Description

Technical Field

[0001] The present invention relates to the technical field of building structures, and in particular to a hanger, a steel structure hanging connection device and a double-layer steel structure building. Background Art

[0002] In large-scale steel lattice shell structure combined with steel arch beam structure construction projects, the inner steel lattice shell structure is suspended at the bottom of the outer steel arch beam structure to form a structural system with common loads.

[0003] There is a spatial structure ceiling system for earthquake resistance, which includes a roof connection structure, a hanger structure and a keel connection structure. The roof connection structure is used to be fixedly connected to the roof, the hanger structure is hoisted on the top of the roof connection structure, and a spring is arranged between the hanger structure and the roof connection structure. When the hanger structure is subjected to increased gravity, the spring is compressed and deformed to produce an earthquake-resistant effect; the bottom of the hanger structure is a hinge ball, a ball socket is provided on the keel connection structure, and a pressure plate is provided on the keel connection structure to ensure that the hinge ball is located in the ball socket, and the bolts fix the pressure plate to the keel connection structure.

[0004] Multiple keel connection structures connect to each other to form a ceiling network. This network is suspended by multiple hanger rods, and decorative panels are fixed to the underside of the network. Existing spatial structure ceiling systems are non-structural components, outside the building structure. They utilize springs and ball joints to provide seismic protection for the suspended network.

[0005] However, for large-scale steel lattice shell structures combined with steel arch beam structures, the inner steel lattice shell structure is fixedly connected to the building site rather than being suspended. The purpose of the hanging connection device set between the inner steel lattice shell structure and the outer steel arch beam structure is not simply to deal with seismic forces. More importantly, the hanging connection device needs to deal with the complex multi-dimensional deformation between the two steel structure layers with different stiffnesses caused by external factors (such as temperature and seismic forces). Under multi-dimensional deformation, the force directions of each hanging point are different and the force is large. Therefore, the hanging connection device set between the inner steel lattice shell structure and the outer steel arch beam structure serves as a key load-bearing structural component in the building structure.

[0006] However, the existing spatial structure ceiling system can only produce seismic resistance for indoor ceiling objects in a suspended state, and cannot be applied as a key load-bearing structural component to large-scale steel gridshell structure combined with steel arch beam structure construction projects. Summary of the Invention

[0007] The first object of the present invention is to provide a boom that can effectively cope with complex multi-dimensional deformations.

[0008] The second object of the present invention is to provide a steel structure hanging connection device that can effectively cope with complex multi-dimensional deformation.

[0009] The third object of the present invention is to provide a double-layer steel structure building that can effectively cope with complex multi-dimensional deformation.

[0010] The first purpose of the present invention provides a hanger, whose bottom end is a hinge ball; the hanger includes a first extension structure and a second extension structure movably connected along its extension direction, and the hinge ball is located at the end of the second extension structure; the hanger also includes a first deformation module and a second deformation module; the first extension structure has a first abutment portion and a second abutment portion set oppositely; the second extension structure has a third abutment portion and a fourth abutment portion set oppositely; in the extension direction, the first deformation module is arranged between the first abutment portion and the third abutment portion, and the second deformation module is arranged between the second abutment portion and the fourth abutment portion; when the hanger is in a tension state, the first deformation module abuts between the first abutment portion and the third abutment portion; when the hanger is in a compression state, the second deformation module abuts between the second abutment portion and the fourth abutment portion; the length of the hanger in the compression state is less than the length of the hanger in the tension state.

[0011] It can be seen from the above scheme that the first deformation module and the second deformation module with opposite force directions are arranged in the hanger, so that the hanger has the ability to resist compression and tension. In addition, with the cooperation of the hinge ball, the hanging point can cope with pressure or tension in different directions and sizes caused by complex multi-dimensional deformation. Therefore, it can be well set as a key load-bearing structural component between the inner steel grid shell structure and the outer steel arch beam structure.

[0012] A further solution is that the first deformation module includes a disc spring, and / or the second deformation module includes a disc spring.

[0013] As can be seen from the above, the hanger as a load-bearing structural member needs to resist or minimize deformation. If a spring is used, there will be problems of large deformation and low compressive strength. The disc spring has better compressive strength and smaller deformation, and is more suitable as a deformation component to be set in the hanger.

[0014] A further solution is that the number of disc springs included in the first deformation module is greater than the number of disc springs included in the second deformation module.

