Description

Technical Field

[0001] This invention relates to the field of steel structure building technology, and in particular to a prefabricated steel structure ceiling structure and a steel structure building. Background Technology

[0002] With the development of industrialized construction, prefabricated steel structure buildings have been widely used in large factories, stadiums, and multi-story buildings due to their advantages such as fast construction speed and high degree of component standardization. In these buildings, the ceiling system, as an important spatial partition and decorative component, directly affects the overall construction progress due to its installation efficiency. Traditional steel structure building ceilings often use welding and bolt connections to fix the hanging components to the I-beam main beam to meet load-bearing and positioning requirements.

[0003] However, the traditional installation methods described above have the following drawbacks: the connection between the hangers and the I-beams is made by bolts or welding, which makes it difficult to adjust their position once fixed, resulting in low assembly efficiency and easy damage to the components; it also requires high professional skills from the installation workers, increasing labor costs and training difficulties. Therefore, there is an urgent need to develop a connection structure that enables rapid, flexible, and tool-free installation between the hangers and the I-beam main beams, in order to significantly improve the construction efficiency of prefabricated steel structure buildings. Summary of the Invention

[0004] To address the above problems, the present invention provides the following technical solution:

[0005] A prefabricated steel structure ceiling includes an I-beam and a quick-assembly assembly. The quick-assembly assembly includes hinges installed inside the I-beam, through which a hanger is quickly assembled onto the I-beam. A first long slot is formed inside the I-beam, and two hinges are located at the same position in the first long slot. The first chain links of the two hinges are located on one side of the first long slot and close to the inner wall of the I-beam and are fixed. The second chain links of the two hinges extend into the first long slot and are adjacent to each other. The adjacent ends of the two second chain links of the two hinges are respectively provided with arc-shaped openings, and the two arc-shaped openings together form a circular through hole vertically above the first long slot. The bottom end of the hanger is located on the bottom side of the I-beam, and the top end of the hanger passes through the first long slot and the circular through hole into the I-beam. A reinforcing bar is welded to the top end of the hanger for quick suspension on the top surface of the two second chain links. The diameter of the reinforcing bar is smaller than the distance between the two second chain links.

[0006] As a further preferred embodiment, the first long slot is a rectangular slot opened along the length of the internal cavity structure of the I-beam, and a hanging array consisting of several combined pages and several hanging components is provided along the length of the first long slot.

[0007] As a further preferred embodiment, the quick-release assembly also includes a quick-release plate disposed within the I-beam, which presses only on the first chain link of all hinges, and the outer edges of the quick-release plate are spot-welded to the inner walls of both sides of the I-beam.

[0008] As a further preferred embodiment, the bottom surface of the quick-release plate is provided with a protrusion that engages with the first connecting hole on the first chain link of the hinge.

[0009] As a further preferred embodiment, a second long groove is provided in the middle of the quick-release plate. The second long groove is located above the second chain link. When the second chain link rotates upward, it can pass through the second long groove to reach the top of the quick-release plate.

[0010] As a further preferred embodiment, the quick-release assembly also includes locking elements and top blocks. Two locking elements slide on the top surface of the same second chain link, with a locking space between the two locking elements on the same second chain link. Two top blocks are provided on the same second chain link, with the two top blocks located on the outside of the locking elements. A guide rod is installed on the side of the locking element facing the top block. A top spring is filled inside the top block and is sleeved on the guide rod. The guide rod passes through the top block and is slidably assembled on the top block. A buckle is fixed on the bottom surface of the top block and buckles into the second connecting hole of the second chain link. The opposite ends of the two locking elements on the same second chain link have rounded corners.

[0011] As a further preferred embodiment, the bottom end of the lifting component is provided with a connecting part.

[0012] A steel structure building is assembled by the following steps: A first long groove is cut into several I-beams along the length of their webs, and the two ends of the I-beams are welded together to form a polygonal frame structure. Multiple hinges are assembled, and quick-release plates and quick-release components are installed according to the original positions of the first and second connecting holes. A protrusion corresponding to the first connecting hole is provided on the bottom surface of the quick-release plate, and a fastener corresponding to the second connecting hole is provided on the bottom surface of the top block of the quick-release component. A suitable number of hangers are selected, and the hangers are suspended one by one from the I-beams using hinges. The positions are locked by the quick-release components and quick-release plates, so that all the hangers are arranged in an array on the I-beams. Finally, the object is suspended from the ceiling using the connecting parts at the bottom of the hangers.

