Description

Technical Field

[0001] This invention belongs to the field of large-span steel building design technology, and particularly relates to a fourth-generation residential building with an integrated installation structure of large-span steel and climbing cone. Background Technology

[0002] In fourth-generation housing, a large number of cantilevered balconies are distributed in a staggered manner. Erecting a formwork support system from bottom to top not only consumes a lot of materials, but also delays the dismantling of the scaffolding. Combining steel brackets with the formwork support system, and erecting and dismantling the scaffolding in sections, can effectively solve the above problems.

[0003] Climbing cones are important components in climbing systems used for climbing formwork, climbing scaffolding, and other climbing applications. They mainly consist of a cone and matching embedded parts. The cone is typically a metal component with threads or special grooves, while the embedded parts are pre-embedded in the concrete structure for connection with the cone. The working principle of the climbing cone is to fix the embedded parts in the concrete during the concrete pouring process.

[0004] In the existing technology, after the concrete is poured, the climbing cone is installed in the existing concrete, and the climbing cone needs to be disassembled after use. The application of climbing cones in large-span steel structures is quite troublesome. When a large number of climbing cones need to be pre-embedded in the building, the workload in the later stage is large. Summary of the Invention

[0030] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0031] Reference Figures 1-8 The fourth-generation residential building features a large-span steel frame and climbing cone integrated installation structure, which includes multiple steel pipes 1 arranged in a row. The upper and lower steel pipes 1 are connected together by a first steel bar 2 and a second steel bar 3. The first steel bar 2 and the second steel bar 3 are installed together in a cross pattern. The connection point of the first steel bar 2 and the second steel bar 3 forms an intersection point. A first connecting steel rod 4 and a second connecting steel rod 5 are set at the intersection point. The first connecting steel rod 4 and the second connecting steel rod 5 are respectively set on both sides of the first steel bar 2.

[0032] A second connecting shaft 11 is inserted into the second connecting steel rod 5, and a first connecting shaft 10 is inserted into the first connecting steel rod 4. The upper ends of the second connecting shaft 11 and the first connecting shaft 10 are connected together by the connecting frame 9.

[0033] The lower end of the second connecting shaft 11 is provided with a mounting ring 12, and an extension shaft 14 is slidably mounted on the mounting ring 12. A climbing cone 6 is slidably mounted on one side of the extension shaft 14. The climbing cone 6 includes a tapered sleeve 16 and a threaded rod 17 threadedly inserted into the tapered sleeve 16.

[0034] An L-shaped shaft 15 is also connected between the second connecting shaft 11 and the first connecting shaft 10. The connecting frame 9 is used to adjust the horizontal distance between the first connecting steel rod 4 and the second connecting steel rod 5, and the L-shaped shaft 15 is used to adjust the vertical distance between the first connecting steel rod 4 and the second connecting steel rod 5.

[0035] Right-angle connecting blocks 7 are installed at the intersection points of the intersecting second reinforcing bars 3 and first reinforcing bars 2. The side of the right-angle connecting block 7 that is in contact with the first reinforcing bar 2 is fixed with screws, and the side of the right-angle connecting block 7 that is in contact with the second reinforcing bar 3 is also fixed with screws. Multiple first mounting sleeves 8 are fitted onto the steel pipe 1, and one side of each first mounting sleeve 8 is fixed to the second reinforcing bar 3 with screws. The intersecting first reinforcing bars 2 and second reinforcing bars 3 are installed and fixed at their intersection points using right-angle connecting blocks 7. The right-angle connecting blocks 7 have an L-shaped structure. After the first reinforcing bars 2 and 3 are installed together, they are fixed using the right-angle connecting blocks 7. The steel pipe 1 has a cylindrical structure; the first mounting sleeves 8 are fitted onto its surface, and then the first mounting sleeves 8 are fixedly connected to the adjacent second reinforcing bars 3.

[0036] The upper end of the second connecting shaft 11 is provided with a protrusion 20. One end of the connecting frame 9 is sleeved on the protrusion 20. A threaded sleeve 21 is threaded onto the protrusion 20. A connecting groove is provided on the connecting frame 9. The upper end of the first connecting shaft 10 is slidably engaged in the connecting groove. The upper end of the first connecting shaft 10 is engaged with one side of the connecting frame 9 by an elastic clip 19. The first connecting shaft 10 is engaged with one side of the connecting frame 9 by the elastic clip 19, thereby determining the positional relationship between the first connecting shaft 10 and the connecting frame 9. The other end of the connecting frame 9 is sleeved on the upper end of the second connecting shaft 11, and then the connecting frame 9 is fixed by the threaded sleeve 21.

