Description

Technical Field

[0001] This utility model relates to the field of steel structure roofing technology, specifically to a steel structure roof with an integrated grid structure. Background Technology

[0002] A steel structure roof is a roofing system that uses steel as the primary structural material. It consists of steel beams, steel columns, steel plates, and connectors (such as purlins), assembled through welding, bolting, or riveting. Steel structure roofs are typically used in large-span, large-space buildings, such as industrial plants, commercial buildings, and stadiums.

[0003] A steel structure roof with an integrated grid structure, disclosed in announcement number CN220285131U, includes a roof frame main body. Baffles are fixedly connected to both sides of the exterior of the roof frame main body. Several sets of second support frames are arranged horizontally inside the roof frame main body, and several sets of first support frames are arranged vertically inside the roof frame main body. This integrated grid structure steel structure roof optimizes the overall structural flexibility by incorporating connecting seats, mounting blocks, limiting protrusions, snap-fit ​​grooves, and limiting fixing plates. This facilitates targeted disassembly and replacement of damaged parts in the structure, reducing maintenance costs. It addresses the problems of an integrated structure where quick disassembly and replacement are difficult when the roof structure malfunctions, resulting in low structural flexibility. Structures with easy disassembly cannot provide strong support and are prone to collapse after prolonged use. It also addresses the incompatibility between installation / disassembly and stabilization.

[0004] Similar to the existing technologies described above, the following shortcomings also exist: During installation and use, existing steel structure roofs lack a fixed structure at the connection between the support frame and the frame, making the connection prone to loosening. This allows the support frame to move vertically, affecting the stability of the steel structure roof. Especially in large-span spaces, under external forces such as wind loads, snow loads, or earthquakes, the support frame may shift or tilt, leading to instability of the entire roof structure. For example, in 2019, a factory in China experienced a roof collapse after a heavy snowfall due to insufficiently secure connections between the support frame and the frame. Summary of the Invention

[0005] The purpose of this invention is to provide a steel structure roof with an integrated grid structure to solve the problem in the prior art where the support frame is prone to vertical movement due to the lack of a fixing mechanism between the support frame and the frame, which affects the stability of the steel structure roof.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a steel structure roof with an integrated grid structure, including a support mechanism, and further comprising:

[0007] A fixing mechanism, located on the outside of the support mechanism, is used to fix the support mechanism in place;

[0008] Multiple connecting mechanisms are provided and are respectively located around the inner wall of the fixing mechanism, for connecting and fixing the supporting mechanism and the fixing mechanism;

[0009] The fixing mechanism includes a fixing frame, which is disposed on the outside of the support mechanism;

[0010] The connecting mechanism includes a fixed seat for supporting the installation of the mechanism. Multiple fixed seats are respectively fixedly installed around the inner wall of the fixed frame. The fixed seat is configured as a U-shaped structure. A cover plate is rotatably installed at one end of the top of the fixed seat. A fastening pin is provided between the fixed seat and the cover plate.

[0011] Preferably, the fixing mechanism includes two first connecting plates and two second connecting plates. The two first connecting plates are respectively fixedly installed on both sides of the outer wall of one end of the fixing frame. The outer wall of the fixing frame away from the first connecting plates is provided with first connecting grooves on both sides.

[0012] Preferably, the two second connecting plates are respectively fixedly installed at both ends of one side of the outer wall of the fixing frame, and the two ends of the outer wall of the fixing frame away from the second connecting plates are provided with second connecting grooves, and the top of the outer wall of one end of the fixing seat is provided with a fixing groove.

[0013] Preferably, a plug plate is fixedly installed at the bottom of the end of the cover plate away from the fixed seat, which is movably connected to the inner wall of the adjacent fixed groove. The inner wall of the plug plate is threadedly connected to the outer wall of the fastening pin, and the end of the fastening pin away from the plug plate is threadedly connected to the inner wall of the fixed groove.

