Description

Technical Field

[0001] This utility model relates to the field of steel structure building technology, specifically to a node connection device for multi-story prefabricated steel structure modular houses. Background Technology

[0002] Prefabricated buildings are a type of building constructed by assembling components manufactured in factories and transported to the construction site. The advantages of this type of building include fast construction speed, less susceptibility to weather conditions, labor saving, and improved building quality. The development of prefabricated buildings is a key link in the industrialization of construction and also the ultimate path and fundamental characteristic of industrialized buildings.

[0003] The publication number CN106522363A discloses a modular steel frame connection device, which includes at least a first and a second hollow square steel pipe column. The first and second square steel pipe columns are connected by an inner sleeve, with a clearance fit between the inner sleeve and the first and second square steel pipe columns. The outer circumference of the inner sleeve is provided with positioning blocks parallel to the column openings of the first and second square steel pipe columns. The device also includes a connecting plate with assembly holes that mate with the inner sleeve. The modular steel frames are connected via the inner sleeve, eliminating the need for screws or bolts, saving on-site construction steps and shortening construction time. Welding the modular steel frames to the inner sleeve enhances the strength of the frames, avoiding risks caused by loose screws or bolts. By pre-processing the modular steel frames in the factory before on-site construction, on-site construction time is significantly shortened, and the impact on the site environment is minimal.

[0004] During use, this device uses connecting plates to bring together modular steel frames that are connected laterally or centrally, making it easier to form a regular modular steel frame and improving its strength. However, in actual use, the dimensions of the connecting plates are fixed, and the construction precision of the square steel pipe columns is particularly important. Due to the large amount of work and the influence of factors such as terrain, the modular steel frames are prone to certain errors after installation. In this case, the connecting plates cannot effectively connect the modular steel frames, which has certain limitations.

[0005] Therefore, it is necessary to invent a multi-layer prefabricated steel structure modular housing node connection device to solve the above problems. Utility Model Content

[0006] The purpose of this utility model is to provide a node connection device for multi-layer prefabricated steel structure modular houses, so as to solve the problem that the connecting plate cannot effectively connect the modular steel frame when certain errors easily occur after the modular steel frame is installed, which has certain limitations.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a multi-layer prefabricated steel structure modular house node connection device, including steel pipe columns, with a first connecting plate welded and fixedly connected to the end of the steel pipe column, and a diagonal bracing plate welded between the steel pipe column and the first connecting plate. The surface of the first connecting plate is provided with multiple sets of first connecting holes, and a connector is provided between the upper and lower sets of steel pipe columns. The connector includes a second connecting plate, a connecting column, a second connecting hole, a third connecting hole, a connecting rod, a positioning groove, a first adjusting block, a first connecting sleeve, an adjusting screw, a positioning block, a connecting block, and a fourth connecting hole.

[0008] By adopting the above technical solution, high-strength bolts are provided between the first connecting hole, the second connecting hole, the third connecting hole and the fourth connecting hole. The second connecting plate and the connecting column are set between the upper and lower sets of steel pipe columns and fixed by high-strength bolts.

[0013] Optionally, the adjusting screw is slidably connected to the connecting rod, and a connecting block is fixedly connected to the opposite ends of the connecting rod and the adjusting screw, and the fourth connecting hole is opened on the surface of the connecting block.

[0014] By adopting the above technical solution, the adjusting screw can slide inside the connecting rod to extend the connecting rod. At the same time, the high-strength bolt passes through the fourth connecting hole and the third connecting hole, which can lock and fix the connecting block to the second connecting plate. With the connecting rod and the adjusting screw, two sets of second connecting plates at different distances can be connected and fixed, thereby connecting two adjacent sets of steel pipe columns.

[0015] Optionally, positioning grooves are provided on both the front and rear sides of the connecting rod surface, and two sets of positioning blocks are fixedly connected to the left end of the adjusting screw, with the positioning blocks slidably connected to the positioning grooves.

[0016] By adopting the above technical solution, the positioning block slides inside the positioning groove, which improves the stability of the adjusting screw during the extension and retraction process, and limits the adjusting screw to prevent it from rotating.

