Description

Technical Field

[0001] The present invention relates to the technical field of steel structure buildings, and in particular to an assembled steel structure building ceiling structure and a steel structure building. Background Art

[0002] With the development of building industrialization, prefabricated steel structures have gained widespread application in large factories, stadiums, and multi-story buildings due to their advantages, such as fast construction and highly standardized components. In these buildings, ceiling systems serve as crucial space dividers and decorative elements, and their installation efficiency directly impacts the overall construction schedule. Traditional steel building ceilings are often secured to I-beams using welding or bolting to meet load-bearing and positioning requirements.

[0003] However, these traditional installation methods have the following drawbacks: The bolted or welded connections between the hangers and the I-beams are difficult to adjust once secured, resulting in low assembly efficiency and a high risk of component damage. Furthermore, these methods require high levels of professional skill from the installers, increasing labor costs and training difficulties. Therefore, there is an urgent need to develop a connection structure that allows for fast, flexible, and tool-free installation between the hangers and the I-beams, significantly improving the construction efficiency of prefabricated steel structures. Summary of the Invention

[0004] In order to solve the above problems, the present invention provides the following technical solutions: The cam is fastened to the top of the hinged member so that the hinged member can be fastened to the top of the hinged member and the hinged member can be fastened to the top of the hinged member so that the hinged member can be fastened to the top of the hinged member.

[0005] As a further preference, the first long slot is a rectangular slot opened along the length direction of the inner cavity structure portion of the I-beam, and a hanging array consisting of a plurality of combination pages and a plurality of hanging parts is provided along the length direction of the first long slot.

[0006] As a further preference, the quick-release assembly also includes a quick-release plate arranged in the I-beam, the quick-release plate is only pressed on the first chain plate of all the hinges, and the outer edges of both sides of the quick-release plate are spot welded to the inner walls of both sides of the I-beam.

[0007] As a further preferred embodiment, a protrusion is provided on the bottom surface of the quick-release plate, and the protrusion is buckled into the first connecting hole on the first chain piece of the hinge.

[0008] As a further preferred embodiment, a second long slot is provided in the middle of the quick-release plate, and the second long slot is located above the second chain plate. When the second chain plate rotates upward, it can pass through the second long slot and reach the top of the quick-release plate.

[0009] As a further preferred embodiment, the quick-release assembly also includes a lock and a top block. Two locks are sliding on the top surface of the same second chain plate, and a locking space is left between the two locks on the same second chain plate. Two top blocks are provided on the same second chain plate, and the two top blocks are respectively located on the outside of the lock. A guide rod is installed on the side of the lock facing the top block, and a top spring is filled in the top block. The top spring is sleeved on the guide rod, and the guide rod passes through the top block and is slidably assembled on the top block. A buckle seat is fixed on the bottom surface of the top block, and the buckle seat is buckled in the second connecting hole of the second chain plate. The opposite ends of the two locks on the same second chain plate are provided with rounded surfaces.

[0010] As a further preference, a connecting portion is provided at the bottom end of the hanging piece.

[0011] A steel structure building is assembled by the following steps: a plurality of I-beams are provided with a first long groove along the length direction of the web, and the two ends of the plurality of I-beams are welded to form a polygonal frame building skeleton, the plurality of I-beams are connected, a quick-release plate and a quick-release assembly are arranged according to the original positions of the first connection hole and the second connection hole, a protrusion corresponding to the first connection hole is provided on the bottom surface of the quick-release plate, and a buckle seat corresponding to the second connection hole is provided on the bottom surface of the top block of the quick-release assembly, a suitable number of hanging parts are selected, and the hanging parts are hung one by one on the I-beams through hinges, and the positions are locked by the quick-release assembly and the quick-release plate so that all the hanging parts are arranged in an array on the I-beams, and finally the objects are suspended from the ceiling using the connection parts at the bottom ends of the hanging parts.

[0012] The beneficial effects of the present invention compared to the prior art are: The core advantage lies in the "tool-free, twist-and-lock" installation of the hanger. Installation requires only two simple steps: "insert and twist," eliminating tedious welding and bolting processes. Installing a hanger takes only seconds, resulting in highly efficient assembly and significantly shortening the overall construction cycle of the ceiling system. The hinges are standard, readily available components, eliminating the need for custom molds. This makes procurement easy and cost-effective, significantly reducing the material cost of the entire connection structure and fully utilizing standard components. The top surface of the hinge chain supports the welded rebar, providing a stable and reliable bearing point. Once the hanger is rotated into position, it self-locks, preventing displacement or loosening. The large contact surface between the rebar and the two chains ensures uniform force distribution. The first long slot in the I-beam allows the hinge assembly to be adjusted along its length before or during initial installation, facilitating precise positioning of the hanger point according to the ceiling design. To adjust or replace the hanger, simply rotate the hanger in the opposite direction to align the top rebar with the hinge chain, and then remove it downwards. This operation is equally simple and quick, providing greater flexibility. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0015] The above and other embodiments and advantages of the present invention are clearly and completely described below in conjunction with the accompanying drawings. Obviously, the embodiments described are only some embodiments of the present invention, not all embodiments.

