Description

Technical Field

[0001] This invention belongs to the field of building construction technology, specifically relating to a connection structure and installation method for steel keel of an ultra-long curtain wall. Background Technology

[0002] Curtain walls are the exterior wall cladding of buildings, commonly used in modern large and high-rise buildings as lightweight walls with decorative effects. Curtain walls are subjected to loads such as gravity loads, wind loads, and impact loads. When a curtain wall is subjected to loads, the load is first transferred to the steel frame, which is the main load-bearing component of the curtain wall. Therefore, during the construction of a curtain wall, the design and installation of the steel frame determine the safety performance of the curtain wall. However, in current curtain wall construction processes, once the steel frame is installed between the upper and lower floor slabs, if the steel frame deforms, it cannot be adjusted, greatly affecting the overall safety performance of the curtain wall. Summary of the Invention

[0003] In view of this, the present invention discloses a connection structure and installation method for steel keel of ultra-long curtain walls, the purpose of which is to solve the problem that when the steel keel is deformed during the existing curtain wall construction process, it cannot be adjusted, which greatly affects the overall safety performance of the curtain wall.

[0004] To achieve the above objectives, the present invention provides the following technical solution:

[0005] A steel keel connection structure for an ultra-long curtain wall includes an upper floor slab, a lower floor slab, and a steel keel disposed between the two. An upper connecting part is pre-embedded in the bottom of the upper floor slab. The upper connecting part includes an upper connecting seat, and an installation groove is formed at the bottom of the upper connecting seat. Horizontal transverse grooves are symmetrically arranged on both sides of the installation groove. A transverse seat is slidably connected within each transverse groove, and several horizontally arranged transverse screws are rotatably connected between adjacent transverse seats. Horizontal longitudinal grooves are symmetrically arranged on the remaining two sides of the installation groove. A longitudinal seat is slidably connected within each longitudinal groove, and several horizontally arranged longitudinal screws are rotatably connected between adjacent longitudinal seats. The longitudinal screws are perpendicular to the transverse screws. An upper mounting seat is provided in the installation groove to connect to the upper end of the steel keel. Both the longitudinal and transverse screws are threadedly connected to the upper mounting seat. A lower connecting part for connecting to the lower end of the steel keel is pre-embedded in the bottom of the lower floor slab.

[0006] In this solution, when the steel keel undergoes horizontal deformation, the bottom of the steel keel is kept fixed by the lower connecting part. Then, by simultaneously rotating all the longitudinal screws, the mounting seat moves horizontally longitudinally through the transverse screws, or by rotating all the transverse screws, the mounting seat moves horizontally laterally through the longitudinal screws, thereby driving the upper mounting seat to move horizontally in any direction. This, in turn, causes the top of the steel keel to move horizontally synchronously, thus promoting the restoration of the steel keel's horizontal deformation. The longitudinal screws, transverse screws, and upper mounting seat have self-locking capabilities. When there is no external force driving the longitudinal screws and transverse screws to rotate, the upper mounting seat cannot move horizontally. The entire operation process is simple and quick.

[0007] Furthermore, the lower connecting part includes a lower connecting seat pre-embedded in the lower floor slab. The top of the lower connecting seat has a vertical sliding groove. An adjusting screw is rotatably connected to the bottom of the sliding groove. An adjusting seat that is threadedly connected to the adjusting screw is slidably connected in the sliding groove, and the adjusting seat cannot rotate. The top of the adjusting seat is ball-jointed to a lower mounting seat that is connected to the lower end of the steel keel. A support rod is ball-jointed to the periphery of the lower mounting seat. A fixing rod is slidably sleeved at the end of the support rod along its axial direction. The other end of the fixing rod is inclinedly hinged to the adjusting seat. A pin for locking the support rod is provided on the side wall of the fixing rod.

