Abstract
Description
Technical Field
[0001] This utility model relates to the field of steel structure technology, and in particular to a steel structure node positioning and installation device. Background Technology
[0002] Steel structures are structures made of steel materials and are one of the main types of building structures. The structure mainly consists of steel beams, steel columns, steel trusses, and other components made of shaped steel and steel plates, and employs rust removal and prevention processes such as silanization, pure manganese phosphating, water washing and drying, and galvanizing. The various components are typically connected by welds, bolts, or rivets. Due to their light weight and simple construction, they are widely used in large factories, stadiums, high-rise buildings, bridges, and other fields.
[0003] Chinese patent CN221523813U discloses a steel structure and membrane structure node installation device, specifically relating to the field of node installation technology. It includes a connecting column, with screws meshing at both the lower front and rear ends of the connecting column. A second steel structure assembly is fixedly connected to both the left and right ends of the connecting column. A fixing block is fixedly connected to the middle of the upper end of the connecting column. A through groove is formed at the front right end of the fixing block, and a ring is fitted inside the through groove. A membrane structure assembly is fitted inside the ring. The first steel structure assembly is fixedly connected to the middle of the front end of the connecting column. This utility model's steel structure and membrane structure node installation device, through the second and first steel structure assemblies, enables rapid assembly of steel beams. Through the membrane structure assembly, the device installs membrane materials and can adjust the tension of the membrane material, thus enabling the device to simultaneously possess the capabilities of both steel and membrane structures, improving its practicality.
[0004] When assembling steel structures, assembly is often carried out simultaneously from both ends. When assembling to the connection node, a connecting frame is used to connect the two crossbeams together. However, due to potential errors when assembling simultaneously from both ends, the two crossbeams at the connection node may not be at the same height. The connecting frame can only align with one crossbeam, leaving a gap between it and the other. The aforementioned patented bolts and nuts forcibly fix the crossbeams, causing them to be squeezed and deformed, generating internal stress and affecting safety. In addition, the aforementioned patent does not have a shock absorption function and is difficult to effectively absorb the vibrations experienced by the crossbeams. Therefore, in view of the above situation, there is an urgent need to develop a steel structure node positioning and installation device that is easy to install and adjust, reduces the squeezing deformation of the H-shaped steel beams during connection, has a shock absorption function, and is safer, in order to overcome the shortcomings in current practical applications and meet current needs. Utility Model Content
[0005] The purpose of this utility model is to provide a steel structure node positioning and installation device to solve the problems mentioned in the background art.
[0006] To achieve the above objectives, the present invention adopts the following technical solution:
[0007] A steel structure node positioning and installation device includes an outer frame, height adjustment mechanisms, and positioning support plates. Two height adjustment mechanisms are provided, each with a fixedly connected positioning support plate. A shock-absorbing pad is fixed to the upper side of each positioning support plate. The positioning support plate is used to connect to the H-shaped steel beams of the steel structure. A shock-absorbing mechanism is installed on each of the left and right sides inside the outer frame. Each height adjustment mechanism includes a threaded rod, a threaded sleeve, a sliding sleeve, and a limiting rod. The threaded rod is rotatably connected inside the outer frame, and a threaded sleeve is installed on the threaded rod. The positioning support... The plate is welded and fixed to the threaded sleeve. There are two sliding sleeves, which are fixed to both sides of the positioning support plate. Each sliding sleeve is slidably mounted on a limiting rod, which is fixed inside the outer frame. The damping mechanism includes a damper, a base plate, a connecting plate, a guide rod, and a damping spring. The damper is fixed inside the outer frame, and the piston rod of the damper is fixed to the base plate. Multiple guide rods penetrating the base plate are fixed to the lower side of the connecting plate. A damping spring is installed on the outer side of each guide rod. The upper end of the damping spring is fixed to the connecting plate, and the lower end is fixed to the base plate.
[0008] Preferably, the two height adjustment mechanisms are arranged symmetrically about the center line of the outer frame.
[0009] Preferably, the shock-absorbing pad is made of silicone rubber.
[0010] Preferably, both the positioning support plate and the shock-absorbing pad are provided with a first mounting hole, which is used for bolts to pass through.
[0011] Preferably, the upper end of the threaded rod is fixed with a rotating handle, which is used by hand to rotate the threaded rod.
[0012] Preferably, the guide rod is slidably connected to the substrate.
[0013] Preferably, the connecting plate is provided with a plurality of second mounting holes for bolts to pass through.
[0014] Preferably, a limiting baffle is fixed at the bottom of each guide rod.
[0015] The beneficial effects of this utility model are as follows: During installation, the steel structure node positioning and installation device allows for manual rotation of the handle to rotate the threaded rod. This rotation of the threaded rod causes the threaded sleeve to move up and down, which in turn moves the positioning support plate up and down, bringing the positioning support plate into contact with the H-beam. Bolts and nuts are then used to fix the positioning support plate and the H-beam together, reducing the deformation of the H-beam during the fixed connection, lowering the internal stress of the H-beam, and improving safety. Bolts are then used to fix the connecting plate to the H-beam. This process fixes both steel beams of the node within the outer frame. When the H-beam is subjected to vibration, the damping pads can absorb some of the vibration. The vibration causes the damping spring to deform, which in turn causes the connecting plate and guide rod to move up and down. The damping spring then transmits the vibration force to the base plate and damper, where the damper absorbs and converts the vibration force, thereby reducing the impact of vibration on the H-beam. In summary, this utility model is easy to install and adjust, reduces the squeezing deformation of the H-beam during connection, and has a shock absorption function, making it safer.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.