[0015] As can be seen from the above, under the action of gravity, the deformation of the suspension rod in the retracted state is larger, so the first deformation module includes more disc springs to have a more suitable deformation.

[0016] A further solution is that the first extension structure includes a cylinder and an annular member, the annular member is fixed on the cylinder, and the first abutment portion and the second abutment portion are respectively located at the axial ends of the annular member; the second extension structure includes a rod body and a sleeve member, the sleeve member is sleeved in the extended middle part of the rod body, the hinge ball is fixed to the first extended end portion of the rod body, the second extended end portion of the rod body is provided with a baffle, the third abutment portion is located on the baffle, and the fourth abutment portion is located on the sleeve member; the rod body can movably pass through the annular member and extend into the cylinder, and the annular member is located between the sleeve member and the baffle.

[0017] As can be seen from the above, this setting is conducive to the processing and assembly of the boom, ensuring the structural strength of the boom. At the same time, the first deformation module and the second deformation module can be placed in the cylinder as internal components, thereby further strengthening the structural protection of the boom and extending its service life.

[0018] A further solution is that the inner periphery of the sleeve is provided with a first internal thread, the outer periphery of the rod body is provided with a first external thread, and the first internal thread cooperates with the first external thread.

[0019] Another further solution is that the outer circumference of the annular member is provided with a second external thread, the inner circumference of the cylinder is provided with a second internal thread, and the second external thread cooperates with the second internal thread.

[0020] As can be seen from the above, it is relatively easy to process threads on the circumferential surface, and this arrangement can further facilitate the processing and assembly of various components.

[0021] A further solution is that an annular step is provided at the axial end of the cylinder, and the annular member is fixed on the annular step.

[0022] As can be seen from the above, the annular step can effectively limit the annular member to a fixed position in the axial direction, thereby improving the stability of the boom.

[0023] The second purpose of the present invention provides a steel structure hanging connection device including a hanger and a hanging point connection structure, the hanging point connection structure including a beam connection seat and a locking piece, the locking piece is installed on the beam connection seat, and a ball socket is formed between the locking piece and the beam connection seat; the hanger adopts the above-mentioned hanger, the hinge ball is located in the ball socket, and the hinge ball supports the locking piece; the locking piece can rotate and reach a locked position, and when the locking piece is in the locked position, the locking piece supports the beam connection seat.

[0024] As can be seen from the above scheme, the improvement of the hanger enables the hanging point to cope with pressure or tension in different directions and sizes caused by complex multi-dimensional deformation. In addition, in the existing spatial structure ceiling system, the pressure plate is supported by the hanger. Since the existing spatial structure ceiling system is not a structural component, the keel connection structure and the ceiling structure network composed of the keels are supported by bolts connected between the pressure plate and the keel connection structure. However, bolts are not sufficient to cope with the force on the hanging point in a double-layer steel structure building. Therefore, the present invention uses the locking member itself to support the beam body connection seat, increase the force surface, avoid stress concentration, and avoid irreparable structural damage such as breaking or crushing.

[0025] A further solution is that the locking piece is provided with at least two first bosses arranged along the circumferential direction and extending toward the outer periphery; the beam body connecting seat has a mounting recess for forming a ball socket, and the inner circumferential surface of the mounting recess is provided with at least two second bosses arranged along the circumferential direction and extending toward the inner periphery, and an mounting space is formed between the bottom surface of the mounting recess and the multiple second bosses; in the circumferential direction of the mounting recess, there is a gap between two adjacent second bosses to form a space entrance connected to the mounting space; the first boss can enter the mounting space from the space entrance and rotate to reach the locking position; when the locking piece is in the locking position, the first boss supports the second boss.

[0026] As can be seen from the above, this arrangement realizes a structure for quick disassembly and assembly. The locking piece is inserted and rotated to reach the locking position, and the hanger, locking piece and beam connecting seat can achieve support.

[0027] The third purpose of the present invention provides a double-layer steel structure building including an inner steel lattice shell structure, an outer steel arch beam structure and a steel structure hanging connection device arranged between the inner steel lattice shell structure and the outer steel arch beam structure, wherein the inner steel lattice shell structure includes multiple structural beams; the steel structure hanging connection device adopts the above-mentioned steel structure hanging connection device; the top of the first extension structure is connected to the outer steel arch beam structure; and the multiple structural beams are connected by a hanging point connection structure.

