Description

Technical Field

[0001] This invention belongs to the field of building construction technology, specifically a structure and method for installing inclined outer columns of a high-rise frame core tube. Background Technology

[0002] Existing core tube structure buildings generally consist of an internal core tube structure and an outer frame distributed on the outside, with the outer frame and core tube connected by inclined outer columns. In actual assembly, there are often limited operating spaces, such as the inclined outer columns between the core tube and the outer frame. Using traditional high-strength threads (e.g., patent documents CN218061588U, CN101906849A, etc.) would make the assembly operation complex, inefficient, and involve high-altitude work, posing a safety risk. Summary of the Invention

[0003] The technical problem to be solved by this invention is: how to efficiently complete the installation of inclined external columns within a limited operating space.

[0004] To solve the above-mentioned technical problems, the inventors, through practice and summarization, derived the technical solution of this invention, which adopts the following technical solution:

[0005] A high-rise frame core tube inclined outer column mounting structure includes:

[0006] The core tube has end embedded parts installed on its outer wall;

[0007] The outer frame is located outside the core tube, and end connectors are provided on the outer frame.

[0008] Inclined outer column, which is installed between the end embedded part and the end connector;

[0009] Box 1, which is fixed to the end of the inclined outer column;

[0010] Box 2 is fixed to the end connector and the end embedded part;

[0011] A threaded rod is inserted into box one and box two.

[0012] Clamping components are installed on housing one and housing two to clamp and lock the threaded rod.

[0013] In the aforementioned scheme, the first box and the second box are provided with corresponding insertion openings;

[0014] The insertion port is divided into an insertion part and a locking part. The two sets of insertion ports are symmetrically distributed and the insertion parts are located on the same side that are close to each other.

[0015] In the aforementioned scheme, the clamping component includes clamping flaps, squeezing components, and spring components. Multiple clamping flaps are provided and distributed on the outside of the threaded rod and located inside the locking part on the side near the insertion part. Threaded portions are distributed on the inner wall of the clamping flaps to clamp the threaded rod from the outside in. The squeezing components are fitted on the outside of the threaded rod and located inside the locking part on the side away from the insertion part. The spring components are distributed on the outside of the threaded rod.

[0016] In the aforementioned scheme, the locking part has a tapered structure on the side near the interpenetrating part. The tapered structure is used to clamp the petals inward and squeeze the threaded rod.

[0017] The inner wall of the clamping petal is provided with a constraint groove, and an elastic expansion member is installed in the constraint groove. The elastic expansion member has a C-shaped structure and is used to abut the clamping petal against the locking part.

[0018] In the aforementioned scheme, a push-restraint plate is distributed between the spring member and the clamping petal. The push-restraint plate is located at the end of the clamping petal near the spring member, and a restraint ring is provided at the end near the clamping petal. The restraint ring and the push-restraint plate are connected by a spring. A locking groove is distributed on the side of the clamping petal near the push-restraint plate. The locking groove and the restraint ring are positioned correspondingly and are mutually compatible.

[0019] In the aforementioned scheme, guide ears are distributed on the outer side of the extrusion member, and guide arc grooves are distributed on the side wall of the locking part port. The guide arc grooves and guide ears are slidably engaged, and a horizontal locking semi-annular groove is distributed at the root of the guide arc groove.

[0020] An elastic constraint body is provided on the side of the guide ear opposite to the spring component. The elastic constraint body includes a mounting groove, in which an elastic body, a constraint ball, and a set screw are installed. The set screw pushes the constraint ball to the side opposite to the spring component by squeezing the elastic body. A locking groove is distributed on the side of the horizontal locking semi-annular groove away from the spring component, which is used to constrain and limit the separation of the extrusion component and the locking part.

[0021] In the aforementioned scheme, dovetail grooves are distributed on opposite sides of box one and box two, and dovetail inserts are inserted into the dovetail grooves. The dovetail inserts are used to connect box one and box two.

[0022] In the aforementioned scheme, the inclined outer column includes a central frame and four inclined columns. The four free ends of the central frame are connected to the inclined columns through a first box, a second box, a threaded rod, and a clamping member.

[0023] In the aforementioned scheme, the inclined outer columns are connected by turnbuckles.

[0024] A construction method for an inclined external column installation structure of a high-rise frame core tube includes:

[0025] Step 1, Installation of end embedded parts

[0026] The second box body is fixed by welding the end embedded parts, and the end embedded parts are pre-embedded on the steel cage of the core tube during construction.

[0027] Step 2, Installation of end connectors

[0028] Weld the end connector to fix the second box body, and install the lower flat seat of the end connector on the outer frame with high-strength bolts;

[0029] Step 3, Installation of inclined outer columns

[0030] Box 1 is welded and fixed on the inclined outer column. The inclined column is hoisted to the predetermined position and the positions of Box 1 and Box 2 are aligned. A threaded rod is inserted into the insertion part of Box 1 and Box 2. A clamping petal, a pushing constraint piece, and a spring are installed on the outside of the threaded rod and inside the locking part. The extrusion piece is installed in the locking part and compresses the spring. The spring pushes the constraint piece closer to the insertion part and clamps it on the outside of the threaded rod. When it is clamped, the constraint ring and the locking groove are matched and constrain the clamping petal to keep the ring structure locked.

