Description

Technical Field

[0001] The invention relates to the technical field of building engineering, and in particular to a fixed connection structure. Background Art

[0002] The steel plate formed by cold bending the coated plate or plated plate by rollers to form a corrugated cross section along the width of the plate is called a corrugated steel plate. Corrugated steel plates are widely used in engineering, but corrugated steel plates are generally narrow in width. In actual construction, multiple corrugated steel plates need to be spliced ​​into a larger plate. The traditional splicing method is too simple, making the spliced ​​corrugated steel plates not firmly connected.

[0003] In order to solve the above problems of the traditional splicing method, the relevant document CN213741940U discloses a fixed connection structure of corrugated steel plates for construction engineering. By setting multiple fixing mechanisms, it not only realizes the fixation of two corrugated steel plates, but also has multiple fixing points, so that the two corrugated steel plates can be tightly fixed. Although the above-mentioned related document improves the connection strength of the two corrugated steel plates compared with the traditional splicing method, it still has the following shortcomings in actual use: the strength of the connection point of the corrugated steel plates is low after being connected, and the connection is easy to bend and produce gaps after being stressed, which has an adverse effect on actual use. Summary of the invention

[0051] Combine the following Figures 1 to 6 , describing an embodiment of the present invention.

[0052] According to an embodiment of the present invention, a fixed connection structure is provided for connecting two corrugated steel plates 100. The two corrugated steel plates 100 are provided with a first inclined portion 110 and a second inclined portion 120 at one end facing each other. The first inclined portion 110 and the second inclined portion 120 are provided with a horizontal portion 130 at one end facing each other. The fixed connection structure includes a first connecting component and a second connecting component that are separately arranged. The first connecting component includes a bottom plate 210 and a first plate 220 and a second plate 230 that are folded and arranged on both sides of the bottom plate 210 along the length direction of the bottom plate 210. The bottom plate 210 is arranged abutting against the horizontal portion 130. The bottom end surface of the horizontal portion 130, the first plate 220 and the second plate 230 respectively abut against the side surfaces of the first inclined portion 110 and the second inclined portion 120 which are away from each other; the second connecting component includes a top plate 310 and a third plate 320 and a fourth plate 330 folded along the length direction of the bottom plate 210 and arranged on both sides of the top plate 310, the top plate 310 abuts against the top end surface of the horizontal portion 130, the third plate 320 and the fourth plate 330 respectively abut against the side surfaces of the first inclined portion 110 and the second inclined portion 120 which are facing each other; the first connecting component and the second connecting component are locked by a locking mechanism.

[0053] The fixed connection structure of this embodiment is provided with a first plate 220 and a second plate 230 respectively folded on both sides of the bottom plate 210 along the length direction of the bottom plate 210, and a third plate 320 and a fourth plate 330 are respectively folded on both sides of the top plate 310 along the length direction of the bottom plate 210, and the first connection component and the second connection component are locked and connected into one by a locking mechanism, so that the bottom plate 210 and the top plate 310 are respectively abutted against the bottom end surface and the top end surface of the two horizontal parts 130, and the first plate 220 and the third plate 320 are respectively abutted against the bottom end surface and the top end surface of the two horizontal parts 130, and the first plate 220 and the third plate 320 are respectively abutted against the bottom end surface and the top end surface of the two horizontal parts 130. While respectively abutting against the two side surfaces of the first inclined portion 110 along the length direction of the bottom plate 210, the second plate 230 and the fourth plate 330 respectively abut against the two side surfaces of the second inclined portion 120 along the length direction of the bottom plate 210, so that the extruded fixed connection area is larger and the fixing form is more stable, thereby achieving effective resistance to the bending force exerted on the corrugated steel plate 100 during use on the basis of connecting and fixing the two corrugated steel plates 100, avoiding bending, gaps or even damage at the connection, and increasing the stability and safety of the connection.

