Technical Field

[0001] This invention relates to the field of steel structure technology, specifically to a thermally insulated and safe steel structure and its assembly method. Background Technology

[0002] Steel structures are structures made of steel materials and are one of the main types of building structures. They are characterized by high strength, light weight, good overall rigidity, and strong deformation capacity. They are usually used to construct large-span, super-high, and super-heavy buildings.

[0003] Currently, Chinese patent application number CN202222775972.0 discloses a flame-retardant and heat-insulating safety steel structure, including an outer flame-retardant layer and a steel structure body. An inner flame-retardant layer is fixedly connected to the inner side of the outer flame-retardant layer, a drying layer is fixedly connected to the inner side of the inner flame-retardant layer, an outer heat-insulating layer is fixedly connected to the inner side of the drying layer, an inner heat-insulating layer is fixedly connected to the inner side of the outer heat-insulating layer, and a protective inner layer is fixedly connected to the inner side of the inner heat-insulating layer.

Furthermore, due to the large gaps between steel structures, it is inconvenient to install insulation panels at the bottom of the steel components, creating a risk of localized heat loss and resulting in poor insulation and aesthetics. In addition, traditional filling processes usually use fixed nozzles to spray foaming materials inside the steel components, which can easily cause uneven filling and affect the insulation performance of the steel structure.

[0016] Compared with the prior art, the beneficial effects of the present invention are: The thermal insulation and safety steel structure of this invention can change the positional distance between the first and second steel components to adapt to different span load requirements and improve structural adaptability. The inner surfaces of the first and second steel components are provided with an expanded graphene coating to provide certain fire resistance. Inside the expanded graphene coating, a composite system formed by water-based foamed polyurethane and 5%-10% expanded perlite powder is filled. After spraying and filling, foaming is achieved by reacting isocyanate with polyol, resulting in a volume expansion rate of 300%-500%. The addition of expanded perlite powder enhances the flame retardant performance, thereby reducing the thermal conductivity of the first and second steel components and achieving thermal insulation. Furthermore, the optimized use of a snap-on structure allows the external snap-on panel or insulation board to be locked below, forming a flat interface with insulation on one side, further improving thermal insulation and aesthetics.

[0017] This invention optimizes the use of filling equipment in the assembly method of thermally insulated and safe steel structures. The two sides of the drive guide component can be extended outward to ensure that it is in a centered position after being inserted into the steel component. Under the action of the drive guide component, the sliding column drives the roller to move laterally. The displacement of the roller changes the stroke of the amplitude adjustment component. Thus, under the action of the drive guide component, the amplitude adjustment component drives the nozzle to make a back-and-forth swinging motion, thereby improving the filling uniformity of the composite system filler formed by water-based foamed polyurethane and 5%-10% expanded perlite powder inside the steel component.

[0018] This invention utilizes a bidirectional screw and two second internally threaded cylinders to move two hollow rectangular rods and an inner rod closer or further apart, adapting to the internal dimensions of steel components of different sizes. The two hollow rectangular rods slide through the front and rear side walls of the storage unit, with the storage unit providing limiting support to ensure the stability of their displacement. After the hollow rectangular rods and inner rods have moved and adjusted, the support rollers contact the inner wall of the steel component, providing guiding support and ensuring that the frame remains in the middle position inside the steel component during pushing and pulling, thus improving the uniformity of filling.

[0019] In this invention, after the roller changes its position laterally, it drives the sliding sleeve to move and change its lateral position on the rotating rod surface. After the sliding sleeve changes its lateral position, the protruding column drives the two levers to rotate on the arc-shaped rod. Under the action of the levers, the second sliding column changes its position along the arc-shaped trajectory inside the arc-shaped rod. The second sliding column drives the swing rod to adjust its position, thereby changing the angle between the swing rod and the rotating frame. Then, when the rotating rod rotates, it drives the rotating frame and the nozzle to perform a reciprocating motion with an adjustable back-and-forth swing amplitude. Attached Figure Description

[0032] The filling device includes a handle 61, a rod 62 fastened to one side of the handle 61, a positioning structure 63 fastened to the side of the rod 62 away from the handle 61, a nozzle 64 installed at the left end of the positioning structure 63, a hose 65 connected to the rear side of the nozzle 64, and a switch 66 located on the right rear side of the rod 62. A feed pipe is located behind the switch 66, and the other side of the hose 65 is connected to the feed pipe. The other side of the feed pipe is connected to the external filler end, so that the external water-based polyurethane foam and 5%... The composite filler system formed by -10% expanded perlite powder is sprayed out from the nozzle 64 through the hose 65 after the switch 66 is activated. Limiting sleeves 651 are provided on both the left and right sides of the rod 62. The hose 65 is inserted through the two limiting sleeves 651 to limit the hose 65 and prevent it from moving. The positioning structure 63 includes a drive guide assembly 631 that is fastened to the rod 62 at the middle of the right side, and a support seat 632 that is fixed to the middle of the left side of the drive guide assembly 631. A frame 633 is fixedly connected to the left side of the support base 632; a slide post 634 slides through the right side of the front part of the frame 633; ​​a roller 635 is rotatably connected to the left end of the slide post 634; and an amplitude adjustment assembly 636 is connected to the rear side of the roller 635.