[0037] The upper end of the first connecting shaft 10 is provided with a slot, and one side of the connecting frame 9 is provided with a toothed groove 23. One end of the elastic card 19 is inserted into the slot, and the other end of the elastic card 19 engages with the toothed groove 23. The slot is cross-shaped. One end of the elastic card 19 is fixed by snapping into the slot, and the other end is fixed by engaging with the toothed groove 23, thereby fixing the position of the first connecting shaft 10 relative to the connecting frame 9.

[0038] The second connecting shaft 11 has a second mounting groove 22, and the first connecting shaft 10 has a first mounting groove 24. One end of the L-shaped shaft 15 is connected to an arc-shaped sleeve 33 via a plug 35. Both the upper and lower ends of the arc-shaped sleeve 33 are provided with mounting shafts 34. The mounting shafts 34 are fitted onto the second connecting steel rod 5 from one side, and the upper and lower mounting shafts 34 are inserted into the second mounting groove 22. The other end of the L-shaped shaft 15 is provided with an I-shaped block 32, which is inserted into the first mounting groove 24 from top to bottom. The arc-shaped sleeve 33 has multiple holes, and the plug 35 is inserted into the holes. The vertical distance between the first connecting steel rod 4 and the second connecting steel rod 5 can be controlled by the L-shaped shaft 15. The arc-shaped sleeve 33 is inserted into the second connecting steel rod 5 from one side. The arc-shaped sleeve 33 is relatively fixed to the second connecting steel rod 5 by the insertion shaft 34. The insertion block 35 at one end of the L-shaped shaft 15 is inserted into different hole positions. The I-shaped block 32 at one end of the L-shaped shaft 15 is stuck at the lower end of the first connecting steel rod 4. The first connecting steel rod 4 and the second connecting steel rod 5 are located on both sides of the first reinforcing bar 2 and the second reinforcing bar 3, respectively. One side of the first connecting steel rod 4 is restricted by the first reinforcing bar 2 and the second reinforcing bar 3, and the other side is restricted by the I-shaped block 32. Therefore, the vertical distance between the first connecting steel rod 4 and the second connecting steel rod 5 is limited by the L-shaped shaft 15, the arc-shaped sleeve 33 and the I-shaped block 32.

[0039] One end of the extension shaft 14 is provided with a collar 13, which is slidably sleeved on the mounting ring 12. The end of the collar 13 away from the extension shaft 14 is slidably engaged with the inner wall of the mounting ring 12, and the end away from the extension shaft 14 is provided with a stop block 29. A retaining shaft 30 is fixedly connected to the stop block 29, and a retaining block 31 is sleeved on the retaining shaft 30. The mounting ring 12 is engaged between the retaining block 31 and the stop block 29. One side of the retaining shaft 30 is fixed with a nut. The orientation angle of the tapered sleeve 16 is determined according to the architectural design. The extension shaft 14 is rotated around the mounting ring 12 to the corresponding angle position through the collar 13. The other end of the collar 13 is clamped and fixed by the retaining block 31 and the stop block 29. The threaded nut is used for clamping and fixing. The clamping by the retaining block 31 only needs to keep the angle of the tapered sleeve 16 stable. The extension shaft 14 can rotate along the mounting ring 12, so that the angle can be adjusted in real time as needed.

[0040] A locking block 25 is provided on one side of the tapered sleeve 16. A sliding groove is provided on the extension shaft 14, and the locking block 25 is slidably installed in the sliding groove. A fastening sleeve 26 is sleeved on the extension shaft 14. The fastening sleeve 26 has an opening, and an insert shaft 27 is inserted into the opening. The insert shaft 27 is fixed to the fastening sleeve 26 by a nut. The tapered sleeve 16 can move along the sliding groove via the locking block 25, and then be locked by the fastening sleeve 26. By tightening the fastening sleeve 26, it is compressed along the sliding groove, thereby fixing the relative position of the locking block 25. The position of the tapered sleeve 16 relative to the extension shaft 14 can be changed, and the position of the extended tapered sleeve 16 can be adapted to the needs of different architectural designs.

[0041] A connecting block 18 is fixedly installed at one end of the threaded rod 17, and the connecting block 18 has multiple mounting holes. The threaded rod 17 is connected to other external structures through the connecting block 18.

[0042] A second mounting sleeve 28 is also fitted onto the second connecting steel rod 5, and the second mounting sleeve 28 is fixedly connected to the second reinforcing bar 3 by screws. The first connecting steel rod 4 and the second connecting steel rod 5 are connected together by the first connecting shaft 10 and the second connecting shaft 11. The second connecting steel rod 5 is fixedly connected to the adjacent second reinforcing bar 3 by the second mounting sleeve 28, ensuring the stability of the positions of the first connecting steel rod 4 and the second connecting steel rod 5 relative to the first reinforcing bar 2 and the second reinforcing bar 3.