[0036] First embodiment of the steel structure hanging connection device

[0037] See also Figure 1 and Figure 2 The double-layer steel structure building of this embodiment includes an inner steel lattice shell structure 4, an outer steel arch beam structure 5, and a steel structure hanging connection device disposed between the inner steel lattice shell structure 4 and the outer steel arch beam structure 5. The inner steel lattice shell structure 4 includes multiple structural beams 41. The steel structure hanging connection device includes a hanger rod 1 and a hanging point connection structure 2. The hanging point connection structure 2 is connected between the multiple structural beams 41, and the hanger rod 1 is connected between the outer steel arch beam structure 5 and the hanging point connection structure 2.

[0038] The outer steel arch beam structure 5 includes multiple relatively large steel arch beams, the extended ends of which, i.e., the bottom ends on both sides, are fixed to the building site. The interior of the inner steel lattice shell structure 4 is the interior space of the building, and the bottom of the inner steel lattice shell structure 4 is also fixed to the building site. The outer steel arch beam structure 5 and the inner steel lattice shell structure 4 have different steel stiffnesses. After the steel structure hanging connection device is installed between the outer steel arch beam structure 5 and the inner steel lattice shell structure 4, the steel structure hanging connection device needs to cope with the complex multi-dimensional deformation between the two steel structure layers with different stiffnesses due to external factors (such as temperature and seismic force). Under multi-dimensional deformation, the force directions of each hanging point are different and the force is large.

[0039] See also Figure 2 The bottom end of the suspender rod 1 is a hinge ball 151. The suspension point connection structure 2 includes a beam connection seat 21 and a locking member 22. The beam connection seat 21 is used as a central member to connect with multiple structural beams 41 of the inner steel lattice shell structure 4. The locking member 22 is mounted on the suspender rod 1 and supported by the hinge ball 151. The locking member 22 is also fixedly mounted on the beam connection seat 21. A ball socket is formed between the locking member 22 and the beam connection seat 21. The hinge ball 151 is located in the ball socket. Figure 2 As shown, the locking member 22 is in the locking position, and the locking member 22 supports the beam body connecting seat 21. The suspension rod 1 has a swinging degree of freedom relative to the suspension point connection structure 2.

[0040] join Figures 3 to 5 The boom 1 includes a first extension structure 11 and a second extension structure 12 movably connected along its extension direction, and a first deformation module 31 and a second deformation module 32 arranged between the first extension structure 11 and the second extension structure 12. Figure 1 The top of the first extension structure 11 is connected to the outer steel arch beam structure 5 .

[0041] The first extension structure 11 includes a cylindrical body 13 and an annular member 14. The second extension structure 12 includes a rod body 15 and a sleeve member 16. The first deformation module 31 includes four disc springs, and the second deformation module 32 includes one disc spring. As a force-bearing structure, the suspension rod 1 needs to resist or minimize deformation. Using a coil spring results in large deformation and low compressive strength. Disc springs, however, offer greater compressive strength and reduced deformation, making them more suitable as deformation components within the suspension rod 1.

[0042] The annular member 14 is fixed to the cylinder 13. A second external thread 149 is provided on the outer circumference of the annular member 14. An annular step 131 is provided at the axial end of the cylinder 13. The cylinder 13 is provided with a second internal thread 139 on the inner circumference of the annular step 131. The annular member 14 is fixed to the annular step 131. The second external thread 149 cooperates with the second internal thread 139 to fix the annular member 14 to the inner circumference of the end of the cylinder 13. The axial ends of the annular member 14 are respectively provided with a first abutment portion 141 and a second abutment portion 142. Since the first abutment portion 141 and the second abutment portion 142 are respectively used to abut and cooperate with corresponding disc springs, the first abutment portion 141 and the second abutment portion 142 are both annular surfaces arranged obliquely to the axial direction.

[0043] The hinge ball 151 is located at the first extended end of the rod body 15. The second extended end of the rod body 15 is provided with a baffle 152, and the axial surface of the baffle 152 serves as the third abutment portion 153. A first external thread 159 is provided on the outer periphery of the extended middle portion of the rod body 15. The sleeve member 16 of this embodiment is a limiting component with a truncated cone-shaped outer profile. The inner periphery of the sleeve member 16 is provided with a first internal thread 169. The sleeve member 16 is sleeved onto the outside of the rod body 15, and the first internal thread 169 mates with the first external thread 159. The sleeve member 16 is provided with a stepped hole 168 at the end with the larger outer diameter. The stepped hole 168 forms a stepped surface, which serves as the fourth abutment portion 161.