The amplitude adjustment assembly 636 is rotatably connected inside the frame 633, and the right end of the amplitude adjustment assembly 636 is connected to the drive guide assembly 631. The left end of the amplitude adjustment assembly 636 is connected to... The nozzle 64 is fastened, and the two sides of the drive guide assembly 631 can be extended outward to ensure that it is in the center position after being inserted into the steel component. Under the action of the drive guide assembly 631, the slide column 634 drives the roller 635 to move laterally. The displacement of the roller 635 changes the required stroke of the amplitude adjustment assembly 636. Thus, under the action of the drive guide assembly 631, the amplitude adjustment assembly 636 drives the nozzle 64 to make a back-and-forth reciprocating swing motion to improve the uniformity of the filler.

[0033] The drive guide assembly 631 includes a housing 6311 fastened to the rod 62 at the middle of its right side, a support plate 6312 fixedly connected to the middle of the interior of the housing 6311, a first drive body 6313 installed on the left rear of the support plate 6312, and a rotating shaft 6314 coaxially rotating at the middle of the output end of the first drive body 6313. The rotating shaft 6314 passes through and rotates through the middle of the left side wall of the housing 6311, and the left end of the rotating shaft 6314 is connected to the amplitude adjustment assembly 636. Under the action of the first drive body 6313, the rotating shaft 6314 drives the amplitude adjustment component 636 to perform a swinging action. The system includes a second drive body 6315 located on the front left side of the support plate 6312, a threaded rod 6316 connected to the middle of the output end of the second drive body 6315, a first internal threaded cylinder 6317 threaded to the left side of the outer surface of the threaded rod 6316, and a guide component 6318 penetrating the front and rear sides of the compartment 6311. The first internal threaded cylinder 6317 slides through the front left side wall of the compartment 6311, and its left end is fixed to the sliding column 634. Under the action of the second drive body 6315, the threaded rod 6316 rotates inside the first internal threaded cylinder 6317, thereby driving the sliding column 634 to move laterally through the cooperation of the threaded rod 6316 and the first internal threaded cylinder 6317. The guide component 6318 is installed on the right side of the support plate 6312. After the guide component 6318 moves, it moves laterally towards the sliding column 634. Extending from both the front and rear sides, it supports and guides the steel structure, ensuring its centered position. A protrusion 63171 is fixedly connected to the front right side of the first internal threaded cylinder 6317. Both the first internal threaded cylinder 6317 and the protrusion 63171 slide through the inside of the limiting frame 63172, and the bottom side of the limiting frame 63172 is fixed to the housing seat 6311, which plays a limiting and supporting role, so that the first internal threaded cylinder 6317 does not produce its own rotation movement, ensuring the stability of displacement.

[0034] The guide component 6318 includes a third drive body 63181 connected to the support plate 6312 on the left side, a bidirectional screw 63182 fixed through and in the middle of the output end of the third drive body 63181, two second internal threaded cylinders 63183 threaded to the front and rear sides of the bidirectional screw 63182 respectively, two hollow rectangular rods 63184 fastened to the side of the two second internal threaded cylinders 63183 away from the bidirectional screw 63182 respectively, and two inner rods 63185 sliding through and in the interior of the two hollow rectangular rods 63184 away from the side of the second internal threaded cylinders 63183 respectively. Using the third drive body 63181 as a power source, the rotation of the bidirectional screw 63182 causes the two second internal threaded cylinders 63183 to move away from or closer to each other, thereby driving the two hollow rectangular rods 6318. 4. The inner rods 63185 are positioned far apart or close together to accommodate the internal dimensions of steel components of different sizes. The outer ends of the two inner rods 63185 are rotatably connected to support wheels 63186, and the inner ends of the two inner rods 63185 are connected to two hollow rectangular rods 63184 respectively via springs 63187. The two hollow rectangular rods 63184 slide through the front and rear side walls of the storage base 6311, and the storage base 6311 provides limiting support for the hollow rectangular rods 63184 to ensure the stability of the hollow rectangular rods 63184 during displacement. After the hollow rectangular rods 63184 are moved and adjusted, the support wheels 63186 contact the inner wall of the steel component to provide guiding support, ensuring that the frame 633 is located in the middle position inside the steel component during the pushing and pulling process, thereby improving the uniformity of filling.

[0035] The first drive body 6313, the second drive body 6315, and the third drive body 63181 have the same structure, each consisting of a servo motor and two meshing gears. The servo motor output is connected to the middle of one gear, and the middle of the other gear serves as the output to transmit power to the outside, so as to provide power for the drive of the components through the servo motor. Slide bars 631831 are fixedly connected to the right side of the two second internal threaded cylinders 63183. The slide bars 631831 are inserted and slide inside the left side of the slider 631832, and the right side of the slider 631832 is fixed to the housing 6311, ensuring that the second internal threaded cylinders 63183 do not rotate on their own, so that they can perform stable forward and backward displacement movements in cooperation with the bidirectional screw 63182.