[0031] When the guide ear of the extruded part enters the guide arc groove and then the horizontal locking semi-annular groove, the elastic constraint body and the locking groove adapt to ensure structural stability.

[0032] After the inclined columns are installed, the ends of the inclined columns closest to the central frame are pulled and restrained together using turnbuckles.

[0033] The central frame is hoisted to the area between the inclined columns, and the assembly is completed using clamping parts, threaded rods, box one, and box two.

[0034] After all assembly work is completed, dovetail inserts are used to connect box one and box two to avoid the risk of shearing the threaded rod.

[0035] Compared with the prior art, the present invention has the following beneficial effects:

[0036] The structure is assembled using box one and box two in conjunction with threaded rods and clamping components. The extrusion component compresses the spring component, which in turn compresses and pushes the constraint plate. A constraint ring fits into the constraint groove, locking the clamping plate into a ring structure that is locked to the outside of the threaded rod. This locking method prevents the threads from easily loosening and enhances structural stability. A dovetail insert is also added between box one and box two to avoid relative torsion and shear risks, ensuring long-term structural stability. Attached Figure Description

Therefore, they should not be construed as limitations on this invention.

[0047] Example 1

[0048] A high-rise frame core tube inclined outer column mounting structure includes:

[0049] Core tube 10, with end embedded parts 11 installed on the outer wall of core tube 10;

[0050] The outer frame 20 is distributed on the outside of the core tube 10, and the outer frame 20 is provided with end connectors 21.

[0051] An inclined outer column 30 is installed between the end embedded part 11 and the end connector 21.

[0052] Box 40 is fixed to the end of the inclined outer column 30;

[0053] Box body 2 50, which is fixed on end connector 21 and end embedded part 11;

[0054] Threaded rod 60, threaded rod 60 is inserted into box body 40 and box body 50;

[0055] Clamping component 70 is installed on housing 1 40 and housing 2 50 to clamp and lock the threaded rod 60.

[0056] The first box 40 and the second box 50 are provided with corresponding insertion openings;

[0057] The insertion port is divided into an insertion part 41 and a locking part 42. The two sets of insertion ports are symmetrically distributed, and the insertion parts 41 are located on the side closest to each other. The insertion part 41 is internally distributed with elastic rubber parts, which are used to restrain the threaded rod 60 to prevent it from accidentally falling off before assembly or from shifting its position during assembly.

[0058] The clamping member 70 includes a clamping flap 71, a squeezing member 72, and a spring member 73. Multiple clamping flaps 71 are provided and distributed on the outside of the threaded rod 60 and located inside the locking part 42 on the side close to the insertion part 41. Threaded portions are distributed on the inner wall of the clamping flaps 71 to clamp the threaded rod 60 from the outside in. The squeezing member 72 is fitted on the outside of the threaded rod 60 and located inside the locking part 42 on the side away from the insertion part 41. The spring member 73 is distributed on the outside of the threaded rod 60.

[0059] Among them, such as Figure 3 , 4 As shown in Figure 8, the locking part 42 has a tapered structure on the side near the insertion part 41. The tapered structure is used to hold the petals 71 inward and squeeze the threaded rod 60.

[0060] The inner wall of the clamping petal 71 is provided with a constraint groove 74, and an elastic expansion member 75 is installed in the constraint groove 74. The elastic expansion member 75 has a C-shaped structure and is used to abut the clamping petal 71 against the locking part 42.

[0061] Among them, such as Figure 5 As shown, guide ears 78 are distributed on the outer side of the extrusion member 72, and guide arc grooves 79 are distributed on the side wall of the locking part 42 port position. The guide arc grooves 79 and guide ears 78 are slidably engaged, and a horizontal locking semi-annular groove 710 is distributed at the root of the guide arc grooves 79.

[0062] An elastic constraint body 712 is provided on the side of the guide ear 78 opposite to the spring member 73, such as Figure 6As shown, the elastic constraint body 712 includes a mounting groove, in which an elastic body, a constraint ball, and a set screw are installed. The set screw pushes the constraint ball toward the side opposite to the spring member 73 by squeezing the elastic body. The root of the horizontal locking semi-annular groove 710 has locking grooves distributed on the side away from the spring member 73, which are used to constrain and limit the separation of the extrusion member 72 and the locking part 42.

[0063] Through the inward pressing action of the extruder 72, the spring 73 is compressed and directly acts on the clamping flap 71. After acting on the tapered structure, it will press the elastic expansion member 75 inward to finally form a ring-shaped clamping cone sleeve. The guide ear 78 will move inward along the guide arc groove 79. After moving to the final position, it will lock the position of the horizontal locking half-ring groove 710. The clamping cone sleeve will lock the threaded rod 60 to achieve the locking and fixing effect. At this time, the extruder 72 will rotate a certain angle relative to the box until the elastic constraint member 711 and the locking groove are constrained and fixed.