[0043] When constructing a large-span building, the first step is to erect large-span steel sections. Based on the building structure, the first reinforcing bar 2 and the second reinforcing bar 3 are installed. The first reinforcing bar 2 is erected facing one direction, and the second reinforcing bar 3 is erected facing the other direction. The first reinforcing bar 2 and the second reinforcing bar 3 are intersected and intersected, forming intersection points. Right-angle connecting blocks 7 are used to fix the sections at these intersection points. The two sides of the right-angle connecting blocks 7 are fixed to the first reinforcing bar 2 and the second reinforcing bar 3 respectively using screws. Then, steel pipes 1 are installed on one side of multiple intersection points. Each steel pipe 1 is fixed to the second reinforcing bar 3 using a first mounting sleeve 8. Thus, the steel pipes 1 connect the arranged first reinforcing bars 2 and the second reinforcing bars 3 together, forming a large-span integral structure.

[0044] According to the requirements of the long-span structure, the first connecting steel rod 4 and the second connecting steel rod 5 are installed at corresponding positions. The first connecting steel rod 4 and the second connecting steel rod 5 are respectively placed on both sides of the intersection point. First, the second connecting steel rod 5 is fixedly connected to the adjacent second reinforcing bar 3 through the collar 13. The second connecting shaft 11 is inserted into the corresponding position on the second connecting steel rod 5. The first connecting steel rod 4 is inserted into the corresponding position on the first connecting steel rod 4. Multiple through slots for inserting the first connecting shaft 10 and the second connecting shaft 11 are opened on the second connecting steel rod 5 and the first connecting steel rod 4. The upper ends of the first connecting shaft 10 and the second connecting shaft 11 are connected together by the connecting frame 9. The lower ends of the first connecting shaft 10 and the second connecting shaft 11 are connected together. The two connecting shafts are connected together by an L-shaped shaft 15. The lower end of the second connecting shaft 11 is slidably connected to an extension shaft 14 via an mounting ring 12. A tapered sleeve 16 and a threaded rod 17 are provided on one side of the extension shaft 14. The tapered sleeve 16 can move relative to the extension shaft 14 via a locking block 25 to change its extended position. When cement is poured, the end of the tapered sleeve 16 and the threaded rod 17 will be exposed and not covered by cement. In the later stage of construction, the climbing cone 6 can be used directly through the connecting block 18 to build other building structures. The angle of the extension shaft 14 can be changed. The extension shaft 14 can rotate around the mounting ring 12 via a collar 13. The angle of the collar 13 is clamped and fixed by a stop block 29 and a locking block 31.

[0045] This structure integrates the climbing cone 6 with the overall steel structure. While the steel structure is being built, the corresponding climbing cone 6 is directly installed at the corresponding position, which effectively reduces the subsequent drilling and installation process, improves work efficiency, and makes the climbing cone 6 a unified whole with the overall structure, ensuring that the position of the climbing cone 6 itself is very stable.

[0046] The spacing between the first connecting steel rod 4 and the second connecting steel rod 5 can be adjusted according to the degree of intersection of the first reinforcing bar 2 and the second reinforcing bar 3. First, the second connecting shaft 11 is inserted into the second connecting steel rod 5, and then the first connecting shaft 10 is inserted into the first connecting steel rod 4. One end of the connecting frame 9 at the upper end of the first connecting shaft 10 is fitted onto the protrusion 20. The connecting frame 9 is fixed to the protrusion 20 by the threaded sleeve 21. The position of the upper end of the first connecting shaft 10 relative to the connecting frame 9 is adjusted. An elastic card 19 is inserted into the upper end of the first connecting shaft 10. The other end of the elastic card 19 is fastened to the toothed groove 23 on one side of the connecting frame 9. Then the position of the first connecting shaft 10 relative to the connecting frame 9 is fixed.

[0047] Then, the arc-shaped sleeve 33 is inserted from one side of the second connecting steel rod 5. The arc-shaped sleeve 33 is respectively secured to the upper and lower sides of the second connecting steel rod 5 by two upper and lower mounting shafts 34. One end of the L-shaped shaft 15 is fastened to the hole by the insert block 35, and the other end is secured to the first connecting shaft 10 by the I-shaped block 32. The upper side of the first connecting steel rod 4 is in contact with the first reinforcing bar 2 and the second reinforcing bar 3, and the lower side is restricted by the I-shaped block 32, thereby effectively restricting the position of the first connecting steel rod 4 and the second connecting steel rod 5. By restricting the position and angle of the first connecting steel rod 4 and the second connecting steel rod 5, the angular position stability of the first reinforcing bar 2 and the second reinforcing bar 3 can also be strengthened, thereby strengthening the stability of the steel structure when installing the climbing cone 6.

[0048] The above description is only a preferred embodiment of the present invention. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of the present invention, and these improvements and modifications should also be considered within the scope of protection of the present invention.