[0017] Optionally, the first adjusting block is rotatably connected to the right end of the connecting rod, the first connecting sleeve is fixedly connected to the right end of the first adjusting block, and the first connecting sleeve is threadedly connected to the adjusting screw.

This utility model first fixes the second connecting plate between the upper and lower sets of steel pipe columns. After all the steel pipe columns on the left and right sides are installed, the connecting rod is placed between the two adjacent sets of second connecting plates. By rotating the first adjusting block, the adjusting screw is pushed outward in conjunction with the first connecting sleeve to extend the connecting rod. Then, the connecting blocks at both ends are locked and fixed to the two adjacent sets of second connecting plates, thereby connecting and fixing the two adjacent sets of steel pipe columns. It can be used for two sets of steel pipe columns with different distances, improving the convenience of operation and the adaptability of the connecting parts. 2. By rotating the second adjusting block to the left, the second connecting sleeve is fitted onto the outside of the first connecting sleeve, and in conjunction with the positioning screw, the first connecting sleeve and the second connecting sleeve are locked together.

[0025] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0026] This utility model provides, for example Figures 1 to 6 The diagram shows a multi-layer prefabricated steel structure modular house node connection device, including a steel pipe column 1. A first connecting plate 11 is welded and fixed to the end of the steel pipe column 1. A diagonal bracing plate 13 is welded between the steel pipe column 1 and the first connecting plate 11. Multiple sets of first connecting holes 12 are opened on the surface of the first connecting plate 11. A connector 2 is provided between the upper and lower sets of steel pipe columns 1. The connector 2 includes a second connecting plate 21, a connecting column 22, a second connecting hole 23, a third connecting hole 24, a connecting rod 25, a positioning groove 251, a first adjusting block 252, a first connecting sleeve 253, an adjusting screw 26, a positioning block 261, a connecting block 27, and a fourth connecting hole 28. The connecting column 22 is welded and fixed to the middle of the second connecting plate 21. The connecting column 22 is inserted and fixed to the steel pipe column 1. Multiple sets of second connecting holes 23 and third connecting holes 24 are opened on the surface of the second connecting plate 21. The first connecting holes 12 and the second connecting holes 23 are located on the same axis.

[0027] The diagonal bracing plate 13 improves the stability of the welding between the first connecting plate 11 and the steel pipe column 1. During the installation of the steel pipe column 1, the lower steel pipe column 1 is installed first, then the connecting column 22 is inserted into the upper end of the steel pipe column 1, and then the lower end of the upper steel pipe column 1 is fitted onto the upper end of the connecting column 22. At this time, the second connecting plate 21 is located between the upper and lower sets of steel pipe columns 1. Then, high-strength bolts are inserted through the first connecting holes 12 on the surface of the upper and lower sets of first connecting plates 11 and the second connecting holes 23 on the surface of the second connecting plate 21 to lock and fix the first connecting plate 11 and the second connecting plate 21, thereby connecting and fixing the upper and lower sets of steel pipe columns 1 and improving the stability of the connection between the upper and lower sets of steel pipe columns 1.

[0028] In addition, when it is necessary to connect and fix two adjacent sets of steel pipe columns 1, the connecting rod 25 and the adjusting screw 26 are fixed between the two adjacent sets of second connecting plates 21. At this time, the connecting rod 25, the adjusting screw 26 and the second connecting plate 21 are used to connect the two adjacent sets of steel pipe columns 1, so that the two adjacent sets of steel pipe columns 1 are combined into a whole, which effectively improves the structural strength of the steel structure assembly block and the stability of the building.

[0029] See Figure 3 , Figure 5 and Figure 6 The adjusting screw 26 is slidably connected to the connecting rod 25. The opposite ends of the connecting rod 25 and the adjusting screw 26 are fixedly connected to the connecting block 27. The fourth connecting hole 28 is opened on the surface of the connecting block 27. The front and rear sides of the surface of the connecting rod 25 are provided with positioning grooves 251. The left end of the adjusting screw 26 is fixedly connected to two sets of positioning blocks 261. The positioning blocks 261 are slidably connected to the positioning grooves 251. The first adjusting block 252 is rotatably connected to the right end of the connecting rod 25. The first connecting sleeve 253 is fixedly connected to the right end of the first adjusting block 252. The first connecting sleeve 253 is threadedly connected to the adjusting screw 26.