[0014] Preferably, the support mechanism includes two first support frames and three second support frames. The two first support frames are parallel to the direction of the first connecting plate, and the three second support frames are parallel to the direction of the second connecting plate. The two ends of the first support frames and the two sides of the second support frames are respectively movably connected to the inner wall of the adjacent fixed seat.

[0015] Preferably, the two first support frames and the three second support frames are connected by a mortise and tenon structure. A connecting seat is movably fitted at the intersection of the first support frame and the second support frame. A connecting bolt is provided between the connection position of the first support frame and the second support frame and the adjacent connecting seat, and the connection is fixed by the connecting bolt.

[0016] The beneficial effects provided by this utility model are as follows: the fixing seat can support and place the first and second support frames; the connection between the plug-in plate and the fixing groove allows the cover plate to seal the top opening of the fixing seat; the fastening pin passes through the plug-in plate and is threaded to the inner wall of the fixing groove to fix the cover plate, thereby ensuring that the fixing seat and the cover plate can stably fix the first and second support frames, preventing the first and second support frames from moving in the vertical direction, thus ensuring the stability of the steel structure roof. The connection between the first connecting plate and the adjacent first connecting groove, and the connection between the second connecting plate and the adjacent second connecting groove, allows the two connected fixing frames to be easily spliced ​​at different positions in the horizontal direction, making the splicing of steel structure roof components more convenient. At the same time, the mortise and tenon structure connection ensures a tight connection between the first and second support frames, and the connection between the first and second support frames can be reinforced by connecting bolts and connecting seats.

[0027] 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 of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0028] This utility model embodiment provides, as follows: Figure 1-5 The steel roof structure with an integrated grid structure shown includes support mechanism 3, and also includes:

[0029] The fixing mechanism 1 is located on the outside of the support mechanism 3 and is used to fix the support mechanism 3.

[0030] The connecting mechanism 2 is provided in multiple parts and is respectively arranged around the inner wall of the fixing mechanism 1, and is used to connect and fix the supporting mechanism 3 and the fixing mechanism 1.

[0031] The fixing mechanism 1 includes a fixing frame 101, which is located on the outside of the support mechanism 3. The fixing frame 101 can install and fix the support mechanism 3, so that the support mechanism 3 can remain stable inside the fixing frame 101.

[0032] The connecting mechanism 2 includes a fixing seat 201 for mounting the support mechanism 3. Multiple fixing seats 201 are fixedly installed around the inner wall of the fixing frame 101. The fixing seat 201 is U-shaped. A cover plate 203 is rotatably installed at one end of the top of the fixing seat 201. A fastening pin 205 is provided between the fixing seat 201 and the cover plate 203. The fixing seat 201 and the cover plate 203 can place and fix the support mechanism 3, so that the support mechanism 3 remains stable inside the fixing frame 101.

[0033] To facilitate the easy splicing of adjacent fixed frames 101, the fixing mechanism 1 includes two first connecting plates 102 and two second connecting plates 104. The two first connecting plates 102 are respectively fixedly installed on both sides of the outer wall of one end of the fixed frame 101. The outer wall of the fixed frame 101 away from the first connecting plates 102 is provided with first connecting grooves 103 on both sides. The two second connecting plates 104 are respectively fixedly installed on both ends of the outer wall of one side of the fixed frame 101. The outer wall of the fixed frame 101 away from the second connecting plates 104 is provided with second connecting grooves 105 on both ends. The top of the outer wall of one end of the fixing seat 201 is provided with a fixing groove 202. The connection between the first connecting plate 102 and the adjacent first connecting groove 103 allows the fixed frame 101 to be spliced ​​horizontally. The connection between the second connecting plate 104 and the adjacent second connecting groove 105 allows the fixed frame 101 to be spliced ​​vertically.