[0044] The rod 15 passes through the annular member 14 and extends into the cylindrical body 13, and the rod 15 is movable along the extension direction. The annular member 14 is located between the sleeve member 16 and the baffle 152. The multiple disc springs of the first and second deforming modules 31 and 32 are also mounted on the rod 15. The first deforming module 31 is arranged between the first abutting portion 141 and the third abutting portion 153, and the second deforming module 32 is arranged between the second abutting portion 142 and the fourth abutting portion 161. This arrangement forms a boom 1 with telescopic capabilities, and the boom 1 can withstand large tension and pressure. When the boom 1 is in a tensile state, the boom 1 extends to a longer length, and the first deforming module 31 abuts between the first abutting portion 141 and the third abutting portion 153. When the boom 1 is in a compressive state, the boom 1 contracts to a shorter length, and the second deforming module 32 abuts between the second abutting portion 142 and the fourth abutting portion 161.

[0045] The hanger 1, which has a certain telescopic ability and good tensile and compressive resistance, is combined with a ball joint pair to enable the hanging point to cope with pressure or tension in different directions and sizes caused by complex multi-dimensional deformation. It can be well set as a key load-bearing structural component between the inner steel grid shell structure 4 and the outer steel arch beam structure 5.

[0046] See also Figure 2 、 Figure 6 and Figure 7 The locking member 22 is annular and has a central insertion hole 220. On the underside of the locking member 22, the outer periphery of the insertion hole 220 has an arcuate surface that forms a ball socket. The rod 15 is inserted into the insertion hole 220, and the locking member 22 is supported on the hinge ball 151. In addition to the annular body 221, the locking member 22 also has three first bosses 24 evenly arranged along the circumference and extending toward the outer periphery.

[0047] The lower surface of the first boss 24 serves as a first guiding slope 242, and the upper surface of the first boss 24 serves as a first bearing surface 242, perpendicular to the axial direction. Axially, a gap exists between the annular body 221 of the locking member 22 and the first boss 24, creating a space for accommodating the second boss 23. The annular body 221 is also provided with an axially extending bolt hole 222.

[0048] The beam connection seat 21 has a mounting recess 200 that is recessed from top to bottom and forms a ball socket. Three second bosses 23 are evenly spaced along the circumference of the mounting recess 200 and extend toward the inner circumference. The upper surface of each second boss 23 forms a second guide slope 231, and the lower surface of each second boss 23 forms a second supporting mating surface 233. Each second boss 23 is provided with a threaded hole 232 arranged along the axis. Along the circumference of the mounting recess 200, adjacent second bosses 23 are spaced apart to form a space entrance 201 that connects to the mounting space 202. The first boss 24 can enter the mounting space 202 from the space entrance 201 and rotate to a locked position. The bolt 25 then passes through the bolt hole 222 and engages with the threaded hole 232, completing the installation between the beam connection seat 21 and the locking member 22. When the locking member 22 is in the locked position, the first boss 24 supports the second boss 23, and the locking member 22 itself supports the beam connecting seat 21, thereby increasing the force-bearing surface and avoiding stress concentration on the bolts, thereby avoiding irreparable structural damage such as breaking or crushing.

[0049] Second embodiment of the steel structure hanging connection device

[0050] See also Figure 8 In this embodiment, the structure of the suspension rod is different from that of the first embodiment. The first extension structure 61 of the suspension rod includes a cylinder 611, a ring member 612 and a blocking member 613. The ring member 612 and the blocking member 613 are fixed on the cylinder 611, and the first abutting portion and the second abutting portion are respectively located on the ring member 612 and the blocking member 613.

[0051] The second extension structure 62 of the boom includes a rod body 620, a hinge ball 621 fixed to the first extension end of the rod body 620, a baffle 622 provided at the second extension end of the rod body 620, and a third abutting portion and a fourth abutting portion located at the axial ends of the baffle 622. The rod body 620 movably passes through the annular member 612, and the baffle 622 is located between the annular member 612 and the blocking member 613.

[0052] The first deformation module 631 is disposed between the annular member 612 and the blocking plate 622 , and the second deformation module 632 is disposed between the blocking plate 622 and the blocking member 613 .

[0053] This embodiment can also realize a suspension rod with telescopic ability and compression and tension resistance.

[0054] In other embodiments, the sleeve member has an outer contour other than a truncated cone, for example, the outer contour of the sleeve member is cylindrical.

[0055] Finally, it should be emphasized that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention.