[0016] In one embodiment, Figures 1-8 As shown: The present embodiment provides an assembled steel building ceiling structure, including an I-beam 10 and a quick-install assembly, the quick-install assembly including a hinge 20 arranged in the I-beam 10, a hanger 30 quickly assembled on the I-beam 10 through the hinge 20, a first long slot 101 is opened in the I-beam 10, two hinges 20 are arranged at the same position of the first long slot 101, the first chain pieces 210 of the two hinges 20 are located on one side of the first long slot 101 and close to the inner wall of the I-beam 10 and fixed, the second chain pieces 220 of the two hinges 20 extend toward the first long slot 101 And they are adjacent to each other, and the adjacent ends of the two second chain pieces 220 of the two hinges 20 are respectively provided with arc-shaped openings 230, and the two arc-shaped openings 230 together constitute 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, and the top end of the hanger 30 passes through the first long groove 101 and the circular through hole 240 and penetrates into the I-beam 10, and a steel bar 310 is welded at the top end of the hanger 30 for quick hanging on the top surface of the two second chain pieces 220, and the diameter of the steel bar 310 is smaller than the distance between the two second chain pieces 220.

[0017] The core of the prefabricated steel building ceiling structure of the present invention lies in the ingenious use of the articulated properties of standard hinges and the internal space of the I-beam 10 to achieve rapid positioning and reliable suspension of the hanger 30. The specific working principle is as follows: a first long slot 101 is provided on the inner side of the web of the I-beam 10, which provides space for the horizontal installation position of the hinge 20. Two standard hinges 20 are placed parallel to the first long slot 101 at the same position on the web, so that their first chain links 210 are respectively fixed to the inner wall of the I-beam 10 on both sides, and their second chain links 220 extend into the first long slot 101 and move toward the centerline of the first long slot 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, the two arc-shaped openings 230 are close to a circle and together form a circular through hole 240 located directly above the first long slot 101. The bottom end of the hanger 30 is located below the I-beam 10, and the top end of the hanger 30 passes through the first long slot 101 and the circular through hole 240 in sequence and extends into the interior of the I-beam 10. Before the hanger 30 extends into the I-beam 10, the steel bar 310 at the top end of the hanger 30 is horizontally pressed between the two second chain pieces 220. The hanger 30 is pushed upward with force, so that the steel bar 310 simultaneously presses against the two second chain pieces 220 and rotates upward, so that the steel bar 310 passes through the first long slot 101 and enters the I-beam 10. The hanger 30 is rotated, and the steel bar 310 is driven by the hanger 30 to rotate, so that the steel bar 310 is pressed against the second chain pieces 220. Figure 4 The shape shown is securely hooked onto the top surface of the second chain pieces 220 of the hinges 20 on both sides. At this point, the steel bar 310 is supported by the two second chain pieces 220, and the weight of the hanger 30 is evenly transferred through the steel bar 310 to the two second chain pieces 220, and then to the I-beam 10 body through the first chain piece 210. This allows for fast and stable hanging and positioning of the hanger 30, resulting in high assembly efficiency, less risk of component damage, and lower requirements for the professional skills of the installers, reducing labor costs and training difficulties.

[0018] On the one hand, the first long groove 101 provides an adjustment margin for the initial installation positioning of the hinge 20, allowing the position of the hanging point to be flexibly set within a certain range according to the design requirements; on the other hand, the length direction dimension of the first long groove 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 steel bar. According to the requirements of the building ceiling, it is often necessary to hang several hangers 30 on the same I-beam 10. In addition to the long distance setting of the first long groove 101, multiple circular hangers are also set at multiple positions of the first long groove 101 in the above manner. The through hole 240 and the corresponding multiple combination pages 20, that is, a hanging array consisting of a plurality of combination pages 20 and a plurality of hangers 30 is provided along the length direction of the first long groove 101, for quickly hanging a plurality of hangers 30; on the contrary, since the diameter of the steel bar 310 is smaller than the distance between the two second chain plates 220, the hanger 30 is driven to adjust the steel bar 310 to the opposite end of the two second chain plates 220 by rotating the hanger 30 in the opposite direction, and then the hanger 30 can be removed downward by pulling it down, and then the hanging position of the hanger 30 can be adjusted by the same assembly method, which makes it more flexible to use. The design of the circular through hole 240 formed by the arc-shaped opening 230 ensures that the hanger 30 is not obstructed during the passage and rotation process. The technical requirements of the arc-shaped opening 230 are: the edge of the circular hole is smooth without sharp corners, burrs or fins, so as to smoothly guide the hanger 30 to drive the steel bar 310 to rotate to the locked position and rotate 90 degrees perpendicular to the inner wall of the I-beam 10, thereby reducing friction. The rotatability of the hinge 20 is utilized to improve the assembly efficiency when assembling the hanger 30. The hinge 20 itself is an assembly part and can be applied to the roof structure after slight modification before assembly, thereby further saving costs.