[0034] A plug-in plate 204, which is movably connected to the inner wall of the adjacent fixing groove 202, is fixedly installed at the bottom of the cover plate 203 away from the fixing seat 201. The inner wall of the plug-in plate 204 is threadedly connected to the outer wall of the fastening pin 205. The end of the fastening pin 205 away from the plug-in plate 204 is threadedly connected to the inner wall of the fixing groove 202. The connection between the fixing groove 202 and the plug-in plate 204 allows the cover plate 203 to seal the top opening of the fixing seat 201. The fastening pin 205 connects the plug-in plate 204 and the fixing groove 202, so that the first support frame 301 and the second support frame 302 can remain stable in the vertical direction. The plug-in plate 204 is not tightly attached to the fixing groove 202, but has a certain amount of clearance, so that the plug-in plate 204 can be opened through the part where the fixing seat 201 and the cover plate 203 are rotatably connected.

[0035] like Figure 5 As shown, the support mechanism 3 includes a first support frame 301 and a second support frame 302 that are perpendicular to each other. In this embodiment, it includes two first support frames 301 and three second support frames 302. The directions of the two first support frames 301 are parallel to the direction of the first connecting plate 102, and the directions of the three second support frames 302 are parallel to the direction of the second connecting plate 104. The two ends of the first support frame 301 and the two sides of the second support frame 302 are respectively movably connected to the inner wall of the adjacent fixed seat 201. The fixed frame 101 can install and fix the first support frame 301 and the second support frame 302.

[0036] Specifically, such as Figure 2 , 5As shown, two first support frames 301 and three second support frames 302 are connected by a mortise and tenon structure. A connecting seat 303 is movably fitted at the intersection of the first support frame 301 and the second support frame 302. The connecting seat 303 has protrusions that are vertically upward at the four corners. Connecting bolts 304 are provided between the connection position of the first support frame 301 and the second support frame 302 and between adjacent connecting seats 303, and the connection is fixed by the connecting bolts 304. The connecting seat 303 can fix the connection position between the first support frame 301 and the second support frame 302. The connecting bolts 304 pass through the first support frame 301 and the second support frame 302 and are threaded to the inner wall of the connecting seat 303, making the connection between the first support frame 301 and the second support frame 302 more secure.

[0037] The process of using this utility model is as follows: First, place the two ends of multiple first support frames 301 on the inner sides of two horizontally opposite fixed seats 201 respectively. Then, place the two sides of multiple second support frames 302 on the inner sides of two vertically opposite fixed seats 201 respectively, so that the first support frames 301 and the second support frames 302 can be connected by a mortise and tenon structure. Then, the connecting seat 303 is sleeved on the outer side of the connection position of the first support frame 301 and the second support frame 302. The connecting bolt 304 is used to penetrate the inner wall of the first support frame 301 and the second support frame 302 and is threadedly connected to the inner wall of the connecting seat 303, so that the first support frame 301 and the second support frame 302 are tightly connected. Then, by rotating the cover plate 203 from a vertical to a horizontal position, the insertion plate 204 is inserted into the inner wall of the adjacent fixing groove 202. The cover plate 203 can seal the top opening of the fixing seat 201. Then, a fastening pin 205 is used to pass through the insertion plate 204 and threadedly connect to the inner wall of the fixing groove 202. The first support frame 301 and the second support frame 302 can be placed and fixed through the fixing seat 201 and the cover plate 203, preventing the first support frame 301 and the second support frame 302 from moving in the vertical direction, making the steel structure roof more stable. The connection between the first connecting plate 102 and the adjacent first connecting groove 103 allows the fixing frame 101 to be spliced ​​horizontally, and the connection between the second connecting plate 104 and the adjacent second connecting groove 105 allows the fixing frame 101 to be spliced ​​vertically. Workers can easily splice the steel roof structure in different directions. This embodiment specifically solves the problem in the prior art that the lack of a fixing structure between the support frame and the frame makes it easy for vertical movement to occur, which affects the stability of the steel structure roof.