[0030] Specifically, during the connection of the connecting rod 25 and the adjusting screw 26, the connecting block 27 at the left end of the connecting rod 25 is first clamped onto the surface of the second connecting plate 21 on the left. At this time, the high-strength bolt is passed through the third connecting hole 24 and the fourth connecting hole 28 on the left to lock the left connecting block 27 to the second connecting plate 21 on the left. Then, according to the distance between the two sets of second connecting plates 21, the first adjusting block 252 and the first connecting sleeve 253 are rotated. The first adjusting block 252 and the first connecting sleeve 253 cooperate to push the adjusting screw 26 to the right until the right connecting block 27 is clamped onto the surface of the second connecting plate 21 on the right. At this time, the high-strength bolt is used to lock the right connecting block 27 to the second connecting plate 21 on the right, thereby connecting and fixing the two adjacent sets of steel pipe columns 1, which can adapt to two sets of steel pipe columns 1 at different distances.

[0031] Meanwhile, after the connecting rod 25 and the adjusting screw 26 are connected to the two adjacent sets of steel pipe columns 1, the first adjusting block 252 and the first connecting sleeve 253 are rotated in the opposite direction to retract the adjusting screw 26 inward by a certain distance, thereby locking the adjusting screw 26 and improving the stability of the connection.

[0032] After the uppermost steel pipe column 1 is completed, the connecting rod 25 and the adjusting screw 26 can be connected and fixed to the first connecting plate 11 at the upper end of the steel pipe column 1, so that the upper ends of the two adjacent sets of steel pipe columns 1 can be connected and fixed. There is no need to connect the second connecting plate 21, which improves the convenience of installation.

[0033] See Figure 5 and Figure 6 The first connecting sleeve 253 has multiple sets of threaded holes 254 on its side. The threaded holes 254 are internally threaded with positioning screws 255. The surface of the adjusting screw 26 is threaded with a second adjusting block 262. The left end of the second adjusting block 262 is fixedly connected with a second connecting sleeve 263. The surface of the second connecting sleeve 263 has multiple sets of limiting grooves 264.

[0034] In addition, after locking and fixing the connecting rod 25 and the adjusting screw 26, the second adjusting block 262 and the second connecting sleeve 263 are rotated to the left so that the second connecting sleeve 263 covers the surface of the first connecting sleeve 253. At this time, the positioning screw 255 passes through the limiting groove 264 and is threadedly connected to the threaded hole 254, thereby locking and fixing the first connecting sleeve 253 and the second connecting sleeve 263, connecting the first connecting sleeve 253 and the second adjusting block 262 into a whole. The cooperation of the first connecting sleeve 253 and the second adjusting block 262 further improves the stability of the adjusting screw 26.

[0035] The working principle of this utility model is as follows: By placing the connecting rod 25 between two adjacent sets of second connecting plates 21, and by rotating the first adjusting block 252, the adjusting screw 26 is pushed outward in conjunction with the first connecting sleeve 253, extending the connecting rod 25. Then, the connecting blocks 27 at both ends are locked and fixed to the two adjacent sets of second connecting plates 21, thereby connecting and fixing the two adjacent sets of steel pipe columns 1. This can be applied to two sets of steel pipe columns 1 at different distances, improving the convenience of operation and the adaptability of the connecting parts 2. At the same time, by rotating the second adjusting block 262 to the left, the second connecting sleeve 263 is fitted onto the outside of the first connecting sleeve 253, and in conjunction with the positioning screw 255, the first connecting sleeve 253 and the second connecting sleeve 263 are locked. At this time, the first connecting sleeve 253 and the second adjusting block 262 cooperate to further improve the stability of the adjusting screw 26.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the utility model.