[0019] The quick-release assembly also includes a quick-release plate 40 positioned within the I-beam 10. The quick-release plate 40 presses only against the first link 210 of all hinges 20, and its outer edges are spot-welded to the inner walls of the I-beam 10. The quick-release plate 40 acts as a covering layer, compressing the first link 210 of all hinges 20, restricting their movement. It also uses the first link 210 to lock the free end of the second link 220, which is hinged to it, on the axis of the first slot 101. If multiple hinges 20 are used, the quick-release plate 40 quickly applies pressure to assemble them, improving assembly efficiency.

[0020] A protrusion 410 is provided on the bottom surface of the quick-release plate 40. This protrusion 410 snaps into the first connecting hole 2101 on the first link 210 of the hinge 20. The clearance fit (H9 / h8) between the first connecting hole 2101 and the protrusion 410 allows for fine-tuning, but limits horizontal displacement while facilitating snap-fit ​​and press-fit. The snap-fit ​​action of the quick-release plate 40 positions the first link 210 of the hinge 20 within the I-beam 10. The quick positioning of the first link 210 secures the entire hinge 20 within the I-beam 10, improving assembly efficiency. The first connecting hole 2101 is actually a screw hole inherent in the first link 210. In the present invention, the first connecting hole 2101 is used to quickly position the quick-release plate 40, minimizing secondary processing of the hinge 20.

[0021] A second long slot 420 is defined in the middle of the quick-release plate 40 and is located above the second chain link 220. When the second chain link 220 rotates upward, it passes through the second long slot 420 and reaches above the quick-release plate 40. When the second chain link 220, pulled upward by the steel bar 310, rotates upward, the hinged end of the second chain link 220 moves in an arc and passes through the second long slot 420 to quickly suspend the quick-release plate 40.

[0022] The quick-release assembly also includes a lock 50 and a top block 51. Two locks 50 are sliding on the top surface of the same second chain piece 220. A locking space 510 is left between the two locks 50 on the same second chain piece 220. Two top blocks 51 are provided on the same second chain piece 220. The two top blocks 51 are respectively located on the outside of the lock 50. A guide rod 520 is installed on the side of the lock 50 facing the top block 51. The top block 51 is filled with a top spring 511, and 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 seat 512 is fixed on the bottom surface of the top block 51, and the buckle seat 512 is buckled in the second connecting hole 2201 of the second chain piece 220. The opposite ends of the two locks 50 on the same second chain piece 220 are provided with rounded surfaces 2202.

[0023] The buckle seat 512 is inserted into the second connecting hole 2201 of the second chain piece 220 to fix the top block 51, so that the top spring 511 at the other end of the top block 51 is sleeved on the guide rod 520, and the guide rod 520 is fixed on the lock 50. Two locks 50 are set on the same second chain piece 220 in the same way, and a locking space 510 is formed between the two locks 50. After rotating 90 degrees, the steel bar 310 falls exactly between the two locks 50. Pull down the hanger 30 with force, and the hanger 30 drags the steel bar downward with force. 310, the outer cylindrical surface of the steel bar 310 and the rounded surfaces 2202 at the opposite ends of the two locking pieces 50 are crushed, forcing the two locking pieces 50 to move in the opposite direction. The two locking pieces 50 push the two guide rods 520 to move in the opposite direction, forcing the two top springs 511 to compress and store force. At the same time, the steel bar 310 falls into the locking space 510 between the two locking pieces 50, and the top spring 511 releases the elastic force in the reverse direction, and applies the elastic force to the locking piece 50, thereby narrowing the locking space 510 and locking the steel bar 310 to prevent the hanger 30 from moving automatically. The second connecting hole 2201 is actually a screw hole inherent in the second chain plate 220. In the present invention, the second connecting hole 2201 is applied to the installation top block 51 to avoid the hinge 20 from being processed twice 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 seat 512 is consistent with the shape of the second connecting hole 2201. When the buckle seat 512 is buckled into the second connecting hole 2201 to install the top block 51, it can prevent the top block 51 from rotating, ensuring that the top block 51 positions the lock 50 on the same straight line.

[0024] The bottom end of the hanger 30 is provided with a connecting portion 301 , which may be an external thread provided at the bottom end of the hanger 30 for hanging building structures or lighting products.

A quick-release plate 40 and a quick-release assembly are provided, and a protrusion 410 corresponding to the first connection hole 2101 is provided on the bottom surface of the quick-release plate 40, and a buckle seat 512 corresponding to the second connection hole 2201 is provided on the bottom surface of the top block 51 of the quick-release assembly; according to the construction location and the ceiling requirements of the on-site hanging parts, a suitable number of hangers 30 are selected, and the hangers 30 are hung one by one on the I-beam 10 through the hinges 20, and the positions are locked by the quick-release assembly and the quick-release plate 40 so that all the hangers 30 are arranged in an array on the I-beam 10, and finally the connection part 301 at the bottom end of the hanger 30 is used to complete the ceiling suspension of the object.
