Description

Technical Field

[0001] The present invention relates to the technical field of earthquake resistance for spherical buildings, and specifically to an earthquake-resistant spherical grid structure for steel structure buildings. Background Art

[0002] Steel structure buildings use steel as the main building structure. Usually, various building components are made of steel such as profiled steel and steel plates, and the forms are steel beams, steel columns, steel trusses, etc. The connection methods of welds, bolts or rivets are used to assemble each component into a complete structural system. Spherical grids are often seen in buildings and are a new type of building structure. They use rod and tube structures to replace traditional concrete, which not only does not weaken the load-bearing capacity but also plays a novel and beautiful role. Since spherical grids are mostly used in gymnasiums, art galleries, etc., the protection requirements for people or items inside the grid are quite important. At the same time, because the installation workload is large, the ease of installation is also quite important.

[0003] The patent with the application number CN202220389136.6 provides an earthquake-resistant spherical grid structure for steel structure buildings, including a spherical grid frame body. The spherical grid frame body further includes a plurality of reinforcing rings a. The plurality of reinforcing rings a are circumferentially distributed and fixed to the inner side wall of the spherical grid frame body. A plurality of circumferentially distributed reinforcing rings b are fixed to the inner side wall of the spherical grid frame body. A plurality of circumferentially distributed grooves are formed in one side wall of the spherical grid frame body. The solution provided by the above-mentioned invention patent application is to install the load-bearing column and the spherical grid frame body through the installation component to achieve fast and stable installation of the load-bearing column, which is suitable for large-area laying projects, so that the load-bearing column can evenly and well bear the pressure exerted by the spherical grid frame body, ensuring reliable support of the load-bearing column for the spherical grid frame body. The above patent only uses simple buffer springs to improve the earthquake resistance performance of the overall device. However, in an earthquake, it is impossible to avoid damage to the structure caused by vibration by relying on shock-absorbing springs. The spherical grid frame body lacks support and will still deform, affecting the stability of the building structure. Summary of the Invention

[0004] The purpose of the present invention is to provide an earthquake-resistant spherical grid structure for steel structure buildings to solve the problems raised in the above background art.

[0005] To solve the above technical problems, the technical solution of the present invention is: a seismic spherical grid structure for steel structure buildings, including a top seat and a base arranged below the top seat for providing support force. A plurality of bent plates are arranged outside the top seat, and a plurality of sets of strut mechanisms for supporting the bent plates are arranged outside the base. The upper end of the base is fixedly connected with a plurality of U-shaped frames for locking the strut mechanisms. The U-shaped frames are annularly arranged around the axis of the base. Through holes are formed in the U-shaped frames. The upper end of the base is fixedly connected with a main support rod, and the upper end of the main support rod is fixedly connected with a connecting seat. A plurality of rotating grooves corresponding to the strut mechanisms are formed outside the connecting seat. The strut mechanism includes a secondary support rod rotatably connected in the rotating groove. A sliding groove is formed at the lower end of the secondary support rod, and the sliding groove corresponds to the through hole. A lock rod assembly for locking the secondary support rod on the U-shaped frame is arranged in the sliding groove.

[0006] Preferably, a placement cavity is formed on one side of the secondary support rod, and a lock hole is formed on the inner wall of the placement cavity. A rotating support rod is arranged in the placement cavity, and the rotating support rod is rotatably connected to the lower part of the inner wall of the placement cavity. An electric plug lock corresponding to the lock hole is fixedly arranged in the rotating support rod, and a locking groove is formed at the other end of the rotating support rod.

[0007] Preferably, the strut mechanism further includes a locking component corresponding to one end of the rotating support rod arranged on the ground. The locking component includes a fixed stop block fixedly arranged on the ground. A groove corresponding to the rotating support rod is formed on the fixed stop block, and a through groove is formed in the groove.

[0008] Preferably, through grooves are formed on both sides of the groove in the fixed stop block. Connecting blocks are fixedly connected to both sides of the fixed stop block. Second springs are respectively fixedly connected to the inner parts of the two connecting blocks. The other ends of the second springs are fixedly connected to a sliding plate. The sliding plate is slidably connected in the connecting block. An insertion block corresponding to the through groove and the locking groove is fixedly connected to the other end of the sliding plate.

[0009] Preferably, the lock rod assembly includes an insertion rod movably arranged in the sliding groove. A sliding cavity is formed in the insertion rod, and a sliding plate is slidably connected inside the sliding cavity. A first spring is arranged between the sliding plate and the sliding cavity. A vertical block is fixedly connected to the upper end of the sliding plate.

[0010] Preferably, one end of the first spring is fixedly connected to the lower end of the sliding plate, and the other end of the first spring is fixedly connected to the lower part inside the sliding cavity.