[0036] The amplitude adjustment component 636 includes a rotating rod 6361 connected at its right end to a rotating shaft 6314, which causes the rotating rod 6361 to rotate. It also includes a sliding sleeve 6362 slidably connected to the outer surface of the rotating rod 6361, a protrusion 6363 located on the top left side of the sliding sleeve 6362, two shift forks 6364 slidably connected to the front and rear sides of the protrusion 6363, an arc-shaped rod 6365 fixedly connected to the left side of the rotating rod 6361, and a second sliding rod 6365 penetrating and sliding inside the arc-shaped rod 6365. 366. A swing rod 6367 connected to the front and rear sides of the sliding column 6366 and a rotating frame 6368 rotating inside the left side of the swing rod 6367. The rotating frame 6368 is rotatably connected to the left side inside the frame 633, and the left end of the rotating frame 6368 is fastened to the nozzle 64 so that the rotating frame 6368 drives the nozzle 64 to perform a stable back-and-forth swinging motion. The right side of the rotating rod 6361 passes through and rotates inside the support 632 and the frame 633 to ensure the stability of the rotation of the rotating rod 6361. The front of the sliding sleeve 6362... The right side of the part is connected to the roller 635. After the roller 635 changes its position laterally, it drives the sliding sleeve 6362 to move and change its lateral position on the surface of the rotating rod 6361. The middle part of the two shift fork rods 6364 is rotatably connected to the arc-shaped rod 6365, and the two shift fork rods 6364 are respectively slidably connected to the front and rear ends of the sliding column 6366. The arc-shaped rod 6365 is set inside the right side of the swing rod 6367. After the lateral position of the sliding sleeve 6362 changes, the protrusion 6363 drives the two shift fork rods 6364 to move. 364 rotates on the arc-shaped rod 6365 by an angle, so that under the action of the fork lever 6364, the sliding column 6366 changes position along the arc-shaped trajectory inside the arc-shaped rod 6365, so that the sliding column 6366 drives the swing rod 6367 to rotate and adjust its position, thereby changing the angle between the swing rod 6367 and the rotating frame 6368. Then, when the rotating rod 6361 rotates, it drives the rotating frame 6368 to perform a reciprocating motion with an adjustable back-and-forth swing amplitude, so that the nozzle 64 sprays the filler material back and forth, ensuring a uniform filling effect.

[0037] The working principle of the filling equipment is as follows: First, after installing the first steel component 1 and the second steel component 3, connect the filler end of the composite system formed by external water-based foamed polyurethane and 5%-10% expanded perlite powder to the feed pipe on switch 66 to use the filling equipment. Second, the user grips the handle 61 and controls the activation of the third drive body 63181 according to the internal dimensions of the first steel component 1 and the second steel component 3. Under the action of the third drive body 63181, the bidirectional screw 63182 rotates. Through the cooperation of the bidirectional screw 63182 and the two second internal threaded cylinders 63183, the two hollow rectangular rods 63184 and the inner rod 63185 move away from or closer to each other, changing the positional distance between the two support wheels 63186 to adapt to the internal dimensions of steel components of different sizes. Third, based on the internal dimensions of the first steel component 1 and the second steel component 3, the second drive body 6315 is activated. Under the action of the second drive body 6315, the threaded rod 6316 rotates inside the first internal threaded cylinder 6317. Through the cooperation between the threaded rod 6316 and the first internal threaded cylinder 6317, the sliding column 634 is moved laterally. After the sliding column 634 is moved, the roller 635 changes its position laterally, causing the sliding sleeve 6362 to move and change its position on the rotating rod 63. At the lateral position of the surface 61, the protrusion 6363 on the sliding sleeve 6362 drives the two fork levers 6364 to rotate on the arc-shaped rod 6365. Under the action of the fork levers 6364, the sliding column 6366 changes position along the arc-shaped trajectory inside the arc-shaped rod 6365. The sliding column 6366 drives the swing rod 6367 to rotate and adjust its position, thereby changing the angle between the swing rod 6367 and the rotating frame 6368, and thus adjusting and changing the amplitude of the swinging of the rotating frame 6368. Fourth, insert the nozzle 64 into the first steel component 1, so that the two support wheels 63186 contact the inner wall of the first steel component 1 for guidance and support. Then push the nozzle 64 to the innermost side and start the control of the first drive body 6313. Under the action of the first drive body 6313, the rotating shaft column 6314 rotates through the rotating rod 6361 and the arc-shaped rod 6365. With the cooperation of the arc-shaped rod 6365 and the swing rod 6367, the rotating frame 6368 drives the nozzle 64 to perform a back-and-forth reciprocating swinging motion. Then, start the switch 66 to make the composite system filler formed by the external water-based foamed polyurethane and 5%-10% expanded perlite powder spray out from the nozzle 64 through the hose 65. The sprayed filler swings back and forth to improve the uniformity of filling. As the filler is sprayed out, it pulls the position of the nozzle 64 outward until the interior of the first steel component 1 is filled. Then, the interior of the second steel component 3 is filled.