[0008] In this solution, when the steel keel undergoes longitudinal deformation, simply rotating the adjusting screw causes the adjusting seat to move vertically, which in turn moves the bottom of the steel keel vertically, causing it to stretch or compress and eventually restore its vertical deformation. When verticality adjustment is needed, the pin on the fixing rod is removed, and the longitudinal or transverse screw is rotated to cause the top of the moving steel keel to move horizontally. This causes the steel keel to deflect around the ball joint connection point between the lower mounting base and the adjusting seat, thus adjusting its verticality. After adjustment, the pin is reinstalled to restore the support and fixation of the lower mounting base, thereby restoring the fixation of the bottom of the steel keel. This solution allows for adjustment of the verticality and longitudinal deformation of the steel keel, ensuring that it meets design requirements and thus guaranteeing the overall safety performance of the curtain wall.

[0009] Furthermore, the upper connecting seat sidewall is ball-jointed with several evenly distributed diagonal braces, the ends of the diagonal braces are provided with coaxial grooves, and support rods are slidably connected to each groove coaxially. The ends of the support rods are ball-jointed to the upper mounting seat sidewall; the ends of the diagonal braces are provided with limiting pins for locking the support rods.

[0010] In this solution, when the limit pin locks the support rod, the support rod and the diagonal brace are used to support and fix the upper mounting seat, thereby improving the stability of the upper mounting seat and preventing the upper mounting seat from moving horizontally during construction, which would cause deformation of the steel keel.

[0011] Furthermore, each of the longitudinal screws is fixed with a coaxial transmission gear, and adjacent transmission gears mesh with each other; each of the transverse screws is fixed with a coaxial connecting gear, and adjacent connecting gears mesh with each other.

[0012] The transmission gears and linkage gears work together to make all longitudinal screws or all transverse screws rotate synchronously, thus avoiding any impact on the movement of the upper mounting base.

[0013] Furthermore, the upper mounting base includes a base body threadedly connected to the longitudinal screw and the transverse screw, and a rotating part coaxially rotatably connected to the bottom of the base body. The steel keel is connected to the bottom end of the rotating part, and the support rod is ball-jointed to the rotating part. The rotating part has a plurality of limiting holes evenly distributed on it, and the base body is provided with a limiting rod that engages with the limiting holes.

[0014] When the steel keel undergoes torsional deformation, keep the bottom of the steel keel stationary, remove the limiting pin on the diagonal brace and the limiting rod on the rotating part, and drive the rotating part to rotate, thereby causing the top of the steel keel to twist and restore the torsional deformation; after the adjustment is completed, simply reinstall the limiting pin and the limiting rod; the whole operation process is simple and quick.

[0015] An installation method for a steel keel connection structure for an ultra-long curtain wall includes the following steps:

[0016] 1) Floor slab pouring: The upper and lower floor slabs are poured separately, and the upper and lower connecting parts are pre-embedded and installed;

[0017] 2) Steel keel installation: Fix the upper end of the steel keel to the bottom end of the rotating part in the upper connecting part; fix the lower end of the steel keel to the top of the lower mounting base in the lower connecting part;

[0018] 3) Adjustment of horizontal deformation of steel keel: When horizontal deformation occurs after the steel keel is installed, keep the lower mounting base at the bottom of the steel keel fixed, remove the limit pin on the diagonal brace, so that the support rod can slide relative to the diagonal brace; then rotate the longitudinal screw or the transverse screw to drive the upper mounting base to move horizontally in any direction, thereby causing the top of the steel keel to move horizontally synchronously, which helps the steel keel to restore horizontal deformation; after the adjustment is completed, reinstall the limit pin to lock the support rod, so that the support rod and diagonal brace can maintain their supporting and fixing function on the upper mounting base;

[0019] 4) Steel keel torsional deformation adjustment: When the steel keel undergoes torsional deformation, keep the rest of the structure still and only remove the limit pin on the diagonal brace and the limit rod on the rotating part. By driving the rotating part to rotate, the top of the steel keel will be twisted, thus restoring the torsional deformation. After the adjustment is completed, reinstall the limit pin and limit rod to restrict the rotation of the rotating part relative to the base body, while also using the support rod and diagonal brace to support and fix the rotating part.

