Install the second stone curtain wall component 30 onto the second vertical curtain wall frame 50. Specifically: Fix the horizontal curtain wall frame 11 to the outside of the second vertical curtain wall frame 50 via the adapter 41, connect the first hanger 12 to the horizontal curtain wall frame 11, then connect the second hanger 13 to the second stone panel 35 via the stone fixing back bolt 14, and finally hang the second hanger 13 onto the first hanger 12.

[0029] When one of the two adjacent building walls moves horizontally, it will cause the corresponding first vertical curtain wall frame 40 or second vertical curtain wall frame 50 to move synchronously. At this time, the corresponding horizontal adjustment shaft moves horizontally within the guide hole of the first mounting bracket, thus maintaining the relative stability of the position of the expansion joint stone panel 22. When the stone panel vibrates perpendicular to the wall surface, the expansion joint stone panel can move slightly along the axis of the telescopic rod. When the vibration stops, the expansion joint stone panel is reset by the telescopic rod and the helical spring. When the two adjacent building structures experience asynchronous settlement in the vertical direction, the guide groove of the corresponding bracket guide plate moves downward relative to the guide pin. At this time, the position of the second mounting bracket itself is relatively stable, thereby maintaining the stability of the height position of the expansion joint stone panel. In summary, the expansion joint structure of the present invention can ensure the safety of the curtain wall while maintaining the appearance of the facade when the building wall moves or vibrates in the corresponding direction.

[0030] The technical features disclosed above are not limited to the combinations of the disclosed features with other features. Those skilled in the art can also make other combinations of the technical features according to the purpose of the invention to achieve the purpose of the invention.