[0013] The advantages of this invention compared to the prior art are:

[0014] The core advantage lies in its "tool-free, rotation-locking" installation mode for the hangers. The installation process requires only two simple actions: "insert-rotate," eliminating tedious procedures like welding and bolting. Installing a hanger takes only seconds, resulting in high assembly efficiency and significantly shortening the overall construction cycle of the ceiling system. The hinges are standard components readily available on the market, eliminating the need for custom molds. This makes procurement convenient and extremely low-cost, significantly reducing the material cost of the entire connection structure and fully utilizing standard components for cost-effectiveness. The structure, where the top surface of the hinge chain supports the welded reinforcing steel, provides a stable and reliable load-bearing point. Once the hanger is rotated into position, it self-locks, preventing displacement or loosening. The large contact area between the reinforcing steel and the two chain links ensures even stress distribution. The first long groove within the I-beam allows the hinge assembly to slide and adjust its position along its length before or initially during installation, facilitating precise setting of the lifting points according to the ceiling design. If adjustment or replacement of the hanger is needed, simply rotate the hanger in the opposite direction to align the top reinforcing steel with the hinge chain, and the hanger can be removed downwards. Operation is equally simple and quick, offering greater flexibility. Attached Figure Description

Detailed Implementation

[0024] The above and other embodiments and advantages of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0025] In one implementation, such as Figures 1-8 As shown:

[0026] This embodiment provides a prefabricated steel structure ceiling structure, including an I-beam 10 and a quick-assembly assembly. The quick-assembly assembly includes hinges 20 disposed within the I-beam 10, through which a hanging member 30 is quickly assembled onto the I-beam 10. A first elongated groove 101 is formed within the I-beam 10, and two hinges 20 are disposed at the same position within the first elongated groove 101. The first chain tabs 210 of the two hinges 20 are located on one side of the first elongated groove 101 and close to the inner wall of the I-beam 10 and are fixed thereon. The second chain tabs 220 of the two hinges 20 extend into the first elongated groove 101. The two hinges 20 are adjacent to each other, and the adjacent ends of the two second chain links 220 are respectively provided with arc-shaped openings 230. The two arc-shaped openings 230 together form a circular through hole 240 vertically above the first long groove 101. The bottom end of the hanger 30 is located on the bottom side of the I-beam 10. The top end of the hanger 30 passes through the first long groove 101 and the circular through hole 240 and enters the I-beam 10. A steel bar 310 is welded to the top end of the hanger 30 for quick suspension on the top surface of the two second chain links 220. The diameter of the steel bar 310 is smaller than the distance between the two second chain links 220.

[0027] The core of this invention's prefabricated steel structure ceiling structure lies in the ingenious use of the hinge characteristics of standard hinges and the internal space of the I-beam 10 to achieve rapid positioning and reliable suspension of the hanging component 30. The specific working principle is as follows: A first long groove 101 is opened on the inner side of the web of the I-beam 10, providing space for the lateral installation of the hinge 20. Two standard hinges 20 are placed parallel to each other above the same position on the web of the first long groove 101, with their first chain links 210 respectively attached and fixed to both sides of the inner wall of the I-beam 10, and their second chain links 220 extending into the area of ​​the first long groove 101 and moving towards the centerline of the first long groove 101. The adjacent ends of the two second chain links 220 are designed with arc-shaped openings 230. When the two second chain links 220 are close together, these two arc-shaped openings 230 approach a circle and together form a circular through hole 240 located directly above the first long groove 101. The bottom end of the lifting member 30 is located below the I-beam 10, and the top end of the lifting member 30 extends into the interior of the I-beam 10 through the first elongated groove 101 and the circular through hole 240. Before the lifting member 30 extends into the I-beam 10, the reinforcing bar 310 at the top of the lifting member 30 is laterally pressed between the two second chain links 220. Pushing the lifting member 30 upwards causes the reinforcing bar 310 to rotate upwards against the two second chain links 220, allowing it to pass through the first elongated groove 101 and enter the I-beam 10. Rotating the lifting member 30 causes the reinforcing bar 310 to rotate, thus allowing the reinforcing bar 310 to pass through the first elongated groove 101 and enter the I-beam 10. Rotating the lifting member 30 causes the reinforcing bar 310 to rotate, thus allowing the reinforcing bar 310 to... Figure 4 As shown, it is reliably hooked onto the top surface of the second chain link 220 of the two hinges 20. At this time, the steel bar 310 is supported by the two second chain links 220, and the weight of the lifting component 30 is evenly transmitted to the two second chain links 220 through the steel bar 310, and then transmitted to the H-beam 10 body through the first chain link 210, thereby realizing the rapid and stable suspension and positioning of the lifting component 30. The assembly efficiency is high, it is not easy to cause damage to the components, and the professional skills required for the installation workers are low, which reduces labor costs and training difficulties.