[0054] It should be noted that because the bottom plate 210 and the top plate 310 are respectively abutted against the bottom end surface and the top end surface of each horizontal portion 130, and the first plate 220 and the third plate 320 are respectively abutted against the two side surfaces of the first inclined portion 110 along the length direction of the bottom plate 210, the extruded fixed connection area is larger, so the bending at the connection between the first inclined portion 110 and the horizontal portion 130 can be effectively avoided.

[0055] It should be noted that because the bottom plate 210 and the top plate 310 are respectively abutted against the bottom end surface and the top end surface of each horizontal portion 130, and the second plate 230 and the fourth plate 330 are respectively abutted against the two side surfaces of the second inclined portion 120 along the length direction of the bottom plate 210, the extruded fixed connection area is larger, so the bending at the connection between the second inclined portion 120 and the horizontal portion 130 can be effectively avoided.

[0056] It should be noted that the first plate 220 and the first inclined portion 110 are arranged in parallel, and the bottom plate 210 and the horizontal portion 130 are arranged in parallel, so that the angle formed between the first plate 220 and the bottom plate 210 is equal to the angle formed between the first inclined portion 110 and the horizontal portion 130; the second plate 230 and the second inclined portion 120 are arranged in parallel, and the bottom plate 210 and the horizontal portion 130 are arranged in parallel, so that the angle formed between the second plate 230 and the bottom plate 210 is equal to the angle formed between the second inclined portion 120 and the horizontal portion 130. The third plate 320 and the first inclined portion 110 are arranged in parallel, and the top plate 310 and the horizontal portion 130 are arranged in parallel, so that the angle formed between the third plate 320 and the top plate 310 is equal to the angle formed between the first inclined portion 110 and the horizontal portion 130; the fourth plate 330 and the second inclined portion 120 are arranged in parallel, and the top plate 310 and the horizontal portion 130 are arranged in parallel, so that the angle formed between the fourth plate 330 and the top plate 310 is equal to the angle formed between the second inclined portion 120 and the horizontal portion 130.

[0057] It can be understood that the arrangement direction of the horizontal portion 130 is parallel to the length direction of the bottom plate 210. The length direction of the bottom plate 210 is any direction on the horizontal plane. Figure 1 The first direction shown in FIG. 2 is described as the length direction of the bottom plate 210 , but it should not be understood as a clear limitation on the length direction of the bottom plate 210 .

[0058] like Figure 3 and Figure 4As shown, in some embodiments, the first plate 220, the first inclined portion 110 and the third plate 320 are provided with a first through hole 111 along the length direction of the base plate 210, and a first threaded tube 341 is provided at one end of the third plate 320 relatively away from the first inclined portion 110, and the internal threaded hole of the first threaded tube 341 is coaxially arranged with the first through hole 111, and the locking mechanism includes a first locking bolt 410 matching the internal threaded hole of the first threaded tube 341. In the process of connecting the two corrugated steel sheets 100, first align the two horizontal portions 130, then abut the bottom plate 210 against the bottom end surfaces of the two horizontal portions 130, and make the first plate 220 and the second plate 230 abut against the sides of the first inclined portion 110 and the second inclined portion 120 facing away from each other, then abut the top plate 310 against the top end surfaces of the two horizontal portions 130, and make the third plate 320 and the fourth plate 330 abut against the sides of the first inclined portion 110 and the second inclined portion 120 facing each other, at this time, the internal threaded hole of the first threaded tube 341 and the first through hole 111 are located on the same straight line along the first direction, finally, pass the rod of the first locking bolt 410 through the first through hole 111 and screw it into the internal threaded hole of the first threaded tube 341, so that the two corrugated steel sheets 100 can be connected and fixed into one.