[0020] 5) Vertical deformation adjustment of steel keel: When the steel keel undergoes longitudinal deformation, it is only necessary to drive the rotation of the adjusting screw, thereby driving the adjusting seat to move vertically, which in turn drives the bottom end of the steel keel to move vertically, causing the steel keel to be stretched or compressed vertically, and thus prompting the steel keel to restore its vertical deformation.

[0021] 6) Steel keel verticality adjustment: When the steel keel needs to be adjusted vertically, remove the limiting pin on the diagonal brace and the pin on the fixing rod. Then, by rotating the longitudinal screw or the transverse screw, the top of the moving steel keel moves horizontally synchronously. This causes the steel keel to deflect around the ball joint connection point between the mounting base and the adjusting base, thereby achieving the verticality adjustment of the steel keel. After the adjustment is completed, reinstall the limiting pin and the pin to restore the support and fixation of the top and bottom of the steel keel.

[0022] 7) Subsequent construction: After the steel keel adjustment is completed, continue the remaining construction until the curtain wall installation is completed.

[0023] Other advantages, objectives, and features of the invention will be set forth in the following description and will be apparent to those skilled in the art in some respects, or may be learned by practice of the invention. The objectives and other advantages of the invention can be realized and obtained through the following description. Attached Figure Description

Detailed Implementation

[0030] like Figures 1-4 As shown:

[0031] A connection structure for an ultra-long curtain wall steel keel 9 includes an upper floor slab 1, a lower floor slab 2, and a steel keel 9 disposed between the two. An upper connecting part is pre-embedded at the bottom of the upper floor slab 1. The upper connecting part includes an upper connecting seat 3. An installation groove is formed at the bottom of the upper connecting seat 3. Horizontal transverse grooves are symmetrically arranged on both sides of the installation groove. A transverse seat 4 is slidably connected within each transverse groove. Several horizontally arranged transverse screws 5 are rotatably connected between adjacent transverse seats 4. Horizontal longitudinal grooves are symmetrically arranged on the remaining two sides of the installation groove. Longitudinal seats 6 are slidably connected within each longitudinal groove. Several horizontally arranged longitudinal screws 7 are rotatably connected between adjacent longitudinal seats 6. The longitudinal screws 7 are perpendicular to the transverse screws 5. An upper mounting seat connected to the upper end of the steel keel 9 is disposed within the installation groove. Both the longitudinal screws 7 and the transverse screws 5 are threadedly connected to the upper mounting seat. A lower connecting part for connecting to the lower end of the steel keel 9 is pre-embedded at the bottom of the lower floor slab 2.

[0032] In this solution, when the steel keel 9 undergoes horizontal deformation, the bottom of the steel keel 9 is kept fixed by the lower connecting part. Then, by simultaneously rotating all the longitudinal screws 7, the mounting seat moves horizontally longitudinally through the transverse screw 5 to drive the transverse seat 4. Alternatively, by rotating all the transverse screws 5, the mounting seat moves horizontally laterally through the longitudinal screws 7 to drive the longitudinal seat 6. This drives the upper mounting seat to move horizontally in any direction, thereby causing the top of the steel keel 9 to move horizontally synchronously, thus restoring the horizontal deformation of the steel keel 9. The rotation of the longitudinal screws 7 and transverse screws 5 in this solution can be driven by a motor, which is a conventional technical method and is therefore not shown in the figure. The longitudinal screws 7 and transverse screws 5 have a self-locking capability with the upper mounting seat. When there is no external force driving the longitudinal screws 7 and transverse screws to rotate, the upper mounting seat cannot move horizontally. The entire operation process is simple and quick.