[0028] The first long slot 101 provides adjustment margin for the initial installation positioning of the hinge 20, allowing for flexible setting of the lifting point position within a certain range according to design requirements. Furthermore, the length dimension of the first long slot 101 is larger than the diameter of the circular through hole 240, providing sufficient operating space for the top of the hanger 30 and the passage of the reinforcing bar. According to the requirements of building ceilings, several hangers 30 often need to be suspended on the same I-beam 10. In addition to the long distance of the first long slot 101, multiple circular through holes 240 are also set at multiple positions on the first long slot 101 in the aforementioned manner. The through-hole 240 and the corresponding set of multiple combination flaps 20, that is, a hanging array consisting of several combination flaps 20 and several hanging parts 30 along the length direction of the first long groove 101, are used to quickly suspend several hanging parts 30; conversely, since the diameter of the reinforcing bar 310 is smaller than the distance between the two second chain links 220, by rotating the hanging part 30 in the opposite direction to drive the reinforcing bar 310 to the opposite end of the two second chain links 220, and pulling down with force, the hanging part 30 can be removed downwards, and the suspension position of the hanging part 30 can be adjusted by the same assembly method, making it more flexible to use. The design of the arc-shaped opening 230 forming a circular through-hole 240 ensures that the hanging part 30 is not obstructed during the passage and rotation. The technical requirements for the arc-shaped opening 230 are: the edge of the circular hole is smooth without sharp corners, burrs and flash, so as to smoothly guide the hanging part 30 to drive the reinforcing bar 310 to rotate to the locking position. When rotating 90 degrees perpendicular to the inner wall of the I-beam 10, friction is reduced. The rotatability of hinge 20 improves the assembly efficiency of the hanger 30. Hinge 20 itself is an assembly component, which can be applied to the top structure of this unit with slight modifications before assembly, further saving costs.

[0029] The quick-release assembly also includes a quick-release plate 40 disposed within the I-beam 10. The quick-release plate 40 presses only on the first chain link 210 of all hinges 20, and the outer edges of both sides of the quick-release plate 40 are spot-welded to the inner walls of both sides of the I-beam 10. The quick-release plate 40 acts as a covering layer to press the first chain link 210 of all hinges 20, restricting the displacement of the first chain link 210. At the same time, the first chain link 210 locks the free end of the second chain link 220, which is hinged to it, on the axis of the first long slot 101. If there are multiple hinges 20, the assembly efficiency is improved by quickly applying pressure through the quick-release plate 40.

[0030] The quick-release plate 40 has a protrusion 410 on its bottom surface, which engages with the first connecting hole 2101 on the first chain link 210 of the hinge 20. The clearance fit (H9 / h8) between the first connecting hole 2101 and the protrusion 410 allows for fine adjustment but limits horizontal displacement, while facilitating snap-fit. By utilizing the snap-fit ​​function of the quick-release plate 40, the first chain link 210 of the hinge 20 is positioned within the I-beam 10. The quick positioning of the first chain link 210 fixes the entire hinge 20 within the I-beam 10, improving assembly efficiency. The first connecting hole 2101 is actually the screw hole inherent in the first chain link 210. In this invention, the first connecting hole 2101 is used for quick positioning by the quick-release plate 40, minimizing the need for secondary processing of the hinge 20.