[0011] Preferably, a plurality of installation grooves for installing the bent plates are formed outside the top seat, and a control terminal for receiving data information and controlling the electric plug lock is arranged inside the top seat.

[0012] Preferably, a connecting bent plate and a fixing bent plate are fixedly connected by bolts between every two adjacent bent plates. The connecting bent plate is arranged below the bent plate, and the fixing bent plate is arranged at an eccentric position of the bent plate.

[0013] Preferably, a connecting short plate is fixedly connected to the position near the center inside the bent plate, and jacks corresponding to the sliding groove and the lock rod assembly are provided on the connecting short plate.

[0014] Compared with the prior art, the technical solution of the present invention has the following advantages: (1) During construction, the strut mechanism can support the top seat through the cooperation with the main support rod, which can effectively prevent the main support rod from deforming due to pressure offset during installation. After the construction is completed, the secondary support rod is unlocked through the lock rod assembly, one end of the secondary support rod is lifted, so that the sliding groove is aligned with the jack, and the lock rod assembly is inserted into the jack and the sliding groove to lock the secondary support rod on one side of the bent plate, which can further strengthen the internal strength of the bent plate and enhance the structural stability of the bent plate, preventing the bent plate from deforming when vibrating. Since the semicircular shape formed by the bent plates has a relatively high overall seismic resistance, the strut mechanism is firstly used for support during installation and secondly for secondary structural enhancement after construction is completed; (2) A rotating strut is also provided in the strut mechanism. When the terminal in the top seat receives an earthquake warning, the electric plug lock is powered, the lock rod of the electric plug lock retracts, the rotating strut loses the support force and disengages from the secondary support rod. Due to gravity, one end of the rotating strut swings to the ground, and the rotating strut is caught in the locking assembly, and the plug locks the rotating strut. The rotating strut and the bent plate form a triangle, which further enhances the stability between the bottom of the bent plate and the ground, increases the building support points, and prevents the bent plate from deforming due to vibration.

[0019] As Figures 1 to 11As shown in the figure, a seismic spherical grid structure for a steel structure building provided by the present invention includes a top seat 1 and a base 2 arranged below the top seat 1 for providing support force. The base 2 is buried in the ground, and the upper surface of the base 2 is flush with the ground. A plurality of bent plates 4 are arranged outside the top seat 1, and a plurality of sets of support rod mechanisms 3 for supporting the bent plates 4 are arranged outside the base 2. A plurality of U-shaped frames 21 for locking the support rod mechanisms 3 are fixedly connected to the upper end of the base 2. The U-shaped frames 21 are annularly arranged around the axis of the base 2. Through holes 22 are formed in the U-shaped frames 21. A main support rod 23 is fixedly connected to the upper end of the base 2, and a connecting seat 24 is fixedly connected to the upper end of the main support rod 23. A plurality of rotation grooves 25 corresponding to the support rod mechanisms 3 are formed outside the connecting seat 24. The support rod mechanism 3 includes a secondary support rod 31 rotatably connected in the rotation groove 25. A sliding groove 32 is formed at the lower end of the secondary support rod 31. The sliding groove 32 corresponds to the through hole 22, and a lock rod assembly 36 for locking the secondary support rod 31 on the U-shaped frame 21 is arranged in the sliding groove 32.

[0020] In this embodiment, the secondary support rod 31 is locked on the U-shaped frame 21 through the lock rod assembly 36, so that the secondary support rod 31 is perpendicular to the ground. The secondary support rod 31 and the main support rod 23 support the top seat 1 at the same time. Multiple support structures support the top seat 1, increasing the support stability of the building. When the building construction is completed, one end of the secondary support rod 31 is used to remove the secondary support rod 31 from the U-shaped frame 21, lift one end of the secondary support rod 31, and connect the secondary support rod 31 with the bent plate 4 through the lock rod assembly 36 to increase the structural strength of the bent plate 4.

[0021] A placement cavity is formed on one side of the secondary support rod 31. A lock hole is formed in the inner wall of the placement cavity. A rotating support rod 33 is arranged in the placement cavity. The rotating support rod 33 is rotatably connected to the lower part of the inner wall of the placement cavity. An electric plug lock 34 corresponding to the lock hole is fixedly arranged in the rotating support rod 33. In the case of no power supply, the lock rod of the electric plug lock 34 is inserted into the lock hole in the secondary support rod 31 to fix the rotating support rod 33 in the secondary support rod 31. A locking groove 35 is formed at the other end of the rotating support rod 33.