[0025] Specific implementation examples are given below.
[0026] See Figures 1-6 In this embodiment of the present invention, a steel structure node positioning and installation device includes an outer frame 1, a height adjustment mechanism 2, and a positioning support plate 3. There are two height adjustment mechanisms 2, symmetrically arranged about the center line of the outer frame 1. Each height adjustment mechanism 2 is fixedly connected to a positioning support plate 3. A shock-absorbing pad 301, made of silicone rubber, is fixed to the upper side of the positioning support plate 3 to effectively absorb vibrations. The positioning support plate 3 is used to connect the H-shaped steel beams of the steel structure. Each of the 01 sections is provided with a first mounting hole 302 for bolts to pass through. A damping mechanism 4 is installed on both the left and right sides inside the outer frame 1. The damping mechanism 4 is used to dampen the H-shaped steel beam. In use, the height of the positioning support plate 3 is adjusted by the height adjustment mechanism 2 so that the positioning support plate 3 is in contact with the H-shaped steel beam. Then, bolts and nuts are used to fix the positioning support plate 3 to the H-shaped steel beam. Then, bolts and nuts are used to fix the damping mechanism 4 to the H-shaped steel beam. By doing this, both steel beams of the node can be fixed inside the outer frame 1.
[0027] The height adjustment mechanism 2 includes: a threaded rod 201, a threaded sleeve 202, a sliding sleeve 203, and a limiting rod 204. The threaded rod 201 is rotatably connected to the outer frame 1. A rotating handle 2011 is fixed to the upper end of the threaded rod 201. The rotating handle 2011 is used for manual rotation to drive the threaded rod 201 to rotate. The threaded sleeve 202 is installed on the threaded rod 201. The positioning support plate 3 is welded and fixed to the threaded sleeve 202. There are two sliding sleeves 203, which are fixed to both sides of the positioning support plate 3. Each sliding sleeve 203 is slidably mounted on a limiting rod 204. 204 is fixed inside the outer frame 1. The movement of the positioning support plate 3 and the threaded sleeve 202 is restricted by the sliding sleeve 203 and the limiting rod 204, preventing them from rotating and allowing them to move only in a straight line. In use, the rotating handle 2011 is turned by hand to drive the threaded rod 201 to rotate. The rotation of the threaded rod 201 drives the threaded sleeve 202 to move up and down, which in turn drives the positioning support plate 3 to move up and down. This makes the positioning support plate 3 fit against the H-beam, thereby reducing the deformation of the H-beam when it is fixedly connected to the positioning support plate 3, reducing the internal stress of the H-beam, and improving safety.
[0028] The damping mechanism 4 includes: a damper 401, a base plate 402, a connecting plate 403, guide rods 404, and damping springs 405. The damper 401 is fixed inside the outer frame 1, and the piston rod of the damper 401 is fixed to the base plate 402. Multiple guide rods 404 penetrating the base plate 402 are fixed to the lower side of the connecting plate 403. The guide rods 404 are slidably connected to the base plate 402. A limiting baffle 4041 is fixed to the bottom of each guide rod 404, and a damping spring 405 is installed on the outer side of each guide rod 404. The upper end of the damping spring 405 is connected to the connecting plate. The lower end of the connecting plate 403 is fixed to the base plate 402. The connecting plate 403 is provided with multiple second mounting holes 4031 for bolts to pass through. In use, the connecting plate 403 is fixed to the H-beam with bolts. When the H-beam is vibrated, the damping spring 405 deforms and drives the connecting plate 403 and the guide rod 404 to move up and down. The damping spring 405 then transmits the vibration force to the base plate 402 and the damper 401. The damper 401 absorbs and converts the vibration force, thereby reducing the impact of vibration on the H-beam.
[0029] Working principle: During installation, the steel structure node positioning and installation device works by manually rotating the handle 2011, which in turn rotates the threaded rod 201. This rotation of the threaded rod 201 causes the threaded sleeve 202 to move up and down, which in turn moves the positioning support plate 3 up and down. This allows the positioning support plate 3 to fit against the H-beam. Bolts and nuts are then used to secure the positioning support plate 3 to the H-beam, reducing deformation during the connection and lowering the internal stress of the H-beam, thus improving safety. Then, the connecting plate 403 is fixed to the H-beam with bolts. In this way, both steel beams of the node are fixed to the outer frame 1. When the H-beam is subjected to vibration, the damping pad 301 can absorb the vibration to a certain extent. The vibration causes the damping spring 405 to deform and causes the connecting plate 403 and guide rod 404 to move up and down. The damping spring 405 then transmits the vibration force to the base plate 402 and the damper 401. The damper 401 absorbs and converts the vibration force, thereby reducing the impact of vibration on the H-beam.