[0033] In this embodiment, the lower connecting part includes a lower connecting seat 10 pre-embedded in the lower floor slab 2. The top of the lower connecting seat 10 is provided with a vertical sliding groove. The bottom of the sliding groove is rotatably connected to a vertically arranged adjusting screw 11. An adjusting seat 12 is slidably connected in the sliding groove and threadedly connected to the adjusting screw 11, and the adjusting seat 12 cannot rotate. The top of the adjusting seat 12 is ball-jointed to a lower mounting seat 13 connected to the lower end of the steel keel 9. The lower mounting seat 13 is ball-jointed to a support rod 14. A fixing rod 15 is slidably sleeved on the end of the support rod 14 along its axial direction. The other end of the fixing rod 15 is inclinedly hinged to the adjusting seat 12. A pin 16 for locking the support rod 14 is provided on the side wall of the fixing rod 15.

[0034] In this scheme, when the steel keel 9 undergoes longitudinal deformation, it is only necessary to drive the rotation of the adjusting screw 11, thereby causing the adjusting seat 12 to move vertically, which in turn causes the bottom end of the steel keel 9 to move vertically, causing the steel keel 9 to be stretched or compressed vertically, and thus prompting the steel keel 9 to restore its vertical deformation. The rotation of the adjusting screw 11 in this scheme can be driven by a motor, which is a conventional technical means, so it is not shown in the figure. When the steel keel 9 needs to be adjusted for verticality, the pin 16 on the fixing rod 15 is removed, and then the longitudinal screw 7 or the transverse screw 5 is rotated to make the top end of the moving steel keel 9 move horizontally synchronously, thereby causing the steel keel 9 to deflect around the ball joint connection point between the lower mounting seat 13 and the adjusting seat 12, thus achieving the verticality adjustment of the steel keel 9. After the adjustment is completed, the pin 16 is reinstalled to restore the support and fixation of the lower mounting seat 13, thereby restoring the fixation of the bottom end of the steel keel 9. In this solution, the verticality and longitudinal deformation of the steel keel 9 can be adjusted to ensure that the steel keel 9 meets the design requirements, thereby ensuring the overall safety performance of the curtain wall.

[0035] In this embodiment, the upper connecting seat 3 is connected to a plurality of evenly distributed diagonal bracing rods 17 by ball joints on the side wall. The ends of the diagonal bracing rods 17 are provided with coaxial grooves, and support rods 18 are slidably connected to the grooves on the same axis. The ends of the support rods 18 are connected to the ball joints on the side wall of the upper mounting seat. The ends of the diagonal bracing rods 17 are provided with limiting pins 19 for locking the support rods 18.

[0036] In this solution, when the limit pin 19 locks the support rod 18, the support rod 18 and the diagonal brace 17 are used to support and fix the upper mounting seat, thereby improving the stability of the upper mounting seat and preventing the upper mounting seat from moving horizontally during construction, which would cause the steel keel 9 to deform.

[0037] In this embodiment, each of the longitudinal screws 7 is fixed with a coaxial transmission gear, and adjacent transmission gears mesh with each other; each of the transverse screws 5 is fixed with a coaxial connecting gear, and adjacent connecting gears mesh with each other.

[0038] The transmission gears and linkage gears work together to make all longitudinal screws 7 or all transverse screws 5 rotate synchronously, so as to avoid affecting the movement of the upper mounting base. The transmission gears and linkage gears are conventional technical means, so they are not shown in the figure.

[0039] In this embodiment, the upper mounting base includes a base body 8 threadedly connected to the longitudinal screw 7 and the transverse screw 5, and a rotating part 20 coaxially rotatably connected to the bottom of the base body 8. The steel keel 9 is connected to the bottom end of the rotating part 20, and the support rod 18 is ball-jointed to the rotating part 20. The rotating part 20 has a plurality of limiting holes evenly distributed on it, and the base body 8 is provided with a limiting rod that cooperates with the limiting holes. The limiting rod and the limiting holes cooperate to restrict the rotation of the rotating part 20, which is a conventional technical means, so it is not shown in the figure.