[0022] The support rod mechanism 3 further includes a locking component 37 arranged on the ground corresponding to one end of the rotating support rod 33. The locking component 37 includes a fixed stop block 371 fixedly arranged on the ground. A groove corresponding to the rotating support rod 33 is formed in the fixed stop block 371, and a through groove is formed in the groove.

[0023] Through grooves are formed on both sides of the groove in the fixed stop block 371. Connecting blocks 372 are fixedly connected to both sides of the fixed stop block 371. Second springs 373 are respectively fixedly connected to the two connecting blocks 372. The other ends of the second springs 373 are fixedly connected to a sliding plate 374. The sliding plate 374 is slidably connected in the connecting block 372. An insertion block 375 corresponding to the through groove and the locking groove 35 is fixedly connected to the other end of the sliding plate 374.

[0024] The lock rod assembly 36 includes a plug rod 361 movably arranged in the sliding groove 32. A sliding cavity 362 is formed in the plug rod 361. A sliding plate 363 is slidably connected inside the sliding cavity 362. A first spring 364 is fixedly connected to the lower end of the sliding plate 363. The other end of the first spring 364 is fixedly connected to the lower part inside the sliding cavity 362. A vertical block 365 is fixedly connected to the upper end of the sliding plate 363.

[0025] A plurality of mounting grooves 11 for mounting the bent plates 4 are formed on the outer side of the top seat 1. A control end is arranged inside the top seat 1, which is a control terminal for receiving data information and controlling the electric plug lock 34. When the control terminal in the top seat 1 receives the earthquake early warning information, the electric plug lock 34 is powered on, so that the lock rod of the electric plug lock 34 retracts, and the lock rod disengages from the lock hole in the secondary support rod 31. Due to gravity, the rotating support rod 33 disengages from the secondary support rod 31 and one end contacts the fixed stop block 371 on the ground.

[0026] A connecting bent plate 41 and a fixed bent plate 42 are fixedly connected between every two adjacent bent plates 4 by bolts. The connecting bent plate 41 is arranged below the bent plate 4, and the fixed bent plate 42 is arranged at an eccentric position of the bent plate 4.

[0027] A connecting short plate 43 is fixedly connected at a position near the center inside the bent plate 4. A jack 431 corresponding to the sliding groove 32 and the lock rod assembly 36 is formed on the connecting short plate 43. When one end of the secondary support rod 31 is fixed on the connecting short plate 43 through the lock rod assembly 36, the secondary support rod 31 strengthens the strength of the bent plate 4, improves the structural stability, and prevents the bent plate 4 from deforming.

[0028] The working principle of the present invention: During construction, one end of the secondary support rod 31 is locked on the U-shaped frame 21 by the lock rod assembly 36, and the secondary support rod 31 is perpendicular to the ground. At this time, a plurality of secondary support rods 31 and the main support rod 23 simultaneously provide support force for the top seat 1, preventing the main support rod 23 from deforming due to pressure offset problems during building construction and affecting the building stability. After the construction is completed, the vertical block 365 is pressed into the sliding cavity 362, the plug rod 361 is pulled out from the sliding groove 32 and the through hole 22 to unlock the secondary support rod 31. One end of the secondary support rod 31 is lifted to align the sliding groove 32 with the jack 431, and the plug rod 361 is inserted into the sliding groove 32 and the jack 431 to fix one end of the secondary support rod 31 on the connecting short plate 43, so that the secondary support rod 31 strengthens the stability of the bent plate 4. During an earthquake, the terminal in the top seat 1 receives an earthquake warning and supplies power to the electric plug lock 34. The locking rod of the electric plug lock 34 retracts and no longer inserts into the lock hole in the auxiliary support rod 31. The rotating support rod 33 loses its supporting force and disengages from the auxiliary support rod 31. One end of the rotating support rod 33 swings to the ground and, due to gravity, smashes into the fixed stop block 371. At the same time, it squeezes the inclined surface of the extrusion insert block 375, and the insert block 375 is squeezed into the connecting block 372. After the rotating support rod 33 is completely stuck in the fixed stop block 371, the second spring 373 pushes out the insert block 375 through the sliding plate 374, and the insert block 375 inserts into the locking groove 35, fixing one end of the rotating support rod 33 in the fixed stop block 371. At this time, a stable triangular-like structure is formed between the rotating support rod 33 and the bent plate 4, increasing the building support points and the overall structural stability, and preventing the building from deforming.

[0029] The above embodiments are only exemplary embodiments of the present invention and are not used to limit the present invention. The protection scope of the present invention is defined by the claims. Those skilled in the art can make various modifications or equivalent replacements within the essence and protection scope of the present invention, and such modifications or equivalent replacements should also be regarded as falling within the protection scope of the present invention.