[0059] like Figure 3 and Figure 4As shown, specifically, the second plate 230, the second inclined portion 120 and the fourth plate 330 are provided with a second through hole 121 along the length direction of the base plate 210, and the fourth plate 330 is provided with a second threaded tube 351 at one end relatively away from the second inclined portion 120, and the internal threaded hole of the second threaded tube 351 is coaxially arranged with the second through hole 121, and the locking mechanism also includes a second locking bolt 420 matching the internal threaded hole of the second threaded tube 351. After the third plate 320 and the fourth plate 330 are abutted against the sides of the first inclined portion 110 and the second inclined portion 120 facing each other, the internal threaded hole of the first threaded tube 341 and the first through hole 111 are located on the same straight line along the first direction, and the internal threaded hole of the second threaded tube 351 and the second through hole 121 are located on the same straight line along the first direction, and then the rod of the first locking bolt 410 is passed through the first through hole 111 and screwed into the internal threaded hole of the first threaded tube 341, and the rod of the second locking bolt 420 is passed through The second through hole 121 is threadedly screwed into the internal threaded hole of the second threaded tube 351, so that the first plate 220, the first inclined portion 110 and the third plate 320 are locked and connected as one, and the second plate 230, the second inclined portion 120 and the fourth plate 330 are locked and connected as one, thereby making the fixing form of connecting the two corrugated steel plates 100 more stable, and thus more effectively resisting the bending force applied to the corrugated steel plates 100 during use, avoiding bending, gaps or even damage at the connection, and increasing the stability and safety of the connection.

[0060] In a specific application, the first threaded tube 341 and the second threaded tube 351 can be set as the same threaded tube or different threaded tubes, and the selection is made according to actual needs. In this embodiment, it is preferred that the first threaded tube 341 and the second threaded tube 351 are the same threaded tubes, and the first locking bolt 410 and the second locking bolt 420 can be set as the same bolts, reducing the types of bolts required.

By making the first part 211 and the second part 212 respectively slidable and adjustable along the first direction relative to the top plate 310, the size of the second connecting component along the first direction can be flexibly adjusted, which can not only improve the operational convenience of connecting the two corrugated steel sheets 100, but also be suitable for the situation where the spacing size along the first direction on the side where the first inclined part 110 and the second inclined part 120 are away from each other remains unchanged, while the spacing size along the first direction on the side where the first inclined part 110 and the second inclined part 120 are away from each other changes.

[0071] like Figures 1 to 4 as well as Figure 6As shown, in some embodiments, the first through hole 111 and the second through hole 121 are coaxially arranged, and a rotating shaft 430 is arranged at one end of the top plate 310 relatively away from the horizontal portion 130, and the rotating shaft 430 is arranged parallel to the length direction of the bottom plate 210 and is driven to rotate by a driving mechanism; the end of the rotating shaft 430 facing the first threaded tube 341 is arranged as a first double-threaded tube 431, and the external threaded portion of the first double-threaded tube 431 is threadedly screwed into the internal threaded hole of the first threaded tube 341, and the rod portion of the first locking bolt 410 is used to be threadedly tightened into the internal threaded hole of the first double-threaded tube 431; the end of the rotating shaft 430 facing the second threaded tube 351 is arranged as a second double-threaded tube 432, and the external threaded portion of the second double-threaded tube 432 is threadedly screwed into the internal threaded hole of the second threaded tube 351, and the rod portion of the second locking bolt 420 is used to be threadedly tightened into the internal threaded hole of the second double-threaded tube 432.Because the first portion 211 and the second portion 212 can both slide relative to the top plate 310 along the first direction, during the process of connecting the two corrugated steel sheets 100, when the top plate 310 is abutted against the top surfaces of the two horizontal portions 130, and the first double-threaded tube 431 and the second double-threaded tube 432 are driven by the driving mechanism to rotate forwardly along with the rotating shaft 430, the first portion 211 and the second portion 212 cannot rotate relative to the top plate 310 along with the rotating shaft 430, so that the first threaded tube 341 and the second threaded tube 351 move in a direction away from each other. , so that the first part 211 and the second part 212 move in a direction away from each other until the third plate 320 and the fourth plate 330 respectively abut against the mutually facing sides of the first inclined part 110 and the second inclined part 120, at which time the internal threaded hole of the first double threaded tube 431, the internal threaded hole of the first threaded tube 341 and the first through hole 111 are located on the same straight line along the first direction, and the internal threaded hole of the second double threaded tube 432, the internal threaded hole of the second threaded tube 351 and the second through hole 121 are located on the same straight line along the first direction, and finally the first locking The rod of the bolt 410 passes through the first through hole 111 and the internal threaded hole of the first threaded tube 341 in sequence and is screwed into the internal threaded hole of the first double threaded tube 431, and the rod of the second locking bolt 420 passes through the second through hole 121 and the internal threaded hole of the second threaded tube 351 and is screwed into the internal threaded hole of the second double threaded tube 432, so that the first plate 220, the first inclined portion 110 and the third plate 320 are locked and connected as one, and the second plate 230, the second inclined portion 120 and the fourth plate 330 are locked and connected as one, and in the first The third plate 320 and the fourth plate 330 are supported and connected by a coaxially arranged first threaded tube 341, a first double threaded tube 431, a rotating shaft 430, a second double threaded tube 432 and a second threaded tube 351, which can resist the first inclined portion 110 and the second inclined portion 120 from moving toward each other along the first direction, and can also resist the first inclined portion 110 and the second inclined portion 120 from moving away from each other along the first direction, thereby being more conducive to resisting bending caused by force and increasing the stability and safety of the connection.