[0040] When the steel keel 9 undergoes torsional deformation, keep the bottom of the steel keel 9 still, remove the limiting pin 19 on the diagonal brace 17 and the limiting rod on the rotating part 20, drive the rotating part 20 to rotate, thereby causing the top of the steel keel 9 to twist, which can restore the torsional deformation; after the adjustment is completed, simply reinstall the limiting pin 19 and the limiting rod; the whole operation process is simple and quick.

[0041] An installation method for a steel keel 9-connection structure for an ultra-long curtain wall includes the following steps:

[0042] 1) Floor slab pouring: Pour the upper floor slab 1 and the lower floor slab 2 separately, and pre-install the upper and lower connecting parts;

[0043] 2) Steel keel 9 installation: Fix the upper end of the steel keel 9 to the bottom end of the rotating part 20 in the upper connecting part; fix the lower end of the steel keel 9 to the top end of the lower mounting base 13 in the lower connecting part;

[0044] 3) Horizontal Deformation Adjustment of Steel Keel 9: When horizontal deformation occurs after the steel keel 9 is installed, keep the lower mounting base 13 at the lower end of the steel keel 9 fixed, remove the limiting pin 19 on the diagonal brace 17, so that the support rod 18 can slide relative to the diagonal brace 17; then, by rotating the longitudinal screw 7 or the transverse screw 5, the upper mounting base can be driven to move horizontally in any direction, thereby causing the top of the steel keel 9 to move horizontally synchronously, which can promote the steel keel 9 to restore horizontal deformation; after the adjustment is completed, reinstall the limiting pin 19 to lock the support rod 18, so that the support rod 18 and the diagonal brace 17 can maintain the support and fixation of the upper mounting base;

[0045] 4) Adjustment of torsional deformation of steel keel 9: When steel keel 9 undergoes torsional deformation, keep the rest of the structure still and only remove the limiting pin 19 on the diagonal brace 17 and the limiting rod on the rotating part 20. By driving the rotating part 20 to rotate, the top of the steel keel 9 will be twisted, thus restoring the torsional deformation. After the adjustment is completed, the limiting pin 19 and the limiting rod will be reinstalled to restrict the rotation of the rotating part 20 relative to the base 8, while the support rod 18 and the diagonal brace 17 will also support and fix the rotating part 20.

[0046] 5) Vertical deformation adjustment of steel keel 9: When steel keel 9 undergoes longitudinal deformation, it is only necessary to drive the rotation of the adjusting screw 11, thereby driving the adjusting seat 12 to move vertically, thereby driving the bottom end of steel keel 9 to move vertically, so that steel keel 9 is stretched or compressed vertically, and thus prompting steel keel 9 to restore vertical deformation.

[0047] 6) Verticality adjustment of steel keel 9: When the verticality of steel keel 9 needs to be adjusted, remove the limiting pin 19 on the diagonal brace 17 and the pin 16 on the fixing rod 15. Then, by rotating the longitudinal screw 7 or the transverse screw 5, the top of the moving steel keel 9 moves horizontally synchronously. This causes the steel keel 9 to deflect around the ball joint connection point between the mounting base 13 and the adjusting base 12, thereby achieving the verticality adjustment of steel keel 9. After the adjustment is completed, reinstall the limiting pin 19 and the pin 16 to restore the support and fixation of the top and bottom of steel keel 9.

[0048] 7) Subsequent construction: After the steel keel 9 is adjusted, continue the remaining construction until the curtain wall installation is completed.

[0049] Finally, it should be noted that the above preferred embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit it. Although the present invention has been described in detail through the above preferred embodiments, those skilled in the art should understand that various changes can be made to it in form and detail without departing from the scope defined by the claims of the present invention.