[0064] Example 2

[0065] In the installation structure, such as Figure 3 , 4 As shown in Figure 5, a push-restraint piece 76 is distributed between the spring member 73 and the clamping petal 71. The push-restraint piece 76 is arranged at one end of the clamping petal 71 near the spring member 73, and a restraint ring 77 is arranged at the end near the clamping petal 71. The restraint ring 77 and the push-restraint piece 76 are connected by a spring. A locking groove 711 is distributed on the side of the clamping petal 71 near the push-restraint piece 76. The locking groove 711 and the restraint ring 77 are positioned correspondingly and are mutually compatible.

[0066] In practical implementation, the compression action of the spring 73 alone cannot effectively ensure that the clamping cone ring sleeve can maintain a locked state for a long time. Furthermore, the clamping flap 71 will have a certain radial displacement relative to the threaded rod 60. This displacement can easily cause the spring 73 to twist and deform, or even jam. Since the threaded rod 60 is locked inside the housing, construction personnel cannot effectively ensure that the threaded rod 60 is in a locked state. Therefore, a push-restraint piece 76 is added to effectively lock the threaded rod 60. When the extrusion piece 72 is assembled to the corresponding position, the restraint ring 77 and the locking groove 711 will be effectively restrained and locked, thus ensuring structural stability. To avoid jamming between the restraint ring 77 and the clamping flap 71, a spring is used to achieve flexible assembly, allowing it to be immediately locked into the locking groove 711 after clamping the threaded rod 60.

[0067] Example 3

[0068] In the installation structure, such as Figure 1As shown, dovetail grooves 43 are distributed on opposite sides of both box body 40 and box body 50. Dovetail inserts 44 are inserted into the dovetail grooves 43, and the dovetail inserts 44 are used to connect box body 40 and box body 50. The dovetail grooves 43 are distributed on the top side and non-bottom side of box body 40 and box body 50. In order to ensure that the dovetail inserts 44 and dovetail grooves 43 are separated, permanent magnets can be arranged inside the dovetail grooves 43. In order to reduce the negative impact of torque shear, the dovetail inserts 44 are used to achieve long-term structural stability.

[0069] Example 4

[0070] In the installation structure, such as Figure 1 As shown, the inclined outer column 30 includes a central frame 31 and four inclined columns 32. The four free ends of the central frame 31 are connected to the inclined columns 32 through a first box 40, a second box 50, a threaded rod 60 and a clamping member 70.

[0071] The inclined outer columns 30 are connected by turnbuckles 33, which serve as temporary support points to ensure the structural stability of the inclined columns 32 and prevent positional shifts before the central frame 31 is assembled.

[0072] like Figures 1 to 8 As shown, a construction method for an inclined outer column installation structure of a high-rise frame core tube includes:

[0073] Step 1, Installation of end embedded parts 11

[0074] The box body 2 50 is welded and fixed by the end embedded part 11, and the end embedded part 11 is pre-embedded on the steel cage of the core tube 10 during construction.

[0075] Step 2, Install end connector 21

[0076] Weld the end connector 21 to fix the box body 2 50, and install the lower flat seat of the end connector 21 onto the outer frame with high-strength bolts;

[0077] Step 3, Install the inclined outer column 30

[0078] Box 1 40 is welded and fixed on the inclined outer column 30. The inclined column 32 is hoisted to the predetermined position and the positions of box 1 40 and box 2 50 are aligned. The threaded rod 60 is inserted into the insertion part 41 of box 1 40 and box 2 50. The clamping petal 71, the pushing constraint piece 76 and the spring 73 are installed on the outside of the threaded rod 60 and inside the locking part 42. The extrusion piece 72 is installed in the locking part 42 and compresses the spring 73. The spring 73 pushes the constraint piece 76 to gradually approach the insertion part 41 and clamps it on the outside of the threaded rod 60. When it is clamped, the constraint ring 77 and the locking groove 711 are adapted to and constrain the clamping petal 71 to keep the ring structure locked.

[0079] When the guide ear 78 of the extrusion part 72 enters the guide arc groove 79 and then enters the horizontal locking semi-annular groove 710, the elastic constraint body 712 and the locking groove are matched to ensure structural stability.

[0080] After the inclined column 32 is installed, the ends of the inclined column 32 near the center frame 31 are pulled and constrained by turnbuckles 33.

[0081] The central frame 31 is hoisted to the area between the inclined columns 32, and the assembly is completed using clamping parts 70, threaded rods 60, box body one 40, and box body two 50.

[0082] After all assembly work is completed, dovetail inserts 44 are used to connect box 1 40 and box 2 50 to avoid the risk of shearing of threaded rod 60.

[0083] The above description is merely a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. The substitutions may be replacements of some structures, devices, or method steps, or they may be complete technical solutions. Equivalent substitutions or modifications made to the technical solutions and inventive concepts of the present invention should all be covered within the scope of protection of the present invention.