[0072] It should be noted that when the driving mechanism drives the rotating shaft 430 to rotate forward, it drives the first threaded tube 341 and the second threaded tube 351 to move away from each other, and when the driving mechanism drives the rotating shaft 430 to rotate reversely, it drives the first threaded tube 341 and the second threaded tube 351 to move toward each other.

[0073] like Figure 3 and Figure 6As shown, specifically, the driving mechanism includes a worm wheel 441 coaxially arranged on the rotating shaft 430, the worm wheel 441 is meshed with a worm 442, the worm 442 is arranged at one end of the top plate 310 relatively away from the horizontal portion 130, and is driven to rotate by the power assembly. In the process of connecting the two corrugated steel sheets 100, the worm 442 is driven to rotate by the power assembly, so that the worm 442 drives the worm wheel 441 to rotate, so that the rotating shaft 430 rotates forward to drive the third plate 320 and the fourth plate 330 to move in a direction away from each other until they respectively abut against the sides of the first inclined portion 110 and the second inclined portion 120 facing each other, and cooperate with the first locking bolt 410 and the second locking bolt 420 to realize the connection and fixation of the two corrugated steel sheets 100 into one; at the same time, the worm 442 drives the worm 442 to realize the self-locking function, further increasing the stability and safety of the connection.

[0074] like Figure 6 As shown, specifically, two first support frames 450 are provided at one end of the top plate 310 relatively away from the horizontal portion 130, the two first support frames 450 are spaced apart along the first direction, the rotating shaft 430 is rotatably connected to the two first support frames 450, and the worm gear 441 is provided at the portion of the rotating shaft 430 located between the two first support frames 450.

[0075] like Figure 6 As shown, specifically, the power assembly includes a first bevel gear 443 coaxially connected to the worm 442, the first bevel gear 443 is meshed with a second bevel gear 444, the second bevel gear 444 is coaxially connected with a rotating rod 445, the rotating rod 445 is rotatably connected to one end of the top plate 310 relatively away from the horizontal portion 130, and a knob 446 is provided at one end of the rotating rod 445 relatively away from the top plate 310. By vertically arranging the rotating rod 445 and providing a knob 446 at the top of the rotating rod 445, it is convenient for an operator to hold the knob 446 and apply an external force to drive the rotating rod 445 to rotate, and the worm 442 is driven to rotate through the meshing transmission relationship between the first bevel gear 443 and the second bevel gear 444, so as to realize the positive rotation of the driving shaft 430 to drive the third plate 320 and the fourth plate 330 to move in a direction away from each other until they respectively abut against the sides of the first inclined portion 110 and the second inclined portion 120 facing each other.