[0031] The quick-release plate 40 has a second long groove 420 in the middle, which is located above the second chain link 220. When the second chain link 220 rotates upward, it can pass through the second long groove 420 to reach the top of the quick-release plate 40. When the second chain link 220 is lifted upward by the steel bar 310 and flips, the hinge end of the second chain link 220 moves along an arc and passes through the second long groove 420 to quickly complete the suspension above the quick-release plate 40.

[0032] The quick-release assembly also includes a locking element 50 and a top block 51. Two locking elements 50 slide on the top surface of the same second chain link 220. A locking space 510 is left between the two locking elements 50 on the same second chain link 220. Two top blocks 51 are provided on the same second chain link 220. The two top blocks 51 are located on the outside of the locking elements 50 respectively. A guide rod 520 is installed on the side of the locking element 50 facing the top block 51. A top spring 511 is filled in the top block 51. The top spring 511 is sleeved on the guide rod 520. The guide rod 520 passes through the top block 51 and is slidably assembled on the top block 51. A buckle 512 is fixed on the bottom surface of the top block 51. The buckle 512 is fastened in the second connecting hole 2201 of the second chain link 220. The opposite ends of the two locking elements 50 on the same second chain link 220 are provided with rounded corner surfaces 2202.

[0033] The buckle 512 engages with the second connecting hole 2201 of the second chain link 220 to fix the top block 51, so that the top spring 511 at the other end of the top block 51 is fitted onto the guide rod 520. The guide rod 520 is fixed to the locking member 50. Two locking members 50 are set on the same second chain link 220 in the same manner, and a locking space 510 is formed between the two locking members 50. After the steel bar 310 is rotated 90 degrees, it falls exactly between the two locking members 50. Pulling down the lifting member 30 with force will cause the steel bar to be dragged downwards. 310. The outer circular surface of the reinforcing bar 310 is pressed against the rounded corner surface 2202 of the opposite ends of the two locking members 50, forcing the two locking members 50 to move in opposite directions. The two locking members 50 push the two guide rods 520 to move in opposite directions, forcing the two top springs 511 to compress and store force. At the same time, the reinforcing bar 310 falls into the locking space 510 between the two locking members 50. The top springs 511 release their elastic force in the opposite direction, and apply the elastic force to the locking members 50, making the locking space 510 narrower while locking and fixing the reinforcing bar 310 to prevent the lifting member 30 from moving automatically. The second connecting hole 2201 is actually the screw hole inherent in the second chain piece 220. In this invention, the second connecting hole 2201 is applied to the mounting top block 51 to avoid secondary processing of the hinge 20 as much as possible. However, the second connecting hole 2201 can be slightly enlarged to a square (or polygonal) shape. The shape of the buckle 512 is consistent with the shape of the second connecting hole 2201. When the buckle 512 is fastened to the second connecting hole 2201 to install the top block 51, it can prevent the top block 51 from rotating and ensure that the top block 51 positions the lock 50 on the same straight line.

[0034] The bottom end of the hanger 30 is provided with a connecting part 301, which can be an external thread opened at the bottom end of the hanger 30 for hanging building structures or lighting products.

[0035] like Figure 8As shown, the present invention constructs a steel structure building by using the above-mentioned prefabricated steel structure ceiling structure, which is assembled by the following steps: Several I-beams 10 are used, and a first long groove 101 is opened inside the I-beams 10 along the length of the web; according to the construction location and the ceiling requirements of the suspended components on site, the two ends of the several I-beams 10 are welded to form a polygonal frame building skeleton; during welding, the welded ends of the I-beams 10 are cut, ground, and burrs are removed to avoid interference; multiple hinges 20 are selected, and the positions of the first connecting hole 2101 and the second connecting hole 2201 on the selected hinges 20 are determined accordingly. Set up a quick-release plate 40 and a quick-release assembly, and set a protrusion 410 on the bottom surface of the quick-release plate 40 corresponding to the first connecting hole 2101, and set a fastener 512 on the bottom surface of the top block 51 of the quick-release assembly corresponding to the second connecting hole 2201; select an appropriate number of hanging parts 30 according to the construction location and the ceiling requirements of the hanging parts on site, and suspend the hanging parts 30 one by one on the I-beam 10 through the hinge 20, and lock the position through the quick-release assembly and quick-release plate 40 so that all the hanging parts 30 form an array on the I-beam 10, and finally use the connecting part 301 at the bottom of the hanging part 30 to complete the ceiling suspension of the object.