[0076] like Figure 6 As shown, specifically, two second support frames 460 are provided at one end of the top plate 310 relatively far from the horizontal portion 130 . The two second support frames 460 are spaced apart along the length direction of the worm 442 , and the worm 442 is rotatably connected to the two second support frames 460 .

[0077] like Figures 1 to 5As shown, in some embodiments, a first extrusion plate 340 is arranged between the third plate 320 and the first threaded tube 341, and the end surface of the first threaded tube 341 relatively close to the third plate 320 is flush with the end surface of the first extrusion plate 340 relatively close to the third plate 320; a third movable slide rod 321 is arranged at one end of the third plate 320 relatively close to the first extrusion plate 340; a third slide hole 342 is arranged through the first extrusion plate 340 along the length direction of the bottom plate 210, and the third movable slide rod 321 is slidably arranged in the third slide hole 342. Through the guiding cooperation relationship between the third sliding hole 342 and the third movable sliding rod 321, the freedom of the first extrusion plate 340 to rotate around the first direction relative to the third plate 320 is restricted, so that when the first double-threaded tube 431 is driven by the driving mechanism to rotate forward together with the rotating shaft 430, the first threaded tube 341 drives the lighter first extrusion plate 340 to move in the direction away from the fourth plate 330, and then pushes the third plate 320 to move in the direction away from the fourth plate 330, which makes the operation more labor-saving.

[0078] Specifically, the projection area of ​​the first pressing plate 340 along the first direction is half of the projection area of ​​the third plate 320 along the first direction.

[0079] Specifically, a second extrusion plate 350 is arranged between the fourth plate 330 and the second threaded tube 351, and the end surface of the second threaded tube 351 relatively close to the fourth plate 330 is flush with the end surface of the second extrusion plate 350 relatively close to the fourth plate 330; a fourth movable slide bar 331 is arranged at one end of the fourth plate 330 relatively close to the second extrusion plate 350; a fourth sliding hole is arranged through the second extrusion plate 350 along the length direction of the bottom plate 210, and the fourth movable slide bar 331 is slidably arranged in the fourth sliding hole. Through the guiding matching relationship between the fourth sliding hole and the fourth movable slide bar 331, the freedom of the second extrusion plate 350 to rotate around the first direction relative to the fourth plate 330 is limited, so that when the second double threaded tube 432 is driven by the driving mechanism to rotate forwardly with the rotating shaft 430, the second threaded tube 351 drives the second extrusion plate 350 with a lighter weight to move in a direction away from the third plate 320, thereby pushing the fourth plate 330 to move in a direction away from the third plate 320, and the operation is more labor-saving.

[0080] Specifically, the projection area of ​​the second pressing plate 350 along the first direction is half of the projection area of ​​the fourth plate 330 along the first direction.

[0081] In some embodiments, the end surface of the bottom plate 210 facing the horizontal portion 130, the end surface of the top plate 310 facing the horizontal portion 130, the end surface of the first plate 220 facing the first inclined portion 110, the end surface of the third plate 320 facing the first inclined portion 110, the end surface of the second plate 230 facing the second inclined portion 120, and the end surface of the fourth plate 330 facing the second inclined portion 120 are all provided with anti-slip grooves. The provision of the above-mentioned anti-slip grooves can increase the friction between the first connecting component and the second connecting component and the corrugated steel plate 100, thereby helping to increase the stability of the connection.

[0082] Although the embodiments of the present invention have been described in conjunction with the accompanying drawings, those skilled in the art may make various modifications and variations without departing from the spirit and scope of the present invention, and such modifications and variations are all within the scope defined by the present invention.
